HAMIVIOCK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 714,348, dated November 25, 1902- Application filed March 31, 1902. Serial No. 100.810. (No model.)

To all whom it may concern.-

Be it known that I, DAVID FRANKLIN YOUNGBLOOD, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and usefulHammock-Support, of which the following is a specification.

In the construction of hammocks for jails and similar institutions it has been the custom to employ duck or similar fabric' for the bodies and to support the same by straps, several of which are bolted to each end and are secured to the walls of the cells. There are several objections to this construction'. In the first place should the hammock become soiled or infected before it is washed the supporting devices must be removed, and this` consumes considerable time not only in the removal, but also in the replacement. again, the bolts pass directly through the fabric and often tear the same, practically destroying the hammock-body. Another very serious objection is that these leather straps have to bear on metal stirrups, so that they are very soon cutthrough, and the moment one gives way the others on that end usually tear out, thereby destroying the usefulness of the hammock.

The present invention relatesto hammocks of this character; and the object thereof is to improve the supporting devices therefor, said improved devices being so constructed that they may be applied to the hammock-body without making openings therein or otherwise inj urying the fabric, and while being securely fastened to said hammock-body they may readily be removed, if desired, either for the purpose of cleansing the body or substituting a new one, thus overcoming the objections noted above.

The preferred embodiment of the invention is fully illustrated in the accompanying draw- Then,

responding parts in all the iigures of the drawings.

In carrying out the invention as shown, a pair of clamping- sections 10 and 11 are provided,each consisting of shank portions 12 and coacting jaws 13. The jaws are considerably wider than the shank portions, and their inner coacting faces are preferably provided with transverse corrugations 14, saidfaces being disposed in angular relation to the inner faces of the shank portions. The two sections are connected by a clamp-bolt 15, which passes through the shank portions adjacent to the inner ends of the jaws, and one of the sections is provided at its inner end with positioning-lugs 16, arranged to engage over the side edges of the other section, said lugs, however, terminating short of the jaws, so as to leave the adjacent faces and edges of the jaws perfectly free and unobstructed. Both jaws may be provided on their outer faces with strengthening-ribs 17, which are arranged in divergent relation, as shown in Fig. l. The lower section 10 is provided at its rear end with a depending hook 18, that is` located in the same vertical plane as the sections and is arranged to detachably engage in an ear, as 19, secured to the wall 2O of the cell.

In use the end of the hammock (designated by 21) is placed between the coacting jaws, which because of their unobstructed edges and faces permit the fabric to extend beyond the sides of the same. By turning the nut of the bolt the two sectionscan thereupon be clamped tightly upon the body at any point desired. The advantages `of this construction are as follows: In the iirst place, no openings have to be made in lthe ham mock fabric, and the broad bearing-surfaces of the jaws prevent the tearing of the same. To remove the supports, it is only necessary to loosen a single bolt, and said supports may be applied at various points along the edges of the body, so as to be in proper coacting relation to the ears in which the hooks engage. By arranging the inner surfaces of the shanks and jaws in angular relation to each other it will be observed by reference to Figs. 2 and 3 that the outer ends of said jaws will be forced closer together than the inner ends, thus forming a more secure clamp upon the IOO fabric. v Another desirable feature to be noticed is the arrangement of the hook upon the lower section, which thereby relieves the upper section practically of the Weight, or longitudinal strain, said upper section performing only the function of a clamp. Perhaps the most important advantage, however, resides in the fact that after the fabric has stretched, as it will do from use, and the ends become worn it is only necessary to loosen the jaws, fold the worn ends of the fabric, and reclamp the jaws on the folded ends. This serves the double function of taking out the slack and presenting new surfaces to the clamping action of the jaws.

From the foregoing it is thought that the construction,operation,and many advantages of the herein-described invention will loe apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad vantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a ham mock-support, the combination with separate upper and lower sections having shank portions, and jaws which are wider than the shank portions, said jaws being provided in theircoacting faces with transverselydisposed teeth, of a bolt passingr through the shank portions for securing the sections together, spaced separate depending lugs carvried by the shank of the upper section and embracing the lower section, and a depending hook arranged upon one end of the lower section.

2. In ahammock-snpport, the combination with an ear having an oblong slot there through, of a pair of coacting clamp-sections comprising shanks having coacting jaws, means for securing the jaws together, and a depending hook located at one end of one shank, said hook being of substantially the same width as theshank to which itisattached, and fitting in the oblong slot of the ear.

8. In a hammock-support, the combination with an ear having an elongated slot therethrough, of a pair of coacting clamp-sections comprising shanks having coacting jaws, means for securing the jaws together, and a depending hook located at one end of one section, said hook fitting in the oblong slot of the ear.

4. In a hammock-support, the combination with separate coacting sections, each section comprising a shank and a jaw, the jaws being each provided on one side with suitable transverse corrugations, and on the other side with longitudinal strengthening-ribs,and a clamping device engaging the shanks of the sections to fasten them together.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DAVID FRANKLIN YOUNGBLOOD.
