Year: 1866

page_text: LETTERS PATENT to James Samuel Cooke, of Abingdon Street, in the
City of Westminster, Civil Engineer, for the Invention of "IMPROVE
MENTS IN AXLE BOXES." -A communication from abroad by Joseph Green
Cooke, of Vera Cruz, Mexico.
PROVISIONAL SPECIFICATION left by the said James Samuel Cooke
at the Office of the Commissioners of Patents, with his Petition, on the
8th November 1866.
I, JAMES SAMUEL COOKE, of Abingdon Street, in the City of Westminster,
5 Civil Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN AXLE BOXES," to be as follows:-
This Invention relates, firstly, to the construction and to the mode of fitting
as hereafter described of a stuffing box round the neck or inside shoulder. of
the axle adjoining the journal.
Secondly, to a combination of parts of axle boxes as hereafter described,
whereby the weight of the wagon or carriage is transmitted directly from the
spring to the axle without putting weight on the axle box,-and whereby.the
journal and brass are kept efficiently lubricated.
Thirdly, to the employment, as hereafter described, of a layer or packing of
india-rubber.or other suitable yielding material above the brass, for the
'purpose of equalizing the pressure upon the whole top:surface of the brass.

page_text: The stuffing box is constructed and fitted as follows:-Around the neck or
inside shoulder of the axle adjoining the journal I fit a metal ring turned to
fit into a circular recess formed in the axle box to receive it; between this
ring and the neck or shoulder of the axle I fit a packing of india-rubber or
other suitable material which prevents the oil escaping at that part; screws
which pass from the front of the axle box to the ring press it against the
packing; the screws may be fixed in place by chock nuts, which will also
prevent the oil leaking out at the points where the screws pass through. The
combination of parts of axle boxes as before referred to is as follows:-
The axle box is cast open at the top to allow the brass which bears upon the
journal to be dropped in; above the brass a layer or packing of india-rubber
or other suitable yielding material is introduced, and then a cast-iron or other
metal plate is placed in the top of the box above this packing. The weight
of the wagon or carriage is borne by the plate and the packing, which latter
in transmitting it to the brass and axle equalizes the pressure upon the whole
top surface of the brass, this packing at the same time prevents the escape of
any oil which may be pumped up by the jolting of the wagon. The outer
end or shoulder of the axle has a slight bearing upon the box to keep the
box straight and take the sag of the stuffing box. By removing the wagon
spring the brass as well as the packing and the plate above it, can be taken
out and examined, and at the same time the oil in the box can be seen and
its level ascertained. The bottom of the axle box is formed with an aperture
kept closed by a plug for drawing off the oil when necessary. The oil may
be supplied to the axle box before the brass is put in place, or it may be
admitted by an inlet provided with a screw plug.
The Invention consists, lastly, in constructing brasses for journals hollow,
and they may then be used as an oil reservoir, one or more apertures being
formed in the bottom of the brass to allow the oil to escape...:.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Samuel Cooke in the Great Seal Patent Office on the s
8th May 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
SAMUEL COOKE, of Abingdon Street, in the City of Westminster, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters St
Patent, bearing date the Eighth day of November, in the year of our Lord

page_text: One thousand eight hundred and sixty-six," in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Samuel Cooke, Her-special licence that I; the said James
Samuel. Cooke, my executors, administrators, and assigns, or such others
as: I, the said James Samuel Cooke, 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 AXLE BOXES," (communicated to me from
abroad by Joseph Green Cooke, of Vera Cruz, Mexico,) upon the condition
(amongst others) that I, the said James Samuel Cooke, 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
calendar months' next and immediately after the date of the said Letter's
Patent.

...
NOW KNOW YE, that I, the said James Samuel Cooke, 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, reference being had to the Drawings hereunto
annexed, that is to say:
This Invention relates,, firstly, to the construction and to the mode of fitting.
as hereafter described of a stuffing box round the neck or inside shoulder of
the axle adjoining the journal.
Secondly; to a combination of parts of axle boxes as hereafter described
whereby the weight of the wagon or carriage is transmitted directly from the
spring, to the axle without putting weight on the axle box, and whereby
the journal and brass' are 'képt efficiently lubricated.
Thirdly, to the employment as hereafter described of a layer or packing
of india-rubber or other suitable yielding material above the brass for the
purpose of equalizing the pressure upon the whole top surface of the brass.
.
Figure. of the annexed Drawings is a longitudinal section; Figure 2 a
plan, and Figure 3 an end elevation, one half in section, of an axle box
constructed according to my improvements. A is the axle box or casing;
C, the axle; and. D, the journal.
The stuffing box before referred to is constructed and fitted as follows:-.
Around the neck or inside shoulder of the axle C adjoining the journal D

page_text: I fit a metal ring B turned to fit into a circular fecess formed in the axlè
box A to receive it; between this ring B and the neck or shoulder of the
axle C I fit a packing J of india-rubber or other suitable material which
prevents the oil escaping at that part isérews: HH,which pass from the
front of the axle box to the ring B.press it against the packing J the
screws H, H, may be fixed in place, by chock nuts, as shown, which will also
prevent the oil leaking out at the points where the screws pass through. The
combination of parts of axle boxes as before referred to is as follows:-The
axle box A is cast open at the top to allow the brass E. which bears upon
the journal D to be dropped in, above the brass a layer or packing N of
india-rubber or other suitable yielding material is introduced, and then a
cast iron or other metal plate F is placed in the top of the box above this
packing. The weight of the wagon or carriage is borne by the plate F and
the packing N, which latter in transmitting it to the brass E and ȧxle D
equalizes the pressure upon the whole top surface of the brass,. this packing N
at the same time prevents the escape of any oil, which may be pumped up by
the jolting of the wagon: The outer end or shoulder of the axle has a slight
bearing upon the box at K to keep the box straight and take the sag of the
stuffing box. By removing the wagon spring G the brass E as well as
the packing N and the plate F above it can be taken out and examined, and
at the same time the oil in the box can be seen, and its level ascertained.
The bottom of the axle box is formed with an aperture kept closed by a plug P
for drawing off the oil when necessary. The oil may be supplied to the
axle box before the brass is put in place, or it may be admitted by an inlet
provided with a screw plug L.
The Invention consists, lastly, in constructing brasses for journals hollow
as shown, and they may then be used as an oil reservoir, one or more apertures
being formed in the bottom of the brass to allow the oil to escape. M, M, are
guides for the horn plates. The construction of axle boxes with the top open
to allow the brass to be dropped in forms no part of this Invention, except
when used in combination with the packing N, and plate F.
"
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,
First, the construction of and mode of fitting a stuffing box round the neck
or inside shoulder of the axle adjoining the journal substantially as herein-
before described and represented in the accompanying Drawings..
-
Second, the combination of parts of axle, boxes, substantially as herein
before described and represented in the accompanying Drawings..
Third, the employment of a layer or packing of india-rubber or other.
'
