UNITED STATES PATENT ()FrIcEo GEORGE G. AIKEN, OF NASHUA, NEW HAMPSHIRE.
IMPROVEMENT IN CULTlVATOR-T EETH.
Specification forming part of Letters Patent No. 27,092, ated February [4, 1860.
To all whom it may concern:
Be it known that I, GEORGE G. AIKEN, of Nashua, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Cultivator and Harrow Teeth; and ldo hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the accompanying drawings, forminga part of this specification, in which- Figure l is a perspective side view of the tooth removed from the grooved plate by means of which it is attached to the frame of a cultivator or barrow. Fig. 2 is.an elevation view of the hind end of the tooth, and Fig. 3 is a top view of the grooved plate by means of which the tooth is attached to the frame of the cultivator or harrow.
Like parts are indicated by the same letters in all the figures.
To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.
The tooth, consisting of the tenon a, vertiea-l colter A, mold-boards or flanges O O, and smaller plows or cutters D D, is all made of iron and cast in a single piece. The front of the tooth is brought to an edge and shapedin the form of a sled-runner, as represented in Fig. 1, so as to pass more readilyoverobstructions. The distance between the tenon a and the bottom of the flanges O G is about the length of the cultivator and barrow teeth in common use, and the distance from the point of the colter A to the corners of the flanges O is about twice the height of the tooth.
B, a top view of whichis represented in Fig. 3, is a plate of east-iron, the bottom side of which is furnished with a wedge-shaped dovetail mortise to receive the tenon a, as shown in-Fig. 2, said plate being confined to the under side of the cultivator or barrow frame by means of bolts passing through the holes I). I propose attaching permanently to the frame as many of these plates B as it is ever desirable to use teeth at any one time, and, if it is required to use a less number, it is obvious from the shape of the mortise and tenon that the surperfluous teeth may be readily removed,
a simple blow of a hammer or stone on the back of the tooth being all that is necessary to loosen it. It is also evident that this method of continin g the teeth is self'fastening, theaction of the soil upon them while in operation tending only to drive the tenon a still faster into the wedge-shaped mortise in the under side of the fixed plate B. The convenience of this method also, when it is desirable to vary the number of teeth to he used, or repair a broken tooth or insert a new one, is obvious, inasmuch as the use of bolts and screws will be entirely dispensed with and the operation performed with great dispatch.
The general sh ape ofthe mold-board or flange (3 will be seen by inspecting Figs. 1 and 2. Commencing (see Fig. 1) at the bottom of the colter, at 1, it runs upward to the point 2, near the center of the back of the tooth, and horizoutally to the point 3, the outer edge being sharp, as represented in Fig. 2. The action of these mold-boards is to stir and lighten the soil by raising it up and causing itto fallback over the hind end of the tooth.
D D are the smaller plows or cutters, the shape and relative position of which are shown in Figs. 1 and 2, their object being to splitthe furrow raised by the mold-boards G G, and thereby increase the pulverization, while the under sides of D D operate as the mold-board of a plow, turning the soil toright and left, making room for the superincumbent earth to drop down into the furrows or trenches formed thereby, which not only mellows the soil, but also operates most favorably for mixing and distributing manure and seed.
The tooth is very simple, cheap, strong, and durable, and performs the work required in a better manner than any other tooth with which I am acquainted.
What I claim as my inventiomand desire to secure by Letters Patent, is
The combination and arrangement of the fixed plate B, vertical colter A, flanges or mold boards 0 O, and cutters D D, substantially as set forth.
GEO. G. AIKEN. Witnesses:
ELIAS FORBES, MARY FORBES.
