GAS-IGNITING APPLIANCE.

SPEGIFICATION forming part of Letters Patent No. 760,937, dated May 24, 1904.

' Application filed September 21, 1903. Serial No. 173,994. (No model.)

To all whom it may concern:

Be it known that we, DOUGLAS TAYLOR and WALTER MARTIN TAYLOR, residents of the city of Toronto, in the county of York and Province of Ontario, Canada, have jointly invented certain new and useful Improvements in Gas-Igniting Appliances; and we hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a gas-igniter for that class of gas-burning appliances in which the gas-burners are arranged in a cluster or group and provided with a continuously-burning gas-igniting flame opposed to one of the burners or located between two adjacent burners to ignite the gas as it issues from them when the cut-off valve has been actuated to open the gas-supply to the cluster or group. In this class of gas-igniting appliances the remaining burners of the cluster or group depend for'ignition upon the explosion caused by the outflowing gas coming into contact with the flame of the primarily-ignited burner or burners, such explosions not only producing unpleasant reports of greater or lesser degrees of loudness, but also frequently causing considerable damage, particularly by shattering the globes and the incandescent mantles with which the burners'may be fitted. To obviate these explosions when igniting the burner cluster or group is the object of the present invention, which is accomplished by employing an igniting appliance having flameapertures opposed to all the burner-tips and a flame-slot forming a means of communication between the flame-apertures to enable the ignition of the gas at any part of the igniting appliance to instantaneously ignite the gas at all of the flame-apertures and maintain an igniting-flame opposite each burner to ignite the gas as it reaches the burner-tips'when the cut-off valve has been actuated to admit the gas to the burner cluster or group.

The invention may be carried into practice by connecting the burners to a common burner base or head fitted with a cut-off valve between its inlet and outlet ports and providing the burner cluster or group with a cluster-igniter located in juxtaposition to the burner-tips and connected with the burner- 5 burner-base between the cut-off valve and the inlet-port being fitted with a tube extending to the cluster-igniter to maintain a continuous flame to instantaneously ignite the gas as it issues from the cluster-igniter.

The cluster-igniter instead of being con- -nected to the burner-base between the cut-off valve and the outlet-ports may be connected to the burner-base between the inlet-port and the cut-off valve, or it may be connected to the gas-supply pipe at any convenient point. In 5 all of these cases it is necessary to provide the cluster-igniter with its own cut-off valve and open it in advance of the cut-0E valve for the burner-base, so that the cluster-igniter will become charged with gas and ignited by the 7 continuous flame to prepare for the ignition of the gas as it reaches the burner-tips when the burner cluster or group has been charged by the opening of the cutoff valve controlling the supply from the gas source to the burners,

the cut-01f valve of the cluster-igniter being closed to extinguish the igniter-flames when the gas issuing from all of the burner-tips of the cluster or group is ignited. v

For an understanding of the invention we have hereinafter described and have shown in the accompanying drawings the means above referred to of carrying the foregoing object into practice; but as it is possible to attain the same results by several other modi- 5 fications of a cluster-igniter arranged in the same relative position to the burner-tips we do not wish the invention to be confined to, the specific means described and shown.

In the drawings, Figure .1 is a perspective 9 view of a burner cluster or group fitted with incandescent mantles, showing the cluster-igniting appliance. Fig. 2 is a similar view of a modification of the cluster-igniting appliance. Fig. 3 is a perspective view of the cluster-igniter. Fig. 4 is a view of the tube for the cluster-igniter. Fig. 5 is a sectional view of the cluster-igniter and tube. Fig. 6 is a perspective view of a second modification, and

Fig. 7 is a sectional view of the cut-off valve. Like letters of reference refer to like parts throughout the specification and drawings.

Connected to a pendent gas-pipe a is a burnerbase Z), consisting of a valve body or casing having at its lower end horizontal arms 0,fitted with adjustable valves (Z to regulate the volume of gas passing to the burners a. As shown in Figs. 1 and 2 of the drawings, the burners e are connected to the horizonal arms cand are grouped or clustered around the valve body or casing 5 to occupy as small a space as possible; but they may, if so desired, be arranged in a straight row, as shown in Fig. 6, and formed in the lower ends of the burners e are apertures I through which air is admitted to mix with the gas as it passes to the burner-tips Z.

Within the valve body or casing b is the cutoff valve m, located between the inlet-port m and the outlet-ports 0' to control the flow of gas from the gas-supply source to the gasburners, and connected to the valve body or casing?) between the cut-off valve m and the gas-pipe a is a gas-tube 0, the tip of which is in sulbstantially the same plane as the bu rnertips ter-igniterp, which in the construction shown in Fig. 1 is connected with the valve body or casing 6 between the cut-off valve m and the outlet-port 0 by a gas-tube q, through which the gas may pass to the cluster-igniter when the cut-off valve on is being opened to allow of the gas passing from the gas-pipe a to the gas-burners e. In the cluster-igniter p are a series of flame-apertures 9', opposed to the burner-tips Z, and connecting the flame-apertures 1" is a diminutive flame-slot 8, through which a small leakage may occur when the cluster-igniter is charged with gas. A continuous flame is maintained at the tip of the gas-tube 0 by the constant flow of gas from the gas-pipe to ignite the gas as it issues from the cluster-igniter at a point opposite the tip of the gas-tube 0. The gas ignited at this point travels instantaneously, by means of the diminutive slot, to all of the flame-apertures a, which, being opposed to the tips of the gasburners,cause the simultaneous ignition of the gas at the burner-tips immediately after the opening of the cut-off valve of the cluster or group.

In the construction shown in Figs. 1 and 6 the cut-off valvem is so arranged in the valve casing or body that it will open the gas-supply to the cluster-igniter to permit of its ignition before fully opening the passage to the gas-burners, so that the cluster-igniter can instantaneously ignite the gas as it issuesfrom the burner-tips. As shown in Fig. 2, it is possible to connect the gas-tube q with the gas-pipe a and fit it with the cut-off valve t, which may be opened in advance'of the opening of the cut-off valve m to allow of the clus- Opposed to the burner-tips Z is a cluster-igniter being ignited in advance of the charging of the burners and which may be closed to cut off. the supply of gas to the cluster-igniter when all the burners of the cluster orgroup have been ignited to economize as far as possible the use of the gas by prevent-- ing its unnecessary consumption by the eluster-igniter. Projecting upwardly from each burner-tip Z is a mantle-supporter u, and suspended from each mantle-supporter a is an incandescent mantle 'u.

Heretofore the means provided to ignite the gas-burners was a continuous flame at the tip of the gas-tube 0, which was opposed to one of the gas-burners or located between two adjacent burners, so that when the cutoff valve had been actuated to charge the gasbnrners the continuous flame ignited the gas issuing from the burner or burners adjacent to it, the remaining burners of the group or cluster depending upon the'globe being filled with gas and ignited by the ignited burner or burners, the ignition of which caused an explosion of the gas and often resulted in the shattering of the incandescent mantles and occasionally in the breaking of the globe.
