CAROUSEL.

SPECIFICATION forming part of Letters Patent No. 573,577, dated December 22, 1896.

Application filed March 25, 1896. Serial No. 584,723. (No model.)

To all whom, it ntrty concern.-

Be it known that I, GUSTAV A. DENTZEL, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Carousels, of which the following is a specification.

My invention has reference to carousels; and it consists of certain improvements which are fully set forthin the following specification and are shown in the accompanyingdrawings, which form a part thereof.

The object of my invention is to provide a construction of carousel in which there shall be two platforms constituting two revolving decks, each of which is provided with animals or suitable supports for the riders.

In carrying out my invention I combine with a central post three sets of radial arms connected together by Vertical bolts or rods and suspended from a central pivot on the top of the post by suitable tie or suspension rods. The two lower sets of radial arms sustain platforms upon which the horses, boats, or other suitable supports for the riders are arranged, and preferably the two upper sets of radial arms are each provided at the center with an annular guide adapted to move upon a central fixed guide on the post, whereby the said upper set of radial arms and the intermediate set of radial arms are suitably guided against undue lateral vibration. The lower set of radial arms or platform-frames are suspended from the upper sets of radial arms by suitable rods and are so arranged as to leave a large central opening or space in which the operating machinery may be arranged. One set of radial arms working in connection with the central guide may be prothe supports for the riders upon the upperand lower platforms from the same shaft by means of rods extending upward and downward. The two platforms are connected by one or more stairways extending from one to the other and rotating with the said platforms and forming a portion of the carousel, so that the riders may ascend from the lower platform to the upper, or vice versa,

.In my preferred construction I make the diameter of the upper platform somewhat smaller than that of the lower platform, so as to give the upper riders a better View of the audience, and vice versa. This construction has also an advantage in cases where the building is small, since it gives more available space outside of the riders. The upper platform is preferably provided with a railing to prevent riders accidentally stepping off and becoming injured. In cases where the lower platform extends beyond the upper platform the upper radial arms also extend beyond the upper platform and long bolts or rods extend down directly from the said radial arms to the lower platform.

My invention will be better understood with reference to the accompanying drawings, in which- Figure 1 is a sectional elevation of a carousel embodying my invention. Fig. 2 is an elevation of a portion of same, and Fig. 3 is an end elevation of the cranks and eccentrics for driving the supports.

A is a central post supported in an upright position in any suitable manner.

G is an upper set of radial arms, hung by tie or supporting rods K from a plate L, pivoted on the pivot M to the post A. The inner ends of the arms G are connected to a casting H, which acts on a hub and is journaled upon a hearing I, encircling and securely fastened to the post A, the said bearing I insuring the central position of the arms and preventing lateral swinging of the said arms as an entirety. Arranged below the said arms G is a second or intermediate set of radial arms D, which are secured also to a central ring-hub E, which is likewise journaled upon a central bearing F, encircling and secured to the post A. The second set of radial arms D supports an annular platform C, upon which the riders may stand. Arranged below the second or intermediate platform C is a third or lower platform B, which may be made annular and of any suitable construction and is hung upon the vertical suspension-rods J beneath the upper platform 0.

The lower platform B is preferably of larger diameter than the platform 0, so as to extend beyond it, as shown, and in addition to its support by rods J from the upper platform 0 it has suspension-rods J extending from it directly to the upper radial arms G. The platform B essentially consists of radial arms and connecting-frames to constitute, when erected, an annular platform. It will thus be seen that there are two platforms suspended by the suspension-rods from the upper radial arms G, and, furthermore, that the platforms are sustained against lateral swinging by rotary bearings formed in connection with the upper radial arms and the upper platform. The two platforms are connected by one or more stairways b, so that the second or upper platform may be reached from the lower platform. The stairways b rotate with the platforms and are moved by the means which impart rotation to the said platforms. The frame of the platform 0 maybe provided with annular gear or circular rack N, with which meshes a pinion O, driven bya vertical shaft P, leading to any suitable driving machinery. If desired, a second similar gearing may operate upon the upper radial arms, and where the machinery is not large the power may be transmitted by either one of said driving devices alone. \Vhen the shaft P extends to the upper radial arms, the central journalbearing for the upper platform must be large enough to permit the passage of the said shaft within the journal-surface. Circular shields R B may be employed to hide the machinery arranged at the central parts of the platforms and radial arms. The lower shield R, directly about the base of the carousel-post, is stationary.

Each of the platforms C and D may be provided with supports for the riders, and these supports may be movable. In the particular illustration shown horses S are arranged upon the upperplatform and pivoted at s, and boats T are arranged upon the lower platform, pivoted at t. Secured to the underside of the arms D of the upper platform are suitable bearings, in which are journaled shafts (1, having upon their outer ends cranks h, which are connected by suitable connecting-rods n with the boats T. The shafts (Z are also provided with eccentrics h, which have straps and rods m for operating the horses S, and to properly distribute the power these eccentrics and cranks are disposed at one hundred and twenty degrees apart. It only two cranks or eccentrics are employed, then they would be disposed at one hundred and eighty degrees apart. These shafts (Z maybe termec crankshafts, since the eccentrics are in effect cranks. provided with pinions e, and these mesh with a stationary circular rack or gear E. It will now be perceived that as the platforms rotate The inner ends of the shafts d are the pinion 6 drives the shaft d, with its eccentrics and cranks 7t, and imparts motion to the supports for the riders. By arranging the driving mechanism for these supports upon the under side of the upper platform the lower platform B is permitted to be arranged close to the floor and without the necessity of forming a pit. Furthermore, by arranging said motion-transmitting devices above and in full view they may be more easily taken care of and kept in order. In place of the particular movable supports S '1 shown any others may be employed, as these are only shown to illustrate the nature of my invention.

It is evident that while I prefer the upper platform 0 to be of less diameter than the upper radial arms G or the lower platform B I do not confine myself to this construction, since it may be extended to the same diameter as these parts, as indicated in dotted lines.

\Vhile I prefer the construction shown, I do not confine myself to the minor details thereof, as they may be modified in various ways without departing from the principles of my invention.

hat I claim as new, and desire to secure by Letters Patent, is

1.
