COMPLETE SPECIFICATION.
Improvements in Ventilating Apparatus.
We, MARTIN ROSE RUBLE, and JEREMIAH VREELAND, both of 764 Broad
Street, Newark, County of Essex and State of New Jersey, U.S.A., Mechanical
Engineers, do hereby declare the nature of our 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 this invention is to provide a ventilating plant, simple and durable
in construction and of great efficiency.
The invention consists in the new and improved ventilating plant, its blower, and
ventilators, and the arrangement and combination of the various parts thereof,
substantially as will be hereinafter more fully described and finally embodied in the
clauses of the claims.
Referring to the accompanying drawings, in which like letters of reference,
indicate corresponding parts in each of the several figures.
Fig. 1. illustrates the improved ventilating plant, adapted for a building;
Fig. 2. is a front elevation of the suction blower, used in connection with said
plant;
Fig. 2 illustrates in perspective view the construction of the suction cups of said
blower;
Fig. 3. is a side elevation of Fig. 2;
Fig. 4. illustrates in elevation one of the ventilating wheels and
Fig. 5. is a sectional view on line x. Fig. 4.
In said drawings (Fig. 1.) A represents a blower, connected by tube B with
one or more ventilating wheels C. To the other outlet of the blower is secured a
tube D provided with a syphon E, the latter again with suction pipe F and
discharge pipe G.
When the blower is in operation, the air is forced through tube B into the
ventilating wheels (the operation of the latter will be hereinafter more fully
described); the air which passes through tube D, produces a vacuum or suction at
the outlet of said tube, whereby the foul or bad air is sucked through tube F into
the syphon and from there discharged through outlet G, as clearly shown by
arrows in the drawing.
This specially arranged ventilator plant requires a blower with steady blast, and
we have for this purpose designed the construction, shown in Figs. 2 and 3 of the
drawings, in which a represents a shaft, adapted to be revolved in bearings b by
means of pulley c.
To said shaft is secured a drum d, consisting of the side walls e and fand the
outer periphery or ring g. The latter again consisting of a series of metal strips h,
provided with the curved or cup-shaped portions h³, h³, arranged opposite each
other.
The side walls e and are provided with projections e', f', corresponding in shape
with the curved portions h', of metal strip and are adapted to form therewith
suction cups or chambers i, as clearly shown in Fig. 24 of the drawings.
The side plates e and f and the metal strips h are held firmly together by bolts k
or in any desired manner.
The side walls, e and fare provided with one or more openings m, to allow free
passage for the air, into the drum d.
As can be clearly seen from the drawings, there are also cup-shaped chambers
formed by the side walls e and f and the curved projections h³ of the metal

page_text: ocation, the drum is revolved in the direction shown by the arrow Hin
Fig. 2.
The (outer) cup-shaped chambers i, when passing through the air, will produce
at their outlets a vacuum and suction, thereby drawing the air through openings m
into the drum and from there through the inner cups and outer cups into the
stationary chamber M.
The air will accumulate in said chamber, and is carried from there through pipes
or tubes D and A, to the ventilating wheels and syphon respectively. The so
described suction blower, can also be used without a stationary chamber, and is
then generally placed outside of a building, and the openings m are then connected
through tubes with the inside, thus enabling the bad air to be sucked or drawn out
of the building and discharged into the outer atmosphere.
The inner cup-shaped chambers, which will practically assist the outer suction
cups, by catching the air inside the drum, can be dispensed with if desired.
The following is a detail description of the ventilating wheels, used in connection
with our improved ventilating plant.
In said drawings n represents a hollow tube, provided at its upper end with a
series of rectangular flanges o and air inlets p, arranged alternately with each
other.
The lower end of said tube is provided with a series of elongated slots q, and also
with a threaded pin r, the latter being adapted to receive an internally threaded
knobserving as bearing for the hollow ball t.
To the upwardly extending flange u of said ball, is secured a grooved wheel or
pulley and to the outer periphery-two or more radially extending tubes w,
provided at their outer ends with elbows y.
"
The pipe B connects the ventilating wheels with the blower.
When the pipe B is connected with the blower, the air from said blower is forced
through said pipe into the hollow tube n, and through slots q into the ball t, from
where it enters the radial tubes w, and based on the principle of the well known
turbin wheels, causes said ball to rotate; when the tubes are passing or cutting the
atmosphere, a certain vacuum or suction is produced, at their outlets, said suction
releasing the blower of a certain pressure or strain, as will be manifest.
As the inflowing current of air at the outlet of pipe B produces a suction,
additional air is siphoned in through openings p of tube n.
In case no steady air current can be obtained, for operating said ventilator, the
pipe B is left open (disconnected) and the ball t may then be revolved by means of
the pulley, or in any desired manner.
The revolving tubes w will, when travelling through the air, produce at their
outlets a vacuum, thus sucking the air through openings p and syphoning the air
through pipe B as will be manifest.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1-A ventilating plant, consisting of a blower, provided with two outlets, one or
more ventilating wheels, connected through a tube with one of the outlets of said
blower and operated therefrom, and a syphon connected to the other outlet of the
blower and provided with a suction pipe and a discharge pipe, all said parts sub-
stantially as described and for the purposes set forth.
2-A suction blower consisting of a revolving drum, openings arranged in the
sides of the drum and a series of cup shaped chambers, arranged on the outer
periphery of said drum and adapted to draw the air out of the drum, by producing
a vacuum and suction at their outlets, substantially as described and set forth.
3-In a suction blower, the combination with the shaft, of a drum secured to said
shaft and provided on its outer periphery with a series of cup-shaped chambers,
said chambers being adapted to draw or suck the air out of the drum, air inlets or
openings arranged in the sides of the drum, and a series of cup-shaped chambers

chambers on the outer periphery, all said parts substantially as described and for
the purposes set forth.
4 The method of producing a suction, consisting in revolving a series of cup-
shaped chambers, secured to the outer periphery of an air drum, substantially as
described.
5-The method of producing a suction, consisting in revolving an air drum, which

projecting portions of the side walls of said drum and the outwardly curved portions
of the metal strips, composing the periphery, and a series of cup-shaped chambers,

upper end with a series of inlets, and a pulley secured to and adapted to operate
said ball, all said parts substantially as described and for the purposes set forth.
7-In a ventilator, the combination with a blower, of a tube, provided with a
