UNITED STATES WILLIAM G. HUTCI-IISON, OF PORTSMOUTH, OHIO.
AIR CIRCULATOR FOR STOVES.
Application filed November 28, 1927. Serial N... 236,215.
This invention relates to heating'stovcs and more particularly to a circulator attachment for circulating stoves of the type known as parlor stoves.
A primary object of the invention is to provide a circulator which, when in use, will cause the stove in connection with which it is used to throw off a maximum amount of heat wit-h a minimum consumption of fuel, thereby greatly increasing the heating effect of the stove without increasing the fuel consumption.
Another object is to provide a device of this character which may be applied to any stove already in use and which may be put in place or removed in a few minutes by any unskilled person.
Another object of the invention is to provide an attachment for heating stoves wherein air surrounding the stove may be drawn in, heated, and discharged from the upper part of the stove in addition to providing the usual radiation incident to a hot stove.
Still another object is to provide an attachment of this character wherein the effective radiation area of the stove is enlarged and the heated air discharged therefrom with considerable force.
In carrying out these objects, the invention is susceptible of a widerange of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings for illustrative purposes a preferred and practical form, in which;
Figure 1 represents a front elevation partly in section of a stove with this improved attachment shown applied,
Fig. 2 is a detail perspective view of one of the elements constituting a part of the invention,
Fig. 3 is a horizontal section taken on the line 33 of Fig. 1, and
Fig. 4 is a top plan view of the attachment detached.
In the embodiment illustrated, a heating stove 1 is shown including a base 2 sup ported by legs 3. The base 2 has air inlet openings 1 arranged at opposite sides thereof as is usual with stoves of this character. The body of the stove is composed of an outer shell or casing 5 within which is arranged and spaced therefrom an inner shell or drum 6 which extends well down over the fire pot 7 The upper end of the inner shell or drum 6 has a truncated cone-shaped top by an annular stove lid. seat 9, all of these parts being of the usual construction in stoves of this character. Above the top of the casing 6 and supported by the outer shell 5 is a perforated shell or grate-like top 1 the apertures of which provide for the free passage of the heated air therethrough and its outflow into the surrounding atmosphere.
The circulator 1O constituting this invention comprises a body portion 11 preferably constructed of sheet metal, although it may be cast if found desirable to do so. This body 11 has an annular flange 12 at its upper end designed to rest on the flange 9 of the casing 6 and to fit snugly in airtight relation thereto. This body 11 depends into the casing G and its lower end is preferably made inverted cone-shaped as shown at 13 with its apex 14L arranged directly above the fire box and against which the flame or heat from the fire is designed to impinge and be deflected out into the casing 6, from which it is radiated into tl e space between the inner and outer shells. Carried by the body member 11 are a plurality of tubular air conducting arms 15, any desired number of which may be employed, two being here shown and which are preferably made inverted Jshape in form with the short member 16 thereof arranged within the body 11 against the wall and secured to said body in any suitable manner, metal bands 17 being here shown for this purpose.
The long member 18 of each circulating tube 15 depends into the space between the inner and outer casings of the stove, as is shown clearly in Fig. 1, and the free end thereof is flared, being made bell-shaped in form as shown at 19. These bell-shaped mouths 19 of the tubular members 15 may be be located at any desired point within the stove casing, and are designed to collect the air entering through the inlets 4 and direct it into the body member 11 of the circulator. The air discharged into the main body of the circulator follows the direction of the arrows and is subjected to the heat from the side walls of said body and passes out through the apertured top member 1 into the surrounding atmosphere. These 8 with a central opening therein surrounded tubes may be of any desired size, length or shape but are preferably constructed as shown in the drawing.
\Vhen the circulator 10 has been placed in the stove, as shown in Fig. 1, and the walls thereof become thoroughly heated, it at once causes an inward draft of outside air through the tubes 15 into the main body 11, and there becoming highly heated is discharged with considerable force out through the top 1 into the room.
This circulator 10 because of its shape, defleets heat it does not absorb against the sides of the stove casing and thereby highly heats said casing which deflects the heat out into the room and prevents its passage out through the flue without first having exhausted its heating power.
It is, of course. understood that the body 11 may be varied in length to adapt it for use in different types and sizes of stoves, it being designed to extend down into the stove far enough to be in the path of the flame and yet not interfere with firing of the stove.
It is also understood that this attachment may be applied to either an old or a new stove, provided such stove has a space to receive the arms 18 of the circulating tubes and a central opening with a stove lid flange to support the body portion thereof. This attachment may be quickly taken out and applied, as will be easily seen.
Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, pro portion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.
I claim 1. The combination with a stove having inner and outer spaced walls surrounding a fire box with an opening in its upper end; of a heated air circulator comprising a hollow body member insertible through said opening and having means for supporting it therein, and a tubular arm associated with said body and having a free open end located in the space between the walls of the stove, said stove having air inlets between said walls.
2. The combination with a stove having inner and outer spaced walls surrounding a lire box with an opening in its upper end; of a heated air circulator comprising. a hollow body member insertible through said opening and having means for supporting it therein, and tubular arms associated with said body and having free open ends located in the space between the walls of the stove, said stove having air inlets between said walls.
3. The combination with a stove having inner and outer spaced walls, a fire box located within the inner wall, said stove having an opening in its upper end and air inlet openings in the outer wall to let air into the space between said walls, a heated air circulator comprising a hollow body member insertible through said top opening and having a laterally extending flange at its upper open end for supporting the body on the stove, and a plurality of inverted J-shaped tubular arms associated with said body having their short members inserted therein and extending to a point near the bottom thereof and the long arms insertible in the space between the walls of the stove.
