| Number | Title | Issue Date |
| 4565270 | Friction clutch convertible for either push-type or pull-type disengagement A friction clutch constructed so that it can operate as either a push or a pull type clutch with only a minimal change in parts. The parts for the two types of clutches are interchangeable except for the release levers and release bearings. This simplifie... | 01/21/1986 |
| 4445600 | Self adjusting release mechanism for clutch A self adjusting release mechanism for disengaging a heavy duty friction clutch that is equipped with a clutch brake. As wear occurs on the facing of the clutch disc, portions of the clutch release mechanism are repositioned to compensate for wear without... | 05/01/1984 |
| 4225028 | Self-adjusting release mechanism with adjustment limiting means A friction clutch having a known type of self-adjusting release mechanism is provided with means for preventing adjustments caused by extraneous forces rather than disc wear. In the known mechanism, adjustment is effected by a pair of ring members carried... | 09/30/1980 |
| 4186826 | Torque limiting clutch brake A clutch brake unit suitable for use in conjunction with a heavy duty clutch assembly for retarding the motion of the driven clutch shaft. The unit is actuated by the clutch release mechanism which causes the unit to be compressed between a movable member... | 02/05/1980 |
| 4149437 | Adjustable spindle liner An adjustable support liner for securely holding a workpiece centered in a machine tool that includes an elongated sleeve having a plurality of clamping units mounted therein capable of holding the work centered in the machine in an undistorted posture. E... | 04/17/1979 |
| 4128162 | Vibratory outfeed A vibratory outfeed conveyor has a base, a feed strip resiliently mounted on the base, and a vibrator connected to the feed strip for feeding objects. A mounting bracket extends downward generally perpendicularly from the base, and an upper region of the ... | 12/05/1978 |
| 4068029 | Molded resilient element for vibratory feeder Resilient element material for a vibratory feeder is molded of a resilient plastic resin to have a base and generally upright elements molded integrally with the base and having upper ends that cooperate to support objects being fed vibrationally. The upr... | 01/10/1978 |
| 4050572 | Accumulator and feeder An object accumulator and feeder uses a relatively long path divided into a series of independently operable sections.
