Definitions
- This invention relates to a lock-nut consisting of a U-shaped stirrup in which the threaded holes of two U-limbs are displaced parallel to one another.
- the lock-nut has given very good results in practice and has been found very resistant to vibration.
- the lock-nut has been especially effective when the force was applied near to the web connecting the two U-limbs. The point of application of the releasing force, however, depends on chance and cannot be controlled.
- the present invention is to improve such a lock-nut in such a manner that the point of application of the force which tends to 5 release it will be directed to a point close to the web.
- the axis of the thread cut in the holes of both limbs is slightly inclinedtoivards the lower edge.
- a further advantage of this construction of the lock-nut lies in the fact that a more 0 secure adhesion of the thread holes to the bolt, such as would arise on account of the displacement of the holes, is obtained even when the threads of the bolt and the locknut have reached or even fallen below, or exceeded, the minimum and maximum values respectively of the permissible tolerances.
- the lateral play which would occur between the bolt and the lock-nut, is avoided at least in part by the inclination of the axis to the thread.
- Fig. 1 shows a part of the device on an en'- larged scale
- Fig. 2 is a side elevation and plan of the device. 7
- the lock-nut consists of two parallel U- limbs a and b which are connected together by a web a.
- the two limbs have holes (1 and e in which continuous threads are cut.
- the locknut is placed on an oblique surface of a support U.
- the angle of inclination a of this oblique surface corresponds to the inclination of the axis of the thread.
- the lock-nut must be placed on the support in such a manner that its web is .at the lowest part so that the inclination of the thread runs towards 7 the lower edge 'of the axis X-X of the thread.
- a tool S of suitable construction is used for cutting the thread.
- the nut is removed from the support and its two holes are displaced by twisting the limbs. The displacement is eiiected in a direction parallel to the web.
- Fig. 2 the device for cutting the thread is shown on a smaller scale. It will be seen that a clamping cheek B, which can be displaced by means of an eccentric E and which engages the nut, is arranged on the support U.
- a lock-nut consisting of a U-shaped stirrup in which the threaded holes of the two U- limbs are displaced parallel to one another, characterized by the feature that the axis of the thread in the holes of the limbs is inclined towards the lower edge of the web oining the two limbs so that when the nut is screwed up it first touches the workpiece or the supporting nut at the side nearer to the web.
