Specification of Letters Patent.

Patented May 9, 1911.

Application filed September 9, 1910. Serial No. 581,251.

To all whom it may comm:

Be it'known that 1; PAUL RAPOPORT, a subject of the Czar of Russia, and resident of New York city, borough of .Manhattan, in the county of New Yorkand State of New York, have invented certain new and useful Improvements in Display-Cases, of which the following is a specification.

An object of my invention is to provide improved means to rotatively support a display stand and to enable its ready placing in position and removal.

My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, illustrating a side elevation, partly broken away, of a display case embodying my improvements.

My improvements may be applied in any suitable display case, such as a case having a base 1, walls 2 and a top 3 of glass suitably secured together, and a rear wall 4, which may be of wood provided with a door to permit access to the interior. The case is shown provided with a shelf 5, supported by posts 6. Shelf 5 is shown provided with a bearing 7 receiving anti-friction balls 8, against which a bearing 9 bears. A' shield 9 carried by shaft '10 is shown surrounding bearings 7 and 9. The bearing 9 is provided on a vertical shaft 10, which is shown provided with trays 11 to support the goods to be displayed, the upper end of shaft 10 being guided by a post 12 shown carried by the top glass 3 and removably held by screw 12 The shelf 5 and bearings 8, 9 thus su port shaft 10 and the goods to be displaye and relieve the motor driving shaft from the weight of such parts. I have shown shaft 10 provided with the hollow guide 10", contain- 7 ing a spring 13 bearing against a rod 14 sliding within the bore of guide 10, and adapted to enter a socket in post 12, a handle or screw 15 passing from rod 14 through a slot 10 in ide 10. By this means, the rod 14 may be epressed to enable it to be connected with and disconnected from post 12, spring 13 normally retaining rod 14 pressed upwardly, wherebyshaft 10 is rotatively supported.

Shaft 10 is to be rotated by shaft 20 of the 7 motor, which shaft passes through the opening 5 of shelf-4. The motor has driving spring 22 to rotate shaft 20 by suitable gear- ..ing 25, 20 29, 30, and a regulating fan 31,

the spring being wound by a lever 40 pivoted in the motor frame 23 and operating in usual manner.

My invention is not limited to the details of construction set forth, as the same may be varied, within the scope of the appended claims, without departing from the spirit thereof.

In this application I do not cl im the construction of the motor set forth.

Having I claim is -1. The combination of a motor having a power transmitting shaft, a shelf above the motor, a bearing on the shelf concentric with the motor shaft, a shaft alined with and above the first named shaft and having a bearing supported by the first named bearing independent of the first named shaft, means to guide the upper end of thefirst named shaft, and means to detachably and rota-" tively connect said shafts.

2. The combination of a motor having a power transmitting shaft, a bearing surrounding said shaft, a display shaft having now described my invention what a bearing to coact with the first named bearing, means to detachably and rotatively connect said shafts, a case having a shaft guiding post, the display shaft being provided with a sleeve, a rod in said sleeve adapted to coact with said post, a spring to normally hold said rod in engagement with said post, and means to slide said rod.

3. The combination of a motor having a power transmitting shaft, a bearing adjacent to and above the motor, the shaft, a shaft alined with the first named shaft and having abearing coacting with and su ported by the first named bearing, means or detachably and rotatively connecting said shafts, and means for guiding the upper end of the second named shaft. I 7

Signed at New York city, in-the county of New York, and State of New York,-this 23rd day of August, A. D. .1910.

PAUL BAPOPORT.
