We JOSEPH SAMUEL TAYLOR and STEPHEN WILLIAM CHALLEN both of Derwent
Foundry, Constitution Hill, Birmingham in the County of Warwick, Engineers,
do hereby declare the nature of this invention to be as follows:-
Our invention relates more particularly to Steam Stamps for heading metallic
cartridge cases and to mechanical arrangements for ejecting the cases from the bolster
when headed, but it may also be applied to hydraulic stamps and it may be used for
other similar metallic cases.
In using stamps as hitherto constructed, for heading cartridge cases, after striking
the necessary blow or blows and forming the head, it is sometimes difficult to eject
the case from the boltster and time is lost in ejecting it previously to inserting.
another.
The object of our present invention is to avoid this difficulty and to mechanically
eject the metallic case with ease and certainty, at the same time allowing the
operator freedom to strike as many blows as may be necessary to properly form the
head.
In carrying out our invention we arrange a steam stamp above a bolster set in an
anvil or hammer block, the bolster is formed to receive the case, and a pin fills the
interior of the case, which pin is securely attached to a sliding piece; this sliding
piece fits and moves in a suitable space in the anvil or hammer block and it is raised
or lowered by a lever the end of which works freely in a slot in the sliding piece.
The lever works upon a pin passing through the anvil or hammer block and while
one end actuates the ejector pin the other end is formed to carry a block sliding in
a long slot. This block forms the connecting piece between the crank pin of a crank
shaft and the lever, and when the crank shaft revolves the end of the lever and there-
fore the ejector pin moves up and down.
The crank shaft is driven from a driving shaft by means of a wheel and pinion,
the pinion on the driving shaft is not keyed on but runs freely on it and is only
caused to rotate with the shaft at the required time by means of a friction clutch;
the clutch is put into action by a hand lever so arranged that when lifted up a spring
acting upon it puts in the clutch and a cam which is keyed upon the end of the crank
shaft on moving round engages a pin in the hand lever and by moving it against
the spring throws out the clutch and stops the pinion and therefore the crank shaft.
So long as the hand lever is allowed to rest on the crank shaft the cam prevents the
spring from thrusting in the clutch but whenever the lever is lifted to disengage the
pin from the cam then the spring acts and throws in the clutch; so long as the hand
lever is held up the pinion will be driven by the shaft and the crank shaft will move
round, but it is only necessary to lift it out of contact with the cam and let it go, when
it rests upon its cam which is so shaped as to engage the pin at the proper time, so
that the crank makes one revolution causes the lever end to move up and down and
then stops with the crank pin in its upper position.
The end of the lever working in the sliding piece carrying the ejector pin, works
very easily in the slot enough clearance being left to allow the piece to rest solidly
upon the anvil or hammer block and free from the lever while the crank is in its
upper position at which it is always stopped by the cam. By so arranging, the blow
upon the cartridge case to form the head is not transmitted to the lever but takeu
entirely by the anvil or hammer block. The operation of heading a cartridge case
is as follows:-A cartridge case is slipped on the ejector pin and into the bolster,
the steam stamp is then caused to give as many blows as are necessary to properly

page_text: form the head and the hand lever is lifted, at once, the friction clutch acts and the
pinion drives the wheel upon the-crank shaft- causing the lever to move and thrust
up the ejector pin, the case is thus ejected and the crank shaft completes a revolution,
its cam at the proper moment engaging the hand lever and throwing out the pinion
clutch so that the crank stops in its upper position leaving everything ready for
another operation.
The two shafts are carried on suitable framing and the driving shaft may be
actuated by belt or in any other convenient manner. The friction clutch may be of
any known kind; the hand lever connections are arranged to allow the pin upon
which it pivots a vertical movement, so as to allow of the double action of lifting out
of gear with the cam, and the thrust of the spring at right angles to the plane of
lifting to put in the clutch. The crank shaft may be connected to the ejecting pin
lever in any other well known manner.
The ejecting pin lever may be actuated by a hydraulic ram with withdrawing
action or by a steam cylinder and piston in which case an oil, or water cataract will
be required to control its rate of movement.
The water or steam power may be applied direct by rams
or pistons to the
ejecting pin using precautions to prevent the force of the stamping blow reaching the
ram or pistions.
The stamping cylinder may also be actuated by hydraulic power instead of steam
power if so desired.

Improvements in Steam and Hydraulic Stamps and Mechanism
Connected therewith.
We, JOSEPH SAMUEL TAYLOR and STEPHEN WILLIAM CHALLEN both of Derwent
Foundry, Constitution Hill Birmingham, in the County of Warwick Engineers,
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 more particularly to Steam Stamps for heading metallic
cartridge cases and to mechanical arrangements for ejecting the cases from the bolster
when headed, but it may also be applied to, hydraulic stamps and it may be used for
other similar metallic cases.
In using stamps as hitherto constructed for heading cartridge cases, after striking
the necessary blow or blows and forming the head, it is sometimes difficult to
eject the case from the bolster and time is lost in ejecting it previously to inserting
another.
The object of our present inventions is to avoid this difficulty, and to mechanically
eject the metallic case with ease and certainty, at the same time allowing the
operator freedom to strike as many blows as may be necessary to properly form the
head.
In carrying out our invention we arrange a steam stamp above a bolster set in
an anvil or hammer block,, the bolster, is formed to receive the case,, and a, pin; fills
the interior of the case, which pin is securely attached to a sliding, piece; this, sliding.
piece fits and moves in a suitable space in the anvil or hammer block, and it is
raised or lowered by a lever the end of which works freely in a slot in the sliding
piece.
The lever works, upon a pin passing through the anvil or hammer block and
while one end actuates the ejector pin the other end is, formed to carry a block
sliding in a long slot. This block forms the connecting piece between the crank
pin of a crank shaft and the lever, and when the crank shaft revolves, the end of
the lever and therefore the ejector pin moves up and down.

page_text: The crank shaft is driven from a driving shaft by means of a wheel and pinion,
the pinion on the driving shaft is not keyed on but runs freely on it and is only
caused to rotate with the shaft at the required time by means of a friction clutch:
the clutch is put into action by a hand lever so arranged that when lifted up a
spring acting upon it puts in the clutch and a cam which is keyed upon the end of
the crank shaft on moving round engages a pin in: the hand lever and by moving
it against the spring throws out the clutch and stops the pinion and therefore the
crank shaft.
So long as the hand lever is allowed to rest on the crank shaft the cam prevents
the spring from thrusting in the clutch but whenever the lever is lifted to disengage
the pin from the cam then the spring acts and throws in the clutch; so long as
the hand lever is held up the pinion will be driven by the shaft and the crank shaft
will move round, but it only necessary to lift it out of contact with the cam and
let it go, when rests upon its cam which is so shaped as to engage the pin at the
proper time, so that the crank makes one revolution causes the lever end to move
up and down and then stops with the crank pin in its upper position.
The end of the lever working in the sliding piece carrying the ejector pin, works
very easily in the slot enough clearance being left to allow the piece to rest solidly
upon the anvil or hammer block and free from the lever while the crank is in its
upper position at which it is always stopped by the cam.
By so arranging, the blow upon the cartridge case to form the head is not
transmitted to the lever but taken entirely by the anvil or hammer block. The
operation of heading a cartridge case is a follows :-
A cartridge case is slipped on the ejector pin and into the bolster, the steam stamp
is then caused to give as many blows as are necessary to properly form the head
and the hand lever is lifted, at once the friction clutch acts and the pinion drives
the wheel upon the crank shaft causing the lever to move and thrust up the ejector
pin, the case is thus ejected and the crank shaft completes a revolution, its cam at
the proper moment engaging the hand lever, and throwing out the pinion clutch so
that the crank stops in its upper position leaving everything ready for another
operation.
The two shafts are carried on suitable framing and the driving shaft may be
actuated by belt or in any other convenient manner. The Friction clutch may be
of any known kind; the hand. lever connections are arranged to allow the pin upon
which it pivots a vertical movement, so as to allow of the double action of lifting
out of gear with the cam, and the thrust of the spring at right angles to the plane
of lifting to put in the clutch. The crank shaft.may be connected to the ejecting
pin lever in any other well known manner.
The ejecting pin lever may be actuated by a hydraulic ram with withdrawing
action or by a steam cylinder and piston in which case an oil or water cataract will
be required to control its rate of movement.
The water or steam power may be applied direct by rams or pistons to the
ejecting pin using precautions to prevent the force of the stamping blow reaching
the ram or piston.
The stamping cylinder may also be actuated by hydraulic power instead of steam
power if so desired.
And in order that our invention may be fully understood and readily carried
into effect we append two sheets of drawings to be hereinafter referred to.
Figure 1 Sheet 1 is a side elevation partly in section of one application of our
invention to a steam stamp for heading metallic cartridge cases, Figure 2. is an end
elevation also partly in section. Figure 3 Sheet 2 is a side elevation of the lower
portion of the stamp showing the external arrangement of clutch lever and
which Figure 4 is a plan of that portion with the anvil block partly in section.
Figures 5, 6 and 7 show the Clutch details on an enlarged scale.
gear
The Steam Cylinder A of the Steam Stamp has the hammer B striking the case
placed upon the anvil or hammer block C and the bolster or die D is suitably shaped
to form the head. The case slips over the ejector pin E and when a sufficient

page_text: :
number of blows have been delivered to properly form the head the Clutch lever F
(Figures 2, 3, and 4) is lifted by hand when the spring G thrusts it outwards and
as it pivots at H the end I coupled to the clutch J pushes the clutch into gear and
causes the pinion K to rotate and actuate the toothed wheel L. The wheel L
revolves the shaft M and with it the crank pin N, and through the sliding block O
this moves the lever P pivotting on the pin Q and the ejector pin E is raised up
and ejects the cartridge case. The Shaft M has upon its end a cam disc R engaging
a pin S upon the clutch lever F and so shaped upon the side that as the shaft revolves
the Clutch lever falls down and the pin S is thrust inwards against the spring G
this disengages the clutch and the motion is arrested. The cam is placed in such
position on the inner surface of the cam disc R that the motion of the crank pin is
arrested when the ejector pin block T is in its lowest position and the end of the
lever P is left sufficiently free in the block T to prevent the shock of the blow upon
the end of cartridge case being transmitted to the lever.
When the lever F is lifted up then the pin S is lifted clear of the cam surface and
the end of the pin rests upon the periphery of the cam disc R so that the spring G
is at liberty to thrust out the lever and put in the clutch. So long therefore as the
lever F is held up the clutch remains in gear and the shaft M revolves as the
shaft U is in continual rotation driven by a belt upon the pulley V. The ejector pin
then continues to move up and down. If the lever F be let go then the pin S comes
in contact with the cam surface and the lever is thrust against the spring G which
causes the other end to disengage the clutch J from the pinion K. If the lever F
be lifted and then let go at once the shaft M makes one revolution only and one up
and down movement of the ejector pin and is then stopped as described.
Suitable framing and bearings are provided for carrying the shafts M and U
which details are of any usual construction and do not require any special reference or
.description.
The pinion K shewn in a larger scale at Figure 5 contains a conical surface and it
works freely on the shaft U; the cone Clutch J is keyed to the shaft U but slides
along it as determined by the clutch lever F and when pressed into the conical part
of the pinion K the pinion is rotated with the shaft U.
The lever F is pivotted at the fulcrum H which as shewn at Figures 3 and 4
consists of a bolt W having a slotted piece at H, as shewn by dotted lines, through
which the lever F passes: the slotted bolt W is carried by the wrought Iron
projections or horns X X. The construction of this part may be varied but the.
essential point is to allow a free vertical movement of the lever F while permitting
at the same time a spring such as G to move the lever so as to force in the clutch J.
This compound movement may be obtained with varying constructions thus the
lever F may have a slot in it instead of the bolt W or the necessary freedom may be
allowed in some other way.
The Steam Cylinder A may be replaced by an hydraulic cylinder without
modifying the mechanism we have described for ejecting the cases.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
I. In steam and hydraulic stamps the use of an ejector pin actuated mechanically
in such manner that one movement of a hand lever causes the ejector pin to operate
. and return to rest substantially as and for the purposes herein before described.
II. The combination of parts forming our improved ejector for steam and,
hydraulic stamps with the actuating mechanism therefor as herein before described
with reference to Figs. 1, 2, 3 and 4 of the accompanying drawings.
III. In steam and hydraulic stamps the combination of the cam disc R with the
lever F, spring G, slotted bolt H or the equivalent, and clutch such as J, so that on
the lever one revolution of the cam shaft is given only, substantially as and for the
purposes hereinbefore described reference being had to the accompanying drawings.
IV. In stamps or presses, the use of a lever such as F, together with a cam disc

page_text: such as R the lever having a compound movement whereby it can be moved in one
direction while a spring acts at or near right angles to the plane of the first
movement and causes a clutch such as J to be put into gear, substantially as and
for the purposes herein set forth reference being had to the accompanying
drawings.
