AIR CONDITIONER Filed Dec. 30, 1933 3 Sheets-Sheet 3 INVENTOR DAN/EL L..5Bfl/N.
ATTO RN E Y5 Patented Aug. 13, 1935 UNITED STATES PATENT OFFICE My invention relates to. air conditioners and particularly to an air conditioner that may be set into a window opening.
The present application is a continuation in part of co-pending application Serial No. 663,932 filed April 1, 1933.
Objects of my invention are to provide an air conditioner by which air may be drawn from outside a building, filtered, mixed inselected proportion with air from the interior of the building and distributed into a room or building in a selected path; to provide an air conditioner that may be set into a window opening; to provide a maximum conditioning effect for a minimum opening of the window, and to provide a conditioner having few parts and that may be easily removed, taken apart and re-assembled.
Other objects of the invention will appear from the following description.
The various features of the invention are illustrated in the accompanying drawings, in which- Fig. 1 is a vertical elevation of an air conditioner embodying a preferred form of the invention taken from the interior side of the air conditioner.
Fig. 2 is a vertical elevation taken from the opposite or outside of the air conditioner.

Fig. 7 is a vertical sectional view of the air I conditioner taken on line 1-1 of Fig. 5.
Fig. 8 is a sectional detail view of a part of the air conditioner taken on line 8-8 of Fig. 7, and
Fig. 9 is a perspective view of a shut-elf orocntrol curtain forming a,part of the air conditioner.
In my invention the air conditioner is provided with a removable filter through which the outside air is drawn by means of a fan, and with dampers which admit air from the interior to mix with the filtered outside air and then tobe distributed by the fan to the interior of the room, The amount of outside air drawn through the apparatus is controlled by means of a shut-01f curtain actuated by thedampers so as to restrict the inflow of outside air progressively as the dampers are opened.
The entire apparatus is mounted in-acaslng or fixed louvre plates I 2, the size and number of 10 the openings being so selected as to provide a uniform distribution of air throughout the width and heighth of the chamber. A vertical filter I! of glass, wool or other fibrous material coated with a sticky material such as petrolatum, is supported between guiding grooves l4 and IS in the top and bottom of the chamber and so placed that the air admitted through the openings ll passes transversely through the filter toward the front or interior side of the chamber. through the filter IS, the air is drawn by means of a fan It, Figs. 1 and 6, mounted on the inner surface of the front wall l8 of a front'or interior member IS, the fan It directing the air through an outlet opening in the wall l8. The wall It is also provided with a. pair of inlet dampers 2|, one on each side of the fan It and outlet opening II, and tiltable about a horizontal axis 2 I to open and close suitable inlet openings in the wall l8.
Air from the interior of the room to be con- 80 ditioned may be drawn through the damper openings by the suction created by the fan 16 and, mixing with the outer air, is returned by the fan Ii into the interior of the room. The front or room side of the chamber III is provided with a 85 receiving groove 22 to receive the upper edge of the wall It and the upper edge of the latter is rounded as at 23 to fit the groove 22 and permit a motion relative thereto.
The member is is supported against the groove 22 and sealed in the chamber H) by means of a sealing strip 24 of rubber or other flexible resilient material set into a recess 25 in the bottom and side walls of the chamber l0 and pressing resiliently against a bottom wall 26 and side walls 21 of the member l9 so as to form an air tight seal around the bottom and side walls of the member 1!, while permitting the latter to swing freely about the groove 22. This arrangement also provides against vibration and noise.
Die swinging movement of the member I9 is limited by pins 30, one projecting from each of the side walls of the box ill to contact with the rear edge of the side walls 21 when the member I9 is swung backwardly into the box l0, and to contact After passing 20 with a hook 3| extending from the edge of the side wall 21 to engage the pin 30 when the member I9 is drawn forwardly or outwardly of the box It]. By removing the pins 30 the member It! may be drawn forwardly untilits rear edge clears the front edge of the box It) and then it may be lowered to free the upper edge-23 from the groove 22. The interior of the box i is then freely open for inspection or repair and the rear of the front member I9 is also-open for inspection and repair.
As the member 9 is tilted about the edge 23, the fan It is correspondingly tilted and the current of air propelled by the fannormal to the front face of the member I9 is tilted. upwardly to a greater or less angle with the tilting of the member l9. The air propelled by the fan l6 may consist entirely of air drawn from the room for recirculation therein, or may be air drawn entirely from the outer atmosphere through the filter '.|3, or may be mixtures of air from these two sources in any desired proportion. When the dampers 2| are closed, all of the air supplied by the -fan|6 will enter through the-inlets H, pass through the filter |3 into the interior of thebox l0 and then be propelled by the fan l6. When it is desired to recirculate only the air within the room without an admixture of air drawn through the filter I3, the dampers 2| are opened wide until theygeach a horizontal position. In moving to this position the dampers serve, through a link 32 connected at one end to the lower'part of the dampers, to swing the scoop 33 having supporting arms 34 connected to the'link' 32 andpivoted .at their upper ends on pivotpins 35 on the side dotted lines in Fig. 5, thecurtain 36 is stretched upwardly from the plate 31 at thelower edge of the filter l3 and forms, with the scoop 33, a barrier to the passage of air forwardly from the filter l3.
It will be understood, of course, that the curtain 36 together with the scoop 33 may not necessarily form an air tight closure with the side and top walls of the box l0, but will form a substantial obstacle to any considerable passagevof outside air to the fan l6. The curtain 36 may be formed of any suitable material such as canvas or other fabric or, if desired, of flexible metal construction or of flexible composition material.
When the damper 2| is moved ,to closed position, the scoop 33 is drawn forwardly by the link 32 until it overlies the lower wall 26 of the member IS, the front part of the curtain being drawn between the lower edge of the scoop 33 and the upper face of the wall 26 so as to form a fluid tight against the lower wall of the box In although,
preferably, it will take this position when the member [9 is tilted outwardly to its maximum position. When tilted backwardly or into the box II], the curtain 36 will bulge upwardly slightly,
as indicated in Fig. 5, but this will not form any substantial obstacle to the passage of air.
The connection between the link 32 and the arms 34 is by means of pins 38, one on each arm' means such as the arms 48 (Fig. 6).
may be operated and controlled through an elec- 34, passing through a slot 39 on the link 32 so that the damper 2| may be swung from closed to vertical. position, indicated in broken lines in Fig. 5, before the front edge of the slot 39 engages the pin to tilt the scoop. This enables the damper 2| to be opened somewhat without closing the curtain. Further opening of the damper 2| serves to proportionately close the curtain and proportion the inside and outside recirculating air.
The filters |3 are preferably of a replaceable type and are inserted through an opening in the side wall of the box ll), which opening is provided with a door or cover 40 shown in Fig. 4. This door isformed of a solid plate or sheet of metal and has vertical flanges 4| to fit into vertical grooves at each side of the filter opening, and a top flange 42 fitting into a top groove in the box. This provides a substantially air tight closure. When the filter I3 is removed from the box lo the curtain holding plate 31 is freed and may be removed with the curtain when the front member I9 is removed.
As illustrated in Fig. 3, the box l0 may be held on a window sill 43 by the engagement of a window 44 in a receiving groove 45 (Fig. in the upper or top wall of the box It). An adjustable foot 46 is provided to support the box on a window sill of any shape or pitch. Adjustable or replaceable side members 41 are also provided on the box In to enable it to fit windows of difierent widths.
It will be noted that the box l0 and the member H! are of about the width of the window sill and that the lower edge of the sash fits into the narrowest part of the box In so that all of the window opening area is free and available for the passage of air, while the box I0 may extend upwardly to the upper edge of the frame portion of the window giving a maximum area of flow through the filter l3 without obstructing any of' the light area of the window.
It will be understood that the fan l6 will be preferably of a noiseless type mounted on the front Wall of the member I!) by any suitable The fan trio switch 49 mounted on the. front wall of the member I9.
Through the above invention, therefore, an air conditioner is provided that may be readily placed in the opening of a window Without obstructing the light, and this air conditioner efiectively purifies incoming air and tempers it with recirculating air in any desired proportion. The various elements of the invention are simple in construction and may be readily taken apart so as to give access to the interior of the apparatus for replacement or repair.
