Title: Improvements in and connected with electric tumbler switches
IPC: H01H23/16
Filed: 1943-09-18
Abstract: 568,435. Tumbler switches. CRABTREE & CO., Ltd., J. A., and MORGAN, R. W. Sept. 18, 1943, Nos. 15367 and 21204. [Class 38 (v)] A tumbler switch having means for imparting a larger angular movement, and increased thrust, to the moving contact to ensure its effective engagement with the fixed contact, comprises an insulating, hollow, contact-rocker d pivoted at c to a U-shaped extension b of the dolly, and a pivot pin k sliding in slots k<1> in the rocker d and in openings i in a fixed, channel-shaped bracket g. When the dolly is rotated about pivot f, a spring l within the rocker d is compressed between pins. c, k until the dead-centre position. is reached, the pin k then moving to the other end of openings i and rotating the rocker about c, so moving the contact still further to the right and providing increased closing thrust. In Fig. 6, the pin k engages holes k<2> in spaced plates p pivoted on the dolly-pivot f, the degree of pivoting being limited by the bridge e.

Title: Improvements in or relating to electrically operated engine starters
IPC: F02N99/00
Filed: 1937-06-03
Abstract: 496,943. Turning-gear. SPERRY GYROSCOPE CO., Ltd., and CLOUSTON, C. E. June 3, 1937, No. 15438. [Class 7 (v)] In an engine starter comprising an electric motor 45, the armature 46 of which is normally displaced axially of the field windings by a spring 32 and on energization is moved axially to effect the engagement of starter clutch members 1, 1<1>, the clutch member 1 is arranged to follow up the member 1<1> if and when the engine overruns the motor. As shown in Fig. 1, the clutch member 1 is mounted on a shaft 62 and has ratchet teeth 26 held in engagement with similar teeth on a member 25 by a spring 35. The member 25 is splined in a sleeve 221 driven from the armature shaft 47 of the motor through splined sleeves 48, 49 and the reduction gearing described in Specification 494,119 with reference to Fig. 3 of the drawings. When the engine starts and overruns the motor, the shaft 62 and the clutch member 1 are driven directly from the armature shaft 46 through a friction clutch 70 which normally slips during the starting operation. The clutch comprises a plate 71 fixed on the shaft 62 and a sliding plate 72 held by a spring 73 in engagement with an interposed cup-shaped member 75 secured to a disc 69 on the shaft 47. In a modification, Fig. 2, the clutch 1 is normally held out of engagement by a detent 76 pivoted at 77 on the motor housing and urged by a spring 78 against an inclined face 79 on the clutch housing 80. The spring 78 yields when the motor is energized and does not tend to throw the clutch 1 out of engagement if the endwise magnetic pull on the motor armature is weakened during the starting operation. The friction clutch 70 comprises metal plates 81 splined on the shaft 62 and gripped between plates 82 splined in the housing 80, which has a screwed end plate 84 forming an abutment for the spring 83. The member 25 of the clutch 1 is journalled in an antifriction bearing 91 and the spring 35 bears against a thrust block 92 in the member 25.

[Class 74 (ii)] To avoid jamming of the thread, a spool 10 is held horizontally by a tapered, split, metal bush 5, expanded by inserting a cone 8, and the yarn is led through a china or like bush 9 arranged in the extension of the spool axis. A bell-shaped cover 2 of smooth transparent material such as glass, protects the spool, and carries in its closed end the bush 9. The cover is secured to a base 1 by straps 3 and its open end is closed by a plate 4 carrying the spool support, and an intermediate rubber packing. The plate 4 is normally locked in position, but may be moved to the left when the spool is to be inserted, by means of guide bars 6, sliding in the base 1.

[Class 51 (ii)] In a furnace particularly for the heat treatment of metals in slab form in which the slabs are passed through the furnace on their edges, the slabs are fed into the furnace at one end by a loading carrier so that they rest on their lower edges, and are then pushed through the furnace towards the discharge end where they are removed by an unloading carrier on to a suitable support, the slabs situated near the discharge end being retained in an erect position. As shown in Figs. 1 and 2, the slabs are supported in the furnace on a pair of endless chains 11 on to which they are lifted at the feed end of the furnace by a pair of U-shape carriers 15 pivoted on the shaft 13. One or more pushers 18 each mounted on a pivoted lever 20 and operated by a pinion 23 and toothed segment 22 advance the slabs in the furnace and at the discharge end each slab is received by a carrier 28 similar to the carrier 15 and deposited on a support 32. The slabs at the discharge end of the furnace pass on to a horizontal or inclined track 26 and those slabs adjacent the end one being discharged are held in an erect position by lever arms 15 having pivoted gripping members 3 with serrated surfaces 35 and pivoted auxiliary supports 36, Fig. 3, operated by the unloading carriers 28. Spacing members 4 are arranged between the slabs.
