Turnbuckle linkages are disclosed herein. A turnbuckle linkage includes a hollow rod including an inner portion, a first outer portion, and a second outer portion between the first outer portion and the inner portion, the inner portion including a first thickness, the second outer portion including a second thickness less than the first thickness, and the first outer portion including a conical thickness that varies from the second thickness to a third thickness less than the second thickness, the first outer portion and the second outer portion including first threads, a threadless rod to be partially positioned in the hollow rod, and a conical nut including second threads to engage the first threads, the conical nut to couple the hollow rod and the threadless rod.

A locking device for securing a wear element in a support in an earth moving machine includes a central shaft with a first right hand threaded segment and a second left hand threaded segment. Locking elements are screwed onto the threaded segments. Both threaded segments are attached to one another and are suitable for transmitting rotational movement between both threaded segments. A coupling of the threaded segments can comprise a disc with two faces, each of them opposite one end of the threaded segments. Between each of the faces and the end of the threaded segment there is a tongue and groove extending to a first diameter and a second diameter, respectively, such that the disc and the threaded segments are suitable for moving with respect to one another.

A mounting assembly mounts a fluid end unit to a power end unit and includes first and second end members, and a coupling. A first end of the first end member is a threaded shaft configured to be received in a mounting aperture of a power end unit. A first end of the second end member is a threaded shaft configured to be received in a mounting aperture of a fluid end unit corresponding to the mounting aperture of the power end unit. The coupling couples and extends the first end member and the second end member and may be removed therefrom without changing a relative position of the second end member to the first end member.

A coupler for mounting to externally threaded reinforcing bar for use in concrete construction, the comprising a body having a portion with an internal thread for engagement with the thread of the reinforcing bar, wherein the thread form at the inner end portion of the internal thread includes on one of its flanks an enlargement of progressively increasing extension, the enlargement extending towards an opposing flank of the thread to provide an increasing friction fit with the thread of the bar. Various embodiments provide the enlargement being only on a part of the face of the flank whereby the remainder of the face of the flank forms, in conjunction with the adjacent flank of the bar thread during tightening, a void for receiving material displaced during tightening.

A kit for mounting a wooden fixture comprising a body of wood, such as a handrail or a ceiling panel, on a supporting structure features a pair of brackets each for fastening to one of the wooden fixture and the supporting structure. Each bracket has a threaded surface which is threaded in an opposite rotational direction to the other bracket. That is, one bracket has right hand threading and the other bracket has left hand threading. The kit includes a coupling with a first surface portion which is threaded in the same direction as a first one of the brackets for mating therewith and a second surface portion threaded in the same direction as a second one of the brackets for mating therewith. The coupling is thus arranged for threadable mating with both brackets concurrently in a manner mounting the fixture but leaving a front face thereof uninterrupted.

An agricultural implement includes a chassis; a linkage carried by the chassis; a turnbuckle connected to the linkage and having a frame which includes a threaded hole formed therein and a non-circular region; and a latch pivotable about a fulcrum carried above the frame. The latch has a notch formed therein which is shaped to prevent substantial rotation of the frame when engaged with the non-circular region of the frame.

The invention relates in particular to a nut 1 for a clamping mechanism 10, a clamping mechanism 10 comprising a tie bolt 11 and two nuts 1, a vulcanizing press 20 comprising clamping mechanisms 10 and a support device 23.

The current invention relates to a load binder comprising an axially extending elongate, preferably tubular, member, two shanks, a first and second ratchet wheel, a first and second oscillatory handle; said member comprising end portions comprising inner screw threads in relatively opposite directions so as to accommodate said shanks which are correspondingly screw-threaded and which comprise distal ends, preferably eyes; whereby rotation of the member in one direction causes the distal ends to draw together and rotation of the member in relatively opposite direction causes the distal ends to spread apart; whereby said rotation of said member is effected by a ratchet mechanism which involves the provision of said first and said second ratchet wheel which are suitably secured intermediate the ends of the member and are rotatably mounted between mutually spaced first side members which project from said first and second handle.
