AN IMPROVED GUNLOCK
Year: 1885

page_text: We WILLIAM CHARLES MENTEE trading as John Reeves & Co, Gunmakers and
JOHN HUGHES, foreman, both of 75 Newhall Street Birmingham in the County of
Warwick do hereby declare the nature of the said invention for "AN IMPROVED
GUNLOCK" to be as follows:-
Our Invention relates to an improved lock for hammerless breech-loading guns
and has for its object to reduce the cost and simplify the construction by reducing
the number of parts of the lock to the minimum. According to our invention the
internal mechanism of the lock consists of three parts only, namely the hammer,
the main spring, and sear, all carried by the lock plate.
The hammer and tumbler are combined in one, and the main spring which may
bave either a single or a double limb engages directly with a notch in the tumbler
which has one or two bents corresponding to half or full cock. The lower limb of
the main spring in the case of a two armed spring presses upon the sear behind
its centre or in the case of a single armed spring, a small spiral spring is interposed
between the rear end of the sear and the fixed end of the main spring to force the
sear to engage with the bents of the tumbler.

page_text: We WILLIAM CHARLES MENTEE (trading as John Reeves and Company Gun-
makers) and JOHN HUGHES (Foreman) both of 80 Bath Street Birmingham in the
County of Warwick 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:—
Our Invention relates to an improved lock for hammerless breech loading guns,
and the Invention has for its object to reduce the cost and simplify the construction
of the lock by reducing the number of parts to the smallest possible number.
According to our Invention the internal mechanism of the lock consists of three
parts only namely the hammer, the main-spring, and sear all carried by the lock
plate.
Reference is to be had to the accompanying drawing which represents an internal
face view of the lock plate and parts of the lock mounted thereon.
The hammer a and tumbler b are combined in one as shown. The main spring
cc engages by the end of its upper limb c directly with a notch d in the tumbler
and bears by its lower limb c¹ upon the sear ƒ behind its centre. The hammer and
tumbler turn upon a stud h and the sear upon a stud i both studs being screwed
into the lock plate k to which the main spring is connected by a stud at its bend
received in a hole in the lock plate. The tumbler has a single bent m corresponding
to the cocked position of the hammer, or it may have two bents corresponding
respectively to half and full cock. The tumbler also has a forwardly projecting
toen for engagement with a lifter o on which the barrels of the gun press, as usual
for cocking the hammer, for the purpose of making the gun self cocking as usual.
The main spring shown has two limbs or arms but it may have only one in which
case a small spiral spring is interposed between the rear end of the sear f and the
fixed end of the main spring to force the sear to engage with the bents of the
tumbler, as shown in Figure 2.
Having now particularly described' and ascertained the nature of the said
Invention and in what manner the same is to be performed we declare that what
we claim is;-
1. In a hammerless gun lock the combination of the two armed main spring
directly with the combined hammer and tumbler and with the sear, substantially
as herein specified and represented in Figure 1 of the drawings.
2. In a hammerless gun lock the combination of the main spring, spiral sear
spring, combined hammer and tumbler and sear substantially as specified and
illustrated in Figure 2 of the drawings.
