Abstract: A rotary indexing mechanism for indexing a shaft or shaft mounted member in precise rotary increments and with precise end-of-movement positioning includes a reciprocable rack and pinion mechanism coupled to a rotatably mounted shaft. The pinion is coupled to the shaft through a one-way clutch so that movement of the rack in a first direction is coupled through the clutch to cause a corresponding rotation of the shaft with the clutch uncoupling the shaft during movement of the rack in the opposite direction. A first stop member(s) is carried by the shaft for movement along a path that orbits the shaft axis. A second stop member is carried by the rack along a linear path that intersects the orbit of the first stop member. As the rack rotates the shaft through a rotary increment, the rack-carried second member is positioned in the orbit of the first stop member with the two members engaging to halt further rotary movement.

Abstract: An adjustable intermittent incremental advance system is provided having a rotatable shaft for driving a work take-off in a start-stop rotary incremental advance. A clutch disk and brake disk alternately permit or stop rotary motion of the shaft to provide the intermittent advance. A flywheel is attached to the rotary shaft and acts through a crank arm driven by a motor to provide rotary power to the shaft for predetermined incremental movement. First and second sensors provide timed application of the clutch and brake disks to provide accurate incremental advance and prevent accumulated error in length of advance during prescribed periods of operation of the system.
Abstract: Apparatus for performing machining operations on a workpiece or detail at different angles, comprising a rotatable table having a plurality of locating holes preferably spaced at one degree intervals about its periphery, two indexing pins insertable in the holes, and two indexing blocks having prongs provided with abutment surfaces in positions to be contacted by the pins. The table normally rests upon pads during a machining operation. To rotate the table to a new position, the table is lifted from the pads by a manually operable lifting mechanism. Anti-friction rollers support the table when raised to facilitate rotation.
Abstract: A machine tool wherein an annular gear is rotatable in a horizontal plane to carry a plurality of pallets between adjacent peripherally arranged machine stations. The gear is lowered as each machine station is attained by the entry of gear support bearings into recesses in the underside of the gear. The pallets are supported on the gear for limited vertical and horizontal movement, and lowering of the gear positions the pallet on an abutment surface in alignment with the machining station. As the gear is further lowered, it is spaced from the pallet so as not to interfere with independent positioning of the pallet by any power actuated positioning means located at each machining station. Thus, the pallet can be adjusted independently of the gear when the gear is in its lowered position, yet is carried by the gear when the gear is in its elevated position.
Abstract: A fixture for indexing a work piece, a machine spindle, or the like permits indexing a single rotation of the work piece or other mechanism in any integral number of equal divisions. Stops for the divisions are made to suit the job by assembling a standard roller chain with as many pins and pin spaces as there are to be divisions and mounting the chain about a tapered body, preferably a cone. Fixtures hold the chain at the plane in which the periphery of the cone is the right diameter to receive the chain and other parts adjust the indexing stop to overlie the roller chain at that plane. Adjustments are provided to adjust the indexing stop peripherally of the cone a short distance in order to bring the indexing stop to the required rotational position. This adjustment may also be used to adjust the rotatable part a fraction of an indexing stop.
Abstract: A change-speed gearbox has coaxial input and output shafts. Five intermediate shafts are equi-spaced around the input shaft and each has two gears fixed thereto, one of which meshes with a common gear on the input shaft, the intermediate shafts being movable axially.Five gears of different diameters are fixed to the output shaft around which five secondary shafts are carried by a rotatable cage. The five secondary shafts each have two gears fixed thereto, one of which meshes with a different one of the gears on the output shaft.Any one of a possible twenty five gear ratios between the input and output shafts may be obtained by rotating the cage until a selected one of the secondary shafts is in the same radial plane as a selected one of the intermediate shafts, that intermediate shaft then being moved axially to bring the second gear thereon into mesh with the second gear on the selected secondary shaft.
