page_text: LETTERS PATENT to Jacob Henry Radcliffe, of Number 28, Waterloo
Street, in Oldham, in the County of Lancaster, Tin Plate Worker,
for the Invention of. " IMPROVEMENTS IN VALVE OIL CANS AND MACHINE
FOR MANUFACTURING THEM, WHICH IS APPLICABLE TO CUTTING OUT OF OTHER
CONE TIN OR SHEET-IRON VESSELS.”
Sealed the 30th October 1874, and dated the 2nd May 1874.
PROVISIONAL SPECIFICATION left by the said Jacob Henry Radcliffe
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd May. 1874.
I, JACOB HENRY RADCLIFFE, of Number 28, Waterloo Street, in
Oldham, in the County of Lancaster, Tin Plate Worker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN VALVE
OIL CANS AND MACHINE FOR MANUFACTURING THEM, WHICH IS APPLICABLE TO
CUTTING OUT OF OTHER CONE TIN OR SHEET-IRON VESSELS," to be as
follows:-
First. By constructing a steel wire spring in such a form and fixing
the spring inside the oil can for the purpose of opening and closing a

page_text: valve on or inside the oil can, which will dispose of all kinds of levers,
cross bars, and spiral springs connected with them, as hitherto used in
making valve oil cans. I make this spring of one length steel wire of
suitable strength and length as necessity requires for the size of oil can.
I bend this length of wire in the middle in the form of a hair pin; at
each end I form a number of rings, and forming a tangent on each end
of the wire on which I place two small tubes to affix the spring inside
the oil can.
I affix the valve pin and the thumb pin to above spring for
the purpose of opening and shutting the valve. By this means a better
cheaper mode and more durable can is manufactured.
The second part of my improvement consists of cutting out of sheet tin
cone-shaped bodies of oil cans or bodies of other cone-shape vessels, by
means of an ordinary circular cutter as hitherto used, with an addition
of a bracket for holding the segment of the cone plate, while the inner
circle of the cone or segment is cut by means of the circle cutters, by
which means all marking or scribening by templet is despensed with.
This part of my. Invention is applicable to cutting other vessels as cone-
shaped water buckets.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jacob Henry Radcliffe in the Great Seal Patent
Office on the 2nd November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACOB
HENRY RADCLIFFE, of No. 28, Waterloo Street, in Oldham, in the
County of Lancaster, Tin Plate Worker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of May, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Jacob Henry Radcliffe, Her special licence,
that I, the said Jacob Henry Radcliffe, my executors, administrators,
and assigns, or such others as I, the said Jacob Henry Radcliffe, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,

page_text: and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
VALVE OIL CANS AND MACHINE FOR MANUFACTURING THEM, WHICH IS APPLICABLE
TO CUTTING OUT OF OTHER CONE TIN OR SHEET-IRON VESSELS," upon the
condition (amongst others) that I, the said Jacob Henry Radcliffe, 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 Jacob Henry Radcliffe, do hereby
declare the nature of my said Invention, and in what manner the same.
is to be performed, to be particularly described and ascertained in and
by the following statement:-
I construct a steel wire spring of about sixteenth gauge of wire, cut
sixteen or twenty inches long, as necessity in the length and strength be
required, for various sizes of valve oil feeders. This wire I bend in the
form of a hair pin, as shewn, Fig. 8; on this wire I form several coils and
a tangent; on each end of the wire spring on these tangents I place a tube
of or small bend of tin; by this tube or bend I fix the spring firmly to
the sides of the oil feeds, as shown in section, Fig. 1; on the angle of this
spring K, Fig. 8, I fix the valve rod which is a length of wire flattened
at the end, and a coil turned on so that it will work easy when the coil
is closed on the spring; on this spring, Fig. 8, I place the piston Fig. 6,
by flattening the end and punching a small hole in it; then I place the
piston, Fig. 6, on to the angle K. I then form coils upon the spring,
leaving a tangent on each end of wire and fixed as above described.
On the end of the valve rod I solder a small brass cone, as shewn in the
oil feeders' spout, Fig. 1. I also place an ordinary common cork with a
hole, through in the spout, as shewn, et cetera; this tube may. be put in
any part of the spout so that when the piston T, Fig. 1, is pushed down.
the valve is opened outwards and closed again by the spring.
The second part of my Invention consists of certain arrangements
applied to an ordinary tin plate worker's circular cutting machine to
facilitate the cutting out of the body part of oil feeders the shape as
shown Fig. 2, or any other cone-shaped vessel, as iron water buckets,

page_text: without having to scribe them on sheets as in the usual mode in the iron
and tin plate trade.
Fig. 3 represents a sheet of tin or iron with nine bodies marked upon
it; in order to cut these segments out I cut the outer edge of each, No. 1,
2, 3, 4, 5, 6, 7, 8, and 9, by means of an ordinary circular cutting
machine used by tin plate workers. This plate is fixed to a bracket
at T, T, by means of two set screws fixed as an ordinary cutting machine
disk holder, and turns on a pivot at J on the bearing H; Lis a set screw
to fix the bearing bracket which has a slot in to allow the plate holder
to be set to its required position. The object is to allow the plate and
plate holder to move nearer the cutters, when each segment is cut off the
sheet, the centre pivot being fixed to give the same cut to each. This
sheet of tin or iron is fixed to a bracket at the lower edge by a clip and
two set screws at T, T; this bracket or clip is movable in a slot in another
bracket, so that on each cut being made on the sheet at S, S, S, the
sheet and bracket is moved together in the slot to the required distance
for each segment, and fixed by a bolt at a while each segment be cut;
this last-named bracket, with the slot in, is fixed by the set screw L to
another bracket which has a centre pivot for the sheet and bracket to
turn upon to give the same motion to each of the segments.
Fig. 4 shows the top of an ordinary guillotine cutting machine with a
segment upon it to have the angle ends cut off in radial line with the
outer edge of the segment; the guage B is the ordinary gauge which
slides parallel to the cutting edge represented by the dotted line; on the
edge of the guillotine cutting machine I make a slot for another guage D
to slide at right angles to the other guage, so that these, together with
edge of the top of the guillotine P forms the points of contact as a guide
to cut off each end of the segment E by turning over the sheet in radial
line with the outer edge of the segment, at this stage I get a segment as
shown Fig. 3, No. 2.
Fig. 5 shows the last-named segment upon a bracket or sheet holder
in the form of an angle with a pivot to turn upon to give the circular
motion to this bracket; this bracket I form by two bars a, a, and a
segment of sheet iron bolted upon them; on this segment I fix slotted
plates in radial line to hold the segment required to be cut; on its inner
edge I fix this bracket on the pivot and bolt, and bolt the segment B on the
angle bars, with the cutters inside the angle. I then place the segment

page_text: No. 3 in the slides C, and cut out the inner circle R, starting at the
point D; by this means I get the required segment for a cone-shaped oil
feeder or vessel, as iron bucket. The object of this part of my Invention
is to save labour by cutting out large quantities of segments by machines
instead of the usual mode of scribing and cutting by hand each segment
of tin or sheet iron for oil feeders or other cone-shaped vessels.
I claim the above mode of making valve oil feeders, and mode of
cutting them out, or other cone-shaped vessels.
In witness whereof, I, the said Jacob Henry Radcliffe, have here-
unto set my hand and seal, this Thirty-first day of October, in
the year of our Lord One thousand eight hundred and seventy-
four.
