B, B, are two transverse shafts running in prop'er'bearings on the frame A, 'and having hungupon them pulleys C, two pulleys` on `each shaft; said pulleys being a suitable `distance apart. D, D, are gut bands or cords which pass around the pulleys` C,

the two cords being parallel with each'.

other, as shown in Fig. 1. Each cordhas uponit a series of collars (a) which as they passl around the pulleys fit in recesses cutl in the peripheries of the pulleys, as shownmore particularly in Fig.` 2. ends ofl the cords D, D, are connected 0r at.- tached by `screws (c) which work, or are litted in metallicsockets E, in which the bearings .of the finger shafts F, are formed.

The endsof the cords passing in the metallic l' .sockets at opposite sides, see Figs. 1 and 3.

The socketsE, also fit in recesses (79)"in the peripheries of the pulleys C, as the sockets pass around them, shown clearly in Fig-3.

The finger shafts F, are formed of two d parts, or ratherV of two shafts (e) (f) one 'r being within the other, the outer shaft (e) 3. of course being hollow or tubular, see Fig. .6." To the outer shaft (e) is secured a series lof plates and also tothe inner shaft oneY set of plates being directly `over the l other, their ends being in contact and forming lingers (g) shown in Figs. 1, 3 and 6. The ends of the plates are kept together by a l, p spring (h) which passes around twoarms l r i l l which are secured oneto each shaft 4mind. "My inventionfconsists" in a* peculiar Y A and one end of the spring (71,) being secured l by `a pin (7c) to the end of one arm and the l opposite end of the' spring to the other arm, f see Fig. 3, `and dotted lines in Figs. 1 and V 6. To theend of each of the arms (i) (j) l there is a friction roller (Z) the roller on the outer arm z') lworking on guides Io-r ways y `Gr`, Gr', .a guide or way being secured on the inner surface of each sidel of theframe A, see Figs. 1, 2 and 3. There are two iinger shafts attached to the cordsD, D', and each shaft is provided with the arms a pair of arms working at each side of the (e)`f(`f), the two arms being side by side frame A, as shown in Fig. 1'.l At the ends of the finger shafts opposite totheends to .vhichthe arms (i)` (j) are attached are secured arms at their outer ends.. see Fig. f1, which run on ways H, H 'secured a short distance from the sides ofthe frame A, bv rods (o),

The f5 (m)f(m) one to each,l finger y shaft;` said arms having friction rollers ways H, H, have semicircular recesses (72) in them as shown clearly by the dot-ted lines in Fig. 3. The front ends also of the guides or ways G, G', are curvedl in a peculiar manner with considerable sweep `as shown clearly in Fig. 3, and by the dot-ted lines in Fig. 2. On the ends of the finger shaft-s and adjoining the arms (m) there are` grooved hubs (g), one on each shaft, said hubs fitting over the ways H, H, see Fig. l.

Between the two gut bands or cords D, D, there are placed two boxes or receptacles I, I, said boxes or receptacles being secured permanently to the frame A, in any proper manner. Over the boxes I, I, there are two shafts J, J', one over each box. These shafts work in suitable bearings (7) on the upper part of the frame A, see Figs. l, 2 and 3. To one of the shafts J, there is secured arms or plates (s) (s) having a rod (s') connected to their ends. To the other shaft J', there is attached a frame K, having horizontal elastic slats or bars (s2) see Figs. l and 3, the frame being attached to the shaft by pivots (t) which pass through vertical arms attached to the frame and through horizontal arms (o) projecting from the shaft, see more particularly Figs. l and 3. Each shaft J, J', has a spiral spring L, around it and the shafts are pro-vided with arms M, at one end, said arms having friction rollers (w) at their ends, against which cams N, O, at one end of a shaft P, work, see Fig. l. TheA shaft P, is connected by gear wheels Q, Q, to one of the shafts B, on which two of the' pulleys C, are hung, see Fig. l. v

On one side of the frame A, and at its upper part there is secured a small bar and a slnall bar (e) is also secured to one of the ways H, both of these bars are shown in Fig. l, one bar (y) is shown in Fig. 2.

side of the frame.

At one end of the frame A, and adjoining the front ends of the guides or ways G, G', there are vertical guide plates R, B, see Figs. l, 2, 3 and 4, one secured at each Between these guide plates are placed two stocks S, S', the ends of which are fitted and work freely in grooves in the plates. The stocks are placed one directly over the other as shown in Figs. 3 and 4. Directly back of the upper stock S, there is a shaft T, see Figs. l, Q and 3, running in suitable bearings (a') on the frame A. This shaft is provided with two arms (5') the outer ends of which-are att-ached by pivots (0') to arms (d') (o), an arm (cl') being attached by a pivot to each end of the stock S, see Figs. 1 and 2, and dot-ted lines in Fig. 3. U, is a shaft directly back of the lower stock S', and the stock S', is attached to the shaft U, by arms (e') (6') precisely similar to the attachment of the upper stock S, to the upper shaft T. At one end of the upper shaft T, there is an larm (g') the outer end of which is secured by a pivot (L') to a rod or bar V, having a friction roller (7) at its out-er end'against which a cam W, on the shaft P, works, see Fig. l. At one end of t-he lower stock S", and at the side of the frame A, opposite to the side at which the arm (g') on the upper shaft T, is secured, there is attached an arm (7") the outer end of which is secured by a pivot (c') to a rod or bar X, having a friction roller (Z') at its outer end against which a cam Y, on the shaft P, works, see Figs. l and 2.

The stocks S, S', are of rectangular form, I

and on the inner faces or surfaces of each stock there are secured three nippers Z, Z, Z, see Figs. l, 2, 3, 4 and 5, three nippers are shown in the drawings but more or less may be used. The upper parts of the nippers are fitted in sockets (m') secured to the upper parts of the stock,.the nippers being fitted so as to move freely within said sockets and prevented from dropping from the sockets by pins (n') which are att-ached to the nippers and rest in recesses in the top o-f the sockets as shown Clearly in Figs. l, 4 and 5. A spring (0') attached to the stock bears on the upper surface of each nippel',

shown in Figs. 3 and 5. The upper ends of the jaws are riveted together or the jaws may be cut from a solid piece of metal.

Through the recesses (gx) of the nippers on each stock S, S', a bar A', runs saidbar having a blade or flat strip of metal (8x) secured to its under surface as shown in Figs. 3, 4 and 5. Each bar A', is secured to itsstock by arms (25') (t') which are attached to the bar and the stock by pivots (u') (u') the arlns of each stock being parallel with each other as shown in Fig. 4. To the upper bar A', there is secured at one end a horizontal arm (o') which projects beyond the side of the frame A, and is provided at its outer end with a friction roller (w') and at its inner end with a roller (l1). At the opposite end of t-he bar a friction roller (70') is attached see Fig. 4. The

lower bar A', is also provided with an arm (a2) is secured.

J'", and upon each shaft there are two rollers (u2) (u2) fitting loosely thereon, see Figs. l, 2, 3 and 5, and also two eccentrics (112) (o2) having hooks (to2) (102) attached to them, one to each. There is also attached to each shaft K',r` at about itscenter a Y Weight L". Y l l r j side ofeach shaft K', there is secured a small stud or, projection (y2) to the outer end of which a rod (22)is secured bya pivot (l) ,shown by dotted lines in Fig.` 5, the opposite end of this `rod being attached bya'pivot (2) to a stud or small "upright projection (3)` `permanently attached to` each platform.

`see Figs. 2, 3 and 5. .Y 1

` :Underneath each stock S, S', there is a small spring ""see Figs. 3 and 5. And upon each of the shafts T, U, directly back of the stock spiralsprings (9) (9) are placed.

Operation: I will first `proceed to show the operation of the fly, by which the sheets of paper `are conveyed from the nippers to the form and when printed deposited in the boxes or receptacles. The shaft B, to which one ofthe gear wheels Q is attached is the driving shaft. Motion being given this shaft, the gut bands or cords D, D, of course rotate around the pulleys C, on .the shafts B, B, and are prevented from slipping thereon in consequence of the'collars (a) on the cords fitting in the recesses `in the pripheries of the pulleys. The ends of ,the cords are firmly secured in the sockets E by thescrews (c) (c) which sockets also fitfin recesses (Z2) as they pass'around the pulleys. IThe finger shafts F, which have grooved hubs (g) at one end of the shafts are stock and` oneat each end. The lower ends running on the ways H, and the friction' rollers (Z) on the outer arms (Z) at the opposite ends of the finger shafts running upon the ways or guides G, G', see Fig. l, keeping the finger bars steady while moving over the ways. The friction roller (Z) that runs upon lthe guide or way G, follows of course the curve at the outer end of said guide or way and as the friction roller as- .cends the curve the finger shaft is gradually turned in its bearings and the friction roller (n) at the end of the arm at the opposite end of the finger shaft is consequently depressed and catches against the curved end of the way H, and fall into the recess (p) and as the nger shaft still moves forward it is turned about one half of a revolution the roller (Z) on the arm (i) at the opposite end of the shaft vfollowing the guide G, which is so curved as shown in Fig. 3, so as to present the fingers properly to the edge of the sheet of paper shown in red and which is raised up by the nippers Z. W'hen the fingers are in this position, the roller (Z) attached to the inner arm (j) comes in contact with the projection (y2) and the arm (j) is kept nearly in a ori- `zontal position while the roller (Z) on the outer arm (i) follows the curve of the guide which projects nearly horizontally a short distance forming a jog,. the vtwo arms (2') (j) are consequently expanded and the fingers a're opened and whenthe roller has passed o the projection (7'2) the fingers grasp the edge of the sheet presented to them by the nippers Z, in consequence of the spring (L) and carry it downward around the front pulleys C, and upward around the back pulleys C, on the driving shaft B, the sheet of paper during its travel vfrom the front to the back pulleys underneath or during any other portion of its travel receiving the impression of the form, which may be placed upon a cylinder, or flat bed arranged in any proper way. The sheet of paper after passing upward around the backV pulleys C, passes along toward the -front of the machine till the roller (Z) on the inner arm at the end of the finger shaft comes in contact with the small bar (s) attached to one of the ways H, said bar causes the roller (Z) to pass underneath it and consequently depresses the inner arm (j) and the fingers are opened. At this point the prominent part of the cam` N, at the end of the shaft P, passes the friction roller (fw) at the end of the arm M, attached to the shaft J', and the arm M, being freed from the action of the cam the spiral spring L, is ermitted to throw down the frame K, whic being directly over the box or receptacle I, resses the sheet snugly therein, the sheet 1being freed 'from 'the lingers (g) when directly over said box. The lframe K, is then raised to its original position by the action of the cam N, and the finger shaft still moving as before to act upon a succeeding sheet.

In the drawings two finger shafts F, F, are represented and two boxes or receptacles I, I, and also two nipper stocks S, S', but the operation of both devices is'precisely similar one being a duplicate of the other, with the exception that the guide or way G', passes downward directly from its curve at its outer end, see dotted lines Fig. 2, so as to enable the fingers on the other shaft, to present themselves properly to the sheetheld by the nippers on the lower stock S.

I will now -proceed to show the operation of the nippers Z, confining myself to the operation ofl those on one stock only, as one is merely a duplicate ofthe other. The stock S, has an up andy down motion given it the upward motion is obtained by a cam W, the prominent parts of which act against the friction roller at the end of the bar or rod V, and throws the shaft T, backward the arms (ZJ') (72') on the said shaft elevating the stock, when the friction roller is freed from the cam ll, in consequence of the prominent part of the cam passing it -the stock descends by its own gravity assisted by the spiral spring (9) on the shaft T. Suppose the stock S, to be elevated as shown in Fig. 8, the nippers Z, then hold a sheet of paper so as to be grasped bythe fingers (g) and while in this position the curved or bent arm (10) on one of the pulleys 0,'

acts against the roller (m2) at the outer end of the lever H', raising the outer end of the lever and causing the beveled or under side of lthe projection (n3) at the inner end of said lever to bear against the roller attached to the bar A', and force said bar in the direction indicated by the arrow, see Fig. 4, the blades (sx) of the bar of course descends into the V shaped recess (74') at the lower end of the jaws (p') (p') and owing to the curvilinear motion of the arms (t') (Z') and forces the jaws apart and the sheet of paper therefrom just after its edge is grasped by the fingers the lower edge of the blade descending a trifle below the edges of the jaws so 'as to clean them from any fibrous portions of the sheet which by chance may stick to them, see blue lines in Fig. 5, the lower edge of the blade (sx) loeing shown below the jaws by dotted linesl The sheet of paper ifs now withdrawn from underneath the stocks the stock meanwhile descending by its own gravity and the action of the spring (9), the roller (i') being relieved from the action of the cam W. As the stock S, descends the roller (l1) on the bar A', comes in contact with the inclined ,surface of the projection (f3) and the bar A', -is then -moved 1n 'a vreverse'direction, as indicated by the red arrow Fig. 4. The bar A', and blade (8") is consequently j movedupward, acertain distance and the I ifa-ve (rf I (mirare pressed ree the prer- "most sheet `jof .`paper`,"the -pileor sheets` of p sented to the fingers at the same time,

The` small spring `(8) underneath the stock merely ears fupon therising` sheet ,and

"keeps its centerbent downward sobasto insure its outeredge bending upward.

" The nippers cannot grasp more than one sheet ata" time, because"` the jaws (p) (p') f "are'distended more orless to suit the thickness of the paper used. If thin sheetsare `used the jaws when pressing upon thepaperl are not much distended, and consequently a fold orl ridgefonitheI upper sheet only will be formed *between them.. If

thick paper `is used the jaws are distended to a greater extent so asto insure the forming of a ridge or fold between themff The jaws are distended tofa greater or less eX- tent by graduatingthe movement of the bar l Af, which is erected by `adjusting the pro- The jection (f3) so that it may act moreor less agamstsaid bar. j

To prevent two sheets from being preandals-o to prevent the second sheet from being drawn off the pile of paper by the top sheet when it is withdrawn by the fingers, j in consequence of their sticking together by 1 moisture or other causes, the separating deon thesame shaft and the hooks and rollers remain in thisposition tillthe sheet of paper is elevated by the nippers Z, a certain distancewhen the upper inclined surfaces Vof .the` projections (6) `at .the lower `end of 4the bars (5)"bear against the rollers yateach side of the platform I', and force the platform I', and feed board J outward as indicated by arrow (1) see Fig. 5, and the shaftf K', is turned simultaneously with lthe moving of the platform by means of the 3rod (e2) sothat the points of the hooks pass through theupper sheet which is grasped by the nippers and consequently does not .fmove outwardwith theother sheets on the feed" board, the hooks being somewhat inclined merely make perforations without` jtearing or` disfiguring in any manner the sheet through `which they` pass. points of thehooks have passed through the After the upper sheet the outer edgesof Ithe hooks passing through the second sheet as it moves with the platform and in the same direction Awith the hooks. The second sheet of paper therefore and those underneath it have the weight of theshaft K', with its rollers (wz) and weight L', upon it for the hooks in turning, elevate the shaft K', with its appendages, see blue lines Fig. 5. The platform 1', after the upper inclined surfaces of the projections have passed the rollers, (7) moves inward -in consequence `of "the spring (4) as indicated byarrows (2),`

see Fig.` 5, `and the shaft K, is then" of courseturnedin a reverse direction and also the hooksl (to2) ((10.2) which pass out'from the perforations their points` made in the uppermost sheet yleaving the` rollers upon the second sheet and the weight of theshaft K', just previous to the withdrawal of the raised sheet by the fingers (g) "of the fly.

The red dotted lines in Fig. 5, show the last position of the hooks. The hooks therefore pass 4through the uppermost sheet leav- .Y

ing it free to be fully raised by the nippers and at t-he same time prevent the displacement of the sheets underneath by bearing upon them till the points of the hooks have been withdrawn from the upperv sheet when the rollers (u2) rest upon them instead. It

will be seen therefore that the upper sheet is left free to be acted upon by the nippers, while the under sheets are kept properly in place at all times, either by the pressure of the hooks or the rollers upon them.

The ball L', is attached t0 the shaft for the purpose of giving it additional weight. The platform and hooks are brought in the position as shown in black Fig. 5, by the under inclined surface of the projection (6) during the downward motion of the stocks.

Two sheets cannot be presented to the fingers (g) at the same time in consequence of the nippers grasping them, this cannot be done as has been previously explained. The :1

paper from the feedl boards to the form to be printed and also from the form when printed to the proper boxes or receptacles, -by means of the fingers (g) attached to the tube and shaft F, which is secured to endllless bands or cords D, D, which are proi vided with collars, or teeth, to prevent them separating device obviates the diiiiculty which would often occur by the sheets sticking together in consequence of their moist state or other causes. The second sheet, if the separator were not used, would often adhere to the first or upper sheet grasped by the nippers and follow it although not actually held by the nippers and the same difficulty would be experienced as if the :be equivalent to the above named parts,-

nippers really grasped it.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 1. Lifting or picking up the sheets of paper from the feed boards or piles of paper to be printed by means of nippers, pincers, or tweezers Z, constructed as herein shown or in an equivalent way, and operated by any suitable mechanism so that the jaws of said nippers may when slightly open press upon the sheets of paper in such a manner (to2) or by pins, or points, so constructed and operated as to answer the same purpose,

and rollers (u2) (u2) attached to a shaft K',

or other suitable fixtures, and in connection with said hooks, and rollers, by means of a reciprocating motion of the plat-form I feed board and pile of paper; the said hooks, pins, or points acting conjointly with the said movable r platform substantially as herein shown and described.

3. I claim conveying .the raised sheets of slipping, in passing around suitable pulleys or by means of other fixtures which would when they are used in connection with a vibrating or movable frame K, or its equivalent, for properly adjusting the printed sheets in the boxes or receptacles I, when released from the fingers, as set forth in the body of the specification.
