IMPROVEMENTS IN AXLE-TREE BOXES
Year: 1853

page_text: LETTERS PATENT to Leopold Joseph Green, of Leatherhead, in
the County of Surrey, Ironmonger and Whitesmith, for the
Invention of "IMPROVEMENTS IN AXLE-TREE BOXES."
PROVISIONAL SPECIFICATION left by the said Leopold Joseph
Green at the Office of the Commissioners of Patents, with his
Petition, on the 7th April 1858.
I, LEOPOLD JOSEPH GREEN, of Leatherhead, in the County of Surrey,
Ironmonger and Whitesmith, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN AXLE-TREE BOXES" to be as follows:-
This Invention consists of using a ring or hollow screw, which screws
into the inner end of an axle-tree box, and by a fixed collar or projection
on the axle-tree the screw ring retains the axle-trec in its box. The
screw ring is fixed or locked by means of a bolt or catch on a bent spring,
which partly embraces the axle-tree box. The bolt passes through a
hole in the box, and enters a recess in the screw ring. The outer end
of the box is covered by a screw cap, which is hollow, and part of the
hollow is covered by a plate, by which oil can be placed in the cap
before it is applied to the box; and the box is cast with a hollow

filed by the said Leopold Joseph Green, in the Great Seal Patent
Office, on the 7th October 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
LEOPOLD JOSEPH GREEN," of Leatherhead, in the County of Surrey,
Ironmonger and Whitesmith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Leopold Joseph Green, Her special licence
that I, the said Leopold Joseph Green, my executors, administrators,
and assigns, or such others as I, the said Leopold Joseph Green, 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-TREE BOXES," upon the condition (amongst
others) that I, the said Leopold Joseph Green, 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 Leopold Joseph Green, 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 consists of using a ring or hollow screw, which screws
into the inner end of an axle-tree box; and by a fixed collar or pro-

page_text: jection on the axle-tree the screw ring retains the axle-tree in its box.
The screw ring is fixed or locked by means of a bolt or catch on a
bent spring, which partly embraces the axle-tree box. The bolt pass-
ing through a hole in the box, and enters a recess in the screw ring.
The outer end of the box is covered by a screw cap, which is hollow,
and part of the hollow is covered by a plate by which oil can be placed
in the cap before it is applied to the box, and the box is cast with a
hollow longitudinal projection, with an opening into the interior of the
box by which oil may be supplied.
Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, shows the section of an axle-tree box, having my improve-
ments applied thereto. Figure 2, is the cap, and Figure 3, is a screw
ring, which embraces the axle-tree, and screws into the axle-tree box.
Figure 4, shows another axle-tree box, having a similar screw cap,
Figure 2, and a screw ring which is shewn at Figure 5; but in this
arrangement the screw ring embraces the axle-tree and screws outside
of the box. In each of these Figures, as well as the other Figures
shown in the drawing, the same letters are used to indicate similar
parts. a, is the axle-tree box into which the axle-tree fits, the axle-tree
being made with a collar, which fits the recess a¹; and the box a, is
cast with an outer longitudinal hollow projection a², there being pas-
sages a³, communicating with the interior of the axle-tree box, and the
outer end of this hollow projection is closed by means of the screw a'.
The outer end of the axle-tree box is closed by a screw cap b, which is
hollow, and is nearly closed in by the plate 6'; hence before screwing on
the cap, it may be supplied with oil at the back end. The box receives a
screw ring c, which either screws on or into the end of the box, and
by reason of the axle-tree having a collar or enlargement retains the
axle-tree within the box. The screw ring c, is made with recesses to
receive a bolt or catch mounted on a spring. In the arrangement
Figures 1, 2, and 3, the spring d, is fixed to the exterior of the box;
and in the arrangement shown at Figures 4, and 5, the spring d, is

page_text: fixed to the screw ring. The manner, however, of the action of this
spring and its bolt, whether fixed to the box a, or to the screw ring c,
is the same, for when in use it retains the bolt or catch e, in one of the
recesses; thereby prevents the screw ring moving either forward or
backward; and this the spring does without any elastic force; and it is
only made as a spring to facilitate the removal of the bolt or catch.
When it is desired to remove the axle-tre box off the axle-tree, or when
it is desired to screw the ring more or less tight, then by bending
the spring the bolt or catch may be moved out of the recess, and thus
admit of the screw ring being turned either to remove it, or to screw it
more or less tight; and on releasing the spring the bolt or catch will
assume its place, and the spring will be in its quiescent condition, and
will retain the bolt or catch in its place.
I would remark that the form and position of the bolt and spring
may be varied, and such is the case in regard to other details.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I
do not claim any of the parts separately; but what I claim is the com-
bination of parts herein described.
In witness whereof, I, the said Leopold Joseph Green, have
hereunto set my hand and seal, this Fifth day of October,
in the year of our Lord One thousand eight hundred and fifty-
three.
Witness, JNo. Cook,
LEOPOLD JOSEPH GREEN. (L.S.)
