Improvements in Pistols.
I, AUGUST NYGREN, Farmer and Money Loaner, of Elizabeth, in the County of
Otter Tail, and State of Minnesota, United States of America, do hereby declare
the nature of my invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:
The object of my invention is to provide a pistol which may be carried about
the person with little danger of detection, and which may be held more steady
than the ordinary pistol when firing; and another object of the invention is to
construct a pistol which is particularly adapted for use by bicyclists, pedestrians,
and other persons having their garments fitted somewhat tightly to the body.
Another object of the invention is to construct a repeating pistol which will be
flat, and wherein two barrels will be provided, one being provided for the egress
of the ball, the other carrying the bolt mechanism, and to locate the trigger
between the two barrels. Another object of the invention is to provide a simple
and compact feed device, which will present a cartridge each time that the trigger
is pulled and released, thus preparing the barrel for a second discharge.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar characters of reference indicate corresponding parts
in all the figures.

.
Figure 7 is a section taken on the line 7-7 of Figure 4; and
Figure 8 is a section on the line 8-8 of Figure 6, showing the cartridge carrier
or block in dotted lines partly removed from the pistol.
The frame of the pistol consists of a grip or handle section A and two barrels B
and C, both barrels being in communication with a chamber 11 formed in the
One barrel is below the other, and the uppermost
grip or handle section A.
barrel sustains such relation to the top edge or body of the grip section that it
may be used for sighting purposes.

page_text: The chamber 11 is provided with a side rib 12 near each face of the handle or
grip section, and upon these ribs the cartridge carrier or cartridge block 13 is
fitted to slide. The back edge of the handle or gripping section is convexed, being
fitted to the palm of the hand, while a concaved surface 10 is formed at the front
of the handle below the firing barrel C, in order to accommodate a finger of the
hand grasping the handle.
•
The cartridge block or carrier 13 is shown in the drawings as provided with
three chambers, the intermediate chambers being separated by partitions 15, but
any desired number of chambers may be used. Each chamber is open at both
ends, but each chamber is shown as channelled at its rear or back end to receive
the flanges of the cartridges 16. A spring 17 is secured to the lower end of the
bottom wall of the chamber 11; which spring is preferably made up of series of
independent leaves, which extend transversely of the chamber, adjacent leaves
being alternately connected at their opposite ends. The inner end of the
spring 17 has an eye 17" formed thereon, receiving a projection or a stud 17b
from. the bottom of the cartridge block or carrier 13. The normal tendency of the
spring 17 is to draw the cartridge carrier or block in direction of the bottom of
the chamber 11 in which it has movement.
A cylinder 18, or what may be termed a cylindrical jacket, is fitted to slide in
the upper barrel B, and a trigger 19 is attached to the bottom side of the jacket 18,
the said trigger extending to the lower or firing barrel but being, however, inde-
pendent of the latter. The trigger is fitted to slide in an opening 20 made in the
under face of the upper barrel B, which opening extends from a point near the
centre of the barrel preferably to its inner end, and at the inner end of the upper
portion of the cylinder or jacket 18 a second longitudinal opening 21 is produced.
A firing bolt 22 is fitted to slide in the jacket 18, provided upon its under face
with a longitudinal slot 23, into which a pin 24 extends, secured to the trigger 19,
and serving in a measure to limit the movement of the firing bolt.
A spring 25
is attached to the front end of the firing bolt and to the front end portion of the
said jacket or cylinder 18, which front end portion has a flange 26 against which
the spring bears. A second spring 26 passes through the spiral spring 25, being
secured to the forward end of the firing bolt, and to a loop 27, or other form
of keeper, which extends across the front end of the barrel 3 in advance of the
jacket 18, even when the latter is in its extreme forward position, as illustrated in
Figure 3.
The outer and stronger spring 25 need not be actually attached to the
firing bolt, but may simply bear against the same.
A
A recess 28 is made in the upper portion of the firing bolt 22 near its rear end
or heel, the forward or front wall of the said recess being somewhat concaved.
pawl 29, is pivoted in the recess 28, and the head end of the pawl, which is
normally forced outward past the top of the holt by a spring 30, is normally in
engagement with a wall of a recess 31 made in the under face of the top end
portion of the grip or handle A. When the pawl 29 is thus in engagement with
the grip or handle section A it locks the firing bolt, and prevents it from being
forced backward, but at this time the jacket may be carried backward by exerting
tension in that direction on the trigger 19, compressing thereby the outer and
stronger spring 25 and placing the inner spring 26 under tension, as also shown
in Figure 4. When the trigger has been carried sufficiently backward, or nearly
to the grip or handle section A, the top rear edge portion of the jacket 18 will
have passed by the pawl 29, as shown in Figure 4, and forced the head of the pawl
out from its slot or keeper 31, whereupon the large or firing spring 25, which had
been compressed, will force the rear or striking end or heel of the firing bolt
violently in direction of the back of the grip or handle section, and across the
magazine chamber 11. When the firing bolt is thus carried rearward it strikes
the head 34 of the pivoted firing pin 32, rocking the said pin in such manner that
the firing point 35, which is at the opposite end of the firing pin, will be brought.
violently in engagement with the cap of the cartridge in the lowermost chamber
of the cartridge cylinder or block, as shown in Figure 4. The firing pin 32 is

page_text: pivoted at 33.in a recess at the back of the chamber 11 in which the cartridge
block slides.
After the firing bolt has made its impact on the firing pin, it and the jacket are
drawn back to their normal position by the lesser spring 26". A safety catch 36,
which is in the nature of an angular bolt is fulcrumed upon the front of the grip
or handle section, and when the firing bolt and jacket are in their normal position,
shown in Figure 3, by carrying one member of the safety catch through the slot 20
in the bottom of the upper barrel B and into a registering slot 20 made in the
bottom of the jacket (see Figure 3) the jacket can not be moved, and the weapon
may lie safely carried, since the trigger can not be drawn rearward to fire a
cartridge until the safety latch or catch is disengaged from the jacket. Even
when the safety latch is disengaged from the jacket the weapon may fall to the
ground, and even strike an object on the ground, without producing a movement
of the firing bolt, and consequently a cartridge at that time can not be exploded.
In order that the smoke and waste products of combustion may readily escape
from the pistol, slots 37 are made in the top of the grip or handle section, which
are in communication with the chamber 11.
'
The mechanism for controlling the feed of the cartridge carrier or block, after
it has been placed in position for the first fire, is as follows:
A cylindrical bolt 37 is fitted to slide in a suitable opening in the front portion
of the grip or handle section A, between the firing barrel and the barrel carrying the
firing bolt, nearer the former than the latter. The rear end of the bolt is inclined
forwardly from the top in direction of the bottom, and normally extends beyond
the rear edge of the front wall of the said handle, as shown particularly in
Figures 3 and 4. The bolt is provided with an opening 38 near its rear end, which
communicates with an interior chamber 39. The opening 40 in which the bolt
has movement, is increased in diameter at its forward end, in order to accommo-
At the forward end
date a spiral spring 41, which surrounds the aforesaid bolt.
of the bolt a cap 42 is placed, which cap carries a retarding member 43, located
within the chamber of the bolt, which said retarding member, when the cap 42 is
pressed, will extend beyond the rear end of the bolt 37, which may be termed a
locking bolt. The retarding member 43 is made to slide in the locking bolt
through the medium of a pin 44, which extends through an opening 45 made in
the locking bolt, as shown particularly in Figure 4. A small spring 46, has
bearing against a shoulder formed on the locking bolt, and is connected with, or
has bearing against the cap 42, as illustrated in Figure 5. A lug 47 is formed
upon the retarding member near its rear end, the upper face of the rear end of the
said retarding member being inclined from the lug to its rear extremity, as shown
in Figure 5, and the lug 47 on the retarding member is adapted in operation to
enter the recess 38 in the locking bolt. It is obvious that the retarding member
will have a rocking movement in the locking bolt.
When the trigger 19 has been pulled rearward a sufficient distance to effect an
explosion of the cartridge, the trigger will not have engaged with the cap 42
of the controlling device or mechanism for the cartridge chamber, and the locking
bolt, as shown in Figure 3, will be in engagement with an adjacent partition in
the cartridge block or carrier, holding the latter firmly in position. By a slight
further rearward movement of the trigger 19, said trigger will engage with the
cap 42, and will incline the retarding member 43, as shown in Figure 5, giving the
said retarding member an upward inclination to such an extent that its lug 47 will
enter the opening 38 in the locking bolt, while the rear end of the retarding member
will be brought in engagement with the partition formerly engaged by the locking
bolt when the trigger 19 is slightly released to relieve the cap 42, the spring 41*
at that time acting to force the retarding member forward, compelling the locking
bolt to travel in the same direction; therefore, the partition in the cartridge block
will be relieved from engagement with the locking bolt and will be engaged by
the retarding member.
This controlling mechanism having been entirely freed from engagement with

page_text: the trigger, the spring 17 will act to draw the cartridge carrier or bolt downward,
forcing the retarding member 43 out of engagement with the locking bolt, and
permitting the spring 46 to act to throw the locking bolt to its normal position,
so that the locking bolt will engage with the upper partition of the next chamber,
permitting the cartridge of the intermediate chamber to be brought into registry
or alignment with the firing barrel, so that at the next rearward movement of
the firing bolt the cartridge in the intermediate chamber of the cartridge block
will be exploded.
The forward ends of both of the barrels A and B are surrounded by a rein-
forcing band 48, and the forward end of the upper barrel B is closed by a plate 49,
or its equivalent.
When the cartridge carrier 13 is disconnected from its spring 17 and the cover
for the chamber 11 is removed, the cartridge carrier may be swung laterally out
from the chamber and loaded, as shown in dotted lines in Figure S.
