This invention relates to an ice pick.

In delivering ice by trucks, wagons, etc., it has been found by actual experience that the ice changes in hardness, as time passes, hence for reatest satisfaction in delivery, a peculiar pick is needed for use in cutting the ice, under changing conditions.

Therefore, .an object of this invention is the construction of a simple and efiicient ice pick, which can be used with the greatest satisfaction under the changing conditions of the conveyed ice.

Another object of the invention is the construction of an ice pick which has as unitary parts thereof a plurality of blades with points of varying sharpness.

A still further object of the invention is to provide a handle With a novel detachable head or plug, for supporting efficiently each blade upon the handle, as the operator requires.

This ice pick is an improvement upon the device disclosed in my prior United States Patent No. 1,956,875, issued May 1, 1934.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in theaccompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure l is a view partly in elevation and partly in section of the handle and head or plug of an ice pick constructed in accordance with the present invention, showing one of the blades carried by the head.

Figure 2 is a view in elevation of the head with a blade having the sharpest point for cutting hard ice.

Figure 3 is a view in elevation of the head with a blade of a blunter character, or less sharp point, than that shown in Fig. 2, for use on the ice as it becomes more tempered or softer, while Figure 4 is a similar view of the bluntest or less sharpened point blade for use on the ice as it becomes more soft, or honey-combed or white ice.

Referring to the drawing by numerals, I designates a handle which is provided at its outer end with a cylindrical socket 2. Around the outer end is preferably a metal band 3 for strengthening the socketed end.

The improved and novel head or plug 4 comprises the annular grip 5 integral at one side with the long primary cone 6, and at its opposite side with the short auxiliary cone 1. In the head 4 is a suitable socket 8 into which extends the inner end of the blade; in Fig. 1 I have preferably shown a blade 9 which is also illustrated in Fig. 2. This blade 9 is what might be called a long slim blade, being of the greatest sharpness for cutting hard ice, as the ice is first handled in the plant or delivered to the trucks and wagons. When the head is assembled with the handle I (Fig. 1) the long primary cone extends into the cylindrical socket producing a bearing In at the outer end of the socket 2, on the cone 6, whereby, as the operator cuts the ice the blade is permitted to slightly move, in different directions, as illustrated by the dotted lines A and B of Fig. 1 which produces an effect like a universal joint; this little give", in any direction, reduces the breakage of blades to a minimum, whereby their usefulness is greatly increased; this has been found to be true from extensive experience with a full sized working device, constructed in accordance with this invention. Of course, it will be understood that with each stroke of the pick, the head is wedged in tightly, but by reason of its small bearing II), it is allowed to give for producing the action clearly indicated by dotted lines A and B.

I have found that when the ice is fresh and hard right out of the plant, it requires a long slim blade (Figs. 1 and 2) to cut it or break it. Then after it has been hauled for a while outside, the ice becomes tempered or a little softer and requires a blunter blade ll (Fig. 3), as such blade goes into the ice deeper. Then as the ice gets softer or honey-combed it requires a still more blunt blade I2; in other words, it requires three styles of blade to satisfactorily deliver a big load of ice. With the handle I and the three blades 9, H and I2, of different sharpness or taper, one can get along without breaking the pick blades, because what breaks so many points of blades is this: the ice softens as it is hauled around and the blades sheer off to one side and the steel is so hard that it will not bend, hence the blade or blades break; by using my improved and novel head the primary cone gives the proper assembled result as well as the universal movement shown by dotted lines, for maximum efficiency.

The operator can quickly make changes of blades, owing to the detachability of the novel head, from the handle, and by reason of the novel and peculiar structure of the entire device, it has been found from extensive experiment and practical use that a very efficient ice pick has been invented.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawing, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. As a new article of manufacture an ice pick comprising a handle provided at one end with a cylindrical socket, a head comprising an annular grip and an integral long primary cone extending from one side of said grip, an integral auxiliary cone extending from the other side of said grip, said long primary cone extending into said cylindrical socket,said socketed portion of the handle forming a bearing on said primary cone at the outer end only of said socket, whereby the primary cone is permitted to have a slight universal movement in said socket, and a blade extending into said head, substantially as shown and described.

2. As a new article of manufacture, an ice pick comprising a handle provided with a cylindrical socket, a head provided with a cone, said cone extending into said cylindrical socket and normally only bearing against the outer end of said socket, and a blade mounted on said head.

3. As a new article of manufacture, the combination of a handle provided with a cylindrical socket, a series of blades of different sharpness, a. similarly constructed head on each blade, said head provided with a long cone, and said cone adapted to be positioned in said cylindrical socket, whereby a small bearing is produced, allowing of slight varying movements of the head on the handle during the operation of the device.
