    Abstract: A fastener driving device including a housing providing a fastener drive track and an elongated hollow handle portion extending transversely with respect thereto within which an elongated drive spring is mounted in peripherally confined relation so as to enable the housing to have a low profile and to permit more efficient utilization of its spring energy to effect rapid fastener driving. The spring is compressed by movement of a spring actuated member thereagainst in response to the movement of an actuating lever and pawl through an actuating stroke, as by a manual gripping action between the actuating lever and the handle portion of the housing. The actuating lever and pawl having a togglelike action which increases the mechanical force transmission as the spring is progressively compressed. The spring actuated member is released at the end of the actuating stroke of the actuating lever so as to be moved through a spring actuated stroke by the compressed drive spring, which movement is transmitted to the fastener driving element of the device by means of a bellcrank in such a way that the drive stroke of the fastener driving element is through a greater distance and at a greater speed than the spring actuated stroke of the spring actuated member. Resilient bumper means disposed at an acute angle to the horizontal is provided for engaging the bellcrank and cushioning the end of the spring actuated stroke of the parts. A fastener magazine is provided to feed a fastener from a contained supply to the drive track to be driven by the fastener driving element during its drive stroke, the latter being normally biased into a position corresponding to the end of its drive stroke and being moved through a retraction stroke by the operation of the bellcrank when the actuating lever is moved through its actuating stroke. The fastener magazine includes a movable member which is slidable rearwardly to permit fasteners to be inserted in the magazine assembly from the bottom. The movable member is positively secured to a fixed member in operative position by means of a releasable locking pin mounted in slots in the movable member and resiliently biased into engagement with a notch in the fixed member. The parts constituting the fastener driving mechanism and its housing are constructed in a manner such that relatively few manipulative steps are required to assembly an operating embodiment.

    Abstract: A DEVICE FOR IMPROVING THE ACURACY OF THE TESTING AND CALIBRATING OF GAS METERS BY MEANS OF THE FLOW RATE, RATHER THAN A STATIC MEASUREMENT, TO REDUCE ERRORS DUE TO TEMPERATURE VARIATIONS IN THE GAS. THIS IS ACCOMPLISHED BY CONNECTING THE METER TO A PRESSURE REGULATOR THROUGH AN ORIFICE AND CONNECTING THE UPPER CHAMBER OF THE REGULATOR TO A POINT BETWEEN THE ORIFICE AND METER TO CONTROL THE REGULATOR BY SENSING THE PRESSURE BETWEEN THE ORIFICE AND METER.

    Abstract: A unitary piece for mounting on the cover of an electrical underfloor access unit or the cover of a junction box unit. While the adapter permits floor carpet to be installed directly over the unit and thereby preserve carpet continuity, it nevertheless provides ready access to the cover for maintenance and/or conductor installation purposes.

    CPC classification number: B27F7/34

    Abstract: The invention relates to a fluid-pressure-operated device for driving fasteners through material whereby a shuttle piston pushes a shuttle towards the material to compress the material against a fixed clincher and a driver piston pushes a driver blade towards the material to drive a fastener into the material after the shuttle has compressed it. In the embodiment described in detail the pistons are of the differential type and move linearly and with a constant angularity with respect to the clincher.

    Abstract: A spherical bearing is described wherein a ball member is retained and supported by a hardened spherical seat, the latter being defined by an insert bushing that is integrated into a socket structure. The bushing with a truncated bearing ball nested by the inner bushing surface is fusion welded around the outer periphery of the bushing to a housing to form an integral load-carrying part thereof. The fusion weld also extends a substantial axial distance or depth and is preferably made with an energized beam such as a beam of electrons. In the formation of a spherical bearing for a rod end, a pair of annular bushings is formed with each bushing welded to the rod end housing to form an integral load-carrying part of the rod end.

    CPC classification number: B23Q35/126 B23Q35/14 Y10T82/2506

    Abstract: A tracer control system is provided for use in conjunction with turning machine tools, such as horizontal lathes or vertical turret lathes. The system of the invention provides an automatic control for the cutting tool of the machine along any desired two-dimensional path, as determined by the engagement of a sensing head stylus with the edge of a flat template. The control system to be described includes unique control circuitry which permits the turning speed of the machine to increase as the cutting tool is moved towards the center of rotation, and at the same time controls the rate of movement of the cutting tool tangent to the surface of the workpiece so that constant cutting speed may be achieved with a constant chip thickness as the cutting tool traverses the workpiece.
