T) T '1 it reed a tine Application filed January 10, 1910. I Serial No. 537,129-

I To all whom it may concern:

Be it known that I, LoUrs I. BERKOWITZ, 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 Hammock-Supports, of which the following is a specification.

This invention relates to a hammock sup port, and its object is to provide an improved collapsible or folding hammock sup port of few parts and simple construction,

which when extended or set up will consti-,

tute a strong and rigid support, and which may be quickly and easily folded one part upon another in substantially parallel relation in compact form for storage or transportation.

In the accompanying drawings which illustrate certain embodiments of the inven tion.Figure 1 is a perspective view of the preferred form of the invention set up; Fig.

2 is a side View of said hammock support shown in Fig; 1', illustrating the manner in which it 1s folded; Fig. 3 is an elevation of one of the pairs of legs and leg brace of the hammock support shown in Figs. 1 and 2, in folded relation Fig. lis a detail view in elevation showing the construction of the top of a pair of legs; Fig. 5 is across sectional view through the top frame member showing in detail the construction of the bracket hereinafter described; Fig. (3 is a side view of a modified form of hanunoch support set up; Fig. 7 is an end view of the hammock support shown in Fig. 6: and Fig. 8 is a bottom view of one end of the harm moc; support shown in Figs. Sand 7 when folded.

Referring to the form of hammock sup port shown in Figs. 1 to 5 inclusive. a repre- The form of securement herein shown consists in'makmg the ends of the legs 5 with a slot 6 into which the plate 6 is set, and

connected by a bolt c sides of the piping b and the plate 5 holds I the plate in place. Each plate 5 is made with an aperture or eye If whichis adapted to pass over the screw aat the end of the top frame. A tubular eyelet '12 passing through the apertures 5 of each pair of legs pivotally holds the legs together, and leaves an aperture or e ve for the entrance of the screw a somewhat larger than the diameter of the screw as best shown in Fig. sh, so that it can be slipped heel on and off the screw. A. thumb nut- (f is provided for each screw (1 to clamp the. plates 7) at the tops of the legs to the top frame a as shown in 1. Each leg'li is also connected with the top frame member a by a diagonal brace c pivoted at .one end to the leg as shown at a. and to the top frame at 0 The detailed construction of the pivotal connection between the braces c and the top frame a is best illustrated in Fig. 5. it bracket (Z secured to the top frame a bva rivet J" is made with two downwardly projecting ears The braces c are provided with holes through which the bolt 0* passes. said holes being sutiicientlv large to permit the braces not only to swing on the bolt in a plane perpendicular to its axis but also to move laterally with relation thereto. Between the braces c is a hollow cylindrical or tubular sleeve a which serves both as a spacer between the ends of the braces c and also as a pivotal. support for the hook /z from which the hannnoclvi ll is suspended. A brace is provided between the. legs of each pair andis piivotallj. connected at one end 'to one leg as snown at and detachahlv sccuredto the other leg at its opposite end by means of a diagonal slot in which a stud on the leg Z) is seated when the device is set up. A thumb screw 0* on the stud e clamps the slotted end of brace c to the leg 5. When the hannnock support is to be collapsed or folded. the screw 6* of each pair of legs is removed and the braces c folded upon leg Z) as shown in'Fig. 3, and the two legs of each pair folded together assist shown in Fig. As already described. the braces 0 are allowed some lateral p y, and will swing toward each other on the bolt 0 when the legs are closed together. The nuts a are then removed and the eyes at the tops of the legs are slipped off from screws a and folded inward upon the topframe member a. Fig. 2 shows one pair of legs completely folded,-and the other pair in the process of being folded. Thus, all the parts of the structure, namely, the top frame, legs and braces may be folded one upon another in approximately parallel relation and in compact form for storage or transportation.

In the form shown in Figs. 6, 7 and 8 the top frame member and the legs, instead of bein made of piping, are made of angle metal." \Vhenthis form is used the brackets 03 are preferably secured on the under side within the channel of the angle metal by bolts d, instead of extending over the top of the bar as shown in Fig l. The pivotal connection between the upper ends of the legs of each pair, in this form of hammock support, and the connection between the tops of each pair of legs and the end of the top frame member, instead of consisting of'two plates, one secured to each leg, consists of the single plate f. The legs are pivoted to the lower (part of the plate f by rivets or bolts f an the extentof the spread of said legs is limited by the inclined edges f of the plate, which engage the side webs of the channel iron legs, the edges f of the end webs of the legs being beveled or inclined to permit the legs to bespread. In the upper part of plate 7 is an aperture or eye f adapted to slip on and off the screw a at the end of the top frame member. In other respects the construction of this form of hammock supportis the same as that illustrated in Figs. 1 to 5 inclusive, and the method of folding and extending the device is the same.

I claim: v 1. A hammock support, comprising a top frame member having a screw projecting from each end, a pair of legs at each end adapted to be folded to ether, a plate secured to the upper end of each leg provided with an aperture adapted to slip over said screws, nut-2; to hold said plates 1n place in said screws, and braces between said top frame member and said legs, pivotally connected thereto, whereby the ends of the legs may be disconnected from the'.top frame .member and all theparts of the structure folded one upon another.
