6 Claims.

The device forming the subject matter of this application is an attachment for internal combustion engines, and the invention aims to provide a novel means for affording a supply of heated air, supplemental to the mixture of air and fuel which passes through the carburetor, novel means being provided for mingling the auxiliary air and the mixture from the carbu retor, to produce a fuel for the engine which will result in an increase in the mileage per gallon, and, in generaha greatly improved operation in the engine.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:--

Fig. 1 shows in top plan, a portion of an in-- ternal combustion engine equipped with the de-' vice forming the subject matter of this application;

Fig. 2 is a side elevation of the engine with the attachment applied thereto;

Fig. 3 is a longitudinal section of the mixing mechanism;

Fig. 4 is a transverse section on the line 4-4 of Fig. 3;

Fig. 5 is an edge View of the breaker;

Fig. 6 is an edge View of the discharge member.

Referring especially to Figs. 1 and 2, the numeral 1 marks an internal combustion engine having an intake manifold 2' and an exhaust manifold 3. A pulley 4 is mounted on the fan shaft of the engine.

An air heater 5 extends along theside of the exhaust manifold 3, and is secured thereto, or to any accessible part of the engine, the construction being such that the air proceeding through the heater 5 will be heated from the exhaust manifold 3; On the intake end of the heater 5, there isan air strainer or filter 6, of any desired construction. A choke valve 7 is mounted in the heater 5, closely adjacent to the air strainer 6, and is operated by any suitable mechanism indicated by the numeral 8. The forward end of the heater 5 has a return bend, shown at 9 in Fig. 2. At the rear end of the return bend 9, the sameis connected to a conduit 10 which extends upwardly and forwardly, as shown in Fig. 2. The conduit 10 is united to a connection 11,

which appears best in Fig. 2. In the reduced lower end of the connection 11- there is a butter-.- fly valve 15 (Fig. 2), the shaft of which is marked by the numeral 16, the shaft carrying an arm 17, which, as shown in Fig. 1, is pivoted to an operating member 18 extended rearwardly into the car whereon the internal combustion engine 1 is mounted.

The lower end of the connection 11 is joined to a tubular housing 19, as shown in Figs. 2 and 3, the connection communicating with a cylindrical chamber 21 in the housing, the housing being carried on the engine frame by meansof a bracket 20, or otherwise.

It can be seen in Fig. 3 that in the forward end of the housing 19, an anti-friction bearing 22 is mounted. In this bearing, and in the forward end of the housing, a shaft 23 is journaled for rotation. On the outer end of'the shaft 23 there is a pulley 24 connected by a belt 25 with the pulley 4 on the fan shaft of the engine. Packings 26 may be employed wherever desired. The shaft 23 has a bearing, intermediate its ends, in the intermediate portion of the housing 19, in ad- Vance of the chamber 21. r

A sleeve 27 is keyed to the shaft 23, within the chamber 21, and has a shoulder 28, shown in Fig. 3. The sleeve 27 is surrounded by a plurality of rings 29, having abutment against the shoulder 28, the rings 29 being held together by any desired number of securing elements 31. Fig. 5 shows that the rings 29 have outwardly extended blades 32, which have an inclination, circumferentially of the, rings whereon they are mounted. The blades 32 are thin and resilient, and they vibrate, as the shaft 23 rotates. Noting the places at whichthe numeral 33 is applied in Fig. 3, it will be observed that the periphery of the blades 32 is slightly eccentric with respect to the axis of rotationof the shaft 23. They are, therefore, slightly eccentric, at their outer end, with respect to the cylindrical wall of the charm ber 21.

The rings 29 and their blades 32 constitute an admission rotor, which has an important function in agitating the mixture and in securing the advance thereof toward thebreaker, which will now be described. i

The breaker disk at is securedto the shaft 23 and is located in the chamber 21 immediately to the rear of the admission rotor. disk 34 has transverse openings 35 therethrough, the said openings being located adjacent to the periphery of the breaker disk. The openings 35 preferably are of cylindrical form, but they are The breaker J charged into the connection 11.

funnel-shaped at their ends, as designated by the numeral 36. Slits 3'7 are formed in the periphery of the breaker disk 34. The slits 37 intersect the openings of the breaker disk. The inner edges of the slits 37 slant inwardly and forwardly, as shown at 33 in Fig. 3.

Immediately in front of the breaker disk 34, a discharge member 39 is secured to the shaft 23, and. is held in place by a nut 40 on the said shaft. In its periphery, the discharge member 39 has a plurality of slots 41 defining blades 104, which are inclined circumferentially of the discharge member. breaker disk 34 are inclined inwardly and rearwardly, as designated by the numeral 42 in Fig. 3.

Immediately behind the breaker disk 34, the tubular housing 19 has a tapered end 43, in which a nozzle 44 is removably mounted, the bore of the nozzle 44 being reduced intermediate its ends, as designated by the numeral 45. The nozzle 44 is removable, and may be replaced by another nozzle having a passage differing in cross section from the passage shown, to vary the speed at which the mixture leaves the tapered end 43 of the housing 19.

The nozzle 44 is held in place by a foot plate 46 on a conduit 47 which communicates with the intake manifold 2.

A pipe 48 leads rearwardly from the radiator 7 (not shown) of the internal combustion engine,

and is connected to a valve casing 49, which may be mounted on the intake manifold 2 or elsewhere. The valve shaft of the casing 49 is designated by the numeral 50 and has an arm 51, shown in Fig. 2, and adapted to be connected to the spark lever (not shown) of the engine.

valve 15 of Fig. 2.

As to the general operation of the device, it will be-understood that the supplemental air enters the heater 5 through the strainer 6. As the air moves through the heater 5, the temperature of J the air is raised. because the heater 5 is close enough to the exhaust manifold 3 to accomplish this result. The air follows the return bend 9 (Fig. 2) of the heater and moves into the conduit 10. From the conduit 10, the heated air is dis.

Here the auxiliary air encounters the mixture of fuel and air which the carburetor 52 has produced. In the connection 11, an initial mixing of the heated auxilliary air and the products from the carburetor 52 takes place, and the air passing through the conduit 10 tends to draw the mixture from the carburetor.

From the connection 11, and under the control of the butterfly valve 15, the mixture proceeds to j the chamber 21 of the housing 19, shown in Fig. 3.

blades 32, is rotated rapidly, the breaker disk 34 is rotated rapidly and rapid rotation is imparted to the discharge member 39.

The blades 32 of the admission rotor, owing to The lower walls of the slots 41 in thetheir inclination circumferentially of the shaft 23, tend to advance the mixture. Because the lades 32 are thin, resilient and vibratory, they have an important effect in securing homogeneity of the mixture. A thorough mingling, moreover, is brought about, because the outer ends of the blades 32 are not in a circle represented by the inner wall of the chamber 21, but are slightly eccentric thereto, as shown at 33.

From the admission rotor, the mixture proceeds through the openings 35 of the breaker disk. Owing to the specific shape of these openings, and to the specific shape of the slits 37, shown at 38, the mixture is further and thoroughly broken up, and this breaking up is enhanced, by reason of the fact that, as shown in Fig. 4, the breaker disk 34 has a slight eccentricity with respect to the wall of the chamber 21, as does the admission rotor 32.

The mixture now passes to the discharge member 39, the blades 154 of which feedthe mixture into the tapered end 43 of the tubular housing 19, the speed of the mixture being increased, owing to the presence of the tapered end 43 of the housing. The speed with which the mixture proceeds is enhanced, further, because the nozzle 44 is provided with the reduced opening 45, and,

as has been stated hereinbefore, one nozzle may be taken out and another nozzle substituted therefor, in order to regulate the speed with which the mixture passes into the conduit 47. From the conduit 47, the mixture moves into the intake manifold 2, and the engine is provided with a fuel mixture which is finely divided, homogeneous, and thoroughly mingled, the temperature of this mixture being raised, owing to the presence of the heater 5, through which the auxiliary supply of air has passed.

If the operator desires that the intake manifold shall receive a supply of moisture, this can be accomplished through the instrumentality of the pipe 48 which is connected. to the radiator (not shown) of the engine. The pipe 48 discharges into the valve casing 49, and the pipe 100, shown in Fig. 1, conducts the moisture from the valve casing 49 to the conduit 4'7, and, therefore, to the intake manifold 2. It is not advisable to have moisture delivered to the intake manifold 2 while the engine is idling, and this result can be accomplished by means of the arm 51 on the valve shaft 50 of Fig. 2, it being recalled that the arm 51 is operatively connected to the spark lever (not shown).

. When the engine is first started, it is often desirable not to have an auxiliary supply of air. The auxiliary supply of air can be cut off, wholly or to any desired extent, by closing the choke valve 7 of Fig. 1, through the instrumentality of the mechanism shown at 8 in Fig. 2 of the drawings, and under the control of an operator.

It is to be observed that the carburetor 52 is connected to the butterfly valve 15 of Fig. 2 for movement in synchronism therewith by the mechanism shown at 91 and by the shaft 16 which carries the butterfly valve 15 of Fig. 2. The supply of heated air, therefore, is regulated in accordance with the richness of the mixture proceeding from the carburetor.

Generally stated, the device embodies a means for providing a heated supply of auxiliary air, at

the will of'an operator, and this heated supply of auxiliary air'is mingled with the mixture of air and fuel proceeding from the carburetor. The combined mixture moves on to the mechanism shown in Fig. 3,. wherein the various steps of feeding, breaking up and mingling the mixture take place, as hereinbefore described, the mixture passing on to the intake manifold 2, ordinarily moistened by the vapor from the radiator proceeding through the pipes 48 and 160 of Fig. 1, but without that moisture if, while the engine is idling, the valve mechanism in the valve casing 49 is operated by the mechanism shown at 51 in Fig. 2.
