ROUNDABOUT.

SPECIFICATION forming part of Letters Patent NO. 476,597, dated June '7, 1892.

Application filed August 10, 1891. Serial No. 402,291. (No model.)

To (bl? whom it may concern: thereon by the stop I. Between this stop and Be it known that l, FRANK S. BALDWIN, of the collar is a ball-bearing I, which prevents Newark, in the county of Essex and State of any friction between the said parts while the 55 New Jersey, have invented certain new and post E is revolving. When it is desired to useful Improvements in Oarrousels; and I raise the said post, the gear F is revolved,

do hereby declare the following to be a full, causing the screw-threaded portion E to rise i clear, and exact description of the invention, through the correspondingly-screw-threaded such as will enable others skilled in the art to openingin the gear. This vertical movement 30 which it pertains to make and useit, reference is greatly assisted by the upward pull upon being had to the accompanying drawings, the post of the weighted lines.

which form part of this specification. Secured to the upper end of the post E is a My invention relates to an improvement in driving-plate J, which is provided with a cencarrousels; andit consists in certain novel featral socket J and the peripheral projections 65 tures of construction and in the combination K, one edge of each of which is made vertical I5 and arrangement of parts, which will be fully and the other sloping, as shown at K. Supdescribed hereinafter, and more particularly ported on this plate J is the central tilting referred to in the claims. frame or castingL, which has adownwardly- The object of my invention is to construct extendingrounded projection L, which bears 70 a carrousel which will admit of a rocking or in the socket J. Extending downward from tilting motion while being rotated and which this frame L are the vertical projections M,

The weight of the frame, purpose presently to be stated. The upper post, and other appliances being connterbalside of the frame L is provided with ribs, be-

Extending downward through this Projecting from the plate 0 is aswivel P, opening is the vertically-moving post E, the to which is connected a rope R, by means of 90 lower end of which is formed into a screw E. which the frame L and the arms N may be 40 Supported on the base A and adapted to retilted and made to revolve at any desired anvolve on the ball-bearing A is the bevel geargle from ahorizontal plane. This rope may wheel F, which is provided with a central be drawn upon at intervals to give the above screw-threaded opening,throughwhich moves result, or its outer end may be secured to a 5 vertically the screw E. This bevel-gear is post or other object and the revolving frame engaged by the beveled pinion G, secured to held at the desired angle.

the end of the shaft G, which is revolved by Near the outer ends of I the arms N are sethe engine shown in Fig. 1. cured the hangers N, to which are pivoted J ournaled in the uprights B are the pulleys the seats or other carriers S. The forward- I60 13, over which pass the weighted ropes H, the and-backward movement of these carriers is inner ends of which are secured to the collar limited by the coiled springs T,which are con- H, loosely mounted on the post E, but prenected to the opposite ends of the pivoted vented from having any vertical movement bars T on the under sides of the carriers. By

this means a continuous connection is made between the carriers, thus giving them a uniform movement or swing. The springs T are suffieiently elastic to allow the carriers to yield to the natural centrifugal force while being rotated, thus avoiding the danger of persons being thrown out.

In operation, the carriers resting upon the ground, the passengers take their seats and the wheel F is caused to revolve, while the post and frame are checked from turning. This operation causes the post and frame to rise by the action of the screw until the stop at the bottom of the post comes in contact with the bottom of the wheel F,when the post and wheel will revolve in unison. The projections on the driving-plate J on the top of the post coming in contact with those of the tilting plate L the said plate and the armsN are caused to revolve, which action can be maintained as long as desired, the rocking motion being controlled by means of the rope R, as before described. The rocking action of the frame is limited by the length of the lugs on the driving-plate,thus preventing the carriers from striking the ground while in motion.

lVhen it is desired to stop the revolution of the frame, the motion of the wheel F is arrested. The momentum of the frame causes the sloping edges of the projecting lugs on the tilting plate to come in contact with those of the drivingplate, thus causing the post to continue revolving, and by means of the screw the frame and the carriers are steadily lowered until the latter reach the ground. It is obvious that the lowering of the screw can be accelerated by causing the wheel F to revolve in the opposite direction from that of the screw. As the beveled edges engage, as above described, any oscillation which the frame might otherwise have is prevented.

Having thus described my invention, I claim 1. In a earrousel,abase, a wheel journaled thereon provided with a screw-threaded opening, means for revolving the wheel, uprights supporting a guiding-plate, a vertically-moving screw-threaded shaft, a collar loosely mounted on the shaft, weighted ropes connected at their inner ends to the collar and passing over pulleys in the said uprights, and a frame supported on the said shaft,tl1eparts being combined to operate substantially as shown and described.
