SPECIPiCATION forming part of Letters Patent No. 356,625, dated January 25, 1887.

Application filed February 9,1886. Serial No. 191,297. (No model.)

To aZZ whom it may concern.-

Beitknown that 1, CHARLES Gnnrsrornna DAYIS, of Mercer, in the county of Union and State of South Carolina, have invented certain new and useful Improvements in Chums; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in vibrating churns; and it consists in the combination of a suitable base, astandard mounted thereon and having a suitable hearing attached to its upper end, an operatingshaft with a ily-whcel at one end and a crank at the other, a slotted reciprocating carriage or frame which moves horizontally in suitable guides, and the straps connected to opposite ends of the carriage and the dasher, as will be more fully described hereinafter.

The object of my invention is to produce a vibrating churn in which the carriage is moved back and forth by means of a crank, which is of such a length that the carriage is allowed to come to a dead stop for an instant before it reverses its movement, and thus cause the dasher to turn in the opposite direction.

Figure l is a front elevation of a churn mechanism embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a plan "View: A. represents a suitable base, upon which the mechanism is mounted and upon which the churn is placed. This base may be provided with suitable rollers, so that the machine can be moved freely around from place to place whenever so desired. Mounted upon this base A is the vertical support B, which is suitably braced in position and which has the ears C upon opposite corners of its upper end for the purpose of holding the standard D in avertical position. The standard Dis provided with a slot, so that it can be adjusted vertically at will, and through which the clainpingbolt E is passed.

Rigidly secured to the upper end of the standard is a suitable bearing-frame, F, through which the operating crank-shalt G passes. On the outer end of this shaft G is secured a flywheel, which is provided with a handle, by

means of which the other parts of the machine are operated. V The end of the crank passes into or through the slot H in the carriage I, which moves horizontally in suitable guides, J. These guides consist of flat bars having their ends bent at an. angle and suitable recesses made in their ends so as to catch over opposite edges of the carriage. This carriage has the slot made through its center, and has its two ends turned at an angle and. projecting outward toward the dasher. A single operating strap or cord, L, is used, and which is connected to opposite ends of the carriage, and which strap is made to pass around the handle of the dasher, as shown. The strap is connected to one end of the carriage by means of an adjustable hook, N, and at the other end of the carriage the straps are fastened bybeing passed through holes and tied, or in any other way that may be preferred.

As the crankshaft is made to revolve the carriage moves horizontally, first in one direction and then in the other. Just as the carriage reaches the end of its stroke, and before the reverse motion takes place, it is brought to a momentary halt in its movement, so as to allow the dasher to stop just before the reverse movement takes place. 'When the carriageis moved in one direction, the movements of the straps around the handle of the dasher cause the dasher to revolve first in one direction and then in the other.

The handle of the dasher is held in suitable guides upon the frame, and to the upper end of the handle of the dasher is attached a fan, a, for the purpose of fanning the operator, and to the handle of the dasher, just above the top of the churn, may be connected a leather or brush, Z), of any kind, to keep the dies away.

' Placed loosely upon the handle of the dasher is a perforated float, P, which floats upon the top of the cream, and which serves both to prevent the splashing of the cream through the lid of the churn and to show when the but ter is formed. The particles of butter rise through the perforations in the float, and thus make themselves visible more readily and quickly than they would if no indicator of this kind were used. This float also helps to gather the butter by causing the particles to adhere together asthey rise upward.

ICO

The dasher Q is provided with two prongs, each one of "which is beveledupon its inner face and made rounding upon its outer face. The flat inner surfacethrows the cream toward the center of the churn, while the rounding of the outer surface throws it outward against the sides of the churn.

The rapid rotary motions, first in one direction and then in the other, not only agitate the cream, but cause all air to pass down into and through the cream in such a manner as to assist in breaking the globules in which the butter is held.

I aware that endwise-moving carriages having operating-straps connected thereto, have heretofore been used, and these I disclaim. My invention differs from these in driving the carriage by means of a crank instead of by \Vi tnesses:
