Letters of like name and kind refer to like parts in each of the figures.
The object of my invention has been to provide an improved repeating magazine
pistol, which shall be capable of being most readily and quickly recharged, shall
have a clean, sharp trigger pull for releasing the firing mechanism, and shall be
without any joint between the firing chamber and the barrel through which the
powder gases can escape, to diminish the pressure within the barrel applied to the
propulsion of the projectile, and to this end-
My invention consists in the pistol and the parts thereof, constructed, arranged,
and combined, as hereinafter specified.
While the arm, as it will be shown and described is especially intended for cavalry
use, being so designed and arranged as to admit of the best and steadiest possible
aim, during the pull off for firing, and a quick recharging, with a minimum use of
the bridle arm, it is well adapted for employment elsewhere, wherever a good
shooting repeating pistol is desired. A special purpose which I have had in view,
and which will be found to have been carried out in inventing the present arm, has
been to make certain of having such an easy pull off, as will enable the user to
secure good aim in firing, to have all the movements of the various parts of the
mechanism, except those of the firing pin and sear, positive, and to obtain them
all by a simple rearward pull or pressure of the fingers of the hand gripping the
stock or butt. While the magazine shown is of the detachable kind, known as the
"Burchard Lee," and while I prefer that kind as the most convenient and best, 1.
desire it to be understood that I do not limit myself thereto, but contemplate using,
with the operative mechanism of the pistol, any other desired form of cartridge
holding and feeding device, adapted to feed the cartridges up into position to be

page_text: engaged by the breech bolt and carried forward thereby into the chamber of the
barrel, as in any of the well known forms of bolt gun.
For quick re-charging, the detachable magazine is found the best, but, if desired,
my pistol can be provided with a fixed one, whether occupying the position of the
one shown, or consisting of a longitudinal tube with suitable feed spring follower,
and carrier to lift the cartridges up into the path of the bolt.
In the drawings, A, A, designate the frame, having the receiver A' for holding
the operative parts of the mechanism, the bolt-way A', for holding and guiding
the reciprocating bolt B, the magazine holder, for receiving and holding the
magazine, arranged, so that the bolt will reciprocate over the top of the magazine,
in position to engage the head of the top cartridge and carry the latter forward,
and the barrel A³ screwed or otherwise fastened into the frame in line with the
bolt. As shown, the receiver has a removable side plate A*, to be fastened in place
by screws or other fastening devices, as desired, while, for convenience in assembling
and dismounting the different parts of the mechanism, the several stationary
supporting pivot pins are driven or otherwise fixed in the frame. If preferred,
however, any one or all of the pins may be made removable from the frame, without
involving any departure from my invention.
The main or forward part of the bolt B is, preferably, but not necessarily, made
cylindrical, while its rear portion is, on its under side, provided with the two series
of teeth or racks b, b, arranged so as to leave a longitudinal space between them.
Within this bolt, which is hollow, is arranged the firing pin C, having forward
end reduced in size to pass through the small opening &' in the bolt end, so as to
reach and explode the primer of the cartridge, when the bolt has been thrown
forward.
€3
To the rear of this reduced striking part, the firing pin has the head or collar c
engaged by the spiral spring C₁, whose other end bears against the hollow screw 2
screwed into the bolt and surrounding the shank of the pin. On the outer end of
the latter is the cocking piece or head c', held by the nut c² screwed upon the firing
pin and fixed from turning thereon by the pin passing through it, and into the
head. A horizontal longitudinally extending arm c on this head passes forward
into the space on the underside of the bolt between the two racks b b on the latter,
and has a shoulder e and undercut safety notch co to be engaged by the sear, to be
described, when the pistol is at full cock and half cock, respectively.
To prevent any tendency on the part of the bolt B to turn or twist in its way, a
pin 63 can be provided on the frame, extending into and engaging a longitudinal
groove in the bolt side.
Instead of this arrangement, the bolt and way can, of course, be made non-
cylindrical, or so shaped that turning of the bolt will be impossible. Such a
change from the construction shown would not involve any departure from my
present invention.
The rear portion of the cocking piece or head c¹ is, preferably extended upward
as shown, and, as its motion with the bolt is a rectilinear one, in line with the
barrel, it can be notched or otherwise arranged, so as to be used as a rear sight in
connection with any desired form of front sight.
Pivoted upon pin D, within the forward part of the receiver, is the trigger E,
which, as will be seen, serves to trip the sear, operate the bolt lock and actuate the
bolt throwing mechanism. It has, on the rear side of its body or main portion, a
concentric face e, forming a portion of a cylinder whose axis is coincident with the
trigger pivot, a depression el at the lower end of such face, and teeth e² below the
depression.
On the upper side of its pivotal portion, is a cam, lug, or projection e, which,
when the trigger is forward in its normal position, stands just to the rear of the
end of the fly F on the sear F', so that the first rearward movement of the finger
engaging arm of the trigger, will cause the sear to be swung, to release the firing
pin from its retracted position.
The sear and fly are both pivoted on the pin D', which, as indicated herein before,

page_text: can be a driven or a removable one, and have their pivotal portions provided with
shoulders and f¹, respectively, which allow a limited movement of the two parts
on the pivot independent of each other.
A double armed spring f2, having a loop f³, engaging pin D², so that the
spring cannot turn thereon, has its opposite arms bearing against the sear and
fly, respectively, so 'as to hold them swung apart as far as their shoulders f and f¹
will allow, and to keep the sear pressed upward into position to engage the shoulder c
or the notch on the arm e of firing pin head c¹.
With this construction, the sear will, when the bolt B has been moved rearward
and is travelling forward again to carry the cartridge into the chamber of the barrel,
engage the shoulder and hold the cocking piece or head c', and, consequently, the
firing pin, retracted against the stress of spring C₁.
If the trigger E has been swung rearward and is being returned to its normal
position again, the fly F will yield to let the tripping lug e pass under it, and will
then fly forward into position in front of such lug.
To prevent the turning of spring f2 on pin D2, the latter can be flattened or
made non-cylindrical, to fit a correspondingly shaped space within the spring
loop f³.
Pivoted upon pin D³, to the rear of the trigger F, is a bolt thrower G, having
on its upper portion, the two segmental racks 1, g, to mesh with racks b, b on the
bolt, and the channel g' to leave space for the accommodation of the sear, sear spring
and fly, already described.
On the pivotal portion of this thrower is a forwardly extending locking toe g²,
which, when both trigger E and bolt thrower are forward in their normal positions,
as shown in Figure 4, is adapted to engage the concentric cylindrical face e on the
trigger, so as to hold the thrower from swinging rearward to retract the holt, or
allow the latter to move back.
The face engaging portion of the toe is preferably made concave, as shown, so as
to be concentric with said face, when the thrower is swung forward in its bolt-closing
position.
On the pivotal portion of the thrower, below the toe, are the teeth y³ adapted
to mesh with those on the trigger, when the latter has been swung rearward far.
enough to release the toe from the locking action of the concentric face e on the
trigger.
Said face is made of such extent as to securely hold the bolt thrower from any
backward movement until after the trigger has been swung far enough to cause
its projection to engage the sear Hy F, and trip the sear F', so that a firing
action is secured. The bolt would then be held forward in a closed position during
the firing.
To effectually lock it, without depending upon the bolt thrower alone, I provide
the lock H adapted to engage and be raised out of the locking notch or depression 65
in the upper side of the bolt, and consisting, preferably, of an inverted U-shaped
piece, having the main upper portion or head, for engaging the bolt notch, fitting
and moving in an opening in the upper part of the frame, above and partly
surrounding the bolt-way, and the two legs hh, extending downward on opposite
sides of said way, into the receiver space, and guided in vertical grooves h¹ h', in the
receiver walls.
Where, as described hereinabove and shown in the drawings, one side of the
receiver is formed of a removable cap or plate, the latter can be grooved to receive
one of the lock legs, and have a projection 2 to form a shoulder for the under
side of main part of the lock to rest upon, when down in locking position; see
Figs. 1 and 5.
The lower portion of the lock legs extending down on opposite sides of the bolt
thrower G and trigger E, are provided on their lower ends with pins ³, 13, to engage.
the cam groove in the body or main part of the trigger. Each of such grooves
consists of the forward and rear portions concentric with the trigger, connected by
an incline or eccentric part. Of these concentric portions, the forward one is nearer

page_text: .
the center of movement of the trigger than the other is, being so arranged as to
hold the bolt lock down in locking position. It is also made of such length that
the lock will be held, as described, until after the trigger has been moved to secure
a tripping of the sear and firing of the pistol. Continued movement of the trigger
then brings the upward and rearward incline e' of each groove into contact with its
respective pin 3, so that the lock is raised to unlock the bolt. After such raising,
as the pins on the lock legs are in the outer concentric portions of the grooves,
the lock will be held, as raised, and the trigger will be free to be moved further,
to cause the movements of the bolt thrower herein before indicated and more fully
set forth hereinafter.
For convenience sake, especially where, as I prefer, the various pivot pins are
driven ones, one leg of the bolt lock, the outer one, is hinged to the lock body, as
by a pin passing through two ears h³ on such body, and a projection or ear h
on the leg.
I do not, however, limit myself to such construction, but can, instead, detachably
attach or hinge the leg to the lock body in any other desired way, without departure
from my invention.
Where it is desirable, the lock legs can both be made integral with the body, if
the pivot pins of the trigger and bolt thrower are made removable and not fixed or
driven.
With the parts constructed as already described, and occupying the positions
shown in Figure 4, a rearward pull on the trigger E would cause first a tripping of
the sear to release the firing pin for firing the cartridge in the barrel chamber, then
a lifting of the bolt lock to release the bolt, and then, through the engagement of the
upper side of the first tooth of the teeth e² on the trigger with the toe g² and the
subsequent meshing of teeth e³, e2 with the thrower teeth g³ g³, a rearward swinging
of the thrower to quickly retract the bolt.
If desired, a spring, put under compression by the described movements of the
trigger and thrower, could be used to return them to their first normal positions
again, the bolt, on its forward travel, being caused, in the usual well known way,
to carry a fresh cartridge from the magazine into the chamber of the barrel; but I
prefer to make the operation of the pistol positive, and not to depend upon a spring,
in the manner and for the purpose indicated.
I therefore provide a rear trigger I, in addition to the one described, preferably,
but not necessarily, pivoted upon the same pin D³ with the bolt thrower G.
As shown, its pivotal portion is in the form of a nose entering a recess or slot in
the pivotal part of the thrower, but I do not intend to limit myself to such construction.
In general form, it is very nearly a right angled lever. At or near its angle is a
pin i, whose opposite ends, projecting beyond the sides of the trigger, engage openings
in the rear ends of the two links K, K, which, extending forward ou opposite sides
of the receiver space, are pivoted upon pin D³, and have in their forward ends short,
longitudinal slots kk, engaging the pin k passed through the rear portion of the body
. or main part of trigger E.
Instead of using the pins i and k³ passing through the rear and forward triggers,
respectively, as described, I can, of course, employ link engaging studs or short pins
made integral with or inserted in the respective triggers, without involving any
departure from my invention.
With the construction described, a rearward movement of the forward trigger to
fire the arm, unlock the bolt, and retract the latter, in the manner set forth herein-
before, will, through the action of the two links, cause the rear trigger to be swung
forward into the position indicated by dotted lines in Figure 4, and a rearward
pull on such trigger will throw the other trigger E forward again to its normal
position, causing the bolt thrower to close the bolt and hold it closed, and the bolt
lock to descend into its locking position again, through the operation of the cam
grooves on the trigger upon the pins of the lock legs.
To enable the front trigger E to be moved rearward far enough to trip the sear
and secure a firing without movement of the rear trigger, I, preferably, enlarge or

page_text: slot the pivot holes k²² of the links K, as shown best in Figure 6. The pistol can
then be fired without a releasing of the grip upon the rear trigger, and, conse-
quently, without any interference with a firm hold or grip upon the pistol butt or
stock.
Obviously, one link might be employed to connect and operate the two triggers the
one from the other, without departure from my invention, but I prefer the two, as,
by them, I avoid all chance of any twisting action, which is especially to be avoided
in pistols.
To secure a retraction of the firing pin within the bolt, when the latter is first
moved rearward and while it is to the rear of its closed position, I provide the bolt
with the bell crank lever L, which, being pivoted in a slot in the former, has the
inner armadapted to engage the forward side of the collar.c on the firing pin, and
the outer arm arranged to project beyond the bolt periphery when the inner arm
is swung into position to leave the firing pin free to be thrown forward to the full
extent of its movement.
A recess in the wall of the bolt way serves to allow the outer arm of the
retractor to project, as described, when the bolt has been fully closed.
During the first rearward movement of the bolt from said position, the inclined
bottom of the recess cams the outer projecting lever arm inward, so as to swing
the inner arm back in the bolt, to retract the firing pin, as will be understood from
Figure 12 of the drawings. The wall of the bolt-way will then hold the retractor
as moved until the bolt reaches its closed position again.
The cartridge shell extractor M, can be of any one of the well known forms, and
need not be described herein.
The opening N, for allowing the ejection of the shells, is, preferably, placed as
shown, on the left side of the bolt-way, but can, instead, be arranged on the other
side, or on the top of the frame, as desired, the position of the extractor being
changed accordingly.
The magazine O shown, is, as indicated hereinbefore, of the kind commonly
known as the Burchard-Lee, and need not, therefore, be described in detail herein.
The holder for detachably holding it with its top in proper position with reference
to the bolt-way, consists essentially, of an opening or slot in the under side of the
forward part of the frame, in front of the trigger guard, adapted to fit the upper
part of the magazine, and having in its rear side, which is continued downward
nearly to the full depth of the magazine, a vertical groove o to receive the rib o' on
the magazine case. On such rib is a notch o² to be engaged by the nose of the
latch P normally held projected in operative position by a spring p. The construc-
tion of this latch is best shown in Figures 4 and 14. It consists of a pin inserted
and moving in a cavity pl in the frame, and having its inner end engaged by the
spring preferred to above. Its nose is made with the inclined under face to
facilitate the quick thrusting of the magazine up into place, and in its left side is a
notch p² with its inner end inclining outward to form a cam p³. Guided in
a passage at right angles to the cavity p' is a latch operating push piece or pin p
whose inner end, projecting into the notch p² is adapted to engage cam p³ so as to
force the latch inward against the stress of its spring p when the pin is pressed in.
A small screw projecting into a cavity p' in the side of pin p serves to keep
the latter from falling out, while leaving it free to be pressed inward to trip the
Jatch.
The operation and manner of using my pistol are briefly as follows:-
With the pistol loaded and the parts in position shown in Figure 4, an easy pull
on the forward trigger will cause a tripping of the sear to release the firing pin
before the said trigger is made use of to cause movement of any other of the
operative parts of the mechanism.
The pull off is then, a clear, clean one, such as cannot be secured in any of the
so-called double action pistols heretofore made, in which the trigger only trips the
sear after it has been moved rearward so as to cock or make the pistol ready for
firing.

page_text: After the cartridge has been fired, a continued movement of the forward trigger
unlocks the bolt, by raising the bolt lock through the engagement of the inclined
parts of the grooves in the trigger body with the pins on the lock legs. The
cylindrical concentric face on the trigger then passes by the toe on the bolt thrower
so that the lower corner thereof is free to swing into the depression e¹ and the
mpper side of the first tooth e², striking such corner, starts the thrower back to
retract the bolt. The meshing teeth on trigger and thrower then quickly complete
the bolt opening motion of the latter.
Meanwhile, the retractor has retracted the firing pin in the manner indicated
and the extractor has extracted the fired shell from the cartridge chamber in the
barrel and caused it to pass outward through the opening in the frame.
The rearward motion of the forward trigger has, through the links described,
carried the rear trigger to the front. The latter trigger is now pulled rearward to
return the forward trigger to its first position with a consequent swinging of the
thrower to close the bolt and carry the cartridge from the magazine into the barrel
chamber, and lowering of the bolt lock to lock the bolt again.
As the forward trigger reaches its normal position, its firing lug or projection
passes under the sear fly, which yields to it and then snaps into place in front of it,
ready for another firing movement.
When the magazine becomes empty, it can be easily and quickly detached, if.
the latch operating pin is pressed inward, and a fresh magazine thrust into the
holder.
When the pistol is used by a cavalryman, it can be readily recharged with the
minimum use of the bridle hand. The barrel having been dropped into such hand,
without a releasing of the reins, the fore-finger of the right hand, used to detach the
empty magazine case, naturally comes upon the latch of tripping pin. Pressure on
the latter causes the magazine case to be released so that it can be quickly removed
to make way for a filled one, which, when in place, will be caught and held by the
latch.
In order that the user of the pistol may be notified at once, when a magazine has
been emptied, I contemplate turning up the rear end of the magazine follower R, so
as to form a lip v, which, after the last cartridge has been removed, will project
upward above the magazine top, into the path of the forward end of the bolt, so as
to stop the latter, when it has been retracted.
From the description given hereinbefore, and the drawings, it will be seen that
I have, by my invention, provided a simple, compact, repeating pistol, which can be
used and operated by one hand, and in which all the movements of the various parts
are secured by a simple, strong and rearward pull of the fingers of the bolt gripping
hand.
It will also be seen, that in the preferred form of my pistol with the two triggers
.connected in the manner described, I am enabled to make all the movements of the
parts, except the sear device and firing pin, positive, while, with the firing
mechanism arranged to be actuated before any of the other parts are moved, I
secure the easiest and clearest possible pull off, which is necessary, in order that
good aim may be had and maintained during firing.
