RADIATOR FOR GAS HEATING BY INGANDESCENCE.

- Application filed April 22,

To all whom it may concern:

Be it known that I ANDRE GARBARINI, engineer, citizen o1. the Republic of France, residing in Oourbevoie, Seine, France, and whose post oliice address is23 Rue de Colombes, have invented certain new and use ful Improvements in Radiators for Gas Heating by Incandescence; and I do hereby 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 same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. p

This invention relates to improvements in the construction ofradiators for gas heating by incandesce'nce making use of a gas mantle of the type known as inverted mantle, which is placed. in the horizontal position at the focus of a parabolic mirror.

To provide for the proper working of such radiators, it is very important that the man tle should be disposed onthe axis of the mirror and maintained. in an elastic manner. For this purpose the claws of the ring carrying the mantle are well. fitted upon plane surfaced lugs formed upon the steatite or porcelain burner and are held inan elastic manner in this position by the pressure of a metal ring acted upon by a spiral spring.

The use of the ordinary inverted burners placed horizontally in heating apparatus does not give quite the desired results as concerns the heating action, because the gas and air mixture rises tor the greater portion to the upper part ofthe mantle which will be-' come overheated while the lower parts are only slightly heated, thusshowing an irregular incandescence on the surface of the man tle. In order to obtain a regular incandescence upon the whole surface of the mantle, the latter is mounted upon a burner whose gas mixture outlet end is provided with holes at the upper part, whilst the lower part is bevelled, so as to cause the greater part of the gas mixture to proceed to the lower parts of the mantle, thereby producing the complete incandescence of the mantle. Furthermore, the gas and air mixture should be properly adjusted in order .to provide for the emission'ot red orinttra-red rays which give the maximum calorific. eiliciency, and for this purpose the mantle is also construct= Specification of Letters Patent.

ed with meshes which are wide as well as thick.

Other improvements in the construction of these radiators will be set, forth hereunder.

' In the accompanying drawings:

Fig. 1 is a side view,'partly in section, or the whole radiator. f i

' Fig. 2 is a front view of the same.

Fig. 3 is a longitudinal-section on a larger scale shewin g the air and gassupplyingelement, the burner and the special mounting of the gas mantle.

v Figs. land 5 are also vertical sections on a larger scale of the jointed supporting base. Fig. 6 is an end view ofthe burner.

The radiator comprises a supporting base 1 whereon is pivoted at 2 an arm 3 which is secured to the parabolic reflector a. To the arm 3 is secured the nib 5 which serves to connect the flexible gas admission tube, the gas passing through a cock 6 and proceeding thence to the regulating chamber through the small tube 7. The disposition of the nib 5 adjacent the joint 2 of thereflector will produce only a slight movement of the fiexible tube in all positionso'f the reflector 4.

On the axis of the reflector and'at the'rear of the latter is secured by means of screws a metal socket 8 wherein is engaged a tube 9 forming a mixing chamber at one end whereof is secured the porcelain or steatite burner 10. The tube 9. is fixed in position in the socket 8 by the set screw 11, and it is provided outside the socket 8 with a screwthread whereon is engaged the ring'12- used to regulate the air inlet through the holes 13. When the adjustment has been once determined, the said ring is locked in position by a set screw 14L.

At the outer end of the tube 9 is situated the gas inlet tube 7 which opens into a small chamber-15 having an orifice 16 for the admission of the gas into the mixing chamber 9. The amount of gas to be admitted into this chamber 9 is regulated by means of a screw needle 17 which is locked in position by a set screw 18 after the regulating has been performed.

The gas mantle 19 which is made with wide and thick meshes, is mounted in the usual manner upon a steatite support '20 comprising three attaching claws 21 adapted to engage in the rear of the In s 22 having a plane surface, against which t ey are held in an elastic manner and well in the axis of the reflector by means of a cylindrical ring 23 acted upon by a spiral spring 24: disposed within the socket 8 and at the exterior of the mixing chamber 9.

The burner 10 which is screwed to the end of the mixing chamber 9 is provided at the outer end and near the top with small holes 25 covering about half its surface, whilst thelower part 26 is out on a bevel so as to cause a considerable quantity of the mixture to proceed toward the lower part of theinantle whereby the same shall be made incandescentupon the whole surface, which result would not be obtained were the mixture obliged to flow'through holes distributed in anirregular' manner upon the entire surface of the burner, as the mixture always tends to rise to the upper part of the mantle. The latter; is preferably provided with a smallpiece ofplatinum or palladium sponge forthe automatic'ignition upon opening the gas inlet r The supporting base 1 of cast metalgfor example of aluminium is provided with two lugs 27, Figs. 4 and 5,which are rendered elastic by a saw cut 28 in the head. of the support. They are connected by the pintle 2 whereon is pivotedthe arm 3 supporting thejrefle'ctor, which is preferably of cast aluminium. To obviate gripping action, the snrfacesof the arm 3 engaging the lugs 27 are faced with washers 29 of a different metal, brass for example,'wliich are inserted inthe same. i

The supporting base is also provided at the bottom' part with a hole 30 whereby it may be'placed against the wall by engaging the-said 'holewith a suitable wall hook and is also provided with a hole 31 with gas tap for ceiling suspension by screwing upon a suitable connecting member The reflector d is provided at the front part with crossed protectors in flat metal which are hooked to the beaded rim of the reflector and are twisted so as to afford but a "slight thickness in the direction of the heatrays.
