Improvements in Snow Ploughs, Scoops, and the like.
GEORGE ERNEST MURRAY STONE Spring Bank, Upperthorpe, Sheffield
Student, do hereby declare the nature of this invention to be as follows:-
An improved shovel or scoop consisting of a peculiarly shaped plate of iron or
steel in combination with a wheel or roller, and a handle. For the purpose of
carrying out my invention I take a plate of iron, steel, or other suitable material
(preferably steel) of convenient dimensions and thickness, then by stamping or other
means I form the plate into an obliquely curved channel (called the blade of the
shovel) having two unequal sides or raised lips commencing at the forward edge of
the blade, the longer side or lip being continued in a gradually deepening curved
form round the back or rear edge of the blade and terminating at one side in such a
manner that when the forward edge of the blade of the shovel is applied to the
material to be moved (say for instance snow on the pavement) and held in position
at the proper angle as hereinafter described and then pushed forward, the snow
gathered on the shovel ascends between the raised sides of the blade and is thrown
out to one side, right or left as the case may be, by the peculiarly curved form of
the shovel above described. A like result may be effected by a modification herein-
after described. To the back or the underside of the shovel or scoop I attach a
suitable handle, or shaft or shafts so as to suit the convenience of the operator.
Also to the underside of the shovel blade I fix by means of a suitably formed sheath
or slide and within suitable bearings a wheel or roller in such a manner as to give
the required inclination to the shovel blade when held in position for use, and to
permit the shovel being easily pushed along the floor or pavement. The handle or
shaft if
may preferred be attached to the blade of the shovel by means of a hinge and
in that case the wheel or roller may be fixed to that part of the handle or shaft which
comes beneath the blade, so as to enable the operator to alter at will the angle of
inclination of the shovel. As above mentioned a modification in the construction of
the blade of the shovel may be made whereby instead of the curved part being
formed in one piece with the rest of the blade, it may be made moveable and
adjustable and attached to the straight part of the blade by a swivel or bolt in such
a manner as to render it capable of being turned to either side as required. It will
therefore be seen that when the shovel or scoop is pushed forward the snow, or
other material to be moved, which is gathered between the raised sides of the shovel
blade will, on reaching this curved part, be thrown out either to one side or the
other, according as the moveable part is "set" by the operator. A further modifi-
cation may be made so that instead of the shovel blade being curved as above
described, it may be made. straight, having lips or raised sides gradually deepening
from the forward edge of the blade towards the back thereof and provided with a
hole or socket for the swivel or bolt for attaching the moveable curved back, which
moveable back can be easily detached and the blade used without it. In this case
I provide a suitable contrivance for fixing a basket, box, or other vessel to the back
of the blade to enable the operator by simply pushing the shovel along the floor or
pavement rapidly and easily to fill the basket or vessel with whatever material he
may be gathering up.
The raised edges or sides of the shovel blade may be constructed deep enough to
allow them, when curved inwardly and toward each other to meet and thus form
the shovel blade into a kind of flattened tube for the purposes above set forth.

COMPLETE SPECIFICATION.
Improvements in Snow Ploughs, Scoops, and the like.
I, GEORGE ERNEST MURRAY STONE, of Spring Bank, Upperthorpe, Sheffield
Student do hereby declare the nature of this invention and in what manner th
same is to be performed; to be particularly described and ascertained in and by
the following statement :-
The chief object of the present invention is to furnish an apparatus or implemen
by means of which the clearing away of snow from pavements, sidewalks etc. may be
effected more rapidly and with less labour than heretofore..
The apparatus or implement hereinafter described consists of a peculiarly shaped
plate or plates of steel, iron or other suitable material in combination with a wheel
wheels or roller and a long handle, shaft or shafts. A rotary or revolving brush
also, if desired, be used in combination therewith.
In the accompanying drawings
Figure 1. is a side view of the apparatus showing the plate or "blade" having
both its straight and its curved parts in one rigid piece...
Figure 2. is a front view of the same.
Figure 3. is a back view, and
Figure 4. is a plan of the same.
Figures 5. 6. 7. and 8 are corresponding views of modifications of the apparatus.
Referring to Figures 1. 2. 3. and 4, 'A is the straight portion of the blade, B is
the curved portion, C is the wheel or roller, D is the handle or shaft.
'
In Figures 5. 6. 7 and 8 the same letters doubled refer to similar parts of the
apparatus..
..
Figures 9 and 10 are a plan and section of B B in Figs. 5. 6. 7 and 8.
Figures 11 and 12 show the method of applying a rotary or revolving brush for
usé in combination with the apparatus when so required.
"
For the purpose of carrying out my invention I take a plate of iron or steel or
other suitable material, preferably steel, of convenient- dimensions and thickness,
then by stamping or other means the plate is formed into an obliquely curved
channel shown at A B in Fig. 4, and called for convenience the "blade of the
shovel or apparatus, and having along each of its two unequal sides a raised lip a a. a. a.
commencing at the forward edge of the blade at a. a. the longer side or lip being
continued in a gradually deepening curved form bb. round the back or rear edge
of the blade and terminating at one side at b. in such a manner that when the
forward edge of the blade of the shovel is applied to the material to be moved (say
for instance snow on the pavement) and the apparatus held in position at the proper
angle as hereinafter provided and then pushed forward, the snow gathered on the
blade of the shovel is pressed upwards between the raised sides thereof and is
thrown out to one side-right or left as the case may be-by means of the peculiarly
curved form bb of the plate above described.
A like result may be effected by a modification hereinafter described and
illustrated in Figures 5, 6. 7.and 8.
To the back or underside of the blade of the shovel or scoop A is attached &
suitable handle or shaft D of a length and form convenient for the operator.
Also to the underside of the shovel blade I fix within a suitable frame or bearing
a wheel or roller C in such a manner as to give the required or proper inclination
to the blade when held in position for use and so as to permit the apparatus being
easily pushed along the pavement. The wheel-bearing or franie may be attached
to the shovel blade by means of rivets, bolts, or screws; or it may be fitted into a
suitably formed slot or sheath so as to be easily detachable if so required.
The handle D may, if preferred be attached to the blade of the shovel by means
of a hinge or hinged joint, in which case the bearing or frame of the wheel or
roller C may be fixed to that part of the handle or shaft which comes beneath the

page_text: blade A B so as to enable the operator to alter at will the angle of inclination of
the apparatus.
A modification in the construction of the blade of the apparatus may be made
whereby instead of the curved part being formed in one piece with the rest of the
blade, such curved part may be formed in a separate piece so as to be moveable and
adjustable, and in this case it is attached to the straight or rigid part of the
blade, or otherwise to the handle or shaft, by a swivel or bolt in such a manner
as to render it capable of being turned to either left or right side as may be
desired and as shown at B B in Figs. 5. 6. 7. and 8. For this purpose the straight
or rigid portion of the blade is provided with a projection, marked A A' in Fig. 8
to which the moveable curved part B B is attached by a bolt and nut N, to form
the swivel or joint on which such curved part may be turned about from side to
side. This curved portion is made triangular in shape having two of its sides
straight, and its base curved and turned upwards and inwards as shown in Figures 9
and 10. This triangular piece is provided on each of its two straight sides with a
hinged lip or flap of such dimensions that when raised into position for use. such
lip forms a continuation, to the required extent, of the raised lip of the rigid part
of the blade as is shown at B B in Figures 5 and 8. At the same time the hinged
lip of the adjacent side of the triangular part turned beneath the rigid part of the
blade is laid down flat as shown at B B' in Figures 7 and 8. The raised or
operative hinged lip or flap is held up in position by a smaller flap. hinged at
right angles thereto.
I do not however limit myself to this form of a hinged lip. The moveable lip
may be so constructed as to be detachable and capable of being readily put and
held in position by means of a lug and sheath.
Referring to Figures 11 and 12, F is the revolving brush pivoted to the handle D
at f. and having bevilled toothed wheels g g actuated by the wheel C. which has
for this purpose a suitable axle h., provided with bevilled toothed wheels kk as
shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. An apparatus or implement for clearing away snow from pavements, sidewalks,
and the like, consisting of a peculiarly shaped plate in combination with a wheel,
wheels, or roller, and a long handle or shaft or shafts substantially as herein
described and represented in the accompanying drawings and for the purposes
above set forth.
2. In a snow plough or shovel the application of a moveable curved plate sub-
stantially for the purposes above set forth and as herein described and represented
in the accompanying drawings.
Dated this 9th day of September 1892.
