CHARLES S. JONAS AND RICHARD A. JONAS, OF BROOKLYN, NF.T YORK.-

WIRE-STITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 538,021, dated April 23, 1895.

Application tiled October 3, 1892. Serial No. 447,683. (No model.)

To all whom, it may concern.'

Be it known that we, CHARLES S. JONAS and RICHARD A. JONAS, citizens of the United States, residing at Brooklymin the county of Kings and State of New York, have invented new and useful Improvements in Wire-Stitching Machines, of which the following is a speciiication.

This invention relates to that'class of Wire stapling machines which are usually called wire stitching machines and which are employed for fastening the sheets of pamphlets and other blanks together by wire staples or stitches.

Heretofore the paper blanks were fed to the stitching machine by hand but this requires considerable care and attention on the part of the operator in order to produce approximately uniform work.

The object of our invention is to provide the machine with an automatic feed mechanism whereby the blanks are presented to the stitching mechanism and whereby uniformity in the work and greater speed are insured.

In the accompanying drawings, consisting of two sheets, Figure l is a front elevation of a wire stitching machine having a saddle table and providedwith our feed mechanism. Fig. 2 is a top plan view of thesame. Fig. 3 is a vertical transverse section in line :is-x, Fig. l. Fig. 4 is afragmentary sectional elevation similar to Fig.I 3 showing our feed mechanism applied to a wire stitching machine having a hat table. Fig. 5 is a fragmentary sectional elevation ofthe feed chain and one of its wings. Fig. 6 is a top plan view of the same.

Like letters of reference refer to like parts in the several figures.

A represents the main frame of a wire stitching machine; B, the stitching table arranged on the front side of the machine; C, the stitching head arranged over the table; D, the driving shaft journaled in the upper portion of the main frame, and d the driving pulley secured to the rear portion of the driving shaft. The stitching table may be either saddleshaped, as represented in Figs. 1, 2, and 3, for stitching folded pamphlet blanks, or flat, as represented in Fig. 4, for stitching flat or unfolded pamphlet blanks. All of these parts may be of any ordinary or suitable construction.

E represents the feed chain orlin'k belt provided with wings or flights F whereby the blanks are carried over the stitching table and presented successively to the stitching mechanism. This chain is arranged with its upper or carrying portion lengthwise in front of the stitching table and consists of chain links, each of which is provided with a dovetail tenon e on its outer side, as shown in Figs. 5 and 6. The wings project laterally or rearwardly from the feed chain and consist each of a supporting plate f which lis adapted to slide over the stitching table and support the blank, a stop or -abutment f formed on the rear end of the supporting plate and adapted to engage against the rear edge of the blank and push the blank forward, and a dove-tail socket f2 which engages with one of the tenons on the links and supports the wing.

The operator places the blanks upon the saddle or table between the wings, as the latter pass over the receiving portion of the table, so that the rear ends of the blanks rest upon the supporting plates ofl the wings. During -the forward movement of the feed chain or -belt the wings move the blanks forward and present the same successively to the stitching head which latter fastens the sheets of the blanks together by wire stitches. After the blanks have been stitched they are discharged over the delivery end of the stitching table. The feed chain travels with an intermittent movement and the stitching of the blanks is effected while the blanks and carrying mechanism are at rest. The wings can be shifted on the feed chain from one tenon to another to suit the length of the blanks. The tenons ofthe links and the sockets of the wings are preferably tapered lengthwise, as represented in Fig. 6, so as to cause the wings to be tightly wedged upon the links and firmly held in place.

G represents a curved guide secured to the front or receiving end of the stitching table for the purpose of guiding the wings upon the same. n

The receiving and deliveringy portions of the feed chain pass respectively around driving and delivering sprocket wheels h h secured to transverse shafts t' t". Eachof the latter is journaled in bearingsj formed upon the upwardly extending arms of a bifurcated support J.

K K represent hollow standards which receive depending shanks ZZ formed on the supports. These shanks are capable of vertical movement in the standards for the purpose of adjusting the feed chain with reference to the stitching table. The shanks are prevented from turning and also held in their adjusted position in the standards by set screws Z arranged in the standards and engaging in longitudinal grooves l2 formed in the Shanks. The standard K supporting the receiving end of the feed chain is rigidly secured to the door. The standard K supporting the delivery portion of the feed chain is made adjustable lengthwise of the feed chain for tightening thelatter by a dove-tail footn?l which is capable of moving in longitudinal guideways m formed in a base plate m2. The standard K is held in its adjusted position by means of bolts n passing through the foot m and longitudinal slots n formed in the base plate.

O represents a ratchet wheel secured to the rear end of the shaft supporting the driving sprocket wheel h, and p is a rock arm mounted loosely on said shaft adjacent to the ratchet wheel. This rock arm is provided with a pawl 1J' whichengages with the teeth of the ratchet wheel.

Q represents a rotating arm secured to the main shaft D ofthe stitching machine and connected with the outer end of the rock arm 1J by a rod q whereby an intermittent rotary motion-is imparted to the driving sprocket wheel of the feed chain. The throw of the ratchet mechanism is so adjusted that each revolution of the main driving shaft causes the rock arm to move the feed chain forward a distance equal to the space between two stitches on the blanks. For the purpose of varying the length of the throw of the ratchet mechanism and the length of the space between two stitches, the rotary arm Q is provided with a longitudinal slot q which receives a clamping bolt lr secured to the connecting rod. This permits the throw of the rock arm and pawl to be adjusted so that the movement of the feed chain corresponds with the size of the blanks and the space between two stitches. The detachable wings of the feed chain are also readily adj usted in accordance with the size of the blanks.

We claim as our invention* l. The combination with a stitching table and a wire stitching or stapling mechanism, of an intermittently moving feed chain or belt arranged along the stitching table and provided with feeding wings which are adj ustable lengthwise of the feed chain or belt, whereby the distance between the wings can be increased or reduced to correspond with the sizeof the blanks or pamphlets, substam tially as set forth.

2. The combination with a stitching table and a Wire stitching or stapling mechanism, of a feed chain or belt arranged along the stitching table and provided with feeding wings which are adjustable lengthwise of the feed chain or belt, and a variable intermittent actuating mechanism whereby the feed chain or belt is operated and the travel of the same lcan be increased or reduced tov correspond with the distance between the stitches or staples, substantially as set forth.

3. The combination with a stitching table and a wire stitching or stapling mechanism, of a feed chain or belt provided with laterally projecting feeding wings adapted to pass over said table and each previded with a supporting plate resting on the table and supporting the blank or pamphlet and with an upright abutment arranged along the rear edge of the supporting plate and whereby the blank or pamphlet is pushed along, substantially as set forth. y

4. The combination with the stitching table, of a feed chain or belt composed of links each of which is provided withl a dove-'tail tenon, and wings adapted to pass over the stitching table and provided with dove-tail sockets engaging with said tenons', substantially as set forth.

Witness our hands this 24th day of September, 1892.
