I, DRUITT HALPIN of No 9 Victoria Chambers Westminster in the county
of Middlesex, Engineer, do hereby declare the nature of my invention for
"APPLIANCES TO AXLE-BOXES OF VEHICLES TO PROTECT THE WEARING PARTS OF
THESE AND OF MACHINERY CONNECTED THEREWITH," to be as follows:-
My invention relates to means of protecting from dirt and grit the wearing
surfaces of axles and horn-plates or axle guards and also, where the engines and
machinery of the vehicle are cased in, to protect them from access of dirt or grit
where the axles pass through the casing.
Hitherto there have been fitted on axles collars or pairs of sliding plates forming.
shields which cover the entrance of the axle into the axle box, but these form no
protection to the surfaces of the horn plates or horn blocks or to those of the axle
box which slide on them.
In consequence of the wear and looseness thus caused, there is great shake when
the driving or braking power is applied.
Now according to my invention,
case in these surfaces by a horn box and
I apply such shields to the vertical facing of this horn box so that not only are the
axle and the interior of the axle box protected, but also the exterior sliding surfaces
of the axle-box and the interior sliding surfaces of the horn-box, on which those of
the axle box work.
When the engines or machinery of the vehicle are cased in, make good the
casing to the horn box and consequently protect all within the casing from access
of dirt or grit. In cases where the axle passes through to carry a wheel outside,
I apply shields such as I have described to both sides of the horn box.
When however the axle and the machinery connected with it are cased in, the
shield is only required outside the horn-box. Sometimes the wheel is inside
the axle box, in which case the shield is applied to the inner side of the horn-box.
When the wheel is inside and a crank outside the axle-box, I case over the crank
and make good this casing to the horn box, and I apply the shield inside the horn
box between it and the wheel. In order to apply my invention to existing
vehicles, I attach to the ordinary axle guards horn boxes such as I have described
with their shields fitted to them.

I, DRUITT HALPIN of N° 9 Victoria Chambers, Westminster in the County
of Middlesex, 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:-
My invention relates to means of protecting from dirt and grit the wearing
surfaces of axles, and horn plates, or axle guards, and also where the engines and
machinery of the vehicle are cased in protecting them from access of dirt or grit
where the axles pass through the casing. Hitherto these have been fitted on axles,
collars or pairs of sliding plates forming shields which cover the entrance of the
axle into the axle box, but these form no protection to the surfaces of the horn
plates, or horn block or to those of the axle box which slide on them. In
consequence of the wear and looseness thus caused there is great shake when the
driving or braking power is applied.
Now, according to my invention, I case in these surfaces by a born box, and
I apply such shields to the vertical facing of this horn box, so that not only are
the axle and interior of the axle box protected, but also the exterior sliding
surfaces of the axle box, and the interior sliding surfaces of the horn box, on which
those of the axle box work.
When the engines or machinery of the vehicle are cased in I make good the
casing to the horn box, and consequently protect all within the casing from access
of dirt, or grit. In cases where the axle passes through to carry a wheel outside,
1 apply shields such as I have described to both sides of the horn box.
When however the axle and the machinery connected with it are cased in, the
shield is required only outside the horn box.
Sometimes the wheel is inside the axle box in which case the shield is applied to
the inner side of the horn box.
When the wheel is inside and a crank outside of the axle box, I case over the
crank and make good this casing to the horn box, and I apply the shield inside
the horn box between it and the wheel. In order to apply my invention to
existing vehicles I attach to the ordinary axle guards, horn boxes such as I have
described with their shields fitted to them.
In the accompanying drawings illustrating my invention as applied in the
various cases referred to above, the same reference numbers are as far as possible
used to iudicate corresponding parts.
Fig. 1 is a vertical longitudinal section of horn block, axle box, and bearing
according to my invention such as may be used for the tender of an ordinary
railway locomotive. Fig. 2 is a vertical transverse section, and Fig. 3 is a sectional
plan.
1 is the axle, 2 the brass bearing of the usual form, 3 the axle box proper, 4 the
horn block which is fastened to the frame 8 in the usual way. The bottom 5 of
the horn block is held by bolts 9, and the front is closed by a vertical plate in one
piece with the bottom. 6 is a dust shield hereafter more fully described, which

page_text: prevents dust from entering the horn box and thus protecting the bearing of the
journal as well as the vertical rubbing surfaces of the axle box and its guides in
the hornblock. 7 is the vertical spring pillar which passes through the top of the
horn box and transmits the thrust of the bearing spring to the axle box. 8 is the
frame of the vehicle to which the hornblock is attached in the usual manner. 11 is
a pad which is held up against the underside of the journal by the spiral spring 12
and is supplied with oil by wicks 17 from the lower part of the hornbox which
forms an oil reservoir that can be replenished from outside through the tube 13.
Figs. 4, 6, and 11 are side elevations and Figs. 5, 7 and 12 are vertical sections
of the dust shields which are made in the well known manner of wood, metal,
leather, papier maché, vulcanite or other suitable material. The shield shewn in
Figs. 4 and 5 consists of two plates having holes in or near their centres for the
axle to pass through, when these holes become worn the two plates are made to
slide along one another by means of the four springs 15 placed in slots in the plates
of the shield and bearing against the ends of these slots in such a manner as to
press the one plate upwards and the other downwards.
Figs. 6 and 7 shew a dust shield consisting of two plates both cut to V shape so
as to fork over the axle and provided with two springs 15. Figs. 11 and 12 shew
a modification of the shield in which a blade spring 15 is used, this spring being
fastened to one plate of the shield, and bearing against the edge of the other plate.
Figs. 8, 9 and 10, shew an arrangement of bearing inside the wheel, having two
dust shields such as are shewn in Figs. 6 and one inside, and the other outside.
Fig. 13 shews my arrangement applied to locomotive or tramway engines having
inside cylinders, and Fig. 14 shew it applied in the case of outside cylinders.
Engines of both these classes are protected from dirt by casings 10 which are
usually provided with suitable dust tight doors for examination and oiling.
Figs. 15 and 16 shew my arrangement applied to the axle boxes such as those of
passenger and goods stock on railways, where the action of powerful brake power
produces a severe thrust on the horn blocks. Here the horn block 4 is bolted
firmly to the ordinary axle guard 8, the spring pillar 7 transmits the thrust of the
spring 18 to the axle box.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be perforined I declare that what
I claim is:-
In combination with the axle box of a vehicle, a fixed horn box within which
the axle box is fitted to slide vertically, the said horn box being closed or shielded,
to prevent access of dirt or grit substantially as herein described and illustrated by
the accompanying drawings.
