GAS-BURNER Application filed June 3.,

Specification of Letters Patent.

Patented July 23,1912, 1911 Serial No. 631.144.

To all whom it may concern:

Be it known that we, \VILLTAH XV. KEMP and WILLIAM H. VAN Hoax. citizens of the United States, residing at Baltin'iore. in the State f Maryland, have invented new and useful Improvements in Gas llurnere, of which the following is a speritit'ation.

This invention relates to a gas hnrner of that type having a plurality of jets emanatin; from a single as pipe. and tle igned p *irnarily for use with gasolene gas. or a gas produrtrtl h) mixing air with a hydro rai'hhn vapor. The burner iS alszo ver ellirient when u e l with retort, prodtn-er, natural and other ga es.

()ne ohjeet of the invention to provide :1 humor of the above mentioned type with nipples of novel. ronstrut-tion for the outflow ol' gas to he horned, which are peculiarly adapted for u-e with asolene gas in that they are Illllt, to sustain the flame of such 21 eont nuouelv without danger of it, hein; blown out hv its own pressure, a fault com m n with other hurnerel when using gasd leni- :1 1 under pressure.

\n lher olijet-t of the invention to provide a water jaeltet for the gas burner, through whioh jatket a stream of water is desiJned to flowwvhen the luirner i ignited tor the purptw of keeping down the tem prraiure 0t Fflltl hurner whirl; would, other i .-i heroine intensely hot and lead to more le injurv ol' the nipples. l'-urthei'm0re, int-new without the waterjat'ltet warp or how upwardly und r the intense heat. tln-rehy musing" the [lame in the renter of lln luirner to he nun-h neartr the surface lleing healed than the flame at the end of the burner. giving an uneven heat. This is due to tun-veil expiurdon of the burner, thelame I atthe top ol' the burner living in eontac't wilh the metal strnvture thereof. muses the hurner to expand more on the top than on the llottom. with the result that the hurner how as stated. The Circulation of water through the hurner overt-tunes thin di ;tor-- tion and also protects the hurner fr m rellfitittl heat. whit'h is very lentrur'tive.

\nother advantage of this burner i:- that, hwnuse of il peculiar eonetruetion, it will hurn a much thinner gas than is ordinarily uee l, ronenniiug leSs oxygen when placed in an inelosing ehamher than the ordinal hnrner. and, as the gas is so thin, and containe so much air or oxygen, the combustion can he foreed and a high flame temperature l attained with a very small volume of tire.

With these and other ohjeets in view the invention consists in the novel eonstuwtion, arrangement and combinat on of parts hero inatter desurihed, and particularly pointed out in the Claims, reference being had to the acrompanying drawings, in which Figure l is an exterior View of one form of the improved hurner surrounded by a water jacket, Fig. 3 a central longitudinal s ional view of one end of the l'mrner .--ituatetl within a r-nlender roll. Fig ('rosseectional -.l0\\ on the line 3 3 of Fig. 1. Fig. 4 its a eentral sectional iew enlarged speetive View of the slotted diaphragm loiock which forms a part of the burner nipple. Figs. 6, 7 and R :ireyiews in cross section of modified forms of the burner.

Similar numerals of reference are used for the same parts in all the figures.

4 In the drawing, the numeral 10 denignates a pipe or manifold into or through which gas may pass and iiow out for ignition by Way of a pluralihv of short nipples or hurners 11. threaded thereinto and projecting from the side of said pipe. The gas pipe or manitold 10 may be straight, as represented, or of other desired or convenient Form.

Each nipple 11 is preferahly tapered slightly from its outer end inwardly to a shoulder 13, from whit-h latter projects a threaded "stem 14 :-crewed into an opening in said manifold, laoh nipple has a straight hot-e t5 extending thereinto nearly to the line of the shoulder 13, from n'hieh point; the bore continues, bu is of less diameter as at 6, nearly to the and of ti." stem 14, through which end is made a small perform tion lti' into the redueed bore i to admit gas from the manifold into the nipple. The bottom of the bore 15 forms a mat or stop 18 against whi h rests one end of a relatively thick diaphragm hlook l9, 'titting tightly in the bore 15, and provided with a numlier of longitudinal elots 20, extoi'iding from the peripheral surtnoe of Said block radially or if desired, tangential to a tirt'le eonrentrie with the axis: of the block and from end to end of the same. A small, hole 21 may he made through the (enter of the hloelr 19 if deeired.

line from the manifold 10. passes: into the everal nipples ll, through the small open of one of the burner nipples, Fig. 5 is a perlug} ll. and th nce through the several slots il in the block I!) to its outer end where itis ignited. the nipple it extends beyond the diaylnuogw u'ovl; lll nnd t wns a combustion chuznliri ot the outer end of the here 15 that protect the llazne from extinguislnnent hy external drafts or air currents; and hecause ot' the 'l awt that uuhustion takes place within the horn 1.3, the ilztlnc can he delixered llll lt'l a h avy hlnst which w uld he impossihle were the (Xttllfil' fact of the diaphragm hlock and the outer end of the nippic in the same plane: r were the gas ig-- nitetl at he endot the here instead of at he e; ot the diaphragm block. The openings 17 in the lower ends of the nipples are made sm ll, their cenihincd area. being much less than the cross-sectional area of the manifold 10, the effect of which is that the gas will he introduced into each nipple under the same pressure, each tube thus eonsuming the nne volume. oi'gas in a given time with the result that. a uniform flame and temperature throughout; the entire length of the hurner is obtained. here the openings 17 large the gas would back up in tho far end of the humor and cause the flame on that end to i=6 much higher and more intense than on the supply end,

Practical denmnstration has shown many advantages gained hy the use of a. relatively thick dltllillll'llgl'l] provided with longitudinal grooves or kerfs instead of a thin par' tition made of perforated or slotted metal or wire gauze, which forms are in common use at the present time. Among the advantages may he noted the fact; that hy the use 01" a thick diaphragm the burner does not,

get so hot as when a thin one is used, and furthermm-e that a thin sheet metal or gauze diaphragm will he quickly (lestroved hy the heat of the flame, wherea a thick dia phragm such as shown in Fig. 5 will not. he atlected by the intense heat. The flame holds to the thick dihphrimm better than to a. perforated or sawed disk and is rarely hlown out by the pressure of the gas. With the disk construction, however, the flame is blown outquickly and very often. The thick diaphragm furtherrnme will last a long while because of its troedo1ntro1n destruction hy the heat oi the flame.

Surrounding the manifold [0 in the construction shown, is a water ia 'ket or casing 25, spaced :1 short distance from the manifold and pr vided with heads 26 and 27 with a water inlet and outlet 28 and )9 resl'u'ectiw-ly. ln the constrmvtion shown in Figs. 1 to 4, a plurality of tapering holes are made through the wall of the. water ja ket. 35 to reoeiw the nipples 11, which are passed through said holes and screwed into the manifold when the parts are assemhled. For the purpose of retaining the manifold and "water jacket. in proper Ielation to each other and form water tight joints between the nipples and the openings in the water jacket through which they pass, a plurality of screws 30 are threaded radially in the water jacket on opposite side. of the nipple and hear at their inner end. against the manifold (0. By tightening these screws tho manifold and water jacket tend to separate and as the nipples are at tached to the maniiold they will he drawn inwardly so that the tapering outer surfaces of the nipples will he firmly seated in similarly tapered holes in the water jacket and close said openings tightly against the passage therethrough of the water in the water jacket.

Instead of making; nipples with exterior walls diverging at their outer ends away from the axis of said nipples, they may be made converging as in Fi 6, to tit. similarly inclined openings in t e water jacket 25 In this the screws 30 bear against the under side of the manifold 10* to force the nipples ll into the openings in the water jacket. Another form of nipplc is shown in Fig. 7. In thisinstance, the nipple t1 converges from about its center toward each end and the holes in the manifold 10 and 'ater jacket 25 are made ta poring to correspond with the taper on the exterior of the nipple. When the screws 30 below the manifold, are turned in the proper direction said manifold is forced upwardly and causes the nipples to seat themselves in their respective openings in the manifold and water jacket. The nipples may also he made as in Fig. 8, where it will be seen that the nipples 11" are threaded into the water jacket 25 and have their lower or inner ends converged to seat themselves in similarly shaped openings in the manifold 10. The screws 30 are, in this instance. also placed below the manifold to force the same upwardly to produce a. tight joint lu twecn itself and the nipple.

The nipples are cheap, simple and very efticient and consist of two parts only, the nipple proper ll and the diaphragm block 19. the. latter being madc to fit so tightly in the horn of the nipple as to require no other fastening means. The slots Qt) therein are made very quickly and without trouhle With a saw or other tool.

Fig. 2 shows the improved burner applied to a calender roll used in textile finishing plants and paper mills, where experience. has demonstrated that the etriciency of such rolls when so heated greatly exceelt the present method of heating these rolls by steam, which cannot. raise. the temperature of Said rolls ahove a certain point, but with gas these rolls can he heated to and maintained at any desired. temperature. Gas burners have not.- heen used extensively for heating calendar and similar rolls fromwithin the rolls, because there never yet has hccn a, hurner which could resist the intensity of the heat hy which it is urrouinled.

and there never has licen a lmrner. o tar as known capable of utilizing; a very n and make Such good wanlaistion and even heat as is necessary and tltw'lltt'l. improved burner ahow de llied sur rounded by a \iater jaek i. an intense heat an he maintained Wllllullt detriment to the hornet and perfectly adapted to ('Ullhllfill'} a rery thin gas.

It. is to he distin tly understood that the diaphragm hlock li and the nipple or hnrner j/("I' at; of which it forms a part. herein shown and do in the present applieatioir as it. forms the suhject matter of a separate application tiled by as on the 18th day of January, lilli, Serial No. 671.907.
