UNITED STATES PATENT OFFICE.

JOSEPH E. EARNEST, JR., OF REED CITY, MICHIGAN.

CHURN.

To all whom t may concern.'

Be it known that I, JOSEPH E. EARNEST, J r., a citizen of the United States of America, residing at Reed City7 in the county of Osceola and State of Michigan, have invented certain new and useful Improvements in Churns, of which the fo-llowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in churns and its object is to provide certain new and useful features in the construction and arrangement of parts all as hereinafter more fully described reference being had to the accompanying drawings, in w'hich Figure 1 is a perspective view of a device embodying the invention; Fig. 2 an enlarged vertical section of the same; Fig. 3 a plan view of Fig. 2 with parts broken away to show the construction; and Fig. 4 a plan View with the cover removed.

As shown in the drawing 1 represents a suitable cylindrical receptacle or body preferably formed of sheet metal having a downwardly extending bottom flange 2 to receive a suitable base 3 which extends upward within the flange to support the bottom 4 of the receptacle. Secured to the base 3 are suitable legs 5 for supporting the churn at the proper height from the floor. Near t-he upper end of the receptacle the same is provided with a hoop or ring 6 around the outer side thereof and the upper edge of the body is formed over the upper edge of this ring to prevent the ring from coming off and to strengthen the upper edge of the body. This formed over edge above the ring 6 is provided with grooves 7 in opposite sides of the receptacle to receive the ends of a cross strip 8 which is inserted therein by springing the upper edge of the receptacle and the strip. This strip is provided with holes to receive the upper ends of vertical shafts 9 of paddles for stirring and churning the cream in the receptacle. Secured to these shafts are transverse strips 10 to the outer ends of which are secured blades 11 and the lower ends of the shafts 9 are reduced to engage sockets 12 in the bottom 4 of the receptacle. 13 is a suitable cover having a flange to engage the upper rim of the receptacle and this cover is detachably secured in place by rods 14 having hooked lower ends to engage beneath the ring 6 and screwthreaded at their upper ends to receive thumb nuts 15, the rods passing Specification of Letters Patent.

Patented Aug. 23, 1910. serial No. 562,231.

through slots 16 in opposite sides of the cover with the thumb nuts engaging the upper surface of the cover.

Bolted to the upper side of the cover are two bearing brackets 17 for a transverse shaft 18 which is provided upon one end with a crank handle 19 for turning the same and secured upon this shaft inside the bearing brackets are tw'o gears 20 adapted to engage pinions 21 detachably secured to the Lipper reduced ends 22 of the paddle shafts 9 which extend upward through openings in the cover. A transverse strip 23 extends across the cover between the bearing brackets 17 and the reduced upper ends of the paddle shafts extend upward through openings in this strip and are provided with a further reduced end forming a shoulder to engage the lower side of the pinions. Each shaft is provided with a fixed transverse key 24 to engage a transverse slot in the pinion and thus detachably hold the pinion to turn with the shaft. The strip 23 and cover are also slotted for the passage of the keys 24 so that the shafts may be withdrawn from the cover or the cover lifted off.

A block 25 is pivotally attached by a bolt or screw 26 to the upper side of the strip 23 and this block is recessed at 27 at each end to receive the pinions 21. These pinions are thus incased in the block and when the cover is removed and the shafts 9 thus disengaged from the pinions said pinions are held in place to be re'engaged with the shafts by said block. If it is desired to remove the pinions the block 25 may be turned on its pivot transversely of the strip 23 moving the pinions out of engagement with the gears 20 and from over the strip 23 where they may drop downward out of the recesses in the block.

An opening is provided in the cover at one side of the strip 23 so that the operator may look into the churn and have access thereto without removing the cover and this opening is clos'ed by a suitable disk 28.

The parts are quickly and easily assembled by first placing the paddles within the churn body with their lower reduced ends in engagement with the sockets 12. The transverse strip or bridge 8 is then slipped over the upper ends of the paddle shafts and sprung into the grooves to hold the Lipper ends of the shafts in proper position, the cover with its assembled gearing is then placed upon the body and the reduced upper end the paddle shafts "engagedY thereby with the openings in the cover and their keys Y with the slots in the pinions which are held in proper position for such engagementby the block 25. The cover is then made fast vby the engagement of the hooks 19 Y with the ring y6 .and the turning of the thumb nuts v 15. Power may be applied to the shaft 18 to turn the gearing and actuate the paddles,

vby the crank handle I9 or bymeans of a pulley 29 secured to the opposite'end of the shaft.

Having thus fully described my invention what I claim is 1. The combination'of va receptacle, ver'- tically extending parallel paddle shafts in said receptacle, a cover to close the upper end of the receptacle a strip extending across said cover, said cover and strip having openings through which said shafts extend, pinions adapted to be detachably engaged by the upper ends of the paddle shafts when the cover is placed upon the receptacle, a

Ablock pivotally attached intermediate its lends to the strip and provided with recesses at each end to receivethe pinions and hold the same, said block being adapted to bev turned on its pivot out of alinement with said strip to release said gearsfrom said recesses, a shaft mounted in bearings on the cover, gears on the shaftl to engage the pinions, and means for turning the shaft.

2. The combination of a receptacle provided with grooves at each side near its upper end, a ring embracing the receptacle adjacent to said grooves, a Hange extending downward Vfrom the lower end of the receptacle, a base engaging the flange and extending upward within the same to support cover, bearing brackets secured to the cover,

a transverse shaft mounted in said bearing brackets, gears secured to said shaft, a transverse strip extending across the cover between the brackets and provided with openings through which the upper ends of the Vpaddle shafts extend, pinions engaging the gears and adapted to be detachably engaged by the upper ends of the paddle shafts, and a block pivotally attached to the saidstri and recessed at each end to receive sai pinions.

In testimony whereof I afiX my signature in presence of two witnesses.
