BOOK-SEWlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 265,463, dated October 3, 1882.

Application filed October 15, 1881.

To all whom it may concern:

Be it known that we, JESSE F. TAPLEY and GEORGE B. KILBoN, citizens of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have jointly invented new and useful Improvements in Book-Sewing Machines, of which the following` is a specification.

This invention relates to certain improvements in book-sewing machines by which the signatures,77 as they are termed, or folded leaves ofa book, are successively sewed through and through, having stitches of varying length made therein, as required for such work, and at the same time certain of said stitches are caused to be looped over or sewed through suitable binding-tapes running transversely across the united back edges of the signatures, the object being to provide a machine which will sew books more rapidly and with greater uniformity than can be done by hand, and which will insure a close and accurate arrangement ofthe book-leaves.

Lhe sewing devices proper of this machine are these ofthe well-known Singer shuttle-machine, or a similar one, which it is not deemed `necessary to describe or illustrate herein, eX-

cept in so far as regards certain prominent features thereof, for the purpose ct' showing the opera-tive rela-tion of the novel mechanism which (zo-operates with said sewing-machine to accomplish the book-sewing.

In the drawings forming part of this speciiication, Figure l is a perspective view of a book-sewing machine embodying the improvements herein described and claimed. Fig. 2 is a side elevation, partly in section, and having a part of the frame shown in dotted lines. Fig. 3 is a plan view. Figs. 4 and 5 are perspective views of detail parts occupying relative operative positions7 shown apart from the.

frame of the machine. Fig. 6 is a side elevation of detail parts. Fig. 7 is a perspective view of a portion of the work-table, showing the position of the work when being sewed and the needle-bar head of the sewing-machine. Fig. S shows the stitches and binding-tapes on the outside of the book-si gnature. trates detail parts offered-reversing mechanism.

Like letters referto like parts in the several figures.

The sewing-machine frame c2 is properly secured on frame A, and two horizontal guidei rods, n, are secured to said frame by proper supports.

A work table, h5, consisting of two end frames and an inclined front side, is carried upon the said guide-rods, the latter passing transversely through said end frames, one at their lower front ends and the other near their rear ends, in such a way that said table may slide freely from right to left thereon.

Upon said inclined front side of table h5 is fitted to slide in grooves on the inner sides of said frame-pieces a work-supi'iort, h6, having a removable upper side, if, whose ends are grooved to receivethe bent-around ends of said support, or other equivalent devices thereon, so that said side l4 may be slid up and down thereon, and a longitudinal rib runs along under said side cn support h6, which enters a groove in the lower edge of said side/L"L when the latter is pushed quite down, as seen in Fig. lo, and two hooks, o", hook over and hold said side in place.

A signature holder, 3, (shown raised up by dotted lines in Fig. 1,) is pivoted by its ends to the inner side of said frame-pieces of table if, and is adjusted to have its edge lie against said tablej ust below the slot through the latter, which slot is clearly shown in Fig. 3.

A tape-roller shaft, a, is hung in said framepieces to tableh, carrying onit a series of taperollcrs, 0, having friction-springs 04 thereon, whose ends bear on said shaft to cause said rollers to so resist rotation by pulling the tapes n as to cause the latter to be drawn straight, and said shaft itself is held against too free rotation, when said tapes are so pulled, by a spring, 05, which bears upon it where it projects through said frame-piece at one end, and a crank, fr, is provided by which said shaft may he rotated to wind the tapes on said rollers.

Tape-guides n2 are placed on a rod running across said table in front of said tape-rollers, through which the tapes a pass on their way to the table. The ends 0f said tapes are carried under the signature-holder i3 and over the slot in the table h5, and are secured between lower grooved edge of the side q'fof support h and the aforesaid rib on the latter, which enters the groove in said side, as shown in Fig. 10, and are there firmly held, hooks o3 preventing said side from sliding upward.

A rod, 0, is fixed in the aforesaid framepieces of table h5, quite to the rear side thereof, running parallel to the guide-rods n3, and on said rod 0 are fitted two stop-blocks, a4, which slide thereon, actuated by a screw-rod, ab, which passes through one end thereof', and which is provided with a right and left hand thread, so that by turning rod a5 said blocks are moved in opposite directions. The rear ends of blocks a4 project beyond the rear side of table h5, for the purpose hereinafter stated.

A feed-rack, d', is secured to table h5, with which a gear-wheel, d, engages to give said table the aforesaid motion back and forth upon said guide-rods and under the needle-bar.

rlwo pressure-rollers, (f, are hung on arms secured to the lower end ofthe head ofthe sewing-machine frame c2, (shown in Fig. 7,) and are adapted to roll against the rear face ofthe signature-holder s to press it closely against the work.

The mechanism for imparting the aforesaid feed motions to table h5 and for reversing its movements and for operating the sewing-machine in conjunction therewith is as follows: A. driving-shaft, B, adapted to be run by any suitable means, is geared to the main shaft U, on which is a loose gear, D, having a hub which adapts it for engagement with a clutch, F, which is splined to shaft (l, and is moved there on by the clutch-lever H in the usual manner. Gear D engages with gear c4 on shaft c, and thus gives the requisite reciprocating motion to the needle-bar e5, and also engages with gear c on shaft d2, whereby the requisite shuttle motion is obtained, and the necessary intermittent feed niotion is imparted to the reversinghook shaft d4 by the ac tion of cam di upon arm d5. Shaft C and clutch F having been set in motion, the intermediate mechanism by which table h5 is acted upon as aforesaid is pnt in connection with said shaft by pressing down either of the treadles a', both of which are by Y rods a, connected to the opposite arms ofthe treadle-yolie L 011 shaft K, whereby said shaft is rocked in two directions. One ofthe effects of rocking shaft K, as just stated, is to throw the upper end of theshipper-arnii thereon to one IOO TIO

IIS

and cause the other of said arms c to bear with the force of -spring c against the short arm s on the pawl-carrier b4. (See Fig. 5.) Therefore it' the pawl b5 which is a piston-pawl operatingin a cylindrical case by aspiral spring coiled around it to throw its thin end into the grooves across the edge ot' wheel c4) be now drawn back away from said wheel, the pawlcarrier, which swings freely on shaft c3, will be by one ot' said arms c thrown around until the arm s on the pawl-carrier strikes the opposite arm c, where it will stop at a position coincident with arm o2, as shown in Fig. 5. Said pawl-carrier in swinging, as above described, carries the pawl toward the upper or the lower side of the grooved feed-Wheel c4, which is txed on the feed-shaft c3, and lets said pawl drop into one of the grooves in said feed-wheel. Pawl-carrier b4 has a circular slot, fu', in it, in which the end of a pin fixed transversely in a bar, b3, enters. Said bar` b3 is given a vertical reciprocating motion by the rocking of shaft b', with which it is connected by arm b2 on said shait. Shaft b is given a rocking motion by the horizontal reciprocating` motion of the reversing-hook arm a5, which is connected with said shaft by means of the link b, connected to the end thereof', and the hooks a4. The end ot' said arm a5 to which the hooks a4 are pivoted, as seen in Fig. 9, is adapted to be carried up and down in said link b, so that one of said hooks may engage alternately with first one and then the other end ot' said link, and so rock shaft b' as to give arm b2 thereon a reciprocating motion from its highest point down or from its lowest point upward, carrying bar b3 with it. The aforesaid horizontal reciprocating motion is given to arm ctjointly by the spring a6 a-nd the arm d6 on shaft d, the latter being actuated by the action ot' cam d3 on shaft d2, as aforesaid. Said hook-carrying end of arm a5 is moved up and down in the link b, for the purpose above stated, by the movement of arm T on the rock-shaft K, with which arm a5 is connected by the rod ft2. After the paw] b5 has swung around with wheel c4L from below up, or vice versa, it comes to a rest about opposite to the axis of shaft c3, on which said wheel is fixed, and at this point it is necessary that the pawl be carried out of engagement with said wheel, so thatit may be carried back for another stroke.

To effect this result, a pawl-lifter, bf?, is providl ed, consisting of a vertical arm, t, pivoted by its lower end to the frame ofthe machine, and a horizontal arm pivoted to larm t, whose free end is supported near to and made to engage with a pin, o4, or some suitable projection on the hub of gear e or the shaft that carries it, so that at each revolution of the latter a block, w, (shown in Fig. 4,) will be pushed against the thin end of pawl b5 and disengage it from wheel c4, letting pawl-carrier b4 swing around, as aforesaid. A spring, o3, Fig. 3, draws said pawl-lifteragainstor toward said hub ot' gear c.

A vertical stop-lever, a3, is pivoted one end to an arm, W, on the rock-shaft K, and its lower end hangs loosely in a hole in part of the machine. Said lever Fis provided with a hookarin, "02, and said hook-arm stands in such a position in the rear of table h5 that when the latter has moved as far as it should to the right or to the left one of the stop-blocks a4 is carried against said hook-arm, and pushing lever a3 causes the end ot' arm W to swing over and shaft-K to be rocked, thereby operating` the above-described devices, whereby the machine is stopped by throwing arm J on shaft K to a vertical position and disengagingclutch Ffrom gear E.

In Work for which this machine is constructed it is generally required that there shall be both long and short stitch es sewed through thel signature o2, Fig. 8, the short stitches being made near each end and reaching over or through the tapes a and over or through the middle tape, as shown, and the long stitches intermediate between the tapes. To this end the feed-wheel c4 has the grooves in its periphery in which pawl b5 engages cut at irregular intervals. Also, provision is made whereby the requisite length of thread for short and long stitches is taken up from the thread-spool automatically as follows:

The end of the pawl-carrier b4 opposite to that in which the pawl is set is made in the form ofa gear-segment, (see Fig. 5,) and a takeup gear-segment, h4, is so hung as to engage with the toothed end of' said pawl-carrier. To said segment h4 is pivoted a connecting-rod, 7b3, which 'in turn is pivoted to an arn1,h, on a rock-shaft, h. This latter shaft is hung so as to reach forward by the side of and beyond the face of the needle-bar head of the sewing-machine, and has a downhanging arm, h2, thereon, to the end of which is pivoted a connecting-rod, 0J', which in turn is pivoted to a vibrating take-up bar, t', in the lower end of which is a stud, a, having a vertical thread -hole through it. (See Fig. 7.) A slotted hook, i2, is bent over the lower end ot' said vibrating bar z' and said stud-z. The thread from its spool passes down through the upper part of the slot in said hook i2, thence through the said holc in stud z, and thence through the lower part ot' said slot down to the needle, as shown in Fig. 7. Thus it will he seen that the extent of the vibrations ot' bar i by which the thread will be drawn from ,its spool for a stitch next to be triade will be exactly in accordance with the oscillatory movements ot' the pawl-carrier b4, whose movements determine the extent of the feed motion given to the table h5 as it carries the Work along under the needle.

A spring, e, Fig. 2, is adapted to bear frictionally against the face ot' the feed-gear d to insure steadiness of motion in the latter.

The operation ot this machine is as follows The table h5 is moved to one side, the tapes a are drawn from their rollers, and their ends are secured between the lower grooved edge of the side i4 of the work-support h6, and said side is there fastened by the hooks 03, so that lOO IOS

said parts will be in theposition shown in Fig. l. The signature-holder s is now lifted up, as shown in dotted lines, and a signature, 02, is placed upon the table in the position shown in Fig. 7, and the signature-holder is dropped down upon it, crowding its outwardly-placed leaves between it and said side i* and holding the signature down upon the table beneath, while the rest of its leaves lie upon that portion of the tapes a between the table and shaft a. Gare is taken that support h6 be moved sufficien tly toward the pressure-rolls e before placing the work as above described, to make sure that said signature-holder will be so pressed upon by said rollers as to hold the signature immovable while being sewed. It' in arranging the machine as above stated for sewing, said table is moved quite to the left for starting the stitching, the left-hand treadle is pressed down, rocking shaft K, so as to throw the end of arm J toward clutch I", engaging the latter with the hub of gear D and causing arm c2 to be swung downward against the lower one of the spring-arms c, carrying it away from the other one and making the upper one of said arms, through theaction of spring c', bear down upon the arm s on the pawl-carrier b Pawl b5 is now drawn away from engagement with wheel c, letting the pawl-carrier swing on shaft c3 and carry the pawl toward the upper side of said wheel to there engage in one of the grooves therein. The sewing devices are now operating, and by the aforesaid rocking of shaft K arm T thereon is thrown up, lifting the reversing-hook arm a5 up, so that one of hooks a* engages with the upper end of the link b, to which is given a vibratory Inovementby arm a5, causing pawl-carrier b, through the above-described connections with shaft b and the action of spring c', to have an oscillatory movement, which causes it to turn wheel c* in one direction and to give to shaft c3 and to gear 'd the requisite feed motion tor moving table h5, as above,described, the pawl-lifter bb' lifting the pawl away from wheel c1 when said pawl has swung down opposite said lifter. When thetablelt5 has been fed along the length ofthe signature itcarries, onelof the stop-blocks a* will be carried by said table against the arm 'r2 on the stop-lever 1.3, and said lever will thus be made to swingover and rock shaftK, causing arm J thereon to be swung to a perpendicular position, whereby clutch F will be drawn back and the machine stopped. After the abovenamed signature has been sewed the holder '133 is lifted up, the leaves of said signature which rested upon the tapes are turned forward against those lying against the side i4, and another signature is placed on the table against the rstone, the holderiS being let down upon it as before, and in so pressing said holder against the signature the support h6 is caused to slide slightly down the inclined side ot' the table, drawing the tapes with it, and is so moved as each successive signature is added, until all of the latter which go to make up a book shall have been sewed, and sewed to said tapes. As the sewing devices are operated the needle passes through said signatures, and down through the slot i5 in table h5, its lower end passing' beneath the bed proper-of the sewingmachine, where a shuttle operates with it in the ordinary way to complete the stitch. If it be desirable to sew stitches ot' an even length, the feed Wheel c4 may have its periphery grooved accordingly.
