Abstract: A locking differential has a fixed drive dog and a movable drive dog. A locking actuator has a plunger drivingly connected to the movable drive dog. The plunger is movable in a first direction to a lock position in which the drive dogs are engaged and in a second, opposite direction to an unlock position in which the drive dogs are disengaged. A piston is connected to the plunger and disposed in a cavity in a housing. Movement of the piston in the second direction is imparted to the plunger when the plunger is in the lock position but the piston is movable independently relative to the plunger in the first direction when the plunger is in the unlock position. A pressurized fluid causes the piston, and thereby the plunger, to move in the second direction. A piston bias member biases the piston in the first direction, and a plunger bias member biases the plunger in the first direction. A related method of locking the differential is also disclosed.

Abstract: An undercarriage of a belted or track-type machine includes a drive wheel rotatably mounted to the machine and a roller frame assembly pivotally mounted to the machine. The roller frame assembly includes at least one idler wheel and a number of guide rollers. Stationary shafts are mounted to the roller frame assembly and rotationally support the idler wheel and guide rollers. Mounting caps clamp the stationary shafts to the roller frame assembly. One or more fasteners fasten an end portion adjacent to the shaft engaging portion of the mounting cap in abutting contact with the roller frame assembly. A single fastener fastens the other end portion of the mounting cap to the roller frame assembly; however, the other end portion is spaced apart from the roller frame assembly. The abutting contact between the mounting cap and roller frame assembly minimizes flexure of the fasteners and movement of the shaft under moment loading.

Abstract: A liner for a body such as of an off-highway truck protects the body from wear. The liner has a plate with openings through the plate arranged in a preselected pattern. The plate is of a size to fit a particular portion of the body and is typically removably fastened to the body. The openings in the plate cause material to tumble, instead of to slide, when being removed from the truck. The tumbling action, and the thickness of the plate, reduces wear on the body during material dumping.

Abstract: The frames of many construction machines comprise a complex compilation of fabricated sections or massive cast members that are not necessarily intended to handle a specific type of loading applied to the frame assembly. The present invention provides a frame construction that includes a pair of laterally spaced plate members. Each plate member has a first end portion constructed of a substantially solid plate. A second end portion of the plate members define at least one opening that provides an integral portion of a beam assembly. The first end portion is positioned in the frame construction to accommodate a first type of loading, while the second end portion is located in an area to accommodate a second type of loading.

Abstract: In the manufacture of certain stators for dynamoelectric devices, proper spacing between oppositely-facing winding forms of a winding form assembly is determined by the length of a pair of connector rods extending from one winding form to the other. A winding form assembly can be quickly and easily adjusted for use in the manufacture of stators having various stack heights by removal and replacement of the winding form connector rods with connector rods of an appropriate length. The connector rods are locked to one of the winding forms when the connector rods are in a first rotary position and are removable when the connector rods are in a second rotary position. A simple tool can be used to rotate the connector rods between the first rotary position and the second rotary position.

Abstract: A vapor recovery hose assembly for connecting a liquid fuel dispensing pump to a liquid fuel dispensing nozzle includes a venturi pump for aspirating liquid fuel condensates from the vapor recovery passageway capable of useful operation over a wide range of the liquid fuel flow rates. At relatively low flow rates, all of the liquid fuel passes through the throat of a venturi tube located within the pump. As the flow rates increase, increasing amounts of the liquid fuel are bypassed around the venturi throat. In a preferred embodiment, the liquid fuel which bypasses the throat of the venturi tube flows through the bore of a hollow, bypass tube that partly surrounds the venturi tube and is spring-biased toward the upstream end of the venturi tube.

Abstract: An under-the-cabinet appliance includes a housing for operating parts of the appliance having a front wall, a rear wall, and a pair of side walls. Each sidewall has an outwardly-opening groove extending from the front wall toward the rear wall. Each groove also has a forward end opening to the front wall. A mounting bracket has a pair of bracket arms having mutually-confronting support rails that project from the bracket arms. The support rails are configured to be slidably received by the grooves so that the housing may be assembled on the mounting bracket by orienting the housing so that the forward ends of the grooves are aligned with rearward ends of the rails and then moving the housing forwardly relative to the mounting bracket. To facilitate assembly, the rails and grooves are tapered so that they decrease in height from their forward ends to their rearward ends.

Abstract: A stator support assembly for use during the manufacture of electric motor stator assemblies includes a pallet, a rotatable stator support nest mounted on the pallet, and a lock arrangement that resists rotation of the nest from plural, locked, rotary orientations. The nest has generally horizontal, upwardly-facing, stator core supporting surfaces and generally vertical stator core confining wall portions. Accordingly, a stator assembly being manufactured is supported in a substantially fixed position or orientation as required when a stator assembly is being transferred from one workstation to the next but can be manually rotated from one locked position to the next for the convenience of a human operator when manual operations on the stator assembly are performed. Lock arrangements that may be used comprise recesses and one or more cooperating spring-biased detents or, alternatively, holes and a spring-biased shot pin.

Abstract: Stator coils having lead wires inserted into temporary wire clamps at a winding station are electrically tested before the coil lead wires are removed from the temporary clamps. The clamps each include a jaw formed with a wire-engaging surface which scrapes the insulting coating off from a lead wire as it is inserted therein. The clamps are mounted on an electrically insulating support and are electrically connected to terminal members which are engageable by electrical test terminal members.

Abstract: A radiant electric space heater is provided with a high heat limiting capillary tube thermostat and with a grill which is pivotally mounted so that it may be pivoted to an out-of-the-way position for cleaning. The capillary tube thermostat extends along a wire forming part of the grill and into the housing of the heater.

Abstract: A radiant electric heater has a pair of bracket arms rotatably attached to opposite ends of a housing secured to a support bracket attached to a ceiling over a work space. A control switch mounted on one of the bracket arms and a control knob secured to the switch are substantially centered on the housing's axis of rotation. The housing is rotatable relative to the bracket arms throughout an angle of not more than 90 degrees and can be held in any one of several angular positions. The control knob may have a ball chain attached thereto to control operation of the heater from a position remote from the heater. In a modification, heat shields are provided along the upper and lower margins of a reflector assembly to prevent extreme heat build-up on the heater housing.
