ELECTRIC PUSH-BUTTON.
SPECIFICATION forming part of Letters Patent No. 358,109, dated February 22, 1887.

- tion.
This invention relates to certain new and useful improvements in push-buttons for opening and closing electric circuits by which to operate electrical calls or signals; and it con sists, substantially, in such features of construction and combinations of parts as will hereinafter be distinctly described, and pointed out in the claims.
In inventions of this character it is desirable that the outer cap or cover which incloses the circuit-closing devices shall be removable or detachable from. the supporting-base, by which ready access can be had to the interior for the repair and adjustment of such devices; and heretofore in making this provisionit has been observed that thecost of the additional labor required in the formation or manufacture is, in a commercial sense, rather incompatible withwhat the completed article realizes when placed on the market. Heretofore it has been customaryinsomeinstances either to mold or cast a thread around the base pr0-' jection and similarly provide the interior of the rim of the cap with acorresponding thread, by which the latter. is secured or screwed to the former, or to form the cap and base pro jection with corresponding teats and grooves to form an interlocking connection when united. The operations necessarily resorted toin the manufacture of push-buttons embodying these constructions are found to be more or less tedious and expensive, and as a consequence thereof the cost of the completed article is rendered correspondingly great.
The object of my invention is to provide a push-button having a removable cap or cover which shall be cheap in first cost, simple in construction, and one which shall require little or no skill in the manufacture thereof.
Referring to the accompanying sheet of drawtop or plan view with the cap or cover removed, and Fig. 3 is a view thereof in perspective showing the cap in place.
In carrying my invention into effect I provide a base, A, of wood or other suitable'noir 5 5 conducting material, and form therewith or attach thereto a centrally-arranged projectlon, a, the usual holes, b b, being formed through both the base and projection for the passage of the Wires or other electric conductors,which 6:)
are properly connected to the spring-contact strips or circuit-closing devices 0 c. In constructing the base A, I either form the PIOJGO- tion a thereon as an integral part, or I secure to the top of the base Aaseparate or sub-base B, into the rim of which I form or indent a corresponding thread by the usual spinning or swaging machine process, and thus, it will be seen, the push-button case is quickly manufactured or fitted up. When the cap is thus fitted, it is removed and the proper attachment of the circuit-closing devices effected, whereupon the cap is replaced and the device 1s ready for use or connection with the wires compr1sing the circuit. The said metallic cap is provided with a central opening, f, through which the button 9 works to compress or bring the strips 0 0 into electrical contact.
It is evident that, instead of forming the base with a projection, I may simply employ aper fectly fiat base with a thread formed or turned in its outer side, and then conform the cap thereto; but I prefer the construction here1u shown.
It will be seen that a push-button manufac tured in accordance with my invention possesses characteristics which are valuable in a commercial sense, and in addition to its points of cheapness and simplicity it will be seen, also, that the cap or cover nay be much more readily conformed toornamental configura- I0 In either case I turn a continuousscrew- 7o tions or designs than in former inventions of 3. The combination, with the base having an analogous character. projection a, formed with a screw-thread on 15 Having thus described my invention, what I its exterior, of a metallic cap or cover fitted to claim as new, and desire to secure by Letters such projection and having a corresponding 5 Patent, is thread, substantially as described.
