GRADING-"PLOW.

SPECIFICATION forming part of Letters Patent No. 705,155, dated July 22, 1902. Application filed October 18, 1901. Serial No. 79,106. (No model.)

To aZZ whom it may concern:

Be it known that I,J0HN SowoRDs, a citizen of the United States,residing atDenver,in the county of Worth and State of Missouri, have invented certain new and useful Improvements in Grading-Flows and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to plows,which while useful for all of the various purposes for which such an instrument is usually found desirable will be found especially advantageous for grading roadways and other similar work.

The object of my invention is to provide a grading-plow by means of which the work of throwing the soil toward the center of the road and leaving the surface thereof smooth will be greatly facilitated.

Other objects and advantages will be made clearly apparent from the following specification,considered in connection with the accompanying drawings, made a part of this application, in which- Figure 1 illustrates my invention complete ready for use. Fig. 2 is a detail in perspec tive showing the regulating-lever separated from the other parts.

In order to conveniently designate the elements of my invention and cooperating accessories, numerals will be employed, of which 1 indicates the beam of the plow,which may be formed in the usual or any preferred way,as with the enlarged rear end 2, the forward end thereof being provided with any preferred form of clevis 3,whereby the team or teams designed to draw the plowover the ground may be attached.

My improved plow is provided in substantially the usual manner with the share i c,preferably provided with the oolter 5 and the moldboard 6, and is also provided with a suitable form of seat 7, adapted to accommodate the operator. A suitable platform is also provided below the seat upon each side of the section 2 to accommodate the feet of the operator, as indicated by the numerals 8 and 9, therebyproviding convenientaccommodation for the driver. The moldboard may be reinforced and sustained in its operative position by suitable braces,as indicated by the numeral10, and in order that the cutting depth of the plow may be reliably controlled I provide the regulating-arm 11, which in this instance will be seen to be formed of a continuous piece of suitable material, as by bonding a rod or heavy pipe in the form presented in Fig. 2 and indicated by dotted lines in Fig. 1. The regulating-arm 11 may be integrally formed with the controlling-lever 12 or said lever may be otherwise attached to said bar, as will be obvious.

At a convenient point upon the rear end of the beam 1 I secure in any preferred way the segmental rack-bar13, the teeth of which are designed to cooperate with the detent 14:, carried by the lever 12, said detent being readily controlled by the auxiliary pivoted lever 15, carried by the lever 12, at a convenient point to be grasped by the operator.

Designed to cooperate with the controlling bar 11 is the gage-runner 16, properly secured to the head or lower end 17 of the shaft 18, which latter is rotatably mounted in a suitable aperture provided in the forward end of the beam, as indicated in Fig. 1, it being understood that said shaft 18 is longitudinally movable as well as rotatable. The upper end 18 is passed loosely through a suitable aperture provided in the forward end of the lever 19 and is held against casually slipping through said aperture, as by the key 20 or other preferred means. By thus mounting the shaft 18 in an aperture provided in the lever 19 it is obvious that said shaft is left free to rotate, but is prevented from having a longitudinal movement by the position of said lever. The lever 19, however, is rendered adjustable by mounting the same upon the lug or journal 21, carried upon the upper ends of the bracket 22, the latter being bolted or otherwise secured to the contiguous part of the plow-beam, it being understood that the lower end of the aperture in the lever 19, adapted to receive the lug or journal 21, is slightly enlarged to permit the ends of said lever to be freely raised and lowered suf ficiently to operate the shaft 18. The free end of the lever is provided with a handle, as indicated by the numeral 23. The free end of the lever 19 may, therefore, be readily disposed in an adjusted position, where it may be reliably secured by passing the same into ICQ any one of a series of notches 24, formed upon the contiguous edge of the standard 25, the latter being firmly secured to the upper side of the beam at a convenient point thereon.

The gage-runner 16 is adapted to perform a twofold office inasmuch as it may be dis posed so that said gage runner or blade will ride over the surface of the ground and will hold the forward end of the beam at the desired height, the position of the gage-runner being regulated in the manner above set forth by means of the standard 25, and it is therefore clear that the forward end of the beam may be readily disposed relatively to the surface of the ground. Another use to which the gage-runner 16 may be placed is that it may be turned so as to occupy an oblique angle with respect tothe plane of the beam and secured in such position by passing a pin through the aperture 26, extending through the shaft 18, and the forward end of the lever 19. When the gage-runner 16 is employed for the purpose of regulating the height of the beam from the surface of the ground, no pin is necessary in the aperture 26; but should it become desirable the lower end of the gagerunner may be turned slightly inward, when the single transverse aperture provided in the shaft 18 will be brought into registration with the aperture 6 in the end of the lever 19, and-a'pin can thus be inserted in said registering apertures, so as to hold the shaft in said adjusted position. Inasmuch as but one adjustment, as described, is necessary only one hole in the shaft 18 will be required for this purpose. By thus disposing the gagerunner obliquely with respect to the beam and sharpening the forward edge thereof it is obvious that it will act as a colter and will cut the line of the furrow and sever any roots or the like in advance of the colter 5, thereby enabling the colter to more reliably perform its oflice.

The curved bar 11, it is obvious, may be disposed at any preferred height by a proper adjustment of the lever 12 with respect to the rack-bar 13, inasmuch as said bar is designed to bear upon or engage the contiguous unplowed surface of the soil, which is usually found sufficiently firm to sustain the pressure placed upon said bar by the plow, thereby holding the plow so that it will take into the soil to the proper depth or extent desired.

My improved plow and grader may be formed of any preferred material and made of any size deemed most suitable to meet all the requirements of such an instrument, and while I have described the preferred construction and combination of elements deemed necessary in materializing my invention it will be understood that I desire to comprehend in this application all substantial equivalents and substitutes as may be considered to fall fairly within the scope and purview of my invention.

Having thus fully described the construction and operation of my improved grader, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described combined plow and grader comprising a suitable beam provided with a share and moldboard and a cooperating colter, a suitable seat secured to the beam, in combination with a regulating-bar 11 provided with the adj usting-lever 12 having means to hold said lever in the desired position and an auxiliary regulating gagerunner 16 and a lever 19 cooperating therewith whereby said gage-runner may be adjusted as desired all combined substantially in the manner specified and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN SOWORDS.
