LETTERS PATENT to Edward John Colston Fear, of Hampton Park, Redland,
near Bristol, in the County of Somerset, Gentleman, for an Invention of
ADDADATTO FOR MECHANICALLY OPERATING
IMPROVEMENTS IN MACHINER
PROVISIONAL SPECIFICATION left by the said Edward John Colston Fear
at the Office of the Commissioners of Patents on the 3rd June 1881.
EDWARD JOHN COLSTON FEAR, of Hampton Park, Redland, near Bristol, in the
County of Somerset, Gentleman. "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR MECHANICALLY OPERATING FANS."
This Invention relates to certain improvements in machinery or apparatus for
operating fans by mechanical means, the object being by the arrangement and
construction of parts to provide for the motion given to the fan being regulated as
may be required, and to secure the requisite noiselesness of the operating parts.
The mechanism is carried in a cup or boxing mounted upon a rod capable of
sliding for adjustment of height in a tube or pedestal mounted upon a suitable foot.
The mechanism for operating the fan or fans is carried upon a plate, and consists
of a "clockwork" consisting of a driving spring, a driving wheel mounted upon a
spindle. The driving wheel is in gear with a pinion on the spindle of a second
driver acting upon a double pinion in gear with a pinion on a shaft carrying a
crank or a bevil wheel or other driver, according to whether the fan or fans is or
are to be operated in a rotatory or in a reciprocating manner.
When the fan or fans is or are to receive rotatory motion the wheel on the cross
shaft is geared with a pinion on a spindle upon which the fan or fans is or are to
be mounted. When the fan or fans is or are to receive reciprocating motion the
crank of the cross shaft is provided with a link piece acting on a stud on a slotted
link mounted upon a centre on a lever arm, which slot of the link receives a stud
upon a cross sliding bar which thus has imparted thereto when the adjusting spring
is wound to tension a reciprocating motion. This reciprocating slide carries a rack
in gear with a quadrant or wheel mounted upon a spindle, which spindle carries an
arm or arms to which the fan or fans is or are attached, preferably by a slotted
end being provided to the arm into which the handle of the fan will be received.

page_text: The lover arm above described by being raised or depressed will lengthen or
shorten the throw of the link action upon the slide bar to regulate the beat of the
fan or fans. To stop the apparatus a pair of spring jaws fitted with a tightening
screw as a vice will be applied, within which vice jaws a portion of the cross shaft
before described will be received, and upon tightening of the screw the working
of the mechanism may be stopped or friction be applied to slacken the motion.
In connection with the aforesaid cross shaft a fly wheel is applied to regulato
the motion, and a spring is applied to the fan operating shaft to act as a recovery
spring at the end of the heat of the action.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Edward John Colston Fear in the Great Seal Patent Office on
the 3rd December 1881.
EDWARD JOHN COLSTON FEAR, of Hampton Park, Redland, near Bristol, in the
County of Somerset, Gentleman. "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR MECHANICALLY OPERATING FANS."
This Invention relates to certain improvements in machinery or apparatus for
operating fans by mechanical incans, the object being by the arrangement and
construction of parts to provide for the motion given being regulated as may be
required, and to secure the requisite noiselessness of the operating parts.
The mechanism is carried in a cup or boxing mounted upon a rod capable of
sliding (for adjustment of height) in a tube or pedestal mounted upon a suitable
foot, or the said mechanism may be placed in a box or casing at the foot, and be
-connected up with the fan by means of a rod or shaft sliding for purpose of adjust-
ment in a tube or pillar attached to the said box.
The mechanism for operating the fan or fans is carried upon a plate, and consists
of a "clock work" consisting of a driving spring, a driving wheel mounted upon a
spindle. The driving wheel is in gear with a pinion on the spindle of a second
driver acting upon a double pinion in gear with a pinion on a shaft carrying a
crank or a bevel wheel or other driver according to whether the fan or fans is or
are to be operated in a rotatory or a reciprocating manner.
When the fan or fans is or are to receive rotatory motion the wheel on the cross
shaft is geared with a pinion on a spindle upon which the fan or fans is or are to
be mounted. When the fan or fans is or are to receive a reciprocating motion the
crank of the cross shaft is provided with a link piece acting on a stud on a slotted
link mounted upon a centre or lever arm, which slot of the link receives a stud
upon a cross sliding bar which thus has imparted thereto when the adjusting
spring is wound to tension a reciprocating motion.
This reciprocating slide carries a rack in gear with a quadrant wheel mounted
upon a spindle, which spindle carries an arm or arms to which the fan or fans is or
are attached preferably by a slotted or forked end, and being provided to the arın
into which the handle of the fan will be received. The lever arm above described

page_text: by being raised or depressed will lengthen or shorten the throw of the link action
upon the slide bar to regulate the beat of the fan or fans. To stop the apparatus a
pair of spring jaws fitted with a tightening screw as a vice will be applied, within
which vico jaws a portion of the cross shaft before described will be received, and
upon tightening of the screw the working of the mechanism may be stopped or
friction be applied to slacken the motion.
In connection with the aforesaid cross shaft a fly wheel is applied to regulato the
the motion, and a spring is applied to the fan operating shaft to act as a recovery
spring at the end of the beat of the action.
In the Drawings, Figs. 1 and 2, Sheet 1, represents in side view and plan
respectively one construction of operating mechanism according to this Invention,
but without the boxing and telescopic stand.
"
A is a plate upon which the clock work" is mounted; B, the springs; C, the
driving wheel in gear with the transmission wheels to the spindle E which is the
crank shaft (in the case of a reciprocating movement being given to the fan); F is
the link connecting the crank arm to the adjustable slotted link G of the cross
sliding bar H, which will by the ratchet H' actuate a quadrant upon the spindle H',
and this spindle will receive and hold the fan. The movement of the crank arm
will give reciprocating motion to the bar II, and thence to the quadrant and fan
spindle. I is a pivoted lever arm which carries at I¹ the slotted link G, so that by
raising or depressing the arm I the stroke of the ratchet bar H will be varied.
K is a pair of jaws pivoted at K, and embracing the spindle of the crank shaft E;
the screw Lacts to tighten or loosen the grip of the jaws K and to check the
speed of the crank arm, but a screw brake block acting upon a wheel on the crank
arm would serve this purpose. The winding is effected from pin M.
Fig. 3, Sheet 2, represents in side view and partial section the construction of
apparatus, wherein the operating parts are contained in a boxing at the foot of the
telescopic fan support; Fig. 4 is a sectional plan nt a, b, Fig. 3.
Fig. 5, like plan at c, d; and Fig. 6 is plan of the lever and ratchet for winding,
and similar parts in these Figures are lettered to correspond with the parts already
referred to in reference to Figs. 1 and 2.
The crank E is connected by link F to the arm G, whereby is imparted to the
fan motion spindle M the requisite reciprocating motion. 0 are springs for
assisting the easy action at the turn of the stroke. The coupling P connects
the spindle N to the bar N¹, which is packed at N³, and fits the tube N³, and
the tube N telescopes in the main supporting tubo N³, the head of tubo N*
terminating in a flango provided with india rubber ring, upon which runs the
friction wheel collar No supporting the head of the turning tube N³, which said
head is provided with a slot and thread for screw cap N' for holding the end of
the spring Q of the fan. A fly and break wheel R is driven off the crank shaft by
tho india rubber band S, and T is a scrow break (a block or india rubber faced
wheel) acting upon the break fly wheel R. The crank pins may be movable in
slots in the arm to shorten or lengthen the stroke.
The outline U indicates an
ornamental case or covering of this or that kind. In connection with the recipro-
cating arm G and acting thereby is arranged a bellows case (not shown in the
Drawings), which bellows is at the opening corresponding to the nozzle provided
with a perforated sheet metal box, into which a sponge moistened with scent or
disinfectant compound will be introduced as desired, and by the action the bellows
in operating will distributo the scent or disinfectant into the surrounding atmosphere.
A tube may be carried from the nozzle or boxing of the bellows up through tho
hollow telescopic stem, and be discharged at the head of the apparatus.
In the plan of under plate, Fig. 6, V is a ratchet wheel on the spring spindle,
and arm W has at the inner end and eye which works around said spindle, and
outer end of arm is provided with scrow, or slot, or neck, to receive a long arm for
winding. The spring catch is pivoted at x1, and the curved faco Y serves as a
tripper for the tail of the spring catch to hold same out of action when machine is
running.

page_text: For punkah working two of these sets of motions will or may be arranged at the
end of a horizontal bar carrying the punkah, and being thus in a horizontal position
the winding of the machine will be effected by treadlo.
For large apparatus, instead of the spring motive-power, steam, gas, or other
power may be applied to the crank or rotary spindle.
Having now described the nature and particulars of my said Invention in such
wise that the same may be readily carried into practical effect, I claim,-
Firstly. The improvements in machinery or apparatus for mechanically operating
fans or punkahs by the addition to a clockwork or driving mechanism of tho
governing, regulating, and operating parts, as herein described, constructed and
operating as and for the purposes herein specified in reference to and shown by
respective Figures of the Drawings.
Secondly. In combination with the operating mechanism for fans, the telescopic
elevating rods and tubes with the antifriction rollers, and the elastic or spring
holders or attachments for the fans, as and for the purpose herein set forth.
Thirdly. In combination with the operating mechanism for fans or punkahs, the
crank or eccentric operating adjustable, as and for the purpose specified.
In witness whereof, I, the said Edward John Colston Fear, have hereunto
set my hand and seal, this Third day of December, in the year of our Lord
One thousand eight hundred and eighty one.
