PATENT OFFICE.
SAME PLACE.
IMPROVEMENT IN PLOWSHARES.
Specification forming part of Letters Patent No. 110,860, dated January 10, 1871.
.1'0. all whom it may concern.-
Be it known that I, JOHN LANE, of Chicago, State of Illinois, have invented certain Improvements in Plowshares, of which the following is aspecificat-ion.
My invention consists in making a plowshare having a thick flange, a thick end, and a thin body or main portion made by first making a share-blank having a thick end and afterward welding on a. separate piecefor theflange onto the underside of the thick end of the share-blank. e Referring to the drawings, Figure 1 gives a view of myimproved plowshare. Fig. 2gives a view of the share-blank before the flange is welded on, and from which I make my improved plowshare. Fig. 3 gives aview of the plate of wrought metal, havinga longitudinal thick center, which illustrates my approved method of making-the share-blank.
Like letters in the different figures refer to like parts.
a is the flange. b is the thick end of the plowshare, and c is the body or main portion of the share. Dotted line .70 shows the meeting-line of-the thick, 11, and the thin, 0, portion of the share. Dotted line 20 shows the place where the flange a is welded, to the thick end b of the share-blank forming my improved plowshare;
The share;blank; is cut from the metal plate in such a manner that the thick portion of the blank-is from thethick portion of the plate, while the thin portion of the share-blank is from the thinportionof the plate. Wroughtmetal plate having a longitudinal thick margin, or having thick places in it, may be used The share is made by heating the blank to point of the share, while bolts at fore or after the share is formed to shape.
The landside-bar of the plow extends under the share of the flange a, givingsuprort to the a k secure and hold the share 'in its proper position on the plow.
The point and forward end of the share receives' the brunt of wear, and when thin wears out, quick, and is very liable to bend and break when meeting obstructions.
My improved plowshare, being extra thick at the point and forward end and stiffened by the flange a, is strong'and lasting, and for the flange a, I use a softer metal than I do for the share-blank, which wears the faster by being softer and provides for a self-sharpening point by wear. v
I am aware that plowshares having a thick forward. end welded to a landside bar have been usedfsnch I do not claim, and I do not claim, broadly, a plowshare having a flange.
Having thus set forth myinvention, I claim- A plowshare having a thick flange, a, a thick end, b, and athin' body, a, when made by first making a share-blank having a thick end from one piece of metal and afterward welding thereto the flange a, substantially as and for the purpose set forth.
