UNITED STATES- JOHN O. SEGER AND JOHN HOLLINGSWORTH, JR., OF MOORESVILLE, ALA.
`IMPROVEMENT IN PRUN|NG`SHEARS.
Specification forming part of Letters Patent No. 147,868, dated February 24, 1874; application iled August 4, 1873.
To all whom it may concern:
Be it known that we, JOHN C. SEGER and Jol-1N HOLLINGSWORTH, Jr., of Mooresville, in the county ot' Limestone and State of Alabama, have invented a new and useful Improvement in Pruning-Shears, of which the following is a specification:
The invention consists in providing a guard for the blades or cutters, as hereinafter described.
In the accompanying drawing, Figure 1 is a side viewshowing the arrangement of parts. Fig. 2 is an edge view of the same.` Fig. 3 is a cross-section of the cutting-blades taken on the line a: :l: of Fig. l.
Similar letters of reference indicate corresponding parts.
This pruning-shears consists of a main lever, A, having a curved stationary blade, B, and guard O,` and a sharp curved beveled cutting-lever blade, l), and operating-lever E. The fulcrum-pin ofthe two blades is placed on one side of the center at the point F. The fulcrum of the operating-lever E is at the point G, on the main lever A, and is connected with the lever end of the cutting-blade D by the pivoted bar H. A compound-lever purchase is, therefore, obtained on the cuttingblade D, and a drawing cut is given its edge by the location of the fulcrumpin F. The two cutting-edges are curved, the stationary blade p the amount of power required to operate the shears. The guard O is rigidly attached to the stationary blade B. Its face is on the plane ot' the faces ot' both the blades B D, and it guides and supports the thin beveled cutting-blade D, and prevents it from twisting'. I represents projections at the base of both the blades, which allow the fulcrum-pin F to be placed one side of the center, by means of which the drawing out is given.
Having thus described our invention, we claim as new, and desire to secure by Letters Patent- The guard O, in combination with the beveled cutting-blade D, as and for the purposes described.
