SPECIFICATION forming part of Letters Patent No. 333.553, dated May 29, 1588.

Application filed November 7, 1887. Serial No. 254518. (No model.)

To a/ZZ whom t may concern:

Be it. known that I, ALEXANDER Barras, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvemcnts in Swings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to swings having a single suspending bar; and it may be said to consist in the devices and the peculiar combination and arrangement of devices hereinafter set forth7 and pointed ont in the claims.

In the drawings, which illustrate the manner of carrying out my invention,`Figure l is a front elevation of a swing embodying my in vention, and Fig. 2 is a side elevation of the same.

A B represents a suitable frame in which the swing is suspended, and which may be moved around from place to place, as may be required, the swing being especially designed for use in gymnasiuins as a means of exercising, the construction being such as to give substantially the same motion to the arms of the operator as he would make with them in using dumb-bells. II would say, however, that the swing may be suspended from the ceiling or anyothersuitablesupport. rIhesinglehanger C is pivoted by means of' bolt D to the support A, so that the suspending-bar C and the hanger may be swung sidewise, as indicated by dotted lines in Fig. l, this'construction preventing the possible breakage of said hanger or the upper end of bar C', as would occur were said hangers not pivoted to the support A.

Formed integral with the lower portion of hanger C, and extended beneath the support A, and a considerable distance to oneside thereof, is an arm, E, which carries a roller or sheave, E', at its outer end.

The upper end of suspendingbar C' is pivoted at et to arm E at a point that is immedi ately beneath supportA, and a horizontal bar, K, carrying seats LL, is secured to the lower end of said bar at right angles thereto.

Iwo foot-rests, O, consisting of a short bar of wood or metal, are bolted or otherwise secured to the lower portion of bar C in diierent planes one above the other, so there will be a foot-rest for the occupant of each seat.

The suspending-bar C can be made of asingie piece of material, or it can be madein two pieces, as here shown. If so desired, I may omit one seat from the swing, and its operation will be substantially the same as with two seats. About two feet from the pivotal point a, I locate a bracket, F, on bar G', so as to project at a right angle thereto, and provide said bracket with a roller, G, at its outer end. Qperating rope or cord J has its upper end attached to a spiral spring, I, and said spring` is connected to the side of bar C at a point that is'about opposite the location `of bracket F. Any suitable device-such as an eyebolt, I-I, or a hook-can be used for securing the lower end of spring I to the bar C. One end of the operating-cord J is connected to the upper end'of spring I and then passed over roller E', carried by an arm, E, and thence down over roller G, carried by the outer end of bracket F, and its outer end hangs low enough to be conveniently reached by the operator of either seat.

In some cases I may dispense with the use of spring I and attach rope J directly to eyebolt H, its function being mainly to take up the slack ofthe rope which occurs between each stroke of the operators arm, and to raise the operators hands as high as possible in order to give them a similar motion to that which they would make in exercising with .dumbbells, as I have found such to be very beneiicial and desirable.

The operation of the swing is as follows: When a downward pull is exerted on the lower end of rope J, the bar C is drawn toward the left-hand in Fig. 2, and as soon as the tension upon the rope is released the weight of the swing causes it to moveforward again, and so on. At each-pull upon the rope the spring I is distende'd, and when the operator desires to release the tension he must raise his hands con siderably higher than he would were the spring not made use of.

I-Iaving thus described my invention, what I claim isl. The combination of a suitable support, a single hanger secured thereto, a suspendingbar carrying a seat or seats at its lower end, and the upper end of which is pivoted to said hanger, a bracket located on said bar intermediate of the seats and its pivotal point, a roller IOO carried by said bracket, an arm projecting from said hanger on the opposite side of said bar to that upon which said bracket is located, and a cord or rope connected to the said suspendingbar at a point intermediate of the seats and its upper end and passed over a roller carried by the outer end of said arm, and also over the roller carried by the bracket, substantally as set forth.

2. In aswing, the hanger C, pivoted to support A, and havingarm E formed integral therewith, roller E', located in the outer end of said arm, in combination with suspending bar C', the upper end of which is pivoted to said hanger, bracket F,projected from one side I 5 of said bar, roller G, carried by the outer end of said bracket, spring I, having one end connected to said bar, and cord J, connected to the other end of said spring and passed over said rollers, substantially as set forth.

In testimony whereof I aix my signature in presence of two witnesses.

ALEXANDER BETTES.
