Abstract: 1,252,513. Disc-brake wear adjustment; transmitting mechanism. W. BUSCH and H. FRIEDERICHS [trading as BERGISCHESTAHL INDUSTRIE]. 14 May, 1969 [11 June, 1968], No. 24596/69. Heading F2E.  In automatic wear-adjusting means for the linings of vehicle disc brakes of the kind in which the shoes 12, 13 are carried by brake-actuating levers 14, 16, interconnected by a brake bridge 17 of variable length, an auxiliary lever 18 is pivotally mounted at a fixed point 19 on the vehicle and is also mounted on the pivot which joins one of the brake shoes to that actuating lever to which braking force is applied, and compressible means carried by the brake bridge are so arranged as to be engaged and compressed by the auxiliary lever upon wear of the brake lining to reduce the length of the brake bridge. As shown in Fig. 2, a pair of actuating levers 14 pivoted to a lug on brake shoe 12 are pivoted at 15 to a fixed point on the vehicle; a pair of actuating levers 16 pivoted to a lug on brake shoe 13 have braking force applied in direction P. The auxiliary lever 18 is pivoted at 19 to a fixed point on the vehicle and is also pivoted to brake shoe 13. A brake bridge 17 of variable length is pivoted between lever-pairs 14 and 16 and is shown in section in Fig. 3. A resiliently compressible member 20, Fig. 2, is indicated at 44 in Fig. 3; an abutment 45, Fig. 3, adjustable by screw 46 to vary its clearance, 48, from member 44, is carried by lever 18 but is not shown in Fig. 2. In operation, when the shoe linings are worn, abutment 45 engages member or plunger 44 on application of the brake; plunger 44 is integral with sleeve portion 32a which through stop ring 35 compresses a spring 33. Stop ring 35 is now out of contact with an adjusting nut 41, and this adjusting nut is now rotated along screwthreaded portion 36 of a shaft 30 leftwards by a helical torsion spring 42, until it again abuts stop ring 35. This sequence takes place while the brake is being applied. When the braking force is released, abutment 45 on auxiliary lever 18 remains momentarily in contact with plunger 44, and casing 31 and bearing bush 39 are moved along shaft 30 by compression spring 33 towards levers 14. The radial flange of bearing bush 39 is thus moved out of contact with a retaining nut 38, and this nut 38 is now rotated along screw-threaded portion 36 leftwards by another helical torsion spring 40 until it again abuts the radial flange of bearing bush 39. The overall length of the brake bridge is thus reduced. A stop 34 retains the plunger assembly at the right-hand end. When the brake shoe linings are replaced, the brake bridge may be lengthened again by rotating bearing bush 39 and with it retaining nut 38. The auxiliary lever 18, instead of being mounted on pivot 19, may be mounted on pivot 15 on which levers 14 are mounted.

Abstract: 1,257,703. Mounting electrical equipment. TELEMECCANICA ELETTRICA OFFICINE MECCANICHE RIUNITE S.p.A. 21 Jan., 1969 [22 Jan., 1968], No. 3281/69. Heading H1R. In an electrical component assembly components are mounted inside a U-shaped metal sheet frame member 4 and the frame 4 plugs into panel 1 provided with two lateral projections 15, two hook members 14 pivotally mounted on the side portions of the U-shaped frame 4 moving into and out of engagement with the projection 15 to retain the frame member in position. The lower face of the frame member 4 carries an undecal plug 3 and four rubber buffers 10 and the panel 1 is provided with a socket 2. When the frame 4 is mounted on the panel 1 plug 3 engages socket 2 and the hook portions 14 are swung downwardly by means of a handle 16 until they engage beneath the projections 15, such that the rubber buffers 10 engage the upper face of panel 1 and are compressed. The arms of the U-shaped frame are bridged by a printed circuit board 5, Fig. 3 (not shown), and also carry elements of a relay. The frame and assembly are enclosed in a casing 9.
