  • Patent number: 11111916
    Abstract: A reciprocating pump assembly that includes a power end, first and second stay rods coupled to the power end, and a fluid end that includes a mounting flange coupled to the first and second stay rods and a packing nut assembly. The packing nut assembly includes a packing nut threadably engaged with the mounting flange and comprising a gear pattern, and a retention assembly that includes a collar, an alignment arm, a pawl, and a biasing assembly. The collar extends around the first stay rod. The alignment arm is coupled to the collar and shaped to contact the second stay rod. The pawl is pivotally coupled to the alignment arm or the collar and positioned to engage the gear pattern to allow the packing nut thread into the mounting flange and prevent the packing nut from unthreading. The biasing assembly biases the pawl into engagement with the gear pattern.

  • Patent number: 10527465
    Abstract: A system for counting wheel revolutions made by a wheel of a vehicle, the system including an electronic counter, a transmitter, a housing, and a connector. The electronic counter counts a number of wheel revolutions made by the wheel. The transmitter transmits data from the electronic counter to a remote database. The housing houses the electronic counter. The connector removably attaches the housing to a nut anti-loosening device installed on the wheel.

  • Patent number: 10267345
    Abstract: A splice component for tubular members includes a splice plate having a linear arrangement of spaced apart openings extending along a length of the splice plate, and a plurality of nuts aligned with the splice plate openings and loosely retained in place by a nut capture arrangement. The nut capture arrangement is formed at least in part by an elongated U-shaped cover plate having spaced apart side support legs on opposite sides of the linear arrangement openings, and a bridging part extending between the spaced apart side support legs and over the linear arrangement of openings. At least one elongated retaining plate extends between and is fixed to the spaced apart side support legs.

  • Patent number: 5415509
    Abstract: An improved lock plate and retaining ring mounting arrangement for securing a gear on a vehicle rotating shaft by a threaded hex-head fastener. The plate has a generally rectangular central aperture with transversely opposed internal side edges and longitudinally opposed arcuate end edges. The plate has a pair of arcuate opposed concentric slots sized to adjustably receive an associated web bolt for threaded reception in a web bore thereby locking the shaft fastener in its tightened position. A one-piece retaining ring, concentrically positioned so as to overly the plate, comprises opposed semicircular bands interconnecting a pair of diametrically opposed discs provided with a bolt hole adapted aligned with both an associated plate slot and a web bore. Each disc is formed with a plurality of radially disposed tabs whereby at least one of the tabs is in substantial registration with a side face of an associated web bolt head.

  • Patent number: 4885834
    Abstract: Each dual wheel assembly on a tractor or trailer system includes outer and inner wheels mounted on a plurality of studs projecting from a hub. The inner wheel is held in place on the studs by a number of flanged cap nuts and the outer wheel is held in place by a number of wheel nuts. When unthreading the wheel nuts to remove the outer wheel, some of the cap nuts invariably remain engaged with the wheel nuts whereas the cap nuts should all remain engaged with the threaded studs during this step. The device disclosed herein is in the form of a ring having a number of hexagonal holes therein corresponding to the number of wheel nuts so that the ring can be placed over those wheel nuts remaining engaged with their cap nuts to prevent rotation of the wheel nuts when each cap nut is individually spun out through the back side of the removed outer wheel.

  • Patent number: 4781502
    Abstract: An anti-rotation locking device for threaded fasteners which secure rotating parts subject to vibration, shock and the like. The device comprises a strap member and one or more retainer members. The strap member is positioned under the fasteners and the retainer members each have a toothed opening which is installed over the matching wrenching surface of the fastener. Each retainer member also has an arcuate slot which is positioned above an arcuate tang on the strap member. The tang is lifted, passed through the slot, bent about the bottom of the slot and folded back over the top surface of the retainer member to thereby restrain the loosening of the fastener.

  • Patent number: 4684281
    Abstract: A shifter boss mounting assembly includes a member threaded at each end and extending diametrically at least partway through a bicycle frame downtube formed with openings therein, a pair of shifter boss bases with inward surfaces conforming to the downtube outer surface, and a pair of shifter studs that extend through the base and a respective opening in the downtube and thread onto the corresponding threaded ends of the member. A projection on each base cooperates with an opening or indentation in the downtube to restrain the base from rotational movement. A lock washer or a plate keyed to cooperate with the base and the stud restrain the stud against unthreading when the shift levers are pivoted. Once mounted, the boss assembly is standardized in its external configuration to bosses adapted to receive standard commercial shift lever assemblies.

  • Patent number: 4657457
    Abstract: A locking device for securing at least two screw-action connectors comprises a locking clip or element made from a good quality spring steel wire having a round or square section. The locking clip or element has a diagonal interconnecting part which extends tangentially between a pair of locking elements one at each end of the part. The locking elements (for example, coils) are wrapped round or placed over a portion of a wheel nut. The interference/friction fit between the wheel nut and the clip or element prevents axial movement of the clip relative to the nut. The part serves as restraining means positively linking tangentially adjacent wheel nuts and thereby prevents relative rotation thereof.
