PROVISIONAL SPECIFICATION.
Improvements in Metallio Axle-guards for Rolling Stock.
I, JOSEPH STRICKLAND, of 32, Wharfe View, Ben Rhydding, near Leeds, in
the County of York, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to certain improvements in axle guards for rolling stock,
and has for its object, the construction of a guard in such a manner, as to obtain
the greatest strength with the least possible weight of material, at the same time,
avoiding welding or rivetting, thereby ensuring great economy, combined with
safety.
The axle guard as constructed according to my invention, consists of a plate cut
to the required shape, which when heated is pressed by male and female dies in
such a manner, as to form a channel shaped flange passing along all sides and top.
The channel shaped flange at the inside is formed with sufficient material to be
bent over, to form an edge of box shaped section, which not only strengthens the
guard, but forms guides for the axle box to slide up and down when working.
Additional strength when required may be given to the axle guard by forming
channel shaped grooves transversely to the edges, and by dishing other plain parts
of the plate.
In order to reduce the shearing strain to a minimum on the bolts for securing the
axle guard to the sole bar of the carriage or the like, I emboss on the said guard
projections in such a manner that the sole bar rests thereon.
Dated this 17th day of April 1895.

Improvements in Metallic Axle-guards for Rolling Stock.
I, JOSEPH STRICKLAND of 32, Wharfe View, Ben Rhydding, near Leeds, 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 :-
This invention relates to certain improvements in axle guards for rolling stock
and has for its object the construction of a guard in such a manner as to obtain the
greatest strength with the least possible weight of material, at the same time
avoiding welding or rivetting, thereby ensuring great economy, combined with
safety.
In order that my invention may be fully understood, I will describe the same in
detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents a view of my improved axle-guard secured to the sole bar of
the vehicle, and
-b; c-d; e-f; g-h;
Figs. 2. 3. 4. 5 and 6 are sections through the lines a-
and ij. respectively.
The axle guard is indicated by the letter A. and consists of a plate cut to the
required shape which when heated is pressed by male and female dies in such a

top as shewn. This channel shaped flange is specially adapted to increase the
strength for sustaining lateral pressure.
The channel shaped flange at the inside groove A' A' is formed with sufficient
material to be bent over to form an edge of box shaped section as shewn in Fig. 6,
by which I not only strengthen the guard but form guides for the axle box to slide
up and down when working.
Additional strength when required may be given to the axle guard by forming
channel shaped grooves transversely to the edges and by dishing other plain parts
of the plate where this can be done.
In order to reduce the shearing strain to a minimum on the bolts G. for securing
the axle guard A. to the sole bar F, I emboss on said guard A. projections D. D.
somewhat in the position shewn and in such a manner that the sole bar rests
thereon, thereby relieving to a great extent the shearing strain which would
otherwise fall upon bolts G. G, and as a further protection for the bolts I may if
desired form a flange H. around the bolt holes as shewn.
Fig. 7 is a sectional view somewhat similar to Fig. 4 but illustrates a modification
of my improved axle guard shewing same made out of two plates, thereby causing
a great saving in material without affecting the efficiency of the guard.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is,
1. An axle guard made by stamping or pressing a plate of metal so as to form
thereon a channel shaped flange around the edge thereof, and the formation of
flanges around the bolt holes, substantially as described.
2. An axle-guard made by stamping or pressing a plate of metal so as to form
thereon a channel shaped flange around the edges thereof, the inner edges being
further formed into a box shaped section so as to serve as guides for the axle box,
substantially as described.
3. In axle guards formed of plate, the combination therewith of embossed
projections such as are shown at D. for the purpose of supporting the sole bar,
substantially as described.
4. An improved axle guard, substantially as herein before described.
