page_text: COMPLETE SPECIFICATION.
We JOSEPH DESREIAUSSEAUX LUCAS, Real Estate Agent, and WILLIAM JOHN
KRIZ, Harness Maker, both of the City of Saint Louis, in the State of Missouri,
one of the United States of North America do hereby declare the nature of the
said Invention for IMPROVEMENTS IN FIRE ARMS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The following is a full, clear and exact description of our invention, reference
being had to the accompanying drawings in which: Figures 1 and 14 are side
views, Figure 1 showing a hammerless gun, Figure 2 is a breech end view of the
barrels.
Figures 3 and 4 are enlarged detail sections of the breech ends of the barrels
taken on line 3-4 Figure 2.
'
Figures 5 and 6 are vertical sections taken on lines 5, 5, and 6, 6, respectively,
Figure 8.
Figure 7 is a detail top view of part of the stock and barrels.
Figure 8 is a section taken on line 8, 8 Figure 5.
Figures 9, 10, 15 and 16 are detail views.
Figure 12 is a transverse section of the barrels taken on line 12-12 Figure 1.
Figure 13 illustrates a modification.
:
Our invention relates principally to improvements for which Letters Patent
N° 1215 dated March 7th 1883 were granted to G. Macaulay-Cruikshank, and our
invention consists in locating the rifle barrels between the shot barrels, when the
barrels are composed of separate pieces of metal as distinguished from one piece as
in said patent.
Our invention further relates to certain matters of detail as to the construction
of the gun, as fully described hereafter and pointed out in the claims.
Referring to the drawings, A represents the stock, B the shot barrels and C the
rifle barrels of the gun. The rifle barrels are located between the shot barrels
(there being two of the rifle, and two of the shot barrels) and are made of separate
pieces of metal as shown in figure 12 brazed together and to the shot barrels, or the
two rifle barrels may be made of one piece of metal, grooved out to receive the
shot barrels, as shown in figure 13, but we prefer to make them in two parts.
Barrels thus made are or can be made much lighter in weight than when made
in one piece of metal as in the patent above mentioned and have every advantage
of being compact and of having the four bores in proper position for the gun to
shoot accurately whichever barrel or bore is used.

page_text: We are of course aware that two shot barrels and one rifle barrel have been united
in a single gun with the rifle barrel beneath and of a separate piece of metal from
the shot barrels, but we believe it to be of our invention to locate between two
shot barrels, two rifle barrels when they are made of different pieces of metal.
The barrels are secured to the stock in the ordinary way and are held in firing
position by a sliding bolt or bar D that engages with the lugs I on the bottom of
the barrels and is operated by a cam J on the lower end of a vertical rock shaft
or pin J to the upper end of which is secured a thumb lever J2 for turning it. The
cam is three sided as shown in Figures 9 and 10 and when it is moved by the lever
from the position shown in Figure 9 to that shown in Figure 10 the bolt D is forced
back to unlock the barrels, and when the cam, by the lever, is moved back from
the position shown in Figure 10 to that shown in Figure 9 the spring W acts to
return the bolt or bar D to its locking position.
The shape of the cam prevents the lever from being moved but in the one
direction.
L represents the exrtactor of the two shot barrels and the upper rifle barrel
which is operated in the usual way, and L¹ is the extractor of the lower rifle barrel,
which is a pin fitting in a socket L² of the barrels and having a head L³ to engage
the rim of the shell, see Figures 3 and 4 and behind the spring in the socket, is a
spiral spring L to force the pin out and extract the cartridge.
N represents the hammers which in figure 14 are on the outside of the locks, and
in figures 1, 5, 6 and 8 are on the inside of the locks.
In figure 14 a sliding block N' is dovetailed into the hammer of each lock and
by moving it up or down it is made to strike either of its firing pins P which are
arranged as in the aforesaid patent.
In figures 1, 5, 6 and 8 the blocks are dovetailed into the hammer and connected
to their lower ends are small bell crank levers O that are pivotted to the lower
ends of the stock at 02 and to the hammers by pins O³ fitting in slots O' in the
levers, see figure 6.
The ends of the levers that are not connected to the sliding blocks are roughened
and adapted to be pressed upon by the finger to move the blocks up or down to
cause them to strike the desired pin P.
Either of these hammers or both of them can be held cocked by sliding plates T
having shanks T with heads T2 on their upper ends, the shanks fitting side by
side in a slot U in the stock. The plates can be moved independently of each other
so that either or both of the hammers can be held cocked, and they are held to
their adjustments by springs V engaging in notches in the stock; see Figures 5
and 6.
The bolt or bar D in addition to securing the barrels in firing position, also
serves to cock the hammers (in the hammerless gun) by coming against them, as
shown in figure 6 when it is retracted.
A spring W, secured to the stock and pressing against the bolt or bar D acts to
return the bolt or bar after it is pulled back by the lever J²,
Y represents a piece of the stock held in place by a conical pointed bolt Y' (see
figure 11) fitting in a hole in a lug X' on the barrel and having a spring Y³
behind it.
The piece Y is notched to receive the lug Y2 and has a recess to receive the
conical end of the bolt as shown. This bolt thus holds this piece Y to the barrels
but allows its easy removal by simply pulling its outer end down or away from
the barrel when it is desired to disconnect the barrel from the stock,
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. A compound gun having two shot barrels and two rifle barrels made of
different pieces of metal, the rifle barrels being located directly between the shot
barrels of set forth

page_text: 2. In a compound gun, the two shot barrels and two rifle barrels made of
different pieces of metal, and the rifle barrels located between the shot barrels, in
combination with two extractors, substantially as and for the purpose set forth.
3. In a compound gun, the two shot barrels and two rifle barrels, made of
different pieces of metal, and the rifle barrels located between the shot barrels, in
combination with the hammers and locking and cocking pin D operated by a cam,
rock shaft and lever, substantially as set forth.
4. In a compound gun the two shot barrels and two rifle barrels, made of
different pieces of metal, and the rifle barrels located between the shot barrels, in
combination with the hammers, and the two moveable plates T working side by
side in a slot in the stock for holding the hammers cocked and held to their
adjustment by springs V as set forth.
5. In a fire arm a hollow or dovetailed hammer and block N adapted to slide in
the hammer, in combination with upper and lower firing pins, the said block being
adapted to strike a firing pin in either its upper or lower position as set forth.
6. In a fire arm, the combination of a hammer an adjustable block on the
hammer, a lever hinged to the stock and connected to the block, the block being
adjusted by said lever to place it in position to strike either firing pin as set forth.
7. In a fire arm the combination of the piece Y with a recess and a notch, and
the barrel having a recessed lug to receive a spring bolt having a conical point, the
lug adapted to fit in a recess in the piece Y and the conical point of the bolt adapted
to fit in the notch in the piece, substantially as set forth.
