PAPER-FEEDING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 492,218, dated February 21, 1893.

Application filed February 16 1892. Serial No. 421,898. (No model.)

To 60% whom it may concern:

Be it known that I, NICHOLAS LUX, of Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Paper-Feeding Attachment, of which the following is a full, clear, and exact description.

The invention relates to paper feeding attachments for printing presses, ruling machines, 85c.

The object of the invention is to provide a new and improved paper-feeding attachment, which is simple and durable in construction, and arranged to automatically and accurately deliver a sheet of paper to the machine.

The invention consists of a frame provided with legs, and cams mounted to revolve on the said frame and adapted to lift the said legs off the paper, at the same time pushing of a set screw or other device.

the top sheet forward.

The invention also consists of certain parts and details and combinations of the same, which will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a planview of theimprovement; Fig. 2 is a sectional side elevation of the same, on the line 2-2 of Fig. 1; Fig. 3 is a similar view of the same in a diiferent position. Fig. 4 is a detailed sectional elevation of one of the adjustable keepers and its supporting hanger or leg, hereinafter referred to.

The improved paper feeding attachment is provided with a frameA,'formed with the two side bars B, B,- connected with each other at or near the middle by a yoke 0 formed, on its top, with pins '0 for supporting weights to increase or diminish the weight of the said frame A. The side bars B, B, are connected with each other, near their rear ends, by a transversely extending bar D, supporting two or more legs E, and similar legs E are arranged in front of the yoke C, the said legs being mounted on a cross bar or red D also attached to the side bars B, B. Each of the legs E or E is provided with a keeper E fastened to the'respective rod D or D by means In the keeper E is held vertically adjustable a rod E fastened in place on the keeper by a set screw,

as is plainly indicated in the drawings. 0n the lower end of the rod E is pivoted a foot E lined, at its lower end, with rubber or other material E adapted to rest on the ream of paper F, supported on the feed table G of the machine on which the attachmentis applied. The movement of the upper end of the foot E toward the rod E is limited bya set screw E and a spring E presses said upper end outwardly.

Between the cross bar D and the yoke O is arranged a transversely extending shaft II, journaled at its ends in the bars B of the main frame A. On this shaft H are secured by set screws or other means, two or more cam arms I, each formed at its lowerend with a lining I made of rubber or other suitable material. The cam arms I are somewhat longer than the rear legs E, so that when the cam arms I move in contact with the top sheet of the ream of paper F, then the rear legs E are lifted olf the paper, as is plainly shown in Fig. 2.

On the front end of the main frame A, is arranged a transversely extending shaft; J also journaled in the side bars 13, and carrying two or more cams K, preferably made in the shape of disks, having part of their peripheries formed with a flat surface K, as is plainly shown in Figs. 2 and 3. When the fiat surface K is directly above the top sheet of the ream of paper F, then the front legs E rest on the top sheet of the paper, but when the shaft J turns so that the peripheries of the disks engage the top sheet of the paper, then the front legs E are raised off the paper, as is plainly illustrated in Fig. 3.

On the shaft H is secured a sprocket wheel L, over which passes a sprocket chain L also passing over a sprocket wheel L on the shaft J, and also passing over a sprocket wheel L secured on a shaft N extending transversely and mounted to turn in suitable bearings in the side bars B of the main frame A directly below the yoke C. Thus, when the shaft N is rotated, the sprocket wheel L imparts a traveling motion to the sprocket chain L. which latterthus simultaneously revolves the sprocket wheels L and L so that the shafts H and J are set in motion and the cam arms I and cams K are actuated to lift the legs E and E off the paper and to push the top sheet of the ream of paper F forward, as hereinafter more fully described.

On one end of the shaft N, is secured a sprocket wheel 0 over which passes a sprocket chain 0, also passing over a sprocket wheel 0 secured on a shaft P, mounted to turn in suitable bearings secured to the rear end of the table G. The shaft P is connected with suitable machinery for imparting a rotary motion to the said shaft, so that the feeding attachment is set in motion to feed the sheets of paper to the machine at the proper time.

On the shaft P is hung a frame Q' formed with side arms engaging the shaft N, sothat the entire feeding attachment can be swung off the ream of paperF whenever desired, the said frame Q then assuminga vertical position, asindicated in dotted lines in Fig. 2.

In front of the ream of paperFis arranged an inclined feed board R secured at its lower end on the feed table G, but extending, at its upper end, close to the rollers Sand S, journaled insuitable bearings on the feed table G. The board R serves to guide the sheet of paper pushed off the ream F between the said rollers'S and S, which latter feed the sheet forward onto the straightening plateT pivotallyconnected, at one side, with the links U and U ,of which the linkU is formed with an extension connected with a rod V for placing the said. plateTin a normal position with the sheet of paper resting on top of the same, so as to pushthe sheetagainst the usual stops-to guidethe' sheetin the proper direction to be takenup by the pressing or ruling machine.

The operation. is as follows:When the frameAis over the ream of paper F, the front and rear legs E and E rest on the uppermost sheet of paper, the cam arms I then being off the paper. Now, when the shaft P is set in motion, the shafts H and J are rotated,so that the camarmsI swing downward, their linings I engaging the top sheet, thus lifting the rear part of the' frame A upward, whereby the rear legsE are raised off the ream of paper to permit the. cam arms Ito push the rear end of the top sheet forward. It is understood that at thistime the. flat surfaces K of the cams K are directly opposite the-top sheet of themper F, so that the front legs-E really form the fulcrum forthe frameAto swing on. v The top sheet of paper is caused by the arms-I to assume, between the latter and the-front legs E, a curvedposition, as indicated in Fig. 2. At this time the motion of the shaftJ brings the peripheries of the cams K into contact with the top sheet of paper near its front end, so thatthefront legs E are lifted off the top sheet of paper, and at the same time the cam ELIIDSII still push forward on the top sheet, and alsothecams K act on the top sheet to move the same forward, see Fig. 3. At this time the rear legs E rest on the next'following sheet of paper. The movement of the cams K causes the top sheet to be fed forward on the ream of paper, the sheet passing upon the board R and from the latter between the feed rolls S and S, to finally be delivered by said rolls on the plate T for straightening and delivering of the paper to the press or ruling machine. The above described operation is then again repeated, that is, the cam arms I again engage the top sheet of paper on the ream F lifting the rear legs off and pushing ment is out of the way and does not hinder the operator from feeding by hand in the usual I manner.

The weight of the frameA is increased diminished by placing additional weightson the pins 0, as previously mentioned. This is necessary according to the nature and size of the paper to be fed to the printing or ruling machine.
