' Specification of Letters Patent.

Application filed April l, 1915. Serial No. 20,404.

To all whom #may concern.' j

Be it known that I, CHARLES. Srioi-ILER,

a citizen of the United States, and resident of Philadelphia, county oitV lkmniladelphia,V

and State ofrIennsylvanimhave invented a certain new. and useful Improvement in Gas-Burner Attachments, of which "theol--` lowing is a specification. f Y

My invention relates to attachments for.

self-heating gas irons, gas stoves andy the like and has for its object to providean iinproved nozzle arrangement and an improved,

device for operatively connectingy the fuel hose or tube with such irons, lamps, stovesA and the like. My improvement particularly contemplates a construction in which` the efficiency of the iron, lamp, stove or the like is always readily maintained at a maximum point after an initial adjustmenthas taken` place. `The following description will clearly set forth my improved construction and arrangement and the novelty, thereof will be pointed out in the appended claims.

In the accompanyingv drawings `which illustrate an example of mypinvention, Figure 1 is a longitudinalvsection partlyfin ex;-

terior; Figs. 2 and 3 are cross-sections taken respectively on the .lines 2-f-2 and 3.-3 of Fignl and Figfll is a detail exterior view of the nozzle.

As shown in the drawings improvement comprises an air-hood 5 havingthe customary air inlets 6 and internally screwthreaded at 7 for detachable connection with the burner tube of a gasiron, gas lamp, gas stove or the like. The said air hood 5 is further formed with an externally screw*-v threaded neck 8 adapted to receive a sleeve .9 and in addition is provided with an annu! lar flange 5EL against which saidv sleeve A9 is arranged to be screwed. rEhe innersurface of the sleeve 9 in the illustrated example, is

inclined at least throughout a. part of its extent so as to converge toward itsfouter end as indicated at 10, a preferably,'though note necessarily cone shaped coupling member 11 being slidably arranged within said sleeve. formed with a reduced continuing collar 12 which extends'from itsfsmaller endv exteriorly of the sleeve and terminates in an oper? ating head 13 as shown in. Fig. v1, an axial.-

passage 14 extendingthrough said vcollar 12 and coupling member 11 forthe purpose to The said coupling member 11y is be `more fully describedfhereinafter.V The portion 100i the sleeve 9 andthe outer'su'rface of the coupling member 11 if cone' t Patented oet. a, iaiv'.,

shaped are preferably inclined at the same -V angle and said 'couplingl member 11 is formed with a plurality ofapertures 15 in, which balls 16 are located." The apertures 15 are soshaped that the balls 16 are freely movable within certain limits in Van outward radial ldirection against the inner surface 10 of the. sleeve 9 and arel alsoadapted to V project inwardly into` the 4passage 14 wi-thv f out however, being permitted to drop en? tirely through saidapertures 15 in an in'- i ward direction.v A coil spring 17 is located.:

within the sleeve 9v between the vopposed ends of theneck 8 and the coupling member 11,v

and exerts a pressure tending at all' times to movefthe cone shaped or other coupling 'A member 11 toward the converging portion v10 oi' the'sleeveQ. With vthis arrangement' the actionof the surface 10 always tends to 1' force the balls 16 inwardly toward 4the axis,

a nozzle 18ismovably located in theneck 8 and projects through an opening'19 into the airliood 5, the' saidrop'ening 19 "being in' Vaxialv alinement with the passage 14 andi. formed in a transverse partition 2O located interiorly between the said air hood 5 and the externally screw threaded neck Sas shown in Fig. 1. The nozzle 18 is-pr'ovided with an annular flange 21 .arrangedtov slidably iit within said externally screw `.threaded neck 8 to properly maintain the nozzle 1S in 't position therein during its movements in an axial direction. In order to provide a s olid` yconnection between the nozzle 18 kand the coupe-ling member 11 a bushing 21a is located between the iange 21and` coupling memone endv of a coil spring 22 the other end Aot which engages thepartition 20 whereby said nozzle is under a vpressure tending to force it against the bushing 21et and toward the 'e coupling vmember 11 when the parts are the iiange .21 the nozzle is formedwith ya taperingend portion 23 extendinginto the,v

.bushing 212L and adapted, in the .assembled condition-ot the parts, to lit withiny thev in-l teriorly beveled end Vof a tube 2d forming ofthe coupling member 11 as willbefreadily apparent.l In theconstruction as illustrated 4ber llas shown in Fig. 1. The said` flange 21 is also adapted to form an abutmentlfor ioperatively connected as in Fig. 1.v Beyond e' part of or connected With the usual fuel'coiiducting hose 25 which communicatesY with a sourcel oit fuel supply. The tube 2d eX- tends through the passage lll and is held' against' removal therefrom bv the pressure of the balls 16 which exert a gripping-action thereon owing to the fact that the spring 17 exerts a pressure on saidcoupling` member 11 toward the surta ce i9 which latter owing to its inclination forces said balls* 1G into gripping engagement with said tube An attempt-to Withdraw the tube fron? the` passage'li Will said'balls'to move along the surtace` l0 Which' owing to the fac'tthat itA converges toward the' 'free end ,of the sleeve 9; Will force saidl balls `nr'ior'ejv firmly into' Contact withV the tube 24E andl thus prevent ivitlidrafwal thereof in this manner. it the same time the' spring Will maintain theV tapered end of" tliel Vnozzle'l' in' ifirm engagement vvith the tube itj beingunderstood that the bushingv is" of a length to permit this, so that ak fuel" tight connection betiveeir those parts is in this manner' secured at all times When the parts are'v in the aosition sliounV in' Fig.; 1;. When it is desired to disconnect thel 'uel hose fromthel'firon7 lamp, stove or thelike; it is: simply necessary to` move? thecoupling meinber ll inivar'd `against the' tension or' Y tliespringlT-f by exerting apressure o'iithe' operating" heacll`V toward the sleeve 9.

Tliisoperation' vwill cause' the ballsy l5 t'o move inV thereveise direction along the suri ace' l0 which divergesin this direction so' that the grip" of" tlieballs l5: ont'he tube Qflf Will' boreleas'ed ivlierebythe latter is free'` to be Witlidraivn from the passage le@ and roinlen'gagement' withthe'tapeied end 23 ofi thenorfjzle'i'l .lt will be seen that'the lin"-A Wardipressure' on' the head '1%= is exerted' in a natural manner by theA person desiringto disconnect the fuelv hose and an awk:

necessary or desirable. At the same time the means for securing the Vfuel hose in operative connection with the iron or the like effectively prevents the same from becoming disarranged or unintentionally disconnected from any cause. l/Vithfthe4 illustrated ariangeinent forconnecting the fuel hose with the air hood, the air hoodv and its connected parts and the fuel hose and its connected tube are at all times capable. of rotation relatively to each other so that said air hood Vmay be 2 attached to its cooperating burner tube or adjusted relatively thereto while the tube 24 is in position in the passage 141y and thefuel hose is connected with the source v.of fuel supply, At the same time the described arrangement also prevents twisting of or other injury to the fuel hose from this-causeor from any other manipulation of the iron, lamp, stove or the like.V In additionto this the tube 24 rests only on the balls 16 when in operative positionand is spaced from the-.-

inner surfaces of the passage 14 so that con-.I

duction of heat along said tube to the fuel hose is reduced to a minimum and an air space is formed about said tube whereby the.

ily nd the opening 19l in case it leaves same.

, from any cause, thus providing for a proper and readyconnection between the tapering end 23 and the. tube 24 and a proper positioning of the nozzle under all conditions. It will, of course, be understood that the exit end of said nozzle may be other than tapering if desired, this being particularly true if the bushing 21k or other stop is used to engage .the flange 21 for limiting the outward movement of said nozzle. ln some cases the spring 17 may be omitted and the spring 22 alone relied on to properly operate the coupling member 11. When the spring 17 is included it provides for a more speedy operation of the gripping device when inward pressure on the tube 24: ceases and furthermore permits the spring 22 to be kept under compression whereby an absolutely tight connection between the portion 23 of the nozzle 18 and the tube 24 is always assured. I

My improvement is simple in construction and effective in operation and assures a.'

maximum of efficiency in the iron, lamp, stove or other structure with which it is combined. v
