`'The invention relates to improvements in combination humidiliers and decarbonizers and an obiect. of the invention is to provide a device which can be readily attached to the customary radiator of an automobile and View. the invention consists essentially in the.

connected with the intake manifold thereof and which will supply hot vapor to mix with the firing mixture passing to the cylinder, thereby improving the firing mixture and also preventing the accumulation of carbon within the cylinder. Y

A further object: of the invention is to embody t-he device as part of the radiator cap so that it can be readily removedl and such that it is at all times visible to the driver.

A further object is to construct the device in a simple, durable and inexpensive man-ner and such that it will not interfere in any way with the present car construction.

.A further object is to construct the device so that there is no possibility of water flooding into the manifold from the radiator through the device and a further object is to provide a device with a valve controlling the vapor passing to the manifold and actuated.

from the dash. Y

Vith the above more important objects in arrangement and construction of parts hereinafter more yparticularly described, reference being had to the accompanying drawing iu which: l

Fig. 1 is a side view of the front part of an automobile equipped with my invention, the hood being broken away and the dash and foot boards being, shown in vertical section.

Fig. 2 is an enlarged detailed vertical sectional view centrally through the device.

Fig. 3 is an enlarged detailed sectional view centrally through t-he hose connecting the endsof the pipe. l v

Fig. 4 is a perspective view of certain parts showing the manner in which they are formed and how they are assembled. v

In the drawing like characters of reference indicate corresponding parts in the several figures.

The automobile presents the customary radiator 1, intake manifold 2, engine Vhood '3, dash l and foot boards 5, these being of ordinary construction and on such account not further detailed.

The radiator presents the usual filling r opening 6 which is enclosed by the customary exteriorly screw threaded upstanding annular flange 7. The usual radiator cap threads onto thisange. my case, however, the cap is formed as part of my device.

The cap 8 which is in reality the base of my device is adapted to screw thread Lonto the flange and lit is vprovided with two outstanding diametrically opposed hand grips 9 and 10 which facilitate in the screwing up or unscrewing of the cap. The body of the.

cap is provided on the top side with an up- Y standing marginal flange 11 within which I seat a cylinder 12. which 'is preferably transparent. have found a glass cylinder serves my purpose. vA gasket 13 is placed beneath the cylinder. A flanged topor cover is placed overthe upper endy of the cylinder l v17 andaccordingly holds the coverand cylinder tightly. in place.

The cap 18 is cylindrical `and it is provided with an extending hexagonal head 19. On the cylindrical body of the cap 18, I mount slidably a disc20 having a slight boss 21; which prevents the tilting ofthe disc. :The disc under certain lconditions is adapted to moveV up and close the lower ends of holes or ducts 22 and 23 passingthrough the body of the cap 8 and opening to the interior of the cylinderv 12. The tube orpipe 16 is provided .within the cylinder 12 `and ladjacent the cover 14 with a vhole orduct 24e and the upper end of the tube is provided with ak seat 25 adapted to receive a ball `valve 26. A short sleeve 27 is screw threaded to the up? per 'end of the tube and forms a' valve casing. A pipe 28 whichis really an extension of the pipe 16 beyond the valve is screw threaded to the sleeve andis connected by a length of hose`29 to a further pipe/30, the latter pipe opening to the interior of the intake manifold 2. The pipe 30 passes through the hood in a location adjacent the rear side of t-he radiator and preferably at the customary I top hinge of the hood'as I find at this location there is usually a place where one can pass a small pipe through without actually having to drill a hole and further by passing it through at this point, the hinge is not interfered with. It will be observed that the length of hose V29 is above the hood. This arrangement permits me to readily disconnect the pipes 29 and 30 by slipping the hose endwise on the pipe 29 after which one can remove the device from the radiator by unscrewingthe cap 8; In order to prevent the ball valve from seating against the lower end of the pipe 28, I have passed a pin 31 across this pipe. kA controlling valve 32 of any approved type is inserted in the pipe 30 and presents a lever 33 to which I attach a push rod 34 passing slidably through the dash and fitted with a finger grip 35. y

When the device is in Vuse and the engine is initially started, onefkeeps the `valve 32 closed' After the engine has'warmed up and the water in the `radiator has become heated andris giving off water vapor or steam, the Valve 32 can be opened by manipulating the pushrod 34 :from the dash. When'this occurs the suctionfrom the engine cylinders will raise the valve 26 from its seat and will draw the hot vapor from the radiator through the. ports 22, 23 and 24 and pipes and discharge it into the intake manifold where it mixes with the ingoing firing mixture. This hot vapor gives a much more eflicient tiring mixture and also prevents the formation of carbon within the cylinder and particularly on thev spark plugs.

f One can control the amount of vapor admitted to the intake manifold by opening the valve 32 a greaterl or less amount as conditions warrant. i

Under certain road and engine conditions, there is a possibility of thev water in the radiator boiling and in order to pre-vent this entering the int-akemanifold, I have provided the disc 20 which is adapted'when struclby the' boiling water to fly up and seat against the under side of the body of the cap 8 and in so'doing close the openings 22 and 23. y l

Obviously the device can be readily re- Y moved'irom the radiator when it is desired to place more water in the radiator and the driver is at all times able to see just how the device is functioning as he can see the steam rising in the cylinder 12. e

Whilst I have described the cap 8 as interiorly screw threaded to fit an exterior screw threaded flange 7, it will be readily understood that the cap 8 could be modiied to fit the various existing types of flanges presented by the varying radiators.

VVh'at I claim as my invention is:
