To all whom it may concern Be it known that we, WILLIAM W. KEM and WILLIAM H. VAN HORN, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Adjustable Singeing-Burners, of which the following is a specification.

This invention relates to an improved gas burner, particularly to the singeing type; and has for an ob]ect to provide a burner for the singeing of cloth and the like, and to provide a construction of burner wherein the line of flame may be regulated as to length to correspond to the width of the cloth being singed.

Another important object of this invention is to provide a burner built up of'the desired number of units to correspond to the length desired; and to provide means for independently and separatelycontrolling the units so as to close ofi' or control the gas supply thereto and thus regulate the length of the flame of the burner.

The invention further aims at a construction of burner wherein the same may be used in multiple, each having its separate units, and to provide operating means, connecting the respective units of the several burners whereby the same may be controlled independently of the other connected units of the burner. By this arrangement it is designed to simultaneously control the length of the flame of a plurality of burners so as to offset the unnecessary heating of rolls and other parts of the singeing machine above the burners, and to also economize in the consumption of fuel.

In the present preferred embodiment of the invention which is hereinafter described in detail, the above and other objects and advantages will be clearly described and pointed out, the present embodiment being disclosed in the accompanying drawings wherein,

Figure l is a top plan- View of a row of the improved burners, showing the connecting means for their respective units to control the same simultaneously. Fig. 2 is an end elevation of the row of burners of Fig. 1 showing the connecting means. Fig. 3 is a longitudinal section through one of the improved burners. Fig. 4: is a side elevation of a slightly modified form of the burner. Fig. 5 is an end view of a number of the modified burners showing the connecting means applied thereto.

1th reference to these drawings, wherein like parts are designated by similar characters of reference throughout the several views, and particularly to Figs. 2 and 3, it will be noted that the improved burner comprises a mam supply pipe 10 extending from end to end of the burner, and having at each end a threaded portion 11.

Mounted upon the supply pipe 10 are a number of burner units disclosed in the present instance as in the form of sleeves, the main or central one of which, designated as 12, being mounted upon the intermediate portion of the supply pipe 10 in spaced relation thereabout, and communicating with the supply pipe 10 through openings 13 formed in the supply pipe. The units 12 may be of any desired length, and is preferably of a length equal to the smallest width of cloth, or the like, to be singed; for during the operation of the burner the central unit is adapted to supply the gas at all times to the burner tips 1 1 mounted thereon.

Abutting the opposite ends of the units 12, and abutting one another, are disposed pluralities of relatively small units 15 and 16, each comprising a sleeve held in spaced relation about the sup ly pipe 10 by collars, or packing glands 1 The glands 17 are fitted into a counterbore'in the outer end of each unit, 15 and 16, and held against the shoulder 18 in the end of each unit by the reduced end 19 of the next adjacent unit which fits into the counterbore and seals the joint between the units. Each unit 15 is provided with one or more burner tips 20 communicating with the annular gas receiving chamber within the unit between the supply pipe 10, the inner wall of the sleeve, and the glands 17. The units 16 are in a like manner provided with burner tips 21 opening into the gas chamber therein. The gas chambers of the units 15 and 16 communicate independently with the supply pipe '10 only through branch pipes 22, one end of each of which is tapped into the side of the unit 15 or 16, while their opposite ends pass through the side of said unit and are tapped into the side of the supply pipe 10.

A valve 23 of any preferred construction is interposed in each branch pipe 22 and is adapted to control the flow .of-gas there-. through from the supply plpe 10 to the respective unit. l

For each unit 15 and 16there is provided an independent branch 22, each branch having its independent valve 23, and the valves 23 are controlled by independent arms 24.

' hen, as'shown in Figs. 1 and 2, a plurality of burners are employed, such as five burners, the burners are arranged in suitably spaced relation longitudinally of the web to be singed, the respective units 15 and 16 of the burners being in longitudinal alinement and having their respective valve operating arms 24 in longitudinal registration with one another.

The arms 24 preferably extend down and are forked or bifurcated, as at 25, at their outer ends, for the reception of a connecting link or lever 26. The lever 26 extends beneath the row of burners and is pivotally secured to the registering arms 24 to operate the respective valves 23 simultaneously and control the flow of gas to the respective units 15 and 16. It is, of course, understood that for each set of units 15 and 16, there is a separate lever 26 so that the respective sets of units of the burners may be independently controlled. By this arrangement it is thus seen that should the width of-the cloth passing over the burners be less than the lengths of the burners the outer units. 16, at each. end of the burners, may be cut off from the gas supply by the operation of the outer lever 26 which will limit the flame to the burner tips 14 of the main unit or section 12, and the" burner tips 20 of the units 15 adjacent the main section. It is of course understood that any number of units 15 and 16 may be mounted upon the supply pipe 10, the latter being of sufl'icient length to receive the desired number of units.

The means employed for holding the units 12, 15 and 16 in assembled relation upon the supply pipe 10, and also for connecting one end of the supply pipe 10 to the service or gas feeding pipe, and for closin 'the opposite end thereof, comprises caps 2 and 28. The cap 27 is suitably threaded at its outer end, as at 29, for engagement with the service or gas feeding pipe, while its inner end is reduced in diameter to engage in a counterbore in the outer unit 16. The cap 27 is also internally threaded to receive the adjacent threaded end 11 of the supply pipe. This construction is disclosed to advantage in Fig. 3 of the drawings, and wherein it Will be seen that the cap 27 holds the end units 16 from displacement from the supply pipe 10 and also forms a connection between the supply pipe and a service pipe. The op osite'cap 28 is similar in form to I the cap 2 with the exception that instead of being externally threaded and having athrough passage therein,,the cap 28 has a closed outer end wall 30 closing the outer end of the burner. The cap 28 abuts the outermost unit 16 on the outer end of the burner in a manner similar to the engagement of the cap 27 with the inner end section 16, and retains the units 15 and 16 from displacement from the supply pipe 10. The supply pipe 10 is of such a length that when the caps 27 and 28 are tightened thereon, the caps force the units 12, 15 and 16 together and seal "the abutting ends thereof to form the separate annular gas chambers about the supply ipe.

In Figs. 4 and 5 o the drawing is disclosed one modification of the above described burner, and wherein it will be noted that the gas supply tube 10 is connected to the service pipe by a cap 27 in the form of a coupling member, and that the pipe 10 is closed at its outer end by a cap 28*. At one side of the supply pipe 10, and preferably above the same, are arranged a plurality of burner sections or units 12, 15 and 16. These burner units are assembled by reducing the ends thereof and counterboring their opposite ends so as to interfit and form a tight joint when assembled. The partitions or glands 17 are used to separate the various units one from the other. The various units are independently connected to the supply pipe 10 by branches 22 which are tapped in the supply pipe 10 at one end, and tapped into the respective units attheir opposite ends. The branches 22 are provided with valves 23 and arms 24, as in the preferred form, and are adapted to be actuated by the lever 26 pivoted to the forks 25 of the arms 24, as above described. The units 12, 15 and. 16 are respectively provided with the burner tips 14:, 20 and 21.

The operation of this modified form is identical with the operation of the preferred form for when the end valves 23 are closed gas is cut off from the outer end units 16 and is admitted to the inner units 15 and 12 only. The unit 12 is preferably in constant communication with the supply pipe 10 by the branch pipe 13 extending between 'the supply pipe and the main section 12.

It 1s of course understood that it is within the spirit of the present invention to make various other changes or modifications in the above described constructions, within the scope of the following claims, and that the burner of the present invention may be used not only for singeing cloth, but also for other uses to which the present burner may be advantageously applied.
