SPECIFICATION frming 'part f Letters Patent No. 646,633, cated Aprn 3,1906.

' Y Application Hed Maj 81, 1899. serial No. 718,881. or@ model.)

ro This invention relates to certain newand useful improvements in holding attachmentsV for shears.

The object of this invention is to provide a simple and effective device or attachment l pruning shears Afor `holding the portion trimmed, and is particularly adapted for use in holding a bunch of grapes orv a rose-stem after the same has been severed by the shears.

My invention also relates -to details of construction hereinafter appearing and particularly pointed out in the claim. v t

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure 1 is a side view of a pair of shears, showing my improvements applied thereto; Fig. 2, a sectional view on the line xm of Fig. 1 looking in the direction of the arrows; Fig. 3, aplan View of what is shown in Fig. l; Fig. 4, a detail perspective View of a portion of a pair of shears, showing another form of my improvements; and Fig. 5, a detail perspective View of the holding-clip, together with the elastic holder.

In greenhouses, particularly Where large quantities of roses and other cut flowers are produced, and in vineyards this invention is specially useful, as it holds the stem containing the roses or other iiowers and the bunch 4o of grapes after being severed, so that it is not necessary to take them with the hand; but they may be gently laid in baskets. Shears which may be applied to any trimming orl tion in Figj2.

4spring-clip M, which extends over the bar O B and C, pivotally connected together, as

shown at D. The bar B preferably carriesl a 5o strip, as shown at E, and has formed therein a filling of Babbitt metal, as shown at F. This is for preventing the edge of the knifeblade :from becoming dull rapidly, as will hereinafter appear. The upper bar is slotted from its forward end, as shown at G in sect t In this slot is inserted a knife H, such knife being held in position by means of rivets or screws I. The lower edge of this knife'is preferably curved to correspond with the interior of the outer endof the bar B, asclearly illustrated at -J in Fig. 4 and as shown-in dotted lines in Fig. l. From Fig. 2 particularly it Will be seen that the bar B projects to each side of the cutting edge of the knife H. Over one of these edges or projections, as shown at K, and adjacent to the knife is mounted an elastic holder L, held in f position lagainst the knife by means of a and'grips the elastic holder L between it and the knife. It will be observed that the lower portionpof the elastic holder is thickened or widened, as shown at N. This widened portion extends outward flush with the outer edge of the bar B and is adapted to conform to the shape of the bar, so that as the shears are brought together this holder will press equally throughout its entire length upon said lower bar. As soon as the knife severs whatever it is cutting it will be pressed down upon the Babbitt filling F, and since such metal is 'quite soft the knife-edge will be prevented from' becoming dulled.

Referring now to the second form of my iuvention, it will be observed that the springclip and elastic holder are formed in one. piece. This, however, is not the preferred form, but in many instances may be substituted for the preferred form. The elastic cushion ct is made of spring-steel or other suitable material and has formed at one end a spring-clip b, which is adapted to extend over the bar C in a manner similar to the clip M. The outer end of this spring-cushion, 95 therefore, is free to yield, and consequently when the branch or twig is severed the sp1-in gcushion a will yield suiiciently to accommodate it, but will at the same time press upon it with sufcient force to hold it between the lower jaw of the shears and said spring.

I do not Wish to limit myself to any particular form of yielding cushion for this purpose, as I Wish to claim, broadly, a holding device for shears for holding cutstems, &c., upon being severed.

It will be observed that the clip M has a slit therein, as shown at O. This is particularly useful for holdingr the rubber cushion firmly in position next to the knife, as it has been found in actual practice that the rubber projects Within such slot or opening, and con- Witnesses:
