7 Application filed October 16,1902. Serial No. l27, l6. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH FIsoHLER, a citizen of the UnitedStates, residing at Silverton, county of San Juan, State of Colorado, have invented an Improvement in Fuse-Splitters and Oa'p-Crimpers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device which is especially designed for splittingfuse and cri mping caps upon the ends thereof in readiness.

. which the blade for use;

It consists of a pair of handles pivoted together, the operating end of one: consisting of afu's'e-splitting blade an'daone-half of the crimping segment, and the operating end of the other handle carrying the elasticallymo'unted splitting-blocks in conjunction with operates and also carrying the other half of the crimper. The side walls of the splitting-blocks may also be formed to receive the fuse transversely, so'thatthe same bladew'ill serve to cut it into desired lengths.

Referring to the accompanying drawings, Figure 1 is a side view showing the device open. Fig. 2 is a section on mm of Fig. 4. Fig. 3 is a cross-section on the line y 3/ of Fig. 4, showing the splittingblocks with their spring sides or extensions and attachment to thejaw. Fig. 4 is a side view with jawsclosed.

It is the object of this invention to provide a convenient tool by which all the work of preparingfuse and afiixing the explosion-caps thereon may be easily efiected.

As shown in the drawings, A and B are handles crossing each other and pivoted together, as shown at O. The extension of one of these handles A beyond the pivot-point is formed intoa sufficiently-thin sharp blade 2. The extension of the other handle B carries the jaw, in conjunction with which the blade 2 may operate, first, to cut oil? the fuse and make a clean square cut to fit the cap and after loading the hole to split the fuse a short distance from the end, and thus prepare it for ignition. The splitting-block consists of two elastic blades 3, the lower ends of which are riveted or otherwise secured to the lower end of the extensionB of the handle B. These sides 3 3 extend upward and have formed near the upper ends the inwardly-projecting blocks or surfaces 4, which nearly or quite meet each other centrally between the sides 3, leaving a space into which the blade 2 may descend,

the sides 3 3 being sufficiently elastic .to allow the blocks to separate as the bladepasses between them and to again close together when the blade'is removed by opening the jaws. Above the blocks 4 the sides 3 extend, as at 3, forming guides between which the fuse is held centrally when the end is inserted for the purpose of being split. These sides 3 also have formed in them the semicircular grooves 5, which are transversely in line with each other and the bottoms of which are flush with the surfaces of the blocks 4:. This allows the fuse to be laid into the grooves 5 transversely of the blade 2 and supportingblocks 4, and when the handles are closed together the blade will cut the fuse squarely across, because it lies solid on both the blocks 4, and being equally supported the blade passes squarely across and into the space between the blocks, which are slightly separated by the movement.

, This square end of the fuse is then ready to beinserted and secured within the cap as follows: Behind the blade 2 and the opposing jaw 4 the semicircular transversegrooves 7 are made in the two jaws opposing each other, so that when closed together they will form an essentially circular hole transversely through the twojaws. Within these jaws the cap is placed, the fuse fitted into the end of the cap, and by closing the handlesthe cap will be criinped firmly upon the end of the fuse and the connection will be waterproof. After the hole has been loaded the projecting end of the fuse is split, so that it may be quickly ignited, which is necessary when a number of holes are to be fired at once. To do this, it is laid lengthwise between the upwardly-projecting sides 3", and is thus held centrally in place. forced down by closing the handles passes through the fuse and into the space between theblocks 4 as the handles are closed, thus splitting the fuse cleanly and evenly. As soon. as the blade is withdrawn by opening the handles the blocks close together again.

In order to limitthe rearward movement of' the fuse, and thus prevent its going beyond the splitting-block, I have shown a block or stop 6, which projects upwardly at the rear end of the blocks 4 and inline with the open The blade 2 being thenporting,

plane efmnv' the other, elastic'plates fixed to said jaw, separable blocks carried by'said plates and guides extending above the hlocks','and a stop at the inner end of the splitting-block against which the fuse-abuts when being split.
