Abstract: A universal joint for power drive tools and the like. The universal assembly includes a means for connection to a tool and a means for engaging the nut or a head of a fastening member, such as a bolt. Articulation of the universal is accomplished by means of a quadrified ball in a square socket. The head of the ball retains its spherical form, and the base of the socket is spherical in shape to accommodate the ball head. The four sides of the quadrified ball do not intersect thereby retaining the spherical configuration of the ball at the corners. A unique ball spring preloads the socket. The resulting combination is ideally suited for power drive tools wherein the forces generated are high, and the rotation is rapid.

Abstract: A universal joint is provided for transmitting torque from one shaft to another, and more specifically for use with shafts where angular misalignment is not excessive. Basically, the universal joint has at least two members connected to two shafts which tend to be angularly misaligned, with each member having at least two extremities extending transversely outwardly beyond the corresponding shaft. The extremities have projections extending toward one another and flexible bridging strips are connected between the projections of the members, the strips lying substantially in a plane which is parallel to the planes in which the members rotate when the shafts are aligned. The flexible strips comprise multiplicities of substantially parallel fibers extending the lengths of the strips and are effective in tension to transmit torque from one of the shafts to the other.

Abstract: A drill string shock absorber has a dual spring system for absorbing vibrations and shock loads during rotary well bore drilling operations. A first spring acts in compression when sufficient weight is set down on the drill bit through the shock absorber to overcome the fluid pressure forces tending to extend the shock absorber, and a second spring acts in compression when the weight applied to the bit through the shock absorber does not overcome the fluid pressure forces. A splined connection transmits torque to the shock absorber during drilling operations, and seals are provided between the telescopic shock absorber components for confining therein a body of lubricant, the pressure of which is equalized with the pressure of drilling fluid flowing through the shock absorber.

Abstract: A device for coupling power from a high speed rotating flexible shaft to a spindle of a portable worktool. The flexible shaft is contained within a casing. The casing is crimped within a ferrule which is threaded into a handpiece which an operator holds in one hand to guide the worktool. Upon movement of the worktool on the workpiece by the operator, the casing becomes twisted to encourage loosening of the threaded connection between the ferrule and handpiece, thus endangering the operator. In lieu of the prior art threaded connection between the ferrule and handpiece, a retaining member engages both to prevent their dangerous separation by virtue of the handpiece and retaining member being free to slowly rotate about the ferrule in a direction to automatically relieve twisting stresses introduced into the casing caused by movement of the worktool by said handpiece on or about a workpiece.

Abstract: A winch transmission and control which through selective energization of separate parts of the transmission enables the winch to automatically change to a different output speed, produce a fully braked condition, or a freewheeling condition. Reversing of the direction of the drum occurs through reversing the direction of the power input motor to the transmission. A unique, single lever hand control is operatively associated with means for energizing the clutch mechanisms which control the various parts of the transmission as well as control the reversibility and stroke of a pump which drives the input motor. The hand control assures a proper correlation between braking and powering of the drum. Another unique feature is a combination cable guide and external structural tie bar for a hollow drum of a towing winch used on a towing vehicle for strengthening the winch drum case. Another unique feature is a technique for installing large, slow-speed ball bearings in a bearing race.

Abstract: Remote control flexible shaft having a balanced torsion deflection in either direction of rotation when subjected to torsional loads. Balanced torsional deflection provides the same "feel" of the control element, whether a wheel, valve, knob, or the like, and the same "lag" period before response of the controlled element, regardless of direction of rotation of the control element. The shaft employs interconnected equal lengths of conventional flexible shafting of identical construction except for the opposite lay of the wires comprising each respective layer of each length. Specific torsional deflection characteristics may be obtained by varying lengths and/or construction of the two flexible shaft lengths, or more than two lengths of shafting may be employed.
