FISHING-TOOL.

Specification of Letters Patent.

Patented Dec. 5, 1916.

AppIication filed. August 5, 1916. Serial No. 113,290.

To all whom it may concern.-

Be it known that I, ROBERT B. WHITE- smn, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Fishing- Tools, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention consists of certain improvements in fishing tools and relates particularly to such tools designed for the recovery from the hole of lost or detached portions of hole drilling devices, such as are used in the art of mining.

The object is to produce such a tool having improvements and advantages over similar tools used for a like purpose.

Another object is to produce such a tool that will maintain its relative position in the hole automatically.

Still another object is to produce such a tool having the ability to hold a lost article in suspension and still permit of its altering its position in the jaws of the recovering tool as the latter passes upwardly within the drill hole.

Other objects and advantages of my improved tool will appear in the further description of the device.

In the accompanying drawings forming part of this application, and in which like reference numerals indicate like parts, Figure 1 is a side elevation of my assembled fishing tool. Fig. 2 is an inside face view of the rigid finger 0f the tool and, Fig. 3 is an inside face view of the resilient finger of the tool.

1 represents the shank portion of the tool, it being squared in a portion thereof, as at 2 for the application of wrenches, such as used for similar tools, and upon the upper end of the shank 1 and formed integral therewith is the tapered screw threaded member 3 and by which the tool is secured to the ordinary drilling stem, such combination being well known in the art.

The lower end of the shank has formed integral therewith a long tapered finger 4, at the upper end being equal to approximately one half the size of the shanloand at its lower end terminating in substantlally a sharp point. The outer wall of thls finger is of a rounded form, looking axially thereupon, and is as if out from a solid cylmdrical piece of metal, the inner wall or face 5 belng perfectly flat, and inclined from the shoulder 6 t0 the point 7.

Between the shank 1 and shoulder 6 there is formed transverse the face of the finger 1 one or more transverse grooves 8 into which are designed to fit the ribs 9 formed on the upper end of the face 10 of the cooperative resilient finger 11.

The resilient finger 11 may be of any deslred form in cross section throughout except at its uppermost end, where it coincides with the cylindrical form of the shank 1 and is attached to the base of the rigid finger 4 through the interlocking grooves and ribs 8-9 by suitable bolts or rivets 12 in the registering holes 1314. 'The resilient finger 11 is considerably shorter than the finger 4 and approximately one third its length up from the free end is formed with an outwardly projecting hump or convex portion 15, the outer face of which is designed to normally engage the wall of the hole as the tool is reciprocated therein.

The hump 15 is for gaging the width of the jaws of the tool and keeping the rigid finger normally well over against one side of the hole to insure the point thereof striking as nearly as possible one edge or corner of the lost article in the hole and thereby turning it on edge to be subsequently forced in between the jaws of the fingers as the end of the finger l is forced on down past it into the muck, usually found in the bottom of a hole being drilled.

The extreme lower end of the finger 4: is cut off squarely, forming the fiat end thereof and if desired, the face of the finger adjacent the extreme end may have serrations formed therein to further catch and assist in upending the article to be recovered, as the finger may be in the act of passing said article.

The extreme free end of the spring finger 11 is inclined upwardly and inwardly as at 16, to guide the object sought.

The jaw portions 17 and 18 of the respective fingers 1 and 11 have formed therein rasp-like serrations with the engagmg points pointing upwardly to firmly hold any object thrust therebetween, and this rasp-like surface being of considerable extent will hold an object even though it is forced to move about therein considerably in coming up through the hole.

fingers land 11 issuch that the tool snugly fits within the hole for which it is designed 5 and having an appropriate space between the j'aws'17;18, for the purpose intended and if the object sought is forced up be 7 tweenithe jaws,it is held there principally by :the resiliency in the spring finger between the hump'15 and the extreme free end of the spring finger, by virtue of the fact that the hump will forcibly impinge the wall of the hole as before stated.

Having thus described my invention what I claim and desire to secure by Letters Pat- 'entis:, l

V '1. 'A fishing tool of the character described, comprising a shank portion, a rigid tapered finger, a resilient finger, and means upon; the resilient finger for' maintaining axial alinement of the tool within the hole. 2-. The combination with a fishing tool havingtwo cooperating gripping members, one beingfconside'rably longer. than the "other', of means upon the shorter member Copies of this patent may be obtained for for, keeping the longer member snugly against the wall of the hole.

3. A tool of the character described comprising a shank portion having formed integral therewith a long tapered gripping and upending finger, a shorter gripping spring finger rigidly fixed to the tapered finger, gripping surfaces upon each of the fingers opposite each other and means upon the shorter finger for keeping the tool in proper alinement within the hole.

4:. The combination with a fishing tool having a shank portion and two cooperating gripping members, one being rigidly fixed to the shank portion and longer than the other, of means for resiliently keeping the rigid member against one side of the hole.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
