UIT@ SATS VINCENZO IMPARAIO, 0F LONG ISLAND CITY, NEW YQRK.

DOORBELL.

Application led .Tune 22,

To aZZ whom t may concern:

Be it known that I, VINCENZO IMPARATO, a subject of the King of Italy, and resident of the cit of Long Island City, county of Queens, tate of New York, have invented certain new and useful Improvements in Doorbells, of which the following is the specification.

The device, the subject of this invention is a door bell for ordinary use, the particular objects, however, are to provide a bell that will give a long, clear, multiple stroke alarm, somewhat similar to the alarm of an electric bell.

Another object of the invention is to provide a bell similar in appearance and operation to a spring operated bell, but, one wherein the spring will not be required to be re-wound from time to time.

Another object of the invention is to pro` vide a bell that may be readily placed upon doors or casings of varying thicknesses, without difliculty and one wherein the securing means is simplied to a plurality of wood screws and where it is only necessary to cut a narrow slot through the door or casing, to allow the bell to be secured in operative position.

These and other objects of the invention will be fully set forth as the specification progresses and the accompanying drawing should be referred to for a. complete understanding of the specication which follows:

In the drawing Fig. 1, is a front elevation of the escutcheon and bell operating means.

Fig. 2, is a side elevation, partly in section of my device in operative position.

Fig. 3, is a back elevation, partly fractured to disclose the operative mechanism.

Fig. 4, is a perspective view of the hammer.

Similar reference numerals indicate like parts in all the figures where they appear.

At 5, I show a suitable support for my bell. This support may be a door, door casing or otherwise and of any desiredI thickness, as I have provided means to be later described for allowing a wide adjustment of my bell.

Secured on the outer side of the door, the side from which the alarm is to be given is an escutcheon or plate 6, which may be more or less decorative and which should be provided with a plurality of decorative securing screws as shown at 7 and 8. The plate 6 is 1922. serial No. 570,118'.V

provided with an aperture 9, from which projects a lever member 10, having an enlarged and preferably decorated hand or finger plate 11.

Upon the back of the escutcheon or plate 6, I arrange a plurality of lugs 12 and upon a pivot 13, passing through these lugs, the lever 10 is mounted. A pin 14 secured in a pivot lug 15 on the lever 10, extends through the door and through the aperture 16 therein, this pin serving as an operating member or power transmission means'to the bell mechanism arranged at the other side of the door or casing.

lIhe bell proper comprises a base plate 17 having a projecting stud 18, upon which is supported a toothed sector 19. The sector 19 having a projection 20 provided with an aperture 21 in which the pin 14 is free to operate.

Upon the stud 18, I also arrange a coiled spring 22, one end of which is secured to the stud 18 as shown at 23 and the other end being provided with a loop 24, which engages a pin 25 upon the sector 19.

Adjacent to the teeth 26 of the sector 19, I arrange a bridge member 27 and I pivot between the bridge mmber 27 and the base 17, an escapement or hammer operating mechanism as shown in Fig. 4, where the hammer is indicated at 28, its Supporting arm at 29, the teeth of the escapement at 30 and 31 and the pivots at 32 and 33 and it will be understood that the hammer arm 29 is secured to the escapement member 30-31 or to a shaft upon which this mem ber is mounted.

The operation of this device will be readily understood from the description of its construction. Lifting the free end of the lever 10 will depress the projection 20 of the sector member 19 and the release of the lever 10 will allow the spring 24 to return the sector member and the lever 10 to the position shown. Movement of the sector in either direction will agitate the escapement member by the engagement of the teeth ofl the sector with the projections 30 and 31 of the escapement and the hammer 28 being properly located will hit the bell once for every tooth in the sector, regardless of the direction in which the sector shall be moved.

The length of the pin 14 will allow my device to be used on doors of different thicknesses. Obviously the position of the escuteheon may be reversed and other modiications may be inade Within the scope of the appended claim Without departing from the principle or sacrificing the advantages of the invention.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is as follows A doorbell comprising an escutcheon, a lever pivoted thereto, a pin projecting Signed at the city, county and State of 15 l New York, this 3rd day of June 1922.
