5 Claims. (01. 98-114) This invention relates to a furnace outlet box and register.

In hot air furnaces, the pipes which carry the heated air from the furnace casing, in practice, extend laterally beneath the floor toadjacent vertical walls of a room which is to be heated and each is connected at its end to a box which extends upwardly through the floor and has a register closing either its upper end or an' open vertical side thereof, depending upon whether it is a floor register or a wall register, and with the register there is usually a pivotally mounted damper or louver whereby the openings through the register may be opened or closed to a greater or less degree and in this way govern the amount of heated air which passes into a room.

The present invention is directed to a very practical and economical construction of furnace'outlet box and register to be associated with the outer end of a warm air pipe from a furnace, to carry the heated air from said pipe to V anddeliver it into a room. One primary object and purpose of the present invention is to build the outlet box of two members identical in construction and one of which may be inverted with respect to the other, whereby the open ends of two members can be telescope'd together, providing a continuous box conduit for the warm air to carry the same upwardly from the end of the furnace pipe;

Another object of the invention is to provide each of said members at one end and at a side thereof with an opening so that the lower member may receive the end of the furnace pipe in said opening and the upper member be applied with a register of a pleasing and attractive de-' sign at said opening which will appear in the room to which the heated air is to be delivered. A still further object of the invention is to construct the outlet box of parts which can be very quickly and easily assembled at the installation, said parts being manufactured and shipped separately and so constructed that they may be nested so as to reduce the space required for shipment. Many other objects and purposes than those stated toegther with novel construction for attaining the same, all of which result in great economy of production and in. a design which is particularly adapted for large quantity production, will appear upon understanding of the invention, had from the following description, taken in connection with the accompanying drawing, in which, Fig. 1 is a fragmentary vertical section illustrating the manner in which the outlet box and register of my invention is installed in connection with the end of a furnace pipe.- 7 1 Fig. 2 is a fragmentary front elevation of the upper register portion of the unit.

Fig. 3 is 'a horizontal section on the plane of line 3--3 of Fig. 1.

Fig. 4 illustrates in perspective the various parts or elements which are used to provide one of the members of the construction, the parts being shown in disassembled relation and, in addition, the register to be used with the upper member of the assembly is shown.

Fig. 5 is a horizontal section, substantially on the plane of line 5--5 of Fig. 2, and

Fig. 6 is a vertical section illustrating the manner in which parts of the outlet box construction may be nested'together for economy of space.

Like reference characters refer to like parts in the different figures of the drawings.

In the-construction for the outlet box, each of the upper and lower parts of the outlet box includes a back member of thin-sheet metal having a vertical back 1, from which sides 2 are bent forwardly at right angles, and which at their front edges are formed with return bent flanges 3 extending from the lower edges of the sides 2 nearlyto their upper edges. This back member is completed by atop member of sheet metal pressed into the form shown and havinga back 4 curved and forwardly extended. Rounded and curved side and top portions 5 extend forwardly from the back 4, the lower edges of the back 4 and of the sides 5 embracing the upper por tions of the back 1 and sides 2 of the first de-- scribed member and being secured thereto.

The back member described is closed at its front lower portion by a front member comprising a vertical plate 6 with short sides 'I bent rearward- 1y therefrom which are rebent upon themselves to make flanges 8, permitting the plate 6 to be secured in place by slidably interlocking the

flanges

3 and 8 together. The upper end of the front 6 is cut away to provide a concaved recess and the metal is turned outwardly making a for wardly extending arc-shaped flange 9, whereby when the front 6 has been inserted in place there is provided at the up er end of the assembled box element a front circular opening, the lower portionof which is bounded by the flange 9.

Two of these box members may be connected together as shown in Fig. 1, the upper one being positioned with the front opening at its upper end and the lower one being inverted with the opening at its front side adjacent its lower end. The two members may be telescopically received one within the other and, as shown in Fig. 1, the inner end of the lower member telescopically enters the open lower end of the upper member, the lower member being crimped, as indicated at 10, to reduce its size sufficiently for telescoping.

When thus positioned, the opening at the lower front portion of the lower member may have the free end of a furnace pipe 11 inserted therein (see Fig. 1). The outlet box extends vertically from the pipe and the upper member is set back into a vertical wall 12 of a room, passing through an opening in the floor 13 between the room and the basement in which the furnace is installed, and the upper open end of the upper section of the outlet box is positioned so as to direct warm air, which passes upwardly through the outlet box, into the room.

When the construction is installed in a house and the outlet box has been attached to the furnace pipe, as shown in Fig. 1, with the outlet box vertically positioned and comprising the two iden-- tical members telescopically connected together, within the room and at the front of the upper member or section of the outlet box a sheet metal member is positioned having a vertical front plate 14 with sides 15 turned to the rear therefrom, the upper portions of which are formed as indicated at 15a (Fig. 4). The upper portion of the front 14 is cut away to provide a concaved recess around which an outwardly extending are shaped flange 16 is bent from the front 14. This member is placed against the front 6 of the upper section of the outlet box and moved backwardly thereagainst, bringing the curved flange 16 directly below the curved flange 9 of the member 6 as shown in Fig. 1.

One side 15 is longitudinally slotted, as at 17, for the passage of a damper or louver rod 18 which extends across between'the sides 2 of the first described member of the construction and has a sheet metal damper or louver 19 thereon within the upper section of the outlet box, whereby on turning the handle at the outer end of the rod 18, said damper may be moved to wholly or partly close the vertical'passage for the air through said outlet box.

A ring 20 pressed and formed into the shape best shown in cross section in Fig. 1, at its lower portion, passes around the flange 16 and covers the edges of said flange and the flange 9, and at its upper portion is located around the upper circular opening in the upper section of the outlet box. At its upper part it has a rearwardly extending apron 21 of sufiicient length to reach to the face of the wall 12, covering and surrounding the upper part 5 of the upper member'of the outlet box where the same extends forwardly beyond the inner face of the wall 12. This ring 22 is also formed with two ears 22 which lie fiat against the outer side of the plate 14. Openings through the ears, said plate 14 and through the front plate 6, permit the passage of rods 23, screw threaded at their inner ends, to have a threaded engagement with angle clips 24 permanently secured at the inner sides of the parts 2. The heads at the outer ends of the rods 24 are adapted to have a screw driver engage therewith to operate the rods and tightly draw the parts together. The opening, which is surrounded by the sheet metal ring 20, is adapted to receive a grille 26 stamped from sheet metal and of any suitable design, said grille having openings therethrough for the passage of air. This grille is pressed or snapped into place in the ring 20 as shown in Fig. 1.

In installing the apparatus wherever needed, suitable asbestos packing 27 is used, as between the part 21 and the part 5 as shown in Fig. 1, and between the sides 15 and the sides 2, as shown in Fig. 5, to preclude the escape of hot air except through the grille.

The construction described is of a very prac tical, economical, quantity production type. The two sections if the outlet box are made of parts having identical shape and form and may be constructed with the same dies. The nesting of a number of the largest elements of construction in the box, including the back 1, sides 2 and the back 4 and sides and top 5 is illustrated in Fig. 6, while of course the member which is comprised of the

parts

14, 15 and 16 may nest together, and the other parts are of a comparatively flat structure taking little space for shipment. The construction of outlet box may be completely assembled at the place where a furnace is to be installed. The register portion of the construction is much more economical to produce than the separate registers now commonly used in conjunction with furnace outlet boxes.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
