RECRD-LIFTING- DEVICE FOR SOUND-REPRODUCTNG IVIACHTNES.

Application led August 2*?, i922..

To all whom t may concern Be it known that T, Earrn Cnnvnnr, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and uscful improvements in Record-Liftintg Devices for Sound-Reproducing Machines, of which the followingis a specification.

The present invention appertains to atlo tachments for or devices used in conjunction with sound reproducing machines of the disk-record type, by means of which the record may be lifted from the surface of the turntable to the more easily enable it to be grasped for removal. l

The inventionhas for its primary object the provision of simple mechanism for this purpose so constructed as to possess a wide range of adjustment whereby the degree of elevation of the dislr may be determined to suit the convenience.

Tt is further the object of this device to provide an arrangement in which the lifting operation may be accomplished even while the turntable is still in motion, or prior to the complete cessation of rotation retarded by the application of the usual brake mechanism in stopping.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed. y

Reference will now be had to the accompanying drawings forming a part of this specification, wherein:

Figure l is a vertical sectional view showing the application of my invention to a conventional form of sound reproducing machine.

Figure 2 is a lbottom plan view showing more clearly certain details of construction of my device.

Figure 3 is an enlarged sectional view taken on the line 3 3 of Figure l.

Throughout the following detailed description and on the several figures of the drawing, similar parts are referred to by like reference characters.

Referring to the drawing, l designates the top of a conventional form of sound rekproducing, machine which constitutes the Serial No. 495,988.

support for the motor, and this part will hereinafter be referred to as the motor board. Through this the usual spindle 2 projects a suitable distance above `the surface and upon said spindle the turntable 3 is removably mounted in the customary manner. I prefer that the turntable at a point surrounding its axis should be. depressed so as to receive a record lifting member or dislr 4C loosely seated about the turntable spindle and having tubular posts 5 projecting from its under surface and eX- tending through suitable openings in the said turntable. These posts are internally v threaded so as to receive adjustment screws 6 and these project downwardly from the posts into close proximity to the motor board disk 0r ring 7 which similarly to the correspondingd part l above referred to is preferably seated within the depression in the motor board, so as to lie iiush with the surface of the latter. The ring` 7 has also extending downwardly therefrom a pair of tubular projections 8, best seen in Figure 3 of the drawings, so as to receive the threaded connections 9 pivoted to a yoke member l0 which latter is in turn fixed to the end of a rocker arm or lever l1. The arm 1l is pivotally secured to the under surface of the motor board l upon a depending bracket l2 and associated with the pivot portion of the lever is a spring 13 which coacts to hold the inner end of the lever in its lowermost position as shown in Figure l in full lines. The outer extremity of the arm l1 carries a threaded stem 14 pivotally connected thereto and'this part is in turn attached to the manipulating button l5 arranged adjacent to the periphery of the turntable.

This simple mechanism constitutes the attachment which T have devised for carrying' out in a simple manner the raising' of a disk record from the surface of the turntable to enable the fingers to easily grasp the record for its displacement. ln devising this arrangement Ihave had in mind the desirability especially of providing for adjustment of the device such that the record may be raised a predetermined extent according to the desires of the operator. This adjustment may be carried out in a threefold manner: f

loo

and a lever disposed below Jhe motel' board and having adjustable connection with the lest named diei; and e button edjusubi; conneced te. seid lever through said meier beard for depressing the end of the leve-i.

lfm testimony whereof aiix my signatuie.
