TO Ann WHOM IT MAY CONCERN:

Be it known that I, F. B. MORSE, of New Haven, inthe county of New Haven, and State of Connecticut,

have invented a new Improvement in Stump-Joint for Carriages} and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1,a perspective view of thejoint closed, and in Figfire 2 a. top view of thejoint open. 7 i This invention relates to an improvement in the stump-joint for which Letters Patent were granted to me, July 28, 1868, but is alike applicable to otherjointsin which the two stumps are joined by a tongue and the invention consists in forming notches or an uneven surface upon the meeting-end of one stump, and a corresponding surface upon the other stump, so that, when the joint is open, so that the two ends meet, the irregular surface of one will mesh into the corresponding irregularities of the other, so as to strengthen the joint in that position, and prevent the shackling of the joint.

In orderctothe clear understanding of my invention, I will fully describe the same as illustrated in the accomp'hnying drawings.

Ayis the one ,part, B the othe'ri the two partsjoined by a piece or tongue, 0, to which each part is pivoted at a andrl. v i p In Lmy patent before referred to, which embodies the construction of a joint of these three parts, when the joint is open, as in fig. 2, the back ofthe recess in each partbears against the edge of the piece or tongue 0, as a-guido to bring it to und asa support to sustain it in the proper position. i

By constant use, the parts are liable to more or less wear, and such wcar' would tend to loosen the joint and make it shackly." To avoid this, and to'reliev'e the connection 0, I form n notch,.f, in one part, and a corresponding projection, it, upon the other part, so that, when the two parts are open, as in iig. 2, the projectionon theone part will enter the notch or recess in the other part, and thus serve partially as a guide, and as a chief support for-the two parts in a proper position. i

It will be readily seen, by those acquainted with the n'a nufacture of such articles, that other forms of irregularity upon the end of the joint would produce thesame result. I show theform, as denoted in the drawing, as being very simple, and ot' acheap construction, but do not wish to be understood as confining myself to any particular 'form for the end of the two parts of the joint; but having fully described my invention,

What I claim as new and useful, and desire to secure by Letters Patent, is-

. A stump-joint, consisting of the two parts A and B, hinged together by a connection, 0, pivoted to each ofthe parts, forming the; meeting-ends of the joint, of irregular form, the one corresponding to the other, so as to operate substantially in the manner specified.
