    • 126,372. Sloper, T. Jan. 18, 1917. Pneumatic springs.-A shock-absorber particularly applicable for aeroplanes is formed of an annular chamber built up of internal and external walls A of material preferably inelastic as regards its length and somewhat elastic transversely such as the Palmer fabric for tyres. The ends are closed by two part rings A held together by screws and holding the beaded ends of the walls, which may have transverse pins. Inelastic rings A compress the outer wall and inelastic sectional spiders E extend the inner wall, the feet of the spiders acting as brake shoes on a central tube C. The ends of the chamber are connected by yokes B to the tubes B, C, which are suitable slotted and are connected by a helical returning spring D. In a modified form, the inner wall of the chamber is omitted and one of the walls is placed outside the chamber, the sectional braking spiders being arranged outside the chamber.

    • 120,957. Sloper, T. Nov. 23, 1917. Circular-saw machines. - In a machine for sawing coils from a cylindrical spiral, as in the manufacture of rims for bicycle wheels, an arm D, D for supporting the spiral E is set out from the frame A of the machine so that the spiral can be passed along it clear of the frame, the part D being thin enough to pass between the coils of the spiral so that each coil, when severed, can be removed by a screw-like motion. An arm B pivoted at B carries a saw C and is overhung from the frame A so that the saw lies above a clamp E , E , the end coil is supported while being severed. The saw is fed downwards by a screw B . The movable jaw E of the clamp is carried by a lever E counterweighted at E so that normally the clamp is open, and the clamp is closed by a cam F operated by a lever F. According to a modification, the clamp is arranged so that the end coil of the spiral in moved past the arm D before it is severed.

    • 19,316. Sloper, T. Sept. 1. Insulators.-Relates to insulators for aerial strainers &c. and to a process and tools for their manufacture, the insulators being of the kind made by winding rubbered thread on a former to obtain an elongated loop, and collapsing the sides of the loop to form end eyes for the reception of metal thimbles, the insulator being then lashed at its ends and finally coated with rubber and vulcanized. The rubbered threads A are wound on a former B, and placed for compression between the base C and die D of a press tool, Figs. 5 and 7, formed with recesses C , D to shape the loop, the recess D being formed on a tongue D' which enters the recess C . The base C has a through slot C to fit the former B and provided. with an enlargement C . Pins D guide the die D in the base C. The former B may be removed from the threads A while they are held compressed between the dies, to prevent their becoming displaced by a driver E having pins E passing through slot D' in the die D, as shown in Fig. 7. The loop is then removed from the dies and its sides are collapsed to form end eyes to receive metal thimbles A and rubber filling-pieces A surrounding the thimbles, Fig. 3. The insulator is next lashed with binding-thread A except at its extreme ends to stiffen it, and it is finally coated with rubber F and vulcanized. Sometimes a coating of varnish is applied to increase the insulating properties, the binding-thread A' preventing undue bending of the insulator and cracking of the varnish. Rubber water-sheds G, H, J as shown in Figs. 4, 9, and 10 may be built up on the exterior of the insulator.
