WILLIAM ROBERT LAKE of the Firm of Haseltine, Lake, & Co., Patent Agents
Southampton Buildings, London. "IMPROVEMENTS IN MAGAZINE FIRE-ARMS."
[A communication from abroad by William Trabue, of Louisville, Kentucky,
United States of America.]
This Invention consists chiefly First In an incline guide formed on the trigger
guard, for elevating the rear end of the cartridge as it leaves the magazine, cimployed
in connection with a stop notch formed on the inside of the receiver or frame of
the gun at the top against which notch the cartridge strikes and also in connection
with a finger or extension formed on the bottom and front of the bolt which finger
passes under and elevates the bullet end of the cartridge into alignment with the
bore of the gun when the bolt is forced forward: Secondly In a hammer provided
with an extension blade to prevent the turning of the same and the premature
discharge of the cartridge, on the bottom of which blade and near its forward end,
a notch is formed which, in connection with a similar notch formed on the Bear,
prevents the accidental withdrawal of the breech from the receiver or frame.
Thirdly. In a swinging extractor hook pinned or pivotted to the bolt head
diametrically opposite to its bite on the rim of the cartridge and provided with a
projection that strikes against the receiver when the bolt is withdrawn, in
connection with a cam cut on the bolt head, and Fourthly In a thumb screw acting
against the bolt for locking the breech.
These novel parts of a gun are so constructed and arranged in reference to the
parts which are common to other magazine fire-arms as to produce a gun very
simple, durable, and perfectly positive in its action.

page_text: A magazine fire-arm constructed according to this Invention has the following
parts, that is to say a receiver or frame in which a notch is formed; a bolt having
an extension; a hammer with an extension in which there is a notch; a sear
having a notch formed on the same; a sear spring; an inclined cartridge guide; an
extractor hook having a projection on the same; a cam cut on the end of a bolt
head; a pin or pivot on which the extractor hook swings; a projection on the side
of the receiver; a bolt locking-thumb screw; and a notch or indent on the bolt.
The above parts of a gun are constructed of the usual material.
In operating this gun the bolt is first retracted, then the cartridges are dropped
singly, bullet end forward down the incline guide and charged separately into the
magazine by means of the bolt. When the loading is completed the bolt is drawn
back and the magazine spring forces a cartridge up the incline guide until the rim
comes in contact with the notch in the receiver where it is retained, until, by the
forward movement of the bolt extension, it comes in contact with the cartridge
raising its bullet end into alignment with the bore of the gun. The further
forward movement of the bolt forces the cartridge into the barrel when the handlo
of the bolt is turned down and the gun is ready for firing. By turning down this
handle the extractor hook swinging on the pin, is acted upon by the cam and forced
over the rim of the cartridge in the barrel of the gun and the bolt is locked. As
the handle is turned back unlocking the bolt, the extractor hook by means of an
elevation on the cam is held firmly on the shell of the cartridge. On the retrograde
movement of the bolt the extractor hook draws the shell from the barrel and the
projection on the extractor coming in contact with the inside of the projections of
the receiver forces the shell rim into the notch and throws the shell from the barrel.
The extractor hook being pinned or pivoted diametrically opposite its bito on the
-rim-of-the-shell,-the-greater-the-resistance the stronger the hold. The notch in the
hummer extension or blado coming in contact with the notch in the soar provents
the breech leaving the receiver when the bolt is drawn back. The sear spring
holds the scar close to the underside of the hammer blade but the notch in the sear
is easily depressed below the notch on the hammer blade by pulling the trigger and
the breech may then be withdrawn from the receiver. Any suitable cut off may
be employed to keep the cartridges in the magazine while loading or when the gun
is being used as an ordinary breech-loader.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN MAGAZINE FIRE-ARMS.'
A communication from abroad by William Trabue, of Louisville, Kentucky,
United States of America.
This Invention consists chiefly :-First, In an inclined guide formed on the trigger
guard for elevating the rear end of the cartridge as it leaves the magazine, employed
in connection with a stop notch formed on the inside of the receiver or frame of
the gun at the top, against which notch the cartridge strikes, and also in connection
with a finger or extension formed on the bottom and front of the bolt, which
finger passes under and elevates the bullet end of the cartridge into alignment with
the bore of the gun when the bolt is forced forward:-Second, in a hammer pro-
vided with an extension blade to prevent the turning of the same and the premature
discharge of the cartridge, on the bottom of which blade, and near its forward end,
a notch is formed which in connection with a similar notch formed on the scar,
prevents the accidental withdrawal of the breech from the receiver or frame.
Third, In a swinging extractor hook pinned or pivotted to the bolt head
diametrically opposite to its bite on the rim of the cartridge and provided with a
projection that strikes against the receiver when the bolt is withdrawn, in con-
nection with a cam cut on the bolt head, and Fourth, In a thumb screw acting
against the bolt for locking the breech.
These novel parts of a gun are so constructed and arranged in reference to the
parts which are common to other magazine fire-arms, as to produce a gun very
simple, durable and perfectly positive in its action.
"
In the accompanying Drawing, which clearly show all of the said improvements,
Figure 1 is a vertical longitudinal section.
Figure 2 is a broken top view of the receiver.
Figures 3 and 3 show the extractor hook in different positions.
Figures 4 and 4 show the bolt locking device, and,
Figure 5 is a view of the notched hammer with its extension blade and a portion
of the notched sear.
A designates the receiver or frame, and c a notch formed in the same; B the
bolt and C the extension of the same; E the hammer; F its extension; and a a
notch formed on the same; G the sear and b a notch formed on the same; H the
sear-spring; I the inclined cartridge guide; J the extractor hook, and d a pro-
jection on the same; L the cam cut on the end of the bolt head O; M the top of
said cam.
N the pin or pivot on which the extractor hook swings; Q a pro-
jection on the side of the receiver; R the bolt locking the thumb screw and S a
notch or indent in the bolt.
The above parts of a gun are constructed of the usual material and their
configuration is clearly shewn in the Drawing.
In operating this gun the bolt B is first retracted as shewn in Figure 1, then the
cartridges are dropped singly, bullet end forward, down the inclined guide I and
charged separately into the magazine by means of the bolt. When the loading is
completed, the bolt B is drawn back and the magazine spring forces a cartridge up
the inclined guide until the rim comes in contact with the notch c in the receiver
where it is retained until, by the forward movement of the bolt, the extension C
coines in contact with the cartridge raising its bullet end into alignment with the

page_text: bore of the gun. The further forward movement of the bolt forces the cartridge
into the barrel, when the handle of the bolt is turned down and the gun is ready
for firing. By turning down this handle the extractor hook swinging on the pin N
is acted upon by the cam L, Figures 3 and 3, and forced over the rim of the
cartridge in the barrel of the gun and the bolt is locked. As the handle is turned
back unlocking the bolt, the extractor hook by means of the elevation M on the
cam L, is held firmly on the shell of the cartridge. On the retrograde movement
of the bolt, the extractor hook J draws the shell from the barrel and the pro-
jection d on the extractor, coming in contact with the inside of the projections Q of
the receiver forces the shell rim into the notch c as shewn in Figure and throws
the shell from the barrel. The extractor hook being pinned or pivotted
diametrically opposite its bite on the rim of the shell as shewn in the Drawing, the
greater the resistance the stronger the hold. The notch a coming in contact with
the notch b, clearly shewn in Figure 5, prevents the breech leaving the receiver
when the bolt is drawn back. The spring H holds the sear G close to the undersido
of the hammer blade F, but the notch in the sear is easily depressed below the
notch in the hammer blade by pulling the trigger, and the breech may then be
withdrawn from the receiver. The locking device for screwing the breech in the
receiver or frame is clearly shewn in Figures 4, 4, and need not be further
described. Any suitable cut off may be employed to keep the cartridges in the
inagazine while loading or when the gun is being used, as an ordinary brecch
loader.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same I wish it understood
that I claim,-

Third. The notched blade F, in combination with the notched sear G, for the
purpose specified.
Fourth. The extractor hook J constructed and pivotted as described, in com-
