GEORGEY WIARD, OE EAsT AVON, NEW YORK, AssIGNoR OE ONE-.HALE His RIGHT To o. w. BOUGE, OE SAME PLACE.
lMPROVEME-NTVIN CASTING PLOW-POINTS.
Specification forming part of Letters Patent No. 165,016, dated J une 29,1875 application tiled May 11, 1875.
provided on the rear side with two converging flanges, forming a socket for securing the lower end of the beam or mold-board in place.
Previous to my invention the molding and casting of these plow-points has been attended with considerable loss of time and material from the following causes: In molding these points the sand composing the wedge-shaped portion of the mold which forms the angular socket in the castin g has to be rammed tightly, in order to render the tip of this portion su fiiciently strong to resist theV pressure of the gases and molten iron. When so packed the sand is apt to adherel to the pattern, in conse quence whereof a portion of the tip is frequently detached from the mold in withdrawy ing the pattern, thus requiring the latter to be replaced, sometimes several times, before the' mold is completed. As these plow-points have to be cast with the flanges downward, the escape of the air and gases from the chamber formed within the mold is so difficult and slow as to frequently prevent the molten iron from filling the mold, causing air-spaces in the casting, which render the same unfit for use. Furthermore, in pouring the molton iron into the mold, the former', in entering under the tip of the wedge-shaped portion, frequently raises or deranges the same, whereby the casting is spoiled.
The object of my invention is to remedy these defects; and it consists in constructing one of the Vflanges on the back of the plowpoint near their point of intersection, with a notch or recess, which enables the mold to be formed with a corresponding bridge or support, which strengthens or braces the tip of` the wedge-shaped portion of the mold, facilitates the molding, and furnishes an escape for the airv and gases during the'process of lcast- 1n g.
In the accompanying drawing, Figurel is a rear elevation of a plow-point provided with my improvement. Fig: 2 is a bottom edge view thereof. Fig. 3 is a section in line a' fc,
Fig. l. Fig. 4 is a rear view of the point with the lower end of the beam inserted in its socket.
Like letters of reference designate like parts in each of the figures. i
A is the curved body of the plow-point, and B B the flan ges arranged `on its rear side, forming a socket for the reception of the lower end C of the beam lin plows having iron beams, and of the moldboard in plows constructed with wooden beams. d is the notch or recess formed in the dange B at or near the point at which it meets the flange B', as clearly shown in the drawing. The notch d is represented in the mold by a corresl'ionding bridge of sand connecting the tip of the wedge-shaped pfor-v tion of the mold with the sand on thc outer side of the ange B. This bridge forms a brace or support for the tip of sand, rmly connecting it with the other parts of the mold, and preventing its being withdrawn with the pattern or deranged by the action ot' the airV and gases or the intlowing molten iron, while i at the same time it forms a communication bctween the different bodies of sand composing the mold, so as to permit a more ready escape of the air and gases confined and generated therein, thereby insuring the production of sound and perfect castings with facility and dispatch.
rlhe en d G of the beam or moldboard is prefl 'erably provided with a projecting extension or lip, c, fitting in the slot d of the flange B, and forming an additional fastening or con nection between the beam or mold-board and plow-point.
What I claim as my invention is- A plow-point provided on its rear sid'e with anges B B and notch d, substantially as and for the purpose hereinbefore set forth.
