JOHN KING, OF CHICAGO, ILLINOIS.
ELECTRIC ANNUNCIATING PUSH-BUTTON.
SPECIFICATIOII forming part Of Letters Patent No. 494,337, dated March 28, 1893.
Application filed June 24, 1892. Serial No. 437,853- (No model.)
To all whom it may concern.-
Be it known that I, JOHN KING, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Annunciating Push-Buttons; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and letters of reference marked thereon, making a part of this specification.
The object of my invention is to provide a simple and practical electric annunciating push-button whereby when the bell rings a vibratory sound in the push-button will announce the fact to the person using the same.
In the accompanying drawings Figure 1 is a vertical central section of my annunciating push-button. Fig. 2 is a view from the bottom in line a: a: of Fig. 1. Fig. 3 is a top view of the base of the case or cover of my improved push-button with the contents and cap or top part of the cover removed. Fig. 4 is a top view of my improved push-button with the cap or top part of the cover removed.
Similar letters indicate like parts in all the figures.
In the construction of my, improved pushbutton A, is the button or push, adapted to be depressed for the purpose of closing the electric circuit.
B is the contact spring supporting the but ton A and is attached at one end to the insusupport the same, and being supported at the outer edge by the base piece G, forming part of the casing or cover G G.
F is the core of the magnet F, extending through the insulating head D.
H is the armature of the magnet F, and is preferably made of sheet iron in the form of a disk and attached at one side to the insulating head D, and having suflicient spring to retract the same from contact with the magnet core when the circuit is broken.
It is obvious that the manner of constructing the armature is not material, but that it may be in any suitable form adapted to the purpose.
9 g are the wires of the circuit.
G is the top or cap of the covering or case, and G is the base of the same, adapted to support the whole in position and to be attached to a wall, or wherever desired, by means of the screw lugs G G The operation of my improved annunciating push-button is as follows: The button A being depressed causes the spring B to connect with the contact point E, thereby closing the circuit and placing the electro-magnet F in circuit with the bell. The closing and breaking of the circuit occasioned by the action of the bell cause the armature H to be attracted by the magnet F and retracted synchronously with the movements of the bell, thereby producing a buzzing sound which will indicate that the bell is ringing, although it may not be within hearing distance.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In an electric aununciating push-button the combination of a base piece adapted to support an electro-magnet, an electro-magnet supported thereby in the line circuit, spring terminals mounted upon said magnet, a button for closing said terminals, and an armature for said magnet located within said base piece and adapted to produce a resonating sound when caused to vibrate by a make and break device in the same circuit, substantially as described.
2. In an electric annunciating push-button the combination of a base piece provided with a recess, and a shoulder adapted to receive and hold secure the insulating head of an electromagnet, and an electromagnet supported thereby in the line circuit; spring terminals mounted thereon, a button for 0105- name to this specification in the presence of ing the terminals, an armature for said magtwo subscribing Witnesses, net located within the recess of said base piece and adapted to vibrate synchronously 5 with an electric bell in the same circuit, substantially as described.
In testimony whereof I have signed my JOHN KING.
