C. K. ARMSTRONG MERRY-GO-ROUND Filed June 5, 1922 Patented Dec. 30, 1924.

UNITED STATES PATENT OFFICE.

CLAUDE K. ARMSTRONG, 0F PRINCETON, EST VIRGINIA.

MERRY- GO-ROUND.

Application filed June 3,

To all whom it may concern:

Be it known that I, CLAUDE K. ARM- STRONG, a citizen of the United States, residing at Princeton, in the county of Mercer and State of West Virginia, have invented new and useful Improvements in Merry-Go- Rounds, of which the following is a specification.

This invention relates to an amusement device which is on the order of a merry-goround, the general object of the invention being to provide means whereby a person can, by actuating the device, cause the same to travel in a circle.

Another object of the invention is to provide means whereby the device will travel in a forward direction when properly actuated but cannot be moved in a rearward direction.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 2- Figure 1 is a side view of the invention.

Figure 2 is a plan view.

Figure 3 is a section on line 3-3 of Fig ure 1.

Figure 4; is a section on line H of Figure 1.

In these views 1 indicates a support upon which. is mounted a pin 2. i A large bevel gear 3 has its hub 4 secured to the post by a set screw or the like so that the gear cannot rotate. The pin passes through the gear and a collar 5 is rotatably mounted on said pin, this collar being provided with a hole 6. A cap 7 is rotatably mounted upon the top of the pin. A beam 8 is connected with the cap and a seat supporting frame 9 is connected with the outer end of the beam. The seat is shown at 10. A double crank shaft 11 is supported in bearings which are carried by hangers 13 carried by the frame and beam, pedals 14 being secured to the cranks of said shafts. A spindle 15 is formed on the outer end of the crank shaft, said spindle passing through a bearing 16 1922. Serial No. 565,678.

formed at the outer end of the frame and this spindle carries a wheel 17. A socket 18 is formed at the inner end of the crank shaft and one end of a wooden shaft 19 is secured in said socket by a set screw or the like. The other end of the wooden shaft is suitably connected with a shaft 20 which has its inner end engaging the hole 6 in the collar. This shaft 20 has loosely mounted thereon a beveled pinion 21 which engages the gear 3. Said pinion 21 is provided with interior cam slots 21 in which are located the balls 22, these parts being so arranged that when the shaft is revolved in one direction the balls will frictionally engage the shaft and thus cause the pinion to turn with the shaft. When the shaft is revolved in the other direction, however, the balls will move to the large parts of the slots so that the pinion will not be rotated.

From the above it will be seen that a person sitting upon the seat 10 can place his feet on the pedals 14C and revolve the crank shaft. This movement of the crank shaft will be communicated to the pinion 21 through the connection shown, thus causing the pinion to ride over the gear 3 and thus cause the beam and the parts associated therewith to travel in a circle around the post. If the person should revolve the crank shaft in a reverse direction he would not move as the ball and slot arrangement would not revolve the pinion 21. The parts are supported at their outer ends by the wheel 17 which rotates freely on its spindle.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a post, a stationary gear wheel supported by the same, a pin passing through the gear wheel, collars rotatably mounted on the pin, a shaft having one end engaging a collar, a pinion carried by the shaft and engaging the gear Wheel, a beam having one end connected with the other collar, a seat supporting frame connected with the outer end of the beam, a shaft carried by said seat supporting frame cranks on the shaft,

pedals on the cranks of said shaft'nnd a shaft connecting the crank she'ftwvith the pinion carrying shaft:

'2. A device of the class describedcoih- Y prising a supporting post; a frame havingone end rotatably connected with the post yoke-shaped part, a crank shaft journaled in the; (litter end? oi the" ainkzlfilignfithe bracket; 2 second bracket en the frame for supporting the crank shaft, cranks on. the

- 21 Wheel on the crank shaft. V

lntestimony whereof I 'a flix my signature.
