'Thisinvention relates to improvements in retary stands. In cabinets cupboards and the-like it is frequently diificult to reach smaller articles placed toward the back thereof, and it is therefore an object of this invention to provide a rotary stand having one or more shelves thereon which turn with it so that ready access may be had to any of the articles placed on one of the shelves.

Another object of the invention is to provide a rotary stand which is adjustable as to height so that one of my stands may be installed in either of several cabinets or cupboards wherein the vertical distance between the top and bottom walls differs to some extent.

A further object of the invention is to provide a rotary stand which may either be rotatably supported upon the bottom wall of a cabinet or cupboard in which it is installed, or upon a member secured to the underside of the said bottom wall so that a shelf on the stand is rotatable in an opening formed in the bottom wall and is in horizontal alignment with the latter.

Havin thus briefl stated some of the objects and advantages of the invention I will now proceed to describe it with the aid of the accompanying drawing, in which:

Figure 1 is a side elevation showing the rotary stand mounted between the top and bottom walls of a cabinet or cupboard.

Figure 2 is an enlarged view thereof, partly in section.

Figures 3, 4 and 5 are sections on the lines 33, 1-4 and 5-5 respectively of Figure 2, and

Figure 6 shows a slightly modification.

Referring to the drawing, l designates a sl in dle having an upper portion 2 of smaller diameter connected to a lower portion 4 of larger diameter by a downwardly and outwardly tapered collar 3, and the lower extremity of the H lower portion 4 terminates in a second downwardly and outwardly tapered collar 5 Extending downwardly from the latter is a projection 6, or Go. The spindle I is bored at I from its upper extremity for a portion of its length to rnceive a helical spring 8, and mounted also in the bore 1 is a cap 9 the upper end of which is closed and rests on the top of the spring 8. Formed integral with the closed upper end of the cap 9 is a cone ID the lower, larger portion of which is of somewhat smaller diameter than that of the cap, thereby forming an annular shoulder ll around the top of the latter. Suitably secured around the outer circumference of the spindle l is an annular retainer i2 having an in- "ternal-fiange 13 around its upper extremity to engage the shoulder H and limit the upward movement of the cap.

Resting against the underside of the upper wall A of the cabinet or cupboard B is a suitable pad I 4 against the lower face of which a cup I5 is arranged. The underside of the latter is centrally and vertically threaded for the passage of a screw [6 therethrough which is held immovable in the cup by a lock nut ll, Formed in the underside of the screw is countersink is to receive the upper extremity of the cone Iii. Thus through resilience of the spring 8 and adjustment of the screw IE the distance between the top of the spindle l and the top. of the cup may be varied to a marked extent so that the height of my stand may be varied to suit the distance between the upper and lower walls A and C of the cabinet in which the device is to be installed.

Mounted on the tapered collar 3 is an annular supporting member 2|] the bore of which is tapered to correspond with that of the collar. Projecting around the upper portion of the member 20 and integral therewith is a flange 2! against the underside of which a shelf 22 is held by a nut 23 in threaded engagement with the outer circumference of the lower portion of the said member. A second shelf 2 is provided with a tapered bore 25 to correspond with and engage the tapered periphery of the collar 5 on which it rests. Thus both the shelves 22 and TM are so supported on their respective collars on the spindle I that they rotate with the latter.

In the arrangement shown in Figures 1 to 5 inclusive the projection 6 extending from and beneath the lower collar 5 is of uniform diameter throughout its length. In this instance a circular opening C is formed through the lower wall C to receive the shelf 24, and secured to the underside of the said lower wall is a plate 2% having an annular recess 2'! formed in its upper face. Supported in the recess 2'! by a suit able retainer 28 is a ball bearing 29 in which the projection 6 is rotatably supported. Thus the lower shelf 24 is positioned in the same horizontal plane as the lower wall C.

However if it is not desired to cut the said lower wall C I then employ the modified arrangement shown in Figure 6. In that case a flat bearing plate 3!] is suitably secured on the lower wall C and the projection 6a consists of a pin driven into the underside of the lower flange 5 coaxially with the latter; the underside of this pin is downwardly tapered to engage a counter sink 32 formed in the upper face of the plate 30.

While in the foregoing the preferred embodiments of the invention have been described and shown it is understood that alterations and modifications may be made thereto provided the said alterations and modifications fall within the scope of the appended claim.

What I claim is:

A rotary stand including a thrust bearing adapted to be supported by a bottom horizontal wall, a vertical spindle having its lower extremity rotatably mounted in said bearing, a cup adapted to bear against the underside of a top horizontal wall, the underside of the cup having a vertical threaded opening therethrough, a screw extending through said threaded opening and projecting beneath the latter, the upper extremity of the spindle being tubular, a cone projecting upwardl from the tubular extremity and supporting the lower extremity of the screw, and a helical spring in the tubular extremity of the spindle beneath the cone urging the latter upwardly and retaining it in contact with the screw as the latter is rotated to move the cup into engagement with the top horizontal wall and tending to hold the cup in engagement with said latter Wall, and shelves fixed around the spindle intermediately of its height for rotation therewith.
