JAMES M. BAIRD, OF WHEELING, WEST- VIRGINIA, ASSIGNOR TO HIMSELF, JOHN MCLIIRE, JAMES W.IWARD, AND JOHN BOONE MCLURE.

Letters Patent No. 102,473, dated May 3, 1870; nntellated April 20, 1870.

IMPROVED FASTENER I OR BEDSTEADS, TABLES, 8m.

The Schedule referred to in these Letters Patent and making part of the n'amo Be it known that I, J AMES M, BAIRD, of Wheeling, in the county of Ohio and State of lVest Virginia, have invented a new and Improved Fastener, of' which the following is a specification.

The nature of my invention consists in forming, in` or on each of the articles to be fastened together, or in and on plates to be attached byserews or otherwise to the articles, apointed beveled projection, 'the dis,

tance ofthe projection from the body of the article or plate being equal to its thickness at its base, and its bevel, of any desired angle, being from its point toward and down to the body of the article or plate, and as far down the edge of the projection and body of article or plate as the `selected angle produces it.

Thus constructed, the projection forms, with the articleor plate, a pointed, beveled, projecting notch. And, when two of said projections, thus provided on articles or' plates, arc mated or matched together, which is done by bringing and placing `the bevel of one with that of' the other, they form and make the fastener which I claim as my invention, ,whereby articles of manufacture for whichl it may be suitable, such as the various parts of bedsteads, tables, wardrobes, boxes, bureaus, house and other frames, Sto., may be firmly fastened together.

When plates are used I provide opposite recesses in each one, in which I place a sliding key, which, when adjusted, prevents one projection from being with-l drawn from the otheri 'But this arrangement is not necessary to complete the fastener, and may be used or not.

-the desire-d form of the thing to be fastened.

It can be either cast on, out in, or attached tothe article, as the case may require or suggest, and each by the usual methods of doing such work.

.Description of the Accompanying Drawings.

Figures 1 and 2 represent one side of the projection as formed .upon articles or plates.

Figures 3 and 4, the other side of the same.

Figure 5, two of the projections formed upon plates mated or matched together, or complete fastener; and in this casethe plates are fastened, one to the other,

at a right angle; and in which the articles or plates having the projections formed on them are marked by the letter A; the pointed beveled projection by the letter B; the bevel of projection by the letter C; the

base of projection by letter D; the recesses `by the` letter F; key by G; and the mated or matched projections or complete fastener by letter H.

What I claim as my invention, and desire to secure by Letters Patent, is-

'lhe construction of .a fastener,v consisting ofthe plates or-artioles A A, with the projections B B, bevels C C, with or withoutthe recesses F, and key G, all

arranged as and for the purpose described. j
