To all whom it concern; 1 Be it. known; that. 11', EDWIN. Y. OnosroN, residing at Hazard, in the countyfof Sherman and" State of Nebraska, have invented certain newtand useful-1m rovem'ents Fans :for Cooling Explosionngine's'ynf which the following is a specification;
This invention comprehends certain new and useful improvements in means for cooling and keeping free from dust the cylinder andother-working arts of internal combustion engines, ant the invention has for its object a simple, durable and efiicient construction of fan for this purpose, the invention consisting in certain constructions hereinafter fully describeand claim.

. cool the sameand'keep it free-from dust.
The-shaft l2f ear'ries at one end a relatively heavy fly wh'eel I5 and at its opposite end is ,prov'idedwith a pu'lley 16 connected by a. belt 16" to: the; fly-wheel. 1 of the engine or to any other desired Wheel (not shown) on the crank, shaft 2. i g
The drive pulleyv 16 of the fan, shaft is a combination ratchet and friction drive pulley, the particular construction and arrangement 'of the parts thereof being best illus-, 'trated in Fig. -3. In this view, it will be seen that one end of the. shaft 12 carries a set collar 17' which-is keyed thereon as well as, being secured thereto by a set screw. A friction disk 18 of any desired material encircles .the' shaft and .is adapted to bear against said collar, and a secondfi'iction mvention,
disk 19 is mounted on the shaft; spaced from the disk 18, 20 'desi ates two friction sgools'that are mounte .on the shaft within 1;
e hub of'the pulley 16 and which are preferabIy arranged for interlocking engage-v ment with each other as shown, one of these pulleys being adapted to bear frictionally against the friction disk 18 and thewgither I being formed withlrecessesat its oute'lr end desifiled for engagement by .one or more paw 21 that are preferably gravity actuated and that are carrled'in one end ofthe pulley which, is ada ted to bear against the friot'on disk d which is splined onthe shaf 12 for 16. 23 designates a friction washer 19v an a longitudinal shdingrmovement th reon, and a spring 24 bears against said washer to holdit against the disk 19., the other ehid ofsaid sprin bearing against a set collar 25 keyed on t e shaft or adjustably held-there r on by means of a set screw as shown.
From the foregoing description in con- ,nection with the accompanying drawing,
it will be evident that when the. engine starts, all jerking of the fan shaft 12 is avoided, owing tothefact that the spools 20 will first slide frictionally around in contact with thefrictional disks 18 and 19;'until the spring 24 shall have exerted its tension to pickup the motion and to overcome the torque of-thefly-wheel 15 and fan blades carried by said shaft. ,Hence the motion of the main. engine shaft will be imparted I gradually to the fan shaft without any shock,
and consequent injury to the parts, and it is .manifest that a relsg ziyely heavy fly-wheel 1 may be .therefor employed on the fan shaft-12, so that the momentum thereof will What is claimed as new is:
impart a continued movement to the fan shaft, the connection betweenthedrivepulley blades, even after the main engine has been i and the fan shaft embodying afriction s 001 brought to a standstill. mounted on the shaft, a spring pressed ric- Having thus described the invention, tion disk adapted to bear against'one end of said spool, and awls carried by the drive pulley, said spoo being formed with ratchet notches designed to receive said pawls.
In testimony whereof I afiix my signature presen'ce of two witnesses.
