IMPROVEMENT IN PLows.

Specification forming part of Letters Patent No. 61,762, dated February 5, 1567,: Reissue NoLOSS, dated August 25, 18GB.

To all whom it may concern.- strain on the plow is not so great as when it Be it known that we, M. RICHARDS and J. I is constructed according to the present plans. VANDnG-Riirr, of Princeton, in the county of To enable others skilled in the art to make Bureau, in the State of Illinois, have invented and use our plow, we have marked correa new and useful Improvement in Flows, and sponding parts with similar letters, and will we do hereby declare that the following is a now give a detailed description. full and exact description thereof, reference AA represent the landside and mold-board being had to the accompanying drawings, and of a common plow. to the letters of reference marked thereon, I B shows the foot-support or brace, kwhich is making a part of this specification, in which used for the double purpose of supporting' the Figure l is a perspective representation of lower end of the beam C 4and strengthening our improved plow,- Fig. 2, a plan view of the the landside A and mold-board A', to which. same; Fig. 3, a section of the beam, and also it is attached, by bolts or otherwise, in a suba section of the arm which supports the same, stantial manner, and has a vertical hole near and the devices which hold the beam after it the middle and inv a convenient place for rehas been turned, so as to cut a furrow of the ceiving a pivot made on the lower end of the desired Width. rear part of the beam C.

The nature of our invention consists, iirst, D is the arm supporting the beam. C near in the use of a double-concave wrought-iron the top of the mold-board A. This arm has beam, pivoted to the plow, for which we claim an elbow, which passes down and against the the advantage of lightness and strength, not cutter-edge ofthe mold-board A, near its top, nowsecured by theuse of other beams,whether i to which it is rigidly attached, as seen at E, cast or wrought, and 011e which maybe turned Fig. l. on the pivot, and thus set the plow to run to t F represents the clamp which holds the and from the land without the use of a clevis; beam C iirmly against the arm D. It will be second, in the arrangement of a foot-support seen at Fig. 3 that the beam C passes through for staying the landside and mold-board, and the clamp F and has the plugs 7L iitted in both providing a permanent pivot-seat for the rear sides of the concave beam. These plugs are end of the beam to rest upon, third, in proimportant in not only assisting to hold the riding an arm extending out from the moldbealn, but allow it to be swung such adistance hoard for the purpose ol providing additional to or from the land as will regulate the width support for the beam, and clamping it iirmly of furrow to be turned. in position after it has been set to gage the In order to give a correct understanding of plow to eut the desired width of furrow; the benefit of this device, we will refer to the fourth, in the use of suitable fillings or plugs position of the beam C at Fig. 2. This beam fitted to the concave sides of the plowbeam, in this figure is set to run the plow so as to cut in order that the required pressure may be had I a wide furrow; but the dotted lines O show against its sides in'order to hold it in posihow the beam C may be moved toward the tion when once set. landsideA, so as to cut a furrow of less width.

rlhe advantage to be gained by the use of In order to accomplish this, the bolts I, seour invention is, first, abeam can be made curing the clamp F, must be loosened, so that of wrought-iron, rolled the required shape, l the beam can be turned as far as desired, after which will be much lighter than those now in which the nuts can be tightened securely, and use, and yet possess all of the strength rethe beam C will be properly set for the required'ior the purpose desired, and the beam quired gage.

The power can be applied at the end oi' board being securely fastened together, the the beam C at .T in the usual manner.
