10 Claims.

This invention relates to air translating apparatus and more particularly to devices for circulating air in rooms of buildings and the like.

In the accompanying drawings, I have chosen to show the invention as embodied in a window ventilator of the type adapted to be arranged adjacent an opening defined by a partially raised window sash and the window sill, and operable to admit clean and fresh, outside air into a room and to move the air about the room and mix the fresh air with room air, thereby producing comfortable living conditions. It is to be understood, however, that my invention in 'all of its aspects is not to be considered as limited to window ventilators, for in so far as certain of its broader aspects are concerned, it may be embodied in other types of devices used for' circulating air in rooms and the like.

One object of my invention is to provide an improved form of air circulating device wherein air may be directed at will to different desired portions of a room.

Another object ,is to provide an air circulating device of the character referred to, having an improved form and arrangement of louvers and also an improved operating means therefor, whereby the air may be simply and easily directed to dsired portions of a room.

The invention consists in the novel construction and combinatonof parts, to be more fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed.

In the accompanying drawings, to be taken as a part of this specification, I have fully and clearly illustrated a preferred embodiment of my invention, in which drawings:

Fig. 1 is a plan view illustrating a Window ventilator constructed in accordance with the present invention and showing the ventilator as mounted in position adjacent an opening provided by a partially raised window sash and the window sill of a window;

Fig. 2 is a front elevation of the construction shown in Fig. l;

Fig. 3 is a transverse vertical section taken on the line 3-3 of the Fig. 2;

Fig. 4 is a longitudinal vertical. section taken on the line 4--4 of Fig. 3;

Fig. 5 is an enlarged fragmentary vertical section taken on the same plane as Fig. 3 and illustrating the'various positions of the louvers which control the air outlet in the front wall of the ventilator;

Fig. 6 is an enlarged fragmentary verticalsec- (ci. eis-94) tion taken on the same plane as Fig. 4 and illustrating more clearly the detailed construction of the front wall louvers and their operating means;

Fig. 7 is an enlarged fragmentary horizontal sectional View taken on the line 'I-l of Fig. 6 and illustrating the louver operating lever and the connections between the lever and the louvers;

Fig. 81s an enlarged fragmentary sectional view similar to Fig.` 5 and taken on the line 8-'8 of Fig. 7;

Fig. 9 is a longitudinal. vertical sectionalview taken on the line 9-9 of Fig. 3;

Fig. 10 is an enlarged vertical sectional view similar to Fig. 3 and showing a modified form of my invention; Y

Fig. 11 is a longitudinal vertical sectional view similar to Fig. 4 and illustrating the modified form shown in Fig. 10. l. "n e Referring now in detail to the accompanying drawings and to the modification shown in Figs. 1 to 9, inclusive, it will be observed that I have shown my invention in one form as embodied in a window ventilator which is indicated generally by the reference numeral Ill.v 'I'he ventilator is shown as being removably positioned' with its rear side adjacent an opening Il which is defined by a lower sash rail I2 of a window, a window sill I3 and the sides I4 of the window casing (see Fig. 3). The ventilator rests at its rear on the window sill I3 and is suitably supported at its front by a pair of diagonal brackets I5, the latter being secured respectively at their upper ends to supporting strips I6 extending transversely beneath the ventilator and being secured at their lower ends to socket members ll'carried by that portion of a wall I8 of the room which is beneath the window sill I3. Suitable blocks 5 serve to close the spaces between the sides of the ventilator and the sides I4 of the window casing.

The ventilator I0 includes an enclosing casing structure I9 which is rectangular in shape, yas

shown, and extends longitudinally of the window opening II. The casing includes a rear wall which is provided with an inlet opening 2| extendthereof.

A partition 21 divides the interior of the ventilator longitudinally into a rear inlet chamber 28 communicating through the lter 22 and the inlet 2| with the outside atmosphere, and into an outlet chamber 29 communicating through a front wall outlet 24 and a top wall outlet 26 with the room (see Fig. 3). The partition 21 in transverse verticalvsection resembles a question mark and comprises a vertical lower portion 30 arranged in spaced parallel relation with the front wall 23 of the casing, an intermediate diagonal portion 3| extending upwardly and rearwardly from the top of the lower portion 30, and an upper deflecting portion`32 curved upwardly and forwardly from the top of the diagonal portion 3| to the top wall 25 of the casing and to a point above the lower end of the diagonal portion.

Removably mounted within the casing, is a mechanism which provides for the flow of clean fresh outside .air through the ventilator and the outlet openings 24 `and 26 into the room. k'Ihis mechanism is shown to be in the form of a motordriven blower unit indicated in general by the reference character 35 and including a motor 36 arranged centrally of the casing I9 and having a shaft 31 extending out both ends of the motor and longitudinally of the casing. The unit 35 also includes a pair of blowers 38 arranged respectively at each side of the motor and comprising housings 39 and centrifugal blower elements 40 arranged respectively in the housings and fixed to the ends of the motor shaft 31. The housings are provided with inlets 4| communicating with the inlet chamber 28 and outlets 42 communicating through symmetrically arranged openings 43 in the diagonal portion 3| of the partition 21 with the outlet chamber 29.

The motor driven blower unit 35 and partition 21 maybe rigidly secured together and removed as a unit from the ventilator casing. 'Ihese elements aie supported by al channel-shaped supporting member 44 extending longitudinally of and supported by a horizontal bottom wall 45 of the ventilator casing. The member 44 is detachably secured to the bottom wall by bolts 46 and wing nuts 41.

The upper deecting portion 32 of the partition defines, in conjunction with the diagonal portion 3|, a part of a tortuous passage for the air through the ventilator. Other portions of this passage are defined by the rear surface of a longitudinally extending damper 48 when the latter is in open position, which is the position shown in full lines in Fig. 3. 'Ihe damper is secured at its upper end to a shaft 49 extending longitudinally of the ventilator. An operating lever 50 for the damper is secured to an end of the shaft 49 exteriorly of the casing. The closed position of the damper 48 is indicated in dotted lines and, when in this position, flow of air through the casing is prevented. The interior surfaces of the outlet chamber 29 are lined with a suitable sound deadening or absorbing material indicated at 5|.

The details of construction and the arrangement of the motor-driven blower unit 35, the partition 21 and the damper 48 form no part of the present invention, they having been disclosed and claimed in the copending application for United States Letters Patent of Henry S. Woodruff and Paul T. Engelskirchen, Jr., SerialvNo. 31,584, filed July 16, 1935.

According to the precent invention I provide an improved form of louver means in thefront wall 2,081,104 extending for substantially the full length outlet 24 which may be adjusted when in one extreme position to direct the air upwardly and forwardly of the ventilator, to direct the air downwardly and forwardly of the ventilator when in another extreme position,.and to'close the outlet when in a mid-position. I also provide an adjustable louver means in the top wall outlet opening 26 which is operable to direct the air upwardly and rearwardly toward the window sash and wall of the room when in one extreme position and to close the outlet opening, when in the other extreme position.

This arrangement-of louver means is of particular advantage in an air circulating device where it is desired to direct the air to -different portions of the room for producing proper circulation conditions therein and when it is desired to prevent thecreation of objectionable drafts.l

For example, when the air entering a window ventilator such as I have disclosed, is substantially below the temperature of the air in the room and the introduction of such fresh air into the room through the outlet opening 24 in either of the directions provided for may be objectionable to the occupants of the room, the adjustable louver means in the outlet 24 may be closed and the adjustable louver means in the top Wall outlet 26 opened. With such an adjustment, 'fresh air will then be directed upwardly and rearwardly and toward the window sash and wall of the room and be diffused upwardly and forwardly into the room, thereby effecting adequate -circulation of fresh air and room air without creating objectionable drafts.

As stated previously, the outlet 24-in the front wall 23 extends for substantially the full length of the casing. The outlet 24 isv divided in the middle by a narrow vertical strip into a pair. of rectangular shaped openings 6I and 62. Arranged within each of these openings is a set of louver plates 63, each plate extending longitudinally across the opening and being arranged in spaced parallel relation with respect to the other plates in its respective opening and being -ar-` ranged in alignment with a corresponding plate in the other opening.

, Each of the plates 63 is shown as being pivotally mounted at its end opposite the strip 60 by means of rivet pin 64 extending through aligned openings in an end wall of the louver plate and in an inwardly directed flange 65 which defines the openings 6| and 62. Each of the louver plates is pivotally mounted at its end adjacent the strip 60 by means of a pin 66 extending through aligned openings in an end wall of the louver plate and in the flange 65. The pins 66 are relatively longand extend longitudinally behind the strip 60 and serve as pivotal supports for the adjacent ends of corresponding louvers in the openings 6| and 62.' The rivet pin 64 and pin 66 of each louver plate 63 are in alignment, thereby providing for pivotal movement of the louver plate about axes which are shown as being substantiallycoincident with the respective longitudinal center line of the A plates.

The arrangement of plates and pivotal mountings therefore, just described, is such that the 8, the plates and their pivotal mountings are artoA - the side of the lever.

provided with aligned openings, which receive the ranged in their respective openings so that when in closed position, a slight clearance $1 is provided Vbetween adjacent longitudinal edges of plates, thereby providing for pivotal movement of the plates in either direction from their closed position. One extreme open position of the plates is shown in full' lines in Fig. 5 and the other extreme open position of the plates is shown in dotted lines in Fig. 5. Figures 3 and 8 indicate the closed position of the louver plates.

I also provide for the operation of the plates 3 in unison. 'I'o this end, the end of each plate which is adjacent the vertical dividing strip lh is provided with an inwardly extending ange SB which serves as an operating element for the plate. A link S9 connects the anges d3 of each set of plates t3 for operation in unison. Pins 'it and li extending through aligned openings in the corresponding two middle louver plates e@ of each `opening di and 62 serve to connect the two sets of plates for operation in unison. As will be observed rom wg. 8, the pins Iii and ii also serve as a portion of the connection between the links Eil and their respective nanges et, each of the links de being provided with bent portions l2 engaging and rigidly secured to the pins 'id and 'il respectively by any suitable means such, for example, as by spot welding. Therefore, through pins lil and Il, the links d@ are operatively connected to the flanges dii oi the two middle plates b3 of each set oi plates.

In order to' provide for manual operation of the louver plates in unison from the exterior of the ventilator, I provide an operating device preferably in the form of a lever it which is iulcrumed on one of the pivotal pins E3, the latter also extending through an opening provided in the lever I3. The lever i3 is provided with an interiorly extend-u ing portion ld which is in turn provided on its cxtreme inner end with a slot l5. ing cross pin ll fits within the slot l5. The outer end of the' lever extends exteriorly of the casing and sprovided with a knurled portion 'l so that it may Ebe grasped by the hand and moved up or down to operate the louver plates V63 in unison.

In order to prevent the louver plates from being moved accidentally or dueto the force ofthe air and in order to hold the plates in certain selected positions, I provide at each side of the lever a spring pressed braking device 11 which engages the sides of the lever H3 (see Fig. '7). Each device l1 is provided with a base portion 18 arranged parallel to the rear side of the strip 66, a ange 19 engaging the inner side of the flange B5, and a flexible or resilient iiange 80 arranged parallel to the side of the lever and provided with a pressed out knob-like projection 8i engaging a relatively shallow arcuate shaped groove 82 in The anges i9 and 80 are pin 6E forming the fulcrum for the lever 13. The lever 13 is provided with openings 83 therethrough, at the ends and at the middle of the grooves 82 which receive the projections BI,

which openings serve to hold the lever and louvers in either of the two extreme positions and in the middle closed position. The resilience of the anges B results in the projections 8l being held tight against the lever in the grooves 82 at each side thereof and in preventing accidental movement of the lever between openings 83 and in holding the lever more positively in its extreme and middle positions. Y y

Frorr` an examination of Fig. 5, it will be observed that when the knurled end 16 of the lever The connect- 'I3 is moved downward, the louver plates 63 are moved in unison in a `counter-clockwise direction and provide for directing the air forwardly and the middle position of the lever being vthe closed position of the louvers.

The top wail outlet 26 also extends for-.substantially the full length of the ventilator casing and is divided at its middle by a relatively narrow horizontal strip @9, into elongated rectangular openings Si and 92. Arranged within each of the openings isa single louver plate S3 which is pivotally mounted to move about an axis extending longitudinally of the respective opening at the forward longitudinal edge thereof. The pivotal axes are provided by rivet pins Sil'extending through aligned openings in each end wall of the louver plates and in transverse nanges S depending from the top wall 25 at the end of the respective openings @i and 92.

I also provide a stop means for preventing movement of the louver plates 93 beyond their fjull open and full closed positions. This stop means is here shown as being in the form of a ange @S depending from each end of each louver plate 93 and provided with an arcuate slot 91 which receives a pin de extending from the adjacent flange 5 carried by the top wall 25. When the pin 93 engages either end of the arcuate slot el. the louver plate 93 is prevented from further movement. The full open position of the plates 93 is indicated in dotted lines in Fig. 3 and thc closed position in full lines. y

In Figs. v and' 1l. of the drawings, I have disclosed a ventilator la which is constructed and operates in substantially the same manner as the one of the previously described modicatlon, with the exception that in Figs. 10 and 11, I also provide an outlet Idil in the horizontal bottom wall dia of the ventilator extending for substantially the full length thereof. The outlet ll is divided in its middle by a strip I 0l into a pair of elongated openings 02 and |03, which are rectangular in shape and extent longitudinally of the vcasing lila.

Arranged within each of the openings l B2 and |03 is a louver, plate |04 which is pivotally mounted to move about an axis arranged at and parallel to the forward longitudinal edgebf its respective opening. The pivotal mounting is provided by rivet pins i 05 extending through aligned openingsin the end walls of the louver plates and in anges |06 extending upwardly from the bottom 45a at the ends of the openings H02 and w3. The full open positions of the louver plates are indicated in dotted lines in Fig. 10 and in full lines at the left of Fig. 11.

The outlet ld@ in the bottom wall and the adjustable louver means in the form of the plvoted plates IM serve as a means for directing the air from the casing downwardly and rearwardly and toward that portion of the rear wall lila of the room which is beneath the Window sill i3d, there-- by providing for directing the air into the room, in an additional direction which will be useful casing remote from said wall of the room and the other air outlet being in the top portion of the casing; means providing for the flow of air through the casing and through the outlets; adjustable louver means in said one'air outlet and operable in one position to direct the air to a desired portion of the room away from the wall thereof and operable in another position to close said one air outlet; and adjustable louver means in the .y
