ICE-PICK.

SPECIFICATION forming part of Letters Patent No. 441,333, dated November 25, 1890;

Application filed September 19, 1890. Serial No. 365,475. (No model.)

To CLZZ whom it may concern:

Be it known that I, ALBERT B. SCHOFIELD, of Brooklyn, in the oounty of Kings and State of New York, have invented a new and useful Improvement in Ice-Picks, of which the following is a specification.

My invention relates to an improvement in ice-picks in which a sliding weight, which acts as a hammer, is arranged to strike an abutment upon the shank of the pick to embed the cutting edge or point into the ice.

The object is to provide a device of this character in which the shank shall be light and stiff, and in which the parts may be assembled in a simple and effective manner, so as to split the pieces of ice of various dimensions and thicknesses in the direction desired.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a view of the pick in side elevation. Fig. 2 is a transverse section through line oc 00 of Fig. 1. Fig. 3 is a partial view, in side elevation, showing the shank provided with points instead of blades. Fig. 4 is a partial view showing the shank provided with a single blade, instead of two separate blades. Fig. 5 represents the weight or hammer provided with perforations, instead of grooves, for the reception of the parts of the shank; and Fig. 6 represents the abutment formed in two half-sections and secured upon the shank.

A A represent the two parts, rods, or bars of the shank. It is preferably formed of a single piece of wire bent in U- shaped form, as shown, the parts A and A extending parallel with each other and spaced apart. The bight Cb at the upper end of the shank forms a convenient means for suspending the pick upon a hook or nail when not in use. In the form shown in Fig. 1 the free ends of the parts A and A are flattened into cuttingblades a, the blades being preferably arranged in alignment edgewise. Above the blades a the parts A and A are united by an abutment B, which forms at the same time a seat for the impact of the hammer or weight, and also a binder for holding the two parts A A in position relatively to each other. The abntment B may be formed in one piece, as shown in Fig. 1, and provided with perforations b therethrough for the reception of the parts A A, or it may be formed in two half-sections B, as represented in Fig. 6, the

two half-sections being provided with rccesses b, which,when the sections are united, serve to surround snugly the parts A A. The abutment B is held securely against dis placement toward the cutting blades a either by the spreading of the parts of the shank in proximity to its lower edge, as shown at a or it might be riveted to the shank or otherwise secured in any well-known or approved manner.

The weight C is provided at its opposite sides with grooves o, adapted to receive the adjacent sides of the parts A A of the shank, and when adjusted is securely held in a free vertically-sliding movement between said parts of the shank. Instead, however, of being provided with grooves, as shown in Figs. 1 and 2, the said weight may be provided with perforations, as represented in dotted lines at o, Fig. 5.

In the place of the blades a the free ends of the parts A A may be pointed, as shown at af, Fig. 3, or a single blade a may be secured to the free ends of the shank, as represented in Fig. 4.

The parts may be assembled by first forming the shank and then, before the cutting points or blades are formed, the weight C may be slid into its position and the abutment B driven over the free ends of the shank into its position. The free ends of the shank may then be spread or pointed, or a blade, as a may be fixed thereto. Of course where the abutment is formed in two half-sections, as shown at B, it may be placed in position after the points or blades have been provided.

By the above construction I secure ashank which is stiff and at the same time light, while its formation is such as to readily in dicate to the touch the direction in which it should be placed in order to split ice as de sired. It may also be held firmly and truly in the hand without 1iability of turning, while the points or blades at'the free ends of the parts beingseparated from each other insure a separation of the ice in the line of direction in which they engage it. The formation of the shank in two parts further ICO admits of securing the weight in sliding adjustment, as shown in Fig. 1, simply by grooves along its sides, instead of the more expensive structure shown'in Fig. 5.

W'hat I claim as my invention is 1. An ice-pick the shank of which consists of a pair of bars 01 r0ds having their free ends sharpened, an abntment seeured to the said rods or bars, and a weight free to slide up and down between the said r0ds or bars, substantially as set f0rth.

2. An ice-pick the shank of which consists of a rod 01' bar bent into U-shaped form and having its free ends fiattened into cutters, an abntment secured to the branches of the shank, and a weight having grooves in ALBERT 13. SOHOFIELD.
