CHURN-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed July 30, 1907, Serial No. 386,226-

To all whom it may concern:

Be it known that I, GEoRoE E. SMITH, a citizen of the United States, residing at \Vinnfield, in the parish of Winn and State of Louisiana, have invented a new and useful ChurnOperatin Mechanism, of which the following is a specification.

This invention relates to an apparatus for driving a churn by power, the object being to construct a mechanism which may be attached to a table, shelf or other convenient place, and provided with a power driving device operated by a spring or gravity, to rotate the churn dashers in opposite directions; to so construct and combine the parts that any vessel within reasonable limits may be used in which to churn; an arrange ment of the dashers which will permit their easy removal and change of position on the shafts, and finally a means for removing all the driving mechanism from the support to clean and repair any part.

In the accompanying drawing: Figure l is a side elevation of the improved churn, a portion being shown in section. Fig. 2 is a side view partly in section, partly in elevation showing the arrangement of the parts when used for churning in a larger receptacle than in Fig. 1.

Similar reference numerals are used throughout to designate the same parts.

A table, shelf, or other support is indicated by the numeral 1 to which is secured the footpiece 2 of a ver tical standard 3. The footpiece 2 in the construction shown, comprises an upright cylindrical body from which two fingers 4 and 5 project one above the other perpendicular to the foot piece body. The lower finger 4 is provided with a thumb nut 6 threaded vertically through it. The foot piece is applied in the usual manner and fastened by the tlmmbnut 6. From the top of the foot piece 2 rises in a vertical direction the standard 3 preferably of less diameter than the foot piece.

Mounted on the standard 3 is a cylindrical sleeve 7 fitting snugly on the standard but capable of being raised or turned circumferentially thereon, and having a jam nut 8 for fastening the sleeve in any position on the standard. The sleeve 7 extends a short distance above the standard 1, in the bore of which at the top is placed a short pin 9 projecting downwardly from the bottom and at one end of a laterally extending skeleton bracket 10 which projects out some distance from the sleeve. A thumb nut 11 threaded into the upper end of the sleeve 7 bears against the pin 9 and holds the bracket rigidly in place.

A collar 12 is slidably mounted on the sleeve 7 so as to move vertically thereon, a thumb nut 13 fixing it in any position on the sleeve. Attached to the collar 12 and projecting in a direction opposite the normal position of the bracket 10 are two arms 14 on which the driving motor 15 rests. The motor, to which no claim is made, may be a spring or weight driven motor of any kind, inclosed within a box as shown, where winding post is indicated by 16 and the main power shaft by 17. The motor is strengthened in its connection to the sleeve by a metal strap 18 fastened to each side of the motor case and to a bar 19 secured to the sleeve just below the thumb nut 11. An electric motor may be used if desired.

Turning in horizontal bearings on the brackets 10 is a shaft 20, on one end of which there is keyed a bevel gear wheel 21. On the opposite end above the motor power shaft, is fastened a small spur gear wheel 22 engaging a larger spur gear wheel 23 fixed on the motor power shaft.

The projecting end of the bracket 10 terminates in two arms 24 and 25 through the latter passes a hollow vertical shaft 26 screwed into a small bevel gear 27. A smaller shaft 28 passes through the hollow shaft to the upper arm 25 in which it has a bearing. A bevel gear 29 similar to the lower one 27 is screwed onto the smaller shaft just under the arm 25. These bevel gears are engaged and rotated in opposite directions by the larger bevel gear 21 heretofore described.

Resting on the table or shelf 1 is a vessel for the cream to be churned. When the smallest sized vessel is used the sleeve 7 is lowered until it rests on the foot piece 2 as in Fig. 1, but with a larger vessel, the sleeve is raised as the height of the vessel necessitates. shaft 28 extends downwardly nearly to the bottom of the smaller vessel and the larger shaft 26 about half way down. On each shaft within the body is slidably attached a dasher 30, each dasher consisting of a hub 31 to which two paddles 32 are fastened on opposite sides of the hubs. The hubs may be raised and lowered on their respective shafts and fixed by a screw 33.

Adjustably mounted on the shaft 26 is a plate 34 having a hub for a set screw 35. This plate has a diameter sufficiently great to cover the largest vessel that can be used. The set screw is turned back and the cover raised on the shaft until the vessel is in place and the dashers adjusted, after which it is lowered to cover the vessel and then fixed to the shaft by the set screw 35. It will thus be seen that whatever the size of the vessel used, the one cover will be sufficient.

Having thus described the invention what is claimed is: j

1. A churn operating mechanism comprising a standard adapted to be removably attached to a suitable support, a sleeve 'movablc on said standard and having means for fixing it thereto, a horizontal bracket removably attached to the top of the sleeve, a horizontal shaft turning in bearings on said bracket, a removable motor carried by the sleeve, and gearing between the motor and shaft.

2. A churn operating mechanism comprising a standard, a vertically adjustable sleeve thereon to permit the use of vessels of different sizes in which to churn, an overhanging bracket projecting; laterally from the top of said sleeve and carrying a horizontal shaft, a removable motor on the sleeve and connected to said horizontal shaft by gearing, a vertical shaft screwed into a gear \vheel meshing at the bottom of a larger gear on the horizontal shaft, a smaller shaft passing through said hollow shaft and screwed into a gear wheel meshing at the top of the gear wheel on the horizontal shaft, a horizontal plate adjustably attached to the hollow shaft, and, a dasher mounted on the lower end of each vertical shaft and vertically adjustable thereon.

A churn operating mechanism comprising a standard having a foot piece with a clamp thereon, a sleeve vertically movable on said standard and having a clamping means for securing it to the standard, a motor, and a horizontal bracket carrying the churn dashers and their ope1 Witnesses .l.
