Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed August 21, 1915. Serial No..6,598.

in which thel electric lamp is supported on the sound box of the phonograph in position to throw the light upon the needle and the record, and provide improvedv means` for closing the electric circuit to cause the illumination of the lamp at any time desired, either when the needle is against the record or when the box is elevated from the record.

A further object is to provide improvements of the character stated which can be manufactured and sold at a reasonably low price without in any way altering the conistruction of the phonograph.

lith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts will be more fully Y hereinafter described and pointed ont in the claims.

ln the accompanying drawings: Figure l is a View in side elevation partly in section illustrating my iml rovernents. 2 is a top plan view showing the free end of the tone arm and parts carried thereby, and vFig. 3 is an enlarged View in section on the line 3-3 of Fig. 2. I

- l represents the box of a phonograph ha ving a turn table 2 thereon supporting a record disk 3. Y

4 is the pivoted tone arm which is secured to the box by a socket member having screws 6 holding the same in place.

7 is the ordinary goose neck pivotally connected to the free end of the sound arm, and carrying the ordinary sound box 8, to which the needle arm 9 is connected, and to which latter the needle or stylus i0 is cured in the ordinary way.

rl`he several parts of the sound box 8 are secured together by screws ll, and certain of these screws ll are utilized to secure my improved bracket l2 to the side of the box 8. This bracket ll is curved throughout a portion ofy its length conforming in shape to the curvato. t the box, and at its free end is provided with a lamp socket 13. The socket 13 is insulated from the bracket bv a ring lei, but the electric lamp l5 supported 1n the socket has one pole thereof electrically connected Ywith the bracket for a purpose which will be hereinafter described..

A clamp 1G is secured around the tone arm -land is insulated from the tone arm by a ring 17. The clamp i6 `is provided on its upper face with parallel ears 18, in which a switch arm 19 is pivotally mounted. This switch arm 19 is normally held in elevated position by a spring 20, and is adapted when forced downwardly to engage the end of the tone arm fl. i

in the box l, I locate an electric battery 2l to which wires 22 and 23 are connected. lhesewvires 22 and 23 are preferably of the insulated type, and are projected through one off the screws 6, the latter having a Central longitudinal bore 24 for the purpose as shown clearly in Fig. l. lVire 22 is electrically connected with the clamp 16, while wire 223 is electrically connected to the I socket 4bracket l@ operateY as conductors to close the electric circuit, and cause the illumination of the lamp.

lWhen it is desired to lightthe lamp for a short time, the arm 19 is pressed downwardly until its lower end contacts with the tone arm, and if for any reason it is desired to maintain the light for any con-v siderable length of time, the switch arm can be thrown backward to the position shown in dotted lines, where it will remain by its own weight, and maintainA the electric circuit closed.

As shown in Fig. l, the lamp isin such position that it directs the light upon the record 3 where it. is engaged by the needle l0, and this is of great importance as it enables the operator to readily find the groove in the record.

Vil-hen il, is desired to insert a new needle, the goose neck is thrown backward, as is' customary, so that the needle is uppermost, and while in this position, the electric circuit is readily closed as above described, and the lamp will throw the light upon the free end of the needle bar so that a needle can be easily placed in position.

Y It is a well known fact that records, parimportance, as it permits all manipulation of the phonograph with the necessary light whenever desired, yet during the playing operation the arm remains dark.

While I have referred to the source of electricity as a battery within the box, it is of course to be understood that I may utilize any source of electricity to be had.

Various slight changes might 'be made in the general formand arrangement of parts described without departing from my invention,'and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isz.

1. The combination with a phonograph having a tone arm, a goose neck at the free end ofthe tone arm, and a sound box at the free end of the goose neck, of an electric lamp on the sound boX, a pivoted switch arm insulated from the tone arm and movable to either side of its pivot, said switch arm adapted when moved downwardly against the phonograph from either side of its pivot to close an electric circuit to the lamp, and a. spring Yholding the switch arm elevated in one of its positions out of contact with the metal of the phonograph, substantially as described.

2. The combination with a phonograph having a tone arm, a goose neckat the free end of the tone arm, and a sound box at the free end of the goose neck, of a curved bracket secured to one-side of the sound box and carrying an electric lamp at its free end in position to direct the light onto the needle carried by the sound box, a source of electricity, a clamp secured on the tone arm and insulated therefrom, a pivoted switch arm on the clamp movable to either side of its pivot, said switch arm adapted when moved downwardly against the phonograph `from either side of its pivot to close the circuit to the lamp, and a spring normally holding the 'switch arm elevated in one of its positions out of contact with the metal of the phonograph, substantially as described.

In testimony' whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CLARENCE H. ROOP.
