SAID-IRON.
Specification of Letters Patent.
Patented June 15, 1915.
Application filed February 20, 1915. Serial No. 9,483.
To all 1071 0m it may concern:
Be it known that I, GEORGE T. BOSENGREN, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sad-Irons, of which the following is a full, clear, and exact description.
The invention relates to sad irons, and more particularly to that class of sad irons which comprise a burner for liquid fuel, such as kerosene or gasolene.
In practice, it has been found that some sad irons provided with kerosene burners did not operate satisfactorily because elficient provision was not made for thoroughly vaporizing the liquid-fuel before its delivery into the burner tube, which resulted in insufficient vaporization and preheating, and at times the liquid would be discharged from the generating tube. 7
One object of the invention is to provide an etficient device whereby kerosene, as well as gasolene. will be efiectively preheated and vaporized for combustion in the burner-tube, and this object is attained by surrounding the vaporizing tube with a jacket of high conductivity, such as copper, which will distribute the heat to all portions of the vaporizing tube and thoroughly heat it to effect vaporization of the liquid therein, the tube being formed of a harder metal, such as brass, which will not scale from the heat and thus cause a deposit or obstruction in the generator.
W'hen kerosene is used as a fuel, the nozzle of the generator is provided with a very minute opening which occasionally, and sometimes frequently becomes clogged. In the devices heretofore used, the interruption of the fuel, caused by insertion of a cleaning needle, usually disposed on the end of the valve for controlling the supply of liquid fuel, would cause the generator to cool so rapidly that preheating of the generator was necessary every time that the nozzle was cleaned.
Another object of the present invention is to provide a sad iron with an improved generator which will remain sufficiently hot for effective vaporization and for a sufficient period to permit the cleaning needle to be operated through the nozzle without necessitating preheating of the generator after each cleaning operation.
The invention further designs to provide zfin limproved sad iron adapted for liquid The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the c0nclusion hereof.
In the drawings: Figure 1 is a perspective of a sad iron, embodying the invention. Fig. 2 is a perspective of the generator and burner. Fig. 3 is an enlarged section of the generator and burner.
The sad iron comprises a body 10 and a cover 11 which is removably connected thereto in any suitable manner. The body 10 is hollow and comprises a bottom 12, side 14 having openings 15 therein and a rear wall 16. A handle 17 is secured to the upper member of a resilient U-shaped strip or bar 18 which has its lower member 19 secured to the cover 11. A strip of insulation 20 is interposed between the cover and member 19 to prevent heat conduction t0 the handle.
The improved sad iron is particularly adapted to be heated by liquid fuel and a reservoir 21 is provided for containing the fuel. The reservoir 21 may be of usual construction, and is adapted to hold the liquid under pressure. Member 19 of the resilient connection between the handle and the cover is extended rearwardlv and laterally to form a supporting-arm 22 for the reservoir. The latter is secured to a forwardly turned terminal 23 on the rear end of arm 22. The
reservoir is secured to terminal 23 bv a nut 24 and a reversely curved pipe 25 leading from the bottom of the reservoir extends through an elongated slot 26 formed in a member 22. This supporting-arm and itsterminal 23 form a somewhat yielding or resilient support so that the reservoir 21, if it strikes an obstruction. as sometimes'occurs in use, will not be broken, the yielding support serving to cushion any blow against the reservoir. Pipe 25 conducts the liquid fuel to an upwardly extending nipple 27 of a valve-casing 28, to which it is connected by a suitable union coupling 29. Nipple 27 extends through a slot 30 at the rear end of cover 11, and casing 28, ofwhich the nipple 27 is a part, is secured to the cover by a nut 31, cooperating with a shoulder 32 to clamp the casing on the cover.
A generator-tube 33 has one of its ends screw-threaded to the casing 28. A valveseat 34.- for a valve 35 which controls the supply of liquid to the generator is formed in casing 28. Valve 35 is on the inner end of a stem 36 which is screw-threaded to a nipple 37 of casing 28 and is provided with a wheel 38 at its rear end whereby the valve may be manipulated.
In sad-irons, it is particularly desirable to make effective provision against leakage of the liquid-fuel, particularly if kerosene is used, and for this purpose, a double packing is provided around valve-stem 36. One packing 39 is held in a gland 40 which is screw-threaded to nipple 3'7 and an additional packing 41 is held in the outer end of the gland 40 by a follower 42 which is screw-threaded into the outer endof the gland. By adjusting the gland 40, the packing 39 may be tightened and by adjusting the nut 42, the packing41 may be tightened around the stem 36. This packing-means is simple in construction and provides effectively against leakage of the liquid around the valve stem 36.
The generator-tube 33 is disposed beneath the cover 11 and in the body of the sad iron. A nozzle 44 is screwed into the discharge end of this tube and this nozzle is formed with a very small opening 45 through which the vapor passes to a mixer-pipe 46, which is secured in the cover by a screw 47. The cover 11 is depressed or recessed, as at 48, so that sufficient air from the outside for combustion will pass into and be mixed with the vapor in pipe 46. Pipe 46 connects with the burner-pipe 49 which is provided with cross-slits 50 of gradually increasing length, to discharge the vaporized fuel at the point of consumption adjacent the base 12 of the iron. The rear end of burner pipe 49 is closed by a plug 49 The mixer and burnerpipe are formed of a U-shaped tube. A subburner 51 is secured to the rear end of burner-pipe 49 to heat the generator. This sub-burner 51 comprises a nipple 52 which is secured in the burner 49 and its top wall is provided with small holes 53 and a longitudinal slit 54 which are disposed below the generator to provide a flame under the generator, which will thoroughly heat it to cause vaporization of the liquid fuel. In practice, it has been found that when the burner 51 is provided with a longitudinal slit and these holes, the flame will burn evenly and regularly, so that the generator will be constantly kept at a high temperature for effective generation.
The ends of the mixer 46 and the nozzle 44 are correlatively disposed to effect a proper mixture of air and vapor when either kerosene or gasolene is used. In practice, it has been found to be desirable to provide a sad iron that may be used with either of these fuels.
The generator-tube 33 is usually formed of brass and a tubular copper jacket surgree by heat from the burner '51 and, by I reason of its high conductivity, it conducts and distributes the heat to all portions of the generator tube 33 to which the liquid fuel is delivered. In practice, it has been found that when this copper jacket is used around a brass generator tube, the latter will be kept so hot that the fuel will not condense on the needle 61 in the tube.
A groove 40 is formed in the pa cking gland 40 to minimize conduction between the two portions of the glands in which the packings are held.
Needle 61 is provided with a point 65 which is adapted to enter the small jet-hole 45 in the nozzle 44. This point is adapted to clean out hole 45 whenever it becomes clogged, as is frequently necessary when kerosene is used for fuel. This point can be operated to clean out said hole by turning the wheel 38 quickly, to force the point 7 through the hole and then turning said wheel to withdraw the point from the nozzle. In practice, it has been found that when the generator is constructed as described, it will be heated to such a high I degree that kerosene will not condense on the needle during the cleaning operation, and so that when thepoint is operated quickly, the hole 45 can be cleaned out without necessitating preheating of the generator before the burner will operate. In starting the use of the iron, after ithas become cold,
use of keroseneas a fuel and which may also be used for gasolene. The generatoris constructed so that it will thoroughly heat and vaporize liquid fuel, particularly kerosene. Provision is made for keeping the generator hot so that there will be no difiiculty in keeping the iron constantly heated. The use of a fiat U-shaped strip for supporting the reservoir simplifies the construction of the device and provides a yielding support which avoids breakage of the reservoir. The sub-burner for the generator is particularly adapted to provide a small regular flame for heating the generator.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
