ELECTRICAL PUSH-BUTT ON.
SPECIFICATION forming part of Letters Patent No. 540,949, dated June 11, 1895.
Application filed January 24, 1895.
Be it known that I, EDWIN A. CLARK, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and Improved Electrical Push-Button, of which the following is a full, clear, and exactdescription.
The object of the invention is to construct a simple, compact and inexpensive electrical push button, which may be inserted in a circular cavity formed by a bit in wood or by a drill in stone.
The invention consists in a ferrule having an inwardly turned flange or fillet, a plug of insulating material carrying two contact points, a metallic cap having flaring sides inserted in the ferrule and adapted to touch the two contact points, and a spring resting cap outwardly away from the contact points, all as will be hereinafter more fully described.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of my improved push-button. Fig. 2 is a vertical transverse section. Fig. 3 is a horizontal section taken on line 3 3 in Fig. 2. Fig. 4 is a vertical transverse section showing the cap depressed and forming contact with the two contactpoints, and Fig. 5 is a vertical transverse section of a'modified form.
The ferrule A, which'is formed of metal or other suitable material, has an inwardly turned flange or fillet a, and in the end of the ferrule thus contracted is inserted a cap B, having flaring sides. The smaller end of the cap projects through the fillet at the end of the ferrule, while the larger end is of greater diameter than the opening in the ferrule. In
the larger end of the ferrule is inserted a plug 0, of insulating material, in which are inserted the contact points I) which are to be connected with the circuit wires. In the ,Se1'ia.lI Io. 536,072. (No model.)
present case the contact points are formed by the cap 5 is depressed, as shown in Fig. 4, it
touches both contact points, and the circuit is completed through the cap. When it is released the spring D pushes the cap outwardly and breaks the circuit. 7
In the modification shown in Fig. 5, the body 0' of insulating material is recessed to receive the spring D, and a ring cis inserted in the rabbet in the outer end thereof for receiving and holding the cap B. The action of this form of push button is the same as that already described.
' Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A push button, formed of aflaring frustoconical cap of conducting material forminga spring receptacle, a ferrule having a fillet for engaging the larger end of the cap, a body of insulating material, contact points inserted therein, and a spring resting on the body of insulating material and extending into the cap, substantially as specified.
2. A push button formed of a casing having an inwardly projecting rim,.a flaring frustoconical metallic cap engaged by the rim, contact points held in the path of the cap, and
aspring extending into the cap for automatically separating the cap from the contact points, substantially as specified.
