Year: 1860

page_text: LETTERS PATENT to Timothy Whitby, of Milbank Street, Westminster,
and William Dempsey, of Great George Street, Westminster, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN APPLYING
led the 2nd April 1861, and dated the 10th October 1860.
PROVISIONAL SPECIFICATION left by the said Timothy Whitby and
William Dempsey at the Office of the Commissioners of Patents, with
their Petition, on the 10th October 1860.
We, TIMOTHY WHITBY, of Milbank Street, Westminster, and WILLIAM
DEMPSEY, of Great George Street, Westminster, in the County of Middlesex,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN APPLYING
SPRINGS TO RAILWAY TRUCKS, AND TO RAILWAY AND OTHER CARRIAGES," to be as
follows:-
This Invention has for its object improvements in applying springs to
railway trucks, and to railway and other carriages. For these purposes the
horns between which the brasses or bearings of the axles slide, in place of
being in a vertical position are fixed in an inclined position, and the springs
are arranged to act in a line parallel with the inclined direction of the horns.
The springs may be applied above or below the brasses or bearings of the
axles, or both above and below. The construction of springs which it is
preferred to employ in carrying out the Invention is such as are wound into
spiral and conical forms, but other constructions of springs may be used.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Timothy Whitby and William Dempsey in the Great Seal
Patent Office on the 10th April 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, TIMOTHY
WHITBY, of Milbank Street, Westminster, and WILLIAM Dempsey, of Great
George Street, Westminster, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of October, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Timothy Whitby and William Dempsey, Her special licence that we, the
said Timothy Whitby and William Dempsey, our executors, administrators,
and assigns, or such others as we, the said Timothy Whitby and William
Dempsey, 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
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPLYING
SPRINGS TO RAILWAY TRUCKS, AND TO RAILWAY AND OTHER CARRIAGES," upon
the condition (amongst others) that we, the said Timothy Whitby and William
Dempsey, our executors or administrators, by an instrument in writing under
our, or their hands and seals, or under the hand and seal of one of us or them,
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 Timothy Whitby and William
Dempsey, 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 :-
This Invention has for its object improvements in applying springs to
railway trucks, and to railway and other carriages. For these purposes the
horns between which the brasses or bearings of the axles slide, in place of
being in a vertical position are fixed in an inclined position, and the springs
are arranged to act in a line parallel with the inclined direction of the horns.
The springs may be applied above or below the brasses or bearings of the
axles, or both above and below. The construction of springs which it is

page_text: preferred to employ in carrying out the Invention, is such as are wound into
spiral and conical forms, but other constructions of springs may be used.
Having thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side elevation of part of a railway truck having springs
applied according to our Invention, the springs being above the brasses or
bearings; and Figure 2 shews a side elevation of part of a railway truck
having springs applied thereto according to our Invention, the springs being
below the bearings or brasses.
a, a, are the horns which receive the brasses or bearings b, b, of the axles,
and between which such brasses or bearings slide, and are guided as they move
up and down. These horns are inclined, as shewn, and the springs used
(whatever be their form or material) are caused to act in a line parallel with
such inclined horns, as is clearly shewn by the Drawing. It is preferred to
employ spirally wound conical springs, such as shewn in the Drawing, but
other forms of springs, whether of steel, vulcanized india-rubber, or of other
material may be employed, so long as they are applied in combination with
inclined horns, and are arranged to act in a line parallel with the inclined
horns used with them. The Drawings simply show the Invention applied to
railway trucks, but a machinist and carriage builder will, aided by the
description and Drawings, readily apply springs according to our Invention to
railway and other carriages.
In witness whereof, we, the said Timothy Whitby and William Dempsey,
have hereunto set our hands and seals, this Fifth day of April, in the
year of our Lord One thousand eight hundred and sixty-one.
TIMOTHY WHITBY.
