To ALL wHoM 1T MAY GONCERN;

Beit known that we, DoN CARLOS Mnrrns'on and TRUMAN PANE WILLIAMsoN, of Stockton, San Joaquin county, State .of California, have invented certain new and useful Improvements in Cultivator-Teeth; and we do hereby declare the` following description and accompanying drawings are suilicient to enable any person skilled in the art or science to which it most nearly appcrtains to make and use our said invention without further invention or experiment. v

v The natureof ourv'invention consists-in providing a cultivator-tooth having a double-pointed bit, so constructed that when the bevel wears from the bottom ofthe point,'it can be turned over, thus sharpening itself, itbeing attached to a standard, over which and the bit is placed a double mould-board or shovel, the whole held together by bolts passing throughthem, and the shareplaced transversely at the bottom. The bitcan also be turned around, and the other end used when the first is worn out.

In order to more fully describe our invention, reference is had to the accompanying drawings, and letters marked thereon, in whichl Figure 1 represents a plan or top-view.

Figure 2, a sectional elevation, taken through the line :z: w, Eg. 1.

Figure 3, a bottom view.

Similar letters indicate like parts in each ofthe figures.

A is a flat bit, made with doublcfpoints, bevelled correspondingly. Over this bit is placed a double mouldboard or shovel, B, allowing the bit to project one. ontwo'incbes, more or less,` from it. Upon the bitirests the foot 'of the standard C,`,curved and bevclled,` so asfto fit between the shovel and bit, the upright end or shank of which has a thread and nut, with which to attach it ,to` the cultivator-frame. An oblong. share or blade, D, is

placed transversely across the bottom'ot the bit, and the edges of the double mould-board rest upon it. This share can also bc changed, so that either edge muy be used alternately, or turned over like the bit so as to sharpen itself. In this position, the wholeA are fastened together by bolts passing through the mould-board, standard, bit, and blade or share. The teeth, =when 4attached to thc cultivator-frame, will hang at an angle, so thatthey 'may enter the ground to the'desired depth, which is regulated by gauge-wheels attached to the frame.

By' this arrangement and construction o f cultivator-teeth, a mechanism is had that will be found admirably adapted for preparing the soil of the Pacific coast for seeding after plowing, it being theusual custom to fallow by cultivator after the land has remained unseeded for a-season', or itmay be used to prepare new ground in its hardeststate,the mould-board not thus being necessary, .and by the use of ourcultivator, the necessity of plowing again is obviated, as the arrangement ot' shares, points, and double mould-board completely dostroysthe weeds, and cultivates the spacesdesigned by the vwidtl'rof the frame.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-v- 1. The double-pointed adjustable'bit A attached to the bcvelled foot of thecurved standard kC, substantially as Aand for the'purpose specified. v I

r 2. The oblong blade or share D, incombination' with the bit AA, substantially asdescribed for the purpose specified. 'i v l The aboveV specification of our` invention signed byus, this 11th day 'of February, 1868, respectively.vv

TRUMAN PANE WILLIAMSON.
