UNI ED STATES PATENT OFFICE.
JOHN S. HALL, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN PLOWS.
Specification forming part of Letters Patent No. 144,760, dated November 18, 1873; application filed June 20, 1873.
To all whom it may concern:
Be it known that I, JOHN S. HALL, of Pitts burg, in the county of Allegheny and State of Pennsylvania, have invented a new Improved Plow; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a side elevation, and Fig. 2 a rear elevation, of my improved plow.
The invention relates to that class of plows having reversible mold-boards, and will first be fully described, and then pointed out in the claim.
In the drawing, A represents the beam of a plow, provided with a handle projection or plate, a, quite or nearly at right angles to the rear thereof. It serves the several purposes of suspending the hook B that holds the moldboard (Jon either side of beam, of forming a secure support for the handles D 1), and also serves conveniently to hold a wrench, E. In order to serve these purposes, it is perforated at a for the hook, at a a for the bolts that hold the handles, and vertically at a to hold the wrenches. The hook possesses great utility in bracing the mold-board and beam against any strain which tends to destroy their relative position, and this end is attained by its connection with the rear end of mold-board and the rear end of extension to. This beam has also two branches, A A that form the land-side, the former having a vertically-perforated foot, a, which is held to thesole F by a screw, G, whose head is secured in the sole, while the shank extends up through the foot and receives a nut, G. The other branch,A has its end forwardly obliqued and passed into a socket. I is a slotted wedge, which passes between the foot a and the sole, being movable on the clamp-screw to regulate the pitch or depth of the plow. Of course, as the wedge is driven to a greater or less extent, the front end of beam is depressed, and the horses thereby compelled to lift the point of plow higher and higher. The mold-board O has an angular subjacent piece, 0, in which enters a rear pivot, 0 journaled in a front end bearing, j. At the other end of sole is another end bean ing, f, into which works the pivot 70 of a connecting-bar, K, which is secured, by branches k k or otherwise, to the mold-board. This bar is secured to the inner side of mold-board. L is a clamp-screw, secured, by a hook, I, to a perforated stud, c projecting from the inside, and near the front end, of mold-board. This screw has a threaded end, which passes through the bar K and receives the clamp-nut L.
By this construction, a slight effort will ena ble the pivots k to be inserted in the end bearings f f, when the screw L and nut L will serve to clamp them in position, yet not with so much pressure as to prevent the pivots from readily turning whenever the mold-board is to be reversed.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The branches A A of beam and the sole F, constructed and combined with the nut-screw and slotted wedge in the manner and for the purpose specified.
JOHN S. HALL.
