BOOK-BINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 338,726, dated March 30, 1886.

Application tiled September 1R, 1884. Serial No. 142,982. (No model To all whom, it may concern.-

Be it known that I, LEVI W. FIFIELD, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Book-Binding Machines, and I declare the following to be a description ofmy said invention suiiiciently full,

clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciiication.

The objects of my present invention are to provide means for delivering from a spool or continuous coil abinding strand, wire, or cord and laying the same longitudinally into the back of folded signatures of a book; also, to provide means for passing a series of needles through the backs of the signatures for carrying the holding-bands beneath said longitudinal binding-strands, and for securing the several signatures together, and to afford facilities for retaining the strand at proper intervals, and for severing it at positions desired. I attain these objects by mechanism the nature, construction, and operation of which are illustrated in the drawings, and explained in the following description, the particular sub- 30 ject-matter claimed being hereinafter definitely specified.

In the drawings, Figure l is avertical section, and Fig. 2 a front view, of a machine embracing the features of my invention. Fig. 3 is a front view of the devices for delivering and laying the longitudinal binding-strands, and the devices for supporting the signatures,

- shown separate from other portions of the mechanism, and on somewhat larger scale. Fig. 4 is a vertical sectional view of the cylinder and plate shown in Fig. 3. Fig. 5 is a sectional view,on larger scale, illustrating the manner of laying the binding-strands into the signatures, and showing the points of the needles for passing the transverse bands or cords through the backs of the signatures. Fig. 6

is a front View of a gripping device for holding the extended strand at the angles of the carrier-plate.

Fig. 7 is a plan View, of the Fig. 8 is a front view, showing the punch and chisel rods for pressing down and cutting off the longitudinal bindii'ig-strands,

and the devices for operating the same. Fig. 9 is a vertical section of the same a-tline X X. Fig. l() shows the manner in which a wire strand may be laid longitudinally into the signatures and bent at intervals corresponding with the nicks or cuts for the bands. Fig. 10 shows the manner in which a wire or cord strand may be laid into the fold without the bends at the nicks. Fig. 1l is a back view of the book. showing the series of signatures as passed onto the transverse needles. is a front view,illustrating a modified construction of the strand-carrier, the signature-bed, and the gripping mechanism. Fig. 13 is a side view of the strand-carrier devices similar t0 Fig. 12, and Fig. 14 is asectional View showing a modified construction of signature-supporter and needle-brace.

In referring to the drawings, the parts marked A represent the frame, which may be of any suitable form to properly support the operating mechanism.

B indicates a bed or cylinder for receiving and supporting the folded signatures while being operated upon.

C denotes the revoluble strand-carrier or device for feeding and placing the thread, wire, or binding-strand w longitudinally within the fold of the signature, and D indicates the needles for receiving the series of signatures and for drawing the transverse bands or tapes b through the nicks n beneath the binding-strands w. The strand-carrier C is made with a number of straight sides or divisions corresponding in length to the dimensions required for extending portions of the bindingstrand w the length of the signatures, and is provided at its several angles with suitable grippers or spring-jaws, c, for holding the said strands extended in a direct line along the side or edge of the carrier. The bindingstrand w may be of fine wire, linen cord, or other suitable material, and is taken from a spool or continuous coil, WV, and led onto the carrier C through a suitable guide, w', and tension device, so as to be taken by the several grippers as they are respectively brought into position by the revolution of the carrier C, as

Fig. 12`

IOO

indicated, the strand being thus wound onto the carrier at oneside as fast as it is used off at the other side. In the present instance the strand-carrier C is made as a rectangular plate. If preferred, it could be made pentagonal, hcxagonah'triangular, or ot' other polygonal form, the length of its l sides being in each case such as required combined therewith for imparting an intermittent rotative action thereto, and also a latch-dog or means for confining it at the several positions of adjustment with its sides parallel to the bed or cylinder B. The cylinder B is provided with longitudinal grooves e to receive the back of the signatures, and a series of fingers, B', extend outward from said grooves in a manner to form a V-shaped guide or cradle for receiving the folded signatures S. Annular grooves d are formed around the cylinder, in which lie the points of the needlesl I). VThe cylinder B is mounted for rotative action in bearings E', that are movable on guides A', so that the cylinder B and strandcarrier C can be brought into contact with each other. The bearings E' have connection with the reciprocating table E. which latter is operated toward and from the carrier C by means of connections G, cranks or cams G', and operating-shafts H H', or other suitable mechanism for effecting equivalent advancing and receding action of the bed B. AThe needles D are supported in connection with the table E, so as to follow the action of the cylinder B. Said needles D are provided with eyes, into which the cords or bands b are rove, so as to be drawn into the notches n as the needles are g pulled through the same when removing the book therefrom. Suitable springs, ff, are arranged beneath the bearings E to give yielding action as the cylinder meets the carrier C.'

K indicates a gear fitted upon the cylinder B, with a ratchet and pawl, and meshing with a rack, L, ou the standard L. When the cylinderis moved upward, the pawl slips and the gear turns without revolving the cylinder, but

when the cylinder descends the pawl engages and the cylinder is given a half-revolution, reversing the position of the fingers B' and bringing the opposite set of ngers into working position. A latch or spring-stop, Z, is provided in connection with one of the bearings E', for retaining the cylinder at positions of adjustment. 1

. I I indicate cutters for severing the wireor strand w when properly laid into the folds of the signatures, and J J indicate punches for bending wire strands w outward at the nicks or spaces n in the back of the signature. These punches J are not essential to the practical operation of the machine, and can in ordinary cases be omitted, but for working the particular kind of binding described in Patent No. 286, 254 saidl punches are desirable, and may be used. The form and action of the punches J and cutters I are similar, one being blunt and the other sharp. They are severally mounted for' reciprocative movement in inclined grooves on the frame, at the front of the carrier-plate, and so that their ends will pass down into line with the edge of said plate, suitable recesses, i, being formed therein, as indicated. The cutters I are moved up and down by a cam-rod, m, which is fixed t0 the slide-plate M, that works back and forth on ar Y l suitable guideway ou the head of the machine, motion being imparted thereto by a band attached to the wheels M' and to the plate M. The parts are actuated by the crank and rod m2 and tumbler mi, which latter is engaged and forced upward, when the cylinder is elevated, by a stud, m, that projects from'a portion'of the movable cylindersupporting frame. A piece of rawhide, N, or other suitable material, may be arranged on the cylinder, against which the edge of the chisel or cutter I operates for severing the strand. The cam-rod m runs in a'iiotch at the upper end of the cutter-shank, as indicated in Figs. 8 and 9. The cutters are pressedback into their grooves by the springplate o, and an offset, p, on the back of the bars, serves, Aby striking on the frame, to th row their lower end outward clear of the carrierplate C when said bars I and J are raised, so that the carrier can be revolved without interfering therewith.

Bvindicates a lever fulcrumed at 1', one arm of which is provided with a spring-link, R',

having at its end a lug or pin that latches into the openings t in the plate C. One side y of this pin is beveled ol` so that it will slip from the opening twhen the link moves back, the parts acting in the manner of a ratchet.v The opposite arm of the lever R is engaged by` a suitable catch on the moving bearing E', so as to eect the intermittent rotation of the strand-carrier C, to bring its several sides 'consecutively into position to receive the strand w and tolay it into'the folds of the respective kno signatures as the latter are brought into place by the cylinder or bed VB.

'I indicates a spring-finger for bending theend ofthe wire 'w away from the corner of the plate C, and T' denotes a point or prong arranged to enter between the jaws c, for discharging the portion of the strand w which is cut off and left within said jaws. The prong T' opens the jaws when the latter are brought in contact therewith by the rotation of the plate C.

On the driving-shaft H' is a friction-clutch pulley,U, for the driving-belt, and in connec` tion therewith is a treadle device, V, for' .throwing it into and out of action, and a trip` dog and leveroperating with the crankfshaft H, for throwing oi the clutch when the shaft H has made one revolution.

rIhe operation of my improved machine is as follows: The signatures S, after they are folded and prepared with the notches a, are laid upon the bed or cylinder B, between the rows of fingers B, one at a time, and with the fold or back toward the bed, as indicated in Fig. 4, the notches a being placed so as to correspond in position with the annular grooves d, and the line of the fold being parallel with the longitudinal groove e, while the leaves lie open from the fold in V shape and rest against the sides of the cradle. The placing of the signatures may be facilitated by a suitable guide attached to the bed and against which the heads of the signatures are placed. Vhen the signature is in place, the attendant depresses the treadle to throw the clutch into action with the driving-pulley, and as the machine is started the bed or cylinder B and the strand-carrier (l are, by the action of suitable mechanism, brought together, in the manner of a press, so that the edge ofthe carrier-plate, with the extended strand w, presses the signature into the groove e, and delivers the strand w closely into the fold throughout the length thereof. As the bed approaches the Strand carrier, the stud m'L comes in contact with and raises the tumbler m3 and rod m2, thus operating the wheels h and slide M, causing the cam-rod m to actuate the cutters I, which latter are forced down upon the strand w and severit at each end, so that the `portion laid into the f'old is freed from the carrier and remains lying longitudinally in the signature after the mechanism recedes. rlhe punches J, when employed, are also forced down in the same manner as the cutters I, and press the strand w through the nicks a. Vith the receding action ofthe bed-cylinder the ratchet ofthe gear K engages, and said gear causes the cylinder to turn one-half revolution. This carries the back of the signature toward the needles D,the points ofwhich lie in the grooves d, and as the cylinder turns over the needlepoints pass through the nicks a above the strand w, and the signature is transferred from the cylinder to the needles, and slides back out of the way of the fingers B, which are ready to receive the next signature. During the time of the above action the hook engages the lever R, and by swinging said lever effects, through the aid of the latching-arm R', the partial rotation ofthe strand-carrier C, to bring another of its sides, with a new portion of extended strand w, into position to receive the next movement of the bed and signature. At the rotation of the carrier the gripping devices are brought into action with the opening devices, and the short piece of strand material cut off and left in the grip-jaws is discharged therefrom, so that the grippers are ready to again receive the strand when brought up to the line where said strand is wound onto the carrier. Vhen the desired number of signatures has been passed onto the needles D, the bands b are threaded into the eyes of the needles D, and as the book is removed from the needles the bands are drawn into the notches u, beneath the strands w across the back. The ends of the strands w may be turned back over the ends ofthe signatures and be glued down upon thc back, or said ends can be otherwise disposed of, as desired.

The machine can be employed with either wire, linen twine, or other material for the strand w.

The modification illustrated in Figs. 12 and 13 is to show the strand-carrier C capable of adjustment. In this modification the carrier-Gis made with a series of arms radiating from a central revoluble shaft or aXis, C', and upon said arms the gripper-s c are adj ustabl y attached in such manner that they can be moved to or from the center C, for increasing or diminishing the extent of side or span.

The grippers c can be made, as indicated, with V-shaped jaws for holding the strand, and with springs c4 for discharging the end of the strand therefrom when said spring is brought into contact with the arm C5 as the carrier G revolves.

Set-screw sl may be arranged for clamping the .grippers in place upon the arms.

A presser or grooved follower, C, in separate piece from the strand-carrier may be arranged for forcing down the strand into the fold of the signatures, said follower being operated by action of the mechanism as the bed B is moved up tothe carrier C, or vice versa, the arm e coming in contact with the arm e5 of the follower.

The bed B may be reciprocative to and from the carrier by crank-shaft and connecting-link, in similar manner to that of Fig. 2, or by any convenient mechanism.

The modifications also show a bed for supporting the signatures, which is not revoluble, for transferring the signatures to the transverse needles D, but in which said needles are projected forward through the nicks a above the strands w, the parts being disposed, as in Fig. 14, wherein B* indicates a bar for supporting the needles D,whieh bar may be moved forward and back by any suitable mechanism, as desired, to carry the points of' the needles through the backs of the signatures, and the signatures being then allowed to pass back on the needles by the raising of the rear side of the cradle or si gnature-snp porting device, which can be effected by mechanism connected to the arms to operate as the bed descends. This lifting mechanism is not herein shown, as it is unimportant what form of mechanism is employed therefor.

The needles can be curved about the bedcylinder, as indicated in dotted line of D2, Fig. 5, so that the signature will be delivered at the other side of' the bed, if desired.

Vhat I claim as of my invention, to be herein secured by Letters Patent, is-

l. rlhe combination of the revoluble strandcarrier with a series of gripping devices, substantially as described, for receiving the binding-strand from a continuous coil or spool, and
