Abstract

653,907. Kinematograph intermittent feed mechanisms. COMPAGNIE FRANCAISE HORTSON. April 9, 1948, No. 9980. Convention date, April 17, 1947. [Class 97 (i)] The striker-pin 12 rotates at a multiple of the picture frequency and is reciprocated axially to engage the eight - bladed Maltese cross 2 only at picture frequency. As shown, the striker-pin and the locking disc 11 are carried on a member 5 on an axially slidable shaft driven by 2:1 step-up gearing from the shaft 6. The shaft 4 is reciprocated by a cam 9 engaging a groove 10 in the member 5 so that the pin engages the cross in alternate revolutions of the shaft 4. The diameters of the cam 9 and groove 10 are in the ratio of the gears 7 and 8.
