Improvements in Centrifugal Blowers and Injectors.
I MARTIN ROSE RUBLE of 764 Broad Street Newark County of Essex and State
of New Jersey U.S.A. Mechanical 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 this invention is to provide a blower or injector simple and
durable in construction, noiseless in operation and of great efficiency and also
to provide means for increasing its efficiency without increasing its speed or its
driving powers.
The invention consists in the improved blower and injector and its siphon, 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
claim.
Referring to the accompanying drawings in which like letters of reference indicate
corresponding parts in each of the two figures.
Fig. 1 is a front elevation of my improved apparatus, part of it being shown in
section and
Fig. 2 is a sectional view on line a, Fig. 1 the siphon not being shown.
In said drawings A represents a shaft adapted to be revolved by means of
pulley P. To said shaft is secured a flanged wheel b' serving as hub for the
revolving drum D, consisting of inner ring or cylinder h, outer cylinder or ring d,
and side walls d², d².
Within said drum are arranged one or more rows of radially extending tubes or
passages c, c, secured with their inner open ends in cylinder or ring b, and with
their outer ends in cylinder or ring d. These tubes or passages are preferably
made tapering towards the outer end and are provided with an elbow o¹, as shown in
the drawing.
The drum D is adapted to be revolved in chamber E, consisting of side walls e', e
and outer ring or cylinder e. The centre parts of the said side walls are provided
with openings e, e, and with flanges e, e which latter are adapted to fit within
cylinder b, thereby preventing an escapement of air or other fluids out of the
chamber E through its side openings eª e².
To the side walls e', e, of chamber E, are also secured bearings a¹ a' for shaft A,
but other ways of providing bearing for said shaft may be adopted. The chamber E
is also provided with one or more outlets f,f,f, f to which are secured by bolts
or in any desired manner siphons a-only one being shown in the drawings. This
siphon consists of a tube g', provided near its connection end g* with an enlarge-
ment or drum 9. Within said drum and tube is arranged a smaller tube /¹, closed
at the inner end, and provided with a branch tube h³, extending through the drum g³
of tube g'. The forward end of tube h' opens into the tube g
In operation, the inner drum D is revolved at high speed and, the air entering
through openings e, e, into the tubes or passages c, c, is thrown by centrifugal force
through elbows c', c', into chamber E and compressed therein. As the elbows
pass through the said compressed air, they produce at their outlets a vacuum, which
latter assist the centrifugal force-by drawing or sucking the air out of their
respective pipes into the chamber E.
As will be manifest there are two forces acting at the same time upon the air in
the tubes or passages c, c: centrifugal force and section force.
The purpose of providing the drum D around the tubes or passages is to reduce
their friction or resistance, when being revolved in the compressed air (or fluid) in
chamber E.
From said chamber E. the air passes through outlet ƒ (or ƒ¹ƒ'ƒ³ as the case

page_text: may be) into the siphon g and, in passing around the inner tube h', a vacuum and a
suction is produced at the outlet of said tube ', whereby the air is drawn through
branch tube and an increased blast is produced at the outlet of the siphon. My
improved apparatus can also be used for the purpose of drawing heat or smoke
from the smoke stack by connecting the branch tube with the latter, or it can be
used as a force pump for steam, water, gas or other fluids.
I do not intend to limit myself to the construction shown and described, as various
changes can be made without changing the scope of my invention.
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 :-
1). A blower or injector, consisting of a stationary chamber, and a series of
radial tubes or passages, adapted to be revolved within said chamber whereby by
means of centrifugal force-air or other fluids are conducted into said chamber,
substantially as described and set forth.
2). A blower or injector, consisting of a stationary chamber, a series of radial
tubes or passages, adapted to be revolved within said chamber and elbows secured
to the outer ends of eaid tubes or passages, and adapted to produce, when passing
through the air-at their outlets a vacuum and suction, substantially as described
and for the purposes set forth.
3). A. blower or injector, consisting of a drum or chamber, provided at each side
with a centrally located opening, an open cylinder arranged between said openings
and adapted to be revolved within said chamber and a series of radial tubes or
passages secured to and in said cylinder, and adapted to conduct air or other fluids
from said cylinder into said chamber, substantially as described and for the purposes
set forth.
4). A blower or injector, consisting of a chamber, provided at each side with a
centrally located opening, an open cylinder arranged between said opening and
adapted to be revolved within said chamber, a series of radial tubes or passages
secured to and in said cylinder and elbows arranged at the outer ends of said tubes
or passages and adapted to produce-when passing through the air-at their outlets
a vacuum and suction, whereby the air from the open cylinder is drawn into the
chamber, substantially as described and for the purposes set forth.
5). A. blower or injector, consisting of a chamber, provided at each side with a
centrally located opening, an open cylinder arranged between said openings and
adapted to be revolved within said chamber, a series of radial tubes or passages
secured to and in said cylinder, and a shell or drum secured to said cylinder and
surrounding said tubes the outer ends of the latter extending through the periphery
of said drum-all said parts being arranged and adapted to operate substantially as
described and for the purposes set forth.
6). A blower or injector consisting of a chamber, provided at each side with a
centrally located opening an open cylinder arranged between said openings and
adapted to be revolved within said chamber, a shell secured to said cylinder, and a
series of radial tubes or passages secured to and in said cylinder and extending
through said shell and provided at their outer ends with elbows, said elbows being
adapted to produce-when passing through the air-at their outlets a vacuum and
suction, all said parts being adapted to operate substantially as described and for
the purposes set forth.
7). A blower or injector, consisting of a chamber, provided with one or more
outlets, a series of radial tubes or passages adapted to be revolved within said
chamber and to produce a blast at the said outlets and a siphon secured to said
outlets and adapted to increase the said blast or pressure substantially as described
and for the purposes set forth.
8). The method of producing a blast or pressure by means of centrifugal force
acting upon the air contained in a series of radial tubes or passages secured to a
revolving air chamber, as described and set forth.

9). The method of producing a blast or pressure by means of centrifugal force
and suction force, acting upon the air contained in a series of radial tubes or
passages, secured with their inner ends to a revolving air chamber and provided at
their outer ends with elbows, as described and set forth.
10). In a blower or injector the combination with the outlet of a tube secured
thereto, a smaller tube arranged within said tube and provided at its inner end with
a branch tube extending at an angle through said surrounding tube, all said parts
being arranged and adapted to operate substantially as described and for the
