REVOLUBLE SHOW-CA8 E.

SPECIFICATION forming part of Letters Patent No. 726,900, dated May 5, 1903. 7

Application filed January 9,1903. Serial No. 138,384. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES GANTERT, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Revoluble Show- Cases, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to revoluble showcases; and it is my object to provide a showcase of this type with a series of hinged doors or closures having spring-latches which are automatically operated by revolving the case to unlock each door as it arrives at a given point-as, for example, when the several doors reach a point facing the operator behind the counter they become unlocked.

I have shown my invention as applied to an upright revolving case for exhibiting plug tobacco having a division in the middle; but I do not confine myself to this type of revolving show-case, as it is evident my invention is adapted to other types of revolving cases.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of the revolving show-case mounted upon a pedestal. Fig. 2 is a central vertical section of said case and its pedestal, showing the locking mechanism and means for operating the same. Fig. 3 is a top plan view of the top of the pedestal, and Fig. -lis a bottom plan view of the show-case.

Referring more particularly to the drawings, A denotes an upright rcvoluble showcase, and ll a pedestal upon which said case is mounted. The case proper is composed of of a top piece A, bottom piece A", and partition A framed in with four uprights or risers A, forming an octagonal frame with an upper and lower compartment, which are separatcdby the partition A.

A denotes eight glass doors the frames .of which are hinged to the risers A and provided with catches (a The bottom A is pro vided with a central bearing a, whi'cli'rcgisters with a journal projecting from the top of the pedestal. It is also provided with four friction-rollers a, which ride upon a track, hereinafter mentioned. C denotes four arms pivoted midwayof their-length to bearings c,

friction-wheels secured at one end of said arms 0, the other ends of said arms being pivoted to four vertical plungers D, which secured to said bottom piece. 0 denotes four bearing a in the-botton'l of the show-case in which it revolves.

B denotes a circular track fastened to the top of the pedestal on which the frictiopwheels a bear.

B denotes a shoe or short raised track with beveled ends mountfed to the top of the podestal outside of the circular track in the path of the friction-wheels c. Said wheels c in their normal position strike the track BF and ride over it, as hereinafter mentioned.

The plungers D are preferably. divided.

about midway of their length and their ends united by turnbuckles D. Theupper ends of each plunger are threaded andprovided with threaded collars, which are thereby adv j ustable vertically.

E denotes metal plates fastened to the risers about midway of their length, provided with pivoted latches e, which engage catches-a.

Said catches have projecting ends e, which are perforated to admit the passage of the upper ends of the plungers D. I

e denotes coiled springs securedto plates E and fastened to projecting ends of said latches. The tension of said springs is such that the plunger-rods are drawn up to their normal place, andin this position of the plnn: gers the glass doors of the revolving case are held locked. This position of the plungerrods also holds upward the endof. the arms 0, to which itis attached, and thus holds down the opposite ends of saidarms carrying the friction-wheels 0, so that as the showcase is revolved said wheels will contactwith and ride over the shoe B The show-case being: mounted upon the pedestal and the several parts being adjusted as described, they will operate as follows to unlock each one of the glass doors as they arrive in turn oppositethe point desired. The pedestal is arranged with the shoe- B at the iii point desired where the doors are to be unlocked. As the case is revolved the nearest end will thusbe raised from engagement with the catch a. Thus each door in turn will be automatically unlocked as it reaches the position mentioned.

Having thus described my invention, what I claim, and desire to secure by Letters Pat-' cut, is

1. A rotary showcase having a series of hinged doors arranged with spring-latches a series of plungers connected to said latches tation to unlock said latches at and means for operating said plungers in roa given point at each revolution of said case.

2. In a rotary show-case the combination ofv thehinged doors, latches for said doors, plunger-rods connected to said latches, springs for actuating said plunger-rods in one direction, pivoted arms connected to said plunger-rods for actuating the same in the opposite direction, and means for actuating said arms in rotation at a given point to unlock sai'd latches. 3. In a revolving show-case the combination of the hinged doors, the latches, the plunger-rods, the springs attached to said latches and plunger-rods, the pivoted arms attached to the bottom of the show-case having one end connected to the plunger-rods and their free ends projecting below the case and a stationary shoe arranged exterior of the showcase and in the path of the free ends of said pivoted arms and adapted to rock the arms in rotation at a given point.

In testimony whereof I affix my signatn re in presence of two witnesses.
