To all whom it may concern Be it known that I, HERBERT S. VVILsoN,

' a citizen of the United States, residing at tained a predetermined speed; otherwisethe proper separation of the liquid into ts con- 1 stituent parts willnot be obtained.

A further object of the invention is the provision of means to regulate such flow which shall be simple in construction, economical to manufacture, composed of few parts, and unlikely to require iepairs.

In the accompanying drawings, I have illustrated .a preferredembodiment of this invention applied to a cream-separator, but it is to be understood that the invention is susceptible of employment in association with devices other than cream-separators.

In these drawings,Figure 1 is a fragmentary side elevation of a cream separator supplied with my improved governor for controlling the feed of liquid to the ma chineyFig. 2 is a view of the same mecha-. n'isrn at right angles to that of Fig. 1, and illustrates some or" the parts in section; F igs. 3, 4 5 and 6 are detail views illustrating the structural features of the speed governor.

,By referring to the drawings, it will be observed that I have illustrated my improved governing device in'connection with a cream-sceparator of the usual-centrifugal type operated by means of a handle 10. asso- .ciated with a shaft 11 geared to the other parts of the mechanism to obtain'sthe high speed of rotation necessary forsecu'ring the proper separation of the milk'into ts component parts. As is customary with ma chines of this character, the one illustrated is equipped with a supply tank 12, from which the milk, when permitted, is adapted flow through a pipe '13 into the top portion '14: of the separator. At its outer end, the pipe 18 is in communication with a ver- Specificationof Letters Patent. Application filed Maren 1s,

tical tube 15- the lower end 16 of which is tapered, as illustrated in Fig. 2. This tube carries internally avalve 17 adapted by cooperation with the tapered portion 16 of the tube to establish and break communication between the tube 13 and the receptacle 14:.

The tube 15 also has Within it a plunger or guide 18 connected to the valve 17 by a stem 19. The upper end of the tube 15 is equipped with a supporting bracket 20, on which is fulcrumed at 21 a lever 22, the end of which, disposed over the tube 15, is connected to the plunger 18 or stem 19 by a link 23, while the opposite end of the lever 22 is connected to a rod v24 having at its upper end a hook 25 adapted to engage a pin 26 at the end of the lever.

The separator shaft 27 projects laterally beyond the base or standard 28 of the machine, extending through an apertured boss 29 on the side of such standard. This shaft has fastened thereto a plate 30, to the opposite ends of which are pivoted, on pins 31,

acted upon by centrifugal force, and when the speed becomes suihciently highto overcome theretr'acting action of the springs 34, the weights will separate, turning on their fulcrum pins 31, 31.

The outer end of the shaft 27 is journaled in a bracket 35, and between such bracket and the plate 30 there is provided a sleeve 36 rotatable with and also slidable on the shaft 27, being secured thereto by means of a key 37 fitting in keywa'ys in the shaft 27 and the sleeve 36. At one end, this sleeve 36- is equipped with a pair of disk portions 38 and 39; between which are accommodated two pins 10, 40, secured to the cars 32 or the two weights 33, wherebythe outward and inward swinging of these weights on their fulcrurn pins 31 causes a longitudinal shifting "of the sleeve 36 on its sup orting shaft 27.

boss portion 42 of the sleeve. One face of this boss section 42 is beveled at43, and at its opposite end the sleeve 36. is provided with an oppositely beveled disk member 44. Be tween these two beveled surfaces 43 and 44 another beveled disk 45 is accommodated,

such disk being cutaway on one side to'pro- Videa flat bearing surface 46. The disk-45 is fastened to the inner 'e'n'dof a shaft 47 rev-f oluble in a'bearing 48 fastened to or forming part of a lateral extension 49 of the bracket 85, At its other end, this shaft 47 has a col:

' lar 5O fastened thereto, to which the lower pivotally connected by a end of the rod 24 is screw '51.

' The operation of this governing 'mecha nism takes place substantially as follows:

Assuming that the supply receptacle 12 is charged "with milk and that the valve 17- prevents the flow of such fluid to the receptacle14 by-coiiperating with the end 16 of the 'tube 15,,it will be obvious that the valve17 should not be perinitted to open until the speed of operatlon of the separator is su'ificiently high to"assure the proper separation of the milk into its component parts. The

operator, by grasping the handle l0 and reason the disk should attemptto turn in such direction as to open the valve 17, its

conical surface would at once contact with the surface 44, cqusing a rotation of the disk 45 in a=directionbto close the valve 17. In

other words, so long as'the speed of rotation is below that which is adequate for the separation of the liquid, the valve 17 will be maintained closed. Aslsoon -however, as,

the proper speed is reached, the outward swinging of the weights 33 in opposition to the retracting action of their springs 34 will, by means ,of the coaction between the pins 40 andthe disks 38 and 39, slide the valve 36 outwardly so as to bring the conical surface 43 into contact withthe corresponding --surface of the disk 45, and, owing 'tosuch frictional engagement, the latter disk will be turned, rotating the shaft 47 sufficiently to pull down the connecting rod 24, rock the lever 22 on its fulcrum 21, and lift the valve 17 permitting the milk to flow from thereceptacle 12, through the pipe 18, into the chamber 14, from which it passes down wardly into the centrifugal separator proper. The valve 17 will be maintained open so long as the speed of rotation'of the machine is up to or above the normal speed referred to. .That is to say, the disk 45, by'

being in direct engagement. If, however,

for any reason, the valve 17 should tend to close while the speed is at or above,the nor- ;lmal, the disk 45 would be turned slightly so as to bring its conicalfas distinguished 1 from its flat surface, into engagement with jthe. surface 43, and by such frictional contact the disk 45 would be turned back so as ;to.maintain the valve open and again re- 'turn the flat surface 46 opposite the conical surface 43. In other words, the valve 17 is mechanically and automatically maintained Q open so long as thespeed is proper. If the speed decreases so as to be below that which fis normal, then the inward movement of'the weights 33 will shift the sleeve 36 inwardly,

so that the disk 44 will engage the disk 45 j and turn the latter through 180 so as to close the valve and bring the flat surface 46 op osite the disk 44 when the valve is closed.

I t should be apparent, from the above description of the construction and operation 1 of this mechanism, that the feed of liquid from the chamber 12 to the receptacle 14 is controlled solely by the speed of operation of the separator, and that the opening and closing of-thevalve 17 is entirely automatic and mechanically accomplished. That is to say, the opening and closing of the valve s secured by the rocking Lof the shaft 47 in one direction or the other, and this turning of the-shaft is accomplished'by bringing one or the other of the conical surfabes 43 or 44 into contact with the disk 45," i-he speed of :rotation of the mechanism determining -which of such conical surfaces shall at that time engage the disk '45, the movements of the members provided with such conical :surfaces being brought about by the action of the centrifugally-controlled spring-retracted weights 33. In order to limitthe v swinging of the collar or member 50 beyond.

the proper points,that is,'to zest-let its fniovement to 180-.-I provide the extension 49 of the bracket 35 with a pair of stop pins 521 and 53, against which the member 50 is adapted to bear in the opposite imits of its oscillation. By employing a di k witn the flat or cut away part, there is=no resistance ofleredby the valve operating mechanism to the turning of the handle by the operator except during the opening and closing movements of the valve. 9 I .W'hile'Ihave herein described this invention as applied to a cream separator, it is to b'e'iu'nderstood that the invention is susceptible of employment in many different arts and relations, andthat the structural fea- -tures of the preferredemhodiment herein disclosed may be modifiedwithin comparatively wide limits without departing from the essence of the invention and without the sacrifice ofanyof its material benefits and advantages.
