erases.

To all whom it may concern:

Be it known that l, WALTER W. LIND, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

The invention relates to improvement-s in sad-irons of the so-called self-heating class, and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

r1`he iron of my invention comprises a lower part which is hollow and designed to contain a suitable fuel for keeping the iron hot, and an upper part carrying the handle and adapted to be placed downwardly upon and be detachably secured to said lower part.

The object of my invention is generally to increase the value, efliciency and convenience in use of sad-irons of the class to which my invention pertains.

One purpose of my invention is to provide a structure affording an improved combustion chamber so that the iron may be properly heated, and another purpose of the invention is to enable the convenient cleaningout of said chamber whenever desired.

A further purpose of the invention is to provide means for detachably securing the upper part of the iron to the lower part thereof in various adjustments so as to regulate the drafts through the combustion chamber.

Another object of the invention is to provide an adequate body of metal, without undue weight, in the bottom of the iron so that the iron may not with undue rapidity be come cooled on its ironing face, especially while ironing damp fabrics.

The invention will be fully understood from the detailed description hereinafter presented, reference being' had to the accompanying drawings, in which:

Figure 1 is a top view of the lower portion or section of the iron of my invention; Fig. 2 is a central vertical longitudinal section of the complete iron; Fig. 3 is a central vertical transverse section of the same on the dotted line 3--3 of Fig. 2; Fig. 4 is a detached top view of the mechanism carried by the top section of the iron for securing it to the lower section thereof; Fig. 5 is a top view of Speeication of Letters Patent.

Application filed January 28, 1916.

the complete iron, and Fig. 6 is a detached sectional view through a portion of the top section of the iron on the dotted line 6-6 of Fig. 5.

In the drawings 10 designates the lower section of the iron, 11 the top section thereof, and 12 the handle connected with said top section by suitable standards 13. The top section 11 comprises a top-plate 14, a downwardly encompassing edge-flange 15, and outlet flues 16 provided at opposite sides of the front and rear ends of said top section and formed by upwardly and outwardly curved portions 17 of said top-plate 14 eX- tending above the adjacent portions of the flange 15 and leaving openings above said flange to constitute said flues, as indicated in F ig. 6. The top-section 11 carries the means for connecting it with the lower section 10, and these means comprise two suitably spaced-apart transverse bars 18 pivotally mounted, on end trunnions 19, in the sides of the flange 15, arms 20 extending downwardly from said bars 18 and having oppositely extending dogs 21 at their lower ends, a longitudinal bar 22 below the bars 18 and having in openings in its ends transverse rods 28, inclined lingers 24textending downwardly and outwardly from the bars 18 and below the rods 28 (Fig. 2), and a central pivot-pin 25 connected with the bar 22 and having at its upper end a button 2G preferably provided with a hinged loop-handle 27.

rEhe top 14 of the upper iron-section 11 is provided with a longitudinal slot 28 adapted to receive the button 2G, which when it is in line with said slot may be depressed into or pulled upwardly through the same. 'Vhen the button 2G is pressed downwardly into the slot 2S, it depresses the bar 22 and rods against the fingers 24 and thereby compelling the bars 1S and arms 20 to rock downwardly and inwardly toward each other, with the result of releasing the dogs 21 from the lower section 10 of the iron and leaving the upper section 11 free to be lifted from said section 10 or adjusted upwardly or downwardly thereon. W'hen the button 26 is pulled upwardly through the slot 28 it elevates the bar 22 against the bars 18 and causes said bars and their arms 20 to rock outwardly from each other, with the result that the dogs 21 are forced into engagement "Jv Zvi.

23, causing said rods to press downwardlyi with the lower iron-section 10, for connecting the upper and lower sections of the iron together. After the button 2G has been pulled upwardly through the slot 23 for connecting together the upper and lower sections of the iron, said button is given a one-quarter turn to cross the slot 2S and lock the dogs. 21 in their engaging relation to the lower iron-section 10. rihe button 2G is provided with a pivoted loop 27 for convenience in manipulating it, and said loop is pivotally connected with the button 2G so that when the button is across the slot 23 the loop may be folded downwardly out of the way of the hand of the person using the iron. The arms 20 are thus rocked toward each other to release the upper section 11 from the lower section 10, and they are rocked from each other to connect said sections together, and as shown in Figs. 3 and a there are two arms 21 at each side of the iron.

The lower section 10 of the iron is a hollow shell comprising a bottom 28, vertical sides 29 and interior frame 30, and the top section 11 covers the section 10 and its sides 15 pass downwardly7 over the sides 29 of the section 10. The sides 29 of the lower section 10 are recessed or cut away at opposite sides of the section, as at 31, to receive the downwardly extending arms 20, and at the opposite edges of the recesses 31 the sides 29 are formed with a series of serrations or teeth 32 to interlock with the` dogs 21 of said arms. Vhen the top section 11 is applied to the lower section 10, the dogs 21 will be interlocled with such of the teeth 32 as will leave the top section in the desired relation to the lower section, the series of teeth 32 aording a means of adjustment enabling the top section to be elevated or lowered in accordance with the amount of air-draft to be permitted through the interior combustion chamber of the iron. The lower section 10 is not only recessed at its opposite sides, as at 31, but is also recessed at both ends, as at 33, and these recesses 31, 33 are located at a suitable elevation above the bottom ofthe section 10 and afford draft spaces for the air required for combustion, which spaces may be varied in size by the vertical adjustment of the upper section 11 on the lower section 10, the flange or skirt 15 of the top section 11 serving to more or less cover the recesses 31, 33 as said section is adjusted upwardly or downwardly.

The bottom 23 of the lower cast section 10 is formed on its upper surface with a series of vertical somewhat cone-shaped studs 34 which are distributed over and integral with said surface. The studs 34 are beneficial in several respects, one being that the fuel is placed upon them and that they allow the air to find its way below the fuel. The studs 34 are also of advantage because they hold the heat and prevent the bottom 28 from cooling with undue rapidity, thus allowing the iron to be constantly used a greater length of time. Self-heating irons, espe-I cially when used on damp clothes, give off their heat with some rapidity, the bottom of the iron being comparatively thin. rIhe studs 34 not only serre to support the fuel and aid in securing proper combustion but afford an increased body of meta-l in the bottom of the iron without creating undue weight in the same or unduly reducing the capacity of the fuel chamber. The shell 30 extends entirely around the inner walls of the lower section 10, as shown in Figs. 1 and 2, and at its opposite sides, adjacent to the recesses 31 in the sides of said section 10, the body of the shell inclines downwardly and inwardly, forming shields 35 which while preventing the spilling` of the fuel through said recesses do not obstruct the air draft through the same, as may be seen by reference to Fig. 3. The lower edges of the shields 35 are formed with a series of recesses 36, which form draft passages. The sides of the shell 30, at the front and rear of the shields 35 are cut away, as at 37, and the front and rear ends of the shell are formed with draft passages 3S. rlhe shell 30 may be made of sheet metal and sprung into the lower section 10 or it may be riveted to said section or left free to be readily lifted therefrom. The shell 30 guards trie recesses 31, 33 without obstructing the drafts through the same and by being cut-away or recessed at 37 avoids occupying undue space in the combustion chamber of the iron.

ln the employment of the iron the top section 11 is removed and the fuel placed in the bottom section 10, as usual, and in restoring the top section to the section 10, said top-section will be adjusted downwardly to the extent desired but leaving the lower portions of the side recesses 31 and end recesses 33 uncovered for the passage of air through the same. The draft passages at 31 and 33 may at any time be varied by adjust-ing the top-section l1 vertically with relation to the lower section 10, so as to modify the draft through the combustion chamber as the conditions therein might require. The draft outlet from the combustion chamber is through the flues 16. The recesses 31, 33 at opposite sides and ends of the iron not only provide for the adequate admission of the air but enable the ash to be blown, from time to time as may be dcsirable, from the combustion chamber. y
