' Application filedMarch 16, 1922.1 Seria1 No.;54 4 ,31 -0.

The invention relates to combined churn and butter-Workers of the type comprlsing a churn drum rotatably supported at its ends and carrying 16VOlUbl6.WO1l(1I1g IOllS, and

relates more .particularly to the operating and supporting means for the drum and the rolls. i

Churn drums are commonly constructed of Wood to the Woodenheads of Which are secured gudgeons fortheir operative sup: port. The Working rolls also are commonly journale'd in the Wooden heads. tortion ofthe ClFU111,'Cl11G to the action ofits liquid contents affects the alineinent of the gudgeons and also of'the roll,beari1igs,.and causes much wear, noise and loss of power. The object of this-invention isto provide an improved gudgeon supporting construc-. tion including a final gear and rigidly posi- 'tioned end bearings for -the;'working roll ournals.

Other objects and advantages Will be ap-- parent in the following detailed description. of a. preferred embodiment ofxmy invention Which I haveillustratedin the accompanying drawings l In the drawings Fig. 1 isaplan view of a preferred construction of churn and butter-Worker in which only the end'porti'ons of the churn drum are shown;

Fig. 5 is a horizontal section takenon the plane of'the line 5-5 in lj ig. 4. a In the present embodiment, the frame of the machine'comprise's'a front standard 1 and a. rear standardQJ'igidly connected at the top as by a spacer tube 3 and rod 4, the latter carrying end cap nuts 5 Whichclamp the standards. I 'standardsare preferably rigidly spaced by a pair of side stringer tubes *6 suitablv clamped in the legsof the standards as at Forward extensions of the stringers G carry an outer bear ng support 85 and an inner bearing .support 9 which the driving mechanism.

' The drum or body of the churn consists The dis-v V for 8 is a longitudinal vertical'section' The lower portions of the accommodate of-a cylinder 10l1avingheads11 and l2,'and

bindinghoopsdlfito secure the usual stave construction. :A door 14 gives access; to the interior of-the churn. To the front head ll'ofthe drum is fixed 'afsectional gudgeon structure comprising a flanged base section 15v rigidly secured to thehead; as; by bolts 16, and an outer spider section 17 providing a ournal 18 alined with the axis of the drum and having radial arms 19 supporting 'a ring gear 20. The spider,- journal and gear comprising theouter section 17 preferably are of integral construction rigidly secured to concentric pro ecting portions-21 of the base 15; as by bolts 22. Thisseetional construction facilitates the manufacture'and assembly of the gudgeonstructure.-

a p As illustrated hereiii' the journal; 18 is automatic ring 25; 4 V 1 The ring gear; 20 and thereby the churn drum, is driven by a pinion 26 rigidly mounted'i-on a shaft 27; rotatably' supported I v i at its ends n bearings 28 and29 in the standardnl and outer-bearingv support, 8 respectively. Adri've pulley 30 is mounted onthe .opera'tively: supported' in a bearing sleeve f 23 mounted in an appropriate bearing bo x Ziformed in the standard l andconstructed lubrication fbyi oiling outer portion of thesha'ft' 27 and is proon the shaft. v

The inner, periphery of the pulley drum suitable clutch device carried bytheshaft. 27 and'herein illustrated ascomprising-one ormore' shoes 32 pivoted atone end on'arms extending from a hub 34. A shift collar 35 splined on the hub 34 serves to operate sets of toggle members of Well'known con- :SCI'UCUOH which selectively force the shoes 32 into frictional oontactwith the pulley. The collar 35 may be annularly grooved to receive a pair of pins 36 carried by a shiftmg lever 37. pivoted at 38011 a bracket mounted on the-inner bearing support 9.

The hub 34:;is fixed ,onthe outer end of a sleeve 39v freely. rotatable on the shaft 27 and extending inwardly from'the pulley hub through the inner bearing support 9, the latter being provided with a, suitable bearing videdwith ahub bearing31' freelyrotatable 85 i relation to the shaft 27.

42, the latter having a hub 13 keyed in fixed The friction member 41 may be operated to grip the drum 40 by means of the -pivoted cam finger 1 1 controlled by the beveled end of the sliding collar 15. The latter may be operated to engage or disengage the clutch member by the lever 46 pivoted on a bracket 47 mounted on the standard 1, and having a yoke carrying a pair of pins 48 in engagement with an annular groove in the collar 45. It will now be apparent that with the operative engagement of the two clutches described a direct drive is established from the pulley 30 through the shaft 27 to the pinion 26, and gives the higher speed desirable in the churning operation. I

* As illustrated herein the pulley 30 is provided for an initial drive by belt, but it will be obvious that a sprocket or gear may be substituted for the pulley to accommodate a chain or gear motor drive, having associated therewith if desired a friction drum for cooperation with the clutch shoes 32.

For the butter working operation lower speed is attained by means of back gearing and another clutch. A shaft 49, having suitable end bearings supported in the standard 1 and in the inner bearing support 9, carries a fixed gear '50 permanently in mesh with a pinion 51 preferably integrally formed on the sleeve 39. carries a fixed pinion 52 permanently in mesh with a gear 53 mounted for free rotation on'the shaft 27. The hub of the gear 53 is axially extended to form a clutch drum 5 1 with which is 'operatively associated a clutch construction similar to that last described and controlled by the finger 55 and the shaft 27 while the back gears carried by the shaft 19' idly rotate the gear 53. WVhen it is desired to operate at butter-working speed, thecollar 4:5 is shifted to engage the rear clutch and release the front clutch,

whereupon the gear reduction of the back gears is availed by transmission through the pinion 51:, gear-5O, shaft 49, pinion 52, gear 53 and the now engaged clutch hub 55 to the shaft 27 and drive pinion 26.

For the operation of the butter-working rolls I have provided a shaft 57 supported at'its front end in a suitable bearing 58 mounted in the upper portion of the inner bearing support 9.

The shaft 19 also .gear 65.

The shaft 57 is rearwardly supported in a bearing formed in the gudgeon journal 18 and extends axially therethrough to an end bearing 59 suitably secured to the head 11 of the cliurn.

The forward portion of the shaft 57 carries a sliding gear 60 freely rotatable on the shaft and permanently meshed in driven relation to the back gear 50. The forward end of the hub of the gear 60 is diametrically recessed to form a pair of laterally opening pockets adapted to receive the cross pin 61 fixed in the shaft 57 and by which the shaft is driven when engaged. The gear 60 may be shifted without disengagement from the gear 50 to selectively engage or disengage the pin 61 by meansof a shifting yoke 62 engaging an annular groove in. the gear hub, the yoke being longitudinally slidable on a bridge member 63 connecting the inner bearing support 9 with the stand ard 1. The yoke 62 may be operatively controlled by a hand lever 64 pivoted on a lat eral extension of the member 68.

ltearwardly of the gudgeon bearing, the shaft 57 carries a fixed gear 65 by which the working rolls are driven. The working rolls 66 (Fig. 5), of which four are illustrated herein,1 are journaled at the rear of the churn in suitable bearings carried by the plates 68 fixed in the rear drum head, and are supported at their front ends by shafts 67 extending through suitable packing glands mounted in the front drum head. The latter comprise a gland 69 countersunk in the head and secured thereto as by bolts 70. A gland nut 71 is removable outwardly along the shaft 67. I p i The forward ends of the shaft 67 are journaled in bearings 72 provided in a pair of the arms 19 forming part of the gud 'eon and ring gear supporting structure. Rear-wardly of the bearings 72 and laterally alin-ed with the gear 65, a gear 73 is fixed on each of the roll shafts 67, the inner pair of gears 73 meshing with the gear 65, and the outer pair meshing respectively with the inner pair of gears. The base section 15 of the gudgeon structure'is constructed with laterally open walls to accommodate the. gears 7 3.

By disengaging the gear 60 from the pin 61, the former will run free on the shaft 57 in the churning operation, and the rolls 66 will remain in, stationary relation to the churn drum. Upon engagement of the gear 60 with the cross pin in the shaft 57, the

several rolls are operatively rotated by their gears 73 in driven mesh with the central It will now be apparent that the construction herein provided assures a fixed alinement and spacing of the end bearings of the roll shafts, thus maintaining the rolldrivmg gears 111 smooth running relation unaffected by the distortions which may occurseinbling the gears orother of'the driving members.
