GAS-MIXER.

Patented Sept. 24, 1,918.

Continuation of application Serial N o. 122,347, led September 27, 1916.- This application led February 11, 1918. Serial No. 216,517.

To all whom t may concern:

Be it known that I, PERCY MILES SNIDER, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Gas-Mixer, of which the following is a specification.

This invention is embodied in a device which intimately mixes the gases and air that pass from city street gas mains to the stoves, ranges, furnaces or heaters where they are to be burned, and its object is to produce a mixer that will be simple and effective.

This invention consists of a nozzle adapted to give a whirling and intermixing movement to the gases that pass through it, which nozzle is introduced into the conduit that conveys the gases to the place of combustion. It further consists in fitting a 'disk of line wire webbing across the intake end of the nozzle to break up the streams of gases passing to the nozzle.

This application is in part a continuation of my former application No. 122,347, led September'27, 1916.

In the accompanying drawing, Figure 1 is an elevation of a gas meter, gas stove and the pipe connecting them. Fig. 2 is a longitudinal 'section of a pipe union with my improved mixer in position. Fig. 3 is a side elevatiog and Figs. 4 and 5 the two end elevations of this mixer. Fig. 6 is a longitudinal section of a pipe with a slightly modified form of mixer in position;

Similar reference characters refer to like parts throughout the several views. I

Fig. 1 of the drawing shows conventionally a gas stove 1, a gas meter 2 and a pipe 73" connecting them. It will be understood that the stove represents any desired mechanism wherein gas may be burned. A union 4 of well known construction is interposed between the gas measuring and gas consuming devices. This union consists of the usual ends 5 and 6 screwed onto the ends of the pipe 3, and a nut 7 that connects the ends. The adjacent faces of the ends 5 and 6 are flat and between them this novel gas mixing device is mounted.

As shown in the drawing, this device consists of a cylindrical body 9 having a radial flange 10 at one end, the opposite end being tapered to constitute a nozzle 11 and this nozzle being formed with substantially spiral internall grooves 12. A disk 14 of woven wire may be mounted within the cylindrical body 9. A washer 15 of rubber, leather or other desirable material may be employed to secure this mixing device in position. When the mixer is to be positioned intermediate the ends of a length of pipe 17,*the flange 10 will be omitted, as shown in Fig. 6, in which case the body 9 of the mixer should snugly t the interior surface of the pipe in order to hold it in position.

Ordinary city gas is not a single permanent gas but a mixture of gases and usually carries a considerable percentage of air. The probable action of this mixing device is to give to these mixed gases a whirling motion, intimately mixing them so that they will be in perfect condition to burn with the hottest possible flame. The screen 14 breaks up these gases as they How through the mixer. The exact operation of this device is not fully understood, but it has been found by actual practice that the amount of gas required to heat equal quantities of water is much less when this mixer is used than without it.

I claim:

1. In combination with a pipe for conducting gas to a burner, a gas mixer mounted in said pipe and comprising a cylindrical body through which the gas Hows, the discharge end of the body being pipe, a gas miyer mounted in said union and Substantially spiral channels on the inner comprising a cylindrical body through side of the tapering end to cause the gas which the gas flows and having an outpassing through the mixer to revolve and be l0 Wardly extending radial flange at the rethoroughly mixed, and a screen Within the ceiving end adapted to be gripped between body to break up the stream of gas before two parts of the union, the opposite end of it reaches said spiral channels.

the body being tapered and formed with PERCY MILES SNIDER.
