. -J. w. EBERT SMOKE AND GAS COLLECTOR FOR FURNACE DOORS Filed Feb. 4, 1925 Patented Dec. 29, 1925.
UNITED STATES JOHN WILLIAM EBERT, FREDERICK, MARYLAND.
SMOKE AND GAS COLLECTOR, FOR FURNACE DOORS.
Application filed February 4, 1925. Serial No. 6,748.
To aZZ whom it may concern:
Be it known that I, JOHNv TVILLIAM Ennnr, citizen of the United States, residing at Frederick, in the county of Frederick and State of Maryland, have invented a new and useful Smoke and Gas Collector for Furnace Doors, of which the following is a specification.
The present invention is an attachment for furnaces, and having'for its object the elimination of gases, smoke, fumes and the like, which emanate therefrom when the stoking door of the furnace is opened.
It is well known that proposals of this general nature have been previously made, but such devices are so cumbersome, complicated, expensive and constructed as to be of no practical use.
Among the objects of the invention, therefore, it is the purpose of the present invention to provide an extremely simple and inexpensive device of the above stated character which can be installed on furnaces by a layman, and which is practically adapted for general use on all types of furnaces, namely, hot-air furnaces, hot-water furnaces, steam furnaces and the like.
' The invention further resides in the sundry details of construction, combination and arrangement of parts which will appear from this specification and be particularly pointed out in the appended claim.
In this specification and the annexed drawings, the invention is disclosed in the form in which it is considered to be the best, but the invention is not limited to such form because it is capable of being embodied in other forms; and it is to be understood that in and by the claim following the description therein it is intended to cover. the invention in whatever form it may embody within the scope thereof.
In the drawings which illustrate the preferred embodiment of the invention as at present devised;
Figure l is a front elevation of a furnace equipped with the invention, and
Figure 2 is a side elevation of a furnace equipped with the invention, as shown in Fig. 1, with parts of the hood structure broken away to illustrate its construction.
With particular reference to the drawings in which like characters denote similar and like parts referred to in the specification, A represents the furnace, here shown as of the hot water or steam type of boiler furnace,
of the stoking door B to be hinged on a frame F which is suitably secured to the wall of the furnace and has a projection or flange 7 extending therefrom.
The present invention resides in a hood 1 of any general type or design adapted to be positioned immediately above the stoking door and adapted to have one edge thereof, or other suitable portion thereof, engage and rest upon a portion of the furnace, the upper end of the hood being in communication with a suitable conduit or other means for conveying the gases and the like from the hood by the means of the natural draft therethrough. In the present showing, the connection between the hood and the conduit 2 is such as permits the hood to be shifted or moved from its normal position shown in the drawings to enable access to the soot doors E for the purpose of cleaning.
The specific construction now contemplated and used consists of the hood 1, made of suitable sheet metal material opened at its bottom or underside and having a width approximately the same or slightly greater than the width of the opening at the stoker door B, the side walls of the hood being tapered from this point upwardly so as to eliminate corners or pockets in which'dust, gases or the like may accumulate while pass, ing upwardly in the hood, thus directing the gases and dust upwardly to a suitable opening 3 in the top wall of the hood. This opening 8 is preferably, but not necessarily, provided with an inturned flange a. The conduit 2 is provided with a down turned end y, which may be accomplished by using an ordinary stove pi e elbow, the lower end of this down'turned end 3 removably and slidably extending into the opening 3 of the hood and having a fairly snug fit therewith. The other end of the conduit 23 is directed to a suitable exit into which the gases are discharged and as shown in the drawings preferably tapped into the fine pipe G of the furnace. Of course it is well understood that the end 2 of the conduit 2 may be tapped into the chimney I, or to any other discharge exit. The conduit 2 is, however, provided with a damper 4 for the purpose of controlling the draft therethrough so that the furnace will not be robbed of its natural drafts, except to a partial extent when the damper 4 is opened, and the damper is only to be opened when stoking door B is opened.
t is also manifest that the present invention may be used as a check draft device when installed on furances not otherwise equipped with the same.
In the form of; the invention now illustrated the lower edge of the back wall of the hood is slightly extended outwardly and laterally or otherwise formed with suitable projection indicated at 5, this projection 5 being adapted to rest upon the frame flange f of the stoker door B or any other suitable projection onthe furnace above the door B. It will thus be seen that with the present construction the hood 1 in its normal position is held in place by reason of its connection with the end. 7 of the conduit 2 and by reason of the lower edge of the hood at 5 resting upon a permanent portion of the furnace immediately above the stoking door.
It is common knowledge that when the stoking door B is open for any purpose, and particularly when refueling the fire, smoke, gas and other fumes emanate through the door, which fill the furnace room and in domestic houses frequently find their way to the living rooms, thus tarnishing silver, killing plant life and having other detrimental effects, and when wood or soft coal is used flame flares spring through the door. This gas, smoke, fumes or flares are drawn by the invention into the hood and conveyed by reason of the draft therethrough up into the chimney, when of course the damper is properly set. lVhen the invention is not in use the damper 4 1S closed in order that the draft through the furnace flue G is not di-i verted from the furnace.
lVhen it is desired to clean the heating coils, access to the door E is readily ermitted by simplv lifting the hood 1 so that the portion 5 thereof is disengaged from the furnace, and then draw the hood downwardly to disengage the end 7 of the conduit from the opening 3 ofthe hood. Obviously the hood may be replaced with the same facility.
From the foregoing it will be observed that a very simple, economical, and practical device has been provided for use in connection with furnaces of all types for the purpose of eliminating gas, dust and the like which emanate from the stoking door when the latter is open, and that the use of the present invention will encourage a more universal use of soft coal for domestic purposes.
Having thus described the invention what I claim as new is:
The combination with a furnace having. a stoker door and an abutment thereon above said door, of a hood positioned in front of the furnace and above said door and having the lower rear edge thereof provided with an outwardly extending projection engaging and resting upon said abutment, said hood having an opening in the upper portion thereof, a flue being detachably inserted into said opening whereby the hood may be readily detached by lifting it from engagement with the abutment, moving the hood relative to the fine to withdraw the latter from the opening.
In testimony whereof I have hereunto set my hand.
JOHN \VILLIAM EBERT.
