IMPROVEMENT IN HARVES'IER-PITMEN.

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

To all whom 'it may concem:

Be it known that I, CHARLES E -ROPER, of Canton, in the county of Stark, and in the State of Ohio,

have invented certain new and useful Improvements in Pitmen; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and general arrangement of a pitman, for reapers and mowers, and other machines requiring motion either in or out of a direct line;

In order to enable othersskilledin the art to which my invention appertains, to make and'use the same, I will now proceed to describe its construction and operation,'referring to the annexeddrawings, which form a part of this specification, and in which Figure 1 is a perspectiveview; A

Figure 2 is avertical of the joint; and

Figure 3, a side view of the tapeiing bolt;

. A represents the end of the knife of a reaper and mower, on which are two lugs, or ears, B B. Between the two cars B B, the ball 0 of a ball-and socket joint is placed, and to obtain the rigidity necessary to a perfect working of said joint, the ball 0 is secured by means of a taper-bolt, D, said bolt passing through the two ears, or lugs, and the ball.

All wear and tear, of the joint are easily overcome, by simplyturning the said taper-bolt D to any desired degree of tightness.

The ball 0 is enclosed in a box, E, composed 01 two pieces formed to fit, or cover the ball, said pieces, or box being confined to their places by a strap, F, passing around the box; and said box E is controlled by an adjusting-screw, G, one end of which is contained in a hollow tube, H, to which the strap F is secured.

The other end of the screw G is made concave, to

-low tube H, and the other in a similar tube, H.

, The hollow tube H has a similar arrangement of adjusting=screw, jam-nut, strap, and box, as described A for the tube H, and marked respectively on the drawing as G, I, F, and E.

The adjusting-centre J is controlled by the adjusting-screws G G, working, in connection with ball-andsocket joint, at both ends of pitman, and by the jamnuts K K, as shown in fig. 1.

By this means, I obtain a pitman whichis adjustable and accommodating to any or all depressions in surface, being oapable of extension or contraction, and being made entirely of gas-pipe and malleable iron, or its equivalent, can be made lighter and at less expense than those now in use.

Having thus fully described my invention,

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

The combination of box E, strap F, tube H, pipe J
