To all whom it may concern:

Be it known that I, GEORGE E. Bnnnnonnn, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Lighting Attachlight.

Another object is to provide an improved lightin attachment W 'ch is normally inactive ut which is adapted to be operated in the act of manipulation of the sound reproducing machine in changing records or needles. a y

Another object is to provide a lighting attachment which may be supported indeendently of the sound box of the machine ut which will serve to efl'ectively illuminate the needle carried thereby and that portion of the record beneath the sound box.

Other objects and advantages of the invention will hereinafter appear.

The accompanying drawings illustrate embodiments of the invention. The views of said drawings are as follows:

Figure 1 is a perspective view showing the lighting attachment applied to a Victrola.

Fig. 2 is a side elevation of the lighting attachment.

Fig. 3 is a top plan view thereof.-

Fig. 4 is a cross section view.

Fig.5 is an end elevation.

The sound reproducing machine to which the invention is applied will first be briefly described.

It comprises a frame or box 1 containing. apparatus for supporting and rotatlng the fiat disk record 2. Bearing upon the disk swin a bearing 4 carried by the arm A who Is supporte by the frame 1.

The lightm attachment is constructed so that 1t may e quickly applied to and be supported by the bearing 4: of the arm 4.

The attachment comprises in general a caslng 6 arranged to fit over the end of the bearmgft, a cap 7 mounted on one end of the casing 6 and insulated therefrom, an electric lamp 8 carried by the cap 7 and a TWltCh 9 for completing the circuit to the amp.

The casing 6 is preferably cylindrical in shape. It has an opening 10 in one side thereof and communicating with said opening are slots 11 which form spring fingers 12 in the casing adapted to 'p the circular end of the bearing 4'. This construction permlts the casing to be readily slip ed over the end of the bearing 4', the resil enc of the casing and the fingers 12 serving to old the lighting attachment in place; A head 13 is formed in the casing for preventing it being moved beyond a certain position on the bearing 4:- This bead properly positions the casing on the bearing and insures that the ray of light from the attacent is properly directed.

The cap 7 fits over one end of the casing 6 and is thoroughly insulated therefrom by an insulating cap 14 which surrounds the end type. As shown, it comprises a small electric bulb carried in a hemispherical holder and reflector 16 which is arranged to be received and held in the end of the cylindrical projection 15 of cap 7. One terminal of the lamp is connected through the holder 16 to the projection 15 and the cap 7, the other terminal being connected to a conductor 17 which is led out through a conduit 18, said conduit forming a stem or handle for the attachment and also serving as a conductor from the casing 6 to the hindand attached to the cap 7. The spring extends over the casing 6 and is provided on its end with a small contact point 20. Under the influence of the pressure of the hand of an operator the spring is forced into contact with the casing 6 and a circuit to the light com leted as noted above.

T e attachment is constructed so that when it is applied to the bearing 4' the switch 9 is at the top of the attachment as shown in Fig. 1. Accordingly when the operator grasps the arm 5 and the needle holding apparatus to change the needle or to move it on the record he automatically touches the switch 9 and closes a circuit to the light 8 so that a beam of light is thrown on the record where the needle is applied. The location of. the switch is such that it will invariably be closed by anyone who manipulates the machine without any conscious efi'ort on his part.

The attachment is supplied with electrical energy from any suitable source. In the present instance a battery 21 is shown which maybe located in any part of the machine. The battery is connected to the attachment by suitable conductors 22 which are brought up at the rear of the machine.

The shape andsize of the attachment is such that when it is placed in position it is scarcely noticeable and to any ordinary observer appears to be a part of the machine. The casing 6 and the cap 7 correspond in shape to the bearing 4 and appear to be merely an extension of the arm 5. The conduit 18 extends along the arm 4 and is not noticeable. The conductors 22 at the rear of the machine are small and in such a position that they are not readily observed.

It will thus be seen that a simple attachment has been provided which may be readily applied to existing machines. When applied it does not detract from the appearance of the machine. Further, it does not add to the weight of the sound box for the attachment is supported entirely by the arm 4. A beam of light is thrown-on the needle when the needle carrying means is manipulated because ordinary manipulation of the needle carrying means will almost invariably result in a closing of the switch. Very little energy is re uired to operate the lamp as the circuit to t e lamp is normally open and ener is consumed only when the light is neede The switch for closing the circuit may be closed without special effort on the part of the operator. The attachment is simple, inexpensive, economical and eflicient.

It is to be understood that the structure shown is for purposes of illustration only and. that other structures may be devised which come within the spirit and scope of the appended claims.

What I claim and desire to secure by United States Letters Patent is 1. The combination with a sound reproducing machine having an arm, a sound box pivotally connected thereto, and a needle assoc'iated with the sound box whose downward pressure is not increased by said arm of an electric lighting attachment supported wholly by said arm to illuminate the record and a switch carried by said attachment-for completing an electric circuit to the attachment. I

2. The combination with a sound reproducing machine having an arm to which is pivoted a U-shaped arm carrying a needle whose downward-pressure is not increased by said first named arm, of an electric lighting attachment supported wholly by said first named arm and arranged to throw a beam of light on the record, said attachment having a switch thereon adapted to be operated to energize the light in the act of manipulating said. U-shaped arm.

3. The combination with a sound reproducing machine having an arm to which is pivoted a U-shaped arm carrying a needle, of an electric lighting attachment applied to said first named arm and arranged to throw a beam of light on the needle, said attachment having a conduit projecting along the main arm of the machine and being also rovided with a switch on top of the same or completing an electric circuit to the attachment.

4:. An attachment for sound reproducing machines, comprising a casing, a cap attached to one end of said casing and insulated therefrom, aid cap carrying an electric lam and being connected to one terminal 0 said lamp, the other terminal of said lamp bein connected by a conductor to one terminal 0 an electric circuit and means for completing a circuit from said cap to said casing, said casin being connected to the opposite terminal 0 an electric circuit.

5. An attachment for sound reproducing machines, comprising a casing, said casing having a hollow conduit attached thereto and connected to one terminal of an electric circuit, a cap carried by said casing and insulated therefrom, said cap having an electric lamp mounted therein, one terminal of the lampbeing connected to the ca and the other to an electric conductor w ich is led out through said conduit, and means for completing a circuit from said cap to said casing to complete the circuit of said lamp.

6. The combination with a sound reproducing machine having an arm with a bearing disposed at right angles thereto and a U-shaped arm pivoted in said bearing and carrying a sound box and needle, of an electric lighting attachment comprising a tubular casing telescoped over said bearing and constituting, in elfect, a longitudinal extension thereof, and an electric lamp associated with said casing for throwing a beam of light on the record.

7. The combination with a sound reproducing machine having an arm, a sound box pivotally connected thereto and a needle associated with the sound box whose downward pressure is not increased by said arm of an electric lighting attachment supported wholly by said arm and arranged to throw a beam of light on the record, said attachment having a switch thereon adapted to be operated to energize the light in the act of manipulating the sound box.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
