PROVISIONAL SPECIFICATION left by the said John Wheeler Elliot
at the Office of the Commissioners of Patents, with his Petition, on
the 13th May 1870.
I, JOHN WHEeler Elliot, of the City of Toronto, in the County
of York, in the Province of Ontario, and Dominion of Canada, Surgeon
Dentist, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN APPARATUS FOR REMOVING SNOW FROM LINES OF RAILWAY," to be
as follows:-
My Invention has for its object the construction of snow ploughs,
(or apparatus for removing snow from railways) adapted to remove
snow when in a wet or heavy condition, and consists in the combina-
tion of a box or receiver with a revolving wheel with flat arms working

page_text: at right angles to the line of rails. The box and wheel are supported
on a truck, on which is mounted a small boiler and engine for driving
the wheel. The truck with the said apparatus is coupled in front of a
locomotive, or the apparatus may be used for removing snow from a
railway without being connected with a locomotive. The sides of the
box are made by preference of the width of the arms of the revolving
wheel and parallel with each other, and with the sides of the box spread
at one part so as to gather the snow upon the sides of the railway into
the revolving wheel and keep the wheel as small as possible, but the
wheel may be made of the full width of the part desired to be cleared,
the sides of the box being carried parallel all the way. The back of
the box is made convex pointing to the front in order to increase its
strength for resisting the pressure of the snow. In the upper part of
the box is formed an aperture through which the snow may be driven
out by the revolving arms of the wheel. This outlet for the snow
may be regulated by forming the box with a double case or otherwise.
The wheel with its driving parts is arranged so as to admit of its being
driven in either direction, in order to throw the snow on either side of
the line as may be required.

that I, the said John Wheeler Elliot, my executors, administrators, and
assigns, or such others as I, the said John Wheeler Elliot, my execu-
tors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term

page_text: therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR REMOVING SNOW FROM LINES OF RAILWAY," upon the condition
(amongst others) that I, the said John Wheeler Elliot, my executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said John Wheeler Elliot, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is to
say) :—
My Invention of "Improvements in Apparatus for Removing Snow
from Lines of Railway," has for its object the construction of snow
ploughs or apparatus for removing snow from railways, adapted to
remove snow when in a wet and heavy condition, and consists in
the combination of a box or receiver with a revolving wheel with flat
arms working at right angles to the line of rails. The box and wheel
are supported on a truck on which is mounted a small boiler and engine
for driving the wheel. The truck with the said apparatus is coupled
in front of a locomotive, or the apparatus may be used for removing
snow from a railway without being connected with a locomotive. The
sides of the box are made by preference of the width of the armis of
the revolving wheel and parallel with each other, and with the sides of
the box spread at one part so as to gather the snow upon the sides of
the railway into the revolving wheel, and keep the wheel as small as
possible, but the wheel may be made of the full width of the part
desired to be cleared, the sides of the box being carried parallel all the
way. The back of the box is made convex pointing to tlie front in
order to increase its strength for resisting the pressure of the snow,
In the upper part of the box is formed an aperture through which the
snow may be driven out by the revolving arms of the wheel. This
outlet for the snow may be regulated by forming the box with a double

page_text: case or otherwise.
י
The wheel with its driving parts is arranged so as
to admit of its being driven in either direction, in order to throw the
snow on either side of the line as may be required.
Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed
by the aid of the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side and partly sectional view of a snow plough or shovel
connected to a truck; Fig. 2 is a front view of the same; and Fig. 3
is a horizontal section in the line X, Y, of Fig. 2. In these several
Figures the same letters of reference indicate corresponding parts.
The parts which form the snow plough or shovel consist essentially
of a shovel or box A, inside of which is made to revolve a wheel B
with flat arms which forms the compound revolving snow shovel. The
shovel or box A is connected by suitable means to a truck, as shewn in
Fig. 1 on which truck is also mounted a small boiler for the purpose
of supplying with steam the engine which drives the wheel B. The
shovel or box A is by preference constructed of strong boiler plate
well braced with Tiron in the form shewn, or in any other form adapted
for the purpose. In the Figures the sides of the shovel or box A arc
shewn of the width of the arms of the wheel B and parallel, but at the
point D the sides are made to spread, as shewn in Fig. 3, so as to gather
the snow at the sides of the line into the revolving wheel B. This
shape of the box A is adopted in order to keep the wheel B as small
as possible, but if preferred the said wheel may be made of the full
width of the part to be cleared, the sides being parallel throughout.
The back of the shovel or box A is made convex, pointing to the front
to give it strength and thereby enable it to resist the pressure of the
snow against which it is caused to act; and a portion of the box A
is removed in order to form an outlet for the snow. The snow plough
or shovel is fixed in front of a locomotive like the ordinary snow plough.
The boiler C supplies with steam the rotary engine F which is con-
nected with and drives the wheel B, and the engine F being reversible
the wheel B may be caused to revolve in either direction as may be
required. When it is required to clear a line from snow the apparatus
is connected to a locomotive by which it is worked into the drift, the
wheel B is caused to revolve, and as the locomotive advances the box

page_text: or shovel A gathers the snow, and the wheel B revolving as described
dashes out the snow through the aperture E, as shewn by the arrows
in Fig. 2. As the wheel B is made to revolve with great rapidity the
snow is cleared from the box or shovel A before it has time to become
hard and immoveable. There is an advantage in being able to make
the wheel B revolve in either direction, as the snow may thereby be made
to fall on whichever side of the line is found most convenient, for
instance, should there be an embankment on one side, the snow may be
discharged on the other, or when there is a side wind the snow may be
discharged so as to take advantage of it. The portion of the box A
which surrounds the wheel B may if preferred be made in the form of a
double case in order to shift the aperture E if necessary, in which case
about one-half of the inner case would be cut away and the aperture
regulated to its size by the outer one.
Having thus described the nature of the said Inventiou and in what
manner the same is to be performed, I hereby declare that what I claim
as of my Invention is, the machine or apparatus described and con-
sisting in the combination of a box or case, adapted in form to act as a
shovel (when moved forwards by a locomotive or other motive power),
with a wheel caused to revolve (by the same power) at right angles to
the line of railway, and thereby discharge the snow from the box on to
cither side of the line through a suitable outlet in the box either as
represented or by forming a double case.
I also claim the formation of the box or case in the manner shown
at D, Fig. 3, and described.
In witness whereof, I, the said John Wheeler Elliot, have here-
unto set my hand and scal, the Third day of October, in the
year of our Lord One thousand eight hundred and seventy.
