To/ll 'whom it may concern:
Be it known that I, FRANK RrBAii, citizen of the UnitedStates, residing at New York, in the `county of New York and State of New York, have invented certain new and yuseful Improveinei'its in Gas Burners, of which the following is a specilcation'.
' The present invention relates in general to gas burners, and has for its object to provide an improved burner embodying a novel construction whereby the mantle is suspended at the lower end .thereof and the fixtures are prevented :t'roni interfering with the lightl as is the case with the ordinary 'burnersI in Acommon use."
A further object of the inventionis the provision of an improved. regulator for controlling tlie supply of gas to the burner and securing a uniform flow of the same.
'lhe invention also has for its object to provide novel means Jt'or detachably securing the mantle to the burner and for supporting a globe which indo-:es the mantle.
For a 'full description of the invention and the. merits thereof and also to acquire a-knowledge of the details of construction and the means tor etl'eeting the result, reference is to be had to the following description- .and accompanying drawings, in which:
Figure l is a vertical sectional view c through a gas lamp embodying the invention. Figa 2 is a horizontal sectional viewA ou tlie'line 2-2 of Fig. l. Fig. 3 is a similar view on the line tlf-3 of Fig. l looking upward. Fig. -l is a detail view ot the collar t'or supporting the mantle. Fig.- 5 is a simif -lar view of the ring applied tothe mantle and designed to engage the collar shown iii Fig. 4.
lori'esponding and like parts are referred to in the following description and indicated in all the views otl the drawings by the saine reference characters.
. lroadly'speaking the former comprises a vertically disposed mixing tube provided at its upper end with iin improved regulator t'oi' controlling-*the supply oit gas, and having an inverted mantle suspended troni the lower end thereof. The gas regulator coinprises a. tubular head l having the lower end thereoie contracted toforn'i a nozzle through which the gars issues in a. jet, a cap 2 being 'i applied tothe upper end 'ot the head and provided With a coupling flange by means of which connection may be made in the usual manner with asupply pipe. The opening of. .the sidesof the cup 3 and the bottom of the through 'the tubular head l enlarged at the upper end Athereof and contracted at the lower end, a cup 3 being received within the said enlarged portion. This cup rests upon an annular shoulder 4 and is provided with ,an annular lip 5 whlch tends to prevent the passage of gas around the upper edge there- A plurality of openings (5 1s formed 1n cup is yprovided with projections 7 which engage the. shoulder 4 and hold the cup spaced theret'roni. It will thus be apparent that thegas 'entering the cup through the supply pipeniust pass through the lateral openings in the cup and circulate around the bottom thereof between the projections 7.
A tubular member S is loosely mounted within the lower port-ion of the tubular head 1, the said tubular member having the lower edges thereof eurvedinwardly and being bifur-l cated to Yt'orin the spring jaws 8a. It will be observed that the bottoni of the tubular member S is rounded so that by forcing the saine downwardly within the head l the spring jaws S 'will be closed and the passafre ot gas throuf li the nozzle shut otf. For t e purpose ol regulating` this tubular member a thumb screw 9 is utilized, the inner end of gthe said screw being-pointed and having a wedge-like engagement with Ithe upper extremity of the member S so that as the screw is forced inwardly the tubular member i's moved downwardly. lit-ith this construction it will be obvious that by suitably inanipulating the thumb screw the irieniber can be moved longitudinally within the tubular head and the jaws S either forced together or permitted to spread apart so as to regulate the lnissage ot' gas into the mixing tube.'h The mixing tiihe 10 is formed in two sew tions having av threaded. connection with eah other` the upper section 10 having the inuth thereof enlargtal and secured to the tubular head 1 while the lower section 1.0"
enlarged mouth of the upper section l()a of the mixing tube is provi( ed with the air inlet openings 12 through which' the air is drawn as the gas enters the mixing tube in the form ofa jet discharged through'the nozzle at the lower end of the tubular head.` The gas and air are thoroughly commingled with each other as they travel through the mixing tube so that perfect combustion is produced as they issue from the discharge tube whichis threaded upon the lower contracted end of a sleeve 14 secured to the' lower end of the ni'ixing tube.
Clamped between the upper end of the discharge tube 13 and the enlarged portion otl the sleeve 14 is a collar 15 formed with the radial arms 1.6 terminating in the lateral extensions 1T, the saitl lateral extensions being provided at their extremitieeL with the upwardly' extending lugs 18. T he mantle 19 is suspended in an inverted position and is secured at its mouth toa ring 2O formed with the upwardly extending hook members 21 designed to detachably engage the lateral extensions 17 otl the radial arms projecting from the collar 15.A Vith this construction it will be obvious that by litt- 'ing the ring 20 upwardly, until the hook members 21 have been elevated above the lugs 18 and then imparting a rotary movement to the ring the mantle can be readily disengaged from the burner. Itwill also be apparent that in exactly the reverse manner the mantle can be applied to the burner.
For the purpose ot' protecting the mantle from injury anin'verted globe 22 is utilized, the said globe being provided with the openings 23 through which air is admitted to the burner. The upper end of the globe is flared outwardly as indicated at 2l and en-' gages a ring 25 which is supported by the arms 26. These arms Yare shown in the present instance as formed integral with a deliector 27 which serves to prevent the heat iiiteilleiingwvith the upper portion of' the mixing tube or the gas regulator. As shown on the drawings the dellector 27 has an inverted bell-shaped formation, the mouth of the deflector being` Hai-ed outwardly and then turned downwardly, the arms 26 being integral with the deflector and constituting extensions of the downwardly turned edge thereof. It will also be observed 'that lips 2S are stamped from and bent upwardly from the edge ot' the deh'eetor to pre nt the accumulation ot' heat within the annular space formed by the. downwardly turned edge thereof. The arms 2G are formed with the inwardly extending lugs 2f) which eu'- gage the globe supporting ring 25, and are provided at their extremities with screws 30 serving to support an exterior ring 31. lt will be observed that in the present instance the lower edge of the exterior ring is returned upon itself and that the arms 2G pass through openings in this returned edge.`
T n theoperation o'l the burner the gas 1 i i l l l l l l l enters the mixing tube through the nozzle at the lower end of the regulator and air is drawn into the mixing tube through the inlet openings 12. The air and gas are thoroughly mixed asl they pass through the tube and a perfect combustion is produced when they issue from the discharge tube 30 into the inverted mantle 19. The mantle is thereby heated to incandescen'ce so as to produce light in the` usual manner, the detiector ,hood 2T preventing the heat from risingand coming into direct contact with the upper portion ot the mixing tube and the gas regulator.
Having thus describedy thelinvention, what .is claimed as new is:
t 1.y ln a gas burner., thecombinatlon of a vnn'xing tube, avmantle supported at -the lower end of the mixing tube, an inverted bell shaped detleetor carried by the mixing tube over the, mantle and having its upper edge flared outwardly, downwardly extending arms projecting from the said flared edge of the detlector, a globe supporting ring carried by the arms, and a globe surrounding the mantle and supported by the ring. l
2. In a gas burner7 the combination of a mixing tube, a mantle supported at the lower end of the mixing tube, an inverted bell shaped detiector supported by the mix- Y ing tubefover the mantle and having its upper edge flared outwardly, downwardly extending arms projecting from the said iared edge of the delector, lugs projecting from the arms, a globe supporting ring engaged by the lugs, an, exterior ring supported by the arms, and a globe surrounding the Inantle and supported by the globe supporting ring.
ln a burner, the combination of a mixing tube, a mantle supported at the lower end of the mixing tube, an inverted bell shaped deliector carried by the mixing tube over the mantle, the upper edge of the defleetor being flared outwardly and having lips cut therefrom to prevent the accumulation oi"v heat thereunder, arms extending downwardly from the flared upper end of the dellector, a globe supporting ring carried by the said arms, and a globe inclosing the mantle and supported by the globe supportmgl-lng.
