Be it known. that I, FRANK SAUCIER, a citizen of the United States, residing at Haines, in the Territory of Alaska, have invented certain new and useful Improvements in Means for Attaching Caps and Fuses to Stick Explosives, of which thel following is a specification.

- I This invention relates to explosives in a holein them for the insertion of the det-i Ona-ting cap. It istlierefore,. the common practice for miners and'other persons using explosives of this character, to thaw them out before'use, and they must be thawed to very near the danger point before it is pos-l sible to form a hole in them for the recep*v tion of the detonating cap. I

One of the important features of the present linvention consists in making a preformed hole inthe stick of dynamite or like explosive at the time of manufacture of Such stick and in making the hole of such configuration that a piece of fuse with the attached priming cap may be slipped thereinto but cannot be withdrawn therefrom by a direct pull.

A subsidiary feature of the invention re-A sides in making the said preformed hole of such configuration that it will be operative for the purposes intended, even though the stick of dynamite be cut in two, transversely.

Further objects and advantages of the in-V scription which follows.

In the accompanying drawing: Fig. l is a side elevation of a dynamite stick constructed in accordance with the invention;

Fig. 2 is a longitudinal sectional view therethrough;

Fig. 3 1s a rear end elevation thereof with.

a closure cap in place;

-heavy 'paper enc osinlg e Fig. 4 is, an end elevation with the cap removed; and y Fig. 5 is a sectional v iew upon the line 5 5 of Fig. 2.

Like. numerals designate .corresponding l. Y

parts throughout the several figures of the l drawing.

In the drawin 5 designates the usualv case, or wrapping, and 6 the more or such asdynamite or the more or less solid explosive, suchy as blasting powder. It makes no difference as far as the ,principle involved is concerned, what particular kind of explosive is contained in lthe casing5.' 70 In carrying out the invention,` I-,form in the explosive at the time of manufacture a hole 7 which extends longitudinally all the way through the stick and vopenings 8 which ex Vtends inwardly from the opposite ends` of the stick andjie in spaced relation `to the 'opening 7 the openings 8 being ,of `a depth to receive the cap ,9. Transverse oo ve's 10 formed in the :body of the explosive at the opposite ends of the stick connect the open- 80 ings 7 andS.

I, preferably, rovide removable caps or closures 1-1, V.wh'icili enter the open ends of the casing 5 and seal the same, but which l may be easily and quickly removed and replaced when it is desired to attach the fuse and cap to the explosive stick.

When the fuse and cap is to be attached to the stick, the closures 11 are removed and the fuse, with the cap 9 attached there- 90 to, is passed 'longitudinali through the stick through the opening. The fuse is pushed through a .suilicient distance to permit of its being given a return bend so that the cap 9 ma opening 8.v he fuse'12 is then given a,

reverse pull which causes lit to bind firmly 1n position and the cap 11 constitutin the inner or lower end of the stick is rep aced ound it is not and the char e is read for use.

When wor ing in ry absolutely essential that t e cap 11 be replaced,- but in working in wet ground, I contemplate using any suitable waterproofing material, such as tar, parailin or the like,

inserting the same in the open end of the casing 5 and thereafter replacing the cap.` If it be desired to seal the upper vend vof the stick, the cap at that end y be suitably notched for the passage of the fuse 12. Ha

be inserted in one of the 35 The purpose of providing two of the openings 8 is that the fuse may be inserted from either end of the stick and that there will still be an operative device, if the stick be cut in two transversely to form a half charge. find it is desirable to insert paper tubes. in the body of explosive material 6 during the process of manufacture, in order to aid in forming the holes. Some explosives are sufn ficiently sti" after manufacture to permit of the removal Aof these paper tubes, but it is to be understood that the invention contemplates leaving these tubes in position, when desired.

It will be seen that 'the present inventionv present invention, one man could do this work in a comparatively short time. It is a well known fact that workmen who have to spend considerable time in handling thawed powder and making the sticks ready for use as rimers su'er from severe headaches. My invention will in a large measure prevent this because of the very greatly reduced time required to do the work with the consequent reduction in the amount of handling of the dynamite required. f

vIt is to be understood that the invention is not limited to the particular construc- With some kinds 'of explosives E Lampes tion shown, because other ways of arranging the hole will readily suggest them* selves. The invention resides in providing holes into which the fuse andv cap may be slipped which are of such coniguration that a reverse pull upon the fuse will not serve to withdraw the fuse and cap.

Having described my invention, what l" claim is:

1. An explosive stick having an opening formed therein for the passage of a fuse cap and an additional opening' for the reception oi' the cap after the fusehas been given a return bend, said stick being provided with a transverse recess at its end for connecting said openings7 and a'retainingcasing for supporting the said stick.

2. An explosive stick having a fuse opening formed longitudinally therethrough and a pairof primer openings formed part way therethrough, the openings of said pair extending inwardly from theOopposite end of the. stick, said stick being provided with transverse recesses at its opposite ends for connecting said fuse opening and said prlmer opening.

3. An explosive stick comprising a retaining casing and a filling of explosive material there being a fuse receiving channel formed longitudinally entirely through said stick at one side 'thereof and a pair of openings extending longitudinally thereof one at each end of the stick and at the opposite side of the stick from said chan-l FRANK sAUcIER.
