EDWARD M. HITOHOOOK, OF PORTLAND, OREGON, ASSIGNOR OF ONE-HALF 'IO H. R. BIERS- DORF, OF MULTNOMAH COUNTY, OREGON.
SUPPLEMENTAL DOWNDRAFT FOR STOVES.
Specification of Letters Patent.
Patented July 28, 1908.
Application filed July 28, 1907. Serial N 0. 385,230.
To all whom it may concern:
Be it known that I, EDWARD M. HITCH- oooK, a citizen of the United States, residin at Portland, in the county of Multnomah an State of Oregon, have invented a new and useful Improvement in Supplemental Downdrafts for Stoves, of which the following is a specification. I
My invention relates to the method of construction and applying a supplemental or additional draft to the ordinary heat stove, cooking stove, furnace, etc., merely by attaching my appliance, as will hereinafter be described and set forth. By adding this supplemental draft, the cold and vitiated air will be taken from the surface of the floor, more complete combustion will take place in the stove, and thereby causing a great saving of fuel. I attain these objects by the device illustrated in the accompanying drawings in which Figure 1 is a front view of the part which fits next to the stove. Fig. 2 is a erspective view of the device showing met 0d of at. taching it to the stove. Fig. 3 is a side view of the device. Fig. 4 is a cross section on-the line A B of Fig. 3. Fig. 5 is a cross section on the line C D of Fig. 3.
Similar numbers refer to similar parts throughout the several views.
1 is the main body of the device which will be made substantially in the shape shown in the accompanying drawings.
2 is a bent neckwhich is curved at the proper angle so the draft will be thrown direct y down on top of the fire in the stove, instead of coming from the side or underneath, as is usually the case at the present time.
Throughout the whole length of 1 and 2 is an opening 3 starting on the bottom end of 1 with the shape as is shown in Fig. 4 and terminating in a circular area at the end of 2 as shown in Fig. 5 It will then be seen that the device is merely a cast or sheet metal shell, through whichthe draft passes when the device is properly fastened to the stove or furnace.
4, 4, are two fiat lugs each containing a hole 5 through which passes bolts 6 which are used to fasten the lower end of the device on the stove.
stove, said body tapering 7 is a flange containing in the u per part a hole 8, through which passes a bo t 9 and by this means the top of the device is fastened to the stove.
To attach my device to any stove or furnace, it is first necessary to make a round opening of sufficient size to admit the neck 2. After inserting this neck, drill three holes in the stove to match the holes 5, 5, and 8 of the device. Into the holes then fasten bolts 6, 6, and 9. It will readily be seen as is best shown in Fig. 2 that these bolts firmly fasten the device against the stove.
The method of operation of the device is as follows: After being fastened on the stove as is hereinbefore described, the air is drawn in from near the surface of the floor through the opening 3 and precipitated downward on top of the fire by means of the bent neck 2. This causes a down draft to take place which tends to make more complete combustion to consume the smoke, save fuel, and take the cold air from near the fioor surface.
I am aware that prior to my invention down draft arrangements have been made and attached to stoves. I, therefore, do not claim such a combination broadly, but
I claim As a new article of manufacture, a supplemental draft attachment for stoves comprising an integral hollow body a side of which is flat so as tofit against the front portion of a toward its upper end which extends lateral y and downwardly to form a neck adapted to project into a stove, the upper portion of the device being formed with a flange arranged in substantially a vertical plane and with its outer face in alinement with the flat side of the body aforesaid, said flange also having its upper portion extended upwardly and formed with an o ening for a fastening, apertured fastening ugs being integrally formed with and projecting from the opposite side edges of the attachment at the flat side of the same.
EDWARD M. HITOHCOOK.
