HENRY G. BUTLER, OF DANVILLE, ILLINOIS, ASSIGNOR OF ONE-HALF TO \VILLIAM BUTLER, OF DANVILLE, ILLINOIS.
SHALE-ROCK PLOW.
SPECIFICATION forming part of Letters Patent No. 696,898, dated April 1, 1902.
Application filed February 26, 1901- Serial No. 48,883. (No model.)
To all whom it may concern.-
Be it known that I, HENRY G. BUTLER, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented a new and useful Improvement in Shale-Rock Plows, of which the following is a specification.
My invention relates to improvements in plowing apparatus for use more especially in making furrows in hard material-such as frozen ground, soapstone, slate, shale rock, or the like.and in stripping off coal-beds.
My object is to provide a plowing apparatus or device of novel and improved construction which adapts it to perform heavy work, such as referred to, in a manner more economical and satisfactory than by blasting and other means hitherto employed.
Referring to the drawings, Figure 1 shows my improved device in side elevation. Fig. 2 is a rear elevation; Fig. 3, a top plan View; Fig. 4, an enlarged broken section taken on line 4 of Fig. 3, and Fig. 5 an enlarged broken perspective view of a furrowing blade of modified form.
The plowing device is necessarily large and heavy, and although the size and weight would depend largely upon the character of work to be performed it may weigh in practice up to twenty tons or more. It comprises a body or platform portion A, preferably of solid metal, having asmooth under surface a, provided with a beveled, inclined, or rounded forward end b. On the forward portion of the platform midway between its sides is an upright plate B, firmly secured in place and braced by means of the upright cross-plate O. In the forward part of the plate B are holes 0, and on the rear upper part thereof is asheave D. Extending through the platform in the positions shown are openings d, e, and f. Thevrear wall of each of said openings is formed with rack-teeth g, and the opposite or front walls thereof are inclined, as shown at h. The opening (1 is centrally between the sides of the platform, and the opening f is just twice the distance of the opening 6 from the center.
E E are furrowing-blade standards, and E 50 is a scoring-blade standard, all comprising heavy bars of steel or other suitable metal,
provided at their lower ends with forwardprojecting points i. The blade-standards are formed along their rear edges with rack-teeth 7c, and they fit through the openings in the platform, with their teeth in engagement with those of the racks g. The standards may be adjusted in the platform to extend at their points the desired distance below the surface a and are fastened in place by means of wedges Z, which are forced down the inclined walls 71. by means of screws m to clamp the raclesurfaces in engagement.
The device may be raised and lowered to place it in its initial position by means of a suitable derrick, the derrick-rope passing under the sheave D. Draft-chains are fastened at one or more of the openings 0, and the plow is drawn across the ground to be worked by means of a suitable engine. The blade of standard E scores the ground as the plow is'drawn along, and thereafter the blade of standard E is caused to travel in the score or furrow previously made by the blade of standard E The blade of standard E plows 7 5 up and breaks away the material along the edge portion of the ground that is being plowed. The effect of the blades as they are drawn through the ground is to force up the material and raise the device slightly above the natural level of the ground, whereby it bears with all its weight upon the plowed material and crushes and grinds it in a manner to permit of its ready removal by means of a scraper or dredge. If desired, the weight of -8 5 the plow may be increased by placing rock or the like upon the platform A. The standards and blades may be formed all in one piece, as shown in Fig. l, or may consist, as shown in Fig. 5, of a bar to which the shoe or point is secured.
While I prefer to construct the plowing device throughout as shown and described, it may be variously modified in the matter of details of construction without departing from 5 the spirit'of my invention as defined by the claims.
What I claim as new, and desire to secure by Letters Patent, is-
1. A combination plow and crusher comprising a platform having a continuous under crushing-surface adapted to contact with and tween the latter and forming a guide for the movement of the plow.
3. The combination of the platform A,bladestandards E, E E extending through and ad- 3' ustably secured to the platform, plate B, having draft-attaching means'c, secured to the platform, brace-plate O for the plate B, and sheave D on the plate B, substantially as de scribed.
HENRY G. BUTLER. In presence of JAMES P. DANSON, ALBERT DANSON.
