CASING FOR BOILERS HEATER UNITS, AND

AIR CONDITIONING UNITS Mora s. Hall, Westminster, Ma, assignor to May l(ililluginrner Corporation, a corporation of Mary- Application October 8,

i 2 Claims. The invention relates to improvements in casing construction, particularly in casings for en-.

closing boilers, heaters and air conditioning units. More specifically the invention relates to casings for enclosing automatically fired boilers, heaters and air conditioning units.

In the recent development of the heating and ventilating art, the use of automatically fired apparatus has promoted the usaof the room or the space, in which the heating or air conditioning device is located, for recreational, living or other purposes and anobject of the present invention is to provide, a suitable casing to enclose the device in such a way as to conceal unsightly, irregular forms and to present an attractive, decorative and comparatively symmetrical appearance.

Casings of thistype are generally bulky and '7 awkward, and are expensive to ship and to handie, if assembled before shipping, so that another object of the invention is to provide a finished casing such that it can be assembled at the place where it is to be used, without the use of special -tools or special skill.

parts shall be readily and quickly accessible for,

purposes of service and repair, a further object of the invention is to provide a casing comprising panels without hinges or catches, supported in a frameworkof suitable strength 'and rigidity, of which the wall panels may be separatly, quickly'and easily detached from their position in the framework without the need of any tools and o'f-which panels, any one or more may be removed from its position without displacing or disturbing otherpanels. v

Asit is frequently desirable-to heat insulate heating or air conditioning units, more or less fully, still another object is to provide a casing of panelled form in which'the panels are domountable and adapted to receive heat insulation of the casing with parts cut away showing the 1936, Serial s. 104,121 (01. 220-4) panel construction and the manner in which the panels are set up in theframework.

Fig. 3 is a fragmentary perspective view showing the casing framework from the outside at one corner, the parts being disassembled and separated from each other and some broken I away so as to show construction of various framework members.

Fig. 4 is a fragmentary perspective view of the casing framework from inside at one corner with the various parts assembled, some being broken away to-show construction."

Figs. 5, 6, '7 and 8 are reduced elevational views of the four sides; namely, end, front, rearand other end, respectively, of 'the'casing panelling showing the disposition of the panels and-the openings for smoke pipe and boiler connections.

Fig. 9 is a perspective view showing front, top and one end of a casing adapted for use with an air conditioning unit showing air inlet and outlet ducts.

In the drawings like reference characters indicate like parts throughout.

The invention may be described as comprising an enclosing casing open at the bottom, having atop and side walls and a rigid, adequately strong framework of shaped metal parts held together by screws or bolts, the framework having a rectangular box-like conto and having its parts adapted to receive remo able, abutting, top and side wall panels.

The casing comprises a framework having top and

bottom rail members

20 and 2| on each of the four sides and corner posts members 22 at the four corners. The top and bottom members are joined by suitable top and

bottom gusset members

23 and 24, respectively, (Figs. 3 and 4) which serve not only to join the respective members but also as spacer members so as to facilitate assembly with the cdrner posts 22 and the top and

bottom corner pieces

25 and 26, respectively. The corner posts are set up in the space provided between the rail ends when joined by the gusset members and are held in place by means of the top and bottom corner pieces, the parts being joined together by screws.

It will be noted that each of the various parts, top and bottom rails, corner posts, top and bottom corner piecesand gussets -are all stairdardized for the particular casing and that the parts,

tion so that a minimum of dimculty is experienced in putting the framework'together. This interchangeability'of parts permits the framework to be shipped in knock-down condition and erected on the site where used, around the boiler or heater, and as there are no other fastening members except small screws or bolts, the whole may be set up with a small screw driver and wrench so as to provide a strong and rigid structure.

to the place of use and is conveniently set up around the heater, the bottom rails resting directly upon the floor upon which the heater stands.

The lower rail member 2| of the framework comprises a Z shaped portion 30 and an L shaped portion 3|. One leg of the L shaped portion forms the bottom of the lower member upon which the casing rests, the other leg extends vertically upward and forms the outwardly disposed portion 32 of the lower member; one leg of the Z shaped portion is fixed by spot welding or by other fastening means to the inner face of the L shaped portion at its angle so that the web 35 of the Z shaped portion extending horizontally, inwardly and its other leg 361 extending vertically, upwardly, form, with the remainder of the upwardly extending part of the L shaped portion, a channel 38 with which the lower ends of the panels, to be described later, interfit freely.

The upper rail framework member 20, comprises a channel shaped portion 45 with the channel disposed so as to extend vertically downward and an L shaped portion 4| with one leg spot welded to the channel shaped portion so that the other leg 42 of the L shaped portion extends horizontally, inwardly and forms an inwardly extending shelf upon which the cover panels are supported.

The lower rail members are joined at the corners in spaced relation, so as to permit the corner posts to be fitted into place, by means of gusset members 24 which are held in position by screws; the upper rail members are likewise joined at the corners by the gusset members 23.

The vertical corner posts comprise formed metal molding members 22, with outwardly concaved round corners 46 and flanges 41 extending outwardly on either side of the corner so as to present outwardly disposed faces in planes perpendicular to each other and in the plane of the outwardly disposed wall panel faces when in place. These flanges on either side are bent again inwardly at right angles 48, to the previously mentioned flange faces. The flange faces 48 provide a smooth surface abutment at either side of the corner posts which abutment lies adjacent to the vertical end panel edges when in place in the casing. The corner posts made up as described form a rigid, strong corner of the framework.

The corner posts and bottom rails are joined together by means of the bottom corner members 26 which are all provided with holes for the insertion of screws or bolts by which the parts are held together. The corner posts and top rails are joined together in a similar way by means of suitably shaped top corner members 25 and are also fastened together by means of screws. The corner members are made so as to provide a somewhat ornamental finish to the framework.

The wall panel members for the four sides 5|, 52, 53, 54, 55, 56, 51 and 58 are: made of sheet metal of suitable gauge and are provided with inwardly extending flanges 6| on the lower edge and on the two vertical edges, the flanges being at right angles to the panel faces. These flanges The framework in disassembled state is taken are bent inwardly once more at right angles at 52 to the flanges 6|, the flanges 62 forming a retaining flange for sheet-form heat insulation ma- The flanges being omitted from the terial 63. top edge of the panel permit the insulation material tobe slid into place from the upper end from which. the flanges are. omitted and to be retained in place by the flanges around the other three sides of the panel previously described. This arrangement of parts permits ready renewal or replacement of the insulation material and the flanges also serve to stiffen and to strengthen the panel.

The channels in the upper and lower rail members and the flanges SI of the panel are made to interfit. The panel dimensions and the upper and lower rail members are proportioned so that the channel 40 in the upper rail member is twice the depth of the channel of the lower rail channel member 38. The panel members are of a length which equals the length of the open space between the upperand lower channel members plus slightly less than twice the depth of thelower channel 38. The panel is provided with a louver 6 which also serves as a hand hold. In order to place the panel in its position in the framework of the casing the upper margin of the panel is inserted in the upper rail member channel and raised until it clears the lower rail member and then the lower margin of the panel is brought into registry with the lower rail channel and dropped into the place in the lower channel. The side wall panels are all inserted into position in the same way and in any order desired and any one or all of them may be removed and put into place again at will as required Without the use of any tools at all; Fig. 2

shows'one of the wall panel members being placed in its position.

The top covering panels 10, H and 12 are formed with doubly, inwardly extending flanges 13 on all four sides and are merely supported by the inwardly extending flanges 42 forming the shelf portion extending inwardly from the top number of standard sizes of panel members by.

merely providing various suitable lengths of top and bottom rail members.

The panel members are provided with additional louvers 15 where required and with necessary openings 16, l1, l8, l9 and in certain panels where required for smoke pipe, controls or observation instruments and inlet and outlet connections as shown in Figs. 5, 6, '7 and 8.

The structure fabricated and put together as described herein provides a finished casing for the purpose stated which is shipped in knockdown condition and is assembled when and where used and which is possessed of the required rigidity and strength; which may be put together without special tools; and of which the panel members may be removed forinspection of the apparatus encased or for other purposes or which may be replaced at will without any tools and which may be varied in size by means of varied standard sized panels and rail members; in addition the form of the casings, and of the panels and framework, as well as the lack of need to do any material mechanical work on them while making the installation permits of decorative finish, painting, baked enamelling or plating to be done on the casings in the knock-down form and to be shipped as a complete article ready to be set up, with great economy of storage space, labor and shipping charges.

The casing may be used for air conditionin units, as shown in Fig. 9, by changing the arrangement of the cover panels to permit connection' with the intake BI and outlet 92 for the air to be circulated, similar frameworkand side wall panels being used, as are shown in Figs. 1 to 8 inclusive, and of a sizetosuit the installation.

.While I have described specific embodiments of the inventionwhich have been shownin the drawings, it is to be understood that the invention may be further modified as'to construction and arrangement of the several co-operating parts without departing from the spirit or scope of the invention.
