RADIATOR Filed July 20, 1951 Patented May 2, 1933 stares insane EUGENE V. DAILY, ()F LOS ANGELES, CALIFORNIA, ASSIGNOB T0 JAMES B. GLOW & SONS, OF CHICAGO, ILLENOIS, A CORPORATION OF ILLINGIS RADIATOR Application filed July 20, 1931.

The invention relates to gas fired heating devices and has reference more particularly to improvements in the specially constructed or vent section of gas fired steam radiators.

Radiators of this class usually comprise a series of sections having a combustion chamber disposed within the lower part thereof and the customary water and steam chambers located above the combustion chamber. lVithin this latter chamber there is positioned a fuel burner and in order'to carry off the products of combustion from the burner the radiator is provided with a specially constructed section that is in connection with a vent outlet. Products of combustion arising throughout the length of the lower part of the radiator flow into the specially constructed section and are discharged through the vent outlet. In the operation of such radiators it is not uncommon for a back draft of air to rush down the vent with the result that unless some provision for counteracting this effect is made, the danger arises of the gas flame at the burner being extinguished and the gaseous fuel passing from the burner without burning. Again it is not unusual for a strong up-draft to exist in the vent under certain conditions, creating a strong updraft in the vent section of the radiator and unless some provision is made to compensate such strong up-draft there is a tendency for the gas flame to be lifted off the burner with the result that the gas flame might be entirely extinguished and unburned gas would then be passing from the burner.

For relieving the effect of the down-drafts and strong up-drafts, radiators of this class have heretofore been equipped vith an eX- ternal and detachable draft diverter or regulator placed in the vent pipe connecting the vent section, which section is located centrally of the length of the radiator, to the chimney or outside atmosphere.

The present invention is concerned with improvements to the above described method of providing a device for preventing clowndrafts or excessive updrafts from interfering with the normal burning of the gas by incorporating it in the vent section and to Serial No. 551,899.

locate the relief opening that is an essential part of a draft diverter in that portion of the vent section that would normally be facing the wall and therefore out of view A still further object is to provide the flue chamber of a vent section with a wall of special configuration, which wi l be so posi tioncd in relation to the vent and relief opening as to direct the out-going products of combustion toward the vent and the down-drafts toward the relief opening.

\Vith these and various other objects in view, the invention may consist of certain novel features of construction and operation as will be more fully described and particu larly pointed out in the specification, drawing and claims appended hereto.

In the drawing which illustrates an em bodiment of the device, and wherein like reference characters are used to designate like parts Figure 1 is an elevational view, parts being shown in section, of a radiator constructed in accordance with the present invention;

Figure 2 is a fragmentary vertical sectional view taken substantially through the center of the specially constructed vent section, and

Figure 8 is a fragmentary vertical sec tional view showing a modified form of construction of the vent section.

Referring to the drawing there is shown in Figure 1 a radiator comprising a plurality of sections 2, 4, 6, 8 and 10, each of the sections comprising, as shown in Figure 2, a steam chamber 12 located within the upper portion of the section and a combustion chamber 14 formed within the lower part thereof. The sections are joined together by means of nipples l6 projecting laterally from the sides of the steam chamber and water chamber 20 and by means of laterally extending side walls 18 projecting from the combustion chamber 14, the water chamber 20 and the steam chamber 12. Each section is also provided with a water chamber 20 located intermediate the combustion chamber 14 and the flue passage 19 and defined by the top and bottom walls 22 and 24, respectively. The water chamber of each section has communication with the steam chamber 12 formed in that section by means of the passage 26 and the water chamber of each section is joined as shown in Figure 1 by nipples 16.

Thus when a radiator is assembled the steam chambers of the adjacent sections are in communication with one another by means of nipples 16 and the water chambers are likewise in communication by means of other nipples 16 located therein. The combustion spaces in the various sections are aligned with one another and are closed off at the outside surface of each end section to form a single large chamber extending throughout the length of the radiator in the bottom portion of the same. During the use of the radiator an elongated burner 30 is inserted lengthwise of the combustion chamber 14 of the radiator and is supplied with a suitable quantity and quality of fuel for generating steam from the water with in the chamber 20. To insure proper combustion it is necessary to supply secondary air to the burner and accordingly this air is supplied through opening 32 located in each section.

Products of combustion forming in the combustion chamber 14 flow' upwardly between the various sections of the water chamber 20 and then lengthwise of the radiator through the flue passage 19 into the central vent section 6, which is specially constructed, as shown in Figure 2. The vent section 6 is preferably of the same appropriate configuration as the adjacent sections and contains a second flue passage 34, which does not exist in adjacent sections, formed immediately above the flue passage 19 which is common to all adjacent sections and receives all the flue gasses from flue passage 19. A vent opening 36 in the rear wall of flue passage 34 provides for a vent pipe connection 38 to. a chimney or outside air. Also formed in the rear wall of flue passage 34 below the vent opening 36 is an atmospheric or relief opening 40. In order to more effectively direct the upward moving products of combustion in flue passage 34 toward the vent opening 36 the lower portion of the rear wall 42 may be curved as in Figure 2, but the directing action is also accomplished when 42 is vertical as in Figure 3.

A feature of the present invention is the particular configuration given to the top and front walls, which in connection with the vertically extending side walls 44 and 46 of flue passage 34 and the vent opening 36 and relief opening 40 serve to complete an effective draft diverter, which effectively protects the combustion of fuel at the burner 30 against disturbance from either a down-draft or an excessive up-draft in the vent pipe connection 38. As shown in Figures 2 and 3 the top wall 48 extends from the vent opening 36 and is curved downwardly merging with an arcuate portion 50 of the front wall of flue passage 34 or with what may be described as a portion of more determined curvature. The sloping front wall 52 extends from a point on side walls 18 adjacent the water chamber and unites with the arcuate portion 50, forming a cusp 54, which is positioned directly opposite the atmospheric or relief opening 40.

In operation of the radiator the products of combustion formed by fuel burning at burner 30 rise and flow upwardly between the adjacent sections of the water chamber 20 and then longitudinally through flue passage 19 of the radiator into the central vent section 6. Under conditions of normal rip-draft in vent pipe 38 and within section 6 they rise into flue passage 34 and are guided in their movement by means of the various walls referred to until they finally pass from the vent section through the vent opening 36. To direct the rising products of combustion toward the vent opening 36 the baffle 42 is provided, which, in connection with sloping front wall 52, and side walls 44 and 46 form a restricted passage through which the products of combustion must flow before entering the upper portion of the flue chamber 34.

When a back draft flows down the vent pipe 38 and into the vent section the draft diverter which constitutes this invention directs the downwardly flowing air by means of the sloping top wall 48 toward the areuate portion 50, which is so positioned in relation to the vent opening 36 and atmospheric opening 40 that the drafts will be directed outside the vent section through the atmospheric or relief opening 40, thus preventing the down-draft from passing into the lower portion of flue passage 34. At the same time the flue gases are accelerated in their upward passage in that portion of the flue passage 34 located below the upper end of baifle 42 and the cusp 54 by reason of the siphoning action of the down-draft moving at approximately right angles to that portion of the flue passage located between these two points, which causes the upward moving flue gases to join the downdraft and pass from the vent section with the down-draft through the relief opening 40. In this manner back drafts are pre vented from effecting the combustion of the fuel at the burner 30.

hen there is an abnormally strong updraft in the vent pipe 38 the atmospheric or relief opening 40 acts as a draft check by permitting the entrance of air from the room to the upper portion of the flue passage 34, thereby maintaining a normal draft in the lower portion of flue passage 34:, which prevents the strong up-draft from disturbing the combustion of fuel at the burner 30.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
