No. 466.879. Patented Jan. 12,1892.

PRUNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 466,879, dated January 12, 1892.

Application filed April l6, l8 9].

To aZZ whom it may concern.-

Be it known that I, ROBERT HENRY DIXON, a citizen of the United States, residing at Santa Rosa, Sonoma county, State of California, have invented an Improvement in Pruning- Shears; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of shears inwhich one of the blades hasadouble movement to effect what is known as a draw out.

It consists in the novel connection of the blades and handles hereinafter fully described, and specifically pointed out in the claim.

The objects of my invention are to give to one of the bladesa combined curve and draw movement with betterleverage, to simplify the general construction, strengthen and steady the parts, and give to the movable blade a more secure and stable bearing.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is aview of my shears open. Fig. 2 is a view of the same closed. Fig. 3 is a view of the other side of the shears.

A is one handle, having formed or connected with it the blade B, which may ormay not be in the shape of the usual finger.

O is the other handle, the head of which is halved upon the upper end of handle A, as shown in Fig. 3, and is pivoted thereto by the bolt 0, the nut o of which may be guarded and held, as usual, by the pawland ratchet 0 D is the movable blade. This is pivoted to handle A by a pivot-pin E, passing through one corner of its foot, as shownin Figs. 1 and 2. This pin may be a. simple screw passing throughtheblade-foot and seated in a socket in the handle. The foot of blade D has an elongated slotd,which is fitted at its upper end over the head of the pivot-bolt o, and at its lower end it receives the operating pin or stud F, which passes freely through the slot d and is seated firmly and fixedly in the handle 0. This pin or stud may bea simple screw. The

slot (Z at its upper portion is curved to play Serial No. 389,220. (No model.)

the pin or stud F, while its upper end'exteuds beyond bolt 0. Now when the handles are pressed together, the pin or stud F, moving i11- wardly, travels in slot (Z, and thereby turns the blade D about its pivot-pin E, and at the same time draws it down so that its slot turns upon and also moves down on bolt 0 until the upper end of the slot reaches the bolt 0. This position is shown in Fig. 2, and to reach it the bladeD has hadacombinedcurve and draw motion, which is the most effective one. This construction is further advantageous in that the pin or stud F, beinga simple fixed one, is notliable to work loose, as is the case with a movable pin or bolt,and said pin or stud is simple in construction and readily placed. The whole movable blade D is also more stable and secure, having a great and firm bearing on the handle A, so that it is not liable to twist nor get out of true.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In pruning-shears, the combination of the handle with its finger-blade, the opposing handle, the bolt pivoting said handles to gether, the movable blade having the elongated slot in its foot, fitting and playing over the boltjoining the two handles, the pivotpiu connecting the foot of the blade with the first handle, and the pin or stud fixed in the second handle and passing freely through the slot of the movable blade, substantially as herein described. y

In witness whereof I have hereunto set my hand.

ROBERT HENRY DIXON.
