  • Patent number: 4188553
    Abstract: An electrical insulating pocket receptacle for securing a sensing element within electrical windings of a motor includes a sheet-like flexible material having a body support portion supporting a pocket within which the element is located and having four tabs projecting from the body support portion. The tabs on the opposite side of the pocket are located within the winding and hold the pocket in place within the winding with an exposed open end for insertion and removal of the element. A wire holding tab is secured to one of the support tabs and is folded upon itself and secured against the coil end turns by the end tie cords. A third locking tab is pulled down over the spade of the sensing element to securely hold the sensing element in place. A fourth tab may be used to fold over the pocket to additionally insulate the sensing element from the windings of the motor in which the insulating pocket receptacle is inserted.

  • Patent number: 4187644
    Abstract: A multiple spindle honing machine of the disclosure includes automatically controlled feed cylinders for initially expanding honing tools driven by the spindles and also includes a constant rate feed mechanism that continues to expand the tools after the initial expansion actuated by the feed cylinders. Each spindle includes a connector that extends between one of the feed cylinders and its associated honing tool. Mechanical locks respectively lock first threaded members of the connectors after the initial tool expansion. Second threaded members of the connectors are unthreaded from the first members thereof by an actuating member, preferably embodied by the gear rack, of the constant rate feed mechanism so as to continue the tool expansion and completion of honing operation. Electrical and hydraulic circuits control operation of the pressure feed cylinders, the constant rate feed mechanism, and the mechanical locks.

  • Patent number: 4179877
    Abstract: A mounting structure incorporated into the dashboard of an automotive vehicle or the like for removably supporting a portable, self-contained, battery operated alarm clock to enable the clock to be easily mounted in the dashboard and just as easily removed therefrom to enable the clock to be used in the vehicle in a customary manner and removed therefrom and carried to any desired location for use as a portable alarm clock having general utility. The clock is especially useful by travelers since it can be taken out of the automobile and into the motel or hotel room so that it can be used as an alarm clock. The mounting structure and clock are uniquely associated so that the clock may be easily inserted but yet securely retained in the vehicle dashboard even when traversing rough or uneven roadways and the like with a manually manipulated structure enabling easy removal of the clock from its secure position in the dashboard.

  • Patent number: 4178790
    Abstract: A roll-through cold forming apparatus adapted to form simultaneously a plurality of either external or internal straight spline or gear type teeth on a cylindrical workpiece carried on a movable ram. In one embodiment the apparatus includes a plurality of radially disposed pivotally mounted teeth forming blades which are disposed around the axis of movement of a linearly movable ram, whereby when the ram moves in one direction past the teeth forming blades, the blades are engaged by an interference contact with the workpiece carried on the ram, and the teeth forming blades are moved over the external surface of the workpiece in a rolling contact action so as to displace the material of the workpiece between each tooth forming edge of each of the blades. The material on the external surface of the workpiece is formed around the radius of each of the tooth forming edges of each of the forming blades on a line with the configuration of each tooth forming edge.

  • Patent number: 4174773
    Abstract: A tip-up and mounting apparatus in a sortation conveyor includes a support angle, upstanding mounting angles, mounting brackets, and a tray engaging roller mounted on crank arms pivoted to the mounting brackets. The mounting angles are disposed with their apices facing outwardly of the conveyor, thus providing a mounting surface at 45.degree. to the conveyor's machine direction for the mounting bracket. The crank arms are pivoted to the mounting bracket, and this configuration provides an in and out component of motion to the rollers during their movement to and away from sortation tray engagement, thereby maintaining a short roller dwell time in tray interfering position. Adjustable construction of the components, together with a self-aligning actuating cylinder mounted within the mounting bracket reduces bulk and provides a highly tunable and smoothly operating tip-up apparatus.

  • Patent number: 4174777
    Abstract: A zero pressure accumulating conveyor is provided from a standard belt driven live roller section and "bolt-on" accumulating elements. The accumulator includes a plurality of accumulation zones, each zone having an article sensing apparatus and frictional braking apparatus for braking at least one roller, and preferably less than all rollers, in the zone. Each sensing apparatus includes a first valve, actuated in response to an article in the respective zone for pressurizing the brake apparatus. All zones, except the downstream-most zone, have second valves. The second valves, in a respective zone, are opened in response to actuation of the first valve, in the immediate downstream zone, for passing the pressurized air from the first valve in the respective zone to the brake apparatus in the respective zone only when an article is sensed in the immediate downstream zone, and a subsequent article is sensed in the respective zone.

  • Patent number: 4173817
    Abstract: A machining center type machine tool which is a four-axis, horizontal spindle machining center with a carousel-type automatic tool changer and which is adapted to be controlled by a computer numerical control system. The machining center can perform a variety of machining operations, such as milling, contouring, drilling, tapping and boring, in both roughing and finishing applications. A rotary work table is operatively carried on two movable, perpendicularly disposed slide members to provide movement of the work table along both "X" and "Z" axes. A horizontal tool spindle slide assembly is slidably mounted on a "Y" axis on a twin column assembly. A rotary, carousel-type combination tool storage and tool changer, holding twenty-four tools, is rotatably mounted on a horizontal axis that is aligned and parallel with the axis of the horizontal tool spindle. The rotary carousel functions to automatically load and unload tools directly into the tool spindle at a tool exchange location.
