THERMOSTATIC FAN.
Specification of Letters Patent. 'Patented May 2, lllll..
Application led .Tune 3,1916. Serial No. 101,512.
To all lwhom it may concern.' s Be it known that I, ROY N. Con'rs, a citizen of the United States, and a resident of Marshalltown, in the county Aoit' Marshall and State of Iowa, have invented a new and Improved Thermostatic lFan, of which the mounted to turn and thermostatic ly contit) ,surrounding atmosphere.
following is a full, clear, and exact description.
'Ihe object ofthe invention is to provide a new and improved thermostatic tan 'more especially designed for use on automobiles and similar vehicles for controlling the air circulated through the radiatorv to maintain the water in the radiator at a desired temperature.
In order to accomplish the desired result, use is made of a fan wheel havin vanes trolled means mounted on the fan and connected -with the said vanes for turning the`- latter into a more or less open or closed posi 'f the tion according to the temperature o A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in
l which similar characters ot reference indicate corresponding parts in all the views.
[Figure 1 is a face view of the thermof static fan with parts shown in section' Fig. 2 is a longitudinal central section of the same; and
Fig. 3 is a sectional plan view of the same.
The head of the fan wheel 11 is mounted to turn on a shaft or 'stud 12 and on the said hub-10 is secured a pulley 13 connected by belt with other machinery for imparting a rotary motion to the fan wheel 11. It is understood that I do not limit myself to the means shown and described for rotating the fan wheel 11 as other suitable' means may be employed. 0n the hub '10 of the tan wheel 11` are secured radially disposed shafts 15 connected at their outer ends with ain-rim 16, and on the said shafts 15 are mounted to turn loosely vanes 17 of the usual shape. 0n the inner ends ofthe vanes 17 are secured bevel pinions or segments 20 in mesh loosely on the hub 10. 'Ihe bevel gear wheel 21 is provided with wings .22 disposed ra- A" cured to one end of the driving pulley 13.
Each of the thermostatic bars 23 is preterably made of two superimposed pieces of"y metal havingdi'erent coecients of expansion, the bar being approximately U-shaped,
as plainly indicated `in Fig. 1, so that thefree end of eachbar on expanding tends to rotate the bevel gear wheel 21. l v I en the air passing through or around:
ing the fan wheel 11 rises then the thermostatic bars 23 act onthe pins 25 and thereby turn the bevel gear wheel 21 whereby the 'pinions 2O are rotated and with the same the vanes 17 moving the latter into angular position, thus causing the air to be moved by therevolving fan wheel. 'Ihe amount of air .caused to circulate by the rotating fan wheel 11 .is sucient to maintain the water air decreases then the vanes 17 are correcrease the pumping action thereof.
From the foregoing it will'be seen that in the radiator at a desired temperature. When the temperature of the surrounding v by the use ot the thermostatically controlled turning means for the 'vanes the latter are automatically turned into a. position to pump morevor less air according to the tem, perature of the surrounding atmosphere.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:-
l. A fan comprising a hub, vanes mounted to turn on the said hub, pimons on the said vanes adjacent the hub, a gear wheel mounted to'turn loosely on the' hub and in mesh with the saidpinions, a driving means for the said-hub,l and thermostatic bars connecting the said driving means with the said gear wheel.
2. A fan, comprising ahub, a driving member on the hub, vanes mounted to turn ll.' on the hubo, pinions on the vanes adjacent the hub, a gear wheel loosely mounted on the hub and meshing with the pinions of the with a bevel gear wheel 21 mounted to rotate vanes, and thermostatic bars, connecting the gear wheel and driving member, each therlInostatic bar-having one end ixedly secured 'to one of the said parts and'its other endloosel secured to the other part. f, 3. tan, comprising a hub, a'driving member on `the Ihub and having pairs ot roo pins projecting from one end, vane/s moun i to tnrn on the hub, pinions on the vanes adjacent the hub, a gear wheel loosely mounted on the hub and meshing with the pinions, Said gear wheel having radial arms, and thermostatic bars, each having one end secured to an arm of the gear wheel and its other end extendin between a pair of pins of the driving mem er.
4. A fan, comprisin a hub, a rim, radial Vshafts between the l ub and rim, vanes mounted to turn on the shafts, p1n1ons ony the inner ends of the vanes, a gear loosely mounted on the hub and meshing with the pinions, Said gear wheel having radial arms, a pulley mouted on the hub and having pairs of pins projecting from one end, and thermostatic bars, each having one end secured to an arm of the gear wheel and its other end extending between a pair of pins of the pulley.
