1, SILVESTER KUSIBA, of Lemberg, Germany, Civil Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide a snow plough, more especially for use
on railways, and which will be more effective in use than those at present
employed.
The invention comprises a suitable snow shield of substantially wedge-shape
and preferably constructed of metal. This shield is suitably supported upon
wheels and adapted to be propelled by a locomotive.
The shafts, carrying the supporting wheels, are coupled by straps or the like
running over pulleys. The front shaft carries bevel gear-wheels which mesh
with like wheels on the rear extremities of forwardly-projecting shafts which
have pointed and screw-like vanes or cutters at their forward ends. The rotation
of these cutters break up the snow.
A second shield covers that aforo, referred to and is adapted to be reciprocated
vertically by excentrics upon the shafts or axles and connected to the shield by
rods. Spiral springs may encircle the rods between the two shields. The edges
of the reciprocating shield are flattened or flanged so that it beats down the
snow at the side of the plough and thus forms a solid embankment on each side
thereof.

page_text: In order to facilitate the penetration of the plough into the snow the propeller-
like shares or screws care provided which derive their motion from the axles c by
means of bevel gear d.
In order to obtain sufficient power to drive the shares or screws c¹ the axles are
coupled by endless bands e, chains and sprocket wheels, or other well known
coupling mechanism.
In order to prevent the piling up of snow on the top of the plough a second
snow-shield is provided which rests upon and partly covers the aforementioned
shield, and serves to loosen the drifted snow by means of its vertical reciprocating
movement. This movement is attained by eccentrics g levers, cranks, or the like
which are connected to rods h attached to the movable shield f by any well known
means. The back side can be closed by one or more hinged doors provided with
any suitable fastening. The shield can be provided with a pointed portion i
which serves to loosen the frozen snow. This shield also serves to beat down the
snow on each side of the track, its edges being flanged for that purpose as shown
at . Spiral springs may be inserted between the shields bf, as shewn, if
desired, to compensate for uneveness in the track.
Fig. 3 shews a symetrically built plough which divides the snow equally on teach
side of the track; but if it is desired to prevent the snow from being thrown onto
the adjacent track it is preferable to construct the plough as indicated by broken
lines.
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
I claim is
(1) In a snow plough of the character shewn and described, a snow shield open
only beneath and at the back and mounted upon wheels, substantially
described.
as
(2). In a snowplough the arrangement of propeller like shares or screws,
which deriving their motion from the supporting wheels by means of gear wheels d
serve to break up the snow, substantially as described.
. f
(3) In a snow plough, the arrangement of a snowshield, which by means of
eccentrics or cranks driven by the wheels a-and by reason of its arrangement &
shape serves to loosen the high lying snow and to beat it down on each side,
substantially as described.
(4) In a snow plough the arrangement of couplings, such as bands, sprocket
wheels, and chains, cranks and connecting rods or other well known means whereby
the driving power of the wheels a is combined to drive the propeller like shares or
screws e substantially as described.
(5) In a snow plough of that class described the general arrangement of parts
all substantially as described and adapted to be propelled by motors.
