JOSEPH R. HOOKER, OF CARTHAGE, MISSOURI.

BED-SPRING.

To all whom it may concern:

Be it known that I, JOSEPH R. HOOKER, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented a new and useful Bed-Spring, of which the following is a specification.

This invention relates to bed springs and its object is to provide a novel arrangement of helical springs and means for connecting the same whereby the upper face of the bed spring, which is the one contacted by a mattress, is rendered free of all sharp projections and angles liable to cut into and tear a fabric bearing thereon.

Another object is to provide novel means for tying the various coils together so as to positively prevent displacement thereof in any direction.

Another object is to provide a bed spring in which the number of separate tie devices utilized is reduced to the minimum, the greater portion of said tie devices being formed integral with the coils.

With these and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim.

In the accompanying drawings the pre ferred form of the invention has been shown.

In said drawings: Figure l is a perspective view of a portion of a bed spring constructed in accordance with the present invention. Fig. 2 is a diagrammatical view showing in plan the relative positions of the opposed series of helices and the diagonal and longitudinal braces. I

Referring to the drawings by characters of reference 1 designates the upper frame and 2 the lower frame of the bed spring, the said frames being preferably formed of metal rods bent into proper shape, one being disposed directly above the other. Parallel rows of spring helices are disposed within and between these frames as indicated at 3, and connecting opposite portions of the frame 2 are brace wires 4, each wire extending along the edge portion of one row of helices and being provided adjacent each helix with a substantially U shaped crimp 5. These crimps are extended horizontally and each receives the base of a helix, which base is in the form of a rin 6, formed by bending the lower whirl o the spring in a reverse direction. The terminal of this ring Specification of Letters Patent. Patented June 21, 1910.

is looped around the fold 7 in the lower whirl so as to form an eye 8 and the ring 6 is provided at a point diametrically opposite this eye with a crimp 9 located within the crimp 5 in the adjoining brace wire 4. Those of the springs arranged along one side of the frame 2 have loops 10 extending from the eyes 8 and these loops engage the frame. The intermediate rows of helices however have stems 11 extending from the eyes 8, each stem projecting over the crimp 5 and under the crimp 9 and terminating in a hook 12 which extends under the crimp 5 and thence upwardly in the direction of the frame 1. It will thus be seen that the base portions of all of the helices together with the wires 4 are securely tied together without the necessity of utilizing separate tie devices. All the helices at one side of the center of the bed spring are arranged in the same manner and with their eyes 8 and stems 11 located at the same side. Those at the other side of the longitudinal center are similar in all respects to the helices heretofore described but are oppositely disposed so as to bring the crimps 9 thereof at those sides of the helices nearest the longitudinal center of the bed spring. Two wires 4 are arranged between the two adjoining series of oppositely arranged springs, the crimps 9 of the said springs being disposed within the crimps 5 of the wires, and inasmuch as there are no stems upon the springs which are available for tying said springs together at these points, it is necessary to utilize links 13 having hooked ends 14 which project under the crimps 9 and through the crimps 5, with their terminals projecting upwardly in the direction of the frame 1. In other words, these hooked ends are disposed in the same manner as are the corresponding ends of the stems 11 heretofore described.

The upper frame 1 is provided with cross tie wires 15 and longitudinal tie wires 16, all of said wires being provided at their intersecting points with depressions 17 resting one within the other, the transverse wires 15 being formed at opposite sides of their depressions with upstanding crimps 18, between which rest the hooked upper ends 19 of the helices 3. These hooked ends rest within the depressions 17 in the transverse wires 15 and between the upstanding crimps 18, said ends extending under the longitudinal wires 16 and having their terminals projecting downwardly in the direction of the frame 2. It Will be apparent that by connecting the springs to the tie Wires in this manner it is impossiblefor them to become displaced either in the direction of the Width or of the length of the frame. However, if desired, additional means, such as diagonal braces 20, may be utilized. These braces are located upon the middle portion of the bed bottom as shown in Fig. 2 and have their ends provided with hooks 21, Which are so arranged as to engage both the upper whirls of the springs and the adjoining tie Wires.

It is of course to be understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

WVhat is claimed is A bed spring including a frame, spaced helices each having an unbroken base ring through said U-shaped extension and under 30 the offset portion of the base ring, the hook of the stem engaging one side of the said U- shaped portion of the tie wire.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signatur 5 in the presence of two Witnesses.

JOSEPH R. HOOKER. Witnesses:

ROSETTA HOLBROOK, O. B. STICKNEY.
