either in a lateral or a vertical direction, and

at the same time to hold the end of the beam measurably rigid.

The nature `of the invention consists of a coupling for connecting the plow-beam to the4 axle of the carriage to which it is attached, which coupling consists of two metallic straps, fastened by bolts, respectively, to the top and bottom ofthe plow-beam, with a swivel-piece connected to the front ends of the said straps by means of a vertical bolt passing through the said straps and swivelpiece, so as to allow the latter a rotating movement on its assembling-bolt, for the purpose of a lateral adjustment. The swivel-piece has serrations on its back edge, by means of which a couplinglink is adj usted and attached to it at dili'erent elevations, as required, and to the front end of this coupling-link is attached a tubular axle, so as to have as much vertical motion about this connection as required.

These couplings are adaptable to any form of plows, but are especially desirable for use on cultivator-plows', where two plows of any form are worked together, the construction ofthe couplings permitting the plows to be easily set at any required distance apart.

The invention Will be readily understood by reference to the accompanying drawings, of which- Figure I is a side elevation of a portion of the end of one plow-beam, with the improved coupling attached to it. Fig. 1I is a plan of the same. Fig. III is a longitudinal sectional elevation of the coupling and its attachments. Fig. IV is a plan of the connectinglink.

The plow-beam A has two metallic straps, B B', secured to its front end by means of the through-bolts a. The strap B is placed on top of the plow-beam, and the strap B on the bottom of the said beam, so that the distance between these plates will be equal to the vertical depth of the plow-beam. Between the front ends of these straps, and titting in snugly between them, will be placed the swivel-piece C, through the vertical axis of which, and through the ends of the straps B B', the bolt a will pass, so as to assemble these parts together, and as the said bolt a is round on the part of it which passes through the piece C, the said swivel-piece will be free to turn laterally on this bolt, for the purpose of lateral adjustment of the parts while in use, as will be required when the plow or ploWs pass over uneven surfaces. The back face of the swivel-piece has several notches, c, at different heights, each of which notches is a segment of a circle, fitted to the peripheryr of the lateral assembling-bolt c. The connecting-link D, at its rear end, is fitted to embrace the swivel (l, and is attached thereto by means of the transverse bolt c. In assembling these parts together the bolt c is placed in either of the notches o, as desired, so as to make the plow run deep or shallowin the usual manner. The front end of the link D is attached to the tubular piece E by means of the clamping-strap F that embraces the said tubular piece, and is secured in place by the nuts f f that screw down on top ofthe link D, the two ends of the strap F passing up through the said link, so as to receive the nuts above the top face of the same. The tube E is made to surround the rod Gr that forms the axle of the carriage, and this tube is allowed a rotating motion on the said axle, for the purpose of permitting a free vertical adjustment of the parts While in use, so as to accommodate the movement of the plows in passing over the asperities of the ground.

When two or more plows are used, these couplings are decidedly advantageous, as the plows can so readily be set at any required distance apart by` simply loosening the nuts axle-,piece E 'by means of the screw-strap vF, Jj', and moving thecoupling -to the position as describeda'nd setforth.
