MAKE-Am CLEANER FOR INTERNAL-COMBUQTIGN-MOTOR ENGW Application filed February 27, 19%. Serial No. 6%,525.

To all whom it may concern:

Be it known that I, JACOB TRIPLER WAIN- WRIGHT, a citizen of the United States, residing at Detroit, in the county of Wa e and State of Michigan, have invente a new and useful Intake-Air Cleaner for Internal-Combustion-Motor Engines, of which the following is a specification.

-By my invention I provide means that may be conveniently installed on any of the usual types of this kind of engine and for manipulating an intake flow or current of a mixture of dirt and air in a way to eject therefrom much of such dirt or solid particles of matter because, they act as an abrasive to injure the interior parts of. the

engine; also, means to [utilize intake-sud,

7 removal that has not, been attained in the prior' state of the art under such exacting requirements.

In a conventional manner, a preferable way of applying my invention is shown in Figures 1 and 2 of the accompanying drawing. Figure 1 represents a sectional-elevation at BB on. Figure 2, and Figure 2 represents a sectional-elevation at AA on Figure 1.

In both of these figures; identical referencenumbers identify and refer to parts thatiare identical, or are duplicated.

At 3 and 4, arerepresented the sides of an enclosure or box having a bottom at 5 from which it may be disconnected and rec- The succession of arrows show the progressive stages and turns which the current is caused to take between the curved conduit walls shown at 8 and the afore-mentioned straight conduit walls shown at 6. The intake to the apparatus is shown at 9,

and the outlet is shown at 10.

It may be remarked that in Figure 2 where the intake 9 is shown, it is convenient to locate the outlet 10 also thereat in that view and consequently it is not shown separately in that view.

It will be perceived that Figure 2 shows that the space between conduit walls 6 is more constricted at the top than at the bottom. This feature as it obtains between the corresponding curved conduit walls 8 causes a corresponding fluctuation (rise and fall) of the velocity of the current and thereby creates and imposes means for causing separation and removal of dirt which are more efficient than would obtain without such changeable constriction, and the thus created efliciency is proportionate to the corresponding rate at which such c0nstriction changes. This feature of my invention is purpcsed to impose under conditions which minimize turbulence, a successional series of recuperations of velocity to the current and consequent corresponding recuperations of momentum to the particles of dirt floating therein, and alternate such recuperations with progression at falling velocity, and thereby rovide means to alternately impart muc momentum to the inertia-impelled self-ejecting particles of dirt; and during such ejectmcnt, to correspondingl lessen the velocity and turbulence of t e gaseous portion of the current thereat and thereby lessen the resistance to and consequently facilitate the progress of such inertia impelled particles of dirt through and out of the thus quieted gaseous portion of the current. It will'be perceived that efficiency of the device is dependent also upon thenumber of such treatments that are comprised in the successional series through which the stream is progressed.

It will be perceived that, the combination of features thus described is more eficient in producing desired results than, was ever attained in the prior state of the art.

I claim:

A conduit adapted to progressively conduct a stream of dirty air through a sums sion of alternating turns respectively in contrary directions, and constructed in a way to constitute means to impose alternate decreasing and increasing stream-velocity intervening respectively between such alter-- nating turns in such progression, and constructed 111 a Way to constitute means toenable self-impelled ejectment of dirt from the stream during such progression through turns which follow a corresponding decreasing stream-velocitya'nd precede a corresponding increasing stream-velocity.
