J'Or'rN DECYAMP, .OF OINOINNA'TLOHIO.

Letters Patent No. 95,329, dated September 28, 1869.

IMPROVED- BBD-BOTTOM.

The Schedule referred to in thse Letters Patent and making 'part ofthe same pgw--L- To whom, it may concern; y

Be it known that I, JOHN DEGAMP, of .Cincinnath Hamilton county, Ohio, have invented 'a new and useful Bed-Bottom; and I hereby declare the-following to be a'full, clear, and 'exact description thereof, reference being had to the accompanying drawings, mak'-4 ing part of this specification.

My invention relates to the class of bed-bottoms in which a series of wooden slats are supported upon spiralsprings,and consists in va simple and effective mode ot'attaching the springs and. slats, without the yuse of any wovenor fibrous fabric, such as webbing,

straps, cords, andthe like, which are objectionable because of their liability to harbor'verminkbesides being Very` destructible andcapable of attachment in the manufactory only, thus making it impossible to separate the parts for package, cleansing, or transl portatiomascan be done with my arrangement. l

My invention also dispenses with the use of any lat- 4eral strap or brace, whether of wood, metal, or other material. v

' The construction being also such as to bel capable of being quickly taken to pieces and put together again by any person of ordinary intelligence, or of being readily reduced in size to fit a'ny particular bedstead.

Figure 1 is a perspective view of a bed-bottom embodying my invention.

Figure 2 is a transverse section of the same.

Figure 3 is a section on an enlarged scale through one of'the springs, with its accompanying nut.

Figure 4 is a perspective View ofthe nut.

A .A A are three bearing-rails, whose ends are in-` tended to rest in rebates 4in the side rails of the bed- Resting upon, and attached to these rails areas many series of 'spiral springs, B", -of the customary truncated conical form, except that their upper extremities C pass vertically through apertures din the slats D, and are screw-threaded to receive nuts, E, somewhat concave or dished, or with aprojecting margin, c, on their under sides, and wings e on the upper sides, with which to turn thenut by hand.,

The spring has its base or large diameter to' the rail, and supports the slat upon the upper coil.

lThe nuts Eenable all the parts ofthe bottom to bei` in a few minutes united in `one compact.. and s tanch, yet elastic whole, without the use of any tool whatever, or any mechanical skill and the flat and rounded upper contour of the nut prevents Wear o f the mat tress, while its sharp and salient lower margin gives' it a firm'and stable attachment to the Slat. f

The nuts are preferably of metal, but maybe 'of hard wood, or its equivalent, and may, if desired, enter recesses or countersinks in the tops of the slats. The number of rails, slats, and series of springs may be greater or less, as may be desired.'

It is intendedthat thesprings'n this form'of bottom shall be of suicient stiffness to supersede theI necessity offwebbing or A other lateral stays. About No. 7 wire makes a good spring'for this purpose.

i In order to put this bottom together, it is merely necessary to pass the upper ends of the springs through the apertures d, and fasten the same by the nuts E, an operation that can be perfolmed by the thumb and fin er.

hould the bottom be too large for the bedstead, it

can be easily fitted to it without 'any detriment, by

simply shortening off the rails or slats, as the case may be.

For transportation or removal, the bottom may be in'a few minutes taken apart, without any tool Whatever, and put in one or more 'very compact parcels.

This bottom is equally elastic in every part,-and laffords no harbor whatever for vermin, nor is it liable to getout of order by use;

I claim herein as new and of my invention- The combination of the slats A D, the spring B, screw O, and dish-formed or concave lnut E c, provided with wings e", all constructed and arranged as and for the purpose set forth.

In testimony of which invention, I hereunto set myhand.

W itnesses:'
