/ OF BOSTON, MASSACHUSETTS.

'CHURN.

SPECIFICATION forming part of Letters Patent No. 281,906, dated July 24, 1883.

Application filed April 4, 1881. (No model.)

To all whom it may concern.-

Be it known that I, HENRY W. MERRITT, of Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improved Device for Ohurning, &c., of which the following is a specification.

My device relates to that class of instruments in which agitating devices are combined with and made to work in vessels containing fluid or semi-fluid substances, like cream, paste, egg, 85c.

In the drawings, Figure 1 is a vertical view of my invention, the lower part being shown partly in section. Fig. 2 is a plan of the same.

A vessel, A, is made of any suitable form and size, and is provided with ears B B, into which eccentric-headed bolts B B are fixed. These bolts B B pass through openings in the cross-bar D, and when turned, as shown at B,

- Fig. 2, serve to lock the cross-bar D in place.

This also serves to hold the cover D.

To the cross-bar D, I attach two uprights, E and E, which serve for bearings for the shaft M, and also to hold the cross-bar F, said cross-bar F being held in place by the screwnut H. An extension, F, of this cross-bar serves as a bearing for the upper end of the vertical shaft K, the lower end of said shaft working in a step-bearing, K.

K K are arms extending from the shaft K, and serve to connect it with the beaters K K the upper end of the boaters being steadied by arms is, which extendfrom a collar, k,which surrounds the quill p. The shaft K has upon its upper end a bevel-gear, L, which is driven by the gear M, shaft M, and crank M. The revolution of the shaft K causes the vertical beaters K to' revolve. The number and form of these beaters K may be varied at will.

P represents a disk-dasher, which is attached to a quill, P, on the shaft K. The upper end of this quill is provided with a pin, P and a pitman, P, the upper end of the pitman being connected by a crank-pin, 1 to the gear M.

From the above it may be seen that by turning the crank M the revolving beaters K K will be set in motion around the vertical axis of the device, while the disk-dasher P will be caused to move up and down in the direction of the vertical axis of the device. Thus the substance within the vessel A will be subject to two kinds of motion, one acting at right angles to the other, which must necessarily cause a thorough mixing and beating.

The upright revolving dashers K K are provided with openings, as shown in Fig. 1, so that they may, in revolving and acting with the centrally-located vertical moving dasher P, cause a more thorough and complete agita tion of the cream.

I claim The churn-body A, provided with ears B, in which headed bolts B are j ournaled, in combination with the cover D, having cross-bar D, which is providedwith openings at each end, and adapted to hold said cover in place by means of said bolts B, the uprights E E, connected by cross-bar F, having extension F, the shaft M, having handle M and journaled in said uprights, the shaft K, journaled in extension F, and step K, and having a sleeve, P, sliding thereon, gears L M, which drive said shaft K, and a pin, P pitman P", and wrist-pin P*, for conveying motion to said sleeve P, the dashers K connected to shaft K and receiving rotary motion therefrom, and the dasher P, attached to the end of sleeve P, and moving up and down within the rotary dashers, substantially as herein specified.

HENRY V. MERRITT.
