A CERTAIN H IMPROVEMENT IN THE MANUFACTURE OF RADWAY AT AND OTHER WHEELS.
Year: 1872

page_text: LETTERS PATENT to James Murphy, of Newport, in the County of
Monmouth, Civil Engineer, for the Invention of "A CERTAIN
H
IMPROVEMENT IN THE MANUFACTURE OF RADWAY
AT AND OTHER
WHEELS.
"
PROVISIONAL SPECIFICATION left by the said James Murphy at the
Office of the Commissioners of Patents, with his Petition, on the
6th September 1872.
I, JAMES MURPHY, of Newport, in the County of Monmouth, Civil
Engineer, do hereby declare the nature of the said Invention for
"A CERTAIN IMPROVEMENT IN THE MANUFACTURE OF RAILWAY AND OTHER
WHEELS," to be as follows:-
My improvement consists in inserting in each space, spaces, or
junctions where wheel spokes abut each other on the outside periphery
of the wheel, a glut or V piece or pieces, which being heated simul-
taneously and in conjunction with the periphery of the wheel are rolled,
pressed, hammered, or welded in their several places by machinery
consisting of furnaces, bed plates, centre pins, screws, wheels, rollers, and
other mechanical appliances.

page_text: The periphery of the wheel, being iron or other material, after under-
going the whole or part of these processes, will be formed truo in
circumference and ready to receive a tyre with or without turning.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Murphy in the Great Scal Patent Office
on the 4th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MURPHY, of Newport, in the County of Monmouth, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of September, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Murphy, Her special licence
that I, the said James Murphy, my executors, administrators, and
assigns, or such others as I, the said James Murphy, 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, excrcise,
and vend, within the United Kingdom of Great Britain and Ircland,
the Channel Islands, and Isle of Man, an Invention for "A CERTAIN
IMPROVEMENT IN THE MANUFACTURE OF RAILWAY AND OTHER WHEELS," upon the
condition (amongst others that I, the said James Murphy, 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 James Murphy, 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 :-
-
My improvement in the manufacture of railway and other wheels con-
sists in inserting in each space, spaces, or junctions where wheel spokes

page_text: abut each other on the outside periphery of the wheel, a glut or V piece
or pieces, which being heated simultaneously and in conjunction with
the periphery of the wheel, are rolled, pressed, or welded in their.
several places by machinery consisting of furnaces, bed plates, center
pins, screws, wheels, rollers, and other mechanical appliances.
The periphery of the wheel, being iron or other material, after under-
going the whole or part of these processes will be formed true in circum-
ference and ready to receive a tyre, with or without turning.
On the accompanying Sheet of Drawing Figure 1 is a sectional
elevation of a machine by means of which my improved manufacture
may be performed, and Figure 2 is a plan view of same.
A, bed plate; B, rollers for compressing gluts and periphery of wheel
centre; C¹, C2, C3, sliding blocks carrying rollers B1, B2, B³; D, revolving
plate and driver carrying wheel centre; E, centre stud and vertical
shaft; F, wheel centre with gluts finserted; G, bevel wheel on centre
stud; H, bevel pinion gearing into stud wheel G; I, step block and
bearing J, coupling wheels for working up screws; K, adjusting screw
to take up wear in step; L, main shaft; M, screws for working up
rollers; N, counter shaft for running cutter blocks at high speeds for
rounding wood centres;. O, pulley on shaft N; P, strap driving revolving
block C when cutter blocks are applied thereto.
The gluts fhaving been inserted in the periphery of the wheel centre
F, in an ordinary circular fire, the wheel centre is withdrawn from the
fire at a suitable heat and placed on the vertical shaft E, which by means
of the shaft L and bevel gearing H, G, is then set revolving, carrying
with it the wheel centre F, and the gluts are thus brought into contact
with the rollers B', B*, B³, (previously adjusted to the required diameter
by the screws M,) whereby the gluts are pressed and welded in their
respective positions, and the outer periphery of the wheel centre being
rounded at the same time a perfectly true circumference is obtained
ready to receive the tyre.
It will be evident that the outer periphery of a wheel centre to which
no gluts have been applied may be made true in circumference by the
same operation.
Further, by removing the roller blocks B', B2, B³, and substituting in
the position of C³ a block with cutters, and driving these cutters by

page_text: means of the strap P in an opposite direction to the wheel centre acted
upon, I may cut the outer periphery of wood centres to a true circum-
ference.
I have shown three compression rollers, but any number may be used,
according to requirement.
Having now described and ascertained the nature of my said Invention
and in what manner the same is or may be performed, I desire it to be
understood that although I find the machine herein-before described and
illustrated on the accompanying Drawing very suitable for effecting my
object, I do not purpose limiting myself exclusively thereto as the
simultaneous welding of the gluts in their places, and rounding of the
outer periphery of the wheel centre might be effected by other combina-
tions of mechanism, and that what I claim as secured to me by the
herein-before in part recited Letters Patent is,-
Firstly. The use of the method of welding gluts and obtaining a truc
circumference on the outer periphery of the centres of railway and other
wheels, substantially as herein-before set forth.
Secondly. The use of the machine herein-before described and illus-
trated on the accompanying Drawing, substantially as and for the
purposes herein-before set forth.
In witness whereof, I, the said James Murphy have hereunto set
my hand and seal, this Third day of March, in the year of our
Lord One thousand eight hundred and seventy-three.
