FLY-BALL GOVERNOR.

Specification ofLetters Patent. Patented Nov. 30, 1909. Application filed February 1, 1909. Serial 1%. 475,386.

To all whom it mag concern:

Be it known that I, MAX HAEBERLEIN, a citizen of the Empire of Germany, residing in New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Fly-Ball Governors, of which the following is a specification.

This invention relates to-a fly-ball governor which combines extreme sensitiveness with a simple and durable. construction; and the invention consists of an inclosed fly-ball governor in which the fly-ball levers are mounted on knife-edges and are acted upon directly by adjustable counterbalancingsprings in such a way that there is no friction between the springs and the levers, the

levers being linked, independently of the springs, to a vertically slidable sleeve which is connected to the regulating mechanlsm.

In the accompanying drawings, Figure 1 represents a vertical central section of my improved fly-ball governor, Fig. 2' is a vertical section taken on a plane at right angles to the sectional plane of Fig. 1, and Fig. 3

is a horizontal section on line 3, 3, Fig- 2.

Similar letters of reference indicate corresponding parts. throughout the different figures.

Referring to the drawings, f re resents. the spindle of my improved fly-bal governor, which is geared to a prime motor of any kindand wh1ch follows the speed-changes of. the same. The spindle f is provided with a central bore f at its u per end and with slots 1) at opposite sides 0 the bored out portion. To the bored out upper end of the spindle f is ap lied the conically-fiaring bottom-plate 0 0 a cylindrical casing or shell 0, which bottom-p ate is provided with a central hub 0 adapted to be screwed or otherwise attached to the spindle, and with a circumferential rim 0 to which the rimmed lower end of the bod} or-main ortion c of the casing or shell 0 lsattached y means of fastening screws 0. The to of the casing or shell is made conically bottom-plate, and also provided with a central hub 0 into which is screwed the threaded pin 0? for maintaining in position-a capplate e, which can be adjusted higher or lower by means of the threaded pin, which latter is provided with a square or other head at its outer end forfacilitating the adaring, like the justment of the cap-plate by means of a wrench.

At the interior of the'shell, and at diametrically-opposite points of the same, are

arranged two knife-ed ed fulcra g, which are attached by means 0% fastening screws 9 to the inner circumference of the bottom: plate of the casing or shell '0, and which engage the recessed apexes of two angular flyball levers h, which are provided with flyballs of the usual size at their upper ends and which are pivoted at the inner ends of their lower arms to the upper ends of links a, a. The links a, a are arranged beside each other and extended into the bored end ofthe spindle f,"their lower ends being connected by a transverse pin 12 with a sleeve 6- which is provided with an exterior grooved collar 6 in which a ring r is placed counterbalanced directly by the springs 8,

without being transmitted to the pivot-pins of the links a, a. The resultant of the centrifugalforce and the pressure of the springs passes to the fulcra g, g without creating any appreciable friction between the levers and the fulcra. This arrangement insures a very sensitive and effective governor. The. knife-edged fulcra are preferably made of steel so as to stand the wear to which they are exposed by the oscillations of the fly-ball levers. The casing or shell, and the fly-ball levers rotate together, and the speed of the motor is regulated through suitable mechanism actuated by the movement of the flyball levers as they assume the positionresulting from the centrifugal force and the force of the springs on. the fly-ball levers.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

,-l. A fly ball governor comprising a rotatable spindle, a sleeve sliding on the same, fly-ball levers provided with weights at their upper ends, a casing, o shell inclosing the fly-ball levers, fulcra at diametrically-opposite points on the base of said casing or shell, a cap-plate supported in the upper part of thecasing, separate counter-balanclng springs inter osed between the lower arms of the fly-ba 1 levers and the cap-plate, and means connecting the fly-ball levers with the movable sleeve on the spindle.

2. A fly-b'all governor comprising. a ;ro-' tatable spindle having a bored out .upper end, a sleeve sliding on said spindle, a casing or shell attached to the spindle, fulcra at diametrically opposite points on the base of said casin or shell, fly-ball levers swinging on said fu era and rotating with the splnda and shell, a cap-plate supported in the upper part of said casing or shell, separate counterbalancing springs interposed between the lower arms of the fly-ball levers and the capplate andpivotlinks extending into the bored out end of the s indle and connecting the lower arms of the y-ball levers with the movable sleeve on the spindle. V

3. A fly-ball governor comprising a rotatable spindle carrying a casin a sleeve movable on the spindle, opposite y disposed fulcra in said caslng, angular fly-ball levers swinging on said fulcra, a cap-plate supported in the upper part of the casing, sep-' arate. counterbalancing springs interposed between the cap-plate and the inner ends of the fly-ball levers, and means connecting the fly-ball levers with the sleeve movable on the spindle.

4. A fly-ball governor comprising a 1'0- tatable spindle, a sleeve slidable thereon, an

v gular fly-ball levers having weights at their upper ends and circular recesses on the upper face of their inner ends, a casing supported on said spindle and carrying fulcra on which the fly-ball levers are pivoted, a cap-plate supported in the upper part of said casing and having circular recesses in its lower face, counterbalancing-sp-rings interposed between the recesses of the cap-plate and the recesses interposed between the recesses of the capshell inclosing' the fly-ball levers and secured to the rotatable spindle, a fulcra at oppositely disposed points on the base of the 5,

casing, a cap-plate supported in the upper part of the casing and having a pair of circular recesses in the lower face thereof, counterbalancing-springs interposed between said levers and said ca -plate with their 61 ends seated in the circu ar recesses of the same, and. means connecting the fiy-ball levers with the sleeve movable on thspindle.

6. A fly-ball governor comprising a rotatable spindle having a bored out upper end, a sleeve slidable on the spindle, a casing attached to the spindle, fulcra at opposite points on the base of the casin angular fly-ball leversvswinging on said ulcra and having Weighted upper ends, and circular recesses on the upper faces of theirinner ends, a cap-plate carrled in the 'upper part of the casing and having a pair of circular recesses in its lower face, 4counterbalancing-springs plate and the recesses of the fly-ball levers, and pivot-links extending into the bored outend of the spindle and connecting the inner ends ofthe fly-ball levers with the sleeve slidable on the spindle.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

MAX HAEBERLEIN.
