Abstract:
A remote valve control assembly broadly includes a lever assembly, a control plunger operably coupled with the lever assembly, and a case structure having a pair of case halves. The lever assembly includes a lever and a control handle having a detent pin. The case structure includes interior structure presenting a pivot and a plunger channel. The case structure also includes a single position detent slide mounted on one case half, and a double position detent slide on the other case half. The lever is retained in the case structure on the pivot for relative pivotal movement of the lever assembly between forward and aft positions. The detent pin is adapted to engage at least one of the detent slides for retaining the lever assembly in a desired position. The control handle is configured to selectively disengage the detent pin from the detent slides for movement of the lever assembly. The detent pin is shiftable between a single detent position for engaging the single position detent slide, and double detent position for engaging the double position detent slide. As a result, the control assembly may be placed in a single detent mode for retaining the rotating lever in a center position, and a double detent mode for retaining the rotating lever in the forward and aft positions.
Abstract:
A control assembly for mechanically transmitting a signal from a sending unit to a receiving element is provided which enables the receiving unit to respond to shifting of the sending unit for reducing perceived hysteresis losses during shifting. The sending unit includes a wear plate defining a series of positions thereon for engagement by a shiftable control arm. The control arm is connected by a cable to the receiving element which includes an indicator on a mounting member. During initial shifting of the control arm, the wear plate, which is pivotally mounted, is limited in its travel by one or more prongs extending through the wear plate. Further shifting of the control arm moves the cable so that the indicator moves responsively thereto.
Abstract:
A panel mount cable control assembly is provided which is useful with a vehicle having controllable mechanisms such as a throttle and choke of an internal combustion engine. The cable control assembly includes independently actuated shifters operatively connected to respective Bowden cables connected to the controllable mechanisms, which each shifter having a different mode of operation. A first shifter is preferably maintained in a desired position through frictional engagement, while a second shifter operates for a free return though a spring which biases the shifter to an initial position. Both shifters are preferably mounted to substantially enclose a chamber of a housing, and are positioned for side-by-side independent pivotal movement with the shifters in abutment.
Abstract:
An attachment apparatus is provided for attaching an elongated shaft to a structural element, wherein the shaft defines a longitudinal axis, and the structural element includes an opening through the structural element which defines a central axis extending in a direction generally perpendicular to the axis of the shaft. The apparatus includes a helical coil of wire having a central coiled section and opposed end sections protruding from the coiled section, an inner space defined by the coiled section that is sized to grip the shaft and to prevent relative axial movement between the helical coil and the shaft when the coil is mounted on the shaft, and a fastening assembly for fastening the apparatus to the structural element when at least one end section is inserted into the opening. The apparatus is mounted on the elongated shaft by rotating the opposed end sections so that the coiled section unwinds, increasing the diameter of the inner space to a point where it is slightly larger than the cross-sectional diameter of the shaft. The elongated shaft is inserted through the inner space to a desired position relative to the apparatus, and the opposed end sections are rotated so that the coiled section rewinds, decreasing the diameter of the inner space until the shaft is firmly retained through the apparatus. In a preferred embodiment, the fastening assembly includes hook-shaped tips defined by the opposed end sections, and spaced-apart by a distance greater than the diameter of the opening.
Abstract:
A compact, versatile lawnmower control is provided which is especially useful for holding and releasing ground drive and blade clutch cables and which allow connection and removal of the cable end without dismantling the control, allows the optional inclusion of a releasable handle lock, and allow the use of a deadman handle to release two cables at differing release distances. The preferred control includes an operating handle having a tubular body rotatably mounted within a housing; a coupling element rotatably mounted coaxially with the handle body for coupling with a deadman handle; and a holding and releasing means intercoupling the element and the body for holding the handle in a second position when the element is in the operating position and for releasing the handle for shifting to a first position when the element shifts to a relaxed position. Additionally, the preferred control includes means whereby the cable can be connected to and removed from the handle without dismantling the control and means preventing handle movement when released by a manually operated release lever.
Abstract:
A cable control assembly snaps into a control panel of a lawn mower or other piece of equipment to thereby enclose the opening in the control panel into which the assembly is received. The cable control assembly hereof includes a case and a shifter which is engaged by a detent spring, the case including a rim and at least one resilient snap for holding the margin of the control panel surrounding the opening therebetween. The detent spring includes a detent positioned between a pair of divergent arms which engage the case and inhibit transverse movement of the spring in the direction of orientation of the arms during pivotal movement of the shifter.
Abstract:
A dual action cable control apparatus (20) includes a mounting bracket (22), a first Bowden cable assembly (24), a second Bowden cable assembly (26), an elongated lever (28), and a rotatable spool (30) mounted upon one end of the lever. Spool (30) is coupled with cable assembly (24) for shifting the cable to actuate a lawn mower transmission linkage concomitant with rotation of the spool. Lever (28) is operably coupled with cable (26) for actuation of a lawn mower drive engagement control linkage concomitant with rocking of the lever. Detent assembly (34) is provided for retaining spool (30) at selected rotational positions representing lawn mower transmission settings.
