PROVISIONAL SPECIFICATION.
An Improved Machine for Removing Snow on Railways and
Tramways.
I, CARL WILHELM PAULITSCHKY, of II Gusshaus Strasse No. 101 Vienna, Austria,
Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved machine with chain buckets mounted on a
suitable vehicle for removing snow on railways worked by steam or electricity and on
tramways. I will proceed to describe the same with reference to the accompanying
drawings, in which Fig. 1 shews a longitudinal section, Fig. 2 a plan, and Fig. 3 a
front view with the chain buckets partly removed.
The working part thereof consists of several endless chain buckets arranged side by
side in front of the machine, the buckets being connected to endless chains bands
or equivalent parts passing over drums in the usual manner, whose shafts a a¹ are
carried by the framing of the machine, and receive rotary motion from a suitable
motor engine.
The buckets d have either no bottom, or if they have such, these are free to turn
on hinges at the inner side.
The outer side of the bucket is slotted at the middle, as shewn at Figs. 4 and 5
which shew a front and side view of a detached bucket to a larger scale.
Above the upper shaft a of the chain buckets is a second shaft mounted in bearings
in the framing, on which the snow clearers care situated, there being one for each
set of chain buckets. Figs. 6 and 7 shew such a snow clearer in front and side view,
to an enlarged scale.
The action of the machine is as follows:
The snow scooped up by the ascending buckets is carried up in them, remaining
therein even if they have no bottom, as it readily cakes together; and when the
buckets have arrived in the position d' Fig. 1, the snow clearer c in passing through
the bucket clears the snow out of the same on to an endless travelling web e situated
behind the buckets, the broad blade of the clearer being made to pass through the
open bottoin of the bucket, while the stem thereof passes through the slot in the outer
side thereof.
If the bucket has a hinged bottom as above stated, this is first forced open by the
passage of the blade.
It will be seen that with the abovedescribed arrangement of the clearer, the buckets
are effectually cleared of snow every time, while with the snow dredging machines
heretofore constructed no suitable arrangement has been provided for clearing the
buckets of the snow, and as they consequently gradually become choked with caked
snow, they soon become inoperative.
The shaft b of the snow clearer is driven from the shaft a by suitable speed
increasing gearing (as shown on the drawing, in the proportion of 1 to 6). The
endless travelling web e is also driven from a by means of bevil gear.
The web e is arranged so as to deliver the snow to the side where it does not
interfere with the traffic.

An Improved Machine for Removing Snow on Railways and
Tramways.
1, CARL WILHELM PAULITSCHKY, of II Gusshaus Strasse No. 101, Vienna Austria,
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 an improved machine with chain buckets mounted on a
suitable vehicle for removing snow on railways worked by steam or electricity and on
tramways. I will proceed to describe the same with reference to the drawings
accompanying my Provisional Specification in which Fig. 1 shews a longitudinal
section, Fig. 2 a plan, and Fig. 3 a front view with the chain buckets partly
removed.
The working part thereof consists of several endless chain buckets arranged side
by side in front of the machine, the buckets & being connected to endless chains bands
or equivalent parts passing over drums in the usual manner whose shafts a a¹ are
carried by the framing of the machine, and receive rotary motion from a suitable
motor engine.
The buckets d have either no bottom, or if they have such, these are free to turn
on hinges at the inner side.
The outer side of the bucket is slotted at the middle, as shewn at Figs. 4 and 5,
which shew a front and side view of a detached bucket to a larger scale.
Above the upper shaft a of the chain buckets is a second shaft
mounted in
bearings in the framing on which the the snow clearers c are situated, there being one
for each set of chain buckets. Figs. 6 and 7 shew such a snow clearer in front and
side view, to an enlarged scale.
The notion of the machine is as follows:-
The snow scooped up by the ascending buckets is carried up in them, remaining
therein even if they have no bottom, as it readily cakes together, and when the buckets
have arrived in the position Fig. 1, the snow clearer e in passing through the
bucket clears the snow out of the same on to an endless travelling web e situated behind
the buckets, the broad blade of the clearer being made to pass through the open
bottom of the bucket, while the stem thereof passes through the slot in the outer side
thereof.
If the bucket has a hinged bottom as above stated, this is first forced open by
the passage of the blade.
It will be seen that with the above described arrangement of the clearer, the
buckets are effectually cleared of snow every time, while with the snow dredging
machines heretofore constructed no suitable arrangement has been provided for
clearing the buckets of the snow, and as they consequently gradually become choked
with caked snow, they soon become inoperative.
The shaft of the snow clearer is driven from the shaft a by suitable speed increasing
gearing (as shewn on the drawing, in the proportion of 1 to 6). The endless
travelling web e is also driven from a by means of bevil gear.
The web e is arranged so as to deliver the snow to the side where it does not
interfere with the traffic.
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. A. machine for removing snow on railways and tramways wherein endless
travelling chain buckets d carry the snow upward, and, when at the end of such
upward motion, have the snow removed therefrom by a snow clearing device such as c,
substantially as described with reference to the drawings.

page_text: 2. In a machine for removing snow such as is referred to in the preceding claim,
constructing the chain buckets without a bottom or with a hinged bottom, and with
a slot on their outer sides to allow of the passage through them of the revolving snow
clearer c substantially as described.
