METALLIC BED-STEAD.

SPECIFICATION forming part of Letters Patent N 0. 554,477, dated February 11, 1896.

Application filed July 31, 1895. Serial No. 557,703. (No model.)

To all whom it may concern: 7

Be it known that I, LEMUEL OOBURN, a citizen of the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Metallic Bedsteads, of which the following is a specification.

This invention relates to improvements in metallic bedsteads, the object of the invention being to construct a bedstead in which all or a greater part thereof shall be of metal, and yet of great lightness, simplicity, and cheapness.

An important object also is to provide a bedstead which may be most easily and quickly put together or taken apart, and which when taken apart may have the parts thereof laid most closely together to occupy but very slight space.

The invention is illustrated in the accompanying drawings described hereinbelow, and set forth in the claims.

In the drawings, Figure 1 is an elevation of the improved bedstead. Fig. 2 is a perspective view, on a larger scale, of one of the corn er castings or connection-pieces for uniting the post and side and end rails. Fig. 2 is a view, partly in section, of the lower end of one of the corner-posts of a bedstead, showing the adaptation of a caster thereto. Fig. 3 is a side view of one of the connection-pieces for uniting the post and top rail, Fig. l being a perspective view of the same. Fig. 5 is a cross-sectional elevation as taken intermediately of the bedstead and looking toward one end thereof. Fig. 6 is a perspective view of a portion of the bedstead as seen at one corner internally thereof.

Similar characters of reference indicate corresponding parts in all the views.

In this bedstead the side, end, and top rails AA B and posts 0 are composed of straight lengths of thin or sheet metal, which in crosssection comprise a U or V form as to their intermediate portions a and opposing outwardly-curled or trough-like marginal portions these bars or rails while weighing very little having great strength and rigidity.

The corner connections D for the side and end rails and posts each consist of a vertical member 10 and the horizontal members 12 and 13, which are right-angular to member 10 and also to each other. Each member 10, 12, and 13 comprises a rather high or deep central rib with the base-flanges 15, of trough form, the bars or rails being so correspondingly constructed that the former may fit closely over and upon the ribs of the latter and have the bases of the curled marginal portions a closely disposed in the trough flanges 15. The rails or bars are connected to the supports or rests therefor of the corner connection-pieces by the transversely-applied bolts 16 and the nuts 17, which hold the bars or rails against displacement in any direction, either upwardly or longitudinally.

The top rails are united to the posts by the corner connection-pieces G, which have the right-angular members that are of the same cross-sectional shape as the members of the connection-piece D, and the said connectionpieces G are connected in the same manner to the posts and top rails by bolts and nuts. Each post may have at its bottom a casting H, which comprises the socket-ed part 18 for the caster and the ribbed and flanged part 19, about which conforms the lower extremity of the post. There is a shoulder or ledge, 20, where the part 18 meets the part 19, which forms a rest for the lower end of the post. The part 18 may be driven friction-tight into the lower end of the post, being thus secured, or it may be loosely fitted, in which case a transversely-applied bolt may or may not be provided. Y

lVhile the cross-sectional form of the rails and posts described and shown is the preferred one in point of a very high degree of strength and rigidity, the invention is not to be limited thereto, because the advantages of the invention may be measurably acquired by omitting a part of the metal at one side of the bend'zr, as seen at the left in Fig. 6, the bend a; being essential, and the one edge curl being preferable, as it provides a means, in addition to imparting great strength, to resist transverse strains for the connection or suspension of the bed-bottom. As here shown the bed-bottom consists of the slats ff and the suspension-springs f. therefor, the latter having their upper extremities hooked, as seen at f to engage the curled base of the side rail.

The curled portions a of the side rails may be notched at intervals for the purpose of preventing any sliding or shifting movement of the springs.

By the provisions of the connection-pieces D and G and of rails of various dimensions any size of bedstead may be very quickly and readily produced.

Having thus described my invention, what I claim, and desire to secure by Letters Patcnt, is

1. In a bedstead, the side and end rails each having top bend as, and a curled base edge a, in combination with conneetion-pieces comprising the angular members 12 and 13, having the rib and a trough-like base-flange to which the said rails conform and engage, substantially as described.

2. In a bedstead, the side and end rails each having a top bend :20, and a curled base edge a and the posts of corresponding form in combination with conneetion pieees comprising the angular members 10, 12 and 13, each comprising a rib-like portion and a troughlike flange to which members the said rails and post conform and engage, substantially as described.

3. In a bedstead, the side and end rails each having top bend at, and a curled base edge (L in combination with e0nnection-pieces comprising the right-angular members 12 and 13, having the rib and a trough-like base-flange,to which the said rails conform and engage, and also having a vertical member, and posts with which the said vertical members are connected, substantially as described.

4. In a bedstead, a post and top rail each formed of thin metal having a V-shaped middle, and outwardly-turned edges, and a corner connection-piece which comprises rightangular members each having a rib and 0pposite outwardly-turned troughs or flan gerests, combined as described.

5. In a bedstead, the combination with the side rails formed of thin metal having a V- shaped middle portion and having the cylindrically-formed base-flanges d of the spiral springs f having the hooks f engaging said flanges a and the slats suspended from the spring, substantially as described.
