A TTUHN E YS HENRY CURRIER, OF ROSE HILL, IGI/VA.; HARRY VYIJIURE ADMINISTRATOR OF SAID HENRY CURB/IER, IDECEASED.

FISHING-TOOL.

Lacasse.

Application filed December 11, 1919.

To all 'w hom t may concern Be it known that I, HENRY Comune, a citizen of the United States, and a resident of Rose Hill, in the county of Babaslra and State of Iowa, have invented certain new and useful Improvements in Fishing-Tools, of which the following is a specification.

My invention relates to grapples and has reference more particularly to tools for fishing dull bits and other implements from wells. l

An object of the present invention is to provide an improved device of the character which, upon being lowered into a well or other boring, is adapted to engage and hold the object whereby the same may be removed.

Another object is to so arrange the grappling tongsA and the jaws thereof that a variety of different objects may be readily removed from a boring.

With these and other objects in view the invention consists in certain novel features of construction and arrangement of parts as will be hereinafter set forth and pointed out in the claims, reference being had to the accompanying drawing, in which- Figure l is a front elevation showing one form of my invention as in use;

Fig. 2 is an elevation of the device with the front or face plate removed;

Fig. 3 is a side elevation of the device;

Fig. l is a vertical section taken as on line 4 4 of Fig. l;

Fig. 5 is a front elevation of a modified form of the device as in use;

Fig. 6 is a similar view enlarged and showing the gripping levers set for action;

Fig. 7 is a side view of the modified form; and

F ig. 8 is a vertical longitudinal section of the same.

Fig. 9 is a vertical longitudinal section taken on aline 9 9 of Fig. 7.

Referring in detail to the drawings and more particularly to Figs. l, 2, 8, and 4l it will be noted that I provide a body or stock portion comprising a face plate A and a baclr plate B spaced apart at the Aupper end by a spacer block C through which the bolts D pass, these bolts also passing through the face and back plates and through the stock hanger straps E E provided with the elongated slots e at their upper ends; nuts d Specification of Letters Patent.

are screwed on the ends of the bolts D and against the said straps, thus securing the face and back plates and the hanger straps E E together.

Between the face and bach plates a pair of levers F are disposed with their lower ends G projecting 1nelow said face and back plates, said levers having'the overlapped ears H with central perforations I through which the fulcrum member J passes, said fulcrum being a bolt which also passes through the elongated slots a and Z) in the face and bacl; plates, respectively.

The upper ends of the levers are pivotally secured to one end of links K, the other ends of said links extending on opposite sides of the clevis L in overlapped relation and between said clevis and the slotted hanger straps E l@ and there held by the bolt M and the nut m.

The crossing portions or ears H of the levers are cut out or recessed one-half their thickness so that the space between the face and back plates is the same as the thickness of the upper arms F of the levers.

T he lower ends of Vthe face and bach plates are provided with integral semi-circular flanges A and B tothe lower face of which are held semi-circular extensions A2 and B2 by means of bolts A3 and n3 eX tending from the flanges All and B1 through the open ended slots A4 and B4 in said extensions. rfhese extensions may be moved outwardly and held to accommodate the tool to the diameter of the boring in which the tool is working.

The lower ends of the levers are provided with parallel obliquely set ribs il or knurls on their opposite faces and to such faces are pivotally secured the curved jaws O 0 having corresponding parallel ribs or linurls by which the jaws can be adjusted to practically any angular position and held there by the bolts P passing through the lower ends of the levers and the said jaws.

The opposite side edges of the face and back plates near their upper ends are provided with the triangular shaped notches (d and @l into which project rigid studs or pins Q? and Q3 from the opposite faces of the upper arms F of the levers and in which notches the studs or pins have lateral play, their inward movement being controlled and limited by stops which consist of a flat plate Q4 having open end elongated slots therethrough and which are slidably and rotatably mounted on bolts against the front of the face plate adjacent the aforesaid notches which are reentrant. By moving these stops inwardly or outwardly or swinging themen their pivot the throw of the levers can be controlled .and hence the eX- tent of the opening of the jaws at the lower ends also controlled.

A cable or rod is secured to the upper end of the clevis L and by this cable the tool is lowered into the boring with the jaws G spread apart as in the position shown in Fig. 2, the links li being horizontal and the bolt connecting them, the clevis and the hanger straps, lying within the extreme lower end of the elongated slots of the said hanger straps. l/Fhen the lower end of the stock comes in Contact with the bit or article to be fished from the boring, the cable is given an upward jerk or pull whereupon the clevis is pulled upward carrying the bolt M up to the upper end of the elongated slots causing the links to draw inwardly the upper ends of the levers and closing the jaws on the article and grip it between them where it is gripped and held by the serrated or sharp ends of the gripping jaws. rl`he bit and this tool can now be lifted out of the boring.

rEhe device just described can be used in a plain boring, or it may be used in a well casing, as indicated in Fig. l.

1n Figs. 5, 6, 7 and 8 a modified form is shown and which comprises a stock or body portion consisting of a plate R having at its lower end an integral horizontal flange r, a reduced portion r at its upper end in which reduced portion an elongated slot r2 is made and also provided at its central portion with an elongated slot Adjacent the lower end of the stock a pair of cross levers S S are pivotally mounted and held by a headed bolt 'l which passes through a bulge or enlargement s on the lever S the head of the bolt being seated in the countersunlr or depression s2 in said bulge thence through lever S and stool: R and the nut s3 on the bolt binding against the stock and resting on the flange r by which it is prevented from turning off, thus constituting a nut lock.

The levers S and S where they cross are recessed or cut out so that they present ay uniform thickness throughout their length.

The upper ends of the levers S and are recessed or cut out on opposite sides st et and in these recesses are pivotally mounted the lower ends of the toggle links U being secured to the upper ends of the levers in said recessed portions by bolts u and secured at their crossing to the reduced upper end of the stock by the bolt u said bolt u also serving as a means of securing the suspen- :incense sion means of the device, which `consists of a plurality of strap sections V the adjacent ends overlapping and bolted together after the manner of a folding rule. The bolt u passesthrough the elongated slot r2 in the upper end of the stock, and the lowermost section V of the suspension means is slidably secured to the back face of the stock by the bolt 'a2 which passes through the elongated slot in the central portion of the stoclr, a washer us being placed on the bolt between the s'toclrand the lower section of the folding suspension means; the slots r2 and r3 are in vertical alinement and a washer u3 is also placed on the bolt u between the stock and the said suspension section, all as plainly seen in Fig. 8.

llhe lower or jaw ends W of the levers are curved and are provided withV gripping means which in the present instance consist of hardened pointed screws X threaded through the jaws from the side edges in an oblique direction with the points projecting upwardly and inwardly through the inner edges of the jaws. These pointed screws, which, it will be noticed, form teeth, can be adjusted to any degree desired so as to grip a large or a small article or tool which may have become broken or dropped into the bottom of the boring.

In using this form of device for fishing it is lowered into the boring or casing with the parts in the position shown in Fig. 6, the suspension device being folded out and extended to its full length. Upon reaching the bottom or coming in contact with the tool or article to be fished, the suspending means is given a quick jerk upwardly which causes the crossed levers to close scissors-like, the bolts al and u2 rising to the upper ends of the elongated slots r2 and r3 and drawing the upper and lower ends of the crossed levers to swing toward each other and the pointed screws X to bite into and grip theV article, as shown in Fig. 6. The entire Vdevice vis then pulled upwardly from the boring or casing and the article released from the gripping jaws.

I claim:
