Specification of Letters Patent.

Patented Nov. 26,1912.

Application filed February 4, 1911. Serial No. 606,557.

To all whom it may concern:

Be it known that I, LESLIE MCMINN, a citizen of the United States, residing at- Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Telephone-Bells, of which the following is a specification.

This invention relates to telephones and more particularly to telephone bells.

The invention has for one of its objects to provide an extremely simple and practical bell which gives out a pleasing sound which is at the same time loud enough to be used for telephone service.

Another object of the invention is the provision of a bell which includes a single gong and striking hammer, the gong having in ternal members spaced apart and between which the hammer moves to strike the memhers alternately.

lVith these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claim appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a perspective view of a telephone equipped with the improved bell. Fig. 2 is a sectional view through the gong to show the relation of the hammer to the in ternal striking members of the gong. Fig. 3 is a perspective view of the rear side of the gong.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawing, A designates an ordinary telephone or telephone ringing box which contains the usual electro-magnetically operated hammer 1 that is adapted to strike the single gong 2, the single gong being designed to take the place of the double gongs with a striking hammer disposed between them as are now in common use. This gong is attached to the box of the telephone by a post 3 and is so positioned that the two spaced parallel striking members 4 and 5 are disposed respectively on opposite sides of the hammer. These members 4 and 5 are extremities of a U-shaped structure which has its base 6 bearing on the internal surface of the gong and fastened rigidly to the latter by a rivet 7 or equivalent fastening. This U-shaped structure is disposed wholly within the hollow of the gong so as not to interfere with the latter being brought close to the ringer boX. When the hammer vibrates, it will alternately strike the members l and 5 and cause a very agreeable sound to be emitted which is loud enough to be distinctly heard within a reasonable radius. The base or bar 6 is curved to fit the curvature of the rim of the gong so that the U-shaped structure will have a large surface contact with the gong and at the same time snugly fit the latter and prevent a jingling sound which would otherwise result if the U-shaped structure were loose and did not snugly fit the gong.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.

Having thus described the invention, what I claim as new, is

The combination of a telephone including a bell hammer, a hollow gong disposed over the hammer and having a circular rim, a horizontally disposed Ushaped member mounted within the said gong, said U- shaped member having a central curved bar conforming to the curvature of the said rim and adapted to be attached to the inner wall thereof whereby to securely hold said member in an operative position within the said gong, said member being formed to provide In testimony whereof I afiix my signaspaced parallel arms projecting inwardly ture in presence of tWo Witnesses.
