Application September 2, 1949, Serial No. 113,698

2 Claims.

This invention relates to a combined pick and chisel for use in breaking out blocks of ice from a frozen body of water, such as a lake.

The primary object of this invention is to provide a handy tool for sportsmen in winter fishing through ice, which is sturdy, which can be readily assembled and disassembled, and which includes both a pick for making a hole through ice and a chisel for enlarging the hole and cutting the block of ice.

A further object of this invention is to provide a tool of the character described wherein the chisel may be readily removed when one wishes to employ only the pick, and which is also constructed in a manner which allows the pick to be carried and concealed in a support while the chisel alone is to be employed, thus rendering the tool safe for its intended operation.

These together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure 1 is a side elevational view of the assembled tool, the chisel being shown in perspective;

Figure 2 a longitudinal sectional view through the tool, some parts being broken away and others being shown in elevation; and,

Figure 3 is a group view in longitudinal section of the various parts of the tool, the pick being shown in a shielded position.

Specific reference'is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout. v

The present tool is to be employed primarily for chopping ice in a body of frozen water, such as a lake, and consists essentially of an elongated pipe section ill of suitable rigid metal such as steel, the pipe including external threads l2 and [4 at the free ends thereof. A chisel I6 is provided having a beveled cutting edge [8 at its bottom end and welded to its top end is a collar 20 which is internally threaded as at 22 for removably attaching the chisel to the lower end of the pipe section Ill.

A second elongated pipe section 24 is provided which has external threads 26 and 23 at the free ends thereof. Received within the upper free end of the second pipe section 24 and welded or riveted therein is a tapered pick 30, the pick being either round or square and having a piercing point 32.

The pick and second pipe section or tube 24 are removably retained upon the first pipe section Ill by means of a coupling 34 which carries an eye or hook 36 to which may be attached a rope 38 that may be appropriately anchored or secured at its other end to a suitable support. The coupling 34 includes internal threads 40 for removably receiving the external threads l4 and 28, and internal threads 42 for removably receiving the external threads 26.

' In practical operation, the chisel I6 and pick 30 may be secured to the pipe section In by means of a coupling 34 in a manner that will be readily understood by those skilled in the art. If it is desired that the chisel alone is to be used,- the second pipe section or tube 24 may be removed from the coupling and reversely attached thereto in the manner shown in Figure 3 wherein the external threads 26 are made to engage the internal threads 42 of the couplings so that the pick 30 extends within the pipe section It so that the overall effective length of the pipe section l0 and 24 may still be employed to get proper chiseling action while the operators hand is prevented from contacting the pointed end 32 of the pick. Furthermore, to make the entire tool easily transportable with safety, the chisel It may be removed from the bottom end of the pipe section I0 and carried with the remainder of the parts of the tool in the form shown in Figure 3.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in; this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims. Having described the invention, what is claimed as new is:

1. An ice chopping device comprising a first pipe having externally threaded ends, an ice chisel having an integral internally threaded collar removably engaging one of said threaded ends, a second pipe having external threads on one end thereof, an internally threaded coupling joining the other threaded end of said first pipe with the threaded end of said second pipe, and an eye hook carried by said coupling and adapted to engage an anchoring rope.

Y 2. The combination of claim 1, wherein the other end of said second pipe is externally threaded and adapted to hold an ice pick.
