Improvements in or conneoted with Railway Axle-boxes.
We, RICHARD KERR, of 19, Bradshaw Street, Whelley, Wigan, and JOHN
NESBITT PATTERSON, of Lismore House, Earlestown, both in the County of
Lancaster, Moulder and Doctor of Medicine respectively, do hereby declare the
nature of this invention to be as follows:-
This invention relates to railway axle-boxes, and its object is to provide a more
convenient means of hinge-connection between the axle-box and its lid.
In axle-boxes as at present constructed, the lid is hinged by a pin passed right
through the sougs or interlocking projections formed on the lid and on the box,
which necessitates drilling of the snugs and interlocking projections to make a
passage for the pin, which latter is then riveted in position.
Now the present invention consists in forming on the snugs or interlocking
projections of the lid, pius or projections to act as pivots for the hinge, and in
forming in the corresponding snugs or interlocking projections of the axle box,
recesses to receive the said pivots. These recesses are formed as slots or short
grooves running from the rear of the snugs or interlocking projections to the centre
thereof where they are somewhat enlarged so as to preferably form a key-hole
socket, and the pivots on the lid are flattened a little to just permit of their entering
the recess at the rear.
To connect the lid to the box, it is held with the under side upwards at the rear
of the box and pulled forward until its pivots enter, from the rear, the corresponding
grooves in the box saugs, and is then shut down, the pivots turning freely in the
sockets.
The shape of the sockets, and the flattening of the pivots entirely prevent the
lid coming off or being removed, except by turning it completely back and then
sliding it out of the sockets, and this can only be done by lifting the wagon or
removing the spring.
Whilst we have described one form of construction it will be readily understood
that the same may be modified without departing from the spirit of the invention.
For instance the pivots may be formed on the box, and the sockets on the lid snugs,
aud they may project towards each other from the inner faces of two snugs, or
project outwardly from the ends of a single snug or interlocking projection, the
corresponding sockets being formed accordingly in either the snugs or the
interlocking projections. The number of interlocking projections or snugs may be
varied as desired.
By this invention all drilling is done away with, an the pivots and sockets can be
formed in the casting of the box and lids, and the cost of manufacture is thus
considerably reduced. Moreover the lids may be easily removed or replaced at
any time.

We, RICHARD KERR of 19 Bradshaw Street, Whelley, Wigan and JouN
NESBITT PATTERSON of Lismore House, Earlestown, both in the County of
Lancaster, Moulder and Doctor of Medicine respectively, du hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to railway axle-boxes, anil its object is to provide a more
convenient means of hinge-connection between the axle-box and its lid.
In axle-boxes as at present constructed, the lid is hinged by a pin passed right
through the suga or interlocking projections formed on the lid and on the box,
which necessitates drilling of the snugs and interlocking projections to make a
passage for the pin, which latter is then rivetted in position.
Now the present invention consists in forming on the snugs or interlocking
projections of the lid, pins or projections to act as pivots for the hinge, and in
forining in the corresponding snuga or interlocking projections of the axle-box,
recesses to receive the said pivots. These recesses are formed as slots or short
grooves running from the rear of the snugs or interlocking projections to the contro
thereof where they are somewhat enlarged so as to preferably forin n key-holo
socket, and the pivots on the lid are flattened a little to just permit of their entering
the recess at the rear.
In the accompanying drawings,
Figures 1 and 2 show in isometrical projection two axle boxes fitted with this
improved hinge connection, Figure 1 showing two snugs on the box with ono
interlocking piece or snug on the lid, whilst Figure 2 shows two snugs on the lid
with a single interlocking piece or snug on the box.
In these, A is the box, B, the lid, b chamfered edge of the latter, C the pivots,
the suugs, D the keyholo recesses or sockets, d the interlocking piece or
Euug.
To connect the lid B to the box, it is held with the under side upwards at the
rear of the box as shown in Figure 1, and pulled forward until its pivots Center,
from the rear, the corresponding grooves or keyhole recesses D in the box snugs c,
und is then shut down, the pivots turning freely in the sockets.
The keyhole shape of the sockets D, and the flattening of the pivots C entirely
prevent the lid coming off or being removed, except by turning it completely back
and then sliding it out of the sockets, and this can only be done by lifting the wagon
or removing the spring. The lid when shut down cannot be pushed back as its
chamfered edge & bears against the snugs c in the case of Figure 1, and against the
interlocking piece d in the case of Figure 2.
It will be readily understood that the positions of the parts may be modified
without departing from the spirit of the invention. For instance, the pivots may
be formed on the box, and the sockets on the lid snugs; or said pivots may, as
shown in Figure 2, project towards each other from the inner faces of two anugs c,
or project outwardly from the ends of a single snug or interlocking projection d, as
shown in Figure 1, the corresponding sockets being formed accordingly in either
the snugs c or the interlocking projection d. The number of interlocking projections
or snugs may be varied as desired.
By this invention all drilling is done away with, as the pivots and sockets can be
formed in the casting of the box and lids and the cost of manufacturo is thus
considerably reduced. Moreover the lids may be easily removed or replaced at
any time.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvement in or connected with axle-boxes which consists in forming
the hinged connection of the lid with the box by means of flattened projections or
pivots on the lid engaging in keyhole recesses or sockets on the box, or vice versa,
in such a manner that the lid when thrown back may be removed from the box by
moving it backwards so as to disengage the pivots and recesses, but is securely
hinged to the box in all other positions, substantially as hereinbefore set forth.
2. Forming the hinge snugs or interlocking pieces of axle boxes, or of axle-box
lids, with recesses, grooves or sockets of key-hole form, and providing flattened
projections or pivots on the corresponding snugs or interlocking pieces of the box,
or the lid as the case may be, to engage in said recesses and form a hinge connection
between the box and lid, substantially as and for the purposes herein before set
forth.
3. The improved hinge connection for axle box lids substantially as described and
