~ - 2 -LB/~J(I.
Figure 1 is a schematic s~de view of the tool in accordance with the invention, and Figure 2 is a schematic view, seen from ~ehind, of the tool illustrated in Figure 1.
The planting tool illustrated in Figures 1 and
2 includes a square-section tube 1 having a bevelled bottom portion, a handle 2 mounted integral with a hopper 3 attached to the tube, a fixed jaw 4 attached ~o the bottom portion of the tube, a movable jaw ~ pivot.ably mounted on a shaft 4a on the left-hand portion of the fixe~ jaw in Figure l, a U-shaped foot pedal 6 made integral with t~e movable jaw, and a mechanism 7 acting between the foot p~dal and the tube for retaining the mova~le jaw 5 in an open position, after the opposing jaws 4, 5 have been thrust down into the ground and the movable jaw moved with the aid of the foot pedal into the open position illustrated in the Figures, the mechanism 7 also acting to release the mo~able jaw for .

movement towards the fixed jaw, after the jaws have been pulled out of the ground and removed from the plant, which was taken down between the jaws via the hopper 3 and tube 1 in a previous operation, to arrive in -the planting hole made by the jaws.
The mechanism 7 includes a threaded rod 8, one end of which is in mesh with a threaded sleeve 9 and the other end of which is attached to a shaft 10 extending between, and pivotably mounted in, the two opposing legs of the pedal 6. The end of the sleeve 9 facing away from the rod 8 engages against an abutment, when the movable jaw 5 is moved to its open position illustrated in the Figures. The abutment is formed by the bottom edge of one leg of a short length of angle bar 11, fastened to the rear long side of the tube, the other leg of the bar 11 pxojecting out from the tube being used to fasten one end of a helical tension spring 12. The other end of the spring 12 is fastened to an arm 13 attached to the shaft 10. The spring 12 urges the sleeve 9 anticlockwise about the shaft 10, such that the upper end of the sleeve engages against the abutment with a relatively large force.
A stirrup 19, surrounding the member 11 in the way illustrated in Figure 2, is provided with a shaft 14 situated between the sleeve 9 and the tube 1. The upper end of the stirrup 1~9 is joined onto a rod 15, the upper end of which is taken through a hole in a length of angle bar 16 attached to the tube, and terminates in a bend 17 situated immediately below the handle 2.
The function of the tool will now be summarily described.
With the foot pedal 6 and the movable jaw 5 in their positions illustrated by chain-dotted lines in Figure 1, the tool is pressed into the ground where a plant is to be planted. Next, the right-hand portion of the foot pedal 6 is depressed, whereby it is swung clock-wise around the shaft 4a in Figure 1 so that the movable jaw 5 moves away from the fixed jaw 4 and a hole is made in the ground. During the pivoting movement of the foot pedal, the sleeve 9 is moved downwards while the spring 12 is tensioned and pulls the arm 13-anticlockwose round the shaft 10, the upper end of the sleeve being urged against the member 11. At the end of the clockwise pivot-ing movement of the pedal, the upper end of the sleeve passes the lower edge of the member 11 and into engage-ment against the tuk,e 1. When the pressure on the foot pedal ceases, the upper end of the sleeve will engage against the abutment 11 under the action of the bias in the spring 12, and cannot be removed from this position by mistake.
After a plant has been taken by the planter via the hopper 3, tube 1 and the opened jaws 4, 5 into the hole thus made, the tool is lifted by the handle 2 straight up out of the hole so as nGt to damage the plant. The planter then pulls the bend 17 upwards and the stirrup 19 connected to the rod 15 is pulled upwards. The -- ~ _ stirrup 19 cannot move notably laterally since both its opposing vertical legs are on either side of the member 11. When the shaft 14 meets the underside of the sleev~ 9, the sleeve is pressed out from the abutment on the member 11 against the bias of the spring 12. As soon as the sleeve has left the abutment, the spring 12 pulls the foot pedal 6 anticlockwise round the shaft ga while the sleeve glides towards the member 11. The anti-clockwise movement of the foot pedal is terminated when the jaw 5 engages against the jaw 4.
To adjust the use of the tool to different sized plants, the longest distance between the jaws 4, 5 may be adjusted in a simple way, namely by screwing the sleeve 9 more or less onto the rod 8 after a locking nut 18 has been loosened, thus increasing or decreasing the distance between the upper end of the sleeve 9 and the shaft 10. For a long such distance the jaw 5 is retained by the sleeve in a maximally open position and ~or a short distance in a less open position. The altera-tions of the combined length of sleeve 9 and rod 8 is suitably carried out when the bias of the spring 12 is weakest, i.e. when the jaws 4, 5 engage against each other.
Although only one embodiment of the invention has been described above and illustrated on the drawing, it should be understood that the invention is not limited to this embodiment but is only limited by the disclosures in the claims.

movement towards the fixed jaw, after the jaws have been pulled out of the ground and removed from the plant, which was taken down between the jaws via the hopper 3 and tube 1 in a previous operation, to arrive in -the planting hole made by the jaws.
The mechanism 7 includes a threaded rod 8, one end of which is in mesh with a threaded sleeve 9 and the other end of which is attached to a shaft 10 extending between, and pivotably mounted in, the two opposing legs of the pedal 6. The end of the sleeve 9 facing away from the rod 8 engages against an abutment, when the movable jaw 5 is moved to its open position illustrated in the Figures. The abutment is formed by the bottom edge of one leg of a short length of angle bar 11, fastened to the rear long side of the tube, the other leg of the bar 11 pxojecting out from the tube being used to fasten one end of a helical tension spring 12. The other end of the spring 12 is fastened to an arm 13 attached to the shaft 10. The spring 12 urges the sleeve 9 anticlockwise about the shaft 10, such that the upper end of the sleeve engages against the abutment with a relatively large force.
A stirrup 19, surrounding the member 11 in the way illustrated in Figure 2, is provided with a shaft 14 situated between the sleeve 9 and the tube 1. The upper end of the stirrup 1~9 is joined onto a rod 15, the upper end of which is taken through a hole in a length of angle bar 16 attached to the tube, and terminates in a bend 17 situated immediately below the handle 2.
The function of the tool will now be summarily described.
With the foot pedal 6 and the movable jaw 5 in their positions illustrated by chain-dotted lines in Figure 1, the tool is pressed into the ground where a plant is to be planted. Next, the right-hand portion of the foot pedal 6 is depressed, whereby it is swung clock-wise around the shaft 4a in Figure 1 so that the movable jaw 5 moves away from the fixed jaw 4 and a hole is made in the ground. During the pivoting movement of the foot pedal, the sleeve 9 is moved downwards while the spring 12 is tensioned and pulls the arm 13-anticlockwose round the shaft 10, the upper end of the sleeve being urged against the member 11. At the end of the clockwise pivot-ing movement of the pedal, the upper end of the sleeve passes the lower edge of the member 11 and into engage-ment against the tuk,e 1. When the pressure on the foot pedal ceases, the upper end of the sleeve will engage against the abutment 11 under the action of the bias in the spring 12, and cannot be removed from this position by mistake.
After a plant has been taken by the planter via the hopper 3, tube 1 and the opened jaws 4, 5 into the hole thus made, the tool is lifted by the handle 2 straight up out of the hole so as nGt to damage the plant. The planter then pulls the bend 17 upwards and the stirrup 19 connected to the rod 15 is pulled upwards. The -- ~ _ stirrup 19 cannot move notably laterally since both its opposing vertical legs are on either side of the member 11. When the shaft 14 meets the underside of the sleev~ 9, the sleeve is pressed out from the abutment on the member 11 against the bias of the spring 12. As soon as the sleeve has left the abutment, the spring 12 pulls the foot pedal 6 anticlockwise round the shaft ga while the sleeve glides towards the member 11. The anti-clockwise movement of the foot pedal is terminated when the jaw 5 engages against the jaw 4.
To adjust the use of the tool to different sized plants, the longest distance between the jaws 4, 5 may be adjusted in a simple way, namely by screwing the sleeve 9 more or less onto the rod 8 after a locking nut 18 has been loosened, thus increasing or decreasing the distance between the upper end of the sleeve 9 and the shaft 10. For a long such distance the jaw 5 is retained by the sleeve in a maximally open position and ~or a short distance in a less open position. The altera-tions of the combined length of sleeve 9 and rod 8 is suitably carried out when the bias of the spring 12 is weakest, i.e. when the jaws 4, 5 engage against each other.
Although only one embodiment of the invention has been described above and illustrated on the drawing, it should be understood that the invention is not limited to this embodiment but is only limited by the disclosures in the claims.
