Abstract
Abstract A seat secured to one end of a horizontal beam whose opposite end is secured to a vertical support column for horizontal rotation of the seat in a circular path, with propelling means in the form of a ringlike track, arranged beneath the seat, and having a curved upper surface forming peaks and valleys and interconnecting ramp portions. A propulsion wheel rides upon the track and is rotatably connected to the lower end of a lever connected between its ends to a pivot on the seat, so that rearward pulls upon the upper end of the lever, while the wheel is upon a descending ramp portion, causes a reaction to propel the seat forwardly.

In a rider propelled merry-go-round having a vertical support column with a radially and horizontally outwardly extending beam having its inner end secured to the column, and a seating means, having a forward end, secured to the outer free end of the beam, and with the beam and seating means together being rotatable, in a horizontal plane about the axis of the column, and means for propelling said seating means comprising: a circular ring arranged horizontally and coaxial with the support column beneath the seating means, with the upper edge of the ring forming a circular track surface which gradually curves upwardly and downwardly to form a number of peaks and valleys interconnected by ascending and descending ramp portions; a propelling lever arranged in a vertical plane and secured to the seating means by a horizontal pivot and having an upper lever portion extending upwardly above the pivot and having an upper, free, handgrasp end portion arranged forwardly of and for handgrasping by a rider, and a lower lever portion extending downwardly and rearwardly of the pivot and having a wheel rotatably mounted upon the lower end of the lower lever portion, the wheel being arranged to roll upon said track surface below but at all times rearwardly of said pivot; with said pivot moving at all times in a horiZontal, circular path with the seating means, wherein hand pulling the upper lever handgrasp portion rearwardly, that is, towards the rider, while the wheel is on a descending ramp portion causes a forwardly directed reaction therefrom to propel the seating means forwardly, with the wheel otherwise idling as it rolls along the remainder of the track surface.
