vPRovi-:MENT IN PLows.

Specification forming part of Letters Patent dated August 17, 1832.

To all whom it may concern:

Be it known that I, JOHN VEAVER, of the borough of Brownsville, in Fayette county, Pennsylvania, have invented a new and useful Improvement in Plows, which is applicable to the single and also to the double or hillside plow; and I do hereby declare that the followingis a full and exact description of the construction and operation ot' the said plow as invented or improved by me, viz:

The leading principle consists in a means of moving the beam of the plow on the sheth or frame to which the shoe, share, and colter are attached by means of an iron bolt passing up through the beam from a forward projection of the top of the front sheth. On the top of the hindsheth is an iron cap or cam. Through this is a horizontal mortise, and through this mortise is another mortise transversely. The former mortise receives astrong strap or light bar 'of iron extending from the' hind end of the beam, and the mortise, being longer than the bar is broad, permits the beam to play so as to give the plow more or less land at pleasure. Then there is a screw-bolt comes up through the other mortise, (the head coming square through the aforesaid bar to prevent the bolt turning when screwed.) The nut of said screwbolt being drawn on the joint which lies on the regulating-cap, through which the bolt passes, permits thejoint and bar to play horizontally. This joint has one end bent down over the regulating-cap. Through this end passes a tempering-screw, which abnts up against the cap or cam, by means of which the end of the beam is made to have more or less angle. The ends of the cap are oval horizontally, so that the screw in the plate will play round the oval endsof the cap orcam. To saidjoint,which lies'on the regulating-cap and works vertically, is a rod fastened, which reaches to the mold-board, on which rod is another .tempering-screw, which will lengthen or shorten the rod and give the mold-board a position to suit hills of different grades. There is another rod or trace, which works on a bolt near the lower end of the hid sheth and reaches to the center of the mold-board, and acts as a brace to support the hind end of the same. On the top of the front sheth is a plate with a hole in the center, on wlich another plate let into the beam works. On the lower plate is a eircular projeetion downward. This projection works circularly against the back edge of the front sheth and takes the strain off the bolt that holds down the beam. The sheths of which mention have been made are two uprights attached to the landside, on whicl the beam rests and plays, as before desciibed. The colter at the top has a horizontal projection backward, and is bolted to a forward projection of the forward sheth, by which the beam can play on the top of the colter. The colter forms a trace and takes the strain off the pivots or gudgeons on which the mold-board, shoe, and share turn.

The shoe, share, and mold-board for the hillside-plow are connected with each other, and are so formed that either edge will answer to be down. The under side of the shoe is round longitudinally,each end terminating in a point or gudgeon, the front gudgeon working in a hole in the front part ot' the front sheth, near the bottom. O these gudgeons the noldboard, shoe, and share revolve, and are exactly in the same position for plowing on the one side of the plow as the other. VVhen the irons are to be turned fron one side of the plow to the other, take the hook that forms part of the joint out of the e ve in the mold-board, turn it round horizontally, and hook it into the eye on the other side ot' the' mold-board, and the plow is complete.

Now, it is well known to all men of experience that a plow will plow well in light soil and will not in stil' soil or clayey land, the cause of which your petitioner, after much study, has discovered, is the different pressure of different soils on the mold-board. Now, by the moving beam this difficulty is entirely obviated, as it is evident that by moving the beam the pressure of the furrow on the mold-board ean be so regulated that a plow will work equally well in every kind of soil, for by altering the angle of the beam with the furrow the lever-power of the beam and mold-board may be made exactly equal. Oonsequently the plow will run steady in all kinds of soil. This he thinks the greatest discovery ever made in that useful implement, as it is impossible to make a plow that will Work equally well in all kinds of land, if the beam is stationary. The moving beam will have an equal efl'ect on the single and double or hillside plow.

What vour petitioner claims as new and as his own invention, discovery, or improvements in plows, and for the use of which he petitions for an exclusive privilege, is as follo\vs,viz:

1. The moving beam as applied to single ad hillside plows.

2. The double shoth.

3. The shoe.

v4. The pivot passing; through the shoe on Which the irons turns.

5. The manner in which the colteris attached to the sheth.

i 6. The plate on the under side'of the beam, which takes the stress ofi'the bolt which comes up through the beam, and on which the beam moves. v

7. The regulating cap or cam. 8. Thejoint or hinge with two temperingscrews, one for regulating the band and thel JOHN WEAVER.
