ILLUMINATING DEVICE FOR- TELEPHONE-S.

Application filed April 27, 1923. Serial No. 635,063.

erably of copper, and which extend around the dial post 13. To prevent short circuitm of these brushes by the metallic finger dial 13 a disk of insulating material 14 is interposed therebetween, and purpose an insulating ring 12 is placed between the brushes themselves. From Figure 2 of the drawing it will be seen, the telephone to which the invention is attached is equipped with a number dial 15 of insulatin material; however, should it be desired to attach the device to a a metallic number dial, it would only be necessary to place another disk, similar to the disk 14, below the brushes l and 11. Electric bulbs 11 extend through apertures in brush 1(), through insulating ring 12, beneath the brush, and contact with brush 11. on post 13. It will be readily seen that the current must pass through both connecting wires a--a, before the bulbs will be lighted.

The transmitter 3 is shown, and below it the receiver hook 4, supporting the receiver 5, as the receiver is lifted from the hook, the operation shown in Figure 3 takes place, namely the contact point on the receiver hook 4, allows spring contact 6 to move forward, and contact with member 7, thereby making a circuit through wires arr-a and the battery 8. As this circuit is made, it sends a current through wires ara, to brushes 11 and 11, and through them to light bulbs 10. 15 represents the porcelain lettered dial plate.

It should be understood that a suitable This invention relates to telephone equipment, and refers to an illuminating means in attachment to telephones of the automatic type, whereby the numbers on the dial may be rendered visible when the receiver is removed from the hook.

An object of the invention is the provision of an electric light or lights mounted on the dial post and connected by suitable wiring to the receiver hook wiring, so that when the hook is lifted, the circuit to the lights will be made, and same will illuminate the dial, and when the receiver is hung up the lights will be extinguished.

Another object is to provide a device of this character that may be attached readily and quickly to an automatic telephone, and whose operation and construction is simple and durable.

Another object is the provision of a suitable switch adapted to cut oif the current to the lights when it is not desired to use same.

Other objects and features will be set forth in the following description, taken in connection with the drawings attached hereto, as follows:

Figure 1 shows a side elevation of an automatic telephone, with the illuminating device in attachment thereto.

Figure 2 represents a cross-section of the dial, showing the construction of the illuminating dial on the dial post.

Figure 3 shows a detail sectional view of 35 the receiver hook, showing the contact made when same is lifted.

Figure 4 shows a side elevation of an automatic telephone with the invention attached, the dial and the elements of the invention in cross-section, and part of the telephone broken away to show the manner of wiring to the lights on the dial post.-

Figure 5 shows a top view of the dial with the invention attached, part being broken away to show the vdetail of construction of the invention.

It should also be method of construction shown as it involves less changing telephone structure, and the additional structure.
