Specification of Letters Patent.

Patented Feb. 16, 1915..

Application filed April 22, 1913. Serial No. 762,953.

To all whom it may concern Be it known that we, WILLIAM WALLACE KEMP and WILLIAM H. VAN HORN, citi- Zens of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Burners for Gas SingeingMachines, of which the following is a specification.

This invention relates to gas using machines, more particularly to machines of the rotary type for singeing hosiery, and has for an object to provide an improved burner for such machines which may be automatically controlled by the operation of the machines.

Previously in machines of this type the flame has been burned continuously, needlessly heating the adjacent parts of the machine when the flame is not in actual use and causing waste of the fuel supplying the flame. In this type of machine the articles are fed to the flame intermittently, a considerable space of time elapsing between the feeding of the articles, and it is the object of the present invention to prevent the waste of the fuel supplying the flame during this lapse of time between the application of the articles to the flame.

In carrying out this object, the invention comprises, broadly, a valve controlling the supply of fuel to the flame, and means 0perated by the movable parts of the machine for opening and closing the valve so as to completely extinguish the flame or turn the flame down between the feeding of the articles so that no appreciable heat will be generated by the flame when not in actual use and the supply of fuel will be cut down to a minimum.

Another object of this invention is to provide the machine with operating means which may be adjusted to turn on or raise the flame at any desired point of the operation of the machine, and tokeep the flame burning as long as desired to accommodate the machine toarticles requiring different times of exposure to the flame.

Other objects and advantages of this invention will appear from the following detail description of one embodiment of this invention, and from the accompanying drawings in'which Figure 1 is a side elevation of a conventional form of rotary singeing machine having the improved burner applied thereto. Fig. 2 is an elevation of the burner showing in section the adjacent parts of the singeing machine supporting the burner. Fig.- 3 is a detail enlarged sectional view of the singeing machine on the line 83 of Fig. 2. Fig. 4 is a top plan view of the enlarged section of Fig. 3. Fig. 5 is a detailed enlarged longitudinal sectional view through the valve of the burner.

As illustrated in the present drawing the improved burner is applied to a rotary singeing machine adapted particularly to hosiery, and in the general illustration of this singeing machine designates the frame in which is mounted a transverse shaft 11 upon which is secured a relatively large gear-wheel 12 driven in any suitable manner so as to rotate the shaft 11. Also mounted upon the shaft 11 is a spider 13, shown as having three radially extending arms upon the outer ends of which are mounted supports 14 curved in the arc of a circle the center of which is the shaft 11. It will be noted that a considerable space is provided between the supports 14 to admit of the application of articles to be singed. The frame 10 is provided with a superstructure 15 carrying at one side an inclined support 16 upon which are mounted the burner tubes 17. These burner tubes 17 may be mounted upon the support 16 in any suitable manner and are shown in the present instance as being grouped in pairs and carried upon Ts 18. The Ts 18 extend through suitable openings in the support 16 and the tubes extend inwardly in the formation of yokes open at their inner ends for the reception of the supports 14, which are offset laterally from the arms of the spider 13. The superstructure 15, for the purpose of reinforcement of the same, is provided intermediate its ends with a web 19 provided with a horizontal flange 20 turned oupowardly from the web 19 toreinforce the we The burner of this invention, and as disclosed in the present drawings, comprises a valve casing 21 provided upon its inner side with a stud 22 fitting in a socket 23 detachably mounted on the support 16 of the superstructure and arranged below the burner tubes 17. For the purpose of securing the valve casing 21- at the desired angle a set screw 24: is threaded through one side of the socket for engagement with the stud 22 so as to hold the same from turning after the valve casing has been adjusted. A stem 25 is mounted in the valve casing 21 for longitudinal movement therein, and is normally depressed by a spring 26 surrounding the upper end of the stem 25 and hearing at its lower end against the outer side of a valve 27 mounted on the stem and being compressed against the valve by a cap 28 detachably secured upon the upper end of the easing 21. As shown in detail in Fig. 5 the cap 28 is provided with an upstanding hollow projection registering with the stem 25 and adapted to receive the upper end thereof when the stem is raised against the tension of the spring 26. In one side of the casing 21, and above the valve 27, is a gas inlet nipple 29 adapted for connection with a suitable source of gas supply. The casing 21 is reduced in diameter immediately below the valve 27 to provide therefor a seat 30 whereby the supply of gas through the nipple 29 is cut off by the seating of the valve 27 from the lower part of the casing 21. In the two-pipe valve disclosed in the present drawing the lower end of the casing 21 is I provided at one side with a nipple 31 adapted for attachment to a suitable source of compressed air supply and the casing is provided with an internal annular shoulder or flange 32 immediately above the nipple 31 and into which a plug valve 33, mounted upon the stem 25 and spaced below the valve 27, is adapted to snugly fit to close ofi the supply of air to the middle portion of the casing 21. The casing 21 is provided with a third nipple 34, leading from a point intermediate the valves 27 and 33, to which is secured a supply pipe 35 extending to the Ts 18 of the burner tubes. The stem 25 preferably extends but a short distance below the casing 21 and is provided on its lower end with a coupling sleeve 36 secured tothe stem 25 in the usual manner by a set screw and adapted to receive in its lower end a valve operating rod 37.

A detachable bracket 38 is secured to the superstructure 15 in any suitable manner, such as by constructing the bracket 38 U-shape whereby to engage the bracket over the horizontal flange 20 of the superstructure and mounting a plurality of setscr ews 39 in the under side of the bracket for engagement against the lower side of the flange 20 to thus secure the bracket to the web 19. Rising from the bracket 38 is a lug 40 upon which is mounted for rotatable adjustment, by means of a clamping screw 41, a guiding sleeve 42 receiving the lower end of the valve operating rod 37 and admitting of the longitudinal sliding movement of the rod 37 therethrough. A second lug 43 rises from the bracket 38 in spaced relation to the lug 40, and is provided with a bearing in its upper end receiving therethrough a stubshaft 44. The stub-shaft 44 projects through the superstructure 15 and carries upon its outer end a valve rod lifter 45 provided upon its inner end with a sleeve engaging the stub-shaft 44 and adjustably fixed thereon by a set-screw 46. The outer end of the lifter 45 is flattened as shown and bears against the lower end of the valve operating rod 37 which projects slightly below the guiding sleeve 42.

The inner end of the stub-shaft 44 has fixed thereon, by a set screw 47, an arm 48 upon the outer end of which is mounted a roller 49 adapted for engagement with a cam hereinafter fully described. Secured against the outer side of the gear-wheel 12, which turns with the supports 14, is a cam wheel 50 preferably made up of a number of parts, shown as in two parts, whereby the cam wheel 50 may be placed around the shaft 11 without removing the shaft from the frame 10.

From Fig. 3 of the drawings it will be noted that the cam wheel 50 is made up of two semi-circular parts, each of which is provided at its ends with inwardly extending lugs 51, the lugs at the meeting ends of the sections of the wheel abutting and being secured together by clamping screws 52. The wheel 50 is provided at points opposite to the spokes of the gear-wheel 12 with clamps 53, the same being shown as comprising straps one of each clamp being secured to the wheel 50 while the opposite strap of each clamp is secured across the inner side of the adjacent spoke by means of the clamping screws 54. In this manner the wheel 50 is rigidly secured upon the gear 12 and moves therewith. The periphery of the Wheel 50 is smooth and is concentric to the shaft 11 and supports the rollers 49 in normal inactive position whereby the valve operating rod 37 remains at rest under the tension of the spring 26. The wheel 50 is provided at points opposite to the supports 14 with cam blocks 55 having inclined ends, as at 56, up over which the roller 49 rides as the cam wheel 50 is turned and the blocks 55 are brought into register with the roller. Each cam block 55 raises the roller and holds the roller in such raised position during the time occupied in the passage of a predetermined length of the corresponding support 14 between the burner tubes 17. The cam block 55 is of such a length that it supports the roller until the desired length of the support 14 passes from between the burner tubes 17.

The articles to be singed are of different lengths, and in order to accommodate the machine to these different length articles, and to economize the consumption of fuel, the cam blocks 55 are supplemented with supplemental blocks 57 which inter-fit with the cam blocks 55 and provide a continuation thereof. For the purpose of securing the blocks 55 and 57 upon the cam wheel 50 the blocks are provided with pairs of spaced and inwardly extending lugs 58 straddling the rim of the wheel 50 and having screwthreaded openings therethrough for the reception of set-screws 59 adapted to extend inwardly through the lugs 58 and engage against the inclined shoulder 60v on the side of the wheel 50. The wheel 50 is provided with the shoulder 60 on each side so that the set-screws 59 which are carried in the opposed lugs have a substantial support for holding the blocks 55' and 57 to the wheel. The blocks 55, which are of considerable length are provided with two or more pairs of the lugs 58 so as to substantially support the blocks upon the wheels. It is understood that there are a number of the blocks 55 on the Wheel 50, corresponding to the number of the supports 14 on the spider, so that the valve is opened each time that a support 14 is brought into the. operative path of the flame issuing from the burner tubes 17 In the operation of the burner the gear wheel 12 is rotated by any suitable means whereby the shaft 11 is turned and effects the turning of the spider 13. As the gear wheel 12 is rotated the cam wheel 50 is carried therewith and the roller 49 rides freely over the periphery of the cam wheel 50. When one of the work supports 14 reaches the burner tubes 17 one of the cam blocks 55 engages the roller and lifts the same from the periphery of the wheel. As the roller is lifted the arm 48 is raised, the stub-shaft 44 is turned, and the lifter 45 is moved up against the lower end of the supporting sleeve 42, lifting the valve operating rod 37 against the tension of the spring 26. When the rod 37 is raised the stem 25 moves therewith and lifts the valves 27 and 33 from the seat 30 and flange 32 respectively, whereby gas is admitted to the nipple 34, and compressed air is admitted to the nipple 34:. The gas and air commingle and pass through the supply pipe 35 to the Ts 18 from which this gaseous mixture is distributed to the several burner tubes 17 where it is ignited from a pilot 17 The pilot 17*, as may be seen from Fig. 2 of the drawings, comprises one or more small tips located immediately above the lower burner tubes 17 and supplied continuously with gas from the common gas supply pipe 29 by a branch pipe 17 leading from the supply pipe 29 forwardly of the main burner supply valve 21. Thus the pilot takes its gas from the main pipe 29 before the gas passes through the valve 21 and a steady flame is thereby maintained at the pilot 17. It is of course understood that this is only one of many arrangements of pilots that may be used, the present disclosure being merely for the purpose of clearly illustrating the present invention. The valve is held in this open po- Sition until the cam block 55, or the supplemental blocks 57 pass from beneath the roller 49. When the blocks pass from beneath the roller, the roller is permitted to. drop down upon the periphery of the wheel 50 wherebv the lifter 45 drops into normal position and the rod 37 is released. The spring 26 forces the valves 27 and 33 closed so that the fuel supply is cut off to the burners and the small pilot 17 a alone re-.

mains burning.

The structure of the valve 21 may be other than shown in the drawings, since this valve forms no part of this invention except as being of a construction adaptable for use connection with the automatic controlling means. Thus the valve may have any number of openings, may be made to supply gas from any suitable source to the burner tubes and may be different in construction. It is also understood that this invention is not limited to the specific construction herein described, and shown, but this structure may be varied to accommodate the burner to machines of different forms and of a different character than singeing. machines, the scope of the invention being determined by the appended claims.
