To all whom 'it may concern:

'Be it known that I, ALFRED H. DAVIES, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Self-Heated Sad-Irons, of which the following is a specification, reference being bad to the accompanying drawlugs.

the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure l'is a perspective view of the improved self" heating sad-iron; Fig. 2. is a' longitudinal section;,= Fig. 3 is a transverse section;,and Fig. 4 is a. bottom plan view 0 the cover for the body of the iron.

In the drawings 1 denotes the body of the iron preferably of the usual shape having a cavity or chamber in its top formed by forwardly converging upright side walls 2 and any upright transverse end wall 3. The hol low body 1 is adapted to receive a gas burner .41 projected into the same through'an opening5 in its wall ,3, and the open top of said body is adapted to be closed by a removable cover 6. a The latter is shown in the form of a plate shaped to fit upon the body and secured upon the upper edges of its side. and end walls 2, 3 by screws 7, as shown more clearly in Fig. 2 of the drawings. Air is supplied to theburner 4 through openings 8 formed in the end wall 3 adjacent to its lower corners and the 1 heat and products of combustion fromthe burner pass out of the hollow body of the ironthrough transverse outlet .flues 9 formed upon the bottom face of the top or cover plate 6 and adapted to fit into notches. orvrecesses .10. formed in the side walls 2. Any number of said fines 9 may be 'providedbut the preferred arrangement is illustrated in the drawings and consistso'f front and rear pairs of transversely extend- Specification of Letters Patent.

ing-semi-eylindricaltubes cast integral with the bottom of the cover plate 6. The tubes or flues of each pair are in alinement and their inner ends are spaced apart adjacent to the longitudinal axis of the body of the iron so as to receive the heat and products of combustion at the center of the top of the hollow body and conduct the same transversely across the top of the body. It desired, an extra vent may be provided in the upper edge of one of the side walls adjacent its center by the formation of a notch. or recess 11 which is similar to the recesses 10.

Said ventilation opening or recess 11 is adapted to be controlled by a similar shaped damper plate 12 which ispivoted by-a screw 13 upon the adjacent side edge of the cover plate (3. \Vhen the damper 12 is swung upwardly above its pivot the opening 11 will be uncovered to permit of the inlet of'air or the escape of heat and products of combustion and when said damper is swung downwardly it will effectively close the opening or recess 11. 1

The body of the iron is provided. with. an improved handle consisting of a hand" grip 14 of wood or other non-heat conducting material and a supporting and attaching purpose of a heat deflector or shield for the hand grips Said member 15 comprises a plate of substantially the same shape but of slightly less size than the cover plate 6,

from which latter it is spaced by three or more lugs or studs 16 formed upon its bottom face and adapted to engage depressions or seats 17 formed in the top of said cover plate. Rising from the ends of thedeflector or shield 15 are uprights 18 preferably formed integral; with. it and provided at their upper ends with apertures to receive a rod or bolt 19 which also passes through the hand grip 14 for the purpose-of connecting the-latter toisaid uprights. The ends of the hand grip 14} are preferably recessed, as shown at 20, so as to receive the upper ends of the uprights '18 and thereby preventthe hand grip from rotating upon its fastening bolt 19. The deflector or shield plate 15 is fastened to the cover plate 6 by means of a screw 21 passed upwardly through a central opening in the cover plate and into a threaded opening 22 in said plate 15. Said screw 21 retains the spacing lugs 16 in tl1eir-..Seats 17 and the: plate or member 15 is thereby preopening inthe end vented from turning or shifting upon the cover plate.

The preferred form of gas burner is illus I trated and comprises a burner tube formed in its bottom with transverse slits 23 to er;

niit of the escape of gas. The outer en of the burner tube is closed, as shown at 24, and

its. other end which projects through the wall 3 of the iron body is, externally screw threaded and screwed into a'm'em'ber 25 which serves the purpose j of abur'ner supporting and attaching plate and also a gas mixer. Said member 25 consists of a; substantially 'ing one end fo'rmed with a threaded opening 2611p receive'the threaded end of the burner tube'andalso with oppositely projecting "apertured attaching ears 27 for the reception of screws 28 which engage threaded openings inthe end wall 3 of the iron body and serve to attach said member to the same.

The other or outerend of the member "has a screw threaded'o ening-29 to receive formed in the casing 34 and is provided with a the casing or tube 30 o a needle valve, and formed in said end adjacent to the threaded opening 25 is a surrounding or annular series 0 air inlet openings 31. Thevalve caslng 30 has its inner end externally screwthreaded to'engage the threads in the opening 29 and I valve casing 30 is a gas inlet branch 36 having at its upper end arearwardly projecting portion provided with a coupling 37 for the attachment of a flexible gas supply tube 38. The coupling device 37 vcomprises a coneshaped head 39 formed on the extremity of the branchor'pipe 36 to enter a soft rubber tip or connecting tube 40 on the end of the flexible gas pipe or tube 38. Said pipe 36 is formed witha reduced portion 41 in rear of the shoulder 42 formed by the coneshaped head 39 and in rear of said reduced portion is'a screw threaded enlargement 43 toreceive an internally threaded clamping member 44. The latter has upon its outer surface ribs or corrugations whereby it may be readily grasped and rotated and upon its outer end-is anannular longitudinally projecting flange 4:5 to engage the rubber end or tip 40 and effectively clamp the same in the reduced portion 451. and against the shoulder 42, as clearly shown in Fig. 2 of the drawings. This connectionprovides an .eii'ective gas tight oint and one which cannotbe pulled apart by the, movementof the iron when it is being used. The other end of the tube 38 may be suitably connected to spherical body havinternal screw threads- .a gas supply vided with a ru tube of an ordinary gas fixture.

pipe and is preferably pro- In using the iron, gas. is admitted into the" burner tube 4 by opening the, needle valve and the'gas passing from the slits 23 in the burner may be ignited by inserting a lighted match through the opening 11 in the body of the iron. By adjusting the needle valve the flame, of the burner may be regulated as de-. sired and thereby secure the proper flame without regard to the pressure of the gas supply. The pcculiarconstruction of the needle valveand tits arrangement in the spherical body portion of the member :25

causes the proper amount of air to be mixed leer tip to fit over the burner with the gas to provide the most effective flame at the burner. It-will be-notedthat the flames of the burner will be directed downwardly against the bottom of the iron body and will then pass upwardly around the inner face of the side walls 2 ;and then inwardly under the cover-plate 6 and the o'pen inner endsof the transverse flues9, from the outer ends of which latter the heat and products of combustion willv escape. This construction and arrangement, .it will i be noted, is exceedingly simple and provides a highly eflicient self heating iron. Its simplicity enables, it to be produced ata very small cost and. renders it exceedingly strong and durable. It also renders the device exceedingly easy and convenient to use andthe peculiar construction ofthe burner tube and air and gas mixer efiectively 'prevents the flame from the burner shooting back into said mixing chamber. Furthermore, the burner will not be in any way affected. by air currents upon the exterior of the body of theiron and the latter may therefore'be used out of doors or in a room through which there is a strong draft; I

' While the preferred embodiment of the invention has been shown and described in detail, it will be understood that the: invention is not.limited to the specific construction set forth and that various changes in the form proportion and minor details may be resorted to without departing'from' the spirit or sacrificing any of the advantages of the invention. a l i Having thus described the invention what is claimed is: i
