Letters Patent No. 90,568, dat-ed May 25, 1869.

.. i IMPROVED BEDSTEAD-FASTENING.

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

To all whom it may concern:

Bc it known that I, PE'rIn-t McIN'rYnE, of Norwich, State of Connecticut, have invented a new and improved Bedstead-Fastener; and I do hereby declare that the following is a full, clear, and exact description thereof, reference heilig had to the accompanying drawings, and to the figures and letters marked thereon, an'd in p'hich the same parts are indicated by the same letters.

The nature of my invention consists in providing the joints by which bedstcads are put together, or flamed, with metallic fasteners, which-are so coustrncted that the parts can be readily and easily cngaged or disengaged, and be held securely and closely while in position.

To enable others skilled in the art to make and use m y invention, I will proceed to describe its construction and operation. ,4

I construct my fastener in two pieces, A and I, Figure 1, A heilig attached to the side-piece, C, of vthe. bedstead, and B to the post D.

Upon the part A is a projection, or tenon, E, which takes, or enters into the lnortise, or cavity F, in the part B. These parts should be made to titsnug, but not to bind.l

1n the tcnou E a bevellcd notch, G, is formed, hav.- ing a vertical face toward the outer end, as shown.

Into this notch the latch H, attached to the inside of the part B, is made to enter, and thereby retain and hold the parts together, as shown in Figure 2.

The latch H is secured to thc inside of the part B by a pivot, J, as shown in Figure 3, which is a back elevation of the part B.

The latch H is raised out of the notch G by the lever K, attached to the latch, when thc bcdstcad is to be taken apart, and is drawn into and retained in place by the retractor-spriug L, fig. 3.

The lever K has an armature, nl, upon its front side, projecting through the part B, and workingr in the curved slot M, as shown in lig. I. y

This armature takes against the level' N, on the outer face of the part B, as shown in fig. 1, and by the action of this lever upon the armature m, the latch H is disengaged from the notch G.

The level' N has a notch formed in it, so that the armature m, when drawn outward by this level', sha-ll catch in and be held by it, and thereby hold the latch H clear of the notch in the tcnon E; hut upon backing the lever N, the armature 'm willV be disengaged from this notch, and the latch H will immediately drop into. its place.

For the purpose of giving greater strength and stawbility to the joints, I place a pair of coupling-studs, or

` together, by the griping of the inclined faces of the `dovetails, that it is almost impossible to separate them, or to take the bedstead apart without wrench- 'ing such. fastenings ii'oln their places, and as such fastenings have to engage and discngagc bya vertical movement of the sides upon the posts, and which, for the niost part, being varnishcd, such attrition is'thns encountered that the parts are seldom put home to their proper places. All these ditliculties arefcomplctely obvviated by the use ofvmy improvement, as,

the tenon enters directly into the nfortise,withont any binding of the learingsnrface, or any vertical rubbing of the end shoulders against the face of the posts, the parts being instantly and firmly secured together by the latches, and as instantly and easily disengaged when required. j

The fastening herein described I hafepractically tested; but I do not wish to confine myself to the exact details of construction here shown, but claim the -right, under this patent, to alter or vary the same, as

may be considered advisable, to meet the views of purchasers, so long as the principle of the device remains unchanged.

Having thus described my improvement,

What I claim therein as my own invention, and desire to secure by Letters Patent of thcUnit-ed States, is-

A bedstead-fastcner, consisting of a mortise and notched tenon, secured by a latch, II, having an armature, m, attached to its lever K, to take against the outer lever N, by which outer lever the latch H is lifted and retained out of the notch G of the tenon E, when required, constructed and operatingin the manner and for the purpose substantially as described.
