' H. cs. CALDWELL PILOT LIGHT BURNER Filed Sept. 16, 1926 Arromvsy l atented Jan. 14, 1930 warren stares PATENT @FFHQE HENRY O. CALDWELL, OF BUFFALO, NEW YORK, ASSIGNOE TO CALDWELL EXPERI- MENTAL CORPORATION, OF BUFFALO, NEW YORK, A CORPORATION OF DELAWARE PILOT-LTEGHT BURNER,
Application filed September 16, 1926.
It is well known to those skilled in the art that pilot light burners of present day design are so constructed that the gas at the place of burning is under its full pressure, with the result that a slight draft or heat, produced by the burner in connection with which the pilot light is used, will extinguish the flame.
It has been a principal object-o1": my invention to provide a pilot light burner which 'can not easily be extinguished by drafts of air or by the heat of the burner with which it is used.
The above objects andadvantages have been accomplished by the device shown in the accompanying drawings, of which:
Fig. 1 is a side, sectional elevation of the preferred form of my invention.
Fig. 2 is a similar view of a modified form of structure.
Referring to the form shown in Fig. 1, my
device comprises a body 5, preferably made of piping and which forms a chamber 6 having considerable volume. Arranged in the bottom of the body 5 is an inlet plug 7 having a very small opening 8 therethrough. The body 5 is provided with imperiorate walls and arranged in the upper end of the pipe 5 is an outlet plug 9. The outlet plug is provided with a longitudinal opening 10 of a diameter greater than the diameter of the opening 8 in the inlet plug. The outlet plug 9 preferably extends some distance above the top of the pipe 5, and a plurality of lateral openings 11 may be provided, which communicate with the longitudinal outlet open ing 10. The flame of the burner burns at the openings 11. V
The body 5 is screw-threaded at its lower end and may be connected to the supply pipe 12, either by a pipe elbow 13, as shown, or a pipe coupling.
In the form of invention shown in Fig. 2, the burner comprises a body 15 preferably of tunnel shape, thus forming a chamber 16, flaring outwardly as it approaches the outer end of the body. The body is carried by a flange 17 which is provided in its central portion with a small gas inlet opening 18. The flange is preferably interiorly screw- Serial No. 135,829.
threaded at 19 for the reception of the supply pipe 20.
It will be seen that in the form of invention shown in Fig. 1, the gas entering through the opening 8 formed in the inlet plug 7 will be permitted to expand in the chamber 6 to a point where it has substantially no pressure. This is brought about because of the fact that the outlet opening 10 is very much larger than the inlet opening 8, whereby the gas is permitted to flow under practically no pressure from the openings 11. It is because of this condition that the light will not be easily extinguished and will burn under most trying conditions.
In the form of invention shown in Fig. 2,
the outer end of the chamber 16 is unrestricted, and the gas coming through the small inlet opening 18 will be allowed to expand to a condition of practically no pressure and will be burned at the mouth of the body 15.
Obviously, some modifications of the details herein shown and described may be made without departing from the spirit of my invention or the scope of the appended claim, and I do not, therefore, Wish to be limited to the exact embodiment herein shown and described, the form shown being merely a preferred embodiment thereof.
Having thus described my invention, what I claim is:
A pilot light burner comprising a body forming a chamber, the body being closed at its supply end to the admission of air and formed with a restricted gas inlet opening at its supply end, and a plug arranged in the outlet end of thebody, the plug being formed with a longitudinal outlet opening and also with a plurality of lateral outlet openings extending from the longitudinal opening, the combined area of the outlet openings being relatively greater than the area of the inlet openings, whereby the gas pressure within the chamber will be reduced to a minimum.
In testimony whereof, I have hereunto signed my name.
HENRY G. CALDWELL.
