CHURN-MOTOR.

SPECIFICATION forming part of Letters Patent No. 248,243, dated October 11, 1881. Application filed July, 16, 1881. (No model.)

1 To all whom it may concern.-

Be it known that I, M. WEST, a citizenof the United States, residing at Houston, in the county of Chickasaw and State of Mississippi, have invented a new and valuable Improvement in Churn-Motors; and I do hereby de clare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my invention, and Fig. 2 is a view of the opposite side.

This invention has relation to revolx ing churns; and it consists in the construction and novel arrangement of the devices for operating the same, all as hereinafter shown and described.

In the annext d drawings, the letter A designates al'rame, which may be conveniently constructed by securing the uprights B to the sills O, and connecting said uprights by means of the ties D at their intermediate portions, and the cap-bars E at their upper ends.

' Through bearings a, on the uprights B, extend the journals of the shaft F, which is squared to fit the square bearings b of the churn-case G, through which it passes, and is provided with a pinion, H.

K representsthe driving-shaft, which isjournaled in bearings c at the middle portion of the frame below the bearin gs a. On this shaft is located the large toothed wheel L, which is designed to engage the pinion H of shaft F. This large gear-wheel is loose on the shaft, and is provided with a pawl, N, which is kept in engagement with the ratchet-wheel R by means of a spring, S. The ratchet-wheel R is rigidly connected to the shaft K, and by the side of the ratchet-wheel a drum, J, is also firmly secured to said shaft. On the drum Jis wound around the large toothed wheel.

the rope e, which passes thence over a pulley or block, g, which is fastened to the ceiling or other high point, as indicated in the drawings. To the end of the rope is secured a weight, W, which is designed to be sufficient to operate the parts under the force of gravitation. A crank-handle, V, connected to the end of the driving-shaft, serves to wind up the rope on the drum.

The churn-ease is designed to be of square or angular formation. and its opening is provided with threads for the engagement of a screw-top, T, so that there will be no leakage during the revolutions of the churn. t

The operation is as follows: Thechurn having been filled and the rope wound up on the drum, the ratchet will become positively engaged with the pawl, and will therefore, as the weight descends and the drum turns, carry This whee], although, on account of its large diameter, it moves comparatively slowly, turns the pinion H rapidly, and thereby effects the revolution of the churn, which is attached to the pinionshaft.

Having described this invention, what I claim, and desire to secure by Letters Patent, lS

In a churn-motor, the combination, with the churn-shaft F and its pinion H, of the drivingshaft K, the drum J, and ratchet-wheel R, rigidly attached thereto, the lurge toothed wheel L, loosely engaged with said shaft, pawl N, pulley'g, rope e, and weight W, substantially as specified,

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

MAROELLUS WEST.
