LAUNDRY-IRON.

Specification of Letters Patent.

Application filed December 2, 1908.

Patented Sept. 13, 1910. Serial No. 465,639.

To all whom 'it may concern: Be it known that I, EARLE R. SMITH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Laundry-Irons, of which the following is a specication.

The invention relates to a laundry iron which is adapted to the use of liquid fuel carried by .the iron itself.

The invention consists mainly in the provision of an efficient form of burner and generator for :the liquid fuel, and in the combination of these parts with the main body of the iron. In this regard it has been the object to so construct the parts that they may be easily taken apart and reassembled to clean or start the iron.

In the construction of the burner proper it has been the object to provide a simple construction which is durable under the most adverse conditions. For this purpose the generating coils have been placed inside the mixing chamber of the burner where they are completely incased. The fiame plays upon the under side of the mixing chamber and rises around it, thus keeping it hot for the vaporization of the liquid.

In the accompanying drawings :-Figure l is a longitudinal section of the iron. Fig. 2 a sectional plan view taken on line Q-2 of Fig. 1. F ig. 3 is an enlarged sectional detail of the burner valve. Fig 4 is an enlarged sectional detail of the reservoir valve. Fig. 5 is an enlarged detail view of the connecting means between the portions of the vaporizing pipe.

In ythe drawings 5 designates the body of the iron. In general it is boat sha ed with an open top over which cover 6 is adapted to fit and has an aperture 7 in its rear end through which the burner projects. Top 6 is composed of a base 8 of metal having a heat insulating layer 9 of asbestos and a metal facing l0. At the rear end of the cover a vertical arm ll supports a handle 12 composed of some `non-conducting material to protect the hand of the user. The

front end of the base of the cover is beveled as at 13 and the projection thus formed enters the overhauging part 14 of the upper front part of the body of the iron. At the rear end of the cover a catch l5 is secured to arm ll and two projections 16 on its lower end are adapted to enter into apertures 17 on the rear end of the body. A button 18 on the stem 19 is placed so as to be operated by the finger or thumb of the operator to release the spring catch from engagement with the body of the iron so that the cover may be easily removed.

Located in the lower part of the interior of the iron 4body is a removable mixing chamber 20 which is fiat and boat shaped similarly to the body. This mixing chamber is formed with a perforated bottom 2l, the mixed vapors escaping through this bottom and burning below and around the chamber. This location of the `fla-me keeps the mixing chamber hot at all times and warms the vapors prej'iaratory to their combustion. The bottom ofthe body of the iron is pro vided with a number of upwardly projecting pins or lugs 255 through which the iiame plays so that a large area is exposed to the flame for absorbing the heat and transmitting it to the iron body. These lugs being on the bottom it is seen that they transmit the heat directly to the lower surface of the iron where it is desired.

Coiled inside the mixing chamber is a vaporizing `pipe 22 connected at one end to a liquid tank Q3, the pipe and member 32 forming the support for the tank. After traversing the mixing chamber several times to provide ample opportunity for the vaporzation of the liquid the pipe end 24 is connected to a duct 25 in member 2G, the duct leading to needle valve 27 through which the vapors are discharged into the mixing tube Q8. Mixing tube 2S leads over the mixing chamber and discharges into it at 29 in the center of its upper wall. On passing into the mixing chamber the vapors are distributed over the bottom plate and emerge through the perforations therein.

For the cleaning of the vaporiziug system pipe 92 is made in two sections joined together by a fitting 40. This fitting is constructed so that one of the pipe sections may tit into it and the other section over it, so that, with the vapor passing in the direction indicated by the arrow, there is no opportunity for its escape at the joints. At thel end of the pipe, where it enters member 2(5, a plug 2G is provided so that the pipc may be cleaned by the removal of the plug.

The forward end of the mixing chamber is provided with an extension 30 fitting under a shoulder 3l on the body of the iron and preventing the upward movement of the front end of the mixing chamber. The mixing chamber is prevented from moving rearwardly out of the body by the provision of a stop member 32 having shoulders 33 engaging with the sides of aperture 7. The co-ver is provided with a lug 34 bearing against the top of member 32 and also against the rear end of the body,- the cover being thus prevented from moving rearwardly and disengaging itself from the body.

In Fig. 3 I have. illustrated a form of valve which is especially useful in my iron. Valve stem 40 enters member 26 through stufling box 48. A removable valve seat 42 is screwed into the member and is provided with the usual valve aperture which is closed by pin 4l on stem 40. The stem is in screw threaded engagement with the member so that its rotation operates the valve in the usual manner.

In Fig. 4 is illustrated the reservoir valvev used for filling the reservoir with air under pressure above the liquid. Filling plug 43 on the top of the reservoir is provided with a small plug 44 having a bore 45 therethrough. The top of the bore is enlarged for engagement by a hollow key of the general character used for the inflation of footballs and the plug is turned by the tight fitting of the key in this bore. Under the plug a washer 46 is provided to prevent leakage and a port 47 leads from the side of the plug bore to the bottom of plug 43 where it connects with the interior of the reservoir. By turning'plug 44 up so that the air may pass from bore 45 to port 47 the reservoir may be charged.

f I-Iaving described my invention, what I claim is l. In al laundry iron, a body portion, a removable liquid fuel burner attached to the body portion, the burner comprising a flat mixing chamber vhaving an opening for combustion on its lower side, a vaporizing coil for the liquid fuel laid flatly within the mixing chamber, and means for injecting the generated vapor with air into the mixing chamber.

2. In a. laundry iron, a body portion, a removable liquid fuel burner attached tothe body portion, the burner comprising a flat mixing chamber having combustion openings on its lower side, a vaporizing coil for the liquid fuel laid flatly within the mixing chamber, a liquid fuel reservoir connected to one end of the vaporizing coil, and means connected to the other end of the coil to inject the generated vapor into the mixing chamber.
