HORATIO GAIAE, OF ALBION, MICHIGAN, ASSIGNOR TO THE ALBION IIIANU- FACTIIRING COMPANY, OF SAME PLACE.

SPRING-TOOTH FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 395,562, dated January 1, 1889.

Application filed October 8, 1888. Serial No. 287,617. (No model.)

To aZZ whom it may concern-.-

Be it known that I, IIORATIO GALE, a citizen of the United States, residing at Albion,county of Calhoun, State of Michigan, have invented a certain new and useful Improvement in Spring-Teeth for Cultivators; and I declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the art to which it app ertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specificatioinand in which Figure 1. represents a perspective view of my improved spring tooth for cultivatm-s. Fig. 2 represents parts in detail.

It has been found in the use of spring-teeth in cultivators that when the shoe is fastened to the broad surface of the spring-shank the latter, presenting a broad surface to the front, serves to accumulate grass, weeds, and other debris; and it is the object of my improvement to obviate this dilticulty. This I accomplish by turning a portion of the spring-shank a short distance above the shoe at right angles to itself, thus causing the tooth to present a narrow edge rather than a broad surface to the front.

In the drawings, A represents the springshank ofmy improved spring-tooth, and B the shoe, which may be any desired shape, or a small share, if preferred. The shank A is at a desirable point above the shoe turned at right angles to itself, thus eausin g the portion a to present a narrow edge rather than a broad surface to the front. Attached to the lower end of the spring-shank A is a T-shaped block, 0, to which the shoe B may be bolted, riveted, or otherwise fastened. It will be seen that but one bolt, 0, is necessary to attach this block C to the spring-shank, since it has a firm bearing both on the side and edge of the spring-shank when held in place by the single bolt. I

If desired, the spring-shank may be provided with an elongated opening, or with two or more holes, through which the bolt 0 may pass, thus permitting the shoe to be adjusted to a higher or lower level, as desired.

A prominent feature of my improvement is the provision on the shoe of a web or flange projecting to the rear and perforated for the passage of the fastening-bolt, and in connection therewith the extremity of the springtooth turned so as to present its edges toward the front and rear. Of course any construction whereby this web or flange is provided would be contemplated by my invention, whether it were made integral with the shoe or blade itself or provided by the addition to the shoe or blade of a T-shaped block, as shown, or any other suitably-shaped block.

IVhat I claim is A spring-tooth for eultivators, consisting of a spring-shank turned near its lower end at right angles to itself so as to present its edge to the front, and ashoe havingaweb or flange projecting back at right angles to its face parallel with and adapted to be fastened to the twisted end of said spring-sh an k, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

I-IORATIO GALE.
