Year: 1873

page_text: LETTERS PATENT to James Partridge, of the Firm of James Partridge
and Company, of the Phoenix Works, Brewer Street, Smethwick,
in the County of Stafford, Coach Axles Manufacturers, for the
Invention of "IMPROVED MEANS OF AND APPLIANCE FOR PREVENTING
CARRIAGE AND OTHER WHEELS LEAVING THE AXLES IN CASES OF BREAKAGE OR
FROM OTHER Causes.”
Scaled the 23rd December 1873, and dated the 27th June 1873.
PROVISIONAL SPECIFICATION left by the said James Partridge at
the Office of the Commissioners of Patents, with his Petition, on
the 27th June 1873.
I, JAMES PARTRIDGE, of the Firm of James Partridge and Company,
of the Phoenix Works, Brewer Street, Smethwick, in the County of
Stafford, Coach Axles Manufacturers, do hereby declare the nature of
the said Invention for "IMPROVED MEANS OF AND APPLIANCE FOR PREVENTING
CARRIAGE AND OTHER WHEELS LEAVING THE AXLES IN CASES OF BREAKAGE OR FROM
OTHER CAUSES," to be as follows:-
The object of this Invention is to prevent a wheel leaving the axle

page_text: in cases of breakage or other cause, and for retaining the wheel in
position after the loss of the end cap or cup.
The Invention is based upon a previous Patent granted to Ebenezer
Partridge on the 17th day of June, 1870, number 1747, and assigned to
me on the Third day of March 1871.
In the Specification of that Patent a double pronged appliance is
described as acting in an annular groove upon the axle box, the two
prongs being attached by a springy strap or band. Now it has been
found in practice that the double pronged appliance was very unhandy
to fit into position and to be removed, that it often became deranged
from the rotation of the wheel; also from the positions which the
prongs occupied that unnecessary strain was put upon them.
According to my present Invention I dispense with the double pronged
appliance and also with the apertures through which they passed, and
employ a strap curved or shaped to fit a segment of the annular groove,
so that a much longer and more secure bearing is obtained.
•
The strap is upon the upper portion of the groove, and has a threaded
pin or stud upon it which is slid into position in first putting the wheel
in place, and finds itself in an aperture on the axle collar, where it is
held in place by a nut in a rigid manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Partridge in the Great Seal Patent Office
on the 27th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
PARTRIDGE, of the Firm of James Partridge and Company, of the
Phoenix Works, Brewery Street, Smethwick, in the County of Stafford,
Coach Axles Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of June, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Partridge, Her special licence that

page_text: I, the said James Partridge, my executors, administrators, and assigns,
or such others as I, the said James Partridge, my executors, adminis-
trators, 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 "IMPROVED MEANS OF AND APPLIANCE FOR PRE-
VENTING CARRIAGE AND OTHER WHEELS LEAVING THE AXLES IN CASES OF BREAKAGE
OR FROM OTHER CAUSES," upon the condition (amongst others) that I, the
said James Partridge, 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 calender months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Partridge, 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 thereof, reference being had to the Drawings
hereunto annexed, that is to say:
―:
The object of this Invention is to prevent a wheel leaving the axle in
cases of breakage or other cause, and for retaining the wheel in position
after the loss of the end cap or cup.
The Invention is based upon a previous Patent granted to Ebenezer
Partridge on the 17th day of June 1870, No. 1747, and assigned to me
on the 3rd day of March 1871.
In the Specification of that Patent a double pronged appliance is
described as acting in an annular groove upon the axle box, the two
prongs being attached by a springy strap or band. Now it has been
found in practice that the double pronged appliance was very unhandy
to fit into position and to be removed, that it often became deranged
from the rotation of the wheel; also from the position which the prongs
occupied that unnecessary strain was put upon them.
According to my present Invention I dispense with the double pronged
appliance, and also with the apertures through which they passed, and
employ a saddle strap a curved or shaped as in Figure 1 of the Drawings,

page_text: to fit a segment of the annular groove 6 of the nave box c, Figure 2, so
that a much longer and a more secure bearing is obtained.
The strap a rests upon the upper segment or portion of the groove, as
in Figure 3, and has a pin or stud d preferably threaded upon it, which is
slid into position in first putting the wheel in place, and finds itself in an
aperture e on the axle collar f, Figure 4, where it is held in place by a
nut g, Figure 5, in a rigid manner.
.
The nut has a reduced portion at its lower part to fit into the aperture e,
and its shoulder / bears upon the collarf when it is screwed home, a
swivel or split pin i being passed into a transverse hole in the head of 1
the nut and the pin or stud d, as shown in Figure 5, to prevent the nut
working loose during the running of the wheel.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
The employment of a saddle strap within the annular groove of a 1
wheel or axle box, as and for the purpose set forth and shown.
Secondly. I claim the means of adjusting and retaining the saddle
strap in the groove of an axle box; also the appliances in combination
with such strap for preventing the nut working loose as described and
shown.
In witness whereof, I, the said James Partridge, have hereunto
set my hand and seal. Twenty-sixth day of December. One
