BED-BOTTOM AND MEANS FOR TIGHTENING AND SUPPORTING THE SAME.

SPECIFICATION forming part of Letters Patent No. 404,722, dated June 4, 1889. Application filed September 5, 1888. Serial No. 284,679. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH E. MOORE, a citizen of the United States, residing at WVarwick, in the county of Franklin and State of Massachusetts, have invented certain new and use ful Improvements in Bed Bottoms, Chair Seats, Backs, &c., and Means of Tightening and Supporting the Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in bottoms for chairs and in bottoms for beds.

The invention relates also to an improvement in means for tightening and sustaining such bottoms.

In the drawings illustrating my invention, Figure 1 is a plan or bottom view showing my improvements as applied to a bed-bottom. Fig. 2 is a transverse vertical sect-ion of the same. Fig. 3 isa plan showing the arrangement of the tightening device applied in circular form to a chair. Fig. 4 is a section centrally cut through circular bottom. (See Fig.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, A A represent two of the rails of a frame, and B B two other rails of the same.

0 O is the bottom, formed of two pieces of material, the one lapping over the other.

a a are reeds run in hems in the end of the fabric composing the bottom, the pieces of which are sufficiently long to admit of doubling the same over and under the rails of the frame for the bottom.

In order to secure the bottom firmly to place on its frame, I employ hooks D, provided with screw-threads at their inner ends, which rest in a ring or continuous plate E, and upon said hooks thumb nuts F are employed and clamped against the inner surface of the said plate or ring. I

The hooks D are made to take hold of the two pieces of fabric 0 C (see Figs. 1 and 2 of the drawings) and embrace the reeds a a, while the nuts F, engaging the screw-threaded ends of said hooks, bear against the inner face of the ring, and when adjusted tighten or loosen the fabric on the frame.

In the drawings, Figs. 3 and t show a modification in which the frame and ring E are circular, and the covering fabric is out into gores, leaving several ends in which are enseamod the reeds a, to be taken hold of by the hooks D. Nuts F are run on the screwthreaded ends of the said hooks, and when adjusted bear against the inner face of the circular ring to hold the fabric to desired tension.

The bottom in common use prior to the popular use of slats as supports to a mattress consisted of a rectangular piece of closely woven fabric provided around its edge with eyelets or openings through which passed a rope or cord, which in a zigzag line passed between the bottom and buttons fixed in the four rails of a bedstead. This old style of bed-bottom, when fixed, was quite'elastic and comfortable to lie upon, but owing to the time required to fix it in place and keep it so fixed it was superseded by the slat and other quickly-adjusted bottoms.

My device possesses all the good qualities of the old method when applied to abedstead; but has advantages over it in that it is quickly adjusted to place on the bedstead and may be tightened in a few minutes at any time. Besides these advantages, it may be said that it is superior in strength and durability, whether used for a bed, chair, chair-back, or lounge, for the reason that it is composed of two instead of one piece of material, one arranged with reference to the other, so that the warp-threads of the fabric may take the strain caused by the weight imposed.

By the use of my stretching device any person qualified to out and fit a piece of f. bric may apply a bottom or back to a chair or lounge, or he may replace an old one in a very short time.

The bottom, when applied to a chair, is very much better and cheaper than either the cane bottom, the wooden seat, or the paper seat.

It is unnecessary to state that the bottom constituting my invention may be readily adapted to either of the articles mentioned. The only thing to be observed is to have the ring used with the clamps of a form to suit the horizontal outline of the supporting-frame.

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

1. The combination, with a chair or bed-.

stead frame, a covering fabric and reeds enseamed Within said fabric, substantially as described, of the clamping device composed of an endless ring, screw-threaded hooks taking hold of said fabric, and reeds and nuts run upon said hooks and bearing Within said band to hold said fabric to a suitable tension, substantially as set forth.

2. The combination, with a chair or bedstead frame, two pieces of \VOVCH fabric (the one overlapping' the other with their warp threads crossing) folded over the ends and sides of said frame, and the strengtheningreeds for the said fabric held in told by the hooks D, of the ad justing device composed of the metallic ring and screw-threaded hooks and nuts, said hooks taking hold of the said fabric and reeds, and the said nuts engaging the screw-threaded ends of the said hooks and bearing against the inner [ace of the said ring, as and for the purpose set forth.

In testimony whereof I aliix my signature in presence of two Witnesses.

JOSEPH E. MOORE.
