CORNER, FASTENING FOR BEDSTEADS.

Application filed August 22, 1921.

To all whom it may concern: I

lie it known that 1, WILLIAM A. K0011, a citizen of the United States, residing at lllvansville, in the C(lllllty oi Vanderbnrg and State oil Indiana, have invented certain new and useful Improvements in Corner i astenings for liedsteads, of which the "fol lowing iii a full, clear, and. exact specific ty tion.

My invention relates to bedsteads and has reference iorc particularly to corner fastenings for metal beds using the ordinary angle side rails whereby the side rails may be reversed and adapted to support either the ordinary box spring bottoms, or ts.

in object oi? the invention is to provide a corner fastening thnt'shall be simple in construction, positive in action, and which may be used with any "form of bed posts whether o metal or wood.

Another object of the invention is to pro- 'vide a corner "fastening for beds which while jlorniing an eiiicient coupling for the side rails and corner posts will also securely lock the coupling against lateral t visting or turn ing oi? the side rails.

With the above and other objects in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter fully described and pointed out in the claim. reference being had to the accompanying drawing. forming a part hereof, in which:

Figure 1 is a perspective view showing my improved corner fastening as in use in one arrangement of parts,

Figure 2 is a similar view showing reverse arrangement of the parts,

the

Figure 3 is a transverse section taken as on line 3-3 of Figure 1,

Figure at is a vertical section of: the arrangement as shown in Fig. 1,

Figure is a perspective view oi the headed member of the "fastening which is carried by a side rail,

Figure 6 is a perspective view of a. socket member which is carried by the corner posts of the bed.

Referring more specifically to the draw-- ing it will be noted that the reference numeral 1O denotes the corner post of ametal bed, the post being indicated as of rounding formation by dotted lines it the most convenient location on the post, which may of course be polygonal or have {la t faces, the member 1.1 of the tasted Serial No. 494,342.

wings provided with openings 15 by which the wings and hence the bracket may be bolted or riveted to the corner post.

Through the front face of the bracket an opening 16 is made, the general shape of this opening being polygonal.

A narrow slot 1'? is cut through the rent face of the bracket and extends dowz'm ardl' a sui able distance below the opening 16 with which it merges. B cutting this slot through the race of the bracket spaced apart .tlanges or ribs 18' are formed and the rear face of these flanges or .ribs is sing-11th rounded or tapered to form wedge or cam faces. H

The front "face of this member 11 is flat and smooth and is bordered at each side by the vertical flanges 19-l.9 extending from the upper to the lower end of the face, the inner or opposing faces of these flanges being slightly tapered or converging from the outer edges to the face as indicated by the reference character 20, as will be plainly seen l: reference to Figure 3 in the drawing. This disposition of the side flanges results in forming virtually a wide groove in the bearing face of the bracket member.

The other member of the fastening, the fastening as a unit consisting of two members, is to be secured to the side rail 21 or cast integral with it, and consists of a stud 22 projecting 23 of the member, the stud being provided with a head 2% which extends laterally at each side of the stem of the stud.

This stud is preferably cast integral with the vertical web 25 which connects the upper and lower portion of the member, said web 25 being cast integral with said upper and lower portions and extending upwardly some distance on the back face oi the member to brace and strengthen same, as shown at 26.

Thestudded member is also provided with the vertical web 27 and the horizontal web 28 respectively which are riveted to the corresponding flanges of the angle side rail. At the edge opposite the vertical web 27 the member is provided with an inte ral vertical flange 29 which is cast integral with the body portion and the horizontal web,

from a vertical bearing face 28, serving to balance the parts and brave the member at that side.

The sides of the studded member are beveled as shown at 30, or con\"e1:*ge, the bevel being complen'lentary and correspomling to that of the flangesv 19 on the socket member.

The trai'isversely narrow stem of the stud has as before stated the la i. 'ehead 24 the inner faces of which at opposite sides of the stem has the central bearing surface 2a and tapered oppositely or curved end portions 248. Thus the head will have its greatest diameter in the plane ot the bearing surfaces and taper equally in both directions therefrom so that no matter which end of the head enters the OIX'lllDQ l6 and narrow slot 17 ot the other or socket member the central bearing surfaces will come in con tact with the rear cammed or wedge :iaces of the ribs 18 and cause the two members to be drawn tightly together when the studded member is forced downwardly.

By this arrangen'ient and disposition of the bearing surfaces of the two members, the reversal of the angled side rails is provided for so that either the ordinary box sp ing bottom may be used or slats, as desired.

It should be particularly noted that side flanges 19 of the socket inembendefine a wide groove-in the face of the member and as the width of the bearing face of the stud as the width of the bearing face of the studded member is such that it readily slides within said groove that rocking wabbling or turning of the side rails will be prevented when the members are coupled together.

Furthermore as't-he groove formed by the flanges 19 is a divergent groove and the mating end of the studded member is complementa-lly convergent, it will be seen that a very tight joint is secured, and the resistance to angular movement of the side rails is correspondingly increased.

claim:

A corner fastening for metal bmilsteads comprising a pair of castings, one oil. said castings including a flat bearing face having a keyhole slot therethrough and outwardly taperingflanges at its opposite side edges, the other casting having upper and lower flat. bearing face portions, said. portions connected centrally by an integral web extending rearwardly and upwardly, back of the upper bearing portion serfing to brace said portion, a stud or shank projecting forwardly from said web, a cammed head on said stud, said stud and head adapted to fit within the keyhole slot of the first named casting, the side edges of the stud carrying casting rerersely tapered to fit within the flanges of the first casting, and be d awn tightly thereto by cam action of the stud head.
