Application November 20, 1944, Serial'No. 564212 9 Claims. (01. 2 112-33) This invention relates .to apparatus for con.- verting vertical reciprocal motion .into rotary motion applicable to rotating platforms such as are used .in merry-go-groun'ds and other rotatingplatforms, and wherein the apparatus is carried by 'and rotatedwith the platform.

A further object of the invention 'is the 'pro vision of an 'apparatus'of this character which may be operated successfully by'a singleoperator at one end. of the apparatus or an operator at both-ends thereof.

A still further object is the provision of an apparatus-of this character which is of simple, efficient, durable and inexpensive construction.

The foregoing and other objects will appear as .my invention is .more fully hereinafter :de-. scribed 'in the following specification illustrated, in the accompanying draw-ings, and finally pointed out in the appended claims.

'In the-drawings:

Figure -1 is a plan vieW'ofinyinventionapplied to a merry-goround, with'parts-brokenaway for convenience of illustration.

Figure 5 is asectional view, taken0.nl-1ine'5-'5 ofFigure 1.

Figure Bis-a fragmentary sectional view, taken on .the .line '6-6 of Figure 1, illustrating the supporting and driving assembly.

Referring now more particularly to the drawings:

The apparatus is mounted. upon a stationary supporting column I, which may be embedded 'in concrete 2, or fixed permanently-to the ground surface in any other suitable 'fashion. -A base plate or bracket 3 is rotatably mounted to the column Ion a suitable bearing 4, providing free rotation about the post.

Upright frames 5 are fixedly secured to the bracket 3 by any suitable fastening means, as Cross or horizontal frames or beams 1 are fixedly secured to the lower end 'of-the frames 5 by means of bolts 8. The frames 5 are held in spaced relation by a cross frame 9 which provides an upper bearing l ll a'bout the vertical column I. The frames Send the cross frames .1 are rigidly secured together andrrotated about the vertical supporting column on their bearings 4 and I0.

Twopairsof walking beams l l and IZ'are pivotally mounted toithe frames 5 by a cross shaft [3 and stub shafts M respectively. Pivotally mounted on either end of the walking beams are vertical frames l5 and I6 by means of cross shafts Handiit. The assembly of the walking beams and th'e vertical frames constitutes a parallelogram arrangement. The frames [5 and Hiremaining ina :vertical position at all times asthe walking ibeams H and [2 are pivoted about the shaft +3. A-frames comprising arms 19 and 2B are lpivqtally attached at their one end to the cross shafts 1-1 and I8 and the vertical frames liand -l 6.- The opposite ends 2| of the frames are-free tomove up and down.

The .cross shaft I 3 has crank arms 22 fixed thereon for'drivingthe connecting links 23, which the outerfree ends of the walking beams,

I- attach pedals 28 and 29 upon which the operator or operators of .the merry-go-round stand. Two

semi-circular platforms 30 are mounted on either side of the walking beams l2 to form part of the platforms 28 and 29. The platforms 30 are rockably mounted .on upright pivot supports .32, which, are secured to the cross frames 7 as best shown in Figures 3-and 6. These platforms move in unison with the Walking beams forming the main frameof the merry-go-round. I have not shown any seating'accommodations on the platforms '30 but any suitable seating arrangement may be provided within the annular walls 30A surrounding the platforms. Across the gaps between theends of the walls MA I may provide curved walls 31 serve as a back rest and protection to the i operator.

In :operating the device, one operator stands on the platform L29 with one foot, and places his other foot :on the pedal 33 located on the outer 7 ends'o'f the-A- frames 'l 9,'by placing the weight on the ip'edal-andtaking the weight off of the .platform the Aeframe l9 transfers the Weight of'the operator from the :pedal end 2'! to its opposite end, which is :mounted upon the cross shafts l1 and i8. Thisplaces the weight on the vertical frame L6, thereby lowering this frame assembly together with -the-platform 2B. As the Wei ht waszplacedonithe pedal 33 with the one foot of the operator and the weight was relieved from the other foot, it permitted the frame assembly l to raise up with the walking beam, at the same time this operation takes place another operator may assist by putting his weight on the platform 28 and allowing the A-frame 20 and its pedal to raise. This of course assists the efforts of the first operator. As the pedals 33 are pushed down and the A-frames travel down vertically, the connecting links 23, which are pivotally connected to the cranks 22 causes the cross shaft l3 to rotate, rotating the driving gear or pinion 26, which in turn travels around the stationary gear 21, this in turn rotates the complete assembly about the vertical column I.

From the above description it will be apparent that a rotary motion is imparted by the operators to the merry-go-round and at the same time an up and down movement to the platforms.

While I have shown a particular form of em bodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1. Apparatus of the character described, consisting of a vertical supporting column, a platform rotatably mounted upon the column, walking beams pivotally attached to said column, op-' positely disposed A-frames attached at their one ends to the walking beams, the apex of each A-' frame terminating in a pedal, one leg of each A- frame being connected with a crank shaft provided with adriving gear operatively engaged with a fixed gear mounted upon said supporting around said gear, a pair of walking beams pivotally mounted on said frame for vertical movement, vertical members interconnecting the ends of said beams toform a parallel linkage, and means carried by said vertical members and extending along said beams to turn said crankshaft to rotate said frame by up and down motion of said beams.

6. A rotating apparatus comprising a stationary 7 gear, a crankshaft geared thereto, a frame carrying said crankshaft and mounted for rotation around said gear, a pair of walking beams pivotally interconnected for vertical parallel movement on said frame, a platform rockably mounted on said frame to follow the movement of said walking beams, and means for transmitting the vertical movements of the ends of the walking beams to said crankshaft to turn said crankshaft and rotate said frame and platform in response to up and down motion of said beams.
