EDWIN Il. BUSHNELL, OF POUGHKEEPSIE, NEW YORK.

IMPROVED SPRING-MATTRESS.

Specification forming part of Letters Patent No. 95.984, dated October 19, 1869.

To all whom 'it 'may concern:

Be it known that I, EDWIN L. BUsHNELL, of Poughkeepsie, in the county ot' Dutchess and State of New York, have invented certain new and useful Improvements iu Spring-Mattresses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accom panying drawings, making part of this specification, and to the letters ot' reference marked thereon, like letters indicating like parts wherever they occur.

'Iof enable others skilled in the ait to construct and use my invention, I will proceed to describe it.

My invention relates to a spring-mattress; and it consists in a series of coiled or helical springs provided with eyes,aud connected together by cords `in such a manner as to hold them in theirproperrelative positious,the whole forming a light and elastic mattress, answering all the purposes of the ordinary bed-bottom, with the advantage that it can be rolled up into-a compact form for storage or trans-` portation. 'f' In the drawings, Figure 1V is a horizontal section through my mattress, taken on the line :v a' of Fig. 2; and Fig. 2 is an end view ofthe mattress.

A A are the springs, made in any of the common forms, and provided at each end with four small eyes, a, made by twisting thewireat thjose poiuts,asshowninFig.1. Thescsprings I arrange close together in rows, so as to form the` outline of the required mattress, and so that the eyes of each spring shall be in contact with the eyes of adjoining springs.

Across the top and bottom of each row of springs I place cords c, and at right angles to the cords c, but also on top and bottom ot springs, place cords f. By means of these cords I fasten all the adjoining eyes of adjacent springs securely together, and I also knot the cords together where they cross each other at the centers of the springs, as shown in Fig.

1. rlhe top and bottom eyes ou the outer side ofthe outside springs I connect by cords e, as shown in Fig. 2. When the springs arevtllus arranged they form a light, strong,and elastic spring-mattress, which can be used in any,ordinary bedstead without changing or altering the same in any way.

This mattress does not loseitsform by use,uor do thesprings become bentout of shape,as frequently happens in bed bottoms, as by my method ot' connecting springs weight cannot be applied to them singly. When strain or weight is applied to any one of the series of springs, the cords c j', communicating with the adjoining springs, distribute the strain over several of the series.

My principle of construction may be applied not only to mattresses, but to pillows, cushions, &c., the cords e being shortened iu those cases to give the articles a rounded form on the edges.

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

This mattress is cheaper, iighter, and more elastic than those in which wooden slats are used, and, unlike them, affords no protection for vermin. I

It isv obvious that there are many ways ot' connecting the springs by cold besides that s'hown in the drawings, the manner shown being, however, considered the best.

Having thus described my invention, what I claim is f:

l. The spring A, having the eyes a formed thereon at each end, as set forth.

2. A spring-mattress consisting ot' a series of spriugs,-A, with eyes e, united by cords c and j', as described.
