Title: Improvements in latches for doors
IPC: E05C1/16
Filed: 1923-08-04
Abstract: 218,858. James, J. H. Aug. 4, 1923. Latches, sliding. - A spring-actuated sliding latch 1 is formed from a sheet metal strip bent over at the ends to form the head 2 and having a helical spring 5 engaging a tongue 9 at the back of the head and a fixed tongue in the casing. The rear end of the latch is bifurcated, with flanges 7 for engaging the follower 15 secured to the handle 14, the shank 6 of which turns in a stamped up bearing 13 in the base plate 4. A metal plate 12 fitting over the bearing 13 and secured to the base plate 4 has a flange 11 with a tongue 10 serving to secure the other end of the spring 5. The flange 7 may be undercut so that the projection 17 of the follower engages recesses therein to form a steadying means for the bolt. Wings 16 on the bolt limit its outward movement, and the lugs of the bolt straddling the shank 6 limit its inward movement. In the form shown in Fig. 5, the bolt is bent as shown and guided by parallel walls of the casing 4 and lugs 18. A pin 21 rigidly secured to the tapped lug 11 on the casing and working in a slot in the turned-down lug 8 of the sides 20 of the bolt, carries the spring 5. The bolt is operated by the follower 15 acting on the lugs 7.

Title: Improvements in and relating to direction and movement signalling means for road vehicles
IPC: B60Q1/34
Filed: 1928-07-10
Abstract: 316,754. Pradeau, W. G. July 10, 1928. Road - traffic signals on vehicles. - Direction and movement signalling means for road vehicles comprise a dummy hand 52 or other device, moved out from a sleeve 18 by means of a lazytongs mechanism 23, 24. The sleeve 18 is of elliptical cross section and has an end plate 16 to which is attached a small housing containing a spindle 15, the whole being supported by a bracket 12. The mechanism is operated by a chain 40 which passes over the pulley 41 and is attached to a lug on the member 35 which is carried by the pivot 34 at the lower end of the lazytongs. The chain is attached to a hand operated quadrant. The first operation of the chain transmits a thrust to the outer end of the lazytongs through the members 35, 45 to assist in starting the movement of the hand 52, and the movement is continued by the ordinary operation of the members 23, 24. The thumb is pivoted so that the last movement of extension of the lazytongs causes the thumb to move outwards from the hand. A flexible sleeve 50 of waterproof material connects the hand and a sleeve 31 arranged to slide with the mechanism in the sleeve 18. The hand is returned to its initial position inside the sleeve 18 by a spring when the tension on the chain is removed. A system of levers 67, 69 is provided, and a chain is attached to the lever 67, for the purpose of causing the extended hand to oscillate on the spindle 15. The hand may carry a rear reflector and a lamp may be provided to illuminate the device.

Abstract: 1442521 Printing surfaces T FUNAHASHI 7 May 1974 [7 May 1973] 20077/74 Heading B6C [Also in Divisions B5 and C3] A rubber stamp, in which the stamping face bears raised portions in the mirror image of the design to be stamped is made of a vulcanized porous rubber material having inter-connected micropores (of mean diameter 0À07-0À104 mm.) and a hardness of 40-80‹ (as determined with a C-type hardness tester according to the Japan Rubber Association Standard SRS 0101). The porous rubber may comprise natural or synthetic rubber together with a synthetic resin, e.g. phenolic resin, polyvinyl chloride or a xylene resin. In the examples rubber stamp 3 having a stamping face 2, of the above porous rubber, were made in the forms shown in Figs. 1, 3 and 5, by vulcanizing a mixture of butadieneacrylonitrile rubber copolymer, sulphur, zinc oxide, dibenzothiazol disulphide, liquid rubber, process oil, carbon black, coumarone resin, an aminoketone, phenolic resin, polyvinyl chloride, lead sulphate and/or sodium chloride or sulphate in a metal mould having the desired pattern for the stamping face. The vulcanized moulded sheets were then washed with water to remove the sodium salt. In Example 3 two rubber materials were vulcanized on top of each other so as to produce a laminate having porous rubber layers 1 and 4 which were then arranged in a stamp next to an ink impregnated element 6 (Fig. 5).

A disc brake for motor vehicle wheels comprises a brake caliper 3 engaging round the brake disc edge and having one arm connected to an hydraulic brake cylinder 9 whose piston 10 carries one of the brake linings 2, the opposite arm of the caliper carrying the other brake lining 2 such that the hydraulic brake cylinder 9 is movably mounted in a cylindrical sleeve 4 on which is disposed a ring 5 made of flexible, resilient or deformable material provided with a spherical surface and retained in a corresponding ball and socket bearing 6 in the brake frame by means of a ball flange 7 and screws 8. The brake cylinder 9 is formed with a longitudinal groove 11 in which a screw 12 engages and which is screwed into the wall of the sleeve such as not to extend beyond the outer surface of the sleeve. The brake may be adjusted during the first operation of the brake when the ball-and-socket bearing 6 and ball flange 7 are only slightly tightened by means of the bolts 8. The ball- and-socket joint allows the caliper to take up its adjusted position so that when the bolts 8 have been further tightened the brake is ready for continuous operation.

Filed: 1937-07-22
Abstract: The individual parts of bombs, shells, and projectile bodies comprise artificial resin and a fabric or fibrous or filler substance, the parts being formed individually in a press under pressure and heat and subsequently combined in order to form the projectile body.  The individual parts, i.e. the base of the projectile, the cylindrical portion, and the pointed nose portion, may be formed from a plurality of layers of cellulose, asbestos, linen or cotton fabric, or paper impregnated with liquid artificial resin, or from a mixture of granulated or pulverized artificial resin, with or without the addition of phosphorescent substances, and a vegetable or mineral filler substance, such as small asbestos fibres.  The parts are formed with screw threads in order to be secured together.  The Specification as open to inspection under Sect. 91 comprises also a method in which the base and cylindrical portion of the projectile arc formed simultaneously by layering the fabric parts within one another until the desired thickness is obtained whereupon the superposed pieces are shaped in an ordinary cylindrical matrix consisting of a stamp and a hollow part.  The nose portion is then formed separately.  In forming this nose portion, the superposed layers may be slotted in order to facilitate shaping in a suitable matrix.  This subject-matter does not appear in the Specification as accepted.
