ARTHUR G. SAILER, MASSILLON, OHIO, ASSIGNOR OF ONE-HALF TO LA'TRENCE P. MELVIN, OF MASSILLON, OHIO.

GAS-HEATED SAD-IRON.

Leanser.

` Massillon, in the county of Stark and State of Ohio, have invented a new and useful Gras-Heated Sad-fron, of which the following is a specification.

ln gas-heated sad-irons it is a well knownfact that there is little di'liiculty in obtaining the necessary heat in the iron itself. Some of the difficulty however is the regulation or control of the heat in the iron, provision for proper distribution, the consumption of the minimum amount of gas.

The present invention relates to improvements in the construction of sad-irons of the class mentioned, the objects of the present improvement being to more perfectly distribute and control the heat in the iron, to improve combustion and at the same time provide a pilot light.

These objects together with other objectsv readily apparent to those skilled in the art are attained by the construction and arrangement illustrated in the accompanying drawings, in which- Figure l is a longitudinal vertical section on the median line illustrating` an iron embodying my improvements. Fig. 2 is a transverse section on line 2 2, Fig. l. Fig. 3 is a detached perspective view of the burner. Fig. 4 is a rear end view of the sad-iron showing portions of the main and pilot gas pipes. Fig. 5 is a view showing a portion of the sad-iron illustrating the valve connection for the pilot gas pipe and illustrating the position of the valves with reference to each other. Fig. 6 is a horizontal section showing the main supply passage open and the pilot passage closed. Fig. 7

is a similar view showing the main supply y pipe partially closed and the pilot passage partially open.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

n the accompanying drawings, 1 represents the hollow body of the iron which is open at its top, the cover-plate 2 being adapted to properly close the top of the hollow body. To the cover-plate 2 is attached in the usual manner the handle 3. In the drawings l have illustrated the handle attached by suitable lug bolts 4 but it is immaterial as to the method of attaching the Specification of Letters Patent.

handle. Vithin the hollow body lis located the burner 5, which burner consists of tapered pipe, the chamber of which is illustrated in cross section in Fig. 2. For the purpose of providing a chamber of sufficient size at the gas intake end of the hollow body l Vthe intake end of the burner is provided 'with the upwardly extending portion 6. Said upwardly extending portion also serves to guide or move the gas for the pilot light downward or toward the bottom of the hollow body l.

For the purpose of supporting the burnery its sides ,are provided with the integral blades or flanges 7, which blades or flanges are preferably located in the same horizontal plane. Below the blades or flanges 7 are located a series of vertical plates or partitions 8, which plates or partitions are for the purpose, first, of supporting and holding the burner an d removingthe strain from its attached end, and second, the vertical plates or partitions 8 produce separate chambers or pockets whereby the flame emanating `from the burner is better confined and a more even heat throughout the entire length of the sad iron maintained. By tapering the burner from its intake end toward the rear end, the size of the chamber is gradually reduced by which arrangement the gas is more evenly distributed, thereby producing a more uniform flame throughout the entire length of the burnerand consequently, a more uniform heat through the entire length of the sad iron proper. The bottom or underside of' the burner is provided with a series of transverse slits 9, which transverse slits are located on the underside of the burner and directly over the various chambers between the vertical partitions 8.

For the purpose of allowing the flame `to `becontinuous from. end to end at that portion of the burner provided with the `slits 9, the tops of the partitions 8 are cut out or recessed so as to provide a continuous chamber directly below the plates or flanges 7, but at the same time partially separating the lower portion of the flame and confining the same in the di'erent chambers.

For the purpose of aiding combustion the side walls of the hollow body 1 are provided with the air intake apertures l0. For the purpose of providing means forconnecting the burner 5 to the hollow body l, the flanges ll are provided and are connected to the body in the usual manner by bolts or their equivalents. F or the purpose of providing a pilot light the pilot suppl-y pipe 12 is provided which is connected to the head 13. The burner 5 is provided with the passage 1%, which registers with the passage 1G formed in the head 13. "Io the head 13 is attached the main supply pipe 17 in any convenient and well known manner, which supply pipe leads to any source of supply.

The passage 16 formed in the head 13 is curved so as to bring the intake opening 1n a true vertical position, by which arrangement the supply of fuel is free to pass into the burner without first being shunted toward the bottom of the burner. By this arrangement the fuel is better distributed and a more even flame is produced, owing to the taper of the top of the burner, which tapered top forces the fuel toward the bottom of the burner as it moves along toward the inner end of said burner. The lower inclined portion at the intake end of the burner has a. tendency to prevent the gas from being forced through the adjacent slits 9 to a greater extent than the remaining or more remote slits, thereby producing an even and uniform flame, throughout the entire length of the burner,

Then it is desired to heat the sadiron proper the

valves

18 and 19 are both opened and gas supplied to the burner 5. But at this time the supply of gas is cut off from the pilot pipe 12. The valve 18 is an ordinary needle valve and is for the purpose of regulating the amount of gas to be supplied tok the main burner. When it is desired to extinguish the main burner the valve 19 is moved so as to close the main passage 19a and open the pilot supply passage 2Oa and supply fuel to the pilot tube 12, the action being such that the supply of fuel to the pilot pipe 12 will be such that the pilot light will be ignited before the main light has been extinguished, thereby lighting the pilot light and extinguishing the burner. By the reverse action of the valve 19 the fuel supply is cut off' to the pilot light, but supplied to the main burner, the main burner being started or ignited from the pilot light.

It will be understood that by tapering the top portion of the burner and locating said tapered portion above the slits 9 the fuel will strike the bottom of the burner at an angle throughout the entire length of the burner thereby supplying an equal amount of fuel to each and all of the slits by means of which a uniform llame and uniform heat is maintained.

For the purpose of better feeding fuel to all of the slits the bottom of the burner is formed straight, said straight bottom being located directly below the tapered top portion of the burnert It will also be understood that by providing the vertical parti tions 8 and spacing said partitions the ame emanating from the burner 5 will be confined in the chambers between the partitions and the burner support flanges, thereby spreading the fla-me toward the sides of the hollow body, by which arrangement a uniform heat is produced upon the entire surface of the bottom.

F or the purpose of supplying a mixture of air with the gas which supplies the pilot light the air intake 12l is provided and is so located that the air will be taken into the passage leading to the lower portion or chamber of the hollow body 1. For the purpose of supplying fuel for the pilot light the passage 13CL is provided which passage communicates with the passage 14n formed in the head 13.
