COMBINATION TEETER-TOTTER AND MERRY-GO-ROUND..

Application filed July 19, 1926. Serial No. 123,563.

connect the teeter to the merry-go-round in fsite sides of the frame2.

such manner that the oscillations of the former will effect the rotation of the latter about a vertical axis.

Another object is to provide mechanism for adjustably'balancing the oscillatory-teeter in order to compensate for the difference in weight of the passengers carried thereby.

Other features will hereinafter appear and in order that the invention may be fully understood reference will now behad to the accompanying drawings, in which? Fig. 1 shows the teeter in side elevation and the merry-go-round in vertical section.

Fig. 7 is a plan view of a balancing device which is adjustably mounted upon the teeter.

Fig. 8 is a detail of a pair of links and associate parts V Referring in detail to the different part-s, 2 designates a vertical supporting frame provided at its lower end with legs'4 rigidly mounted upon a suitable base 6, which in practice may be fixed 'upon a concrete or other suitable foundation.

8 designates an oscillatory teeter member mounted midway between its ends upon a shaft 9 which is mounted atits ends in oppo A bearing"10 serves to reliably hold the teeterjmember 8 in position upon .said shaft The teeter member Sis provided at its ends with seats 11. and steps 12 and '14. When the. teeter -member8 is tilted by a passenger occupying "one ofthe seats 11 the other high seat can be readily reached by means of 'the associate steps.

Thesteps '12 are fixed to the lower porv tions of :Ushaped hangers 16 depending from the teeter member 8, while the steps 14 are fixed to arms 18 rockably mounted upon pivots 20 arranged in the lower portlons ofthe hangers 16. Normally the steps 14 and the arms 18 are held in raised position as shown by Fig. 6, by coil springs 22 mounted upon the pivots 20 and having one end engaging the transverse lower portions of the hangers 16 and their opposite end engaging rods 24 connected to the arms 18. 26 designates a balancing device to compensate for the diiference in Weight of the persons carried by the teeter member 8.

Said balancing device 26 consists of a frame 28 and roller weights 30, which lattertravel upon the teeter member 8. The teeter member 8 may be" provided with any suitable means for preventing lateral or vertical dis- 1 placement of the frame 28. In the present instance I have shown said teeter member 8 provided with oppositely disposed plates32 having lugs 34 which overlap the frame 28 as more clearly shown by Fig. 5. The mechanism for shifting the balancing device 26 longitudinally upon the v teeter member 8 consists of handles 36, bellcranks 38 to which the handles 36 are fixed, links 40 connected by a transverse. pin 42, and a plate pivotally connected to the lower ends of the bell cranks 38 and having their free ends 44 projecting upwardly from the intermediate ,portion of the frame 28 and provided with a series .ofvertical notches 46, any of which are adapted to receive the pin 42. The bell cranks 38 are mounted upon ful-' crums 48carried at the upper ends of the longer arms ofU-shaped fittings 50 secured to theteeter member 8 at opposite sides of the notched plate 44.

Having described the teeter and the balancing means therefor, I Wlll now proceed to. descrlbe the merry-go-round and the mechanism whereby itis rotated whenv the teeter is operated. As shown by Figs. 1 and 2, the merry-go-round embodies a skeleton rotary frame consisting of radially disposed 1 arms 52 and braces 54. The arms-52am connected at their inner ends to a cap 56 and provided at their outer ends with hangers 58 from which rods 60 are suspended for the purposeof carrying seats 62. v

The cap 56 is mounted upon a vertically disposed rotary shaft 64, which is journaled in the top 66 of the frame 2 and the bearing 68 of a cross bar 70 fixed to the opposite sides of the frame 2, Figs. 1 and 3. The braces 54: are secured at their outer ends to the arms 52 and at their inner ends to a revolvable head 72 supported upon a series of balls 74 whichare disposed in a circular ball race in the upper portion 66 of the frame 2.

The shaft 64 is provided with a fixedly mounted bevel wheel 76 which interm'eshes with diametrically opposed bevel wheels 78 and 80fixedly mounted upon shafts 82 and 84: journaled in bearings 86 and 88, respectively, carried at opposite sides of the frame 2.- The shafts 82 and 8 1 are provided with fixedly mounted cranks 85 and'8'? which are operably connected to the upper ends of connecting rods 90 and 92 which are pivotally connected at their lower ends to cross heads 94 and 96, respectively. V

V The cross heads 94 and96 operate in slideways 98 and 100 fixed to opposite sides of the frame 2, and said cross heads 94 and 96 are pivotally connected to the upper ends of links 102 and 104, which in turn are operably connected to short arms 106 and 108 of the respective U-shaped fittings 50. As shown more clearly by Fig. 8, the links 102 are arranged in-pairs and one is provided at its lower end with a. laterally projecting stud 110 adapted to extend through an eye 111 in the upper end of the arm 106. In making the connection the links 102 are spread apart to pass over the opposite sides of the arm 106, after which the stud 110 is passed through the eye 111 and into the eye in the lower end of the companion'link 102, whereupon asleeve 112 is slid downwardly upon the links to keep them from spreading apart and withdrawing the stud 110from said eyes. The links 104 are connected to the arm 108 in the same manner as the links 102 are connected to the arm 106, as is evidenced by corresponding reference numerals with exponents a. v v

VVith the parts'constructed and arranged as shown and described it is apparent that when the teeter is oscillated by passengers occupying the seats 11, rotary motion will be imparted to the merry-go-round through .the intermediary of the intervening mechanism. i While I have shown and described theprelferre'd construction, combination and arrangement of parts, I reserve all rights to such changes-and modifications as properly fall within the spirit "and scope of the in 60 vention as claimed.
