CHURN-RECOIL STOP.

Specification of Letters Patent.

Patented Jan. 7, 1919;.

`i'lpplicartion filed July 10, 1916. Serial No. 108,506-

the art to which it appertains to make andl use the same.

This invention relates to butter-Working churnS, and has for its object to provide an elastic lock or stop to support the churn bargathered butter.v The invention involves 'certain improvements in the device fer this purpose shown in the patent to G. J. Kaplan, No. 863,282, issued August-13, 1907, and will be fully hereinatfter described'and claimed, reference being had to the accompanying drawing, in whioh'- v Figure 1 1s a side elevation, showlng a device embodying my invention in disengaged position. Fig. 2`isan end view of the same. Fig. 3' is a longitudinal section otthe stop- .post detached.

' In the operation of butter-working churns having an internal shelf on one side on which 'the' butter. is heaped as gathered, it is necessaryto stop the churn with this shelf in con'- -ve'nient position for the removal of the butter. 1yrlhe churn-barrel is accordingly re- Avolved forward as much as desired, and comlmonl'y more, and the driving clutch disengaged.- Thereupon the weight of the butter, sometimes amounting to half a ton, causes a powerful recoil in the movement of the churn-barrel, which must be caught and held fWith the shelf of butter at the right elevation. In the liuacticaluse of a rigid sto-p (called a lock, in the patent above referred to) frequent breakages resulted, the dog, or the. ratchet, and in some eases even the leg of the churn supporting frame. This in- Ivention is designed to avoid this'diflculty, providing an elastic stop-dog or post., .whereby the initial shock of the recoil is absorbed, and the churn tomes easily to rest.

.Referring now to the drawing, the nu- Ameral 1 denotes thebarrel of a churn, provided with a head 2. To this head is atrel in proper position for the 'removal of the.i

its hold and causing a breakage.

tached a central trunnion 3 journaled 1n a bearing at of the main frame `5. To the churn-head is also attached a large annular spur-gear 6 engaging suitably by gearing not shown with thedriving jack-shaft 7. l

These parts being incidental, need no particular description.

To the web of the gear 6 is secured a short segmentof ratchet 8, the teeth of which pro- ]ect endwise with respect to the churn. By reference'toliig. 2 it will be seen that the teeth are concavo-convex in form, in part to somewhat strengthen them, but mainly to prevent-the head of the post, when it engages them, from slipping sidewise, losing Thepost comprises a number of parts, described as follows: To the upper end of a tubular part 9 is secured, as by a rivet 10 through its shank l1, a ratchet-engaging head 12, having a laterally projecting nose 13 of a shape and size to engage the ratchet between the teeth,and .with its upper face curved as shown in Fig. 3 to correspond with their concavity. Inside this tube is slidably mounted a plunger 14, slotted at l5 to admit a bolt 16 passing through the tube.

Between the upper end of the plunger and the shank` of the post-head is placed a stiff coil spring 1T, which takes the first impact of the recoiling churn. The foot 18 of the plunger is pivoted at 19 tothe frame-leg 20, which is socketed at 21 so as to form a. seat for the rounded end of the plunger, and thus take lall strain from the pivot-bolt. At the 'outer side-of this socket is 'a lug 22.to limit the outward swing of the post, which is a little past its center of gravity. To the inner side of the post-tube is attached an adjustable set-screw 23, whose head abuts against and rides along the outer face of the gear flange Ga, and thus holds the post in the proper position to engage the ratchet teeth, instead oi' the end of the ratchet-plate, or other' part.

To stop the churn in the desired position, the .operator needs only to swing the stoppost over tothe left While the .churn is turning normally, clockwiseas to Fig. 2. When the ratchet is passing its' upper end he shifts the'driving clutch 24;, whereupon the post engages the ratchet and arrests the recoil. In case the ratchet goes clear past the postclaim In a churn-recoil stop, the Combination of a ratchet segment attachable to the churnhead, and a, post comprising a ratchet-engaging head, a tubular body, a plunger slid- 10 able therein and attachable to the churnfralne, the plunger being slotted to receive a retaining bolt, a. bolt passing through said slot, and a spring between the ratchet engaging head and the plunger.

In testimony whereof I affix my signature 15 in presence ot' two Witnesses.
