SPECIFICATION forming part of Letters Patent N 0. 629,512, dated July 25, 1899. Application filed November 18,1898 $erial No. 696,753. '(No modeL) To all whom it may concern: v Be it known that we, ARTHUR G. LEONARD,

ALONZO GRAFFAM, and BYRON R. WOLCOT'I,

One of the principal features of ourinven tion consists of an improved construction for producing the required horizontal reciprocation of the face-plate of the machine; and our invention is also concerned with other combinations and details of construction, all

of which will be fully set out in the annexed claims.

Referring to the accompanying drawings,

in which the same letters of reference are used to designate identical parts in all the views, Figure 1 is a side elevation of the complete machine with the framework and the hornpost in section to show the construction. Fig. 2 is a rear end elevation of the head of the machine, showing the clutch mechanism. Fig. 3 isa detail View, partially in section and on a larger scale, showing the construction and operation of the hammer-operating mechanism. Fig. 4 is a plan view of the same mechanism. Fig. 5 is a central horizontal sectional view on the line 5 5 of Figs. 1 and 2, but on a larger scale. Fig. 6 is a vertical sectional View on the line 6 6 of Fig. 5; and Fig. 7 is a sectional view on the line 7 7 of Fig. 5, showing the cam-disk for operating the peg-driving mechanism and the reciprocating face-plate.

A represents the main frame of the machine, which is of the general shape shown and is supported upon the base B, to which it is connected by bolts or otherwise, as may be de- The upper'portion thereof is of the substantially tubular shape shown and is adapted to receive thetubularlowerend of the 1 eled point B and rests against the shoulder :00

in place by the bolts G.

adjustable supporting member C. l The upper portion of the frame A is slotted, and the screw-bolts D, passing through lugs on either side of the slot, are arranged to contract the upper end to clamp the support G in the customary manner. The upper end of the support 0 terminatesin the flange-plate E, upon which the main frame F of the head is mounted to be adjustable longitudinally and held The driving-shaft H is mounted in the bearings J and K, which are formed integral with or otherwise suitably secured to the main frame F of the head. The driving-pulley L, with its accompanying loose pulley M, is loosely mounted on the shaft Hand has an annular channel N formed in its rear face, in which channel a hardened flanged disk 0 is secured by means of the bolts P. This disk 0 has the notch Q therein, which is formed with the square shoulder on one side and the somewhat gradual slope on the other side. The shaft H has splined onits rear end the sleeve R, which has pivotally mounted nates in the stud T, which cooperates with the notch Q. The sleeve R has formed upon or fastened to its'outer end the lugor arm U, and a helical expanding-springVisinterposed between the lug or arm U and the yoke S to hold the stud T in engagement with the notch Q. To disconnect the clutch and stop the machine, we provide the treadle W, pivoted to the base B and having the'link X, extending substantially vertically upward through the tubular portion of the support 0 to the arm Y, which is fastened to the rock-shaft Z, which is supported in a suitable bearing formed in one side of the support 0. The rock-shaft Z has rigidly connected therewith the arm A, (see Fig. 2,) which has its upper end curved, so as to extend around the flanged disk 0, and which terminates in an outwardly-beveled point B and a square shoulder O. v A coiled spring D or some other spring of a suitable form holds the treadle WV normally upward, 9

with the curved portion of the arm A resting against the flange of the disk 0. position of restthe stud T, forming the end of the yoke S, is cammed outward by t-hebev- Ina.

C, so that it is carried out of connection with the notch Q on the flange of the ring 0, and the shaft is held from movement. When the treadle'W is depressed to start the machine, the arm A is drawn away from the flange of the disk and the stud T is permitted to engage with the square shoulder of 'the notch Q under the stress of the spring V, and the shaft will be carried-with the rotation of the driving-pulley until the treadle Wis released, when the arm A, swinging into position, will cause the stud T to be cammed outward to release it from the clutch and to stop it from further movement by reason of its contact with the shoulder G.

The horizontal reciprocation of the faceplate E is effected by the following mechanism: Rigidly fastened on the shaft H is the cain-disk F,which has formed therein the camgroove G. In this cam-groove is located the antifriction-roller H, which is loosely mounted on the bearing-stud J, forming the end of the lever ,K. This lever K has pivoted at its other end the arm L, which is of the shape best shown in Fig. 5, and is screwed or otherwise rigidly fastened to the face-plate E. The fulcrum of the lever K is adjustable to furnish the necessary adjustment for the length of the stroke of the face-plate and is constructed as follows, especial reference being had to Fig. 6: The fulcrum M has its upper and lower ends screw-threaded to receive nuts, and the lower portion N thereof is squared to fit the longitudinal rectangular slot 0, formedin the base-plate F of the head of the machine. portion N serves to support the rectangular block Q, which is mounted to swing upon the round upper portion R of the fulcrum M. This squared or rectangular block Q is mounted in the longitudinal rectangularchannel S, formed in thelever K.- It will be seen that as the end of the lever carrying the antifriction-roller H is vibrated by means of the cam-groove G the other end will be vibrated.

in the opposite direction, the squared bearing-block Q swinging about the portion R of the fulcrum as an axis. The nut T, which can be manipulated through the aperture U in the base-plate F, serves to clamp the fulcrum in any desired position of adjustment to vary the horizontal movement of the faceplate. The nut V and the washer W serve to hold the squared bearing-block Q in position. The vertical reciprocation of the awl bearing-block X in the face-plate is accomplished by the eccentrically-mounted antifriction-roller Y on the enlarged head Z of the shaft H, which antifriction-roller cooperates with the horizontal slot A formed in the face of the awl bearing-block X.

To reciprocate the hammer B we provide the following mechanism, especial reference being had to Figs. 3 and 4:: The cam-disk F has on its Periphery a cam-lug 0 which occupies about sixty degrees of said periphery and is arranged on a constant curve, so as to A flange P above the square 7 raise the antifriction-roller D coiiperating therewith, uniformly while the cam is in operation. This antifriction-rollerD is mounted upon a circular bearing-stud E formed on the rock-shaft E, which is mounted in the in a yoke L in which is pivotally mounted in suitable bearings the rectangular block M which reciprocates back and forth in the elongated rectangular aperture N formedin the enlarged upper end 0 of the hammer B The length of the block M as comparedwith the width of the head 0 of the driver B is suflicient to permit of the horizontal reciprocation of the face-plate, with which the driver B moves, to occur without disturbing the connections between the lever K and the I driver B The plate J 2 has formed thereon or affixed thereto the cup-shaped projection P which has an aperture Q in its bottom. The lever K has formed therein directly above the cup P when the lever K is horizontal, a corresponding cup' R which has an aperture in its otherwise closed upper end. A bolt S which has a head T at its lower end, passes through the apertures in the cups P and B and is encircled by the strong expanding helical spring U The upper end of the bolt S projecting above the cup R is furnished with a nut and a lock-nut, by which the position of the lever K can be regulated as maybe desired. Owing to the high rate of speed at which the machineis operated, the peripheryof the cam-wheel E, which is rotating rapidly, would impart an extremely high rate of revolution to the antifrictionroller D In practice we adjust the nut and lock-nut on the bolt S so that the antifriction-roller D is just clear of the periphery of the cam-disk F on its circular portion. This takes the strain and friction off of the roller D and to a certain extent oif of the lever K except during the actual time that the cam is operating upon it. The coiled spring U serves to hold the lever K in its uppermost position and also cushions it in its downward movement. If desired, cushioning washers V, of leather, rubber, or other suitable material, may be placed upon the head T of the bolt S to cushion the impact of the head T with the under side of the cup P when the lever K returns to its uppermost position under the impulse of the spring II, when the cam ceases to act. To cushion the downward movement of the lever K and to provide a positive stop therefor, we fasten to the under side thereof in any desired manner the plate W which cooperates with cushioning material X, such as leather or rubber, which is placed in the cup-shaped head Y of the bolt Z screw-threaded in an aperture A in the base-plate F of the head of the machine. This screw-threaded bolt furnishes a fine adjustment for the buffer and stop and secures it in its adjusted position. We furnish it with a flange B which has a series of notches C therein, with one of which a tooth D which is fastened by screws to the plate J cooperates.

The knife operating in the tip of the horn E is substantially the same as that shown in our prior application referred to and need not be further described. The horn E is of the customary shape and has its lower end open and formed with the sleeve F the lower end of which rests on the shoulder G formed by the reduced upper portion of the tubular horn-post H The bore of this sleeve is somewhat larger than the diameter of the coset-screws J which serve to clamp the horn upon the horn-post, may-be thus used to regulate the position of the horn relative to the horn-post, thus furnishing any adjustment that may be found necessary to aline the aperture in the horn with the awl and hammer. The shank K of the knife is connected by the short lever L with the upper end of the knife-actuating rod M To permit of the necessary rotation of the born without affect ing the connections between the lever L and the rod M we make the lever L double or form one end thereof in a yoke, which has pivotally connected thereto the short sleeve N which is held between the nut O on the rod M and the nuts and lock-nut on the upper end of the rod. To permit of ready access to these connections for adjustment or otherwise, we construct the cap .1 of the shape shown in the sectional view in Fig. 1, which rests upon the upper end of the sleeve F The frameworkAhas formed therein the circular recesses Q and R in which are mounted the bearing-cups S and T The sleeve H has fastened thereto the cooperating cones U and V and the bearing-balls are disposed between these cones in the customary manner. The sleeve H has also fastened v thereon the bearing-sleeve cup W which The lower end of the sleeve H has swiveled thereon the block Z which has projecting downward therefrom the links A which are connected to the treadle B, so that when it is desired to depress the horn the downward pressure of the lever B will move the horn downward against the stress of the spring Y The details of the knife-actuating mechanism in addition to those already described are as follows: J ust adjacent to the camwheel F is another cam-wheel G which has a cam-groove D in its rear face, in which is mounted the antifriction-roller E upon the stud formed on the lever F, which is pivoted, as seen at Fig. 5, at one side of the base-plate necessary.

F of the head. This lever F has pivotally connected thereto a link G which extends down to the bell crank lever H", to which it is connected, which is mounted in the support J connected to the base B of the machine.

lower arm arranged with several holes, so that the thrust rod or tube L pivotally mounted thereon, may be adjusted as may be found The other end of this thrust-rod L is pivotally mounted to the lower arm of a similar bell-crank M mounted in a yoke N which projects downwardly from the swivelblock Z previously referred to. This bellcrank M is also arranged to permit of theadj ustment of the thrust-rod, and its horizontal arm is connected by a swivel O with the rod M previously referred to. As will be readily seen, this construction of the connections be tween the driving-sh a'f t and the knife permits of the actuation of the knife entirely unaffected by any change in the vertical or angular position of the horn. The arrangement of the bell-cranks H and M as shown is of importance, as it enables us to get the links G and M sufficiently close together so as not to make the machine cumbersome and at the same time enables us to lengthen out the thrust-rod L so that any angular variations in the direction thereof caused by the vertical movement of the horn will not affect the position of the knife.

Whilewe have shown our improvements as embodied in a machine of the type shown in our application Serial No. 610,323, filed October 28, 1896, we do not intend that these improvements shall be limited to that para ticular type of machine when they can. be used elsewhere. Moreover, we have not in the present application claimed any features which are disclosed in the prior application, which is for an entirely distinct and independ-' ent invention. V 1
