SELF-HEATING SAD-IRON.

Application filed May 31, 1913.

Specification of Letters Patent.

Patented Apr. 7, 191e.

serial No. 770,984.

To all whom it may concern Be it known that I, DANIEL W. YOUNG, Jr., a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Self-Heating Sad-Irons, of which the following is a specification.

My invention relates to improvements in self heating sad-irons and has particular reference to that class thereof designed for use where kerosene is used as the fuel.

The object of my invention is the production of a sad-iron as mentioned which will be of durable and economical construction and efficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

rlhe invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which- Figure l is a central vertical section of a sad-iron embodying my invention, Fig. 2 is a horizontal section taken on substantially line w-w of Fig. l, Fig. 3 is a vertical transverse section taken on substantially line m-m of Fig. l, Fig. l is an enlarged vertical section taken on substantially line y-fy of Fig. 2, Fig. 5 is an enlarged detail section taken on line z--e of Fig. 2, Fig. 6 is an enlarged bottom plan view of the cover of the body of the iron, Fig. 7 is an enlarged front elevation of a fitting used in the connection of the drain pipe of the fuel tank with the generator of the iron, and Fig. 8 is a perspective view of the outer end of said drain pipe of the fuel tank which engages with the fitting shown in Fig. 7.

The preferred form of construction as illustrated in the drawings comprises a hollow body l of usual form, open at its upper side. Arranged within the body l in superposed relation are the generator 2 and the burner 3, the latter being of course arranged below the former. The burner 3 is supported in operative position by means of a depending arm 4t provided at the inner end of the generator 2, the arm l embracing the lower end of a substantially U-shaped pipe section 5 which serves in the capacity of a mixing chamber, one end of the burner 3 being threaded into the corresponding end of the member 5, the latter in turn being secured to the supporting arm 4 by means of a set screw 5. The upper end of the member 5 is spaced from the discharging orifice of the generator 2 in order to effect a thorough mixing of the gas issuing from said orifice before reaching the burner 3.

The outer end of the generator 2 is provided with an enlargement 6, rectangular in form, which snugly 'fits a slot 7 of corresponding form provided in the upper edge of the rear wall of the iron. The lateral edges of the enlargement 6 are of channel form, as shown, for embracing the adjacent edges of said slot whereby said generator and hence th'e burner and mixing chamber are supported in operative position. The lower edge of the enlargement 6 is provided with depending pointed projections 8 which engage notches 9 provided in the bottom of the slot 7, this construction serving to securely hold said enlargement 6 in position in the slot 7 preventing free movement.

The burner 3 is provided at its under and upper sides with spaced transversely eX- tending slits l0 and ll respectively through which the fuel escapes for combustion. The openings l0 are larger than the openings ll in order to permit of escape of a greater amount of gas to support a primary flame for the heating of the bottom of the iron larger than that which will be supported at the upper side of the burner for heating the generator 2 in the generation of the liquid fuel into gas. The upper side of the bottom of the iron body is hollowed out slightly to conform substantially with the formation of the burner, and vided at either side of the burner, arranged in alinement with the openings 10 thereof which serve as obstructions to prevent spreading of the jets into engagement with the lateral walls of the iron. Without the provision of obstructions as mentioned the flame at the under side of the burner spreads over the entire bottom of the iron and impinges against the lateral walls of the body of the iron, considerable fuel being thus wasted in the heating of said walls. With the present construction, the flame will be confined to the bottom or operative portion of the iron body and thus economy in fuel effected.

Arranged at the reaward end of the iron at one side thereof is the fuel tank l2 provided with a filling plug 13 of ordinary construction. Leading from the bottom of the projections 12 are protank 12 is the fuel outlet pipe 14 the outer or lower end of which is connected with a nipple 15 formed at the rearward end of the generator 2. Said end of said outlet pipe is connected with the nipple 15 through the med-ium of a fitting 16, one end of which is threaded into said nipple, the end of said outlet pipe loosely fitting in said fitting as clearly shown in Fig. 4. At the extremity of the pipe 14 are provided diametric ears or lugs 17 which engage recesses 17 provided in the member 16, which serve to lock the pipe 14 against relative rotary movement in said member 16 and hence to maintain the tank 12 in upright position. Snugly fitting the pipe 14 adjacent the end thereof is a tapering' collar 18 adapted to engage a Y seat 19 formed in the member 16: Loosely mounted upon said pipe 14 is a screw cap 20 adapted for threaded engagement with the outer end of fitting 16. The cap 2O engages against the outer end of the collar 18 serving to force the latter into secure engagement with the seat 19, the latter in turn pressing said collar into close engagement with ythe pipe 14, whereby an absolutely tight joint is effected without the use of packing such as is now generally used. The bottom of the cap 20 which engages against the outer end of collar 18 is beveled, as shown, inorder to also press said end into close engagement with the pipe 14, when said cap is threaded into the member 16 to operative position.

The flow of fuel to the generator is governed by a valve 21 which is threaded in the outer end of said generator, an exteriorly g positioned hand wheel 22 being provided for operating said valve. VThe inner end of said valve `is adapted for engagement with a seat 23, as clearly shown in Figs. 1 and 2, the same being adapted, when in engagement with said seat, to shut ofi' the supply of fuel to the generator.

Secured to the inner end of the valve 21 and extending coaxially therewith is a rod or stem 24 hexagonal in form which snugly fits the passage 25 through the generator. With this arrangement it will be seen that the passage through the generator will be divided into aplurality of smaller passages segmental in cross-section which register with the faces or sides of the member 24, it being clear that the edges of said member 24 engaging against the sides of the passage 25 result in this division. The formation of a plurality of narrow passages through the generator, results in the division of the fuel introduced into the generator into as many thin streams ,which of course may be more readily heated than one solid stream, vthereby facilitating the generating process. This arrangement is further of advantage in that the passage through the generator, with this construction, will be continually tions to this kind of an iron.

it will be seen that detachment operation or rotation of Upon rotation of the valve the member 24 will rub against'the sides of the passage 25 and thereby effect dislodging of any particles or carbon which might otherwise clog said passage, the clogging of the passage through the generator of a sad-iron of this nature, through carbon-` ization, being one of the lgreatest objec- VVth the present construction this objection will be overcome and without any extraieffort on the part of the operator, the cleaning being cleaned through the valve. edges of the done simultaneously with the operation of Y the valve. The member 24 may be cleaned occasionally by removing the Vvalve 21,"said member 24 being carried thereby. The inember 24 is of such a length as to project through the discharge vorifice of the generator, when the valveis in closed position in order to dislodge any foreign matter which might clog said orifice.Y The outer end of said member 24 however does not seat against the contracted end'of the passage 25, the latter that uponv closing which is left in therefrom.

of the valve 21 any fuel said passage may escape The upper side of the body 1 is closed by a cover 26 which is provided with a suitable handle 27. Said cover is releasably locked to the body 1, at its front end, by means of lingers 28 provided at the under side of said coverwhich engage notches 29 provided in the upper edges of the lateral walls of said body. A depending lug 30 provided at-theV front end of the cover 26 is adapted to fit snugly in the vertex of the iron between the lateral walls thereof to prevent relative lateral movement of the cover when in opera,- tive position. The rearward end of said cover is secured in position by means of a thumb screw 31 which is threaded in one of the lateral walls of the body 1, the head of said screw engaging a notch 32 provided in the adjacent end of the cover. The edge of the notch 32 and the base portion of the head of screw 31 are beveled so as to insure a snug engagement and conduce to a secure fastening of the cover to the body. A lug 33 provided at the rearward end of the cover is adapted to engage against the rearwall of the body l to prevent movement of the cover in one direction, lateral movement thereof in theopposite direction being of course prevented by screw 31. With this arrangement of the cover may be effected upon retraction of the screw 31.

Provided at the underside of the cover 26 is a transversely arched., deflector plate 34 which is spaced slightly from said cover as clearly shown in Figs. 1 and 3. The plate 34 serves to deiect the heated gases arising from the burner through lateral ventilation always remaining open soV openings which are provided at the opposite sides of the iron by cutting away the upper edge portions of the lateral walls of the body l, thereby serving to prevent heating of the handle 27. By spacing the deflector plate 34 from the cover, cool air may circulate between said parts from one side of the iron to the other and thus serve in a sense to insulate the handle from the heated portion of the iron.

A sad-iron of the construction set forth will be found effectual in use, the same may be readily cleaned and may be manufactured at a low cost.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:
