I CHARLES C. JESSEN, F OAKLAND, CALIFORNIA.

GAS-RADIATOR.

Application filed February 3, 1917.

To all whom it may concern:

Be it known that 1, CHARLES C. Jnssnn, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Gas-Radiators, of which the following is a specification.

My invention relates to the class of I radiators in which gas is the heating medium, in practice ordinary illuminating gas and air supplied to and ignited at a Bunsen burner.

The objects of my invention briefly stated, are efficiency and economy in operation, as the result of proper direction and distribution of the heated products of combustion, cheapness in manufacture due to a simple and practical construction, and safety in manipulation and use, owing to the provision of effective safeguards.

To this end my invention consists in the novel gas-radiator which I shall now fully describe, by reference to the accompanying drawings, in which Figure 1 is a front elevation of my gasradiator.

Fig. 2 is an end view of the same.

Fig. 8 is a sectional view on the line 3-3 of Fig. 5.

Fig. i 1s a sectional view on the line 4-4 of Fig. 5.

Fig. 5 is a sectional view on the line 5-5 of Fig. 1, the bottom plate being broken away.

Fig. 6 is a plan, enlarged, of the burner showing its encircling damper.

Fig. 7 is a side elevation, partly in section, of the same.

1 is the radiator tallic shell or casing,

body consisting of a methe walls of which may be suitably fluted to increase the radiating surface and for ornamental effect. The top of the shell is closed either integrally or by a cover such as 2. To the base of the shell is fitted a bottom plate 3 with legs 4-. The bottom plate 3 carries a burner 5 the controllable connections of which are of the usual Bunsen type, comprising, the gas pipe 6 with its cock 7 and its air inlet 8. A space 9 for entrained air is left in the bottom plate around the burner, and this air space is controlled by a damper comprising a fixed apertured ring 10 and an adjustable apertured ring 11, as seen in Figs. 6 and 7 turnable Specification of LettersPatent.

Patented May 8, 1917. Serial No. 146,504.

upon the fixed ring to carry its apertures into more or less complete registration with the apertures of the fixed ring as may be required and as will be presently more fully described.

Over the burner 5 and the encircling damper-controlled air-space 9 is fitted a me tallic pipe 12, extending upwardly within the shell 1, its top being open and turned at an angle as shown at 13. In the lower portion of this pipe is an opening 12 to afford access to the burner, to light it.

Within the shell 1 is the flue-pipe 14:. The lower end of the flue-pipe opens into the shell near the bottom thereof, and its open upper end lies normally in communication with the exit 15 in the upper portion of the shell, which exit communicates, as shown in Fig. 2, by a pipe 14 with the flue-wall 15. The flue-pipe is hung within the casing upon a pivot 16 so disposed, as, for example, to one side of the vertical axis of the flue-pipe, that the latter when in equilibrium hangs with its open upper end in registry with the exit 15 of the shell, as shown by the full lines in Fig. 3.

17 is a swinging door in the casing, in position to afiord convenient access to the burner 5, to light it through the opening 12 in the radiating pipe 12. The door 11? is connected by means of a crank arm 17 on its inner side, and a link 18 with a crank arm 19 on the flue-pipe 141:, the arrangement of the connection being such that when the door is shut, the flue-pipe hangs with its open upper end in registry with the shell exit 15; but when the door is open, the fluepipe is turned on its pivot, so that its open upper end lies out of communication with said exit, as shown by the dotted lines in Fig. 8, which exit is thus exposed to the shell interior.

The use and operation of the device are as follows :When the door is opened and the gas turned on, the operator reaches in with a lighted match and attempts to light the inflammable mixture at the burner. If unsuccessful in this, his tendency is to reach for another match while the door is still open. As before mentioned, while the door is open, the pivoted flue-pipe 1a is swung to expose the shell-exit 15, and, therefore, the unlighted gaseous mixture instead of filling and being confined in the shell while he finds another match, a condition likely to create an explosion upon his renewed attempt at lighting the burner, escapes freely from the shell through the exposed exit 15. He can, therefore, safely light the burner with his second match. When this is done, the door will be automatically closed by the gravity of the flue-pipe 14: returning to its normal position, in which its open upper end registers with the shell-exit 15. Thus, the radiator is lighted and closed up, the operation being free from the consequences of oversight or neglect. The heated products of combustion now pass up through the radiating pipe 12, and are delivered into the upper portion of the shell 1. Spreading therein in all directions, and necessarily downwardly to reach the open lower end of the flue-pipe 14, they are thus fully distributed throughout the shell and equally heat it over its entire surface. Thence, through the flue-pipe 14 they pass off.

The radiating pipe 12 has a double function. It not only conducts the heated products of combustion to the upper portion of the radiator shell, but it serves also as kind of super-heater, promoting combustion, augmenting heat radiation and destroying obnoxious odor. The supplementary or entrained air admitted around the burner and flame, through the air space 9, and its proper control at this point by the damper is advantageous, in that it affords opportunity to regulate the draft in accordance with the gas pressure, and without deleteriously affecting the circulation, as would be the case if the flue-pipe were dampered. This is especially the case in connection with the upright radiating pipe 12, which tends to create an up-rush of gas, flame and products of combustion. But by observing these effects in any given instance, and adjusting the damper ring 11 accordingly, mentary or entrained air can be admitted in the required volume to regulate the draft, and by causing the heated products of combustion to proceed more leisurely, through the radiator, make them yield their maximum heat before passing off.

It will thus be seen that a simple, relatively cheap, and highly efiicient radiator is provided, the proper use of which is readily learned and is not open to mistake or neglect.

I claim 1. A gas-radiator comprising a radiating shell having an exit in its upper portion; a gas-burner fitted to the lower portion of the shell; a flue-pipe within the shell, open at its lower end to the lower portion of the shell interior and at its upper end adapted to register with the shell exit; a pivot connection suspending said flue-pipe within the shell; and means for swinging said flue pipe Copies of this patent may be obtained for five cents each, by addressing the the suppleinto and out of registration with the shell exit.

2.
