Abstract: 498,392. Shoe - trimming machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., BRAY, W. N., and LANE, H. (United Shoe Machinery Corporation, [in part]) July 6, 1937, Nos. 18723 and 23744. [Class 17 (i)] Relates to machines for trimming the inner Layers of a pulled-over shoe upper so that the outer layer may contact direct with the insole when lasted in a bed-lasting machine, and consists in machines provided with a power driven reciprocating knife co-operating with a shear member formed on a finger arranged to extend between the outer and inner layers of the upper. The shoe is positioned against an insole gauge and is traversed by the operator. In one form, a knife 7 is carried by a slide 3 axially reciprocated rapidly by an eccentric. An insole engaging foot 15 determines the position of the shoe. The knife has an edge inclined to its path of movement and has sliding engagement with a shear member carried by a pair of arms 11. A separator blade 23 is rocked by the knife carrier to carry the outer layer 115 well out of the path of the knife. The dimensions of the shear member are such as to mask the point of the knife throughout its travel. A plough 21 extends in the opposite direction to that of feed, from the foot 15. In a modification, the work is positively fed by a pair of tapered rolls 145, 146, the first of which is fixed and the second movable about a pivot 155 to allow insertion of work. The rolls are driven by a belt 161 tensioned by a spring 168 secured to a bellcrank lever carrying a jockey pulley 163, a link 156 actuated by a treadle rod 160 pressing the movable roll against the work. The knife 118 co-operates with a shear member 138 above it. Below the knife is an insole-engaging member 142. Both these latter members are adjustably carried by the machine frame. The shank of the knife carrier engages an inclined slot in the reciprocated bar 120, so that shortening of the blade by grinding can be compensated by adjustment.

In a rear view vehicle driving mirror having a head 22 which can present images of different brightness according to the angle at which the reflected light is observed and an arm 10 secured to a base-plate 11 by means 12, 13 permitting the arm to break away under impact, a carrier 17 pivotably mounted at 20, 21 on flanges 15, 15, of a channel section end portion 14 of the arm 10 adjustably mounts the head 22 by a dome and socket joint, and a member 37 having a finger grip 38 and including a helical groove 40 engaging a lug 43 on the carrier is pivoted on the portion 14 so that the carrier may be moved to either one of two limiting positions defined by engagement of the grip 38 and the corresponding flange 15. A spring 45 urges the carrier to one of the limiting positions. The carrier pivot 20, 21, the dome and socket joint, and the point of engagement between the member 37 and carrier 17 may occur in any order along the carrier. The means 12, 13 is described particularly in Specification 1,196,266. In a modification, Figs. 3, 4 (not shown), the relative dimensions and shapes of the arm and carrier are altered so that the carrier acts as an arm for the mirror head and the arm is reduced to a bracket plate secured to the base-plate and having the carrier arm and manually operable member pivotably secured thereon. In another embodiment, Fig. 6, a toggle linkage is formed by a leaf spring 66 engaging in slots 65 in each flange of each of a channel shaped carrier and a manually operable channel member to give an over-centre snapping movement limited by engagement between the surface of the spring and the appropriate sides of the slots 65. In a modification, Figs. 7, 8 (not shown), a bar across the end of the manual member engages in a parallel side slot in the carrier against the action of a spring, to give an overcentre movement limited by engagement of the appropriate end of the carrier with the web of the channel in the arm.

Abstract: 650,509. Automatic circuit-breakers; protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. July 15, 1948, No. 19042. Convention date, July 18, 1947. [Class 38(v)] Each of a number of feeders connected to a supply line has a branch circuitbreaker, these breakers being connected in series with a main automatically-reclosing breaker, which is opened on fault before the breaker in the faulty feeder is opened, the main breaker then reclosing to restore the supply to the sound feeders. Each branch breaker comprises a tube 21 carrying a movable contact 32 normally engaging a contact 17 and latching contacts 19, the tube being carried in a projection 25 of a cover 20 which also carries a metal frame 23 supporting the lower end of the tube. The frame 23 is pivoted at 26 between the forked ends of a lever 27 pivoted at 29 and carrying a spring-urged contact 30 adapted to engage a fixed contact 13. The cover 20 also carries the core 34 of a tripping magnet 22, the coil 33 of which is connected in series with contacts 30, 32, by leads 39, 40, respectively. An arm 38 fixed to lever 27 has an aperture 43 normally engaged by a lug 42 on a latch 37 pivoted at 44 and urged counter-clockwise by a spring 45, Fig. 7. On an overload, the main breaker and the breaker in the faulty feeder are energized, the armature 36 of the latter moving upwards to disengage the arm 38 from latch 37 which is then moved away by spring 45, the arm 38 being held up by a lip 48 on the armature. When the main breaker opens, the armature 36 drops and releases the arm 38, whereupon the cover 20, magnet 22, tube 21 and lever 27 swing counter-clockwise about pivot 29 to separate the contacts. The breaker is reset by re-engaging the lug 42 and hole 43, and swinging the cover into position by hand. In a modification, Fig. 8, the upward movement of the armature is delayed by a piston 52 acting in a cylinder 51, the air in which has to be expelled through an adjustable orifice 55. The downward movement is unrestricted because of a flap valve 58 on the piston. The modified breaker is stated to be suitable for use in the protective arrangement. of Specification 650,510, wherein the main breaker opens at least once rapidly and eventually in a delayed manner, the dashpot 51 ensuring that the branch breaker does not open before the delayed opening of the main breaker.
