SPECIFICATION forming part of Letters Patent No. 429,566, dated June 3, 1890. Application filed August 16, 1889.: Serial No. 320,921. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT FULTON CoL- LINs, a citizen of the United States, and a resident of Manchester, in the county of Adams and State of Ohio, have invented certain new and useful Improvements in Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the inven tion, which will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to churns, and has for its object certain improvements in a mechanism for imparting a reciprocating revolving motion to the dasher. the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the mechanism. Fig. 2 is a central longitudinal sectional view of the same. Figs. 3 and 4 are detail views; and Fig. 5 is a detail view of the bottom piece of the rectangular frame, showing the slot therein and the hinged piece pivoted within said slot.

Like letters of reference denote corresponding parts in all the figures.

The letter A designates a frame having a circular base, mounted for convenience on casters and two upright standards. In the top of this frame is constructed a rectangular box, the bottom piece B of which is furnished with a slot D and hinged piece E. This'slot D, as will be seen more clearly by reference to Fig. 5 of the drawings, extends inwardly from the front of the bottom piece or partition, and then laterally, the end thereof which receives the dasher-staff being rounded, so as to conform to the shape of said staff, the'entire slot being approximately L-shaped. The top piece 0 of said box is also provided with a slot F, over which closes a perforated and socketed button G. The dasher-shaft H is provided with a groove I, bearing in the rounded end of the slot D, and has its upper end reduced at J, registering with the bearing formed by the slot F and socket g of the button G. The hinged piece E is mounted upon a transverse shaft in the lateral extension of the slot D, and has its free end fitting in the groove I of the dasher-staff, said free end being rounded to conform to the shape I attain this object by of thestaff. removable stem L, bearing a fan M, is adapted to be inserted through an aperture in the button Ginto a socket K, cut in the end of the dasher-shaft. Then this stem is thus applied, the fan will be kept in motion by the revolution of the dasher-shaft, and flies and other insects kept from congregating about the churn.

[The dasher is rotated by means of a cord N, which is passed several times around the shaft between the grooves I and J, and has its ends fastened one to each of the levers 0. These levers are fulcrurned on a rod P, inserted through the upwardly-projecting and trifurcated end Q of one of the upright standards. The top piece 0 is also trifurcated at the end joining this standard, and suitable ways for the operation of the levers O are thus provided. Each lever has a pair of branching sockets 0 p, in either of which suitable lever-handles may be inserted.

In operating the mechanism the dasher is placed in a churn and the churn set on the circular base. At the same time the grooves I and J of the dasher-shaft are placed in their respective bearings and the hinged piece E pressed down into engagement with the groove I, as previously explained. Of course, when it is desired to remove the staff, all that is necessary to be done is simply to force the hinged piece'E upward out of engagement with the groove 1, when the staff is free to be taken out of its bearings. sired to use the fan, the stem L is inserted through the aperture g into the socket K. The cord N is adjusted as heretofore shown and the levers O alternately operated in opposite directions, by means of which the dasher is revolved about twice around and back. If the lever-handles be inserted in the inner pair of sockets, they will describe an arc of a circle from points between a horizontal and a vertical line, and if inserted in the outer pair of sockets the motions will be right and left, or in an arc of a circle described between two obliquelines, so that they can be conveniently operated by a person either sitting or standing. The box may be closed when operating by means of the hinged door R, which is fastened by atnrn-button.

As before stated, the free end of the hinged If it is depiece E is rounded or recessed to conform to the shape of the staif, and this recess is of such depth or size as to allow the end of the piece to pass by the shoulder above the part I, as seen in Fig. 2, when said piece is raised or depressed.

As to the form of the dasher proper and of the churn-barrel with which it is to be used, I make no claim, and they therefore need not be particularly described.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The herein-described churn, consisting of the frame having the upwardly-extended trifurcated side piece, the levers having the branching sockets and f ulerumed in the trifurcated side piece, the cords connected to said levers and the dasher-shaft, the dasher having its shaft formed with a groove and its upper end reduced, the partition having an opening to receive the groove of the shaft, the fan fitting in said shaft, and the button in which the fan-shaft turns, all as shown and described.

2. In a churn, the combination of uprights, one of said uprights being provided with a trifurcated upper end, a top piece provided with a trifurcated end registering with the trifurcated end of the standard, and also provided with the central aperture, a transverse partition provided with an opening, a dasherover said opening, andprovided with a socketed under surface, in combination with a dasherstaff provided with a reduced and socketed upper end fitting within the socketed under surface of the turn-button, a stem passing through an aperture in said turn-button and seated within the socketed upper end of the dasher-staif, said stem carrying a fan, and mechanism for imparting rotary motion to the dasher-staif, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereunto aiiixed my signature in presence of two witnesses.

ROBERT FULTON COLLINS. Witnesses:

DAVID DUNBAR, JAMES W. BRADLEY.
