PETER V. HANSEN, OF SALEM, SOUTH DAKOTA.

ENGINE-COOLING FAN.

Application filed April 1,

This invention relates to new and useful improvements in engine cooling fans and has for its primary object to provide a fan wherein the blades thereof-are so associated with the fan body as to facilitate the manual turning of the fan blades from blowing to suetion position to enable the warm air to be drawn from the motor and forced to the diator in contradistinction to the revcrse'action so that the engine may be maintained in warm condition in very cold climates, such a reversal of position of the blades also being effective in directing the warm air from the motor through the radiator to thaw the same in the event it becomes frozen.

A further and important object is to pro vide a fan construction of this character wherein the angularity of the blades with respect to the fan body may be easily changed and this without unusual effort.

A further and important object is to provide an engine cooling fan wherein the ends of the blades are curved slightly rearwardly for directing the air blast against the sides and top of the motor rather than throughout the entire area within the engine hood which will of course result in the more proper cooling of the engine.

lVith the foregoing and other objects in view as the nature of the invention will be better understood the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate corresponding parts through out the several views:

Figure l is a fragmentary front elevation of my improved fan oartly disclosed in'cross section.

Figure 2' is a fragmentary view partly in side elevation and partly in cross section, and

Figure 3 is an enlarged longitudinal section taken substantially upon the line 33 of Figure 1 for more clearly disclosing the adjustable mount between the various fan blades and the fan body.

Now having particular reference to the drawing, my novel engine cooling fan consists of a body 5 preferably in the form of a circular plate and constructed at its center with an opening to permit of the attachment 1927. Serial 1m 180,219.

of the same to the usual pulley carrying idle shaft of an automobile engine. Arranged at the edge of this circular body 5 and projecting radially therebeyond are rigid sleeves 6 preferably four in number. Rigidly mounted beneath these sleeves 6 andin spaced relation therewith are outwardly extending circular lugs 7, each of which has an opening 8 1.11 registration with the bore of its respective sleeve 6, see Figure 3.

The fan blades are designated. by the referwhile arranged upon each of said pins 11in back of its pin 12 is a plate 13. As clearly disclosed in Figures 2 and 3 the inner ends of the various sleeves 6 are formed at two diametrically oppo-sed points with transversely registering notches let for receiving the ends of the respective pins 12. For maintaining these pins 12 within predetermined registering notches 1414t of the lugs 7 each pin 11 is surrounded between; the plate 13 and its adjacent lug '7 with an expansiblc coil spring 15. Obviously by reason of the particular manner of connection between the fan blade pins and their supporting sleeves said blades may be secured to the fan body 5 at such angles with respect thereto as to cause the air to be blown over the motor or drawn from the motor and forced through the engine radiator. Furthermore by reason of the particular connection .it will only be necessary that the various blades be forced inwardly so as to disengage the pins 12 from the notches in the sleeves 6 after which the blades may be turned for causing the engagement of the pins in the other registering notches where they will be held by the pressure of the expansible spring 15.

It will thus be seen that I have provided a highly novel, simple, and relatively inexpensive motor cooling fan wherein the blades thereof may be rapidly changed so as to cause the air to be blown over the motor or to be drawn therefrom and through the engine radiator and wherein by reason of the particular construction of the blade the air directed against the motor will be caused to closely v impinge against the sides and top thereof for maintaining the same at proper temperature. v p

Having thus described the invention, What 5 'I claim as new is z- In an engine cooling fan of the character described, a disk-shaped fan body, outward 1y projecting lng'members radially formed on said body inwardly from the periphery V 10 thereof, sleeves formed radially at the periphery of the-body and having their inner end blade in a. set position.

In testimony'whereof I ailix my signature.

PETER V. HANSEN.
