Toall whom 'it may concern:

Be it known that I, HERMAN L. HoHL- FELD, a citizen of the United States, and a resident of the city of Philadelphia, State of Pennsylvania, have invented a new and useful Adjustable, Collapsible, Folding Hammock-Couch, of which the following is a full, clear, and complete disclosure, reference being bad to the accompanying draw ings, forming a part of this specification.

The main objects of this invention are to provide a couch of simple, cheap, strong and durable construction; to provide a collapsible couch that may be readily'opened and adjusted for use and that may be quickly and conveniently folded into a compact bundie for storage or transportation when not in use; to provide improved means for adjusting or expanding the couch, to keep the fabric of the couch tight; to provide means whereby the fabric of the couch may serve as a support for the couch and also to hold the parts of the couch together When in use; and to provide other improvements aswill appear hereinafter.

In the accompanying drawings, Figure 1 is a fragmentary top plan view showing one end of a couch constructed in accordance with this invention, the opposite end being a duplicate of the end shown; Fig. 2 a fragmentary bottom plan View of the same; Fig.

. 3 a fragmentary longitudinal section on line 33 of Fig. 1; Fig. 4 a fragmentary perspective of one corner of the frame of the couch, the fabric being removed; Fig. 5 a perspective of one of the details of the couch; Fig. 6 a transverse section on lines 6-6 of Fig. 3; Fig. 7 a perspective of the expander of the couch; Fig. 8 a longitudinal section on line 88 of Fig. 7 Fig. 9 a fragmentary longitudinal section through one end of the couch showing the couch in its inverted position; Fig. 10 a fragmentary bot tom plan View of a modified form of this invention and Fig. 11 a transverse section on line 1111 of Fig. 10.

Referring to the drawings, one embodi ment of this invention comprises a couch having a collapsible frame, a fabric cover and an expander connected to the frame, and means connected to the ends of the fabric cover for suspending the couch.

The frame of the couch shown comprises a pair of side bars 1 for forming the sides of the frame and twopairs of crossbars 2-2 adapted to form the ends of the frame, one

sides. respectively ofthe side bar by means of a bolt 5 which passes through apertures 6 provided therefor in the sides of the bracket.

Each bracket 8 is provided with oppo sitely curved substantially semi-circular projections 7 upon the opposite sides respectively of the bracket opening inwardly and outwardly longitudinally of the bar respectively, and which are adapted to engage in annular recesses '8 provided therefor in the cross bars. The annular recesses 8 are longer than the width of the projections 7 and each recessis provided with a pair of rings 9 loosely surrounding the cross bar and entirely filling the space resulting from the difference inwidth between the projec' tion and the corresponding recess in the cross bar. Both of the rings 9 may be placedupon either side of the corresponding projection of the bracket or the rings may be divided and placed one upon each side of the projection, thus allowing for the ad justment of the side bars longitudinally of the cross bars for a distance equal to the combined widths of the rings in each recess.

The cover 10 of the couch is composed of canvas or any other suitable fabric or terial and is preferably made from a single width of fabric, without cutting, by folding and stitching the fabric into the desired shape, thus the cover has a uniform strength throughout its full length. The side edges of the cover are folded longitudinally and stitched to form pockets 11 which are folded outwardly over the top surfaces and outer edges of the side bars and secured to the under surfaces of the side bars by means of staples 12 which extend through the pockets and into the bars, wire rods 13 being re movably placed in the pockets and the staples being driven so as to embrace these rods.

In forming the pockets the edges of the cover are folded around the rods 13 and are then stitched against .the under side of. the cover, the folded portion-of the edges being left wide enough to provide a double thickness of fabric around the outer edges. of the side bars and over the upper surfaces thereof as indicated at 14. The side edges of the ends of the cover are folded under as indicated at 15 and 16,, and the edges are stitched longitudinally to the ends of the cover as at 17 and 18 and the end edges of the cover are folded and stitched to form pockets 19 in which are secured spreaders 20.

The hammock is supported by the usual clue cords 21 which are attached to the Spreaders 20 in the usual manner and which radiate from rings 22 suspended by ropes or other well known or suitable means 23.

For holding the cross bars in place in the brackets of the side bars after the frame has been assembled, the ends of the cover are carried respectively over the upper cross bars and then downwardly between the cross bars and around under the lower cross bars and then upwardly toward their points of support as shown in Fig. 3 of the drawings. By this means the cross bars upon the upper side of the frame inthe outwardly facing curved extensions of the bracket are pressed inwardly by any tension upon the cover and the lower cross bars in the inwardly facing curved extensions of the bracket are pressed outwardly in the same manner and thus the cross bars are held firmly in their seats. It is apparent, however, that when the hammock is released from its supporting ropes and the cover is relieved of its longitudinal tension, the cross bars are readily removable from the brackets of the side bars and thus the hammock frame may be easily and quickly taken apart whereupon the bars of the frame may be placed together and rolled up in the cover, making a compact package for transportation.

For conveniently adjusting the width of the hammock to take up any slackness in the cover, which may arise through the use of the hammock, the frame of the hammock is provided at each end with an expander. This expander consists preferably of two flat bars 25 and 26, of metal or other suitable material, the outer ends of which are pivoted to the side bars by means of the bolts 5 which are also used to hold the brackets in place. The inner ends of these bars are provided with spaced holes 27 of uniform size, and the space between each pair of holes is preferably equal to the width of the one of the rings 9 carried by the cross bars and the two bars of the expander are pivoted together by means of a bolt 28 extending through one of the holes 27 in the inner end of each bar. One bar of the expander is provided upon its inner edge with a recess 29 and the other bar of the expander is provided upon its inner end with a tongue 30 having its end 31 bent to engage in the said recess, the tongue 30 forming a stop to prevent the expander from collapsing outwardly. The expander may obviously be collapsed by moving the inner ends of its bars longitudinally and inwardly of the couch and may be extended by a reverse movement.

When the couch is new, the ringsof the cross bars are adjusted in the outer ends of their recesses so as to come outside the brackets when the frame of the couch is put together and the couch cover and the expander are so proportioned that the expander will be adjusted to its shortest length in which case the adjusting bolt or pivot 28 of the expander will be in the innermost hole of each bar of the expander as shown in Fig. 8. As the hammock is used and the fabric of the cover is stretched, one or more of the rings on the cross bar may be transferred from the outside to the inside of its bracket to permit of the extension of the sides of the frame of the couch and the expander may be adjusted by moving the bolt 28 one or more holes to increase the length of the expander accordingly to take up the slack of the cover.

If preferred, the couch may be inverted as shown in Fig. 9 without changing the construction of the couch in any manner and the cross bars of the frame will be held in position in their brackets in a manner similar to that already described. This figure also shows the use of a mattress 31 in connection with the couch, which rests between the sides and the ends of the frame and upon the cover.

In Figs. 10 and 11, is shown a bottom plan view and a transverse section respectively, of a modified form of this invention in which the cover, instead of being fastened to the side bars by means of staples -is held in place by a lacing 32, which passes through eyelets 33 provided in the edges of the cover in the rear of the pockets 34 containing the rods 35, the pockets 31 being formed as heretofore described.

It is obvious that the expander may be omitted from this construction without injury to the couch, and that other changes in the details of the construction of the couch might be made without departing from the spirit of this invention, or the scope of the appended claims.

Having thus described my invention, I claim and desire to protect by Letters Patent of the United States:
