INVENTOB: A. HOILAJYD, BY ms flTI'OBJVEI Z UNITED STATES PATENT OFFICE.
ALBERT HOLLAND, OF FARGO, NORTH DAKOTA.
AUTOMATIC REVERSIBLE FAN FOR EXPLOSIVE-ENGINES.
To all whom it may concern:
Be it known that I, ALBERT HOILAND, a citizen of the United States, residing at Fargo in the county of Cass and 'State of North Dakota, have invented a new and useful Automatic Reversible Fan for Explosive-Engines, of which the following is a specification.
My invention relates to improvements in means for regulating the temperature of radiators for explosive engines, and it consists mainly of an automatically reversible fan for circulating either warm or cold air or no air at all through the radiator of the engine as may be required by the existing temperature therein.
In the accompanyin drawing, Figure 1 is a partial sectional si e elevation of a portion of an explosive engine and its radiator and cooling fan of the type and arran ment common in automobiles and embodying my invention. Fig. 2 is an enlarged longitudinal vertical section through the thermostat employed in my device. Fig. 3 is a section on the line 33 in Fig. 1 with many parts omitted. Fig. 4 is a front eleva tion 0 a portion of the radiator shown at the right hand end of Fig. 3.
Referring to thedrawing by reference numerals, 5 desi ates the water jacket of an explosive engine having a base 6 with a ra iator 7 so connected thereto that the water heated by the explosions in the engine ma flow through a pipe or hose 8 into the ra iator, then down through the radiator and return to the engine or its Water jacket through the base 6. The radiator is made with any form of pipes 8" for the water to pass downward through it'so as to become cooled by an air current drawn through the interstices 9 of the radiator.
Such circulation of air is usually induced by a fan 10 which has a pulley 11 driven by a belt 12 and a pulley 13 whlch is fixed on a shaft 14 and operated from the engine by any suitable means (not shown).
In the present drawing the fan pulley 11 is fixed on a sleeve 15, which rotates on a shaft 16, and the latter is fixed in a frame arm 17 and provided with a head 18 between which and the frame arm the sleeve is retained. The front end Of'the sleeveis provided with a spider 19, in the arms of Specification of Letters Patent.

Application flied January 21, 1918. Serial No. 212,917.
which are journaled short radial shafts 20, each of which carries at its outer end a fan blade or wing 21, and at the inner end is provided with a crank 22, which is engaged -'n a peripheric groove 23 of a head24. Said head is slidably mounted on the sleeve 15 and may have a feather key 25 to cause it to rotate with the sleeve.
In said head is a second peripheral groove 26 in which engages a shifter fork 27. Said fork is rigid wlth a rod 28, which is guided in a bracket 29 and has its inner end passed through a stufling box 30 in a thermostat Water chamber 31, in which it connects with the adjacent hollow disk 32; a series of such disks are attached together a d partly filled with alcohol or similar fluid, which when heated develops gas and thereby swells out the disks and causes the rod 28 to be pushed outward. 33 is a spring acting on a collar 34 to. push the rod inward again when the gas in the disks is condensed by a fall in the temperature.
The water chamber 31 is secured by screws 35 to the water jacket 5 and receives water from the latter through a port 36 and delivers it through a nipple 37 to a nipple 38 in the top of the radiator. Said two nipples may be connected by piping but to make things more convenient a hose 8 is used instead of a pipe.
In the operation of the device when the engine is running the fan will normally run with the wings 21 edgewise through the air and thus cause no draft, but if the water in the jacket and radiator gets undesirably warm, the hot water moving through the chamber 31 will cause the disks 32 to expand and push on the shifter rod 28 until the wings of the fan are suliiciently turned to draw cold air through the radiator and thereby cool the water to the desired temperature. And as the temperature falls the disks will contract and allow the spring 33 to turn the wings or blades 21 more and more edgewise again; and if cold wind or frost set in and further cool the radiator the disks 32 will further contract and allow the spring 33 to turn the wings to a reverse inclined position, so as to drive warm air from the fan chamber and the engine into the radiator and there by help heat the water circulated therethrough, or at least to keep out the cold air from entering the radiator and absorbing its heat.
What I claim is:
1. In an explosive engine, a radiator, a cooling fan operatively connected with the engine; said fan having radial wings tiltable about their radial axes, a collar slidable on the shaft of the fan and engaging the wings to tilt them, a thermostat inserted in the Water circulation of the engine and radiator and having a thermostatically pushed and ulled rod, a radial arm rigidly fixed on said rod and engaging the collar to slide it on the fan shaft.
2. The structure specified in claim 1, and a spring acting directly on the said rod of the thermostat to assist in the retracting of the rod when the temperature falls.
In testimony whereof I affix my signature.
ALBERT HOILAND.
