Abstract: 1,030,373. Nut runners. INGERSOLLRAND CO. March 25, 1964 [April 1, 1963; Jan. 6, 1964]. No. 12563/64. Heading B3N. [Also in Division F2] A rotary impact nut runner comprises an air motor 2, Fig. 1 (not shown), a hammer rotor 10 splined to the motor shaft 3, an axially slidable hammer dog 15, keyed to rotor 10, an anvil 18 integral with a drive spindle 6, and a tubular cam 27, splined to dog 15. In operation, rotor 10 and dog 15 are rotated, thus causing cam 27 to rotate, and a lobe 36 on the latter, engages a lobe 38 on an anvil 18, to tighten the unit. When a predetermined torque is reached, lobes 36 and 38, ride over each other and cam 27 moves dog 15 axially through spring 34, thus disengaging teeth 16 and 19, on the dog and anvil respectively. After the lobes are disengaged rotor 10 rotates freely for a full turn, and the speed of rotation increases. The lobes again engage, and due to the increased speed, cam 27 is moved abruptly axially, spring 34 is compressed, but dog 15 lags behind the cam. Teeth 16 and 19 collide, and a rotary impact blow is delivered to socket 8. In a modification, the cam 54, Fig. 9 (not shown), is resiliently mounted in anvil 46, and a cam follower 52 is carried by dog 42. In a further modification, the cam 70, Figs. 12, 13 (not shown), is mounted on the anvil 67 to rotate relative to the anvil, under shock, instead of moving axially as in the embodiment of Fig. 9 (not shown). Cam 70 has a lobe 71 and is located in an annular groove in the anvil. A pair of springs 72 are provided to bias the cam into its normal position, and a follower 73 mounted on dog 63, co-operates with the cam. In a still further modification, the embodiment of Fig. 9 (not shown), has two dog teeth 43 and two anvil teeth 47, and the end of cam 54 has a lobe which extends for a little more than 180 degrees of its circumference.
