certain the position of the/needle point in reference to the record groove. v

A further object of'the inventionis the provision of means of the character described, which are extremely simple in construction, neat and attractive appearance,

thoroughly reliable and eflicient in its purpose' and operation, inexpensive and economical to manufacture, and which can be readily and easily repaired.

With thesev and other objects in view to be more fully setforth hereinafter, the invention consists in the novel construction, combination of elements, and arrangement of parts which will be exemplified in'the construction hereinafter described in the specification and illustrated in the accompanying drawings considered together orseparately'.

The inventive idea involved is capable of receiving a variety of'expressions, someof whichfor the purpose of illustrating the invention, are shown in the accompanying drawings.

The invention will .be firstdescribed in connection with the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views, andthen more specifically defined and indicated 1n the appended claims.

In the drawings, 7 7 Figure 1 is a sectional view of a. portion of a talking machine provided with my. in-

yention Fig. 2 is a section on the line 22 of Fig.

1; and

Fig. 3 is a detall view of a mod1ficat1on; In carrying out my inventlon I employ Specification of Letters Patent.

Application filed J'u1y 22,'1918. Serial No. 246,163.

a tone-arm 1, sound-box 2, a stationary tonearm connection or sleeve3 and motor board 4. The sleeve 3 is mounted in one corner of the motor board as is common and the tone-arm is rotatably mounted in the sleeve. The sleeve carries a guide rod 5 in disks 6 carried'on arm 7, and the tone-arm is provided with guides 8 which engage the guide rod 5.

A wire 9 leading from one of the poles of the battery is attached to one of the arms of one of the sleeve brackets. A second wire 10'leading from the other pole of the battery is attached to a contact ring or memberll on the other bracket which ring is insulated from the bracket. A similar ring or member 12 is carried'by the lowermost guide of thetone-arm and is insulated from the arm. A wire 13 is attached to the ring 12 and extends through the tone-arm to the sound box. 7

Carried by the sound box 2 and on the rear thereof surrounding the boss 14 by which the sound box is secured to the extension of the tone-arm is a removable cylindrical casing 15' of insulating material. The casing is spaced from the boss 14 by means of three'pads 16, 17 and 18 secured to the rimvofthe casing by screws 19.

The casing 15 is provided with a'radial boss 20 havingan internal screw threaded metallic lining 21 which is the socket to receive the external threaded base 22 of an incandescent lam 22 the bulb of the same projecting beyonc the boss and in proximity to the stylus 22 of the sound box.

Carried by the casing 15 and secured thereto by the pad 16 is a metal strip 23 which is in contact-with the socket 21. A

clip 24 is also secured in position by the pad againsta push button 27 fitted in an opening in the rim of the casing and projecting outside of the same. A spring 28 on which the push button is mounted is secured to the casing by the pad 18.

A dry cell battery 29 is secured on the motor board and beneath the turn-table 30. One terminal of the dry cell battery is attached to the wire 9 which as hereinbefore stated is electrically connected with the tone-arm 1 through the bracket arm 7 and sleeve 3. The other terminal of the dry cell battery is attached to the wire 10 and through the contact rings or members 11 and 12, wire 13 and strip 23 to the outside terminal of the lamp.

When the tone-arm is moved to bring the sound-box over the record disk on the turn table the push button is depressed and the spring arm 26 is brought into engagement with the boss of the soundbox, the circuit from the battery is completed and the lamp is lighted and will remain in lighted condition until the pressure is removed from the push button when the spring arm 26 and spring 28 will return the push button to its normal position, the circuit will be broken and the lamp extinguished.

In the modification shown in Fig. 3 I have shown the wire 9 extending through the tone-arm and attached to a clip which is attached to the spring 33 of the push button 27. The spring 33 is extended across the bottom of the push button and when the latter is depressed is adapted to engage a contact 3% secured to the spring contact member 25 to complete the circuit from the battery and light the lamp.

lVhile I have shown the battery 30 as secured to the top of the motor board t it will be understood that it may be placed at any point desired and the wires 9 and 10 led thereto.

I desire it to be understood that the invention is not limited to the exact details of construction herein shown and described, and that the invention may be carried out in other ways without departing from the spirit and scope of the appended claims.

Having now described my invention, what I claim and desire to secure by Letters Patent is as follows.

1. A tone-arm for talking machines, a soundbox mounted on andcarried by said tone-arm, a support of insulating material mounted on said sound-box and provided with an electric lamp socket adjacent to the stylus holder of said sound-box, contact members fixed to said support and adapted to engage the terminals of a lamp inserted in said socket, a switch mounted on said support, a source of electrical energy, electric connections between said source of electrical energy and said lamp terminal con- 2. A tone-arm for talking machines, a sound-box mounted on and carried by said tone-arm, a casing mounted on said soundbox and provided with an electric lamp socket adjacent to the stylus holder of said sound-box, contact members in said casing adapted to engage the terminals of a lamp casing for operating said switch to make and break the circuit to said lamp.

3. In a talking machine, a tone-arm of conductive material, a sound-box of conductive material mounted on and carried by said tone-arm, a casing of insulating material mounted on said sound-box and provided with an electric lamp socket adjacent to the stylus holder of said sound-box, a source of electrical energy, a contact member in said casing adapted to engage one of the terminals of an electric lamp inserted in said socket and'a wire leading from said contact member to one of the terminals of the source of electrical energy, a second contact member in said casing adapted to engage the other terminal of said lamp, a switch member in said casing in contact with said second contact member and overlying a portion of the sound-box, an electrical connection between the tone-arm and its soundbox and the other terminal of the source of electrical energy, and a push-button fixed in the casing and engagingsaid switch member and projecting through an opening in the casing for operating said switch member to cause it to engage and disengage the sound-box to make and break the circuit to said lamp.
