MARTIN G. HIGGINS, OF .IPITTSBURGH, PENNSYLVANIA, ASSIGNOR T0 PITTSBURGH GAGE & SUPPLY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

GAS BURNER FOR IRONING MACHINES.

To all whom it may concern.

Be it known that I, MARTIN Gr. Hreorns, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State 01'' Pennsylvania, have invented a new and useful Improvement in Gas Burners for Ironing Machines, of which the followinnis a specification.

The invention relates to ironing machines, particularly those adapted for domestic use and which comprise a gasdieated ironing shoe and a rotatable padded roll adjacent to the shoe.

The object of the invention is to provide such ironing machines with an improved gas burner so that the shoe may be uniformly heated from end to end, and also to provide an improved burner which may be readily substituted in place of the burners now in use in ironing machines.

The invention is illustrated in the acconipanying sheet of drawings of which Fig. 1 is a rear elevation of the upper portion of an ironing machine, part of the outer casing or hood of the shoe being broken away to show the burner; Fig. 2 a horizontal central. sectional view through the burner; and Fig. 3, a vertical sectional view to enlarged scale taken on the line TIL-III, Figv l.

The ironing machine shown herein is typical of the general construction and arrangement ot a number of machines now on the market. It comprises a frame 1 which supports a padded roll 2 and an ironing shoe 3, the roll being adapted to be rotated by means of a motor, not shown, and the shoe being adapted to be heated by a gas burner arranged adjacent to the ironing wall of the shoe. The shoe is provided with end portions 7 and 7 and with a cover 8, and the frame also supports a feeding table l and a receiving table Articles to be ironed. are fed upon the roll 2 from the table l and are moved by the roll into contact with the shoe. After passing between the roll and shoe the articles drop upon the receiving table 5, either completely ironed or in a convenient position to be readily passed again between the roll and the shoe.

To uniformly heat the shoe from end to end, there is provided a burner pipe having a gas inlet at one end and gas outlets adjacent to the shoe. The pipe is closed at a point adjacent to its inlet end and a bypass conduit extends from a point between the gas inlet and the closed portion of the pipe to substantially the center of the burner portion of the pipe so that the supply of gas may flow equally in both directions from the center of such burner portion towards its ends.

The burner pipe may be an ordinary gas pipe (3 supported at its ends by the end portions 7 and 7 of the shoe 3. The outer end of the pipe 6 may be provided with a valvecontrolled or other type of inlet 17, whereby connection may be made to a con duit 9 leading; from asource of gas supply. Preferably, the closing of the outer end of the pipe 6 is ellected as indicated by a plug 10 at a point close to and 'nside of the end 7 of the shoe. The bypass conduit may also be gas pipe 11 closed at its ends and provided adjacent to such ends with lateral openings 1% and 13. These openings register, respectively, with openings 1% and 15 formed in the pipe 6, the openings 15 being substantially at the center of the burner portion of the pipe. A. convenient and etitective way of attaching: the lay-pass conduit Ill to the pipe 6 is by forming a weld connection as indicated at 16 in Fig. 3.

By providing the ironing machine with a burner such as shown herein and just ex plained, gas for heating the ironing shoe flows through the by-pass conduit 11 to the center of the pipe 6 and then flows outwardly towards each end of the burner por tion of such pipe, with the result that the shoe becomes uniformly heated. By arrang ing the by-pass conduit entirely within the ends '7 and 7 of the shoe, as well as within the cover 8, ironing machines which are in use and which have the usual form. of single pipe burners may be provided. with the improved lnirner without altering the openings in the hood, and without providing additional openings. To substitute the new for an old type or burner, it is only necessary to remove the hood 8 from the ironing shoe, and then to slip the new burner into openings of the shoe ends 7 and; 7 used for attaching the old type of burner.

Accord ng to the provisions of the patent statutes, I have described the principle ant operation of my invention together with the construction which I now con. to represent the best embodiment thereof. However,

I desire to have it understood that, within the scope of the appended claims, the invention may be practiced by other forms of con struction than that particularly illustrated and described herein.

1 claim:

1. A. gas burner for heating the shoe of a domestic ironing machine comprising a pipe closed at one end and having a gas inlet at its other end, and lateral gas inlets intermediate of its ends, said pipe being closed near its inlet end, and a lay-pass conduit extending "from said pipe at a point bet-ween its inlet and closed portion to substantially the center of the burner portion of the pipe.

2. A gas burner for heating the shoe of a domestic ironing machine comprising a, pipe closed at one end and having a gas inlet at its other end, a plug in said pipe adjacent to its inlet end, and a lay-pass conduit extending from said pipe at a point between its inlet and said plug to substantially the center of the burner portion of the pipe.

In testimony whereof, I have hereunto set my hand.

MAR-TIN G, HIGGINS.
