1'0 all whom it may concern:

Be it known that I, WILLIAM FEHR, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Impro vements in Punching vlachines, of which the following is a specification.

My invention has relation to a punching machine; and in such connection 1t relates particularly to the construction and arrangement of punch holders and to means for adjustaioly supporting the same, and being a division of an application filed by me under date of December 22nd, 1905, Serial No. 292,946.

The principal objects of my invention are first, to provide a punching machine with a reciprocating frame or support carrying a series of adjustable punches adapted to punch or perforate a metal strip, or wire in one operation, at varying distances apart, so as to permit among others of the manufacture of heddles of varying lengths and with the usual end mortises and with one or more eyes second, to provide the punching or perforating machine with mechanism adapted to insure the slotting or piercing of the metal strip in the central longitudinal axis thereof, irrespective of variations in width; third, to provide such a machine with a standard in which the holders for the punches or knives are adjustably arranged so as to permit of the shifting and locking of the holders in any position given; and fourth, to provide the machine with sectional punch holders so as to permit of the removal and replacement of punches without disturbing the holders in the position given.

Thenature and scope of my invention will be more fully understood from the following I description, taken in connection with the accompanying drawings forming part hereof, in which Figure 1, is a view, illustrating in side elevation the punching machine for slotting or piercing a metal strip at various points, in

one operation, the manner of adj ustably supporting a series of punches and the holders in a reciprocating frame and the arrangement for permitting of the use of any desired number of punches therein. Fig. 2, is a crosssectional view of Fig. 1. Fig. 3, is a detail view, enlarged, illustrating in side elevation a punch holder and a punch held in position by the same. Fig. 4, is a similar view, illustrating partly in top or plan view and partly in section, the punch-holder with the punch removed therefrom, and a portion of a frame supporting the same. Figs. 5 and 6, are cross-sectional views of diiierent portions of the punch holder shown in Fig. 3. Figs. 7 and 8, are detail views, enlarged, illustrating respectively in top or plan view and in side elevation a locking plate for locking certain portions of the punch-holder to its support. Fig. 9, is a view partly in elevation and partly in section of the locking plate and of a bolt for clamping the plate to the punchholder support. Figs. 10, 11, 12 and 13, are respectively side and end elevations of punches or knives used in conjunction with the punching machine shown in Fig. 1. Fig. 14, is a detail view, enlarged, of a metal strip, and illustrating slots of varying length formed by the punches shown in Figs. 10 to 13 inclusive. Figs. 15 and 16, are similar views, enlarged, illustrating respectively in elevation and in top or plan view a punching die and a stripping plate carried by the same. Fig.- 17, is a similar view, illustrating in section the die and its stripping plate. Figs. 18 and. 19, are detail views, enlarged, of metal strips slotted with the aid of dies and stripping plates shown in Figs. 15, 16 and 17. Figs. 20, 21, 22 and 23, are detail views, illustrating respectively in vertical section and in top or plan view, a guide for the metal strip, and Figs. 24, 25 and 26, are detail views, illustrating respectively, in side and endelevation and in top or plan view a clamping arm for adjustably connecting the punching dies to a support.

Referring to the drawings, crepresents a standard to which are secured guides 0 adapted to afford to a frame 0 in the standard c, a range of reciprocatory movements in a vertical plane. These movements are imparted to the frame 0 by means of leverarms 0 extending from a sleeve 0", and held with their rounded heads 0 in engagement with the frame by a removable plate 0.

As shown in Fig. 2, the sleeve 0, carried by a shaft 0 of the standard 0, is provided with an arm 6 engaged by a lever-arm c, and the forked end 0 of the lever-arm c surrounds a roller arranged on a drivingshaft (L supported and actuated by means not shown and is provided with a roller a held in engagement with a cam (1 rigidly secured to the driving-shaft a hen the shaft a is rotated, the cam a by means of its throw portion a raises the lever-arm c", which in turn by means of the arm 0 and lever-arm c depresses the frame 0 in the standard cl As soon as the throw portion c of the cam a has passed the roller 0 the lever-arm 0 by means not shown, raises the frame 0 in the standard 0, to its normal inoperative position.

The frame 0 is provided with a horizontally arranged groove 0, communicating with a slot 0 which groove and slot permit of the connection of the punch-holder (l, with the frame 0 and of an adjustment of the same in a horizontal plane in the frame 0 Each of the punch-holders d, consists of two sections, one forming the support for the punch (Z or (P, proper, which consists of a plate (1 engaging with its lower laterally projecting end d*, the underside of the frame 0 and with an extension d, the slot 0 of the frame 0 and the other of a clamping plate d, to removably and adjustably clamp the res pective punches to their holders. As shown in Figs. 5 and 6, between the extension (i of the support (Z and the frame 0 in the slot 0 is arranged a locking-plate d, loosely connected with the extension (i by a bolt (Z which engages an opening (i of the plate d, and which serves to lock the support (1 to the frame 0 in the following preferred manner. In the lower portion of the support (1 are arranged threaded bolts d, having outwardly tapering or conical shaped heads (1 a certain portion of which is brought into engagement with depressions cl, arranged in locking-plate d, as shown in Fig. 8. When the bolts (Z are advanced in the support d the plate d, and extension (i of the support (1 are forced apart. and thus the same are securely clamped to the frame 0 for a purpose to be presently described. The punch d or LP, is held in a vertical position in its holder d, by engaging a depression (1, thereof, and the same for adjustably holding the same in engagement with the support d consists aside from the plate (Z of bolts (Z having heads (Z sliding in the groove 0 of the frame 0 and of nuts (Z which by hearing against the plate d force the same against the punch and at the same time the heads d against the frame 0 In order to adjust the punch in the holder d, in a vertical plane to compensate for wear, it is only necessary to slightly loosen the nuts d of the bolts (Z after which the punch can be readily moved in the depression d, of the support (i On the other hand by the removal of the clamping plate 01 from the support (Z by removing the nuts al from the bolts d, the punch can readily be removed therefrom for sharpening or for rethe punch to the exact placing by another punch, without in the least disturbing the position of the support (l in the frame 0 This feature of holding the punch-holder support in its proper position, is important as it insures the return of position previously occupied by the same. If it becomes necessary to adjust the punch-holder d, in its supporting frame 0 or to entirely remove the same therefrom, this can readily be accomplished by merely loosening the nuts (Z and the clamping bolts (1, after which the holder (1 can be shifted longitudinally in the frame 0".

As shown in Figs. 3, 4 and 6, holes (1, arranged in the clamping plate (1 permit of an access to the heads (Z of the clamping bolts (1, arranged in the support (Z to tighten or loosen the same with the aid of a suitable tool, not shown.

By the above described arrangement of the punch-holder d, in the supporting frame 0 it is obvious that heddles of varying lengths can be produced merely by changing the positions of the punch-holders with respect to each other. Furthermore, any number of slots can be punched in the metal strip or wire I), by adding the required number of punch-holders to the frame 0 The slots punched by the punches or knives d or (1*, in the metal strip 1), may be in proximity to each other, if desired, for which purpose certain of the holders d, are shifted to abut or to nearly so against each other. As shown in Figs. 1, 10, 11, 12 and 13, the punches d and d employed are of varying width owing tothe varying length of slots or openings necessary to be punched in the metal strip or wire I). Normally a heddle requires only two slots If, for the end mortises and one slot 6 for the eye as shown in Fig. 14. However, as hereinbefore stated heddles having any number of slots to form eyes and of any length and width may readily be formed in the metal strip 1), by the punches d and (1 in conjunction with dies 6, and stripping plates 6 to be presently more fully described.

As shown in Figs. 1 and 2, each of the dies 6, and their holders 6 are supported by a cross-bar c removably secured to the standard c, of the punching machine. The dies 0, proper, consist of two blocks 6 and 6 one of which is provided with a depression forming a slot (2 of a size sufficient to admit of the entrance of a punch therein. The blocks (2 and e, are removably secured to their respective holder 6 by clamping bolts 6, preferably bearing against the block 6 and thus holding both blocks securely in position in the holder e as shown in Figs. 15, 16 and 17. To the blocks 6 and e, are removably secured by means of bolts e a stripping plate 6 having an opening 0", held in alinement with the slot e, of the blocks. In addition to the opening (2, the stripping plate a, is provided with a depression 6 at its under side which is adapted to receive and to guide the metal strip or wire I), and to hold the same in position on the dies 6 and e When the punch (Z or (1 fitting the opening 6 in the stripping plate 6 and the slot 6", of the dies c and e", is actuated by the frame 0 the same pierces or punches in its descent the slots Z2 and 6 in the metal trip, as shown in Figs. 18 and 19. The strips of metal punched from the metal strip b, are forced through the opening 6 arranged in the dieholder 6 and leaves the same through a slot 0, arranged in the cross-bar 0 as will be readily understood in conjunction with Fig. 2. The dies 6, in order to render the same adjustable on the cross-bar c, are held in engagement therewith, by clamping brackets e bearing with one end against the crossbar 0 and with its other end against the stripping plate c of the die 6, as shown in Fig. 1. A belt 6 engaging with its head 6 a depression 0, arranged in the bracket c, and passing through slots, not shown, arranged in the cross-bar (2, permit in conjunction with nuts 6 of the ready adjustment of the dies 6, on the cross-bar or of the removal thereof, by the loosening of the nuts 6 on the bolts e, as will be readily understood in conjunction with Figs. 1, 24, 25 and 26.

In order to insure piercing or punching of the metal strip or wire I), in its central longitudinal axis and irrespective of its varying width, the following preferred mechanisms are employed :-As shown in Fig. 1, to each side of the dies 6, are arranged guides 6 each of which consists of a supporting plate 6 adjustably connected with the cross-bar c, by a bolt e passing through the slot 0 of the cross-bar c and secured to the same by a washer c and nut 6 as shown in Fig. 2. In the plate 6", is arranged a holder e supporting with its upwardly projecting end a yielding arm a, which is held adjustably thereon by a clamp e secured to the holder 6 as shown in Fig. 20. The free end 0 of the yielding arm 6 extends downward and between the same and the holder a, forming a rigid guide arm, passes the metal strip or wire I), and is held by the same in proper position with respect to the dies 6, of the punch ing machine. The yielding arm a, by permitting uneven or broader portions of the strip or wire I), to readily pass between the same and its holder e prevents a jamming of the strip 5, in the piercing or punching of the strip in the longitudinal central axis thereof. The guides 6 can be readily adjusted to accommodate strips of any desired width, by the mere adjustment of the screw 0 and spring 6 bearing from opposite sides against the holder 6, and thus permitting of a shifting of the same in the plate e", and by the loosening and tightening of the clamp a, bearing down upon the yieldingarm a, after which the same can be adjusted and reelamped in its position, as will be readily understood in conjunction with Figs. 20, 21, 22 and 23.
