SPECIFICATION forming part of Letters Patent No. 777,106, dated December 13, 190 1.
Application filed May 17, 1904. Serial No. 208,398. (No model.)
To (ZZZ whom, (it may concern:
Be it known that I, HENRY FnANcIs Knit, a
citizen of the United States of America, and a resident of Bronxville, in the county of Westchester and State of New York, have invented a certain new and useful Casing for Electric Push-Buttons,of which thelj'ollowingisa specification, the same being a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to articles constructed and arranged to complete the circuit of an electric bell or other electrical organization by pushing or pressing the same; and it has for its object the production of an electric push-button consisting primarily of a base and of a metallic cap or cover therefor and means whereby the two may be snapped or hooked together in lieu of screwing the two together or holding the same in rigid engagement by means of securing devices, as screws, 850., the whole being neat and ornamental in appearance and economical in construction.
With this object in view the invention consists in certain novel features of construction and combination and arrangement of parts, all of which will be hereinafter described, and specifically pointed out in the drawings which accompany and form a part of this specification, in which Figures 1 and 1 represent front and side elevations of one member of my push-button. Figs. .2 and 2 are front and side elevations of the other member, consisting of the cap or cover therefor. Fig. 3 is a transverse section of a complete push-button constructed according to my invention. Figs. 1 and 1 and 5 are respectively front and side elevations and a plan view of another push-button base embodying my invention. Fig. 6 is a view in detail of my push button back piece. Fig. 7 is a plan view of another pushbutton constructed according to my invention. Fig. 8 is an elevation of the same, partly in section, with the cap or cover raised from the base. Fig. 9 is a view in section,
section through the cover.
I are respectively a plan view and a view in section of a base-plate for the push-button, and Figs. 13, 14, 15 are views in section of other bz'tse-plates and caps or covers therefor constructed according to my invention.
Like letters of reference indicate like parts in all the views.
Referring particularly to the drawings, A denotes one member of my push buttonnamely, the base which may be struck up out of metal and provided with a central indented portion or recess formed by the shoulders A. This central indented portion or recess is preferably raisedthat is to say, it lies in a plane above the plane of the bottom of the outer edge or rim of the base. The base preferably has a recessed portion, as a groove or slot, formed in the edge of the same, as a, or an inclined groove or slot, as 119, of the base A, and in either case a recess or slot may be formed in the top face of the base, as (.4
My cap or cover 1), constituting the other member of my push-button, is preferably formed of sheet metal and has an indention d, projecting from the said cap or cover, constructed and arranged to engage the recesses 11/ or a for the purpose of snapping or booking the members of my push-button together.
\Vithin the indention or depressed portion of my base lying between the shoulders A, l locate my push-button back piece B, upon which are mounted the spring circuit brcaking or closing lingers I) I), the same being secu red to the said back piece by means of screws B each preferably provided with an orifice I), througl'i which the circuit-wire may be passed and thereby twisted around the said screws.
1n the push-button shown in Figs. 7 to 12, inclusive, A denotes my base, preferably constructed of insulating material and ordinarily provided with an undercut or in wardly-turned beveled edge or rim (15, preferably extending entirely around the edge of the said base-plate. The said plate A also preferably has a centrally-depressed portion A or indentation to retain the {)L'lSll-lJlltllOl] back piece 15, whereby the shoulder a is formed, the bottom face of or hooking the two members together.
which depressed portion may or may not be cut out, as on the dotted line a in Fig. 11, so as to provide an opening through the same. I prefer to place within the said depressed portion A of the base-plate A a push-button back piece B, constructed and arranged to support the spring-circuit-breaking fingers Z) Z), formed in the ordinary manner, one of which spring-fingers serves to support the knob or button C. Althougl1,if desired,the parts A and B may manifestly consist of a single plate, serving both to engage the push-button cap or cover and to support the spring-circuit-breaking fingers, I sometimes form one or more recesses or slots (4 around the outer periphery of the base-plate A, for the purpose hereinafter set forth.
The preferably sheet-metal cap or cover D is formed with a central orifice (Z for the button G and a depending portion, as the edge or outer rim d, which edge preferably has one or more indentions formed on the outer side of the same, which causes a corresponding number of projections or hooks (Z to stand out from the opposite face of the said edge, which projections or hooks when the said cover or cap is applied to the base-plate may be either snapped over the outer edge a of the baseplate A or passed through the recesses or slots (4 and then wedged within the groove formed by the recessed beveled edge beneath the baseplate by turning the coverD around for alittle distance. The projections or hooks formed on the cap or cover thus enter the recessed portions formed beneath one edge or rim of the base-plate or bottom member of the pushbutton and are held from being moved outwardly from the said button by means of the said recessed edge or rim.
Manifestly the projections or hooks may be formed on either side of the inner rim of the caps D and D, as at and (Z in Figs. 13 and 1 1, which projections may be engaged either with the base plate A or the pushbutton back piece A of the base A as desired, my invention in this particular consisting of means whereby the cover and base of the push-button may be engaged by snapping It is likewise obvious that the base A may be made so as to be provided with the projections 66 in Fig. 15, and the cap or cover 1) may be constructed with a beveled edge (Z30, constructed and arranged to be snapped over the same.
As it is evident that many changes in the construction, form, proportion, and relative arrangement of parts might be resorted to without departingfrom the spirit and scope of my invention, Iwould have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor, and that IVhat I claim as my invention is 1. In a push-button, a knob or button, a base having a central recess formed by shoulders A, and also recessed portions formed beneath the edge or rim of said base, an insulated push-button back piece B, to rest in the central recess, circuit-changing springs to rest on the latter, and a cap or cover having projections to engage the said peripheral recesses and to hold the knob against one of the circuit-changing springs.
2. In a push-button, a knob or button, a base having a central recess formed by shoulders A, and also recessed portions formed beneath the rim or edge of said base, an insulated push-button back piece B, to rest in the central recess, circuit-changing spring to rest on the latter, retaining-screws therefor provided with orifices, and a cap or cover having projections to engage the said peripheral recesses and to hold the knob againstone of the circuit-changing springs.
3. In a push-button, a knob or button, a base having a central recess formed by shoulders surrounding an interior opening and also recessed portions formed beneath the edge or rim of said base and extending upward through the upper face of the same, an insulated pushbutton back piece to rest in the central recess, circuit-changing springs to rest on the latter, and a cap or cover having projections to engage the said peripheral recesses and to hold the knob against one of the circuit-changing springs.
In testimony of the foregoing specification I do hereby sign the same, in the city of New York, county and State of New York, this 19th day of April, 1904;.
HENRY FRANCIS KEIL.
