BLANK fcAR'InInG-E. l' i Appiiaaon iearnovember' 3 0, lezzseiai no zsezfi, and Belgium Nv'ember 3o, 19;@ 2 Y VThis invention has reference to' improvements V1n or relatlng to blank cartridges for use with rearms and is more particularly' concerned with blank cartridges for use with Y 5 Asmall arms of the kind in which the ejection of the empty cas-e and the loading Oia-new cart-ridge is eflieoted by thebackward and forwardrmotion of the bolt. 'I
In order that eachhring of a blank cartridge may be complete itis necessary thatv Y the re-coil produced by the discharge'of thev 'dummy bulletshould be sufficient to ensureY the automatic ejection ofthe empty case.
Heretofore it has been proposed to solve thev 115 problem by increasing theweight of the icartridge by `partially granular substance.'
The present invention'solves the sameproblem by employing` asa charge two explosives 0i different degrees of iniiammability the Y slower burning powderv preferably being dis'` ,posed in close proximity to the dummy bulletv or the like which contains it. Y
The difference in the degree of activity between the two powders produces anv appreciablerecoil without affecting in anyway the vdischarge of the dummy bulletor the'pulver- 'ization thereof after leaving the barrel.
The drawing appended hereto shews in longitudinal vertical section and by way of example one means of carrying the invention into effect. y
The blank cartridge shewn in the drawingV comprises a hollow dummy bullet 1 which is r made inthe usual manner and of [any suitable materiahs'aid dummy bullet being iilled with ya relativel slow `burning powder 2.- This? ilet is inserted in a oase 5' which is l ing a oase,`a hollow dummy bullet insertedgin dummy bu filled with a. powder 4 said powder 4; being `of a relatively quickerburning quality than the powder 2 filling the'dumniyxlo'ullet f The` cartridge is provided with-the u'sualpercussion cap vordetonater whichis denoted byftlnev The charge of powderf4 forlling the case may itself, if desired, be made of two powders f tridge.v
