IMPROVEMENT IN PR'UNING IMPLEMENTS.

Specification forming part` of Letters Patent No. 131,703, dated September 24, 1872.

To all whom it may concern:

'Be it known that I, JAMES REYNOLDs,of the city of Washington and District of Columbia,have invented an Improved Pruning `l Vand Trimming Implement; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those rivets, so that it may be removed or replaced when needful, the cutter H, shaped like .a birds bill, and having its sharp cutting-edge onthe under side. This serves of itself, without' any other cutter, for a great variety of trimming, by a mere pulling of the implement,

so that the blade may sever the twig or branch, the pulling movement being the easiest one `for the operator, and the most eicient as compared with a pushing or a lateral movement, in either of which more power is required and more lost. In conjunction with such blade I also employ a downwardly-inclined sharp blade, B, on a stock, which is fitted by means of a slot, 2, therein, and a pin or screw, 3,011 the frame, to reciprocate in a straight line lengthwise of the implement, the same being pulled down or away from the blade by means of a rod, O, and connecting-rod D, against the force of a powerful sprin g, 4, coiled within, and secured at its top to the cylinder or sheath E, through which rod G passes. An eye, 5, on the handle F, serves to guide the rod or wire D, and a hook at the lower end of the latter serves to lock the two blades out of connection and joint action whenever they are not wanted to do the duty of shears. When acting as shears, however, the hook'is set free, and thus permits th'e blade B, after being pulled down and suddenly released, to fly with force toward the stationary blade and out off any intervening twig `or branch. The two cutting-edges occupy such positions relatively to each other that in the motion of B in cutting its edge traverses the edge of the cutter H and gives a sawing or shearing action upon the wood, and the greater curvature near the tip of the cutter H also prevents the wood from escaping from between the blades withoutlbeing severed. The cutter B is also removable at will, being .attached by screws. The saw Gr is riveted to the lower arm 6of the frame, and

at its other end to a plug, 7, which passes l through a socket, 8, on an outward bend, 9, of the bow-frame A, ascrew-thread on the plug or bolt 7, and a thumb-nut,10, serving to tighten the saw, as required.

I claim- The combination ofthe stationary bill-shape blade with the blade B, arranged to slide in right lines, and operated, when in the act of cutting, by the force of spring 4, as shown and described.
