PILOT BURNER.

1,366,591. Patented Jan. 25, i921.-

Uhll'lii STATES OFFICE.

LEONARD PASSI-SNO, OF BALTEMORE, lyARYLAND, ASSIGNR T THE CITIES ILLUMI- NATING COM'ANY, F NEW' YORK, N. Y., .f COBOBAT'ION OF NEW YORK.

PELT-BURNEB.

Application filed May 1, 131i.

To all w 710m it may concer/a l Be it known that l, LnoNann PassANo, a citizen of the United IStates, residing at Y pilot burners "or lighting gas lamps.

The pilot about to be described is of the type shown and described in my application Serial Number lfi), tiled February 3, 1917, or what is termedA a glower pilot, wherein the glow is designed to keep a considerable area oi' the mantle in a state ot constant incandescence, troni which portion, the gas is kindled, without the usual disruptive 'forces incident to other pilots, but since the present invention does not reside in this teature, it will not be dwelt upon here.

The pilot burner about to be described, is especially adapted for use with inverted mantles, and the primary object of the invention is to provide a pilot which, while capable` of being` maintained suliciently close to the mantle to produce the proper kindling of the gas, will, at the same time, be capable of being readily moved from normal position to permit the replacement ot mantles of the inverted type of burner i and to also permit the replacement of shades, when shades are used, and which will in no way interfere with the shades when the shades are in place around the mantles. Y

A further object oi the invention is to provide a pilot in which the pressure oi the gas for the pilot burner is regulated at a point quite close to the Jfuel opening, thus getting the advantage of the pressure in the gas main, and rendering the pilot susceptible to variations of gas pressure.

in practice, l have found in the use of pilots either glower or gas flame, that the pilot has to be maintained close enough to the mantle under normal conditions, to lrindle the gas when the main ilow comes on, and under such conditions, the top of the pilot burner interferes with the readj,T replacement of shades and mantles.

The invention about to be described completely overcomes this disadvantage, and a pilot burner is produced in which, by a very simple manual manipulation, the end of the pilot tube is moved entirely away from the less Specification of Letters Patent.

Serial No. 165,679.

mantle, giving plenty of room tor replacement and adjustment of the mantle upon the burner.

Other objects and advantages of the invention will become apparent in the course of the following description.

ln the drawings- Figure l is a iront view of the pilot applied to an incandescent gas burner of the inverted type;

lfig. 2 is a perspective view of the pilot burner of the double type, designed to light or lrindle the gas of two mantles showing one of the pilots in dotted lines, moved to the middle, or to a position where it will not intertere with the'replacement of the mantle.

3 is a partial section of the pilot.

Referring to the drawings, the numeral 1 designates two gas burners, which may be oit any approved type, and to which is attached mantles 2, both burners being supplied through an ordinary burner tube 3, which may be attached to a gas cock 4, which is oi a type well known, and in common use, especially in connection with street lamps, and which embodies a construction in which there is a by-pass which supplies the gas iter the pilot light or burner.

The numeral 5 designates the pilot tube, which is threaded at its upper end as indicated at 6, for the reception of a double hollow T-union T havingA laterally threaded bosses 8, having channels 9 therethrough, communicating with the chamber 10 yof the union. ,v l

Since the Vattachments to the union are identical on both sides oi the pilot tube, and Tunion, a description of one will serve as a description of both.

The numeral 11 designates an internally threaded sleeve, of exterior angular Jformation for the reception of a wrench, by which the sleeve may be adjusted for the purposes that will presently become apparent. 1Within this sleeve, and having preferably, although not necessarily, a head 12 is a short tube 13, which is threaded or otherwise secured to a hollow connection 14 having bosses 16 and 16 at its upper and lower ends respectively. The tube 13 has a channel 17 which establishes communication between the connections 7 and 14. The connection la is provided on the inside with a seat 18, for the end of the needle valve 19, the lower portion of which is threaded as indicated at 2O and passes through a threaded opening in the bottom of the connection, and is provided on the outside with a Vmilled head V2l, by which obviously, the valve may vbe operated to more or less open orjclose the channel 22, which communicates with the pilot nipple 23, which is provided near its upper end, with Ya laterally extending fuel outlet 24. Around the top of the nipple, and secured thereto, in any suitable manner, 1s a wrapping of mantle material 25, or a mate- Y rial capable of being` brought toV a state .of incandescence, or material commonly' -used for mantle purposes. As above suggested, I prefer to'provide the tube 13 with a head 12, which is snugly fitted in the sleeve i7 and permits of gas-tightpacking, and the connection is such that when the sleeve ll is adjusted, the Vouter end of the member 8 will force the head and packing snugly against the inner walls of the sleeve, thus eflfectually preventingl the escape of the gas,

while at the same time, it will be understood that the .sleeve adjustment is suchas to per- Y mit the connection 14:, and parts carried thereby, to be rocked in either direction with relation tothe fixed pilot tube 5 and T-connection.

The position shown in Fig. l is normal position of the `pilot nipples wherein they are in vertical position, and in quite close proximity to the mantles for the purpose, as before intimated, of keeping a certain considerable area of the mantles in a state of f position shownV end of the sleeve, a tube extendinginto said Y sleeve and in communication with said hollow member, a hollow connection carried by the outer end of the tube, a pilot nipple carrie by saidconnectiomand having a fuel outlet its upper end, and means for controlling, within the connection, the flow of ,gas tothe pilot nipple. Y

2. A1 pilot burner comprising a pilot tube having a hollow connection secured tothe top thereof, an adjustable sleeve. carried bvl the hollow member, aV tube extendinginto he sleeve and having communication with the'hollow member, a connection carried at the outer end of the tube, a `pilot nipple carriedby said connection, and having a fuel outlet at its Vupper end, and a. needle valve working` within said connection and adapted to control the'flow of gas to the fuel nipple.

3. In combination with a mantle, a pilot burner comprising, a fixed portion through which a supply ofgas maybe feder stuiling' box carried by the router)V end of the lixed portion and a` delivery portion having a headed portion in the stuffing box and normally maintained in ploseproximity to the mantle, whereby the delivery portion is adapted to be moved away from the mantle,

. for the purpose described.

4. ln combination with two vertically disposed spaced mantles Varranged in a horizontal plane, aV vertically disposed supply pipe adjacent thereto, a cross-head carried by and in communication with the upper end of the pipe,`and a vertically disposed `pilot burner carried by each end of the cross-head and adapted to Swingin a vertical :plane so as to. bringthe pilot burners to or from the mantles.

ln testimony whereof I aflix my signature in presence of two witnesses. i V y p LEONARD PASSANO.
