Abstract: A joint for fabricating rattan furniture particularly joining two rattan poles to form a T-shaped connection which includes forming a saddle at the end of one pole, forming an axial hole in said one pole, locating an internally screw-threaded sleeve in the hole, fixing the sleeve in the hole by passing a pin through the pole and the sleeve, passing a bolt through a diametrically disposed hole in the other pole and screwing the bolt into the sleeve to seat the other pole on the saddle.

Abstract: A disjoinable assembly designed for connecting of piston with piston rod in ngines and machines, this assembly being particularly suitable for use in compressors, includes an insert [4] and a bolt connector [3] mounted in the said insert, said connector co-operating with piston rod [2]. The insert [4] is U-shaped in cross-section, it has preferably the form of a cylinder with bottom [8] at one end, said bottom having a hole [9], and it is provided with bearing surfaces [12] in the form of splineways [10] or splines [14] , said bearing surfaces [12] being matched with bearing surfaces [13] made in the form of splines [11] or splineways [15] on the piston rod [2] . The insert [4] is fixed in position relative to piston [1] and piston rod [2] by means of dogs [20] , said dogs being formed by bending the sections of rim [16] toward one or more sockets [6] made in piston [1] , and by bending the other sections of the said rim [16] toward one or more sockets [17] made in connector [3].

Abstract: A device is disclosed for locking a first screw, or other rotatable part, within a cavity in an impeller. The screw incorporates a cavity containing a spring. A second screw is positioned in the head of the first screw in such a way that it may be used to force the spring into resilient cooperation with the surrounding surface. The first screw is locked thereby to the surrounding surface and is prevented from threading-out under certain heavy load conditions. This development is especially useful for locking an impeller to a pump shaft.

Abstract: The wheel safety lock comprises a hollow hub cylinder which is engagable on to a wheel hub, a diameter web and means disposed on the wheel lock for retaining the hub cylinder on a wheel hub. Means for locking the hub cylinder to a wheel hub include holes in the diameter web through which fasteners may be engaged into the wheel hub, threads on the interior terminal sidewalls of the cylinder hub, and a mechanically actuated diameter web assembly having movable lug arms which are engagable with recesses in a wheel hub.
