This invention relates to a gas mixer and more particularly to a device of this character adapted to be fitted into the main supply pipe of a gas stove or the like and by means of which a whirling motion may be imparted to gas as it passes through the supply pipe. One object of the invention is to so form the attachment that it may easily fitted into the supply pipe of a gas stove and not only cause a whirling motion to be imparted to the gas but also cause the gas to pass from the attachment in the form of a spray and there by prevent moisture from lagging in the gas p1 e. V

llnother object of the invention is to provide the tubular body of the attachment with a spiral deflector extending longitudinally through it which will always assume the proper position in the body when thrust into it and which may be easily removed when clean-' ing is necessary.

The invention is illustrated in. the accompanying drawings, wherein Figure 1 1s a longitud'nal sectional view '5 showing the attachment set in place within a main supply pipe of a gas stove.

Fig. 2 is a perspective view of the improved gas mixer, and

Fig. 3 is an enlarged view looking at one end of the attachment.

This improved gas mixer is intended to be fitted into the main supply pipe 1 of a gas stove and consists of a tubular casing 2 having a spiral deflector 3 fitted therein. The tubular casing is preferably formed of sheet metal and for the greater portion of its length is of an even diameter but has its forward end portion tapered to form a nozzle 4 terminating in a spout 5 which is crimped inward- 1y, as clearly, shown in Figures 2 and 3, to provide the spout with a reduced outlet 6. By referring to these figures, it will be seen that the outlet is formed with extensions 7 disposed in radiating relation to the axis of the casing and, therefore, gas will be discharged from the nozzle in the form of flat streams which whirl through the pipe 1 in diverging relation to each other but eventually mixed as they move through the pipe. This whirling motion causes a partial vacuum to be formed in the pipe about the nozzle and creates a s'rong suction which serves to prevent moisture from hanging back in the pipe. The rear end portion of the tubular casing is flared outwardly to form a circum- 'ferentially extending flange 8 which bears against the walls of the pipe 1, as clearly shown in Figure 1, and since the casing is formed of sheet metal it will have suflicient resiliency to cause the flange to fit snugly against the walls of the pipe and thereby .re-. tain the casing in its proper position within the pipe and also prevent gas from passing through the pipe without passing through the attachment. The deflector 3 consists of a strip of flatmetal which is twisted to asthe rear end of the nozzle and the deflector will be retained in its proper position within the casing.

When the attachment is in use, the coupling 9 which connects the main pipe 1 of the gas stove with its supply pipe 10 is loosened in order to release the pipe 1 from the pipe 10 and the device is thrust inwardly through the open end of the main pipe until it assumes the position shown in Figure 1. The coupling is again tightened and as gas passes from the pipe 10 through the pipe 1 this gas will passthrough the attachment. A whirling motion is imparted to the gas by the deflector 3 and the whirling gas then passes sume a spiral formation and this strip is of through the nozzle 4 and out through the out- This causes a partial nozzle and moisture contained in the gas will be prevented from lagging as the gaspasses through the main pipe to the burners of a stove. WVhen it is necessary to clean the attachment, the coupling 9 is released and the device can be easily drawn outwardly after which the spiral deflector Will be Withdrawn from the tubular body. The body and deflectolfeaii'thed be easily cleaned and after being a'sembled replaced inth'e Pipe.
