'1' 11 7/ It'll/(Hit it lH ll l/ (Intern-IL:

it known that l, CHARLES F. TAYLOR, a citizen of the United States, residing at llartford, in the county of Hartford and State of Connecticut, have invented a new and useful Machine for Binding Pads or Tablets, of which the following is a specilication.

This invention relates to a machine which is designed to apply a strip of llexible material coated on one side with adhesive compound to the edges of packets or bunches of sheets of paper that are fed alongthe ma.- chine for the purpose of binding the sheets which are afterward trimmed or cut into pads, tablets, or composition-l ooks of the desired size for memorandum, writing, and drawing purposes.

The object of the invention is to produce a machine which will feed the packets of paper, render a binding-strip adhesive, apply the adhesive strip to the edges of the packets, cut the strip behind each bound packet, and deliver the bound packets to a drier.

ln the machine which is illustrated as em bodying this invention packets or bunches containing the required number of sheets of plain or ruled paper of the desired size are pushed along a table to aws which grasp the packets from above and below and carry them suitably spaced past a strip of cloth which is drawn from a reel and coated with glue on one side and is folded by rolls and a brush about the edges of the packets they are carried along. The strip of cloth is cut oll behind each bound packet by a pair of shears, and a pair of rolls deliver the bound packets after the strip is cut onto the vertically-movable arms of a drier, which retain the packets until they are removed by an attendant.

Figure 1 of the views shows a rear elevation of the machine. Fig. 2 shows an enlarged elevation of the holder for the rolls that are used to press the glued strip of cloth to the top and bottom faces along the edges of the packets. Fig. 3 shows a plan of these rolls and the holder. Fig. 4 shows an elevation of the drier end of the machine. Fig. shows a part of the drier-feed mechanism. Fig. (5 shows a detail of the drier and its 1 guide. Fig. 7 shows parts of several of the drier-slats and the connecting-chain. Fig. 8 shows in plan,on larger scale, the rolls, brush, and linger which press the glued strip to the edges of the packets and the shears which cut the strip. Fig. 9 shows in perspective the table with the front guides and the packet feeding mechanism. Fig. 10 shows avertical section of the frame on the plane indicated by the line 10 1() of Fig. 1. Fig. 11 shows a front elevation of a portion of the machine. Fig. 12 shows a rear elevation of a portion of the machine. Fig. 13 shows a section, on larger scale, of the paelmt-grasping mechanism on the plane indicated by the line 13 13 on Fig. 12. Fig. 14. shows an elevation of the same with parts broken away to show the construction. Fig. 15 shows a plan of the packet carrying and guiding parts and the strip applying and pressing mechanisms.

Packets or bunches P, containing the required number of plain or ruled sheets of paper of the desired size, are placed on the top of the table 1 and are pushed forwardly by a head 2, that is fastened to a rod 3, Figs. 1, 0, 11. The rod 3 is adjustablyconnected with an arm t, that is free to slide on a bar 5, which is attached to the endof the frame 6. A link 7 connects the arm with the upper end of a lever 8, which is pivoted to a bracket S), that is attached to a frame 10, fastened to the legs 11. This lever carries a roll 12, which engages a cam-grotwe 13 in the face of the cam-pulley 14:, that is mounted on the cam-shaft 15, which has a gear 16 in mesh with a pinion 17 on a shaft 18, bearing a driving-pulley19, Figs. 1-11. The rotation of the pulley through the pinion and gear causes the cam-groove to oscillate the lever, and this reciprocates the 'arm and rod with the pusher-heznl at the proper time for feeding forwardly the packets which are placed upon the table.

The pusher-head advances the packets between a pair of gripping-jaws, which after being closed together carry the packets forwardly still farther. The upper grippingjaw 2t) is adjustably connected with a horizontal plate 21, that is attached to a vertical slide .22. This slide is movable up and down in a carriage 23, that is movable along the inside of the front of the frame, Figs. 9, 10, 12, 13. The lower gripping-j aw 24 is attached to a horizontal bar 25, that is connected with a vertical slide 26, which is movable up and down in the carriage 23, Figs. 9, 10, 12, 13.

I The vertical slides, which carry the grippingjaws, are reciprocated oppositely, so as to cause the jaws to move toward and from each other by the horizontal movement of the slide 27, which has inclined slots 28, into which pins project from the slides, Figs. 12, 13, 14. When the horizontal slide is pushed forwardly, the slots and pins cause the vertical slides to close the aws together and grip two packets between them. lVhen the horizontal slide is drawn backwardly, the slots and pins cause the vertical slides to open the jaws from each other, Figs. 12, 13, 14.

The slotted slide is provided with a hook 29, that is adapted to be engaged by a hook 30 on an arm 31, that is pivoted to a horizontal slide 32. This latter slide is movable along the inside of the front of the frame and is connected by a link 33 with a bar 34, that is fastened to a block 35, which is movable longitudinally of the machine in a way 36, held above the cam-cylinder 37. This block is moved back and forth by the engagement of the ribs on the cam-cylinder with a roll attached to the under side of the block, Figs. 10, 12. The cam-cylinder by means of the cam -ribs drives the block forwardly and backwardly and causes the slide with the hinged finger to travel forwardly and backwardly. The forward movement of the camslide 32 causes the hooked arm 31 to engage the slotted slide 27 and first drive the slotted slide forwardly, so that the slots will close the jaws, and then after the jaws have been closed the continued forward movement of the slide pushes the carriage, with the jaws holding the packets, forwardly past the devices which apply the glued strip along the edge. The return movement of the slide 32 first draws the slotted slide backwardly and opens the jaws from the packets, and then after the jaws are open the carriage is drawn backwardly until the bail 38, that is attached to the hooked arm, encounters a wedge 39 on the top of the frame, Fig. 12, and raises the arm and disengages the hooks. The carriage then stops, with the jaws open, while the cam-slide, with the hooked arm, is drawn backwardly the full throw of the cam.

The backward movement of the j aw-carriage is limited by the position of the wedge 39 on the edge of the frame, the wedge being adjusted according to the length of the packets which are to be carried forward by the jaws. The cam-cylinder and cam-ribs are long enough to reciprocate the hooked arm and jaw-carriage the full distance of the longest packets that will ever need to be fed, and the wedge is adjustable in order that the l I I l hooked arm may be disengaged from the slotted slide and leave the jaw-carriage in such a position that the forward movement of the jaws will be equal to the length of the packets which they are at the moment to carry past the strip-applying devices.

To relieve the shock incident to the forward and backward movements of the jawcarriage, a block 40 is attached to the carriage in position to engage with a lever 41 at one end and a lever 42 at the other end of the limit of travel of the carriage. These levers are connected with pistons in dash-pots 43, adjustably secured to the front of the frame, Fig. 11.

The upper jaw is moved for varying the space between the jaws by means of an adjustable wedge 44 between the inclined block 45, fastened to the top of the upper jaw, and the horizontal plate which supports the upper jaw, Fig. 9. v

To procure such an accurate spacing and travel of the packets as will insure the cut ting of the strip between two packets, a block 46 is thrust between the two packets before the aws are closed. This block is re moved .before the aws are opened. The block is mounted on the end of a lever 47, which is pivoted on the upper-j aw carrier, and that extends across the machine and is connected by a link 48 with angle-lever 49. The engagement of the angle-lever with a set-screw 50, arranged on a fixed part, as the jaws reach the forward limit of movement causes the cross-lever to lift the block away from the lower jaw and from between the packets before any backward movement of the jaws takes place. The engagement of the angle-lever with the arm 51, adjustably attached to the frame, as the jaws reach the backward limit of movement causes the cross-lever to drop the block toward the lower jaw and between two packets. The forward movement of the jaws and block occurs before the jaws are closed, so that the packet in advance is pushed forwardly by the blockan exact distance. The jaws only hold the advance packet flat. The block keeps the packets separated the required distance and pushes the front one forward properly, Figs. 9, 10,11.

Then the packets are advanced by the pusherhead, they are directed by a guide 52, which is pressed backwardly by springs 53 against rolls 54, loosely mounted on vertical arbors located along the back of the frame, and when the jaws carry the bunches of paper forwardly a guide 55 presses them rearwardly toward the devices which apply the glued strip, which is drawn along by the packets as they are fed by reason of the adhesion of the adhesive compound to the edges of the bunches, Figs. 1, 9.

The strip, which may be cut from any suitable kind of cloth or paper, is wound upon a reel 56, that is supported by a frame 57 back of the machine. The strip in the form of machine shown is carried around rolls to a roll 59, that dips into a glue-vat 6t) and applies glue to one side of the strip. The glue is preferably kept hot by a lamp 61, and the surplus quantity is removed from the strip by a scraper 62, Fig. 4. This adhesive of course may be any other suitable compound besides glue, and, if desired, the strip itself may have been previously coated with an adhesive compound, in which case the roll 5?) instead of applying the adhesive would simply apply moisture for the purpose of softening the adhesive compound.

After passing the glue-roll the strip turns and runs along rolls 63, loosely mounted on vertical arbors located along the back of the frame. There may be any desired munber of rolls on vertical arbors, and the strip of course runs past them with the glued side toward the edge of the packets that are being carried along the top of the table by the aws and that as they are 'arried along are pressed toward the rolls by the guide 55. These rolls press the glued strip against the edges of the packets, Figs. 8, 15.

\djustably attached to the edge of the frame beyond the rolls on vertical arbors is a brush 6-l-, that is arranged so that its bristles will yiel lingly press the strip against the edge and on the top and bottom near the edge of the packets as they are carried along, Figs. 5, 15.

Mounted on the edge of the frame beyond the brush is a pair of rolls 65, loosely mounted on verticz l arbors, one of which lies below and the other above the edges of the packets. These rolls rub the strip with their flat faces against the upper and lower surfaces of the packets as they are carried along, Fig. Supported beyond the rolls on the vertical arbors are a pair of rolls 66 on horizontal arbors, one of which is arranged to run below and the other above the edges of the packets, so that they will press the strip with their circular faces against the upper and lower surfaces of the packets, Fig. 6. These rolls are loosely held by a frame 67, so that they will press the strip against the su faces of the packets. The rear faces of these rolls are provided with ratchet-teeth 68, which are engaged by spring-fingers 60, so that the rolls will only turn forwardly, Figs. 2, 3. Mounted in advance of the rolls 66 is an arm 70, which is attached to the frame and that has a bent spring-linger 71, that rubs against the strip and presses it closely to the edges of the packets as they are fed past, Fig. 8.

An upper shear-blade 72, that extends over the path of the strip, is mounted on a vertical slide 73, that is connected by a link '74 with a lever 75. A lower shear-blade 76, that extends below the path of the strip, is mounted on a verticz l slide 77, that is connected by a link 78 with the lever 75. The link 74 is connected on one side and the link 78 is connected on the other side of the pivot of the lever 75, Fig. 10. This lever is pulled in one direction by a spring 79 and is swung in the other direction by 1 :am St) on the :am-shaft 15, Figs. 1, 8, 10. The rotation of this cam and the oscillation of this lever through the links reciprocates the slides and :auses the sh ar-blades to cut the strip of cloth. The cam is so timed that the shearblades come togethe' and cut the cloth between the bound packet and the packet following.

When the aws are opened, the packet in advance is carried for\ 'ardly by two pulleys 81 until its front end strikes an adjustable stop D2, which retains it between a pair of drier-arms 83. These pulleys are belted to a shaft 8 t, which is bolted to the am-shaft, Figs. 1, t.

The drier in this instance is an elevator. The arms 8?) of the drier that is illut-rated are fastened to slats 86, that are connected near ach end by a chain 87. The chains run around sprocketwheels 88 on shafts supported at the top and bottom of the drier-frame, Figs. 4, 7. On each end of ach slat is a plate 89, that extends between the vertical bars EN), which form part of the drier-frame and which guide the slats as they are carried around by the sprockets and chains, Figs. 4 to 6. On the shaft of the upper sprocketwheel is a fixed ratchet-wheel 11 and a loose segmental gear 92, on which loose gear is z pawl 93, that is held in engagement with the teeth of the ratchet-wheel by a spring 94. Supported by the head of the drier is a 'ack 95, that meshes with the segmental gear, Fig. 5. This rack is connected by a rod 96 with a lever 97, that is pivoted to the lower part of the frame, and is oscillated by a cam 98 on the cam-shaft, Figs. 1, 10. The rotation of this 'am oscillates the lever and auses the rod at the proper time to reciprocate the rack and oscillate the segmental gear in such manner to intermittently rotate the upper sprocket wheel. This intermittently feeds the chains and slats with the drier-arms and carries the bound packets up on one sid and down on the other side of the drier-frame, Figs. 1, t. When the bound packets reach the lower portion of the opposite side of the drier from where they entered, they are removed by an attendant.

This machine may be used for applying strips of any suitable fabric cut any desired width and coated with any kind of adhesive to the edges of packets or bunches containing any desired number of sheets of plain or ruled paper of any quality and character which may be cut to the required size for forming pads or tablets or composition-books, but which, as most preferred, are of such length that they are afterward cut up in another machine into pads, tablets, or books, as the case may be, of the finished size.

The packets are fed into this machine by an attendant, and the machine continues to apply and press down the strip coated with adhesive compound and deliver the bound packets to the drier as long as they are fed and the adhesive strip lasts. This machine is adjustable for various sizes and thicknesses of packets, and by the time the packets reach the lower end of the drier the adhesive is sufficiently hardened to permit the packets to be removed to the trimming or cutting machine or to be stacked away.
