To all whom it may concern:

Be it known that I, James A. TERRY citizen of the United States of America, and resident of Pocahontas, Pocahontas county,

Iowa, have invented a new and useful Amusement Afipparatus, of which the followin is a speci cation.

he ob ect of this invention is to provide an improved construction for an amusement apparatus particularly adapted for use by children.

- A further object of this invention isto provide an improved amusement apparatus combining the characteristics of a seesaw or teeterin device and a merry-go-round or carouseh A further object of this invention is to provide im roved means in an amusement apparatus or effecting a rotary movement through and because o a vertical oscillating movement.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the'accompanying drawing, in which I Figure 1 is an elevation of myimproved apparatus. Fig. 2 is a plan 0 the same. Fig. 3 is a central vertical section of the same, transversely of the beam, on an enlarged scale. Fig. 4 is a cross-section showing the pivotal mountingof the rocking devices, on a further enlarged scale. Fig. 5 is a cross-section on the line 5-5 of Fig. 2, on

an enlarged scale. Fig. 6 is a cross-section on the line 66 of Fig. 2, on an enlarged scale. Fig. 7 is an end elevation of the beam and a seat thereon.

In the construction of the dance as shown the numeral 10 designates a support such as a post 10, which may be formed of metal with a base 11 adapted to be-seoured in any desired and suitable location. The sup ort 10 also may be formed with a head or p ate 12 at its top. If desired, the post 1 0 ma be of wood, the "base 11 of concrete, in whic the 0st is set, and the plate 12 of metal suita ly secured to the top of the ost.

The plate 12 preferably iscircu ar and is formed with an integral, peripheral, upstanding track 13, the surface of said track bein in a constantly changin plane, which may said to be abruptly un ulating, comprisin a series of elevations or upwardly curve members with intervening depressions. A pivot bolt or spindle 14 is mounted a: A. arm or rocanomr, Iowa.

vertically centrally of and rigidly secured in the plate 12 and rises somewhat above the plane of the greatest elevation of the track 13. A hub 15 is mounted for rotation on the spindle 14 and may also have a'sli ht vertical movement thereon, the spindle e- "are indicated by the numerals 19, 20. A frame 21 is fixed to the lower side and in the' central portion of the beam members 19, 2D and connects said members ri 'dly, and said frame is formed with space downwardly projecting flanges 22, 23, and are journaled on the trunnions 18. Thus the rocking beam is adapted for vertical oscillating movement, by articulation of the flanges 22, 23 on the trunnions 18, and for rotary movement through articulation of the hub 15 on the spindle 1 1. Rollers 2 1, 25 are said flanges.

journaled for rotation on horizontal axes,

longitudinally of the beam 19, 20 and are arranged .on opposite sides of the center thereof and spaced to correspond to the diameter of the track 13, on which track said rollers are adapted to ride. The points or elevations of the track 13 are of an uneven number and equally spaced apart, whereby a point or elevation is diametricall op 0- site to a depression of said track. %y t is arrangement it is necessary that when one of the rollers 24, 25 is on top of'one of the elevations of the track, the other of said rollers is in the bottom of a depression, and the beam members 19, 20 therefore occupy an inclined position; and when said beam members are in horizontal position the rollers 24, 25 are in positions of unstable equilibriumintermediate of the highest and lowest portions of the track. It will be apparent that because of the construction and arrangement above described, any movement of vertical oscillation of the beam will result'in a rotary movement, and any force tending to cause a rotary movement will also result in a vertical oscillating move- I by a bolt 34 to the wedge A to . beam:

movement.

. -tionally-enga e'the clamp 33 thereb venting long itudinal movenient of merit, so that the device cannot be operated without a combined rotary and oscillating I have provided a 'clampin late26 overlying the central portions 0 t e beams 19,

20 and clampin said beams to the frame 21 cs 28 embrace the beams 19, 20 adjacent by means of olts 27. Other clamping at Ehe pomts where-said beams meet near their ends, and are secured by bolts 29.

The rocking beam formed as above described is rigid longitudmally, as contradistinguished to a device made up of longitudinall arranged sections pivoted together,

and osc' latesin a common transverse plane.

Seats 30, 31, which maybe formed of metal by bendmg and-pressing, or in any other suitable manner, aremounted on end portions of the beam formed by the membore 19, 20, and either or both of said seats may be adjustable longitudinally of the beam. In the accompanying 'drawm I have shown a wedge member 32 secure to and projecting downwardly from the battom of each seat 30, 31 and having its pomt or wedge resting between the beam members 19, 20. A clamp 33 is pivoted atits ends member 32 and en- .c1rcles and embraces t e beams 19, 20, and said pivot is forwardly of the longitudinal center of said wedge member and of the tween the beams 19, 20, the pressure on the clam is released, and the seat may be adjuste longitudinally of the beam, such adjustment in a direction toward the center of the device being limited by engagement with the clamps 28, and outwardly by plates'35,

Fig. 7) overlying and closing the ends of t e tubular beams 19, 20. It is to be understood that any other'suitable means may be employed for securing the adjustment of either or both of the seats 30, 31, if desired, such as the useof set screws engaging the A strut'36 is fixed centrally toand rises from-the frame 21 between the beam membars 19, 20, and a truss rod or wire 37' is provided and engages in its central portion the u per end ofsaid strut. The truss member 3 extends longitudinally of the beam and passes beneath the clamps 28 and beneath the beam members adjacent said clamps, then extends outwardly beneath said beam members and through the end plates 35, being threaded on its'ends and secured by nuts 38 contacting with the outer faces of said plates. Thus provision is made for strengthening, stifi'emng', bracing and reinforcing the beam, and for adjusting the tension of said trussing devices.

The device makes an attractive playground apparatus which is com arative safe and easily operated,-as a slig t swinging or teetering movement is sufficient to start the rotary and oscillating movement, and the state of unstable equilibrium by reason of the double 1pivoting and the staggered abruptly undu ating-track causes the momentum to carr the beams in their double movement wit .very little eifort. The device ma be adjusted to fpersons of varying sizes y adjustment 0 one or both of the seats so that the leverage on the opposite ends is approximately equal.

I claim as my invention-.
