MINERS FUSE PLIEBS.

Application filed June 15,

To all whom it concern:

Be it known that we, JOHN YOUREK, J12, and STEPHEN YOUREK, citizens of the United States of America, residing at Thayer, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Miners Fuse Pliers, of which the following is a specification.

This invention relates to miners tools, and has special reference to a miners fuse plier.

One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improved form of fuse plier wherein novel means is provided for splitting the fuse, cutting it oil? and splitting it at the knotted part thereof.

A third important object of the invention is to provide, in one tool. means for cutting and splitting the fuse either at its end or in the knotted part. means for crimping the dynamite caps used therefor, and means l for cutting the paper used by miners to wrap fuse ends and charges of powder and the like.

WVith the above and other objects in view as will be hereinafter apparent. the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specificallv claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Fig. 1 is a side elevation of a pair of fuse pliers constructed in accordance with this invention, one position of the pliers being indicated in full lines, and a second position being indicated in dotted lines;

Fig. 2 is a cross-sectional view through the handles of the pliers in their closed position, the view disclosing the can crimping device;

Fig. 3 is a detail perspective view of the lower jaw of the pliers showing the parts separated and;

Fig. 4 is a transverse section taken through the jaws in their closed position.

In the embodiment of the invention herein illustrated, there is provided a pair of members pivotally connected at 10, and one of these members has a jaw 11 and handle 12, while the other is provided with a jaw 1923. Serial N0. 645,623.

13 and handle 14. The jaw 11 is longitudinally channeled as at 15, and carries a cutter blade or knife 16 which extends longi tudinally of the jaw and upon closing of the pliers will be in a space 17 formed in the opposite jaw. The side walls of the jaw 11 are transversely grooved as at 18, the groove intersecting the knife blade so that fuse may be received therein and cut by said knife blade. The outer end of the jaw 13 is laterally reduced on each side as at 19, and also is cut away at the bottom to provide a shoulder 20. This rabbet 20 receives a plate 21 forming the base or attaching means for a pair of spaced side walls 22. which are so arranged that they fit closely against the sides of the reduced ends 19.

In order to prevent longitudinal movement of the member having the side walls 22, the plate is apertured for the passage of a suitable screw 25 which passes through the plate 21 into the underside of the jaw 13, as shown in Fig. 1. Projecting toward each other from the side walls 22 are flanges or concave seats 26 which engage over the top of the reduced portion 19, and are spaced to provide a slot 27 wherethrough the knife 16 may pass. On one of the handles, as 12, there is provided a projecting portion having an arcuate recess 28. while on the other handle is an opposed crimping member 29 so that after a cap has been fitted. on the end of a length of fuse, it may be placed in the socket 28 and crimped by the member 29. The extremities of the handle portions are suitably arranged for other operations, and to this end the extremity of the portion 14 has a section 30 formed of brass, cop per, or the like, which is a non-sparking metal under the conditions of miners use, and the end of this section is secured to the body of the handle as by dovetailing 31. The other end from the dovetail of the section 30 is formed with a sharp edge 32, so that it may be used for opening powder cans and the like with safety. The other handle 14 is provided with a sharp cutter roll 33 which may be used for cutting the paper commonly used by miners. It will be noted that the upper sides of the flanges 26 are concave in form so that they can properly support a fuse end for splitting by the blade 16.

The knife or blade 16 and the shoulder 19 means for cutting a length of fuse, in the blade and slot means for splitting the fuse end, in the slotted jaw means for splitting the knotted portion of the fuse, it being common to knot the latter before inserted in the powder. Also this tool provides means for opening powder cans with safety,

means for crimping caps and means for cutting paper.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form. herein shown-and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the what is claimed as new, is:

1. A miners fuse pliers consisting of a pair of pivotally connected members each having av jaw at one end and a handle at the other, one of said jaws being provided with a longitudinal cutter blade and the other jaw being provide with a. longitudinal slot to receive said blade upon the jaws being closed, said slot-provided jaw being reduced at its outer end, and a second slotted jaw removably mounted on said reduced end.

2. A miners fuse pliers consisting of a pair of pivotally connected members each having a jaw at one end and a handle at in venti on,

the other, one of said jaws being provided' with a longitudinal cutter blade and the other jaw being provided w1th a 10ngitudi nal slot to receive said blade upon the jaws being closed, said slot-provided jaw being reduced at its outer end, a removable sl0tted membe having a supporting plate engageable with the back of the slotted jaw and provided with spaced portions ar ranged parallel to and on opposite sides of the slot, said spaced portions fitting closely against the sides of said reduced portion of the jaw.

3. .A miners fuse pliers consisting of a pair of pivotally connected members each having a jaw at one end and handle at the other, one of said jaws being pro videdwith a longitudinal cutter blade and the other jaw being provided with a longitudinal slot to receive said blade upon the jaws being closed, said slot-provided jaw being reduced at its outer end, a double member having a supporting plate engageable with the back of the slotted jaw and provided with spaced portions arranged parallel to and on opposite sides of the slot, said spaced portions fitting closely against the sides of said reduced portion of the jaw, and pro- VlClBClWltll opposed internal shoulders fitting over the top of the reduced portion of the jaw and spaced to permit passage of the first cutter blade therebetween.

.4. A miners fuse pliers consisting of a pair of pivotally connected members each. comprising a jaw portion and a handle portion, one of said jaws being provided with a longitudinally extending single cutter blade, the other of said jaws being provided with a slot for receiving said blade and supporting a removable pair of longitudinally extending fuse supporting members at its end, a cap crimper between the handle portions, and a roller journaled in the end of one handle portion.
