Specification of Letters Patent.

. Application filed March 22, 1919. Serial No. 284,312.-

To all whom it may concern:

Be it known that I, CARL P. ANDERSON, a subject of the King of Sweden, residing at 25-1; Park street, in the city of Jamestown, New York, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Gas-Heat ers, of which the following, taken in con nection with the accompanying drawings, is a specification.

The invention relates to heating devices and particularly those in which gas is used as fuel; and the improvement consists in providing a simple and convenient portable construction which may be attached to a gas arm or pipe and is so arranged as to substantially consume the hot products of combustion arising from the burning gas; and the invention consists in the construc tion and arrangement of the parts as shown and. described in this specification and the accompanying drawings and pointed out in claims.

In the drawings, Figure 1 is a perspective view of the gas heater attached to an arm having a controlling valve thereon, a portion of the side of the heater being broken away to show the gas burner and construction of the device. Fig. 2 is a lengthwise, vertical, sectional view of the gas heater at line 22 in Fig. 3 showing the preferred arrangement of the same; and Fig. 3 is the crosswise sectional view at line 33 in Fig. 2, showing additional features of the arrangement and construction of the same. Fig. 1 is a perspective view of the metal crown or heating plate against which the flame strikes when said plate is attached in the upper portion of the cylindrical gas heater.

Like characters of reference refer to corresponding parts in the several views.

The numeral 10 designates the cylindrical shaped gas heater whichhas preferably the open end plates 11 and 12 therein. The end plates extend inward a spaced distance from the inner surface of the cylindrical casing 10 to close that portion of the end openings, and are provided at one side with the inward extensions 13 for each end plate to assist in closing the ends of the tubular burner 14, which burner has a series of minute gas openings 15 along its upper side for the as.

h Each of the ends of the burner 14 has a plug 16 into which the screws 17 extend through the inward extensions 13, thereby firmly plugging the tWo ends of the tubular burner 14- and holding said burner in position lengthwise of the lower side of the heater.

On the lower side of the burner 1a a pipe 18 is inserted to which'the tube 19 is attached by threading onto the same, which tube 19' has the mixer openings 20 therein and threads onto the. nipple 21 of the gas arm 22. The gas arm 22 has a valve 23 to control the same. The nipple 2-1 has a small opening 24: for the gas under pressure to force itself through, thereby drawing the oxygen from the atmosphere through the mixer openings 20. Y

The cylinder 10 has preferably a cast metal crown plate 25 which cups over the flame from the gas openings 15 inthe burner 14 and forms a combustive chamber in which the hot products of combustion arising from the gaseous mixture are quite thoroughly consumed. The plate 25 has the lugs 31 thereon at each end with holes therethrough for attachment to the end plates 11 and 12, holding said crown plate 25 a spaced distance from the inner surface of the sheet metal cylinder 10, to thereby provide a heating space 27 between the cylinder 10 and plate 25.

The sheet metal cylinder 10 has a series of openings 26 near the lower edges of the crown 25 opening into the space 27, and at the top a series of openings 28 through which the heated air escapes from said space 27. It is apparent that as the heat invariably rises, it draws the air from the room into the space 27 through the openings 26 at each side and the heated or superheated crown plate 25 quickly heats the same and it escapes through the top series of openings 28. The crown plate 25 is preferably turned toward the inner surface of the sheet metal cylinder 10- at each edge and thereby closes the lower edges 29 on each side. The edges may be made equal or one side may be above the other as shown in Fig. 3. An opening 30 is provided for lighting the gas as it escapes through the burner openings 15. V

It is obvious that the cylindrical shape of the sheet metalcasing 10 permits its quick and easy manufacture. The burner 14 may be made from a piece of gas pipe, though it is preferably cast in the cylindrical form, with closed ends in place of the plugs 15 and a side opening 18 to which the tube 19 may be attached. It is also apparent that the nipple 21 is a common form of gas nipple so that the gas heater can be quickly and economically assembled, at the same time forming a simple portable gas heater which can be attached to any gas fixture and forms an economical means of heating an apartment.

I claim as new:

1. A gas heater comprising a horizontal metal cylinder having openings in the ends thereof, a tubular gas burner lengthwise within the lower portion of said cylinder, a mixer tube and gas nipple connection to said burner for attachment to a gas arm, and a lengthwise cupping crown plate in the upper portion of said cylinder over said tubular gas burner to form a combustion chamber therein.

2. A gas heater comprising a horizontal metal cylinder having partially closed ends, a tubular gas burner lengthwise of the lower port-ion of said cylinder, a crown plate supported in the upper portion and in spaced relation to said cylinder to form a heating chamber therebetween, said cylinder having inlet and outlet openings for the air in said chamber, and a mixer tube and gas nipple connected to said burner for attachment to a gas r -H 3. A gas heater comprising a sheet metal cylinder, end plates for said cylinder partially closing the same, a tubular burner extending lengthwise of the lower portion of said cylinder and attached to Said end plates, a crown plate curving over said burner a spaced distance therefrom and from said cylinder within the same to form a heating chamber between said crown plate and cylinder, a series of openings along the top of said cylinder and a second series along the side of said cylinder just above the lower edge of said crown plate to receive the air through the lower series of openings to heat the same in said chamber and pass it out through the top series of openings, and a mixer tube and gas nipple connected to said burner for attachment to a gas arm to hold said cylinder in a substantially horizontal position. 7 V

In testimony whereof I have aiiixed my signature in the presence of two witnesses.
