Specification of Letters Patent.
Patented Feb. 2, 1909.
To all whom it may concern:
Be it known that I, RUssnLL'W. GUIL- roan, a citizen of the United States, residing at Auburn, in thecounty of Dekalb in the State of Indiana, have invented certain new and useful Improvements'g'n Fly-Wheels; and I do hereby declare that he following is a full, clear, and exact description of theinvention, which will enable others skilled 'in the art to which it appertains to ,makeand use the same, reference being had to the accompanying drawings, which form part of this specification. i
My invention relates to improvements in fly-wheels.
It is well known that in automobiles andother motor-vehicles automatically operated cooling fans for the engine cylinders are; employed, and are so arranged as to direct, a
cooling blast of air upon the engine; and,
that this coolingblast is usually directed uplon the central portion of the engine from w ichit is irregularly deflected with more i or less uncertain efficiency to the heated cylinders. I
The object of my present invention is to provide a fly-wheel of novel construction whose spokes and perimeter are soarranged as to perform the additional function of cooling fans, and to direct the cooling blast in two directions to the opposite cylinders of the engine by diverting the blast at acute angles to the axis of the wheel instead of in a direct line with the axis.
The principal novel feature of my invention resides inthe construction and relative arrangement of the wheel spokes to divert the cooling blast from a right line with the axis to lines inclined to such axis, for the purpose of directing such blast directl upon opposite and separated engine cy inders.
Similar reference numerals indicate like parts in the several views in which- Figure 1 is a perspective view of the flywheel showing theconstruction of the spokes and the beveled side of the perimeter. Fig. 2 is a horizontalQcentral section of the flywheel showing more clearly the beveled perimeter and the flanged spokes, the flywheel being in position on the crank-shaft, and also showing a plan view of the crank case and the engine cylinders, the latter being partly broken away. Fig. 3 is a plan] view of the fly-wheel with its perimeter partly broken away to show more clearly the relation, of the inclined spokes to the lateral flanges thereof.
My improved fly-wheel of any proper dimensions' and material has af'suitable perimeter 1, a suitable concentric hub 2, having a proper central 0 ening 6 and a series of radial spokes 3 pre 'e'rably integral with both the rim and the hub.
The spokes .preferabl have at their outer ends a width equal to t at of the rim 1, and at their inner ends a width equal tothat of. the hub.
The width of thewheelrim 1 is preferably somewhat greater than the length of the hub, as shown in Figs. 2 and 3.
The wheel rim has one-edge thereof in- .wardly beveled as shown at 4, for the purpose hereafter described; i The spokes are inclined to correspondng radial planes arranged at right angles with the axis of thehub as shown in Fig. 3, and each is provided upon one edge thereof with a lateral flange 5, arranged at-an angle theretoand in theplane of the axis of theso and theflange then gradually tapersto the adjacent face of the l The angle of inclination and the width of the spokes, as well as the contour and amount of lateral extensionof the flanges 5, and the inclination of the beveled portion 4 of the rim, are all immaterial so ion as they perform efliciently' their intended notion about to be described.
In Fi .2 the relative arrangement of the 'fiy-whee and the cylinders? to be cooled is shown. These cylinders preferably have the usual cooling fins 8, and are fixed upon opposite sides of the crank case 9.
The operation andmanner ofemploying my inventionqthus described is obvious and briefly stated is as follows: The fly-wheel is fixed upon one end of the crank-shaft 10 in roper proximity to the engine cvlinders to e cooled, with the face of the fly-wheel having the flanges 5 thereon adjacent to and in arailel relation with the surfaces to be ,coo ed. The wheel is then rotated or driven to the right in Fig. 1 filiereby the inclinatio air blast produced by the revolution of the wheel in two directions and at acute angles [0 the plane of the wheel or u on the sepirated and alined cylinders to e cooled, as indicated by arrows in Fig. 2, instead of directing the air in ou direction and at right-angles to the plane of the wheel as is done in the usual construction of cooling fans.
My improved fly-wheel is thus of simple and economical construction and not only is adapted for the additional air cooling function, but is adapted to perform that function by driving the air blast and directing it in two opposite directions, and at an acute angle to the face of the wheel.
Having thus described m the manner of em )loying tie same what I desire to secure by etters Patent is:
1. fly-wheel having a perimeter and ('OlllLlllXlL hub rigidly umted by radialspokes whose sides are laterally inclined to the invention. and
plane of the wheel, one edge of the said spokes being provided with a lateral flange or projection in right angular relation to the plane of the wheel, as and for the purpose described.
2. A combined fly-wheel and cooling fan, consisting of a wheel-rim and concentric hub rigidly connected by a series of radial spokes, whose sides are inclined to the plane of the wheel the said rim having one edge inwardly beveled, and the said spokes having lateral longitudinal flanges projecting beyond the said beveled edge of the rim and being laterally alined with the axis-of the wheel.
Signed by me at Auburn, Dekalb county, State of Indiana, this 22nd day of January, A. D. 1908.
