SWING.

SPECIFICATIGN formingpart of Letters Patent No. 283,388, dated August 21, 1883.

Application filed July 11, 1882.

, exact description of the same, reference being had to the accompanying drawings, forming a part of this specification. a

The object of this invention is to produce a swing which can be moved by friction instead of by the user of the swing, as has been done heretofore.

Referring to the drawings, Figure 1 is a front View of aswing embodying my invention. Fig. 2 is a sectional view of the same.

A is a longitudinal shaft supported in up right frames B B. On this shaft is fastened the wheel C. v

D is the swingcradle, supported on the arms F F, journaled to the shaft A, and this cradle is provided with a seat orseats, G.

H is a cross-pieee supported between the arms F F. To this cros's'piece is attached the spring friction-belt J, made of metal or any other material. To the free end K of the friction belt or band J is attached a rope, M, which extends down to within reach of the occupant of ,the swing-cradle To. use my invention the first thing to be doneis to cause the shaft A to rotate, carrying the wheel 0. This can be done by steam,'or by any power which will most cheaply accomplish the same, and must be continued as long as the swings are to be used. The person using the. swing then gets into the swing-cradle, and, by pulling the rope M, brings the friction belt or band J down upon the revolving wheel 0.

, By doing so enough friction is created to cause the swing to move in the same direction as the Renewed July 523, 1883. (No model.)

revolving wheel C on the shaft A. Now, when the swing-cradle has been raised high enough in the air, the occupantslackens the rope M, the wheel 0 is released from the pressure of the friction-belt J, and the swing is released and allowed to fall or swing back. To raise the swing again the occupant has to pull on the rope M again, and the swing will repeat the movement. I

By this construction a swing can be moved with much less labor to the user. Heretofore all swings have had to be used and raised by the laborious exertions of the user. By this invention the occupant can raise theswing as high as he wishes it to go, and to do it requires only the labor of pulling the rope M to give the required friction. 4

I do not wish to confine myself to the use of the friction belt or band J as a means of oreating friction, as I am aware that other and equivalent means can be used to accomplish the same result.

Having thus described my invention, I desire to claim- '1. The combination, in a swing, of the shaft A, carrying the wheel 0, and the swing-cradle D, suspended by the arms F F, with the crosspiece H, substantially as and for the purpose set forth. v

2. The band J, or its equivalent, in combination with the wheel C- on the shaft A in a swing,'said band being used substantially as and for the purpose set forth.
