To all whom it may concern:

Be it known that I, FRANK L. DEOKER, a citizen of the United States of America, residing at Sand Fork, in the county of' Gilner and State of West Virginia, have invented new and useful Improvements in Churns, of which the following is a speciiication.

This invention relates to improvements in chnrns o'J the oscillating-dasher type.

The prim ary object of the invention is to provide a churn having an improved construction of dasher-drive gearing and means for Inountin g the same upon the churn-eover and the latter upon the churn-casing.

Another object of: the invention is to provide a simple and effective detachable connection between the dasher and drive-gearing whereby the dasher may be Conveniently removed for cleaning and withdrawn from the churn-casing, so to be out of the way when it is desired to remove the butter.

With these and other objects in view the invention consists of the novel Construction and combination of parts hereina'lter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a central vertical section of a churn embodying my invention. Fig. 2 is a side elevation ol' the same with portions broken away to better show the construction. Fig. 3 is a detail section through the cover, the pinion, and journal, illustrating the operation in withdrawing the dasher-sten. Figs. 4 and 5 are detail perspective views, respectively, of the upper end of the journal and the dasher-stem.

Referring now more particularly to the drawings, the numeral 1 dcsignates a churncasng, which is preferably cylindrical in form and may be made of Wood, glass, crockcry," or any other suitable material. The mouth of this casing is adapted to be closed by a head or cover 2, provided with a laterally-extending annular fiange 3 to rest upon the upper edge of the casing. The head carries a supporting-hame for the drive-gcaring, tor-med of a pair of parallel brackets 4, having outwardly-projecting horizontal arms 5, and Secured to the cover by screws or other suitable -fastenings 6. The up per end of the casing is 'formed with an annular recess 7, within which tits an annular holding-band 8, said band being forned of two senicircular sections 9 and 10, having their meeting ends bent laterally to form sets of lugs or cars 11. Extending through each of these sets of ears is a pivot-bolt 12, to which is pivoted the lower end of an IL-shaped clamping-bracket 1.3, the said bracket having its horizontal arin arranged to extoud over the horizontal arm 5 of the adjaeent bracket 4 and pro vided with a clamping-screw 14 to engage the same. The vertical arms of the two brackets 13 are ad apted to bear against the edge of the fiange 3 When in clamping position, and the parts 5 of the bearing-brackets 4 serve as wear-strips to snstain the impinging action of the screws 14 to thereby prevent mutilation of the cover. The clamping-brackets will securely hold the head or cover in applied position and permit of its ready rcmoval by simply relaxing the screws and swinging the brackets downward on their pivot-bolts 12.

The upper ends of the bearing-brackets 4 support a horizontal shail t or axle 15, which may consist of a bolt extending therethrongh and held in position by clanping-nuts 16. Looselymounted to oscillate upon said sha'ft is a driving gear-wheel 17, having an operatinghandle 18. The gear is arranged on the shai t adjacent to one of the brackets 4 and is spaced from the adjacent bracket by a sleeve 19, loosely encompassing the sha'ft. The drive-gear 17 meshes with a pinion 20, formed or provided upon the upper end with a hollow journal 21, formed in the cover, which latter isprovided on its upper surface with a bearing-boss 23, on which the pinion 20 rests and turns.

The dasher 24, which may be of any preferred form and material, is provided with a shaft or stern 25, which extends upwardly through the journal 21 and gear 20 and is slidably mounted therein for ready application to and removal therefrom. As shown, the journal 21 is provided above the pinion 20 with diametrically opposite slots 26 to receive a coupling-pin or key 27, carried by the stern 25. This pin coincides in width with the diameter of the stern and is cent'ally pivoted thereto within a slot 28, formed in said stem on a pivot-pin 29.` The construction, therefore, is such that the pin may be swung outwardly from the slot 28 at right angles to the stem and fitted within the notches 26 to connect the dasher for rotation with the journal 21 and pinion 20 and so that upon sliding the dasher upward the key may be swung into the slot 28 to lie wholly within the same, as shown in Fig. 3, thus pernitting the dasher to be slidably withdrawn from the journal.

IOO

IIO

In the operation of the device the Cream to be churned is placed in the usual manner in the casing l, the cover clamped firmly in position, and the handle 18 oscillated to impart a corresponding motion to the dasher. The cover may then be removed and the dasher detached for cleansing and the cover replaced until it is desired to WithdraW the butter. lt desired, after removal of the dasher the cover may be applied and connectcd With one of the clam ping-brackets 13, which Will form a hnge connection, Which Will pernit the cover to be swung back for the removal of the butter When desired. The cover is provided With a sight-opening having a transparent panel 30, through Which the interior of the casing may be viewed When the casing is made of opaque material to determine the progress ot the churning operation from time to time. In the cover is also formed an opening 31, through which Water may be introduced to facilitate the process of churning. This opening may be closed by a plug or other form of stopper 32.

It Will be observed that the churn mechanism is simple of Construction, may be manufactured at a loW cost, and is adapted to be Conveniently operated.

It desired, braces 33 may connect the standard 4, sustaining the greater part of the strain With the cover.

Having thus described the invention, What is claimed as new' is* l. A churn comprising a casing provided With an annular groove, a cover, hearingbrackets earried by the cover and having out- Wardly-eXtending horizontal arms secured thereto, a dasher carried by the cover, gearing associated With said bearingbracket for Operating the dasher, a retaining-band occupying the recess in the casing and composed of sections having their adjacent ends outturned to form lugs, pivot members connecting said lugs, L-shaped bearing-brackets having their vertical arms pivotally engaging said pivot members and their horizontal arms arranged to overlie the horizontal arms of the brackets, and clamping-screws carried by said horizontal arms of the clampingbrackets to engage the arms of the hearingbrackets.

2. A churn comprising a casing, a cover there'for having a hearing-opening, a holloW journal extending through said hearing-opening and provided With a pinion and above the pinion With diametrically opposite slots, drive-gearing carried by the cover for actuating said pinion, a dasher having a stem eX- tending upWard through the journal and pinion and slotted at its upper end, and a key pivoted to fold within said slot and adapted When projeeted to engage the notches in the journal to lock the stem thereto.

In testimony Whereof I afl'x my signature in presence of tWo witnesses.
