BEDS'I'EAD-JOINT.

A plication filed April 17, 1914.

1 '0 all (c/mm. it may concern Be it known that I, JosEPiI DUKE, a citizen of the United States, and a resident cl rcattle, in the county of King and State oi lv ashin 'ton have invented a new and.

improved Bedstead-Joint, of which the following is a tall, clear, and exact description.

- This invention relates to metal bedsteads and has to deal more particularly with joints between the side bars or s rin frame and the corner posts of the head and foot pieces oi. the bedstead.

The invention has for its general objects to improve the construction of bedstead joints of the type disclosed in my pending application for Letters Patent of the United States, Serial Number 82%,117, filed March 12, 1914, the invention residing in certain novel means for detachably connecting the bracket element of the jointto thecorner post of the bedstead.

Another object of the invention is the provision of a durable and, sulistantial box bracket having novel and effective means for i zistening thereto a cross-bar extending from the box bracket at one side of the bedstead to the "acket at the opposite side.

A further object of the invention is the employment of a bracket having a lug or equivalent means extending into a corner post through an opening in the latter, the lug being so designed as to interlock with a wedge or equivalent means whereby the bracket is fastened to the post.

Vith these objects in view, andothers wl'iich will appear as the description proceeds. the invention comprises various novel features of construction and arrangement ot parts which will be set forth with particularitv in the following description and claims appended hereto.

in the accompanving drawing which illus trates certain embodiments of the invention and Wl'ierein similar characters of reference indicate corresponding parts in all the views, Figure 1,is a perspective view of a box bracket applied to a. corner post; Fig. 2 is a. perspective view of the box bracket detached from its co. ner post; Fig. 3 is a vertical section through the. box bracket to show the means tor connecting the same with the corner post; Fig. 4 is a horizontal sectional view on the line 4-4,.Fig. 3; Fig.

5 is a perspective view of a portion of a corner post: Fig. (i is a perspective view oi the lugcarrrymg element that connects the Specification of Letters Patent.

Patented Jan. 19, 1915. Serial No. 832,515,

box bracket to the corner post; Fig. 7 is a perspective view of one end of a side bar which extends into a corner bracket and is fastened thereto and to the post and bracketconnecting element; and Fig. 8 is a perspective view of a strengthening or joint stiffening element interposed between the bracket and corner post.

Referring to the drawing, A designates a corner post, I? the bracket to which a bed stead side bar or spring frame is adapted to be connected. G a. cross bar extending from the bracket at one side to the bracket 7 at the opposite side, D the connecting element which unites the bracket B with the post A.

The post A is otan ular or any other desired cross-section and is provided with a rectangular opening 1 for receiving the means that secures the bracket l) thereto. The bracket B is of a box type, such as that shown in, theapplication hereinbei'ore referredv to, and consists of two sections 2 and 3 which are formed as shown in Fig. A: with end walls -land 5 respectively which overlap. and these walls have openings 6 and 7 which register with each other and with the opening 1 of the corner post. The section 3 has upper and low. plate portions 8 and 9 which form the ton and bottom respectively of the box bracket, and these plate portions have flanges 8 and 9", respectively, at the ends presented to the corner post, and be tween these flanges the end wall 4: of the sec tion 9 engages. as clearly shown in Fig. 5. The portion 8 has a recess 10 in its side edge to receive an i'ipwardly extending ear 11 on the section 2, and from the inner end of this recess extends an upwardly-cxtcnding ear 12. which cars may be fastened together bv av rivet l3 and constitute a lug, which is adapted to engage in an opening provided in the side bar oi? the bedstead. The section 2 has a laterally extending base flange ll which has an opening 15 to receive a lug on attaching device D is made of sheet metal and comprises a loop which forms a lug 17 and the ends of the loop are provided with cross bars 18 which form the base of the connecting device. The cross bars 18 engage the apertured wall of the box bracket and the wedge E passes through the lug 17 and engages the interior surface of the post, so that the connecting device D causes the box bracket to be clamped firmly and irnmovably against the corner post A.

The section 3 has its side wall provided with an .L-shaped opening 20 through which the end 21 of the cross-bar C enters the box bracket, and the vertical flange 22 of the cross bar C has an aperture 23 to receive a lug 24: on the attaching device D. In as sembling the cross-bar the same is inserted into the bracket slantinglv, as shown by dotted lines in Fig. 4, and when fully inserted the cross bar is moved to a position at right-angles to the box bracket, whereupon the lug 24 enters the aperture 23, as shown by full lines. The securing of the cross bar to the bracket is completed by a bolt 25 which passes through apertures 26 and 27 inthe top of the bracket and horizontal flange 28 of the cross bar. In addition to the rivet 13 for holding the sections together. a lug 29 is provided on the bottom 9 of section 3 and enters an opening 30 in the section 2, the end of the lug 29 being hammered down as a rivet.

To increase the rigidity between the bracket and post, a stiffening or strengthening element F. such as is shown in Fig. 8, is employed. This element comprises a plate 31 which is interposed between the post A, and the bracket B, and has lugs 32 at its top and bottom for engaging the corresponding parts of the bracket B, and it also has a lateral flange 33 to form an angle with the plate 31 so as to engage two sides of the corner post, as shown in Fig. 4. By means of these flanges the bracket is held rigidly on the post and anv tendency of the bracket to twist or turn on the lug 17 of the attaching device I) as an axis is prevented. If desired, however, this element F canbe omitted, especially where round corner posts are used, and the end of the bracket B is shaped to conform to the curvature thereof.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood bv those skilled in the art to which the invention appertains, and while I have described the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such'changes may be made when desired as are ithi n the scope of the appended claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

.box bracket having an opening in it; side,

means for securing the box bracket to the post, a lug on the said means, and a crossbar extending into the bracket through the opening and having an aperture for receiving the said lug.

- 8. The combination of a corner post, a box bracket having an owning n its side, means for securing the box bracket to the post a lug on the said means, a cross-bar extending into the bracket through the opening and having an aperture for receiving the said lug, and a bolt connecting-the cross-bar and bracket togethmin addition to the Siliti lug.
