of gas lamps, the novel features of the invention'being particularly suited to multiple: burner lamps of the inverted type.

The invention resides in the several tea-v tures'l'iereinafter particularly described and claimed and embodied in the lamp illus-l trated :in the accompanying drawing in; which Figure 1 is an elevation of a multiple burner gas lamp in which the casing and;

globe are shown in section exposing theinterior; F ig. 2' is a sectional view of the. burner, manifold and connected. piping; Fig. 3 is a" section taken in the direction of; the arrows on line 33 of Fig. 2; and Fig. at is a section taken in the direction of the arrows on line H of Fig. 3.

Referring to the drawings, the lamp is supported by the supply pipe A which is.

screwed into the upper endof a fitting B,-

the lower end of which fitting in turn screwed into a tapped hole in the center of a bridge n extending across the lower half C of ahollow manifold ring which is preferably concentricwith the pipe A- A plug l) is screwed upwardly into the tapped hole in the bridge a and serves as a closure for a well 6' in the fitting B the purpose of whicn. will be more -t'ully described hereinafter. A suitablenuniber of nipples E are screwed, into bosses on the under side of the lower half C of the manifold, these nipples E being equally spaced about the ring and I provided upon their lower extremities with "refractory burners'F upon whlch inverted mantles G are placed. .Anuppcr halt D of the manifold ring is placed 'upon the lower half C, an annular screen H benig interposed between the two halves dividing the annular space within the manifold into upper and lower chambers. The two halves C and D are securedtogether by a suitable number of screws (Z.

Acasing is provided for the lamp which casing consists impart.

of a cylindrical flue or'cltimney I which extends upwardly from a point justabove the burners F andincloses the ring manifold and nipples E. An ornamental: hood J surrounding the lower end. of the flue I serves to hold a glass globe K. Perforations j are provided in the hood Jim thejexit of heated air anda small perforation hat the lowermost part of the globe K affords entrance for air to the globe. heat bell L is sup ported on the supplyjpipe A some distance above the'upper endof the-flue I. An air funnel M of axbunsen. has a threaded end which is passed through'an aperture in the wall of the duel and isscrewcd into a boss on the upper halt D of the manifold ring and this funnel is provided with air inlet apertures which may rbeclosed or opened. to

any desired degree by. the rotation of a shutter m mounted upon the, funnel.

' A valve housing N is'coniieo'ted to. the air funnel M by a threaded nipple-O which is provided with a jet opening "adapted to be regulatedby the needle valve P threaded into the housing Niin alineinentwith nipple O. A cock Q is mounted in tlievalve housing N to-open and close a passageway V which communicates with the jet opening in nipple O. The outer end of thepassageway V is closed by a threaded plug a which. may be removed to give access to the passageway V in order that ittmhy; be cleaned. A pipe R is screwed intothe valve housing N and opens into the passageway V abovethecock Q. This pipe passes through an opening in the Wall ofthe line I and is connected by a union 7' to the upper end of ,the'fittingB. The casing is mainly supported at the junction of the funnel M and the inanifold ringv and by a bridge piece 8 at the top of the fine I engaging the'pipe A.

A pilot light leads from the passageway ice eway V during alternate downstrokes is nio'untby' the lever X engages one tooth of the ratchet-U and turns the cock Q one-quarterv revolution each time the lever X ismoved downwardly. The lever X is automatically returned by a spring Y after each downward movement.

The manner in which the gas is led to the burners is as follows: Flowing in through the supply pipe A the gas is directed into the well 5. where any particles that may have been carried by the gas collect and are not carried intothe needle valves and small parts from which their removal would be troublesome. In order to remove such particles and dirt as may from time to time c01- lect in well I) it is only necessary to remove plug 6 which is'so located as to be easily accessible. After having deposited any dirt or particles that it may have carried, in the well 6 the gas flows through the pipe R into the upper end of the as sageway V.. From this point gas ows through the adjustable needle valve T to the pilot light pipe and the flow of gas to the pilot light is not interrupted by the operation of the cock, Q. However if at any time it is desired to discontinue the supply of gas to the pilot light this can be done by entirely closing the needle valve T. The supply of gas for the burners is admitted to the lower end of thepassageway V when the cock Q is 'openpd and passing by the needle valve P is directed through the air funnel M and from thence passes together with a suitable quantity of air drawn from without the casing of the lamp, .into the manifold ringabove the screen H; The chamber within the manifold ring and above the screen H first fills with gasand air distributlng the gas" and air before they pass downwardly through the screen H and even distribution of well mixed gas and air is assemblage the down the nipples E efiected by the time the mixture reaches mouths of and passes leading to the burners. The relatively large area of the screen H permits the mixture to pass quietly to the burners and prevents roaring. It will be noted that the arrangement of the several parts as shown is peculiarly advantageous in lamps of this character, affording central support by the supto the drip and dirt thoroughly practical of the principal parts, well adapted to the ornamental designs so essential in this type of lamp.

It is obvious that various minor changes collecting well and a in form and detail may be made Without departing from the spirit of the invention.

Having thus described my invent-ion what I claim is:

1. In a gas lamp, the combination of a supporting vertical gas supply pipe, a catch-all well forming a downward continu ation of said supply pipe, a burner having a same,

supporting member provided with an opening having a removable closure in the lower end 'of said opening, said catch-all well being connected with the upper end of said opening in the supporting member, whereby access may be had to said catch-all well, substantially as described.

2. In a gas lamp, the combination of an upright flue, a gas supply pipe extending downwardly into said flue and terminating in a well, a ring manifold surrounding said Well and supported therefrom, a branch gas duct leading laterally from said supply pipe through the wall of said flue to the outside thereof, an air and gas duct leading from outside said fluethrough the wall thereof to said manifold, and controlling and mixing devices located outside said flue and connecting said ducts; substantially as described.
