SHEET-SEPARATING MACHINE.

' Specification of Letters Patent.

Application filed May- 24, 1910. Serial. No. 563,299.

T 0 all whom it may concern:

Be it known that I, WILLIAM R. KIN-NEAR, a citizen of the United States, and resident of New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Sheet-Separating Machines, of which the following is a specification.

The present invention pertains to machines for stripping aparta pile of metallic sheets while the same are in their annealed or frozen state, and has for its purpose to provide a machine of that character embodying further improvements over a machine designed for a like purpose and for which I have pending an application for U. S. patent, bearing the Serial No. 518,196 and dated September 17, 1909.

'The characteristic of the machine aforesaid lies in that separate and independent means are provided for lifting a part of the sheet and then separating or stripping the sheet thus lifted-from the pile, and a further characteristic thereof is that presser feet are employed for holding down the a-d acent sheets during the stripping action. As distinct therefrom, thepresent machine contemplates the use of a single means for first lifting a partof the sheet and then stripping the same from the pile, and for preventing the adherence of other sheets to the sheet being stripped a reciprocating blade is employed which serves the further purpose of assisting in the stripping operation.

slightly lifting a part of the topmost sheets of the pile progressively as the sheets are separated; a means coiiperating with the suction means for positively holding to the carrier the edge of the sheet thus raised;

mechanism for oscillating the carrier to' strip off the sheets; a follower or auxiliary means for assisting in the stripping opera-' through the medium of the guides 14. Withthe carrier dis a plurality off suction det-ion and preventing the adherence of other sheets to the sheet being stripped; and a means for removing the stripped sheets clear details of construction of these parts and their manner of operation will be explained in the specification following.

In the accompanying drawings, which illustrate the machine by way of example, Figure 1 is a side elevation of a complete machine; Fig. 2 is a longitudinal sectional view of the. machine; Fig. 3 is a top plan view thereof; Fig. 4 is a front elevation of the suction or \sheet lifting carrier; F ig. 5

is a transverse sectional View through the carrienshowing one of ,the suction devices, and; Fig. 6 isa similar view showing one of the sheet gripping devices. Fig. 7 is a similar view to Fig. 2, with some of the parts moved into different positions.

Referring to the several figures more in detail and with like characters of reference indicating corresponding parts in the several Patented Nov. 25, 1913.

views shown, 1 designates the machine sup- 1 porting frame which is mounted to have vertical movement on the four screw-threaded adjusting bars 2 whereby it may be'lowered progre sively as the sheets are separated, the

means for effecting which adjustment is fully illustrated and described in my copending application above referred to, Serial No. 518,196, dated September 17, 1909; and

supported by said frame 1 is a frame superstructure 3' which provides the mounting for the operating motor 4, and which with the frame 1 forms the guideways 5 for the sheet stripper or carrier 6.

t The carrier (Sis adapted to have oscillatmg movement within the frame 1 and its ments, rocks upon the-pile of sheets to be separated, as will be hereinafter explained.

The side plates 7 are supported within the frame through the medium of the shaft 9,

lower ends said side sections 7 carry stub shafts 11 adapted to travel within the arcuate guideways of the depending arms 12 that which shaft at its opposite ends is journaled within the sliding blocks 10 that reciprocate within the guideways 5; and adjacent their form an integral part of the frame 13, which in turn is adapted to have slight vertical reciprocating movement within the frame 1 vices comprising cylinders 15 rigidly securedof the pile. In this order of reference, the

to a cross head 16 that forms an integral part of the frame 6, and connected with each Within each of the cylinders 15 is a piston 19 carried by the piston rod. 20 and the several rods 20 are mounted upon a common cross head 21, which cross head is, through the medium of suitable hangers 22 that straddle. the shaft 9, adapted to be reciprocated on the guides 23. For effecting this reciprocation of the cross head 21 and creating suction in the cylinders, each of the hangers 22 has-mounted thereon a; pair of oppositelydisposed rollers 24 that rideupon the cams 25 fixed upon the shaft 9.

Through the mechanism thus far described, the suction devices are adapted to engage with the topmost sheet of the pile .For imparting action to the dogs 26, the

shaft 27 is fitted with-a lever 28 whose outer end is connected with the rod 29 and said rod 29 carries opposed rollers 30 cotiperating with cams 31 likewise mounted on the shaft 9.. The relative position of the cams.

1 25 and 31 is so selected that when the edge of the sheet is lifted, the gripping dogs 26 are given their inward movement, permitting the jaws of the dogs to enter beneath the sheet. During the oscillating movement of the carrier 6, the dogs in that manner hold on to the sheet, thereby stripping it off the pile.

For actuating the suction devices, the shaft 9 has a pinion 32 which, through a train of gears 33, is connected with a pinion 34 that is fixed on shaft 33 of the arm 35 Ofthe frame 1. The pinion 34 derives its movement through the chain36 which in turn engages with the sprocket 37 that is carried by the shaft 38, said shaft 38 being rotated in turn through the chain andsprocket gearing 39, 40 and 41 from the -moto-r 4 (see Fig. 1:). And in order that the train of gearing 32 and 33 may accommodate itself to the oscillating movement of the carrier 6, the several sprockets composing said train of gearing are journaled within a flexible frame conslsting of a pair of pivotally mounted arms 42.

Cotiperating with the sheet stripper 6 is an auxiliary stripper or follower, which consists of a horizontally disposed blade 43 that is mounted on a carriage 43' that reciprocates in the guideways 44 of the frame 1, the operation of which blade is so timed that immediately the edge of the sheet is lifted,sa-id blade enters thereunder and as the carrier 6 performs its stripping movement. the blade 43 follows such movement, and in addition to assisting in the stripping of the sheet, said blade 43 is further serviceable in that it prevents the adherence of 7 any other sheets to the sheet being stripped.

The means for imparting movement to the blade 43 consists of' the pitman 45 which is.

connected at one end 46 to the carriage 43 and at its opposite end 47 to a crank arm 48 that is mounted on the shaft 38. For effecting the simultaneous movement of the carrier 6 with the suction device and the dogs 26, and of the blade 43 as above explained and for the correct positioning of these parts at the beginning of each stroke, the blade carrier 43 supports a pair of uprights 50, which through the medium of the rods 51 connect with the journal blocks 10 of the shaft 9. Thus when the carrier 43' advances with the blade, the slides 10,

'carrying shaft 9, from which carrier 6 is suspended, are pushed forward by the rods 51. As the stub shafts 11 at the beginning of the movement are held approximately stationary by the guide ways in the arms 12 the carrier 6 will, to begin with, rock around the stub shafts. During the continued forward movement of the shaft 9,'the stub shafts will be compelled to follow the arcuate path upward of the guide ways, until the carrier 6 ultimately takes the position shown in Fig. 7. 'It is arranged sothat the carrier 6 may rock upon the pile of sheets while performing the greater part. of its stripping. operation and thatv it be lifted from the pile at a certain portion thereof, or when it has about completed its stripping moveinent. To effect this lifting is the function of the vertically moving frame 13. For giving said frame 13 this necessary lifting movement, said frame is connected to the machine frame 1 by the toggles" 52 to which are connected the rods 53 and said rods are pivotally secured to arms 54 on the shaft 55. At 'one end, the shaft 55 carries an arm 56 that connects withv a pitman 57 which derives a shifting movement through the medium of the cam 58 that is keyed to the shaft 33. This arrangement will cause the frame 13' to be raised and the carrier 6 to be swung around its shaft 9, through the engagement of the stub shafts 11 with the guideways of the arms 12. The shaft 9 bemg at the time situated to the left (see Fig. 7) of shafts 11, the inner arc of the guideway, at its upper end will press against the shafts 11, thus raising them, and with them the plate held to the carrier 6. i

As the carrier 6'is lifted, the weight of the machine is partially sustained through the medium of clamps 52 that'are disposed to either side of the pile within the

guideways

53 and 53 and one of said clamps has a link connection 54 to a fixed stud 55 on the frame 1, and through a friction roller 56 that rides within a slot 57 of the carriage 43, said links 54' act to bring their respective clamp 52 into clamping engageweasel.

; fixed finger 60 and a movable upper finger 61. Said movable, finger 61 has a fixed arm 61 which is connected through a link 62 to a two armed lever- 63., 63. In the forward movement of the carrier 59., i. e. in the direction for engaging the stripped sheet, the arms 63 are engaged by cam projections 6 on the cross bar- 64 thus causing said fingers to close and engage the sheet. The joint between parts 2 nd 63 is then thrownslightly beyond the-dead center so as. to keep the fingers firmly locked over the plate. And

on the completion of the rearward movement of the carrier, the arms 63 engage with similar projections 65 and operate to release the gripping devices from the sheet, whereupon the sheets are permitted to fall to the Q floor or upon a suitable conveyor, whence they are transferred. The carrier 59 derives its movement through the mechanism for actuating the carrier 6 and the stripping blade 43, the means whereof consists of a rack bar 66 secured to the carrier 59, and which engages with a loosely mounted pinion 67., which pinion has inturn a likeengagement with the rackbar 68, and the rack bar 68 is secured to the carriage 43-. The two racks 66. and 68- are held in position with respect to the common pfnion 67 by means of retainingor uide rollers 69.
