EARL W. CARLOS, OF RICHMOND, INDIANA.

ATTACHMENT FOR PHONO GRAPHS.

Specification of Letters Patent.

Application led January 8, 1917. Serial No. 141,094.

To all whom z't may concern.'

Be it known that I, EARL W. CARLOS, a citizen of the United States, residing in thc city of Richmond, in the county of Wayne and State of Indiana, have invented ya new and useful Attachment for Phonographs, of which the following is a full, clear, and comprehensive specification and exposition, the same being such as will enable others to make and use the same with exactitude.

The object of my present invention, briefly stated, is to provide an attachment for phonographs or the like whereby the stylus or reproducer point or needle may be operated to lift it from the record, or to place it gradually in operative position in connection therewith without contact of ones hand with the machine proper and to place such means in the most handy and available position for the accommodation of the operator.

In the management of disk phonographs it is necessary to raise and lower the reproducer and the reproducer-point or needle by simply grasping the goose-neck and turning it up and down, but my invention contemplates means connected to said parts whereby the goose-neck may be turned as above stated but without direct contact of ones hand therewith. thereby dispensing with soiling the polished metal parts, preventing the hand of the operator from being in the way and from causing a shadow upon the needle or reproducer-point when one is making adjustments, to permit the required movements to be made more naturally, and to make the operations more easy for the operator.

Various other objects and advantages of the invention will be suggested in the course of the following description, and that which is new will be correlated in the appended claims.

The preferred means for carrying out my invention in a practical manner is shown in the accompanying drawings. in which- Figure 1 is a perspective view of the upper portion of the mechanism of a phonograph or talking machine, showing my invention in operative position in connection therewith. Fig. 2 is a plan view of 'the'.

reproducing mechanism, of the goose-neck, a portion of the taper tone-arm, and showing an edge view of my attachment. Fig. 3 is a central longitudinal section of a portion of the tone-arm box, or cylinder, and the inner end portion of the longer portion of the goose-neck, and showing the method of attaching my device in operative position. Fig. 4 is a perspective view of my attachment alone. And Fig. 5 shows a plan View of a modified form of my attachment in operative position.

Similar indices denote like parts throughout the severalf views.

In order that the construction, the operation, and the advantages of my invention may be better understood and appreciated, I will now take up a detailed description thereof in which I will set forth the invention as fully and as comprehensively as I may.

In the drawings numeral l denotes the upper portion or top of the body or case of a phonograph or talking machine. Numeral 2 denotes the record which rests upon the usual turn-table and which is adapted to revolve horizontally in the usual manner. Numeral 3 denotes the taper tone-arm, whose larger, downturned, end extends through the top 1, and it is rotatably mounted inthe bearing 4, the latter being secured o the top l. The smaller or forward end of the tone-arm 3 terminates in and is integrally and interiorly united with the tone-arm box or cylinder 5, which latter is disposed at right-angles to the tone-arm, and itis located horizontally and parallel with relation to the record 2.

Numeral 6 denotes the goose-neck, which is bent U-shaped, the same having a long and a short end projection.

To the short end of the goose-neck 6 is attached the reproducer 7 which carries the needle point or stylus 8, which is adapted to engage the record 2, the operation of which is not material to an understanding of this invention. r

The longer end portion of 'the'goose-neck 6 lits snugly but revolubly the interior of Patented Apr. 9, 1918.

nac

the tone arm bor; 5, the end thereof being located even with the outer end of the box 5. A collar 9 is integrally' connected around on the goose neck, immediately adjoining the inner end ot the box 5, in order to prevent the extreme outer end of the goose-neck from moving endwise beyond the outer end ofthe box 5, and to provide an end bearing therefor.

Numeral l0 denotes a comparatively large tlat-headed screw. The end portion of the longer end of the goose-neck is interiorly threaded to receive the exteriorly threaded stem of the screw, with the inner Jface et the head of the screw adapted to contact with the end of the box 5, thereby retaining the longer end of the goose-neck in rotative position in the boi; 5.

All of the said parts are of common construction, and l make no claim thereto, but they are simply explained in order to make clear the application of my invention thereto.

ln the arrangement above mentioned the goose-neck, or the reproducer, is grasped by the operator and turned back, as in Fig. 2 until the reproducer rests upon the bracket ll, which latter extends trom the under side of the tone arm, thereby placing the reproducer out of commission, that is placing the stylus out ot contact with the record. Desiring then to place the stylus is contact with the record one must grasp the curved portion of the goose-neck, or the reproducer, and then turn the goose-neck in the box 5, thereby bringing the rcproducer over for- )vard to the position in which it is shown in Fig. l` thereby engaging the stylus with the record.

As will be seen, my invention contemplates operating or turning the reproducer forward and backward without the necescity ot the operator touching the goose-neck or the reproducer.

My preferred arrangement comprises a crank. which includes the lever A,having on its outer end portion a handle B, which is at right angles to the lever. rl`he inner por tion of the lever develops into a thin washerlike disk C, around the outer edge of which is an outwardly turned flange D, which flange projects in the same direction as the handle B, that is parallel with the box 5. ln the center of the disk C is the aperture l, which is adapted to receive the stem of the screw lO but without threaded engagement therewith, and the head oi the screw 10 is adapted to snugly tit within the flange D. 'l

ln order to attach my device one has only to remove the screw 10, then insert the stem et the screw through the aperture l, with the head of the screw adapted to enter within the ilange l). The screw l0 is then replaced in its former position in the end et necethe goose-neck, and at'ter being properly tightened the device will again be in operative condition.

Betere fully tightening the screw l0 the lever should be turned to position parallel with the goose-neck,'that is with the handle B approximately in alinement with the shorter end or the goose-neck, as indicated in Figs. l and 2.

lt will now be seen that the goose-neck and the reproducer may be turned forward and backward by simply grasping the handle B and then turning the lever A. as desired, thereby accomplishing the desideratum or this invention.

ln some instances l add a counterbalance weight H, which is integral with the lever A, but it projects directly opposite to said lever, and it is adapted to counterbalance the lever and the handle, weight being shown in Figs. 2 and 4.

ln some instances it may be desirable to dispense with the lever A and the handle B, and in lieu thereof to 'form a. knob X, which 'flares out trom the flange D around the screw l0 and concentric therewith, and the said knob should be provided with a knurled periphery Y, and an opening Z in the center of the outer end thereof, through which opening may be operated the screw l0,

l desire that it be understood that various changes and modifications may be made in the several details ot construction, in order to adapt the invention to various conditions, without departing rom the spirit et my invention and without sacriiicing any of the advantages thereof.

Having now itully shown and described my invention, and the best means tor its construction and adaptation to me known at this time, what l claim and desire to secure by Letters Patent ot the `United States, is-

1. ln combination with a phonograph, a crank for turning the reproducer, said crank comprising a lever portion having on its outer end portion a handle vwhich extends outwardly at right angles to the lever, the inner portion of the lever developing into a thin washer-like disk, an outwardly extending ange projecting from around the edge of said disk and concentric with a central aperture formed through the disk, said aperture being adapted to receive the stem of a screw therethrough but without threaded engagement therewith, the head of said screw being adapted to snugly t within said flange, all substantially as shown and described.
