COMPLETE SPECIFICATION.
Improvements in Blowers or Fans.
I MARTIN ROSE RUBLE of Newark, County of Essex and State of New Jersey,
U.S.A. Mechanical Engineer my Post Office address being 764 Broad Street,
Newark New Jersey, U.S.A. do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of this invention is to provide a blower, simple and durable in con-
struction and of great efficiency.
The invention, which is an improvement on my application for Letters Patent for
"Improvements in Centrifugal Blowers and Injectors "filed March 19th 1892
No. 5475 consists in the new and improved construction of the air or fluid passages
and the combination and arrangement of the various parts substantially as will be
bereinafter more fully described and finally embodied in the clauses of the claim.
Referring to the accompanying drawings, in which like letters of reference
indicate the corresponding parts in the two figures,
and
Fig. 1, is a front elevation of my improved blower, part of it being broken away
Fig. 2, is a detail perspective view, plainly illustrating the mode of construction
of the air or fluid passages.
In said drawings a represents a shaft, adapted to be revolved in bearings a',
secured to the outer sides of the stationary chamber B, which latter consists of
the side walls bb, and the outer ring 6 with outlets g.
The said side walls are provided with centrally located inlets or openings 6 and
with inwardly extending flanges 6ª and are held together by bolts c or in any desired
manner.
Within the chamber B and secured to shaft a is arranged a drum D, consisting
of side plates d', and a series of triangular shaped chambers E between and bearing
against said side plates. Said chambers and side plates being securely fastened
together by bolts e, which latter bear against the inside corners of said triangular
chambers, as clearly shown in Fig. 1.
The side plates d', d³, are also provided with inlets or openings d and spokes or
arms d³ which latter serve as connection between drum D and shaft a.
Each of the said triangular chambers E is formed of one continuous strip of metal,
of uniform width standing edgeways between the side plates d', d, and consists of
the two radial (or approximately so) sides f. f, and the outer or segmental side fl.
The space between two adjoining chambers É serves as the air or fluid passages c',
through which the air or fluid is communicated into the stationary chamber B.
One of the sides of the triangular chamber E (in the drawings f*) is extended and
curved as at f³ and overlaps the segmental portion of the adjoining chamber, whereby
elbows or pockets c³ are formed.
Corresponding projections are secured to, or made integral with the side
plates d'd and from the side walls for said pockets.
The operation of the within described blower is the same as the one described in
my application filed March 19th 1892 No. 5475 whereby the air or fluid-when the
drum D is revolved-enters through openings, into the air or fluid passages,
and is thrown from there by centrifugal force into chambers B.
The pockets or elbows, when travelling through the air, produce a vacuum and
suction at their outlets, whereby the centrifugal force is assisted in conducting the
air out of the passages into the said chamber B.

page_text: 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 consisting of a stationary chamber, provided with centrally located
openings, and a drum, adapted to be revolved within said chamber, said drum being
divided into a series of triangular shaped chambers, and radial passages, whereby,
by centrifugal force the air or fluid is conducted through said passages into the
stationary chamber, substantially as described and set forth.
2.) A blower consisting of a stationary chamber, provided with centrally located
openings, a drum adapted to be revolved within said chamber, and a series of metal
strips arranged edgeways in said drum and adapted to form triangular shaped
chambers and radial passages within said drum, substantially as described and set
forth.
3.) In a blower, the combination with the stationary chamber, provided with
centrally located openings, of a series of triangular chambers, consisting of uniform
wide metal strips side plates d', d² holding said chambers, together and adapted to
form with said chambers, radially extending air or fluid passages, curved extensions
secured to or made integral with the sides of said triangular chambers and projections
secured to or made integral with the side plates d', a, said projections and extensions
being adapted to form elbows or pockets at the outer openings of the air or fluid
passages, all said parts being arranged and adapted to operate substantially as
described and for the purposes set forth.
Dated this 3rd day of May 1892.
