WIRE HAMMOCK.`

SPECIFICATION forming part of Letters Patent No. 631,747, dated August 22, 1899. Application led December 15, 1897. Serial No. 661,964. (No model.)

To @ZZ whom it may concern:

Be it known that I, MARSHALL BURNS LLOYD, of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Wire Hammocks, of which the following is a speciiication.

My invention relates to hammocks, and particularly to hammocks made of wire.

The object of the invention is to employ coiled wire fabric in the manufacture of hammocks.

Another object of this invention is to provideawire hamm ook composed of interlocked coils or spirals extending longitudinally of the hammock and having theii` ends gathered together and preferably secured in one bunch or close section at 'each end of the hammock by caps or devices screwed thereon and binding the coils together. Y

A further object of the invention is to provide a novel spreader to distend the hammock and which will be flexible, so that the hammock will conform to the body of the per-y son sitting or lying therein.

The invention consists in a hammock composed of interlocked coils of Wire, the ends of which are gathered or shucked together, or collapsed and suitably fastened, and, further, the invention consists in particular constructions and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

The invention Willfbe more readily understood by reference to the accompanying drawings, forming part of this specification, and in which- -v Figure l is a perspective view showing one end of a hammock embodying my invention.- Fig. 2 is an enlarged longitudinal section of the end fastening or finish with the wires fastened therein. Fig. 3 is a similar view With the Wire removed. Fig. 4 is an enlarged detail of the edge nish of the hammock and the spreader attachment. Fig. 5 is a sectional view thereof, substantially on the line a: .fr of Fig. et. Fig. 6 is a perspective view of a Wire cap or fastening for the ends of the coils, which are rolled or bunched together.

Fig. 7 is a modification of the Wire device shown in Fig. 6.

' Asindicated in the drawings, the hammock is made up of a series of interlocked Wire coils 2 2, which extend longitudinally of the hammock and make up a' Wide and flexible fabric, the edges of which are preferably finished by the employment of one or more sets of coils, making what is commonly known as cords in the edges of the fabric, as shown in Figs. l, 4,5, and 6. At each end of the hammock or piece of fabric of which it is formed the ends of the coils are shucked or collapsed together, and, as illustrated in Figs. l, 2, 3, 6, and 7, are preferably rolled into a solid round bunch. The gathered or collapsed coils may then be secured by a cap or head which may be cast directly thereon, the end of the bunch being inserted into a suitable mold into which the metal is afterward poured; but I prefer to form the cap separately and afterward secure the same upon the bunch, as illustrated in Figs. 2 and 3.

4When the ends of the coils are compressed into a round bunch or end, (see Figs. l and 2,) the surface of the bunch or end will present a Wide thread extending spirally around the bunch and of considerable Width. The cap 5 is cast or otherwise formed With an internal thread 7, corresponding to the natu'- ral thread formed upon the Wire bunch, and said cap 5 may therefore be screwed or turned upon the end or bunch, and When this is done the bunch is so compressed and tightened that the coils are firmly secured in the cap. In fact no other fastening need be employed; but to make the same sure and firm I preferably either use pins extending through the cap andy the bunch of Wires or instead run molten lead 8 into the cap and around the Wires therein, the lead filling all of the unoccupied space, as shown ,in Fig. 2, and effectually locking the Wires against any outward pull. The cap or ferrule 5 is provided with an eye or loop 6, in Which the hammock-rope may be fastened. A modification of this structure is shown in Figs. 6 and 7. AAs there illustrated, I may employ4 a capV or ferrule made of Wire, preferably a spiral coil, fitting bunch of Wires and has its end 17 turned out through the side of the bunch to interlock therewith, and thus dispense with any further fastening for the spiral-wire cap or ferrule. Fig. '7 illustrates a modication comprising a short spiral coilor section 14', adapted to be screwed onto the end of the fabric or vinstead Wound and formed thereon, and the bu-nch or end is additionally secured in the spiral by means of an eyebolt having its stem or shank 18 threaded and extending down through the middle of the bunch, and fastened by a nut 19, which when tightened upon the bolt and against the wires expands the bunch of Wires beneath or outside of the end of the spiral 14 and crowds and expands the Wires Within the spiral. The fastenings shown in Figs. 6 and 7 are light and cheap, but are not as neat and attractive as the cap 5 shown in Fig. 1, and I therefore prefer the latter.

To counteract the tendency to collapse, I preferably extend the hammock at each end by a iiexible spreader, preferably a flat spring or steel strip 9. To hold this strip, I prefer to employ metal clips 10, secured to the edges of the hammock. These clips are 'U -shaped and are provided with raised parts 11, which form the sockets for the Yends of the spring or iiexible strip 9. The clips 10 are secured on the hammock by riveting the same through and through, and to prevent the forming of a sharp kink or bend in the edge of the hammock and at the clip I preferably strengthen the part of the hammock where the `clip is placed by a short piece of spring-wire 12, arranged in the edge coil or cord with the hammock fabric, as shown in Figs. 1, 4, and 5.

It is obvious that my invention admits of various modications in form and construction, and I therefore do not confine the same to the specific constructions herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A wire hammock composed of interlocked coils hunched at the ends, and a spiral arranged upon each end to secure the coils and for attachment to the hammock-ropes, substantially as described.

2. The combination with the gathered ends of the wire coils forming a bunch or roll having a natural thread upon its surface, of the spiral or screw arranged thereon in the thread thereof, and additional means to prevent the drawing of the wires from said spiral or screw, substantially as described.

3. The combination,with the gathered ends of the wire-fabric coils, forming the thread described, lwith the spiral screwed thereon, substantially as described.

. 4. The combination,with the gathered ends of the wire-fabric coils, forming the thread described, of the screw-cap thereon, and said cap being Vfilled to prevent the loosening or turning of the cap on said thread, substantially as described.

5. The combination, of a gathered or rolled coiled wire fabric,with an internally-threaded cap or ferrule screwed thereon, substantially as described.

6. The combination, in a hammock, of the hammock fabric, with a flexible springspreader detachably and transversely secured to said fabric, and held in place bythe resiliencyof the spreader andthe tension of the fabric, substantially as described.

'7. The combination, in adhammock, of the hammock fabric, with a iiexible spreader, and slip-sockets for so securing said spreader to the edges of the hammock that it may be readily detached therefrom to permit the collapsing of the fabric, substantially as described.

8. The wire-hammock fabric, in combination, with the clips on the edges thereof, the wires arranged in said edges, and the spreader having its ends in said clips, substantially as described. l

9. The combination, of the wire fabric-,with the metal clips fastened on the edges thereof and having orfforming sockets, and the resilient spreader lhaving its .ends slipped into said sockets, substantially as described.

10. The combination, of a Wire hammock, with a spreader, and the wires or rods provided in the edges of the hammock at theends of said spreader, substantially as described.

11. The combination, with the hammock, of the bow spring-spreader having its ends held at the edges of the hammock, by the resiliency of the spreader and readily detachable therefrom, whereby the hammock may be collapsed and., if desired, formed into a coil or ring for shipment.

12. The combination, with the wire fabric having the ends of its coils drawn together and suitably fastened, of the metal sockets permanently attached to the edges of the fabric, and the spring-spreaders extending across the fabric and having their ends slipped into said sockets and easily removable therefrom, substantially as described.

13. The combinationin a hammock of the hammock wire fabric Witlia resilient spreader havin-g its ends detachably held at the edges of said fabric and said spreader being held in engagement with the fabric and held at its ends by the resiliencyof the spreader and the tension of the fabric, substantially as described.
