COMBINED PULL AND RELEASE TRIGGER
Poyner J. Jones, Cristobal, Panama Canal Zone
Application October 20, 1937, Serial No. 170,091
. 14 Claims. , (Cl. 42-69)
My invention relates to new and useful-im
provements in a trigger mechanism for a shot
automatically cocks the trigger, making the gun
ready to be again re?red.
gun, and more particularly to a mechanism which
Still another object of the invention is to pro
vide a trigger mechanism that may be quickly
and easily applied to automatic or pump guns
with but very little trouble,.and after once ap
plied, the gun may be used as an ordinary pull
may aptly be called a “pull or release trigger”.
As is well known to those skilled in the art,
within recent years there have been a number of
trigger mechanisms wherein the gun is ?red by
releasing the trigger rather than by pulling the
trigger. This trigger mechanism is known as a
10 release trigger. The real purpose of the release
trigger is to try to overcome the tendency in the
shooter to “?inch”, which ?inching is due to
nerves and also to the fact that in applying pres
sure to the trigger, anywheres from three and
15 one-half to seven pounds, the muscles become
taut and the shooter is unable to hold the gun
at the desired point of position or even pull the
trigger.
It is a well-known fact, however, that where
20 a release trigger is used, the loosening of the
muscles, that is, on the releasing of the trigger,
has a great tendency to overcome ?inching.
Release triggers have heretofore been mostly
applied to trap guns, that is, guns which are
25 used at the traps, rather than to ?eld guns, as
to change over entailed a dismantling of the
mechanism.
.
~
An object of my invention, therefore, is to pro
vide an exceedingly simple trigger mechanism
30 that may be applied to a shotgun and, if desired
to shoot over the traps, by simply pressing a small
detent, the trigger mechanism may be trans
formed from a pull trigger actuating mechanism
to a release trigger mechanism.
A further object of my invention is to provide
35
a trigger mechanism that may be quickly ap
plied to a shotgun of the “pump” type, that is,
where the fore end is actuated to eject the old
shell, force a new one in position, and cock the
40
gun.
,
The shooter may press the detent so that when
shooting at doubles, he may press the small
detent or, in other words, set the gun for the
release trigger on the ?rst bird of the pair, ‘and
45 when the fore end is shifted, the second bird may
be shot with the trigger mechanism arranged
for the pull trigger. In other words, every time
the run is cooked, the trigger will be of the pull
type or of the ordinary type but may be changed
50 over instantly by pressing the small detent, which
will be later described.
Also, the trigger mechanism may be equally
as well applied to what is known as the “auto
matic” shotgun, that is, where the recoil ejects
55 the old shell, places a new one in position, and
trigger gun or press a small detent and make the
trigger of the release type.
Still another object of the invention is to pro
10
vide a trigger mechanism that consists of sub
stantially two additional sears which may be
quickly added to, say, the Winchester pump or
automatic gun, it only being necessary to make
a few mechanical changes.
15
Still another object of the invention is to pro
vide a trigger mechanism wherein the trigger is
ordinarily arranged for the pull type but may be
quickly changed to the release type, or if the
shooter changes his mind, by pressing another 20
detent, the trigger mechanism is again set for
the pull type trigger.
With these and other objects in view, the in
vention consists in certain new and novel fea
tures and combination of parts, as will be here
25.
inafter more fully explained and pointed out
in the claims.
Referring now to the drawings which show a
trigger mechanism stripped of the parts that
are not necessary for an understanding of the 80
invention,

sear which cooperates with the aforementioned
sear.
.
.
At the outset, it might be mentioned that the
actuating mechanism for the hammer, that is, to
cock it, and the safety catches and a few other
‘parts have been omitted, so that the present in
vention may be more clearly understood.
In Fig. 1, there is shown the frame I with the
trigger guard 2, the conventional hammer 3, its
10 spring 4, the trigger 5 with its combined sear 5,
which fits within the sear notch ‘I formed in the
under portion of the hammer 3. The combined
scar and trigger 5 is pivoted, as at 8, while the
small spring 9 is compressed when the trigger
15 5 is pulled and which, in turn, will force the
sear 8 in an upward position and the trigger 5
pulled from the sear notch ‘I and the spring 4
will force the hammer .to strike a ?ring pin (not
shown) to thus ?re the gun. The sears II and I1
and likewise the hammer 3 will be in the posi
tion clearly shown in Fig. 2. It wil be noticed that
the sear I1 is still in engagement with the arm ll
of the sear II.
Transformed to release trigger
Now when it is desired to have the mechanism 10
act as a release trigger type, the gun will again
be cooked by forcing the hammer 3 rearwardly in
the ordinary manner to the position as shown in
Fig. 3 and the arm Not the sear II will be mo
mentarily pushed upwardly to throw the arm I8
slightly rearwardly until the nose I9 becomes dis
engaged from the arm I4 to assume the position
back to its normal position after the trigger 5
has been pulled and the hammer released.

To add this additional mechanism especially
to a Winchester typegun, it has only been neces
sary to mill out the inner frame widely enough to
permit the insertion of the two additional sears
55 II and I1 and to drill the trigger for the pin at
I5 and the pin at I0, after which the two sears
may be inserted, Also, of course, the additional
stud 23 will have to be added to the hammer.
After this has once been done, the mechanism may
60
be utilized as a pull trigger, or by simply pressing
the detent 20, the action will be that of the release
type.

DESCRIPTION AS To run OPERATION

Pull trigger
Now supposing that the hammer has been
cocked by conventional means (not shown), the
sear 5 will have. engaged the sear notch ‘I in the
hammer and all of the parts will be in the posi7
tion shown in Fig. 1, the nose I9 of the second
supplemental sear I‘! being over the arm. ll of
the ?rst supplemental sear II, but the nose I3
of the arm I2 of the sear II will not be in en
gagement with the projection or stud 23. Thus,
when the trigger 5 is pulled, the sear 6 will be
position being clearly shown in Fig. 4 as dis
tinguished from that shown in Fig. 3_. As the
trigger 5 is now released, the sear 6 will move
upwardly, due to the spring 9, it being remembered 50
that it is pivoted, as at 8, and the trigger will
move forwardly and slightly downwardly, and
the sear II, through the arm I4 being in engage
ment withthe arm I8 of the sear II, which is
pivoted to the trigger 5, as at I6, will rock slightly
rearwardly (it being locked to the trigger by the
sear I‘I.) until the nose I3 of the arm I2 becomes
disengaged from the projection or stud 23, which
will release the hammer 3 to strike the ?ring pin 60
(not shown) and ?re the gun“
When the gun' is again cocked, the position
of the parts will be returned to that shown in
Fig. 1, and unless the forward end 20 of the sear
I1 is pressed upwardly, the gun will be of the
ordinary pull trigger type.
At the moment, however, that the arm 28 is
again pushed upwardly, it will become a release
trigger mechanism, as just explained.
It will be noticed that the arm (detent) I5 of 70
the sear II also extends below the trigger, so
that should the shooter, having decided to throw
in the release type mechanism by pushing up
the arm 20, change his mind, by simply pressing
up on the exposed end of the arm I5, the parts 75

For shooting doubles, that is, where two clay
birds are thrown from the one trap at the same
time, if the mechanism is used, say, on an auto
matic gun, the mechanism may be set for release
type, so that when ?ring at the first bird, it is
25 only necessary to release the trigger.
On the
second bird, the trigger will be operated as the
pull type, so that the shooter does not have to
press up on the detent 20 during the ?ight of the
birds, because when the gun is recocked for ?r
30 ing, it will be remembered that the mechanism
will now be set for the pull trigger type.
It will be understood that the addition of these
parts to an ordinary type of gun entails but little
work and, of course, the mechanism may be

raised to cause the arm on the second-mentioned
sear to engage the stud on said hammer and to
throw the third-mentioned sear out of engage

it will be seen that it is but the matter of a

operation, or after having once changed it, it is
but the matter of a moment to change it back to
