  • Patent number: 5362171
    Abstract: A shackle toggle joint for driving a warp knitting machine comprising a housing of synthetic material having a metal ring (13) for holding a roller bearing (16) imbedded therein. The roller bearing (16) carries a joint bolt (11). The housing (12) further comprises a securing means in the form of a threaded bore (19) for holding a connecting element. There is thus obtained a higher working life for the roller bearing and a lower level of working noise.

  • Patent number: 5209594
    Abstract: An arrangement for locking a shaft or an axle to a machine member. The shaft has a cylindrical part which is intended to carry a bearing. The arrangement includes two expander sleeves which have a control internal shape and each of which is intended to be mounted on a respective end of the shaft of similar conical shape. The expander sleeves function as annular wedges with the apex of the wedge facing towards the cylindrical part of the shaft or axle and when tightening a nut are caused to expand against the machine member and lock the shaft.

    Abstract: A sleeve and bushing assembly for mounting a shock absorber to a motor vehicle and reducing road vibration experienced by the motor vehicle, as well as a method of manufacturing the assembly. The sleeve and bushing assembly includes an elastomeric bushing having first and second ends and an axial bore extending therebetween. A tubular cylindrical sleeve extends through the axial bore and terminates in a first shoulder at one end thereof and in a second shoulder and neck portion at the other end thereof. A first retaining washer is mounted on the sleeve adjacent the first shoulder and the first end of the bushing. A second retaining washer is mounted on the sleeve adjacent the second shoulder and its neck portion of the second end of the bushing. A spacer ring is mounted on the sleeve's neck portion adjacent to the second retaining washer.

  • Patent number: 5088881
    Abstract: A tractor-loader-backhoe is disclosed wherein the loader mechanism is mounted on the frame of the prime mover by a tapered pivot pin or sleeve having a fastener extending entirely through the axis of the pivot pin or sleeve to effect a clamping load operable to seat the tapered pivot pin or sleeve in the conical hub affixed to the frame of the prime mover to assure a firm fastening of the loader mechanism on the prime mover. The backhoe mechanism is provided with a transport lock remotely actuatable from the operator's cab mounted on the prime mover and incorporating a locking pin having a concentric spring mounted thereon to urge the pin out of engagement with the frame whenever the transport lock is disengaged to permit operation of the backhoe mechanism. The boom and dipper members of the backhoe mechanism are constructed from a pair of opposing C-shaped channels having inwardly directed legs centrally located within the boom and dipper members.

  • Patent number: 5082387
    Abstract: A pivot joint for a rotary lever has a spacer extending axially from a foundation such as an engine motor component. The spacer includes a cylindrical ferrule. A rotary lever and a belleville spring, both having a bore of a size to fit over the outside of the ferrule in a sliding fit, are slid over the ferrule. The belleville spring has an uncompressed cone height to thickness ratio of 1.4 to 1.8 and is compressed by at least 50% of the uncompressed cone height. The joint also includes a means for fastening the spacer to the foundation and a means for securing the lever and belleville spring onto the ferrule. The securing means bears against the free end of the ferrule to compress the spring to provide a substantially uniform operating torque from one assembly to another.

  • Patent number: 5044812
    Abstract: A sealed and lubricated pivot pin assembly and method for joining linkage components in earth-moving machinery. The pivot pin assembly includes a pivot pin subassembly, a pair of spacer rings, a pair of track chain type annular seals, an end cap subassembly, and a releasable fastener. The spacer rings simplify joint assembly by setting up and controlling the proper squeeze on the annular seals, preventing crushing of the annular seals during torquing of the releasable fastener, and controlling the set-up length of the assembled joint so that no shimming is required. Each of the pivot pin and end cap subassemblies include an end sleeve which extends beyond the joint clevis or brackets a sufficient distance to allow the pivot pin assembly to float axially and, thereby, compensate for minor deflections in the joint members. The pivot pin assembly is symmetrical in that the pivot pin and end cap subassemblies have common dimensions which permit the pivot pin assembly to be installed from either side of a joint.

  • Patent number: 4995576
    Abstract: The mailbox support-mounting disclosed has a pivoting arm. If the mounting receives a blow, e.g. from a snow-plow blade or from a vandal, the arm swings aside. After swinging aside, the arm resets itself to a central equilibrium position. The restoring force to reset the arm is provided by gravity, in that the pivot axis is set at an angle, and slopes forwards towards the road. The pivot bearing is sturdy and well-located, yet the bearing is inexpensive and not prone to seizure.
