Specication of Letters Patent. Patented Mar. '14, 1911.

Application filed July 3, 1910. Serial No. 573,38@`

novel manner andvconnecting means between A the weights andparts of the fly Wheel for,

varying the resistance offered to the outward movement of the weights under centrifugal actionwhen the fly wheel is in inet-ion. f

The invention' consists of thelnovel features, det a1ls of construction"l and combinan'tion of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claim.,

Referrin of the applicationfliigure l is a side view of a fly wheel provided with a series of weights embodying the invention. Fig 2 is asectional view on the line ax-m of Fig. 1.

Corresponding and like parts are referred to in the following description,and indicated in both views of the drawing, by the Same refeleIlCe ChaIaCl'felS. v

for each spoke and is arranged so as to cross The flywheel may be of any construction and as shown comprises a hub 1, spokes 2 and a rim 3. A weighted arm is provided a spoke intermediate of .its ends. lThe weighted arms 4 are pivoted at their outer ends to the rim of the wheelat 5 and their inner ends are connected to the' spokes next in order by means of connections embodymg springs. Each of the arms 4 comprises parallel members or bars, which are arranged to eXtendalong opposite sides of the spokes.- Weights 6 are mounted upon the inner ends of the arms 4 and in practice fly outward undercentrifugal action when the wheel is rotated. The connecting means between the inner ends of the arms 4 and the spokes comprise turnbuckles 7 and spring clevises 8. The spring clevises 8 may be of to the drawing,'forming a part` any formation and the turnbuckle 7 may be of usual construction and serve to vary f the effective tension of the springLclevises so.

as to offer a greater or less resistance to the outward movement of the Weights 6. Each f spring clevis consists of a frame, which is pivotally connected to an arm, a rod 9 having slidable connection with the frame and a spring mounted upon the outer end of the" rod 9 and confined between the same and the frame. yOne end of the turnbuckle7 has screw-thread connection with the rod 9 and the opposite end isv connected by means of a swivel joint with a link attached to the spoke. The arms 4 are limited inth'eir inward movement by means of stops l0, which consist of shoulders cast upon the spokes 2. It will thus be understood-that adjustment of, the turnbuckle 7 varies'thetension of the spring, forming connecting means between the arm and spoke, so that more or lessA speed is required to cause outward movement of the weights. .By vreason -of the inner or free ends o f t-he weighted arms being connected ,75 to the spokes in the manner shown the out- Ward movement of the weights under cen. i trifugal action'modifies the speed of' the fly f wheel and particularly is this the case when the load varies, thereby enabling the fly' -wheel to cause .the engine to run nearly uni-- formly. .y

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.-

Having thus described .the invention what is claimed as new, is In combination Ya flyl wheel .embodying spokes and a rim, arms crossing the spokes and pivoted at their outer ends to the rim` l each of said arms comprising spaced members embracing the spokes, weights mount- In testimon whereof I aiiix my signature d upon the free ends of the arms, nfieans in presence o two witnesses.

' or rlimiting the inward movement o the f arms, spring 'connections between the weghtp WILHELM H' HEINE 5 ed ends of the arms and the succeeding Witnesses: l t

spokes, and means for varying the tension. of P. H. BURNER,

the spring connections. p WM.` E. HEINE.
