Specification of Letters Patent.

Patented Oct. 5, 1915.

Application filed May 15, 1914. Serial No. 838,850.

principal object ofthe invention is to provide an improved type of frame for mounting the actuating mechanism and to also provide improved means for engaging the tub of the churn and securely hold the tub in place.

Another object of the invention is to so construct the tub engaging means that it may be used with tubs of various heights and to also so construct this tub engaging means that it may be securely held in a locked position about the tub.

This invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the improved churn; Fig. 2 is a front elevation of the improved churn; Fig. 3 is a vertical sectional view through the tub and tub holding means; and Fig. i is a transverse sectional view taken along the line t-t of Fig. 2. p

The standards 10 and 11 are supported by the supporting legs 12 and carry the cross bar 13 which hasits outer end portion provided with a slot 14 and forms a guide. These standards 10 and 11 are braced inter mediate their height by the braces 15 and have their upper end portions provided with bearings 16 in which the driving shaft 17 is rotatably mounted. This driving shaft 17 extends beyond the standard 10 and carries a. crank handle 18 by means of which the driving shaft may be rotated. It is of course obvious that if desired the driving shaft 17 may be rotated by any other suitable mechanism. The driven shaft 19 is rotatably carried by the standards 10 and 11 above the braces 15 and carries a pulley wheel 20 which i positioned beneath the large pulley wheel 21 carried by the driving shaft 17 so that when the driving shaft 17 is rotated the driven shaft 19 may also rotate, rotary motion being transmitted from the pulley wheel 21 to the pulley Wheel 20 by means of the belt 22. It is also obvious that if desired pulley wheels 20 and 21 could be provided with teeth which would mesh so that rotary motion could be. transmitted from pulley wheel 21 to 20. A. disk 23 is rigidly mountedupon the outer end portion of shaft 19 and carries a link 24 which is pivotally andeccentrically connected with the disk by means of pin 25 so that as the disk 23 rotates the link 2% will be moved vertically. The lower end of the link 24 is provided with a bearing 26 in which a pin 27 is rota tably mounted, the pin 27 being slotted so that the upper end of the dasher 28 may be passed into the slot and releasably held in place by means of set screw 29. The tub 30 which is provided with a cover 31 through which the dasher '28 passes is placed beneath the outer end portion of cross bar 13 and is engaged by the clamping arms 32 which have their inner ends pivotally connectedwith the bracket and their outer ends releasably connected by latch 34. This latch 34 is pivotally connected with the finger 35 by one of the clamping arms 32 and may be easily swung to engage the finger of the second clamping arm as shown in Figs. 1 and 4. In order to hold the cover in place there has been provided hooks 36 which pass through openings formed in the clamping arms 32 and are releasably held in place by means of set screws 37 From the above description the operation of this churn will be readily understood. The cream is first placed in the tub 30 and the tub is then put in the position shown in Fig. 2 and the clamping arms secured about the tub by means of latch 34.

'The dasher which had previously been passed through the cover is then inserted in the tub with the cover resting upon the tub and the cover engaged by hooks 36 which are lowered to tightly engage the cover and secured in the lowered position by the set screws 37 The upper end of the dasher is then connected with the rotatable pin 27 by means of the set screw 29 and the churn is ready to be operated. By turning the handle 18, driving shaft 17 will be rotated and rotary motion will be transmitted to the driven [schaft 19. The disk 23 carried by driven shaft 19 will rotate. and will move link 24-. vertically thus reciprocating dasher 28 and causing the cream in the tub 30 to be churned into butter. As soon as the churning is finished the dasher is released from pin 27 and the clamping arms 32 and the hooks 36 are released so that the tub may be removed and the cover and dasher removed from the tub. The butter and butter milk can then be removed from the churn and the tub, cover and dasher then Washed and either put away or reconnected with the operating mechanism as already described.

What is claimed is 1. A churn comprising a frame, tub holding means carried by said frame, a driven shaft carried by said frame, a link pivotally and eccentrically connected With said driven shaft and provided with an eye adjacent its free end, a pin rotatably mounted in said eye and having its outer end portion slotted to receive a dasher, and means for rigidly securing a dasher in the slotted end portion of said pin.

2. In a churn, a frame, tub engaging means carried by said frame and including means for encircling the tub and means for engaging the cover of the tub to hold the cover in a closed position, rotatable operating means carried by said frame and including an eccentric disk, and a link pivotally connected With said eccentric disk and provided with pivotally mounted means for engaging a dasher.
