UNITED STATES PATENT OFFICE,
IMPROVEMENT IN PLOWSHARES.
Specification forming part of Letters Patent No. 35,819, dated July 8, 1862.
To all whom it may concem:
Be it known that I, JOHN S. HALL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Plowshares; and I do hereby declare the following to be a full, clear, and exact description of the construction of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 represents a view of the blank out of which the plowshare is made. Fig. 2 represents the partially-made plowshare, and Fig. 3 represents the plowshare completed.
The purpose and object-of my invention is to make a plowshare that has a cutter and bladeupon it out of a single piece of plate steel or iron,-to avoid welding, as well as to have entire uniformity of shape, and to make the shares strong and at a reduced cost.
To enable others skilled in the art to make and use myinvention, I will proceed to describe the same with reference to the drawings.
- I first stamp or cut out a blank having a stem, A, and two branches, B O. The branch B is then laid into a proper-shaped die, andtapered and drawn out intothe form shownin Fig. 2, and atthe same timeashoulderis formed at theline a. The stem A has one of its edges drawn down, as at b, so as to form a cuttingedge. This may be done on an ordinary anvil. The edge 0 of the branch B is brought to a thin edge in the diein which it is laid or drawn. The blank being thus prepared, as shown in Fig. 2, the stem A up to t-he square shoulder a is clamped between proper-shaped dies, and
the branch B is bent down at right angles, or nearly so, to the stem, making a perfectly square corner where the shoulder a was, and thus finishingthe plowshare. The branch 0 forms the point of the share, the branch B makes the horizontal blade, and the stem A forms the vertical cutting-edge of the share. The shape of the partially-drawn blank, as shown at Fig. 2, and its shoulder at a, are more distinctly shown by a section through said figure at the line a: a0 thereon. The making of the shoulder a on the blank is what enables me to form a square corner at that point on the finished plowshare.
Having thus fully described my invention, what I claim is-- Drawing and bending a plowshare out of a single piece of steel or iron that shall have a
