Specification of Letters Patent.

' Patented March 13, 1966.-

Application filed September 9, 1904- Serial No. 223,870.

Be. it known that I, FREDERICK W. KEL- LERMAN, a citizen of .the United States, residing at Weymouth, in the county of Norfolk and State ofMassachusetts, have inventeda new and useful Improvement, in Sad-Irons, of which the following is a specification.

This invention relates to sad-irons, and it consists, substantially, in the construction and combinations of parts hereinafter particularly described, and pointed out in the claims.

The invention has reference more especially to self-heating sad-irons .in which the vapor of gasolene, naphtha, or other vaporiza le fluid is employed as the heating agent; and one ofthe principal obj ectsofthe invention is to overcome disadvantages and objections' common to many devices of this class at present muse andalso to provide 'a sadiron which is comparatively simple in its embodiment as well as inexpensive to manufacture. g i

A further obj ect isto provide a self-heating sad-iron which may be easily manipulated: and controlled and which is eflective and re:- liable in o eration, besides possessing the capacity for ong and repeated service. f

A st ll further object is to provide a sad iron the cooperative elements ofwhich may be. easily taken apart and again put together and whichmayibe readily repaired and re'-.

, placed by others when wornor broken.

' which The'above and additional objects are attained by means substantially such asare illustrated in theaccompanying drawings, in;

improvements herein shown I employ a 'sad-. I

iron having a body of special construction and within which is supported a specially-constructed movable horizontal partition dividing the interior, of the body into an upper, and

forward chamber and a lower combustionchamber, in which latter is mounted a vaporburner, also of special construction. S upported in the upper chamber is a vapor-generator of special construction, in communication with which is a conductorfor the vaporizable fluid leading from the supply-tank for such fluid, suitable valves being employed to regulate the passing of the fluid to the conduotor, as well as the passing of the generated vapor to the burner.

Other specially-constructed elements are also employed, as will hereinafter be more fully explained, and

while I have herein represented my improvements in a certain preferred embodiment it will be understood, of course, that I am not limited thereto in precise detail, since immaterial changes. may be resorted to coming within the scope of'my invention.

Reference being had to the drawings the designatingcharacters marked thereon, '1 represents thebody of the sad-iron in entirety, the same being hollow and comprising the bottom 2 and the side walls 3 3, con-' verging at their forward ends andunited to form the nose 4, said side walls being united at their rearward ends by a rear wall 5. Each of the side walls 3 3 is provided with a series of holes or perforations 5 at the forward upper part. thereof, (see Fig. 1,) and secured to the inner sides of said walls by rivets 5' are a number of properly-disposed brackets 6, on which the top plate or cover 7 of the said.

iron is supported, said top plate being fastened in place by means of screws 8 inserted through openings 8 therefor in said. top

plate and throughregistering openings 8*" in the brackets. "In order to prevent as much as possible the heating of the top plate, I preferably dispose beneath the'same a sheet TIO' 9 of non-conducting material, such as asbestos, the said fastening-screws 8 for the top plate also serving to fasten said sheet in place, the latter having openings therein corresponding to openings 8 and 8 through which the screws 8 extend. The top plate presents the same outline in plan view as'is presented by a plan view of the body, and it is formed near the forward or tapered end thereof with a series of holes or openings 10, with which may be made to register corresponding' holes or openings 11, formed in a rotatable valve-plate 12, having an operating-crank orknob 13 and mounted to work on a pin 14 extending through a central opening therein and secured in the top plate by means of a nut 15 on the under side thereof. The holes or openings 10 are in communication with the conical upper extremity 16 of a vertical flue or pipe 17, the lower extremity of which terminates in a rearwardlyextending branch 18, resting on the upper surface of the bottom 2. The edge of the said conical extremity of the flue is flanged at 19 and is riveted to the under side of the top plate at 20, this being a convenient way of fastening the flue in rigid position, although other means may be employed therefor, if desired, it being understood, of course, that the abestos sheet 9 is cut out beneath the openings 10, so as to offer no obstruction to said openings.

Mounted upon the top late are supports 20 for a handle 21 of wood or other non-eon ductor of heat, the bases 22 of said supports being secured in place by means of screws 23, (see Figs. 1 and 7,) and formed approximately centrally of the top plate is an opening 24, which is closed by a valve-plate 25, rotating on a screw 26, the asbestos sheet 9 being correspondingly cut out, so as to permit of access to the interior of the body 1 of the sad-iron through said opening 24.

The hollow body 1 is divided interiorly into a main chamber, comprising a space 26 above the combustion-chamber and a space 27 in front of the same and a lower combustion-chamber 28, by means of a forwardly and rearwardly slidable horizontal partition 29, provided at its forward end with a depending apron 30, the lower edge of which reaches practically to the upper surface of the bottom 2 and is notched at 31 to permit of the entrance to the combustion-chamber of the flue branch 18. (See Fig. 1.) Said partition is of special construction, and up- Wardly through which projects a tube 33, leading from and communicating with a burner 34, secured to the under side of the partition 29 by means of a screw 35 or in any other preferred way. This partition 29 is supported upon ledges 36, projecting from the opposite inner surfaces of the side walls 3, and is provided with pins 37, working in slots 38 in said ledges, the length of said slots being such as to limit the forward movement of the partition to prevent the same from striking against or coming into contact with the flue 17, and when the partition is at the limit of its rearward movement the rearward edge thereof abuts the inner surface of the rear wall 5 of the sad-iron. Owing to the converging character of the forward portions of the side wallsof the sad-iron, the side edges of the slidable partition 29 are trimmed oil at 39, so as to enable the partition to be moved forwardly the required extent whenever desired, the said partition being formed for a suitable distance from its rearward edge with a central longitudinal slot 40 and provided at the forward and closed extremity of said slot with an oil or starting pan 41, having side flanges 42 and 43 extending all around the same, (see Figs. 1, 2, and 3,) said pan comprising rearwardly-extending branches 43", as shown.

At the rearward portion thereof the partition 29 has secured to its under side by means of rivets 29" substantially a Y-shaped bracket 29", the diverging members 29 of which extend to either side of the slot 40 in said partition, and the pendent vertical member 29 of which is below and substantially intermediate the sides of said slot. Said vertical mem ber is formed with an opening 30 in which is screwed the threaded portion of a pin 30' extending through an opening therefor in the rear wall 5 of the said iron, and the pin is provided with a knob or handle 30 at its outer end to be taken hold of to slide the partition 29 either forwardly or backwardly upon its supports.

The burner 34 is constructed of a hollow body 44, having hollow downwardly-diverging side members 45 communicating there with, the ends of said members being downwardly and outwardly inclined at 46 and the lower longitudinal edges thereof each being formed with aseries of jet-orifices 47, at which the fluid vapor is burned in the combustionchamber 28. Extending upwardly through said slot 40 at its inner extremity and also between the branches 43 of the starting-pan is a vertical tube 48, upon the upper end of which is mounted a vapor-generator 49, which is practically a cylinder, having heads 50 and 51 formed, respectively, with central openings 52 and 53, the said opening 52 havingfitted therein the hollow stem 54 of a nozzle or head 55, having the discharge end thereof directed downwardly. In machining out the bore of said nozzle said bore is formedv all the way through the same, being closed at the upper extremity thereof by means of a screw-plug 56, as shown. Fitted in the opening 53 of the head 51 of the generator and abutting at its forward end against the inner surface portion of head 50, surrounding the opening 52 in said head, is an internally-tln'eaded tube 57, leading to stem 54 of the injector and pro- 1815255 I j e vided with opening 58, communicating with the interior of the generator, (see Fig. 1,) said tube projecting'beyond the head 51- of the enerator at its rearward end-"and pro: vided ating-stem 60 projecting through an opening therefor-in the rear wall and provided with a handle 60*. Said stem works in a stuffing box 61, screwed a onthe externally-thread-V ed rearward end-o said tube 57 and by turn- 7 ing the stem in the-proper direction the valve will be moved rearwardly, so that when its forward conical end reaches the opening 58v in tube-57 communication will be established between the interior of the generator and the forward portion of said tube.

Connecting with the lower end of tube 48 is the forward end of a horizontal tube 62, which is preferably enlarged in diameter for a part of its length, as shown at 63, said enlarged portion extending beyond the rear wall 5 and having the'outer end thereof externally screw-threaded and fitted into a tubular member 64 of a valve-casing 65, having a chamber 66, from which leads an internallythreaded depending neck 67, through which works the threaded stem 68 of a conical valve 69, which may be operated to open-or close the and provided in its top with afilling-opening closed by a screw-cap 76. Abrace 77 ex-' tends from the inner side of the tank to the adjacent support-2O for the handle 21, and the inner and under sides of the tank are pro-' vided with a guard 78 to protect said tank as the enlarged dportion 63 thereof is asleeve 81 much as possible from heat proceeding from the sad-iron. To relieve the vacuum in the chamber caused by the flow of fluid therefrom, I may form a vent 79 in the top of the tank, through which air may enter the tank above the li uid, and it will be noted that the interior of t e enlargedportion 63 of said tube 62 is filled with cottonor. similar material 80 for straining the fluid as it passes to the generator 49. from the tank. we Surrounding a considerable portion'of the tube 62 and of increased ameter oversaid enlarged p rtion 63, the said sleeve projectin through an opening therefor in the rear wal 5 and hav-' ing its outer end externally threaded at 82 and receiving anut'; 83 170 hold the sleeve in placez 1A set=scr3w 8l is inserted through an op'enihg: therefor in ith'e sle'eve andib e ars upon'i the-tube 6 2H lhe' s aid sleev extends within; the Slot .40 l in: tlhe partition' 29 part: of the with a screw-valve 59, having'an oper- :always be at hand when needed sleeve lying above said partitiona d part below, as shown'in Fig. 1. This is a convenient assemblage, since the slot 40 is thereby almost completely filled up in the rearward position of partition 29, thuspreventing toa great extent the passing of products of cornbustion from, the combustion-chamber to the The spaces between the in upper chamber. ner surface of the sleeve and the outer surface of the tubular members 62 and 63ar'e' filled with asbestos or other non-conducting material-85 toprevent as-much as possible the heating of the said tube portions 62 and 163, and ther'ebyle'ssening the liability of heat being conducted to the valve casing and the .tan 7.

, Therear wall 5 of the sad-iron is provided I with preferably vertically elongated open' ings 86 leading to the upper chamber 26, and ,vrith'other openings 87,leadingto the combustion-chamber 28, while hinged to said rear f wall at 88 are doors 89, which may be swung :against the wall before said openings 87. The

doors are provided with vertical edge flanges 90, Figs. 2and 3, to cause them to set outwardly from the rear wall-when closed, and .thus they do not interfere with the entrance ;of air to the combustion-chamber via the openings 87 ,serving as they do,practically, as Y guards to deflectlaterallytheflames of the burner issuing through said openings. Said doors are preferably provided withcatches 91 (dotted lines, Fig. 8) to hold them in position I against" the rear wall,' as-s'hown. 7 Instead of providing an air-vent in the top of the fluid-supply tank 7 4, as in Fig. 1, I may IOO subject the fluid to air-pressure in the tank, v

and for which purpose I- resort to the construction shown in Fig.9. Thus in said fig- -ure the tank 92 is provided-with the usual filling-opening, closed bya screw-plug 93, and

is provided in addition with a nipple 94, lead-' ing to a hollow'casing 95, in the bottom -of which is an air-port 95 normally closed from beneath by a'conical sprin -controlled valve 96, the stemof which wor s in a spider 97. .The end of the flexible-tube-outtake of any ordinary small hand-pump may be applied to the nipple to force air intothe tank above the liquid, and in order that such a ump may the tank with a separate compartment 98, in which I place a hand-pump 99 of ordinary form, whichmay be removed at any time for the purpose mentioned.

In operation the slidable partition 29 is moved forwardly to carry the starting-pan 41 construct to position beneath the injector 55, and then' I the valve 69 is manipulated so as to cause some of the va orizable fluid in the tank to i flow ithrough t etube anembers 63," 62; ahd' 48y thenc'e tothe interior of the' vapor-gener ator .49, whereupon-the screw-valve59i is thi fluid in the I generator 1 to drip i inte lthe properlymanipulatec l tocausea'q ufintity of starting-pan through said nozzle. On the filling of the starting-pan the said screwvalve 59 is rever'sely manipulated to close the opening 58, thereby shutting ofl further supply of fluid to said pan, and then after a suitable quantity of the fluid has been allowed to accumulate in the generator the valve 69 is closed and the fluid in the start ing-pan ignited by a lighted torch inserted through the opening 24 in the top plate 7. The flame from the pan heats the generator, and by the time the oil in said pan is consumed the fluid in said generator has been converted into vapor. The screw-valve 59 is now again manipulated to open up communication between the interior of the generator and the forward portion of tube 57, and thus the vapor inthe generator passes to the nozzle and is delivered downwardly to the burner through the tube 33, it being understood that in the meantime the slidable partition 29 has been moved rearwardly to carry said tube 38 directly beneath said nozzle. After this a regulated supply of fuel is fed to the generator by the means shown and described, the interior parts having now become sufficiently hot to maintain the production of vapor in the generator. As the sad-iron is moved forwardly in use currents of air will enter the chamber 26 27 through openings 5 of the side walls, an outlet therefor being had through the elongated openings 86 in the rear wall 5, and then as the sad-iron is moved backwardly the operation will be the reverse. Aircurrents will enter the chamber 26 27through the openings 86 and will seek an outlet through said openings 5, and as such aircurrents enter the chamber through one set of openings they tend to force through the other set any waste products of combustion which may have accumulated in or found their way to said chamber. Quantities of the air will be induced to enter the burner by the force of the vapor passing thereinto from the nozzle leading from the generator, and this mixture produces a clear flame at the burner of great heat intensity. Air is also admitted to the combustion-chamber through the openings 87, both to support combustion and create draft sufficient to cause the waste products of combustion to pass upwardly through the flue 17 and out through the series of openings 10 in the top plate.

It will be understood that while provision has been made for carryin off the products of combustion from both t e chamber 26 27 and the combustion-chamber 28 there is a very small percentage of the vapor which remains unconsumed, so that such products are reduced to the minimum of quantity or volume, with the result that no unpleasant odors are apt to issue from the sad-iron when in use.

It will be also noted that my improved burner 44 is so constructed as to direct the flames thereof downwardly against the bot tom 2 of the sad-iron, and which renders the iron much more effective for its intendedpurposes. In addition to the forward part of chamber 26 27 accommodating the flue 17 it also provides space to permit the partition 29 to be moved forwardly in the manner described.
