Application filed June 17, 1914, Serial No. 845,730. Renewed March 8, 1917. Serial No. 158,459.

To all whom it may concern:-

Be it known that I, HARRY Mm'rz, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in FoldingHammock- Supports, of which the following is a specification.

This invention relates to folding frames of the kind used for hammock supports and for similar purposes, and consists principally of a new and improved structure for joining the top bar with the legs, affording a strong and firm structure with a minimum of parts, and capable 'of being easily set up or knocked down without the manipulation of screws, bolts or other fastening devices.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a perspective view of the frame set up and ready for use;

Fig. 2 is an enlarged end of said frame;- 7

Fig. 3 is a section on line -33 of Fig. 2 showing the position of the legs and their clamping members when said frame is set p;

Fig. 4 is a view similar to Fig. 3, showing the position of the legs and their clamping members when said frame is knocked 1 down; and

Fig: 5 is a horizontal section through one end of the top bar, on line 5 5 of Fig. 3.

The top bar a, and the legs I), may be of ordinary construction, and as herein Y shown consists of tubular iron. The legs are pivotally connected with the top bar byibraces or links 0, each of which is permanently pivoted at one end. to av leg at c, and at the other end at c to the shank a of the hook it. At the proper distance from each end of the top bar a is a collar a, permanently fastened to the top bar by a rivet a (Fig. 2).- The flat shank a extends down from the under side of this collar and terminates in the hook it.

At the top of each leg 6 is a cast' or clamping member (1, riveted to the d l id of the leg, projecting upward and terminating in a semi-cylindrical jaw e, or half sleeve. Each of these half sleeves may be plain or may have a pin 0' on the inner face side view of one then swung apart until the two sleeve sections 0 come together and embrace the end of the to legs are eld in spread position by the cross bars 1 at the bottom. The sleeve is prevented from slippin lengthwise of the top bar a by'the pins e on the inside face of each half sleeve. To take down the frame, the legs 6 are folded together, thereby opening the sleeve, and are then swung parallel to the top bar a on the links 0'.

One of the sleeve sections 6 is made at its outer end with a wall a", which not only closes the end of the sleeve formed by the two sleeve sections 6, 6, when the frame is set up, and conceals the end of the top bar, but also affords additional security to prevent the sleeve from slipping inward along the top bar.

I claim:

A folding frame comprising a, top bar, a-pair of supporting legs pivoted together near the top and sleeve sections at the top of each pair of legs-actuated by the relative movements of said .legs and cooperating to embrace the ends of the top bar to unite the legs and top bar when the frame is set gup, each of said sleeve sections having a pin on its innerv face and each end of the top bar being provided with holes to engage said pin when, the sleeve sections are m closed position, one at least of the sleeve sections of each pair being rovided with bar as shown in Fig. 3. The

an endwall adapted to over ie the end of the top bar.

Signed by me atBoston, Massachusetts, this 15th day of June, 1914.
