HYDRGGARBON MOTOR.

Application tiled November 17, 1917. Serial No. 202,677.

To all whom t may concern Be it known that I, DONALD II. REEVES, a citizen of the United States, and resident of Detroit, Wayne County, State of Michigan, have invented certain new and useful Improvements in- IIydrocarbon'"^l?vlotors, of which the following is a specification.

This invention relates to hydrocarbon motors and particularly to means for supplying clean air thereto.

In the'use of motor vehicles, particularly for truck and tractor purposes, some difficulty is experienced in connection with the motor because of dust laden air beiiigtaken in through the carbureter. It is one of the objects of the present invention to separa-te the dust from the air which is being drawn4 into the carbureter.

`Another object of the invention is to provide a tortuous passage for the air drawn into the carburetor of a hydrocarbon motor together with means for catching and removing from the air the dust particles drawn in with it. f

Another object of the invention is to provide a tortuous passage for the air entering the carbureter of of a hydrocarbon motor together with means for withdrawing dust from said chamber by ejector action.

Other objects of the invention will appear from the following description taken in connection with the drawings which form a part of this specification, and in which:

Fig. 1 is a plan view of a hydrocarbon motor embodying the invention;

Fig. 2 is a side elevation of the motor illustrated in Fig. 1;

Fig. 3 is an enlarged sectional view of the dust separating device shown in connection with the motor illustrated in Figs. 1 and 2;

Fig. 4 is an end view of the dust collector shown in Figure 3 and disconnected from the exhaust pipe sleeve;

Fig. 5 is a view similar 'to Fig. 3, illustrating another torni ot dust collector.

Referring to the drawings, 10 represents a hydrocarbon motor having a carbureter 11 of any desired construction, and a tan 12 driven through a belt 13 from a moving shaft ot the motor. It will be understood that the carburetor 11 has an air intake opening 111 which in the resent instance is connected to a1 pipe 15 w .ich leads around to operate immediately at the rear of a ra-` diator (not shown in the drawings) and thereby produces a current of air passing rearwardly over the motor.

An exhaust pipe 16 is 'shown in the drawings as arranged at the side of the motor opposite the carbureter side and a sleeve 17 partly surrounding and separated somewhat from the exhaust pipe has its interior connected with a tube 18 which leads to a chamber 19 connected to the pipe 15, above referred to. By this arrangement the air supplied to the intake 14 of the carbureter through the sleeve 17, tube 18, chamber 19 and pipe 15 is warmed somewhat bv passing over a part of the heated exhaust pipe 16.

The chamber 19 is shown in longitudinal section inFig. 3 and it will be seenv that it is provided with an inlet opening 2O at one end and a-n outlet opening 2.1 at the other end, both of which openings are inthe upper part of the chamber. The inlet opening is connected to the tube 18 and the outlet opening tothe pipe `15, and the passage 22 through the chamber between these openings is a tortuous one, being interrupted by battles 23 which extend somewhat.` intothe curved parts 24 of the passage.

The lower part of the chamber 19 has a secondary inlet opening 25 at the opposite end of the chamber from the inlet opening 20 and beneath the outlet opening 21, and there is a secondary outlet opening 26 at the opposite end of the chamber from the outlet opening 21 and beneath the inlet opening 20. Between these openings 25 and 26 there is formed a substantially direct passage 27, which passage is connected at several points with the-tortueus passage 22 by transverse passages 28. These passages 28 preferably open into the passage 22 adjacent the respective battles 23, and they are shown as curved and as making an acute angle with the passage 27 at their junction with said latter passage.

The inlet opening 25 is connected by a pipe 29 with a funnel-shaped device 30 opening forwardly and arranged iinmediatelv at the rear of the Jtan 12, above referred to, and the outlet opening 26 is connected to a pipe CFI 31 which leads to a point beneath the motor Where it is open to the atmosphere underneath the vehicle.

By this arrangement of passages and piping it will be seen that when the motor 1s running and the fan 12 is therefore 1n operation a current of air is caused to pass into` the funnel 30 through the pipe 29 and opening 25 into and through the passage 27 and out of the chamber through the outlet opening 26 and pipe 31. rlhere 1s practically nothing to retard this current of air because of the substantially direct arrangement of thepassage 2T. llt will also be seen that by the operation of the motor air Will be drawn into the. carbureter through the pipe 15, chamber 19 and sleeve 17. As this air passes through the tortuous assage 22 of the chamber the particles o dust carried by 1t will strike against the various bailles 23 and be directed downwardly into the passages 28. The greater part of the air Will of course be carried on through the passage 22 to the outlet 21 and pipe 15, but a small portion of it with the greater portion of the dust will flow into the passages 28 and by the ejector action of the current of air passing through the passage 27 will be drawn into the. latter passage and carried od through the opening 26 and pipe 31. Thus the air passing to the pipe 15 and consequently to the carbureter 11 Will be freed of part or all of the dust which Was combined with it as it enteredthe sleeve 1T.

ln Fig. 5 the pipe 15, exhaust pipe 16, and sleeve 17 are the same as in Fig. 3, but the chamber 19", while it has a tortuous passage 22. with inlet and outlet openings 2() and 21 respectively, as well as battles 23, yet it is formed with a somewhat different dust collecting lower portion. lln this form of the invention the passages 28a which are formed adjacent the battles 23 open downwardly into a catch-basin 27a Which contains a quantity of oil or other liquid, as shown. The basin 27a is also formed with' partitions 28 which extend downwardly from the respective ballles 23. By this arrangement it will be understood that the air entering the inlet opening 2O impinges against the bandes 22% which causes the greater part of the dust carried by the air to be deflected downward on the surface of the oil in the several. compartments of the basin 27a., this operation taking place at each one of the turns in the tortuous passage 22. As the air emerges through the outlet opening 21 and through Lacasse the ipe 15 it has had the greater part or all of t e dust separated from it.

llt will be understood further that the basin 27a is detachable from the other part of the chamber, as by removing screws 2T so that the interior of the basin may bet cleaned and oil renewed from time to tim(` lt will be understood further that my invention is not limited to the details of construction shovvn and other forms may be used Without departing from the spirit or sco e of the invention.

aving thus described my invention, what ll claim and desire to secure by Letters Patent is 1. lin a hydrocarbon motor. in combination, a means providing an air intake for a carbureter, an air chamber connected to said intake, a fan, driven by the motor, a conduit leading' from a point adjacent said fan to saidl chamber, and battles in said chamber so arranged as to separate the dust from the air passing to the carbureter intake.

2. lin a hydrocarbon motor, in combination, a means providing an air intake for a carbureter, an air chamber connected to said intake, a fan driven by the motor, a conduit leading1 from a point adjacent said fan to said chamber, and curved baffles arranged crosswise in said chamber to deflect dust from the incoming air downwardly and have it carried away by the air from said conduit.

3. lln combination, a casing, Walls in said casingdefiningI passageways. said passage- Ways including two generally parallel passageways extendingr through said casing. one passageway comprising a plurality of convolutions adapted to separate out material of greater specific gravity than the stream.

and a plurality of cross passages between the parallel passages leaving the convoluted passage at the point where material isv thrown out, said remaining parallel being substantiallyfrce of convolutions. but constricted Where it joins the cross passages to exert an ejector action thereon.

tain combination. a casing. and walls in said easingdefining passages therein includingl a tortuous passage adapted'to separate material by dynamical reaction, cross passages positioned to receive material separated, and a single discharge passage arranged to have an ejector action on all said cross passages.
