Improved Yoke for Oxen.

This yoke is constructed with sliding blocks attached to the under side of the beam of the yoke, near each end, and each sliding block is attached to the beam by bolts which pass through mortises so that the blocks may be made to slide occasionally to the right or left. To these blocks are attached the bows, the position of which are adjusted by gauge screws; and by the sliding of the blocks, the distance of the oxen from each other may be regulated. The middle of the yoke is furnished with a draught staple or eye-bolt which is moveable and regulated by a hand screw at the top, whereby the pitch of the draught it regulated. Invented by David Chappel, and entered at the Patent Office, Sept. 3d.
