KNOCKDOWN COUCHHAMMOCK.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Original application filed January 10, 1910, Serial No. 537,270. Divided and this application led April 4,

. 1910. Serial No. 553,371.

To all whom it may concern:

Be it known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown in the county of Middlesex and State of Connecticut, have invented an Improvement in Knockdown Couch-Hammocks, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representin@ like parts.

This invention relates to knock-down couch hammocks and in the selected embodiment thereof is of the type disclosed in my Patents No. 574,073, December 29, 1906, and N0. 901,936 October 20, 1908.

This application is a division of my copending application Serial No. 537,270, filed Jan. 10, 1910.

In order that the principle of the invention may be readily understood I have herein represented the same as embodied in a hammock of the Utopia type, wherein*a Figure l is a plan view of a knock down frame particularly intended for use in hammocks of the type shown .in my said patents; Fig. 2 is a longitudinal sectional view of said frame and showing a portion of the hammock body applied thereto; Fig. 3 is a detail in plan of one corner of said frame, a portion of the corner bracket being broken away to show the knock down construction; Fig. 4 `is a detail in elevation looking outwardly, of one corner of an end member and bracket from which the side member has been withdrawn; Fig. 5 is an edge View of one of the corner brackets and parts permanently connected thereto; Fig. 6 is a detail in plan of one corner of a knock down frame, to which is applied a slightly modified form of bracket; Fig. 7 is a view similar to Fig. 6 with a portion of the bracket broken away to show the knock down construction; and Fig. 8 is a sectional detail taken upon the line 8 8 of Fig. 6.

In that ty e of my invention herein illustrated the frame to which the hammock body is applied is provided with cross bars, so that the hammock body may overlie the upper face of the frame and pass beneath said end cross bars to the points of support, the hammock body being preferably continuous. The frame is of a knock down type, and the members thereof are so engaged with each other that a substantially firm and rigid construction is provided and said members retain their assembled condition whether or not the hammock body be applied thereto. That is to say, in the selected embodiment f m invention, the hammock body is not relied upon to hold the members of the frame in assembled position, but the construction of parts isvsuch that upon removal or sufiicient slackening of the hammock body the members of the frame may readily be detached from each other. The hammock frame is not collapsible in the sense that upon removal of the hammock body therefrom or the sufficient slackening thereof, the end members or cross bars tend to separate or drop from the side members of the frame, but is of a knock down construction wherein the end members of the frame are firmly and substantially supported by the side members but may readily be removed therefrom, and preferably without the use of tools, upon removal or sufficient slackening of the hammock body.

Referring more specifically to the drawing, the frame is represented as consisting of side members 1-1 and end members 2 2. To one set of members, and preferably to the end members 2, are secured preferably by nails or screws, corner brackets or members 3--3 having extensions 4 socketed to receive cross rods 5 which may be held by dowel pins as indicated at (5, or otherwise preferably permanently in position. In this manner, each end member 2 with its pair of corner brackets 3 and cross rods 4 makes in effect a single or unitary structure, as most clearly indicated in Figs. 1 and 4.

The side members 1-1 are received byy said end structures of the frame in a suitable manner affording a knockdown construction. One type of this knock down construction is shown in said Figs. 1 to 8 inclusive, wherein I have shown what may be generally termed an interlocking construction of said side and end members. As shown most clearly in Fig. 3, the meeting edges of the members l and 2 are tenoned as indicated at 7, so as to present a substantially stepped or annular construction permitting the ready sliding of the side members l into engagement with the end members 2` and their housing within the brackets 3. This interlocking or other knock down engagement may be of a tenoned, dovetailed, mortised or other formation of sufficient looseness of parts to permit the ready dis-` assembling. The structure illust-rated, however, while permitting the ready disassembling is yet as firm as to hold the frame in true rectangular form without distortion.

It will be observed that the interlocking portions of the end of the members 1 and 2 are of the same thickness, thus giving great strength. l The brackets 3 3 inclose or house the interlocking or interengaging ends of the side and end members and guide the side members -1 as they are slid into position. It will be observed that the side and end members are separated by movement of the parts longitudinally of the frame. It will further be observed that the knock down frame shown in Fig. 1 is composed in effect of but four parts, namely, the two side members 1 1vand the two end structures each composed of an end member 2, the brackets 3 3 securedthereto and the cross bar 5 secured in ,said brackets.`

The knock down frame shown in Fig. 1 may be provided with any suitable seating of cloth, rope or spring formation, such seating bein preferably not attached to but readily etachable from the end members 2 2, so as not Jto interfere with the ready disassembling of the frame. If a flexible wire seating having end springs be provided, the end springs are preferably so connected as to bereadily detachable from the end members 2 2, thereby not interfering with the knock down construction of the frame.L

In Figs. 6, 7 and 8, I have shown a slightly modified form of corner bracket and one wherein the cross rod 8 is positioned beneath the frame instead of as in Fig. 2. For this purpose, each bracket is provided with an extension 9 having a socket or bearing for said rod 8 below the end piece 2. While in the construction shown in Figs. 1 to 5 inclusive the sockets of the brackets 3 completely surround the cross rod 5, in the construction shown in Figs. 6 to 8 the socket is open, but the cross rods are held in position by the hammock body 10. Dowel pins or the like may be employed to prevent lateral displacement of said cross rods. In this type of my invention, the knock down feature is preserved and is of the same character as that previously described.

It will be apparent from the foregoing description that the frame although of a knock down construction is substantially firm and rigid, but that the end members thereof may readily be detached from the side members upon removal or sufficient slackening of the hammock body. Within the scope of my invention, I may provide readily removable pins or the like penetrating the end members of the frame and serving as an additional means to hold the members of the frame in assembled position. M

Having thus described one illustrative embodiment of my invention, I desire it to be understoodthat although specific terms are employed, they are used in a generic and, descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
