Abstract: 1,076,308. Pivots and linkages; plastic bearings. V. LANGEN, [trading as A. ENRENREICH & CIE]. May 17, 1966 [May 19, 1965], No. 21773/66. Reading E2F. In pivot joints, particularly for use in motor vehicle steering linkages, of the type comprising a joint casing closed at one end by a casing closure and carrying a bearing element with a joint pin, the pin and casing are of shaped but un-machined metal and the casing closure and bearing element are of plastics material. In Fig. 1, showing a joint providing both rotational and angular movement of the pin relative to the casing, the metal joint pin 2 has a shank passing through a bore in the segmental spherical, plastics bearing element 3, the element bearing against the similarly shaped inner wall of the metal casing 1. The pin has an enlarged head, with a shoulder 4 bearing against the upper face of the bearing element, and with a central elevation 5 bearing against the inner face of the plastics casing closure 6. Fig. 2 shows a joint having parts similar to those in Fig. 1 except that the inner wall of the casing 1 and the bearing element 8 are of truncated conical shape, the joint thus providing only for rotational movement of the pin about its axis. The joints are provided with seals, 7 and 10 respectively. The bearing ele-  ments may be formed of acetal resin, preferably having incorporated a lubricant (e.g. graphite), or of polyurethane, and the casing closure may be made of acetal resin, the metal parts are preferably formed from steel, e.g. by forging.

Abstract: 1393824 Fastener driving tools D HAUBOLD [trading as DIETER HAUBOLD INDUSTRIELLE NAGELGERATE] 10 May 1973 [17 May 1972] 22339/73 Heading B4C The air intake valve 12 for the cylinder of a pneumatically operated stapling or nailing tool incorporates a ball valve 27 so as to be operable only when the work contacting member 32 and the trigger 26 are in their operative positions at the same time, the ball valve being connected to the air intake valve by a tube 11 which passes through the compressed air reservoir 3. A pair of identical spool valves 16, 17 are provided one on each side of the ball valve 27 and are normally pressed down to the limit of their stops 22, 23 by the compressed air in the reservoir 3 as shown in Fig. 1. In this position air can pass seal rings 18, 20 but not seal rings 19, 21 to atmosphere, the tube 11 thereby communicating the air pressure to the intake valve 12 to keep it closed. Actuation alone of the trigger 26, Fig. 2, moves the seal ring 18 into its closed position and the seal ring 19 into its venting position so that the air pressure within the bore 25 still acts on the intake valve 12 through the tube 11. Actuation alone of the work contacting member (32), Fig. 3 (not shown), results in the air pressure within the bore (24) to still act on the intake valve 12 through the tube (11). When both the work contacting member and the trigger are in the operative position, the seal rings 18, 20 seal off the supply of air through the tube 11 so that the pressure on the intake valve 12 is relieved and the pressure within the reservoir 3 lifts the intake valve 12 to act on the piston 5.

Filed: 1945-08-30
Abstract: 598,135. Filling containers. ELLIOT, R. I. Aug. 30, 1945, No. 22409. [Class 94 (i)] [Also in Group XXX] In filling an open top container with powdered material to a predetermined level, there is provided an air outlet with an indicating device, e.g., a celluloid ball 27 responsive to the flow of displaced air, which device indicates when air ceases to be displaced by the material sealing the outlet or the inlet at the desired level. In the Figure, powdered material falls from a hopper 3 into a funnel 7 and then into a drum 1 which is placed on a vibratory platform 2 and is closed by a lid 23 attached to the bottom of the funnel 7. Air displaced from the drum, in passing out through an outlet 26 blows a celluloid ball 27 up into a cage 28. When the material piles up to a predetermined level, i.e., the bottom of the funnel 7 (or of the outlet 26 whichever is the lower), the outflow of air ceases and the fall of the ball 27 is the signal for an operator to lower a handle 20 so that the funnel 7 which is supported by stirrups 13 pivots upwardly about a shaft 15 and causes a valve 5 (which is fixed to the funnel) to seal the bottom of the hopper. The upper part 8 of the funnel is of canvas so as to bend. The lid 23 has a felt underside 24 to prevent air escaping and a flange 25 for locating the lid, and may also be secured flush on the end of the hopper 7. 29 is a counterweight.
