1 Claim. (Cl

This invention relates to a heating and air conditioning unit. It has for one object to provide in combination in such a unit a chassis which includes the essential parts of the mechanism,

suchas blowers, humidiers, heaters, lters and A,

the like and includes the necessary structural members for their support so as to provide a unit chassis complete with the operation of a hood.

Another object is to provide a separate hood which may be removably mounted or secured to the chassis and to provide separable connection or latching means positioned partially upon the hood and partially upon the chassis.

Another object is to provide a method of assembly and installation of such a heating or air conditioning device.

Other objects will appear from time to time in the specification and claim.

The invention is illustrated more or less diagrammatically in the accompanying drawings, y

` 22 and 23.

structure with the apparatus in place but without the hood.

Figure 5 is a transverse view illustrating wall and building portions in section and showing the chassis positioned away from the wall and the hood positioned away from the chassis.

Like parts are designated by like characters throughout.

I indicates a wall of a building. A device may be installed in a partition and is not limited to the specific installation in a wall. As shown the wall is provided with an opening 2. A baille or shutter mechanism 3 may be provided in the opening 2. As shown a floor beam 4, may be provided. to support a iloor structure'5. A window opening is shown above the opening 2 and a window structure or assembly 1 is provided in it. Adjacent the opening 2 is a depression or hollow 8 formed in the wall or partition I and arranged to receive a portion of the unit.

The chassis of the unit is provided with a section or portion 9 which as shown, for example, in Figures 1 and 2 is both lower and narrower than the remaining portionof the chassis. This portion 9 is of such size as to fit into the space 8 when the chassis is in nal position in the wall.

While the details of the chassis and the assembly of the parts upon the chassis, might be widely varied they comprise in addition to the reduced section 9 above mentioned, a larger pornon which is both Wider and higher than the section 9. This includes a pair of structural .frame members It, laterally extending b-ack plate members Il, diagonal stiiiening braces or plates I2, iioor or bottom plates I3 and may include other structural members. In general, it is sufiicient for the purposes of this invention to provide such structural members as are necessary to form a self sustaining chassis frame. To these frame members are added, if desired, supports I4 and I5, which removably support various portions of the assembly. Preferably, the supports may be arranged to slidably receive the parts `which theycarry so that these parts are moved into place and may be removed just as drawers are pushed into or removed from their supports. The supports I4, for example, may carry a heating coil and the supports l5 may carry a frame member I6 of a blower assembly which includes one or more fans or blowers I1. As here shown, a set of supports I8 is provided and these supports may carry a lter I9. v Positioned below the supports I8, or made as a part of them if desired, are two plates 20 and 2I inwhich are provided respectively openings Dampers or doors 24 and 25 are arranged to close the openings 22 and 23 respectively. The dampers are opened by one or more levers 26 pivoted upon a support 2l. A pivoted connecting rod 28 joins one arm of the lever 26 to the damper or door 2li and a pivot connecting rod29 joins the other arm of the lever 26 to the door or damper 25. As shown, particularly in Figure 5, the arrangement of the parts just described is such that when the one door is closed the other may be open, or an intermediate position of adjustment may be used in which both doors are partially'open,

Although the particular invention herewith shown and described is not limited to the structural details shown, it Ais ordinarily'preferred to provide suitable openings in the frame and supporting members to permit the necessary electrical and"liquid connections. Thus, the plate members I5 may be perforated, as at 30, to per mit making of electrical connections with wall plugs or sockets. The members I3 may be provided with openings as at 3I to permit the making of liquid connections with sources of steam, water or drainage connections. The plates IIJ may also be perforated, as dat 32, to permit the passage of pipes 33. It will be noticed, in particular in Figures l and 5, that these passages are preferably elliptioal'or at least enlarged beyond the size of the pipes which pass through them.

Since the heating 'coil which lis positioned in register with the passage 32 is preferably inclined toward one end, the connections at the two ends of the heating coil are ordinarily not on exactly the same level. By the provision of an elliptical or enlarged passages it is possible to position the coil with its high end either to the right or to the left and this simplies the problem of assembly and installation.

As a means of closing or enclosing the chassis and the parts which it covers, there is provided a hood 34. This hood` is provided with end portions 35 and a top 36 which is cut away as at 31 and a grille 38 supported on members 39. While the hood may be of almost any shape itis preferably provided with rounded corners 40 as shown particularly in Figure 3. It'may also be provided with an ornamental band 4|.

As a means for removably securing the hood to the chassis a latch construction is provided. This includes a latch bar 42, provided with an oiset portion 43 intermediate its ends. Bearings 44 are provided for the latch bar and are positioned preferably on the front wall of the hood. The latch bar is provided preferably, as at either end, with offset latch portions 45, which may be moved into engagement with latch abutments 46 positioned in the form here shown on the chassis and inthe particular form herein shown positioned on the support members l of the chassis. As a means for operating the latch bar and moving it into and out of engagement with lthe latch abutment members 46 there is provided a pivoted member 41 which as shown is pivoted on the hood and preferably on its front Wall, and has an irregular shaped aperture 48. An operating shaft 49, may be removably inserted in the aperture 48 in the member 41 and is provided at its outer end with an operating handle 50. Alink 5| is pivoted at one end upon the member 41 and at its other end engages the offset portion 43 of `the latch rod 42. 'I'he handle E!! might be xed to the member 41 if desired, instead of being removable, as shown.

The hood may also be provided on its front Wall with an opening 52 corresponding in shape, in size and position to theopening 23 in the member 2|. A fixed grille 53 may be positioned in the opening 52 and may, if desired, be formed of 'inclined strips or slat members, as shown. On the inner face of the hood, with respect to the slats 53. are pivoted and downwardly hung iiap members 54. These tend to close in case of a sudden draft from inside of the device.

The useV and operation Vof the invention are as follows:

In general, the devicemay be considered as comprising an air treating apparatus. When it is to be installed it will ordinarily be installed at least vpartially within a wall or partition and a cavity or opening Will be provided, into which a part of the apparatus fits. Assembly of parts of the mechanism on the chassis and the making of Vconnections may be carried out as and when desired and convenient.

. The device may be put, first, not in but adjacent the opening in the wall. In the position shown in Figure 5 the chassis will be close tor the-Wall. The parts which are to be mounted v on the chassis may then or later be put in pla-ce, ifthey have not already been put in place. Preliminary connections may be made, and all of this done while the chassis is stripped or without the hood. Frequently it -is advantageous to keep the hood entirely away during the process of -assembly or installation to prevent damage to the hood.

When assembly of .the device is completed and it is seated in the opening provided for it and all of the connections have been made so that no further work remains to be vdone the hood is then put in position covering and surrounding that part of the assembly which does not lie Within the cavity in the wall and the whood is latched in position and afterward if it is desired to remove the hood for any reason, it is merely unlatched and the apparatus is then available for inspection or repair.

By the methods of assembly and installation aboveoutlined, the device may be treated as a chassis and during the period of installation, when the hood is most likely to be be damaged.' the -hood may be kept away and it is only after thework of installing the device is completed that the hood is installed. By assembling. the operative parts on a chassis without ornamental parts the operation of assembling is simplified and safeguarded.

'I'he modification of installation may thus be summarized as follows:

First the chassis with or without the parts which it is tofcarry will be placed close to, or Within, the cavity into which it is finally to be positioned., AThereafter whatever parts of the mechanism have not been installed will be added. 'I'he necessary electrical and fluid connections will then be made. These may be made before or after the ychassis has been moved into its final position. When the chassis has been put into final position; all parts have been mounted upon it and all connections have been made, the hood is removably positioned so as to cover all ofthe exposed parts of the chassis and the working mechanism which it carries.

I claim: Y

In combination, an air treating apparatus suitable for insertion in a recess in a fixed room wall, which recess is in communication with the exterior of the building of which the wall member forms a part, a chassis including a portion formed to penetrate the recess and a portion formed to abut Vagainst the inner face of the wail exterior to said recess passage, means on the chassis adapted for communication with a passage through the wall, a fluid connection between saidl chassis and said wall, said chassis being open on the portions away from said fixed room wall, supports on said chassis adapted to receiveoperating elements positioned upon said cha,ssisand inserted through said open portion thereof, and a removable housing for said chassis, said housing extending about andL above said chassis and enclosing the exposed portions thereof, and forming with said fixed room wall a complete closure for said chassis, said chassis and' said housing being both independently supported upon the floor of the room in which they aregloated, the fluid connection of the chassis constituting the sole connection between the chassis and the wall, said housing including air inlet and outlet passage elements aligned with appropriate portions of the chassis, means in said passage elements for controlling the passage of air therethrough, andV externally operable readily disconnectible means for securing said housing in relation to said chassis.
