WILLIAM GRAY, OF SPRINGFIELD, MISSOURI.

HAMMOCK.

Specification of Letters Patent.

Patented 1\l'0v.` 19, 1907.

Application filed May 6. 1907. Serial No. 372.276.

To all 'whom it may concern:

Be it known that I, WiLLIAM GRAY, a citizen of the United States, residing at Springlield, in the county of Greene and State of Missouri, have invented new and useful Improvements in Hammocks, of which the following is a specilication.

The invention relates to an improvement in sup porters for use with hammocks, cradles,

, which the hammocks will be resiliently supported and permitted all desirable movements.

The invention will be described in the following speciiication, reference being had particularly to the accompanying drawings, in which:-

Figure 1 is a perspective view illustrating the construction and use 0i my improved supporter, Fig. 2 is an enlarged sectional view showing the construction of the swinging hanger with the upper bar of the frame, Fig. 3 is a sectional view partly in elevation illustrating the means for securing the side frame bars in adjusted relation, Fig. 4.is an elevation, partly insection, of the heads of the swinging bar to which the hammock is attached, Fig. 5 is a detail perspective of the supporting plate for use with the head.

Referring particularly to the accompanying drawings, my improved supporting frame comprises feet 1, a lower cross bar 2, side hars 3, and an upper cross bar 4, from which latter depends the hanger bars 5.

The respective parts of the supporting frame are made up of tubing of ordinary construction connected by couplings to provide the desired arrangement.

The feet 1, which are identical, comprise short lengths of piping 6 each provided at their outer terminals with elbow couplings 7, and connected at their inner terminals by a tee coupling 8. The free ends of the elbow coupling 7 form a relatively broad bearing to rest upon the supporting surface. One end of the tee coupling 8 is engaged by the head of the second tee coupling 9, the horizontally disposed member of which receives one end of the rod 11 forming one of the two rods constituting the lower cross bar 2. The adjacent terminals ofthe rods 11 are connected by a coupling 12, of any desired or preferred type. The side bars 3 ofthe frame comprise a suitable length of piping 13 and an appropriate length of rod 14, the latter being arranged for telescoping in the pipe section 13 and being secured therein by a clamping couplin 15, which coupling is formed in its relative y-inner surface with a threaded portion 16 inclining longitudinally of the coupling and adapted to engage threaded sections 17 of the pipe section 13. The threaded sections 17 are formed sufficiently flexible to be operated by the clamp coupling by longitudinally slitting the end of the pipe section 13, as clearly shown in Fig. 3. By this construction the rod section 14 may be adjusted longitudinally of the ipe section 13 as desired, the clamp coup ing operating to hold the parts in the adjusted position.

The upper ends of the rod section 14'of the side bars are provided with tee couplings 19, which in turn are connected to the upper cross-bar 4, the medium of connection belng a sleeve 20 equal in exterior diameter to the interior diameter of the cross bar 4 and the elbow coupling 19, the ends of the sleeve being threaded for engagement with the interior surface of the respective coupling and cross bar and being of such length that when in place a plain surface 21 is provided between the ends of the adjacent coupling and cross bar. A bearing sleeve 22 is revolubly supported on the plain portion 21 of the connector sleeve 20, the ends of the bearing sleeve being adapted to bear against the respective ends of the elbow coupling and cross har, so that said sleeve 22 is permitted a free revolution against the connector sleeve 20 but is held against longitudinal movement thereon. The bearing sleeve 22 is formed with an oil'set coupling 23 interiorly threaded for the reception of a head 24 of a rod 25 forming part of the hanger 5. The lower end of the rod 25 is adapted to fit within a pipe section 26, being secured therein by a nut 27 threaded on the end of the pipe section and formed with an interior annular rib 2S to provide an upper bearing or limiting rib for a coil spring 29 .arranged Within the pipe'section 26 and encircling the rod, the lower end of the spring being fixed relative to the rod by a cross pin 30, all as clearly shown in Fig. 2.

' pensive The lower end of the sleeve section 26 is provided with a tee coupling 31 to the cross connection of which are attached couplings 32. The free ends of the .elbow couplings are connected to a supporting plate 33 through the medium of screw bolts 34 passed through openings 35 in the supporting plate and entering the couplings. he supportingplate is of approximatel Z-form having the lower o'set section 36 a ted for the reception of the hammock, ora e, or other recelver 37.

`'Ihrough the medium of the various cou lings described the respective parts of t e supporting frame may be readily disconnected for acking into close quarters when it is desire and this constitutes the essential feature of the present invention. Furthermore, the materials employed are such as are ordinarily constructed for other purposes, so that the article produced by my in-A vention is of essential simplicity and inem in manufacture.

It is, of course, to supporting plate 33 is to be specially constructed Wit 1 specific regard to the article to be supported. In the event of a hammock .being supported 'by the frame, the projecting plate 36 may be in the form of a hook to receive the hammock rings.

The free movement of the bearing sleeve 22 permits the swinging movement of'the hangers 5 of the uppercross'bar, vWhile the spring connection between the rod 25 and pipe section 26 provides for longitudinal' movement of these parts with relation to each other under the weight supported in the hammock.

The length of the section 6 of the feet is referably such toprovide a stable support or the frame, while the length of the cross bars 2 and 4 are to be limited only by the purpose for which the frame is designed.

The upper cross bar 4 of the frame may be Yand t .vious from Fig. 3 o the drawings.

1. A hammock supporter com rising adjustable side bars, an up er cross ar removabl connected to the s1 e bars, hangersrevolu l supported on the lpper cross bar, said hangers comprising sli ably connected sections, andl a" spring resisting independent movement of the sections in opposing directions.

2. A hammock supporter comprising side bars including independent sections, means for clamping said sections in adjusted posihavin threaded connection with each side bar an with the adjacent ends of the upper cross bar, and hangers revolubly supported on the sleeve, said' hangers comprising slidably connected sections, and a spring resisting movement of the respective sections in opposing directions.

3. A hammock supporter comprising side bars including independent sections, means for clamping said sections in adjusted posian upper cross bar, a sleeve havin threaded connection with each side bar an with the adjacent ends of the upper cross bar, hangers revol'ubly supported on the sleeve, said hangers comprising slidably conl nected sections, a spring resisting movement of the res ctive sections `in opposing directions, an hammock supporting plates carried by the hangers.'

In testimony whereof, I affix my signature 1n presence of two witnesses.
