Letters Patent No. 96,740, dated" 'November 9, 1869.

IMPROVEMENT IN WEEDING-IMPLEMENT.

The Schedule referred to in these Letters-Patent and making' part of the same To all whom 'it may conce/rn Be it.known that I, SPENCER SPRINGSTEAD, of

lVestchester, in the countyfoi' Westchester, and State supposed to be looking in the direction of the arrow,

oSimilar letters indicate corresponding parts.

This-invention relates to that class of "weeding-implements which is pushed or thrust forward by the operator, instead of being drawn backward, as is the 'case in using the ordinary hoe.

'1t 'consists in a blade of a general conicall or taperingrform, each side having' lateral, dart-shaped' teeth, gradually diminishing in Flength toward the point of the blade, andwhose axes `are inclined in a forward direction atan angle of about forty-five degrees with the axis of the blade, the tpoint of the blade consisting cfa broad tooth, whose forward edges form in front vnearly a right angle with each other, when they recede, on each side, in. lines about parallel with the rear edges of the lateral teeth. Each tooth is bevelled, and sharpened, to make sharp cutting-edges.

The letter A designates the weeder.

Itis secured to a handle, B, in any proper manner, at an angle of forty-five degrees, morel or.less.

The point C ofthe blade, or rather its front tooth, has double edges, D D, each inclined backward at an angle of about forty-five degrees, more or less, with the axis of the blade.

From theline of its greatest diameter, the sides of the front tooth recede, as at E E,` toward the front edges of the first lateral teeth on each side of the blade.

- From this part of the blade, the lateral teeth com'- mence and occupy the whole space from thence back to the rear of the blade, each tooth increasing in length and breadth as the series progresses toward the' rear, and increasing also. in their distances from the axis ofthe main blade; and, furthermore, the several lateral teeth, owing to the general tapering form of the main blade, have their forward edges of less length than their rear edges.

The lateral teeth are designated by the letter F. Their front and rear edges are sharpened so that lthe weeder can be operated with good effect, both when it is propelled vstraight forward, and when it is pushed in directions parallel with the axes of the lateral teeth,

or sidewise.

-The main blade has its greatest thickness between the lines G G, whose forward parts converge toward the front, and from those lines the top surface of the blade is reduced in thickness toward each side, each lateral tooth, as well as the front tooth, having a double bevel on, its surface, beginning at its axis, and proceeding toward its edges, but the bottom or under surface of the blade is left fiat or in the same uniform plane, as shown in fig. 2.

My Weeder is operated by propelling or pushingy it Its naro'w front or point enables the gardener to start theimplement with caseand its gradually-expanding sides, provided with teeth which increase in length successively, enable him to cover a great breadth in the thrust or out made by the implement.

The weeder may be stamped out of sheet-steel, and ground down to form the various bevels of the blade and teeth.

What I claim as new, and Adesire to secure by Letters Patent, is-

l. My improved propelling Weeder, having a tapering blade A; with lateral teeth on each edge F, made and arranged substantially as described.

2. The front tooth C, in combination with the lateral teeth F, substantially as described.

This specification signed by me, this 4th day of September, 1869.

S. SPRINGSTEAD.
