HARRY WIARD, OF SYRACUSE, NEW YORK.

PLOW -BEAM.

SPECIFICATION forming part of Letters Patent No. 229,216, dated June 22, 1880.

Application filed April 12, 1880.

To all whom it'may concern:

Be it known that I, HARRY WIARD, of the city of Syracuse, Onondaga county, State of New York, have invented certain new and useful Improvements in Plow'Beams, of which the following is a description.

Myinvention relates to wrought-metal plowbeams, formed ineterably of steel, substantially as hereinafter described, and swaged into form, as clearly illustrated in the drawings; also in being formed without welding or being highly heated, or otherwise strained or injured in the process of manufacture, and at a cost so small as to render its use practicable, and which is strong and elastic.

I attain these objects in the manner described, and illustrated in the accompanying drawings, in which- Figure .1. is a rolled bar of steel, formed with a web, a, and two flanges, b b; Fig. 2, the same, with a triangular piece cutout of it at the rear end and the flanges clipped and swaged into form for the front end of the beam; Fig. 3, front heading-piece of the beam detached; Fig. 4, the beam with the rear end bent into form and the heading-piece affixed.

The construction is as follows: I take a straight rolled bar, Fig. 1, cut to the proper length for a beam,and cutfrom the web a, at the rear end, the acute-triangular piece at c. The bar then receives a light heat, just sufficient to readily swage the parts into form, with the downward curve as shown in Fig. 4, but without welding. The rear ends of the flanges b have a hole punched in them, through which a bolt, .1 passes.

This gives a suflicient clas- (No model.)

ticity to the beam to relieve it from the shocks incident to a rigid beam. The front end of the beam is clipped into the form shown in Fig. 2, with the end of the web a projecting beyond the flanges, and a hole, cl, is punched through the web. A forked head-piece of malleable metal, Fig. 3, is slipped over the web, andfa thimble passes through a hole in its ends and the hole in the web at d, by which they are securely fastened together, as seen in Fig. 4. The front end of the web enters a recess in the head-piece, as shown by the dotted lines, and the beam is finished. A hole, a, is formed in the web to affix thejointer-standard, and others, where needed for other attachments.

Having thus fully described my improved wrought-steel plow-beam, I claiml. The plow-beam a, made without welding from a bar of wrought metal, with branches 1) b, formed by clipping from the rear end a tri' angular piece ofthe web of the bar, the branches being bent, as shown, to form an elastic beam at its attachment to the plow, substantially as described.

2. The wrought-metal plow-beam it, formed from a flanged bar having its front end form ed as shown and described, in combination with the malleable head-piece f, fitted thereto, as set forth.

3. The heading-piece f, in combination with the flanged beam to, for forming the front end thereof, substantially as shown and described.
