Specification of Letters Patent.

Application led January 11, 1909. Serial No. 471,618.

To all whom 'it may concern:

Be it known that I, CLARENCE E. SAF- FonD, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Sad-Iron, of which the following isa specication.

My invention relates to that class of sad irons in which gas is burned between two smoothing faces of the ironing-body, and its object is to provide a device of this kind in which the smoothing-faces may be easily kept at the desired temperature, and which shall utilize a maximum of the heat units in the gas.

My invention consists in a sad-iron having a revoluble ironing-body provided with two smoothing-faces, in combination with a novel burner so constructed that there will be maximum space above the burner, and having the ironing-body provided with tapering sockets to receive tapering trunnions on the handle.

It further consists in the novel details especially set forth in the claims and shown in the accompanying drawings, in which- Figures 1, 2, and 3 are side, front and rear elevations of my improved sad iron. Fig. 4 is a vertical central cross section of the same. Fig. 5 is a cross section on the line 5 5 of Fig. 4. Fig. 6 is a cross section of the burner. Fig. 7 is a cross section of the fuel mixer. A

Similar reference characters refer to like parts throughout the several views.

The ironing-body of my improved sadiron is pro-vided with two parallel opposed smoothing-faces 1 connected by a wall 2, having slots or perforations 3, the rear end being formed with a tapering socket 4 to receive one trunnion on the handle, and the front end being formed with a tapering socket 5 to receive the other trunnion on the handle, and with notches 6 to receive the lower end of the locking lever. The handle is formed by a cross piece 8, preferably of wood, and front and rear arms 9 and 10 which are secured to the cross piece by means of the screw 11. The lower end of the front arm 9 is in the form of a vtapering trunnion 12 adapted to iit the socket 5. This arm 9 is provided with a longitudinal slot, in which is mounted the locking lever 13 on the pin 17, the inner end or finger 14 -of which is adapted to engage in either notch in the front of the ironing body to position the same. The upper end may be provided with a button 15, and the finger the flat spring 16. Thislinger 14` is tapering with fiat sides. This insures positive locking of the ironing body on the handle, preventing all vibration. The notches 6 have fiat sides and the wedging action of the linger 14 under the action of the spring 16 renders the union of the parts practically rigid.

The rear arm 10 of the handle is formed hollow, and with a connection 19 to which a flexible gas-tube may be attached. The trunnion 20, formed on this arm fits the tapering socket 4 in the rear of the ironingbody. Extending downward from the trunnion, then horizontally and then upwardly is the burner tube 22, formed with transverse slots 23 `and downwardly inclined holes 24 to permit the escape of gas. A threaded rod 25 projects througha hole in the trunnion 12, and is provided with jamnuts 26 whereby the trunnions 12 and 20 can be positioned and the bearings of the ironing-body on the handle accurately adjusted. The front end of the burner tube 22 is entirely free in the socket 5. This permits the tapering trunnions to be accurately adjusted without interference by the burner tube.

The tubular part 28 of the rear arm 10 of thehandle is provided with an enlargement into which is secured a sleeve 29, which isv threaded for the needle-valve stem 30. A stuiiing box gland 31 insures a tight joint. In line with the sleeve 29 is mounted a second sleeve 32 having its bore 33 formed to fit the point of the stem 30. The flow of gas is regulated by turning this stem.

Because of the inclination of the stem 30 and the sleeves 29 and 32, the jet of gas will strike the center of the restricted portion 35 of the bore of the tube 22. The gas entering this restricted passage draws with it a supply of air through the funnel 36, in the manner usual to the Bunsen burner. This restriction also prevents back-Hash. Owing to the depression of the tube 22, maximum of space is obtained above the burner tube. Openings 38 at the rear end of the body admit air to fully and properly Patented Mar. 8, 1910.

14 is normally held in locking position by consume the gas. The small holes 24; direct. and a gas mixing-valve mounted on the hanjets of burning gas downward and out-iH ward, and thus thoroughly and eifeetually expelling the burned gases, that have hitherto prevented proper combustion, through the openings 3. They also cause good circulation of air above the slots 23. Air freely enters through the openings 38 in the rear wall and to some extent through the upper ends of the openings 3 in the sides.

The chief advantages of this sad iron are, that it provides for greater combustion space above the burner in proportion to the distance between the faces, the upper surface of the burner tube being at or below the center line of the trunnions, that it insures speedy removal of the burned gases, that a proper mixture is supplied to the burner, and that the ironing-body is properly and adjustably journaled on the handle. The handle may be made of any suitable nonconducting substance. Because of the free circulation of air caused by the jets from the small holes 24, there is no gas unconsumed, perfect combustion being insured by a full supply of air and indicated by the peculiar humming sound which can be noticed when burners of this type are acting properly.

I-Iaving now explained my improvements what I claim as my invention and desire to secure by Letters Patent is l. In a sad iron, the combination of an ironing body having parallel smoothingfaees connected by slotted walls and having bearing rings in its ends, a handle having trunnions to enter said rings, a burner tube connected at its ends to said trunnions and bent between its ends so its upper surface is in the center line of the trunnions, and a gas mixing valve to direct the fuel gas down the rear bend of the burner tube.

2. In a sad iron, the combination of an ironing body having parallel smoothingfaces connected by walls having slots and tapering sockets, a handle having tapering trunnions to fit said sockets on which trunnions said body is revoluble, a burner tube extending through said body and connected at its rear end to the handle, a bolt extending from the front end of the burner tube and through the front trunnion, and nuts on said bolt whereby the trunnions may be adjusted relative to the ironing-body.

3. In a sad-iron, the combination of an ironing-body having parallel smoothingfaces connected by perforated walls, a handle having trunnions whereon said body is revoluble, a burner tube extending through said body between the trunnions and provided with openings for the escape of gas, the tube being bent downward at the trunnions and having its upper edge in the center line of the trunnions, the bore of said tube being restricted at the rear trunnion,

4. In a sad-iron, the combination of an ironing-body having parallel smoothingfaces connected by apertured walls having sockets at the rear and front ends, a handle comprising a cross bar and arms mortised and secured into the ends thereof so as to nextend parallel to each other, a burner tube united to the lower end of one of the arms, and an adjustable connection between the opposite end of the tube and the other arm to hold the parts in parallel alinement the middle portion of the burner-tube being eccentric to the bearings.

5. In a sad-iron, the combination of an having parallel smoothingfaces connectedby apertured walls and having bearing rings at the ends, a handle having trunnions to enter the rings, and a burner tube extending between the trunnions and having downwardly inclined openings for gas jets whereby the burned gases are expelled through the apertures in the walls, the middle portion of the burner-tube being eccentric to the bearings.
