IMPROVEMENTS IN PRM TRADING CUNG AND DISMAT
Year: 1875

page_text: LETTERS PATENT to William Tranter, of Birmingham, in the County
.of Warwick, Gun Maker, for the Invention of “IMPROVEMENTS IN
PRM TRADING CUNG AND DISMAT "
Sealed the 30th November 1875, and dated the 10th September 1875.
PROVISIONAL SPECIFICATION left by the said William Tranter at the
Office of the Commissioners of Patents, with his Petition, on the
10th September 1875.
.I, WILLIAM TRANTER, of Birmingham, in the County of Warwick,
Gun Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BREECH-LOADING GUNS AND PISTOLS," to be as follows:-
66
My Invention has for its object in the first place the construction of
the lock in such a manner as to combine safety with the facilities of the
'snap action." For this purpose the sliding bolt is blocked in position
by the breast or front part of the hammer or tumbler, so that it cannot
bo withdrawn until the hammer is raised to half-cock. By this arrange-
ment the hammer is preventod from falling on to the striking pin to

page_text: discharge the arm until the sliding bolt is in its proper place for
firing.
My Invention consists in the second place in giving to the cartridge
extractor a double movement, one part of which is effected on the
opening of the arm by causing the empty case to be partly withdrawn,
and the other by afterwards withdrawing the same by means of the
thumb and finger to the required distance to admit of its falling away
from the barrel.
My Invention consists in the third place in forming the slots in the
body or frame of the arm, in such a manner that the lock and lever
(which is adapted for being used by the thumb) and the sliding bolt can
be fitted with facility, and the guard formed in one piece to close the
bottom part of the slot in the body, and to form a proper attachment
for the stock. By this arrangement the manufacture of the arm by
machinery would be facilitated.
And my Invention refers in the last place to a gun or pistol with a
sliding bolt or block moving perpendicularly or nearly so, and with the
sliding block actuated by a lever placed on the side or bottom of the
arm. This sliding block is intended to be locked or blocked in its
position for firing by the front part of the hammer or tumbler in a
similar manner to that stated in the first part of my Invention.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing dato the. Tenth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me; the said William Tranter, Her special
licence that I, the said William Tranter, my exécutors, administrators,
and assigns, or such others as I, the said William Tranter, my executors,

page_text: administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, excrcise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN BREECH-LOADING Guns and PISTOLS," upon the condition (amongst others)
that I, the said William Tranter, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Tranter, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawings hereunto'
annexed, and to the letters and figures marked thereon (that is to
say) :—
My Invention of "Improvements in Breech-loading Guns and
Pistols," has for its object in the first place the construction of the lock
in such a manner as to combine safety with the facilities of the " snap
action." For this purpose the sliding bolt is blocked in position by the
breast or front part of the hammer or tumbler, so that it cannot be
withdrawn until the hammer is raised to half-cock. By this arrange-
ment the hammer is prevented from falling on to the striking pin to
discharge the arm until the sliding bolt is in its proper place for firing..
My Invention consists in the second place in giving to the cartridge
extractor a double movement, one part of which is effected on the
opening of the arm by causing the empty case to be partly withdrawn,
and the other by afterwards withdrawing the same by means of the
thumb and finger to the required distance to admit of its falling away.
from the barrel.
My Invention consists in the third place in forming the slots in the.
body or frame of the arm, in such a manner. that the lock and lever,
(which is adapted for being used by the thumb) and the sliding bolt can.
be fitted with facility, and the guard' formed in one piece to close the

page_text: by the guard or bottom strap, and at the top by means of a top strap or
plate.
By the means described the lock and lever arrangement is made to
work with freedom, and is fitted with facility, and the slots are formed
[readily by machinery.
The Invention as above described is applicable to double or single
guns or rifles, to pistols with two barrels placed one over the other with
a movable striker, or with two barrels in a horizontal position, or to.
pistols with four barrels and with a revolving striker.
The Invention as above described may be so modified as to fix during
the firing a sliding bolt or block moving perpendicularly or in a slanting
direction by means of the front part of the hammer, or a tumbler or
bolt acting therewith.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I claim
as of my Invention is,―
First. The fixing of the sliding bolt during the time of firing by
means of the hammer or a tumbler in the manner described.
Secondly. The cartridge extractor with a double movement as herein-
before described.
Thirdly. The formation of the slots in the manner described and the
general construction of the arm arising therefrom..
And, Lastly. The adaptation and application of the locking principle
described to guns or pistols with a perpendicular or slanting sliding bolt
or block.
In witness whereof, I, the said William Tranter, have hereunto set
my hand and seal, the Tenth day of March, in the year of our
Lord One thousand eight hundred and seventy-six.

WILLIAM SPENCE,
