ICE-PICK.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed September 13, 1906- Serial NO- 334,432.

To all whom it may concern:

Be it known that we, Paton M. GUIOU, FINLEY I. LUCAS, and EDWIN M. METCALF, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Ice-Picks, of which the following is a specification.

This invention relates to ice picks, and our object is to produce an ice pick by which a piece of ice can be chipped cleanly from a large lump without being broken up into a number of small pieces. 1

A further object is to produce an ice pick which can be operated easily and which is of simple, strong, durable and cheap construction.

To this end the invention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described and claimed and in order that it may be fully understood reference is to be had to the accompanying drawing, in which:-

Figure 1 represents a perspective view of an ice pick embodying our invention. cal section taken on the line II-II of Fig. 1.

In the said drawing 1 indicates an anchor-frame, the same comprising a centrally perforated cross-head 2 and a pair of substantially parallel arms, or guide-rods 3 having their lower ends pointed as at 4.

5 indicates the ice pick, the same being in the form of a'section of'a saw blade with the teeth thereof at the lower edge. e

.6 indicates a stem rigidly secured to the pick at its lower end and extending slidingly through the aperture of the anchor-frame and provided above the latter with a weighted handle 7, the length of the stem being such that when the handle engages the. upper side of the cross-head, the teeth of the pick project beyond the pointed ends of the rods.

8 is a cross-bar secured rigidly upon the handle at its junction with the pick, and said cross-bar is provided with a pair of short longitudinal slots 9 through which the guide rods of the anchor-frame extend, the inner ends of said slots terminating in substantially the same plane as the opposite edges of the pick.

In the practical operation of this pick the pointed ends of the anchor-frame are placed upon the ice in the line of the desired cut to be made therein, and then the handle is grasped and the pick reciprocated 011 the guide-bars so that it shall cut into the ice in the Fig. 2 represents a vertiline mentioned, the guide-bars preventing any turning movement which would permit the pick to cut at an angle to such. line. As a result of this action the pick strikes in the same plane each time consequently breaks the ice without undue chipping and with but little chance of the piece which is broken off being subdivided, it being noticed in this connection that the pick cuts more effectively and reliably because it has a draw-cut action, that is to say, while always striking in the same line it is permitted to play back and forth between the guide rods, a distance equal to the length of one of the slots, and it has been found in practice that because of this fact the ice is broken much more cleanly and reliably and with less waste of ice from chipping than is possible with a pick which has no such lateral or vibratory action. The fact that the handle is of considerable weight of course enables the operator to cut the ice effectively with short strokes of the pick and with the least possible exertion.

From the above description it will be apparent that we have produced an ice pick which embodies the features of advantage enumerated as desirable, and we wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

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

1. An ice pick, comprising an anchor-frame having two points of engagement with the ice, a stem extending slioingly through said frame in the line of said points of engagement, a pick in the form of a plate arranged in the same line as said points and secured to said stem, and a sliding connection between the pick and said anchor-frame whereby the former is retained in the line 'of said points.

2. An-ice pick, comprising an anchor-frame having two points of engagement with the ice, a stem extending slidingly through said frame in the line of said points of engagement, a pick in the form of a plate arranged in the same line as said points and secured to said stem, and a connection rigid with respect to the pick and mounted to slide longitudinally and laterally upon said anchor frame, the lateral movement being such as to impart lateral movement to the pick in the line of the points of engage ment of the anchor frame with the ice.

3. An ice-pick, comprising an anchor-frame having two points of engagement with the ice, a stem extending slidingly through said frame in the line of said points of engagement, a pick in the form of a plate arranged in the same line as said points and secured to said stem, and a cross-liar rigid with said pick and provided at opposite sides of the same with short longitudinal slots engaging said guide-frame to retain the pick in the line of saidpoints.

4. An ice pick, comprising an anchor-frame consisting of a centrally perforated cross-head and a pair of substantially parallel rods projecting from said cross-head and terminating in pointed ends, a stem extending slid ingly through the crosshead and provided with a handle at-the opposite side of the same from said rods and with a pick in the form of a plate, between said rods and provided with a plurality of saw teeth, and a cross-bar rigid with said stern and pick and-provided with longitudinal slots engaging said guide-rods.

In testimony whereof we afiix our signatures, in the presence of two witnesses.
