Patent number: 4569614Abstract: A coupling for fastening two members whose opposed faces keep an equal gap and are free to relatively displace to the left or right, wherein a wedge inclining with an angle narrower than the friction angle to osculate each of the opposing face of the members, is capable of wedging the opposing faces by relative displacement of the members toward the rising side of the wedge. The coupling is arranged on the left and right respectively in the direction of relative displacement of the members, so that two members can be coupled plainly, rigidly and free from lowering of the axis strength, permitting an easy phase adjustment or dividing or the like.Type: GrantFiled: June 30, 1982Date of Patent: February 11, 1986Inventor: Yukio Yamauchi

Patent number: 4566400Abstract: An improved bell is disclosed which features a clapper continuously adjustable for hardness of strike. The clapper comprises a hard inner member and a resilient outer member. The periphery of the clapper is circular but the hard inner member is not circular about the same center as the periphery so that the amount of resilient material between the solid inner core member and the periphery varies circumferentially around the clapper. At the time of manufacture of the bell it is tested to locate the point on the bell body at which "wow and flutter" in the tone emitted by the bell is minimized. A single insulated pin serves to orient the handle of the bell, the bell body and the plane of swing of the clapper. The attachment of the handle, the bell body and the clapper is such as to minimize extraneous noise. An elastomer clapper shaft is employed, and its effective flexing length may be varied.Type: GrantFiled: July 29, 1983Date of Patent: January 28, 1986Assignee: Schulmerich Carillons, Inc.Inventors: Charles E.

Patent number: 4129206Abstract: A conveyor carries a plurality of pegs for supporting and rotating cylindrical containers having one open end and one closed end, each peg having a central pin mounted in the conveyor and a steel sleeve rotatably carried on the pin, the steel sleeve extending for a maximum distance within the carried container for uniform support and stability of the container on the peg, and the steel material acting against the wall of the container to provide proper friction for container rotation with stability. The inner end of the sleeve has an enlarged hub for rolling on an associated bar for rotating the sleeve on the pin, and a spacer tube holds the open end of the carried container at a distance from the hub. In a modified form, the pin extends only a small fraction of the length of the sleeve and the sleeve is held on the outer end portion of the pin by friction, the sleeve being scored outwardly from the end of the pin to bend or break under stress without damaging the pin.Type: GrantFiled: March 24, 1977Date of Patent: December 12, 1978Assignee: Coors Container CompanyInventor: Roblee L. Talbott

Patent number: 4121675Abstract: Apparatus is disclosed that includes a housing through which extends a shaft, such as a drill string. A body of wire mesh is carried by the housing and located between the housing and the drill string. The wire mesh is compressed to cause it to expand laterally into engagement with the housing and drill string to hold the housing from movement relative to the drill string, to attach, for example, a stabilizer to the drill string, or to support at least a portion of the weight of the drill string.Type: GrantFiled: October 4, 1976Date of Patent: October 24, 1978Assignee: Maurer Engineering, Inc.Inventor: Jeddy D. Nixon

Patent number: 4097164Abstract: An elongate terminal body has a longitudinal bore which receives a wire rope or strand. A deformable member surrounds the rope or strand in an enlarged part of the bore adjacent the end at which the rope or strand enters. The terminal body is compressed to grip the rope or strand so that the deformable member is gripped between the terminal body and the rope or strand. The deformable member dissipates transverse and longitudinal vibrations transmitted along the rope or strand towards the terminal body.Type: GrantFiled: July 12, 1976Date of Patent: June 27, 1978Assignee: Bridon LimitedInventor: Robert Edward Campbell

Patent number: 4097756Abstract: A rotation indication system having an improved sensing device for determining the velocity of a rotating body is disclosed. The improved sensing device is tubular in configuration and includes a source of magnetic flux and two pole pieces that define a split magnetic field. The sensing device is mounted in close proximity to a rotor which is connected to the rotating body. The rotor has apertures which interrupt the split magnetic field producing an output signal with a frequency proportional to the velocity of the rotating body. The sensing device is oriented relative to the rotor apertures so that each pole piece is alternatively in register with an aperture to produce the desired output signal. Since the sensing device is tubular in shape, it can be rotated about its axis to obtain the desired orientation with the rotor apertures, thus permitting the use of the sensing device with a wide range of rotor diameters having various aperture spacings.Type: GrantFiled: January 28, 1976Date of Patent: June 27, 1978Assignee: Eaton CorporationInventor: Thomas A. Gee

Patent number: 4095855Abstract: A gas lubricated spindle bearing assembly comprising a stator assembly and a rotor assembly with a spindle engaged to the rotor and a twin parallel flexure engaged to one of said assemblies to establish and maintain an air spacing between the adjacent interfacing surfaces of the said stator and rotor assemblies.Type: GrantFiled: September 20, 1976Date of Patent: June 20, 1978Assignee: Fox International, Inc.Inventor: Wayne L. Fox

Patent number: 4093052Abstract: A fluid actuated coupling assembly for releasably coupling together of at least two elements and preferably transmitting torque between them. An inner metal sleeve and an outer metal sleeve are secured together to define a very thin gap between them. Means are provided to pressurize that gap to cause radial expansion of the gap and the sleeves.Type: GrantFiled: February 23, 1976Date of Patent: June 6, 1978Assignee: Forenade FabriksverkenInventor: Curt Gunnar Falk

Patent number: 4079950Abstract: A self-adjusting wear resistant seal assembly is provided for a cable rod slidably positioned within a cable conduit. A continuous polyethylene collar is radially compressed in close clearance around the rod by an elastomeric seal which embraces the end portion of the conduit and the collar and holds a flange on the collar against the end portion of the conduit. An integral lip on the seal engages the rod to provide a redundant seal. Corresponding serrations on the conduit and seal cooperate to secure the seal to the rod. A tapered lip may also be provided on the collar for engagement with the rod.Type: GrantFiled: April 18, 1977Date of Patent: March 21, 1978Assignee: Incom International Inc.Inventor: William D. Langford

Patent number: 4067658Abstract: Disclosed is an apparatus for holding knobs for turning a channel selector of a television receiver or for similar purposes. A flat plate having a first group of projections adapted to bear against a notched flat portion of a rotatable shaft (tuner shaft) having a semi-circular section, and a second group of projections arrayed to bear against a portion of knob into which the shaft is inserted is employed to obtain a reliable coupling of the shaft and the knob.Type: GrantFiled: October 17, 1975Date of Patent: January 10, 1978Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshinobu Ueno, Tadayoshi Shibata

Patent number: 4050265Abstract: A force-displacement controller knob for use in isometric control devices provided. A controller knob component is mounted on existing control shafts and the knob itself contains a pair of compressible, resilient washers separated by and contacting a rigid washer in a chamber in the knob so that force appied in any direction on the knob will be transferred to the control shaft in a resistance ratio determined by the compressibility of the resilient washers.Type: GrantFiled: August 3, 1976Date of Patent: September 27, 1977Assignee: The United States of America as represented by the Secretary of the NavyInventors: Thomas G. Drennen, Allen Neander
