GILBERT M. SCHERER, OF YQRK, N. Y.

PHONOGRAPH.

Application filed December 28, 1917.

To all whom it mayconcern Be it known that I, Gnimurr M. Sumner. a citizen of the United States, residing at New York, borough of Manhattan, in the county and State of New York, have invented certain new and usefullinpi-ovcrnents in Phonographs, of which the following is a full, clear, and exact description.

The invention, which constitutes the subject matter of this application, relates, in its broader aspect to several features of novelty, one of which comprises mechanism for raising and lowering a phonograph record of the disk type from the rotating disk or table upon which the record ismounted. This mechanism enables the record to be raised for the purpose of removal and also facilitates the replacement or the placing of another record thereon. Other featuresof this invention reside in the simplicity and construction of the mechanism and will appear vztrom the detailed description below, taken in connection with the accompanying drawing, in which Figure l is a frontview, partly in section, illustrating one application of my invention.

Fig. 2 is a side view of the mechanism employed in raising a record from and lowering the same upon the disk.

Fig. 3 is a top plan view of the mechanism illustrated in Fig. 2 with the reciprocating support of Fig. 4 omitted therefrom.

Fig. at isa plan view of the member for holding therecord in elevated position.

Referring to the drawings in detail, the reference numeral 10 indicates the upper portion of an ordinary phonograph cabinet of conventional construction, in connection with which there is provided the usual rotating disk 11 carried by the actuating shaft 12. The features 1 have just described are all old and well-known and I make no claim broadly thereto, except as they constitute a part of the combination which I shall now proceed to describe.

"dounted upon the rotating disk 11 is a fabric 13, provided at its center with a circular opening 14. adapted to receive the member 15 of the disk raisingmechanism. There is a part 16 below the face of the rotating disk 11, which corresponds to the part 15. These parts 15 and 16 are illustrated as being made oi solid disks; but it will be understood that this is merely the preferred form and that they may be skeletoniiied and changed in other manner with- Specification of Letters latent.

out departing from my invention. Connecting th two members if) and 16 are plurality of posts 17,'prefcrably three in number which reciprocate in a corresponding number of perforations 18 in the rotating disk 11.

It will of course be understood that the reciprocation of the members 15, 16 serves to raise the record disk from and lower the same upon the rotating disk 11. In Fig. l the record disk is in position to be lowered upon the disk 11' or to be removed from the member 15.

In conjunction with the elevating mechanism just described I employ means for actuating same so as to raise the record from the rotating disk 11 and lower same thereon. This mechanism I will now proceed to describe. p

- Upon the upper surface of the cabinet 10, I provide a securing member 19, to which is pivotally connected a double armed lever 20, the outer ends of which are provided with anti-friction members 21, which bear against the lower side of the member 16. To the plate 19 is also pivoted an operating lever 22, one end of which is provided with a handle 23 and the other end of which is pivotally connected through slot 23 to The operation of the above described mechanism as follows: The operator takes hold of the handle 23, and moves the lever 22 toward the indication Lower. This withdraws the cam face 27 from under the lateral projection 28 and enables the double armed lever 20 and the supporting mechanism 1516 to move downwardly. This lowers the record upon the disk 11. A movement of the lever in the opposite direction. that is to say, toward the indication. Raise, will elevate the record from the iOtittll'lL" disk 11. as will be understood. What I claim is: I l. in a sound reproducing; machine, rotatable record support, in combination with means art-acted to elevate a record support to vfacilitate its removal comprising a member carried by and movable axially with respect to said record support, in combination with means for effecting said axial movement of said member.

.2.'In a sound reproducing machine, a rotatable record support, in combination with means to elevate a record from said support to facilitate the removal of said record, comprising an elevating means carried by said support, and means for raising and lowermg said elevating means.

3. In a sound reproducing machine, in

.combination, a. rotatable record support,

means movable to a position above said support to disengage a record therefrom re gardless of the position of said support and means for moving said first-mentioned means to its operative position.

In a sound reproducing machine, in combination, a stationary support, a record support rotatably mounted with respect thereto, means carried by said record support for moving a record with respect there to and means mounted on said stationary support for actuating said first-mentioned means. 1

6. In a sound reproducing machine, in combination, a rotatable. record support,

means for causing a relative movement between said support and a record to facilitate removal of the latter, said means and support being mounted for relative axial' movement when said support is in any position with respect to its axis of rotation, and means for effecting a relative movement of said support and first-mentioned means.

In testimony whereof I hereunto aflix my signature. GILBERT M. SCHERER
