VENTILATING APPARATUS.
Application filed October 21, 1909. Serial No. 523,851.
will so as to permit fresh air being admitted.
directly into the room or discharged there from, as may be desired. 4
The invention consists in the novel and simple construction of the apparatus, in the peculiar arrangement and combination of parts, and in certain details of construction, as will be hereinafter set forth.
In the drawings,-Figure 1 is a perspective view of an embodiment of my invention; Fig. 2 is an enlarged view in cross 'section of the outer end of the apparatus,
showing the application of the air filter; Fig. 3 1s a perspective view of the current directing mechanism; Fig. 4 is a detached perspective 'view of one of the cup members; Fig. 5 is an enlarged sectional view taken on line H of Fig. 1; and Fig. 6 rspective view of the filter.
In the drawmgsthus briefly described, A rep'e'sents the casing of the a paratus, compr ing an inner section B su stantially rectangular in form and adapted to rest upon the window sill, an intermediate section (3 designed to roject beneath the window sash and outwardly therefrom, and an outer end section D substantially rectangular in form having its bottom portion cut away preferably entirely, forming a passageway E for the entrance or discharge of the air. outer section is also provided with a swmging door F at its outer end adapted to swing outwardly, but held against inward movement fora purpose hereinafterset forth.
For forcing the air through the box I employ a fan G of anysuitable type and a motor H, and sup ort these preferably upon a standard I rig1 1y attached to the section 'B of the casing.
J represents an mtake pipe or conduit I leading from the fan downwardly to the air forwardly-extending ears or lugs box and communicating with the interior of the latter through its top, as plainly shown in Fig. 1.
-K 1s a similar pipe or duct leading upwardly from the box at a point adjacent the pipe J to the fan casing, forming the discharge conduit.
Within the interior of the box and arranged beneath communicating with the intake and discharge pipes respectively are cup-shaped members L and M, each having a portion of its side wall cut away to form a lateral passageway or opening, as O, the remaining portion of the side wall being lm-perforate and the section of the wall opposite the opening slanting upward. Each member is provided with an annular flange or collar, as P, which extends upwardly through the casin top withina complementary collar or ange, as Q, which forms a part of the casing, and the collar surrounding the intake conduit iscircumferentially slotted, as at a to permit of the extension therethrough 0' an operating handle b fixed to the cup. 1
The cup members described are mounted side by side upon the casing bottom for horizontal rotation, and are providedeach with a gear wheel, as c, which gears intermesh. he space between the cup members and the sides of -the casin means of filler blocks (1 e, an said members are arranged in close proximity so that the adjacent portions of their side walls abut the blocks and" cup members for a. partition extending transverse y within the front section of the air box, andbeing filter is 'desi ed to have a sliding fit within the section of the air box, so as to be readily removed and replaced when desired.
The fofward end of the air conduit is provided preferably with a spaced pair of U and deiiector pivoted between these, lu is a plate V, by means of which the draft of is closed by.
in area air through the box.
air issuing from the airbox may be. caused to pass downwardly in relation to the box or upwardly, as may be desired.
In the operation of the mechanism the motor is operated preferably by electricity, causing the fan to revolve and to discharge If it is desired to have the air pass directly within the room from the outside, the cup members are shifted through the agency of the handle I) so that the openings 0 in the members L and M communicate with the box respectively in the rear and'in front of vthe partition extending transversely of the box-formed by by the members ol, 0, M and L. Thus, air
, is drawn through the opening E and discharged into the room from the forward 7 L and M respectively in front and in rear of the transverse partition. The air will then be discharged from the rear of the box.
The air passing through the apparatus into the room necessarily passes through the screen or air filter, and is therebyclean'sed, while thedischargedair passes outwardly through the opening controlled by the door F, operating automatically to allow. of the dscharge and closing when air is entering 'the conduit, to cause its passage through the filter.
What I claim asmy invention is,
1.'In ventilating apparatus, the combina- I tion with a casing having inlet and outlet openings, of an air propelling device, intake and discharge ductsleading from said device tothe casing interior, relatively movable members within the casing formed eachwith an air passage, the passages registering with the air ducts and leading in diflerent directions, and means for shifting the-members to change the position of theair passages and the direction of travel of the air current through the casing.
