Abstract: 222,504. Crouchet, P. Sept. 28, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Angular bending; brcaking; shearing; punching; shcar-blades; punches.-A device which can be provided with 'detachable parts so as to constitute a vice, or a machine for shearing, bending, cutting, straightening or breaking metal rods or the like, consists of a clamp 2, adapted to be attached to a bench 1<a>, and a frame provided with apertures to engage with screws on the clamp and thus be secured either in a vertical or a horizontal position, the frame carrying a screwed spindle by means of which pressure is exerted on the detachable parts. The frame consists of two elbowed side members 6 joined by cross-pieces 5, 7, the piece 5 having apertures 9 adapted to hook over screws 10 or 11 on the clamp by which the frame is secured in either a vertical or horizontal position. A square-threaded spindle 8, for operating the detachable parts, is carried by the second end member 7. To adapt the device for shearing or cutting or as a vice, two jaws 12,13 are utilized, these being provided with guiding rods 16, 17 and pressed apart by a spring 14, their outward movement being limited by a plate 20 having elongated slots 22 engaged by screws 21 on the jaws. The jaws are held in the frame by a shoulder 25 on the jaw 12, nesting on the cross-piece 5, and by the engagement respectively with recesses 23 and 27a in the jaws 12, 13 of a screw-head 24 on the clamp and a pin 26 on the end of the spindle 8. The pin 26 is hollowed at its end to engage a ball 27 in the recess 27<a>. Recesses 42 are provided on the jaws to receive some of the detachable fittings. To use the device for cutting metal rods, cutting knives 30, 31, Figs. 1 and 2, are attached by screws 28, 29 to the jaws 12, 13, and the lower edges of the knives are guided in a groove 32 in the plate 20 to prevent buckling of the knives. Shearing blades 35, 36, Fig. 3, can be attached to the opposite side of the jaws 12, 13 by screws 33, 34, 37, 38, slots being provided to engage over the screws. A gauge for use in cutting off a number of pieces of rod of the same length consists of a bar 39, Figs. 1 and 2, mounted in the jaw 12 where it is gripped by a screw 41, and provided with a flat face 40 against which the end of the rod is placed. For punching, two angleshaped members 51, 52, Fig. 4, are secured in the recesses 42, one being provided with a punch and the other with a coacting die, and also with an extension 53 forming a guide for the punch and for the plate to be punched. A hole is provided in the jaw 13 for the removal of the punchings. For bending, straightening or breaking a rod, the frame 5, 6, 7, is attached to the clamp 2 in a vertical position, Figs. 7 and 8. The jaws 12, 13 are not used, a nose-piece 54 being attached to the end 26 of the spindle 8. A notch 55 in the piece 54 corresponds with notches 57 in the shoulders 58 on the side members 6 of the frame, and these notches hold a round rod or a square rod on edge while the pressure is being applied to bend or straighten it. To bend a square rod which is resting with its flat side on the shoulders 58, a stop is placed on the shoulders 58 and the nosepiece 54 is turned through a right-angle. To break a rod, the rod is given a saw cut on the top and bottom surfaces where it is to be broken, and pressure is applied at that point as for bending.
