FLY-BALL GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 766,615, dated August 2, 1904. Application filed February 11, 1904. Serial No. 193,152. No model.)

To nil whom it HUI/Z] concern.-

Be it known that I, Max HAEBERLEIN, a citizen of the Empire of Germany, residing in Heidenheim-on-the-Brenz, in the Kingdom of 'urtemberg and Empire of Germany, have invented certain new and useful Improvements in Fly-Ball Governors, of which the following is a specification.

This invention relates to improvements in fly-ball governors.

Fly-ball governors are subjected to inherent disadvantages, which in operation make them unsatisfactory for sensitive regulation. Among the causes giving rise to this lack of 5 sensitive regulation are the friction of the joints and the friction of the collar movable on the spindle connected with the regulatingtrain, which friction is considerably increased by a tilting effect of the collar. This last objection takes place especially with elbowlever governors having a centrally-arranged pressure-spring, inasmuch as the spring does not exert an equal pressure on the collar, whereby a tilting effect of the collar is caused,

2 5 which is increased by the fact that the spring has a tendency to kink in the lateral direction. This kinking effect is also caused by the fact that in the manufacture of fly-balls it seldom occurs that the same are exactly equal 3 in size and in weight, whereby each of the flyballs has a different centrifugal force. In the equalization of these unequal forces the diffcrence between the same is transmitted by the collar from one weight to the other,where- 5 by an additional tilting effect of the collar is caused, so that a clamping of the collar on the spindle, and thereby a diminution of the sensibility of the governor, is produced.

The invention has therefore for its object .0 to provide a governor intended to produce an accurate rectilinear guidance of the collar, so as not to be subjected to the tilting effects and attendant disadvantageous influences referred to; and for this purpose the invention 5 consists of a fly-ball governor which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation, partly in vertical central section, of my improved governor. 5 Fig. 2 is a vertical transverse section on line 2 2, Fig. 1; and Fig. 3 is a plan view of Fig. 1, partly in horizontal section.

Similar letters of reference indicate corresponding parts.

Referring to the drawings,f represents the governor-spindle, provided with a central bore b and a transverse slot 6 On the spindle f is movable a collar 6, provided with a ring 0, adapted to be connected with the regulatingtrain. The collar Z) is provided with a transverse rod t, to which is pivotally connected a link g, in turn pivotally connected with a similar rod (0 of an auxiliary piece or member a. This member a is suspended, by means 5 of links 9', from the lower arms of the weighted elbow-levers d, which are pivotally supported by bracket-arms m of a supportingframe seated on and rotatable with the spindlef. 7

The effect of the difference in the centrifugal forces of the fiy-balls is in the construction described not transmitted to the collar 7), but to the auxiliary piece or member a. This piece is therefore subjected to the tilting caused by the dilference in the centrifugal forces, which is furthermore increased by the influence of the spring 0, interposed between the member a and adjustable cap a acting directly on it. The cap a is adjustably sup- 8O ported by the frame /t, rotatable on the spindle f. It assumes, therefore, owing to the links connecting it with the elbow-levers, always a position corresponding to the force exerted thereon, which variation in position 5 is not, however, transmitted to the collar movable on the spindle and connected with the regulating-train. The auxiliary piece a may therefore assume a slight inclination without exerting thereby by its inclined posi- 9 tion any tilting effect or similar disadvantageous influence on the collar connected with the regulating-train. The member (1, suspended from the elbow-levers of the suspension-links, transmits, by means of the connecting-links g solely, a rectilinear movement to the collar on the spindle, and thereby causes the movement of the collar on the spindle to riations.

be attendant only with the friction necessary for this movement and not subject to the tilting effect referred to. The slightest ascending or descending movement of the suspended member will be transmitted to the collar on the spindle, which is, owing to its comparatively small friction, susceptible to these va- The sensibility of the regulation may thereby be greatly increased.

I claim as new and desire to secure by Letters Patent l. A fly-ball governor, comprising a rotatable spindle, a collar movable on the same, weighted elbow levers rotatable with said spindle, a member pivotally suspended from said elbow-levers, and a link pivotally connecting said member and collar, substantially as described.

2. A fly-ball governor, comprising a rotatable spindle, a collar movable on the same, a supporting-frame rotatable with said spindle, elbow-levers provided with fly-balls pivotally supported by said frame, a member suspended from the inner arms of the elbow-levers, a

spring interposed between said member and the upper part of the frame, and means pivotally connecting the member and the collar, substantially as described.

3. A fly-ball governor, comprising a rotatable spindle, a collar movable thereon and adapted to be connected with a regulatingtrain, and provided with a rod, a supportingframe, weighted elbow-levers, a suspende member also provided with a rod, means pivotally connecting said member with the inner ends of the elbow-levers, a spring interposed between the member and the upper part of the frame, and a link connecting the rods of the member and the collar, substantially as described.

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