- Application filed April 5, 1911. Serial No. 619,100.

To all whom it may concern:

Be it known that I, JOHN M. ADAMs, a citizen of the United States, and a resident of Chicago, in thecounty of Oookand State of Illinois, have invented certain new and usefullmprov'ements in Metal Bedsteads, of which the following is a specification.

This invention relates to metal'bedsteads.

As is" well known, ornaments, usually made of sheet brass or other thin ductile metal, are very commonly applied to the joints between. different members of 'metal bedsteads'for the purpose of imparting a neat and pleasing appearance to the bed stead The object of my present invention is to provide improved and simplified means for securing ornaments for metal bedsteads in position, without the use of screws or the like.

To this end, my invention comprises the various features, combinations of features and details of construction hereinafter de-.

scribed and claimed.

In the accompanying drawing, in which my invention is fully illustratedFigure 1 is a fragmentary side viewof two hollow members forming part of the head or foot of a bedstead having an ornament secured thereto in accordance with my invention. Fig. 2 is a vertical sectionalview thereof. Fig. 8 is a diagrammatic view substantially similar to Fig. 2, just before the connection is made and illustrating the manner of making the connection; and Fig. 4 is a sectional plan view on the line 44 of Fig. 2.

Referring now to the drawings, the reference numerals 1 and 2 designate, respectively, members of a metal bedstead, as for example, a tubular cross member of a head or foot of a bedstead, designated 1, and an upright rod or spindle, designated 2, connected thereto, and 3 is an ornament applied to the joint between said members 1 and 2, in accordance with my invention.

The ornament 3 forms a sleeve which surrounds the rod or spindle 2 and, in accordance with my invention, is secured in position in the followingmanner :Formed in the side of the hollow member 1 is a hole 4, which is adapted to receive the end of the rod or spindle 2. Said hole or opening is made larger than the end of the rod or spindle 2, which engages the same, the difference in size being substantially equal to 7 flange 5 is formed.

- In practice, the expansion of said ornament to effect interlocking of the flange 5 thereon with the inner surface of the transverse member 2 aroundthe hole or opening 4 therein, may be conveniently effected by the process of inserting the end of the rod or spindle 2 through the opening 4 in the member 1, in the following manner :The opening inthe end of the ornament 3 on which the flange 5 is formed, is made smaller than the corresponding end of the rod or spindle 2, this difference in size corresponding to the desired expansion of said sleeve. The sleeve is then placed over the end of the rod or spindle 2 with the end of said rod or spindle bearing against the inner side of said ornament around the flanged end thereof. The flanged end of the ornament 3 is then inserted through the hole or opening 4 in the member 1, the relative positions of the parts at this stage of the operation being shown in Fig. 3. Pressure is now exerted endwise on the rod or spindle 2 to force it through the flanged end of the ornament 3, which, owing to the ductility of said ornament, will operate in an obvious manner to expand the flanged end of said ornament and cause the flange 5 thereon to expand into interlocked engagement with the inner surface of the member 1 around the hole 4 in the manner desired.

Not only will the rod or spindle 2 operate to secure the flange 5 in engagement with the hollow member 1, but said ornament will have strong frictional engagement with said rod or spindle 2, which will, in turn, operate to hold said rod or spindle in position. Both said ornament and said rod or spindle will thus be secured in position without the use of screws or bolts, in the manner desired.

1. A hollow member of a bedstead or the like, provided with an opening in the side thereof, a hollow ornamentand means for securing said ornament into the opening in the side of said hollow member, said means comprising an out-turned flange on said ornament adapted to enter the opening in said hollow member and to be interlocked with said hollow member within the same by expansion of the portion of said into said hollow bedstead member, the flangeon said ornament being initially smaller than the hole in said hollow member and the hole through the portion of said ornament on which said flange is formed being initially smaller than said second bedstead member, the relation being such that inserting said second bedstead member through said ornament will expand the portion of said ornament on which said flange is formed and will interlock said flange with said hollow member within the hole oropening therein in which'said ornament. is secured, substantially as described! '8. A' bedstead, comprising a hollow first member, a second member and a hollow ornament, said hollow first member being provided with a hole in the side thereof and said ornament being expansible and having a flange formed thereon initially smaller than the hole in said hollow'first'member, and said second member inserted through said ornament into said hollow 'first'memher, the opening through said ornament being initially smaller thanjthe end of the second member, the relation being such that mserting said second member-through said ornament will eXpandsaid ornament and interlock the flange thereon with the hollow first member around the hole therein within said hollow first member, :substan presence oftwo subscribing witnesses, thi 28th day of March, A.
