CORNER-BRACKET FOR BED-FRA1YIES.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed March 27, 1919. Serial No. 285,448.

1 '0 all whom. it may concern Be it known that 1, JOHN WALKER, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Cori1erBrackets for Bed-Frames, of which the following is the specification.

h iy invention relates to improvements in corner brackets for bed frames and the ob ject oi the invention is to devise a corner bracket which cannot work loose, in which all adjustments are made at the outside of the bracket where they can be readily gotten at, in which there are no dove-tail portions liable to fracture, which is so formed as to securely hold the angle side bar of the bed either in the normal or inverted position so that it will be impossible to have side play or work loose and in which the side bars of the bed frame may be connected thereto without the use of special tools and it consists essentially of the following arrangement and construction of parts as hereinafter more particularly explained.

Figure 1, is a perspective view of my corner bracket showing it attached to a portion of a bed post.

Fig. 2, is a vertical section through Fig. 1.

Figs. 3 and 4e, are perspective details of the divided portions of the locking block employed in connection with my bracket.

In the drawings like characters of reference indicate corresponding parts in the various figures.

1 indicates the bed post which is tubular. 2 indicates an inserted piece segmental in form and adapted to fit within the tubular post 1 on that side to which the corner bracket is to "be attached. The inserted piece 2 is provided with orifices 2 and 2 in proximity to each end thereof. 3 indicates my corner bracket which comprises a vertically disposed portion 3 having its interior face concaved at 3 longitudinally so as to fit the interior face of the bed post when set longitudinally thereof. The central portion of the interior concaved surface 3 is recessed at 3 in order that the bracket may grip the bed post securely and have a biting connec tion thereto at each end. 3 and 3 indicate orifices extending through the portion 3* in proximity to each end thereof and in alinement with the orifices 2 and 2. 4.- indicates rivets which extend through the alined orifices 2 and 8 and 2 and 3 thereby securely and permanently fastening the bracket portion 3* to the bed post.

8 indicates a. rectangular socket, which extends horizontally from the portion 3". 3 indicates an orifice formed in the portion 3 and in the base of the socket 1 indicates an orifice formed in the bed post in alinement with the orifice 3. 2 indicates an orifice formed in the inserted piece 2 in alinenient with the orifices 1 and 3. 41- indicates a bolt, which extends through the orifices 2, 1 and 3 and through the rectangular socket 3" so as to protrude from the end thereof.

indicates a clamping or sec-Luring block which is divided diagonally into two portions 5 and 5 as will be clearly seen in full lines in Figs. 3 and 4: and by dotted lines in Fig. 1. The plane of division not only inclines from front to rear of the block but also inclines from side to side thereby tending to force the portions 5" and 5 of the block laterally one of the other when forced together in the inserted position within the socket. The block 5 is of such a size as to leave a space between two sides of the block and the opposing walls of the socket 3* to permit of the insertion of the side angle bar 6 of the bed frame.

The outer end of the bolt 4* is threaded and provided with a wing not 7. 5 and 5 indicate orifices extending longitudinally through the block portions 5 and 5 in alinement one with the other and through which the bolt 4 extends, the orifices 5 and 5 being sufliciently large to allow the free movement of the block in the direction required.

In securing the side bar 6 of the bed frame in position within the corner bracket all that it is necessary to do is to loosen the wing nut 7 upon the bolt 4;" so as to allow of free movement of the block portions 5* and 5. The end of the bar 6 is then in serted in the position clearly shown in Fig. l and the wing nut 7 tightened thereby drawing the block portions 5 and 5 together so as to move them outwardly one from the other in an expanding direction toward the interior face of the socket 3* thereby clamping both the horizontal and vertical flange of the bar against the corresponding wall of the socket.

In some cases it is desired to insert the side bars 6 of the bed frame in an inverted socket 3*.

7 the block portions 5 and 5 upward and reinsert the bar 6 in the inverted position. The wing nut 7 is then retightened.

In order to carry the cross bar or the bed frame I have provided the socket with an angle piece 8 extending outwardly therefrom and formed integral therewith, the vertical flange 8 thereof being secured by rivets 8 to the vertical flange 9 of the crossbar 9.

- From this description it will be seen that I have devised a corner bracket which can not work loose for the reason that the portions 5* and 5 of the block 5 are wedged together in the socket 3 clamping the side bar firmly in place, in which the connection of the corner bracket to the bed post is provided without the employment of nuts located in the interior of the tubular bed post. It is very common for these interior nuts to work loose and if such should be the case it is impossible for an ordinary person to retighten the bracket as it then requires a special tool which is inserted longitudinally through the bed post to grip the nut. In my construction of bed corner bracket any manipulation which takes place is done exteriorly of the bed post and,

therefore, can be performed by any ordinary person who is the user of the bed. It has also been found in ordinary constructions of corner brackets employing dove-tail joints thatthe dove-tails are liable to fracture at the neck or weakest part of the dove-tail. By my construction this dcfeet is eliminated. Also any holes in the side bars of the bed frame are dispensed with which are usually necessary for riveting and which tend to weaken the side bar at a point where the greatest strength is necessary. By my construction also the side bar is securely and positively clamped in position and can be readily held either in the normal or in the inverted position as desired. At the same time I have provided a cheap and easily manufactured form of bed bracket.

What I claim as my invention is.-

The combination with the bed post, of a bolt secured within the bed post and extending through the wall thereof, a bracket having orifices through which the bolt passes, a side bar receiving socket carried by the bracket, opposing wedge blocks fitting within the socket and having alined orifices greater than the diameter of the bolt and through which the bolt loosely passes, the broad end of the inner wedge block bearing against the base of the socket, and a nut threaded upon the bolt and bearing against the outer end of the opposing block.
