The object of this invention is to provide an improved dial for use on an ,aut omatic telephone, and especially designed to facilitate the use thereof at night. I

A further object is to provide a special construction including a plurality of split discs, each having laterally extending'ears adapted to project on opposite sides of the finger hook, one of the discs carrying illuminated characters, and the other being transparent and acting as a protecting device, the two discs when secured together being mounted below the usual element having finger holes therein.

. WVith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claim, without depart ing from the spirit of the invention.

In the drawings forming part of this application,

Figure 1 shows the construction in top plan.

Figure 2 is a view in front elevation.

Figure 3 is an elevation of one of the split discs detached.

Figure 4 is a section on line H of Figure 3.

Figure 5 is a section on line 5-5 of Figure 3.

A disc is rovided with finger holes ll, and is mounte in spaced relation with reference to the special discs 11 and 12 herein disclosed. A finger hook 13 serves the usual purpose, and the discs" are so formed that they have a particular relation with reference to the portion 14 of hook 13 and constitutin the mounting member thereof.

The isc 11 has the form of a split ring, and includes the cars 15 and 16, each provided with an eyelet hole 17 for the accommodation of eyelet 18, to be applied through both discs, as indicated below. This disc 11 is of celluloid or other transparent material, and acts as a protecting device for disc 12, immediately ad acent thereto, and carryme; the numbers or characters to be read. Disc 12 may also be of celluloid, and the characters 12', thereon are coated with a radium compound, or are formed thereof. Disc 12 is also provided with ears adjacent to the split ends, the ears corresponding with elements 15 and 16 of the other disc, and apertures being provided for eyelet 18.

Ears 15 and 16 of the discs therefor register, when connected by eyelet, and these elements 15 and 16 pass on opposite sides of the finger hook 13 and are retained by passin .a short length of copper wire or other sul'ta le securing device through the eyelet. The combined discs 11 and 12 are therefore securely retained, and may be applied with the least possible difliculty, the "split portions facilitating the work of placing the device in position with reference to the portion 19 of the instrument. 'iihe device may likewise be readily detached, and removed to another instrument, if desired.

What is claimed is:

An attachment for an automatic telephone including an apertured finger disc, and a finger hook, said attachment comprising a plurality of split discs having laterally extending ears adapted to project on opposite sides of the hook, one of the split discs carrying illuminated characters, and the other split disc constituting a transparent protecting element, and means for connecting adjacent ears of the discs, these ears overlying each other, and means connecting the oppositely located ears and passing around the hook.

In testimony whereof I afiix my signature.
