1329195 Slide projector EASTMAN KODAK CO 18 Nov 1971 [18 Nov 1970] 53635/71 Heading G2A In a slide projector receiving stacked slides 9 there is provided a slide engaging member 2 engageable with the bottom slide 9a and a slide support 1d movable transversely in the direction B with the member 2 so as to remove and then drop the slide 9a. As shown the member 2 is mounted by pivot pin on to a plate 1 carrying support 1d. Transverse movement is caused by the movement of a pin 3 in the direction A and hence to action on the walls of groove 1b. The plate also has a slot la around pins 10 to ensure purely transverse movement. When the pin 3 descends portion a of groove 1b, the plate 1 moves to the left and finger 2c of the member 2 dislodges the bottom slide 9a so that its leading and rests on support 1d, the rear end of the slide 9a being supported by surface 8a of the slide holder 8. When the pin 3 passes through portion b of groove 1b, this rear end is allowed to drop from surface 8a on to surface 4c. Portion c of groove 1b when engaged by the pin 3 causes a second movement of the plate 1 to the left such that the slide 9a is held by stop 4e and when the portion d is engaged the slide 9a may pivot about its rear end and fall under gravity towards a projection gate (not shown). Also during this second movement of the plate 1, finger 2a engages surface 4f so that the member 2 rotates anti-clockwise through an angle α thereby retracting it for the return movement of the plate 1. The member 2 is restored to the position shown in Fig.1 by the abutment of projection 2b and the housing 4 of the projector. As shown a slide holder 8 is provided but this is not essential.
