SPECIFICATION forming part of Letters Patent No. 356,793, dated February 1, 1887.

Application filed May 27, 1886. Serial No. 203,450. (No model.)

To all whom i2? may concern.-

Be it known that we, JussnW. Rrncuosn and DAVID A. Huron, citizens of the United States, residing at llleohanicsburg,Cumberland county, Pennsylvania, have invented certain new and useful Improvements in Punching- Machines, of which the following is a specification.

Our invention has for its object to punch or out openings at regular intervals in strips of leather or other materials, and to absolutely insure the cutting of a predetermined number of perforations in each strip; and the invention consists in combining with the punch certain registering mechanism whereby to plainly indicate to the attendants each perforation made, and certain throw out mechanism, whereby the operation of the punch upon the strip is automatically arrested as soon as the desired number of openings have been made.

The invention also consists in certain details of construction, fully described hereinafter, and illustrated in the accompanying drawings, in which Figure 1 is an elevation, in part section, of a punching-machine illustrating our invention. Fig. 2 is side elevation. Fig. 8 is a front elevation, part of the base being in section. Fig. 4 is a plan. Fig. 5 is a plan illustrating the centering clamps and connections. Figs. 6 and 7 are views illustrating the con struction of ordinary leather fly-nets. Fig. 8 is a View illustrating the feed devices; Fig. 9, a side view in part section; Fig. 10, an inverted plan; Fig. 11, a detached view showing a modification of the stop. I

In the manufacture of leather fly-nets for horses it is common to make them of longitudinal leather strips (1, Fl 6, and smaller cross-strips, b, the strips a having transverse perforations :r, Fig. 7, {or the passage of the strips 5. The perforations w are formed by the action of a cutter in a punchingmachine, and it is common for the attendant to count the strokes of the punch and arrest its action when the requisite number of perforations have been made. This mode of operation has proved most objectionable, as the attendant, through forgetfulncss, carelessness, or having his attention called from his work, frequently miscounis and the strips are removed from the machine with more or less than the desired nnmherof perforations, and the mistake is not discovered until the net is partially put together, resulting in considerable loss of time, and sometimes of material, to make the needed correction. To remedy this difficulty we provide a punching-machine, of any suitable construction, with a registering mechanism, which clearly indicates on a register each stroke of the punch, the index-hand or other pointer being capable of being set to zero prior to the introduction of each strip; and we also provide automatic means for throwing the punch out of action as soon as any predetermined number of perforations have been made.

Referring to the accompanying drawings, wherein is illustrated one form of machine which we have found to he very effective, the bed A of the machine is supported in an ele vated position on legs c c, and supports two standards, d d, and the former is extended to constitute a head, in which slides a bar, B, socheted at the lower end to receive two dotachable hollow cutters, e 6; but a single cutter of any desired shape may be substituted for the two cutters, the cutter or cutters, with the bar, constituting what we term the punch. The punch-bar is reciprocated vertically by the revolution of a counter-shaft, C, geared to and deriving motion from a driving-shaft, D, and carrying an eccentricpin, f, connected by a rod, to a lever, B, which is connected to the bar B by a link, 5/.

The lever E vibrates upon the eccentric por-' tion or hearing j of a shaft, F, which constitutes the fulcrum, and carries at the outer end an arm, G, which, when the bcaringj is in its lowest position, engages with the shoulder of a catch, H, pivoted to a pin, 3, on the side of the head, the parts then being in position to operate upon the strip, which is guided and fed below the cutter, as fully set forth hereinafter.

When the catch H is withdrawn from the arm G, the shaft F is released and will turn automatically to raise the nearingj to its highest position, thereby elevating the punch-bar andouttcr, so that the latter will no longer IOO operate on the strip, although the strip is fed and the cutter reciprocated, thus arresting the punching action without arresting the motion of the machine.

The shaft F is turned automatically to raise the lever E by a spring, I, connected by a link to the periphery of a grooved wheel, J, on the end of the shaft F, and at the lower end to a stud, 10, projecting from the head, and a handle, K, serves to turn back the shaft to lower the lever and bring the arm G into engage ment with the catch H, which is thrown upward by a spring, 5, and limited in its movement by a stop, 6.

' The registering or counting device is made the means of throwing back the catch H and releasing the arm G when the requisite number of holes have been punched.

In the construction shown the registering device is a disk, L, turning on a stud, 7, projecting from the side of the head and graduated and rotated to the extent of one graduation at each complete movement of the cutter through the medium of any suitable connecting devices. Thus the lever E actuates a spring-pawl, 7a, which engages with a ratchet, m, in the periphery of the disk L, and feeds the latter one step at each stroke of the lever.

WVhen the cutter is not to be thrown automatically out of operation, a pointer, y, (dotted lines, Fig. 2,) connected to the stud 7, may serve to indicate to the attendant the number of perforations made; but as this would render it necessary to keep close attention to the register, and as it is difficult to arrest the machine suddenly, we prefer to throw the cutter out of action without arresting the machine, and this is effected by providing the disk L with an adj ustahle stop, which by its contact with the catch H throws the latter away from the arm G.

As shown, the stop consists of a block, M, with a recess to receive a peripheral rib, m, on the disk, and a set-screw, n, by whichit may be set in any position. A friction-roller on the block M prevents frictional contact with the catch H. A pin, 1;, (dotted lines, Fig. 2,) strikes a stop on the head and prevents the disk from being turned back beyond its zero position, and the block M is then set at as many points fromzero as corresponds to the number of openings to be punched. The arm G is turned down and engages with the cat-eh, and. the operation of the machine begins and continues until the desired number of perforations have been made,when the stop strikes the catch, throws the latter from the arm G, and the cutters are then lifted out of operation.

To enable the disk to be set back to zero after the cutters are raised, the shaft F is provided with a disk, N, having a curved rib, P, of such length as to make contact with the tail of the pawl and lift the latter outof engagement with the ratchet m, except when the arm V G is down and locked to the catch H.

The strip to be punched is fed forward step by step, as hereinafter described.

It is necessary to center and hold prior to thedescent of the cutters, as the strip, being round, would otherwise be displaced. Thisis effectedbythe use of two movable jaws, (or one fixed and one movable jaw,) q g, on the bed-plate below the head, and separated when the strip is introduced and fed, and brought together when it is punched. One of many possible means for imparting motion to these jaws consists of avertical rock-shaft, Q, extending through the bed-plate, carrying at the lower end a cross-bar, Q, Fig. 5, connected by rods 8 s with slides t 15, extending through the base-plate and carrying the jaws q (1, so that when the shaft is turned inone direction the jaws are separated, and when turned in the opposite direction they are brought together, at which time the perforation is effected.

The shaft Q is provided at the upper end with an arm, 10, which, when struck by a lug, 12, on the cutter-bar,is swung in one direction, a spring, 13, connected to a stud and to one end of the crossbar Q, beneath the base-plate, turning the shaft in the opposite direction.

A presser-foot, R, is carried'by a lever, S, pivoted to the standard d, said lever also can rying a roller, at, which acts as an additional presserfoot and occupies aposition directly above a slot, .00 in the bed-plate, into which slot extends the serrated feeding-claw f of the feed-device. The lever S is connected to rise and fall with the arm G, or to be lifted when the catches are carried out of operative position. This may be donein different waysfor instance, by a rod hung to the eccentric bearing j and extending downward and connected to the lever S; or, as shown, the lever S may be connected to a rod, T, sliding in cars on the head, and to the upper end of which is pivoted a camlever, T, which when turned lifts the rod, and a rod, T connects the lever T to the arm G.

As it is requisite for the presser-foot to rise when the feed takes place, this is permitted by giving the rodT a spring-bearing by means the strip of a nut, 8, on the rod bearing on a coiled spring, 9, arranged between the nut and one of the guide-ears, and the lifting of the presserits upward bearing on the rolleru by the action of the feed-claw. The feed-claw f is secured to a bar, 9, sliding in a hearing, if, upon a plate, G the latter being pivoted by a bolt, 7?, toa bracket, H", extending downward from the bed of the machine, so as to vibrate in a vertical plane, carrying with it the feed-claw, to which a vertical reciprocating motion is also imparted, so as'to bring it against and carry it from the material to be'fed.

In order to impart the desired vertical motion to the bar g and its claw, we make use of an L-shaped lever, 1 pivoted by a pin,.j at one edge to an ear, k, of the plate G and connected at the other end to a reciprocating rod, K and a pin, m extends from the cor her of the lever through a slot, 31, in the bearing h into the bar 9 so that as the rod K is I15 foot is effected by the lifting of the strip and I moved back and forth longitudinally the lever l P will be vibrated upon the pin j and the bar ,1 and its claw will he raised and lowered.

The extentof and the vertical movement of the feed-claw are regulated by means of two set-screws, m at, extending through ears p 19" upon the plate 1 with their ends in position to be struck by the vertical arm of the lever as it vibrates between them.

The extent to which the vibrating plate G is moved upon its pivot depends upon the extent to which the rod K is moved in either direction after striking the set-screws m in.

The reciprocation of the rod K is effected by means of'a rock-shaft, If, turning in bracln ets M at the under side of the bed-plate, and provided with an arm, f, to which the rod K is jointed, and the extentof the reciprocation of the rod K is changed by changing the position of the pin 3, to which the end of the rod is pivoted. As one means of adjusting the pin a, it is shown as extending into a slide, N", latter is preferably curved, so that any change in the position of the pin to carry it to or from the axis of the shaft L will not change the position of the lever 1 A set-screw, r serves as a means of securing the slide N in position after adjustment.

By the construction shown all the movements of the feed-claw f are efiected by the rocking of the shaft L which derives its motion from any moving part of the machine. Thus as the shaft rocks in the direction of its arrow, Fig. 8, the lever l is first carried in the direction of its arrow, and the fcedclawf is lifted until the vertical arm of the lever l strikes the end of the set-screw m when the upward movement ceases. As the lever takes its bearing against the set-screw, the continued movement of the rod K carries the plate G and the feed-claw in the direction of the arrow 2 until the shaft I. ceases its movement. As the movement of the shaft L is reversed, as hereinafter described, the lever 1 is carried downward, and the claw is quickly drawn from contact with the work, and continues to descend until the lever 1 strikes the end of the set-screw at, when the plate 6' will be carried back to its first position.

In the manufacture of many articles-as, for instance, in the punching of thongs for flynets-it is sometimes necessary to impart an extended movement to the thong after each operation of the cutter. In order in such cases to insure the constant and uniform contact of the claw with the material, we impart to the claw a curved edge coinciding with a circle the center of which is the pint, around which the claw vibrates, so that whatever may he the extent of movement of the claw its working-edge will always occupy the same relation to the material. By the proper adjustment of the screws in? m and the slide N the extent to which the claw is elevated and the amount of movement imparted thereto may be the vibration of the lever K stance, eccentric stops, as shown in Fig. 11-

movable upon the arm (f, and the 1 regulated with the greatest facility, but wholly independently of each other.

Any other suitable adjustable stops may be substituted for the set-screws m m-as,i'or in and the pin .9" may be adjustable in a slot in the arm (f, instead of being carried by a slide.
