IMPROVEMENT IN PRUNING-SHEARS.

Specification forming part of Letters Patent No. 147,223, dated February 3, 1874; application filed January 3, 1874.

To all whom it may concern:

Be it known that 1,WILLIAII H. GoLLINGs, of Baytown, in the county of Jackson and State of Missouri, have invented a new and valuable Improvement in Pruning-Clippers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side view of my clippers closed. y Fig. 2 is a side view of my clippers open. Fig. :i is a front view of the same.

This invention has relation to devices for pruning trees, hedges, &c., and it consists in combining with a knife, which receives an endwise movement, on the end of a pole, avibrating clamping-blade, having a serrated edge for holding the twigs against the edge of the cutting blade or knife while severing them from the main branches, as will be hereinafter explained.

rIhe following is a description of my invention: In the annexed drawings, A represents the cutting-blade of the instrument, the cutting-edge of which is slightly curved. The shank a of this knife is secured to a rod, a', which passes freely through the center of a pole, B, and is connected by a pin, i, to a sliding tube, G. A slot, g, limit-s the length of strokes of the tube G. C designates a blade, which has deep notches or serrations c in one of its edges, and which is connected by a pivotpin, p, to two rigid arms, D D, which are xed into sockets d d formed on a ferrule, E. The

pivot p passes through a slot, b b', one portion, b, of which is straight, and the other portion b is curved. Below the pivot p is a guide-pin, c, which is fixed into one side of the blade C near its lower end, which pin c is received into the slot b b', and communicates a vibratory motion to the blade C, when an endwise movement is given to the cutting-blade A. Then the tube G and blade A are moved up to their full height, as shown in Fig. 2, the pin c, by reason. of its being at the lower end of the curved portion of the slot b b', will hold open the blade G. In the act of drawing down thc tube G and blade A, the blade C will be closed on a twig, and will hold it rmly against the cutting-edge of the blade A while this blade severs it. It will thus be seen that the blade v A performs a draw-cut, while the blade C prevents the twigs from slipping.

What I claim as new, and'desire to secure by Letters Patent, is-

The endwise movable cuttingblade A, slotted at b b', and connected to a slide, G, on pole B, in combination with the vibrating blade C, serratedv at c, and connected to fixed arms D D by a pivot, p, which latter and a pin, c, playin the slot b b', substantially as described.

2. Avibrating serratedholding-blade C combi ned with an endwise movable cutting-blade A on a pole, B, as and for the purposes set forth.

1n testimony that I claim the above I have hereunto subscribed my name 1n the presence of two witnesses.
