I, William Robert LAKE, of the firm of Haseltine Lake, and Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 following statement:
-
This Invention relates to an improvement in that class of fire-arms in which the
breech-piece is a part of a sliding-bolt provided with a handle extending radially
therefrom, and by which the breech-piece is drawn backward in opening, or forced
forward in closing, and in which the breech-piece is secured by imparting to the bolt
a rotation by means of the said handle, and particularly to those arins of this class in
which a case containing cartridges may be applied over an opening in the receiver,
so that cartridges will successively fall in front of the breech-piece when in its rear or
open position, and be forced into the cartridge chamber by the forward movement of
the breech-piece.
The magazine is in length substantially that of the length of the cartridges to be
employed, and is constructed with partitions to form a circuitous pocket in which
several cartridges side by side, or parallel with each other, may be introduced and
arranged upon the barrel with the opening downward, so that as one cartridge passes
from the mouth of the magazine into the receiver, others in the column follow by
their own gravity, presenting successive cartridges to the opening in the receiver as
the lowest one is transferred to the barrel.

page_text: The object of the first part of the Invention is to provide a separating device
between the column of cartridges and the receiver, so that it is impossible for a
cartridge from the magazine to pass into the receiver unless the receiver is clear, or
a previously introduced cartridge has been entirely removed, whereby choking of the
passage is impossible.
The object of the second part of the invention is to make a dead-lock for the
magazine when in place, and while the breech-piece is in its closed or firing position,
so that by such lock, not only is the magazine surely brought to its position to deliver
a cartridge to the receiver, but so securely held that displacement is impossible from
the act of firing.
The object of the third part of the Invention is to make the engagement between
the extractor and the head of the cartridge in the barrel positive, so that escape after
engagement is impossible until they are completely withdrawn.
The object of the fourth part of the Invention is to make an interlock between the
breech-piece and the receiver independent of the handle, whereby the cam action for
the final closing of the breech piece and the first part of the opening movement for
starting the cartridge may be produced in the receiver independent of the handle,
shoulder, or lug.
The object of the fifth part of the fnvention is to provide a locking device which
will prevent the accidental withdrawal of the breech-piece entirely from the receiver,
and which locking device may be operated by an over-motion of the trigger, so that,
if the trigger be pulled sufficiently far backward, the breech-piece may be removed,
but not otherwise.

A represents the receiver, to the forward end of which the barrel B is secured, in
the usual manner. Crepresents the breech-piece, which is arranged to slide longitu-
dinally in the receiver, the bolt of which is provided with a handle D by which the
breech-piece may be rotated, and which handle works into or from a recess E in the
side of the receiver, so that when the breech-piece is in the closed position, the handle
is turned down into the recess E. and the breech-piece locked, or when the handle is
raised from the recess, and brought into a vertical position, the breech-piece may be
drawn rearward for opening, the handle passing through a groove in the top of the
receiver to the open position, as seen in Figure 2; this being a common construction
of arms, does not require particular description.

page_text: Upon one side of the receiver is a projection F, which forms an enlargement of
the cartridge receiving chamber, see Figures 1. 2, and 3. To the top of this enlarge-
ment of the cartridge chamber, the magazine G is attached, as seen in Figures 3, 4,
and 5, the magazine being in the form of a case, adapted to receive several cartridges
parallel with each other, and so that when in place, the cartridges may roll by their
own weight downward to the mouth of the magazine, and the mouth of the magazine
being directly over the enlargement of the receiving chamber in the receiver, will
conduct the cartridges into their proper position in the receiver, forward of the front
face of the open breech-piece.
The opening or mouth of the magazine is of a shape to permit the cartridge to fall
through it into the receiver, but it is necessary that the column should be supported
independent of the cartridge in the receiver, or of the breech-piece, so that the
breech-piece may be moved backward and forward. To this end a separator II is
arranged in the receiver, at the forward end of the receiving opening, hung upon a
pivot in the receiver opposite the magazine side, and so as to swing backward and
forward in a horizontal plane, as from the position seen in Figure 1, to that seen in
Figure 2. When standing in the position seen in Figure 1, the passage into the
receiver is fully open, but when the separator H is turned rearward as seen in
Figure 2, it extends into the opening, and immediately below the mouth of the
magazine, and so that the forward end of the lowest cartridge in the magazine will
rest on the separator, as indicated in Figure 2. At the rear end of the opening in
the receiver is a second separator I, hung in the receiver upon a pivot b, and so as to
swing in a horizontal plane, and in substantially the same plane as the separator H,
but so that when turned backward as seen in Figure 1, the opening into the receiver
is free, but when turned forward, as seen in Figure 2, then the separator I extents
into the opening below the lowest cartridge, and so as to support the rear end of that
cartridge. The magazine mouth is only of a size to permit the free movement of a
cartridge therefrom into the opening in the receiver, as seen in Figure 3.
The separators are operated by the breech-piece, the forward separator His con-
structed with a rearward and inward projection d from its hub end, which extends
into a recess e in the side of the breech-piece, as seen in Figure 1, when the
breech-piece is in the closed position, the breech-piece also bears against the rear
side of the separator H, so as to hold the separator in the forward position, when
the breech-piece is closed, and as seen in Figure 1, but upon the first part of the rear
movement of the breech-piece, the forward end of the recess e bears against the
projection d from the hub of the separator, and acts as a cam thereon to turn the
separator rearward into the position seen in Figure 2, so that one cartridge having
passed from the magazine into the receiver, and alongside the breech-piece, the
separator H will pass above such cartridge in the receiver, and immediately below
the forward end of the next cartridge in the magazine, then as the breech-piece
continues its rear movement, a shoulder in the side of the breech-piece engages a
corresponding shoulder on the hub of the separator I, and as the breech-piece
continues its movement, the shoulder facts as a cam upon the separator I, and turns
it forward over the rear end of the cartridge in the receiver, and below the next above
in the magazine, as seen in Figure 3, so that the two separators hold the column
of cartridges in the magazine suspended. As the breech-piece reaches its extreme
rear position, the cartridge in the receiver then rolls into its place forward of the
front face of the breech-piece, as indicated in broken lines Figure 2 so that when
the breech-piece is again moved forward, the cartridge will be forced into its
place in the barrel, in the usual manner for this class of arms; the column of
cartridges in the magazine will be held suspended until as the breech-piece approaches
its closed position, it strikes the rear face of the separator H, and forces it forward
into its closed position, as seen in Figuro 1, and so as to leave the forward end
of the first cartridge in the magazine free to drop into the receiver, and as the
breech-piece approaches its closed position, a second shoulder on the breech-piece
strikes a corresponding shoulder on the hub of the separator I, and as the
breech-piece completes its closing movement, turns the separator I, rearward into

page_text: its closed position, as seen in Figure 1, and so as to permit the rear end of the
said next cartridge in the magazine to drop, that is to say, when the breech-
pieco is in its closed position, the mouth of the magazine is open, but immediately
as the breech-piece commences its rear movement, the separator H is thrown
outward, and so as to come below the next cartridge in the magazine, and separate
the column from the cartridge which may have passed into the receiver, and also
turns the rear separator into a like position, so that the column of cartridges in the
magazine is supported while the breech-piece is open, and until on its return it reaches
its closed position.
As the breech-piece reaches its closed position, the extractor engages the head of
the cartridge which it has forced into the barrel, and so that when next the breech-
piece is withdrawn, the shell (or cartridge if it be not exploded,) will be with-
drawn accordingly, and pass rearward beside the cartridge which then lies in the
receiving chamber, and until the breech-piece has arrived at its extreme open
position, when the shell will drop from its engagement with the extractor through
an opening in the under side of the receiver, leaving the way open for the cartridge
which has fallen into the receiver from the magazine to come into place forward of
the front face of the breech-piece, and in its turn be forced into its place in the
barrel.
The shoulders which operate the separators are formed in the sides of that part of
the breech-piece which extends above the bolt, and which moves backward and forward
through the opening in the top of the receiver. The shoulders and which operate
the rear separator I, are seen in Figure 7. They are in line with the respective
shoulders, on the separator I, the shoulder above the shoulder f; from the
shoulder fa groove / extends, rearward and from the shoulder a groove m extends
forward, the two grooves forming a single groove between the two shoulders, so that
the paths of the shoulders are one above the other. The shoulders, i on the separator I
are correspondingly arranged, as seen in Figure E.
As it is impossible that the separators can be thrown from their position supporting
the column of cartridges until the breech-piece is completely closed, and so that its
extractor shall have positively engaged the head of the shell or cartridge in the barrel
which it has forced therein, it follows that a second cartridge cannot escape from the
magazine into the receiver until the breech-piece has been so fully closed as to make
engagement with the cartridge in the barrel, in doing which the separators are with-
drawn from their support of the column, and the lowest cartridge of the column will
fall into the receiver beside the breech-piece, and before the cartridge so falling can
have passed to its position forward of the front face of the breech-piece. The separators
are positively introduced above the lowest cartridge, and below the column, so as to
support the remaining column until this second cartridge shall have been forced into
the barrel and positively withdrawn therefrom.
The magazine G is constructed with a flange n projecting from its forward end,
which is adapted to pass beneath a transverse groove on the receiver. The edge of
the flange and the groove are of correspondingly curved shape, as indicated in broken
lines Figure 4, so that the flange n on the front end of the magazine is first
introduced beneath into its groove which serves as a centre upon which the
magazine may turn, then a similar flanges on the rear end of the magazine passes
into a corresponding groove on the receiver at the rear end of the opening into the
receiver.
When the magazine is in proper place, its mouth stands over the opening into the
receiver, and in proper relative position thereto, so that the cartridges may fall from
the magazine into the receiver, as before described.
Owing to the interlocking character of the flange and groove at the forward end,
that end is held firmly to support the rear end a spring bolt is introduced, see
Figure 4, which acts as a latch to engage the magazine when in its proper position,
but as this latch must present an inclined nose so that the magazine may be removed
or inserted without mechanically moving the latch, the force of the recoil frequently
tends to overcome the power of the latch, and throw the rear end of the magazino

page_text: outward, as seen in Figure 4, thus loosening it from its latch, and rendering it liable to
complete accidental displacement.
To insure the retention of the magazine in its proper position, its lower edge is
constructed with an inclined notch at its rear end, and on the breech-piece a
corresponding hook y is formed or applied, see Figure 1. In Figure 4 the magazine is
represented with its rear end slightly withdrawn from its proper position, but in such
position the notch w stands in the path of the hook y on the breech-piece as the breech-
piece approaches its closed position, and as the breech-piece completes its closing
movement, the hook y engages the notch interlocks therewith, and draws
the magazine to place, as indicated in Figure 5, so that when the breech-piece
is closed, the magazine is positively locked in its proper position for delivering
cartridges, and so that the recoil can have no effect to displace it, but as the
breech-piece commences its opening movement, which is produced by the turning
of the handle in the usual manner, and as hereinafter described, the hook y, withdraws
from its engagement with the magazine, and leaves the magazine free to be removed
or replaced as occasion may require, or to remain in its place, if sufficiently charged,
until the breech-piece is again returned to its closed position, when the magazine will
be relocked by the hook y. With this engagement there is no liability of accidentally
displacing the magazine in the use of the arm, so long at least as the breech-piece
remains in its closed position.
y.
It will be evident that it is desirable in the use of this class of arms that the extractor
should make positive engagement with the head of the cartridge, in contradistinction
to simply a spring engagement, which is liable to escape from the cartridge, if the
cartridge offers sufficient resistance therefor. To accomplish this desirable object, the
extractor is constructed in the form of a V shaped spring N representing one leg of
the spring, and M the other. The extractor is introduced into a longitudinal chamber.
in the breech-piece, see Figure 9. Preferably at its rear end the extractor is provided
with a stud O, which rests in an elongated recess P in its chamber, so that while it
prevents the extractor from being withdrawn from its chamber, it permits a certain
amount of longitudinal play for the extractor.
The leg M takes a bearing or seat in the forward end of the extractor chamber,
but so as to leave the leg otherwise free to act as a part of the spring for the extractor.
The leg N is constructed at its outer end with the usual bevel-nosed hook R, adapted
to ride over the flange of the cartridge as the breech-piece approaches its closed
position, its elasticity permitting it to yield in so doing, but so as to drop over the
Hange of the cartridge when the chamber is fully closed. As the extractor stands in
its rear position, as seen in Figure 9, the extractor is free to rise to thus ride over
the head of the cartridge. The extractor leg N is constructed upon its under side
with a downward and forwardly inclined or hook shaped shoulder S, and the bottoin
of the extractor chamber is constructed with a correspondingly inclined hook shaped
shoulder T. The longitudinal movement of the extractor is sufficient to permit its
hook shaped shoulder S to engage with the corresponding shoulder T in the breech-
piece as indicated in broken lines.
If after the extractor has made its engagement with the cartridge, the breech-piece
be withdrawn, and the cartridge offers any considerable resistance to leaving its place
in the barrel, the extractor will be held by the cartridge while the breech-piece will
move rearward until the shoulder T has interlocked with the shoulder $ on the
extractor, then because such engagement of the extractor with the breech-piece
prevents the extractor rising, it cannot escape from the head of the cartridge,
consequently the cartridge must follow the breech-piece if the breech-piece continues
its rear movement. After the cartridge has been fully withdrawn, and escaped from
the receiver as before described, in the next advance of the breech piece the nose of
the extractor will strike the next cartridge under the force applied to the breech piece,
and the extractor will be moved rearward out of its locked position, and so that at the
proper time, it will be free to rise and pass over the flange of the cartridge, as before
described.
In the usual construction of this class of arms, the handle acts as a cam against the

page_text: rear edge of the recess in the receiver, into which it turns in locking the breech-piece,
and so that the handle itself is the block to resist recoil. The handle D, as before
described, is made substantially a part of the bolt U, the bolt being tubular, and of
the usual construction to contain the hammer and main-spring, as shown. Upon the
bolt diametrically opposite the handle, is a radially projecting lug V, see Figures 7
and 9. In the receiver in the bottom of the recess through which the bolt travels
in opening and closing the breech-piece, is a longitudinal groove W, sec Figures 6
and 10, in which the lug V moves in the backward and forward movement of the
breech-piece. At the closing position of the breech-piece, the groove W is turned to
one side and upward, to form a right-angular extension Y of the groove, see
Figures 6 and 10. The width of this extension of the groove Y corresponds to the
length of the lug V upon the underside of the boit. The turn from the groove W
into the extension Y is made of a cam shape, as seen at 3 Figure 10, against which
the rear end of the lug V will work as the handle is turned to the locking position
and so that the lug V working over this cam shaped entrance to the extension Y of
the groove, will operate to force the breech-piece forward to its completely closed
position, and so that the lug V with the extension Y of the groove, will serve to resist
the recoil; then in the opening movement of the handle, the lug V will work against
the cam shaped forward end 4 of the groove W, and impart to the breech-piece the
first part of what is called its starting movement. This relieves the handle and the
rear end of its recess in the receiver from the great wear which is brought upon it in
the usual construction.
To prevent the possibility of discharge of the hammer, until the breech pieco is
substantially locked, the hammer 5 is constructed with a forwardly projecting arın 6
upon its underside, see Figure 9, which extends along the under surface of the bolt,
and from the arm 6 is an upward projection 7, which extends into a groove 8 in the
underside of the bolt, when the bolt is in the locked position, and as seen in Figure 12.
This groove 8 is longitudinal, and so that the bolt may be drawn to full cock, or
permitted to be discharged, the projection 7 working longitudinally through the
groove 8 in such movement. In the bolt is a second groove 9 parallel with the
groove 8, and distant therefrom corresponding to the rotation of the bolt in opening,
and so that when the bolt is turned to the position for opening the breech-piece, the
said groove 9 will stand in line with the projection 7 on the arm 6 of the hammer,
and as seen in Figure 11. These grooves at their forward end are connected by a
circumferential groove 10, and at their rear end are connected by a like circumferential
groove 11.
When the hammer is in the closed position, and the bolt is turned to the
locked position, the projection 7 on the arm 6 stands at the forward end of the
groove 8, as seen in Figure 12, and in line with the circumferential groove 10. If
now the bolt be turned to the unlocked position, it will bring the second groove 9
into line with the projection 7 on the hammer, then as tho bolt with the breech-
piece is forced backward, in the usual manner, the hammer will also be forced
backward, but on the return, as the hammer comes to the cocked position, it engages
the sear, and will be thereby stopped while the bolt and breech-piece will move forward,
and in such a forward movement, the groove 9 will pass over the projection 7 from
the arm 6 of the hammer, until the closing position is reached, as seen in Figure 11,
then the hammer being so held, the bolt is turned toward the locked position, the
said projection 7 then passes into the rear circumferential groove 11, and will stand
there until the bolt is completely locked, and so as to bring the groove again
into line with the stud 7 on the arm 6. Now if at any time during the locking
movement of the bolt the trigger should be pulled, the forward side of the groove 11,
as seen in Figure 13, will arrest the hammer, and prevent its escape, and will so
hold it until the bolt is brought to the completely locked position, as seen in
Figure 12, and so that the groove & will come into line with the projection 7 on
the hammer arm 6, thus it is impossible to discharge the hammer until the breech-
piece is completely locked in the closed position.
To prevent the accidental withdrawal of the bolt and breech-piece, and yet permit
its easy withdrawal when occasion requires, a dog 12 is arranged, see Figure 15,

page_text: in the receiver beneath the bolt, hung upon a pivot 13, and extending forward
therefrom, adapted to engage a notch 14 in the breech-piece when the breech-piece
is at its extreme rear position. This dog is arranged forward of the sear 16, the
sear being hung upon a pivot 17, and so as to be actuated by the trigger 18 to engage
the cock notches of the hammer, in the usual manner.
From the hub of the sear a finger 19 extends forward, and from the dog 12 a
finger 20 extends rearward and over the finger 19, and between the dog and sear a
spring 21 is introduced, to bear upon both, the tendency of which is to force both
the scar and the dog forward toward the hammer or breech-piece. The sear is free
to operate under the action of the trigger, in the usual manner. If the breech-
piece be drawn rearward while the trigger is free, the notch 14 will engage the
dog 12, as indicated in broken lines Figure 15, and so as to prevent. further
withdrawal after such engagement is made, but if the trigger be pulled sufficiently
far, the finger 19 of the sear will be turned up against the finger 20 of the dog 12,
and so as to turn the dog downward, and hold it out of possible engagement with the
notch 14, then the way is clear for the complete withdrawal of the breech-piece. This
arrangement whereby under the action of the trigger the removal of the breech-piece
is permitted, is a great convenience.
The single spring 21 is preferred as a means for actuating both the sear and the dog,
but an independent spring may be introduced for the dog if desired, say as indicated
in broken lines Figure 15, and the sear provided with its usual spring, as also
indicated in broken lines.
Parts of the Invention described, it will be evident are applicable to single loaders.
Instead of making the inward swinging movement of the separators, positive, as
described, the inward movement may be produced by a spring, indicated in broken
lines Figure 2, the withdrawal or opening movement being positively produced, or
the springs may be employed together with the positive means.
It may
be desirable to construct the arm so that while the magazine remains
charged, the cartridges may be introduced into the arm leaving those in the magazine
in reserve.
As the arm is represented the magazine is upon the left hand side, the
opening in the receiver through which the cartridges pass is not of sufficient extent
to permit the cartridges to be introduced at the right of the magazine, while the
magazine is in place, but this opening at the right of the magazine may be increased
by cutting away the receiver, as indicated by broken lines Figures 1, 2, 3, and 4, to
a sufficient extent to permit cartridges to be introduced singly into a position forward
of the front face of the breech-piece while the magazine is in place.
