CORNER-FASTENING FOR METALLIC BEDSTEADS.

SPECIFICATION forming part of Letters Patent No. 773,283, dated October 25, 1904.

Application filed. May 20, 1904. Serial No. 208,856. (No model.)

To all ZU7L0771/ it may concern:

Be it known that I, J ESSE P. FULGHAM, a citizen of the United States, residing at Rich-. mond, in the county of WVayne and State of Indiana, have invented certain new and useful Improvements in Corner-Fastenings for Metallic Bedsteads; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in corner fastenings or couplings for metallic bedsteads by means of which the side rails may be detachably secured to the corner-posts; and it has for the object to provide a coupling which shall be simplein construction and readily secured in position.

To these ends the invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and the particular features of novelty pointed out in the appended claims.

Referring to the drawings, wherein is illustrated the preferred embodiment of the invention, Figure 1 is a side elevation of the coupling. Fig. 2 is a top plan view of the corner-post member of the coupling. Fig. 3 is a detail view looking at the interior of the parts constituting the corner-post member of coupling, said parts being separated. Fig. 4 is a perspective view of the rail member. Fig. 5 is aside elevation of the same. Fig,- 6 is a horizontal sectional view on line 00 m of Fig. 1. Figs. 7 and 8 are views of a modified construction of the post-section of the coupling.

Similar letters of reference in the several figures indicate the same parts.

In the drawings, the letter A indicates one of the corner-posts of a metallic bedstead, which may be of any desired form or configuration, but is preferably circular in crosssection.

The corner-post member of the coupling consists, preferably, of two castings B and C, each of which is cast with a semicircular recess b 0, whereby the castings may be fitted about the corner-post of the bedstead. At

'member of the coupling.

the rear one of these castings, as B, is provided with an opening 6', with which cooperates a lug 0 on the other casting, thus constituting a hinge connection between the castings, as will be readily understood. The castings when in place upon the corner-post may be secured by means of a bolt D. In the forward portion of the casting C and on the inside thereof is formed a recess. 0 one wall, of which is straight and the other, 0", inclined from top to bottom, thereby forming a recess which diminishes in width toward the bottom, as shown clearly in Fig. 3. Beyond this recess the casting is extended, as at c, and is formed with a flat inner face, which bears against the rail-casting when in place, as will be presently explained. The cooperating casting B does not extend as farforward as the casting C and is formed with a projection Z2 extending at a right angle to the main portion of the casting and having a flat face, which face extends slightly beyond the Straight wall 0 of the recess in the other casting, C. The inner edge of the flat face 6 is cut away, forming a shoulder 6 as shown.

Secured to each side rail of the bedstead is a casting or head forming the cooperating As shown, this head has a central body portion E, through which securing-bolts 6 pass for securing the head upon the rail. Fxtending upwardly and downwardly from the forward end of said. central portion E are the arms a a, curved at the upper ends at substantially right angles, as at e 0 the inner faces of said portions being curved to fit the corner-post, as shown in Fig. 1. On its inner face the casting or head is formed with a lug, a projection 0 having an oppositelyinclined face (2*, and at the front of the body portion E there is a projection 0 extending at right angles to the body portion having a flat face, which is adapted to bear against the fiat face of the projection b on the casting B, as shown in Fig. 6. The lug or projection e" is of such a width that when in the recess 0 its rear edge does not engage the straight wall 0 of the recess.

Formed on the front face of the body portion E ofthe rail-casting on the side opposite to the projection c is a rib or projection e,

which constitutes a locking projection which cooperates with the shoulder 7)" on the casting B, as shown in Fig. 6.

With the castings constituting the eouplings secured to their respective parts all that is necessary to couple the rail to the cornerposts is to insert the lug c on the rail-casting or coupling-head in the recess in the casting 0 and then by a downward pressure the inclined wall of the lug will be caused to engage the inclined wall of the recess, thus drawing the coupling members together and bringing the flat faces of the projections 6 and a" into contact and pressing the curved end portions of the arms a 0 against the corner-post. As the lug a" does not contact against the straight wall of the .recess 0 there are but three points of contact-namely, the flat faces 6 and and the ends of the arms against the corner-post.

Lateral movement between the coupling members is prevented by means of the interlocking shoulders e and If, the parts being also braced by the extended portion 0 of the casting C bearing against the rail-casting, all as will be readily understood from an inspection of Fig. 6.

By having the lug a on the rail-casting formed with double inclines this casting may be used at either end of the rail and the corner-post castings may be used on either post by simply casting the recess 0 in the casting C, with the wall c inclined in opposite directions.

Instead of making the corner-post coupling member in two parts it may be made in one piece, such a construction being illustrated in Figs. 7 and 8. In this construction the coupling is made of malleable iron, the two parts being connected by a web F, which is bent around the corner-post, as shown in Fig. 8, and secured in place by bolts, as in the other form. In other respects the construction is the same as in the other form of the device.

lt will be seen that the coupling can be readily secured in place and that the rail may be easily uncoupled or coupled to the cornerpost.

The coupling consists of few parts and can be cheaply manufactured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is"

1. In a corner-coupling for metallic bedsteads, the combination with the post member consisting of a single piece of metal having at each end a portion of the coupling-head, one of said portions formed with a recess on its inner face and the other with a flat face extending substantially at right angles to the first portion opposite said recess; an intermediate web connecting said portions, adapted to be wrapped about the corner-post, whereby sai-l coupling portions will be brought into position to complete the head, and the cooperating coupling member carried by the rail; substantially as described.

2. In a corner-coupling for metallic bedsteads, the combination with the coupling member carried by the post, provided with a recess, and having a lateral projection opposite the recess formed with a fiat face, of the rail member provided with a lug cooperating with the recess in the post member to lock the members together, and having a lateral projection having a flat face, adapted to contact with the lateral projection, on the post mem her, and the arms on the rail member adapted to bear against the corner-post; substantially as described.

3. In a corner-coupling for metallic bedsteads, the combination with the coupling member carried by the post, having the recess therein, of the lateral projection thereon, having a flat face, formed with a shoulder, the rail member having a lug cooperating with the recess in the post member, the lateral projection, adapted to bear against the lateral projection on the post member, the projection on the front of the rail member, adapted to engage the shoulder on the lateral projection of the post member, whereby the coupling member will be held from lateral movement; substantially as described.

4. In a corner-coupling for metallic bedsteads, the combination with the post member formed of malleable iron, and consisting of two cooperating sections, one formed with a recess on its inner face and the other section formed with a flat face extending substantially at right angles to the other section and lying opposite said recess, the connecting-web, and the cooperating rail member; substantially as described.
