Improvements in the Manufacture or Production of Metallic Cart-
ridge Cases or Shells and in Appliances and Machinery to be
Employed therefor.
We, GEORGE KYNOCH of Lion Works Witton near Birmingham in the County of
Warwick, Manufacturer and JOSHUA CLARK of Witton Road Aston Manor near
Birmingham aforesaid Engineer do hereby declare the nature of our said invention
for "IMPROVEMENTS IN THE MANUFACTURE OR PRODUCTION OF METALLIC CARTRIDGE
CASES OR SHELLS, AND IN APPLIANCES AND MACHINERY TO BE EMPLOYED THEREFOR
to be as follows:-
""
Our invention relates to the manufacture or production of metallic cartridge cases
or shells, principally for machine guns and cannon, by the combination of processes
and appliances and machinery hereinafter described.
Our invention consists 1st in the formation or production of the blank, which is in
the form of a cast cup or ferrule, with closed bottom, and from which a cartridge case
or shell is subsequently made. 2nd, in the process of boring the inside of the said
cast cup, true, for the subsequent operations of stretching and drawing, and in
appliances and tools to be employed therefor.
3rd, in stretching or extending longitudinally, or in an upward direction the walls
of the shell, by removing a portion of the metal from the thickened base by a process
of displacement. 4th, in machinery to be employed in the drawing and finishing
processes.
In carrying out our improvements, we will describe them in counection with a
metallic cartridge case for a machine gun.
The metal blank or cup is produced by the process of casting, by employing a
metal mould made in segments or halves, and secured together by rings or snugs and
pins. The inside of the mould is of the size as the outside of the blank to be made;
and within the inside of the said mould, a hanging or depending metal core is dis-
posed, having an axial hole through its middle, and inclined vent holes through its
sides leading to its middle; and through which vent holes, enclosed air, or gaseon:

page_text: products given off from the fused metal, pass away in the process of casting, so as to
prevent blow-holes or honey-combing of the metal.
The internal hanging metallic core is connected to the underside of a plate, accurately
fitting within a recess on the top of the sides of the mould; so that on the said plate
which has vent holes in it and parts attached to it, being dropped into position, the
core becomes perfectly central. Suitable gets are arranged for the introduction or
passage of the metal into the mould.
The blank, cup or solid ended cylinder thus produced, is now bored or drilled to
the depth and diameter required, and the outside diameter skinned over by ordinary
cutting or shaping tools, so as to make the outside true to the inside.
The process of boring is conducted by machinery consisting of an arrangement of
parts similar in construction to an upright drill, provided with a self-acting feed, and
a table at right angles thereto.
Thus the machine consists essentially of a joggling carrier consisting of a movable
bed, having snugs or uprights at two opposite points, against which cross arms carried
by a holding bush is joggled or partially rotated, in order to change or vary the
position of the blank being operated upon with respect to the drilling and boring
appliance.
The holding bush consists essentially of a thick cylinder of the external diameter
of the size of a cartridge case or blank to be operated upon, and which said cylinder
is open at top and bottom, with the latter resting upon the top of the carrier bed,
which is supported thereunder, by the table or rest of the machine; and extending
from the two opposite sides of the lower end of the said bush are carrying arins,
which are presented to the back and front of the snugs or uprights carried by the
joggling carrier.
This carrier bush is fitted with two or more set pins near its base, so as to form
holding clams to the blank, in order to prevent it moving or turning round, other than
with the holder by which it is carried.
To completely fulfil this operation, other like machines will be required to perform
subsequent operations in completing the inside.
The next operation is the process of displacing a portion of the metal from the base
and sides, and causing it to flow upwards, and increase or lengthen out, the walls of
the shell; this is performed or accomplished in a similar appliance to that last
described for boring, and consists of a central mandril or roller forced. vertically
towards the bottom and sides of the partially prepared shell or blank, and which said
blank is at the same time joggled as by the aforesaid mechanical appliance or
appliances.
The combined constant pressure exerted by the mandril or roller upon the inside of
the partially formed blank, on the former being fed forward, and the latter joggled,
causes the inetal to be displaced, and the part where pressure is applied, and from
thence caused to flow upwards and stretch out the walls of the case. This last named
process or processes of displacement or elongation has the effect of hardening and
stiffening the walls and sides of the shell, leaving the metal of the base soft.
The turning and trueing of the outside with the inside may be carried out by means
commonly known.
This partially formed cartridge shell is further completed by a drawing or rolling
process or processes, consisting essentially of machinery arranged to work to and fro,
instead of only in a forward direction as heretofore.
The parts consist of a traversing cross head or heads worked by twin screws (right
and left handed) each situated at the outside ends of the cross-head, and with the
punch holders disposed centrally, and parallel to each other, and in the same plane and
direction as the screws.
The bed consists of a longitudinal frame supported upon legs or rests, and with
suitable bracket bearings for carrying the cross head, screws and other parts; and
which said screws are provided at each of their ends with driving toothed wheels,
which gear with pinions mounted upon a shaft carrying four pulleys, two loose and
two fixed, and through which said train of wheels and pulleys, an alternating traversing

page_text: motion is given to the cross head carrying the punch holders; and which said holders
are so arranged, that a cartridge shell is being operated upon, on the forward motion,
as well as by the backward motion.
The framing or bed has side troughs partially surrounding the screws, and
wherein a suitable lubricant is placed, and which said screws pass through screw boxes
in the cross heads, and which cross heads traverse in suitable guides made in the
framing.
Instead of employing a hollow blank ferrule or cup, a solid cylinder may be
employed instead, cast by the same or a similar process hereinbefore referred to with
respect to a hollow blank or cup; and which said solid cylinder is drilled by a similar
process as before described.

Improvements in the Manufacture or Production of Metallic Cart-
ridge Cases or Shells and in Appliances and Machinery to be
Employed therefor.
We, GEORGE KYNOCH of Lion Works, Witton near Birmingham in the County of
Warwick, Manufacturer, and JOSHUA CLARK of Witton Road, Aston Manor, near
Birmingham, aforesaid, Engineer, 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 :-
Our invention relates to the manufacture, or production of metallic cartridge cases
or shells, principally for machine guns, and cannon, by the combination of processes
and appliances, and machinery, hereinafter described.
Our invention consists first, in the formation or production of the blank, which is
in the form of a cast cup, or ferrule, with closed bottom; and from which said cup or
ferrule, a cartridge case or shell, is subsequently made. 2nd in the process of boring
or skinning the inside of the said cast cup, true, for the subsequent operations of
stretching and drawing, and in appliances and tools to be employed therefor. 3rd in
stretching or extending longitudinally, the walls of the shell, by removing a portion
of the metal from the thickened sides of a blank, by a process of displacement. 4th
in machinery to be employed in the drawing, and finishing processes.
In carrying out our improvements, we will describe them in connection with a
metallic cartridge case, for a machine gun or cannon.
The metal blank or cup, is produced by the process of casting, by employing a
metal mould, made in segments, or halves, and secured together by rings or snugs,
and pins.
The space within the mould is of a size equal to the cartridge blank, to be cast.
Within the inside of the said mould, a hanging or depending metal core, is disposed,
having an axial hole through its middle, and inclined vent holes through its sides,
leading to its middle; and through which vent holes, air or gaseous products given
off from the fused metal, pass away, in the process of casting, so as to prevent blow-
holes or honey-combing of the metal.
The internally hanging metallic core, is connected to, or carried on the underside
of a flange or plate, accurately fitting within a recess or the like, on the top of the
sides of the mould; so that on the said flange or the like, which has vent holes in it,
being dropped into position, the core becomes perfectly central.
Suitable gets are arranged, for the introduction or passage of the metal into the
interior of the said mould.
This
Figure 1 represents a complete vertical section of a segmental mould, for the
production by casting, of a metal blank or short cylinder closed at bottom.
blank or short cylinder is subsequently operated upon, by tools and processes herein-
after described.

page_text: Figure 2 represents a plan of the said mould, and figure 3 represents the hanging
or depending metallic core, which when placed in position, hangs within the middle of
the interior of the mould, and leaves a space surrounding it at bottom, of a size, equal
to the blank to be cast.
The same letters of reference indicate corresponding parts in figures 1, 2 and 3.
a, a, are the two halves or half segments of the metallic mould, secured and
clamped together, by rings b, b, which surround and embrace the outer periphery of
the said mould, although the said segments may if necessary be clamped together, by
snugs with eyes in them, through which affixing pins or the like, pass.
c is a depending metallic core, hanging centrally within the interior of the mould,
and kept in position, and supported by a collar c¹, and a flanged top c³, of which the
latter, rests upon the top of the mould, while the former fits accurately within the
inside top thereof.
are upwardly directed vent holes, leading from the interior of the mould, to
within the hollow axis c, of the core, and through which vent holes, and other
holes c, gaseous products given off from the fused metal, pass away, in the process of
casting.
The fused metal is introduced into the mould, by a get co.
Figure represents a modification of the said metallic mould. In this arrange-
ment, the direction of the mould, is inverted, and with an open top instead of a
closed one. Figure 5 is a plan of the said figure 4, and figure 6 is a section of the
solid core.
.a, a is the mould, 6 are securing rings, a² is the open mouth, and a³ is a closed
bottom of the said mould.
Disposed axially within the middle of the mould, is a solid core c, secured to the
base a³, by a neck and collar c, c7; the latter of which, seats itself within a like
recess, formed within the top side of the base, while the former passes through a hole
in the said base, and is secured in position, by a nut e³.
The blank cup or solid onded cylinder thus produced, is now bored or drilled to the
depth and diameter required, and the outside diameter skinned over by ordinary
cutting or shaping tools, so as to make the outside true to the inside, and also remove
scale.
The process of boring is conducted by machinery consisting of an arrangement of
parts similar in construction to an upright drill, provided with a self acting feed, and
a table at right angles thereto.
Thus, the machine consists essentially of a joggling carrier, or movable bed, which
is capable of moving in opposite directions; the bed may have snugs or uprights at
two opposite points, and against which, cross arms carried by a holding bush, is
joggled, in order to change or vary the position of the blank being operated upon,
with respect to the drilling or boring appliance.
The holding bush consists of a thick cylinder, of the external diameter, of the size
of a cartridge case or blank to be operated upon; and which said cylinder, is open at
top and bottom, with the latter, resting upon the top of the carrier bed, which is
supported thereunder, by the table or rest of the machine. Extending from the two
opposite sides of the lower end of the said bush, are carrying arms, which are
presented to the back and front of the snugs or uprights, carried by the said joggling
carrier.
This carrier bush is fitted with two or more set pins, near its base, so as to form
blank holding devices or clams; so that the said blank shall be held, and shall not
turn round, other than with the holder, by which the said blank is carried.
To completely fullfil this operation, other like machines, will be required to perform
subsequent operations, in completing the inside.
The next operation is the process of displaying a portion of the metal from the
thickened sides, and causing the said displaced metal to flow upwards, and increase or
lengthen out the walls of the shell. This process of displacement, is performed. or
accomplished, in a similar appliance, to that last described, for boring.
In carrying out this last named process, or processes of displacement, we use a

page_text: centrally disposed bulbous ended mandril or roller, which is forced down the inside,
(pressing upon the sides) of the partially prepared shell or blank, is at the same time
joggled, as by the aforesaid mechanical appliance or appliances.
The pressure thus exerted, by the mandril end or roller, acting inwardly upon the
sides of the blank, on the mandril being rotated and advanced, and the carrier and
blank joggled, causes the metal displaced, to flow upwards, and so stretch or elongate
longitudinally, the walls of the said case being operated upon.
This last named process or processes of displacement, or elongation, has the effect
of hardening, and stiffening the walls and sides of the shell, leaving the base thereof,
intact.
The turning and trueing of the outside with the inside, may be carried out, by
means commonly known.
Figure 7 represents in elevation, and figure 8 in vertical section, the blank or
closed ended cylinder, produced in either of the moulds previously described ; and
which said blank, is subsequently bored or drilled by means of a holder, bed and
cutter as shown at figure 9.
a is the boring or shaping tool, which is advanced by a self acting feed, and 6 is a
holder, carried by a movable bed or joggling carrier c, as hereinafter described
with respect to the process of stretching, or lengthening out the walls of the blank.
The blank d is secured in position, by a screw set pin i.
Figure 10 represents partly in elevation, and partly in vertical section, the said
apparatus or means, for elongating or lengthening out the sides of the blank or case,
subsequent to the final drawing through process or processes.
Figure 11 is a vertical section of the holder separately, and figure 12 is a plan of
the same, while figure 13 shows a complete plan of figure 10, and the table upon
which the joggling carrier rests, and is supported.
Figure 14 is a side elevation of the tool or mandril, by means of which, the metal
of the walls of the blank or case, is or are thinned and elongated, by a process of
displacement, created by a combined rotary and advancing movement of the eperating.
tool. Figure 15 is a an end elevation of the tool, figure 14.
The same letters of reference indicate corresponding parts in figures 10 to 15 both
inclusive of the drawings.
e,
a is a supporting table, and b is the holder of the blank, or partially formed case d;
and which case and holder, rest upon a slab or base plate c, which is carried by a
movable bed to which the base plate c, is connected by screw bolts c², whose lower
ends or heads c³, are placed within recesses e³, made in the bed e, while the upper
ends of the said bolts, are secured by nuts, and in order to admit of the base
plate c, having a slight lateral movement, with respect to its bed, the holes through
which the bolts pass, are made larger than the shanks of the bolts themselves, as
shown in the dotted lines figure 10.
The bed e, and parts carried by it, are carried by a slide f, with a longitudinal
dovetail rib, upon its top side, which takes and works within a like she dovetail
cross recess e³, made within the underside of the said bed e, so that the one part, is
capable of sliding transversely upon the other part.
The slide f, has upon its underside, longitudinal grooves ³, which take upon like
ribs a², disposed from end to end of the table a, and in a direction at right angles to
the dovetail rib f. By this means, the holder which is carried by the bed, is always
allowed to follow, or take the centre of motion of the operating tool, and which tool
consists of a mandril g, with a bulbous or swelled end 9 at its lower end; so that on
the said mandril being rotated, and at the same time advanced, and the blank within
its holder allowed to move in any horizontal direction, determined upon, by the
operating tool, the metal of the sides d³, of the case being operated upon, is caused
to flow, or be displaced, in an upward direction, thereby elongating, or stretching out
the walls of the said blank or case, as represented in figure 10.
The case d is secured within its holder b, by a clam h, pressed home by a set pin i,
as seen in figures 11 and 12.
The elongation of the walls of the case, as hereinbefore described, is followed by a

page_text: process of making the outside, true to the inside, which is accomplished, by shaping
tools, and cutters commonly known.
This partially formed cartridge shell, is further completed by a drawing or rolling
process, or processes, consisting essentially of machinery, arranged to work to and
fro, instead of only in a forward direction as heretofore.
The parts consist of a traversing cross head or heads, worked by twin screws,
(right and left handed) each situated at the outside ends of the cross head or heads,
and with the mandrils or punches, or their holders disposed centrally, and parallel to
each other, and in the same plane and direction as the screws.
The bed consists of a longitudinal frame, supported upon legs, or rests, and with
suitable bracket bearings, for carrying the cross head or heads, screws, and other
parts; and which said screws are provided at each of their ends, with driving toothed
wheels, which gear with pinions, inounted upon a shaft, carrying four pulleys, two
loose and two fixed; or by means of friction clutches, in connection with the pulleys ;
and through which said train of wheels and pulleys, an alternating traversing motion
is given to the cross head, carrying the mandril or punch holders. The holders of
the mandrils or punches are so arranged, that a cartridge shell, is being operated
upon, on the forward motion, as well as by the backward motion.
The framing or bed, may have side troughs, partially surrounding the screws, and
wherein a suitable lubricant is placed.
The screws pass through screw boxes, in the cross heads, and which cross heads
traverse in suitable guides made in the framing.
Instead of employing a hollow blank, ferrule or cup, a solid cylinder may be
employed, cast by the same, or by a similar process herein before described, with
respect to a hollow blank or cup; and which said solid cylinder, is subsequently
"drilled, by a process, similar to that already described.
Figure 16 represents partly in longitudinal section, and partly in elevation,
cartridge shell drawing machinery, constructed according to our said invention, and
which machinery, is made to draw or operate upon cartridge shells, cases or tubes ;
both in a forward, and in a backward direction.
Figure 17 is a top side plan of the said machine, with the bearing portions on one
side in section.
Figure 18 is a transverse vertical section of the said machine, and upon the dotted
lines A B figure 17.
Figure 19 shows a section of one of the dies, (upon an enlarged scale) and figure 20,
an elevation of the same.
Figure 21 is a front elevation of the mandril, upon the same scale as figure 19, and
figure 22 is a longitudinal section of a finished cartridge shell.
Figure 23 represents upon a reduced scale, to the several last named figures, a
cartridge shell in the act of being drawn through a die.
The same letters of reference indicate corresponding parts in figures 16 to 23 both
inclusive of the drawings.
a is the framing of the machine, with a top bed a², upon which a mandril or punch
carrying saddle or cross head & slides, and is reciprocated to and fro, by means of
twin screws c, c, supported and rotated within end framings, or cross ends a³; that
is, the necks c² of the screws c at the offside of the machine, work within plain gun
metal bearings c, and are secured in position by collars, and lock nuts c, while
the other plain ends of the screw axes e, work within plain bearings c', carried by the
front cross framing a³.
The saddle b, carries upon its two opposite sides, mandril or punch holders d,
which carry mandrils or punches d, and which said mandrils or punches are
arranged in pairs, and with their acting ends, presented in opposite directions, and
in coincident lines with the dies e, carried by fixed die carriers e³, crossing the open
middle part of the bed and fixedly secured thereto.
The screws c, pass through screw boxes f, carried by the saddle or movable cross
head; so that the rotation in either one or other direction of the twin screws, causes
the mandrils or punches d³ to be reciprocated to and fro, and with the partly formed

page_text: cartridge shells, upon the end of the mandrils, alternately taken through the
respective sets of dies.
The screws c carry at their near ends, tangent wheels y, which are driven by a
tangent pinion h, carried at the back end of a driving shaft i, which carries at its
other end, loose pulleys j, j', with which a double faced chuck k, alternately engages,
on the motion of the saddle, or the mandril carriers requiring to be changed.
Thus, the shaft i which is supported upon pillar framings 1, 1, has loose pulleys jj,
running thereon, and with the inner faces of the said pulleys, provided with clutch
annular depressions, wherein the acting parts k² of the clutch, alternately take, on
the said clutch being moved to and fro, by means of a clutch carrier or pin k³,
carried by the end of a depending arm k, suspended from the top of a pillar, and
operated by a connecting rod ko, connected and jointed to a transmitting rod k',
whose other end, is connected with a lever k8; so that on the moving of the said lever
backwards and forwards, the acting faces of the clutches, are made to engage
alternately with the respective driving pulleys.
The driving pulleys are rotated in reverse directions, and with the outer pulley j
preferably provided with a cross band; and on the clutch being in gear with the
pulley, the mandrils or punches are made to traverse in the direction as indicated
by the arrow.
When, the machine is at work, the blanks to be drawn, are placed upon the
respective acting ends of the mandrils, when the saddle is at the respective ends of
its traverse; and when in this position, the motion is reversed, by changing the
position of the clutch, which is done by the pulling of the lever k8, and thus making
the clutch slide longitudinally upon the feathers on the shaft i, and with the opposite
sides of the clutch, engaging with the opposite loose pulley, which is now made tight
on the shaft, and the saddle and mandrils carried by it, are made to traverse in a
reverse direction, and with the mandrils on one side, drawing or forcing the blanks
through the dies, while on the other side, the blanks and mandrils are being with-
drawn from the eyes of the dies; and after having been fully withdrawn, by the
saddle passing to the end of its traverse, the drawn or operated upon cases, fall from
out of the dies, on to the bed; and when the mandrils or punches are in this position,
fresh blanks are placed thereon, which are then subsequently drawn, on a reverse
action being given to the machine, by the transferring of the clutch, from one pulley,
to the other.
To change the speed of the gear, intermediate gear wheels may be employed, such
for example, as the placing of a sliding pinion m, which is in one piece with the
pinion h, upon the shaft i, which has feathers upon it; so that when a change of speed
is required, the pinions h, and m, are moved longitudinally upon the shaft, when the
pinion is taken out of gear, with the tangent wheels g, and the pinion m, taken out
into gear with the intermediate wheel n; on the pinion p, being moved outwardly
upon its shaft, it is made to gear with the wheels g.
The change of position of both upper and lower shafts, is effected by screw
adjusters o, which work through pillar supports o² fixed by the main framing.
Thus, when ordinary speed is required, the adjuster o is screwed inwardly, with the
pinion in gear with the wheels g; but when greater power is required, and speed
reduced, then the said pinion h is put out of gear with the said wheels, and the
pinion p, made to gear with them instead, by the top, and lower adjusters o, being
worked in reverse directions, so as to make the pinion m, engage with wheeln,and the
pinion p, with wheels g..
The clutch k is automatically and alternately made to engage with the pulleys,
by arrangements consisting of a rod q, working within bearing brackets q², to which
the arm k carried at the lower jointed end of the lever is connected at its
upper end.
'
The transmitting rod k', carries upright arms or dogs r,, which are also connected
at their upper ends, to the rod 7; so that on the saddle b, traversing to the end of its
course, in either one or other direction, it comes against the upright arms r, and
reverses the direction of the machine, by taking the clutch, from one pulley, and

page_text: placing it in the other; and which motion takes place through the intervention of the
rod k, link, hanging link &, and stud ³, at its lower end, thus causing the clutch,
to slide upon the feathered shaft as desired.
Thus, when the saddle arrives near the end of its stroke from left to right, it comes
in contact with the upright arm r, and carries it forward in that direction, which by
the motion of the said arm, the transmitting rod is moved in the same direction, which
takes the clutch into action, with the pulley j, so as to make shaft, clutch and pulley
rotate together.
On the saddle moving in a reverse direction, and near the end of its stroke, it comes
in contact with the other arm r³, and takes the clutch into the adjacent pulley, and
thereby changes the direction of motion of the saddle.
