Disinfecting, and other Purposes.
I, JACOB MCCONNELL of No. 109 Walton Breck Road, Liverpool in the County of
Lancaster, 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 object of my Invention is to produce a ventilating or air propelling apparatus,
reversible in action, and adapted for ventilating purposes generally, as also for warming,
cooling disenfecting, and other purposes, such for instance, as perfuming apartments.
In the device according to my Invention, the rotation of the propelling fans, is effected
by the flow of water, steam, compressed air, or other fluid, the pressure required being
exceedingly low.
In order that my Invention may be the better understood, I have appended the
accompanying two sheets of drawings, in which Fig. 1. represents an elevation of
the ventilator according to my Invention. Fig. 2 is a plan of the same. Fig. 3 is a
sectional elevation of the device, showing by the arrows, the passage of the air, and
Fig. 4 is a sectional plan drawn on the line A B, Fig. 3. Fig. 5. is a detached view
of the motor and fans; like letters of reference being used to indicate corresponding
parts throughout the several views.
In the construction of the device or contrivance according to my Invention, I
employ an outer cylindrical shell or chamber C, open at the top and formed preferably
of thin metal; a bottom L, of the same material, being soldered, or otherwise attached
hereto. Upon said bottom L is secured in any suitable manner a hollow cylinder, or
chamber, M, to the top of which is attached a vertical pipe N, closed at the top with
conical plug, or similar suitable device. A pipe I, terminating in a valve or cock,
ስ'

page_text: passes through the outer shell C, and communicates with the interior of the chamber M.
Upon the vertical pipe N, and loosely fitting it, is placed an outer tube, or sleeve O,
having attached thereto, two hollow transverse arms P P1, at each outer extremity,
of which is a small perforated nozzle a, a, Figures 3, 4 and 5. The vertical pipe N
is pierced with slots or holes bb', so that the steam, water, or other fluid within the
chamber M, and vertical pipe N may pass into the transverse arms P. P¹, and out
through the nozzles a. a'. Suitable fan blades Q. Q. Q. Q. are attached to the sleeve O,
shown more particularly in the detached view at Fig. 5.
An inner cylindrical vessel, or chamber, E, is fitted within the outer shell C, and is
provided with a removable cap F, and a perforated dise K., for the purpose to be
hereinafter described. A diaphragm S. is fitted within said vessel or chamber E, and
is provided with a central circular orifice T. An opening U, is formed in the side of
the vessel or chamber E., above the diaphragm, and exactly opposite to said open-
A handle c, or
ing U, is provided. a similar opening U', below said diaphragm S.
equivalent device, serves to turn the inner chamber E, freely within the outer
chamber C, so as to bring the openings U, and U₁, opposite the conical inlet and
outlet tubes D, and D', respectively, so as to reverse the action of the ventilator
when desired.
A hollow jacket K, surrounds the outer shell C. and is furnished with a pipe and
cock d for the purpose of supplying it with steam, hot or cold water or other fluids
as may be desired.
The method by which I operate the apparatus, according to my Invention, is as
follows that is to say:-
A low pressure of water or steam is supplied to the chamber M, through the cock,
and pipe I; the supply passes through the slots or holes b. b', in the vertical stem or
pipe N, into the hollow transverse arms P. P, issuing through the holes or nozzles a. a¹,
causing said arms P, P¹, and the sleeve O, to revolve, by reason of said water or steam
impinging upon the surrounding air. The fans Q. Q. Q. Q. are thereby set in motion,
and according to the position of the orifices U. U₁, in the inner chamber or vessel E,
air is drawn through the nozzle D into the vortex formed by the revolving fans, below
the diaphragm S, whence it is driven out by centrifugal force, through nozzle D¹.
If, however the inner chamber or vessel E, be turned round, so that the opening U₁,
is coincident with the inlet pipe D, and the opening U, similarly coincident with the
outlet pipe D', the latter becomes the inlet, and D the outlet nozzle, of the ventilator,
the fan meanwhile revolving in the same direction, as before the action of the
apparatus was reversed. The hollow jacket K, may be supplied through the cock H
with cold, or hot water, or steam, to raise or lower the temperature of the air discharged
by the ventilator. If the cap F, be taken off, and a cloth, sponge, or other suitable
material, saturated with perfume, disinfectant, deodoriser or the like be placed above
the perforated disc R, it is evident that a certain volume of air, charged with the
aroma of the above substances or liquids, will be drawn into the vortex of the fan and
will mingle with the air already drawn in through the opening U, which will be forced
into the building, ship, mine or other place, through the opposite opening U¹.
The power of the ordinary water service of a town, is sufficient to work the motor
above described, and contributes toward the heating or cooling of the moving air, by
reason of the splashing against the wall of the shell C, and dispersion thereof as it
issues from the nozzles a. a. The waste water or other fluid, is carried away by means
of the drain pipe J, fitted close to the bottom I. of the shell C.
In Figures 3 and 4 the direction of the current of air which is set in motion by
the fans Q, Q, Q, Q, is shown by the arrows; D¹, being the inlet and D, the outlet
pipes respectively, this position of the pipes being reversed however, by moving the
inner chamber or vessel E half a revolution by means of the handle c.
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
claim is
1st. The apparatus substantially as and for the purposes herein set forth.

page_text: 2nd. The construction of a reversible ventilator with appliances attached thereto
for varying the temperature of the current of air passing through said ventilator, and
varying the direction of said current at will substantially as herein set forth.
3rd. In a reversible ventilator the employment of a low pressure water or steam
motor, with fans attached substantially as and for the purpose herein set forth.
4th. In a reversible ventilator the inner cylinder or chamber E, with the
diaphragm S, and openings U, U, in combination with a disc or equivalent
substantially as herein described and set forth.
