iMPnovED KNUcKLE-JOINT.

Speciii cation forming part of Letters Patent No. 52,90S, dated February 27, 1866.

To all whom t may concern:

Be it known that I, Sir/[EON N. TAYLOR, ot Horicon, in the county ot' Dodge and State of. Wisconsin, have inveu teda new and Improved Knuckle-Joint for Connecting the Tuinblingf Rods of Thrashing-h/lachines and Shafting of other Machinery, and I do hereby declare` that the following is a full, clear, and exact description thereof, which will enable others .skilled in the art to fully understand and use the saine, reference being had to the accom-` panying drawings, 'making a part of this specitication, in which- A' Figure l represents a longitudinal vertical section of my invention, taken in the line a: a, Fig. 2; Fig. 2, a transverse vertical section ofthe same, taken in the line y y, Fig. l.

Similar letters of reference indicate like parts.

This invention relates to a new and 1in. proved coupling for connecting together the tumbling-rods of thrashing-inachines and the shaftin g of other machinery which require to be placed in an oblique position relatively with each other. Q g

The invention is an improvement on a knuckle-joint for which ALetters Patent were granted to me bearing date l `ebruaryl6,1864; and itconsistsin constructing the parts in such` a manner that the tumbling-rods may be l turned in either direction, the original device being capable of turning in one direction only.,

A represents a socket which externally may be of cylindrical form, and is attached to onev end of one of the tumbliiiigrods or shaft B. This socket is provided internally with a series of longitudinal ribs or shoulders a, which are formed by making a series of curved recesses. or grooves, b, in the socket, the 4shoulders c. extending the whole length of the interior of! the socket A. The inner edges of the ribs or. shoulders may be slightly curved, very muclnv less however than the recesses or grooves b.

C represents a head, which is attached to one end of the other tumbling-rod or shaft D. This head has a series of ribs or projections, o, on its periphery, said projections being formed by making curved recesses d in the periphery of the head, said projections being curved in a longitudinal direction and corresponding to the curvature of the recesses or grooves b, while the spaces betweenqth'e projections o are also curved, the head Cv being of spherical forni or approaching said form.

The ribs or shoulders a havea radial position within theV socket A, and both sides lof the projections c of the .head C have a radial position with the shaft D.

The head C is of such diameter at its largest central part that it may lit into the socket A, and as the other parts of the head are curved inward at both sides ot' the center, or toward each end, it will be seen that the two shafts `B D may be placed in line or in an oblique position relatively with each other and rotated p in either direction, the socket and head t'orming the connection between the two shafts, the sides of the shoulders aand projections c being in contact. This coupling possesses all the advantages of the patented one hitherto alluded to, besides the advantage of the tumbling-rods being turned in either direction, a result due to the construction or formation ot' the ribs or shoulders a and the projections c, the latter having both sides radial with the head C.

I claim as new and desire to secure by Letters Patent- The constructing or forming ot' the head C of the shaft l) with ribs or projections c, both sides of which have a radial position with head, in combination with the longitudinal ribs or shoulders a. of the socket A, l,which are formed by making a series of curved recesses or grooves in the socket, the shoulders a extending the whole length of the interior of the socket A, to admit of the tumbling-rods B D being turned in either directionthat is to say, to Ithe right or left, as may be desired.

SIMEON N. TAYLOR.
