  • Patent number: 4708698
    Abstract: A driving sprocket to drive conveyor chain on a finger jointing machine having a base plate with central aperture therein. Drive hubs are mounted on opposed faces of the base plate and are adapted to be rotated by conventional power transmission equipment. The drive hubs project into the central aperture and clutch plates are interposed in operative series relation between the drive hub and the related face of the base plate. The drive hubs directly and solidly drive the clutch plates. The clutch plates frictionally drive the base plate. Caliper clutch assemblies control the level of frictional engagement between the respective clutch plates and the related face of the base plate.

  • Patent number: 4636220
    Abstract: An arrangement for adjusting the heel height of a prosthetic foot includes a cavity at the rear aspect of the prosthetic foot adapted to receive a separate locking block therein. Both the locking block and the cavity, as seen inside elevational view, are arcuate in configuration. Secured to the lower aspect of the block are a pair of arcuate rails spaced transversely from each other. Secured to the upper surface of the cavity and in complementary relation to the arcuate rails are a pair of transversely spaced grooves or tracks to receive the respective rails. The locking block may be moved longitudinally and arcuately of the prosthetic foot to thereby adjust the heel height of the foot when it is secured to a prosthetic device. A locking bolt is used to accomplish the attachment of the foot to the device and hold the block in fixed position to maintain the desired heel height.

  • Patent number: 4582461
    Abstract: The invention is the precise mounting of a cutting tool on a rotating spindle to prevent eccentric runout between the spindle and tool and comprises mating non-locking taper surfaces at the inner end of the spindle tool combination and diverging angular taper surfaces at the outer end of the spindle and tool combination. A variable diameter wedge engages the diverging taper surfaces for precise and repeatable accurate mounting of the tool to the spindle.

  • Patent number: 4570608
    Abstract: An inertial archery bow stabilizer and vibration dampner is disclosed. A stud is rigidly embedded in the archery bow and has an energy disipating rod fixed to and projecting forwardly of the stud. The rod is received within an encapsulating sealed cylinder having an internal chamber filled with a viscous fluid in which the rod is disposed. At its outer end and externally thereof, the cylinder is provided with another stud to which the archer may afix a selected stabilizing weight. The stabilizer is effective to limit bow movement during arrow cast and rapidly dampen and attenuate energy released as characterized by dampened bow vibration.

  • Patent number: 4525948
    Abstract: A fishing lure has an internal longitudinal cavity that normally received the stems and eyelet segment of a composite multi-hook. The bowed hooks project externally of the lure body. An abutment is placed at the external opening of the cavity, the abutment being embraced by the stems to provide continuous frictional engagement between the stems and the abutment during relative longitudinal movement between the multi-hook and lure body. The resistance to hook movement inhibits the attacking fish from throwing the hook until the hook eyelet engages the abutment abruptly halting the relative movement and ensuring good hook penetration.

  • Patent number: 4524763
    Abstract: A therapeutic apparatus for use in the lumbar spine traction treatments is disclosed. The apparatus includes a conventional body harness adapted to connect to the patient's body just below the rib cage. Features of the device include first and second support frames carrying a body support board in different angular relations with the horizontal depending upon which is placed on the floor. The apparatus or device allows the patient's legs and feet to project beyond the lower edge of the support board whereby the patient may move his thigh leg segments to effect movement of the lumbar spine to the best position for traction application. Movable feet support means allow for the variable positioning of the patient's feet both horizontally and vertically accomodating the ideal degree of lumbar spine flexion in each individual patient case.

  • Patent number: 4525097
    Abstract: A force multiplying and locking arrangement is disclosed to lock, for example, a cutting tool to a spindle. It comprises main body arranged to be threadably mounted on a spindle, said main body having a pressure ring at its forward aspect mounted to accommodate movement longitudinally of the arrangement and to inhibit movement rotationally of the arrangement. A cavity is defined by said pressure ring and said main body and includes an inclined plane. The cavity has a plurality of spherical balls disposed therein. Said main body is peripherally threaded to accommodate the threadable mounting of a compression ring having, at its forward aspect, a conical inclined plane overlying the cavity and the first mentioned inclined plane. Rotation of the compression ring forces the spherical balls into the cavity engaging the inclined planes and the pressure ring and greatly multiplying the force for locking the device. Reverse rotation of the compression ring releases the locking force.

  • Patent number: 4489907
    Abstract: A system for altering the lift/drag characteristics of powered general aviation aircraft whereby flight path control may be exercised. The control device operates in conjunction with such lift/drag altering devices, spoilers, dive brakes and the like, and is physically unitary with the pilot's operation of the throttle control. Utilizing a single control, the pilot may selectively maintain the craft without lift/drag modification, with automatic lift/drag modification at lower power settings such as under landing approach conditions and lift/drag modifications at higher power settings and without modifying the power setting. A vacuum operated valve having simple selectable operational modes provides flight path control desired. Vacuum distribution means, i.e., vacuum lines are provided from a vacuum source, to the vacuum valve and to the spoilers and dive brakes for bellows actuation of the lift/drag altering devices.

  • Patent number: 4473176
    Abstract: A security mounting device for a chain saw is disclosed which consists of a base plate carrying a downwardly directed channel spaced above and at one end of the base plate. The channel is adapted to receive and embrace the operator's handle of a chain saw. A pair of transversely spaced plates are carried at the other end of the base plate and project upwardly therefrom and are adapted to receive therebetween the chain bar of the saw. Holes are provided in the upper ends of the spaced plates which receive a demountable pin, said pin, when in place, being adapted to confine the chain bar within the transversely spaced plates. Resilient means such as rubber-like pads may be carried by the base plate and the channel to flexibly engage the saw motor housing and operator handle, respectively. The pin may be provided with a hole to receive a conventional pad lock to prevent removal of the saw from the device.

  • Patent number: 4077515
    Abstract: A medical slide enclosure case comprises non-separable congruently mirrored segments of molded plastic. The segments are joined by an integrally molded thin hinge line. Case closure is accomplished by molded hooks on the segments in snap closure alignment with molded wall edges and opposed to the hinge line. Case segments include internal walls defining a slide receiving cavity. The cavity includes spacer ledges to maintain the received slide surfaces in spaced relation to the inner case surfaces. The case includes a defined finger cavity adjacent to slide cavity facilitating easy insert and removal of the medical slide from the case.
