Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed April 21, 1906- Serial No. 313,077-

To all whom, it may concern:

Be it known that I, ALEXANDER MORAE, a citizen of the United States, and a resident of Pendleton, in the county of Umatilla and State of Oregon, have invented certain new and useful Improvements in VVeeders, of which the following is a specification.

My invention is an improvement in weeders and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof Figure l is a side elevation of my improved weeder. Fig. 2 is a front view thereof, and Fig. 3 is a plan view.

In the present embodiment of myinvention the weeding mechanism is mounted upon a frame A, comprising transverse angleplatesc a connected at their ends by end bars a a, and at the center of the angle-plates are mounted a pair of spaced cross-bars a a, the rear end of said cross-bars being extended beyond the transverse bars.

A shaft B, having cranked ends I), provided with journal-pins b, is .j ournaled transversely of the frame at the forward end thereof, and wheels I) are mounted upon the journal-pins. A lever b is secured to the center of the shaft at one side of one of the central cross-bars, and the said lever is provided with a tooth b engaging a quadrant b secured to the frame, whereby to maintain the lever in its adjusted position, the tooth being connected by a link I) with the gript", pivoted to the lever, and the tooth being pressed downward by the spring I). A second shaft O is journaled transversely of the extended ends of the central cross-bars, the said shaft being provided with spaced crank-arms c, in which is journaled a wheel 0 An upwardly-extending arm 0 secured to the shaft O, is connected by a link 0 with the lever 6 whereby to manipulate the shafts B and C in unison for the purpose of adjusting the frame with respect to the wheels.

A plurality of spaced series of brackets a and a are secured to the frame and depend therebelow, the said brackets having their free ends curved rearwardly, as at a. Rearwardly-arched arms d are pivotally connected to the brackets, and the free ends of the arched arms of each series are connected by a blade D. Shafts E E are journaled upon the frame at the rear of each series of brackets, and the said shafts are provided with downwardly-projecting arms 6, the said arms being connected to the rearwardly-arched arms by pairs of links e e pivotally connect-- ed upon each side of said lever-arm and said arched arm. A plate a having a widened end 6*, is secured to the upper face of the shaft-arm e for the purpose of limiting the downward movement of the said arm 2. A lever e is secured to the front shaft and is provided with a tooth for engaging a toothed quadrant e, the said tooth being connected by a link a with a grip e, pivoted to the lever and normally maintained in its engaged position by a spring a. A second lever e is loosely mounted upon the shaft E, the said lever also being provided with a tooth e engaging a quadrant e whereby to maintain the lever in its adjusted position, the said tooth being connected by a link 6 with a grip e pivoted to the lever and normally maintained in its engaged position by a spring a". The shaft E is provided with an upwardly and forwardly projecting arm 6 connected by a link (2 to the lever e, whereby the said lever may manipulate the rear shaft to raise and lower the rear blade.

On the upper face of the frame, at the center thereof, is secured a spring-plate g, to which is attached a seat G, and to the front of the frame at the ends thereof are attached doubletrees H by means of clevises h, engaging with draw-plates h of any suitable form.

In operation the blades are set in. such po sition that they out just beneath the ground, and should one of said blades become choked or clogged said blade may be lifted from the ground by means of the lever attached thereto, while the other blade remains in place. It will be evident that the blades may be used alternately, thus effectually preventing clogging of the Weeder. By securing the blades to the rearwardly-arched arms,pivoted to the rearwardly-bent end of the bracket, the said blades during the elevation thereof are moved rearwardly at a slight angle with respect to the ground and after freeing from the ground move quickly upward in the most favorable position for quickly freeingthem from the accumulated weeds, &c. When in their upward position, the arch of the arched arms is almost directly upward, thus allowing all accumulations to fall easily therefrom.

I claim 1. A weeder, comprising a frame, a shaft, having cranked ends journaled transversely of the frame at the front thereof, wheels on the ends of the shaft, a lever secured to the shaft and projecting upwardly therefrom,

means for retaining the shaft in its adjusted position, spaced cross-bars at the center of the frame and projecting rearwardly therefrom, a shaft having spaced crank-arms journaled on said projecting ends, a wheel journaled in the crank-arms, an upwardlyprojecting arm secured to the shaft, a link connecting said arm with the lever, a plurality of spaced series of brackets having rearwardly- 'bent ends depending from the frame, rearwardly-arched arms pivoted by one end to the ends of the brackets, a blade connecting the arms on each series of brackets, and means for manipulating the arms to raise and lower the blades, comprising shafts journaled on the frame at the rear of each series of brackets, a plurality of downwardly-projecting arms secured to each of the shafts, links connecting the arms to the arched arm adjacent thereto, a plurality of levers on the forward shaft, one of said levers being fixed thereto and the other journaled thereupon, means for retaining the levers in their adj usted position, an arm fixed to the rear shaft, and a link con necting said arm with said lastnamed lever.

2. A weeder comprising a frame, wheels for supporting said frame, means for adjusting the frame with respect to the wheels, a plurality of spaced series of brackets having rearwardly-bent free ends depending from the frame, rearwardly-arched arms pivoted to the brackets, blades connecting the free ends of the arched arms of each series, shafts having depending arms secured thereto journ aled on the frame at the rear of each series of brackets, links connecting the depending 'arms with the rearwardly arched arms,

means for independently rotating said shafts whereby to adjust the blades, and means for retaining the blades in their adjusted posi tion.

3. A weeder comprising a frame, wheels for supporting the frame, means for adjusting the frame with respect to the wheels, a plurality of spaced series of brackets having rearwardly-bent free ends depending from the frame, rearwardly-arched arms pivoted to the free ends of the brackets, blades connecting the free ends of the arched arms of each series, means for independently adjusting the blades, and means for retaining said blades in their adjusted position.

4. A weeder comprising a frame, means for supporting the frame, means for adjusting the frame with respect to the supporting means, a plurality of spaced series of brackets depending from the frame, rearwardlyarched arms pivoted to the brackets, a blade connecting the free ends of the arms of each series, and means for independently adjusting the blades.

5. A weeder comprising a frame, means for supporting the frame, means for adjusting the frame with respect to the supporting means, a plurality of spaced transverse series of brackets depending from the frame, blades arranged transversely of the frame and supported by the brackets, and means for independently swinging said blades on said brackets.

6. A weeder comprising a frame, means for supporting the frame, means for adjusting 'the frame with respect to the cutting means,

a plurality of cutting-blades supported below the frame and extending the full width thereof, and means for independently adjusting the blades into and out of cutting position. 7. A weeder comprising a frame, means for supporting the frame, a plurality of cuttingblades, supported below the frame, and extending the full width thereof, and means for independently swinging said blades into and out of cutting position.
