GRADING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 276,583,V dated May 1, 1853 Application filed December 4, 1882. (No modelf) To all whom it may concern Be it known that I, HENRY T. HAYS, of Lexington, in the county of4 Scott and State of Indiana, have invented a new and useful Im- 5 provement in Grading-Machines, which shall be simple in constructiominexpensive in manufacture, and convenient and effective in use.
Similar letters of reference indicate correspondin g parts. 1o The accompanying drawngrepresents a perspective view of my invention.
c represents the scraper-blade, upon the top of which are mounted the two standards b, which are slotted at their upper ends for the 15 vertical adjustment of the handles c. 1n between the upper ends ofthe standards is bolted the plate h, which has its ends turned at right angles, and through these ends, the standards, and the handles are passed tbe clamping-bolts Secured to the standards at their lower lends,and to the handles, are the braces e, which serve to draw the scraper-blade along and prevent it from giving backward. The handles c are 25 extended forward and form both handles and beams, and are loosely fastened at their front ends to the bolster-coupling f, which is intended to be attached to a barrow by means of the bolt y. Secured to this bolster are the two flat springs g, which keep the blade forced 5o constantly downward, so as to sink through the dirt whichV has been loosened by the harrow, which is drawn'along in front.
The barrow or cultivator for loosening the earthis nothere shown, as it forms no part 35 of my invention.
Having thus described my invention1 I claimt i 1. In a grading-machine, the combination of the scraper-blade a, the standards b, combined 4o Witnesses:
