IMPROVEMENT IN ROLLED STEEL PLATES FOR MAKING CULTIVATOR-TEETH.
`Specification forming part of Letters Patent No. 119,419, dated September 26, 1871.
\ To all whom #may concern:
Be it known that we, WILLIAM W. SKINNER and DAVID D. SKI'NNER, of Des Moines, in the side, as hereinafter described.
Our drawing shows in perspective a plate or bar, a blank for a eultivatorshovel, and a finished cultivator-shovel.
Figurel is the plate or bar. a a represent the short swell on the top and edge of the left side;
c c, the short swell on the top and edge of the right side; and b b, the wide swell on the top and center. vrlhe thinnest part of the plate is at the points marked d d. We usually make our plate or bar about live inches wide and one-third of an inch thick at the swells and one-fth of an inch at the thinnest points; but the width and thickness and length may be varied as desired.
Fig. 2 is a blank for a cultivator-shovel cut from the end of our plate. The corners are cut away at the lower end or point.
indicate how it may be drawn out into a perfect shovel.
Fig. 3 is a finished cultivator-shovel. f represents the point drawn or forged from the wide Acenter swell b b. g g represent curved points or enlargements at the sides.
These are drawn or The dotted linesl forged from the short swells on the sides. The points f and g g are worn most in the use of a cultivator-shovel.
rlhe advantage of having blanks with swells and more metal to supply the wear and waste at these points is obvious. It is also an advantage to have the shovel widened at the points gg where the cutting-edge begins, and for this purpose it is a great advantage to have the plate and blank enlarged at the sides, as described. It is also an advantage to have the point f elongated and strengthened; for this purpose the wide swell :in the center of the plate and blank is provided. By having plates formed under rollers or dies, in the shape set forth, there will be a saving of materia-l and great saving of labor in the production of cultivator-shovels such as we have described and generally use.
We are aware that a steel plate is made and patented with a swell in the center, from which blanks are cut for cultivator-shovels; but the shovels we have described and which we use and prefer cannot be made from it without waste of time and material.
prov-ement.
We claim as our invention- The improved steel plate, as described, and for the purposes specified.
