SNOHOMISII, VASHINGTONF TOOL FVOVRMMINERS AND BLASTERS use.
SPECIFICATION forming part of Letters Patent No. 463,912, dated November 24, 1891.
Application 513a June 9,1891. Serial No. 395,651. (No model.)
.To all whom it may concern:
Be it known that I, RICHARD ALAXANDA MOVITTY, of Snohomish, in the county of Snohoinish and State of \Vashington, have in vented a new and Improved Tool for Miners and Blasters Use, of which the following is a full, clear, and exact description.
My invention relates to a tool especially adapted for miners and for blasters use; and the object of the invention is to provide a combination-tool comprising all of the implements necessary for use in the treatment of fuses or for the attachment of caps to fuses or for inserting the capped fuse in a car'- tridge.
A further object of the invention is to provide a tool of exceedingly simple and durable construction, and one capable of being expeditiously and conveniently manipulated and also occupying but a minimum of space.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.
Figure 1 is a bottom plan view of the tool. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation. Fig. 4 is a longitudinal section on the line a: a; of Fig. 1. Fig. 5 is a transverse section taken on the line 3 yof Fig. 3. Fig.6 is a side elevation of a portion of one of the handles. Fig. 7 is a side elevation of a fuse provided with a cap, the latter being in section; and Fig. 8 is a plan view of a fuse, illustrating one end compressed to enter a cap.
The tool in general appearance resembles a pair of tweezers or a like implement, comprising two pi votallyattached members A and 13, each member consisting of a straight head .10 and a curved shank or handle 11. The handles of the members A and B are normally forced apart, whereby the heads of the members are kept in like position through the medium of springs 12, secured at one of their ends to the inner faces of the handlescction, and the other ends of the springs are interlocked at a point opposite the pivotof the members.
l- The handle section or member B at its extremity is bent outward at an angle, as illustrated at a, and is flattened and sharpened at its point to constitute a screw-driver 13 or a blade for prying open the lids of boxes. At the extremity of the opposite handle-see tion 11 a cavity is formed, as illustrated in Fig. 6, which converts said extremity into a tack-puller 14. hen it is desired to lock the heads of the two members together, it is eifected through the medium of a lin 15,pivoted to one of the handle members, preferably to that terminating in a tack-puller, the opposite end of the link being adapted to pass over the extremity of the handle-section formed as a screw-driver. Thelink also serves as a means whereby the tool may be hung up or suspended from a belt when not in use.
Near the pivot of the tooland in the handlesections of the members recesses are produced, in which recesses cutters 16 are fitted, being This removable attachment is eflected in order thatthe cutter may be taken out and sharpened when occasion may demand. The cutting-edges of the cutter-blades 16 extend a sufficient distance beyond the inner side surcutting-edges to engage without entirely closing the space between the heads of the members. The cutters 16 are employed for trimming the ends of fuses, or may be used for any other desired purpose. At opposite sides of the pivotal connection of the members semicircular recesses 17 and 18 are produced in the outer edges of the members, the recesses 17 aligning, and the recesses 18 practically so, when the handle-sections are forced apart. These recessed surfaces at their engaging edges are so sharpened as to form cutters, the recesses 17 constituting cutters to receive a fuse and sever it completely when the handlesections are brought toward each other, and the opposite recesses 18, which are smaller, may be employed for cutting wire or any other desired article.
In the upper face of the head-section of the member B a horizontal recess 19 is produced, in which a spring 20 is located, and a knife 21 is pivoted in the recess, the pivot end whereof engages with the spring 20. Thus when the knife is closed in the recess the held in position by screws or theirequivalents.
faces of the handle-sections to cause the said the said blade being of sufficient width to extend nearly to the wall of the opposite groove when the heads are brought together, as is illustrated in Fig. 5. The grooves and the knife 23 are adapted one to receive the end of a fuse and the other to cut the end, as illustrated at b in Figs. 7and S, to facilitate lighting the fuse.
In the inner face of the head-sections of the members two transverse recesses 2i and 25 are made. The recesses El and 25 are in each head and differ in shape. The recesses 2% are semicircular and of one diameter for the major portion of their length. Near one end, however, the recesses are reduced in width, as illustrated at (Z in Fig. 4, and the object of thus reducing the recesses 24 is to crimp ribs (1'. upon a cap (1 and thus fasten the cap upon a fuse. Thus the recesses 24 may be properly denominated cap-setting recesses.
The recesses 25 are tapering, and their object is to reduce the end of a fuse by compressing it, as illustrated at d in Fig. S,'s'o' as to enable said end to be inserted in a cap in the event the fuse is larger in diameter than the cap. The blade 21 may be used for any purpose requiring such an instrument, but is especially applicable for cutting cartridges, so that the capped end of the fuse may be inserted therein.
Each head-section is provided with a down- In one of the wardly-extending lug capable of use as a hammer, the said lugs being best illustrated at (Z in Figs. 1 and 3. The inner facesof the headsect-ions'of the members may be serrated or otherwise roughened,if in practice'itis found desirable, so that to an extent they may be utilized as nippers.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a miners and blasters tool, the two pivoted membersA B,having handles 11 and jaws 10, a recess 19 in the side face of one jaw, a spring 20 along the inner longitudinal edge of the recess, and the knife-blade 21, pivoted in the forward end of the recess, with its heel in engagement with the spring, substantially as set forth.
2. A tool for miners and blasters use, consisting of two pivoted spring-actuated members provided with cutters of different shapes and sizes adjacent to their pivotal points, longitndinal recesses in the inner faces of their head-sections, one of the recesses being provided with a' removable blade, lugs projected downward from the head-sections of the members, and a link adapted to close the handleseetions of the members and serve as a suspension device, as and for the purpose set forth.
3. A tool for miners and blasters use, consisting of two pivoted spring-pressed members, the head-sections whereof are provided upon their inner faces with aligning, tapering, transverse recesses, and semicircular transverse recesses reduced in diameter near one end, substantially as shown and described, and for the purpose specified.
