- This invention relates to 'a radiant heat flame compression burner for singeing textiles. TeX- tiles have previously been singed very effectively according to the method and apparatus shown in Patent No. 1,862,960. It has been found that certain modifications in the burner there illustrated permit a greater speed of the fabric and a much improved singeing of the fabric.
- the fabric in this invention is drawn across the burner in the direction of the arrow and in contact with the two water cooled edges which serve to properly distance the fabric from the refractory surface. Between these cooled edges are placed refractory bricks and from one of the edges a flame from a perfectly proportioned fuel and air mixture plays on the fabric and is deflected by the fabric against the refractory surface, heating this surface.
- the temperature of the surface is controlled by the volume of fuel and airy mixture burned; the amount of such mixture burned is determined by the speed at which the cloth travels and the extent to which the singeing is to be carried on. When the singeing is thorough and the cloth velocity high the fuel consumption is such as to produce an incandescence on the refractory surface.
- This incandescent surface in contact with the flame helps to maintain the flame at the maximum temperatures. It is the high temperatures of llame compressed between the cloth and the refractory surface which is so effective in singeing, and the compression is greater because of the wedge shape of the area between the refractory bed and the cloth, and the travel of the cloth pulls the flame toward the small end of that area.
- the radiant heat assists the singeing eect and adds to the effectiveness of the flame, the interacting effect of both factors accounting for the high eiciency of this device.
- This burner has extreme flexibility, is capable Aof producing a maximum singeing at high speeds on such fabrics as twills, drills and insulator cloth; at the same time by turning on to less extent it is spectacularly suited for singeing rayons, acetates and even such light fabrics as voile.

Kemp Manufacturing Company, Baltimore, Md., a corporation of Maryland Applicationjanuary 26, 1945, serial No. 574,796
11 Claims.
This invention relates to 'a radiant heat flame compression burner for singeing textiles. TeX- tiles have previously been singed very effectively according to the method and apparatus shown in Patent No. 1,862,960. It has been found that certain modifications in the burner there illustrated permit a greater speed of the fabric and a much improved singeing of the fabric.
The fabric in this invention is drawn across the burner in the direction of the arrow and in contact with the two water cooled edges which serve to properly distance the fabric from the refractory surface. Between these cooled edges are placed refractory bricks and from one of the edges a flame from a perfectly proportioned fuel and air mixture plays on the fabric and is deflected by the fabric against the refractory surface, heating this surface. The temperature of the surface is controlled by the volume of fuel and airy mixture burned; the amount of such mixture burned is determined by the speed at which the cloth travels and the extent to which the singeing is to be carried on. When the singeing is thorough and the cloth velocity high the fuel consumption is such as to produce an incandescence on the refractory surface. This incandescent surface in contact with the flame helps to maintain the flame at the maximum temperatures. It is the high temperatures of llame compressed between the cloth and the refractory surface which is so effective in singeing, and the compression is greater because of the wedge shape of the area between the refractory bed and the cloth, and the travel of the cloth pulls the flame toward the small end of that area. The radiant heat assists the singeing eect and adds to the effectiveness of the flame, the interacting effect of both factors accounting for the high eiciency of this device. This burner has extreme flexibility, is capable Aof producing a maximum singeing at high speeds on such fabrics as twills, drills and insulator cloth; at the same time by turning on to less extent it is splendidly suited for singeing rayons, acetates and even such light fabrics as voile. Two burners are generally used on any singeing machine, one burner for each side of the fabric.
Other objects and advantages of the invention will be apparent from the following description and the accompanying drawings forming a part hereof and in which:
Figure 1 is a top yplan view of the burner.
Figure 2 is a front elevational view thereof.
Figure 3 is a top plan view of the lower casting.
Figure 4 is a cross sectional view on line ll--4 of Figure 2. l
Figure 5 is a partial longitudinal sectional view on line 5-5 of Figure 4. y
In the drawings similar numerals refer to similar parts in the several views.
I between 'the twomembers.
The top burner portion 3 has burner orifices 6 projecting substantially at an angle of 45 to the cloth. A completely combustible mixture-of fuel and air is fed to. these orifices through the chambers I and 8'. After striking the cloth the llame travels parallel with it and is compressed between the cloth and the refractory surface, being drawn into the wedge shaped area partly by the cloth in its travel, and compressed against the cloth because of the shape of that area. The top burner portion is attached by means of bolts 9 to the lower burner portion I0, which is a triangular tubular member receiving a completely combustible mixture of air and fuel from one or both ends through pipes II. The triangular, tubular member has at the bottom thereof a plurality of valves I2 which when open admit the combustible mixture to the chamber 8; These chambers are formed in the lower vcasting I 0 and the top burner portion 3 and in the latter partitions I3 divide the chambers from each other and fromthe central chamber 'I'. The central chamber 1 is fed through openings I 4 in the top of the triangular section I0.
The top burner portion 3 and the rectangular tubular member 4 have water passages I5 and I6 therein and connections with the water feed Il, which passes the water first to passage liiand then through pipe I8 to passage I5 with an exit at I9.
The tops of the top burner portion 3 and the rectangular tubular member 4 are roundedA as shown at 20 and 2| and over these rounded shoulders the cloth or fabric passes at a rapid rate which can attain 500 yards per minute.
The valves I2 are opened or closed depending upon the width of the fabric being singed. The chamber I is substantially the length of the smallest width of fabric that it may `be desired to singe. The completely combustible mixture is ignited at the burner orices 6 and the flame is projected outwardly between the fabric and the refractory material or fire brick. The cloth and the shoulders on both sides of the re brick retain the flame in the compartment thus formed and force it down upon the lire brick which is heated to an intense white heat and radiates that heat to the fabric to singe the same completely at the rapid rate of passage of the fabric across the burner.
The cooling chambers on both sides of the refractory material keep the shoulders or edges of the burner cool. Theame is completely cutv off from following the fabric by these projecting edges 20 and 2|, edge 2l may be said to wipe the flame from the qfabric.l vThe spent gases escape from the ends of the burner at the edges of the fabric.
It will be seen that the burner of this invention holds the fabric the required distance from the incandescent radiating elements and a close regulation of the flame is permitted by the valves admitting the combustible mixture to the burner so that control of the extent of 'singe is always obtainable.
It will be apparent that many modifications may be made in the burner without departing from the invention as defined in the appended claims..
