SHEET RECEIVING AND FEEDING MECHANISM.

Applicatibn filed January 12, 1923. Serial' 1%. 612,321.

To all whom, it may concern:

Be it known that I, ALBERT BROADMEYER, a citizen of the United States, residing at Harrisburg, in the county ofiDauphin and 1 State of Pennsylvania, have invented certain new and useful Improvements in Sheet Receiving and Feeding Mechanisms, of which the following is a specification.

While the present invention is peculiarly useful in connection with ruling machines of; the type known as Dual-L, in which the sheets after being ruled in one direction by one apparatus, are fed to another ruling apparatus arranged at right angles thereto for ruling lines transversely to the first lines ruled, there are features of the invention that are useful in connection with trating the sheet-receiving other types of machines. I a

The object is to provide means for receiving sheets moving in a predetermined direction and startin said sheets in an angular direction, sai means being simple and practical and capable of being'proper ly timed, so that each sheet will be removed from the path of the succeeding sheet and there will be 'no interference or piling up between such sheets.

In the accompanying drawings V Figure 1 is a plan view of the above described type of ruling machine, and illusand delivering means, I y

Figure 2 is a longitudinal sectional View taken substantially on the line 2-2 of Figure 1 Figure 3 is a sectional view on the line 33 of Figure 2,

Figure 4 is a plan view of and delivering means.

Figures 5 and 6 are detail sectional views, respectively, on the lines 55 and 66 of Figure .4. p

In the accompanying drawings,the first of the two ruling machines is designated generally by the reference numeral 7, and the second machine by the reference numeral 8. These two machines may be of any well known or desired character, and are shown diagrammatically. The sheets the receiving is so placed that the ends, said brackets being slidable on guide bars 13. The adjustment of the stop plate 11 along the supporting bars 10 is effected by sprocket chains or cable members 14 that pass around sprocket wheels 15 located below the end portions of the supporting bars 10, said sprocket chains being connected to the brackets 12. By moving these chains, obviously the plate 11 can be moved to different positions. For the purpose of effecting the movement of the sheets along the supporting bars 10, endless tapes 16.. are employed that pass around rollers 17 at the ends of the bars. The rollers 17 at the rear end of the machineare carried by a shaft 18 that is belted, as illustrated at 19 to one of the rollers 20, around which the conveying belt and cords of the machine operate. f

Located in the rear end of the machine 7 alongside the supporting bars 10 and adjacent to the juncture of the machine 8 with the machine 7, is a sheet-moving member in the form of a roller 21 that is disposed longitudinally of the direction of movement of the sheets over the bars 10. This roller 21 is continuously driven from the second machine 8 through suitable gearing and beltin illustrated generally at 22 in Figure 1. t margins of the sheets delivered on to the supporting rods 10 will overlie said roller, as indicated at A in Figures 3 and 6. Arranged longitudinally above the roller 21 is a shaft 23 that is pro-1 vided with one or more gripping cams 24. The perip eral portion of each cam from B to C, as shown in Figure 6, is on the radius of a circle that will cause said portion to coact with the roller 21 and grip the margin of the sheet A againstthe same.

The rcfrom the roller 21.

maining portion of the cam is of considerably less diameter, and as indicated in Figure 6, is thus spaced a considerable distance The'shaft 23 furthermore carries at one end a friction wheel 25, the radius of which is such that it will also coact directly with the roller 21, but which has a cut-out portion 26 that leaves a space between said roller 21 and wheel 25 when the cams 24 are out of coaction with the roller 21. This will be clear by a comparison of Figures 5 and 6. The shaft 23 is free to rotate and it is overbalance'd by the utilization of weights 27 and 28 carried by the cams 24 and friction wheel 25. Said shaft is, however, normally held against movement, and 'to'this end it is provided with a pin 29 adapted to be engaged by one arm 30 of a, stop lever pivoted on the frame of the machine 7, as shown at 31,.and having its other end 32 coacting with a cam 33. This cam 33 is mounted on a shaft 34 journaled transversely in the frame of the machine 7,

and geared as shown at 35,ein Figure 1, to

delivered on to the rods 10, as will be evident. Each is carried along the rods 10 by the tapes 16'until stopped by the plate 11. During this movement, although the roller 21 is in operation, the shaft 23 is stationary with the cams 24 raised. Thecontrolling cam 33 for the stop lever 30-32 is continuously in operation and is timed so that when a sheet is positioned against the stop 11, the stop arm 30 is raised. This movement is occasioned by the arm 32 riding against the flat portion of the cam 33 and a spring 32 serves to swing the lever and raise the arm 30 out of engagement with the pin 29. As soon as this takes place the shaft 23 is released and the weights 27 and 28 will cause an initial rotation of the shaft and of the friction wheel 25 and cams 24. Almost immediately the periphery of the friction wheel will engage the roller 21 and continue the rotation of said shaft. As this movement takes place the cams 24 will move into coaction with the roller 21, thereby gripping the paper sheet A thereagainst and starting its movement at right angles and into feed ing engagement with the rollers 37 38' and 39. The shaft 23 makes one complete rotation. By that time the stop arm 30 has been again depressed into the path of the pin 29 and the gripping cams again become inactive. By this time, however, the sheet has been seized by the feeding mechanism of the second machine 8, and is carried off thereby. This 0 eration takesplace periodically as succeedi sheets are delivered.

From t 1e foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size. shape, proportion and minor details of con struction may be resorted to without departmg from the spirit or sacrificing any of the advantages of the invention.
