INDOOR SWING.

Specification of Letters Patent.

Patented Apr. 19, 1910.

Applioation flled September 7, 1909. Serial No. 516,519.

' a simple and convenient portable swing that can be quickly and securely put up for use in a doorway of a room, and as readily taken down when required.

. A further object'of the invention resides in providing a swing of the character named with an improved construction for suspending the seat body from the support thereof and to this-end consists in the details of construction and in the arrangement and combination of parts to behereinafter more fully set forth and described.

In describing the invention in detail reference will be had to the accompanying drawings in which like characters of reference denote corresponding parts in the several Views, and in which,

Figure 1 is a front elevation of a door frame showing the improved swing secured therein, a portion of the supporting rod of the swing being in section; Fig. 2, a fragmental detail view showing the connection between the supporting rod and the suspension members which carry the swing seat at theirfree ends; Fig. 3, a view similar to Fig. l with a portion of the connection shown in section; Fig. 4, a detail fragmental View showing one of the seat supporting rods which are secured to the free ends of corresponding pairs of suspension members, and the connection between said rod and said members, one of said connections being shown in section; and Fig. 5, a section on the line 5-5 of Fig. 3.

Referring to the drawings, A represents generally the swing support, B the suspension members and C the seat supporting rods which are carried by the said suspension members at their free ends. The support A. consists of three telescoping parts 1, 2 and 3. The parts 1 and 3 are of tubular formation and may be constructed of any suitable material. The outer end of each of the parts 1 and 3 is provided with a friction orabutting block 4, which have their outer faces provided with a layer of suitable flexible material, preferably indiarubber, whereby injury to the door casing between which the device is secured will be prevented. These blocks may be made either round, square or of any suitable shape. The inner wall of the tubular portion 3 is provided with an internal thread 5 into which is adapted to be secured a threaded end 6 of the part 2. The inner wall of the part 1 is plain and the end 7 of the part 2 is adapted to telescope into. the part 1. Intermediate its ends the part 2 is enlarged to form a. projecting annular portion 8 the outer face of which registers with the outer face of the parts 1 and 3. An aperture is formed transversely through the enlarged portion 8 in the part 2 and has passed therethrough a handle 9. It will thus be obvious that by rotating the part 2 through the medium of the handle 9 the parts 1 and 3 may be forced away from each other by reason of the threadedv engagement between the inner wall of the part 3 and the threaded end 6 of the' part 2 and the blocks 4 pressed against the door frame with great force so as to frictionally sustain the support A therebetween and thus effectually vious that a rotation of the part 2 in the other direction will release the blocks 4: from engagement with the door frame and easily permit the removal of the swing.

Dependin from the under side of the outer face 0 the parts 1 and 3 are the spaced ears 10 and-11 and journaled between said ears on the bolt 12 is a sleeve 13 provided with the flanged ends 14 and 15 to form a central reduced portion on said sleeve. On

suspend the swing. It will be equally obthe lower side of said sleeve is formed a lug 16 for a purpose to be hereinafter described. Passed around the central reduced portion of the sleeve so as to form an eye are the upper terminals of the suspension members 17 and 18. Between the upper terminal of w the suspension member 17 and the body portion thereof upon. which said terminal is bent there intervenes the lug 16 previously described. It will thus be obvious that any swinging movement imparted to the suspension members will produce a rotation of the sleeve 13 and that no independent movement between said suspension member 17 and the sleeve 13 can be had. It will be equally obtion of the member 18 with respectto the sleeve 13 can result. A nut 19 working on the threaded end of the bolt 12 serves to se-' cure the connectionjust described to the support A. By preventing any independent movement of the suspension members 17 and 18 with relation to the sleeve 13 a substantially noiseless swivel connection is had as the journal bearing between the sleeve and the bolt may be oiled and a swinging movement had Without undue squeaking. The lower ends of each pairof suspension members 17 and 18 are formed with eyes 20 and 21 adapted to receive the reduced ends 22 of a seat support 23. The reduced end portions 22 of the seat support 23 have their outer ends threaded for the reception of nuts 24 adapted 'to lock the suspension members 17 and 18 in assembled relation therewith. The seat support 23 is provided with transverse apertures 25 adapted to receive asuitable projecting lug from the seat body (not shown) whereby said seat is secured supported therebetween.

What is claimed is;

In a swing, the combination of a supporting bar, a pair of spaced parallel ears depending from each end of said bar, a sleeve provided with a peripheral lug journaled for rotation between each pair of ears, a pair of suspension members having their upper ends looped around said sleeve so that the peripheral lug of the sleeve intervenes between the terminal of one of said suspension members and the body portion thereof,

and a carrying element connecting the ends of a suspension member of each pair.
