UNITED STATES PATENT OFFICE.

WILLIAM w. ELLIOTT, or GALVESTON, TEXAS.

SWING.

SPECIFICATION forming part of Letters Patent No. 320,432, dated June 16, 1885'.

Application filed November 21, 1884.

To all whom it may concern:

Be it known that I, WILLIAM W. ELLIOTT, of Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements in 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in swings; and it consists, first, in the combina tion, of a single upright or hanger, to the lower end of which the swing is secured,a screw-hook, by means of which the hanger is suspended, and suitable castings which catch upon opposite sides of the upper end of the upright for the purpose of steadying the upright in its place 5 second, in the combination of a single upright or hanger with a slotted lever which is provided with a friction-roller to bear against one edge of the hanger, and with a second friction-roller at its lower end for the operatingcord to pass over, the lever being made to increase in thickness from its lower end upward, all of which will be more fully described hereinafter. I

The object of my invention is to provide a swing which consists of a single upright or hanger and a mechanism by means of which the person sitting in the swing has but to pull upon the cord and cause the swing to freely move back and forth.

Figure l is a side elevation of a swing embodying my invention. Fig. 2 is a front view of the same.

A represents a suitable support or frame in which the swing is to be suspended, instead of a frame which is made especially for the purpose. The swing may be suspended from the ceiling or any other suitable support. The single hanger or standard B is supported at its upper end by means of a screw-hook, D, which has its lower end made L-shaped, so as to pass through the upper end of the hanger, as shown.

In order not only to hold the hanger in place, but also to guide and steady the movement of the hanger, a suitable casting, D, is placed upon each side of the upper end of the (No model.)

hanger, as shown. These castings serve to prevent any lateral play or vibration of the hanger as it swings back and forth. At a suitable distance below the upper end of the hanger a suitable enlargement, E, is formed upon its side, for the purpose of enabling the operating lever to give the hanger a greater throw or movement.

Secured to the front edge of the hanger is a suitable metallic plate, G, which passes up over the top of the hanger and down upon its opposite side, for the purpose of strengthening the hanger, and for the friction-roller of the operating-lever to bear against without wearing out or injuring the hanger itself.

Through the hanger, at any suitable point, is madea suitable slot, and in this slot is pivoted a friction-roller, H, under which the operating-cord passes.

' To the lower end of the standard is secured a swing, which may be of any suitable con struction.

The operating-lever K is slotted for the greater portion of its length, and is pivoted or suspended at its upper end, in any desired relation to the upper end of the hanger, in a suitable casting or support, I. J onrnaled in the slot in this lever is a friction-roller, J, which bears against the metallic plate on the front edge of the hanger, as shown. J

In the lower end of the operatinglever is journaled a second friction-roller, over which the operating-cord passes. This operatingcord is fastened to the support A, passes down under the friction-roller that is journaled in the hanger, up over the friction-roller that is journaled into the lower end of the operatinglever, and then down to the person in the swing. When a pull is exerted upon the lower end of this rope, the lower end of the lever is drawn downward, and in doing so the hanger is forced backward. As soon as the tension upon the cord is released the gravity of the swing causes it to swing forward again, when a second pull upon the lever forces it backward again.

The width of the operating-lever is made to increase from its lower to its upper end, so that the hanger can pass freely through it, as shown. The increase in width upon the front edge of the hanger enables a quicker and a greater amount of movement to be imparted to the hanger than can be done where the hanger is of a uniform width.

I am aware that the upper ends of the hangers of a swing have been pivoted between the ears of castings; but these ears do not hold the ends of the hangersnpon the pivot upon which they are placed, and this I disclaim.

Having thus described my invention, I claim- 1. The combination of a suitable support, a suspension-hook, a single hanger, and suitable castings, which are applied to opposite sides of the upper end of the hanger for the purpose of guiding its movement, substantially as shown.
