Description

S. RUSNAK.
BED FABRIC.
APPLICATION FILED MAR.31,1913v Patented Nov. 18, 1913.
SAMUEL RUSNAK, OF CHICAGO, ILLINOIS.
BED FABRIC.
Specification of Letters Patent.
Application filed March 31, 1913.
Patented Nov. 18, 1913. Serial No. 757,786.
To all cell 0m 1' It may concern Be it known that I, Stunner. lusnrin, a citizen of the United States, residing at the city of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Bed Fabrics, of which the following is a specification.
My invention relates to fabrics which are used on beds and couches to support the mattress, upholstering or other covering. The so-called fabrics consist of a multiplicity of interlacing thin and comparatively broad strips of flexible metal normally spaced from each. other. They are usually suspended from helical springs attached to the ends of the longitudinal strips. The cross strips in a properly designed fabric should be so eonstructcd to engage the longitudinal strips and prevent them from spreading apart bcyond the normal and fixed distance. The longitudinal strips have a certain amount of vertical play as the helicals by which they are supported at the. ends are extended, but, on the other hand, it is desirable that the fabric should be susceptible of being placed or arranged so that the degree of rigidity may be varied or decreased.
By the application of the principles of my invention, I am able to so interlock the cross or stay pieces and the longitudinal slots, that the latter are positively spaced through and across the stay strip and different degrees of flexibility may be secured according to the manner in which the fabric is placed in the frame or support.
The principles of my invention are illustrated in the drawings, in which Figure 1 shows a top view of a portion of a bed fabric; Fig. 2 is an enlarged detail showing a top view of the same; Fig. 3 is a similar view showing a bottom view thereof; Fig. 4 is a side view of oneof the cross strips inverted; and Fig. 5 is a perspective of an interlocking member.
Further describing my invention with reference to the drawings: 1 is a side rail, and 2 an end piece of a frame upon which my improved fabric is represented as being mounted.
33 are helical springs attached at one end to the cross pieces and having the other end attache! to the longitudinal strips 4. The cross stay or strips 5 are fUl'HlCd as shown in Fig having portions (3, (i off-set on one side and similar portions 7, 7 off-set on the other side or face. The off-sets on one side should be the length corresponding to the width of the loi'igitudinal strips, while the offsets on the other side should be of a length corresponding to the space by which the longitudinal strips are to be separated from each other. A locking member 8, consists of a piece of metal having a central opening 9. Said member may be formed as shown by cutting and punching from a flat piece of metal, or it maybe made from a suitable section of wire or rod. One dimension of said opening should be slightly larger than the width of the cross or stay strips and the other dimension should be such as to permit the locking member to be placed over one of the off-sets as 7, and rest upon the underside of the corresponding offsets 6, as indicated in Fig. 4. The longitudinal strips may then be carried through the open space 7 on the underside of the oif-set 7, in which position they will be held in placcby the locking member so that trans verse movement will be prevented while free movement in a longitudinal direction is permitted. The ends of the cross or stay strips should be secured to the outer longitudinal strips by rivets 10, or by any other suitable mechanical means. The fabric described should be suspended upon the helical springs with-reference to the amount of flexibility desired. Should it be desired to make a highly elastic fabric, it should be mounted in the position shown in Figs. 1 and 2. Downward pressure. whereby the stay strips are bent downward in this position, tends to give free movement of the longitudinal strips through their inter-sectional engagement with the stay strips. On the other hand, when mounted as shown in Fig. 3, a similar downward movement tends to bind the longitudi-' nal strips in relation to the stay strips and gives a frictional engagement, whereby their movement will be resisted, and the extension of the. helical springs by which they are supp rted will be reduced.
I claim:
1. In a bed fabric the combination of Iongitudinal strips, stay pieces placed transversely thereof and provided with off-sets, and locking members adapted to fit over the off-sets and form inclosed spaces between said members and the underside of said offsets within which said longitudinal strips are slidaloh received.
2. Tn a bed fabric the combination of Iongitu'dinal strips, stay pieces placed transversely thereof and provided with otfasets, and flat locking members adapted to fit over the off-sets and form inclosed spaces between said members and the underside of said off-sets within which said longitudinal strips are slidably received.
3. In a bed fabric the combination of a multiplicity of longitudinal strips, elastic end supporting means for said strips, stay' strips placed transversely of the longitudinal strips and provided with off-sets correspending in number to the longitudinal strips crossed thereby, separate locking members adapted to fit over the off-sets and form inclosed spaces between said members and the underside of said ofl"-sets wherein said longitudinal strips are slidably received, and means for attaching the ends of the transverse strips to the outermost longitudinal strips.
In witness whereof, I have hereunto sub scribed my name, this 26th day of March 1918, in the presence of two subscribing witnesses.
