Year: 1855

page_text: LETTERS PATENT to Frederick William Mowbray, of Shipley, near Leeds,
in the County of York, Engineer, for the Invention of "IMPROVEMENTS IN
BEARINGS FOR THE AXLES OF RAILWAY WHEELS AND OF OTHER AXLES OR SHAFTS,
WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO AXLES OR SHAFTS AND OTHER
LIKE RUBBING SURFACES."
Sealed the 10th September 1855, and dated the 29th March 1855.
PROVISIONAL SPECIFICATION left by the said Frederick William Mow-
bray at the Office of the Commissioners of Patents, with his Petition, on
the 29th March 1855.
I, FREDERICK WILLIAM MOWBRAY, of Shipley, near Leeds, in the County of
York, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BEARINGS FOR THE AXLES OF RAILWAY WHEELS AND OF OTHER
AXLES OR SHAFTS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO AXLES OR SHAFTS
AND OTHER LIKE RUBBING SURFACES," to be as follows:-
The improvements consist in forming the bearings for axles of railway
wheels and of other axles or shafts with the rubbing surface grooved or
recessed in an oblique direction to the axles or shafts working in them,. for

page_text: the
purpose of more uniformly distributing the oil or other lubricating matter,
and thus keeping the parts cool. I also form such oblique grooves in the
rubbing surfaces of axles or shafts and other like rubbing surfaces.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick William Mowbray in the Great Seal Patent Office
on the 29th September 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WILLIAM MOWBRAY, of Shipley, near Leeds, in the County of York, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of March, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick William Mowbray, Her special licence that I, the said
Frederick William Mowbray, my executors, administrators, and assigns, or
such others as I, the said Frederick William Mowbray, 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 BEARINGS FOR THE AXLES
OF RAILWAY WHEELS AND OF OTHER AXLES OR SHAFTS, WHICH IMPROVEMENTS ARE
ALSO APPLICABLE TO AXLES OR SHAFTS AND OTHER LIKE RUBBING SURFACES," upon
the condition (amongst others) that I, the said. Frederick William Mowbray,
by an instrument in writing under my hand and seal, 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 Frederick William Mowbray, 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 consist in forming the bearings for axles of railway

page_text: wheels and of other axles or shafts with the-rubbing surface grooved or
recessed in an oblique direction to the axles or shafts working in them, for the
purpose of more uniformly distributing the oil. or other lubricating matter, and
thus keeping the parts cool. I also form such oblique grooves in the rubbing
surfaces of axles or shafts and other like rubbing surfaces.
But that the nature of my said Invention, and the means which I adopt in
carrying the same into effect may be fully understood, I will proceed to describe
the Drawing annexed.
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 show a plan and end view of a form of bearing suitable
for a railway axle with a recess or groove formed therein, according to my
improvements, in an oblique direction, extending from one end thereof to
the other.
Figure 3 shows a plan; and Figures 4 and 5 two sectional views, of a step
or bearing for a vertical shaft. a, a, is the groove or recess, formed in an
oblique direction around the cylindrical surface of the step, which receives
the foot of the shaft.
Figure 6 shows a plan, and Figures 7 and 8 two sectional views, of another
form of bearing with the groove formed therein continuous, but in an oblique
direction.
Figures 9 and 10 show two forms of shafts suitable for railway or other
axles with similar grooves formed upon its rubbing surface in an oblique
direction.
Figure 11 shows the lower end of a vertical shaft with a similar groove
formed around it.
It will be seen that in each case the oblique grooves or recesses are formed
in the rubbing surfaces, and it will be found that with the parts thus formed
the oil or other lubricating matter employed will be more uniformly distributed
and thereby kept from heating.
Having thus described the nature of my said Invention, and the means
which I adopt in carrying the same into practice, I would have it understood
that I do not confine myself to the precise details shown and described, as
variations may be made without departing from the peculiar character of my
improvements, and an intelligent workman from the illustrations given will
readily make such variations needed in adapting the grooves to the particular
form of, bearing, or axle, or other rubbing surface required; but what I do claim
is, the forming bearings for axles or shafts of railway wheels and of other

page_text: axles or shafts, as also the rubbing surfaces of axles or shafts and other like
rubbing surfaces, with grooves or recesses formed therein in an oblique
direction, for the purpose of more effectually distributing the oil or other
lubricating matter employed, as explained.
In witness whereof, I, the said Frederick William Mowbray, have
hereunto set my hand and seal, this Twenty-seventh day of September,
in the year of our Lord One thousand eight hundred and fifty-five.
FREDERICK WILLIAM MOWBRAY. (L.B.)
