To all 'whom it may concern Be it known that l, EARLn R. Ponnann, a citizen of the United States, residlng at Los Angeles, in the county of Los Angeles and State ot California, have invented certain new and useful Improvements 1n Sadirons, of which the followmg is a speeliication.

This invention relates to improvements in sad irons, and particularly to that class of 'irons which are Self-heated, and whlch are capable of generating steam for moistening the goods which are to be pressed by the iron. j

lt is an object of the invention to p rovide an iron of the class mentioned, havlng a base portion provided with a separable steam distributing part adapted to deliver steam to the goods to be pressed, the iron also having a steam generator, which 1s connected with said steam distributing portion.

lt is also an object of the invention to i provide a sad iron with a flash boiler adapted to generate steam as fast as water is delivered into the saine, the body portion of the iron being arranged to constitute a heating jacket for enclosing the said bo1lera heating space being arranged to extend en tirely around the boiler within the lron, the iron also having a heating member mounted within the said space. j

lt is a further object of the invention to provide a sad iron having a base with a marginal edge formed thereon, the sald base having a nose piece formed with steam passages therein, and having steam outlets, opening downwardly and laterally, the iron also having a steam generating boller for supplying steam to the, said nose piece, a jacket being arranged to surround and .apply heat to the boiler, the sald jacket Delng secured to the marginal edge of the base.

lt is still a further object of the invention to provide a steam pressing sad iron, having a flash boiler therein, and a valve controlled water supply to the said boiler, thel handle of the iron being provided with a rocking member under the control of the operator for controlling said valve member -in regulating the water supply.

With these and other objects in view, the invention comprises certain novel. constructions, combinations, and arrangements ot parts, as will be hereinafter more lully described and claimed.

The sad iron forming the subject matter. of the present invention is designed to af- :tord one which is capable of generating steam and of projecting the steam under the control of the operator, through as many layers of fabric as may be needed for facilisame.

rlhe details of the invention will now be more speciiically described, reference being had tothe accompanying drawing, in which 5 indicates a base, 6 a boiler or steam generator therein, and 7 a jacket or casing; The base of the iron is made with a smooth Hat bottom for almost its entire length, but is recessed and oH-set at the front end to receive a nose piece or member 8. The said nose piece or member 8 is provided with steam passages at 9 extending around near the outer edges ci the nose piece or member, and also with a transversely connecting passage 10. rlhe saidl nose piece or member 8 is provided `with discharge or jet openings l1 communicating with the passages 9 through the bottom thereof, and lateral orv inclined `"apertures or jet openings 12. ex-s tending toward the front corner edges of the nose piece :from said passages 9, whereby the show suHiciently to act as an indicator, of the -fact that` the steam is beingy generated and properly delivered through the nose piece of the iron.

The said nose Apiece is preferably cast of a single p-iece of metal, usually brass, in order that the jet openings may not be liable to corrosion and clogging, as would happen if iron were employed. The passages 9 and 10 are cored out through apertures formed in the walls of the nose piece, and normally closed by plug screws 13, as clearly shown in Fig. 5 of the drawing. The said nose piece is shaped tojfit the recessed or off-set portion of the front end of the base 5. Rismg from the central portion of 'the nose piece and so as to communicate with the transverse passage 10, is a hollow securing standard 14, as clearly shown in Fig. 1 of the drawing. This hollow stem passes through the shouldered part of the base, an aperture 15 being provided therefor, and also projects above the same, its upper end being only threaded exteriorly to receive a clamping nut 16 and a lock nut 17, by which the nose piece is directly secured to the said base. The upper end of the hollow standard 14 is also interiorly threaded to receive a short connecting pi e 18 by which it is connected with the boi er 6, and through which the steam generated in the boiler passes into the passa es of the nose piece.

around the same, and rises to a suitable height to give ample room for air inlet p-assages 20, which enter thebase just above the inner surface thereof, the said marginal edge or wall being preferably shouldered at 21, entirely around its rupper edge to receive the lower edge of the jacket 7, or casing proper of the iron. The iron is provided wlth any suitable heat producing device, a burner 22 being shown in the drawing.

The burner may be of any desired type, but is usually made of a tubular member extending from the end of the base 5 toa point near the off-set from end thereof. The portion 22 is provided with a series of jet openings 23 along the top thereof, and

"rows of jet openings 24: and 25 along the lower and lateral portions of the said burner, the flames from the said openings thus issuing from the burner alongt-hree substantially equidistant lines along the burner` whereby a proper' volume of heat is developed within the jacket and beneath the boiler, in such a way that the products of combustion may pass upwardly and entirely around the said boiler or steam generator. Outside the iron structure, the tubing forming the burner 22 is turned upwardly at 2 6, theV upper end thereof being provided with lateral openings 27 to form a mixing device, and having a controlling valve 28 adapted The base l 5 is provi ed with a marginal edge portion 19, which extends substantially e-ntirely to be connected with any suitable source of fuel supply. The base is also formed with a series of baffle projections 29, which extend upwardly from the Hoor of the base 5, so as to be opposite the air inlet openings 20. As shown in the drawing, the said projections may be triangular in cross section, with one of the angular edges presented toward each of the said openings 20.

The arrangement is such that the said baffles from the double function of the dividing and diffusing, the air rushing in through the openings 20, and preventing the jets of flame from the burner from passing out through said openings 20. The boiler 6 is a tubular member forming a steam generating retort, and it is found advantageous to forni the said boiler or generator with a substantially triangular erom section as clearly shown in Fig. 3 of the drawing. The triangular boiler with one of its sides around at the bottom, facilitates the maintenance of hot air spaces between the sides of the boiler, and the walls of the jacket 7. One end of the boiler is formed with lateral sleeves 3() through which securing bolts 31 are passed, the lower end of said screw bolts engaging in short standards 32, which project upwardly from the ioor of the base 5. The rear end of the boiler and generator is thus firmly fastened in position above the base. The forward end of the boiler is provided with a removable end iece 33, having a flange extending into a s iouldered recess 34 upon the body portion of the boiler 6. The said end piece 33 has a screw threaded opening 35 adapted to be screwed upon the upper threaded end of the connecting pipe 18, whereby'the front end of the boiler is securely fastened in place. A conical shaped screen 77 having a peripheral flange 3G, is clamped in place within the boiler between the body portion thereof, and the nose piece or front end portion 33.

The rear end of the boiler is also provided with an inclined -floor 37, adapted to receive the small amount of water, which is dropped into the boiler from time to time, and thus ensuring that the water be directed in the boiler, so as to be converted into steam. The water which is to be converted into steam in the boiler, is delivered into the said boiler through a valve carrying member 38, which has an elongated stein, having an exteriorly threaded portion adapted to be forced in a threaded opening 39 in the rear of the boiler. The lower end of the said stem is recessed at 40 and receives a ball check valve 41, which is held in place by a transverse pin 42, which extends across the said recess 40. The ball valve prevents the passage of steam from the boiler into the passage-way formed in the valve carrying member 38. rI `he said valve carrying member 38 projects through an opening'in. the jacket 7, and above the said iastate jacket it is enlargeglat 43 to receive a tumbler member 44, which is adapted to control a valve above the same, as will be hereinafter more fully described.

Rising from the upper surface of the boiler 6 are bosses 45, which have screw threaded recessestherein, and adapted to receive screw threaded bolts 46, which project through the yoke o-r frame 47 of the handle of the iron, and through the top of the jacket 7, for clamping the said handle and jacket to the said boiler 6. The jacket 7 is provided with a series of outlet or flue openings at 48, through which the products of combustion escape after heating the ackieft. The handle yoke 47 has a non-heat conducting handle 49, usually of wood fastened beh tween the upper ends of the said yoke, as shown in F ig. 1 of the drawing. The handle is' screwed to the yokel by suitable scre-ws 50..

The said handle is perforated lon itudinally, preferably in the lower part t ereof, for receiving a rocking member or shaft 51. The said shaft finds suitable bearings at 52 in the upper ends of the leg portions of the handle or yoke- 47. The shaft 51 projects from the forward end of the handle, and is turned longitudinally and somewhat upwardly with respect to the said forward'end of the handle, and carries a thumbpiece 53. Pressure upon the said handle will rock the shaft 51 in its bearings. At the rear end of the handle 49, a crank arm 54 is secured to the shaft 51, and is converted bly means of a link 55 with a valve operating pin or arm 56, which is connected with the tumbler member 44.

The water supply to the boiler or steam generator is thus under control of the operator of the iron, and water may be ad mitted to the said boiler by merely pressing upon the thumb or finger piece 53. A tumbler device in the water supply connection may be of any desired construction, but may as shown inthe drawing, be formed with a plate portion carried by end disc pieces 57, which fit snugly, though movably within the flanged portion 43 of the valve carrying member.

An operating stem 58 projects from the thumb member 44, through a packing gland 59, formed in the enlargement 43. A spring 6() mounted in an annular recess 61 formed in a screw cap 62, bears upon the opposite end of the tumbler from theshale/or stem 58. A short centering stud 63 extends through an aperture 64 in the said cap piece 63 to keep the tumbler member properlyV centered, in connection with the said stem 58. Above the tumbler member 44, the valve carrying member 38 is enlarged to receive a valve 65, the said valve may be of any measuring type if' desired, and engages a Vet seat 66 for controlling the passage of 4water through the mechanism to the boiler. A

downward projecting stem 67 engages the tumbler 44, so that when the tumbler is rotated, the 4valve may be lifted from its seat.r The valve also has an upward extension of its stem, which carries a second valve 68, which is adapted to engage a seat 69, formed in the coupling member 70. mounted upon the upper end of the valve carrying member 38. The coupling member 70 engages the screw threaded portion of' the water cut-off valve 71. A spring 72 is mounted within the coupling 70 and bears the upper end of the valve 68, and normally operates the valve device to seat the lower valve 66 thereof. The cut-off valve device 71 is adapted to be connected by a flexible ose pipe with a water supply of any desired kind, and the cut-off valve 28 is adapted to be connected by a flexible hose or pipe with a fuel or gas supply, the said flexible connections being of ample length to permit the use of the iron. rlhe rear end of the jacket 7 is provided with an opening 73 through which the burner may be readily lighted by the application of a match. The end piece 33 of the boiler 6 is preferably firmly held in place by connecting screw bolts 74, which pass through sleeves 75 upon the end piece 33, and screw into interiorly threaded sleeves 76, formed upon the adja cent end of the boiler 6.

1t will be apparent that the dierent portions of the iron, while so constructed that they may be readily taken apart or put together, are however, formed so that strong non-heating connections may be had. It will also be evident that many of the minor details of construction may be somewhatv altered within the spirit and scope of the invention, and that mechanical equivalents may be substituted for some-of the parts, without altering the spirit of the invention.

ln using the iron, the operator grasps the handle 49, the burner ,having| first been' lighted and permitted to burn for four or iive minutes. The iron will be hot enough ling valve and permita small quantityl'bf water to be dischargedvinto the generator. rThe water is immediately converted into steam, which will be forced through the passages of the nose piece and into the cloth or other fabrics treated, through the jet openings 11 and 12, since the steam cannot return through the valve mechanism, because of the ball check valve 41.

1t is not necessary to keep the thumb continually upon the lever device, it only being required to press upon it occassionally, 1n order to supply an ample quantity of steam for the ironing process. It 1s found that the steam forced out from a retort portion, such as that shown and described, will penetrate many thicknesses of clothing. The issuing of steam from the inclined or lateral open-A ings 12 permits ofthe seeing of the steam as it escapes, to indicate that the iron 1s working properly.

It will be noted that the lateral or d1- agonal jet openings l2 in the nose piece not only serve to make some of the steam visible, indicating that it is being properly supplied to the toe of the iron, but the steam at these jets also serves to moisten and affect the top or outer layer of goods to be pressed. VVhlle a triangular boiler has been shown in the drawing, it will be evident that boilers of other cross sectional shape will be very effective. Thus by rounding in a circular manner or similarly curving the t-op of the boiler, a very effective boiler will be produced. It will be further evident that in the place of the gas burner illustrated in the drawing, other kinds of burners may be used to advantage, as for instance, gasoline burners, or electric heater, all within the spirit and scope of the invention.
