Specification of Letters Patent.

Patented July 5, 1910.

Application filed August 10, 1909. Serial No. 512,113.

To all whom it may concern:

Be it known that I, MONROE SUNSHINE, ofthe city, county, and State of New York, have invented certain new and useful Improvements in Sadlrons, of which the following is a full, clear, and exact specification.

My invention relates to certain new and useful improvements in sad irons, and especially those provided with gas heating attachments, which operate to maintain the iron at the required temperature.

It has for its object the provision of means which will utilize the gas consumed to the best possible advantage, so that a minimum quantity may be used, and thus effect a maximum economy in the operation of the iron.

Another object is to provide an iron with a removable burner, which can be inserted and withdrawn therefrom with the least possible trouble and manipulation, and at the same time provide means whereby the burner shall always be inserted in the proper manner and be held firmly secured in place against removal or disturbance.

lVith these objects in view I have illustrated one form of my invention inthe accompanying drawings, wherein- Figure 1 is a side elevation of an iron with the burner in place. Fig. 2 is a rear elevation thereof, Fig. 3 is a top plan view of the iron with the handle and handle plate removed. Fig. 4 is a side sectional view, taken on lines oc-m of Fig. 3, Fig. 5 is a cross-section on line y-y of Fig. 4. Fig. 6 is a plan of the under side of the heat distributing plate. Fig. 7 is a side elevation of the burner, and Fig. 8 is a face view thereof.

Similar reference numerals indicate like parts in all the drawings.

As will be seen the iron proper is preferably formed of a metal casting 1 with a heat chamber, 2, and a burner recess, 3, communicating therewith, the heat chamber being open at the rear and provided with a hinged door or gate, 4, for closing the same. This door is shown hinged at 5, and a latch, 6, pivoted at 7 to the upper rear portion of the casting, is adapted to hold the door closed when the iron is in use. The said door 4 has a loose fit, as shown in Figs. 2 and 4, to permit the escape of the products of combustion.

Upon the upper face of the casting projecting bosses, 8, 8, 8, 8 are formed, and a handle 9 formed integral with the handle plate, 10, is adapted to be secured in place upon the bosses by bolts, 11, 11, 11, 11, which pass through apertures in the handle plate, and are adapted to screw into threaded recesses in the said bosses, 8, 8, 8, 8. A lug or stop 12, is also formed upon the top of said iron, for instance, as shown in Fig. 3, as an extension of one of the bosses, which lug serves to limit the rotation of the burner as will be hereinafter described.

The handle and handle plate are mounted upon the studs in order to remove the same as far as possible from the heat of the iron, and to prevent the handle from absorbing the heat generated, and the air space between the upper surface of the iron and the handle plate permits the passage of air which also tends to keep the handle cool.

The burner, 13, may be of any desired type, but I prefer to use a plug burner, such as that indicated in Figs. 7 and 8, which consists generally in a short, hollow cylinder or plug, having a flat segment, 14, provided with a gas aperture, which latter is covered with a wire gauze or screen, 15, to serve as a flame shield, according to the principle of the well known Davey lamp.

The burner is provided with a hollow stem or supply pipe, 16, through which the gas passes, and also with a flange, 17, having a projection, 18, and this flange is preferably provided with a shallow recess or slot, 19, for the purposes hereinafter described. The burner is of sucha size as to fit snugly within the burner recess 3, in the iron, and the pipe, 1G, is of such diameter is will supply the necessary amount of combustiblegases. Any suitable means, such as a rubber hose or the like, may be utilized for connecting the iron with the gas supply. lVithin the gas chamber, 2, I provide a heat distributer or gas deflector, which consists of a plate having downwardly extending flanges, 20, 2O and 21, 21, the former being located generally along the sides of said plate, serving as heat inclosures, and form a combustion chamber, while the latter are located as shown, and within the outer ones. The heat distributer is entirely open at the bottom and at the forward end, 22, and at the rear at an opening 23, is provided to enable the operator to examine the flame while the iron is in operation. The heat distributer is readily removable from the combustion chamber, and is held in place therein by a set screw, 24, passing through the top of the iron and bearing upon the surface of the heat distributer, as shown in Fig. 4.

The forward edge of the handle plate, 10, projects somewhat beyond the bosses S, 8, as shownv in Fig. 1, and a set screw, 25, is threaded into an aperture therein, and is adapted to engage the slot, 19, of the burner flange, 18, when the latter is in place, and thus serves to hold the burner firmly in the proper position when it is inserted in the burner recess.

The operation of the device will be readily understood from the foregoing. When the iron is desired for use, all that is necessary is to insert the burner in the burner recess, turning the same at right angles to the position shown in Fig. l. A quarter turn of the burner then will bring the flange, 1S, under the forward extension of the handle plate and against the lug, l2, and the said screw, 25, can then enter the slot, 19, and hold the burner firmly in place. To remove the burner the foregoing operations are simply reversed, and thus I have provided a very simple and effective and quickly operable means of securing the burner in place.

lVhile I prefer to use a lug, 12, for limiting the rotation of the burner in the iron it is evident that it may be dispensed with, and the set screw alone used for holding the burner in the proper position. If the lug is `dispensed with, it is preferable to employ the slotted flange, but this also is not essential, as the set screw can be used alone to hold the flange and the burner in place.

As shown in Fig. 7, the flange, 18, and burner segment, 14, are arranged practically in alinement, and when the burner is in place the gases emitted through the screen, 15, and ignited are projected into the combustion chamber under pressure. A certain amount of these gases are forced between the

central flanges

21, 21 as indicated by the arrows, but a portion of the gases are also deflected outside the flanges, 21, and so back into the space, 26, where they meet the incoming gases through the center aperture, and by this arrangement I obtain a very complete distribution of the burning gas through the combustion chamber, and practically prevent any from being forced back through the passage, 23, which is therefore always accessible to the eye of the user, and enables him by merely opening the door, il, to ascertain at any time while the iron is in use, the exact condition of the flame therein.

It is obvious that many modications and changes may be made in my invention without departing from the spirit thereof, and I therefore do not limit myself to the specific construction shown, but

lVhat I claim and desire to secure by Letters Patent is:

1. The combination with a sad iron having a heat chamber, a burner recess communicating therewith, and a positioning stop or lug, of a rotatable and removable burner provided with a gas vent and a positioning flange adapted to contact with the stop on the iron when the gas vent registers with the opening' between the heat chamber and burner recess.
