Specification forming part of Letters lPatent No. 136,820, dated March 18, 1873.

To all whom it may concern:

Be it known that I, MYRoN DE GRoonT,` of

n the town` of Eaton, in the county of Madison and State ot' New York, have invented a cer'-` not be slivered, and will consequently beY lett in a better condition to heal over. My imjprovement consists in so constructing 2pruniing-shears of the character described that the operator may cut off limbs in the manner stated, upon opposite sides of a tree, without shifting his position, on simply reversingl the instrument, without changing his handson the handles, and that in, using the shears the hand operating the blade must always be moved toward the handholding the handle of4 the supporting-hook, in which way the greatest power can beV exerted." VTo `this end 'the double hook is made of anchor-like form overhanging the blade, and beyond the pivot the A respective shanks or tangs are'bent away from each other suiciently to"allow the handles to pass each other.

Figure 1 is a front elevation of my improved pruning-shears. Fig. 2 is an edge view there of'.

The same .letters of reference are employed in both figures in the designation of identical parts.

A refers to the two-edged blade and B to the double or anchor-like hook, the respective tangs A and B of which are pivoted together ata by a strong rivet. The blade beginsclose to the fulcrum or pivot, butthejiukes b and bf of the hook are some distance above the same, so that when the shears are opened and the hook lll is held in a vertical position the fluke, at the time acting with the blade, will hang directly over the cutting-edge thereof. yThe tangs are bent in the manner clearly shown in Fig. 2, throwing the handles C and D apart so that they may pass by each other in turning the blade from one side to the other of the double hook.

l In using the shears the handle C connected to the blade is grasped with the right hand, and hook-handle D with the left. In apply ing the instrument to cut o a limb one of the lukes is hooked over it, holding the hook-handle in about a vertical position and so that itV shall be nearest to the trunk of the tree, while the handle C is elevated' to vopen the shears the required distance. On moving the handle C toward the handle D the blade will cut through the limb from the under side, and in an-upward direction, with the hook bearing against the stump. To cut oi a-lilnb upon the opposite side of the tree in the 'same way it is only necessary to reverse the shears by moving the handles past each other without changl ing the hands. rI he other edge of the blade will then act in conjunction with the other fluke of the hook in precisely the same manner. Y

Thus the operator may stand in one position and prune a tree, as stated, nearly all around.

What I cla-im as my invention, and desire to secure by Letters Patent, is

Pruning-shears composed of a two-edged blade, A, and an overhanging double or anchoir-like hook, B b b, the respective tangs A' and B of which are bent, throwing the handles out of line so that they can move past each other, all substantially as and for the purpose specified.

In testimony whereof I have signed my name 'to the foregoing specification in the presence of two subscribing witnesses.

MYRON DE GROODT.
