GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 408,980, dated August 13, 1889. Application filed January 28, 1889- Serial No. 297,855. (No model.)

To all whom it may concern.-

Be it known that we, JONATHAN J OHN- SON and EDMUND I-I. PAOKER, citizens of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Gas-Heaters; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the sam e, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in that class of heaters or radiators in which gas is used for fuel, the 'object being to so construct the radiators that the number of parts shall be few and readily connected, and by using two sets or rows of radiator-pipes, one of which receives the burners and has an upward current through them, and then returning the products of combustion downward through the other set of radiator-pipes, ex tract all the available heat produced bythe combustion of fuel.

A further object is to so construct the gasburner that the gas shall be thoroughly mixed with air before burning.

To effect these objects we construct a base with two chambers, one of which receives the gas pipe and burners, and into which chamber is also secured a chamber, which forms a return for the products of combustion passing up through the first row of tubes to a corresponding row placed parallel with the first, down through which they pass to the other chamber in the base, and from which chamber they are carried by a suitable flue to a chimney or other proper place of exit. The burners are placed in line beneath the vertical tube and are each provided with a branch pipe, through which the atmospheric air mixed with the gas before burning passes.

In the accompanying drawings, which illustrate this invention, Figure 1 is a perspective View of the heater complete. Fig. 2 is a vertical section through the same on the line 0300 of Fig. 1, showing the arrangement of the gassupply pipes and burner, radiating-pipes, and

the chambers which they connect. Fig. 3 is a perspective View of the gas-pipe and burners removed from the heater. Fig. 4 is aview, partly in section, of a pipe with one of the burners upon an enlarged scale to more fully illustrate its construction; and Fig. 5 shows a modification of the deflector.

In these several figures, A represents the chambered base, preferably of cast-iron, and provided with suitable legs A to support it a proper distance from the floor. One chamber of this base, as B, is open at the bottom and is intended for the reception of the supply-pipe and burners. The other chamber B is closed at the bottom and provided with an exit-pipe a, through which the waste products of combustion escape. Secured in the top of this base A and opening into the chambers B and B are two rows of vertical tubes or radiating-pipes C O. The tops of these rows of pipes enter into and are connected by a chamber D, which may also be of cast metal and provided with-a removable cover D, by the removal of which access is gained to the upper ends of the radiating-pipes. The gas-supply pipe E, which supplies the burners, is carried in suitable bearings at each end of the base A, and extends below the chamber B from one end of the base to the other. Screwed into the upper side of this pipe E is a series of burners bone for each radiating pipe or tube in the row above it. A short pipe I) is screwed into the pipe I) diagonally or is formed integral therewith, and admits air to the gas that flows through the burners, the size of the opening in the pipes Z) and I) being adjusted to allow the mixture to issue at the top in such a condition as to give out the greatest heat of which the gas is capable. The tip 0 of the burner forms an enlarged cone-shaped disk above, which is retained in the deflector e by means of the standard e, connecting said deflector with the disk 0.

From this construction it will be seen that the mixture of atmospheric air and gas issuing from the top of the burner strikes the under side of the deflector and is thrown outward and downward. periphery of the deflector, from which the flame rises in a tubular form, nearly filling The "as ignites at the IOO the lower end of the radiating-pipes above them. From this point the heated gases pass upward, as shown by the arrows in Fig. 2, into the chamber D, by which they are returned to the opposite row of radiating-pipes and conducted downward to the chamber 13, thus giving an extended course for the passage of the pro 'lucts of combustion throughout the pipes and chamber before they can escape to the flue.

The gas-supply pipe may, if desired, be carried in bearings, which will allow of its partial rotation by means of a handle (I attached thereto, thus bringing the burners into a more convenient position for lighting. This construction, however, and arrangement of the rotatable supply-pipe form no part of this invention, it being fully shown and described in the application of Jonathan Johnson for a patent for improvements in heating apparatus, filed October (5, 1888, Serial No. 28?,l08.

The modification shown in Fig. 5 consists in a plate f, secured to the base A and proj ecting inward over the burner to supply the place of the deflector when said deflector is not used.

-1Iaving thus described our invention, we

claim as new and desire to secure by Letters Patent the following:

1. As an improvement in gas-heaters,1he

combination of the radiating-pipes, the rotatable pipe E, supported beneath said radiating-pipes, the burners carried by said rotatable pipe, and the deflectors fixed over the orifices of the burners, substantially as and for the purpose set forth.

2. As an improvement in gas-heaters, the radiating-pipes, in combination with the rotatable pipe E, supported beneath the mouths of the said radiating-pipes, the burners carried by said rotatable pipe, and the supplypipe I), for carrying air to the base of the burne substantially as and for the purpose set forth.

3. As an improvement in a gas-heater, the radiating-pipes, in combination with the rotatable pipe E, supported beneath the mouths of the said radiatingnpes, the burners carried by the rotatable pipe, the deflectors fixed over the orifices of the burners, and the airsupply pipe leading to the base of the burner, for the purpose specified.

In testimony whereof we affix our signa tures in presence of two witnesses.
