ADOLPH H. GABEREL, OF FREDERIOKSBURG, OHIO.

CU LTlVATOR-POINT.

SPECIFICATION forming part of Letters Patent No. 458,338, dated August .25., 1891.

Application filed February l0, 1891. Serial No. 380,923. (No model.)

To all whom it may concern:

Be it known that I, ADOLPH H. GABEEEL, a citizen of the United States, residing at Frederioksburg, in the county of Wayne and State of Ohio, have invented a new and useful Cultivator Point, of which the following is a specification.

My invention relates to improvements in cultivators; and the objects in view are to provide a cultivator especially adapted for cultivating corn, in which the points of the shovels thereof are removable and adjustable, and, furthermore, to provide an easily-operated and simple means of fastening and adjustability.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed outin the claim.

Referring to the drawings, Figure l is a perspective of the lower portion of one of the standards of the cultivator, the shovel, and the adjustable point, all constructed in accordance with my invention. Fig. 2 is a rear perspective of the same. Fig. 3 is a transverse section. Fig. 4 is a vertical longitudinal section. Fig. 5 is a detail of the point.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I employ the usual number of cultivator-standards and shovels and to each shovel applya point, and as the standards and shovels are alikea description of one is all that is necessary to secure a full understanding of my invention.

l designates a standard, the lower end of which is bifurcated to form an intermediate opening 2, the opposite edges of which are undercut to form guides 3. Each of the bifurcations is provided upon its rear side opposite its guide with a pair of perforated bearing-ears 4f, which occur at each side of a slot 5. Pins 6 arepassed through the perforated ears, and upon the same are mounted eccentric-levers or binding-cams 7, the binding-faces of which extend through the slots into the guides. To the front faces of the bifurcations is riveted an ordinary shovel S, in this instance of semicircular shape and fiat, or the same may have any other shape de sired.

9 designates the point, which is of a size to fit within and between the guides 3 immediatelyin rear of the shovel, and has its lower end slightly disposed to the front and reduced, as at l0. It will be observed that the cam-faces of the levers 7 serve to bind against the rear side of the point, thus clamping the same securely between themselves and the rear face of the shovel. By raising the lever 7 the point may be adjusted so as to extenda greater or less distance below the shovel, or said point may be entirely removed for the purpose of sharpening, repairing, &c.

From the above description it will be apparent that I have succeeded in providing a point that can be readily removed for repairing and other purposes, that is capable of adjustment, and all without the necessity of employing tools for such purpose, the adjustmentbeing readily accomplished in the iield.

In operation the shovels follow along successively in a row and serve to hill the corn in the usual manner.

Having described my invention, what I claim is- The combination, with the depending bifurcated standard having undercut opposite edges, each bifurcation being provided with a slot and ateach side of the same with a perforated lug, bearing-pins mounted in the lugs, eccentric or cam levers mounted on the pins, a shovel secured to the faces of the bifurcations, and a point inserted within and removable from between the undercut edges, and clamps between the cam-levers and the shovel, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in presence of two witnesses.

ADOLPH H. GABEREL. Witnesses:

W. R. SHIELDS, A. C. SMITH.
