CHURN.

SPECIFlGATEON forming part of Letters Patent No. 695,936, dated March 25, 1902.

Application filed July23,1901. Serial No. 69,431. (No model.)

To @ZZ whom it may concern:

Beit known that I, TRACY S. KITCHEN, a citizen of the United States, residing at Willard, in the county of Carterand State of Kentucky, have invented anew and useful Churn, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of rotary doubledasher churns and to provide a simple and comparatively inexpensive one adapted to utilize for churn-bodies receptacles of various sizes and capable of enabling the dashers to be readily removed and thoroughly cleaned after the operation of churning has been completed.

Another object of the invention is to provide a churn of this character capable of thoroughly and rapidly agitating the contents of the churn body and of quickly producing butter.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the-claims hereto appended.

In the drawings, Figure 1 is an elevation of a churn constructed inV accordance with this invention, the churn-body being removed to illustrate the dasher more clearly. Fig. 2 is a Vertical sectional view of the same, the churn-body being illustrated in dotted lines. Fig. 3 is an enlarged sectional view illustrating the manner of connecting the dashers with the operating mechanism. Figs. 4 and 5 are detail views of the dasher.

Like numerals of reference designate corresponding parts in all the iigu res of the drawings.

l designates a supporting-frame provided with a base 2, adapted to receive a churnbody and having vertical posts or standards Ll and 5 arranged in pairs at opposite sides of the base and rising therefrom. The .rear standards 5 are connected by oppositely-inclined braces 6, and both pairs of standards are connected at their upper portions by horizontal boards or pieces 7 and 8, arranged, respectively, at the top of the frame and Iat a point adjacent to the same. The frame is also provided at its sides with inclined braces 9,

the lower connecting piece or plate S and secured to the side edges of the same adjacent to the rear standards. The horizontal connecting pieces or plates are provided with extensions, and they have upper and lower bearings 10 and l1 at the outer ends of the same. The upper bearing 10 receives a vertical shaft 12,and the lower bearing receives a sleeve 13, arranged on the lower portion of the shaft, as clearly illustrated in Fig. 3 of the accompanying drawings. The shaft and the sleeve are provided at their upper ends with pinions 14 and 15, meshing with a gear-wheel 16. The pinions, which preferably consist of bevelgears, are arranged horizontally, and the gear-wheel 16, which is disposed vertically, is mounted on the inner end of a horizontal shaft 17 and is adapted to rotate the shaft and the sleeve in opposite directions. The horizontal shaft is journaled in suitable bearings of cross-pieces 1S and 19 and is provided at its rear end with a crank-handle 20, located at the back of the frame, as clearly shown in Fig. 2. The shaft is provided at the upper end of the sleeve with a shoulder or collar 21, forming a stop for the said sleeve and preventing the same from moving upward therefrom. The lower end of the sleeve is provided with a rectangular loop 22 and rests against a lower collar or sleeve 23, arranged within the loop at the top thereof, and the lower end of the shaft extendsinto an opening 24 of the bottom of 'the loop 22 and is provided with a socket 25 to receive the stem 26 of an inner dasher 27. The stem 26 of the inner dasher has its upper end reduced to fit into the socket of the shaft, as clearly illustrated in Fig. 3

of the accompanying drawings, and the reduced end 27 of the stem and the socket are preferably square in cross-section. The reduced end of the stem is also provided with an opening 28, adapted to receive'an arm 29 of a catch 30, mounted on the exterior of the lower portion of the shaft, as clearly shown in Fig. 3.

30 is arranged horizontally and extends through one side of the socket of the shaft and projects into the opening 28 of the stem of the dasher, whereby the latter is detachably connected with the shaft.

The stem 2G of the inner dasher 27 is proextending from the front of the platform to L The engaging arm 29 of the catch IOO vided at its lower end with a shoulder 3l, arranged to support a sleeve 32 of an outer dasher 33, which is'connected with the rotary sleeve 13 by the rectangular loop 22, whereby the inner and outer dashers will be reversely rotated. The sleeve or tubular stem 32 of the outer dasher is provided at its upper end with a pair oflugs 33,`which engage openings 341.- of the bottom of the rectangular loop 22, whereby the outer dasher is detachably interlocked with the same when the parts are assembled, as shown in Fig. 3. The catch 30 by engaging the reduced portion 27 of the shaft 26 retains the projecting lugs 33a in the openings34 of the bottom of the loop 22, and when it is disengaged from the reduced upper portion 27L the inner and outer dashers may be readily removed from the shaft and from the rotary sleeve. The tubular stem or sleeve 32 is provided with a longitudinal slot or opening 35, adapted to permit ready access to its interior, so that it may be thoroughly Washed and cleaned after the operation of churning has been completed.

The inner dasher consists of a blade having a slight twist, and the outer dasher 33 consists of a pair of blades connected with the lower end of the tubular stem 32 by a cross piece 36 and provided with partial twists. The tendency of the inner dasher is to force the liquid contents of the churn-body upward, and the outer dasher is designed to force the liquid downward or in the opposite direction, and by this operation the contents of the churn are rapidly and thoroughly agitated and butter is quickly produced.

The churn-body may consist of an ysuitable receptacle, and it may be ofany desired size which will bring the cover at a point between the tops of the dashers and the loop 22, and its cover is designed to be provided with a central opening for the stems of the dashers. When the crank-handle is turned, the inner and outer dashers will be rapidly rotated in opposite directions.

It will be seen that the churn is simple and comparatively inexpensive in construction, that it is adapted to be easily operated, and that after the operation of churning has been completed the dashers are readily removable and may be easily cleaned. It will also be apparent that the blades of the dashers have a slight twist, which will enable them to turn easily through the contents of the churnbody, and that this arrangement reduces the resistance to their rotation to a mnimu m and at the same time does not lessen the agitation of the contents of the churn. The churn requires a minimum amount of power to operate it and affords a maximum agitation of the contents of the churn-body and enables butter to be quickly produced.

l. The combination of a frame, a vertical shaft provided at its lower end with a socket, a rotary sleeve arranged on the shaft and having a loop at its lower end, an inner dasher havinga stem fittingin the socket of the shaft, a' catch mounted on the shaft and located within the loop and engaging the stem of the inner dasher, an outer dasher having a tubular stem arranged on and supported by the stem of the inner dasher and detachably interlocked at its upper end with the bottom of the loop and retained in such engagement by the said catch, and gearing for rotating the sleeve and the shaft, substantially as described.

2. The combination of a frame, a vertical shaft, a rotary sleeve mounted on the shaft and provided at its bottom with a loop, an outer dasher having a tubular stem provided with a lug interlocked with the bottom of the loop, an inner dasher having a stem extending through the tubular dasher-stem and engaging and supporting the outer dasher, a fastening device located within the loop and securing the stem of the inner dasher to the shaft and holding both dashers in position, and gearing for rotating the dashers, substantially as described.

3. The combination of a frame, a vertical shaft, a sleeve mounted on the vertical shaft and provided at its lower end with a loop, an outer dasher having a tubular stem interlocked with the loop and provided with spiral 1 blades spaced apart, an inner dasher arranged in the space between the said blades and provided with a spiral blade, said inner dasher engaging the outer dasher to hold the same in engagement with the loop, and a locking device located within the loop and securing the inner dasher to the shaft, substantially as described.

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

TRACY S. KITCHEN.
