WEEDING IMPLEMENT.

Specification of Letters Patent.

Application filed July 8, 1913.

Patented May 26, 1914.

Serial No. 777,851.

To all whom it may concern:

Be it known that I, KAYOZI TSUBOI, residing at Portland, in the county of lWIult-nomah and State of Oregon, have invented a new and Improved ll eeding Implement, of which the following is a specification.

My present invention has relation to garden implements and more particularly to means for weeding garden and flower beds and which may also be utilized for transplanting small plants or roots and my said invention primarily has for its purpose to provide a device or implement of the general character stated of a very simple and economical construction in which the parts are compact-1y arranged and adapted for convenient handling and which is effective for its intended purposes.

With other objects in view that will hereinafter appear, my invention consists in the peculiar combination and novel arrangement of parts, all of which will be hereinafter fully explained, specifically pointed out in the appended claims and illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of my weeding implement, the same being shown as in use. Fig. 2 is a longitudinal section there of, the gripping jaws being shown at their closed position. Fig. 3 is a partial longitudinal section of the implement, th gripping jaws being shown at the open position. Fig. 4 is a detail perspective view of one of the jaws. Fig. 5 is a detail perspective view of the slidable stirrup or jaw closing ele-' ment. Fig. 6 is a detail viewof a portion of the lower end of one of the gripping jaws and the root puller attachment therefor.

In carrying out my invention I provide a handle 1 that is fixedly attached to a tang 2 that extends up from one of the gripping jaws or blades, of which there are two opposing members of the duck-bill shape type. The main or relatively fixedly held blade 3 carries the tang 2 and it includes a pair of apertured ears 5 with which are pivotally connected the ends 4: of a yokelike member 10 riveted to or cast integral with the movable jaw 6, which includes a head portion 61 that extends upwardly from the fulcrum of the jaw and is so bent relatively to its lower or gripping end that when the two jaws are at their normal or spread position, as shown in Fig. 1, the said upper end inclines inwardly toward the other jaw, the reason for which will presently appear.

7 designates a cross head that is fixedly connected to or formed integral with the upper end of the jaw 3, one edge 7 0 of which projects beyond the face of the handle and has a pair of apertures 71, for receiving and guiding the side rods 80 of a pull bail 8, the lower end of which carries a stirrup-like member 9, shaped to fit in and to slide upon the fixed jaw 3. Stirrup 9 includes a down wardly and outwardly inclined lip or finger 90 having a concaved bearing face 91 that rides against the inwardly bent upper end of the pivoted jaw 6.

It should be stated that the correlation of the upper end of the jaw 6, the fulcrum for the said aw, the stirrup and the means for slidably moving the said stirrup is such that when the parts are in the normal position (see Figs. 1 and 3) the finger 90 of the stirrup projects below the fulcrum of the movable jaw and by reason of engaging the inwardly bent or gripping part of the said jaw, it causes the said movable jaw to swing outwardly and holds itto the. position shown in the said Figs. 1 and'3.

The-pull bail 8 is automatically forced to its down or normal position by the coil springs 10 disposed about the members 80 and held between the stirrup 9 and the cross head 7 and it has its upper end connected to a link 11 that is pivotally joined to a crank lever 12 fulcrumed on the handle 1 and held in such a manner that in grasping the handle the lever 12 canbe swung inwardly to the position shown in Fig. 2, which pulls the bail 8 against the tension of the springs and causes the finger member on the stirrup 9 to force the pivoted jaw to the closed position.

13 designates a root puller secured to the lower end of the fixed jaw and the same consists of a plate having spur-like bifurcations 14 and the'same is so secured to the jaw that the bifurcations are projected upward and outwardly from the jaw as clearly shown in the drawings.

From the foregoing description taken in connection with the drawing, the complete construction, the manner in which my improved implement may be used and its ad vantages will be readily apparent to those skilled in the art to which it ap'pertains.

What I claim is:

1. In an implement, a relatively fixed penetrating jaw and a movable jaw pivoted to said fixed jaw, means reciprocably mounted on the said fixed jaw and cooperatively engaging said movable aw, the said means including a portion adapted to move to either side of the fulcrum of the said movable aw and to engage the said jaw and thereby open or close the jaws according as the said member is located at one side of the fulcrum or the other.

2. In a garden implement, a handle, a relatively fixed penetrating jaw secured to the handle, a movable jaw pivoted to the said fixed jaw, and means reciprocably mounted on the fixed jaw cooperatively engaging the movable jaw, the said means including a projecting finger that slidably engages the movable jaw and is adapted to be moved to either side of the fulcrum of the said movable aw, the upper and lower ends of the movable aw being inclined inwardly with respect to the fulcrum of the jaw, and means for reciprocably moving the member that engages the movable jaw to thereby rock the said jaw to its open or closed position.

3. in a garden implement, a handle, a relatively fixed penetrating jaw secured to the handle, a movable jaw pivoted to the said fixed jaw, and means reciprocably mounted on the fixed jaw for cooperatively engaging the movable aw, the said means including a projecting finger that slidably engages the movable jaw and is adapted to be moved to either side of the fulcrum of the" said movable jaw, the upper and lower ends of the movable jaw being inclined inwardly with respect to the fulcrum of the jaw, means for reciprocably moving the member that engages the movable jaw to thereby rock the.

said jaw to its open or closed position, said means including a spring controlled thrust for moving the said movable jaw engaging means in one direction and a hand lever controlled means for moving it in the opposite direction.

4. In a garden implement of the character stated, the combination with the penetrating jaw, of a root puller mounted on the inner face of the penetrating end of the said jaw, the said puller consisting of a claw-like member disposed at an outwardly directed angle relatively to the jaw and with its inner end uppermost.

5. A garden implement of the character stated comprising ahandle and a penetrating jaw fixedly connected to the handle, a movable jaw reciprocably mounted upon the fixed jaw, a member slidably mounted for reciprocable movement on the fixed jaw, the said member including a downwardly and outwardly extended plunger finger, a bail connected to the slidable member for pulling the said member in one direction, springs cooperatively mounted on the bail and a fixed jaw for moving the said member in the other direction, and a crank lever mounted on the handle and having a link connection with the bail, the said-movable jaw having its upper and lower portions inclined inwardly toward the fixed jaw.
