SWING.

To all whom it may concern Be it known that'I, EMIL M. SPRicH, a

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 had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in swings, and the object of my invention is to provide a novel construction of swing having means whereby the operator may with a minimum of effort move the swing.

With the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as i will be hereinafter more fully described,

pointed out in the claims and illustrated in the accompanying drawings, 1nwh1ch- Figure 11s ilItGlGVfitlOIl of a swing constructed according to my invention; Fig. 2

. At the upper is a-front view of the swing; and Fig. 3 is a Fig. 1.

Referring by numerals to the accompanyingdrawings: 4 designates the seat which 1s. secured to an "inflexible suspending rod 5.

end of the rod 5 there is a link 6 which is preferably triangular shape.

This link is pivotally secured to a bracket 7 which is fixed to a supporting rod 8. EX-

tending forwardly from the bracket ,7 there is an arm 9 having at its free end a bearing 10 in which is pivotally mounted a rocker 11. Pivotally secured to the rocker 11 adjacent its outer free end there is a pitman 12 .having at its lower end a fork 13 which is arranged to straddle the swing rod 5. i 40 14 designates a sleeve which embraces the swing rod 5 and is free to move longitudinally thereof. Irojecting forwardly from said sleeve there is a stud 15 which is inserted through the fork 13, and impinging between said fork andthe sleeve 14 there is I an extensile coil spring 16. I

Secured to the rocker 11 is a. rope 17,

Y which extends to the seat 4 so that the 0perator on the seat may, by pulling downwardly on the rope, move the rocker 11 on its pivot 10. In moving the rocker downwardly a come 01 um patent may be obtained to:

pressure is brought to bear rearwardly on the swing rod 5 bythe pitman 12. p

18 designates a set screw carried by the sleeve 14 which is used to secure the swing against movement, either from the vertical position shown, or from a position swung to one side as when out of use.

It Wlll be observed that the rocker 11 is 1 shown as an open frame in order to permit a wide rangeof movements between thepitman 12 and the rocker, and it will be observed further that the link 6 is an open frame of greater width than the rocker 11 solthat the swing proper may move to positionsbeyond the horizontal, with the link 6 overlapping the rocker 11 and arm 9. 19 designates a means for limiting the movement of the swing and comprises pairs of hinged plates 20 and 21, the plate 20 being secured to the swing rod and the plate 21 bearing against the swing rod.

22 designates a spring which acts on the two plates. When the sleeve 14 engages the lowermost plates 21 the springs 22 will cushion or retard the movement of the sleeve.

I claim: I

1. In a swing, a bracket, arranged to be non-rotatively secured to an overhead support, an openlink pivotally secured to said bracket, a rod suspended from said link, a rocker of lesser dimensions than the open link .pivotally securedto the bracket, a pitman .pivotally secured to said rocker, a sleeve connected with said pitman andarranged to slide on said rod, and means for rocking said rocker, said open llnk capable of overriding the rocker when in operation.

2. In a swing, a swing rod,- a rocking element a pitm'an pivotally connected with the rocking element, a sleeve arranged to slide on the swing rod and connected with the pitman, meansfor rocking said rocking element and cushioning means for engagement with saidsleeve, for the purposes stated.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses. EMIL M. SPRICH. ,Witnesses: I

E. L. WALLACE, E. M. Hnnnmcfron.
