Title: Photographic pivoted blade lens shutter with flashlight synchronizer
IPC: G03B9/22
Filed: 1952-03-13
Abstract: 708,317. Photographic shutters including flashlamp synchronizers. DECKEL, H., and DECKEL, F. W. March 13, 1952 [July 20, 1951], No. 6554/52. Class 98(1) A pivoted blade shutter with a settable blade master member and a settable flashlight synchronizer having a separate source of driving power is characterized in that the synchronizer has a setting arm the setting of which simultaneously sets the master member and in that the synchronizer and master member are held set by separate latches, the synchronizer latch being releasable manually while the master member latch is released by a part of the synchronizer at the end of its run-off. As shown, the shutter master ring 12 and the retard mechanism of the flashlight synchronizer are set simultaneously by anticlockwise movement of the pivoted setting lever 36, a pin 44 thereon moving the ring 12 anticlockwise to be latched in its set position by a shoulder 22 on a pivoted pawl 18 engaging a shoulder 24 on the ring, while the lever 36 itself tensions the driving spring 32 for the synchronizer, the lever being latched in the set position by the pawl 40 on the trigger 41 engaging around the pin 42 on the lever. During setting the gear sector 48 on the lever rotates the retard train and a cam 54 on the star wheel pivot 52 moves a switch lever 62 anticlockwise away from the movable contact 70. On pressing the trigger 41, the lever 36 is freed and rotates so that the cam 54 rotates anticlockwise, moving the switch lever 62 clockwise to close contact 70 on to the fixed insulated contact 72 to complete the flashlamp circuit. As the lever continues its rotation the pin 4 on it pushes the pawl 18 to free the ring 12 and allow the shutter to open. For lamps having no lag a lever 78 is moved to the dotted position when the lever 62 is swung clear of the cam 54. Synchronization is then effected by a pin 82 on a bell crank lever rotated by the blade ring 12 engaging the contact 70 to close the lamp circuit when the shutter is fully open. In a modification, the setting lever is movable relatively to a separate disc to which the spring 32 is attached, the lever itself being returned to its rest position by a return spring when the disc has been latched in set position. In an alternative form the lever 36 is replaced by a slide, the sector gear 48 being replaced by a rack. Specification 275,462, [Class 98(i)], is referred to.

[Class 60.] Gauges.--Relates to machines for facing or polishing type-bars or like slugs of the type which comprises a rotatable carrier, having a series of spaced grippers, feeding mechanism at a loading station for the supply of slugs to the grippers, means for closing the grippers at the feeding station and for opening them at the discharge station and a facing or polishing tool, e.g. a grinding-wheel operatively located between these stations and consists in the provision of a slide along which the slugs are moved towards the grippers and a stop which acts in conjunction with a movable end portion of the slide to act as an escapement mechanism and automatically transfer the slugs one by one to the grippers at the correct times. A pedestal 10 carries an electric motor 11 driving, through belt and worm gearing, a drum 12 rotatably mounted on a spindle 13 carrying a stationary cam 14. The drum is octagonal and on each face is mounted a bell-crank lever 17, 18, the arm 17 of which, under the action of a spring 19, grips a slug 52 on the corresponding face, the arm 18 engaging the cam so as to lift the arm 17 to receive a slug from a shoot 20. The slugs are guided in the shoot by contact of their type faces with a plate 30, and at the lower end of the shoot lie in contact with a .stop 21 and over a movable portion 23 attached to a lever 24, which is rocked to lift the portion 23 by a cam 26 rotating with the drum, so that the slug is lifted above the stop 21 and slides into the space between a face of the drum and its arm 17. As the drum rotates the slugs are positioned by contact with a spring-pressed plate 28 and are then gripped by the arms 17. Continued rotation of the drum carries the faces of the slugs across the face of a polishing- wheel 37 carried by the spindle 36 of the motor 11 ; after polishing, the slugs are released and slide into a shoot 38. The wheel 37 is adjustable towards and from the drum, and for this purpose, the motor 11 is slidable on the pedestal by a screw 45 rotatable by a hand-wheel 46, or by a lever 48 to give slow motion ; the screw is locked by a nut 49. In a modification the grippers are formed as radially sliding rods controlled by springs and a fixed cam and provided at their rotor ends with plates that hold the lugs against the faces of the drum.
