GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 632,340, dated September 5, 1899.

Application filed October 2, 1896. Serial No. 607,6 80- (No model.)

To all whont it ntay concern.-

Be it known that I, EDWARD .1. DASOHBACH, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical cross-section of my improved gas-stove. Fig. 2 is a rear view, partly broken away; and Fig. 3 is a horizontal section on the line III III of Fig. 1.

My invention relates to that class of openfront gas-stoves wherein a rear chamber for the products of combustion separated from the front burner by an air-space is used, and is designed to improve the economy and increase the heating power of the stove by causing the products to take a circuitous path through a second chamber contained within the rear chamber for the products.

In the drawings, 2 represents the face of the stove, which is upright, open at the front, and has a vertical hollow burner 3, hereinafter described, and 4 is avertical rear chamber separated from the chamber 2 by an intervening air-space 5, which is open at the sides and top. The chamber 4 has at its upper end short pipes or fines 6, opposite to the mouth of which is a hood 7, adapted to collect the products of combustion and to direct them into said flues. In the middle of the chamber 4 is a chamber 4, open at the bottom, being constituted by side walls 8 and an upper damper U.

10 is an outlet-flue leading from the upper part of the middle chamber 4 and adapted to enter a hole made in a plate setin front of and closing an ordinary open fireplace.

The burner 3 is ahollow plate or slab having in its face perforations arranged, preferably, in parallel rows and with intermediate strips of asbestos fiber or the like. Gas is admitted into the burner through a gas-mixer 11 of the ordinary Bunsen type, which enters the burner-chamber back of a vertical partition 12 therein. Said partition does not extend to the top of the burner, but stops short thereof, and thus divides the burner internally into two compartments communirear of the burner face-plate.

. The operation of the apparatus as above described is as follows: Gas is admitted into the burner-chamber and draws with it a supply of air through the mixer. The mixed gas and air ascend in the burner-chamber back of the partition and, passing over the top of the partition, enter the front compartment of the burner, whence the mixture passes through the perforations and, being ignited at the face of the burner, covers the same with a body of flame and heats the asbestos fiber to incandescence. The products of combustion, ascending, are caught by the hood and pass through the pipes 6 to the rear chamber 4. At the beginning of the operation of the stove the damper 9 is'preferably opened, so that the products of combustion pass directly with a clear draft to the outletflue 10 and thence up the chimney; but after the draft of the stove has been well established the damper is closed, and then, as shown by the arrows in Fig. 2, the products of combustion entering the chamber 4 must pass down below the side walls 8 and thence up into and through the chamber 4: before passing out through the flue 10. In this Way the heat of the products of combustion is well extracted and given out to the air of the room by radiation from the front, back, and

sides of the chamber 4: before they escape to the chimney.

At the lower part of the stove, covering the mixer 11 and itspipe, I prefer to set a curved fender 12, having on the inner side a hook it gives a maximum of heat. It is very ornamental and is simple and cheap in construction.

I claim- 1. An open-front gas-stove having an upright burner at the front, a rear upright chamber separated from the front by an airspace and arranged to receive the products of combustion from the burner, andasecond chamber Within the said chamber having side walls and an opening remote from the entrance of the first-named chamber, the second chamberhaving an exit-flue, whereby the products of combustion are caused to take a circuitous path through the firstnamed rear chamber.

2. An open-front gas-stove havingaburner operation of the damper the products of com-- bustion can be caused to assume a direct or circuitous path to the exit-flue, as desired.

In testimony whereof I have hereunto set my hand.
