PORTABLE SUPPORT.

Specification of Letters Patent.

Patented Sept. 13, 1921.

Application filed June 8, 1920. Serial 1105386334.

To all 'wlwmz't may cancer-mi Be it known that I, HARRYMm'rz, a citizen of the United States of America, and

resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new. and useful Improvements in Portable Supports, of which the following 189 spec1- fication. 1 a

y This invention relates to portable supports and more particularly to that type of support which is capable of being folded for transportation or storage.

The object of the present invention is to provide a foldable support especially designed for sup orting hammocks, which shall be of simp e and durable construction providing a stron and rigid support for a hammock suspen ed therefrom, and which maybe quickly and easily folded into compact form without making necessary the manipulation of screws or bolts.

A preferred embodiment of the invention is illustrated in the accomp nying drawings,

in which,

Figure 1 is a perspective view illustrating the ortable support in its operative position rea y for use;

Fig. 2 is an end elevation on an enlarged scale of the upper portion of said support illustrating a socket member used in the construction of the same; and

Fig. 3 is a side elevation of the shown in Fig. 2. V

1 is a transverse frame member which ma if desired be formed of tubular materia this, however, not being essential to the carrying into effect of the invention. Secured u n opposite ends of said member 1, aresoc et members 2, 3, respectively, said socket members being of like construction and illustrated in detail in Figs. 2 and 3. These socket members comprise portions 4 and 5 which extend substantially at right angles to one another, the member 5 being preferably of tubular construction and arranged to receive the end of the member, 1. For the purpose of connecting the member 1 parts in fixed relation to the member 5. the rivet 6 i or equivalent securing means may be employed. The part 4 of the bracket is bifurcated to form divergent members 7, 8, said members being herein shown as of tubular construction and adapted to have seated within same, the upper ends of

le

9, 10. The

legs

9, 10 are not fixed within t e tubular portions 7, 8, but may be readily with drawn from the same at will. Each of the tubular portions 7, 8, which form sockets for the ends of the legs, as described, is preferably of substantially cylindrical form throughout the main portion of its extent but, as illustrated in Fi 3, the interior wall of said socket adjacent its extremity and on that side adjacent the bar 1, is flared outwardly whereby the diameter of the. socket at its free extremity is increased in a direction substantially parallel to that of the bar 1. As a ready means of securing this result the tubular wall of the. socket may be bent outwardly as shown at 12.

A brace 13 for connecting the leg 10 and the bar 1 is, as herein shown, permanently and pivotally connected to the respective parts at the

points

14 and 15 and similar braces are in like manner connected to the other legs and to the bar. Connecting the legs of each pair at points a substantial.

distance from the socket members 2, are

braces

16, 17, pivoted as at 18, 19 to one leg of each, pair and having hooked

extremities

20, 21, engaging

pins

22, 23, carried by the opposite leg of the respective pairs whereby the

braces

16, 17 may be disengaged from one of the legs of the pair and folded into a position parallel with the other leg thereof.

The curvature of the inner wall of the sockets 8, 9, by bending the tubular Walls thereof as at 12, is such as to permit (after disengagement of the braces 16, 17) of the withdrawal of the upper ends of the legs from their respective sockets, the legs swinging about the points of connection of the braces 13 with the bar 1 and with the leg. By this arrangement of parts the legs may be withdrawn from their sockets and swung in planes parallel to their respective braces 13 until they lie parallel to the member 1. The curvature of the open end of the sockets is such as to prevent binding of the upper end of the leg as it is withdrawn or inserted therein and it is found that this curvature for this purpose must be of a varying radius, the exact form of curve depending in each case upon the dimensions of the several parts.

24 is a lug extending downwardly from the socket member substantially axially of the rod or bar 1, said lug serving for the proper positioning of a canopy member upon the top of the frame.

As shown in Fig. 1, the devlce is in posi tion for use and may have swung from the frame member 1 a hammock or similar structure. When it is desired to fold the frame up for transportation or storage it is merely necessary to disengage the braces 16., 17 by unhooking the same, and then to Withdraw the several legs from their sockets permitting said legs to swing into positions parallel With the bar 1. The sockets 2. may be formed as castings or pressed from sheet metal as desired and it will be readily seen that the device herein disclosed is of simple construction, inexpensive to build and pro vides a substantial and rigid support for the purpose desired, While at the same time permitting of being folded in a simple and expeditious manner Without the use of tools and Without the necessity for removing any detachable parts. I

Having thus described a preferred form ofthe invention together with a mode of use of the same, What I claim and desire to se cure by Letters Patent of the United States is: r

1. In a folding hammock support, in combination, a transverse frame member, a socket member carried thereby and having a substantially circular socket, a leg detachably engaging with the socket in-said socket member, and a brace member pivotally and permanently connected at 'its" opposite extremities to saidframe member-and leg respectively, said socket being constructed and arranged to permit said leg to be Withdrawn therefrom by swinging said leg in a plane parallel to that of the brace.

2. A portable support having in combination a transverse frame member, a socket member secured to said frame member, a second frame member constituting a leg, said leg being normally seated Within a socket in said member, and extending at an angle to said transverse frame member, and a brace pivotally and permanently secured at each end to the transverse frame member and leg respectively, and extending across the angle therebetween, said socket adjacent its receiving end being of increased diametrieal di mension in the plane of said frame members.

3. A folding hammock support having in combination a transverse frame member, a

' socket device fixedly secured to said frame member and providing a plurality of angularly disposed sockets, legs detachably engaging said sockets, braces having their opposite ends pivotally and permanently connected to said transverse member and to the respective leg members, and a brace member extending between said legs, said sockets being constructed and arranged to permit said legs to be withdrawn therefrom by swinging the same in planes substantially parallel to their respective frame connected brace members.

Signed by me at Boston, Massachusetts, this fourteenth day of May, 1920.
