- Specification of Letters Patent.

Application filed August 26, 1918, I Serial No. 117,080.

To all whom it may concern:

Be it known that I, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Swings, of

which the following is a specification containing a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention relates to improvements in swings, and has for its object the construction of a swing which is of simple and in-' expensive construction, which operates at a minimum of effort, and in which the danger of injury to its occupants is minimized.

To the above'purposes, my invention consists in certain novel details of the construction and arrangement of parts which will be fully, clearly and concisely set forth in my specification, specifically designated'in my claims and illustrated by the accompanying drawing, in which Figure l is an elevation of a swing embodying my improvements;

- Fig. 2 is an endelevation of the swing;

Fig. 3 is a plan of the upper frame of the swing with the supports removed;

Fig. 4 is a sectional plan taken on the line 1 iof Fig. 1 of the swing body only; and

Fig. 5 is a detailed perspective. of one of the operating levers.

Referring by numerals to the accompanying drawing, I

6 designates the upper frame, which comprises two parallel bars 7 and 8, which are relatively spaced by the blocks 9, and which, together with the blocks, are held together as a unit by nails or other means not shown. To the ends of this upper frame 6 there are secured the supports 10, which are by preference to increase the base, inclined 'downwardly both longitudinally and laterally of the structure.

In order to prevent spreading of the supports longitudinally, I provide the crossed braces 11, which are united intermediate their ends by means of a bolt 12, one end of each brace being connected to the frame 6 by means of a bolt 13 and the other end of each brace being connected to the support 10 by means of a bolt 14:.

Between certain of the spacing blocks 9 of the frame 6 I pivotally secure the hangers 15 and 16, the spacing of the blocks 9 permitting a swinging motion of the said hangers. Y Pivotally secured to the hangers 15 STEPHEN A. DOUGLASS,"

' and 16 and removed from their lower ends are the seat rails 17. By preference there are two of these rails, which, like the frame 6, are spaced by blocks 18, between certain of which the hangers 15 and 16 are pivoted. In the hangers I provide a series of perforations 19, and through the rails 17 there are alining openings through which bolts 20 are extended, the plurality of openings 19 aiford. ing a vertical adjustment of the rails 17, the pptrpose of which will be made clear hereina or.

Secured over the top of the rails 17 and arranged transversely thereof are the seats 21, 22, 23 and 24, there being brace blocks 25 extending from the seat to 'the outside lateral faces of the rails in order to prevent tilting of the seats. Pivotally secured to the hangers 15 and 16 beneath the rails 17 is a foot rest or platform 26, upon which the operators or passengers may rest their feet,

and which serves the double function ofmeans for propelling the swing and holding the passengers feet elevated to prevent injury by strikin stationary objects upon the supporting sur ace.

It is to be observed that the hangers 15 and 16 are parallel and normally vertical, and it will be observed that the seat rails 17 and the foot rest or platform are horizontal Patented Jan. 29, 1218.

and normally at right angles to the hangers.-

' In order to distort or change this angular relationship of the elements just recited, the

operators, by their feet resting upon the platform, in pressing in one direction upon the seats or rails and in an opposite direction on the foot rest or platform, distort this angular relationship referred to and thereby set in motion the hangers or the entire swing body.

In order to facilitate the movement of the swing, I provide at the approximate longitudinal center of the foot rest'or platform a foot brace 27, upon which the operators occupying seats numbers 22 and 23 place their feet, and for these two operators I provide the hand levers 28 and 29, which are pivotally secured to both seat rails and foot rest or platform. These two levers are provided like the hangers 15 and '16 with a series of openings so that the entire frame, comprising the two seat rails and all of the seats, may providing for different sized operators. It will be apparent that when the operator occupying seat number 23, with his feet on nasaeeo the brace 27 and exerting pressure on the brace in a forward direction, to the left in Fig. l, and pulling rearwardly upon the lever 29 to the right in Fig. 1, will distort the right angular relationship between rail 17, foot platform 26 and the hangers l5 and 16, thereby imparting a swinging motion to the entire swing body from the hangers l5 and 16. In this manner and in replica of the operation just described, the operator on seat 22 assists the swinging motion.

' 011 each of the hangers I provide handles 30, which may be grasped by the operators on seats numbers 21 and 2 1, through which, and through their feet resting upon the platform 26, each may assist in the swinging motion, so that if desired any one or all of the operators may move the swing.

In order to prevent lateral spreading of the supports 10 I provide the cross pieces 31, which cross pieces also serve as a means for limiting the swinging motion of the swing body in the engagement of the hangers l5 and 16 therewith.

As clearly shown in Fig. 5, the levers 28 and 29 may each be provided with a handle 32, and this handle may be vertically adj ustably connected with the lever by means of the holes 33 in the lever and bolts 34 extended the-rethrough.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States therefor, is:

1. A swing comprising a supporting frame, a pair of parallel and normally vertical hangers pivoted to said supporting frame, an adjustable seat rail pivotally connecting said hangers, seats mounted on said seat rail between and outside of the hangers,

a platform pivotally secured to the hangers and positioned below the seat rail spaced apart therefrom, and parallel therewith, a lever pivotally connecting the seat rail and platform and positioned between the hangers, and an adjustable operating handle carried by said lever.

2. A swing comprising a supporting frame, a pair of parallel and normally vertical hangers pivoted to said supporting frame, an adjustable seat rail pivotally connecting said hangers, seats secured to said seat rail between the hangers, a seat secured to each end of the seat rail outside of the hangers, a platform pivotally secured to the hangers and positioned below the seat rail spaced apart therefrom and parallel theresecured to said support, a platform pivotally connecting'the lower ends of the hangers, a foot brace secured to said platform between the hangers, an operating lever pivotally secured to said platform between the foot brace and one of the hangers, an adjustable seat platform spaced apart and located above the platform and parallel therewith and pivotally secured to said hangers and lever, a seat carried by each end of the seat platform outside of the hangers, a seat carriedby the seat platform between the operating lever and one of the hangers, and an adjustable operating handle for said operating lever.

4-. A. swing comprising a supporting frame, a pair of parallel and normally vertical hangers pivoted to said supporting frame, an adjustable seat rail pivotally connecting said hangers, seats mounted on said seat rail between and outside of the hangers,

a platform pivotally secured to the hangers and positioned below the seat rail spaced apart therefrom, and parallel therewith, a lever pivotally connecting the' seat rail and platform and positioned between the hangers, stops secured to the supporting frame for limiting the outward movement of the hangers, and an adjustable operating handle carried by said lever.

5. A swing comprising a supporting frame, a foot platform, an adjustable seat platform positioned above the foot platform and parallel therewith, a pair of operating levers pivotally connected to the foot platform and seat platform, seats carried by the seat platform, a foot brace carried by the foot platform between the operating levers, and a single hanger pivotally connecting the foot platform and seat platform and located centrally of the widths of said platforms.

lln testimony whereof, l have signed my name to this specification, in presence of two subscribing witnesses.
