FREDERICK D. VOLLMER, OF MOLINE, ILLINOIS.

SAD-IRON.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed May 1, 1916. Serial No. 94,811.

To all whom 2'2, may concern:

Be it known that I, FREDERICK D. VoLL- MER, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

The invention relates to improvements in sad irons in which gaseous fuel is ignited within the interior of the body portion of the iron for heating the smoothing surface thereof.

It is an object of the invention to provide a self contained iron of this character having the usual body portion of triangular formation and including a smoothing surface, the body having arranged interiorly thereof suitable heat conducting ribs for conveying the heat generated therein upon the smoothing surface of the iron. It is particularly desirable in irons of this character to concentrate the heat upon the smoothing surface of the iron, and at the same time to retain the upper portion of the iron in a relatively 0001 state, and to this end I provide a bafiie plate overlying the heat conducting ribs, which directs the heat upon the smoothing surface of the iron so that this portion of the iron is at all times relatively hot, while the upper portion or cover of the iron carrying the usual handle remains cool, thereby protecting the hand of the operator, even if the iron is used con tinuously for substantial periods.

In carrying out my invention I preferably provide a baffle or deflector of concave formation having a peripheral deflecting flange extending therearound, save at its rear end for directing the heat waves upon the bottom of the iron at each side thereof after the heat has traversed the central portion of the iron. The baflie plate is spaced from the cover of the iron a considerable distance to permit air to freely circulate between the cover and baflie, thereby preventing the cover from becoming unduly hot and necessarily protecting the handle.

With these and other objects (in view, the invention consists in a novel arrangement and combination of parts to be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 illustrates a vertical longitudinal sectional view with parts shown in elevation.

Fig. 2 is a top plan view of the body of the iron;

Fig. 3 is a cross sectional view of Fig. 1;

Fig. 4 is an end view illustrating the burner carrying door; and

Fig. 5 is a top plan view of the deflector.

'Referring now more particularly to the drawings, wherein like numerals indicate corresponding parts, the numeral 1 designates the interior of the body portion of the iron having the usual upstanding sides 2 and smooth surface or bottom 3. The body heat conducting ribs 5, preferably of seg.

mental formation, and of a length less than the length of the body portion of the iron. These ribs project upwardly from the bottom of the iron a substantial distance and are connected near each of their ends with webs 5 of a height somewhat less than the height of the heat conducting ribs 5. These webs 5 provide restricted heat conducting passages for the products of combustion generated within the body of the iron, whereby these products are directed upon the bottom of the iron at the proper point, and also afford seating means for a deflector plate to be presently described. The side walls 2 of the iron at their upper edges are cut away intermediate their ends to provide relatively long air passages 6, while the corners ofthe iron have the usual upstanding portions 6. A cover plate 7 of triangular formation, and being relatively flat, overlies the body and is fastened to the corner portions 6 thereof by suitable fastening screws 8 passing there through, the air passages 6 underlying the cover and permitting the free circulation of air under the plate 7 and serving to retain the cover relatively cool. The usual handle 9 is fastened to the cover toning devices, and this handle is of any well known construction. I

Positioned below the cover 7 and spaced 7 by suitable fas-L therefrom is the deflecting plate 11 of concave formation having the downwardly projecting peripheral flange 13 extending entirely therearound, save at its rear end, and projecting within the body'to a point below the upper edges of the heat conducting ribs 5 and spaced laterally therefrom so as to provide passages 12 between the heat conducting ribs 5 and the peripheral flange 13 for the passage of the heat generated within 7 the iron so as to direct this heat upon the spaced from the heat therethrough and entering sockets within the standards 15, which project inwardly from the segmental heat conducting ribs 5. Two of these standards are shown for the sake of illustration, but any number desired may be used. Referring particularly to Fig. 2 of the drawings, it will be seen that the cover 7 is deflecting plate 11 to provide'an air passage therebetween, the air passing through the opening 6 in the wall of the body of the iron and freely circulating through a closure which permits ing between the cover and the deflector, so that the cover is at all times retained in a relatively cool condition. It will thus be seen that if the cover is retained in a cool condition the handle 9 will also be protected from the heat generated within the iron so that'this handle is also cool and the hand of the user is therefore protected and cannot be burned by grasping the handle 9.

Pivotally attached to the rear end of the iron is the swinging closure 4 having cutout portions 15 arranged in its sides and upper edge for'the passage of air to the burner,

the closure being pivotally attached to the body of the iron by the vertical pin 16 passhinge opening 16' within the clo-sureplate, and the cover 7 and entering asocket 17 within the bottom of the iron. The closure at its upper end near one side is provided with a counter sunk portion or pocket 17' into which the pointed end of a fastening screw 19 passing through the cover enters to retain the closure in a closed posi tion. A cutout portion 20 is arranged within the bottom of the iron underlying the closure, and allows the passage of air to the interior of the iron, it being seen that in the present construction the air passages are provided around the edges of the door or an ample supply of air to be admitted to the interior of the iron. A stop or shoulder" 21 projects upwardly from the bottom of the iron at one end and limits the inward movement of the pivoted door at. Carried by the closure and preferably formed integral therewith is a burner 22, which is slightly inclined and points toward the bottom of the iron, this burner having fitted around its ends a woven screen 23, retained in position by an annular ferrule 24. Exposed eXteriorly of the door is a coupling portion 25 having an interiorly threaded socket receiving the usual gas feeding tube 26, by which gas is admitted to the burner when the iron is being used. The door burner and pipe connections are formed as a unit,thereby furnishing a simple and eflicient structure. A mixing valve 27 of any well known construction is disposed at the end of the tube 26 to properly proportion the amount of air and gas fed to the interior of the iron.

From the foregoing description it will be seen that when it is desired to light the burner 22, the fastening screw 19 is raised and the door 4: swung open, at which time the burner is lighted and the closure then closed. By having the burner inclined the products of combustion are directed along the surface of the iron and enter the heat conducting space disposed within the body thereof, and after traversing the bottom of the iron within this space the heat waves will travel upwardly engaging the deflector 11, which then again directs the heat product downwardly through the passage 12 between the rib 5 and flange 13 so that the heat is not only concentrated upon the bottom of the iron at the center thereof, but also upon each side of the iron, the cold gases being permitted to escape through an outlet 28. The heat is prevented to a great extent from passing around the front and rear ends of the iron by the webs 5, as these webs upon which the flanges of the deflector plate rest provide passages for directing the heat products in the manner as has been described so that the heat is concentrated upon the bottom of the iron at the points where it is most desirable.

Having thus described my invention what I claim is:

1. A sad iron comprising a body of triangular formation, a door having cutout air feeding openings in its sides and top edge hinged to said body, a burner carried by the door and being disposed in an inclined position for directing the products of combustion upon the bottom of the iron, a movable locking device carried by the iron and engaging said door for locking the same in a closed position, a stop for limiting the inward movement of the door, and air feeding opening in the bottom of the iron underlying the'door, and means for feeding fuel to the burner.
