Improvements in Cartridges.
I, HERMANN GÜTTLER, of Reichenstein, Silesia, Kingdom of Prussia, German
Empire, Manufacturer, do hereby declare the nature of said invention to be as
follows:-
Priming caps or detonators are usually defective as regards the quality and
uniformity of the detonating compound or priming. It is not practicable to obtain
uniformity in the detonating compound or priming because it is employed in making
the cap or detonator in a moist condition and cannot be exactly weighed and there-
fore the caps or detonators more particularly those employed in sporting rifles
cannot be adjusted with sufficient precision to exercise a uniform action upon the
charge in the cartridge and especially is this the case with certain classes of
smokeless powder which do not readily detonate, such as plastomenit. The conse-
quence is inefficiency, in effect, and it is the object of the present invention to
remedy this. This invention consists in inserting between the cap or detonator and
the charge an intermediary primer consisting of a predetermined quantity of
explosive substances or substances correctly weighed while dry, and the chemical
composition of which is such that the initial impact produced modifies in the
required manner the too powerful or too weak effect of the cap or detonator used,
by absorbing, equalizing, or compensating, any fluctuations or irregularities which
may take place on ignition.

Improvements in Cartridges.
1, HERMANN GÜTTLER, of Reichenstein, Silesia, Kingdom of Prussia, German
Empire, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
Priming caps or detonators are usually defective as regards the quality and
uniformity of the detonating compound or priming. It is not practicable to obtain
uniformity in the detonating compound or priming because it is employed in making
the cap or detonator in a moist condition and cannot be exactly weighed and there-
fore the caps or detonators more particularly those employed in sporting rifles
cannet be adjusted with sufficient precision to exercise a uniform action upon the
charge in the cartridge and especially is this the case with certain classes of
smokeless powder which do not readily detonate, such as plastomenite. The conse-
quence is inefficiency, in effect, and it is the object of the present invention to
remedy this. For this purpose the same consists in arranging between the cap or
detonator and the charge an intermediary primer consisting of a predetermined
quantity of a smokeless explosive substance or substances correctly weighed while
dry, and the chemical composition of which is such that the initial impact produced

detonator used, by absorbing, equalizing, or compensating any fluctuations or
irregularities which may take place on ignition.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
In cartridges especially for sporting rifles the combination of a hardly inflammable
smokeless charge and a detonator or priming cap, of an intermediate smokeless
priming arranged between the detonator or priming cap and the smokeless charge,
the said intermediary priming being prepared and composed as and for the purpose
stnted.
