Title: New or improved selector mechanism for variable-speed gearing
Inventor: TAYLOR ALEC
IPC: F16H59/04
Filed: 1955-06-23
Abstract: 797,364. Change-speed gear. BROWN & SONS (HUDDERSFIELD), Ltd., D: Sept. 24, 1956 [June 23, 1955], No. 18141/55. Class 80 (2). Ratio selecting and establishing mechanism for a main change-speed gear in series with an auxiliary change-speed gear comprises a manually operated shift lever movable in a gate having multiple establishing slots intersected by a central cross-shift slot, selection and establishment of a new ratio in the auxiliary changespeed gear being effected by appropriate movement of the shift lever along the cross-shift slot to slide a member parallel to the slot, and thereby actuate the ratio establishing means in the auxiliary gear. In one form, a shift lever d, Fig. 1, is integral with a selector arm f and fast with a selector rod a carrying a second selector arm e. The selector fork f is alternatively engageable with three gear shift forks g, h, k slidable on rods g<SP>1</SP>, h<SP>1</SP>, k<SP>1</SP> to establish five forward and one reverse ratio in a main changespeed gear. Movement of the selector rod a and shift lever d rightwards from the position shown in the Figure first actuates an electric switch m to change the ratio in an auxiliary changespeed gear in series with the main change-speed gear, and then slides the selector arm f out of engagement with the selector fork k and engages the selector arm e with the selector fork g. The five forward ratios of the main change-speed gear can then be selected and established by manual operation of the shift lever d while the new ratio is maintained in the auxiliary changespeed gear. A gate n for the shift lever d is provided with the necessary slots to allow the shift lever to establish the ten forward ratios, but is provided with only one slot for the establishment of reverse which is permitted only before actuation of the switch m. In another form, a shift lever o, Fig. 3, is pivoted in two planes at right angles to each other about a ball joint p for manual selection and .establishment of five forward and one reverse ratio in a main changespeed gear controlled by an arm r. By depressing the shift lever o against the bias of a spring t when in its neutral position, a projection u at its end can be engaged in a slot v in a sliding plate w which can then be moved to actuate a switch s. This causes the ratio in an auxiliary change-speed gear in series with the main change-speed gear to be altered, so that by allowing the spring t to disengage the projection u from the slot v, the ratios in the main changespeed gear can be engaged again to give ratios different from those given previously. The auxiliary change-speed gear gives a direct drive and a reduced ratio slightly greater than the entire range of ratios available in the main change-speed gear. As a modification, the establishment of ratios in the auxiliary changespeed gear may be effected hydraulically, pneumatically or mechanically. Further, the main change-speed gear may provide a choice of any number of gear ratios.

Title: Improvements in and relating to cinematographs
IPC: G03B15/08
Filed: 1928-06-25
Abstract: 319,644. Smith, W. June 25, 1928. Kinematograph apparatus. - In kinematograph apparatus of the type in which reversal of the feeding mechanism is automatically produced in the course of travel of the film, a pair of feeders and the film gate are moved relatively to each other so as to bring the film into engagement with the feeder alternately. The invention may be applied to the feeding of a film with the picture series on each side of a central row of apertures, or to a feeding arrangement in which alternate pictures are stepped over in one direction and exhibited on reversal. One arrangement of the apparatus is shown in Fig. 1 and comprises a film gate 34 pivoted on a post 36 and provided with lateral wings making a large obtuse angle with each other, and two feed claws 28, 29 continuously operated in opposite directions by cam-actuated plates 33 driven through gearing from the main shaft. The gate is held in a position to cause one or other of the claws to engage the film by means of a latch, which is carried by a spring controlled lever pivoted on the gate and co-acting with the film to release the latch at the desired time. A slotted arm 35 is thereupon moved by a crank pin 21 on a spring-actuated disc 22 into the alternative position in which the other claw engages the film. Two reels 3, 4, act alternately as winding and un-winding reels and are driven by a flexible belt 14 passing round a pulley 10 on the main shaft and pulleys 12, 13 on a carriage 11 which is pivoted on the shaft and is thrown into position to cause the belt to drive one or other of the reels by a slotted lever 19 actuated by the crank-pin 21 when the reversal of the feed device takes place. Fig. 7 shows another construction in which the feed claws 56 are operated by crank and link connections 57, 58 and slide on an angled member 61 which is held in one or other of its two operative positions by latches the release of which is controlled by the film. The member 61 is thrown over from one position to the other by the spring- controlled crank disc 22 acting on the slotted arm 62. A further modification is described in which one driving device is provided for an angled bracket carrying both feed claws. Means may be provided for laterally shifting the lens or a screen in the condenser or covering the source of illumination, when a film with two sets of pictures side by side is used, and a trigger may be set to stop the action at will, when a clockwork, electric or other motor is used as the prime mover.

Title: Improvements in or relating to an electric stapling machine
Filed: 1957-06-12
Abstract: 848,101. Stapling machines. SWINGLINE Inc. June 12, 1957 [April 22, 1957], No. 18598/57. Class 89(3) In an electric stapling machine generally similar to that described in Specification 823,561, the switch MC, Fig. 17A, is operated by a trigger T, Fig. 8, carried by a pivoted yoke Y having lips 403 which are engagable by the cap CP whereby the trigger T is elevated to actuate the switch by downward displacement of the cap CP only. The trigger T, in moving into the elevated position, engages the actuator 99 of the switch, which energises the solenoid SD, Fig. 3, causing the armature 32 to rise thereby rocking the lever MT which forces the cap CP down to drive a staple. The rear end of the lever MT carries an abutment AB which during the driving stroke of the machine engages the trigger T which is thereby rotated against a spring 412 until the nose N of the trigger T moves clear of the actuator 99, Figs. 17D, E, permitting the contacts of the switch MC to open. The solenoid is thereby de-energised and return movements of the lever MT, cap CP, yoke Y and trigger T reset the machine for driving the next staple, Fig. 17G. The arrangement ensures that one complete operating cycle must be carried through without interruption before the next operating cycle can be initiated. When the cap CP is opened, the spring 412 holds the trigger widely withdrawn from the switch actuator 99, so that in the event of the lever MT being accidentally depressed, the trigger is permitted to idly clear the actuator.
