BEDSTEAD-FASTENING.

Specification of Letters Patent No. 10,731, dated April 4, 1854.

To all whom, t may concern Be it known that I, EASTMAN BALL., of the town and county of Kalamazoo, in the State of Michigan, have invented a new and Improved Mode of Fastening the Rails to the Posts of Bedsteads; and I do hereby declare that the, following is a full and exact description thereof, reference. being had to the accompanying drawings, making a part of this specification, in which- Figure l, is a side elevation of a bedstead; Fig. 2, a sect-ion cut through the center of one of the posts and a portion of a rail; and Fig. 3, a side view of a section of a post and the sustaining bracket .with its fastening pin secured thereto.

Similar letters refer to corresponding parts in all the figures.

The nature of iny invent-ion consists in fastening the rails to the posts of a bedstead by means of sustaining brackets a, secured to the posts, and conical fastening pins Z), rising from the outer extremities of the said brackets and fitting into conical holes in the under sides of the rails; the said conical fastening pins, (5,) and the conical holesin the rails which receive them, being in suc-h positions, respectively, that when the rails are forced down upon the faces of the brackets, the posts will be drawn inward and be tightly pressed against the ends of the rails; and when the rails are slight-ly elevated from the faces of the brackets, their fastening will be freely loosened'to allow the bedstead to be taken to pieces. v

Each sustaining bracket a, and its fastening `pin o, l shall generally have cast in one piece, of iron, or other suitable metal. The conical holes inthe rails which receive the coii'ical fastening pins, may be simply formed in the wood by any suitable- Vinstrument. The brackets are intended for the support of the weight of the rails, and the conical pins rising from the said brackets, to fasten the posts and rails firmly together.

What l claim as my invention, and de; sire to secure by Letters Patent, is-

Fastening the rails to the posts of a bedstead by means of the combined sustaining brackets and conical fastening pins (a, 5,) secured to the posts, and the conical holes in the under sides of the rails, arranged and operating with each other substantially as herein set forth.

E. R. BALL.
