l SAD-IRON..

Specification of Letters Patent.

Application filed. J une 29, 1912. Serial N o. 706,603.

To all whom it may concern Be it known that I, FRANK WV. ROSENGREN,

a resident of Chicago, in the county of Cook and State of Illinois, have invented certain `new and useful Improvements in Sad-Irons,

of which the following is a full, clear, and

. exact description.`

` y yieldingly pressed into contact with the material beingironed or pressed. In practice, it has been found that this yielding connection causes even pressure and is also less tiring upon the operator.

A further object of the invention is to provide an improved connection between the pipe for supplying fuel to the chamber in the iron, and the body of the iron. In practice, these tubes are usually formed of thin metal, suchf as brass. An exceptionally heavy tube has been found to result in imperfect combustion at the outlets of the pipe and therefore, it is desirable to avoid the use of a pipe having a thick surrounding wall. l/Vhen a thin pipe is used and it becomes heated to a high degree, it is liable to break in use, and for this reason, the invention provides improved means for securing the pipe to the body of the iron so that there will be no stresses upon the pipe while the iron is hot and in use.

Another object of the invention is to provide means whereby the iron may be adapted for use in heating a vessel or article placed on the body of the iron.

The invention further designs to provide a sad iron of improved construction and operation. y

The invention consists inthe several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. y f p In the drawings Figure 1 is a view, partly in longitudinal section and partly in elevation, of a sad iron embodying the invention. Fig. 2 is a top plan view. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a detail view of the cut-off sleeve.

The body 1() of the iron has a combustionchamber 11 therein, to which fuel is conducted by a pipe 12 which extends lengthwise through thecenter of chamber 11. At

the outside of the body of the iron, pipe 12 is provided with a valve 13 of usual construction, for regulating the supply of gas, and a coupling or nipple 1L adapted to be connected to a flexible hose so that gas will be supplied to the sad iron as it is being moved about. Within chamber 11, pipe 12 1s provided, at its underside with slits 15 Patented Oct. 27, 19111:.

through which the fuelescapes from pipe 12, for ignition. As a result, combustion will occur adjacent the bottom of body 10 when the bottom is to be kept hot. At one end, pipe 12 extends through the end wall "1G of body 10, and a screw 17 extends through a. hole in pipe 12 to rigidly secure the pipe to one end of body 12.

at one end of body 10 and a screw 20 extends through the pipe and through a plug 2l fitted into the end of the pipe, and into the bottom of lug 19.` As a result of rigidly .seeming both ends of pipe 12 in the body of the sadiron, there will be no stresses or strains applied to the burner portion, or that portion of thepipe in the body 10 which becomes hot iu use and therefore all danger of breaking the pipe is avoided. Pipe 12, outside of the iron does not become so hot as to warrant danger of breakage. Holes 22 are formed in sides of body 10 adjacent the bottom 10L to supply air for combustion to chamber 11. Ribs 23 are formed on bottom of bottom 10 between the holes 22. Side walls 10b are formed with openings 24 for admittingair adjacent the cover 25 which extends over the combustion chamber 11 and said cover is removably connected to body 10 by a headed screw 2G which is adapted to hold the slotted front end of cover 25 and a latch 27 whichis pivoted to a screw 28 which is secured in the body. This latch may be turned intoposition indicated in dotted lines Fig. 2, so that it will be disposed over the slot 29 in cover 25 to permit the cover to be removed.

A handle 30 is secured to a loop 31 which is formed of a stripof metal, to elevate the grip-portion of the handle above the top of the sad iron. Loop 31 is secured, by screws 32, to the upper member of a resilient U-shaped strip 33 which has its lower member secured by screws 34 to the cover 25, and a strip of asbestos or heat insulatingmaterial 311 is interposed between the strip and the cover, so that the heat from the com- The other end of` pipe 12 fits into a seat 1S formed in a lug19 bustion chamber will not be readily trans-'- mitted to the handle. This strip 83 is formed of a heavy strip of metal and a stopscrew 36 is secured in the upper member of strip 33, extends through the other memrestricted to the details set forth, since these may be modified within the scope of the ap- -pended claims without departing from .spirit and scope of the invention.

ber of the strip, the insulating strip 349 and cover 25, and has a head 37 which limits the upward movement of the upper arm of strip 83. Screw 36 also prevents lateral movement of the handle relatively to the top of the sad iron. The resilient strip and' stop thus provide a yieldingor resilient connection between the handle and the iron which serves as a cushion whereby yeven pressure will result, and the pressing operation will be rendered more easy forl the op-v erator. It will be observed that this yielding connection is so constructed that the iron can be manipulated laterally or forwardly and backwardly the same as if a rigid connection were applied. In other words, the yielding connection is such, that the iron may be positively operated in any direction but permits yielding only in that direction in which pressure is exerted to force the iron into contact with the material being pressed or ironed.

The device is adapted to be used as asadiron and also as a heater for a vessel or article placed upon the body. For this purpose, burner-pipe 12 is provided, in addition to the series of slits 15 which direct the fuel downwardly, with a series of slits or openings 152L which are disposed to direct thefuel upwardly. A cut-0E sleeve or valve A() is rotatably held on pipe 12 and extends between a wall 16 and lug `19 so that it will be, held against longitudinal movement on the pipe 12. rllhis sleeve is partly cut-'away and can be turned to bring the cut-away into position to permit the fuel to escape downwardly through slits 15 and close slits 15a or into position to close slits 15 and permit the escape oi3 fuel through the slits 15a. A stop-pin l1 limits the movement of the sleeve between its alternative positions. A stud Llf2 is iiXed to one end of sleeve AOso that it can be readily turned. As a result of this con,- struction, the device may be used as a' sadiron and by removing cover 25 and the handle secured thereto, and rotating sleeve 40 to cut o the escape of fuel through slits 15 and to open the slits 15a, the iiame will be article which may be placed upon body 10.

In this manner, the improved device may be used for a number of different purposes.

The invention is not to be understood as i the Having thus described the invention, what I claim as new and desire to secure by Letters Patent', is:
