Description
H. H. DAVENPORT. PROTECTOR FOR PILOT LIGHTS.
APPLIOATION FILED FEB 27, 1913.
ur union HARRISON H. DAVENPORT, OF TROPICO, CALIFORNIA.
IPROTEC'TOB FOR PILOT-LIGHTS.
Application filed February 27, 1913.
To all whom it may concern:
Be it known that I, HARRISON H. Davenronr, a citizen of the United States, residing in the city of Tropico, State of California, have invented a new and useful Protector for Pilot-Lights, of which the following is a specification.
An object of this invention is to provide improved means readily adapted for attachment to pilot lights now in use, for protecting said pilot lights from being extinguished by drafts of air, and also to cause the pilot light to burn with a clearer flame which will be free from smoke or soot.
Other objects and advantages may hereinafter appear.
In the drawings the invention is illustrated as applied to the Stanley type of heating burners for the boilers of self propelled vehicles; but it is by no means intended to limit the invention to such use. It may be applied to various other pilot lights without departing from the spirit of the invention.
Referring to the accompanying drawings which illustrate the invention, Figure 1 is a plan view of a burner of the Stanley type, showing the invention applied to the pilot light, a portion of the vaporizing tubes being broken away to show parts under-- neath. Fig. 2 is a section on line w w of Fig. 1. Fig. 3 is a front view of the burner partly in section. Fig. 4 is an enlarged section on line oc -w of Fig. 1. Fig. 5 is a perspective view of the pilot light protector showing the same detached.
Referring in detail to the drawings within the usual fire box 1 is mounted the angularly corrugated burner plate 2, of well known design having the burner slots 3 cut into the tops of the corrugations. Across the burner casting 1 extend the vaporizing tubes 4 and 5 to furnish fuel to the main mixing tubes 46 and 5 and also a vaporizing tube 6 to furnish vapor to the mixing tube 7 which supplies the pilot light. The mixing tube 7 of the pilot light discharges the fuel mixture into the pilot casting 8 having burner openings 9.
Coming now to the novel features to which the invention pertains, the pilot protector consists, in the embodiment of the invention herein illustrated, of a U-shaped strip 11 illustrated in perspective in Fig. 5, having an outwardly directed flange 12 at each side of its month, said flanges each Specification of Letters Patent.

Serial No. 751,151.
being riveted to the upright wall l of the front fire boX 1. Said strip 11 is of metal or other incombustible material preferably from f; to of an inch thick.
lVhen the main burner is not in operation the side walls of the U-shaped protector 11 prevent the heat of the pilot burner 8 from spreading and cause said heat to ascend against the vaporizing tubes l and 5 of the main burner, and the vaporizing tube 6 of the pilot burner, thus keeping a more uniform heat under the vaporizing tube 6 of the pilot burner, so that the pilot burner is caused to burn at all times with a clear flame, guarding against production of soot. The pilot burner is less apt to be extinguished when the fuel supply thereof is thus kept heated, and a clear flame insured, and this feature in combination with the protection against drafts afforded by the walls of the member 11, guards positively against accidental extinguishment.
In order to provide for lighting the pilot light a match opening 13 is provided through one of the flanges 12 and through the wall 1 of the fire box. On the same level with said match opening 13 is a light opening 14 which leads through the wall of the lJ-shaped protector 11 already referred to. Said opening 1% permits the flame of the match readily to ignite the gaseous fuel of the pilot light, and also enables the operator to see whether or not the pilot light is burning. The wall of the protector 11 may be of any desired height so long as it does not reach the bottom of the boiler (not shown). It is necessary that saidprotector 11 should be at least as high as the tops of the burner openings 3.
The disadvantages of the pilot lights now in use in connection with the burners and boilers of steam propelled vehicles, are that they are frequently extinguished by drafts caused by the sudden starting or stopping of the vehicle, with the result that when the fuel is discharged into the main burner automatically it is wasted instead of producing the desired combustion, because of there being no pilot light to ignite the vapor. Furthermore, while a vehicle is standing the pilot light is also liable to become extinguished, and on account of the boiler losing its heat the steam pressure is lost and cannotbe restored until the vaporizing tubes are first heated by means specially provided for the purpose, and time is taken to produce the required steam pressure for propelling the vehicle. This invention overcomes the foregoing serious defects.
1 claim:
1. The combination, with the corrugated burner plate and the pilot light located between two corrugations thereof, of a strip set up on edge, said strip being in the form of an elongated U, the sides of the U extending parallel to the corrugations of the burner plate and to a point considerably above the pilot light, the open end of the U being provided with flanges fastened to the inner side of the wall 01": the firebox.
The combination with a fire box and pilot burner of a U-shaped strip, the sides of which inclose the pilot burner, the ends of said strip being outwardly deflected and secured to the'wall of said fire box to hold said strip in position, there. being a match opening extending through the wall of thefire box, and through one of the outhent ends of said strip.
8. The combination, with the fire box and pilot burner therein, of a protecting strip extending alongside of the pilot light, there being a match opening through the Wall of sald fire box and an opening through the portion of the protecting strip which is spaced away from the wall of the fire, l
saidlast mentioned opening allowing the v i'uelflto reach the flame of a match inserted through the first mentioned opening. v
In testimony whereof I have hereunto signed my name in the presence of two sub;
scribing Witnesses at Los Angeles, in the Copies lot this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
Washington, D. C.
