BEDSTEAD CORNER-FASTENING.

Specification of Letters Patent.

Patented Apr. 20, 1920.

Application filed July 16, 1919. Serial No. 311,259.

To all whom it may concern:

Be it known that I, MORRIS SoHLnsINcnR, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bedstead Corner-Fastenings, of which the following is a specification.

The present invention relates to bedstead corner-fastenings, that is to say to a device for coupling the side-rails of bedsteads to the corner-posts thereof. More particularly, the invention pertains to corner-fastenings applicable especially to wooden bedsteads, having corner-posts of quadrangular crosssection.

The main object of the invention is to provide a corner-fastening, the two locking members of which are exactly alike in construction, whereby a simple and inexpensive device is obtained that can be manufactured on a commercial scale or, in other words, one which is not so difficult to produce as to be beyond the reasonable cost of such a contrivance.

Another object of the invention is to so devise the fastening that the side-rails are adapted to closely abut against the corner posts, without necessitating the provision of mortises in the said posts.

/Vith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a sectional view taken through one of the corner-posts and side-rails of a bedstead, with the fastening in position thereon; Fig. 2 is a side elevation of the two members of the fastening, in engagement; Fig. 3 is a front elevation of one member of the fastening; Figs. 4, 5 and 6 are sections taken, in their order, on lines 4L4, 55 and 6-6 of Fig. 3; and Fig. 7 is a perspective view of the two members of the fastening, disengaged.

In the drawings, the numeral 10 indicates one of the corner-posts of a bedstead, said corner-post being of quadrangular crossseotion. Against the inner face 11 of the post abuts one of the side-rails 12 of the bed frame. This side-rail is made in the form of a wooden board, provided in its end, that is juxtaposed to the face 11 of the corner post, with a vertically extending mortise 13. lVithin this mortise are disposed the members 1 1 and 15 of the corner-fastening, the member 14 being attached to the cornerpost and the member 15 to the side-rail. These two members are exactly alike in construction, but inverted in relation to each other, as will hereinafter appear.

Each fastening member comprises a metallic plate 16 of oblong configuration, that is adapted to be attached to the respective element of the bedstead by screws 17, the heads 18 of which are countersunk, so as not to interfere with the other element of the fastening. In the longitudinal axis of the plate 16 is disposed a dove-tailed lug 19 of oblong configuration, the thickness of the said lug corresponding to the thickness of the plate, thereby permitting the lug to be disposed wholly in the plane of the plate. The free edge 20 of the lug is undercut, as clearly shown in Fig. 6 of the drawings, and so is the transverse edge 21 of the body portion of the plate adjacent the said lug. From the body portion of the lug projects outward a fiat projection 22, the thickness of which corresponds exactly to the thickness of the plate, or, in other words, the plate has a double thickness at the said projection. This projection extends from the transverse edge 23 of the plate 16 toward and beyond the transverse center line of the said plate, and is provided fin the longitudinal axis of the latter with the dovetailed groove 24;, its transverse edges 25 ad jacent the transverse center line of the plate being undercut, as clearly shown in Fig. 6

of the drawings. The transverse edge 26 of the groove in proximity of the transverse edge 23 of the plate 16 is also undercut. The size of the groove is such as to be adapted to receive the lug of the other plate member of the fastening.

One of these plates is secured to the face coinciding withthe longitudinal axis of the face 11 and its lug 19 projecting upward.

The other member of the fastening is disposed within the mortise 13 of the rail 12, its longitudinal axis running vertically and its lug 19 projecting downward. In other words, the two members are fastened to the two elements of the bedstead in inverted positions relative to each other.

In order-to mount the rail upon the corner'post, the former. is brought into abutment with the face 11 of said post above the lug 19 of the member 14, and then allowed to slide downward, whereby the lug 19 of the member 14 is seated in the groove 24 of the member 15 and the lug 19 of the member 15 slides into the groove 24 of the member 14. The mortise 13 is of a width that corresponds to the width of a member of the fastening, and of a depth that corresponds to the thickness of the plate 16 at its fiat projection 22. Owing to this arrangement, the two members of the fastening are guided as they slide one into the other. Inasmuch as the lugs and grooves of the two members of the fastening are dove-tailed, and also because the edges 20, 21, 25 and 26 of the two members are undercut, the rail is securely held upon the bedstead and prevented from movement in all directions, that is to say it is safely held against downward movement, longitudinal movement and transverse motion;

By raising the side-rail, the two members of the fastening are disengaged," thereby disconnecting the rail from the post.

Inasmuch as the depth of the mortise 13 corresponds to the thickness of a plate member at its fiat projection 22, the fastening is wholly concealed from view.

What I claim is: V

A corner-fastening for bedsteads comprising two members, each consistingof a plate having a clove-tailed oblong lug at one of its ends, the thickness of said lug corresponding to the thickness of said plate, said lug being wholly disposed in the plane of said plate, and a flat projection on said plate provided with a dove-tailed groove, said projection extending throughout the width of said plate from itsv end opposite said lug toward and terminating at about the transverse center line of said plate, the thickness of said pro ection corresponding to the thickness of said plate, said two members being arranged in opposition to each other with their projections in abutment with each other and their lugs seated in the groove of the other member of the fastening.

Signed at New York, in the county of New York, and State of New York, this 5th day of June, A. D. 1919;

MORRIS SCHLESINGE'R.
