IMPROVEMENTS IN PRESSES FOR BLOCKING THE TYRES OF RAILWAY AND OTHER WHEELS
Year: 1865

page_text: LETTERS PATENT to William Holiday, of the Union Foundry, Bradford,
in the County of York, Engineer, for the Invention of "IMPROVEMENTS IN
PRESSES FOR BLOCKING THE TYRES OF RAILWAY AND OTHER WHEELS."
Sealed the 25th August 1865, and dated the 1st March 1865.
PROVISIONAL SPECIFICATION left by the said William Holiday at tho
Office of the Commissioners of Patents, with his Petition, on the 1st
March 1865.
I, WILLIAM HOLIDAY, of the Union Foundry, Bradford, in the County of
York, Engineer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN PRESSES FOR BLOCKING THE TYRES OF RAILWAY AND OTHER WHEELS,"
to be as follows:-
The improvements relate to the application of steam to presses for blocking
the tyres of railway and other wheels. The tyre to be blocked is placed on a
plate supported by or forming part of the bed plate of the press; and this plate
is for this purpose formed true to one side surface of the tyre, the other side
surface of which is acted upon by a corresponding plate connected to the
piston, or it may be to the steam cylinder to receive the force of the steam as
admitted by suitable valvular arrangement in the direction and to the extent
desired.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Holiday in the Great Seal Patent Office on the 31st
August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOLIDAY, of the Union Foundry, Bradford, in the County of York, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Holiday,. Her special licence that I, the said William Holiday, my
executors, administrators, and assigns, or such others as I, the said William
Holiday, 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, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN PRESSES
FOR BLOCKING THE TYRES OF RAILWAY AND OTHER WHEELS," upon the condition
(amongst others) that I, the said William Holiday, my executors or adminis-
trators, 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 inanner 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 Holiday, 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 thereof, that is to say:
The improvements relate to the application of steam to presses for blocking
the tujeres of railway and other wheels:
But that the Invention may be better understood I will by the aid of the
accompanying Drawings proceed to describe means pursued by me.
DESCRIPTION OF THE DRAWINGS.
C.
Figure 1 shews a front view; Figure 2 a side view; and Figure 3 a. vertical
section of apparatus constructed according to my Invention; Figures 4 and 5
shew horizontal sections of the same taken through the lines A, B, and C, D.

page_text: In each of these Figures the same letters indicate corresponding parts wherever
they occur.
a, a, is the bottom or bed plate, the upper-surface of which is formed true
to receive the tyre placed thereon to be pressed; 6 represents a heated tyre on
this bed plate in position for being blocked. For the purpose of blocking or
compressing, the opposite surface of the tyre is acted upon by the under surface
of the moveable plate c, and this plate, according to the arrangement shewn,
is connected by the rod d to the piston e, with capability of movement to and
fro as acted upon by steam in the cylinder f. Steam from a suitable boiler is
admitted to the upper or under surface of the piston e, by the valve g, in the
valve box h, through the passages i, i. j is the passage for the steam from
the boiler into the valve box h, and k is the outlet passage for the spent steam.
The valve g is connected to the spindle g), which passes through the stuffing
box h, and at its opposite end is formed with a loop g³, to receive the outer end
of an arm affixed to the axis m, which turns in suitable bearings, and has
affixed to it the lever arm m¹, which at its end m³ is formed into a handle by
which the attendant regulates the passage of steam into the cylinder f to either
side of the piston e, or keeps it shut off therefrom. Upon the bed a I apply
the segments n, n, n, and these at n¹ are each formed to receive the conical
pin o, projecting from the under surface of the plate c in such manner that
when by the force of the steam acting on the upper surface of the piston e, or
by the steam being allowed to escape from the under surface of that piston,
the under surface of the plate c comes upon a tyre placed as indicated on the
bed plate a, to give truth to the opposite surfaces of a tyre, the conical pin o
will at the same time act on the surfaces n¹ of the segments n to force those
segments outwards when their outer surfaces or periphery will press against
and give truth to the inner surface, and to the rim of the tyre under
operation. The cylinder f is formed with lugs f¹ to receive the necks formed
at one end of the rods f, whilst the necks at the other ends of these
rods are received into other lugs a' on the bed plate a, by which means
the cylinder and bed plate are held together. These necks are held in
their respective lugs by the set screws acting on the covers f³ and a³.
Having thus described my improvements and means which I adopt in
carrying the same into effect, I would have it understood that I do not confine
myself to the precise details shewn and described, as these may be varied
without departing from the peculiar character of my Invention, and in some
cases in place of the rod from the plate c being connected to a moveable piston
it may be connected to a cylinder moveable on a stationary piston, but what
I do claim is the adaptation or combination of means whereby steam is

stantially as described.
In witness whereof, I, the said William Holiday, have hereunto set
my hand and seal, this Thirtieth day of August, in the year of our Lord
One thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
within-named William Holiday, in
the presence of

Clerk to E. A. Barret,
