GEORGE HOPKINS SMITH, OE DES MOINES, IOWA.
IMPRQVEli/IENT IN SHOVEL-PLOWS.
Specification forming part of Letters Patent No. 125,491, dated April 9, 1872.
Specilication describing a new and useful Improvement in Shovel-Flows, invented by GEORGE HOPKINS SMITH, of DesnMoineS, in the county of Polk and State ot' Iowa.
Figure 1 is a front view of my improved shovel-plow. Fig. 2 is' an edge view of the saine. Fig. 3 is a rear view ot' the Same. Fig. 4 is a detail cross-section ofthe same taken through the line x m, Fig. 3. Fig. 5 is a detail cross-section of the Same taken through the line y y,
Fig. 3.
Bly invention has for its object to furnish an improved cast shovel-plow for cultivators, which shall be so' made as to possess the requisite strength While leaving its forwardside or.
the plow-seat, by which the plow is secured to the plow-standard. Upon the rear sides of the side edges are formed short projections, ribs, or thickenin gs, C, extendingfor such a. distance as may be necessary for throwing out a full corner and giving the requisite strength to the shovel, the. upper parts ofthe side edges., where so much strength is not required, being made lighter.
The Shovels may be cast of any metal that will give a good tough cutting-edge and a strong back, and will take the highest possible temper upon the front. Cast-,steel fronts east upon Bessemer-steel backs, in cast-iron molds, will make the best shovels.
Having thus described my invention, I claim as new 4and. desire to secure by Letters Patent The shovelplowshare A, having cent-ral rib B and side ribs O C arranged thereon, as and for the purpose described.
