METAL BEDSTEAD.

Specification of Letters Patent.

Application filed August 6, 1913. Serial No. 783,264.

To (ZZZ whom it may concern.

Be it known that 1, MAX DUNNER, a cit-izen of the United States, and a residentof ih'ooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Metal Bedsteads, of which the following is a specification.

The invention pertains more particularly to a novel construction of the corners of the upper ends of the end frames of metal bedsteads whereby the upper end of said end frames may be formed of rectangular tubing and have its end portions properly bent downwardly at right angles to join the corner posts of the end frames. It is desirable in many instances that the corner posts and transverse rails of the end frames of metal bedsteads be of rectangular formation in cross-section, and great difliculty has eX- isted in so shaping the ends of the upper transverse bars of the end frames as to present a desirable appearance. It is extremely diflicult to bend a piece of rectangular tubing on curved lines, and especially so in attempting to bend the ends of the tub ing on the short curves that are required for the upper corners of end frames of metal bedsteads of customary size.

The object of my invention is to provide a construction whereby the ends of a piece of tubing, rectangular in cross-section, may be bent downwardly on graceful curved lines and thereafter be used as the top rail or member of the end frame, either head or foot, of a metal bedstead, the piece of tubing having its ends thus bent downwardly being adapted for connection with the usual corner posts for the bedstead, said corner posts also being rectangular in cross-section and corresponding in diameter with the said top rail or upper member.

In carrying out my invention I form the top member or upper rail of the frame from a sheet of metal and cutout the same at its end portions in a special manner to constitute the whole sheet as a blank from which the said upper member and downwardly extended outer portions are to be formed, and. said invention will be fully understood from the detailed description hereinafter pre sented, reference being had to the accompanying drawing, in which:

Figure 1 is an elevation of the end frame of a metal bedstead embodying my invention, the same being shown on a small scale; Flg. 2 1s a top view of the blank, also shown on a small scale, from which the upper mem her or top rail of the end frame and the corners thereof are formed; Fig. 3 is a perspectlve view of one portion of the upper member or rail of the end frame as formed from the blank shown in Fig. 2 but in the stage it presents prior to the end portion of the tubular member being bent downwardly to form the corner of the said end frame; Fig. 1 is a corresponding perspective View of one end portion of the upper rail or tubn lar member after the end portion thereof has been bent downwardly in the formation of a corner of the end frame; Fig. 5 is a \ertical section through a portion of the upper member or rail of the end frame after the latter has reached its completed condition, the section being on the dotted line 5--5 of Fig. 7 Fig. 6 is a horizontal section througl'i a portion of the completed upper member or rail of the end frame taken 011 the dotted line 66 of Fig. 7, and Fig. 7 is a vertical section through a portion of the upper ail or member taken on the dotted line 77 of Fig. 6.

In the drawings, 10 designates the end frame, either head or foot, of a metal bedstead, which with the exception of the pres ence of my invent-ion in the upper member or ail 11 thereof, of customary construction, the corner posts being designated by the numeral 152 and the sockets for receiving the side rails of the bed by the numeral 13. The upper member or rail 11 is rectangular in cross-section and is connected with the corner posts 12 by means of castings, commonly called chills, 14. My invention resides wholly in the formation of the upper member or rail 11, and particularly in the coin struction of the end portions of said membcr whereby downwardly extending ends 15 may be formed thereon to match the upper ends of the corner posts 12 and be connected therewith by the chills 1d.

The upper member 11 of the end frame is formed from a sheet metai blank 16 shown in detail in Fig. 2, said blank in carrying out my invention being bent to constitute the transverse bar 17 and the said dowiiiwardly extending ends 15. :l indicate by dotted lines in Fig. 9 the lines on which the blank 16 is to be folded to create the rectangular Patented Oct. 28, 1913.

member 11. shown in Fig. a, which has an outer face 18, an inner face 19, and two side faces 20, 21. The dotted lines 22, in Fig. 2, define the panel from which the outer face of the bed member 11 is formed, and said dotted line with the dotted line 2st de lines the panel for the side 20 of the bed member 11, while said dotted line 2a and the dotted line 25 define the panel for the inner face 19 of said bed member 11, and the dotted line 22 with the dotted line 26 defines the panel from which the other side 21 of the bed member 11 is formed. The dotted lines 22, 23, 2 1, 25 and 26, while bro-ken at the spaces cut in the blank adj a cent to the ends thereof, extend to the extreme ends of the blank, except at such cutaway portions, and therefore the outer and inner and side panels of the bed member 11 are present finally in not only the trans verse horizontal bar 17 but in the end portions 15 of said bar. Outwardly from the dotted line 25 and between said line and the extreme adjacent edge of the blank 16, the metal is bent inwardly, as at 27, to form a flange extending lengthwise of one edge of the inner panel 19 of the bed member 11, and between the dotted line 26 and the eX- treme adjacent edge of the blank 16 th metal of the blank 16 is bent inwardly on the dotted line 28 and then outwardly to form a pocket extending lengthwise of the bed member 11 to receive the aforesaid flange 27, as shown in Figs. 3 and 5, the pocket 29 being disposed within the outline of the bed member 11. so as not to disfigure the same and in use cooperating with the flange 27 to lock the blank in its rectangular formation. I preferably apply solder to the joint between the flange 27 and pocket 29 so that even with rough usage there may be no danger of the seam in the adjacent edges of the bed member 11 formed from the blank 16 opening. The turning inwardly of the flange 27 and pocket 29 leaves the face 21 of the bed member 11 substantially smooth and uniform throughout.

Those portions of the panels of the blank 16 to constitute the sides 20, 21 of the bed member 11 are cut out as at 30 and 31, at the points which in the transformation of the blank into the bed member 11 will constitute the corner portions of said bed member. The recessing of the blank 16 at 30, 31 is special in that thereby are formed between the dotted lines 23, 2st corresponding facing somewhat triangularly-shaped sections 32 having straight edges on one side and curved edges on the other side, and that thereby are also formed similar sections 33 between the dotted line 22 and the adjacent outer edge of the blank 16. That portion of the blank 16 between the dotted lines 22, 23 extends continuously from one end to the other of the blank, and between the reecsses 30, 31 formed in the blank there is created in said part of the blank between the dotted lines 22, 23 sections 3st which are free to be bent over and downwardly, as at (Figs. 4 and 7) to form the outer corners the bed member 11, the sections being a single piece and flat and adapted to be readily bent on curved lines to create such corners, and it will be seen, on reference to the drawings, that when the sections 3 1 are bent downwardly, as at 35, to form the outer corners of the bed member 11, the curved edges of the sections 32, 33 fit snugly below the outer edges of such corners, while the other or mitered edges of said sections 32, 33 come together along the line 36 (Fig. 4) and make a proper finish for the side faces of the bed member 11. The sections 3% of the blank 10 are bent over on curved lines, and the curved edges of the sections 32, 33, by fitting within the edges of the said sections 34: when the latter are bent downvardly, serve to strengthen the outer corner portions of the bed member 11 and impart to the article that strength which the upper portion of a head-frame or foot-frame ought to have.

That portion of the blank 16 between the dotted lines 2%, 25 instead of being continuous to correspond with that portion of the blank between the dotted lines 22, 23, is slit transversely, as at 37, in line with the trans verse center of the recesses 31 to form lips 38 which, in the formation of the bed member 11, may be bent inwardly on the jointline 36 between the sections 32, 33 and soldered together as in Fig. 7 to additionally secure a rigid formation in the end portions of the bed member 11. In carrying out the invention 1 not only solder the lips 38 together at each corner of the bed member 11, but also solder the curved edges of the sections 32, 33 to the outer panel of said bed member, so that finally my structure is a very secure and rigid one, capable of withstanding considerable rough usage. After the blank 16 has been folded to form the straight construction shown in Fig. 3, the lips 36, 36 are bent inwardly on corresponding lines for the end portions, and the rectangular structure shown in Fig. 3 is bent downwardly on lines extending transversely of the sections 3% of said blank, thus, with the exception of the proper soldering, completing the entire bed member 11, ready for application to the other portions of the head or foot frame of a bedstead. The bed member 11 produced in accordance with my invention is rectangular in cross-section, of very rigid and durable structure, of uniform cross-section across its transverse bar portion 17 and vertical end portions 15, has a nicely curved outer surface at each corner and at the inner surface of said corners has a definite right-angular formation. The

bed member when completed will be applied to the corner posts 12 by chills or castings 14.

What I claim as my invention and desire to secure by Letters-Patent, is:

An upper tubular member, rectangular in cross-section, for end frames of metal bedsteads comprising a horizontal transverse portion and vertical end portions integral therewith for connection with the corner posts of said frames, the outer wall of said member being uniform throughout and at the corners thereof on curved lines and the inner wall of said member at its inner corners being on right-angular lines, and the adjacent ends of the sides of said horizontal and vertical portions of said member constituting corresponding projections having outer curved edges fitting said curved corners and inner straight edges engaging each other diagonally at the corners of said bed member.
