CHURN.

SPECIFICATION forming part of Letters Patent No. 595,627, dated December 14, 1897. Application filed May 26, 1897. Berial No. 638,285. (No model.)

To all whom it may concern:

Be it known that I, ASA HAZELTON, a citizen of the United States, residing at Middletown, in the county of Montgomery and State of Missouri, have invented a new and useful Churn, of which the following is a specification.

My invention relates to churns, and has for its object to provide a simple and efficient construction and arrangement of parts whereby the tempering of the contents of the churnreceptacle is facilitated to avoid the introd action of tempering liquid into said contents.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a churn constructed in accordance with my invention, the receptacle being shown in section to disclose the dasher and tempering-can. Fig. 2 is a detail sectional view of the dasher, showing the tempering can mounted therein in operative position and showing in dotted lines the position of the can when it is desired to remove the same from the dasher.

Similar numerals of reference indicate corresponding parts in both figures of the drawings.

1 designates a frame in vertically-alined bearings, in which is mounted the dasherstaif 2, to which is fixed a pinion 3 for receiving motion from a driving-gear 4:, said driving-gear being carried by a shaft 5, having a crank-arm 6.

The dasher is of hollow or open construction and preferably consists of upper and lower cross-heads 7 and 8, connected by spaced blades 9, the center of the space inclosed by the dasher being entirely open, and hence adapted for the reception of a tempering-can 10, which is provided at its lower end with a pin 11 to engage a socket in the lower cross-head of the dasher, and is provided at its upper end with spaced pins 12 for engagement with suitable sockets in the upper crossbar of the dasher, said upper pins being longer than the lower pin to provide for the elevation of the tempering-can to the position shown in dotted lines in Fig. 2, in order to the water used is either hot or cold, according to the requirements.

The receptacle 13, in which the dasher operates, is provided with a removable halved or sectional lid 14, having a central opening through which the dasher-staff extends, and the Walls of the receptacle are provided with breaker-strips 15.

From the above description it will be seen that the tempering-can, which is preferably of cylindrical construction and is provided in its top with a filling-opening fitted with a screw stopper or cap 16, is arranged within the space bounded by the paths of the dasherblades and in axial alinement with a dasher staff or concentric with the dasher, whereby the inertia thereof or the resistance which it offers to the rotary motion of the dasher is practically zero,'and hence does not materially increase the difficulty of operation. On the other hand, the arrangement of the tempering-can at the center of the dasher exposes it to contact with all of the contents of the churn-receptacle, for the reason that said contents, as they are thrown inwardly by contact-with the breaker-strips or are drawn inwardly at the bottom of the churn by the operation of the dasher-blades, come into contact with the surface of the can.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a churn, the combination with a'dasher having an open center and a surrounding series of blades supported by upper and lower spaced cross-heads, and means for operating said dasher, of a tempering-can of less length than the interval between the cross-heads, arranged within the space surrounded by the blades and between the cross heads, and means for detachably securing the can to the roe dasher, said means consisting of interlocking pins and sockets, the pins at the upper and lower ends of the can being of difierent lengths, substantially as specified.

2. In a churn, the combination of a dasher and operating mechanism therefor, said dasher having upper and lower cross-heads and connecting-blades, of a tempering-can of less length than the interval between the crossheads arranged concentric with the dasher in the space inclosed by the paths of the blades, and provided at its upper and lower extremities with pins of unequal lengths fitting in sockets formed in the facing sides of said cross-heads and adapted to be disengaged by axially moving the can, substantially as specified.

3. In a churn, the combination with a supporting-frame, and a churn-receptacle provided with breaker-strips, of a dasher having its staif mounted in bearings on said frame, j

operating mechanism for the dasher-staif, the, dasher comprising upper and lower armed cross-heads connected by spaced blades arranged in a series surrounding the axis of the dasher, and said upper and lower cross-heads being provided respectively with sockets, and a tempering-can of less length than the interval between the cross-heads arranged axially in the dasher, Within the space inclosed by the paths of the blades, and provided at its extremities with pins to engage said sockets in the cross-heads, duplicate 'pins being arranged at one end of the can to cause rotation of the can with the dasher, and the pins at the upper and lower ends being of different lengths to provide for moving the can axially to unseat the pin at one end, substantially as specified.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

ASA HAZELTON.
