. @As RADIATOR.

Application filed January 14, 1926. Serial No, 81,238.

My invention relates to radiators, andfithas special reference to radiators in which.

heat is generated .by means of a gaseous fuel, and the heated gases are caused to circulate through the radiators forheating portion of the element broken away; and

thelsurrounding air by direct radiation.

In such radiators of this class as are provided with spaced radiating loops therein, 1t

has hitherto notbeen found possible to ar-` range the heating/elements thereof so that the ilamesfrom theburning gases and their n polychromatie effects Aupony and about the said elements are visible to observers in a room, such as they fire `and glow exhibits of the common open fireplace. y l

The principal object of my invention is to provide a radiator of thisclass Withheating elements and to arrange a transparent plate or facing'in front of the elements so that, a person in the vicinity of the radia.

tor may watchy the pleasing elfects. of the burning gases in combination with the incandescent heating elements,n while at the Sametime he is enjoying the warmth from the radiator.

Another object of the inventionis" to arrange a transparent plate in front of Ithe heating elements in a radiator so as to pre-V ventthe clothing of a person in close prox-` imity to the radiator from being drawny into the flame and from'being seton'flre' thereby. K e

A still further object `is yto `construct a radiator of this class withV a transparent plate of glass, or the like, preferablyV of a heat-resisting kind, for the heatingelements in the radiator in suchamanner that 'the plate can be easily attached to or detached from the radiator, and so that the liability to the breaking ofthe plate is minimized. -V

Other objects and advantages of my invention will be understood from the follow-f which Figure 1 is a yrear elevation of a. live loop radiator constructed in accordance to my invention;

Fig. 2 is an endelevation thereof;

Fig. 3 is a vertical section taken along the line 3-3 of Fig. 2 and looking toward the transparent plate, the heating elements being removed.

Fig. 4 is an enlarged central sectional view through one of the radiating loops;

"llllllllllllllllllwb,

Fig. 5 is a similar sectional view ofthe middle loop atv its top; l

Fig. 6 is an enlarged frontelevation of one of the heating elements;

Fig. 7 is aside elevation of Fig. 6 with a k tion with the other loops except at the'top of the unit assembled radiator. The separate loops are joined together by rods at the top and the bottom, as shown at 1 and 2.

At' the extreme top ythe individual loop sections open into each other and form a chamber 3, which constitutesl a superheater, and also open into each other below the superheater rand form a combustion chamber 4, which is separated from the superheater byV an angular wall 5. Otherwise, the

individual 'loop sections are separateor insulated from eachother and are preferably sealed at their joints by cement in the usual manner.

Near. the top of each loop section is a combustion passageway 6. These open toward each 'other so as tol form a continuous passageway through the radiator, and at the ends of which the passageway is closed by walls 7 and 8 in the outer loop sections. To

each of these walls is removably secured at l its lower end, the upper reduced part of av fire box 9 at respective end walls 10 and 11 of the box'. .This reduced part vfits between a baiile wall 12, which is formed in all the `loop sections, and another wall 13, which is formed opposite to the baille wall 12 and is integral with the angular wall 5 in four of of the loop sections, as is shown in Fig. 4l,

but'is in the middle loop section 14 substi 100 -tuted by a wall 15,'cor`responding in height with the height of the baffle wall 12, as is shown in Fig. 5.

The lire box is open at its top, and also at its bottom for the inlet of air and is in its hold a heatradiating element `18 oflava 110 loop section.

composition or other equivalent inaterial having incandescent properties. At the bottoni of the fire box the back thereof has its edge turned inward, Fig. 4, so as to forni a longitudinal flange 19 adapted to rece-ive thereon a protecting element 2O which inay be ceinented to the back, and which inay bev of a lire brick formation or solne other heatresisting body. The fire box is at its bottoni front also provided with an inward and upward lturned edge, so that thereby a longitudinal groove 21 is forined which is adapted to receive therein the lower edge of a transparent plate 22, which preferablyy is of a heat-resisting glass, such as that known by the tradenanie of pyrex, in order not to be liable to breakage from the heat of the burner. Under the reduced portion atv its top, the fire box is longitudinally provided with a downward flange 23, which with the front of the lire box forms an upper groove 2et'adaptedl to 1' ceive therein the upper edge of' the glass plate. Both grooves 21 and 24 are of awi'dth sufficient to allow a clearance play of the plate therein, and the height of the plate is preferably such that it allows the plate to be lifted up into the upper groove 24 and to, clearthe upturned edge at the lower groove 21 when it is desired either to insert the plate into or to reniove it from the fire box, as is shown in Figs. 4 and 5. The front of the fire box is thus open, but normally closed by the plate, so that the Haines froin the burner tips and their polychromatic effects upon the radiating elenients 1S' niay be visible through the glass plate. Sufficient space is provided between the bottoni of the fire box and the series of loop sections for allowing the fire box to slide under the lower edges of the walls 12, 13 vand 15 into place for connecting it and the burner tube with the radiator R' or for disconnecting theni therefrom.

As has already been mentioned, the wall 15 of the middle loop unit extends upward about to the height of the bai'iie wall 1'2. This is for the purpose of providing a direct opening to the flue 25' at the rear of the A damper 26 adapted to close this opening is mounted' on a rod, which is supported by the walls of the loop section 14 and extends tothe outside of the radiator, inay be operated by a bundle 27 at the end Vofthe rod for causing direct suction through thefflueY at the initial operation of the radiator, or for preventing such suction when the radiator is hot and functioning properly.

1n a foriner construction of a gas radiator, for which I was granted Letters Patents, No. 1,470,293, in the United States on October 9th, 1923, the gas burner was arranged in the upper part of the radiator. For the purpose of the present invention the gas burner is placed in the lower part of the radiator, as has already been described and as is clearly shown in Figs. 3 and Ll. 'Vith the exception of the construction and the arrangement of the fire box with the glass plate and the fi'rebriclr therein, the burner tube, the heating elements thereon and i'ni'nor details in connection with the radiator, the construction disclosed in the present invention is similar to the one shown in the aforementioned patent, and the operation of both radators is substantially identical. The operation of the radiator disclosed in the present invention will therefore be understood from the description in the Letters' Patent referred to, so that a repeated description appears superfluous.`

Having thus described my invention, I claiin as new and desire to secure by Letters Patent of the Uni-tedv Stat-es the. following In. a gas radiator comprising separable gas-circulating loops secured together so as to forni longitudinally through the radiator a combustion passageway closed; by end walls, said loops opening into each other at the top thereby defining a superheater charinber, a lire box provided at its topwith an open reduced portion fitting in this said longitudinal passageway and withl its closed ends` detachably secured to said. end walls, the fire boxV also havingv anV open front wall and. an open bottoni; the front wal-l having at the bottoni an inward and' upward turned edge forming a longitudinal groove; a downward flange fornied at the top of the fire box and under the reduced portion so that, thereby a longitudinal groove is formed at the front Iof the fire' box and above the firstinentioned groove; a gas burner mounted longitudinally in, the tire box and' near the bottoni thereof; and a. transparent plate slidably and removably niountedjv in said grooves and norinally closing said front wall.

In testimony whereof, I afiix iny signature.
