MARSHALL LEFFERTS, OF NEW YORK, N;

METALLIC BEDSTEAD.

specification of Letters Patent No. 14,668', ated April 15, 185e.

To all whom t may-concern Be it'known that I, MARSHALL LErrER'rs, of the "city, county, and State of New York, have invented, made, and applied to use certain new and useful Improvements in Corrugated-Iron Camp-Bedsteads; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1, is a plan of the bedstead as open ready for use, Fig. 2, is a vertical, longitudinal section, and Fig. 3, represents the side of the bedstead when folded together for transportation.

Similar marks of reference indicate the -same parts. e

and one that will not be bent down or dam-v aged by any ordinaryweight, but will keep the mattress out flat and in the most co-mfortable position for the party making use of the same.

a, a, are metallic bars of an angular or L-form running along the ledges' of the bedstead bottom and forming the side rails. The horizontal parts of these L formed bars are inward or toward each other and receive the bars Z9, which are of corrugated or ['L shape sectionally. These bars 5, I), sit onto the lower parts of the angle iron a, seen in Fig. 4, and are secure-d thereto by rivets or otherwise, so that the vertical part of the angle iron a, covers or closes the ends of the corrugated bars Z), b, producing a handsome and workmanlike finish. By this arrangement and construction of parts, the bars a, a, or side rails furnish t-he requisite strength longitudinally of the bedstead, while the bars b, b, support the superincumbent weight crosswise of the bedstead without deflection,

c, 0, are metallic straps running lengthwise of the bedstead at suitable distances to sustain the mattress; and riveted or otherwise attached to the cross bars b. If these upper` straps c, 0, only were used, the inequalities of weight on the bed might twist the corrugated bars b, b, or allow the thin met-al of which they are composed to spread on the lower part of the corrugation and Ygive down. Io prevent this I make use of 'rails a, by tie rods 2 and 3, and at* the middle the legs e, e, are secured by the rivets or screws of the joints l, 1.

4, 4, are tie rods connecting the lower ends of the pairs of legs e, e, and from these tie rods 4, 4, diagonal braces f f," extend to the side rails a, a, where each is secured by a hole and slot which is passed over a stud and drop pin 5, shown in larger size in Fig. 5, to attach the upper ends: of said braces firmly in place.

g, is a metallic head frame attached by means of the tie rod 3, see Figs x1, and 2, so that the same can be turned up or down.

When the bedstead is to be shut up for transportation the head frame g is first to b-e turned down, then the bot-tom is to be folded together with the head frame between, and the braces f f are to be disconnected, t-he legs turned up, and the braces shut past each other as seen in Fig. 3; and to give room for the braces f, in this position the legs are slightly removed by a washer, sufficient to allow the braces f to pass between the legs and side rails a.

It will thus be evident that I construct the said bedstead in a very strong and substantial manner, the parts being so shaped and fitted that the greatest strength can be obtained with the least possible weight of material, and that the general arrangement and construction of the parts gives facility for folding compactly for transportation.

I do not claim angle iron in itself neither do I claim [L shaped orcorrugated metallic bars as both these forms of metal are well What I claim and desire to secure by Le..- t-ers Patent is* The combination of the angle iron side rails a, with the Corrugated or ['1 formed cross bars (b) and straps c, and d, in the manner and for the purposes specified.

In Wit-ness whereof I have hereunto set 20 my signature this fourteenth day of N0- Veniber 1855.

MARSHALL LEFFERTS.
