SAMUEL I. SMITH, OF SALINA, NEW YORK.

MODE QF CONSTRUCTING BEZDSTEALDS.

speeieetien of Letters Patent No. 99o, dated october 26, 1838.

To all 'whom it may concern .4

Be it known that I, SAMUEL P. SMITH, of

the town of Salina, in the county of Onondaga and State of New York, have invented a new and useful Improvement in tenons and mortises of bedsteads, which I denominate the Conical Tenon and Mortise, for the purpose of forming a close joint, which can always be made vtight at pleasure; and I do hereby declare that the following is a full and exact description of the said improvement.

First, the bed part and side piece, represented by Figure 1, are constructed in the usual manner, and ofthe usual size, and may be made either square, or round as shall be desired. The tenon upon `the ends of the side piece A is made of a conical form, of about two inches in diameter at its largest extremity, and gradually tapering to the end to the sizeof about one, and three fourths of an inch. Y

The mortises in the part Fig. 2, A B, should correspond with the tenon in taper, and should be about one-eighth of an inch less in diameter than the tenon. They can then be connected in the ordinary method, by bolts and screws, or by cords only; the conica-l form securing a uniformly tight joint, not liable to becomeloose by Wear, and wholly inaccessible to vermin.

so* i Round side pieces, upon which thetenonsV can be turned, varerecommended as `more economical 1n construction; but if they are preferred they can be `made four slded, and

the principle will be retained by givingthe ,tenon and mortise the pyramidal for1n. The` end pieces and parts can be connected in the same way if desired.

What I claim, and desirey to secure by The manner inv which Ihave combined and connected Athe above described tenon and mortise, whether in a round, four-sided or other form, for the purpose of forming a tight andV strong joint, which shall not` become open or loose by use; that lis to say I claim the application of the prin-` ciple, by which'tenons and mortises, larger at one extremity than 4the other, of a regular tapering frame, are combined and connected in the construction of bedsteads,` in

the manner above set forth. j

SAMUEL P; SMITH.
