A SAFETY TRUSS AND AXLE PROTECTOR FOR ALL KINDS OF RAILWAY ROLLING STOCK
Year: 1884

page_text: I, HENRY PARKS Wincham House Northwich Cheshire Salt Proprietor do
hereby declare the nature of my Invention for A SAFETY TRUSS AND AXLE
PROTECTOR FOR ALL KINDS OF RAILWAY ROLLING STOCK to be as follows:-
To have cast iron truss in centre of axle, keyed on with wood and iron wedges,
or iron or steel keys and cast iron (or any other metal) tubes, to protect the axle,
to be grooved in the bosses of wheels and in the truss in centre of axle, the ends
of tubes to be cast bell mouthed, so as to have strength of metal round the holes
in bosses and truss, the grooves to be run full of lead and corked, to make the
axle secure from salt, air and all chemical action whatever. The truss to leave
holes to receive bolts, the bolts to pass through bosses of wheels and truss, the
bolts to be made thicker in centre where they pass through the truss and screwed
with nuts on both sides of truss, also each end, to keep the wheels in a proper
position, so that if the axle breaks the wheels will still run. If adopted to old
wheels, to have circular plates to fit on face of spokes, and truss bolts to pass
through spokes and plate, to be screwed with nuts outside. The truss and tubes
to be applied separately if necessary, the truss to be in wrought or cast iron.

page_text: I, HENRY PARKS Wincham House Northwich Cheshire Salt Proprietor do
hereby declare the nature of my Invention for A SAFETY TRUSS AND AXLE
PROTECTOR FOR ALL KINDS OF RAILWAY ROLLING STOCK and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of my Invention is to protect and strengthen the axles of the wheels
of railway carriages, wagons or any other kind of railway rolling stock so as to
prevent corrosion or breakage of the same, which is especially liable to occur when
the wagons are employed to carry salt and other chemical substances; and in order
that the said Invention may be clearly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof and have marked the same with Figures
and letters of reference corresponding with those in the following explanation
thereof.
Fig. 1. in the Drawing is a view of the truss which I key to the centre of the
axle as hereinafter described.
Fig. 2 shows the construction of the wheels themselves.
Fig. 3. is a side view of the axle with my improved safety truss and axle
protector applied thereto.
Figs. 4 and 5 illustrate modifications of my Invention.
At the centre of the axle as shown at Fig. 3 I key or otherwise fix a truss A,
of cast iron or other suitable metal provided with circular grooves a¹, a¹ (Fig. 1)
on either side into which fit the ends of tubes B the other ends of which fit into
similar grooves a², a² formed in the bosses of the wheels. I also apply strengthening
bolts C passing through the snugs D formed upon the truss A, the ends of the
said bolts also passes through snugs E formed on the boss of each wheel and being
securely fastened by nuts on either side of the snugs D, and on the outer side of
the snugs E.
I would here remark that in applying these truss bolts C to old wheels upon
which the snugs E could not of course be formed I employ a circular plate on
the outside of the spokes of each wheel and the bolts C are passed through these
plates and through (or between) the spokes of the wheels, being secured by nuts
outside the plates. This however being self evident I have not illustrated."
I prefer to make the tubes B bell mouthed at their ends, so as to leave sufficient
strength of metal round the holes in the truss and in the bosses of the wheels;
and the grooves in the said truss and bosses are run full of lead and "caulked" or
otherwise secured to make a good joint.
I also fill the spaces between the axle and
or other non corrosive substance by which
from the deleterious action of salt or air or
the same and cause it to break.
the tubes with red lead and oakum
means I effectually protect the axle
other chemical which might corrode
The truss A. and bolts C at the same time taking the strain off the axle.
It is evident that although the truss and bolts and the tubes have been described
as applied to the axle conjointly it might be necessary or preferable in some cases
to apply only the truss A, and bolt C as shown at Fig. 4 or in other cases to employ
a protecting tube B alone as shown at Fig. 5.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what

page_text: I claim is the truss A. and bolts C, and the tubes B whether applied conjointly
or separately to the axles of all kinds of railway rolling stock substantially as
hereinbefore described and illustrated by the annexed Drawings.
