Improvement in Apparatus for Lubricating the Journals and
Bearings of Railway Vehicles and other analogous Vehicles
Using Oil Axle Boxes.
ROBERT HYDE, Derbyshire House, Darnall, Sheffield, in the County of York,
Engineer do hereby declare the nature of this invention to be as follows:-
Various methods are now in use for lubricating railway carriage axle bearings,
most of them use one, two, or more springs to press the oil pad to the journal.
The springs so used are strongest when the steps and journal are new and in many
cases press the oil pad hard against the journal, which prevents the oil from
flowing to the journal, consequently the lubrication is done very imperfectly.
The result is, the bearings are heated by extra friction and burns the oil pad
sometimes causing stoppage and serious delay to trains.
My improved apparatus is arranged so as to give nearly an uniform pressure
with the oil pad against the journal, its pressure will be nearly the same when the
bearing and journal are new as when old and worn very much.
In my apparatus I use one or more springs, which acts on two or more levers,
by preference I use two springs any suitable shape and four levers. The levers
are provided with holes in each and are connected by two spindles working in
slots made for them in the same plane in a bent plate forming part of lubricator
frame. The frame for oil pad is made any suitable shape and secured to top of
bent plate. The ends of each pair of levers are guided by a slot, and a pin passing
through them. The slots are at right angle to the slots for the spindles. On one
of the spindles a lever is secured at each end, the levers on the other spindle ends
can be secured or not.
The spring or springs are fixed in connection with the spindles to pull them
towards each other thereby making the pins in ends of levers to travel towards
the top of the slots. The spindles being connected to the levers a short
distance from the pins cause the levers to approach in each pair and form a small
four legged trestle in appearance. When pressure is put on the top of the
apparatus the levers slide outward and thus causing the top frame to come down.
If the pressure is released the springs acting on the spindles and levers raise the
frame again. The pressure required to press the frame down is nearly the same
during the whole of its travel down, it therefore,exerts nearly an uniform pressure
on the oil pad which is secured on top of frame, the oil pad is pressed lightly
against the journal. The pressure is only sufficient to keep oil pad against
journal, it will allow the oil to flow freely on the journal, thereby reducing friction
and keep the bearings in good condition.
In action the apparatus is made to press lightly against the journal, the springs
acting on the spindles and levers in such a manner that the leverage is longest
when the springs are strongest and when the springs are weak the leverage is short
thereby giving nearly an uniform power.
The apparatus can be used in connection with axle boxes now in use.
The apparatus can be made of any suitable material or combination of
materials.

ROBERT HYDE Derbyshire House Darnall Sheffield in the County of York
Engineer do 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 :-
Various methods are now in use for lubricating railway carriage axle bearings
most of them use one, two, or more springs to press the oil pad to the journal.
The springs so used are strongest when the steps and journals are new and in
many cases press the oil pad hard against the journal which prevents the oil from
flowing to the journal, consequently the lubrication is done very imperfectly.
The result is, the bearings are heated by extra friction and burns the oil pad,
sometimes causing stoppage and serious delay of trains.
My improved apparatus is arranged so as to give nearly an uniform pressure
with the oil pad against the journal: its pressure will be nearly the same when the
bearing and journal are new as when old and worn very much.
In my apparatus I use one or more springs, which act on two or more levers, by
preference I use two springs any suitable shape, and four levers. The levers are
each provided with holes and are connected by two spindles working in slots made
for them in a bent plate forming part of lubricator frame.
The frame for oil pad is made any suitable shape and secured to top of bent
plate. The ends of each pair of levers are guided by a slot and a pin passing
through them. The slots are at right angle to the slots for the spindle ends. On
one of the spindles a lever is secured at each end, the levers on the other spindle
ends can be secured or not.
The spring or springs are fixed in connection with the spindles to pull
them towards each other thereby making the pins in ends of levers to travel
toward the top of the slots, the spindles being connected to the levers a short
distance from the pins, cause the levers to approach in each pair and form a small
four legged trestle in appearance. When pressure is put on the top of the
apparatus the levers slide outward and thus causing the top frame to come down,
if the pressure is released the springs acting on the spindles and levers raise the
frame again. The pressure required to press the frame down is nearly the same
during the whole of its travel down, it therefore exerts nearly an uniform pressure
on the oil pad which is secured on top of frame, the oil pad is pressed lightly
against the journal. The pressure is only sufficient to keep oil pad against journal,
it will allow the oil to flow freely on the journal thereby reducing friction and
keep the bearings in good condition.
In action the apparatus is made to press lightly against the journal, the springs
acting on the spindles and levers in such a manner that the leverage is shortest
when the springs are strongest and when the springs are weak the leverage is
longest thereby giving nearly an uniform power.
The apparatus can be used in connection with axle boxes now in use.
In order that my said invention may be more fully understood, the mode which
I prefer to carry it into effect is illustrated on the accompanying sheet of
explanatory drawings which are marked with figures and letters of reference
corresponding with those in the following description thereof.

Fig. 1 cross section shows the bearing a in position on the journal of a railway
carriage axle. The lubricator pad c is secured on any suitable frame d having
perforations m or spaces in for the wicks n to pass through for conveying-
oil to pad c.
The bent plate e and frame d are secured together. The bent
plate e has slots f & 1 Fig. 3 at each end of plate in the same plane in
which the spindles g & g1 Fig. 2 work. On the ends of the spindle two
twisted levers or supports are secured h & 1 Fig. 2. These work close to.
the bent plate
e as shown Fig. 2. The spindle gl has two twisted levers or
supports 2 & 3 Fig. 2. These work outside levers h & 1 and the ends of h
& 2 and 1 & 3 are connected by small pins i & 1. Each pin passes through
two lever ends with round holes and bent plate e which has slots k at right angles.
to f& fl. The spindles g & g 1 have one or more springs connected to them by
preference two & 11. These have loops at each end through which the spindles.
are passed as shown Fig. 2. The springs 1 & 11 cause the spindles g & g 1 to press
in the ends of the slots f & f1 as shown in Fig. 3. The levers or supports being
connected to the ends of the spindles g & g 1 they are held in the position shown
Fig. 3 by the contracted condition of the springs 1 & 11. When the frame d is.
pressed down the springs elongate and the levers or supports take a corresponding
position 4 & 5 Fig. 3 relatively to the frame d, or the levers or supports will
take any intermediate position between 1 & 5 or h3 & 4 Fig. 3 as required..
The frame d keeps nearly parallel with the ends of the levers or supports / h 1.
h2. & 3 which causes the pad e to bear evenly on the journal 6 by the tension or
pressure of the spring or springs 1 & 11 Fig. 2, acting on the spindles g & g 1, these
being connected to levers h. h 1 h2 & h3 cause the apparatus to stand in the
position shown Fig. 3.
The frame d can be pressed down by a little pressure but will be lifted up as
soon as the pressure is released by the tension of the spring or springs.
In pressing the frame down the small pins i & il move down the slots k
Fig. 3 at the same time reducing the leverage between the spindle g and pins i
& 1, also between 91 and pins ; & il by shortening the leverage at the same time
as the tension of the springs & 1 is being increased, by this joint action nearly
an uniform pressure is given in any part of its travel up or down. The springs
can be varied to suit special requirements. The levers h. h 1. h 2. & h 3 being
connected to the spindles g & g1 and the spindles working in slots f& fl at
each end of bent plate e, the levers or supports are connected in pairs by the pins i
& i1 working in the slots k. Should one or more of the levers or supports be
pressed the other levers or supports assume nearly a corresponding position. This
feature makes it easily put into axle boxes where there is little space and also
facilitate its withdrawel which is very important.
The apparatus will suit nearly all kinds of axle boxes using oil.
The apparatus can be made of any suitable material.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The novel and special construction of apparatus, for lubricating the journals
and bearings, of railway carriages, and other analogous vehicles, using liquid
lubricants, substantially as herein before described, or set forth.
2nd. The improved mechanism and arrangement of spring or springs, and levers
giving nearly an uniform pressure against the journal in any part of its travel as
shown in the accompanying drawings and substantially as herein before described,
