JOHN S.' BURTON, OF PARIS, ILLINOIS.

FOLDING JOINT.

SPECIFICATION forming part of Letters Patent No. 266,766, dated October 31, 1882.

Application filed November 26, 1881. Renewed August 17, 1882.

To all whom it may concern Be it known that I, JOHN S. BURTON, a citizen of the United States, residentat Paris, in the county of Edgar and State of Illinois, have invented a new and valuable Improvement in Folding Joints; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of the same, referencebeing had to the annexed drawings, making apart of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my device. Fig. 2 is a sectional view. Fig. 3 is a view showing the device folded up, and Fig.4 is an end View.

This invention has relation to foldingjoints for the legs or arms of cots, vbenches, or other articles when economy of space in storage or transportation is desirable; and the invention consists in the construction and novel arrangement of a curved connecting-brace, a pivoted loop or stirrup lock, and a socket, all as hereinafter set forth, and pointed out in the claim.

In the accompanying drawings, the letter A designates the rail or other portionof the body of an article to which the leg or other part B is to be connected in a folding manner.

0 represents a curvedbrace, usually made of malleable iron. This brace is pivoted by its upper end to the rail or body A, and by its lower end to the leg. At its lower end the brace is formed with a convex curvature or bearing, 01.

E represents a socket, which is preferably made of malleable iron, anti is secured to the (N0 model.)

rail at the proper distance from the upper end of the brace to receive the head of the leg.

F indicates a loop or stirrup-strap, the upper end of which is pivoted to the rail or body near the socket. The brace (l is designed to pass through the loop or stirrupgat the lower end of the strap, and the length of said strap is sufficient to allow the loop or stirrup to engage the curved bearing of the brace tightly, when the parts are set up, the head of the leg being in the socket. The brace is then in an oblique position, and it is rigidly held in place by the loop or stirrup-strap, which forms a lock. By the same means the head of the leg or arm, as the case may be, is held in firm engagement with the socket.

When it is desired to fold the leg the looking loop or stirrup is slipped from the curved bearing portion of the brace toward its middle part, allowing the brace to move on its upper pivot and the head of the part B to be detached from the socket.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

In a foldingjoint, the combination, with the part A and leg B, of the socket E, curved brace G, and pivoted loop or stirrup lock F, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN SANFORD BURTON.
