I, ALFRED JULIUS BOULT of the Agency for Foreign Patent Solicitors 323, High
Holborn in the County of Middlesex and 6, Lord Street Liverpool in the County of
Lancaster Engineer do hereby declare the nature of this invention (a communication
from abroad by George W. Morse of Philadelphia in the State of Pennsylvania,
United States of America) 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 implement for resizing cartridge cases for fire arms
and its object is to provide a press for reducing the diameter of a cartridge
throughout its entire length and at the same operation to resize the head and
bullet and to crimp the case into the bullet.
In the drawings:
:
Figure 1 is a perspective showing this invention.
Figure 2 is a vertical section of the same showing the clamping jaws closed
upon a cartridge, the head compressor and crimping dies in operative position.
Figure 3 is a horizontal section through the middle of the tool showing screws.
for setting up and securing the reducing jaws in the frame.
A is a frame or buckle within which the jaws and toggle are fitted and
sustained.
B and B are jaws channeled on their adjacent sides to form a die of the proper
size for a cartridge before it is fired.
C is an eccentrically socketed cylinder forming one part of a toggle.
D is a link or bar forming the thrust of the toggle. E is a head compressing
plate. The buckle or frame A is preferably made of cast steel and provided with
ribs. It is also provided with bosses a, a, and a³, and with an arm or handle A¹.
This buckle bas an oblong rectangular interior opening to receive the com-
pressing jaws or dies and a cylindrical socket for the cylinder C.
The jaws B and B¹, are made to loosely fit in the rectangular opening in the
frame or buckle:

page_text: They are channeled along one side and have a hardened steel spline b, let into
them against which set screws in the boss a¹ bear to hold them in place in the
frame and firmly against one side of the interior opening.
The set screws in bosses a, a, operate to set up the fixed jaw B¹ and adjust it in
its proper relation to the movable jaw.
The movable jaw B is provided with a vertical cylindrical socket to receive one
end of the link D, of the toggle.
The adjacent faces of the jaws have central vertical, semi-cylindrical grooves or
channels, which, when the jaws are together form a socket or die in which the
cartridge case is resized. The edges of the jaws which come in contact with each
other are serrated or provided with teeth which mesh with each other when the
jaws are closed. These teeth lap each other and thus the entire circumference of
the cartridge is supported in the die while it is being compressed.
The jaws are chamfered or cut away as shown at d, to make the abutting edges
narrow to avoid obstructions by dirt or grease. These serrations are also chamfered
just up to a line forming one half of the whole die so that when the jaws are apart
the width of the opening in the die will be enough to admit an expanded cartridge
case. The jaws B, B¹, are also provided with lips 61 61. These lips are beveled as
shown for operation upon the. head compressor E. This compressor reduces the
thickness of the head of the cartridge to its proper dimensions in the operation of
bringing the jaws together before the diameter of the body of the cartridge is
reduced.
These jaws are provided with interior projections e, e, to crimp or force portions
of the shell into one of the grooves or cannelures of the projectile to hold it in the
case. These may be dispensed with altogether or the dies may be made to crimp
the mouth of the shell.
The toggle for operating the movable jaw consists of an eccentrically socketed
cylinder C, provided with a handle C₁ and a link or bar D, having heads or
bearings and a web between as shown in Figure 3.
The cylinder C, is fitted in its socket in the frame as shown at Figures 1 and 3,
and its arm or lever swings in a plane above the frame. The heads of the link, or
bar D, fit in corresponding sockets in the movable jaw and the cylinder C.
The web of the link D, is cut away leaving pintles on the heade as shown in
Figure 2. One of these pintles has a bearing in a perforation through the handle
plate C, and another in a disc f, secured to the bottom of the cylinder.
The rotation of the cylinder C throws the link and attached jaw forward or
backward according to the direction in which the handle C', is moved.
This mechanism gives great power with adequate strength of parts in a narrow
space and is therefore especially adapted for a hand tool requiring great force.
The operation of this improved resizing press is as follows: The jaws being open,
an expanded cartridge loaded or unloaded is inserted in the socket between the
jaws, the plate E is then placed in position under the lips b, b, whereupon the
handle C¹ is operated and the jaws closed. In doing this the inclines of lips b¹, b',
first come into operation to. bring the plate, E, down to compress and reduce the
thickness of the head of the cartridge after which the jaws clamp and reduce
the cartridge to the predetermined size.
It will be observed that the dies press upon the shell from end to end, and that
all the parts of the shell and projectile are compressed simultaneously. This insures
perfect conformation of the outer surface of the entire cartridge to the shape and
dimensions of the resizing die.
It is observed that the operation of the jaws of this tool is substantially like
that of the jaws of a lathe chuck and it will be understood that more than two
jaws may be combined to carry out the principle of this invention.
I claim as my invention :-
1. In a cartridge resizing press the combination of a plurality of is we or dies

page_text: a common centre whereby the diameter of a cartridge is reduced by the application
of force to the entire exterior of the body acting in a direction exactly opposite to
that which expanded it as specified.
2. In a cartridge resizing press the combination of jaws or dies embracing the
cartridges, moving toward and from each other and a compressing plate co-operating
therewith, for reducing the thickness of the head while the cartridge is retained
within the jaws, substantially as described.
3. In a cartridge resizing press the combination of jaws or dies provided with
inclined flanges or lips on their heads as b, b, and a head compressing plate
substantially as set forth.
4. In a cartridge resizing press the combination of a frame, jawa or dies
embracing the cartridge and moving with relation to each other toward a common
centre and a toggle for operating the movable jaw as specified.
5. The combination in a cartridge resizing press of a toggle consisting of an
eccentrically socketed cylinder and a bar or link, one end of which is pivoted in
one of the movable jaws of the press, and the other in the eccentric socket of the
cylinder as shown and described.
6. The combination in a cartridge resizing press of a jaw or die adjustably fixed
in the frame, a jaw or die movable in relation thereto, and a toggle for operating
the movable jaw as specified.
7. In a cartridge resizing press the combination of a plurality of interlocking,
serrated or notched jaws or dies substantially as described.
