$.PECIFICATION forming part of Letters Patent No. 542,170, dated July 2, 1895.

Application filed February 15, 1895. Serial No. 538,595. (No model.)

To all whom it may concern:

Be it known that I, AMBROSE L. NORTON, a citizen of the United States, residing at Attica, county of Wyoming, and State of New York, have made certain Improvements in Spring-Beds, of which the following is a specification.

Myinvention relates to spriug-bedsiu which are employed the ordinary hour-glass springs retained in place at top and bottom by a seriesof strips of tempered galvanized steel wire, each strip consisting, preferably, of two parallelstrands connected together by an intermediate wire netting interwoven therewith.

One object of my invention is to provide a method of fastening the springs to the strips so that each alternate spring will exert a constant lateral tension upon the whole frame directly opposite to that exerted by the adjoining springs, whereby swaying or other movement in any direction except vertically is obviated. I

Another object of my invention is to provide a manner of fastening the springs to the strips that will prevent the latter from slipping or moving upon'one another, thus retaining them securely in place.

A still further object of my invention is to provide a border for the bed constructed in the same manner as the connecting-strips and so attached to said strips and springs as to leave no sharp corners or points to catch or tear the ticking of the bed.

Still another object is to provide a manner of securing the strips to each other and to the border without the use of additional fastening devices.

Another object is to provide a manner of fastening the springs to the strips that will prevent the springs from uncoiling and thus losing their tension.

These objects I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of one end of a spring-bed constructed in accordance with my invention. Figs. 2 and 3 are detail plan views of the top and bottom coils, respectively, of one of the springs, showing the manner of attachment to the connecting-strips.

Fig.4 is a detail side elevation showing the staggered position assumed by the springs before being fastened to the strips at their lower ends.

In the said drawings, A A denote the springs, preferably of the ordinary hour-glass shape, and retained in place at top and bottom by the longitudinal and transverse strips B B. These strips are shown as made up of two parallel twisted strands of tempered galvanized steel wire connected together by an intermediate wire-netting b, as shown. These strips are preferably previously manufactured in any suitable manner in an endless strip, from which the lengths are cut suitable to form the connecting-strips. The manner of connecting the top and bottom coils of the springs A to these strips at their crossing points is clearly shown in Figs. 2 and 3. As shown, thefree ends of the springs are bent into the books a, the top and bottom hooks of each spring being located diametrically opposite to each other. The top coil of each spring is shown in Fig. 2 as having its end a hooked over one of the strands of the transverse strip B, passing from thence over the other strand of said strip, under the longitudinal strip B, over the transverse strip B again, and, finally, under strip B, continuing from thence downward into the narrowed portion of the hour-glass construction of the spring. The bottom of said spring is fastened to its strips in the reverse manner, as shown in Fig. 3, the hook at engaging with one strand of the transverse strip B, thence under the other strand of said strip, over strip B, under strip B again, over strip B,

and from thence continuing up into the narrow part of the spring. It will be noticed that the two hooks a are diametrically opposite, thus fastening the ends of the spring in such manner that the liability to unhook from the strips is greatly lessened and the spring prevented from uncoiling, thereby retaining its tension.

I have shown in Figs, 2 and 3 the strips B B in solid lines for convenience in illustrating, but it will be understood that these strips are constructed in the same manner as that shown in Fig. 1. I

The interwinding of the top and bottom coils of the springs A with the strips B B cffectually binds the latter in place with respect to each other and prevents any slipping of the same.

I have shown in Fig. 4 of the drawings a side elevation of a series of the springs A, which will illustrate the positions they assume before being fastened to the bottom strips of the bed. It will readily be seen from this that when they are drawn into a vertical position and fastened at their hottoms each spring will exert a lateral strain in the direction it is shown staggered, so that they will counteract each other, thereby preventing any swaying or other lateral movement of the bed.

Passing around the outer edge of the bed at top and bottom is the border 0, which is formed of the same material as the strips 13 B. At each corner this border is passed under and over the top coil of the corner spring. The free ends of the strips 13 B are bent into the hooks c, which engage with the inner strand of the border 0 and retain it firmly in position.

It will be understood that Fig. 1 illustrates the top frame of the bed and that the bottom frame is formed in a corresponding manner.

I do not wish to limit myself to the exact construction of strips and border shown, as this may be somewhat varied, provided they consist of an open-work construction of tempered galvanized steel wire.

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

1. A spring bed consisting of a series of coiled springs connected together at their tops and bottoms by a series of longitudinal and transverse openwork tempered steel strips having their ends bent into hooks to engage the outside strips'runniug at right angles thereto, substantially as described.

2. In a spring bed, the combination with a series of coiled springs having their top and bottom ends bent into hooks located diametrically opposite to each other, of a series of openwork tempered steel strips with which said hooks engage, said strips being also intermeshed with the top and bottom coils of the springs, substantially as described.

3. In a spring bed, the combination with a series of coiled springs, and a series of longitudinal and transverse strips With which said springs engage, said strips being formed of openwork tempered steel, of a border for the bed, also formed of openwork tempered steel, and engaged with the ends of the strips by hooks formed on said ends of the latter, substantially as described.

4. The combination with a series of connecting strips, of a series of coiled springs, each alternate spring being so connected with said strips as to exert aconstant tension upon thewhole framework of the bed in a direction opposite to that exerted by the adjoining springs, as set forth.
