ROLAND A. LABBE, OF ONAGA, KANSAS.

Application filed March 2'4, 1925. Serial No. 17,963.

This invention relates to a device for supplying moistened air collected from the radiator through the overflow pipe associated therewith to an internal combustion engine whereby the efliciency in the operation of the latter is increased and furthermore reducing the collection of carbon in the cylinders to a minimum.

One of the important objects of the present invention is to provide a device of the above mentioned character which includes a means for receiving the steam generated in the radiator, additional means being provided for delivering the steam to the hot air pipe associated with the carburetor of an internal combustion engine whereby the vapor is heated before becoming commingled with the mixture entering the intake manifold;

A further object is to provide a device of the above mentioned character, which may be readily and easily installed without necessitating any material alterations of the parts of the engine with which the same is associated, the same being further, simple in construction, inexpensive, strong and durable and further, well adapted for the purposes for which it is designed.

Other objects and advantages will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals designate like parts throughout the same:

Figure 1 is an elevational view of the device embodying my invention showing the same installed, and

Figure 2 is a perspective view of the steam collecting casing.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a substantially rectangular shaped steam collecting casing, the same having the lower portion of the side walls thereof gradually converging toward the bottom of the casing in the manner clearly illustrated in Figure 2. The steam collecting casing 1 is preferably adapted to be secured to the core of the radiator 2 of an automobile on the inner side thereof in any suitable manner. The casing is preferably supported at a point adjacent the upper water chamber of the radiator in the manner as clearly illustrated in Figure 1. Extending upwardly through the top of the casing l is the tube 3, the lower end thereof extending downwardly into the upper portion of the casing. The upper end of the tube which is disposed outwardly of the casing connects with the usual overflow pipe 4 of the radiator 2 so that the vapors generated in the upper water chamber of the radiator will pass through the pipe at and the tube 3 into the casing 1.

The steam collecting casing 1 is provided with the threaded opening 5, the same being located at a point adjacent the top of the casing. A steam outlet pipe 6 is threaded at its upper end in said opening 5, and the opposite end of the pipe 6 communicates with the hot air pipe 7 which is associated with the internal combustion engine designated generally by the numeral 8 and the air intake of the carburetor 9 in the manner well known in the art. The purpose of this construction will hereinafter be more fully described.

The reduced lower end of the casing 1 terminates in the threaded pipe 10 and a water discharge pipe 11 is connected thereto, said water discharge pipe extending downwardly adjacent the inner side of the core of the radiator in the manner as clearly illustrated in Figure. 1.

With the parts arranged as shown in Figure 1 of the drawing, itis obvious that the steam generated in the upper portion of the radiator will enter the overflow pipe at and will be collected within the casing. When the internal combustion engine 8 is in operation, the suction will cause a supply of steam to enter the delivery pipe 6 and be discharged into the carburetor through the hot air pipe where it is heated so that a quantity of preheated moistened air will be supplied to the mixture entering the intake manifold, thus increasing the efiiciency of the operation of the internal combustion engine as well as reducing the consumption of fuel necessary to operate the latter. Any

excess steam or water which collects in the casing 1 will be discharged out through the pipe 11 so that there will be no possibility of any water entering the carburetor through the steam supply pipe 6,

A device of the above mentioned character Will at all times be positive and efficient in carrying out the purposes for which it is designated and may be readily installed on an automobile without necessitating the material alterations of the parts with Which the device is associated.

The device may not only be used in connection with an automobile, but may also be used in conjunction with engines of the stationary type so that steam generated by the engine may be collected and preheated and admitted to the carburetor in the same manner as heretofore described;

While I have shown the preferred einbodiinent of my invention it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to, withoutdeparting from the spirit of the invention and the scope of the appended claim.

Having thus described the invention what I claim as new is A steam collecting device for supplying moistened air from a radiator to an internal combustion engine including a casing having a lower end restricted and merging intoa tubular depending extension, a tube extending through the top of the casing and terminating within the casing at a point between the top of the casing and the center thereof, said tube adapted to have its outer end connected withthe radiator, one side of said casing being provided with an opening positioned between the top of the casing and the inner terminal of the tube, said opening adapted to receive a pipe leading from the intake manifold of the en: gine.

In testimony whereof I afiix iny signa ture.
