BED-SPRING FABRIC.

Specification of Letters Patent.

Patented May 29, 1917.

Application filed July 22, 1915, Serial No. 41,292. Renewed October 26, 1916. Serial No. 127,963.

To all whom it may concern:

Be it known that I, GARY B. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Bed-Spring Fabric, of which the following is a specification.

The present invention appertains to bed spring fabric, and is particularly an improvement over the bed-spring fabric disclosed in my Patent No. 1,149,793 issued August 10, 1915.

The primary object of the invention is the provision of a novel bed-spring fabric which will not sag at the center as usual or tend to roll the occupant or occupants to the center.

It is the object of the invention to provide a bed-spring fabric of the general character disclosed in the said patent, which is capable of inexpensive manufacture, and which is of such construction that the fabric may yield at various portions thereof without materially affecting the other'portions. This latter feature is of decided advantage inasmuch as the occupancy of one side of a bed utilizing the present spring fabric, will not tend to displace or distort the other side of the fabric, and consequently two persons reclining upon the bed will not act tothe discomfiture of either.

The foregoing advantages are accomplished by the provision at various points throughout the fabric, of a plurality of cross chain links between the respective longitudinal strands, allowing the longitudinal strands to separate or yield when they are depressed at one point of the bed, without materially displacing the strands at the other portions of the fabric.

Another object of the invention is the provision of novel means for attaching together the longitudinal strands, for connection with the end springs of the fabric, without the liability of the strands becoming detached.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter clescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan'view of the improved bed-spring fabric, portions thereof being broken away.

Fig. 2 is a cross section taken on the line 22 of Fig. 1.

In carrying out the invention, the improved bed-spring fabric embodies a plurality of spaced parallel longitudinal strands l, of which there are a suitable number according to the Width of fabric desired, and each of the strands is preferably formed from a plurality of wires twisted together in the form of coils, whereby the strands will be slightly elastic to increase the flexibility of the fabric.

The strands 1 are connected at spaced 1ongitudinal points by a suitable number of cross chains 2 which are arranged transversely or at right angles with the strands 1. These cross chains generally resemble the cross chains disclosed in the said patent, and may be readily applied to or assembled with the strands 1 according to the process disclosed in my co-pending application Serial No. 851,969 filed July 20, 191 1.

p The terminals of the strands 1 are fastened together in pairs, that is, the terminals of each pair of strands 1 are fastened together by intertwisting them, as at 3, and the terminals of the strands are twisted together in the direction opposite to the direction in which the wires are twisted. By

doing this, the ends of the strands are so securely fastened together that they will not untwlst or become detached. The ends of the strands being twisted together provide V-shaped crotches or loops 4 for the engagement of the hooks of the end springs (not shown) usually employed in bed-spring fabrics for attaching the fabric to the frame of the bed.

If there is a single strand 1 at one or both sides of the fabric, the terminals thereof may be bent back to form eyes or loops 5 for the engagement of the end springs, the terminals of said strand being wound or wrapped around itself, as at 6.

Each of the cross chains 2 comprises a series of doubled wire links 7 having their ends bent back to form hooks 8 engaging the bends or bights of the adjacent or companion links and also embracing the respective strands 1. The links 7 are preferably disposed above or upon the strands 1 with the hooks 8 engaging downwardly under or around the strands, and with the bends or bights of the links abutting against the respective strands and held thereagainst by the hooks. The bends of the links are disposed between the strands and the bends of the hooks, and the hooks being bent around and embracing the strands will securely fasten the cross chains to the longitudinal strands whereby they will remain properly assembled.

Throughout the greater portion of the area of the fabric, there are but single cross tie links 7 between each pair of strands 1, but scattered in any suitable arrangement throughout the area of the fabric, there are pairs of links 7 between the respective strands 1, as at 10. These doubled pairs of links 7 are preferably disposed in a staggered arrangement, whereby the utility of the cross chains 2 to jointly hold the strands l in proper spaced relation will not be de stroyed, and said doubled pairs of links 7 will be doubled, or the joint therebetween will be broken, so that said l-inks break and swing downwardly in V-shape, as clearly seen in Fig. 2. When the strands 1 separate, due to the fact that the fabric is bulged downward by the weight of a person thereon, the folded or doubled links 7 can swing apart toward a straight line position for allowing such action of the strands, and the doubled links at one portion of the fabric permit the strands at said portion to yield and separate without displacing or distorting the remainder of the fabric to any appreciable or objectionable extent.

It will therefore be obvious that with the present construction of bed spring fabric, the desired utility of the cross chains in normally holding the strands in proper spaced relation is not lost, and furthermore the fabric in being capable of yielding at various portions thereof without affecting the others, will render the fabric particu larly desirable for use in double beds, so that each of the occupants may rest in comfort upon the spring fabric.

It may be stated that the links 7 at one side of the fabric have their bends or bights bent into hooks 11 embracing the respective side strand 1, so that said links are hooked to two of the strands 1 instead of one only as the other links. This provides means for attaching the respective ends of the chains 2 to the strand 1 at one side of the fabric.

The strands 1 may be cut from long lengths, and during the manufacture of the fabric, several bed-spring fabrics may be made simultaneously, the strands 1 being cut or torn apart when the twists 3 are made.

The strands being independent and having their ends attached as indicated will cause the strains to be transmitted longitudinally of the strands, and this avoids the distortion of the fabric. This is of advantage over the continuous strands disclosed in my Patent No. 1,149,793, because of the fact that the strands in the said patent are arranged in somewhat a zigzag manner which tends to destroy to some extent the rectangular formation of the fabric due to the strains imposed.

The present fabric prevents sagging at the center and also obviates the tendency to roll the occupant or occupants to the center. Furthermore, the strands may be brought closer together or moved farther apart to accommodate the various members or spacing of the end springs used to con nect the ends of the strands with the bedframe.

Having thus described the invention, what is claimed as new is:

1. In a bedspring fabric, strands, cross links connecting them, there being throughout the greater portion of the fabric single links between each pair of strands, and at various points throughout the fabric a pair of doubled links between the respective pair of strands.

2. In a bed-spring fabric, strands, and cross chains comprising links engaged with the strands, there being throughout the greater portion of the fabric single links between each pair of strands, and at various points throughout the fabric a pair of doubled links between the respective pair of strands.

3. In a bed-spring fabric, strands, and cross chains comprising links engaged with the strands, there being throughout the greater portion of the fabric single links between each pair of strands, and said chains having at various points throughout the fabric yieldable portions between the respective pair of strands.

4. In. a bed-spring, strands, cross chains, each embodying a series of doubled wire links having their ends bent into hooks engaging the bights of the companion links and embracing the respective strands, there being throughout a greater portion of the fabric a single link between each pair of strands, and at various points throughout the fabric a pair of doubled links between the respective pair of strands.

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

GARY B. SMITH.
