J. WILLIAMS. GULTIVATOR TOOTH.
Patented Dec. 23, 1884.
E U m mm 4 Zmw JITNESEEIE JOSEPH WILLIAMS, OF SAN J OSE, CALIFORNIA.
CU LTIVATO R-TOOTH.
SPECIFICATION forming part of Letters Patent No. 309,671, dated December 23, 1884:.
A pplication filed July 16, 1884.
To all whom, it may concern.-
Be it known that'I, Josnrrr WrLLIAMs, a citizen of San Jose, in the county of Santa Clara and State of California, have invented a certain new and useful Oultivator'Tooth, of which the following is a specification.
This invention relates to an improved tooth or prong for cultivators, or such agricultural implements as have a triangular frame set with teeth, prongs, or shares, and drawn by a horse who walks in the balk or sag between the rows or ridges'of corn, potatoes, or other plants, the animal being hitched to the apex of the frame, and the implement being guided by a pair of handles at the rear thereof.
In the accompanying drawings, forming a part of this specification. Figure 1 is a side elevation of my improved cultivator-tooth. Fig. 2 is a cross-section on line X X of Fig. 1. Fig. 3 is a perspective view of the point. Fig. 4t is a front elevation of the share or mold board.
Similar letters of reference are used to designate like parts throughout the several figures. v
A represents the standard or prong of the cultivator-tooth, extending down from the frame-work oi" the harrow, and to which is attached the forwardly-projecting point or prong B. This point is made triangular in cross-section, and tapers from the heel or point of attachment to the standard A down to the forward end or point thereof, and is attached to the said standard by means of a screw or threaded bolt, 0, so that when the under side of the point becomes worn by contact with the earth the said point may be partially rotated, and a new face or surface will be presented upon the lower side thereof.
To the standard A, just above the connection made with the point, I attach, by means of the screw or bolt D, the double share or mold-board E, having upon either side arounded concave face or surface adapted to throw the land or cut portion of the earth upon both sides of the advancing cultivatortooth, This share or mold-board is cut from (No model.)
a sheet of metal, and in the form shown in front elevation in Fig. 4, andis made reversible, so that when the lower points become worn away the share may be reversed, and the end or points of the said mold-board or share which had previously been uppermost may be placed downward, so that they will be first to engage the swath or slice of earth cut and raised up by the cultivator-tooth. In cutting out this share I take a piece of plate metal having a rectangular form and round off the two sides in a partially circular manner, and then cut in from each end a V-shaped notch tapering inward toward the center of the plate, and leaving two points, a a, at each end, and when the share is placed in position upon the standard the uppermost of these points will embrace the standard, while the lowermost points will embrace or lap over the heel of the cultivator-point, one upon each side, as shown in Fig. 1. It should here be remarked that when the said cnltivator-point is tightened up against the standard and made ready for use one of the flat sides of the 'point is laid next the surface of the ground,
while the triangular edge is placed uppermost, and it is this triangular upper edge that enters the V-shaped notch cut in the double share or mold-board. This tooth can be applied to any form of cultivator-frame, and the attachment of the upper end of the standard or shank to the framing is made in the usual manner.
Having thus described my invention, What I claim, and desire to secure by Letters Patent, is
The combination of the standard A, adj ustable triangular point B. and the reversible notched share or mold-board E, substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
JOSEPH \VILLIAMS.
