Letters Patent No. 106,382, dated August 16, 1870.

IMPRO'VED BEDSTEAD-FASTENING.

The Schedule referred-to these Letters Patent and making part of the same.

To all whom it may concern Be it known that we, PRES. `MAULDING and JOHN U. FRALEY, ofv Marshall, in the county of Harrison 'and State of Texas, have invented anew and useful Improvement in Bedst-ead-Fastening; and we do hereby declare that the following is a full, clear, and exact .descriptionthereo which will' enable others skilled in the art to make and use the same', reference being had to the accompanying drawing forming part ot' this specification. v

This invention relates to a new and useful improvement in mode of fastening the rail to the posts of bedsteads, whereby many of the objections to the ordinary bedstead-fastening are obviated; and

It consists in a lock-joint formed by. lugs operating on inclined planes, by means of which the parts are drawn "together, and in a spring bolt, by-means of which the parts are held tightly together, as will be hereinafter more fully described. l

In the accompanying drawing-v Figure 1 is a vertical section ofthe fasteningv on the line x a: of fig. 2; A

Figure 2 is a vertical sectionof fig. 1, on 'the line Similar letters of reference indicate corresponding paits.

A is the bedstead-post; B is the rail; C is the cavity formed in the side of the post; and D is the metallic plate fastened therein by chamhering out the cavity and fitting the edges and lower end of the plate thereto, and then fastening tbe'plate by a single screw, as seen in fig. 1.

E E represent inclined planes on the inner side of this plate, and F F are orifices through it forv the introduction of the fastening-lugs.

G represents a plate Yof metal, which is rigidly attached to the side of the rail with its edge and flange H flush with the end of the rail.

I I are the fastening-lugs, which project from the edge of the plate, with lips, J, on their sides, as seen in dotted lines in fig. 2.

rI he lugs, with the lips, enterl the broad portion of.

the orifices F, and, as the rail is forced down, the lips J engage with the inclined planes E' E, and serve to draw the rail up to the post and make a tight joint.

The orifices F F in the plate D are separated by the cross-bar K.

L is a spring bolt. which passes through the flange H 'and enters the chamber or cavity C beneath the bar K, as seen in the drawing. This bolt securely holds the rail in its place and allows the bedstead to be lifted or moved about withoutdanger of being loosened or coming to pieces.

M is a finger-piece on this bolt, by means of which the bolt is drawn back when the rail is to be removed from the post.

The bolt operates upon the face or outside of the plate G, and is confined thereto by the cap' N, the screws, o o, of which held the plate to the rail. By thistastening the mil and the post are tightly joined together, no cracks being 'left for theentrauce ot' vermin, while th'e possibility of the'joint being loosened is prevented.

Having thus described our invention,

We claim as new and desire to secure by Letters Patent- A bedstead-fastening, formed by'the combination vof plates D and Gr, inclined planes E E, lugs I I, with the lips J and bolt L applied, arranged substantially as described.
