SPECIFICATION vforming part of Letters Patent No. 781,020, dated January 31, 1905. u

` i Application filed February 28, 1904. Serial No. 194,745.

To LUM/hom, t may concern.'

Be it known that I, W" ELLES MORTIMER PAR- TRIDGE, of Peabody, county of Essex, State of Massachusetts, have invented an Improvement in Gas-Stoves, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to gas-stoves or appliances'especially adapted to beplaced in an ordinary kitchen stove or range having an oblong or oval-shaped fire-pot without permanently altering said stove or range, and is intended 'as an improvement upon the gas-stove or appliance shown in my application for Letters Patent, Serial No. 747,474, dated Deceniber 22, i903. Y

My present invention has for its object to improve the construction ofl the appliance to the end that it may be' more easily constructed and adapted to fit iire-pots of different sizes and that the burners may be supported at vregular distances from the side walls of the differently-sized {ire-pots' and a pilot `light y bodying this invention. Fig. 2 is a longitudinal vertical section of the gas-stove, taken on the dotted line 2 2, Fig. 1. Fig. 3 is a transverse vertical section of the stove, taken on the dotted line 3 3, Fig. 2. Fig. 4 is a plan view of one of the burners. Fig. 5 is a detail showing in vertical section three burners and one of the upright supports for the top burner.

Iwater coil or front and the side wall of the iire-pot, respectively, that the burner shall occupy. Fig. 8 is a sectional detail of the uppermost pilot-light. Fig. 9 is a sectional detail of the pilot-light for the two oppositely-disi posed side burners. Fig. 10'is a vertical secand the gas-supply nozzle. Fig. 11 is a detail showing the means for adjusting the air-supply. Fig. 12 is a sectional detail showing the lowermost pilot-light. Fig. 13 is a modification showing a diiferentway of closing the ends of the burners. Fig. 14 is adetail showing the several burners made as half-castings bolted together. Figs. l5 and 16 are details of portions of the burners made as half-castings. Fig. 17 is a plan view of the burner, showing a modified form of top burner and showing means for delivering gas to each side burner separately. Fig. 18 is a vertical section of the'side burners, taken on the dotted line 18 18, Fig. 17. Fig. 19 is a perspective view of a water-front which may be employed. Fig. 20 is a longitudinal vertical section oi' the water-front shown in Fig. 19, taken on the dotted line 20 20. Fig. 21 is a transverse vertical section of the water-front shown in Fig. 19, taken on the dotted 'line 21 21. Fig. 22 is a detail of one of the iittings of the double coil of the water-front.

c@ represents a gas-supply pipe having at one `side a plurality of openings'into which the shut-off valves a', a2, as, and a4 are screwed, each shut-ofi valve having lsecured to its case a nozzle a5, (see Fig. 10,) which projects into i the enlarged end b of a pipe which delivers the air and gas to the burners, four such deliverypipes 62, b3, and b4 being herein shown. The enlarged end Z2 of each delivery-pipe is made conical and forms a mixing-chamber, and upon the outer end oi' each conical end portion I) two plates are placed, which are disposed one upon the other, one of said plates, as c, being rigidlysecured to the end portion I) and the other, as c', having a marginal lip or flange formedion! it, lwhich overlies and loosely engages thefplate c and is thereby free to revolve on said plate c.- Both plates c and 'c' have several circular or other shaped holes through them, and as the outermost plate c' is turned relative to the iiXed plate c air-inlets of greater oi' less dimensions will be provided.

A pair of burners are provided at the top of the appliance, which consist of a horizontallydisposed tubular casting al', having semicircular end portions', and a pair of parallel side portion.

portions provided with transverse walls 672, lo-

cated at points intermediate therein to thereby form two separate tubular compartments, and jet-orifices 67 are provided along the upper surface of." the semicircular end portion and along a portion of the side portions, as best shown in Fig. '1. Two tubular transverse portions 675 CZ are formed integral with the casting 07 near the middle, which respectively connect with the tubular compartments Z3 C74. A vertical pipe e leads to the transverse portion d5, the upper end of which is shouldered to provide a reduced neck c or end portion which is adapted to fit into a tubular projection or boss e2 on the transverse portion, and a setscrew e3 is provided for holding t-he pipe c in any adjusted position relative to the transverse The lower end of the vertical pipe e has fitted into it the reduced neck or eXtension e4, formed on a horizontal pipe e5, being held in place by a set-screw e, thereby providing for vertical adjustment of the top-burnn ers, and the pipe b2 is fitted into the opposite or outer end of said horizontal pipe e5, being held in place by a set-screw @7, thereby providing Jr`or\horizontal adjustment of the enlarged end portion ci. The pipes e5 and e deliver the air and gas directly to the transverse tubular portion 675 and consequently to the tubular compartment (Z3. A similar Vertical pipe f leads to the transverse portion CZ, the upper end of which is shouldered to provide a reducedneck or end portion which is adapted to fit into a tubular projection or bossjl2 on the transverse portion, and a set-screw f3 is provided for holding the pipe f in any adjusted position relative to the transverse portion. The lower end of the vertical pipe f has fitted into it a reduced neck or extension ft, formed on the horizontal pipe f5, being held in place by a set-screW-f, thereby providing for vertical adjustment of the top burners, and a pipe 723 is fitted into the opposite or outer end of said horizontal pipe f5, being held in place by a set-screWf7, thereby providing for horizontal adjustment of the enlarged end portion b. The pipes f5 and f deliver the air and gas directly to the transverse tubular portion d, and consequently to the tubular compartment di. Adjustment of the pipes can be readily made by simply loosening the set-screws and moving the parts, whereas in the application above referred to, showing screw adjustments, much difiiculty has been encountered in adjusting the parts, as the several pipes had to be adjusted practically at the same time and the distance between the top burners d and the stove-lids remained a constant after the appliance was once installed, thus giving no chance to adjust the burners according to the draft, so as to get perfect combustion and maximum heat from the burners.

The side burner g consists of a tubular casting integrally closed at its ends or plugged, as shown 1n Fig. 13, and having a row or' jetorifices along one side, and said casting has formed on it a tubular projection or boss into which is fitted a vertical pipe y, which is held securely therein by a set-screw (1. The vertical pipe g2 has fitted onto it or formed integrally with it a short horizontal pipe g4, into which is fitted a delivery-pipe 7;', which is formed with an enlarged end portion 7). r[`he burner g is thus vertically and horizontally adjusted. The burner r/ has formed integral with it a plurality ot` slotted ears Q20, which receive the supports for the burner in an adjustable manner, whereby the burner may be fitted to fire-pots of different widths. As the jet-orifices are located at the side of the burner, it is important that the burner be held a short distance away from the water-front for the latter to receive the maximum amount of heat from the lateral gas-jets, and therefore I have provided the burner with laterallyprojecting lugs (/4", which are shown in Fig. 6 as short screws screwed into holes in the burner, and in Fig. 7 I have shown said lugs or projections formed integral with the burner. I may provide the burners with lugs of either form and may employ as many lugs as desired.

The water-front herein shown consists of a double coil of pipe w, (see Figs. 3 and 19 to 22,) which is connected at the ends by suitable tittings w with the inlet and outlet pipes, and said coil of pipe is contained within or inclosed by a jacket or casing mi, which is open at the bottom, and one side wall of said jacket or casing has an outwardly-projecting` lip w3, which extends over the side burner f/ and which directs the heat to the coil of pipe. The jacket or casing has holes fw" at the top. The jacket or casing may be covered wholly or partially with asbestos sheeting.

The burners 7L, though two in number, are connected together so as to really constitute a single burner and are located at the side of the fire-pot opposite the burner (l, so as to heat the oven, and said burners each consist of a tubular casting closed at the ends integrally or with plugs and constructed substantially the same as the burner g, each having a plurality of slotted ears 7L'. Each burner 71. has a tubular projection or boss 71,2, into which is fitted a short vertical pipe 75, said short pipe being held therein by set-screws 71., and a horizontal pipe 7L is provided, having a tubular projection or boss above and below, into which said short vertical pipes are also fitted, being held therein by set-screws 7a, and said horizontal pipe has fitted into its inner or front end a delivery-pipe 724, which is held therein by a set-screw. rlhe air and gas are thus delivered to both burners 7L 7L. As these burners are adapted to be held at the proper distance from the oven-wall of the fire-pot to heat the oven, they also have jet-orifices at the side and are provided with latcrally-projecting lugs 71.7.

As supports for the several burners two IOO ITO

therein by a set-screw 254.

at right angles near its lower end, (see Figs. 3-

stands m n are provided, 'each consisting of a base adapted to rest on the bottom of the ashpit and an upright bar rising from it, screwthreaded for a portion of its length and made of a diameter to pass freely through the slots in the ears on the burners, and nuts m n are placed on said uprights above and below said ears. these stands, being adjustablethereon vertically and also horizontally. Upright bars-0, two in number, are located between the burner g and the uppermost burner 7L; which vare screw-threaded at each end, and the lower ends of said bars pass through the slots in the ears on said burners and have placed thereon suitable nuts 0 above and below said ears, and the upper ends of said bars pass through holes in the ears 02 on the uppermost burner, and nuts 03 are placed on said bar above and below said ears. The upper ends of the bars o are slotted to receive a screw-driver. By

4means of the upright bars 0 the uppermost burner is supported in an elevated position and is also independently adjustable to different elevations, so as to bring the top gas-jets to the proper distance from the top of the range.

The pilot lights or burners', which are pirovidedfor the several burners, are constructed as follows: t represents a horizontal pipe which leads from' the gas-supply pipe a and has connected in it a by-pass valve t.' of any usual or lsuitable construction. A vertical pipe t2 has formed in it a horizontal tubular extension t3, which is adapted to receive the end of the pipe ,'which latter is securely held and 12,) and the end of said pipe is closed except for a small hole or jet-orifice 5, for the gas.

rIhe lower end of the pipe t2 is directed toward and terminates near the vertical wall of the lire-pot above the lower burner 7L, and the gas which rises from said lower burner 71, crosses the path of the flame issuing from the jet-oriiices 15, and hence becomes ignited. 4 The lower end of the pipe 152, having the jet-orifices t5, therefore serves as the pilot light or burner for the lower burner it. The upper end of the pipe t2 has iitted into it a short pipe t6, which is held securely therein by a set-screw t7, and the upper end of said pipe t is iitted into the lower end of a vertical pipe t8, which is formed or provided with two tubular projections t t1", which extend in opposite ways, each of said projections having a closed end eliicept for a small hole or jet-orifice, as .1512

jet-orifices, serve as pilot lights or burners for the upper burner 71, and the'burner g and are directed toward the'oppositeside walls of the fire-pot just above said burners, and the'gas issuing from said burners /t and g crosses the path of the flames issuing from the pilot lights or burners t9 151 and is thereby ignited.

The burners g /t L` are supported by' The pipe t2 is bent The tubular projections t tw, having the Into the upper end ofthe pipe t8 'a pipe t is tted, which is held securely therein by a setscrew, and a cap 1515 (see Figs. 3 and 8) is e screwed onto the upper end of said vpipe t, which is formed or provided with two jetorices t1, leading in opposite ways, slanting l upward and outward. The kupper end of the pipe t terminates between the parallel side bars of the uppermost burner and at an-elevation, whereby the cap 15 occupies a position below the top of said burner in order that the lighted jets of gas issuing therefrom shall not be extinguished by the products ofl combustion from the burner g as said products pass over top burners d, and theame issuing from the jet-orifices t1 passes across the top of said uppermost burners, being directed toward the jet-orifices of said burners, as shown in Fig. 1, so that the gas issuing from the jet-- orifices of said burners-will be ignited. By constructing the pilot lights or burners in this v manner it will be seen that thesame are vertically and vhorizontally adjustable throughout, so as to be moved into relatively correct positions for use inconnection with the several burners. l

Herein many of the parts are referred to as pipes; but I desire to include within the meaning of said term any form of tubular casting.

Instead of making the burners as cored castings they may be made as half-castings, as shown in Figs. 14:, 15, and 16, the'parts being bolted together and cement interposed between them, if desired. The top burner Z may be made as a casting having the jet-ori- {ices arranged in elliptical form, as represented in Fig. 17, and in such event the transverse IOO jet-orifices may be made as separate burners,

as shown in Figsfl? and 18,each having a separate delivery-pipe leading to it.
