A vehicle drive system including a wheel (16) to be driven, a suspension (18) having multiple relatively movable parts (24,26,28) and mounting the wheel for rotation and translation on a vehicle frame, a hydraulic rotary output motor (12) connected to the wheel for driving the wheel, a hydraulic pump (10) providing hydraulic fluid under pressure to the motor, a conduit (50) interconnecting the pump and the motor, and a flow control valve (40) in the conduit for controlling the flow. A switch (90...

A scraper bowl structure (11) for use in a scraper vehicle (10) having a rear wheeled support (12) and a wheeled tractive unit (15). The bowl structure (11) is defined by sidewalls (16,17) pivotally mounting a front apron (22) and a rear blade (25). Positioning devices (29,30) are associated with the apron (22) and blade (25), respectively, selectively positioning the apron (22) and blade (25) in raised and lowered positions. Spreader elements (19,20,21) for securing the sidewalls in spaced rela...

In a machine for covering a toroidal body with layers of elastomeric material wherein a cutting and stitching apparatus is provided for severing a scrap portion of a sheet of material (32) from a portion of the sheet that has been applied to a toroidal core (30) and stitching the applied portion to the core (30). The apparatus (16,18,20,22) includes actuators (45,54) for positioning the cutters (104) and the stitchers (105) in operative position on the outside periphery and the inside periphery ...

A shuttle driving assembly (10) including an open shuttle (22) rotatably driven on an automatically opened support frame (16) by a plurality of drive roller assemblies (85,87) carried by the frame (16). Each drive roller assembly (85,87) has a drive roller pulley (84) and at least one with plural belts (192,191,190,188,186) driving groups of the drive roller assemblies. The drive rollers contact a groove (115) on the shuttle (22) to provide a positive and responsive power transmission therebetwe...

A tape-applying apparatus (10) is advanced toward a body (15) upon which a strip of tape (16) is to be applied to urge a plurality of stitching rollers (72,74) against the body (15). Further advancing of the apparatus (10) will move an applicator roller (42) and the end of the tape (16) into engagement with the body (15). As the body (15) is moved past the tape-applying apparatus (10), the tape (16) is pulled over the applicator roller (42) and is stitched to the body (15) by the stitching rolle...

A balancing mechanism in a conventional, multicylinder engine consisting of a mass linked to the static portion of the engine and dynamically linked to the engine crankshaft in such a manner as to establish an arcuate oscillation of the mass on rotation of the crankshaft for producing a primary harmonic shaking force and a secondary harmonic shaking force in the direction of greatest travel of the mass, and a secondary harmonic shaking force in a direction at right angles to said first-mentioned...

An appliance control console structure adapted to be mounted on a mounting portion of the appliance for suitably housing the appliance electrical controls. The structure includes a pair of end cap assemblies, a mounting plate extending between the end cap assemblies and carrying the electrical controls, and a cover. The end cap assemblies may be formed of two portions with the portion of the space within the console structure in which the electrical controls are disposed being confronted by only...

An earth working apparatus having a ripper for loosening earth and the like. An impact member is associated with the ripper to provide a cushioned transfer of impact force for improved earth working operation.

A proximity sensor oscillator, having a resonant circuit in which the power loss is inversely related to the distance of a conductive body from a probe containing a part of the resonant circuit, produces an oscillating output signal in the resonant circuit with a peak amplitude that varies with power loss and distance. A power source provides either the current or the voltage component of electrical power at a substantially constant value independent of changes of resonant circuit power loss and...

Apparatus for indicating a clogged condition of a fluid filter or the like. The apparatus includes an electrical switch structure and a pressure-responsive element carried within the chamber to be responsive to the fluid pressure differential existing across the filter. The switch includes a threaded screw element adapted to adjustably engage the fluid pressure-responsive element in the chamber which may comprise a snap action element providing a positive instantaneous indication of the pressure...
