COMPLETE SPECIFICATION.
Improvements in Breech Loading Small Arms.
I, ROBERT DINSMORE, a citizen of the United States, residing at Passaic,
County of l'assaic, State of New Jersey, United States of America, Mechanic, 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 follow-
ing statement:―
The object of my invention is to produce improvements in fire arms, par-
ticularly of the magazine repeating type, whereby the means and method of
operation are materially simplified, the number of operative parts is reduced.
the strength and durability of the gun is increased, the facility and accuracy of
performance of its several functions are perfectly insured, and rapidity, coupled
with absolute safety from accident in firing under all conditions, is secured.
Positive means for ejecting empty shells is provided by my present invention,
as well as means for re-loading without the aid of the magazine, but those are
but instances of numerous details which are comprehended within the scope
of my invention, and which, having been described in detail in the Specification,
will be succinctly pointed out in the appended claims.

Referring to the figures on the drawings:
1 indicates that portion of my gun which I shall call the frame, consisting,
as it does preferably of a single metallic casing, to which at its forward end is
secured, as usual, as by screw threads 2 (see for example Fig. IV) a barrel 3, and
at its rearward end, as by extensions 4 and 5, for example, the stock 6. The
stock is preferably, but not necessarily, composed of two halves 7 and 8, the
plane of division being clearly shown in Fig. III by the line 9. The two halves
of the stock may be united, as by transverse screws 10, and are finished by a butt
plate 11 that may be provided with the ordinary feed aperture 12 that may be
opened and closed by means of a sliding shutter 13.
To provide for firmly and rigidly uniting the two-part stock to the frame, I
secure to one of the parts, as for example the part 7, just below the grip 14, op-
posite angle-plates 15 and 16, respectively. Each of the angle plates is secured,
as stated, to one part of the stock, as by screws 17 and 18, respectively, and the

page_text: plates are in turn firmly fastened to the extension pieces 4 and 5, respectively,
as by machine screws 19 and 20. By this means a rigid union between the one
half of the stock and the frame is effected, in consequence whereof when the
other side of the stock is united to it by the screws 10, the two parts constitute
a rigid and compact whole.
The stock may be made in the manner previously described, or in any other
suitable manner, as for example, upon a skúleton frame extension 21, as shown in
Fig. XXIX, the object being to secure means for providing within the stock a
magazine chamber and mechanism for feeding cartridges from the magazine
chamber to the cartridge chamber in the breech of the barrel, as required.
In order to provide the magazine chamber within that form of embodiment of
stock shown in the figures, except Fig. XXIX, et sec., I provide in each of the
pieces 7 and 8 recesses 22 and 23, respectively. The recesses should be of suitable
altitude and length to accommodate a predetermined number of cartridges and,
when united, should be of sufficient width collectively to receive a cartridge of
the required caliber between them. Each of the recesses is preferably provided
with a transverse groove 25, whose forward edge is preferably defined by a
metallic strip 26 secured in place, as by screws 27. The oppositely located
grooves 25 are designed in practice to retain and loosely guide the heels of the
cartridges contained within the magazine chamber.
་
Within one of the recesses, which when united constitute the magazine
chamber, as for example, the recess 23, I provide an arm 28, whose bent end 29
is adapted to travel within the segmental groove 30, it being yieldingly urged
towards the bottom or discharge end of the magazine chamber, as by a coiled
spring 31, which may be made integral with the arm. The end of the arm be-
yond the spring may be inserted into the material of the stock, as shown in
Figures IV and V. The office of the spring-actuated arm 28 is to keep the car-
tridges collectively urged towards the discharge end of the magazine chamber,
and to prevent them from rattling while in place within the same.
Guns of the type to which my invention belongs require means for feeding car-
tridges one by one from the magazine chamber to the cartridge chamber 32 in
the breech of the barrel. The means which I employ consists preferably of a
flexible feed slide, which consists of a forward section 35, an intermediate section
or link 38 pivoted to the section 35, as indicated at 39, and a terminal or cartridge
carrier section 40. The link 38 is preferably provided with a knuckle 41, that
fits between a pair of lugs 42 secured to the under side of the carrier section of
the feed slide, near its forward end, as by means of a pintle 43.
The details of the forward sections of the flexible feed slide are clearly illus-
trated in Fig. XIII of the drawings, and those of the carrier section thereof are,
in like mannor illustrated in Fig. XII.
The carrier section of the feed slide moves within opposite parallel grooves 45,
provided for it in the parts 7 and 8 of the feed stock. Those grooves may be
clearly seen by comparing for example Figures IV and VI of the drawings. The
forward portions 35 and 38 work within opposite grooves 46 defined in the side
wall of the frame 1 and in a rib 47 on the interior side of the lower wall of the
frame 1. These grooves, as may be clearly understood by reference to
Figures XVIII to XXIV of the drawings, extend the entire length of the frame,
and align at the forward end thereof with corresponding grooves 48 in the front
extension of the stock.
Below the portion 35 of the feed slide in the lower wall of the front exten-
sion 49 of the stock is provided a narrow, oblong aperture 50 through which, as
by means of screws 51, a hand grip 52 is operatively secured to the part 35, that
part being provided with a thickened rib 53 to lend rigidity to it at its forward
end. By means of the hand grip 52 the feed slide, throughout its entire length,
may be reciprocated by operating the hand grip in the usual manner.
Although it is one of the objects of the feed mechanism to advance the cart-
ridges from the magazine chamber to the breech chamber 32, yet in my gun, it

page_text: is so intimately connected with the mechanism which adjusts and delivers the
last cartridge of the series into the breech chamber preparatory to firing, and
to the firing mechanism, that I deem it conducive to clearness to proceed, after briefly
referring to the course pursued by the cartridges from the magazine chamber to the
breech chamber, to describe the mechanism which actuates the last cartridge of
the series, reserving to a later portion of the specification the detail description
of the mechanism by which the cartridges are conducted one by one from the
magazine chamber to the breech chamber.
Proceeding accordingly, therefore, reference may be had especially to
Figures XV, XVI and XVII of the drawings, in which the preferred course
pursued by the series of cartridges from the magazine chamber to the breech
chamber is illustrated.
I prefer to provide for the purpose specified within the stock and the frame a
clearly defined passage through which the cartridges are impelled with a step
by step movement. The passage is more or less of skeleton form within the stock,
being defined by a partially cylindrical plate 55 in the part 8 of the stock, which
is more accurately defined at its forward end by a partially cylindrical deflecting
plate 56. The form of the deflecting plate 56 may be clearly understood by com-
parison of Figures IV and VII, inclusive, with Fig. XVI of the drawing. It
is also illustrated in Figures XV and XVII, and in the latter figure its office
as a deflecting plate may perhaps be more clearly apprehended; that office being
to guide the series of cartridges to a deflected channel 58 in the frame 1 that
constitutes the forward portion of the cartridge passage.
As will hereinafter appear, each cartridge as it advances from the magazine
chamber to the breech chamber, is successively operated upon by separate and, in a
measure, independent groups of mechanisms, and for that reason I deem it expedient
to assign to each of the cartridges shown in Figures XV and XVII, a separate
reference letter, it being understood that a reference letter, as contradistinguished
from a numeral, wherever found, indicates a cartridge, and that a particular letter
will indicate the position in the series, as completely illustrated in Figures XV
and XVII.
Accordingly, A indicates the breech chamber cartridge, or that one completely
introduced into the breech chamber; B the next one in the series; C the next;
D the next; E the next; F the last of the series within the passage (see Fig. V)
and X any of the number outside of the passage, or in the line of direct advance-
ment, but confined within the magazine chamber (see Figs. IV and VI).
The gun frame 1 is essentially a hollow or chambered piece, fashioned to ac-
commodate the internal mechanism of the gun, and is provided on one side with
a removable side plate 60 (see Fig. 1), which being secured in place, as by screws (1,
constitutes a removable wall for the side of the frame opposite the channel 58,
the frame being otherwise, as previously specified, of one piece.
The side plate 60 completely closes the side of the frame upon which it is
located, with the exception of a cartridge ejecting aperture 62, which, communi-
cating with the interior of the frame is of such dimensions as to permit the ejection
through it of a cartridge or cartridge shell, as required.
Referring in the first place particularly to Figures IV VI and XVIII, in which
the parts about to be referred to are shown in the position ready for firing.
63 indicates a breech block (illustrated in detail detached in Fig. 1X) to which,
as upon a depending lug 64, as by means of a pintle 65, is pivoted the sides of the
bifurcated, forwardly projecting end 66 of a locking block 68.
The breech block is provided upon one side, next to the channel 58, with a
projection 69 (see Figures VI and VII) which, working within a groove 70, in
the side wall of the frame, (see Figures V and XXI to XXIV for example), serves,
when the breach block is confined in place by the side plate 60, to guide the
breech block in its reciprocation in direct axial alignment with the barrel 3.
The breech block derives reciprocating movement from the movement of the
locking block, which is, in turn, actuated by the movement of the
'feed slide, being secured thereto as by a link 71, that is pivoted at one end, as

page_text: indicated at 72, within a recess 73, to the locking block, and at the other end,
as indicated at 74, to a knuckle 75, projecting from the upper face of the feed
slide 35.
The locking block and breech block are designed and constructed so as to
completely fill, when in place, the space between the breech end of the barrel 3
and the end of the frame 1 defined by a preferably oblique wall 76.
The frame 1, which embodies the abutment wall 76, is constructed solidly and
of comparatively heavy material, in order through the interposition of the breech
and locking blocks between it and the cartridge, to insure safety in the employ-
ment of the cartridges containing the most powerful explosives.
With the same object in view, the relationships between the link 71, and the
locking block and feed slide, respectively, are so arranged as to cause the link,
when the locking block is in place in firing, to occupy the substantially vertical
and immovable position illustrated in Fig. XVIII, so that this connection
between the cartridge feed mechanism and the locking block serves to lock or
hold the latter firmly in place. The construction of these parts is also such that
when the breech and locking blocks are moved back, the locking block and link 71
fold down close to the cartridge feed devices, thus permitting the parts to be
mounted and operated in a small space.
In this connection, by reference to the figure last mentioned, it may be noted
that the link 71 has an extensive curved head, or upper part 80, which fits snugly
into a corresponding socket in the locking block, and also a shoulder 81 resting
against the locking block, and that its lower end 82 (see Figure VIII) extends
through recesses 83 (see Fig. XIII) in the feed slide. By this means, the full
strength of the link 71, which is made thick and heavy, is interposed directly
between the locking block and the lower wall of the frame 1, and depends upon the
pintles 72 and 74, respectively, solely for guidance during the operation of the
parts, and not for support in forcing the locking block into its position between
the breech block and the abutment wall 76.
It is by means of the mechanism described that I secure the cartridge in the
breech chamber by a rigid mass of metal incorporated substantially with the
body of the frame itself."
It will be observed that the breech and locking blocks when moved back from
the barrel, traved in a plane,-which is, in the form of the invention shown, a
vertical plane cutting through the barrel longitudinally, that is substantially
at right angles to the plane in which the deflected portion of the cartridge passage
is situated, and which, as shown, is a horizontal plane cutting longitudinally
through the barrel. This construction permits the cartridges to be delivered from
the stock to the barrel in that type of gun in which there is a breech and a locking
block reciprocating within the gun frame.
The breech block 63 (see Fig. IX) is provided with a firing pin 85, actuated by
a coiled spring 86 (see Fig. XVIII). The firing pin is in axial alignment with
the plunger 87 actuated by a coiled spring 88. The plunger works within a
longitudinally disposed chamber 89 in the locking block 68. From one side of
it projects through the wall, through a slot 90, a plunger stud 91. The stud 91
is employed in practice to compress the spring 88, and the length of the slot 90
limits the forward movement of the plunger 87. The plunger serves, when in-
pelled by the force of the spring 88, to deliver a blow against the end of the
firing pin 85, which, in turn, strikes the cap of a cartridge confined within the
breech chamber.
The forward end of the plunger 87 is conical in form, as indicated at 92, and
the adjacent end of the breech block 63 is provided with an inversely conical de
pression 93, which being concentric with the firing pin 85 is adapted to receive
the conical end 92 of the plunger.
The breech block 63 is provided with a spring hook or catch 95, which, being
firmly secured in place, as by a screw. 96, (see Fig. IX) is adapted, when the breech
block is forced in place behind a cartridge, to engage the rim or heel of the

page_text: cartridge so as to withdraw the cartridge, or an empty shell, after firing, from the
breech chamber.
In connection with that, or other suitable means, for engaging the rim of the
cartridge I employ a positively movable ejecting member, located to one side of
the rim. The firing pin 85 fulfils the condition as to location which, although
located concentric with the shell, is nevertheless eccentric with respect to the rim.
I, therefore, adapt the firing pin as the ejecting member, by providing upon
one side of it a lug or extension 97, that works in a slot 98 (see Fig. IX). The
slot 98 is, for convenience, located in the top of the breech block 63 and, as shown
in Fig. XVIII, the lug 97 works in a groove 99 in the inner side of the upper
wall of the frame. The slot 98 serves to limit the forward movement of the firing
pin 85 under all conditions.
As previously specified, the breech block is adapted to reciprocate within its
groove 70 in axial alignment with the barrel 3. Consequently, as it approaches
the rearward limit of its travel, the edge of the lug 97, within the groove 99,
strikes the end or stop shoulder 100 of the groove and by a positive movement
impels the firing pin 85 against the end of the cartridge or shell, thereby causing
it to turn with great force at the point where it is confined by the hook 95, and
ejecting it through the ejecting aperture 62 (see Fig. XXVI).
I have inserted at this place the description of the cartridge ejecting mechanism,
because it serves to explain one of the conditions upon which the initial down-
ward movement of the locking block, in a measure, depends; that is to say, when
the cartridge is in the breech chamber, and the hook 95 on the breech block 63
is forced into engagement with its rim or heel, the breech block is securely attached
to the cartridge so as to insure the withdrawal of the cartridge through the rear-
ward movement of the breech block.
Now, the fit of the cartridge within its chamber is in practice, especially after
the explosion of a shell, so close to require some force to extract the shell.
It is apparent that the first movement of the locking block 68 from the position
which it occupies, as shown in Figure IV, for example, must be downwardly, no
rearward movement being, in the first place, possible. The limit of the initial
downward movement is shown in Fig. XXI of the drawings. From the position
shown in Fig. IV, for example, to that shown in Fig. XXI, the movement of
the locking block is made entirely upon the pintle 65.
I avail myself of this initial movement to start the cartridge or shell from its
chamber. To accomplish this, I provide a fulcrum extension 101 upon one side
of the bifurcated end 66 of the locking block 68 (see Fig. VIII as to details of
construction), bearing against an abutment face 102 on the forward end of the
frame, so that the locking block in turning upon the pintle 65, as a pivot, secures
a leverage through the engagement of the fulcrum extension 101 against the
abutment face 102, to loosen the cartridge or shell from the chamber. After it
is loosened, the shell requires no material force to completely withdraw it from
the breech chamber.
The locking block in making its descent from the position shown in Fig. IV to
that shown in Fig. XXI, makes the first movement preparatory to cocking.
I shall, therefore, proceed to describe the mechanism by which the plunger 87
'is employed to compress the spring 88, to hold it in place until the gun is to be
discharged, and for its release when the discharge of the piece is to be effected.
The practical efficiency of my gun requires that its operation should be accurate
and rapid in action, that is to say that with each complete reciprocation of the
hand grip 52 all the functions necessary to the ejectment of an empty shell, the
re-loading, and the cocking of the gun should be completed.
For that reason I propose to employ in the present connection suitable
mechanism which shall, at the expense of the least possible force during the for-
ward movement of the feed slide provide for the cocking of the gun; that is to
say, the compression of the spring 88 and detention of the plunger 87.
As shall hereinafter be specified, the locking block in its downward and rear-
4

page_text: ward travel performs distinct functions as a component part of the magazine feed
mechanism, but at present it is to be considered solely as to its operation in com-
pressing the spring 88 and detaining the plunger preparatory to firing the piece.
The operation under consideration is substantially accomplished in the manner
illustrated in full lines in Figures XVIII and XXI to XXIII, inclusive, of the
drawings. The last rearward and downward movement of the locking block in
which it proceeds from the position shown in Fig. XXIII, to that shown in
Fig. V, for example, is designed for performance of functions independent of the
cocking function. For that reason, I shall refer specially to
the figures
enumerated.
Let it be borne in mind in this connection that the plunger-stud 91 upon the
locking block 68 should be unimpeded in its progress during the rearward travel
of the locking block, that it should be caught and forced to the rear of the slot 90
during the ascending movement of the locking block, and that it should be de-
tained in the position last specified, which represents the cocked position, as
shown in Fig. XVIII, until the piece is to be fired.
As preferred means for accomplishing the objects referred to in the foregoing
paragraph, I provide suitable mechanism upon the inner face of the side plate 60,
and show two modified forms of embodiment of mechanism for the purpose. The
preferred form of side plate is illustrated in Fig. XXV, and the modified form
in Fig. XXVII.
I also show a still further modified from in Figures XXIX to XXXI of the
drawings, but as those figures illustrate the change of location of several of the
parts, rather than a mere modification of the side plate, I shall reserve description
of the subject matter of the last named figures to a subsequent part of the specifica-
tion.
The preferable form of side plate illustrated in detail in Fig. XXV is provided
on its inner face with a somewhat extensive depression 105, which, being of a
depth to accommodate the extent of the plunger stud 91 affords an open field for
the movement of the plunger stud as it accompanies the locking block on its
downward and rearward movements. The first movement of the locking block
from the position shown in Figure XVIII to that shown in Fig. XXI is, down-
wardly the locking block being swung upon the pintle 65, as already specified.
The plunger stud 91 is accommodated to this movement by the forward curved
wall 106 of the recess 105. Adjacent to the wall 106 a channel is defined by the
sear 107 that is pivoted, as indicated at 108, to the side plate 60, and is provided
(see also Fig. X) with an externally defined, slightly oblique groove 109, its bi-
furcated end 110 being substantially flush with the upper or pivoted portion of
the sear.
The pivot 108 is located to one side of the main body of the sear so that
the sear drops normally, under gravity, below the lower edge 111 of the ejecting
aperture 62.
The outer wall of the groove 109 works in a recess 112 formed in the side
plate 60 in the bottom of the recess 105, and the movement of the sear upon its
pivot 108 is circumscribed by the walls of the recess 112. A recess 113 extends
flush with the bottom of the recess 105 to the lower edge of the plate 60 and
admits the bulbous head 114 of the trigger 115, that is pivoted, as indicated
at 116, within an aperture 117, in the lower wall of the frame 1, to engage with.
the bifurcated end 110 of the sear. The trigger is protected by the usual
guard 118.
The details of the trigger are shown in Fig. XXI, and its connection and
relation to the sear are clearly illustrated in Figures XXI to XXIII, as well as
upon other figures of the drawings.
The curved face 119 of the sear is almost concentric with the curved wall 106
of the recess 105, so that as the locking block in its initial downward movement,
as shown in Fig. XXI, carries the plunger-stud 91 with it, it guides it between
the walls 106 and 119 of the recess 105 and the sear, respectively. The further
downward and rearward movement of the locking block, as indicated in dotted

page_text: lines in Fig. XXI, causes the stud 91 to enter the groove 109 in the sear. The
groove being inclined, the sear is slightly turned upon its pivot 108, as indicated
in Fig. XXI. After the plunger stud clears the groove 109, the sear again
drops by gravity substantially to the position shown in Fig. XXV. Consequently,
when the locking block, upon its return movement, advances from the position
shown in full lines in Fig. XXIII to the position shown in dotted lines therein,
the plunger-stud 91 strikes the sear, as shown in Fig. XXIII above the
groove 109. impinging against the face 120 of the sear. Under the impulse of
the stud 91 the scar tilts slightly upon its pivot, but detains the stud, the latter
rising against its face as the locking block is forced into position, until, when
it reaches the position shown in Fig. IV, the stud 91 has been forced back to
the end of the slot 90 in the locking block, and is held in that position through
engagement with the upper end of the face 120 of the sear, as clearly indicated
in dotted lines in Fig. IV. In that position the gun is cocked ready for firing.
A pull upon the trigger tilts the head 114 which, engaging with the bifurcated
end 110 of the sear, causes the sear to turn slightly upon its pivot, thereby de-
pressing the end of the face 120 from the path of the stud 91 and releasing the
spring 88. It may be noted here that the interior of the side plate 60, as shown
in Fig. XXV is provided with a groove 121, which permits the free, rearward
movement of the breech block 63 without interfering with the laterally pro-
jecting hook 95 upon the block. That is merely a detail of construction adapted
to accommodate the particular form of block employed.
In Figures XXVII and XXVIII a slightly modified construction of side plate
is illustrated. Although the contour of the side plate is the same as that of the
side plate 60, yet, for the purpose of distinction, I shall indicate the side plate
shown in that figure by the reference numeral 122. The side plate 122 is pro-
vided with an endless groove, which consists of the nearly vertical portion 123,
the rearwardly inclined portion 124, the obliquely ascending portion 125, the
vertically ascending portion 126, and the horizontal portion 127. The plate 122
is recessed at right angles to the part 127 of the groove to carry a sliding sear 128,
which reciprocates within fixed limits imposed by the engagement of the pin 130
projecting from the plate with the ends of the longitudinal slot 129 in the scar.
The sliding sear 128 is cut away in its lower part below a shoulder 132 so that its
face, below said shoulder, shall be flush with the bottom of the groove 124 in
order to permit the free travel through the groovel 124 of the plunger-stud 91.
The lower end of the sliding scar 128 is provided with a pair of laterally project-
ing jaws 133, which receive between them the arm 134 of a trigger 135, which is
of general bell crank construction, and is pivoted, as indicated at 136, within an
aperture 137 in the frame 1. A spring 138 serves to normally support the
trigger in position to hold the sliding sear 128 at the upper limit of its movement.
The purpose of the side plate 122, with its endless groove and sliding sear,
is as follows:
:
groove
The locking block operating as previously described carries the plunger-stud 91
downwardly in its first movement through the portion 123 of the endless groove;
thence it is guided by the groove 124 bevond the point of juncture of that
with the groove 125. The locking block pursues in its downward and rearward
descent, a course defined by the direct pull upon the link 71. This may be called
its normal course, but its movement may be somewhat modified if another guiding
force be interposed. The groove 124 performs the office of changing the normal
course of the locking block in its downward and rearward movement. The 5
groove 125 is located so as to be in substantial alignment with the plunger-
stud 91, when the locking block is pursuing its normal course. Consequently,
after the stud 91 leaves the groove 124 and enters the enlarged space 139 at the
juncture of the grooves 124 and 125, the stud 91, upon the return, or ascending
movement of the locking block, follows the course of the groove 125, which guides 5
it through the groove 126. When the stud reaches the top of the groove 126.
the locking block, as shown in dotted lines in Fig. XXVII, is then in place behind

page_text: the cartridge, and in position for firing. When the stud 91 enters the groove 127
from the groove 126 its movement is arrested by the upwardly projecting end of
the sliding sear 128, as clearly indicated by dotted lines in the figure last referred
to. In that position a pull upon the trigger serves to draw the sliding sear 128
downwardly from in front of the stud 91, and releasing it, to allow the plunger
to slip forward under the impulse of the spring 88 to fire the gun.
As shown in Fig. XXVIII, the stud 91 is a cylindrical pin instead of rect-
angular, as shown in the other figures, but this is a mere mechanical variation.
The groove 121 is also shown as omitted from the side plate 122, but that groove,
as above explained, is merely employed to accommodate a particular form of
construction of the breech. block, and is not essential to the side plate proper.
Although my gun has been described as belonging properly to the type of
magazine guns, yet it is a desirable feature in guns of, that class that they should
include means for introducing a single shell from time to time, as required, and
my gun, as above specified, is adapted to be used as a single fire gun, by inserting
a cartridge through the ejecting aperture 62. I nevertheless contemplate the
employment of magazine feed mechanism for conveying cartridges from the maga-
zine chamber to the breech chamber in the barrel.
In the preferred form of embodiment my invention, as illustrated, the magazine
chamber is located in the stock and communicates with the breech chamber
through a deflected, preferably laterally deflected, passage.
It will have been understood, however, from the brief description already
given, of the operation of the feed slide 35, and the cartridge carrier section
secured thereto, that the feed slide may operate to extract a cartridge from the
magazine chamber and present it in front of the breech block at whatever point
upon the gun the magazine chamber may be located. In other words, while I
prefer the entire construction, as illustrated, I do not wish to limit the scope of
my invention to any particular location of the magazine chamber, or to the
operation of the feed slide, with respect to any such particular location of the
magazine chamber.
As previously specified, the means of communication from the cartridge chamber
defined by the recesses 22 and 23 is through a continuous cartridge passage ex-
tending from an aperture in the butt plate 11 into and through the channel 58
in the side of the frame 1.
Within grooves 45 in the two parts of the stock travels the cartridge carrier
section of the feed slide. The cartridge carrier section is provided with mechanism
for feeding the cartridges one by one from the magazine chamber through that
portion of the passage defined by the deflecting plate 56, and for advancing the
foremost cartridge into the channel 58, after reaching which the cartridges are
advanced and delivered into the chamber by mechanism carried upon the locking
block.
To adapt it to the performance of the functions recited, the cartridge carrier
section 40 is provided at intervals of required distance with yielding supports
or feeders 140. They preferably consist of spring metal plates provided with bent
angular heads 141, the plates being secured at one end, as at 142, (see Fig. XII)
to the under side of the cartridge carrier, and the heads working through longi-
tudinal slots 143, in the body thereof. As illustrated, two heads are shown,
their office being to advance cartridge E into the position of cartridge D, (see
particularly Figures XV and XVII) and cartridge F into the position vacated
by cartridge E.
To accomplish this object, the carrier 40 is, through the manipulation of the
hand grip 52, forced to, or nearly to, the rearward limit of movement shown in
Fig. VII, in which the lowest of the series of cartridges X contained within the
magazine chamber slips in front of the rearward feeder, thereby assuming position
of the cartridge F, with the point of its ball resting upon the forward feeder.
If, now, the hand grip 52 be advanced to the position shown in Figures IV
and VI, cartridge F will be carried into the position of cartridge E, and another
B

page_text: of the series of cartridges X will take the place of cartridge F. At the same time
the forward feeder will urge the cartridge ahead of it into the position of cart-
ridge D (see Fig. XVII).
To secure a further advance of the respective cartridges the reciprocatory move-
ment of the cartridge carrier 40 must be repeated, and so on from time to time,
until the cartridge in the magazine chamber are exhausted, after which, of
course, continued reciprocation of the carrier 40 will advance the last cartridge F
through the successive positions.
In order to prevent the backward movement of cartridges D and E, it is neces-
sary to provide means for holding them in the positions represented by those
letters, and for that purpose I provide yielding detents 145, 146, respectively,
secured within the stock, as for example, to the side piece 7 within the re-
cesses 147 and 148, respectively. The heads 149 and 150 of the yielding detents
correspond substantially to the shape of the heads of the feeders 140, and are
located in adjacent positions to them when the carrier 40 is at its forward limit
of movement, as shown in Fig. XVII. It will be understood from the foregoing
description, by reference to the drawings, that the cartridges are successively im-
pelled through the cartridge passage, by the feeders 140, the detents 146 and 145,
respectively, yielding to permit them to pass. On the other hand, the cartridges
.being in position, when the carrier 40 is forced to the rear the heads of the respec-
tive detents hold the cartridges, while the head of the forward feeder 140 yields
to permit the backward movement of the carrier.
I also provide a terminal yielding detent 151, that is secured, as indicated at 152
to the upper wall of the extremity of the cartridge passage, and whose curved
head works in a recess 153 therein. The office of the terminal defent is to guide
the cartridges of the series X, successively into the position of the cartridge F. It
also serves, as illustrated in Fig. XIV, to a ist the rearward feeder 140 in filling
the magazine chamber in the act of loading. In that operation the point of the
cartridge is first elevated by the feeder, as shown in dotted lines in Fig. XIV, and
when the next cartridge is introduced, the feeder is compressed, so that when the
heel of the cartridge passes the terminal detent the cartridge is delivered well into
the magazine chamber against the bent arm of the spring 28.
Assume now that the cartridge passage contains at least the cartridge D, the
mechanism being in the position shown in Figures IV, VI and XVII, for
example, and that the cartridge carrier is then shifted to the rearward position,
as shown in Fig. VII, for instance. In that movement of the carrier, the
detent 145 restrains the rearward movement of the cartridge D and holds it in
position. When the next forward movement of the cartridge is made, a yielding
feeder 155 carried upon a lateral extension 156 at the forward end of the cartridge
carrier (see Fig. XII) impinges against the base of cartridge D and advances
it under the deflecting plate 56 into the channel 58 to the position C, in which
position, as clearly shown in Fig. XVIII, the heel of the cartridge is introduced
just within the lower end of the channel 58. In advancing cartridge D to
position C, the feeder 155 depresses a spring detent 157 (see Figures IV and V)
which, as the cartridge slips into position C holds it in place against the back-
ward movement of the carrier.
After the cartridge reaches the position C it ceases to be operated upon by the
feed slide, but is thence-forward actuated by mechanism directly connected with
the locking block. The means employed for advancing cartridge C to position B
is a swinging feeder 160, pivoted, as indicated at 161, within a recess 162, in the
side of the locking block next to the channel 58 (see Fig. VI). The swinging
feeder 160 at its free end, carries a small stud pin 163, clearly shown in Figures XV
and XVII, which, impinging against the heel of cartridge C. the feeder 160
swinging with the movement of the locking block to hold it in that position
behind the cartridge, forces the cartridge into position B. Compare Figures XV
and XVII, in which the two positions are illustrated. The movements of the

page_text: swinging feeder 160 are clearly illustrated in dotted lines in Fig. XX of the
drawings. As appears particularly in that figure, the opposing edges 164 and 165
that denne the interior open portion of the channel 5S (compare also Figs. XXII
and XXIV) engage alternately the stud pin 163 (the pin being urged into en-
gagement therewith by the curvature and resiliency of the swinging feeder, as
indicated in Fig. XV of the drawings), and guide the stud pin in the rearward
and forward movement of the locking block into engagement with the heel of a
cartridge lying in its path; that is to say, the cartridge C.
As is clearly illustrated in Figures XV and XVII of the drawings, the point
of the cartridge C is supported upon a yielding detent 166, whose rear end is
secured, as indicated at 167, to the interior of the side wall of the channel 58,
and whose free end is curved inwardly, as shown. The detent 166 is swept aside
by the forward movement of the cartridge C while it is being impelled by the
swinging feeder 160, but, when the cartridge completes its forward movement,
and reaches the position marked B, the detent 166 rises behind it and holds it in
place. When advanced to the position B in the movement described immediately
above, the cartridge is presented to a yielding delivering sheath 168, that is
secured, as indicated at 169, to the inner wall of the channel 58, and whose free
end is provided with a retaining member 170, designed to guide the cartridge B
into the breech chamber. The retaining member 170 holds the cartridge loosely
after the manner in which it would be held in the palm of the hand, the resiliency
of the metal of which the sheath is composed being sufficient to elevate the point
of the cartridge substantially in axial alignment with the breech chamber. The
inner edge 171 of the retaining member 170 is smooth and curved, and is designed
to make contact with the wall of the locking block, in such a manner that the
locking block may move freely and uninterruptedly over it depressing it into the
forward recess 172 of the chamber 58, when the locking block is advanced to
the firing position, as shown in Figure XVII, or relieving it and allowing it to
move to the position shown in Figure XV, when the locking block is retracted.
The locking block carries upon the shorter leg of its bifurcated end 66, a yield-
ing feeder 174 (compare Figures VIII and XV) that is compressible within a
recess 175 in the end of the locking block, clearly indicated in Fig. XV. The
feeder 174 yieldingly passes over the heel of cartridge B, as the locking block
passes towards the position indicated in Fig. XV. When reaching that position
it springs in behind the cartridge, as shown in that figure, and with the return
movement of the locking block, assists the breech block to drive the cartridge into
the chamber, as clearly illustrated in Fig. XXIII of the drawings. The cartridge
in that figure is lettered B, it being shown in the act of passing from position B
to position A within the breech chamber.
An important feature of my invention in this connection consists in the pro-
vision made for deflecting the point of each cartridge in the cartridge passage
from the fulminate cap of the one in front of it. The several feeders and detents
serve to perform that office. The points of the cartridges are deflected some
laterally, and some of them vertically, but an examination of the different
positions, as illustrated, of the several cartridges will serve to explain my object.
The rearward feeder 140 and the detent 146 co-operate to deflect the point of
cartridge from the cap of cartridge E. In like manner the forward feeder 140
and the detent 145 deflect the point of cartridge E from the top of the cap of
cartridge D. Detent 157 and feeder 155 deflect the point of cartridge D from cap
of cartridge C (compare Figure XVII with Figures IV and V). Detent 166 co-
operates with swinging feeder 160 to deflect point of cartridge C from cap of
cartridge B.
The object of deflecting the point of each cartridge from the cap of its advance
neighbor is to prevent possibility of accidental explosion of cartridges within
the magazine through shock or jar derivable, for instance, from the recoil of the
gun. The point of cartridge B is always confined within the chamber 172 of the

page_text: channel 58, when the locking block and breech block are in place, and can never
come into line with the cap of cartridge A, except when the cap of cartridge A
is exploded, or the parts of the gun are in the inoperative position.
In Figures XXIX to XXXI of the drawings, I illustrate a form of embodiment
of my invention, the object of which is to change the position of the trigger of
the gun, locating it nearer the central part of the grip, instead of directly under
the frame.
Referring to these figures:
176 indicates a modified locking block, substantially identical in all respects
with the locking block 68, both as to form and manner of operation, except that
instead of a plunger, it contains an intermediate firing pin 177, which communi-
cates at its forward end with the firing pin 85, and is actuated from the rear by
a plunger 178, which travels in an obliquely disposed guide way 179, in a
thickened portion or housing 180 of the frame, deriving its impulse from a coiled
spring 181 corresponding in function to the spring 88 previously described.
The locking ock 176 carries upon one side a stud pin 182, that works in a
groove in the side plate 183. The groove consists of a vertically inclined sec-
tion 184, an obliquely inclined section 185, extending parallel to the guide
way 179, a deflecting section 186, and a tail guide section 187. Within a
recess 188 that extends under the deflecting section 186 of the groove is pivotally
mounted, as indicated at 189, a sear 190. The scar is provided with a detaining
arm 191 and a bifurcated arm 192. The latter engages with the trigger 193,
identical in form with the trigger 115 previously specified. The round, upper
corner of the locking block 176 is designed to impinge against the plunger
stud 195, which projects from the plunger 178 through a slot 196 in the
housing 180. This it is compelled to do while the pin 182 moves in the sec-
tion 185 of the groove in the sear plate. Consequently, the rearward movement
of the locking block during the engagement of the stud 182 with the section 185
of the side plate tends to drive the plunger 178 rearwardly, and to compress the
spring 181. When, however, the spring is sufficiently compressed, the plunger
stud 195 is driven beyond the detaining arm 191 of the sear which, by gravity,
or other acting force as may be preferred, rises in front of the plunger stud.
The oscillation of the sear being limited by the side walls of the recess 188, the
sear is adapted to intercept the plunger stud 195 and prevent, so long as it is
interposed, its forward movement. At about the same time as the plunger stud
is forced to the rear of the detaining arm 191 of the sear the plunger stud 182
is guided downwardly by the deflecting section 186 of the groove and compelled
to enter the groove 187 of the side plate and retire from in front of the plunger
stud 195, leaving it resting solely against the detaining arm 191 of the sear.
the returning movement of the locking block, the curved end of the locking
block passes freely under the plunger stud 195, permitting the locking block to
be restored to the firing position, whereupon, the piece is ready to fire through a
pull upon the trigger 193 in the usual manner. The pull upon the trigger tilts
the sear upon its axis 189 and releases the plunger stud 195. The plunger ad-
vances under the force of the spring 181, and, striking the end of the intermediate
firing pin 177, communicates the force of the blow through the firing pin 85 to
the cap of the cartridge.
In
In Figures XXXII to XXXIV, inclusive, I illustrate a form of magazine
chamber which may be called in this connection an auxiliary magazine or cart-
ridge chamber 198. It is designed to carry an auxiliary supply of cartridges,
which may be supplied to the cartridge feed mechanism after the supply in the
primary magazine chamber is exhausted. In order to accommodate it to this
office I provide in its lower part cartridge supporting mechanism, which consists
of a rotatable disc 199 connected, as by links 200, with supports 201 that work
in slots 202 in the side walls of the chamber. The disc is mounted upon a
spindle 203 which may be actuated by an arm 204 that fits snugly within a recess

page_text: provided for it upon the outside of the stock. A retaining pin 205 may be em-
ployed for holding the arm in place.
In the form of stock illustrated in Figures XXXII to XXXIV, inclusive, the
cartridges may be supplied to the primary and auxiliary chambers through hinged
doors 206 and 207, for example.
In the foregoing description I have, from time to time, pointed out the mode of
operation of the several elements and groups of elements, and now subjoin a brief
description of the general operation of my gun.
In loading the magazine chamber, the hand grip 52 is brought to the position
shown in Fig. XIV, in which position the rearward feeder 140, and the terminal
detent 151 are located so as to force the cartridges into the magazine chamber as
they are pushed into the cartridge passage through the feed aperture 12 in the
butt plate. When the magazine chamber is filled, or before the hand grip is
forced to the limit of its backward movement (see Fig. VII), in which position
the cartridges forced in through the aperture 12 are pressed down against the
carrier section 40 of the feed slide and may be advanced over the yielding detents
and feeders by the introduction sucessively of a fresh cartridge from the rear.
The cartridge passage and magazine chamber may, in the first place be both
filled with cartridges, although that is not necessary to the operation of my gun,
inasmuch as one cartridge supplied in front of the feeder 140 will be carried for-
ward through the cartridge passage into the breech chamber whether others are
present in the passage, or not. Assuming that the cartridge passage and the
magazine chamber are supplied with cartridges, the alternate backward and for-
ward reciprocation of the hand grip 52 will suffice to run the entire supply of
cartridges through the gun. With each backward reciprocation of the hand
grip a cartridge from the breech chamber, if it contains one, or a shell, if the
cartridge has been exploded, will be ejected, as illustrated in Fig. XXVI, from
the ejecting aperture 62. With each forward movement of the hand grip 52,
as long as the recess 172 of the chamber 58 contains a cartridge, the breech
chamber will be supplied, and the gun may be fired by pulling upon the trigger.
The piece, however, may be fired with safety, and with great rapidity, by retaining
a constant hold upon the trigger, so that the locking block 68 is forced into place
and the plunger 87 is driven forward simultaneously. It will be understood
from an examination of Fig. XXIII, for instance, how this may be accomplished
with safety. In that figure, in dotted lines, it appears that the plunger stud 91
engages lower down upon the face 120 of the sear and slides along the face 120
while the locking block is being driven into the firing position. The movement
of the sear is limited in such manner by the walls of its recess 112 (see
Fig. XXV) that it cannot release the plunger stud 91 until at the precise moment
when the locking block is forced into the firing position, and secured there by
the interposition between it and the frame of the link 71.
While I have illustrated and described in detail a preferred form of embodi-
ment of my invention, and have pointed out certain special modifications, yet I
consider that the form of embodiment illustrated and described is susceptible,
within the scope of my invention, of various modifications not pointed out in
detail, and, wishing to enjoy to the fullest extent the right to substitute equiva-
lent mechanism where I may hereafter desire to employ it, have endeavoured in
describing the elements, of which one of a variety of forms has been selected, to
indicate the choice or preference by the language employed in the description
of the parts.
