JASPER JOHNSON, OF GENESEO, NEW YORK.

BEDSTEAD-FASTENING.

Specification of Letters Patent No. 9,073, dated June 29, 1852.

To all whom t may concern:

Be it known that I, JASPER JOHNSON, of Geneseo, in the county of Livingston and State of New York, have invented a new and useful Improvement in Bedstead-Fastenings; and I do hereby vdeclare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is an inverted view of the fastening, the better to exhibit the mechanism ofthe double or second plate and spiral screw bolt. Fig. 2, a sectional view of the post and rail secured' by the fastening. 3, an exhibition of my method of substituting suitable sized wire for the hemp cording.

The nature of my invention consists in so constructing a fastening for bedsteads, that they may be readily thrown down, as in case of fire, hurry, etc., as the bolt securing the rails to the posts can be withdrawn without the necessity of slacking the sacking, simply by turning a knob or handle at each joint; it also obviates the objection to the incline plane and bolt fastening now in use, viz, that they are not applicable to the square rail or the present French bedstead, whereas by my improvement, using ak double plate instead of a single one forming the incline plane in connection with the spiral screw acting on said second plate the operation of plane is changed, inasmuch as instead of t-he bolt and stub turning, the plane is drawn under the stub, and the joint formed.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, refer ring to the drawings of which- B, Fig. l, is the square portion of the post c, a metallic plate let into the same and secured by two wood screws, a view of e is given in Fig. 4, exhibiting the recess 7c, for -the second plate, formed with cogs cl on its edge, an incline plane 7L and opening I, for the bolt O Fig. 2. to enter: f, a bolt with spiral thread meshing into the cogs d and, serving to rotate it; g, the handle by which f may be turned: in Fig. 2, A is the rail, which if the wire cording is to be used may be Octagon or round; C, a metallic boli secured in the end of the rail.

Fig. 3 exhibits a bedstead with the wire cording, the pegs or knobs around which the wire is passed are larger than those usually inserted, so as to make the mesh at their crossing' larger.

The operation of my mode of fastening requires but slight additional explanations, as by the inspection of the drawings, it will be perceived that on turning the bolt j", the incline plane h, will be forced or wedged under the stub on the bolt C, and thus draw said bolt through the opening I and make a perfect joint between the rail and side 'of the post. The advantages have been already adverted to, but would add, that by the perfection of the joint and the metallic cording insects are prevented from nding a lodging place, while the cost of construction is a mere trifle.

Having described the nature and use of my improvement, I do not claim a bedstead fastening composed of a stub bolt drawn tight on an inclined plane, as that is well known: but

That I do claim, and desire to secure by Letters Patent, is-

The combination of the fastening, composed of the stub bolt C, and the inclined plane 7L, cr their equivalents, drawn tight by the cording of the bedstead, with the endless screw f acting upon the inclined plane L by means of cogs d, or other equivalent device, in order, by turning the inclined plane under the bolt C, to loosen, separate or tighten again the fastening, without the necessity of slacking the cording.

In testimony whereof I have signed my name before two subscribing witnesses.

JASPER JOHNSON.
