Specification of Letterslatent. Patentd Aug. 3,
Application filed January 15, 1917. Serial No. 142,417,
To all whom it may concern:
Be it known that I,'ERwIN W. SEEGER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Stoves, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. I
My invention r lates to stoves and has for its object the provision of a stove which is adapted in its preferred form more particularly for heating small inclosures such as garages. My invention contemplates the provision of such a stove having in connection therewith automatic means for regulating the degree of heat given off by the stove.
In accordance with the preferred form of my invention I utilize a stove which is provided with an inclosing shell longitudinally thereof, the cold air entering the bottom of this shell and emerging at the top thereof, the regulatingv means being controlled by suitable appliances susceptible to the degree of heat of the air between this inclosing shell and the stove. In other words, the stove heats the air as it is passing through a duct and the temperature of the air in the duct controls suitable appliances to regulate the heating effect of the stove.
My invention contemplates in its prefer-red form a stove of this character in which the stove may be placed within the compartment or inclosure which it is to heat, and also contemplates a structure in which the interior of the duct aforesaid has no connection with the active fire or flame portion of the'stove, the stove being placed preferably exteriorly of the compartment. The duct then at its lower portion extends into the compartment and then again opens up into the compartment at the top thereof so that a circulation of air is caused by virtue of which cold air is drawn from the bottom of the compartment, this air being heatedin the duct and then led in the top of the compartment in'a heated condition, the stove which projects into this duct for heating the air being so associated with the duct shell that no portionof the flame or fire of th stove is in communication with the interior of the compartment. This is of a special advantage in connection with the art.
garages where the presence of an active flame or fire might cause explosions when gasolene fumes are presenttherein. I will explain these two forms which my invention may take morein detail by referring to the accompanyingv drawings, in wh1ch Figure 1 s a s de view of my improved stove show ng the inclosing shell partly in sect1on;,
Fig. 2 is a sectlonal view of the stove and shell along a plane at right angles to the plane of the paper when taken inconnection with Fig. 1;
Fig. 3 is a top view of my improved stove; Fig. 4 is an enlarged'detail view showing the regulating mechanism; V Fig. 5 is an enlarged fragmentary view showing the manual control mechanism Fig. 6 is a side view partly in section showing my stove as applied exteriorly of the compartment which it is to heat, and
Fig. 7 is a frontview of the stove structure shown in Fig. 6'.
Referring more particularly to the structure shown in Figs. 1 and 5 inclusive, I have a stove 1 that is provided preferably with a magazineQ, which magazine is closed by the cover or lid 3, the stove having at its lower portion a grate 4 overthe ash'compartment 5. 'The stove has at its lower portion a mouth 6 through which the *ashesniay be removed, this mouth being covered by a screen 7 normally when the ashes are not being removed to prevent ignition of any gases which might be in the compartmentwithin which the stove is placed. This mouth is covered by the ash pit door 8 and the opening of this door 8 of course controls the duct 1n connectlon with other devices presently to be explained, as is customary 1n door with the controlappliances, as will presently appear. The stove has at its upper extremity a stack 10 through which-the products of combustion pass, this stack being provided with a suitable damper'll adapted to control the heating effect of the stove, this damper '11 being connected through the agency of a suita'bleplink 12 with the control A suitable chain 9 connects this appliances to be presently explained. "The stove in its entirety'as thus explained issurrounded by a shell 13, which shell is rounded at the top as shown at 14. This shell may be preferably supported upon legs The shell thus is open at the bottom and open at the top,' forniing an annularchamber about the stove for heating the airwithin this chamber. The cold air of course enters at heated condition. The degreeof heating eifect of the stove is controlled by the perature of the air within this duct, and a suitable point is selected, which in this in stance happens to be the upper portion of this shell 13, there being placed in the rounded portion 14s a suitable pipe 16, which pipe may be filled with fluid of suitable character, air being used in one of the forms of the invention. The air or other fluid in this-pipe 16 expands and contracts in accordance with the temperature of the air passing through the annular chamber between the stove andthe shell 13. The object of thus controlling the operations of the stove is due to this, that in compartments of the type specified, it is not so necessary to keep the temperature of the. compartment at a certa-ingiven amount as it is to keep the compartment heatedat least a certain number of degrees above the outside temperature. Compartments such as those under discussion are seldom kept at a seventy degreetemperature when the air outside is at zero. If the regulator were set and controlled bythe temperature of the room then the stove would very rapidly burn itself out under conditions of zerotemperature outside of the compartment.
Itis thus desirable to control the operations of the stove in such manner that the stove willnot be unduly drafted even though the outside temperature is extremely low. To control this regulating effect the pipe which extends throiiglioiit;.tlie entire arc of the circle has at one point in its surface an opening which is preferably. provided through the agency of a T connection 17. The lower portion of this T connection commu'nicates with the interior of a duplex expansible and retractable diaphragm 18. The two other arms of this T connection engage the two free extremities of this circular pipe. Thus the entire expanding eflect of the air or other fluid throughout the entire length of pipe finds expression through the lower portion of the T 17 into the exp ansible and retractable diaphragms 18. The lower diaphragm is of course closed but is provided with a lug 19, whichlugthrough the agency of a cooperating lug 20 engages a lever 21. The lugs 19 and 20 are screw threaded andhave a'right. and lefthanded screw thread respectively. A union 22 when turned in opposite directions therefor brings the lugs 19 and20either close together or farther'apart. This union is carried by a spur gear 23 which meshes with another gear 2e, this geaffi being mounted upon a spindle 25, the spindle being suitably rotated and operated by the handle" 26 to thus control the rela-tivefpositions-ot.the lugs 19 and 20. As the air or other fluid expands in the tube 16 it presses the lug 19 downwardly on account of the expansion of the diaphragins 18 and thereby pushes the lever 21 (Fig. 4) in a clockwise direction, this lever being pivoted upon the spindle 27. When the air contracts, the lug 19 is raised as the diaphragms 18 contract thus swing ing the lever 21 in a contra clockwise direction. This lever 21 is directly associated with the chain 9. There is a further lever 28 which is also pivoted on the spindle 27, thislever 2S'moving synchronously with the lever'21. This lever 28: is connected to the link 12. Brackets 29 support the spindle 27 which supports the levers.
The shell 13 has a projection 30 longitudinally thereof which incloses the various projecting parts, thus to maintain acontinuity of the duct. In order to counterbalance the weight of the door 8 and the levers 21 I utilize a leaf spring 31 whose tension is regulated by the wing nut 32, this wing nut cooperatingwith the curved surface 33 to hold this spring 31in any desired position to effect its counter-balancingfunction. The operation of the levers'thencon trols the position of the check'damper 11 and the ash pit' door 8. 1 Of course, any other suitable instrumentalities might be controlled which might control'the degree of combustive efiectof the stove.
In Figs. 6 and 7, I show a stove regulatable similarly to thatshown herein, the various parts being denominated by the same reference characters. The stove 1 again is Placed within a duct consisting of the shell 13 This shell is so arranged that the charging door 34 of the stove projects outwardly of the shell so that the stove may be sup plied with fuel Without having the flame or fire portion communicate with the interior of the said shell 13. The stove and shell are placed'in a small. shed 35 adjacent a garage or other compartment 36. The shell 13 then has a mouth 37 at its lower extremity which projects into the compartment 36, the mouth being covered by a screenBS to gi'iardagainst any contingencies or leaks due to breakage of any of the stove parts.
also taken advantage of to heat the air in the duct 13 I Itwill be seen that in this structure of Figs Gand 7i'the air in the compartment 36 is heated by the stove 1 without having the flame or fire portion of the stove communicate in any way with the interior of this compartment 36. The duct 13 is likewise provided with an inwardly extending mouth 42 to accommodate the ash pit door 8. In this manner it is safe to heat the interior of the compartment 86 through the direct agency of a coal stove without the attending danger of explosions. This stove as shown in Figs. 6 and 7 may then also desirably be regulated the same as the stove shown in Figs. lto 5 inclusive is regulated. Screen 10 protects the opening for the damper 11. From what has been described the nature of my invention will be clear to those skilled in the art. Having however thus described two forms which my invention may take, what I claim as new and desire to secure by Letters Patent is p 1. A device of the character described comprising a fuel burning stove having a grate, a shell surrounding said stove forming a clear channel between said shell and the outer wall of said stove extending substantially throughout the full vertical length of said stove, said channel being substantially fully open at the bottom and at the top to thereby afford an unobstructed passage for an air current upwardly through said channel to thereby heat the air current passing through said channel and cause circulation of the air in the compartment where said device is placed, regulating means for said stove, and thermal means responsive to the temperature of the air in said channel for controlling said regulating means said thermal means comprising a fluid chamber around the top edge of the shell, an expansible diaphragm connected to said chamher and means connecting the diaphragm to the regulating means.
