CHARLES A. BEACH, OF NEW YOEK, N. Y.

SAD-IRON.

To all whom it may concern:

Be itknown that 1, CHARLES A. BEACH, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a new and 1111- proved Sad-Tron, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved heating structure for sad-irons which may utilize at the will of the operator a plurality of sources of heat supplying fuel.

A further object of the invention is the arrangement in a sad-iron of heating means formed to utilize a supply of gas and air furnished from either end of the iron.

A still further object of the invention is the arrangement of improved burners for sad irons designed to utilize or burn a mixture of air and gas supplied from a suitable supply pipe or tube, and also for utiliz ing gas and air supplied from an ordinary Bunsen mixer, these means supplying the fuel being used at different times.

In carrying out the objects of the invention a heater is provided for a sad-iron formed for permitting a single flame to be projected across the iron, the flame being supplied with fuel from a suitable source and led into the iron at one end. A. second supply of fuel is led into the iron at the opposite end and connected with the heater in such a manner as to be directed in a plurality of jets toward the surface to be heated. Suitable piping and valves are provided so that either supply of fuel may be used at any time, one supply being passed in at one end of the iron, and the other supply being passed in at the opposite end.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference in dicate corresponding parts in all the views.

Figure 1 is a side view of an iron embodying the invention; Fig. 2 is a longitudinal vertical section through Fig. 1; and Fig. 3 is a bottom plan view of the heater arranged in an iron. Fig. 4 is a sectional vieW through Fig. 1 approximately on line 44:.

Referring to the accompanying drawings by numerals, 1 indicates the body of an iron with a bottom portion 2, a heat shield 3, and a handle 4t. The heat shield 3 is Specification of Letters Patent.

spaced from the upper part of the body 1, but rigidly connected thereto by securing means extending into lugs 4. The lugs a space the shield 8 above the top of the iron for protecting the hand of the operator and also accommodating a pipe hereinafter fully described.

The body 1 is formed hollow for accommodating burners 6 and 7. The burners 6 and 7 are shown integral, which is the pre ferred form, but it will be evident that the same may be made separate and connected together if desired by suitable interlocking lugs or other means. The burner 7 is formed with a bore 8 having a lateral extension 9 for directing fuel, as for instance air and gas, into the space 10. A screen of wire mesh 11 is provided in the usual man- 'ner for preventing, or assisting in preventing, the backfiring of the gas. The flames from the burners are deflected by plate 21 so as to heat the bottom 2. The burner 7 is fitted in the front end ofthe body 1 of the iron and is adapted to receive a pipe 13, which in turn is connected with an elbow 14L threaded on to the pipe 5. The pipe 5 is provided with a valve 15 so as to control the air and gas from a pipe or tube 16 when the same is fitted over the pipe 17 and the valve 18 is closed. The pipe or tube 16 is preferably flexible so as to permit a free movement of the iron and is connected with a suitable supply of compressed air and gas for providing a proper mixture for supporting' combustion when the mixture escapes through the screen 11.

The burner 6 is preferably cast integral with the burner7, but may be made independent thereof. This burner is provided with a substantially annular bore 19 communicating with a plurality of discharge apertures 20. A central web or deflecting member21 is provided so as to deflect the heat generated by the burners 6 and 7 in order that the same may properly heat the bottom 2 of the iron. It will of course be evident that although the major'por'tion of the heat is maintained adjacent bottom 2, some of the heat and the products of combus tion may pass out suitable openings in the iron, as for instance openings 3. The products of combustion passing from space 10 may pass upwardly through any desired space, as for instance the space between the side walls of the iron and the burner 6. The

products of combustion are preferably re duced to a minimum as it is designed to supply a comparatively large quantity of an to as possible under the circumstances.

it will be evident that the end door 23 could be made independent of the burner 6, but

by having the door formed integral therewith, as shown, which the preferred structure, and having the burner 7 formed integral with the burner 6, the pipe 13 will hold both of the burners and door 23 in position. To positively prevent any movement of the door 23 or associated parts, a pivotally mounted locking member 24 is provided which is designed to bear against the door when the iron is in use. Threaded into the enlargement 22 and in free communication with the bore 19 is a pipe 25 connected with an ordinary Bunsen mixer 26. It will be understood that any kind of a mixer 26 may be used which will draw in air with the pure gas being used for mixing air therewith sutliciently for supporting combustion in the space or chamber 10. The mixer 26 is sup plied with gas from the pipe 27 which is connected with a tube 28. The tube 28 is in free communication with the pipe 17 so that when the Valve 15 is closed and the flexible tube or pipe 28 is connected with pipe 17, is supplied. to the mixer 26, the valve 18 being open. By manipulating the valves 15 and 1S, and the tubes 16 and 28, a mixture of air and gas may be used, or the pure gas may be used. It will also be noted that a supply of fuel is provided at each end of the iron. The substitution of pipes 16 and 27, and the means for permitting this substitution, is of great advantage as in many institutions which use the automatic heating iron it is desired to use the iron after the ordinary power for supplying compressed air for pipe 16 has been turned oft. When this power has been turned oil and consequently no air can be supplied to pipe 16 for mixing with the gas therein, the burner 7 will not operate as there is not suliicicnt air in the chamber 10 to support comlmstion und or these circumstances. Then this occurs, the pure gas is turned on to pipe 27 and the Bunsen mixer 26 will cause a proper mixture to be forced into the iron and to distribute it through the apertures 20.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a self-heating sad-iron, a body portion, a pair of burners arranged in said body portion connected together, one of said burners being formed with a baflle for the burners and the second burner acting as a support for the burner formed with the bafie, a supply nipple or pipe and independently controlled connectors between said pipe and the burners.

2. In a self rhea-ting sad iron, a body portion, a pair of burners arranged in said body portion, a supply pipe, means connected to said supply pipe for directing air and gas under pressure to one of said burners, and a second means connected to said supply pipe for directing gas and air to the other of said burners, said last mentioned means including a Bunsen mixer, said last men tioned burner being provided with a battling member for confining the heat from both of said burners to a position near the bottom of said body portion.

3. In a self-heatin sad-iron, a body portion, a pair of independent burners arranged in said body portion, said burners belng arranged at opposite ends of said body portion, a supply pipe, means connected to said supply pipe'for directing air and gas under pressure to one of said burners. and means connected to said supply pipe including a Bunsen mixer for supplying a combustible mixture to the other of said burners, the latter burner being provided with a central deflecting web designed to deflect the flame from said burners toward the bottom of said body portion.

4. In a self-heating sad iron, a body portion, a pair of burners arranged in said body portion rigidly secured together, one of said burners being formed so as to direct a blaze therefrom substantially parallel to the bottom of said body portion, a deflecting web or ba-flie secured to the other of said burners for deflecting the flame from both of the burners in order to retain the same adjacent the bottom of said body portion, and independent means for sumalying a combustible mixture to said burners.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
