IMPROVEMENTS APPLICABLE TO AXLES OF ENGINES AND CARRIAGES FOR RAILWAYS AND OTHER ROADE
Year: 1867

page_text: PROVISIONAL SPECIFICATION left by the said George Buxton and
Samuel Bann at the Office of the Commissioners of Patents, with their
Petition, on the 14th August 1867.
We, GEORGE BUXTON, of Fenton, in the County of Stafford, Engineer, and
SAMUEL BANN, of Crewe, in the County of Chester, Mechanical Draftsman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS APPLICABLE
TO AXLES OF ENGINES AND CARRIAGES FOR RAILWAYS AND OTHER ROADE," to be as
follows:-
Our Invention consists in mounting axles so that the blocks which carry
them shall independently of their usual vertical-motion-be-capable of swivelling
upon centres. To accomplish this.we propose to provide the said blocks and
which carry the brasses with studs.constituting centres-of-motion mounted in
the usual parts, which slide in the ordinary guides attached to the carriage, by
which means the axle while running in bearings as usual is also capable of

of motion. The springs employed may be similar to those in common use,
but we propose to use springs of a spiral form.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Buxton and Samuel Bann in the Great Seal Patent
Office on the 14th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
BUXTON, of Fenton, in the County of Stafford, Engineer, and SAMUEL BANN,
of Crewe, in the County of Chester, Mechanical Draftsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-seven, and thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said George Buxton and Samuel Bann, Her special license that we,
the said George Buxton and Samuel Bann, our executors, administrators, and
assigns, or such others as we, the said George Buxton and Samuel Bann, 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 APPLICABLE TO THE AXLES OF ENGINES
AND CARRIAGES OF RAILWAYS AND OTHER ROADS," upon the condition, amongst
others, that we, the said George Buxton and Samuel Bann, by an instrument
in writing under our hands and seals (or under the hand and seal of one of
us), should particularly describe and ascertain the nature of the said Inven-
tion, 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 George Buxton, 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 and accompanying Drawings, that is to say:-
Our Invention consists in mounting axles of engines and carriages of rail-
ways and other roads so that the blocks which carry them shall independently
of their usual vertical motion be capable of swivelling upon centres, so that
if one side of the engine or carriage become more elevated than the other

page_text: the axle by turning upon centres of motion will accommodate itself to such
position without a strain being put thereon.
In the accompanying Drawing Fig. 1 represents a railway axle and its
appendages in side elevation, one half thereof being shewn in section; Fig. 2
is a cross section thereof; and Fig. 3 a plan view also in section.
At a is an ordinary railway wheel, mounted as usual upon the axis b; this
axis runs in a bush e formed in two parts, and carried by the block d, which
would according to the usual arrangement be capable of sliding upward and
downward in the born plate e; but according to our Invention the said
block d is provided with projecting studs f mounted in brasses g, which are
confined by flanges to the horn plate e, and are capable of sliding therein
vertically; the said brasses therefore occupy the place of the usual sliding
block, they being caused to move upward or downward through the medium
of the studs. Supposing the engine or carriage to be running equally loaded
and upon straight level lines the action will be precisely the same as in ordinary
axles, but should one side thereof become higher than the other then instead
of a strain being put upon the axle it will swivel upon the centres of motion f
and as both ends of the axle are mounted in a similar manner a compensation
will be effected for the necessary turning of the axle at right angles to the
engine or carriage. In the Drawing I have shewn spiral spring h applied
to the sliding block, but the more ordinary bar spring may be adopted if
desired. I have also shewn a revolving finger i attached to the axle, and
which supplies lubricating material from the chamber k, but the usual grease
box may be adopted.
Having thus described and ascertained the nature of our said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that we claim as secured to us under the above in part recited Letters
Patent, mounting the axles of engines and carriages for railways and other roads
so that they shall independently of their usual vertical motion be capable of
swivelling upon centres after the manner above described.
In witness whereof, I, the said George Buxton, have hereunto set my
hand and seal, this Thirteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-eight.
GEORGE BUXTON.-(L.S.)
