JOHN. sarees-ON, for New YORK, Y..
Letters Patent No. 106,348, dated' .August 16, 1870.
-mrnovzmzinr In FAN-Brownies.
The Schedule referred to in these Letters Patent undA making part of the Same.
T o all w1-tom 'it .may concern v Be it known that I, JOHN Enlcssox, of the city of New lYork, in the county and State of New York, have invented a new and improved'Fan-Blower; and
. I do hereby declare that the following is a full, clear,
and ,exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawing formingpart of this specification. f Y
Figure 1 represents a longitudinal section of'my improved fan-blower.
Figure 2 is a vertical transverse section ci the Similar letters of reference. indicate `coriespondiiigg; parts.
This invention relates to a new multiplying fanbloiver of that class in which a series of wings are rocated between a series oi' diaphragmsfor compressing the air by'centrifugal force, and utilizing itin the conipressed state for suitable purposes.
The invention consists chiefly inthe 'use of. a rotary case and stationary shaft instead oi' the rptary shaft and stationary cases heretofore employed.
The necessity of constructing the case in sections, so as to enablel the introduction of` the several wings that are mounted upon the shafts, is thus overcome,
and the case may be inadeinone single piece, and, consequently, nincb cheaper than the ordinary blowers now innse. y TheY ainoinit'ol' rotating. surface gained by making the case Irevolve addsalso considerably to the efi-` ciency of the machine. -v
A in the drawing represents the cylindrical case lor shell of vmy improved fan-blower.
'lh'is case is made of sheet-metal, orother suitable niateiial, and yis provided with heads aand b, whichy Vare firmly boltedor otherwisev secured to the body or the periphery of the case. f
'lhc head c, at the 'forward end, has 'a central opening, through which air is admitted to Ythe inte.
rior of said case. A
-The other head, @has a discharge-opening in the center. v
The shell or oase is hung upon a horizontal vlined shaft, B, on which it may turn loosely. 4
From the head @project arms c c, toward a sleeve d, which turns loose on the shaft B,'the said sleeve being provided with a pulley, e, crank or' gear-wheel,
for receiving the requisite rotary motion.
The other end of the case is provided with a projecting ilange, -f,vwhicli fits tightly upon a vcylindrical er conical llange or ring, g, thatprojects from a'box orreservoir, Cinto which the lcompressed air is discharged, thence to be conveyed in' suitable direction. 1
' outwardly.
' The shaft B supports the fixed ring or flange g, on which the flange f works tight, so that no air can esvcape between their surfaces.
Within the case A are arranged a. series of annular transverse diaphragme, 1th,ivliich are,a t their outer edges, secured to tli'e circumference of `the case. A
From' the inner face ofthe front head a, and also from the corresponding faces ot' the diaphragme h, project straight or ciii'vedwings or ribs t' t', which,
besides acting upon the air, serve. also to support annular plates jj, :is shown; t
The Outer edge Lof each plate j is some distance from the circumference of tbc case,- and in line with the outer ends of the wings t, its inner opening lits "close to thel shaft, or the sleeve! thereon.
.Between each pair of diaphragme 1i, and also between each head and diaphragm, is mounted, upon l the shaft B, a sleeve, l, which carries projecting wings m m, that reach about midway between the ends oi' the wings t' and the :circumference of the case A.
Around the outer ends lofeacli set'fof wings vmis fitted a ring, a, parallel with the circumference ci' the case, and this ring has a downward. projecting iangc or .annular plate, o, alongr the outer edges ol thc wings in.,
- As the.' case. A is revolved it will carry tiiediaphiagms It, wings .6, and plates j around' with it,"
.while the'vrings in, rings n, and plates I' o remain staj The rotary wings i create' suction,.ivhereby the air y will be drawn in through the central openings'in' the head .a and diaphragm It and thrownla inst the intemas ofthecese a. j ga vThe plates j confine the course oi air thus thrown The' air which is in contact with the case A is con fined in .the narrow space formed between the rings n and case, and thereby compressed, and can, in the-Y compressed state, be drawn toward the centergainby the action of the next set of wings i, which draw it down in the spaces between the plates o. and diaphragins h.
. The wings m serve also. to compress the air which may have been thrown against the innerfaces of-the .ring n, and to gradually guide such air 'toward the centegaiding thereby in producing the current ibi" the-air confined in the outer spacesbetween the case and the rings n.' In this mannerja perfect and rapid action on the air is produced. i
4 The centrifugalforcecrowdingfthe air against the periphery of the case A will aid lu tlioi'uifhly-compressing .the same, without retaining it, so securelv that 1t might not be drawn in again by the suction dt' the next set of wings i.
Having thus described my invention, I claim as new :md desire to secure by Letters Peteilt- 1. A fan-blower, provided with :L rotary fam on a. stationary shzft, substantially :is herein shown and described.
2. The rotating ense A, provided with the wings i.,
vdinphmgms h, and plates j, substantially :is I lerein shown and described.
3. The stationary wings fm, rings n, and plates o,
armnged to operate as set forth.
,an'anged on the stationary shaft within the rotating J. ERICSSON.
