Abstract
831,762. Lathe details. SENECA FALLS MACHINE CO. Nov. 7, 1957, No. 34766/57. Class 83 (3). In a machine-tool, a differential connection allows an angular movement of a timing-drum for controlling the speed or direction of carriages &c. to be co-ordinated with the linear movement of a tool carriage, when either singly, or jointly, operated and controlled. The carriage 10 supports mating gears 11, 15, the former being threadably mounted on a lead-screw 12, and the latter on a splined shaft 16, driven through a gear-wheel 27, the rotation of which transmits movement to the carriage, providing the leadscrew 12 is held stationary by a magnetic friction-brake 14. Alternatively the shaft 16 may drive the lead-screw 12 through sprockets 20, 21 and chain 22; the sprocket 20 being connected to shaft 16 by a magnetic clutch 23, the latter being energized when brake 14 is ineffective and vice versa. A timing-drum 30, having a worm-gear 31 engaged by a worm 32 on a shaft 33, is driven at a predetermined speed by either the shaft 16, or the lead-screw 12. The worm-shaft 33 is connected to shaft 16 by sprockets 42, 43, chain 44, shaft 41, sun-wheel 40, planet-pinion 38 and an off-set arm 37 rigid with shaft 33; and the shaft 33 is connected to the lead-screw 12 by sprockets 54, 55 and chain 56, the sprocket 55 being rigid with a differential casing 51 mounted freely on shaft 41 and having internal teeth 50 mating with planet-pinion 32 on arm 37. In use, the slow travel of the carriage is effected with the casing 51 held against rotation by the brake 14, the shaft 16 driving the drum; and fast travel is effected by rotating the lead-screw in addition to the gears 11, 15, the extra movement being conveyed to the drum through sprockets 54, 55, &c.
