摘要： 122,881. Rogerson, W. H., and Bedson, N. P. Feb. 1, 1918. Addition to 112,152. Wire.-The machine for forming barbed wire described in the parent Specification is improved or modified by arranging that the cutters for the barbs move in a path substantially parallel to the welding die heads and improvements are also effected in the feed rollers for the main and transverse wires, in the welding circuit connexions, and in the winding drum for the finished wire. As shown, the welding electrodes 8, 9 are mounted in plungers 4 reciprocated in guides 1 by means of bell-cranks 7 actuated from a cam-shaft 6, and the electrodes may move relatively to the plunger against the action of adjustable springs. Alternatively, the electrodes 8, 9 may be carried at the ends of rocking levers. Cutters 14 are attached to the dies or electrodes 8, and move with these, and co-operate with adjustable cutters 15 fixed to the wire guides 20, which are secured in position by wedge-shaped members 41 so that they can be adjusted to allow for wear. The feed rollers are formed with reduced ends over which the wire passes and is normally free except when engaged for feed by adjustable segmental parts 18. The transverse wires are fed against adjustable stops, so that barbs of varying length may be cut. The dies 8, 9, Fig. 6, are in the secondary circuit of a transformer, the current to the primary coil of which is controlled by a rotary switch 27, comprising two relatively adjustable insulated disks fitted with connected metallic segments which control the timing of the current. When the dies 8, 9 move together completing the welding of the barb, contacts 22, 23 complete the primary circuit to a relay 24 which breaks the current directly, or through a contactor 26. The winding-up drum for the finished wire is driven by means of a series of planet wheels engaging a driven sunwheel, and also in engagement with a freely mounted annular gear which is braked by a brake controlled by a cable 38, Fig. 1, connected to a spring-controlled arm 31 provided with a notched wheel 30 around which the wire passes. If the drum is winding too quickly, the arm 31 is moved forwards, and the tension on the brake is relieved thereby diminishing the speed of the coil.

摘要： 7558. Law, E. A., and Rogerson, W. H. March 30. Fixed-abutment type; packing drums. - Relates to rotary engines of the fixed-abutment type with pistons having outwardly-sliding vanes. A casing a, Fig. 3, is shaped to form a working-chamber within which rotates a piston drum b, fitted with outwardly-sliding vanes f. Close contact between the drum and the upper part of the casing is maintained by a spring- pressed packing-bar l, Fig. 4. The sides of the casing comprise disks g, which rotate with the drum. The outer ends of the vanes are secured to rods j, Figs. 1 and 4, which pass to the outside of the casing, where opposite pairs are connected to frames s, Fig. 1, which are reciprocated by links and straps actuated by fixed eccentrics c, c , Fig. 4. Two ports o, p, Fig. 3, controlled by a valve m, Fig. 4, act alternatively as inlet and exhaust ports.

摘要： 112,152. Rogerson, W. H. Dec. 20, 1916. Wire.-In making barbed wire, pointed barbs are automatically positioned on the main wire and are bent and held in position until welded by electric transversely - moving welding dies. The main wire 25 is intermittently fed through automatically released spring-clamps 26 by rollers 23 driven by toothed gearing and carrying adjustable projections 24, and moves along a guide 27 to pairs of oppositely moving electric welding-dies 17, 18, Figs. 1 and 4, which have V-notched ends and are slidably mounted in plungers 4, which are simultaneously reciprocated by bell-cranks 7 actuated by toothed gearing 21, 22 from belt-driven fast and loose pulleys. The dies' are retracted by a spring 15 and carry separate insulated electrical connexions 20. The barb wires 38 pass around pulleys 35 through guides 36, automatically released spring clamps 26 , and are fed by rollers 37 through guides 40 so arranged as to slightly incline the ends of the wires, one passing above and one below the main wire 25. The wires are fed against a stop 40 and are held by the dies 17, 18 until cut off obliquely by transversely moving tools 42 operated by camactuated levers. The dies 17, 18 complete their movement and bend the barb wires into position when the contact actuating cam 46, Figs. 2 and 8, completes the welding circuit. An overload relay or suitable shunt breaks the circuit when the weld is completed. When the cam 46 closes the contact switch 47, a contactor 48 is engaged and switches in the high-tension side of a transformer and causes low-tension current to pass across the dies until the weld is completed and the current short-circuited by contact pieces 52. The current operating through an overload relay 49 then opens the contactor 48 to break the hightension circuit. When the overload relay opens it closes the circuit of a subsidiary coil 50, which prevents the plunger 51 from falling and completing the circuit of the solenoid 48 and consequently the high-tension circuit. When the switch 47 is opened, the circuit 50 is broken and the plunger 51 falls. The complete wire passes over a notched skeleton wheel 28, beneath a second spring-controlled wheel 30, over a third wheel 32, and a travelling wheel 34 to a reel.
