SADIRON.

Application led April 10, 1924.

To r/.ZZ iff/1.0m t 11mg/ concern.'

Be it known that l, Mouais Roannais, a citizen of the llnited States, residing in Philadelphia, Pennsylvania, have invented certain linproveinents in Sadirons, of which the following is a specification.

Une object of niy invention is to provide an improved construction for use in conuection with sad irons of the type known as self heating irons where combustible fuel is placed in a hollow body portion of the iron; the invention including improved and novel actuating ineans` which can be easily and quickly moved to vary the amount of draft of air throiigh the iron.

nother objectis to so construct my invention that when applied to an iron, the latter can be manipulated and kept at a desired operating temperature and the draft regulation can be conveniently and accurately effected without waste of time.

These objects and other' advantageous ends which will be set forth hereinafter, l attain in the following manner, reference being had to the accompanying drawing, in which- Figure 1 a side elevation of a sad iron having iny invention thereon7 Figure 2 is a sectional top plan view taken on the line 2-2 of Figure 1,

Figure 3 is a sectional elevation taken on the line 3-3 of Figure 2, and

Figures l and 5 are top plan views of certain of the elements of iny invention.

leferring to the drawing, represents the hollow base or body portion of the iron for containing the combustible fuel. rlhis base is open at its top but is normally provided with a flat top or cover plate 11 which has a tongue 12 adapted to enter a notch Ji in thc front part of the base 10. A bolt or pin ldlextends through a hole in a lug 15, said lugl projects upwardly from the rear ol the base 10, the pin extending over the cover plate 11 and under the bot-toni 16 of the handle 1li. ln the arrangement as illustrated, parallel lugs 1T on the cover plate forin a groove or channel in which the pin 14 can slide, and the tongue 12 and pin 11 hold the cover plate to the base. In the drawing the handle 16 is shown riveted to the cover plate but can be secured thereto in any other suitable manner.

The front flat portion 18 of the cover plate 11 has a number of draft air holes 19, and the rear flat portion 20 of the cover Serial No. 705,516.

plate 11 has a number of draft air holes 21. A. shutter 22 is slidably mounted below the cover plate l1 and includes a shutter plate 23 and a projection or stein 2%, said stein having a row of teeth 25 which constitute a rack adapted toniesh with a toothed gear wheel 26. The gear wheel 26 is secured to an upright shaft or spindle 2T which rotatably fits within a hole in the cover plate 11 and extends upwardly through a hole in the bottoni 1G"y of the handle 16. A knob or finger piece 28 is secured to the top of the spindle 2T at a position spaced below the hand grip 29 of 'the handle 16. il second shutter 30 has a shutter plate 31 and aprojection or stern 32 provided with a row of teeth 33 adapted to inesh with the gear wheel 26 at a position diainetrically opposite the point of interniesh of the wheel 26 with the teeth 25 of the shutter 22.

rijhe shutter 30 is positioned below the cover plate 11 in the pla-ne of the shutter 22. A flat plate 34 is positioned below the shutters 22 and 30 and is secured to tho top plate 11 preferably by rivets which are arranged in rows as shown in Figure 27 and serve as guiding means for the stems 24 and 32 of the shutters 22 and 30. The rivets 35 also serve to keep the respective rows of teeth 25 and 33 in inesh with the gear wheel 26. The shutter plate 23, when in the position shown in Figures 2 and 3, serves to close the holes 19 and likewise the shutter plate 317 as shown in Figures 2 and 37 serves to close the air holes 21. By turning the linger piece 2S clockwise, the steins 24 and 32 of the shutters 22 and 30 will be slid` lengthwise with a parallel inotion and the shutter plates and 31 will be moved toward each other and open the holes 19 and 21. It desired all of these holes can be opened or parts of the holes inay be opened thus allowing .more or less draft for the fuel within the iron.

Any suitable lower draft holes or apertures can be formed in the base 10 and l have illustrated apertures 36 and niovable cover plates 37. l preferably provide a layer of insulating inaterial as shown at 38 in Figure 3, said layer of insulating inaterial being positioned between the plate 34 and a bottoni plate 39. The plate 39 can be supported by the rivets 35 and I preferably provide spacing portions l() on the rivets 35 so as to keep sufficient space between the top plate 11 and the plate 34 Vto allow the free sliding movement of the I have shown in Figure 3 a hood 4:1 forsaidl latter purpose.

Having thus described my invention what I claim as new and desire to secure by LettersgPatent is:

1. An iron ofthe character described provided with a draft, passage in one part of the iron and a draft passage in another part of the iron; independent shutter porvtions for said passages; and common means operative to effect movement of said shutter portions to open or close said passages or to vary the amount of opening of said passages. l

2. An iron of the character described provided with a draft passage in one part and a draft passage in another part; shutters having rows of teeth; and common operating means for said shutters including a gear wheel meshing with the teeth of each shutter. Y Y

3,. An iron of the character described provided with a draft passage in one part and a draft passage in another part; shutters having rows of teeth; and comi/non operating means for said shutters including a gear wheel meshing with the teeth of each shutter, said teeth being opposed to each other with the gear wheel positioned between said rows ofv teeth. e

4. An iron of the character described provided with an airppassage in its forward part and an air passage in its rear part;

draft controlling shutters for said passagesV respectively having rearwardly and forwardly extending stems; guiding means for said stems; and common means for sliding said stems forwardly and rearwardly to actuate said shutters relatively to the draft passages.A Y

5. An iron of the character described provided with acover having flat portions each having draft holes therein; shutter for controlling the holes of each portion Vand slidably carried by said cover; and common actuating means for said shutters.

Intestimony whereof, I have signed my' naine to this specification, inthe presence of two subscribing witnesses.
