This invention relates broadly to sheet handling apparatus and more particularly to apparatus for handling metal sheets in a sheet mill. llt relates still more particularlyto an apparatus for moving sheets which are piled one upon another to a position in which they are disposed on edge.

ln the operation of a sheet mill there are certain steps in the handling of the sheets il@ which have heretofore been the source of considerable diiliculty and have occasioned undue labor and expense. Among these operations is thatin which the sheets are moved from the annealing furnace to the pickling vat. When the sheets are pack-annealed, they are removed from the annealing furnace in apa/ck or ile. lin order to thoroughly and properly pic le the sheets, it is necessary that they e separated before being placed into the pickling vat, so that the piclzlin liquor will completely surround each indivi ual sheet.

lt has been the custom to turn up each sheet from the pack or pile comingl from the annealing furnace and position each sheet onV performs the function and which dis enses with the labor of a number of men. t conseguently increases the output of the. mill and re uces the cost of manufacture of the sheets.

While the apparatus is particularly adapted for moving sheets from a pile and turning them up on edge preparatory to going to the pickling vat, it is adaptable for many other I purposes, .its utility being by nomeans limited to the single operation referred to.

Y We provide sheet handling apparatus, comprising, in combination, means for separating a number of sheets from the ton of a pile 31929. `Serial No. 377,113.

of sheets, means for moving such sheets from the top of said pile, and means for turning the sheets on edge. We further provide sheet handling apparatus, comprising a carriage carrying substantially vertically adjustable means for engaging a number of sheets at the top of a pile, such carriage being substantially horizontally movable to move the sheets from the pile.

. Other objects and. advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

ln the accompan g drawings we have shown a present pre erred embodiment of the invention, wherein 4 lligure 1 is a longitudinal elevational view of a sheet handling apparatus,

Fi re 2 is a view similar to Fig. 1, but showing the' parts'in a different operative position,

Figure 3 is a 4top plan view of the sheet handling apparatus shown in Figs. 1 and 2,

Figure 4 is a detail view to enlarged scale,

and

'Figure 5 is a further detail view also to 'enlarged scale. l Referring more particularly to the drawings, reference numeral 2 designates generally a seriesof I-beams or supports, upon which aremounted rails 3 forming a track. Mounted upon the rails 3, through wheels 4, is a carriage 5. The top of the carriage 5 is provided with rails 6, upon which is mounted, through wheels 7, a second carriage 8. Connected to thecarriage 8 and extending through thecarriage 5 is a frame 9, having at kits lower extremity a cross-rod 10 which projects laterally beneath the heads of the rails 3, whereby to insure that both of the frames 5 and 8 remain in place with respect thereto.V

.lournalled infthe frame 3 is a air of " cross-shafts 11 and 12, the-latter o which is provided with'a hand-wheel 13. To each of the shafts 11 and 12 is keyed a bevel gear 14 and 1'5, respectively. Mounted in the frame 3 are a pair of cross-supports 16 and 17, in which is journalled a longitudinal shaft 13 having keyed thereto at its apposite en- 12 adjacent the opposite sides of the frame 3 are gear wheels 21,22, 23, and 24, respectively. Connected with the interior of the frame 3eoutside the shafts 11 and 12 and co operating with the respective gear wheels are guides 25, 26, 27, and' 28, respectively.

Passing through the respective guides andl meshing with the respective gear wheels are four racks 29, 30, 31, and 32, respectively.

These racks are connected at their upper exaro tremit'ies to a common frame 33. Also connected with the frame 33 is a pair of downwardly extending guidel members 34 and 35, respectively. Connected with the frame 8 are -oppositely disposed straps 36 and 37, respectively, in which the guide members 34 and are received.

Rotation of the hand-wheel 13 causes rotation in opposite directions of the gear wheels on the shafts 11 and 12 which gear wheels, meshing with the racks 29, 30, 31, and 32 cause upward or-downward movement of the frame 33 with respect to the carriage 8, depending upon the direction of rotation of the hand-wheel 13. The frame 33 is guided with respect to the carriage 8 by the four racks and by the guidemembers 34 and 35.

Journalled in the frame 33 is a cross-shaft 38 to which is keyed a hand-wheel 39. Also keyed to the shaft 38 is a gear wheel 40.

Surrounding the shaft 38 and cooperating vwith the gear wheel 40 is a guiding strap 41.

Passing through the guiding strap 41( and meshing with the gear wheel 40 is a rack 42. Rotation of the hand-wheel 39 causes rotation of the shaft 38 and consequently of the gear wheel 40 which, by reason of its meshing relationship with the rack 42, causes longitudinal movement thereof. The rack 42 has connected to its outer extremity a sep-- arating device 43, the function of which will be presently described. Such device is relatively thin and fiat andlis provided with a substantially pointed extremity 44.

' Journalled in the frame33 is a cross-shaft 45, having keyed thereto a hand-wheel 46. Alsokeyed to the cross-shaft45 is a gear wheel 47. Connected with the frame 33 is a cross-brace 48 with which is connected a guiding strap 49, which strap also encircles the shaft 45 and cooperates with the gear wheel, 47 Passing through the guiding strap 49 and meshing with the gear Wheel 47' is a rack 50, having connected to its lower extremity a guiding-eye 51 which embraces the separating device 43, thus supporting it in the vertical direction but permitting substantially longitudinal movement thereof through the guiding-eye 51. The elevation of the separating device 43 is thus controlled by the hand-wheel 46 through the shaft 45, the gear wheel 47, the rack/50, and the guiding-eye 51.

Journalled in the carriage 5 is a crossshaft 52, having keyed thereto an operating handle 53. Also rigidly connected to the cross-shaft 52 is a link 54 having at its outer extremity an eye 55. Passing through the eye 55 is a cross-pin 56 to which are connected vertically extending bracing members 57 and 58respectvely, for a purpose to be presently described. Connected to the frame 5 are guiding straps 59 and 60'for the bracing members 57 and 58, respectively. Operation lof the handle 53 causes rotation of theshaft 52 and consequently of the vlink 54 and, through the eye 55 and the cross-pin 56, up or down movement' of the bracing members 57 and 58, depending upon the direction of operation of the handle 53.

J ournalled in the carriage 5 is a crossshaft 61 to which is keyed a hand-wheel 462. Also keyed to the cross-shaft 61'is a gear Wheel 63. Connected with the shaft 6,1 and co-operatin'g with the gear wheel 63 is a guiding strap 64. Connected.' to the carriag'e5 at its extremity is a. U shaped `pivot member 65 to which is pivoted a. platform 66. yPivoted to the platform 66 at 67 is a curved rack 68 passing through the guiding Ystrap 64andmeshing with the gear-wheel 63, Rotation of the hand-wheel 62 causes rotation of theshaft 61 and the gear wheel 63, which through the curved rack l68 causes pivotal movement of the platform 66 about its .pivot 65.

VThe carriage 5 is longitudinally movable on the track 3 and the carriage 8 is longitudi-l nally movable on the carriage 5, the frame 33 -being vertically adjustable with respect to the carriage 8. On the carriage 5 and next tothe bracing members57 and 58 is a place for the reception of'a-pack or pile of sheets 69. The sheets 69, as above mentioned, may' lel rowsl of spaced holes 73 for apurp'ose Ato be presently described. The trucksmay be suchv as areadapted to be lowered a pickling` vat when loaded with sheets, as will be presently described, whereby the sheets will be immersed inthe ickling liquor. Instead of trucks, pickling games'. may be used, the two nefasta being substantial equivalents for the purposes of this description.

' As stated above, the sheets 69, if they come from the annealing `furnace, are very hot and, due to the various factors mentioned,-

diilicult to handle by manual labor. We shall now describe the manner in which such sheets may be moved fromthe pile on the carriage 5 to positions on edge` on the trucks m, 72, whereby the sheets are rendered in con- A dition for pickling.

The carriage 5 with the pile of sheets 69 thereon is moved 'toward the track 70 until as being substantially above the third row of.

2o holes 73 in Figs. 1, 2, and 3 of the drawings.)

Suitable locking means (not shown) may be provided for positively positioning the car-` riage 5 in any desired position relative to the.

track 70. v Pins 74 are placed in the last row to be placed on edge thereagainst.

The handle 53 is pulled to the left, viewing Figs. 1 and 2, so as to raise the bracing members V57 and 58 toa position such as/that 30. shown in Fig. 1, wherein the upper extremities of the braclng members areat a higher level than the. upper sheet in -the pile 69. .As abovementioned, the purpose of the separating device 43 is to separate a number of 'sheets from the top of the pile by reason of the projection of the sharp extremity 44 thereof into the edge ofthe pile. "The number of sheets which will be separated from the top of the pile by projection of the separator 43 thereinto is determined by the height of the separator with respect to the *frame 33. When the separator is relatively close to the frame` 33,-that is, near its upper position, arelatively small number of sheets will be separated from the pile as compared with the number of sheetsv which will be separated when the device 43 is in a lower position or farther removed frpm the frame 33. The

reason for this will become apparent as thev to description proceeds. Assuming now that it is desired to pro'ect the separating device 43 into the pack o sheets 69 at such a position that say four or five sheets will 'be separated from the top of the pile, the height of the separating device with respect to the frame 33 lis accordingly adjusted by means of the handwheel 46. .At such time the separating device is in a retracted position,

such as that shown in solid lines in Figs. 1 and 4. L The hand-wheel 13 is next operated to adjust the elevation of the frame 33 with respect to the carriage 8 so that the lower sur- 5 face of the extremity of the frame adjacent the pile oi sheets is in a plane just above of holes 73 to serve as supportsv for the sheets that of the top sheet. At such time the edge 44 of the separating .device 43 will be sub-4 stantla-lly in the plane of the fourth or fifth sheet from the top of the pile, due to its prevlous adjustment as above mentioned. The carriage 8 is then moved toward the pile of sheets until the edge of the separating device 43 almost touches the sheets, thev separating device still being in its retracted osition. At such time the extremity of the rame 33 75 will be just above the edge ofthe pile. The hand-wheel 39 is then operated to advance the separating device into the pile of sheets so as to separate the upper four or five sheets from the pile, as indicated in chain lines in Figure 4. The bracing members 57 and 58 prevent any of the sheets from being pushed away from the frame 33 by the advance of the separator as the opposite edge of the pile isagainst such bracing members.

Projecting downwardly from the frame 33 is a pair of ins for a purpose now to be described. fter the separating device has been advanced to separate the ytop four or live sheets from the pile, as indicated in Fig. 9o

. 4, the'entire carriage 8 with the frame 33 thereon isadvanced towardhe pile, the sepa-` rating device remaining between the sheets, until the pins 75 lie against the edges of the sheets. Then, by operation of the hand` 95 'wheel 13, the frame 33 is elevated until the near edges of the separated sheets have been raised some distance above the lower sheets in s the pile and untilthe lower extremities of the pins 75 are higher than all the sheets 10o except those `above the -separating device. At such time the pivoted platform 66 is in its lower ppsition, such as that shown in solid lines in igs. 1, 2, and 3; The operating handle 53 is then moved to the right, viewing 105v Figs. 1 and 2, far enough so that the upper l extremities of the bracmgUmembers 57 and, 58 are depressed below the level of the lowermost separated sheet. Thus any .opposition to movement of .the separated sheets in the general direction of the pivoted platform 66 is removed. The carriage 8 is then moved toward the right, viewing Figs. 1 and 2, and moves the separated sheets oii:` of the top of the pile 69 and above the pivoted plat- 115 form 66. The separated sheets are positively moved by reason of the bearing of the pins 75 against the edges thereof, the sheets being prevented from sliding upwardly along such ins by the lower surface of the frame 33. his operation is shown in solid lines in Fig. 2. i Movement of the carriage 8 continues until the separated sheetsare positioned directly above the pivoted platform 66, whereupon the separator is retracted by operation of the hand-wheel 39, the sheets thereby being allowed to drop down over the platform. The

-sheets thereby become disengaged from the frame 33 and from the separator 43, and the 130 while the platform in its carriage 8 is then retracted to its normal position preparatory to repetition of the operation just described.

The hand-wheel 62 is next operated to raise the platform 66 aboutits pivot 65, whereby the sheets slide to the right, viewing Figs. 1 and 2, until their edges abut against the pins 74 in the truck.' Pivotal movement of the platform 66 is continued until the sheets are swung up into a substantially vertical position and resting against the pins 74. Then,

holding the sheets to prevent them from falling down toward the left, pins 76 are placed in the second row of holes 7 3, whereby to insure positive support of the sheets in their upright position on the truck 72. The outer extremities of the U shaped pivot member are bent back, as shown in Fig. 3, to permit of insertion of the pins 7 6,\while'the carriage 5 and the platform 66 are in the position described. After insertion of thepins 76, the platform 66 is returned to its lower position and the carriage 5 is retracted until the axis of the member 65 lies substantially above the third row of holes 73. The carriage 5'is shown in this position in Figs. 1, 2, and 3. The parts are now in position for repetition of the operation just described, whereby a second group of four or five sheets'is positioned on edge on the truck on the opposite side of the pins76, as shown in chain lines 1n Fig. 2. Each time that a group of sheets is so positioned on the truck, two -more pins, similar to the pins 7 4 and 76, are inserted in the next row of holes so that the truck may be filled with sheets from one side to the other,

each group of four or live sheets being separated -and supported independently of the others by the upright pins in the truck.

The loaded truck 72 is then removed from its position opposite the sheet handling apparatus and an empty truck replaces it to be loaded with sheets in the same manner. The loaded truck is lowered intothe pickling vat to pickle the sheets carried thereby. When only four or five sheets are in each group on the truck, it may be possible to effectively pickle all of the sheets without further separating the sheets in each individual group, but, 41f desired, wooden'spacers maybe inserted between the respective sheets of each group so that each sheet will be substantially entirely surrounded by pickling liquor whenthe sheets are immersed therein.

The longitudinal movement of the carriage 5 on the track 3 and the longitudinal move- P ment of the carriage 8 on the carriage 5 may be effected by any suitable means, such as by electric motors geared to the axles thereof, Likewise the various operating functions which have been above described as being performed by operation of the various handwheels may be performed through suitable driving connections as by electric motors upper position is of sheets and then advancing the separator- 5 into the sheets, the separator may first be advanced and the carriage thereafter moved toward the sheets to force the separator between them. The exact adjustment ofthe Y height of the separator with respect to the frame 33 may also be varied according to the ideas of the individual operator, but the general function and operation of the apparatus is substantially as above described.

The apparatus is also useful for moving other shapes, such as plates, frames, and so forth, and is generally yuseful for handling things which can not be readily or easily handled by hand and which it is desired to change from one position to another.
