PAUL PUTNAM, WHITE PLAINS, KENTUCKY.

Application filed July 14, 1920. Serial No. 396,068.

To all whom it may concem:

Be it known that I, PAUL PUTNAM, a citizen of the United States, residing at White Plains, R. F. D. 1, in the county of Muhlenberg and State of Kentucky. have invented new and useful Improvements in Churns, of which the following is a specification;

The object of the invention isto provide relatively simple and efficient construction of motor driven operating mechanism for churns and simple means whereby the speed of movement of the same may be readily and conveniently regulated and wherein the op erating parts are so mounted and supported as to permit of the independent removal and re-positioning of the churn tub or receptacle as may be required in connection with the emptying and re-filling of the same and also to provide means whereby the movements of the operating mechanism may be readily checked as required from time to time during the re-adjustment of the churn tub or receptacle for the purposes indicated and with these objects in view, the invention consists of the construction and combination of parts, the preferred embodiment of which is shown in the drawings wherein Figure 1, is a front view of the apparatus.

Figure 2,'is a rear view of the same.

Figure 3, is a side view.

Figure 4, is a plan view.

Figure 5, is a vertical sectional view taken on the plane of the axis of the driven head.

Figure 6 is an elevational view of the driving spring and its housing.

The operating mechanism which includes a driving spring 10 and a rotary driven head 11 with intermediate gear train 12 for communicating motion from the former to the latter and a frame 13 consisting of front and rear frame members 14 and 15 and intermediate member 16, the lower ends of the front and rear frame members constituting feet between which is arranged a base 17 constituting a seat for the churn tub or receptacle 18. The front and rear frame members include transverse bars 19 and 20 and the intermediate frame member includes a frame member 21 while supported by the front, rear and intermediate frames below the plane of said frame members is a tank 22 to catch any grease which may drip from the operating mechanism and'prevent.

the same from falling into the churn tub or receptacle located in the base.

The transverse frame members are provided with hearings in which are mounted the operating elements and driving mechanism. The driven head 11 is provided with a socket in which is fitted a stem 23 of a dasher 24. preferably having a cross sectionally triangular stock member 25 provided in its faces with diagonally disposed slots in which are fitted the inclined blades 26. The dasher stem is secured in the head 11 by means of a set screw 27 or the equivalent thereof.

The motor spring is operatively arranged in a housing 28 and is connected with the driving gea 29 meshing with the pinion 30 mounted on the shaft 31 which carries a gear 32 in mesh with the pinion 33 which through a bevelled gear 34 conveys rotary movement 7 to the bevel pinion 35 secured to the shaft 36 which carries the driven head. Said shaft preferably serves to actuate the governor 38 having a worm and gear connection with the shaft 36 and in the construction illustrated said governor is ofthe centrifugal type and is connected with the sleeve 39 carrying friction disk 40 for movement relative to brake blocks 41 to limit the speed of rotation of the driven shaft. The brake blocks are preferably carried by an arm or a yoke 42 which is pivotally mounted upon a swinging bracket 43 to which is attached a feed screw 44 threaded in a bracket 45 and provided with a terminal disk 46 for manual operation. may be adjusted toward and from the plane of the friction disk to vary th speed of rotation of the driven head. The arms of the yoke are preferably of yieldable or resil ient material. I 4 The required tension is applied to the motor spring by means of a shaft 47 provided with a crank handle 50 and carrying a gear 19 meshing with a gear 48 which is mounted on a shaft 47 to which one end of the spring 10 is connected. Reverse or retrograde movement of the shaft 47' is precluded by means of a ratchet 51 carried by the shaft and engaged by a pawl or dog 52. The driving gear 29 is carried by the housing 28 which assists the motor spring in the operation of the mechanism and which is Consequently the brake blocks 7 V provided with peripheral ears or projections 53, while disposed in operative relation with the housing is a rock shaft 5a having a crank 55 adapted to be arranged in engaging relation with the stop cars 53 when the operating handle 55 is moved in the direction indicated by the arrow in Figure l.

The lever operates in relation to a ratchet bar 56 and is provided with a dog 57 for engagement therewith. Obviously when the mechanism is to be operated it is only necessary to shift the lever to a position by which the loop or crank of the said shaft is disposed out of engaging relation with said ears 53 of the spring housing whereas the opposite movement of the same will serve to check the rotation of the housing until another operation is required.

When disconnecting the churn tub or receptacle to permit of its removal from the frame for filling or emptying purposes, it is only necessary to detach the dasher stem from the socket after having checked the rotary movement of the head through the means above indicated, and upon the replacement of the tub Or receptacle and the reengagement of the dasher stem, the resumption of the churning operation may be accomplished simply by releasing the motor spring housing. Also it will be obvious that the speed of movement of the driven head will be regulatable by the adjustment of the yoke which carries the brake blocks as hereiirbefo-re explained, to suit the conditions under which the churn is being operated.

The invention having been described, what is claimed as new and useful is 1. A power mechanism having a revoluble member by which motion is communicated, the said member being provided with spaced peripheral ears throughout its circumference, a rock shaft having a looped crank arm arranged in transverse spanning relation with the periphery of said member for engagement with the ears thereof, an operating lever for said rock shaft, and means: for securing said lever in adjusted positions. 2. A power mechanism having a revoluble housing and actuated spring contained therein tending to move the housing in one direction, the periphery of the housing being provided with spaced peripheral ears throughout its circumference and extending transversely across its peripheral face, a rock shaft having a looped crank arm arranged in transverse spanning relation with the periphery of said housing, and an operating lever for rocking said shaft to move said looped crank arm into and out of engaging relation with said cars.

In testimony whereof he affixes his signa ture.

PAUL PUTNAM.
