Improvements in Marking Cartridge Cases.
I, ARTHUR CHAMBERLAIN of No 4 New Bartholomew Street Birmingham in
the County of Warwick Manufacturer do hereby declare the nature of this
invention to be as follows:-
My invention relates to printing or marking cartridge cases and its object is to
print or mark such cases so that any desired words or impression may be imprinted
upon the cylindrical surface of each case after the case has been manufactured. In
one mode of carrying my invention into effect I prepare ink of a nature which does
not smear on a highly polished surface; such an ink may be made with lamp black
and copal varnish, and ink a convenient stamp so arranged that the cylindrical
case is rolled over the printing surface. The cylindrical cartridge case is rolled or
rotated in any convenient manner and it is preferably carried on a mandril which
mandril is rotated and caused to slide in a predetermined manner, so as to print or
mark the case as required.
The printing types die or dies are pressed on the rolling or rotating case with
the required pressure and the types or dies are set so as to print or impress
diagonally round the cartridge or otherwise as desired. The types or dies may he
cylindrical and the rotating surfaces of dies and cartridge cases may be pressed
together by any known device. It is preferred to make the ink used damp resisting
as well as non-smearing.

COMPLETE SPECIFICATION.
Improvements in Marking Cartridge Cases.
I, ARTHUR CHAMBERLAIN, of 4 New Bartholomew Street, in the City of
Birmingham, Manufacturer, 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:-
My invention relates to printing or marking cartridge cases and its object is to
print or mark such cases so that any desired words or impression may be imprinted
upon the cylindrical surface of each case after the case has been manufactured.
In one mode of carrying my invention into effect I prepare ink of a nature which
does not smear on a highly polished surface.; such an ink. may be made with lamp
black and copal varnish and a drying oil, and 1 ink a convenient stamp so arranged
that the cylindrical case is rolled over the printing surface.
The cylindrical cartridge case is rolled or rotated in any convenient manner and
it is preferably carried on a mandril which inaudril is rotated and caused to slide
in a predetermined manner so as to print or mark the case as required.
The printing types die or dies are pressed on the rolling or rotating case with the
required pressure and the types or dies are set so as to print or impress diagonally
round the cartridge or otherwise as desired. The types or dies may be cylindrical
and the rotating surfaces of dies and cartridge cases may be pressed together by
any known device.
It is preferred to make the ink used damp resisting, as well, as non-smearing.

page_text: Referring to the four accompanying sheets of drawings which illustrate a
printing machine for printing cartridge cases in accordance with my invention :-
Figure 1 is a plan.”
Figure 2 is a longitudinal section part in elevation.
Figure 3 is an end elevation looking on the driving pulley end of the machine.
Figure 4 is a traverse section through the feeding shoot.
Figure 5 is an elevation of the feeding shoot and slide looking on the front of the
machine as in Figure 2.
The
The cartridge cases to be printed are fed into the incline A (Figures 1 and 4)
and pass at the bottom of the said incline into the recess B' of the slide B which
slide is operated by suitable levers from a main driven shaft I driven by pulley H.
H is a loose pulley. The picking up arrangement C2 acting on the end of a lever C
picks the cartridge case out of the recess when the slide B is pushed out.
picking up arrangement consists of a spring clip C so arranged that when the
ends touch the cartridge case while it is lying in the recess 131 of the slide B, then
the said clip ends open being pressed down by the lever C1 and spring over the case
encircling it and lifting it (when the lever C rises) ont of the said recess. On the
next downward movement of the lever C the clip C carries with it the cartridge
case. The lever is operated as to rising and falling by a suitably shaped cam
carried on the shaft I. This picking up arrangement is well known among
cartridge manufacturers and is in common use, and it does not form any part of this
invention. The pick up arrangement C2 after the withdrawal of the slide B places
the cartridge case in a gap between the end G¹ of the sliding spindle G and the
end of the rotating mandril D, and then the slide G advances carrying with it the
sliding sleeve D' so that the cartridge case is pushed on the said mandril, D. A
cylindrical type surface E then comes round and prints or impresses the required
natter on the surface of the cartridge case. During this operation the case is
pressed up against the type surface or held up against it by the roller L carried by
the lever LL which lever is operated from the shaft by the cam M. This
pressing up by the roller L prevents the mandril D from being sprung off the type
surface.
When the case is printed the slide G moves back again carrying with it the
sliding-sleeve D¹ by the connecting piece K. The cartridge case is thus discharged
from the machine and the action proceeds as described to print the next case.
The slide G is operated from the shaft I by the slot cain J.
The type surface E is also operated from I by a train of toothed wheels indicated
at O which train is continued to operate the inking rollers F.
There is a gap in the cylindrical surface of the printing roller E, that is, only
part of the surface is cylindrical, so as to permit the cartridge case to be brought
into position and withdrawn without contact with the types except at the moment
of printing.
It is to be noted that minute description of the feeding and inking mechanism of
my machine is not required as the arrangements illustrated are well known and do
not constitute any part of this invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. Cartridge case printing or marking mechanism by which a cartridge case is
printed on its cylindrical surface, the cartridge case being rotated on a mandril and
held up to rotating cylindrical types substantially as hereinbefore described.
2. The cartridge case printing machine hereinbefore described comprising:―a
rotating mandril to carry the said case and rotate it against types; and a sleeve
with a sliding movement to permit of cases being fed to and discharged from the
mandril substantially as herein before described with reference to Figures 1, 2, 3, 4
and 5 of the accompanying drawings..

page_text: 3. In cartridge case printing mechanism the use of an ink composed of a varnish
such as copal varnish and a pigment such as lamp black with a drying oil for the
purpose of printing on a highly polished surface without smearing.
