My invention relates to improvements in Ventilating devices.
An object of the invention is to provide a simple, durable and inexpensive device readily applicable to a room structure and adapt-v edrnot onlyto expel air therefrom, but to replenish the room with fresh air from the outside.
Another object vis to supplyfa Ventilating device, as above, a single fan being employed in moving the air.
lV-ith the'foregoing andother objects in View, which will appear in: tlie, following description, the invention resides in ythe novel combination and arrangement of parts and in the details' of construction hereinafter described and claimed.
In the drawings, Fig. 1 is a vertical central sectional View 'of a device embodyingr my invention,I the same being illustrated as applied to a room and shown in connection with a c'oil bunker therein; `Fig. 2 is ahorizontal, central sectional view of the device; Fig. 3 .is anl elevational view thereof and Fig. 4 is a sectional view in detail taken the line 4-4 of Fig. l.
Referring to the drawings, A represents a room, the wall 10 of 'which is formed with a 'circular opening 11 therein. A tliimble l2 is fitted' in this opening as shown lin Fig. 1, said thimble having an annular back-plate 13 formedintegrally with the body thereof.
- A central conduit 14 is arranged axially of the thimble 12 and is yheld in place by attachment to said back-plate 18 in any suitable manner, such, for example, as casting said conduit integralwith said back-plate.
. This conduit 14 forms a' mounting for the `journal of a fan B, which journal in the present instance, embodies a motor 15y secured by means of brackets 16 axially of the -conduit 14. The motor shaft 17 constitutes the fan shaft in the present` disclosure and said fan consists of an inner series ofradial blades 18 and an .outer series of radial blades A Aring 20-encircling the tips of the blades 18 registers with the adjacent end of the conduit 14 and supplies a mounting for the outer-series of blades 19. The' lnner blades 18 are similarly pitched. So also are the outer blades 19, but 'the inclination `ofy said outery blades is reversed with respect to the inclination` of the/inner blades 18.
on tion, as herein disclosed, maybe made with-i The central conduit 1'4 leadstp any de sired point ina room, such, for e ample, as',
the ingress port 21 to the coilb nke'r C i1- lustrated in Fig. 1. The backed thimble 12 issupplied with pipes'22, 23, having valves 24, 25 at their.ends,'` said pipes being led to parts of the room as desired:
-With the fan B turning'in one direction,
air is drawn 'from ,without through the blades 18 and delivered into -the room through the conduit 14. Air is also drawn from the room through thepipes 22, 23,
thimble 12 and'fan blades 19, said air beingy thence expelled into thejouter atmosphere.
Turning in the reverse direction, air is drawn from the room, through ,the conduit 14 `and y blades 18, .thence is propelled into the'outer air. Accompanying this expulsion of a-ir from. the room is the replenishing of air thereto, the same traveling into the room through the blades 19, thimble 12 and pipes 22, 23. Adjustment of the valves 24, 25 provides for several or joint use of the pipes 22, 23, asvmay bel required.
Changes in the specific form'of my invenin the scope ofwhat is claimed withoutde-v parting from the spirit of my invention.
l Having described my invention, what I claim as new and desire to protect by Letters Patent is: I
In a device of `the class described, a fan` having an inner set of radial blades, a ring vjoined at its inner periphery to the tips of said blades, an outer set of radial blades joined at -their` inner ends to the outer periphery of the ring, said blades being adaptedto set up opposed concentric streams of air, said ring being wider from edge to edge than the zones occupied `by said blades and providing inside thereof a. i' duct for the Istream of air set up by the inner blades, and a companion duct for said last stream of air, said duct being of the same inside diameter as said ring and disposed edge toedge with respect thereto in axial alignment there-l l I with. y
In testimony whereof, I have signed my name tothis specification.
