GARY B. SMITH, OF WOLCOTT, NEW YORK.

BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 508,056, dated November 7, 1893. Application filed August 4, 1892` Serial No.442,157. (No model.)

To all whom t may concern:

f Be it known that I, GARY B. SMITH, a citi' .zen of the United States, residing at Wolcott, 1n the county of Wayne and State of New York, have invented a new and useful Bed- 1Iottonn, of which the following is a specificaion.

My invention relates to improvements in- In the drawings; Figure 1 is a plan view of a bed-bottom embodying my improvement. Flg. 2 is aside view. Fig. 3 is a longitudinal section, showing the head-rests and legs or ksupports folded. Fig. 4 is a detail View of a Section of one of the strands, showing the concentric coils. Fig. 5 is an end view showlng the notches for the attachment of the strands to the frame. Fig. -6 is a detail View of one of the looped or double cross-strands or stays.

The frame l comprises, essentially, the parallel side-bars 2, andthe end-bars 3, which are secured upon the upper surfaces of the side-bars so that the upper edges of the endbars are above the plane of the side-bars. To the inner sides of the side-bars, near their extremities, are pivotally connected the legs 01` supports 4, the head-rest frames 5 being pivotally connected, near their lower ends, With said legs or supports, and being connected in pairs by the cross-bars 6. The headrests consist of the side-pieces 7, which are adapted to rest at their lower ends upon the licor when the bed is in its operative position, said side-pieces being extended the same distance below their pivotal point as the legs or supports; and said side-pieces are connected, at their upper ends, bythe transverse bar 7". Additional cross-bars 8 are provided at intermediate points of the sideibars, for a purpose to be described hereinafter.

The bed-bottom comprises, essentially the y longitudinal strands 9, and the transverse strands or stays lO. The longitudinal strands are attached .at their ends to the end-bars of the frame, and the transverse strands or stays are connected solely to the longitudinal strands and are interlaced between the same to hold them at the desired separation.

The strands which I prefer to use, and which I have shown in connection with the drawings, consist of coils of fine wire; and while single coils may be used with advantage, I prefer to employ double coils or concentric coils, which consist of a core or interior coil ll, anda shell or exterior coil 12, as shown clearly in the detail View, Fig. 4, each being closely or compactly coiled to permit ot equal extension. The transverse strands or stays are looped or doubled, the closed end of the loop being engaged with one of the sidestrands, and the free ends of the loop being coiled in opposite directions around the opposite side-strands. The sides of the loop are twisted together regularly in one direction and each side is passed alternately under and over successive longitudinal strands, whereby, at the intersections of the transverse strands or stays and a longitudinal strand, one side of the former rests upon the upper side and the other upon the lower side of the longitudinal strand, thus uniting allof the longitudinal strands and causing them to bear mutually the pressure of the superincumbent weight.

In Fig. 1 the longitudinal strands are shown as connected to the end-bars in the simplest manner, namely, by placing their extremities in depressions or perforations in said bars, but other ways of securing the strands to the frame may be employed, the preferred manner of accomplishing this being indicated in Fig, 5. In this construction, the outer surface of the end-bar is provided with a longi y the longitudinal strands are not necessarily formed 0f single lengths, but maybe integral IOO as indicated in the above-mentioned figure, two or more strands being connected together and secured in place by engaging their loops with the channels in the end-bars.

It will be noted that the transverse strands or stays are disposed alternately in opposite directions, namely, the closed ends of the loops are alternately enga-ged with opposite side-strands, thus adding to the strength and firmness of the bed-bottom, and equalizing the weights of its parts.

The intermediate transverse bars which are above described in connection with the headrests, act as stop bars to engage theilongitudinal strands in proximity to the end-bars to hold said head-rests and the legs or supports in their operative positions. The manner in which said rests and `supports are folded is clearly shown in Fig. 3.

Having thus described my invention, what my own I have hereto aiixed my signature in 3 5 the presence of two witnesses.
