PAPER-FEEDING MECHANISM.

'f Beit knownlthatr4 I, GEORGE F. Ross, a -'c1t1zen of the .United States, residing in llVeehawken- Heights, in the eounty of Hudson and State of New Jersey, have invented certain new and useful Improvements in Paper-Feeding Mechanism, of `which the following is a specification.

This invention relates to paper feeding mechanism and has for an object to provide improved mechanism" for feeding forward /the'lowerniost sheet of a pile o'f sheets and passing the same on to the receiving position of lsome otherfmechanism, as for instance acan labeling machine.

In the drawings accompanying and forminga part of'this specification, Figure .1 is a side'view of a practicable embodiment of ai form of my invention applied to a portion of a frame work of another machine indi cated in 'cross section; Fig. 2 isha top. plan view of the device illustrated'in Fig. 1 eX- vcept that in Fig. 1 a pile of sheets with a weighted follower is shown in osition .and in Fig. 2` the sheet receptac e is shown empty; 'Fig'. 3 "is a longitudinal section of i. the devicei Fig. 4 is a perspective detail movement of the labeling machine.

partlydiagrammatic of the mechanism for moving thesheetengaging devices into their engaging position and for then moving them forward; Fig. 5 is a side view of thefsame portions of the mechanism.

This improvement although useful in many situations is particularly designed for employment in connection with a can labelingimachine.

My present improvement embodies mechanism for accurately feeding forward the labels one at a' time from the lower side of a pile in timedrelation with the applylirlig iframe work of lLhe mechanism with which the feeding mechanism will coperate is illustrated in section at 7. Although this present mechanism embodies a complete and operative organization'in and by itself, yet

.it will in most instances be used in connection' with some other mechanism which will perform work upon thesheets which are fed forward from it. A receptacle is illustrated at for a pile ofjsheets 9 which are held in position in vthe receptacle by a weighted follower 10.' Rests 11, 11 are provided for the side edges of the pile of sheets. A rest 13 is provided for the rear end. rlhrongh the center there is provided a rest 14 which sheet yis moved forward.

On each side of the center member 111 there is provided a forwarding device 17. Each of the forwarding devices 17 is supported by a pair of links 18, 18, which are pivoted to it at its front and its rear ends respectively. The links 18 are pivoted to a frame work 19. which is supported below the receptacle. for longitudinal movement. The hmgitudinal movement of the frame is effected by means of a cam 20 which engages a roll 21 carried by alever 22 pivoted on the receptacle frame at The roll is held in engagement with the cam by means of an extension spring 23. The lever 22 is connected by means of a pitman 24 with the sliding frame 19 for reciprocating this. The shaft 25 which carries the cam 2O will means as for instance the pulley 26 which I will be belted up to some convenient portion of the fed mechanism.

I have found in practice that a suitable cont-acting surface for the forwarding devices 17 may be provided by emery paper 27 carefully applied.

The normal' position of the links 18 and of the forwarding devices 17 is illustrated in Figs. 3 and 5. In this position the contacting surface 27 is below the surface of the lowermost sheet of the pile. Upon rotation of the shaft 25 the cam 2O will move in the vdirection of the arrow and press the lever 22 and pitman 24 forward thereby drawing' The forwarding members 17 are during the first port-ion of the movement of the frame 19 held from for the frame 19 forward.

ward movement by means' of lugs 28 engaging vspring pressed detents 29. The toggle ico actionof the links 1S will, owing to the fact that the frame 19-is constrained Ato move in a horizontal plane and. that the forwarding members '17 are held fi'om forward movement, cause them to assume a -vertical position and thereby raise the forwarding members until ,their contacting facesA firmly engage the lowermost sheet of the pile. Upon a sullicient elevation of the forwarding members to engage the lowermost sheet the lug 28 will have moved outof engagement with the detent 29. At tliis position the links will engage the back stop 46. The weight of the pile of sheets and the follower will then tend to hold. the partsin the elevated position and further rotation of the shaft 25 and further advance of the frame 19 willv move the forwarding devices 17 forward and will move the lowermost sheet into a position to be .engaged by the first feed rollers 30. 'The tension of the feed rollers will be adjusted by a suitable adjusting device 31 and compression spring 32. .VVhe'n the cam Q0 assumes such position that the spring 23 will inaugurate the return. movement of the frame 1S), the weight of the paper and the follower will depress the'forwarding devices which will be" drawn idly back to initial position. The chamfered end of the spring pressed detent 29 will permit t-he detent to be depressed sulliciently to. permit the return movement without effecting an elevation of the forwarding de'- vices. rl`he delivery opening from the receptacle S is controlled b y the slide l-l adjustably held in position by links 15 and set screws 46.' 4 Having thus described my invention, I claim: ,A
