FLY WHEEL.

APPLICATION FILED SEPT- 21, 1912.

VI/"ITJWLSTES:

1 1 tion of one of thefly wheels embodying the invention; and Fig. 3 is a medial transverse [To all whom it may concern I 'Be it known that-I JonN a citizen of the; United States, residing at perspective viewjofan embodiment of the .inventionina single cylinder internal coin- Toledo, Lucas county, Ohio, have-invented a new and. useful Fly-"Wheel, ofwhich the following is a specification. 5

Referring tothe drawings? Figure 1 is a bustion engine; Fig. 2 isian inner side elevasection of the fly wheel of Fig.

the V combustion chamber or "cylinder, the connecting rod 2 engaging'the crank 3 of,

the .ishaft ii carrying .in this instance the pair of fly Wheels 5. These fly wheels 5 are shown-as provided with radiating vanes 6,

7, adjacent their peripheries forming there- J T between air circulation pqekets'8. Certain of the vanes 7, herein shown as threeiin number, are of greater mass than the other vanesfi. These vanes 7 are ofsufiicient weight to serve as counterbalances 'for the reciprocating parts, to effect which they are disposed diametrically opposite to the crank 3 of the shaft 4 upon which the flywheels 5 are jmounted. The device to be driven by the engine may be directly connected to the shaft 4, or by pulley'thereon, as desired.

In operation, thepockets 8 entrain air,

which in the rotation of the wheels 5 tends by its'gravity to be thrown radially. The concave or dishing form of these pockets 8 allows the air entering on the inner open side to work outwardly, but the curvein the pocket walls adjacent the inner side of the fly wheel rims, deflects thi's'air for lateral discharge. lVith the vaned sideof the continuous change of atmosphere about the fly wheel toward the heat radiating ribs of the combustion chamber inclosing cylinder, these air currents from the fly wheel eifect JOHN D. srtnnnemn, or TOLEDO, OHIO.

jacent said ribs being warmed to any great extent. With the vaned fly wheels opposed to each other, as shown in Fig. 1, any cylindeer or cylinders in the range therebetween insuring effective cooling throughout.

The device is'simple, involving no extra worliing parts whatever, and due to its sim- I plicity, the'slight air resistance of the fly embodying the device of this disclosure.

What is claimed audit is, desired to secure by Letters Patent is:-

" 1. A fl'ywheel provided with vanes adjadished pockets to circulate air during'rotation of the flywheel.

2. A flywheel, a cranked shaft on which the wheel is mounted,'said flywheel having, on the side thereof toward the crank of the shaft, vanes partially formingintermediate their extent within the planes of the periphery of the wheel concave pockets to circulate. air during rotation of the fly wheel.

4 A flywheel provided with a rim/Mair circulating vanes radially inwardly extending from said rim, said vanes partially forming intermediate their radial extent within the planes of the periphery'lof the wheel dished pockets for laterally deflecting radiallymoving air during rotation of the flywheel.
