2 Claims. 1

The invention relates to air conditioning or ventilating apparatus for supplying air to a room or other enclosure and more particularly to those types of such apparatus that are adapted to take their air supply through a wind-ow opening.

The object of the invention is to provide a device of the character above described in which the intake duct may be installed between the opened window and its sill in the desired lengthwise position thereof and in which the motor driven unit is suspended from said intake duct in the desired position back of. the window sill, thus simplifying the installation of the unit and adapting it for use under conditions where a floor supported type of unit could not be used.

A further object of the invention is to provide valve controlled ventilator openings in the duct and in the unit to suit various conditions of operation of the apparatus.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a perspective view of an apparatus embodying the invention;

Fig. 2 is a vertical sectional view taken on the

line

22 of Fig. 1;

Fig. 3 is a horizontal sectional view taken on the

line

33 of Fig. 2;

Fig. 4 is a detailed vertical sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a detailed vertical sectional view taken on the line 5-5 of Fig. 3;

Fig. 6 is a detailed sectional view taken on the line B6 of Fig. 3.

The apparatus comprises an

intake duct

8 and a ventilator unit 9, means for mounting said duct between an opened window l and its sill II, and means for adjustably suspending the unit 9 from said duct.

The

duct

8 comprises a rectangular metal conduit open at its back end and having an inlet opening l2 at its front end covered by a screen l3, said duct having an

opening

14 in its bottom intermediate its ends adapted to be closed by a door or valve l pivotally mounted on a shaft l6 extending through the side walls of said duct and having an exteriorly disposed operating handle ll. Where the duct extends through the window opening, it is provided with a collar l8 of box section apertured to provide a channel section [9 with

side flanges

20 at its sides, and an angled

top portion

2|. The

duct

8 may be secured in any desired location lengthwise of the window opening, and for this

purpose blocks

22 of wood are sawed ed to a length which permits them to be fitted in the

flanges

20 at one end and to abut at their

other ends

23 against the

window frame

24 and be secured in this position by

nails

25 driven through the tops of said sections [9 and into said blocks. Finishing

strips

26 of sheet metal are cut to a length to fit between the duct and the sides of the window frame and are formed to provide an outwardly extending flange 21 extending from their reversely bent

top edges

23, which flange has a. downwardly projecting

watershed portion

29. The

strips

26 are firmly held in assembled position with the

blocks

22 by the

nails

25 which also pass through their flanges 21 as shown in Fig. 5.

The ventilator or air conditioning unit 9 includes a rectangular or

square box

30 of sheet metal whose front has an

opening

3| therein to telescopically receive the rearwardly projecting

end

32 of the

duct

8 and whose

opposite sides

33 adjacent the bottom have

air outlet openings

34, each of which have an adjustable valve or

damper

35 associated therewith, each damper being mounted on an adjusting

rod

36 pivoted in the front and back of the box and having an exteriorly disposed

operating handle

31. The front side 38 of the box is flanged and removably secured to the main body of the box by screws passing through said flanges and the

sides

33 so as to permit ready assembly of the parts within said box.

Within the box and adjacent the

opening

3| an

angled metal frame

39 is secured adapted to receive a

filter element

40 and intermediate the ends of the box a

metal spider

4| is secured thereto Whose

central ring portion

42 is adapted to receive and support an

electric motor

43 whose

shaft

44 carries a

suction fan

45 of any suitable type.

Between the window I!) and the unit 9 the duct rests on a

block

45 mounted on the stool portion of the window sill. The portion of the

duct

8 extending rearwardly from the block forms a beam or cantilever support from which the unit 9 is suspended, and this unit being slidable on said duct may be moved lengthwise relative thereto to accommodate difierent sizes of window stools. The

box

30 is preferably provided with lengthwise extending angled ledges 41 welded or otherwise secured to the

sides

33 thereof upon which the bottom portions of the inwardly projecting portion of the

duct

8 may ride during the adjustment of the box relative to said duct. The box is moved lengthwise relative to the duct to bring it adjacent the window stool, and its posi- 3 tion relative to the length of the duct being obtained, the lower side of the duct is cut away to form the opening 48, see Figs. 2 and 3.

With the above arrangement, the apparatus may be installed so as to bring the unit 9 over or adjacent one side of a heating radiator within the room to be supplied with air and so that air taken in from the outside by the

fan

45 will flow from one of the

openings

34 out over the radiator and the

other opening

34 will direct unheated air into the room, so that by adjusting the position of the

valves

35 for these openings the desired blending of heated and unheated air may be obtained. The valve controlled

openings

34 permit regulation of the volume of air delivered by the apparatus and obviated the use of a variable speed drive motor. Also for recirculating air within the room the opening of the

valve

15 will allow the

fan

45 to draw the air from the room itself and expel it again through one or both of the

openings

34. Where the device acts as a plain ventilating unit, the

filter

40 may be omitted.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. In an apparatus of the character described, the combination of anintake duct adapted to be mounted between an opened window and its sill and having an open end portion projecting inwardly beyond said sill, means for clamping said duct between the window and said sill, an air circulating unit including a box-like metal walled housing having inlet and discharge openings and a motor driven fan in said housing, that portion of said duct projecting from said sill projecting into said inlet opening and into said housing for a distance at least half the length thereof and forming a beam from which said unit is entirely suspended.

2. In an apparatus of the character described, the combination of an intake duct of less width than the window and adapted to be mounted be-- tween the open Window and its sill and having an open end portion projecting inwardly beyond said sill, a box-like member through which the inlet end portion of said duct projects resting on said sill and providing side pockets, wooden blocks mounted in said side pockets and abutting the sides of the window frame and finishing strips extending from said duct over said pockets and block and having flanges projecting over the upper portions of said pockets, and means passing through said flanges, the upper portion of said pockets, and said blocks to secure these parts in relatively fixed position and position said intake in the desired lengthwise location relative to the window opening, a block adjacent the inner edge of the stool of the sill upon which said duct rests, and a ventilating unit connected with and suspended from that portion of said duct projecting beyond said block and sill.
