yMy invention relates-to ldevices for chargf zing drill holes in mines 'and quarries with I Q blasting powder, or other explosives,` for thepurpose of blastingoutcoal, ores, Vrocketc., and my object is'to providea simple, inex# r`@pensive and efficient device of this character {.gwhereby said drill f h'olesinay be charged y15 morequickly and at less expensethan here- .tofore.-k .r f Inthe Apresent 'method of' charging drill holese specially those-extending inra hori' zontalor A inclined plane,itis customary to form a sort of cartridge Vof a sizeto enter '"thegholejby--l wrappingpaper Varound* the l blasting powder.
