Letters Patent No.`111,677 dated February 7, 1871.

The Schedule referred to in these Letters Patent and making pari: of the same.

with the front head and a part of one disk removed so as to show the interior.

Figure 2 is a cross-section. -Figure 3 is a longitudinal vertical section. l

General- Description H. is a hollow cylinder, to be closed at each end-and packed so a's to hold oil or some suitable duid for the fans A A to revolve in. W is a shaft, driven by a belt on the pulley W. This shaft carries the fans A A A A..

, figs. l and 3, is a gear-wheel, attached to and revolving with the disk D.

E, figs. land 3, is a segment-gear, hung upon the spindle El and meshing with'the gear-wheel D. E2 is a counter-balance, hung upon the spindle El. In practice some device is attached to the spindle El for the purpose of transmitting motion to the throttle-valve of the engine, or, in case this governor is used for a water-wheel, to the gate or out-olf; A

The disk D is attached rigidly to the gear, and, conseijuently, any motion of this disk will cause a movement of the counter-Weight E?.

The buttress fans B B are attached 'to the disk D. l .A A are revolvingr fans, attached to the disk A and by it to the shaft W.

The fans A A B B may be inclined to the disks A D at any angle, but I prefer to set .them at right angles to the plane of the disks.

Ii prefered the fans may be made with curved or warped surfaces.

The operation of my invention is as follows:

The cylinder H bei-ng filled with oil or some other suitable duid, the fan-disks A A revolve in it with a velocity dependent upon that of the, engine. j This revolution ofthe fan-wheel causes a flow of oil against 'the bu'ttresses B B B B of the disk D, which action causes the disk D lto revolve, which transmits its uiospindle El and counter-balance lz'.

From inspection of the above, it will be seen thatl the force which the iowing Huid exerts against the bnttresses B B B B will be dependent upon the' velocity of the fan-wheel A A A A, and that the buttresscylinder D will move a force also in. proportion to this velocity, and will be checked in* its motion by the tion through the gear D and segment-gear E to Athe counter-balance E2 acting through the shaft El and segmentgear E.

Therefore, if by anysuitable mechanical device the shaft El be connected' to a cut-offer throttle-valve, it

will serve to regulate the speed'of the engine, Sto.

I ain awarev of a patent'being allowed to Andrew v J. Peavey for a governor for a stearn-engiue, and

hereby disclaim anything that may c'onict with his invention. A

Claim. What I claim as my invention is'- The combination of the fan-disk A' A A with the bnttressan disk .D B B, when constructed and arranged substantially as described, and for the purpose set forth.
