IMPROVEMENT IN PLOW-BEAMS.

Specification forming part of Letters Patent No. 23,024, dated February 22, 1859.

To all whom it may concern:

Be it known that I, JOHNS. HALL, of Manchester, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Iron or Steel Beams for Flows; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents in perspective a plow constructed with one of the beams in question. Fig. 2 represents a vertical cross-section through the beam and a portion of the standard to show how they are braced and united together. Fig. 3 represents a longitudinal horizontal section through the beam.

Similar letters of reference, where they occur in the several figures, denote like parts of the plow in all of them.

My object is to make an iron plow that will be strong, durable, and cheap, and with-a1 light and of easy drat't.

1am fully aware that tubular beams and handles have been proposed in the construc tion of plows and other agricultural implements; but the difficulty of uniting the several parts of the plow to such tubular forms i has rendered them of no available use whatfacilities for uni'ting'the other parts of the plow to it as to make this form of plow-beam very desirable and economical.

To enable others skilled in the art to make and use my invention, I will proceed to describe the samewith reference to the drawings.

A. represents a plow, which may be of any of the usual well-known forms of construction.

B are the handles, which for lightness and strength may bemade of angle-iron, and braced in any of the usual ways.

G is an iron or steel beam, of an inverted-U form. This beam may he of rolled iron or steel, and made in bars of any length, and cut into proper lengths for a plow-beam or it may be struck up into its proper form with suitable dies and pressure out of plate metal, or turned over a formeroperations that are familiar to mechanicians.

The ends of the beam (1, when out to the proper length, may be heated and welded into a solid instead of a hollow form to admit of its rear being united to the handle, and making suitable provision at'its point for the ring I) or elevis, to which the team is hitched.

c is the standard of the plow; it passes up into the hollow of the beam, and the two are secured together by a screw-bolt or rivet, d, as shown in Fig. 2. The thickness ot'thestaudard may be such as to snugly tit the hollow of the beam, and when the beam and standard are bolted together they mutually strengthen and support each other by a very simple junction. In casting, a hole may be left in the top of the standard, and the flanges ot the beam are punched through to form the bolt-hole.

e is a brace for bracing the standard and beam. The forward end of this brace passes up into the hollow of the beam, and is secured thereto by a screw-bolt or otherwise, and is entirely protected by the flanges of the beam, so that nothing will catch or hang to it.

The shape of the beam when finished and ready to he joined to the other parts of the plow can'be seen at Fig. 3. It is in its best form for strength, and particularly in its best form for being secured to the other necessary parts of the plow. A beam of this kind,- that weighs some twelve pounds, will be strong enough to resist all the strain to which a plow is ordinarily subjected, the first cost of which wouldnot exceed fifty cents.

Of course heavier plows would require heavier beams at a greater cost.

Having thus fully described the nature and object of my invention, I would state that I do not claim a tubular plow-beam; but

What I do claim as new, and desire to secure by Letters Patent, is-

An iron or steel plow-beam of an inverted-U form throughout its main length, and welded or compressed at its ends, and so made as to be capable of receiving the top of the stand ard into its hollow portion, and be otherwise conveniently connected to or with the other portions of the plow, and so as to make a cheap and efficient junction of the several parts thereof, and produce a cheap, strong, and durable plow-beam, as herein set forth.
