WIL FRED ATKINSON, OF PHILLIPSBUBG, NEW JERSEY. I I

To all whom it may concern:

Be it known that I, WILFRED A. ATKIN- soN, a citizen of the United States, residing atPhilliips'burg, in the county of Warren and State 0 New Jersey, have invented new and useful Improvements in Phonograph Attachments, of which the following is a specification. v

The invention relates to phonograph attachments, and more particularly to the class of automatic lighting attachments for phonograph or the like cabinets.

The primary object of the invention is the provision of an attachment of this character wherein an electric light is placed within the lid of a phonograph or the like cabinet so that it will become illuminated on the raising of the lid for supplying light to permit the operator of the phonograph machine to properly place the stylus upon the record and thereby avoid scratching of said record by misplacing the stylus after the starting of the phonograph.

Another object of the invention is the provislon of an attachment of this character wherein the lid automatically controls the electric light so that it can be illuminated on the raising of the lid of the cabinet of a phonograph, and when the lid is closed the electric circuit is automatically opened for extinguishing the light.

- features, of construction, combination ofele-1 A further object of the invention is the provision of an attachment of this character wherein the electric circuit for the light is bothautomatically and hand controlled.

A still further object of the invention is the provision of an attachment of this character which is extremely simple in construction, thoroughly reliable and efiicient in its purpose, readily and easily applied within the cabinet of aphonograph and inexpensive in manufacture and installation.

- Other objects will be in part obvious and in parthereinafter set forth.

The inventiorf accordingly consists in the ments and arrangement of vparts which will be exemp ified in the construction hereinafter desc ibd, and the scope of thel'appli- 56 the. attachment constructed in accordance cation of which will'be indicated gin the appended claim. v

In the accompanying drawings: V Fi re 1 is a erspective view of a phonocabinet s owlng the lid raised, with with the invention applied; 7

Patented Aug. 7, 1911'.

Fig. 2 is a fragmentary vertical sectional v1ew through the automatic and hand controlled current switch;

Fig. 3 is a diagrammatic plan view show- 60 111% the electric circuit and light.

imilar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawin designates a phonograph ca inet which is of the ordinary well known construction having the hinged'lid or top B which, when raised, permits access to be had to the phonograph instrument for the thereof, and within the body A is arranged the light attachment hereinafter fully described. The light attachment comprises an electric bulb socket 5 which is fixed in any suitable manner interiorly of the lid or top B on the inner face thereof, and within this socket is mounted the ordinary incandescent globe 6,*the same being lighted by means of electrical connections including the

current wires

7 and 8 respectively, battery 9 and circuit closer, the wires being extended to the back of the cabinet so as to be out of the way and not interfere with the operation of the phonograph, while the battery 9 is 10- cated within the body A of the cabinet, and the cut-off is arranged in one wall of said body to be automatically operated by the lid B in a manner presently described.

The cut-off comprises a hollow barrel 10 which is set in the wall of the body A of I the cabinet so that its attaching plate 11 will be flush with the upper edge of said wall.. Within the barrel 10 is a Shuttl plunger '12 having a bridging shoulder 13,

against which works a -coiled expansion spring let surrounding the plunger 12 and supported within the barrel 10, ,the spring being designed to project the plunger 12 without the barrel through the plate 11 into Ice T the path of movement of the lid B when being closed.

Arranged interiorly of the barrel 10 at opposite side? thereof and insulated from in detail, A 65 playing 7 0 the same are contacts 15 which have connected therewith branches"or stretclics of the current wire 8, and these contacts 15 are disposed in the path of movement of the bridging contact shoulder 13 so that when engaged therewith the electric circuit will be closed to the lam for illuminating the same; The lid B, w on closed, acts upon the 1'2, forcing the same inwardly the circuit for the. extinguishing of the lamp 6 interiorly of the lid.

The-plate 11 is suitably countersunk to receive a hand slide 16 which is adapted to i by opening the circuit. The plate 16 is operbe movedover the plunger -12 for holding the same against the resistance of the spring 14, whereby the shoulder 13 will be out of engagement with the contacts 15 and thereated by hand and in this manner the circuit can be opened and closed, as will be obvious. p

It is of course understood that when the lid is in closed position the lainp 6 is extinguished. The plate 16 is flush with the upper surface of the plate 11 and slides in the countersink in the latter.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the herein described attachment will be readily apparent and, therefore, a more extended explanation has been omitted. Having thus described my" invention, I claim:

A cut out for an electric circuit comprising a hollow barrel adapted to be mounted within the wall of an inclosure and having a plate flush with the mouth thereof, a pair of-contacts arranged within the barrel and insulated therefrom and adapted to have connection with the wires of the circuit, a socket provided in the bottom of the barrel, a plunger slidably mounted within the barrel, one end of said plunger being mounted in the socket and having its opposite end slidably engaging an aperture in the above mentioned plate, a bridge piece located upon said plunger between the ends thereof for engagement with the contacts to close the circuits, a spring surrounding said plunger and interposed between the bridge piece and the bottom of the barrel to force the said plunger without the plate into the path of a movable part of the inclosure, whereby, on bringing the movable part into contact with the other edge of the inclosure the plunger will be displaced to open the circuit, said plunger being formed with a tapered end, said plate being formed with a counter seat and a slide operating in said counter seat and engaging with the beveled edge of the plunger to act thereon upon movement of the slide in one direction to receive the plunger.

In testimony whereof I afiix my signature.

WILFRED 'A. ATKINSON.
