EDWIN L. BUSHNELL, OF POUGHKEEPSIE, NEW YORK.

IMPROVED SPRING-MATTRESS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, EDWIN L, BUSHNELL, of Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Spring Mattresses; and 1 do hereby declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention relates to-spl'ing-beds; and

It consists- First, in constructing the-springs of wire, with eyes or loops, formed by bending or twisting the wire that forms the spring in such a manner that the spring, with its eyes or loops, shall all be made of a single continuous piece of wire, and the eyes or loops be arranged to hold in place the cord or other material used for uniting a series of the springs, to form a bedbottom or mattress; and

It further consists in the uniting a series of springs in a .novel manner, whereby a complete mattress or spring-bed bottom is produced, all as hereiuafteruiorc fully explained.

Figure 1 is a top plan view of a horizontal section on line a; at of fig. 2, and

Figure 2 is an end elevation of a mattress cornplete.

Various attempts have heretofore been made, by myself and others, to construct a spring-bed by uniting, side by side, a series of spiral springs, the springs being connected together by means of cords, wire, or similar devices.

In order to afiord means of attaching the cords, to

the springs, and keep them in their proper positioruit was necessary to provide the springs with eyes or loops, to which the cords were to be'fastcned, but in all cases these eyes or loops were made of separate or detached pieces, and then fastened to the springs. by twisting or bonding their ends around the wire of the spring, or by-soldering them to the spring.

Both of theseplans were expensive, and all failed was bent or doubled in the ordinary handling or turning of it in use.

My present invention has for its object the remedythough I prefer iug of these difiiculties, and, thereby, the producing of a more perfect and useful spring-bed or mattress.

To accomplish these objects, I make a spring with eyes or loops on each end coil, by so bending or twist ing the wire at those points as to form the eyes or loops in the same pieceof wire that constitutes the spring, as represented in fig. 1.

The springs may be made of any suitable form,

truncated cones, united at their smaller ends, as represented in fig. 2, for the reason that it takes less metal, and because, also, the springs are less liable to interlock with each other when the mattress is donbled, rolled, or bent.

In the present case 1- form the eyes a at four points equidistant from each other, in the outer end coil of the spring, at each end thereof, as shown in fig. 1, the eyes being formed by a single twist in the wire, at the required points.

It is immaterial what the form or shape of the eye or loop is, audit may be made by either twisting or bending the wire, the sole requisite being that; it shall i be of such form or shape as to prevent the cord from slipping out of place, and be formed of the same piece that constitutes the spring itself, the function of these eyes or loops being simply as a means of securing the springs to each other and prevent the iastenings from becoming deranged.

Across the upper and lower ends of each row of springs I stretch cords c, and at right angles to the cords 0, but lso across the ends of the springs, I stretch cords f.

By means of these cords 1 tie the adjoining eyes of adjacent springs tightly together, and I also knot the cords c and f together wherever they cross each other at the centers of the springs, as shown in fig. 1.

The top and bottom eyes, on the outside of each of theoutcr springs, I connect by a cord, 0, as shown in fig. 2.

I also connect the outside eyes at the top of all the springs by a cord, cl, as shown in fig. 2, and the corresponding eyes at the bottom of the outside springs by a cord, (1', as shown in fig. 1.

When the springs are thus arranged, they form a light, strong, and elastic spring mattress, which can be used on an ordinary bedstead, without altering or changing the same in any way.

This mattress does not lose-its form by use, nor do the springs become bent out, of shape, as frequently happens in bed-bottoms, as, by my method of connecting the springs, weight cannot beapplied to any one of them singly.

When weight or strain is applied to any one of the series of springs, the spring being closely connected to rnake thorn in the form of two to the adjoining springs, the weight is distributed over several springs.

My principle of construction may be applied, not only to mattresses, but to pillows, cushions, 850., the cords a being shortened in those cases, to give the arlicle a rnnnded form on the edges.

\Vhen my mattress is to be stored or transported, it can be rolled up either crosswise or lengthwise, into a compact and convenient form, and it will, upon being released, immediately resume its original form.

This mattress is cheaper, lighter, and more elastic than the bed-bottoms in which wooden slats are used, and, unlike them, it affords no protection for vermin.

It is obvious that there are many ways in which the cords may be connected, beside the one shown, the

f, as descnbed. EDWIN L. BUSHNELL.
