AUTOMOBILE RADIATOR VENTILATORa Application filed January 11, 1928. Serial No. 246,069.

This invention relates to ventilators use 111 in connection with the radiators of automobiles, more particularly to a type capable of attachment at the filler openings of the radiators.

The main object of my invention is to provide for eilective circulation of air through the upper headers of automobile radiators above the surface of the liquid. cooling medium therein to the end of counteracting vapor pressure and preventingexcessive evaporation through boiling, especially when highly volatile liquids, such as alcohol or the different compounded solutions now available on the market, are employed as cooling agents for cold weather driving. 2 v

My invention is further concerned with provisions to automatically control circulation of cooling air through the radiator in accordance wlth temperature conditions therein; as well as with provisions whereby the ventilators may be rendered inoperative when desired.

How the foregoing as well as still other objects and attendant advantages may be readily realized in practice will be manifest from the detailed description which follows of the typical embodiment of this invention delineated in the drawings.

' \Vith reference first more .in detail to F 1 to IV oi" these illustrations, it will be observedthat the ventilator of my invention embodies a flat hollow circular head 10 wherefrom depends a tubular shank or stem 11, which, in the present instance, is integrally formed with said head. As shown in Fig. Lthe stem 11 extends down into the upper header 13 of the automobile radiator through a central aperture in the screw cap 14: overthe neck 15 about the fillin g opening. The screw cap 14 is secured to the ventilator by a clamp nut l6which opposes a circumferential stop flange 1701i the stem 11 and engages the screw threaded portion 11 of the latter. interiorly by a central vertical partition 18 through the medial plane of the head 10 with provision, in said head, of horizontal axially-aligned circular anterior and posterior air influx and efllux openings 19, 20, and through the stem llfrespectively communicating vertical inflow and outflow duets 21, 22 which terminate at the lowerend of the stem 11 within the radiator header 13,- To

in laterally directed openings 21 22 facilitate angular flow of the air between the influx and efllux openings 19, and the communicating vertical ducts 21, 22, I employ, crosswise of said openings, deflector vanes 25, 26, which, as shown in Fig. I, are arcuate in cross section with their inner edges extending into closer proximity to the quence of this arrangcment,.the air flow is proportionately and uniformly distributed incidental to passageinto and out of the vertical flow ducts 21, 22. The vanes 25, 26, are supported at opposite ends by periinetric members 27, 28, in the present instance in the form of flange rings having a friction fit within count-o1. recessions 29, of the head 10. 1 l

3111 order thatthe device may. be rendered inoperative at will, I may equip either or both the removable vane-supporting inserts with a shut oil valve'such asshown in Figs. l, 11 and V, having tl e form of a split band 31 with hearing at the inside of the ring flange 27. At the bottom, the valve s a cut out 32 for normal registry lei? the The ventilator is subdivided duct 21. A lateral projection or tongue 33 of the valve band 31 extends through an arcuate motion limiting slot 8% in the flange ring 27 and serves as a manipulating handle, see Figs. II and III more particularly. The port 32 may be protected by wire mesh screening as conventionally indicated in Figs. I, III and V to preclude entry of dust into the radiator with the air.

For the purpose of automatically controlling the flow of air through the radiator in accordance with temperature conditions within it, I provide, as shown in Fig. I, a sleeve valve around the lower end of the stem 11. This sleeve valve has ports 36, 37 for registry with the lateral openings 21, 22" of the vertical air flow ducts 21, 22, and is secured to the upper end of a conventional bellows thermostat 38. At the bottom, the thermostat 38 is attached to a plate 39 which immovably supported by screws d0 taking into a fixed collar a1. on the stem 11.

The operation of the device is as follows: Incidental to travel of the automobile, air forced into the anterior influx opening 19 of the head 10, and directed, by concerted action of the deflecting vanes 25, downward into the vertical inflow duct 21 for discharge through the lateral outlet 21 and induction into the frontal portion of the radiator header 13 as indicated by the arrows inFig. I. An air pressure is thus set up within the radiator head with resultant dis placement concurrently of a corresponding amount of air therefrom, escape being by way of the lateral opening 29f into the vertical outflow duct 22, and thence into the posterior efilux opening 20 of the head 10 where the deflecting vanes 26 redirect the air for horizontal rearward discharge from the ventilator. In this way, it will be seen that air is constantly circulated through the upper header of the radiator over the surface of the liquid medium therein to assist in maintaining it cool, thereby counteracting and carrying oil vapor pressure and at the same time preventing excessive evaporation. Operation as just described is of course subject to control by the sleeve valve under governance by the thermostatic bellows 38, in accordance with the temperature within the radiator. In other words, in pract .e, as the temperature within the radiator rises and the bellows 38 expands, the sleeve valve 35 is gradually moved upward from the full closed position when the motor is cold (as at starting), to full open or illustrated position in contact with the collar 41, with attendant variation in the air flow.

Figs. VIII and IX show an alternative form of automatic flow control in which the thermostatic bellows 38* is attached to the lower end of the stem 11, and enclosed by the sleeve valve 35* which it carries.

Thus as the bellows 38 expands, the sleeve valve 35* is moved downward (instead of upward as in Fig. I) to bring its ports 36*, 37* into registry with the lateral openings 21 22 of the vertical iiow ducts 21, 22.

In instances when the thermostatic control is not desired, I may employ, instead of the filtering screen on the shut-01f valve 31, a collar such as shown at 42 in Figs. VI and VII to fit the lower end of the stem 11 and having perforations 1-8 distributed over areas corresponding to the openings 21, 22 into the vertical ducts 21, 22. The screen collar 12 is detachably held in place through cooperation of bayonet-lock notches it in its upper edge with studs projecting laterally from the stem 11.

From the foregoing it will be seen that I have provided a very simple and ellicient means for setting up circulation of air within the upper header of the radiator with attainment of the various advantages hereinbefore pointed out. I do not wish to be limited to the precise details of construction herein shown since my invention is capable of cmisiderable modification; for example, the ventilator may be constructed il'itegral with the radiator cap 14, and the head 10 made otherwise than circular. Also, the stem 11 may, either in whole or in part, be made separate from the head 10 if found convenient from the standpoint of economical manufacture.
