TELEPHONE ATTACHMENT.
Specification of Letters Patent.
Patented Dee. 17, 1918.
Application tiled March 23, 1917. Serial No. 156,982.
To all wwm t may concern.'
Be it known that I, ROBERT C. GRoH, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Telephone Attachments, of which the following is a specification.
My invention consists of an improved light attachment for telephones, particularly adapted for use in connection with the automatic system to light up the number dial when the telephone is being used.
To this end my invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.
In the accompanying drawings forming a part of this specification,
Figure 1 represents a portable telephone instrument fitted with one embodiment of my invention.
Fig. 2 is a partial view of a battery support forming part of my attachment.
Fig. 3 is a plan view of the battery support partly broken away and showing the battery and connected wiring.
Fig. 4 is a diagrammatic view of the wiring.
Fig. 5 is a detail view of a light supporting bracket forming part of the invention, and 4 Fig. 6 is a sectional broken away view of a portion of the transmitter and light supporting bracket.
Referring to the drawings,
A represents an ordinary portable telephone instrument provided with the ordi- "nary transmitter 2, a number dial 3 forming part of the automatic system being supported upon the base of the instrument. In the form of my invention shown in Fig. 1 I provide a cabinet 4 preferably circular in shape to conform to the base of the telephone instrument and formed with an inwardly directed top flange 5 forming a support for the base. The cabinet 4 may be supported in connection with the base of the telephone instrument, as by means of clips 6 secured to the sides of the cabinet 4, the clips 6 extending upwardly and inwardly to fit over the base of the telephone instrument and one of said clips being loosely supported as by thumb screw 7 so as to be turned into and out of engagement position to allow the 1nstrument being arranged in position with the cabinet or removed therefrom.
Within the cabinet 4 I place a dry battery 8 for supplying the electric current, said battery being removably held in position as by clips 9. Supported upon the bottom of the cabinet in position to engage with the contacts 10 and 11 of the battery are electrical contacts 12 and 13. From the contacts 12 and 13 wires 14 lead through a suitable covering to the electric light fixture 15. The fixture 15 consists of the usual incandescent globe -16 and a chain 17 for closing the switch 18, illustrated diagrammatically in Fig. 4, to send the current through the filament of the globe. The light fixture is supported from the transmitter mouth piece by means of a bracket 19 which is formed with a collar 20 to fit around the inner end of the mouth piece, as shown in Fig. 6 and with a threaded lower end 21 to be secured in the light fixture. The cords 14 are supported alongside the standard of the telephone instrument by means of spring clamps 22 which [it around the telephone instrument as shown in Fig. 1 and are formed with outwardly extended portions 23 receiving the wires 14.
The pulling of the chain 17 in the form shown in Fig. 1 will cause the current from the battery 8 to pass through the lamp lilament throwing the light directly down upon the dial 3 to render the operation and reading of the dial 3 more easily accomplished. I secure a construction which may be supported in connection with the ordinary automatic instrument without the necessity of any changes in the construction of the instrument itself. My improved method of supporting the lamp from the inner end of the mouth piece forms a convenient and quickly carried out method of supporting the same, and also brings the light at the proper position in reference to the dial.
The many advantages of my attachment in connection with the widely adopted automatic telephone, with the many dificulties of actuating and reading the dial where the telephone has to be used in the dark, will be manifest.
I claim- 1. In combination with a telephone instrument formed with a base, a standard and a mouthpiece supported by said standard, a
cabinet removably supporting said base and ing electric light removably supported from containing a source of electrical energy, a sald mouthpiece, wires leading from saidv depending electric light removably supsource of electrical supply to said light and 15 ported from said mouthpiece and a connecmeans detachably supporting wires upon tion between said source of electrical energy said standard.
and light. In testimony whereof I afiix my signature 2. In comblnatlon wlth a telephone lnstruin presence of two witnesses. ment formed with a base, a standard and a ROBERT C GROH mouthpiece supported by said. standard, a A
cabinet containing a source of electrical Witnesses:
supply, means detachably supporting -said. BEATRICE BROWN, telephone base upon said cabinet, a depend- H. S. JOHNSON.
