PROVISIONAL SPECIFICATION.
A New or Improved Device for Lessening the Report of Firearms.
I, JAKOB STAHEL, of Wollishofen, near Zurich, Switzerland, Cartridge
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved device to be applied to heavy
sporting rifles and other fire-arms, in order to reduce or prevent the noise of the
explosion.
I make the barrel of the rifle or other firearm in the usual form, but upon its
extreme outer end I fix a hollow socket or chamber of considerably larger diameter,
closed at its outer end with the exception of a central hole of sufficient size to allow
the projectile to pass through it. The chamber thus formed receives the gases
from the explosion of the cartridge, and reduces very considerably the noise of the
report.

COMPLETE SPECIFICATION.
A New or Improved Device for Lessening the Report of Firearms.
I, JAKOB STAHEL, of Wollishofen, near Zurich, Switzerland, Cartridge
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 and accompanying drawing, that is to say :--
My invention relates to a new or improved device to be applied to fire-arms, in
order to reduce or prevent the noise of the explosion.
It is applicable to heavy sporting rifles, or to firearms used for other purposes, as
for instance for the purpose of slaughtering cattle.
The accompanying drawing which is in illustration only of the invention, shews
it applied to the last named purpose, Figure 1 shewing a side view and Figure 2 a
longitudinal section of the improved device. It consists of a percussion device,
combined with a rifled barrel and the sound deadening device. The percussion
device consists of a metal socket a screwed upon the end of the barrel d, a
percussion pin or striker b, and a spring c. To introduce a cartridge the socket a
is unscrewed, and replaced after the cartridge has been introduced into the barrel.
The sound deadener e into which the outer end of the barrel is screwed, is formed
of a small metal chamber e of which the outer end e¹ is provided with a hole
corresponding in diameter with the bullet, and situated exactly opposite to the end
of the barrel, the sound of the discharge being in this way so deadened that it is
scarcely heard. Where used for the purpose shewn the apparatus is attached to
the head of the beast by the upper strap f, with or without a second lower similar
one. When used for other purposes the outer end e' of the chamber may be
parallel with and of the same size as the inner one.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use upon the barrel of a fire-arm of a metal chamber e pierced in its

page_text: front end with a hole to allow the passage of the projectile, and deadening the
sound of the discharge by receiving the gases resulting from the explosion.
Dated this 9th day of August 1893.
