Improvements in Magazine Bolt Guns.
We, GUNERIUS SCHOU, of 65, Meyers Gade, Christiania, in the Kingdom of Norway,
Gunsmith, ANDREW MARTIN CARLSEN, of 279, Williams Street, St. Paul, in the State
of Minnesota, United States of America, Patent Attorney, and ALBERT PRESTON
HENDRICKSON, of 22, East 4th Street, St. Paul, aforesaid, Contractor, do hereby
declare the nature of this invention and in what manner the satne is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to improvements in magazine bolt guns; and the objects of
our invention are, first, to simplify a rifle or similar gun so that its working parts
shall be very few in number; second, to so construct the working parts of a rifle or
gun that they may be taken apart for cleaning and repair and put together again
without tools, both of which points are obviously of great advantage both in the
manufacture and the use of the gun; third, to provide a gun in which all the working
parts are very durable and reliable, and not apt to get out of order; fourth, to pro-
vide a gun in which the magazine may be filled with cartridges almost in an instant
by simply dropping them in, without the resistance of springs, as is usually the case
in guns heretofore used; fifth, to so simplify the mechanism of a gun. that any ordi-
nary person may readily understand to use it as well as to take it apart for
cleaning &c.
These and other objects we attain by the novel construction and arrangement of
parts illustrated in the accompanying drawings, in which

Referring to the various parts in the drawings by reference numerals, 1, designates
the stock or woodwork of the gun, 2, is the barrel which is screw-threaded at 3, into
the front end of a metallic body or frame 3, 4, 5, of which the upper portion forms
the receiver, the lower portion the magazine and the rear portion houses the
hammer and other working parts. The magazine for the cartridges is the annular
chamber 7, extending between one-half and three-fourths of a circle around the
receiver and has its front and rear end terminated by the annular walls 8, and 9,
projecting transversely out from the outer curved wall 10, of the receiver 4, (best
shown in Figs. 8, 9, and 10). The curved bottom 11, and left side wall 12, of the
magazine are made integral, and secured in place by the insertion of the ends 13, of
the portion 12, upward into the straight grooves 14, in the left extremities of said
end walls, 8, and 9, and by the stock 1, below it. The right side of the magazine is
provided with an opening 15, which may be closed or opened so as to receive the
cartridges sidewise into the magazine by moving up or down the curved lid 16, which
slides with its ends in the curved grooves 17, in said end walls of the magazine. 18,
is an out and upwardly projecting edge of the lid, by which it is operated; in Fig. 9,
is shown in dotted line 18x, the position of the lid while the magazine is being filled.
19, is the opening through which the cartridges enter from the magazine into the
interior cylindrical space 20, of the receiver in front of the breech bolt 21, which will
presently be fully described. Upon a downwardly projecting stud 22, swings pivotally
the arm 23, which extends through the slot 24, in the wall 9, into the magazine
where it is provided with a downwardly projecting arm 25, and a long, limber, upwardly
curved spring arm 26, with a head 95, secured on its end; this arin is the cartridge
carrier, which tends at all times to move the cartridge upward into the receiver
and is therefore also urged sidewise by being swung on its pivot 22, by the L-shaped
carrier spring 27, inserted with its offset end in the side cover 12, as shown at
28, in Figs. 1 and 7, and presses with its L-shaped end 29 against the side of
the carrier. The magazine lid 16, is provided in its lower front corner with two
notches 30, and 31, (see Figs. 7, 8, and 12) of which the notch 30, is a clearing
to allow the tooth 25, of the carrier to swing from side to side; the other
notch 31, engages by its rear shoulder the said tooth 25, as shown in Fig. 12,
and thereby positively locks the carrier which, being spring-pressed assists in
holding by frictional contact the lid in the open position 18%, in Fig. 9, with the
head 95, of the carrier standing back as to the left in the view into the cavity 32, in
the side lid 12, (as shown in dotted line in Fig. 9), thus leaving the magazine open
and unobstructed so that all the cartridges it will hold can be dropped sidewise down
into it in a moment, and as the lid is touched upward again it closes and the gun is
ready for firing.
The cartridge cut-off (best shown in Fig. 18), and in the front end view Fig. 17),
consists of a small rock-shaft 33, provided near its middle with the thumb catch or
ram 34. The front end of this shaft is cut away forming a half round 35, which will

page_text: alternately present its round or flat side to the cartridges and thus will either prevent
them from or allow them to enter the receiver, according to how the shaft is turned
by the catch 34. The front portion 35, of the shaft is inserted in a hole 36, in the
upper wall of the receiver, so that it may present its round side to the cartridge when
in the position 36*, as shown in Fig. 9. The rear end of the shaft is journaled in a
lip or projection 37, formed upon the rear end of the receiver, and provided with the
notch or gap 38, for the arm 34, to pass through in extracting and inserting the shaft.
In the lower side of the rear half of said rock-shaft is inserted and secured a spring
arm 39, of which the downwardly curved front end 40, engages the transverse
groove 41, and by frictional contact holds the shaft in the desired position, as well as
prevents its accidental withdrawal.
The breech bolt 21, provided with the operating arm 42, is in its lower side
provided with a longitudinal groove 43, closed at its front end and having its rear
end broadened into a wide notch 44. The ejector 45, (best shown in Figs. 8, 13, 14)
is a small two-armned lever pivoted in a short groove 46, in the bottom of the breech
(see Fig. 8). Its short end projects upward into the groove 43, of the breech bolt
and allows the long front end to sink down into groove 46, but when the breech
bolt is pulled back to its full limit the solid front terminus 42* of the groove 43,
depresses the short end of the lever, causing thereby its front end to knock the
empty cartridge upward and out of the receiver, and when the breech bolt is pushed
forward and turned to the right so as to cause its locking lugs 47, and 48, to enter
the locking notches or cavities 49, and 50, in the upper wall of the receiver, and the
arm 42, to enter the notch 43*, in the side of the receiver, the ejector occupies the
wide portion 44, in the under side of the breech bolt. Between the cheek plates 51,
of the frame is mounted on the two plain pivots 52-53, the hammer 54, and the
trigger 55. The main spring 56, (best shown in Fig. 8), is connected with the
hammer by the stirrup 57, and is further held in place by the cheeks 51, and
the notch 58, in the rear end wall of the receiver. 59, is the trigger spring which is
secured with its upper end to the rear tang 60, of the frame and presses with its
lower end forward against the trigger.
The breech bolt 21, houses in its round, central opening 61, the firing pin 62, of
which the front end 63, is reduced as usually, and its main body is round, while its
rear end 64, is four-cornered as far as to the rigid collar 65, with which the pin is
provided. This collar is housed in a cylindrical cavity 66, formed in the reduced
end 67, of the breech bolt, which projects rearwardly beyond the operating lever 42,
the bottom of said cavity 66, and the front side of the collar 65, are both provided
with cams as 68, which, when meeting the tops of one another, keep the firing pin
retracted, so it cannot touch the cartridge, but if the breech bolt is turned so that
its cams 68, register with the spaces between the cams, on the firepin, the latter is
at liberty to be thrown forward by the blow of the hammer upon its rear end, and
will then operate on the cartridge. The necessary turning of the breech bolt for
said purpose, takes place every time the breech bolt is rocked about one-eighth of a
turn to the right to interlock it in the receiver, and back so as to allow its retraction;
the firing pin is prevented from rocking or turning by having its square end inserted
in the square hole 69, in the rear end portion 70, of the cartridge extractor 71,
which portion is provided with the cylindrical cavity 72, fitting upon the projection 67,
of the breech bolt. The tongue 73, of the extractor, engages the annular groove or
recess 74, at the base of the operating lever 42, (best shown in Figs. 21 and 24).
The front end of the extractor bar 71, is brought down to the side of the front end of
the breech bolt, which it projects slightly beyond and is formed into the hook 75,
adapted to take hold in an annular groove near the rear end of the cartridge, and
extract it from the barrel after it is fired. Upon the right side of the extractor bar
near its front end, is provided the stop 76, which, when the breech bolt is pulled
back, catches against the rear terminus of the note' 50, in the upper part of the
receiver; this notch is shown in Fig. 8, and in Fig. 2, it is indicated in dotted line
that its front end is open in order to receive said catch or projection 76. 77, is a
clearing in the front end of the receiver for the hook 75, of the extractor to pass

page_text: into and reach the regular notch (not shown) in the end of the barrel and get a hold
of the cartridge.
The hammer is raised by the pressure against its front side or projection 54%, of
the square rear end 78, of the hammer lifter 79, (shown in Figs. 5, 6, and 8,) which
is of almost semi-cylindrical shape, with a diagonal front cam-edge 80, of which the
rearmost end terminates in the notch 81, and the front end, in the squared-off
point 82. 83, is a catch projecting from the under side of the hammer lifter, and
serves to prevent the latter from dropping out accidentally, when the breech bolt is
removed. This haminer lifter is located in the recess 84, (best shown in the plan
view Fig. 4), milled out for it in the receiver, so that its upper or inner curved face
fits the lower face of the breech bolt. When the hammer lifter is inserted into said
recess, the catch 83, on its bottom, is clipped down into the deeper recess 85; said
recesses run diagonally and parallel with the front edge 80, of the hammer lifter,
which bears against the front terminus 86, of the recess 84. When the parts are put
together and the breech bolt is pushed forward, the hammer lifter fills the space
between the shoulders 89, and 90, in Figs. 19, and 20, so that it is bound to rock
with the breech bolt, and thus be moved forward by the diagonal recess and leave
the hammer free to work when the breech bolt is turned to the right and interlocked,
and at no other time; and by raising the arm 42, preparatory to pulling the breech
bolt back, the hammer lifter is by the co-action of the diagonal cam-edges 80,
and 86, forced rearwardly against the hammer, which is thereby raised to its full
limit. When the breech bolt is pulled back the hammer lifter is prevented from
turning by having its notch 81, held by the hammer forward against the projec-
tion 91, adjacent thereto in the recess 84, in the receiver; when the breech bolt is
again moved forward and turned to the right the hammer lifter turns with it and
releases the hammer, which, after losing the support of the lifter, depends on the
trigger to hold it up and is thus ready to strike when the trigger is pulled.
92, is the opening in the receiver through which the empty cartridges are ejected,
and 93, is the slot in rear thereof in which the extractor bar 71, guidingly slides
back and forth.
In the above description the operation of the gun is already fairly explained, it
may however be further stated that when the magazine is filled with cartridges and
the cartridge cut-off is turned so as to allow the cartridges to enter the receiver, the
operator simply takes hold of the arm 42, raises it up, pulls it back so that the
cartridge can slip partly sidewise into the receiver, he then pushes the breech bolt
forward and locks it by turning it to the right, then pulls the trigger, and after thus
firing one shot he repeats the operation with the breech bolt and the trigger just as
fast as he wishes, and is able to, and everything works automatically until the
magazine is empty, when he refills it the way above described. In pulling the
breech bolt back quickly, the empty cartridge, which follows the hook 75, of
the extractor, is thrown out of the receiver by the ejector 45, as already described,
and when the breech bolt is moved forward, its right front edge adjacent to the
mouth 19, of the magazine takes hold of the edge of the rear end of the cartridge
and moves it forward while the next cartridge or the cartridge carrier itself, urges it
inward until it is freed from the retaining lip 96, and assumes a central position,
with, and is pushed toward the center of the receiver. The inclined plane or
shoulder 97, at the rear end of the receiver, serves to guide the arm 42, quickly into its
locked position, and in raising the arm 42, said shoulder gives the breech-bolt and
extractor a very powerful start rearwardly, thereby starting the empty cartridge,
which sometimes, from the force of the shot, is slightly swelled out and has a
tendency to stick in the barrel.
The parts of the gun which ordinarily need cleaning, may be taken apart and put
together without tools of any kind whatsoever, in the following manner: Pull the
breech bolt back with the front end of the extractor sprung upward, so that its
projection 76, passes above the receiver; after thus removing the breech-bolt and
extractor the latter may be separated from the former by moving its tooth 73, along
and out of the groove 74, then moving it rearwardly out off the projection 67, of

page_text: the breech bolt; this will give access to the receiver; the cartridge cut-off may be
removed by raising its thumb piece 34, upward and pulling it out against the
frictional resistance of the spring hook 39-40. The part 11, 12, is simply to be
pulled downward, and the lid 16, may then be pushed out to the left; the cartridge
carrier may next be swung out of the notch 24, and dropped down from its stud 22.
The carrier spring being fastened as shown, may also be dropped from its place
when not held by the carrier; the pivots in the trigger and hammer may be pushed
out, as they are not screw-threaded, the trigger spring may be permanently fixed in
the rear end of the receiver, and the main or hammer spring, being held in the
manner shown, may be removed and re-inserted without tools; there is not a single
screw in the entire mechanism; the only three screws 98, 99 and 100, in the entire
gun are for securing the stock or woodwork to the iron. To assemble or put the
parts together the proceeding is exactly the reverse of that just described for taking
it apart.
From the above description it will be seen that a gun is provided which may be
fired very rapidly, and may have its magazine refilled in a moment, and its parts
made strong, durable, few and easy to take apart for cleaning, all of which points
are very important, especially in guns used by the army where sand and dust will
often be apt to get into the inechanism, requiring frequent removal and cleaning of
the working parts most exposed to such incidents, and that for such cleaning of
ordinary guns a box of tools is required and the many sinall parts and still smaller
screws, are very apt to get lost, all of which difficulties are overcome in this
invention.
The front locking notch 49, for the bolt lug 47, may extend to the top of the
receiver as in Fig. 10, and the stock need not necessarily extend underneath the
magazine, but may have a clearing there to admit of the removal of the bottom of
the magazine, if so desired, but usually the magazine will need no cleaning, so it is
mentioned more in order to show that even the magazine may be taken apart
without tools or removal of the stock, as a spring catch may hold its bottom and
permit it to be removed by applying suitable force or by pressing on a locking
spring.
