  • Patent number: 4569614
    Abstract: 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.

  • Patent number: 4566400
    Abstract: 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.

  • Patent number: 4564088
    Abstract: A braking device for arresting an axial relative movement between a bearing, and a shaft slidably engaging the bearing and extending through a cylinder which is axially immovable to the bearing. The device comprises: an annular piston slidably received in the cylinder and slidably engaging the shaft; a brake shoe engaging the shaft axially immovably relative to the cylinder and radially contractible to apply a brake to the shaft; a resilient radial clamp member engaging the outer surface of the brake shoe, axially compressible by axial movement of the annular piston and thereby reduced in inside diameter to force the brake shoe against the surface of the shaft; and a piston driving device for moving the shaft along its axis through a controlled selective supply of a pressurized fluid to the cylinder. The piston driving device may comprise a coil spring to bias the piston to cause an axial compression of the radial clamp member, and a device for effecting the controlled supply of the fluid.

  • Patent number: 4553649
    Abstract: A drum brake assembly includes a pair of brake shoes which are slidably mounted on a fixed support. An elastic retention member is mounted on each of the shoes before they are assembled onto the fixed support. Each of the retention members includes a locking portion which engages the web of the brake shoes, and a pair of arm portions which extend from the locking portions and which engage the web of the brake shoe in such a way as to releasably maintain the locking portion engaged with the web of the brake shoe. When the brake shoes are assembled on the torque member, a portion of the torque member is provided with a sloped edge that engages the locking portion to release the latter as the brake shoes are assembled onto the fixed support, so that the retaining member then exerts a biasing force between the torque member and the brake shoes.

  • Patent number: 4165194
    Abstract: A frictional coupling for a male member inserted in the bore of a female member, to couple together the two members when at a pre-determined axial position. The opposed surfaces of the male and female members define a clearance the radial dimension of which varies as the members are moved axially relative to one another. A frictional coupling element is provided in said clearance, which element comprises a strip of resilient material preformed into a helical coil of polygonal cross-section, such that the outer corners of the coil contact the bore of the female member and the inner flats contact the male member.As the clearance is reduced by relative axial movement of the members, the element is deformed to restrain further movement therebetween.

  • Patent number: 4147445
    Abstract: A coupling arrangement between a shaft and a knob adapted for rotating the shaft, the knob being provided with a recess having a cross-sectional area which is substantially greater than the cross-sectional area of the shaft, and having a sleeve arranged to encircle the shaft with its inner surface and with its outer surface intended to be encircled by the recess in the knob. The outer surface of the sleeve has a cross-sectional area which is somewhat larger than the cross-sectional area of the recess of the knob. The knob is pressed over the sleeve and as a result of its elasticity imparts to the sleeve a compressing force which acts on the shaft and thereby presses the sleeve and the knob into firm, co-action with the shaft.

  • Patent number: 4129206
    Abstract: 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.

    Abstract: 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.

  • Patent number: 4097164
    Abstract: 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.

  • Patent number: 4097756
    Abstract: 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.
