Abstract: A load securing device includes a lever binder used with chains or a similar fastener. The binder includes a sealed bearing, a shock cover, and ergonomic operational handles. The load securing device includes a first draw bolt and a second draw bolt that extends away from opposing sides of the bearing and are thus linearly arranged with respect to each other. The bearing is sealed to prevent rust or binding of the ratchet device with environmental debris.

Abstract: A lineman's hoist that can be operated by a drill or similar device by its engagement with the head bolt. The head bolt is freely disposed with a head shaft and the head bolt is threadably engaged with a threaded shaft to displace the threaded shaft with respect to the bolt shaft. Thus this can move and displace items or wires that may be connected to the first hoist hook or second hoist hook.

Abstract: A power drive assembly is provided for an elongated turn buckle-type cable tightener having an elongated sleeve with a driven gear wheel on it, and two loop-defining cable and anchors respectively threadedly engaged in its opposite ends. A drive unit is adapted to be coupled to the sleeve and has a motor-driven gear engageable with the driven gear for rotating the sleeve. Two right-angle reaction bars couple the frame of the drive unit to the cable anchors each reaction bar having one end slidably received in openings in the drive unit frame and another and received through the loop of the associated cable anchor.

Abstract: A power drive for an elongated cable tightener having an elongated sleeve and a driven gear wheel supported on the sleeve is provided. The drive includes an outer frame having connected, and laterally spaced, elongated first and second outer side members, each outer side member having first and second ends, the second ends defining aligned outer notches opening longitudinally outward. The drive also includes an inner frame disposed between the first and second outer side members and supported thereby for movement between engaged and open positions, the inner frame having connected and laterally spaced first and second inner side members, each inner side member having first and second ends, the second ends defining aligned inner notches opening laterally outward of the side members, wherein when the inner frame is in the engaged position the inner notches are aligned with the outer notches whereby the sleeve may be disposed in both the inner and outer notches.

Abstract: A device for cocking a crossbow having a bow (12) and a bowstring (16) includes a main housing (21), a movable shaft (22), a device (31) operatively connected to the movable shaft (22) to laterally move the movable shaft (22), and a back element (70) mounted on the movable shaft (22) to engage the bowstring (16), such that when the movable shaft (22) moves, the bowstring (16) is drawn.

Abstract: A pair of laterally spaced, generally parallel opposite side members are provided and defined corresponding first and second ends. The first ends define aligned notches formed therein opening laterally outward of the side members in directions disposed generally normal to the longitudinal extent of the side members and the notched first side member ends may be hook-engaged over the longitudinal central portion of a turnbuckle assembly having an external gear wheel thereon, with the notched first ends of the side members embracingly receiving the gear wheel of the turnbuckle central portion therethrough. Longitudinal mid-portions of the side members journal a second gear wheel therebetween, and the second gear wheel is mesh engageable with the associated turnbuckle gear wheel. In addition, one axial lend of the second gear wheel projects through the corresponding side member and is equipped with an enlarged hexagonal head (or the equivalent) with which an impact wrench may be operatively engaged.

Abstract: In a bearing and support for use either as a bearing, per se, or as a bearinged support for other items and incorporating the bearing of this invention; the bearing includes at least a pair of rotatable members that rotate or counter-rotate about a common axis, a shaft supporting the rotatable members for rotation about its common axis; roller, ball, sleeve, or other forms of bearings disposed between the rotatable members and the shaft to facilitate the rotation of the members therearound; a structural member incorporating a series of keepers upon its upper and lower edges and which retain races or tracks, and being disposed for having one of the rotatable members associated thereon to provide a bearing suspended support for holding other items, or the body of a person.

Abstract: The present invention relates to an ordinary pulley whose pintle is born by a shell provided with a device for suspension from a fixed point and which is adapted to receive a handling or hauling rope, said shell further comprising an auxiliary braking system independent of the pulley, in which said rope is engaged only when the device is to be used as a rescue device for lowering persons, particularly injured or unconscious persons.
