IMPRCVEMENT INPRUNJING-SHEARS.
Specification forming part of Letters Patent No. 13h, S, dated October 1, 1872.
To all whom it muy concern.-
` Beit known that we, SAMUEL J. BEIGE and ELI F. BEARD, of Republic, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Pruning-Shears, of which the following is a specication:4 l
This invention relates to a new and useful pruning trees,
shrubbery, 8vo.; and consists in the construction and arrangement of parts hereinafter de-` scribed. y y
In the accompanying drawing, Figure 1 is y a side view of the shears, showing the cutting blade drawn back ready fora cut, also showing, in dotted lines, the Yposition after the cut has been made; and Fig. 2 is a cross-section `of Fig. 1 taken on the line x x.
Similar letters of reference indicate corresponding parts.
\ A is the stafl' to which the cutting mechanism is attached. Bis the shank of the hook p (l. D is the cutting-blade. The staff A is slotted or grooved, so that the shank B slides therein. E is a wire attached to the end of the shank, which extends downon the outside of the staff', as seen in the drawing. F
3 is a knob on the end of the wire. The cutting is effected by pulling on the knob, thereby. sliding the shank in the stai' and operating the shears. The shank is confined to the groove in the sta by means of the ferrule Gr on the end of the staff, and the clip H which passes through the staff. The cross-section ofthe staff, seen in Fig. 2, shows this clip. The wire E is confined to the out-V side oi the staff by the small staples I I. J is the shank of the cutter-blade, the end of which is attached tothe short end of the bent lever K. This bent lever is pivoted at y the elbowto the arm L of the hook-shank B. y The long end of the bent lever K is connected with the ferrule Gr bythe connection M, the
forked ends of which receive the end of the le'ver and an ear, N, on` the ferrule Gr, thev 4pivot O of which is a fixed point. Thehook l C is the upper termination of a plate or enlargement, P, on the end of the shank B. R
` is a curved slot through this enlargement, and
S is an arm projecting downward in a direction nearly at right angles with the slot. T represents a strap on each side of the arm S, which connects the arm with the upper end of the shank of the'blade D, as seen at U. The pivot which completes the latter connection passes through the curved slot R. As the shank and hook B C are drawn down by pulling on the knob to the position seen in dotted lines, the blade D will also be drawn down, but, at the same time, it will be carried toward the hook by means of the curved slot R and pivot U. The connection T is the radius of a circle, whose center is the pivot V, and the slot B. is an arc of the circle. The blade, it will be seen, has a compound motion, and gives a drawing stroke when applied tol the limb or twigto be out. This drawing cut severs the fiber in the easiest and most effective manner possible. l
The manner of applying the shears will be readily understood from the drawing, the staff being held with one hand while the knob is pulledwith the other. The wire E should be sufliciently stiff when confined by one or more claim as new and desire to secure by Letters Patentl. The shank B having hook c, slot It, an arms L S, in combination with the blade and its operative mechanism, as described, and for the purpose set forth.
2. The radial connection T and pivots U V in combination with the arc or slot It.
3. The arrangement of the bent lever K, blade-shank J, and connection M, substantially as and for the purpose described.
4. The combination of the shank B, with the parts attached thereto, with the staff A, as and for the purposes described.
