Description

Dec. 24, 1929. R. B. HOSNER BEDSPRING FABRIC Filed March 2; 1926 INVENTOR Hosner BY M H IS ATTORNEY Patented Dec. 24, 1929 UNITED STATES RALPH B. HOSNER, OF SAN FRANCISCO, CALIFORNIA BEDSPRING FABRIC Application filed March 2, 1926. -Serial No. 91,663.
My invention relates to bed bottoms or bed spring fabrics.
One of the objects of my invention is to provide a bed-spring fabric of few and simple parts which may be readily assembled and connected together, and which when connected together, will make a strong, desirable spring fabric having no free ends which might damage the mattress.
Another object of my invention is to provide a bed-spring fabric comprising units which may be connected and arranged in various fashions to provide fabric of differing flexibility.
The invention possesses other objects and features of advantage some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claim.
Referring to the drawings:
Fig. l is a plan view of a portion of my improved bed-spring fabric connected to the spring frame, and showing the zlgzag units in symmetrical arrangement about the connecting springs. Part of the fabric and frame is broken away to reduce the size of the figure.
Fig. 2 is a side elevation of one end of abed spring embodying my fabric.
Fig. 3 is a plan view of a portion of my improved bed-spring fabric connected to the spring frame, and showing another form of the zigzag units symmetrically arranged. Part of the fabric and frame is broken away to reduce the size of the figure.
Fig. 4 is a similar plan view of another form of my zigzag unit construction, the arrangement of the units being that of direct congruity.
In terms of broad inclusion my invention comprises a plurality of similar shaped metal zigzag units arranged transversely of the bed frame and connected together by helical springs also arranged transversely of the frame. The two end units of the fabric are connected to the bed frame ends by suitable coiled springs. The zigzag units may be arranged symmtrically about the connecting springs, that is, in inverse congruity, as shown in Figs. 1 and 3; or in inverse symmetry about the connecting springs, that is, in direct congruity, as shown in Fig. 4. lVith the latter arrangement the bed-spring fabric provides greater flexibility than if otherwise arranged.
My zigzag units or members may be formed in suitable dies or machines, and being of simple shape and all identical, they lend themselves readily to manufacture and are assembled and connected together at low cost.
More specifically my invention embodies a plurality of similarly shaped zigzag members or units preferably formed of a single strip of round wire having an eye 1 turned at each end. The zigzag units are bent to include longitudinal portions 2, and transverse portions 3. The longitudinal portions 2 are not capable of stretching: i. e., they are units is that all longitudinal elasticity is derived solely from the springs 7.
When the zigzag units are placed in symmetrical arrangement about the connecting springs as shown in Fig. 1 alternate gaps 8 are formed between the ends of adjacent units, and alternate end portions 3 are brought side by side, so that when interwoven by the coils 4; the complete fabric offers less flexibility than either of the other two arrangements shown, since deflection from. the horizontal plane of the fabric takes place more readily about transverse axes than about longitudinal axes, and relative movement of adjoining units is more restricted.
In Fig. 4 the units are arranged in inverse symmetry and the transverse portions 13 of the units are staggered and so connected by the coils 14: that relative motion is unrestricted and the fabric offers a maximum flexibility, since deflection may take place with equal case about both longitudinal and transverse axes. r
In Fig. 3 I have shown an alternate form of unit, arranged in direct symmetrical formation. Alternate portions 16 converge so that the gaps 17 formed between adjacent units are of greater length than the transverse portions 18.
I claim:
'Abed-spring fabric comprising a plural ity of zigzag units having longitudinal and transverse portions and extending transversely of the fabric, and coils extending transversely of the fabric and interwoven about the transverse portions of adjacent units.
In testimony whereof, I have hereunto set my hand.
RALPH B. HOSNER.
