4 Claims.

My invention relates to tools used in connection with blasting.

My object is to provide a tool which will enable the user to split fuses, crimp caps, and otherwise facilitate blasting operations. Other objects will appear as the description progresses.

Figure 1 represents a side view of the device open; Fig. 2, a side view showing the device closed and the blade in position to be used as a knife; and Fig. 3, a side view showing the device closed.

Although I show the preferred embodiment of my invention, I do not thereby limit myself to the precise form shown, but wish it understood that within the scope of what hereinafter is claimed, various changes in the precise details of construction may be made without departing from the spirit of the invention.

A pair of curved bars A and B are pivotally connected by a pivot P. The bar A has a handle 2 and a head portion 3. The bar 13 has a handle 4 and a head portion 5. A spring 6 is disposed between the handles 24 and held in place by studs l8 on the handles 2-4, respectively.

A blade holder 9 is provided with a journal H] which is mounted in the head portion 3 and held rigid by a thumb screw l I. A removable blade [2 is disposed in the blade holder 9 and held in place by thumb screws 13-44. The blade holder 9 is also provided with transverse grooves [-46.

The head portion 5 is provided with transverse grooves l1 and I8 which cooperate with grooves [5-46, respectively, to crimp caps. The head portion 5 is also provided with a fuse holding transverse groove 3| and with fuse holding chambers l9-20-2l and a plunger chamber 22.

A plunger 23 is disposed in chamber 22 and a spring 24 is disposed around the plunger 23 and serves to hold the plunger 23 away from the channel I9. The plunger is operated against the spring by a wedge member 25 connected to the head portion 3 of the bar A. Caps 30! are disposed on the pointed ends of the handles 2-4 to protect the clothing when carried in the pocket.

When a fuse 26 is disposed in the chamber 2|, and the handles 2-4 are squeezed towards each other, the fuse is split snake mouth style from the end. When a fuse is disposed in chamber 20, and the device closed, the fuse is split the side out style, the blade l2 cutting just through the powder channel.

Normally the spring 24 holds the plunger 23 away from the chamber [9, but when the handles are squeezed towards each other the wedge member 25 forces the plunger 23 towards chamber I9 and against the fuse 21 snugly while the blade l2 splits the fuse.

If a fuse is laid in the transverse groove 3| in the head 5, the fuse can be trimmed squarely on the end. The blade holding member 9 may be swung to the position shown in Fig. 2 so that the blade can be used as a knife. The handles are pointed so as to be used to punch holes in powder for lacing the fuse and inserting the cap or primer.

1 claim:
