SPECIFICATION formingpart of Letters Patent No. 251,108, dated December 20, 1881.

Application filed September 52:2, 1880. (No model.)

To all whom it may concern Be it known that we, RICHARD H. GARDNER and J. W'RIGHT GARDNER, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Devices for Heating Sad-Irons by Burning Gas, of which the following is a specification.

Our invention relates to a manner of constructing a device to heat sad-irons and tailors irons by means of burning gas which is mechanically mixed with air before reaching the igniting-point, so as to prevent depositing soot upon the surface of the irons.

Our invention consists in the manner of constructing a cylinder or inclosnre of metal with a slot through which the handle of the sadiron may pass ext vriorly, and so that the iron therein placed to be heated shall be in contact with the gas-flame upon its side, or its heel or toe, and not upon its face, and so that the heat absorbe d by contact with the flame shall pass upwardly through the iron in a line of direction parallel to the face of the iron, the object being to utilize the heat by the contact of the metal with the flame and the sad-iron, in such a position that its molecular expansion and transmission of heat through the iron by conduction shall he vertically through a longer line of traverse than when the iron is heated on its face, and there is only the thickness of the metal between the point of contact and absorption and that of departure by radiation. In the former case the heat,having alonger line of traverse with greater resistance to its so that the iron shall be in contact with the flame upon its side, heel, or toe,-within an inclosure of metal provided with a slot for the exterior projection of the handle, and which sad-iron inclosure may be detached from the rest of the device which contains the gas-burning. apparatus and the latter employed for culinary and other uses.

ingapartofit, thereare fourplates of drawings, containing eight figures illustrating our invention, and in all of which the same letters designate the same parts of it.

'Accompanyin g this specification, and form- Figure 1 shows an elevation of the'device,

taken at the front,illustrating the upper inclosure for heating sad-irons and the lower inclo'ssad-iron inclosure removed from the flange and the front wall of the inclosure in part out away, so as to show the interior position of pipe from which the gas enters, the switchwhich regulates the amount of air entering to mix with the gas, and the pipe in which the air and gas rise to burn. Fig. 3 shows the sadiron-heating inclosure removed and separated from the lower section, illustrating the slot for the sad-iron handle and the manner of forming the flange upon its base to connect it with the lower part of the inclosure, where the gas is burned. Fig. 4 shows an inclosure differing in form from that shown in Fig 3, and designed for heating tailors irons in the same manner, the iron being placed in the inclosure vertically, so that the gas-flame at the bottom shall come in contact with its heel or toe, and the iron held in position by inserting the handle in the slot so as to project exteriorly, with the iron resting against the wall of the inclosure.

Fig. 5 illustrates a grate-support to be applied to the lower section for culinary uses when the iron-heating inclosure is removed from the flange. Fig. 6 shows an elevation of 5 the gas-and-air-inixing apparatus, illustrating the position of the external sleeve and the airapertures in the latter. switch by which the sleeve is turned to bring the apertures in the latter opposite those in theannular chamber. Fig. 7 shows avertical section of the mechanism shown in Fig. 6,with

It also shows the the end of the pipe from which the gas and air pass to burn out 0E. This illustration also shows the position of the gas-jet and the annular chamber surrounding it, also the external sleeve surrounding the wall of the annular chamberand one of the apertures in the 4 wall and sleeve as opposite, so that air can enter. Fig.8 shows a horizontal cross-section of the apparatus, taken in the line as w of Fig. 6, illustrating the position of the sleeve, the wall of the annular chamber, and with the openings in the latter. opposite thosevin the sleeve for the admission of air. This also shows the switch by which the sleeve is moved around the wall'of the annular chamber.

t The several parts of the apparatus are designated by letter reference, and their operation described as follows:

.A' and A denote two cylindrically-formed 'inclosures connecting in vertical continuity by means of an ofiset flange or rim, F, formed in the top of the cylinder A and the contracted rim formed in the cylinder A at F, with 'the lower cylinder provided at its top and in the flange offset with the set-screw S, to secure the cylinders when attached. In the side of the: upper cylinder, A, there is formed the vertical slot I, and this is made wide enough for the handle of a sad-iron to pass down from the top within the slot, and so that the iron will be within the inclosure vertically placed and the gas-flame will be in contact with its lower end. Within the lower cylinder, A,

- there is constructed the horizontal brace B, to

support the air and gas delivery pipe P and its connections, this pipe being vertical within the inclosure, and having the flame-orifice O at its top.

At 19 there is shown a gas-jet having a pointed nozzle and a single .round discharge-opening, pointing upward;

,The letter KN designates the wall of an annular chamber, 0, surrounding the gas-jet, and

at S a sleeve arranged to rotate in contact withand aroundthe exterior of the annularchamber wall.

' At 0 O are shown apertures formed in the sleeve, andat O O apertures in the wall of. 1 the annular chamber, and blank places in both the wall and the cylinder between the apertures. When the sleeve is moved around the wall of the annular chamber by the switchhandle H and is stepped with the apertures in both opposite each other, then air will enter theannular chamber through them by the draft force produced by the upward discharge of the gas. and the air and gas passing up will mingle sufficiently to burn at the mouth of the pipe without producingsmoke, and the amount of air entering may be regulated by the switch and the relative position of the apertures in the sleeve to those in the wall of the annular inclosure.

At T is designated a slot horizontally formed in the cylinder-wall for the outward projection of the switch-handle.

A device thus constructed of two parts that are made attachable, as described, and containing our improved device for utilizing gas as a heating means, enables the person operating it to perform several different operations in which heat is required, and this result is due. entirely to the elements of construction which our invention embodies.

While we have shown the inclosures for supporting the S'rtdriI'OllS, in connection with the slot and handles, as circular, we do not limit our invention to the precise form shown, for they may be modified in this respect to receive various kinds of irons, and to support them in precisely the same way and for the same application of heat to the ends of the irons.

We are well aware that gas has been 'discharged into an .inclosure and the draft force produced by it employed to draw in a current of air with it, and which mixed with the gas before the same was burned, and we make no broad claim to such an application, our invention, in this connection, relating to the better manner and means employed to make it applicable.

-Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

A device for heating sad-irons, consisting of the slotted cylinder and inclosure A, constructed to support and heat the irons in a vertical position within said inclosure by means of a gas-flame directed upwardly and in contact with the lower end of the iron thus placed,

and the lower cylinder and inclosure, A, containing the upwardly-directed flame orifice of the pipe P, with the cylinders forming the inclosures made attachable and detachable by I means of a contracted rim formed on thebottom of the upper cylinder and a flange and set-screw upon the top of the lower cylinder I and inclosure, A, as and for the purposes described and set forth.

Signed at Troy, New York, this 31st day of July, 1880.
