WILLARD A. VAN BRUNT, OF HORIOON, WISCONSIN.
MANUFACTURE OF DRILL-SHOES.
SPECIFICATION forming part of Letters Patent No. 499,061, dated June 6, 1893.
Application filed January 1], 1893. Serial No. 458,062. (No model.)
To all whom it may concern:
Be it known that I, WILLARD A. VAN BRUNT, of Horicon, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in the Manufacture of Drill-Shoes; 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 an improvement in the manufacture of shoes for grain drills. Shoes of the class employed by me have usually been made of two plates welded together at their lower edges. With such prior devices, the meeting edges of the plates, or where said plates are welded together, have been very slight. That is to say,the amount of surface of one plate exposed to the other plate where said plates are welded together has been very small, and thus the solidity and durability of the shoes have been greatly impaired.
To avoid this defect and to provide simple and efficient means whereby to produce a shoe with a rear thickened portion without the use of a supplemental plate between the plates composing the shoe, is the object of my invention.
With this object in view the invention consists in certain novel steps in the process and in certain features of construction of a blank, whereby to produce a blank for a shoe for a grain drill, as hereinafterset forth and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view of the blank from which the shoe is made. Fig. 2 is an end view; and Figs. 3, 4, 5, 6, 7 and 8 are views of modifications.
A represents the blank or plate from which my improved shoe is made. The edges of the blank are beveled as at a, a, and at the center of the blank two enlargements or thickened portions 1), b are made, said enlargements or thickened portions having inclined faces 0. A portion of the plate or blank A of sufficient length for a shoe is then cut OE and the blank separated or cut apart at the center, on the line cl. Each part of the blank is now severed diagonally on the line 6, said line extending from the enlargement or thickened portion 12 at one end of the blank to a point inwardly removed from the outer edge of the blank at its other end,thus producing two plates B, C. The plates B, C, are then cut to the proper shape, preferably about the shape shown in Figs. 5 and 6. The beveled edge a of the plate B is then placed against the inclined face a of the thickened portion 1) of the plate 0 and the two are then welded together, producing a V- shaped shoe (in cross section) havingathickened portion between the plates composing the shoe in proximity to the cutting edge of the shoe and extending from the rear toward the forwardend thereof, thus producing wide bearing faces Wheret-he two plates are united. It will be seen that from each plate or blank A, two complete shoes can be produced. The blank may be made by rolling,ha1nmering or in any other suitable manner.
Instead of beveling the edges of the plate B as above described, said plate may be made plain as shown in Figs. 3 and 4, in which the apex of the shoe will have to be sharpened to produce the cutting edge after the plates are welded together.
Instead of providing the plate 0 with the enlarged or thickened portion 5, both plates B and C may be made with such enlargements or thickened portions, as shown in Figs. 5, 6, 7 and 8.
The blank from which these shoes are produced will be upset or otherwise enlarged at diagonally opposite edges as shown in Fig. 7, and then the blank is cut diagonally, as shown in said figure. After properly shaping the plates B, O, the inclined faces of their thickened portions will be placed together and welded.
By making a shoe for a grain drill in the manner above described in connection with all the forms of the invention, a thickened portion will be provided above and in proximity to the cutting edge of the shoe, thus not only strengthening the shoe by the mere fact of having a thickened portion above the cutting edge,-but also providing extended surfaces to be welded together, thus producing a very rigid and substantial shoe.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The herein described method of forming drill shoes consisting in taking a bar of metal with a rib formed thereon, cutting it in two diagonally, and securing the ribbed part to the 1part cut therefrom, substantially as set fort 2. The herein described method of making drill shoes consisting in taking a bar of metal with a rib thereon, cutting a piece diagonally therefrom, reversing said piece and securingit to the ribbed portion of the part from which it was cut, substantially as set forth.
3. The method of producing drill shoes, oonsistingin first beveling the edges of a plate or blank, producing beveled enlargements at I the center of said plate or blank, severing said plate between the beveled enlargements, cutting each section of the plate or blank thus severed, diagonally to produce the two plates of a shoe, and placing the beveled enlargement of one plate against the beveled enlargement of the other plate, and finally welding said plates together at their abutting faces, substantially as set forth.
4. The method of producing drill shoes, consisting in first producing enlargements or thickened portions at the center of a plate of metal, severing the plate between the enlargements or thickened portions and then cutting each section of the plate thus severed, diagonally to produce two plates of a shoe, and securing them together, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscrib- 5 ing witnesses.
