ALBERT BLAIR, 0F GENESEO, ILLINOIS.

CHURN.

Application filed October 14, 1911.

T 0 all whom it may concern:

Be it known that I, ALBERT BLAIR, a citizen of the United States, residing at Geneseo, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to improvements in barrel or box churns.

The primary object of this invention is to provide a device of this character that will churn the cream in about half the time required through the use of the ordinary barrel or box churn, the condition of the milk, temperature, etc., being equal.

WVith the foregoing and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

In the accompanying drawings :Figure 1 is a side elevation of a churn embodying my improvements. Fig. 2 is a side elevation with the churn tilted at an angle of about fifteen degrees with a vertical plane. Fig. 3 is a central vertical section of Fig. 2. Fig. 4 is a horizontal section taken on the plane indicated by the dotted lines 4-4 of Fig. 1. Fig. 5 is a sectional elevation of a modification, and Fig. 6 is vertical section taken on line 6-6 of Fig. 5, looking in the direction indicated by the arrows.

Referring to the drawings for a more particular description of the invention, the churn body is herein shown in the form of a barrel 1 revolubly mounted at the center between standards 2 of the supporting frame 3. A shaft 4 is bolted at lts inner end to one side of the barrel and is mounted to turn in the upper end of the adjacent standard, the outer end of said shaft being provided with the crank handle 5. A stationary shaft 6 projects inwardly from the other standard and forms a bearing for the disk or plate 7 which is bolted to the opposite side of the barrel and turns on shaft 6. A stationary gear 8 is mounted on the shaft 6, the purpose of which will be hereinafter specified.

A double winged paddle 9 is mounted to turn within the churn body as the latter is rotated. Said paddle is suitably keyed to a shaft 10, one end of which is mounted to turn in a bearing 11 bolted to the inside of the churn body and the opposite end of Specification of Letters-Patent.

Serial No. 654,576.

which extends through and beyond the opposite side of the churn body. A pinion 12 v is secured to the projecting end of the paddle shaft by the pin 13 and is provided with a peripheral flange 14, which works against the inner face of the stationary gear Q, as shown in Figs. 1 and 2. The flange 14 holds the inner end of the shaft in its socket or bearing 11 and thereby prevents any endwise displacement of the shaft or paddle during the churning operation. A packing ring 15 receives one end of the shaft where it pierces the churn body and prevents any of the contents of the churn from leaking out. To remove the shaft 10 for any reason, it is first necessary to remove the pin 13 of the gear 12 and the pin 16 of the paddle.

It will be understood that as the churn is turned by means of the crank handle 5, the pinion 12 travels over the fixed gear 8 which causes the former to rotate and thereby rotate the paddle. The paddle is so geared that when the barrel is at an angle of approximately fifteen degrees to a vertical plane, the paddle extends in the same plane as the barrel, so as to offer the least possible obstruction to the removal of the contents or the cleaning of the churn body.

In the modification illustrated in Figs. 5 and 6, the flange 14 of pinion 12 is dispensed with and the gear or pinion arranged to travel around the teeth 17 of the gear 18.

From the foregoing description taken in connection with the drawings, it is thought that the construction and advantages of this invention will be readily understood without requiring a more extended explanation.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a churn, a supporting frame, a churn body in the form of a barrel or box mounted at its center in the frame, a paddle shaft extending through the center of the churn body eccentric to the central transverse axis thereof, a fixed gear on the frame, a paddle keyed to the shaft, paddle arms carried by the paddle shaft and extending in opposite directions, paddles at the outer ends of said arms, and a pinion on one end of the shaft arranged to travel over the fixed gear when the churn body is rotated, whereby the paddle shaft and paddle are rotated Within the churn body, with means for rotating the churn body by hand power, the paddle being so arranged on its shaft that the Wings or blades thereof are disosed in alinement and extend in a plane ith the churn body When at an angle of approximately fifteen degrees With a vertical plane.

2. In a churn, a supporting frame, a churn body in the form of a box or barrel revolubly mounted at its center in the frame, a fixed gear at the upper end of the frame, a paddle shaft arranged eccentric to the central transverse axis of the churn body With one end extending through the Wall thereof, a bearing on the inner Wall of the churn body for the inner end of the shaft, a paddle keyed to the shaft, a pinion on the projecting end of the shaft arranged to intermesh With or travel over the fixed gear as the churn body is rotated and a peripheral flange at the inner face of the pinion engaging the inner face of the fixed gear whereby the paddle shaft is held against endwise displacement When the churn is rotated.

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