Title: Automatic adjuster for shoe drum brakes
IPC: F16D65/56
Filed: 1965-02-04
Abstract: An automatic adjuster of an internal shoe drum brake is mounted between the adjacent ends of two shoes 10, 11 which are carried on a back plate 13 and which have an expander 14 and an anchor 15 between the opposite pair of shoe ends. The adjuster comprises a shoe-engaging tappet 16 threadedly-interconnected with a sleeve 18 which is rotatably mounted on an end plug 19 engaging the other shoe 11 and which carries a peripherallytoothed disc 22 adapted to be engaged by one arm of a bell-crank lever 27 fulcrumed on an abutment 26 punched in a bracket 25 carried by the plug 19. The other arm of said lever engages a stop hole 28 formed in an open, box-form housing 23 which is secured to the back plate by a spring-loaded bolt 24, Figs. 2, 3 and 4 (not shown), such that limited circumferential movement of the housing relative to the back plate can take place. Assuming brake application on normal forward clockwise rotation of the drum, shoe 10 becomes the leading shoe and moves both circumferentially and radially to apply the secondary shoe 11 through thrust unit 16, 18 and 19 which slides axially of the housing. If the wear on shoe 11 is such that movement of said members exceeds a clearance 29 between the toothed disc and the forward end of the housing, the housing will be moved circumferentially on the back plate a distance corresponding to said wear. Then, when braking with drum rotation in the opposite direction, i.e. reverse, shoe 11 acts as the primary shoe to move the thrust members axially through the now stationary housing. Lever 27 is pivoted about the housing stop hole 28 as its fulcrum 26 moves axially and is urged against the bias of spring 31 into engagement with the toothed-disc to extend the effect length of members 16, 18 and 19 by an amount equivalent to the wear on the now secondary shoe 10 plus the wear of shoe 11 previously sensed by housing movement effected during normal (clockwise drum rotation) brake application. In a modified embodiment, Fig. 6, the housing comprises a U-shaped spring member 38 slotted at 40 to permit limited circumferential movement with respect to a slot-engaging lug of a bracket 42 secured to the back plate. One arm 39 of the U-member is apertured to receive an adjustable thrust unit comprising in part an interengaging threaded sleeve and tappet parts, said aperture permitting movement of the thrust unit in one direction but interlocking the unit and housing in the opposite direction. A cranked lever 45 fulcrums on the housing and has one arm abutting the said housing-securing bracket and the other arm adapted to engage a peripherallytoothed disc for adjusting the effective length of the adjuster. In the normal direction of drum rotation, the adjuster unit moves relative to the housing according to wear on the secondary shoe. Then, on braking in the reverse direction, the housing and adjuster move together in a reverse direction a total distance corresponding to the wear on both shoes, said lever rotating the toothed-disc to take up this wear.

Title: Connections between electrical conductors and carbon bodies and method of making same
IPC: B23K35/26
Filed: 1967-12-23
Abstract: Contact resistance between engaged threaded portions of a conductor bar 6, e.g. of copper, aluminium, steel or carbon and a carbon body in the form of a graphite plate or pins 3, is lessened by interposing between the threads a molten alloy 4 of the kind which expands on solidification and which has a melting-point between 95 and 300 C. The conductor 6 is mechanically and/or chemically cleaned and the threaded recess of the carbon body is cleaned by compressed air. The molten alloy is poured in the recess of the body 3, which is heated above the melting-point of the alloy and the bar 6 is threaded into the recess so that the molten alloy rises between the threads. Alternatively, pellets or powder of the alloy may be deposited at the bottom of the recess and the temperature of the assembly is raised above the said melting-point. When the carbon body is a plate, the areas adjacent to the recess are reinforced with graphite or carbon strips or by a thick layer of material left during machining. The end 5 of the carbon body in use is connected to an anode plate of an electrolytic cell, e.g. a mercury-cathode chloroalkali cell. Alternatively, a carbon pin may be externally threaded for engagement in a threaded recess in a conductor body. Examples of suitable alloys are: 58 Bi, 42 Sn 55À5 Bi, 44À5 Pb 48 Bi, 28À5 Pb, 14À5 Sn, 9 Sb 15 Sb, 58 Pb, 26 Sn, 1 Cu 15 Sb, 82 Pb, 3 Sn.
