Complete Specification Accepted, 5th Feb., 1889
I, JAMES KIEVELL of the City of Hamilton, in the County of Wentworth, in the
Province of Ontario, Canada, Gentleman do hereby declare the nature of this invention
to be as follows:-
The nature of my invention consists of a perpendicular shaft provided with a
number of arms projecting out at right angles, these arms have V shaped blades
secured to the ends for the purpose of receiving the wind which causes the shaft
to revolve.
The foot of said shaft rests in a foot plate on a base which has four or more
standards with cross-arms on the top, the centre one of which acts as a steadying
bearing for the upper end of shaft; resting on the top of this bearing, and around
the top of the shaft, are four or more cross-arms with perpendicular bars suspended
therefrom, and held in position at the bottom by a ring. A rudder is placed on the
top of these arms which are rotated by the action of the wind upon said rudder.
The opening for the wind to revolve the shaft is on the opposite side of machine
to rudder, of which opening a part is closed by a shield opposite to the convex of the
blades; and the other part opposite to the concave of the blades, is provided with a
door to admit a full or part force of wind against the blades.
In the accompanying drawing:
Fig. 1 is a side elevation of a machine, showing only two blades with arms.
Fig. 2 is a plan of the machine with the top mechanism removed to show fully the
arms of shaft with their blades.
Similar letters refer to similar parts throughout the several views.
The base a with its four standards b, cross-arms & with their centre as a bearing
for upright shaft d; constitute the frame-work of the machine.
The perpendicular shaft d in foot bearing is provided with a number of arms e,
each set of arms being a distance apart; the lower arms are connected to the upper
arms by the blades c, and secured thereto by any mechanical device.
The machine, as shown, is operated by the wind coming from the east (as denoted.
by the arrow in Fig. 2).

The rudder attached to cross-arms g¹, rotates with the frame'; consequently the
opening in the shield J of said frame, on the opposite side to rudder and partially
covered by the sliding door J¹, is always open to the wind except when desirable to
stop the machine or to lessen the power, when the doors are fully or partially closed.
His a
ring to strengthen frame g, I is a knob or door J', and K is a wheel or pulley
on shaft to transmit power.
The doors may be hinged to the frame y (near the arrow, Fig. 2) if desirable; and
when open would act as guides to opening for the wind.

JAMES KIEVELL of the City of Hamilton, in the County of Wentworth, in the
Province of Ontario, in the Dominion of Canada, Gentleman, 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:-
The nature of my invention consists of a perpendicular shaft provided with a
number of arms having V shaped blades secured to the ends for the purpose of
receiving the wind, which causes the shaft to revolve. The foot of said shaft
rests in a foot plate on a base which has four or more standards with cross arms
on the top, the centre of which acts as a steadying bearing for the upper end
of shaft.
Resting on the top of this bearing and around the top of this shaft are four or
more cross-arms with perpendicular bars suspended therefrom, and held in position
at the bottom by a ring attached thereto.
A rudder is placed on the top of these arms, which are rotated by the action of the
wind upon said rudder. The opening for the wind, to revolve the shaft, is on the
opposite side of machine to rudder, of which opening a part is closed by a shield
opposite to the convex of the blades; and the other part opposite to the concave of
the blades, is provided with a door to admit a full or half force of wind against the
concave of the blades.
In the drawings left with the provisional specification,
Fig. 1. is a side elevation of a machine showing only two blades with arms.
Fig. 2. is a plan of the machine with the upper mechanism removed, to show fully
the arms of shaft with their blades.

page_text: The base a, with its four standards b, cross arms &, with their centre as a bearing
for upright shaft d, constitute the frame-work of the machine.
The perpendicular shaft d, in foot bearing 1, is provided with a number of arms e,
each set of these arms being a certain distance apart; the lower arms are connected
to the upper arms by the blades c, and secured thereto by any mechanical device.
The machine as shown is operated by the wind coming from the cast as denoted by
the arrow in fig. 2. The rudder r, attached to the cross arms g', rotates with the
frame g, consequently the opening in the shield J, of said frame on the opposite side
to rudder and partially covered by the sliding door J, is always open to the wind
except when desirable. to stop the machine, or to lessen the power, when the doors are
fully or partly closed. H, is a ring to strengthen frame g. I is a knob on door J',
and K, is a wheel or pulley on upright shaft, to transmit power.
The doors may be hinged to the frame if desirable, and when open would act as
guides to opening for the wind.
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;
1st. The combination of a perpendicular shaft d, in a foot bearing 1, and the bearing
in centre of arms 1, the said shaft having a number of projecting arms e, substantially
as set forth.
2nd. The combination in a wind mill of a rudder attached to rotary arms g¹, with
a frame g, having a shield with one or more sliding or hinged doors, and a perpendicular
shaft d, provided with arms and blades substantially as described.
3rd. The combination of a base a, having standards b, cross arms 6, the cross arms ¹
with frame g, having sliding or hinged doors, and the shaft d with its arms and blades,
substantially as described and set forth.
