Abstract: 513,768. Photographic roll-film cameras. KODAK, Ltd. June 29, 1938, No. 19253. Convention date, July 13, 1937. [Class 98 (i)] A camera back carrying a motor drive unit is removable by operating a latch which at the same time locks the motor against movement. The motor drive unit consisting of a spring motor and camera back is either attached directly to a rollholder camera as described in Specification 513,738, or to a roll film holder which may be removably mounted on a camera as described in Specification 509,026. The flat camera back 10 is curved at its ends 12, 13 to form the walls of a spool chamber and is provided with side flanges 14, one of which carries a hinge element 16 to receive a pintle 19. The camera has a co-operating hinge element '20. The pintle 19 slides through a circular member 22 carried by the bottom wall of the camera back. Axial sliding movement is prevented by a latch 27, which, when engaged, allows the back to be swung open to load and unload film. When it is desired to remove the motor unit, the latch 27 is moved downward to allow the pintle 19 to move axially until a groove 32 at its end is engaged by a spring washer 30. In this position, the hinge elements are free to separate, and the back can be removed if the latch 37 at the opposite edge of the back has been released. This latch comprises an externally projecting member carrying a stud 36 which slides the bar 37 having hooks 38, 39 to engage complementary pins. In the latched position a hook 42 is clear of a toothed wheel 43 so that the motor is free to operate. In the unlatched position, hook 42 engages wheel 43 so that the motor unit may be removed or the back swung open without the motor running down. The shaft of the wheel 43 carries a governor 45, and is connected to the main gear wheel 50 by gearing 47, 49. The film is wound by means of a crown wheel 53 which also operates the shutter setting mechanism which may be of the form described in Specification 513,738. The motor spring is wound by a handle 54 on a shaft 56 carrying a ratchet wheel 57 engaging a ratchet 58 carried by the wheel 50. The shutter, after release and running down, may position the shutter winding and film winding mechanism so that they may, be set for another exposure as in Specification 513,738. A camera having a hinge latch as above may be employed with either a motor drive unit or with the usual camera back or roll film holder back. To provide a record of the number of exposures taken on the film in a back which is removed, a graduated disc 53 may be provided, which may be set to the indication of a film counter on the camera housing, so that when the roll holder is replaced, the film counter may be adjusted to the same graduation as before. If the camera -does not employ a removable roll holder, the addition of the disc 53 is unnecessary. Specification 513,755 also is referred to.
