Letters Patent No.'112085, dated February 21, 1871.

IMPROVEMENT IN SPRING BED-BTTOMS.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom 'it may concern:

Be it known that we, HOWARD SMITH, of Groveton, in the county of Goos and State of N ew Hampshire, and JAMES POTTER, of Portland in the county of Cumberland and State of Maine, have invented a new and useful improved Spring-Bed; and we hereby declare the following to be a full, clear, and exact description thereof, which will enable others to make and use our invention, reference being had to the accompanying drawings forming part of this specification, in which is shown a top view ofthe frame of the bed-bottom and details of other parts, as follows:

A. is a view of the inanner of attaching the spring to the under side ofthe slat.

B is an edge` view ofthe same.

O is a view of a modification of A.

Dis an edge view of another method,

E is a view of the means employed to prevent noise and rattling ot' the springs as they are expanded and contracted.

F shows the spring with its point to enter the cross-bar of the frame.

G H I are views of the mortise in the slats and the sides of the frame.

Our invention relates to certain improvements in attaching the cross-bars to the bed-frame, in attaching the springs to the slats, and in preventing the springs from rattling in spring-beds.

I are the sides ol" the bed-bottom, having the mori tise a to receive the cross-bars b. These cross-bars b are cut in two ways, first, as seen at H, so as to allow the bar to lit into a and second, as shown at c, so as to pass over the sides I after being pressed into c. This will hold the cross-bars without pins or bolts, and will admit of the parts being casilypnt together and as easily taken to pieces and packed for transportation.

The points d ot' the springs I enter the holes e of the c1oss-bars,and can be easily withdrawn when the bed is to bc taken apart.

Te have two methods of connecting the springs with -the slats.

First, as shown at A, where strips of lea-ther are secured to the under side of the slat, and cut soy as to form small loops f, under which the upperI coil oi' the spring F passes, thus securing the said spring and in a measure preventing noise and rattling.

Second, by contining'thc upper coil by metal staples y, as seen at C, with cloth or other soft materials between the spring and the slat, for the same purpose as in A.

To prevent rattling we apply, still further, looped or cnt strips of( leather It to the coils of the s prings, as seen at E.

Thus a method oi holding together a bed-bottom is employed, by whichno bolts or pins are used, and which admits of ready taking apart and compactpacking.

Also, the springs are easily applied and removed, and are prevented from making noise when the bedbottom is pressed down by the weight of the person occupying the same. D shows a method where a .ring of metal, having four hooks, is attached to the under side ofthe slat. These hooks clamp the largest ring of the spiral and thus hold it to the slat.Y

We do not claim independent hooks with daring mouths, in combination with coiled springs, nor fastening the spring by havingone end of it pierce a bed-slat; these are embraced in the patent of D. I. Webster and H. IV. Ladd, September 10, 1867. Neither do Awe claim the combination of two plates, a stud, and a shoulder to hold a spring, nor the same in combination with an additional shoulder. "hese are covered by the patent of. N. .13. White, October 23, 1866. Ours differs from the first-named of these patents in not employing the hooks to secure the coils of the springs; and second, in not having the springs so' formedas to pierce the slats at all. fastening the springs -to the slats is wholly dii'erent from Whites patent, because we attach strips of leather to the under side of the slat and make small slits therein, (see f,) which make a sort of loop, and in under the loops the end of the coil is passed, as shown in lig. A, or as in iig. C; the same means employed to fasten the leather to the slat fasten also the largest coil ot' the wire-spring. The point d ot' the spring F does not enter or pierce the slat at all, but enters the hole c on the cross-bar.

What we claim as our invention, and desire to secure by letters patent, is-

A. spring bed-bottom, as herein described, that is, combining the two parts I I b, the two cross-bars put together `without bolts, and the coiled springs attached to the slats bymeans of the looped and slitted leather pieces f fastened to the slat, as herein set forth.
