SPEGEFEGATION forming part of Letters Patent. No. 325,463, dated September 1, 1885.

application filed July 11, L884. (No model.)

To all whom it may concern:

Be it known that I, HENRY E. W'AITE, a citizen of the United, States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Annunciators, of which the following is a specification.

My invention relates to electric ann unciators, and has for its object to construct a simple, cheap, and effective annunciator that will occupy butlittlc space andbe easily made and placed in position, and at the same time be accessible for inspection and repairs; and to this end my invention consists in an annunciator constructed and arranged as more particularly pointed out hereinafter.

Referring to the accompanying drawings, forming part of this specification, Figure 1 is a side view of the annunciator. Fig. 2 is an end view. Fig. 3 is a section of a board containing several annunciators in position, and Fig. 4 is a view of one application of my invention.

One of the chief objects of my invention is to construct an annunciator that is compact and powerful, and that may be fitted to a board by very little tooling, and that of the simplest nature; and to attain these I form a magnet, preferably of the horseshoe type, and upon the core a is placed a coil or helix of insulated V wire, I), which may be wound upon an insulating or nonmagnetic bobbin, 0, of hard rubher or other suitable material. From one end of the core, either integral with it or fastened by any suitable means, springs the other pole or extension of the magnet d, and this is fiat tened and preferably curved, so as to fit closely over thehelix,and theend may besecured thereto in any suitable manner, if desired. To the front end of this extension is pivoted, or otherwise suitably fastened, the bar or strip 0, of some suitable material, to form or to carry the armature to the core a of the magnet. One mannor of attaching it is shown in the drawings, and consists in providing the extension at with two projections, 1 2, between which the bar is hung. The upper end of the bar may be tapered to a point and be slightly bent for ward, as shown, and the lower end may be circular in form and receive the number or character designating the drop; or the plate may be of sheet metal struck up and have a flange or rim for the reception of a card or plate bearing the designating character.

A shutter or drop, it, is secured to the magnet or coil in such a manner as to normally rest against the upper end of the bar c when the magnet is not energized, that shown consisting of a plate secured to the bobbin 0, projecting forward and forming a hinge-joint, f, upon which the shutter freely swings.

If preferred, the designating character of the annunciator may be placed on the inside :of the drop, as shown in dotted lines, so as to be exposed to view when itis down, as shown in Fig. 2.

Projections or lugs g 9 may be made on the front edge of the bobbin, or a plate or band maybe attached to the magnet and be provided with holes for the reception of screws to more securely hold the annunciator in place. By this construction it will be seen that the annunciator is substantially cylindricalin shape; and this is an important feature of my invention, as the annunciator may be fitted in place in the board or other position by simply boring a cylindrical hole therein.

In Fig. 3 I have shown one manner of arranging and attaching the annunciator, in which A is a board of a suitable thickness, in

which are formed sockets or holes,which may be bored, the outer one, m, being slightly larger than the inner one, a, and the annunciator magnet may beinserted therein, as shown, and secured by screws a, passing through the lugs or projections g 9 into the base of the outer hole; or the inner hole or socket may be of such a size that the magnet will fit closely and require no additional fastenings.

The rear of the socket may be open, so that the line-connections can be made, the wires preferably being held by screws 0 0, and a plug, 19, may be used to close the opening to keep out dust, 8m, but to be easily removed if access is desired to the magnet.

The annunciator-drops may have suitable lugs or projections on their bottom parts, and suitable rods may be operated by a crank or lever to restore all the drops simultaneously to their normal position in the usual manner; or each drop may be restored by hand.

The operation of the device is evident from the above. wire 1, passing through the coil, energizes the A current coming over the linemagnet, causing the armatures e to be attracted, when the'upper bent end will force the drop outwardly, causing it to fall and disclose the designating character.

By this construction it will be seen that I produce a very economical device, as all the parts may be struck out or forged, requiring little or no tooling, and they may be made very light and at the same time effective, and being so compact they occupy verylittle space. In Fig. 4 I have shown atype of switch-boards having a group of annunciator-drops on the board A, and a corresponding series of connectors on the board B, by the use of which a very compact switch-board may be produced.

It is evident that a single bar-magnet may be used in place of the horseshoemagnet, and the armature be secured to the bobbin or other part; but by the use of the horseshoe-' magnet a more powerful and efficient device is obtained.

WVithout limiting myself to the precise details of construction, which may be varied without departing from the spirit of my invention, what I claim is- 1. An electric annunciator consisting of a horseshoe-magnet having a bobbin and coil on one pole, the other pole being flattened and bent so as to lie in close proximity to and follow the contour of the coil as set forth.

2. An electric annunciator consisting of a magnet, a bobbin and coil, one pole of the magnet being flattened, and an armature or armature-lever connected to the end of the flattened pole, and a pivoted drop adapted to be operated by the armature, as set forth.

3. In an electric annunciator, the combination, with the magnet and coil, of an armature pivoted to the flattened end of the magnetcore, and consisting of a broad flattened end for the reception of the designating character, and a shutter or drop adapted to be operated by the armature, as set forth.

4. An electric annunciator consisting of a horseshoe-magnet having a bobbin and coil on one pole, the other being flattened and arranged in proximity to the coil, an armature or armature -lever pivoted to the flattened pole, a shutter or drop pivoted toa support connected to the bobbin and adapted to be op- U erated by the armature-the whole being ar ranged so as to be substantially cylindrical in form, as and for the purpose set forth.

5. The combination, with a board havinga cylindrical socket, of an annunciator adapted to and placed within said socket, and a plug closing the end of the socket, as and for the purpose set forth.

In testimony whereof Ihave signed my name to this specification in the presence of two sub scribing witnesses.
