Beitknown that l'fJo'sEPH KLEIDMANN, a

' subj'ectof the '(lzar'cf Russia, and resident of the city of New Yorkjin the 'countyof New '1 York and State ofNew' York, have invented certain new and useful lmproven'ients in {Papa- Fe'edingll/lachiries; of which the following" is a specification.

The present 'invention relates to paper feeding machines which are adapted for use on printing presses, ruling machines, and on similar apparatus by means of which single sheets are fed regularorder of succession from a pile or stack of paper, suitably arrang'ed'on a'table'located near to the apparatus. Among other devices there have been used heretofore for this purpose feeding cylinders, secured to' a' bracket, suitably ar' ranged on a shaft, to which bracket had been fastened one or more fingers, which latter serve the purpose of allowing the feeding cylinders to engage the sheets at a suitable "distance from the front edge thereof and then'feed the sameto devices which deliver them to the'printing press or to a similar machine. One serious defect of this device consists ilithe fact that the fingers, mentioned hereinbefore, tear the paper on'it's front edge, for the reason that the whole weight of the feeding cylinders rests on these fingers and thus on the paper, and the fingers are thereby liable to tear the latter when reachin the front edge of'the paper sheet,

"in which position the cylinders and fingers rest on one'sheetonly. Another serious defect is due to the arrangement of the cylin- 'ders' relative to the fingers, or more: particula rly due to the fact that the cylinder'sare normally out of engagement with the paper and engage the same only when the fingers are disengaged with the same, and since certain machines require a great speed, it is obvious that the feedingcylinders will at such a great speed not be able to engage the paper "same at all.

" :fore mentioned, and its lirst object is to construct a""-s1m'ple and inexpensive device,

whichfis a'd'aptedtoseparate in regular suc- "c'ession'singlesheets from a stack of paper, suitably arranged near to the printing press.

Another object ofthe invention is to provide feeding rollers, which rest normally on the paper, but becomeoperative only at a certainand predetermined distance from the edge of the paper, preventing thus the fingers, to which'said rollers are attached, from tearing the sheets of paper. I

A further object of the invention is to provide meanswhich hold the other sheets of paper from movement, while the top sheetis being advanced and removed.

' A still further object of the invention is to accomplish all the aforesaid operations in a positive, efiicient and simple manner, and in a continuous cycle of operation.

These and other objects'and advantages will more fully appear in reading the specification and from the inspection of the drawings forming part of this application.

' Broadlyspeaking, 'upon the main shaft of the apparatus are mounted a plurality of cams or eccentrics, which operate the feeding rollers, to which are attachedfingers which rest together with the rollers on the sheet of paper and allow the rollers to rotate as long as the fingers are engaged with the aper. As soon as the fingers are disengage with the paper, the rotation of the rollers is stopped, whereby the aper is fed to a mechanism, transporting t e sheets to the printing press or similar device.

The invention consists further of the combination and arrangement of parts, the construction'of th'edevice and the location of the mechanisnn'which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the improved apparatus and Fig. 2 a front view'of amodification of the apparatus. Figs. 3 and 4 are details of construction, showing the device which holds the other sheets of paper from movement, while the top sheet is being advanced and removed. Fi 5 is a detail of construction, showing the location'oi the advancing means at or about the beginning of its forward movement, Fig. 6 is a similar view of the same mechanism, showing its position at that point where thefeeding rollers become operative, Fig. 7 is a similar viewofthe device, showing the outermostposition ofthe advancing means and Fig. 8 shows the advancing means in their raised position and about to start backward. Fig. 9 is a perspective view of the advancing means. Figs. 10, 11 and 11 illustrate details of construction. Figs. 12, 13, 14, 15 and 16 are detail views of modifications of the advancing means.

in the drawings, 1 designates one of a pair of the side frames of the feeding machine, connected by means of screws 2, 2, to the side frames 3 of the printing press. The side frames 1 may be connected by any suitable members, as, for instance, in the present case by means of tie-rods 4.

The stack of paper is indicated in the drawings at 5 and is supported on a table 6, which is automatically raised by means, hereinafter to be described. The stack of paper is guided in its upward movement by a transverse vertical wall 7 having a forwardly bent lip 8, unto which the paper is brought by the feeding mechanism, which forms an essential part of the present invention.

The main shaft 9 of the apparatus is journaled in suitable bearings in the frame and is rotated from the cylinder shaft 10 of the printing press by any suitable means, such as, for instance, sprocket-wheels 11 and 12,-

mounted on the shafts 10 and 9, respectively, and a chain 13, transmitting the rotation of the cylinder shaft 10 to the main shaft 9 of the apparatus. This main shaft 9 operates through the medium of suitable intermediate means the feeding rollers of the apparatus.

in order that the operation of and the connection between the feeding roller carrying means and the main shaft of the ap aratus be more clearly understood, first t e construction of the feeding rollers and the principle upon which they work will be described.

The sheet feeding or advancing means comprise one or more rollers mounted on a forked lever, which lever is provided with a finger, which allows the roller to rotate, or arrests the rotation of the same, so that it may act upon the sheet of paper and convey the same to means which transport the sheets to the printing press. The principle of operation of these feed rollers or advancing means is the following: The rollers come into contact with the paper and are moved forward, rotating until a predetermined point from the front edge of the paper, where their rotation is stopped. As far as this the paper is not advanced, due to the rolling motion of the rollers. Since, however, these rollers are provided with a friction covering, and the top sheet rests on paper or on a friction covering, somewhat smoother than the covering of the rollers, it is obvious that the top sheet will be separated from the stack of paper and moved forward as soon as the rotation of the rollers is arrested. The rollers are then disengage the paper and move forward but do not advance the sheet until their rotation is stopped; advance the sheet and are then raised, moved backward and then again brought into engagement with the paper.

The means for effecting this motion will be 7 hereinafter more fully described.

In Figs. 5 to 9 of the drawings, the different stages of operation of the advancing means are shown. The feeding roller 14 is loosely mounted upon a shaft 15, which in turn is rotatably ournaled on a forked lever 16, loosely carried by a lever 17, which is adj ustably mounted on an oscillating and alternating shaft 18. As mentioned hereinbefore, the roller 14 is loosely mounted on the shaft 15; the roller would thus not necessarily participate in the rotation of the shaft. In order that the roller should rotate with the shaft, but still be flexibly connected to the same, a spring 19 is arranged on the shaft,

engaging the roller 15 and an adjustable washer 20, by means of which the tension of said spring may be adjusted so that the connection between the roller and shaft be more or less rigid. The roller 14 is provided with a friction covering 21, preferably made of rubber, or of any suitable material, the coefficient of friction of which is greater than that of paper upon paper. FiXedly secured to the shaft 15 is furthermore a ratchet 22, adapted to be engaged by a projection 23 of a lever 24, pivoted at 25 to the forked lever 16. The lever 24 carries on its free end a finger 26, adjustably secured thereto. Normally, that is when the finger 26 rests upon the surface of the top sheet, the projection 23 does not engage the ratchet 22, and thus the roller 14 is allowed to rotate freely, but as soon as the finger 26 is disengaged with the paper and allowed to fall down, the projection 23 engages the ratchet, whereby its rotation is stopped and the friction between the paper and the roller carries the top sheet forward within the reach of the trans oorting means, hereinafter to be describe shaft 18 is reciprocably mounted in horizontal guides 180 and has attached thereto a lever 27, carrying a roller 28, slidably arranged in a substantially horizontal guide 29, which in turn is slidably arranged in a substantially vertical guide 30. It will thus be seen that in alternating the shaft 18 and raising and lowering the guide 29, the feeding roller will be moved forward, raised, moved backward and lowered, as the guide is raised and lowered and the shaft is moved to and fro. in order to alternate the shaft 18, the same is engaged by an arm 31, piv- The r 16, relative to side framest o-f the.machine.v To. this. rockshaft is rigidly secured an arm 3.4, engaging the. properly constructed groove 35 of a cam 36, fixedly secured upon the. main shaft 9. By means 'oftheseconnections, the rollers 14 ar'ealternated upon the surface of the paper, whileby means of. the-cam36, carried; by the shaft. 9, and the lever 37', pivoted at 38 and engaging the. horizontal guide 29: and the cam 36, the. rollers are lowered, and raised. The cam36 doesnot operate upon the lever 37' until; the. rock-shaft has. caused? the shaft l8 to. move toward. the front edge of; the sheet of; paper toits outermost position, in which position the. rollers 14. have brought the sheet of paper within the reach of the transporting mechanism, hereinafter to be described. The cam 36 acts then upon. the lever-37, lifting thereby the horizontal. guide 29, whereby, the shaft 1:8 isgivena turn and the rollers. 14. arev disengaged with the top sheet of the ile of paper. The cam. 36 keeps the gui, e 29 in, its, elevated position until the shaft 18 is brought by the groove 35. of; the cam 36 and the mechanism operating therewith into its innermost position, at which place the spring 364, shown. in Fig. 2 of the drawings, brings the guide 29 back to its lower position, giving thereby the shaft 18.; a. turnso that the rollers 14. engage. again the to psheet of, the. pile of, paper.

The angular osition of thev forked levers e shaft. 18 may be adjusted by meansof a set screw 39, engaging a prO- jection 40, carried by the lever 17. A spring 47; engages theprojections40 and the lever 16 in order to keeptherollers incontact with the paper and to exert the desireddegree of pressure on the surface of-the. paper. It is obvious that the rollers. should. engage the paper: always undera certain predetermined angle in order that their operationshould be the most'effectve. The set screw. 39' predetermines this angle, and is usually set so that. the roller will engage the paper under nearly themost efiective angle, even when the paperisnot raisedto its normal level.

To theoscillating shaft 18 is rigidly attached a,rod 48, carrying an adjustable arm 49, forkedat- 50. In this forked end of the arm- 49 is mounteda roller 51 and means in: dicated at 52 whichwill allow the roller to rotatewhen the. same moves with the feeding rollersforwardly, but prevents. the rota: tion of the same in the other direction. The distance between thefeeding rollers. and the roller-51 issuch, that the roller; 51 engages always. the sheet next tothe .top sheet of the stack of paper. When, therefore, the feeding rollers move forward, the roller 51 will engage the sheet which lies under the top sheet, and will thus prevent; the removal of the same. Should, however, for-somereason, thesecondsheetmovewith thetop sheet, it will tend to move the roller 51 backward,

which turn effects. a brakingor retarding action. on this sheet,and prevents thus. its re: moval. The roller 51 may be provided ob,- viously, with a. friction covering.

On, the lip 8 of the transverse wall 7,. here,- inbefore referred to, is. arranged a slightly inclined table 53, having friction strips 54, arranged under the rollers 14, which are preferably made of rubber, the friction surface. of which is somewhat smoother than hat of the friction roller 14, orin other words, the coefficient of: friction of the feeding rollers 14 has a greater value than that of the friction strips 54. Adjacent to these friction stripsand in thepath of the fingers 26 are formed recesses 55. in the: plate 53; into which thefingers26 lower when moved beyond the front edge of the top sheet. The object of this construction is to arrest, the rotation of the rollers. 14 atapredetermined point; from the front edge of the sheets, so as to. move the top. sheet forward. The top sheet of the stack of paper is advanced by the rollers until it is Within the reach of the conveying means, consisting of rollers 56, mounted on a shaft 57, rotated by means of a chain 58 and sprocket-wheelv 59 from the main shaft of the apparatus, and feeding belts 60, running over rollers 61, journaled in brackets 62, which are attached to the inclined table 68, on which the sheet slides unto the cylinder of the printing press, Pressure. rollers 64 rest normally on the rollers 56, and are mounted on a lever 65, pivoted at 66, the free end of which levers carry rollers 67 in contact with cams 68, arranged on the main camshaft 9 of the apparatus. A second set of pressure rollers 69 are carried byrods 70, pivoted at 66 to the levers 65, carrying the pressure rollers; 64. It is obvious that the purpose of the cams 68 is to raise and lower the pressure rollers 64. at times when the front edge of the top sheet of the stack of paper reaches the rollers 56. The feed bands deliver the sheets to the cylinder of theprinting press, it being, of course, obvious that means must be provided, whereby the sheet is brought into the proper position relative to the cylinder. This means isindicated at 71, and is operated by means of the outer surface of the cam 36 through intermediary of 2. connect ing rod 74, secured to an arm 7 5, having a roller 76 in contact with thecam 86. These adjusting means form the subject matter of another application and are here only indicated inorder to complete the description of the machine. In order to keep the other sheetsback. asthe top sheet is being fed off, a gripper is provided, which is carried by a rod 77, journaled at 78 and 79 upon the frame of the machine and compris ng an arm 80, carried by the rod 77, towhich arm is attached a connecting rodj81, to the latter being pivoted a finger 82, normally kept upon the stack of paper by means of a spring 83. The shaft 77 is operatively connected to a cam 84, mounted upon the main shaft of the machine. The connection between the cam and the rod 77 is made by means of an arm 85, rigidly secured to the rod 77 and engaged by the forked end of a connecting rod 86, which latter carries a roller 87, operatively engaging the cam 84. It will be easily seen that when the roller 87 is engaged by the cam 84, the finger 82 is lifted, or in other words, disengaged with the paper and allows the top sheet to be removed, but as soon as the top sheet is moved for a distance, the finger 82 engages the other sheets just back of the rear edge of the top sheet of the paper and prevents thus the movement of the same.

As mentioned hereinbefore, the stack of paper is supported on a table 6, which is automatically raised by means of a device, which forms the subject matter of another application for Letters Patent. More particularly, the table is supported by endless lines 88 and 89, which latter is secured to a pulley 90, mounted on a shaft 91, carrying a worm gear 92 in mesh with a worm 93, which is operated by means in contact with the stack of paper.

Frequently mutilated or torn sheets are contained in the stack of paper, and it is obvious that when such sheets are fed to the printing press, serious troubles arise. More particularly the cylinder prints upon the paper and at the mutilated places upon the support of the paper; when thus the next sheet is printed, the reverse side of the same is usually inked in by the ink being upon the support of the paper at places where the )re ceding sheet was mutilated or torn. t is thus obvious that means should be provided which stop the operation of the printing press and the feeding machine, when a mutilatedsheet is fed to the press. For this purpose an oscillating arm 96 is mounted upon the frame of the machine, and connected by means of a, preferably, rigid connection, shown at 97, to the power transmitting apparatus, located between the main shaft of the printing press and the shaft of the motor or any other suitable device, operating the printing press. The arm 97 is normally kept in this position, that is in a position, whereby the two shafts, hereinbefore mentioned, are connected, by means of a bellcrank 98, pivoted at 99, and being provided with a nose 100, engaging a projection 101 of the lever 96. In order to keep the bellcrank 99 in engagement with the lever 96, a lug 102 is provided, pivoted at 103. The free end of this lug forms the armature 104 of an electro-magnet 105. One end of the winding of the electro-magnet is connected to the frame of the machine, while its other end leads to a battery 105, the free terminal of which is connected preferably to the pressure rollers 64 and tie adjusting means 71. The bellcrank 98 holds the lever 96 in its operative position against the tension of a spring 106, connected to the lever 96 and the frame of the machine. Normally, that is when a whole sheet of paper passes through the conveying and pressure rollers, itinsulates the pressure rollers from the frame of the machine. Should, however, the sheet be torn or mutilated, a contact is closed from the frame, through the magnet, through the battery to the pressure roller and thus to the conveying rollers. The electro-magnet is thus energized, and attracts the armature 104, allowing the spring 98 to act, whereby the nose 100 is disengaged from the projection 101 of the lever 96, and the spring 106 is adapted to act, shifting thus the lever and disconnecting the power transmitting apparatus, whereby the machine will immediately come to rest.

The operation of the device is as follows: The sheets of the stack of paper are moved by the feeding rollers forward unto the slightly inclined table 53, it being obvious that the top sheet owing to the slight inclination is moved further outward than the suhsequena, sheets. This position can be imparted to the sheets either by hand or by the machine proper, when worked. If now the machine is started and thus the camshaft 9 rotated,

the feeding rollers will be first in the position shown in Fig. 5 of the drawings, that is the fingers 26 and the rollers 14 rest on the top sheet, and thus the projections 23 of the finger carrying arms 24 do not engage the ratchets. The rollers 14 will, therefore, rotate freely, and do thus not move the paper. At the same time roller 51 engages the sheet next to the top sheet and moves thereon in the manner, hereintefore described. When now the fingers 26 reach the front edge of the top sheet with their rear edge, the fingers will fall down into the recesses 55 and thus the projections 23 will engage the ratchets, (Fig. 6 of the drawings), whereby the rotation of the rollers is stopped, and the latter being provided with a friction covering of more or less adhesive material, will carry forward the top sheet. The sheets lying underneath the top sheet are prevented from movement by the friction covering 54, arranged in the path of the rollers, which covering produces a friction greater than that between two subsequent sheets. On the other hand, as soon as the top sheet starts its movement, the finger 82 engages the sheet lying under the top sheet and keeps the same in position. W hen the feeding rollers have reached their outermost position, as shown in Fig. 7, the top sheet is within the reach of the conveying rollers 56, at which time the pressure rollers 64 are moved downwards, whereby the sheet is conveyed unto the printing press (Fig. 8 of the drawings). As soon as the feeding rollers 56 engage the sheet of paper, the fingers and feeding rollers 14 are moved upwards and backwards, into contact with the next sheet.

Attention is called to the fact, that the construction of the cam groove is such, that the rollers 14 and the fingers contact with and are disengaged from the paper with a speed which is practically equal to zero.

Vv hen for some reason the friction strips are not covered by a sheet of paper, and no forked end of the rod 109,

sheet is advanced, it is obvious that the friction covering of the rollers 14 will slide on the friction strips 54, whereby the arms, supporting the rollers 14, would be liable to break or to stop the operation of the machine. This is prevented by the flexible connection between the rollers and the shaft of the same, as hereinbefore described.

A modification of the feeding rollers and finger is shown in Figs. 12 to 15 of the drawings. In this case a roller 107 is mounted on the forked end 108 of the bar 109, which latter is mounged in the manner, hereinbefore described, upon an arm 17, engaging the shaft 18. The. roller 107 is again provided with a friction covering 21. A finger 110 is adjustably mounted upon a U-shaped memher 111, loosely mounted on the shaft 112 of the roller 107, and carrying loosely behind the roller a shaft 113, to which is fixedly se cured a pawl 114. Normally, that is when the finger and roller rest on the pa )er, the

awl 114 rests against the back wa of the As the finger 110 is lowered into the recess 55, the pawl 114 is forced by the weight of the finger and U- shaped bar 111 against the roller 107 and stops thus the rotation of the same. An other modification of these feeding rollers and fingers is shown in Fig. 16 of the drawings, in which a pawl 115 is arranged in front of the rollers, the operation of the same being, of course, the same as the one, hereinbefore described. I

From the inspection of the drawings, it will be understood that the machine may operate upon sheets of different thicknesses and size, without changing in any way whatever the position of the parts of the machine. It is, on the other hand, obvious that many minor changes may be made in the construc tion of the parts and assembling the same without departing from the spirit and scope of the invention. For instance, one modification is shown in Fig. 11 of the drawings, in which the lever 27 on the shaft 18 is provided with two rollers 116 and 117, engaging a guide 118, which is mounted on a reciprocating arm 119, sliding in the guides 120 and operated by the cam 36, hereinbefore described.

Another modification is shown in Fig. 2 of the drawings, in which the shaft 18 is provided with rollers 181 and 182, engaging the horizontal. guides 183, attached to the side frames 1,1 of the machine.
