Abstract: 16,006. Wilson, A. H., and Bennyhoff, L. July 28. Rod-severing machines; bolts and the like, screwing into 'place and unscrewing.-In a machine are combined means for holding a wheel in place, a wrench for, unscrewing and screwing nuts on the bolts, meaus for starting the bolts, means for extracting the bolts, and jaws for clipping the ends of the bolts. The bench 1 has a longitudinal slot, to recede a post 4 on which the wheel hub is held. The post 4 has a wear plate 5 resting on the bed of the bench and on a guide lug in the slot. A pivot stud, passed through the slot 3 in which it may be longitudinally adjusted, carries a plate on which are standards 10, 11, 12, 13, in longitudinal series, the plate being capable of sliding and turning on the stud. The standards carry a horizontal drive shaft 14 with a crank handle, and a countershaft 16 journaled in the standards 10, 11 and driven by intermeshing pinions 17 ; both shafts may slide to an extent limited by the abutment of the pinions 17 on one of the shafts 10, 11, and their ends are connected by a link 18. One of a set of removable wrenches 19 carrying nut-ejecting springs 20 is screwed on the countershaft. Opposite the wrench, the standard 12 carries a fork on which is a bracket 22 with a plate which is pivoted to turn on a horizontal axis and carries in a sleeve a bracing-hook 24 longitudinally adjustable to grip the felloe while a nut is being removed or screwed on. The bolt clipping and removing means may be mounted on the same base-plate with the wrench, but, as shown, a separate plate 25 is pivoted on the bench so as to swing outwards and allow the hub post to be brought nearer the wrench when operating on small wheels. The plate 25 carries a casing 27, on the inner walls of which are longitudinal rails fitting within grooves on the outer walls of a draw-head 30 within the casing. The draw-head is moved by means of a rack on the casing engaging with a pinion on a transverse shaft 31 in the draw-head turned by a crank-handle. Within a recess in the draw-head a claw is mounted to swing about a vertical axis so as to take under the head of a bolt and withdraw it when the draw-head is moved away. When bolts are being extracted, the tyre abuts against a head 38 on the casing. An arm 39 is pivotally mounted on the transverse shaft 31, having an upwardly projecting hook 41 which is brought against the tail of a bolt when its nut has been removed, so that the bolt is started on moving the draw-head. A laterally swinging-plate 43 carries a post 42, recessed at its upper end to hold the arm 39 at its proper height. When the arm 39 is not in use, the plate 43 is turned so that its face end enters a recess 44, which may be formed by turning up the side edge of the plate 25. The bolt cutter or clipper comprises a main jaw 45 with a forked handle, the members of which are pivoted to ears 47 projecting from a plate 48 mounted to swing laterally on the base-plate 25 and a pivoted jaw 46 with a handle swinging between the members of this forked handle. A lug 49 on the supporting-plate takes into the socket 44 when the jaws are turned into their operative position, the lug 49 holding the plate 43 in an operative position. In order that the arm 39 may actuate the bolt clippers, it is formed with a recess 50, which receives a pin 51 on the handle end of the pivoted jaw 46 when the handle portions of the jaw are nearly erect, so that, on turning the shaft 31, the end of the bolt is sheared off. The pin is released from the recess by swinging the jaws backwards until the handle of the jaw 46 rests on a lug 52 on the plate 48 and disengages the pin.
