Description: |
| Abstract:
This improvement consists of a combination of the common knob, having a neck or shank between, and smaller than the head, and foot of the knob, with a socket or plate either made wholly or having an edge or ring made of some soft metal capable of being set around the foot of the knob by turning in a lathe or otherwise without the application of heat. This socket is cast or otherwise made with a face, corresponding in form to that of the foot of the knob; and with a perpendicular edge or ring of soft metal around the outside of a depth somewhat greater than the thickness of the foot of the knob, the foot of the knob is then to be inserted into the cup, thus formed by the face, and *edge or ring of the socket, and the edge or ring is then to be turned down and let either in a lathe or otherwise close around the foot of the knob above the largest part of the foot so as to confine the knob closely and securely to the socket, or plate. If the use of the knob requires it, it may be made more secure from turning in the socket, by fitting the foot of the knob and the face of the socket together by a corresponding projection in the one and depression in the other, or by making the foot of the knob of some angular form with a corresponding hollow in the socket in the manner already practiced or otherwise.
Claim:
Our invention and improvement consists in The combination of the knob with the socket by means of the said edge or ring of soft metal when turned down, and set around the foot of the knob, and we claim nothing more. |
