4 Claims. (01. 21938) This invention relates to improvements in a bodiment of the herein disclosed invention may portable fabric steamer. be made as eome'withinthe scope of the claims. One of the objects of the present invention is Figure l is a vertical sectional view through the provision of a portable fabric steamer includthe body of the device, with parts thereof illus- 5 ing a boiler electrically heated and provided trated in elevation; therein with a steam conduit having one end Figure 2 is a bottom plan view, with parts thereof leading out through the top of the boilthereof broken away. er for projecting steam onto fabrics, such as In carrying out our invention, the device ins plush, velvet, and the like, to bring thenap in cludes a cylindrical body 1 which forms the boil..-

Another object of the present invention is the While the edges are disposed at right angles, as provision of a device of the above character, shown at 3, and then bent'upwardly around the wherein steam will be highly vaporized and prolower end of the body 1, as shown at 4, and then vide a fine spray of steam to be directed onto extended laterally and provided with apertures fabrics, such as velvet, plush, and the like, for to provide a securing flange.

I. cludes a tubular conduit leading from a point At theupper end of the boiler .1, we provide adjacent the top of the boiler down to close a sleeve 16 internally threaded to receive the proximity to the heater, and then coiled with headed plug Which'has bore 13 leading m the second end projecting out through the top the inner end thereof, and which communicates 35 of the boiler for the discharge of the steam, with an aperture in the outer end of the 'plug. whereby the steam is superheated by the hot Slidably mountedwithin the bore 18 is :a'. pin water as it passes through the tubular con- 19 having stop nuts'20, on the inner end, and duit. a head 21 on the'outer end. Mounted upon A still further object of the present invention the pin 19 and disposed between the inner end is the provision of a steamer of the above charof the bore 18 and the nuts 20,'*is acoilsp'ring acter, wherein the inlet of the steam conduit is 22 which normally urges the head 21 towards a positioned at the opposite side of the boiler from seated position. The pin 19 carries a washer the outlet, so that when the device is tilted 'for 23 positioned beneath the head'21, so as to form directing the steam onto the fabrics, the water a tight closure for the aperture in the end of a 5 within the boiler will not enter the conduit, the plug ,17. The plug. 17 is provided with latwhereby the boiler may be disposed at various erally disposed ears 24 forming thumb pieces angles without any water entering the inlet end whereby the same may be screwed into the sleeve of the conduit. 16,. or removed therefrom.

With the above and other objects in view, The movable pin 19 forms a safety valve, for the 0 which will appear as the description proceeds, body of the boiler whereby, when the steam presthe invention resides in the novel construction, sure within the boiler reaches a predetermined combination and arrangement of parts substanpressure, the head 21 will be unseated, permitting tially as hereinafter described and more particuthe steam to pass upwardly through the bore 18 larly defined by the appended claims, it being and out through the aperture in the outer end of understood that such changes in the precise emthe plug. In order to determine the water level 1 within the boiler body 1, lateral pipe's 25 and 25' are connected up with the body 1 at suitable points as indicated in Figure 1, and these pipes are connected by means of a gage glass 26,

'One of the main features of our invention is the arrangement of the steam conduit 27, wherein one end of the tube opens into the boiler adjacent the upper end thereof, as indicated at 2-8. The

tube then extends downwardly to a point adjacent the heating element 12. The tube is then coiled,

as shown at 29, and passes out through the top of the boiler upon the side thereof opposite the inlet end 28 and extends laterallyat an angle relative to the body ofv the boiler to form a discharge nozzle 30. It will be apbelentfrorn this arrangement that when the boiler i is tilted to a guide the discharge nozzle 30 over the surface of the fabrics, the water within the boiler will not enter the inlet end 28 of the tube. However, by causing the steam to travel downwardly and then around through the coil 29, the steam, through the medium of the water within the boiler will be superheated and will be highly vaporized by the time it passes out through the nozzle 30, resulting in a fine spray of steam beingdischarged onto the fabrics. t v

One side of the boiler l is provided with internallythreaded reinforced portionsgl to which theframe 32 for the handle 33 is connected, by-

means of thescrewbolts 34.- Suitable insulating washers 35 can be mounted upon the shanksof the bolts 34an d positioned between the frame 32 and the outer faces of the reinforced portions 31,

From the above description taken in connection with the accompanying drawing, it will be readily apparent that we have provided a very simple and inexpensive device which will prove very effi" cient for the purpose intended, generating, by

electrically heating, a very fine spray of steam,

which is superheated by passing the same through the hotwater in the boiler. This device has been found to be'very useful in steaming fabrics, such as plush, velvets, and the like, for raisingthe nap thereon, which is usually pressed down through. the folding of the goods.

Various types. of bottom members can be used for supporting a device upon any surface, but it is preferred to have a bottom member which is inserted in, spaced relation with the surface, so

that, the heat from the electric heating element will not injure a highly polished surface.

I Various-types of heating elements can be used, butit is preferredto provide aheating element which canbe installed within an enclosed chamber in the bottom of the boiler, so that the water Within the boiler will be inwardly heated and maintained at a boilingpoint in order to develop It suflicient steam for the purpose intended' will alsoibe noted that when the steam reaches a predetermined pressure it will pass out'through the safety valve atthe top'of the boiler.

While we have shown and described the preferred embodiment of our invention, it will be apparent from the foregoing that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claims. v I

. We claim:

A device of the character described including a cylindrical body, a heating element arranged in the bottom thereof, a steam conduit within the body having its outlet end adjacent the top of'the body and at one side thereof, said conduit extending downwardly to a point adjacent the bottom and coiled with the coils extending upwardly, the outlet end ofsaid conduit extending through the top of the body at the'side thereof opposite the inlet, a safety valve 'removably positioned in the .top of the body and a removable handle attached to theside of the body and arranged upon the opposite sides of the outlet of the steam conduit.

4. A portable device for steaming fabrics. cornprising a boiler body,'an electrical heating element disposed in the lower end of the body, a steam conduit pipe disposed in the boiler body havingits inlet positioned adjacent to the. top of the boiler above the water-level of the boiler and at one side of the longitudinal axis of the boiler, and a laterally extending outlet formed on the steam conduit extending out through the top of the boiler on the side of the boiler opposite to the inlet whereby upon the tilting of the boiler toward said outlet, the water. will gravitate away
