MPROVEMENT IN METHODS OF MAKING PLOW MOLD-BOARDS.
Specification forming part of Letters Patent No. 165351, dated July 13, 1875; application filed December 8, 1874.
To all whom it may concera:
Be it known that I, JOSIAH HOLMES, of Pittsburg, in the County of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in MoldBoards for Plows; and I do hereby deelare the following to he a full, clear, and exact description there ot', reference being had to the aeeonpanying drawing forming a part of this specitcation, in which- Figure lis a View of a noldboard blank. Fig. 2 is a section of the same on the line :r a), Fig. l. Fig. 3 is a diagran, showing the manuer of cutting the blank from the bar and the line of rolling the blank. Fig. i is a front elevation of rolls einployed for rolling' the blank, and Fig. 5 is a perspective ot' the same.
Like letters refer to like parts wherever they oecur.
My inventiou consists in the nanufacture of nold-board blanks by the following steps First, cutting the bar into diamond or similar shaped sections, and then passing the sections between beveled rols, which leave the proper tlickness of the metal at the point, whereby nold-boards ot' the same size may be thickened for different distanees front the point, and nold-boards ot' different sizes and thicknesses may be produced from the same bar or skelp by the same method and rolls.
I will now proceed to describe the invention so that others skilled in the art may apply the same.
lu the drawing, A represents the blank, having an inereased thickness from the point a to the dotted line i, including the entire point ot' the blank fron the highest point of the curved edge to the base. Ehe portion a' ot' the blank, in rear of the dotted line i, is ot' uniforn thickness, or may be tapered toward the rear edge ot' the blank it' it is desired to reduce the weight of metal at those points where not actually needed. ln producing the blank above described, I preferably enploy rolls, one of which, generally the lower, is beveled at one end, as illustrated in Figs. 4 and 5, in which B is the upper roll, a id B', the lower, mounted in suitable housiugs G, and provided with the usual adjstingscrew D. he lower roll B is beveled at one end, as shown at b', and is provided with a slidiug or adjustable guide, E, one end ot' said guide being eoncave and resting loosely upon roll B', the opposite end resting upon a cross-bar, F. This guide limits the distance that the blank laps upon the bevel b and enables the different sized blanks to be unifornly rolled, or the same sized blanks to be thickened up Varying distances from the point a.
I proceed as follows: I take a bar, as shown at Fig. 3, twelve feet or more in length, ot' a width proportionate to the width required in the finished blank, say, an average of six inches, which will draw out to ten or twelve at the points where the blank is reduced, as at a', and as thiek as is required at the point a, say, an average of five-eighths ot' an inch. This bar I divide diagonally, so as to obtain diamond or similar slaped forms, as shown at Fig. 3, or a blank having three sides straight, as shown. by dotted line s, which may be done by alternating' straight and diagonal outs. l`he form or blank is then presented to the rolls, the point r, Fig. 3, overlapping the bevel b' of the roll, the points marked bythe arrow k of the form eoineiding with the point on the rolls narked by the arrow k'. By this node of procedure, the metal at the point ot' the blank is left of the desired thickness, while that passing` between the plain portion ot' the rolls is spread to the bre adth required, thus avoidiug the loss ot' serap upon one hand and the lahor of welding' upon the other, and producing a blank fulfilling all the requiremeuts of the trade.
Having thus set t'orth my invention, what I claim and desire to secure by Letters Patent, is
As an improvement in the art of nanufaeturing plow mold-boards, the method herein described.
In testimony whereof I, the said JOSIAI-I HOLMES, have hereunto set my hand.
J OSIAH HOLMES. lNitnesses:
