Abstract: 727,764. Covering cans. ELGIN MANUFACTURING CO. Feb. 3, 1953, No. 3022/53. Class 125 (2). [Also in Groups II and XXX] Cans 111 are fed in a continuous line by a conveyer 11 to actuate a trigger 110 which oscillates cams 71, 76 to release the lowest cover from a cover magazine which comprises four rods 47, 54, 63, 68 arranged in a square, the opposed rods 47, 54 being mounted on brackets 46, 52 and the opposed rods 63, 68 being mounted on floating blocks 60,65 slidably mounted on rods 48, 55 and 49, 56 which extend from the brackets 46, 52. These brackets are carried on castings 12, 26, the former of which is mounted on an upright 10 and the latter of which slides on bars 24, 25 extending from the casting 12. Screws 29, 30 engage the casting 26, pass through the casting 12 and carry bevel gears 31, 32 rotated by a shaft 35 fitted with a hand crank 38. Rotation of this crank alters the spacing of the castings 12, 26 and hence alters the size of the square formed by the magazine rods so that different diameters of covers can be accommodated. To accommodate different heights of can, the casting 12 can be clamped at different heights on the upright 10 by hand wheels 21. The cams 71, 76 have two lips 101, 103 which engage beneath the lowest and the second lowest covers respectively at the appropriate time. The cams are carried at the lower ends of studs 70, 75 the upper ends of which carry levers 72, 77 connected by a link 73a which has a pin and slot connection with the lever 77. The connection is clamped by a thumbscrew 86 in the position appropriate to the size of the cover being used. The levers 72, 77 are biased to cover retaining position by springs 94, 95 and rest against stops 96, 97. The studs 70, 75 are rotated to release a cover by levers 88, 89 actuated by a solenoid 91 energized when a can arrives beneath the magazine by a switch 117 closed by the trigger 110. One of the magazine rods may be removable for filling the magazine. As shown in Fig. 9, the covers 133 instead of dropping directly on to the can, are held on a bracket 130 attached to the rod 68 and are drawn therefrom by the advancing cans. As shown in Fig. 10, the covers are dropped by the cams on to a shoot 150 in which they are retained by a finger 176a which is spring loaded and which, when pushed aside by a can, rides round the periphery of the cover to centre it on the can. In a further modification, Fig. 15 (not shown), the covers are fed one by one to a covertreating machine which actuates the release cams.

Abstract: 363,539. Brakes. SOC. ANON. DES ANCIENS ETABLISSEMENTS PANHARD ET LEVASSOR, 19, Avenue d'lvry, Paris. Feb. 3, 1931, No. 3482. Convention date, Feb. 14,.1930. [Class 103 (i).] The rear-axle casing of a motor vehicle is so connected to the chassis that it can move yieldingly backwards and forwards relatively to the latter, and the brake-control rigging is so arranged that when the brakes are applied by the driver, the rear-axle casing moves backwards with respect to the chassis and automatically increases the braking action. The chassis 2, fitted with front and rear brakes, is suspended on the rear-axle casing 1 by a spring 3 and hangers 4, and the thrust tube 5, through which passes the driving shaft 23, bears against a cross-member 6 of the chassis. Secured to the front end of the tube is a spherical socket 5a engaging a ball 5b rigid with a sleeve 5c adapted to slide in a bush 18 secured to the chassis, a flange 19 on the sleeve normally bearing against the member 6 under the action of springs 7. The ball 5b houses the gimbal 21 connecting the main shaft 22 with the driving shaft 23. When the driver depresses the pedal 15 he operates the brake levers 8, 9 through the rigging 16, 17, 13, 12, 11, 10 and the resulting braking action produces a relative backward movement of the casing 1, the tube 5 and the shaft 13 with respect to the forwardly-moving chassis which causes the levers 17, 12 to rotate further in the direction for applying the brakes. In a modification the shaft 13 is mounted in brackets on the chassis of a vehicle having rear brakes only..
