Filed: 1974-10-11
Abstract: 1483407 Photographic cameras EASTMAN KODAK CO 11 Oct 1974 [12 Oct 1973] 44109/74 Heading G2A A photographic camera 10 with an exposure aperture 11, and an apertured shutter blade 36 which, when released by a member 40, moves across the aperture 11 to a final position, has means 50 for resetting the shutter and winding the film, and means for capping the shutter during resetting. As in Specification 44108/72, the diaphragm is set according to ambient light by relatively slidable plates (14), (16), with co-operating apertures (14a), (16a) and (14b), (16b), Fig. 1 (not shown). The shutter blade 17 is slidable in guides 18, 20 between a reset position (dotted lines) in which it is held by a catch 43 on a spring-biased lever 41. It is released by depressing a release 45, whereupon the shutter blade moves to the left to its full-line position under action of a spring 38 until it reaches a stop 46, and the aperture 47 in the blade passes over the aperture 11 to expose the film. The shutter is reset by a slidable reset member 50 and a shield 51, which has a finger 53 engaging a socket 56 in member 50, a straight edge in contact with a pin 62 on shutter blade 36, and a bent over lug 52. During the first part of the movement of resetting member 50, shield 51 moves from the position shown in Fig. 2 to that shown in Fig. 4, in which shield 51 covers aperture 47 and lug 52 engages the edge of blade 36. During the next part of the movement, aperture 47 crosses aperture 11, but is masked by shield 51, and blade 36 moves to the right to its reset position, engaging the catch 43, as shown in Fig. 5. A fixed pin 61 engages a cam surface 60 on shield 51 to tilt the shield so that finger 51 comes out of socket 56 and rides on a level surface of member 50. Member 50 can therefore travel on, driving a film winding mechanism of known kind which allows for the increase in diameter of the film take-up roll. Member 50 is returned (as by spring action) and the camera is ready for a new exposure, as shown in Fig. 2 (full lines).

Title: Winding machine for the rapid, automatic production of unsupported coils of non-insulated or insulated metal wire
IPC: B21F3/04
Filed: 1960-12-30
Abstract: 921,970. Coiling. G. CAMARDELLA. Dec. 30, 1960 [Dec. 31, 1959], No. 44804/60. Class 83 (4). A machine for winding wire coils comprises a mandrel, on which the wire is wound, rotated alternately in opposite directions under control of cam mechanism which also controls the displacement of the wire parallel to the mandrel to control the winding pitch, shears for severing the wound coils from the supply and means for opening and closing a gripper to hold the wire end to the mandrel. In operation a spindle 16<SP>1</SP> carrying a mandrel 51 is first rotated in one direction by a cam 5 on a shaft 2 engaging a roller 6 on a segment 8 to rock the segment and rotate a pinion 10, secured to a gear-wheel 12 and drum 11, the gear-wheel 12 in turn rotating the spindle 16<SP>1</SP>. During this rotation the drum 11 winds a wire 13 thereon to tension a spring 14. At the same time wire 28 is fed to the mandrel 51 by a pawl 27<SP>1</SP> on an arm 24 carrying a wire guide 25 and moved, through levers 20, 22-by a cam 19 on the shaft 2. A cam 35 on the shaft 2 then moves a linkage 36, 38, 40 to open a gripper 43 at the end of mandrel 51 and to release a rod 29 to allow a spring 23 to move the arm 24 up to present the wire 28 to the closing gripper 43. The cam 5 then allows the spring 14 to rotate the spindle 16<SP>1</SP> to wind the wire 28 on to the mandrel 51 until the segment 8 abuts a stop. During this winding a nut 18 on a threaded extension 17 of the pinion 10 moves a lever 30 to move a push-rod 29 which moves the arm 24 to move the wire guide 25 along the mandrel 51 to lay the wire therealong. After winding the spindle 16<SP>1</SP> stops and the wire guide 25 moves back until the lever 22 abuts a stop 26. A cam 50 on the shaft 2 then rotates a rod 48 to cause a knife blade 49 to sever the wire 28 from its supply. The gripper 43 is then opened so that the coil drops off the mandrel 51 on to a needle 52 where it is immersed in gluing liquid. A cam 56 on the shaft 2 later rocks a lever 53 to lift the needle 52 and discharge the coil on to a rotating collecting surface 57. Alternatively, when gluing is not necessary, the needle 52 may be replaced by projections on the periphery of a rotating disc. The spindle 16<SP>1</SP> may be mounted in an eccentric bush, Fig. 2 (not shown) and adjustable so that right- or lefthand coils may be wound. Straightening.-The wire 28 for the coil is unwound from a roller 61 to pass over a tensioning roller 64 and then through a straightening device comprising flexible plastic blocks 68, 69 formed with co-operating transverse teeth.
