Title: Improvements in or relating to mechanism for feeding articles of sheet material
IPC: A43D83/00
Filed: 1920-09-08
Abstract: 172,578. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Sept. 8, 1920. Pile supports; sheet separators.-Flat articles such as heel lifts are separated from a stack held by supporting-members at separated marginal portions in a magazine with an open end by causing the endmost article to pass by said supports by successively moving the article in opposite directions relatively to the stack and also to the supporting members, the movements being in the plane of the articles, and the article being released to move in a direction transverse to this plane. As shown a stack of heel lifts 8, which are of the kind described in Specification 186,076 are supported in a magazine 26 on a fixed support 82, and a pair of supports 86 adjustably secured to a bracket 14 on which the magazine is mounted. The lifts 8 are positioned by an adjustable curved member 28 engaging their rear ends, and by a pair of members 40 engaging the breast corners of the heels, the members 40 being adjustable laterally by a rightend left hand screw 50, and longitudinally by a screw 54. The magazine is adjustable relatively to the support 14 by a bolt 32, and nut 34, and calipering-members 126, 128 are provided to enable the magazine to be adjusted so that its bottom edge is spaced above the supports 82, 86 by a distance equal to the thickness of a lift. The bottom lift is separated and caused to drop on to a transverse conveyer 124 by the action of a pair of pushers 88, 98, which are operated for movement in the same direction by means of racks engaged by oscillating segmental gears 94, 114 connected by a link 120 and operated by a connecting-rod 122. As the pusher 88 moves to the right it moves the bottom lift off its support 82 and forces it up the supports 86. On the return movement, the pusher 98 moves it off the support 86 and it falls on to the conveyer 124. The magazine is fitted with a pair of pivoted doors which are normally held closed by spring-catches against the action of springs which tend to open the doors. The supply of lifts is renewed by opening these doors. The support 14 can be detached from its pivot 12 on the base 10, but it is normally held in position by a clamping-bolt.

Title: Improvements in or relating to railway signalling apparatus
IPC: B61L3/02
Filed: 1934-05-16
Abstract: 416,652. Track apparatus for actuating signals on trains and for controlling trains. BROOKER, A. W., 192, Waverley Road, Reading, Berkshire, and TYER & CO., Ltd., Ashwin Street, Dalston, London. May 16,1934, No. 14796. [Class 105.] Two unequally spring-loaded members are engaged by a member moved by a mechanical action arising at a fixed track ramp, the more lightly loaded member being displaced to actuate a signal providing that it is not locked by a magnet which is controlled by the electrical condition of the ramp. If the lightly loaded member is locked then the more heavily loaded member is displaced and effects a brake application. The ramp r rocks a ever e<4> having a Bowden wire connection to a spring drum a which is formed with a cam c engaging a roller on a pivoted lever f. The lever f projects a roller f<2> between rollers g<3>, h<1> respectively carried by a lightly spring-pressed slide g and a valve actuating lever h. The slide g is locked by a detent i<2> so long as the magnet i is de-energized, the detent being forced into locking engagement during downward movement of the slide g by an incline g<1> engaging the remote end i<3> of the pivoted detent i2. With an energized ramp the slide g is raised by the forward movement of the roller f<2> since as the slide rises slightly the detent i2 is removed by the magnet i. The slide g<1> on rising is adapted to rock a lever j, whereby a detent k<1> carried on a notched wheel k is caused to engage the drum a so that the wheel k is moved by the drum ; the notches actuate a bell striker l<1>. With a de-energized ramp the slide g<1> remains locked by the detent i<2> and the forward movement of the roller f <2> therefore actuates the valve lever h against the stronger pressure of the valve spring; the valve is maintained open until the latch h<2> is removed by hand. The Bowden wire has an insulated inner sheath e<3> for the electrical connection. Fig. 4 shows a secondary valve n held closed by an arm p to which is attached one end of the spring of the drum a. The arm drops on mechanical failure of the apparatus and also descends at each ramp actuation by reason of the free end of the lever f engaging a slope p<1> on the arm p.
