Be it known that LLE'VI ORSER, of -Galves; ton, in the county of Galveston and State off Texas, have invented new and useful Im'-A `'provements in Feeders for Printing-Presses, of which the following is a full, clear, and eX- which'lie yon the sheet of paper to be lifted,

fprojectingover its edges and turning and vmoving up with it, to deliver. a blast of air .against the sheet of paper, while it is being fturned and lifted, operatingin connection with brushes to prevent more than one sheet lbeing lifted at a time.

. The construction and operation of the several parts hitherto enumerated will now be described. A

Reference is to be had to the accompanying drawings formingapart of this specification, in which similar figures and letters of reference indicate corresponding parts in .all the views.

Fig. 16 is a vertical section of the holder D with its connecting tube broken showing groove 16; Fig. 18 a plan view of one of the sleeves 25 with retaining plates and brushes; Fig. 19 a side elevation of the gage block 19.

Referring to the drawings, 1, indicates the frame work in which the feeder mechanism is mounted, Figs. 1 and 2. board are secured blocks 3 having upright bolts 4 carrying thumb screws 5, Fig. 10.

6 indicates a horizontal rod with holes through its ends adapted to slip over the bolts 4.

7 are clamp blocks with holes bored through them to slip over the bolts 4, above the horizontal rod 6, the blocks 3 and 7 being grooved in the center to clasp the horizontal rod 6 which has, near its center, two arms 8 to the upper ends of which is secured a guard bar 9 being rounded on top and fiat underneath. The horizontal rod 6 carries sleeves 10 adapted to slide freely thereon their under sides resting on the feed board 2.V The front side extends upward forming retaining plates 11, against which the front side of the pile of -paper rests; pins 12 provided with thumb screws 13 project from the upper sides of the sleeves 10, and brushes 14 having horizontal slotted arms 15, slip over the pins 12, and are held by the thumb screws 13, the slotted arms 15 permitting the brushes 14 to be adjusted to any desired position, Fig. 1. When the thumb screws 5 are loose the sleeves 10 may be moved freely, along horizontal rod 6 to accommodate any size of paper, but when the thumb screws 5, are set, they operate to press the sleeves 10 down against the feed board 2 holding them iirmlyin position. The guard bar 9 serves to protect the paper from being injured by the brushes or retaining plates while it is being carried forward.

16 indicates a groove cut in the feed board 2 Figs. 1 and 17, having metal strips 17 let into the feed board, their inner edges forming a slot 18; a plate 20, having bolts 21 projecting upward through the slot 18 into a gage block 19 (Figs. 1 and 19,) is adapted to move in the groove 16. From the center of plate 20is a bolt 22 projecting upward through the Upon the feed slot 18 and through the gage block 19 and is provided with a thumb screw 23.

Secured to the gage block is a horizontal rod 24 having sleeves 25 adapted to slide thereon, Fig. 1. The under sides of the sleeves 25 rest on the feed board 2, and carry retaining plates 26 adapted to rest against the pile of paper behind said sleeves at the sides, and also carry pins 27 having thumb screws 23, Fig. 18, and brushes 29 carried by arms 30 having bent slotted portions 31 are adapted to slip over the pins 27, and be held by thumb screws 28, the slotted portions permitting the brushes to be adjusted to any desired position. The gage block is adapted to move freely in the slot 18 which extends from the rear side of the feed board nearly to the front. The sleeves 25 are adapted to move freely on the horizontal rod 24 sliding over the surface of the feed board but when the thumb screw 23 is set it holds the gage block firm and operates to press the sleeves 25 against the feed board, holding them in whatever position they may stand. Grooves 18E, the same as the groove 18, extend from the sides of the feed board, nearly to the center, and have gage blocks 19, adapted to slide therein similar to the gage blocks 19, except that instead of the horizontal rod 24 they carry retaining plates 32, on their forward ends, adapted to rest against the sides of the pile of paper. By this construction the retaining plates can be quickly adjusted to accommodate any size of paper, Fig. 1.

D, indicates an improved form of holder for holding the paper while being transferred, and consists of, a flexible tube 33, Fig. 16, having an enlarged part 34 by which it may be firmly held by clamping plates 8l, and having a flat disk 36 even with its lower end, flaring up toward the center, and being joined to the tube 33, a little above the end. Small holes 37, made through the tube a little above its end, furnish comrnmunication between the space under the disk 36, and the interior ofthe tube 33. By this construction the tendency of the paper to adhere to the end of the tube so close as to relieve the vacuum pressure between the disk 36 and the sheet of paper, is avoided; the full force of the vacuum pressure being continuously exerted between the disk and the sheet of paper so that the hold upon the sheet is much stronger and more certain. The end of the tube 33 resting against the sheet prevents it from cupping. Instead of the holes 37 the ends of the tubes 33 may be notched.

Suspended from a rock shaft 38, in the top of the lnachine is a horizontally swinging frame A, consisting of two downward projecting bent-arms 40, connectedtogether by cross bar 41, and truss 42, and carrying at their lower ends a horizontal bar 43 whose ends bend downward, terminating in two downward projecting slotted arms 44, Figs. 1 and 9. `The rock-shaft 38 being pivoted in the frame 1 and the frame A, secured rigidly IOO tog

`of the movement.

theretois adapted to swing back and' forth like a pendulum, Figs. 4and 5. On the inside of .the truss 42 is an arm 45 carrying a friction-roller 46, which is adapted to operate in connection with a cam 47, mounted on the shaft 48, to swing the frame A, back, which, on being released by theV cam, swings forward by its own weight being accelerated as much as may be necessary by springs 49, attached .to a brace 50 carried by the lever A; the forward endsof the springs are fastened to arms 51, projecting from the front side of the frame 1. The'frame A is provided with braces 52,

so disposed as to give it the required strength and rigidity, and permit it to swing to-its for ward limit by its own weight and without striking the shaft 48. The cross bar 4l carries a sleeve 53, and the horizontal bar 43 carries in its center a sleeve 54.

B, indicates a frame which reciprocates vertically and swingsA horizontally, and consists of a rod 56, a bent slotted portion 57 having shoulder'58, Figs. 4 and 5. Rod 59 carries at its lower end a sleeve 60 held by set screw 61, Figs. 1 and 9. Secured to the sleeve 60, is a horizontal-bar 62, having downward projecting portions 63, secured to which arecross ward projecting portions 63 carry at their lower ends pins 67. 1 The shoulder 58, serves' as an off-set to bring the rod 59 in the center A brace 68 secured to the horizontal bar 62, thence bolted to a sleeve 69 held by set screw 70 to the rod 59, serves to hold the horizontal bar rigid,Figs. 1- and 9.

The frame B is adapted to move freely through sleeves 53 and 54, Figs. 1, 4 and 5, and its pins to move freely in the slots 71, Figs. 1 and 9. By this construction it will be seen, that the frame B will swing horizontally with the horizontally swinging frame A, and be, Y at the same time, free to reciprocate vertically, beingl raised vertically by a cam 72 which'moves in the slotted portion 57, Figs. 1 and 5, and

`bears against the friction roller 73 on the le# ver 74, and is drawn down by its own weight;

Reacting springs 75 attached tothe sleeves,

A54 and 60, Figs. 1 and 9, serve to counterpoise so much of the weight of the frame B- as is not necessary for its proper operation. The horizontal-bar 62 carries a guide-sleeve 76, and the Vsleeve 69 carries a guide sleeve 77 Figs. l, 9, and 14.

The turner mechanism C, which operates Ain combination with the horizontally swinging and vertically reciprocating frames, will now be described.

In lifting a sheet of paper from a pile, it is necessary to first turn up the front edge so as to allow the air to enter between the sheet being lifted and the one lying next to it. For this purpose l provide the following described mechanism: A horizontal rod 78 carries sleeves 79, adjustably held thereon by thumb screws 80 said sleeves being provided with double clamping plates 8l, which carry the holders D and also the rests 82, Figs. 1, 7, and 9. Secured to the end of the horizontal rod 78 are levers 83 having slots 84 in their forward ends, in which the pins 67 are adapted to move, Figs. 1 and 9,their rear ends being pivoted on pivot pins carried by vertical bars 86 which are connected together, near their lower ends, by the horizontal rod 87, and at their upper ends by horizontal bar 88 carrying at its center a sheave-block 89 through which passes a Vertical guiderod 90, the lower end of which is adapted tomove freely in the guide sleeve 76 and the upper part in guide sleeve 77, Figs. l, 9, and 14. Near the upper end of the guide rod 90 is a collar 91, held'thereon kby set screw92. The vertical bars 86 have slots 93 in which the pins 66 are adapted to move. Braces 94, extend from the sheave-block 89 to the vertical bars 86, to give the several parts the required lrigidity and strength. By this construction it will be seen that the verticallyreciprocating frame B can move up independent of the turner C, until the guide sleeve 77 abuts against the collar 91 when the turner C will be carried up. Leather washers 95 on the vguide sleeve 7 7 serve to cushion the stroke. A

reacting spring 96, on the lower part of the vertical guide rod 90, serves lto counterpoise so much of the weight of the turner as is not necessary for its proper operation, Figs. 1

and 9. The distance that the vertically reciprocating frame rises before raising the turner may be varied by setting the vcollar 91, higher or lower on the guide rod 90.

97, indicates a buffet brace, the ends of which turn upward and are bolted to the frame 1. In the center of thebrace is a shoulder 98 through which passes a buffet screw 99 having a jam nut 100, Figs. -1 and 14. As the turner movement swings forward, the cushion 101, on the horizontal bar 43, Fig. 9, strikes against the head of the buffet screw 99,thus terminating its forward motion; the buffet screw may be set forward or back, thus varying the forward swing of the turner movement and consequently the point atwhich the paper will be delivered.v The jam-nntserves to hold the buffet screw at whatever place it may be set.

Projecting downward from the center of the buet brace 97, is an arm 102 carrying a rest V103. As the vertically reciprocating frame B is descending at thefpoint of delivering the paper the sleeve 69 comes in contact with the rest 103, thus terminating its downwardstroke, which may also be varied by changing the position of the'rest 103 on the arm 102. The rest is cut away in the center to clear the rod 59 and is facedwith leather to cushion the stroke.

. .-104 indicates a strip of leather or like sub- IOO press. Projecting downward from the frame l are buffets 105, Figs. 1 and 14, faced with leather, operating to limit the backward motion of the horizontal swinging frame A by the horizontal bar 43 striking against them.

In lifting a sheet of paper from a pile it is necessary to have jets of air impinging against its edges to act in combination with turner mechanism C, and brushes 14, to prevent more than one sheet from being lifted at a time. For this purpose an air blast is provided, consisting of a cylinder E, piston` F, and piston rod G, havinga reacting spring I-I coiled about it. A brace I attached to the frame 1, serves to hold the cylinder in position, and to hold at its upper end a guide .I through which the piston rod is adapted to move. Near the upper end of the piston rod G is a collar K, held by set screw L. The piston F has a shoulder M carrying pins N on which connecting rods O are pivoted. A lever P, carrying a friction roller Q, is pivoted at R to the frame l. The forward end of the lever P is forked so as to pass on the opposite sides of the piston rod, and carries at its ends pins S on which the upper ends of the connecting rods are pivoted. A cam T, on the shaft 48, operates, in connection with the friction roller Q, to raise the lever P,thus` forcing the piston to the top of the stroke, which, being released by the cam, is forced down by the reacting spring H, the downward stroke of the piston being stopped by the sleeve K abutting against the guide J. The length of stroke of the piston may be varied by moving the collar K. Leather washers U, on the guide J, serve to cushion the stroke. A pipe V, having flexible tubes W attached to it, serves to convey the air to tubes X having lugs Y (Fig. 7) by which they are bolted to sleeves 79 by bolts and nuts Z. The air is conveyed from the tubes X, by flexible tubes a to the nipples b, the ends of which are turned down at right angles and have small openings s, on their inner sides. Plates on the under sides of the nipples have ears c, by which they are fastenedto the clamping plates 81, by cords d, being so adjusted as that when the holders D are brought down upon the pile of paper the nipples Z1 will lie on the top sheet, their ends projecting a short distance beyond the edges of the paper. By this construction it will be seen that the nipples turn and move with the edge of the sheet of paper. The mechanism is so timed that the air blast will be continued during the time the edge of the sheet is being turned and lifted. The pipe V, projects some distance above the bottom of the cylinder E, to prevent any oil from entering it. A stop cock e serves to draw off the oil that may pass below the piston F; or an ordinary check valve may be used, which will let the oil drain 0E but prevent the air from escaping.

f, indicates a lever pivoted to an arm g, attached to the frame 1, Fig. 12. The forward end of this lever is adapted to move in aguide t', and is connected to the three way stop cock 7c by a connecting rod j, a bearing Z, attached by studs m to a cam 47, operating upon the friction roller n forces the lever up to cut olf the vacuum pressure and open communication between the tubes 33, and the atmosphere, and when released by the bearin g, falls by its own weight to turn on the vacuum pressure, at the same time, closing communication between the tubes 33 and the atmosphere. In falling the end of lever f strikes a cushion o.

Attached to the vacuum pump p, is a blow off valve, consisting of an upward projecting tube q, Fig. 13 having a seat r, inthe center of which is an opening in which a ball t is adapted to fit to make an air tight joint, Fig. 13. u is a case held in position by bolts and nuts v and having openings w, the Whole being surmounted by a hood y. lVhen the piston (not shown) descends the air, that is in the vacuum cylinder p, forces the ball up and passes out through the openings w, and the cap u serves to catch the ball and cause it to drop back upon its seat to prevent the air from entering. Any oil which may accumulate in the cylinder will be blown out with the escaping air, and will be caught by the hood y. A piece of kid or other thin leather may be used as a packing between the seat fr and the ball, the cap u serving to hold it in place; the cap may be screwed on the tube q. Instead of the blow-olf valves as shown a common check valve may be used, so arranged as to allow the air to escape but to prevent it from entering.

The lever 10G at its forward end carries bolts 107 on which are pivoted connecting rods 108, Fig. 15, the upper ends of which are pivoted on bolts 109 carried by a shoulder, 110, at the top of the piston rod 111, of the vacuum pump p, Figs. 1 and 9. By this construction the connection between the lever 106 and piston rod 111 is direct and the movement easy.

112 indicates angle-iron bars, bolted to the frame 1, Fig. 1, which extend upward to the ceiling to be thereto attached by brackets, (not shown) to hold the vmachine in position, being strengthened and braced by crossbraces 113.

The several cams, hitherto mentioned, are mounted on the shaft 48, coupled to which, by a coupling, 114, is a shaft, 115, having a clutch, 116, held by set screw 117, Fig. 2. 118, indicates a sprocket wheel in the collar of IOO IIO

which is cut a clutch adapted to engage the clutch 116. A coil spring 119 presses the sprocket wheel against the clutch, and a collar 120, held by set screw 121, serves to hold the spring in place. The sprocket wheel being loose on the shaft when turned forward will turn the shaft 48, but when turned backv ward will slip around, leaving the shaft at rest. A brace 122, bolted to the frame 1, serves to hold a horizontal bar 123, on which is pivoted a lever 124. The forward end of said lever being forked it is adapted to push the sprocket Wheel back, disengaging the clutch so that the vsprocket wheel may turn forward, leaving the shaft-at rest. The rear end of the lever 124 is pivoted to a connecting bar, 125, attached to a connecting rod, 126, which latter is held in position by supports 127 and 128, said rod being provided with a handle 129 at its forward end and to the upper end is hinged a latch 130 Fig. 3. l/Vhen the handle is drawn it operates to throw the machine out of gear, the latch dropping by 1ts own weight against the support 128, to hold it in that position. When the latch is lifted the spring 119 forces the sprocket wheel against the clutch, throwing the machine in gear and pushing the lever back. The sprocket Wheel is to be driven by an endless chain from a corresponding wheel attached to the press to be fed (not shown). The sprocket wheel118 and clutchll'maybe setat anypoint on the shaft, so that it will stand in line with the corresponding wheel on the press, the shaft being made long enough so that the sprocket wheel may be set to suit any press with which the feeder may work. The lever 124 may be pivoted at any point on the horizontal bar 123 and connecting bar 125, to suit the position of the sprocket wheel. The free end of the shaft 115 is supported by a journal box 131; the shaft 48, carries a hand wheel 132, Fig. 1, by which the machine may be turned by hand for adjustment or other purposes. The machine is provided with ample drip pans one of which (133, Figs. 1 and 9) only is shown.

When it is desirable to locate the feed board below the point of delivery of the paper, the adjustable retaining plates for the front edge of the feed board may be arranged as shown at Fig. 8, in which 6a, indicates the horizontal rod located under the feed board 2a. Secured to the sliding sleeve 10a are the retaining plates 11a, bent upward and carrying pins 12, provided with thumb screw 13a. Arms 8a, projecting forward and upward from the horizontal rod 6a, carry the guard bar 9'. Clamp blocks V3*, Fig. 6, has bolts 4f, which pass through the horizontal rod, blocks 7 a and feed board, and has thumb screw 5 which, being set, draws the horizontal bar up against the feed board'holding the retaining plates 11a firmly in position.' When the thumb screw isloose, the sleeves 1Ol may be moved to any position.

The operation of the machine is as follows: When, by the rotation of the shaft 48, the holders D are brought down upon the pile of paper, the lever n, being released by the bearing Z, drops by its own weight, operatin-g the three way stop cock la to turn on the-vacuumpressure to the holders D, causing the disks `36 to adhere iirmly to the top sheet; any air that may leak in between the disk and the sheet of paper is rapidly drawn through the holes 37 into the tube 33, thus maintaining the pressure; simultaneously the cam T releases the lever P. When the spring H acts to force down the piston F, the latter in turn forces the air, that is in the cylinder E, in jets through the nipples b, impinging against the edge of the sheet of paper, which acting with the turner C and brushes 14, serves to prevent more than one sheet of paper being lifted at a time. By the further rotation of the shaft 48,the vertically reciprocating frame B is raised Vby the cam 72, causing the front ends of the lever 83 to be raised by the pins 67, the turner remaining at rest. The rear ends of the lever 83 turn uponthe pins'85, as pivots, lso that the holders D, nipples b and front edge of the sheetof paper move'up in an arc of a circle, the pivot pins 85 being the center. This action continues until the guide-sleeve 77 abuts against the sleeve 91. When the turner is carried up to aheight sufficient for the foot-rod 87 and sheet of paper to be carried over the guard bar 9, itwill be seen that the nipples move with the edge of the sheet of paper and the air blast, which is so timed as to continue while the sheet is being turned and lifted', now ceases. The horizontally swinging frame A being now released, by the cam 47, swings forward until the foot-rod 87 has passed forward of the guard-bar 9. The vertically reciprocating frame B being now released, by the cam 72, begins to descend; both frames, now moving simultaneously, carry the sheet of paper forward and down until the cushion 101 abuts against the head of the buffet-screw 99, terminating the forward movement of the horizontally swinging frame A; the vertically reciprocating frame B and turner C still continue to descend until the foot-bar 87, of the turner C, strikes the rest 104 on the feedboard 2. When the turner stops the vertically reciprocating frame B still continues to descend, causing the pins 67 to carry the front ends of the levers 83 downward, thus turning the front-edge of the sheet of paper down until the sleeve 69 `abuts against the rest 103, which terminates the downward motion of the vertically reciprocating frame B;

vmeanwhile the bearing Z has raised the lever n, operating the three way stop-cock k, to cut oif connection of the holders D with the vacuum cylinder P. The sheet of paper being l IZO 'is released by the foot rod 87. By the f urther rotation or the shaft 48, the cam 47 operates to swing the horizontally swinging frame Aback; both levers moving simultargo neously upward and back until the vertically reciprocating frame B has reached the top of its stroke; the horizontally swinging frame A still continues to swing back until it completes its stroke, the buffets 105 preventing the movement from swinging beyond its proper limit. The vertically reciprocating frame B, being released by the cam 72, now descends until the foot rod 87 of the turner reaches the pile of paper. When the turner rests, the vertically reciprocating frame B still continues to descend until the holders D, rests 82 and nipples b are brought down upon the paper. The rests 82 serve to bear most of the weight of the vertically reciprocating frame B to release the holders D from undue pressure; meanwhile the piston F has been raised in the air blast cylinder E ready to repeat the operation.

I lay no claim to the frame 1, vacuum cylinder p, lever 10G, three way stop cock k, the shaft 48, friction roller 73,1ever 74, horizontal rock shaft 38, as these features were included in patents which have already been granted to me.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Paten t, is
