SAD-IRON.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed January 27, 1911. Serial No. 605,065.

To all whom it may concern:

Be it known that we, HARRY C. NEEL, a resident of Dravosburg, in the county of Allegheny and State of Pennsylvania, and JOHN B. HATFIELD, a resident of Alexandria, in the county of Huntingdon, in said State of Pennsylvania, have invented a new and useful Improvementin Sad-Irons; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to sad irons, and has special reference to such irons known as self heating irons which are adapted to generate the heat desired for the same when in use.

The object of our invention is to provide a cheap, simple and eff cient metallic sad iron, which will enable the heat from gener ating fluid carried thereby, such as alcohol, to be regulated to give the desired heat to the iron when or when not in use, will assist in preventing such fluid from being forced or ejected into the auxiliary heat generator from the storage or generator tank carrying such fluid for heating, will provide for such auxiliary generator being in the proper position for operating, as well as the starting dish to be in proper position with relation to the burner employed, and will enable all the parts of the iron to be so arranged as to give the best results in this class of irons, while at the same time such arrangement will permit the parts of the iron to be easy of access for handling in the operation and for their removal in case of repairs or any other purpose.

To these ends our invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which our invention appertains to construct and use our improved sad iron, we will describe the same more fully, referring to the accompanying drawing, in which Figure 1 is a longitudinal central section of our improved sad iron. Fig. 2 is a crosssection of the same on the line 22, Fig. 1, looking in the direction of the arrows. Fig. 3 is a rear end view of the same. Fig. 4 is a perspective view of one of the tank disks.

tion.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing, 1 represents the base or body of our improved sad iron, which is hollow to form the heating or combustion chamber 2 therein, and is provided with a series of lugs or projections 3 in such chamber and extending up from the bottom 4 of said body. The sides 5 of the body 1 have a series of vent holes 6 at the upper edges of the same, and extending over the chamber 2 and upper edges of said sides and front end 1 on said body is the cover plate or lid 7, which, is slidably movable over the lid 7 is the heat conducting block or regulator 9, which is preferably square in cross-section and slidably mounted on said lid by means of screw-pins 10 engaging with the same and extending down from the bottom of said regulator so as to pass through slots 11 in said lid and be held therein by means of heads 12 at the lower ends of said pins. Above the regulator 9 is the auxiliary vapor generator 13, which is in the form of a hollow tube, preferably square in crosssection and of substantially the same crosssectional area as said regulator. This generator 13 is provided with a screw cap 11 at its front end, and adjacent to said end and leading from a nipple 13 on the top of said generator is the outlet tube 15, which extends up vertically therefrom and opens into the generating and storage tank 16 for the operating fluid above said generator by its forwardly curved upper end 15, while such generator is held in position at such front end of the same by such nipple passing through the bottom of said tank and engaging with the same by a threaded connec The tank 16 is circular in cross-section and is provided with the caps 17 and 17 at each end of the same, to which it is connected in an air and gas tight manner, preferably by a welded joint, the front cap 17 being provided with a filling tube 18 extending into said tank and closed by the usual threaded plug 19. The front supporting plate 20 extends around the tank 16 and is secured at its lower end to the front end 1 of the body 1 by the screws 20,while a rear supporting plate 21 is adapted to be connected to the rear cap 17 by a screw 21 centrally of the same and to the base or bottom 4 by the screws 21.

Within the chamber 2 is the burner 22,

which is preferably circular in cross-section Fitting against the rear plate 21 is the' vertical carbureter 26, which is detachably connected to the lower end of said plate by means of the screws 26, which also pass into the lugs 23 on the burner 22 to support said burner at its rear end, and such carbureter is provided with a valve chamber 27 at its upper end having a passageway 28 leading therefrom into the generator 13 through a nipple 29 on said carbureter, to which said generator is removably connected by the threaded connection 29 to support the rear end of the same. A carbureter chamber 30 is formed in the carbu reter 26 below the chamber 27, which opens to the atmosphere by the air opening 31 at the upper end of the said carbureter chamber, and has an opening 32 adjacent to the bottom of the same for leading into the burner 22. A screw-plug 33 fits within the lower end or bottom of the chamber 30 to close the same, and a needle valve 34 fits within an opening 34 in the bottom of the chamber 27 and above the chamber 30 and air opening 31 therein, which valve is pro vided with the threaded vertical rod 35 thereon for engaging with the wall 35 of the carbureter 26 above the chamber 27, and is provided with a handle or wheel 36 at its upper end for raising and lowering said valve in the feeding of the gas from the generator 13 to the chamber 30. v

A handle 37 is secured between the upper ends of the supports 20 and 21 by the bolt 38 passing through the same.

Within the tank 16 are a series of circular portions or disks 40 which are set in a ver tical line so as to divide said tank into a series of compartments 41, which disks are secured to the wall of said tank in any suitable manner through the flanges 40 thereon, while the topsand bottoms of said disks are provided with holes 42 and 42 respectively therein to permit the flow of the fluid through the same from one of the compart- 1nents41 to the other, andlat the same time such disks will assist to prevent any entrance ,of the fluid into the outlet pipe 15 through its curved end 15 in the backward and forward movement of the iron when in use.

The operation of our improved sad iron is as followsThe iron is stood on its end,

7 and with the plug 19 removed from the filling-tube 18, the fluid, such as alcohol, is

poured through such tube into the tank 16, to fill such tank to the inner end of said tube, after which such plug is replaced in such tube and the iron is set upon its base or bottom 4 for operating. With the lid 7 removed from over the chamber 2 on its pivot 8, the priming or starting dishes 25 in said chamber are filled with the fluid and ignited, whereupon the fluid in the tank 16 is heated by the flame from said dishes, so that the vapor from such fluid as gener ated will pass down through the tube 15 and into the auxiliary generator 13, where such vapor is also heated by said flame, and after the fluid in said dishes has been exhausted, such lid is returned to position over said chamber. The tank 16 being now heated will continue to emit vapor through the tube 15 to the generator 13, which vapor then passes from said generator through the passageway 23 and valve opening 34 into the carbureting chamber 30, where it mixes with the air entering the opening 31 and such mixture will then pass through the opening 32 into the burner 22. After the mixture has entered the burner 22 it is ignited by a flame and such flame therefrom is directed into the chamber 2 and downward against the base or bot-tom 4 of the iron through the perforations 22 in said burner. The amount of vapor entering the chamber 30 from the generator 13 is regulated by the needle valve 34, which extends into the opening 34 leading to said chamber and is operated by the handle 36 connected to the rod 35 of said valve, while the amount of heat required or necessary to the tank in the proper operation of the iron is regulated 1 11 of said lid, as shown by the full and dotted lines in Fig. 2. This regulation is effected by the fact that when the regulator 9 is in a position such as shown by full lines in Fig. 2 there will be practically a direct metal path from the lid 7 to the generator 13 for conducting the heat to such generator, while if the regulator is in the position shown by dotted lines in said figure, there willbe a free circulation of atmospheric air between such lid and generator and thus less heat will be conducted to such generator.

Various modifications and changes in the design and operation of our improved sad iron may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

It will thus be seen that our improved sad iron will be so arranged that all parts of the same can be removed or separated for the purpose of the iron being kept clean at all times, while the construction of the iron will also enable any of the fluid in the tank entering the vapor supply tube to the auxiliary generator to be vaporized, and the heat which the fluid in the storage tank receives will be thoroughly regulated at all times, so that the vaporization of the fluid contained in such tank will be completely controlled by the moving of the regulator from side to side, as may be desired and the overheating of the fluid in the tank prevented thereby. The construction of the storage tank will also overcome all liability of the usual wave motion of the fluid therein from one end to the other in the reciprocating operation of the iron, in which motion the fluid was liable to enter the vapor supply pipe, and will enable such wave motion to be broken up into a series of wave motions within each of the compartments.
