PATENT LIAM C. COLEMAN, F WICHITA, KANSAS.
TER FOR GSOLINE STOVES.
Application filed November 9, 1923. Serial No. 673,797.
To all whom 'it may concern. y
Be it known that li, WILLIAM C. CoLEMAN,
a citizen of the United States, residing at Wichita, inthe county of Sedgwick and State of Kansas, have invented certain new and usefullimprovements in Preheaters for Gasoline Stoves; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, Iwhich form a part of this specification.
rlhis invention relates to hydrocarbon fuel burners and the primary object thereof is to provide a novel form of pre-heater for heating the generating chamber which transforms the liquid fuel into vapor or gas preparatory to admitting it into the burner chamber or chambers. The invention contemplates the provision of a slide which may be convenientl actuated to cause a baille to be interposed between the discharge end of the vaporizin chamber and the intake manifold for the urners so that the liquid initially passing through the vaporizing chamber before the vaporizing chamber is heated will be deflected into a pre-heating pan or cup undery the vaporizing chamber where it may be ignited to heat the vaporizing cham- `ber so as to heat the, li uid fuel to a vapor temperature, then the slide may be actuated to move the delector out of the path of the fuel issuing .from the vaporizing chamber permitting it to pass into the burner mani fold. rThe slide may be conveniently controlled from a point adjacent to the valve control and consists of certain novel embodiments which will be described` in detail hereinafter, references being had to the accompanying drawings, in which:
Fig. 1 is a perspective view of a burner constructed in accordance with my invention.
Fig. 2 is a detail perspective view of the slide and vaporizer cup. Fi 3 is a longitudinal sectional view showing the slide in cross section and the vaporizing cup in longitudinal section with the deflector in functional position, and
Yof the guide Fig. 4 is a sectional view through the slide and cup when the4 through port is in alignment'V with the vaporizing chamber.
eferring now to the drawin 1 designates the base of the urner manifold here shown as provided with two burner plates 2 and 3 provided with spaces to receive' the asified fuel so it can be ig.- njted through t le slits 4 and 4. rlhe memo0 bers 2 and S are conventional burner elements so their specific construction is immaterial.v The manifold 1 has a vertical inlet Y tube 5 connected to the rear wall 6 of a rcetangular slide guide 7 by a duct 8. The foro5 ward end of tube 8 is slightly flared to provcide a relatively wide mouth or inlet end so that gas and air may enter the duct 8 through dierent ports and become mixed to provide the proper air and gas mixture for the 7o Haine, therefore it will be seen that the duct 8 is a mixin chamber. In the front wall 9 is an opening 10 receiving the discharge end of the vaporlzing chamber or tube 11 which has one end supported by the 'w wall 9 and the other on a bracket 12 carried by the front burner element 2. The effective port area of the discharge end of the vaporizing chamber 11 is controlled by a valve on the end of the stem 13 in the usual manner 8o and the vaporizer tube 11 may be supplied with fluid through a pipe connection 14C communicating with a suitable source of supply, preferably under pressure. Slidable in the burner guide is a guide late 15. 85 The block constitutes a valve for va ving olf communication between the discharge end of the vaporizer tube 11 and the duct 8 and when the block or valve 15 functions as such,
a concavity or recess 16 of the vaporizing 90 pan or cup 17 will be brought into line with the discharge end of the vaporizing tube 11 so that the liquid fuel will be discharged against the concavit and be deflected into the longitudinally isposed pre-heater cup o5 in line with but below the vaporizing tube 11. The vaporizing cup 17 is boat-shaped and it preferably has a central opening 18 in its bottom surrounded by a vertlcal flange. 19, the central opening being for the purpose loo of permitting air to flow through the bottom of the cup to supply the necessary oxywith openings 22 and 23.
Y gen to support combustion. The plate is yshaft has a right angular extension to provide a handle 27 and the other end has an l upstandin projection 28 engaging a lug 29 in.I the sli e (see Fig. 2) so by turning the handle 27 the slide can be reciprocated'in its guide to cause the fuel passinefrom the vaporizer chamber or tube 11 to deflected in the cup! 17 or permittin it to pass into the duct 8 and then on to t e burners. The inlet openings to one of the burner elements 2 or 3 may be controlled by an individual valve on a stem 30, theotherburner being under the control of the valve on stem' 13.
`The slot 31 in front of guide 7 is lon enough to permit the necessary movement o in the cup and the flame therefrom w the cup 17 as it is carried' to and fro by the slide plate 15.
When the parts are assembled and it is desired to start the burner the handle 27 may be swung upward to bring the slide to the osition shown in Fig. 1 with the slide valvmg oif at duct 8 and presenting the` depression 16 or hood of the vaporizer cup 17` integral with slide 15 in line with the discharge end of the vaporizing tube 11, then the valve on end of stem 13 is slightly unseated so as to permit some of the llquid fuel to dischar e against the curved srface `of the de ectin recess -16 so it will ow into the cupf T e fuel can be ignited n ilhe'at the vaporizing tube 11 so that the liquid will be generated into gas. The observer can note the condition of the fuel issuing from the vaporizer tube when the valve on the end of stem 13 is slightly unseated and d when the proper vaporization is takin lace the operator can swing the handle 2 ownwardly so that the openin 23 will be in line with the' discharge end 0% the vaporlzing tube 11 and since the` slide has one back wall, it' is obvious that the fuel can pass into the duct 8 and into the manifold 1. Air for the gas will be furnished lthrough the end openin 31 communicating with the hollow portion of the slide as clearly shown in Fig. 1 so a proper mixture will be provided.
It will be apparent from the foregoing that the fluid issuing kfromthe vaporizing chamber or tube 11 may be used as a reheating medium for heating the vaporlzer and that, its deflection may be easily accom a slide,
plished by manipulating the slide as shown and as the temperature has been raised, the deector can be moved out of obstructing position and the channel can be used in the usual wa What f1 claim and desire to secure by Letters Patent is:
