PROVISIONAL SPECIFICATION.
Improvements in Rotary Fans Actuated by Electricity.
I JOSEPH ARTHUR WADE of 23 Huntley Road Fairfield near Liverpool in the
County of Lancaster Engineer do hereby declare the nature of this invention to
be as follows :—
An appliance whereby an impetus is given to electric motor fans for the purpose
of starting such fans when in any position. Such appliance consists of a lever
attached to the outer or stationary ring of the said fan and having a jointed end so
formed as to come, when required, into contact with studs fixed at intervals in the
outer edge of the wheel of the fan, such jointed end being retained in position by
means of a spring & peg. The said lever is retained in position ready to bring
into contact with the aforesaid by means of a spring and has attached to it a cord
or wire which on being pushed or pulled causes the jointed end of the lever to
come into contact with the said studs thereby giving an impetus to the said wheel
of the fan and causing it to move or revolve. On the pressure being released from
the said cord or wire the said lever returns to a position necessary for the next
operation.
Dated this Seventh day of June 1893.

COMPLETE SPECIFICATION.
Improvements in Rotary Fans Actuated by Electricity.
Joseph ArthuR WADE of 23 Huntley Road Liverpool 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 :-
The nature of the invention is an improvement in the mode of starting or
assisting to start rotary fans actuated by electricity which are hereinafter called
"the fans."
At the present time the fans, when in a certain position, cannot be started by an
electrical current.
In that case an impetus must be given to the fan by some physical force and a
push with a stick or by the hand is the mode of starting generally adopted.
My improvement consists in an invention for giving the necessary impetus to
start the fan when in any position by pulling a cord, wire or other similar appliance
which works upon a lever in the manner hereinafter particularly specified.
The improvement consists of the following pieces viz. :-
(a) A metal lever about of an inch thick and large enough at one end to reach
from a pivot on the stationary part of the fan or fan frame to a projecting stud
described under heading E fixed into the rotary part of the fan and long enough
at the other end to gain the necessary leverage hereinafter mentioned.
Such lever must have a joint measuring about the length from the pivot to the
end which when fixed will be nearest the rotary part of the fan.
The joint is made by means of a loose piece on set screw with a set screw stop
to prevent the loose piece turning back and a spiral spring one end of which is to
be affixed by means of a screw or soldered or otherwise on the lever close to the
pivot and the other end of spring to be affixed to the end of the loose piece nearest

page_text: the pivot. This spring is for the purpose of holding the loose piece against the
stop until a pressure is applied on under side.
The lever is to be bored with a small circular hole to receive the pivot (next
described). This hole is to be situate at such distance as will allow the jointed end
to come in contact with the projecting studs.
The lever referred to is more particularly described in Figures 1. 2. & 3 in the
drawing annexed hereto and therein marked A.
(b) A metal pivot of a length sufficient to keep the lever clear of the rotary
portion of the fan (except the studs) having a nut at one end to prevent the lever
coming off. The said pivot is to be affixed to the stationary part of the fan frame
or the fan at a point sufficient to allow the jointed end to come in contact with
the projecting studs.
The pivot as to its shape and place is particularly described in Figures 1. 2.
and 3 in the drawings annexed hereto and therein marked B.
(e) A metal spring with one end fixed on outer or unjointed end of lever and the
other end fixed to the fan or fan frame in such a position when the spring in
contracted the jointed end of the lever will be held in a position clear of the
projecting studs on the rotary part of the fan and on being extended will allow the
jointed end of lever to move and come in contact with projecting studs and move
the rotary part of the fan.
The said spring is particularly described in Figures 1. 2 & 3 in the drawings
annexed hereto and therein marked C.
(d) A cord chain wire or similar connection attached to the outer or unjointed
end of lever as shewn in Figures 1. 2. and 3 in drawings annexed hereto and therein
marked F.
(e) As many small projecting studs as may be required according to the diameter
of the fan are to be fixed in on the rotary portion of the fan as near the extreme
circumference as convenient.
The nature of the studs and the place where same are to be fixed are more
particularly described in Figures 1. 2 and 3 in drawings annexed hereto and therein
marked E.
The manner in which the improvement has to be performed is as follows.
When the lever is fixed in the manner before indicated and the projecting studs
duly fixed in the rotary part of the fan the spring described under description (c)
holds the lever at such an angle as to support the jointed end clear of the projecting
studs but when the lever is actuated on by the cord or other means the jointed end
of lever moves and is brought into contact with the projecting studs and by
pressing these gives an impetus necessary to alter the position of the rotary portion
of the fan.
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.
My improved lever for starting fans actuated by electricity together with the
pivot, spring and studs appurtenant thereto substantially as described herein and in
the Figures 1. 2 and 3 inclusive hereinbefore referred to.
Dated this 3rd day of March 1894.
