SWING Filed March 18. 1932 2 Sheets=5heet 2 Inventor f Jnaazem/y/r/ By 2 mm Patented Jan. 3, 1933 UNETE STATES ATENT FFIE JULIUS JAN USZEWSKI, OF MIDDLE VILLAGE, LONG ISLAND, NEW YORK SWING Application filed March 18, 1932. Serial No. 599,792.

The present invention relates to a swing being provided on each of said rails, one particularly for small children and has for adjacent each end. The hangers are provided its primary object to provide, in a manner with out-turned, headed upper end portions as hereinafter set forth, a device of this charwhich are journaled in the rails 2.

It will thus be seen lowing specification, taken in connection with hat the upper portions of the levers 12 are the accompanying drawings wherein like disposed inwardly of the side walls and the characters of reference designate correspondlower portions thereof are disposed outing parts throughout the several views, and wardly of said side walls. A handle bar 14 wherein is mounted transversely on the upper ends of Figure 1 is a perspective view of a swing the levers 12 through the medium of the constructed in accordance with the present y'okes 15. invention looking toward the rear portion of Bell crank levers 16 are mounted for swingth i mg movement in a vertical plane on the rear Fi 21 a tiv i th of 1 kportions of the rails 2 between said rails and ing towards the front portion. the body 6. Each bell crank lever 16 has Figure 3 is a perspective View showing a mounted at its lower end a pair of grooved portion of the actuating mechanism, a part rollers 11 engaged with opposite sides of the of said mechanism being shown in section. adjacent hanger 5, thereby connecting the bell Fi r 4 i a detail i w in vertical s ction crank levers thereto for actuating said adjashowing the means for mounting the handle cent hanger. Each bell crank is formed of on its supporting levers. wire having its intermediate portion coiled to Figure 5 is a vertical sectional view, taken provide a number of convolutions, as shown substantially on the line 5-5 of Figure 1, at 16, and a bolt 16" passes through said coils looking forward. and enters the rail 2.

Referring now to the drawings in detail, A sectional pitman which is designated genit will be seen that the combination of the orally by the reference numeral 18 operainvention which has been illustrated comtively connects the upper end of each bell prises a supporting structure which is desigcrank 16 to the lower end of a lever 12 for acnated generally by the reference numeral 1, tuation thereby. Each pitman 18 includes a said supporting structure including the comparatively long lower section 19 and a spaced, parallel rails 2 which are rigidly secomparatively short upper section 20, said cured on the upper end portions of the upsections 19 and 20 being resiliently connected wardly converging front and rear pairs of together through the medium of a joint legs 3. Braces 1 extend transversely between which comprises a socket 21 on the upper end the lower portions of the front and rear pairs of the section 19 into which the section 20 of legs. slidably extends. A flange 22 is provided at Suspended for swinging movement from the lower end of the socket 21. A flange 23 the rails 2 are the hangers 5, two hangers is provided on an intermediate portion of the v mounted on the hangers,

section 20. Then, the resilient section oint further includes an exp ansibleand compressible coil spring 2A which encircles the socket 21 and the adjacent portion of the section 20 and 3 has its ends anchored in any suitable manner to the flanges 22 and 23.

In use, as will be apparent,the body may be caused to swing back and forth by the occupant thereof by simply rasping and shifting the handle bar 14, thereby swinging the levers 12. the pitmans 18 and the bell crank levers 16 to the rear hanger 5. Stops 25 project from the side walls 7 for engagement by thelevers 12 to limit the swinging movementoi-said levers.-

he coil portions of the bell cranksimpart resiliency to said bell cranks so that when the body is swinging too violently the bell cranks through their resiliency will act as shock absorbers andresist the swingingmovement and thus cause the swing or device to work smoothly back and forth. The, spring forming portions of the pitmen 18 also act as shock absorbers and tion of the device.

It is believed that the many advantages of a swing constructed in accordance with the present invention will be readily understood, and although the preferred embodimentof The movement is transmitted through insure a smooth opera mounted on the hangers, a resilient bell crank lever pivotally mounted on the supporting structure and having rollers at one end operatlvely engaged with one of the hangers for actuating the same, a lever pivotally mounted on the body, and resilient means connecting v JULIUS AnUszEws the invention is as illustrated and described,

it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed. w l

' What is claimed is i 1. A swing comprising a supporting structure, hangers mounted for swinging movement on, the supporting structure, a body mounted on the hangers, and means operable by an occupant of the body for causing said body to swing, said means including a resilient bell crank lever pivotally mounted on the supporting structure and operatively engaged'with one of the hangers, a lever pivotally mounted for swinging movement on the body, named lever to the second named lever for actuation thereby. V 7 I 2. A swing comprlsing a supporting structure, hangers mounted for swinging movement on the supporting structure, a body lever pivotally mounted on the supporting structure and operatively engaged with one of the hangers for actuating the same, a lever pivotally mounted on the body, and a pitman connecting the bell crank lever to the second named lever for actuation thereby, said pitman being formed of two sections and resilient means connecting the two sections together, I

3. A swing comprising a supporting structure, hangers mounted for swinging movement on the supporting structure, a body a resilient bell crank and a pitman connecting the first pivotally connected, at one end, to the second named lever,
