at the Office of the Commissioners of Patents, with his Petition,
on the 24th April 1872:
I, WILLIAM ARMAND GILBEB, of the Firm of L. de Fontainemoreau
5 & Co., Patent Agents, 4, South Street, Finsbury, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF SHELLS AND SHOT, AND IN THE

page_text: MACHINERY OR APPARATUS EMPLOYED THEREFOR," to be as follows, that is to
say :-

The object of this Invention is improvements in the finishing of
conical shells and shot by which they are cleaned from the rough casting
in a much more rapid and economical manner than by the present 5
method of turning, and the Invention consists in forcing the shells or
shot by means of an improved screw or hydraulic press through a scries
of cutter blocks arranged as herein-after described. The improved screw
press has three columns, and at the base of each column is a lever rest
and a cutter block, both of which are movcable round the column,
that they may be brought as required to the centre of the press. Tho
first cutter block is fitted with round cutters in order to cut grooves
around the shell or shot, the second cutter block is fitted with curved
cutters in order to take off the projections left by the first cutters, and
the third cutter block is fitted with three or more curved cutters in such ]
manner that their abutments will correspond with the centre line of the
spiral feathers or buttons on the shell or shot. Underneath the press
is a moveable centre supported by a chain which descends from the
guide pin of the screw at one side and is connected on the other side by
a tackle. A guide is connected to the screw of the press (or to the ram
if a hydraulic press be employed) to give the required twist of the
spiral feathers or buttons on the shell or shot.
. The action of the machinery or apparatus is as follows:-The first cutter
block and then the three lever rests are swung into position, and a
shell or shot is placed on the latter, the tackle is then hauled taut and
fastened by the chain screw by which the shell or shot is fixed between
the moveable centre and the screw of the press. The three lever rests
are next moved away from under the shell or shot and the guide bar
is arranged to suit the twist of the shell or shot, and the press is started.
When the shell or shot has passed the first cutter block the tackle is
slackened and the screw of the press raised. The first cutter block is
then swung out of the way and the tackle hauled taut to bring up the
shell or shot under which the lever rests are again brought, the move-
able centre being next lowered, the second cutter block is brought into
position, and the tackle hauled taut and fastened as before described,
the lever rests are moved away and the press started. The operation
for the third cutter block is the same as that described for the second
block.

filed by the said William Armand Gilbee in the Great Seal Patent
Office on the 21st October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ARMAND GILBEE, of the Firm of L. de Fontainemoreau & Oo., Patent
Agents, 4, South Street, Finsbury, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of April, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Armand Gilbee, Her special
licence that I, the said William Armand Gilbee, my executors, admi-
nistrators, and assigns, or such others as I, the said William Armand
Gilbee, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF SHELLS AND SHOT, AND IN THE
MACHINERY OR APPARATUS EMPLOYED THEREFOB," (a .communication from
abroad by William Shelbourne Icely, of Constantinople, Turkey, upon
the condition (amongst others) that I, the said William Armand Gilbeo,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
..NOW KNOW YE, that I, the said William Armand Gilbee, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing herçto

page_text: annexed, and to the figures and letters marked thereon thereon, that
is to say :-
The object of this Invention is improvements in the finishing of
conical shells and shot, by which they are cleaned from the rough
casting in a much more rapid and economical manner than by the 5
present method of turning and planing; and the Invention consists in
forcing the shells or shot by means of an improved screw or hydraulic
press through a series of cutter blocks constructed and arranged as
herein after described,
"
To make the Invention better understood I will proceed to describe 1
the same by reference to the accompanying Drawing, in which Figure I
is a plan, Figure 2 a front clevation, and Figure 3 a side clevation of
the improved machinery (arranged as a screw press) for finishing
conical shells and shot; Figure 4 is a horizontal section of same on
lino A, B, Figure 1. Similar letters in all the Figures are used to 1
represont similar parts.
The improved machinery is constructed with three columns a, a', a³,
bolted to the cast-iron bottom plato A, A, and to the top plate B, in
which works the screw of the press. At the base of cach column is a
lever rest and a cutter block, the lever rests are marked respectively
b, b', ', and the cutter blocks c, c', c³, the lever rests and cutter blocks
move round the columns, and thus may be brought as required to the
centre of the press exactly under the screw. The first cutter block c is
fitted with round cutters d (one of which is shewn detached on a
larger scale in plan and elevation at Figures 5 and 6), which serve to 2
cut longitudinal grooves on the circumference of the shell or shot, the
second cutter block c' is provided with curved cutters e in order to take
off the projections left by the first cutters d.
Figure 7 is a plan, and Figure 8 an elevation on a larger scale of one
of the cutters e detached, The third cutter block c³ is fitted with three 3
or more curved cutters f, so arranged that their abutments shall corre-
spond with the centre line of the spiral feathers or buttons on the sholl
or shot.
Figure 9 is a detached sectional view of one of the cutters f. Under-
neath the screw 7 of the press is a moveable centre h; this moveable a
centre is supported by the chain i, which descends from the guide pin i¹
of the screw at one side, and is connected to the press on the other sido

page_text: by the tackle j; k, endless screw, and 2, worm wheel for working the
screw of the press; m, m³, large fast and loose pulleys at one end of the
shaft of the endless sorew k, the other end of the shaft being provided
with the small fast and loose pulleys n, n'.
Figure 10 is an elevation shewing the guide bar o, attached to the
column a, by the slotted supports p, p', shewn respectively in plan at
Figures 11 and 12.
The operation of the machine is as follows, viz-The three lover
rests b, b', b', are brought to the centre of the machine, as seen in
Figure 4, and a shell a placed thereon, the first cutter block c is then
turned round to the centre underneath the lever rests, the moveable
centre is raised by hauling taut the tackle j, and fastening the same to
the main chain i, or a weight may be hung on the fall, by which
operation the shell q is fixed between the moveable centre h and the
chuck on the main screw 9 of the press, (or on the ram of the
hydraulic press when used,) the lover rests being thus relieved of the
shell are turned out of the way, the machino is started by the large
pulleys m, m', and the shell will be forced through the first outter
block c, and will be cut with longitudinal grooves all round by the
cutters d. The tackle j must now be slackened, and the main screw g
run up by the small pulleys n, n', the cutter block c must be moved away,
and the shell hauled up again and placed on the lever rests, the centre h
should then be lowered a little, the cutter block c' brought into position
and the tackle hauled taut and fastened as before. The press is again
started and the shell is forced through the cutter block c', by which
means the projections left on the shell by the cutters d are cut away by
the cutters c. The same operation is repeated, for the third cutter
block c³, the cutters f of which smooth and finish the shell. The
guide bar o, shewn detached in Figure 10, serves to give the shell a
lateral motion corresponding with the centre line of the button's thereon
and the abutments of the cutters, by which means I obviate any incon-
venience from a ridge being left by the cutters in the case of. button
shells. When ribs are formed on the shell the ridges may easily be
taken off by a file.
When the hydraulio press is used instead of the screw press as
herein-before described, I prefer that the press should be arranged so as
to force the shell upwards instead of downwards. The screw press may

I
also be arranged to work in this direction or it may be placed hori
zontally.
It will be understood that the machinery herein-before described and
represented in the accompanying Drawing is applicable to plain shot and
shell of all kinds known under the name of conical shell and shot. To i
apply it to spiral lead coated and ribbed shot and shell other cutters
adapted to this peculiar form are substituted. For lead coated shot and
shell one or two cutter blocks only are required.
This Invention is also applicable for trucing up other plain metal
bodies, and also for cleaning out holes instead of boring them, in which 1
case the cutters must be arranged around the screw or ram as male
cuttors.
Having thus described the Invention communicated to me, and the
manner of performing the same, I wish it to be understood that I do not
.confine myself to the precise details herein laid down and shown in the ]
Drawing, but what I claim is,—
Firstly. The finishing conical shells and shot by forcing them
through a series of cutter blocks as herein-before described.
Secondly. The general arrangement and construction of machinery
or apparatus for the finishing of conical shells and shot as herein-before
described and represented in the accompanying Drawing.
In witness whereof, I, the said William Armand Gilbeo, have
hereunto set my hand and seal, this Twenty-first day of October
One thousand eight hundred and seventy-two.
