Be it known that I, ARTHUR H. NEWTON,

AETHI'IR' NEWTON, OF NEW YORK, N. Y.-

FUEL-MIXING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

'a citizen of the United States, residing at 173 l VestEighty-th'ird street, New York,-

in the county of New York and State of New York, have invented certain new and useful Improvements in Fuel-Mixing Devices for Internal-Combustion Engines, of

which the following is a specification.

Thisinvention relates to fuel-mixing deticularly -of.'the type designed for insertion within the intake-pipe of the engine, and

having an annular flange or collar held between thefnieeting-fla-nges of the c'arbureter and manifold. a

Attempts have been heretofore made to devise a mixer. of this type having blades,

. efficient; one that will be sufliciently subcomplete and therefore uniform mixing of stationary or rotatable, for imparting a whirling movement to the mixture of gaso:

lene and air after it leaves the carbureter, screens of various sorts being sometimes employed to assist in. the mixing of the fuel. Most of these, however, ifnot all, have been for one reason or another unsuccessful, and

none of them so far as I know hasattained sufficient success to warrant adoption by any of the leading makers of automobiles, in which a device of this character is particularly useful. p

The object of the present invention is to produce a mixer of the aforementioned type, economical of manufacture and yet highly stantial to withstand any back-firing and therefore protect the .carbureter, and yet so constructed as to allow passage therethrough the air and gas before passing into the cylinders. I

The invention is illustrated in the accom- .panying drawing, wherein,-'-

Figure-l is a side elevation of a preferred form of, mixer; Fig. 2 1s a vertlca lsectional view of the same, the rotatable vane and its spindle, however, bemg shown in 'elevat1on;

slightly modified in shape.

As illustrated, the mixer comprises a casting or shell 1, preferably of brass, having.

an annular upright portion 2, and an aperscreen "8, preferably of brass.

tured base 3 constituting the bottom of the device and conveniently formed of crossbars 4 (see Fig. 3). The base 3 is provided with an annular flange or collar 5 by means of which the mixer may be held in' the intake passage, the flange 5 being secured be: tween the meeting-flanges of the carbureter and the manifold,not shown: Extending vertically upward from the base or spider formed by thecross-bars ei, and integral therewith if the shell is cast, as is preferred, there is a bearing 6, preferably somewhat elongated, as shown.

Over the shell 1', and secured theret along its lower edge preferablyby a clamping-ring .7, there is a relatively fine-mesh The upper, outer edge of the portion 2 may be cut away to accommodate the lower edge ofthe screen and its clamping-ring. 7, as shown, the arrangement being such that the outer face of'the ring 7 liessubstantially flush with the outer surface of the upright portion 2 of the shell. The screen is dome-shaped and preferably, as shown in Figs 1 and 2, substantially hemispherical, it halving been found that screens having such shapes are noticeably more rigid. and stronger,- and therefore better able to withstand back-fir.-

ing strains than screens of other shapes. A

screen 8 shaped as shown in Fig. 6 may be used with good results, but is not quite so strong as that illustrated in Figs. 1 and 2.

.A spindle Ois mounted for easy rotation in the elongated bearing (3, and is provided at its upper end, beyond the bearing, with a propeller 10, the several blades of which extend outwardly to within a short distance of the shell 1. The lower end of the spindle may' be provided with a nut or other head 11. f f Within the casing 1 and its screencover 8, and -so formed as to lie loosely against the inner surfaces thereof, there is a Wire 0011 12, the height of which, when the parts are assembled, is substantially that of theinside of thecasing and its screen-top.

The use of the device will be apparent.

The shell or casing is slid upinto the intakepipe of the engine preferably where the .carbin-eter-flange abuts the same, the flange 5 of thepnixer being securely held between.

the neeting-flanges of the carburetor and the manifold As the .mixture of air'and hydrocarbon passes into the shell of the mixer, it is diyided by the spider 4: into several portions which, upon further forward movement impinge upon the blades of the propeller and cause the latter to rotate quite rapidly in a well-known manner, the mixture becoming Well broken up and part thereof being thrown outward against the wire coil 12 and the casing and there further broken up and mixed. The portion of the mixture which passes upward throughthe blades of the propeller strikes the wire coil Q12 and immediatelyv thereafter the wirescreen 8 both of these elements assisting materially in the mixing of the ingredients of the charge.

The coil 12'not only assists in the mixing operation, as above described,=but serveslikewise, due perhaps to any movement it may receive from the impact of the fuel in passing thereby, to kee the inner surface of the casing clean and ree from any foreign accumulations whatsoever. After use, it has beenobserved that both the inner wall of the shell and the wire coil are clean and bright. The wire coil also serves as a reinforcement 25. 'of the screen-top-8, assisting the latter to ,withstand any reverse shocks due to backfiring.

' With the use of a device of this construction, a very thorough mixingof the air and gas 1s effected, in proper proportions, viz.,

three parts air to one part of gasolene', without materially impeding the flow to the cylinders, and a great saving of gasolene is realized. Since, as is well known, back-firing is frequently due to improper mixing of the air and hydrocarbon, it will be appreciated that the device of the present invention I will prove of considerable advantage in the elimination of this evil. Carbon deposits in 40 the cylinders due to use of low-grade gasolene, or faulty mixing, or accumulationof dust, dirt, etc., will also be prevented.

I I claim 1. A fuel-mixing device for internal combustion engines, comprisinga casing having an annular upright portion for lnsertlon 1n the intake-plpe of the englne and a flanged,

apertured support forming the bottom of the device; a central bearin in said support; a

, rotatable spindle journa led in said bearing with said casing; and a wire coil Within the cap and casing and lying thereagainst.

3. A fuel-mixing device for internal combustion engines, comprising a casting havingan annular upright portion for insertion in the intake-pipe'of the engine, a flanged,;

apertured support formingv the bottom of the device and a central bearing in said sup-'. ,port; a rotatable'spindle journaled inj'said bearing blades on said spindle; a substantially hemispherical screen .cap, having a. flush connection along its equatorial line with saidcasting; and a wire coil within the cap and casting and lying thereagainst.

Intestimony whereof I aflix my signature in presence of two witnesses. v
