FERDINAND STRAUSS, OF NEW YORK, N. Y.

' DISPIIJAY nnvrcn.

Application filed. October 7, 1922. Serial No. 592,931.

To aZZ whom it may concern.

Be it known that I, FERDINAND S'riiAUss, a citizen of the United States of America, re siding at New York city, county and State of New York, have invented certain new and useful Improvements in Display Devices, of which the following is a specification.

This invention relates to display devices and in particular to a turntable upon which are exhibited various articles to be sold, such as toys and the like.

An object of the invention is to provide a display table which will be caused to have various rates of turning movement which will be governed automatically. A. further object is to provide a means whereby the table may be rotated in reverse directions, such change of direction being also afforded automatically.

Another object of the invention is the provision of sufficient mechanism whereby the movements of the table will continue for a comparatively extended period. Other objects and advantages will be brought out as the specification progresses, reference being had also to the accompanying drawing, in which Fig. 1 is a sectional elevational view of my improved table showing the operating mechanism which propels the turntable;

Fig. 2 is a top plan sectional view of the mechanism as seen in Fig. 1, the section be ing taken on line 22, of Fig. 1.

Referring to the drawings in detail, C denotes a portion of a cabinet in which is housed the driving mechanism, a driven shaft 10 extending therefrom upwardly through the'top of said cabinet to support at its upper end a turntable 11 upon which is mounted the articles to be displayed.

The mechanism is mounted in a frame 12 and consists of two springs disposed within the spring chambers 13 and 14:, the chambers being mounted upon the shaft 15 suitably held in the frame. The upper chamber 13 has formed on its lower edge an annular gear 16 which meshes with a pinion l7 suitably secured on the end of a horizontal shaft 18 which is journaled in the bracket 19 and extends to the exterior of the cabinet. The end ofthe shaft may be squared to receive a suitable winding handle, through the medium of which the springs are wound.

The lower spring chamber 14 has formed 011 its lower edge gear teeth 20 which mesh with a pinion 21 carried by a shaft 22 upon which is also carried a larger gear 23 which in turn meshes with another pinion 24 carried by a stub shaft 25 which is retained in place by the nut 26 engaging the threaded end thereof. This stub shaft also carries adjacent the pinion 24 and thereabove, a circular disk 27, and below the pinion a gear wheel 28. This latter gear wheel meshes with a pinion 29 carried by a worm shaft 30 upon which is fixed a worm gear 31. The gear and worm wheel 32 mesh, the latter being disposed on a horizontal shaft 33 which is provided with an enlarged slotted end into which there is fitted a blade 34, the latter being placed exteriorly of the frame and acting in the usual manner as a governor for the mechanism.

Fixed upon the table carrying shaft 10 is a pinion 35 in position to be driven by a gear wheel 36 which is carried by a vertical shaft 37 The disk 27 and the gear 36 are ,connected by an eccentric rod 38, which is held thereto by suitable screws. The end of the eccentric rod is fixed to the gear 36 near the periphery thereof. The other end may be fixed at any one of a number of openings 39, which are different distances from the center of the disk and which serve to vary the throw of the eccentric rod 38.

The movement of the eccentric causes what is the most important feature of the invention, namely, the rotation of the turntable at varying speeds and in either direction. \Vhen the disk makes one revolution, it may, depending upon where the eccentric rod is fixed, cause the gear wheel 36 to move slowly, then quickly, then reverse entirely and in fact have a multiplicity of movements which affect the turntable in a proportionately greater degree because the pinion 35, which meshes with gear 36, makes many revolutions to one of said gear.

The monotony of having the table move at a constant speed and in the same direction is therefore eliminated and the articles to be sold are displayed together with an attention attracting display table. The mechanism described will provide a coin paratively prolonged period of operation of the turntable.

What I desire to secure by Letters Patent is 1. In a display device comprising a turntable, a train of gears and means for operating said train of gears to rotate said turntable alternately in opposite directions, an eccentric link connectionbetween tyvo gears,

and 'Ineansfor permitting an adjustment of said link connect-ion for automatically allow ing a variation of the speed of rotation. oi 5 said turntable in either direction.

2. In a display device comprising, a turntable, a train of gears and a spring motor for operating said gears-to rotate said turntable alternately in opposite directions, a link thereby allowing an automatic regulation of the speed of rotation of the turntable in either direction.

In testimony whereof I hereunto atlix my signature.

FERDINAND STRAUSS.
