SEESAW AND ROTARY SWING.

Specification of Letters Patent.

latented Feb. 25 1908.

Application filed October 8. 1906- Serial No. 337.959.

T 0 all whom it may concern:

Be it known that I, ISAAC S. WoonwAno, a resident of Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Seesaw and Rotary Swings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to see-saw and rotary swing.

The. object is to produce a simple inexpensive and durable machine eliminating all dangerous features.

To the accomplishment of these objects and others subordinate thereto, the preferred embodiment of my invention comprehends the construction and arrangements of parts to be hereinafter described, illustrated in the accompanying drawings and succintly defined in the appended claims.

In the drawings Figure 1, is a perspective view of a swing embodying my invention. Fig. 2, a vertical section of thepedestal and swivel. Fig. 3, a toothed disk. Fig. 1, a dog. Fig. 5, the method of joining bars 2 and 2 together.

1, designates a pedestal on which is mounted a swivel and bars 2, 2 and 3. This pedestal is preferably cast iron and is flared out at the lower end to provide against toppling over, is circular in form and the underside thereof is provided with a recess 4, the top end of said pedestal is approximately the same shape as the lower end, the recess extending down further and progressively diminishing and abruptly terminating at 4. The top of this recess has annular indents 5 and 6. These indents are for reception of ball bearings 7. I provide a cast disk 9, about one half inch thick, with a round opening 11, in the center and an annular flange 12, nearthe perimeter, and on top of the said flange are teeth. 10. A cast swivel 13, having indents on the periphery thereof which are to engage the balls 7, when placed within the pedestal 1. This swivel progressively diminishes incontour from the balls down, the free end being provided with a countersink 15, which is for the reception of a ball 1.6. The top end of the said swivel is bifurcated to receive the bars 2, 2 and 3, and are pierced to receive the bolts 17, and 18, on these bolts bars 2, 2 and 3 are pivotally secured as seen in Fig. 1. A dog 19, is made of spring steel and has an indent 20, in one end, the other end 21, is flattened out and has a round opening 22, therein, to receive the bolt 23. These dogs are slightly curved. to provide resiliency under concussion. The object of the aforesaid indents is to permit the dogs to straddle the flange 12, and teeth 10. The bars 2, and 2 are cut away and joined together as seen at A, Fig. 5. The bar 3, is somewhat longer than the combined length of bars 2, and 2 which is for the reception of the seats 24, which are secured. to the bar by screws C. On either side of the free ends'of the bars are battens 25, and are pivotally secured thereto by the bolts 26, and rods 27. Holes 28, and 29, are made for the purpose of adjustment. The object of curving in the bars is to give the free end of the battens a reciprocal movement which is helpful to the riders in operating the machine. The free ends of these battens are pierced for the reception of the round rods 30, which rod is for the rider to hold on to. The round rods 27, serve the double purpose of pivoting the battens to the bars and the riders torest their feet upon. To the bars 2, and 2 are pivotally secured by means of bolts'23, dogs 19. When a rotative movement is not desired by the riders the dogs 19, can be dis engaged from the teeth 10, and made pendent from the bars.

Having described the details of construction of my machine I will now'describe the assembling and operation thereof.

The disk is placed on the pedestal and secured thereto by the bolts 8. A bolt 16, is dropped down in'the bottom of the recess 4", and the bolts 7, are placed in the indents 5, and 6, and the swivel 13, is then placed in the pedestal as seen in Fig. 2. The bars are mounted on theswivel as hereinbefore described, the dogs bolted to the bars and placed in engagement with the teeth 10. When two persons mount the machine and begin to move the free ends of the bars up and down it will be seen when the dogs engage with the teeth 10, the swing will be given a rotary movement as well as u and down. By reference to Fig. 2, it Wlll be seen the lower tier of bolts 7, and bolt 16, support the weight of the swivel the bars and the riders while the upper tiers support the swivel laterally.

Having described the construction of my machine what I claim and wish to secure by Letters Patent is In a see-saw and rotary swing, a pedestal bars said dogs having a detentin one end, an having interior recesses, a plurality of de- I annular disk with a flange haying teeth thereon, as set forth.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
