IMPROVEMENTS IN THE CONSTRUCTION OF WHEEL-MOULDING MACHINES
Year: 1867

page_text: LETTERS PATENT to Joseph Willcock, of Stockport, County of Chester,
Engineer, and Samuel Mason, junior, of Manchester, County of Lan-
caster, Engineer, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF WHEEL-MOULDING MACHINES."
Sealed the 6th September 1867, and dated the 13th March 1867.
PROVISIONAL SPECIFICATION left by the said Joseph Willock and
Samuel Mason at the Office of the Commissioners of Patents, with their
Petition, on the 13th March 1867.
We, JOSEPH WILLCOCK, of Stockport, County of Chester, Engineer, and
SAMUEL MASON, junior, of Manchester, County of Lancaster, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF WHEEL-MOULDING MACHINES," to be as follows:-
These improvements relate to the wheel-moulding machines, by means of
which wheels or pulleys and other like articles can be moulded with a section
or segment of a pattern held in an arm that can be turned upon an axis as
each section or segment is moulded, and thus complete the wheel; the extent
of motion for moulding toothed wheels being regulated by suitable change and
dividing gear, as used in wheel-cutting engines or machines.

page_text: These improvements consist in attaching the arm carrying the said section
or segment to a radial arm similar to that of a radial drilling machine, upon
which is also fixed the usual change and dividing wheels used in wheel-
moulding machines, the radial arm being constructed to turn upon a fixed
column as an axis, by these means when a wheel has been moulded the arm
carrying the moulding machine with it can be turned aside and another
commenced
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Willcock and Samuel Mason in the Great Seal Patent
Office on the 12th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
WILLCOCK, of Stockport, County of Cheshire, Engineer, and SAMUEL MASON,
junior, of Manchester, Count of Lancaster, Engineer, send greeting.
WHEREAS Her mos
.ellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the airteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Joseph Willcock and Samuel Mason, junior, Her special licence that we,
the said Joseph Willcock and Samuel Mason, junior, our executors, adminis-
trators, and assigns, or such others as we, the said Joseph Willcock and Samuel
Mason, junior, our 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, and
yend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF WHEEL-MOULDING MACHINES," upon the condition (amongst others) that we, the
said Joseph Willcock and Samuel Mason, junior, our executors or administrators,
by an instrument in writing under our, 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 we, the said Joseph Willcock and Samuel Mason,
junior, do hereby declare the nature of our 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

page_text: accompanying Drawings, and to the letters and figures marked thereon, that
is to say:--
These improvements relate to the machines at present used.for moulding.
wheels, pulleys, and other like articles from a section pattern, that is, a short.
segment which is held in a suitable arm that can be made to revolve
round an axis, the supposed centre of a wheel, pulley, or other like article,
as the section is moulded.
Our improvements consist in attaching the said arm to a radial arm or
fixing similar to that of a drilling machine, which arm also carries the whole
of the usual change and dividing wheels, this radial arm or fixing being so
arranged as to turn upon a fixed pillar as a centre; by these means when one
wheel has been moulded the machine can be easily turned round the fixed
pillar and another wheel commenced without deranging the working parts of
the machine.
That our Invention may be properly understood we will proceed to describe
the Drawings hereunto annexed and forming part of our Specification.
Fig. 1 is a front elevation of a moulding machine constructed according to
our Invention; Fig. 2 is a side elevation of the same. In each of the above
Figures the same letters of reference indicate like parts.
A is the section pattern or segment of a bevel wheel usually employed in
these machines for moulding bevel wheels; the segment A is held in a foot
at the end of a spindle B which is secured to the slide C. The slide C and
consequently the segment A can be raised or lowered on a slide suitably
arranged on the fixing H by means of the handle wheel D, worm and wheel
G and F, and rack and pinion E and V, the rack V being fixed to the frame
or fixing H, constituting a motion similar to that often used in drilling
machines. The frame H slides in another frame X which is fixed upon a
spindle J, supported by the the radial arm M. The distance from the centre of
the spindle J to the pitch line on the teeth of segment pattern A would be the
radius of the wheel to be moulded, which can be increased or decreased by
turning the band wheel R to the right or left, as the hand wheel R is fixed
to X. K is the ordinary dividing wheel used in wheel-cutting machines, and
is made to revolve by means of a worm and change gear in a similar manner
to that employed in such machines by means of the handle P. The radial
arm M is supported by the pillar N, which may be secured at the top to the
walls of the foundry, and at the bottom upon a stone fixed in the floor of the
foundry, or may be secured at the bottom only. The radial arm M is free to
move round the column, except when a wheel is moulding, it is then secured
by means of a cap Y, which is tightened by bolts or other suitable contrivance
to the pillar.

page_text: It will be seen from the foregoing description that wheels can be moulded
all round the pillar N within the radius from centre of pillar N to centre of
a spindle J. L is a casting for holding a spindle to which an ordinary trammel
may be attached for making a flat surface or shape required for moulding the
wheel upon the sand. Ordinary moulding boxes may also be used, both
bottom and top. The spindle J has a conical bearing in M so as to always
keep it central and without any slack or play.
In witness whereof, we, the said Joseph Willcock and Samuel Mason,
junior, bave hereunto set our hands and seals, this Thirty-first day of
August, in the year of our Lord One thousand eight hundred and
sixty-seven.
