AMUSEMENT APPLIANCE.

I Specification of Letters Patent. Application filed March 8, 1909, Serial No. 482,160. Renewed December 8, 1910.

Patented May 16, 1911.

Serial No. 596,372.

To aZZ whom it may concern:

Be it known that I, ROBERT C. BARBIE, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Public Amusement Appliances, of which the following is a specification.

My invention relates to a class of machines designed to receive and amuse patrons at public gatherings.

The objects of my invention are to secure a mechanical see-saw with inclined platforms having longitudinally traveling and rotatable cars thereon, all subject. to simul taneous movements and action.

Figure 1 presents a side elevation of and showing the arranged parts of the carrier and car. Fig. 2 is a perspective of my device, lacking one-half of the see-saw platform to show the general arrangement of fundamental parts in tact. Fig. 3, Sheet 2, shows a perspective view more fully illustrating the relative connection and intended operation of the various structural parts.

In constructing my device I provide a substantial foundation (1) and erect thereon a sturdy frame (2) to which I secure pillow blocks (3) to receive a rock-shaft (4), the end of which is shown in section for a purpose hereinafter mentioned. Upon this shaft I place similar inverted bearings (5) with vertical flanges (6) firmly bolted to the see-saw platform (7 which from the transverse center toward opposite ends is identical in number of parts and of like constructive form, wherefore the left end thereof is omitted to better show the general arrangement of inner mechanism.

The parts referred to are seen within a broken portion of the surface, 2'. 6., a rack gear (8) and corresponding spur gear (9) and vertical shaft (10) which carries the car (11), also a circular guide plate (12) extending under the rack, touching both sides of the recess to insure gear contact; a special casting (14:) having side arms (13) which embraces the shaft, guide plate and gear, and about which is securely entwined the endless wire cable (15) passing over the end pulleys (l6) and carrying drum (17). I next attach to the vertical shaft above the casting a circular car (11) provided with seats of usual form and a hand wheel (18) for grasping purposes, the car body being also provided with a series of swivel casters or ball bearings (19) and retaining plate (20). At the lower end of this vertical shaft is .a loose fitting cross-arm (21) shown to be (see Fig. 1) parallel with. casting 14, but intended for use transversely at right angles to said casting as in Fig. 3, said arm carrying flanged wheels (22) which run against the bottom of the platform (7) to steady the shaft and car, being retained by collar (23).

The driving mechanism consists of a motor (M) connecting with a counter shaft (25) with straight and cross belts (26) (27) driving a second shaft (28) which in turn connects by gearing (29) to a third shaft (30) carrying the winding drum 17). I now construct a stationary platform (31) as means of access to and from the cars, this completes a single operating mechanism. 1* owever, in practice it is better to extend the shaft (41) in connection with a third frame like unto (2) to obtain a double construction in order that one machine may operate while the other is letting patrons off and on and thus facilitate traflic.

The heavy cross marks indicate relative positions of cars, for instance, when the left-hand car (not shown) is at (A) car (11) will rest at (B).

The operation of my appliance will be understood to be as follows, the arrows indicating the directions of various movementsz-Having applied power to shaft (25), it will cause the drum (17) to wind the cable to the left and draw the platform (7) down in direction of arrow simultaneously pulling the connected cars to the right; during such movement the gears (10) rotated by racks (9) will revolve the car body to the left. Having reached the maximum fall, motion is reversed by shifting belts (27) this will reverse the motion of the drum which will then draw the cable to the right raising the platform and reversing the motion of the car in a manner like unto an ordinary see-saw, and thus establish alternate vertical oscillations, inclined sliding and reverse circular movements which simultaneously combine to produce pleasing, sen sational and exhilarating effects upon mind and body.

Having thus described my invention, what I claim as new is An amusement appliance comprising a support, a horizontal rock-shaft on the support, a platform secured between its ends on the rock shaft and having a slot extending longitudinally through its middle, a toothed rack in the slot and extending longitudinally of the platform, a vertical shaft in the slot projecting above and below the platform, a car secured to the shaft and resting on the platform, a pinion fast on the shaft engaging the teeth of the rack, guide Wheels for the shaft, guide pulleys on the ends of the platform, a reversible actuating drum, and a cable connected With the vertical shaft and passing over the guide pulleys to the actuating drum With power means as and for the purpose herein set forth.

Signed in the city and county of Phila- 1 delphia, State of Pennsylvania this 2d day of March 1909.

ROBERT C. BARBIE. l
