Locomotives for Preventing Accidents.
K
I THOMAS BOLTON WATERFIELD of 90 Haddington Road in the County of Dublin
Ireland Civil Engineer do hereby declare the nature of this invention to be as
follows:-
Guards as at present used in connection with tramcars locomotives and such like
vehicles consist of a V shaped or hemispherically constructed apparatus which is
rigidly attached to the frame work of the vehicle.
By this method of attachment it is obvious that as the vehicle oscillates or pitches
longitudinally the guard is necessarily carried with it and is consequently somewhat a
source of trouble, owing of its tendency to strike or "bump" the ground; and also
for the same reason it cannot be carried sufficiently near the roadway to effect
satisfactorily the object for which it is designed.
Now the object of my Invention is to obviate this defect, and to this end, I propose
to prolong the ends, or sides, of the guard and attach same securely with a broad base
by means of bolts, or rivets to the axle boxes of the vehicle, so as to carry the guard
entirely free of the body or frame work of the vehicle.
By applying the guard in this manner it is obvious that it will act independently,
or in other words maintain a constant horizontal position irrespective of the rise or
fall of the body of the vehicle caused by its being empty or loaded; and it is also
evident that my improved guard cannot be affected by the longitudinal oscillation or.
pitching of the vehicle when running over rough or uneven roadways. This arrangement
also enables the guard to be constructed of deeper section, that is to be carried in closer
proximity to the rails or roadway as the case may be.

I THOMAS BOLTON WATERFIELD, of 90 Haddington Road, in the County of
Dublin Ireland Civil 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 :-
Guards as at present used in connection with tram-cars, locomotives, and such like
vehicles usually consist of a V shaped, or hemispherically shaped, apparatus which
is generally attached to, or carried rigidly by the frame work of the vehicle.

By this method of attachment it is obvious that as the vehicle oscillates, or pitches
longitudinally the guard is necessarily carried with it, and is consequently somewhat
a source of trouble, and inconvenience, owing of its tendency to strike or bump'
the ground, and also for the same reason it cannot be carried sufficiently near the
roadway to effect satisfactorily the object for which it is designed.
Now the object of my Invention is to obviate these objections, and to this end I
propose to prolong the ends, or sides of the guard, and attach same securely with a
broad base by means of bolts, or rivets to the axle boxes of the vehicle so as to carry
the guard entirely free of the body, or framework of the vehicle.
By applying the guard in this manner, it is obvious that it will act independently,
or in other words maintain a constant horizontal position irrespective of the rise, or
fall, of the vehicle caused by its being empty or loaded, and it is also evident my
improved guard cannot be affected by the longitudinal oscillation, or pitching of the
vehicle when running over rough, or uneven roadways.
This arrangement also enables the guard to be constructed of deeper section,
that is, to be carried in closer proximity to the rails or roadway as the case may be.
In order that my said Invention may be more readily understood and carried into
practice I will describe the accompanying Drawings: Fig. 1 represents a partial side
elevation of a tramcar showing the application of my improved guard; and Fig. 2
is a plan of the guard attached to the ordinary axle boxes of a tram car, or other
vehicle.
A, A, are suitably shaped plates of metal which are bolted firmly direct, to the
ordinary axle boxes a, a, and to which are secured the ends of the guard b, b. The.
pointed ends of the guard may be connected, and protected by a shoe, or strap of iron c,
or other convenient method.
When it is desired to secure the guards inside the wheels as in the case of locomo-
tives the method indicated by the dotted lines d. d, may be adopted; e, e being the
axle boxes in this instance; ff (Fig. 2) show the ordinary tram rails.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I desire to say that since
filing my Provisional Specification I find attempts have been made to carry
guards in front of the wheels independently of support from the body or frame-work
of the vehicle, and to such method, or methods I lay no general claim; but what I
consider original and useful is,
The method of securing guards to tramcars, locomotives and other similar vehicles,
whereby said guards are carried wholly independent of the framework or body of the
vehicle in the manner substantially as herein described and set forth.
