A method and apparatus for restricting rotation of a threaded fastener, the apparatus including a bracket member having a securing segment and an extending segment that are integrally linked wherein the securing segment forms a recess and the extending segment forms at least one restraining surface wherein a bonding material that solidifies and remains flexible upon curing is provided within the recess and, with the threaded fastener received within an aperture, the bracket member is positionable such that one end of the threaded member is receivable within the recess and within the bonding material prior to curing and the restraining surface contacts a surface of a receiving member to restrict motion of the bracket member about the aperture.

Restraint method and apparatus for threaded fasteners

A detachable securement apparatus for a mounting rail, wherein the mounting rail has first and second mounting flanges extending lengthwise along opposite sides of a support section. The apparatus has a body, a securement assembly and a release assembly. Extending from the body, the securement assembly has first and second interface members each including a contact region configured to exert a holding force on the first and second mounting flanges, respectively. The release assembly is configured for removing the holding force on both the first and second mounting flanges to allow vertical removal of the body. The release assembly has an engagement member coupled to the body and to the first and second interface members, and is engagable on a side of the body. A method of attachment and detachment with flanges of a rail mount assembly includes springably coupling first and second sides of a conductive mounting member to the first and second flange, laterally engaging a release actuator coupled to the mounting members, and simultaneously releasing the first and second sides of the mounting member from the flanges.

A reversible ratchet wrench includes a ratchet body having a round head portion with a cylindrical, internally toothed opening therethrough forming a ratchet gear and defining a cavity. A ratchet mechanism, including a drive body, a pawl assembly and a reversing member, is disposed in the cavity, with the reversing member secured to the drive body for confining the pawl assembly therebetween. The head of the ratchet body has annular shoulder surfaces thereon respectively at opposite ends of and coaxial with the cavity, and respectively facing annular shoulder surfaces on the drive body and reversing member, for cooperation therewith to define first and second annular spaces, in which are respectively disposed annular seal members, each having a pair of radially inwardly extending and axially diverging flexible and resilient lips, respectively engageable with the shoulder surfaces defining the associated space for cooperation therewith to seal the cavity and center the ratchet mechanism on the head.

Sealed reversible ratchet wrench

A reversible ratchet wrench includes a main body, a drive gear housed within a gear end of the main body, and a pawl assembly housed within a pawl end of the main body. Further included are a reversing lever, a screw for securing the reversing lever to the pawl assembly, and a coverplate for retaining the drive gear and pawl assembly within their respective gear and pawl ends in the main body. The coverplate is coupled to the screw in a way which permits rotation of the reversing lever relative to the coverplate.

Reversible ratchet wrench

A reversible ratchet wrench has a wrench handle with a circular ratchet head having a cylindrical array of ratchet teeth and receiving coaxially rotatably therein a drive body. A pawl is carried by the drive body for movement between forward and reverse conditions of engagement with the ratchet teeth, being retained in each of these positions by an over-center spring engageable with a pin on a reversing lever disposed coaxially with the drive body and retained thereon by a bushing and a screw for rotation relative to the drive body and the ratchet head for shifting the pawl between its forward and reverse conditions. Indicia on the bushing and the reversing lever cooperate to indicate the condition of the pawl.

A magnetic pickup tool includes an elongated, flexible, tubular, conductive shaft connected to a handle at one end and to an electromagnet at the other end. The handle is an electrically conductive tube housing batteries and a push-button switch for connecting one battery terminal to the housing, the other battery terminal being connected to an insulated conductor which runs through the shaft for connection to one terminal of the electromagnet, which is provided with telescoping inner and outer pole pieces. A first tubular metal coupler electrically connects the handle to the shaft. A second metal tubular coupler has a diametrically slotted end which is received telescopically between the electromagnet pole pieces in contact with each, the electromagnet coil terminals being accommodated in the slot, the other end of the connector telescopically receiving the adjacent end of the shaft in contact therewith. A conductive potting connects the other terminal of the electromagnet to the tubular connector, while insulating potting fills the remainder of the slot and insulates the wire conductor and the one terminal of the electromagnet from the pole pieces and from the tubular connector.

A ratchet mechanism in a reversible ratchet wrench is sealed by novel means. The sealed reversible ratchet wrench includes a ratchet body having a head portion and a handle portion. The head portion has a head cavity formed therein, which cavity receives the ratchet mechanism. The ratchet mechanism communicates exteriorly of the head cavity via at least two journal bearings which respectively receive journal pins associated with the ratchet mechanism. The novel sealing means comprises a pair of annular lip seals, each of which includes an opening that receives one of the journal pins. The annular lip seals bridge the gap between the exteriorly communicating journal bearings and journal pins, thereby facilitating the retention of lubricant and hindering the entry of foreign particles in the head cavity and ratchet mechanism housed therein.

An adjustable dockboard having an improved lip counterbalancing mechanism. The dockboard includes a ramp that is pivoted at its rear edge to a loading dock and is adapted to be moved from a generally horizontal cross-traffic position to an upwardly inclined position. A lip is hinged to the front edge of the ramp and can be pivoted from a pendant downwardly hanging position to a partially extended position short of its fully extended position by a lip lifting mechanism which is actuated as a consequence of the ramp moving downwardly from the inclined position to the cross traffic position. To aid in swinging the lip to the extended position, a counterbalancing spring is connected through a linkage to the lip, and the linkage provides a relative small counterbalancing force when the lip is in the pendant position, and a substantially greater counterbalancing force when the lip is in the extended position. The counterbalancing mechanism aids in pivoting the lip to the extended position, and also acts to cushion the fall of the lip to the pendant position.
