of material, which will occupy a minimum amount of space, and which is readily arranged so that the inlet and outlet pipes thereof may be at difierent levels and at different angles to one another.
I attain my object by means of'the constructions hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a vertical section of a fuel saving attachment constructed in accordance with my invention;
, Fig. 2 a similar view showing a slight modification of the same; and
Fig. 3 a cross section through the form shown in Fig. 1. V r
In the drawings like numerals of reference indicate corresponding parts in the different figures.
l'is a closed cylinder of sheet metal set Through the openinder 1. With the upper end of this pipe communicates a smoke inlet pipe 3 and'the smoke outlet pipe 4. These two pipes may be in axial alinement as shown in Fig. 1, or one may extend laterally from the upper end of the smoke pipe 2 and the other from the top thereof as shown in Fig. 2, though various other arrangements are of course possible. I
Extending from the side of the cylinder 1 near the top up to the smoke outlet pipe 4: is the smoke pipe 5. This may either extend diagonally as shown in Fig. 1 or may be an elbow as shown in Fig. 2. A damper 6 of any ordinary type is located in the smoke outlet pipe between its point of connection with the pipe 2 and its point of connection as sar snr series..-
with the pipe When this damper 6 is closed, the products of'combustion arriving through the smoke inlet pipe 3 pass down the pipe 2, up through the annular spacebetween this pipe and the cylinder and through the pipe 5 to the smoke outlet pipe. 7
It is sometimes desirable to completely out off the pipe 2 from connection with the'inlet and outlet pipes when the damper (Sis,
opened. For this-purpose I provide in the plpe 2 close to its upper end a damper 7 by' 7 means of which this object may be attained.
Loss of draft due to eddying in the lower. part of the device which would otherwise occur isfthus entirely avoided. To control the draft of the furnace it is preferableto use 'a damper as close to the furnace as possible. For this purpose I provide a damper 16 in the pipe 3'. The device will however work to some advantage without either of the dampers 7 and 16. A clean out door 8 may be provided in the side of the cylinder at the bottom as shown in Fig. 2, though I prefer to provide the clean out opening in i the bottom of the cylinder and to close it by means of the cap 9 (see Fig. l) telescoping over a flange surrounding the clean out opening.
A r to lighten the heavy products of combustlon or to ventilate the apartment in which the device is located may be admitted through a pipe 10 which, when in position,
extends up within the lower end of the, smoke pipe 2 and preferably has a baffle or cap supported above its other end. This cap may communicate with an opening in the bottom of the cylinder controlled by a damper 12 as shown in Fig. 2. It may also be connected with the cap 9 as shown in Fig. 1, the opening into the pipe 10 in this case being inthe bottom of the cap.
For some purposes it is desirable to allow 7 cold air to enterthe upper part of the cylinder and I therefore provide the slide damper 13 for this purpose. If desired, a ringshaped sliding damper 14: may also be pro-v vided in the pipe 5 as shown inFig. 1.
I also find that this device may be employed to heat water for domestic purposes and for that-purpose I provide one of the depending parts, for instance the pipe 2,
with a water jacket 13 (see Fig. 1). Suitable inlet and outlet pipes 14 and 15 communicate with this jacket. It is also desirable to be able to vary the length'of the circuitous path through which the products of combustion travel to suit different furnaces or different conditions of draft. I therefore prefer to make the cylinder 1 and the pipe 2 telescopic with sleeved extensions 1 and 2. These extensions will usually hold in place by friction but bolts 17 may be employed if the c linder to a point a short distance above the bottom; a smoke inlet pipe communicatin with the upper end of the pipe; a laterally ex'ending smoke outlet pipe communiz in-gr with the upper end of the depending pipe, a sn'ioke pipe extending from the side of the cylinder near the top to the laterally extending pipe; and a damper in the laterlly extending poebetween its point of communication with the depending pipe and its point of communication with the pipe leading from the side of the cylinder.
2. A fuel saving device constructed asset forth in claim 1 in which an air inlet pipe extends through the bottom of the cylinder part way up-the depending pipe.
3. fuel sa ing device constructed as set 3th in claim 1 in which an air inlet pipe extends through the bottom of the cylinder part Way up the depending pipe, and a cenieal balile located above the upper end-of the air pipe.
A fuel saving attachment for furnaces 'ising a closed cylinder; a smoke pipe (one :ie with the cylinder extending down through the cylinder to a point a short dis tance above the bottom; a smoke inlet pipe ecmmuiL sting with the upper end of the i'lepending pipe; a smoke outlet pipe comnn'mieating with the interior of the cylin' der; and damper rontrolled communications whereby the products of combustion arriving throughthe smoke inlet pipe may be directed down the depending pipe or allowed to pass substantially directly to the smoke outlet pipe.
