Abstract: 1,239,149. Rolling gears. MICHIGAN TOOL CO. 27 March, 1969 [29 March, 1968], No. 16110/69. Heading B3M. The teeth on a gear 46 are successively rolled by an oscillating tool 42, the angle between the two flanks of a tooth being bisected by a plane perpendicular to the axis of movement of the tool. The gear, which may be a hypoid gear, has its tooth flanks formed at an angle of other than 90 degrees from a surface of revolution passing through the tooth roots or from a tangent to such a surface. The tool is carried in a driving head 38, and the gear is mounted on a vertically adjustable support 36. Between each oscillation of the tool, the gear is indexed by one tooth. The tool 42 is carried eccentrically on a shaft 48 which is oscillated by a crank 50. The tool performs a rolling motion by the co-operation of a gear sector 52 with a fixed ring gear 54. A slight degree of sliding between the tool and blank can be used to obtain a burnishing action. A common drive is used for oscillating the tool and indexing the gear. Rotation of a cam 118 causes rotation of a ring gear 110, and hence of the blank. An indexing pin, driven by a rotatable cam 124, ensures precise indexing movements by its co-operation with a chuck ring 82. The gear is clamped in position by an hydraulic piston (Fig. 10, not shown).

Abstract: 1296899 Photographic cameras EASTMAN KODAK CO 4 Dec 1970 [4 Dec 1969] 57747/70 Heading G2A A photographic camera having a rotatable socket 11 for sequentially locating flash-bulbs of a multi-lamp percussion-ignited flash-unit (as shown, a flash-cube) at a firing site is provided with a shutter driver 33 movable from a first position (solid lines) to a second position (dotted lines) to actuate a shutter 6; an actuator bar 14 movable from a retracted, cocked position (solid lines) to an extended position (dotted lines) for releasing the striker of a bulb at the firing site; and means responsive to movement of the driver 33 to its second position for moving the bar 14 from its solid line position to its extended position and back again. If no flash-unit is mounted on the camera, a disabling latch 62 constrains the bar 14 to remain in its cocked position despite movement of the driver 33 which frees a first latch 43 from contact with the bar 14. The driver 33 continues moving to engage a second latch 51 thereby releasing a  retracting member 21 which is urged by a spring  27 into its retract (dotted line) position. Insertion of a flash-unit depresses a pin 13.thereby  rotating the disabling latch 62 out of contact with the bar 14. Thus when.the driver frees the first latch 43, the bar 14 rises to its extended position. Release of the second latch 51 and of the retracting member 21 now causes the bar 14 to be returned to its cocked position, as arm 23.engages an.extension 17 of the bar 14 which is thereby depressed. The driver 33 and retracting member' 21 are returned to their solid line positions by the operation of a cocking member 58. In another embodiment, Fig.2 (not shown) the first latch 43 is assembled in two pieces.
