IION OF NEW YORK OF'IBINGHAMTON, NEW YORK, A. CORPORA- CHURN Application filed January 21, 1929. Serial 110. 884,085.

My invention relates to churns, more particularly to churns which are adapted for attachment to household washing machines rovided with oscillatory driving posts, and

as for its object the provision of apparatus of-the character designated which shall be simple of construction and operation, readily cleaned, and which shall be adapted for use with washing machines having various sizes of driving post heads.

A further object of my invention is to provide a churn for use with household washing machines having oscillatory driving osts a'nd wherein thetorsional strain on the c urn 16 and on the driving post is reduced to a minimum. 1 v A still further object of my invention is to provide, in a churn adapted for use with a washing machine having an oscillatory 0 driving post, an interchangeable coupling member for drivin the churn whereby the churn may be readily adapted for use with -various makes of washing machines:

' A still further objectof my invention is to provide an oscillatory churn with an improved removable dash which shall be effective to provide'thorough agitation for the cream, when the churn is in operation.

Variouskindsof churns have heretofore been providedfor use with household washing machines. These churns may be divided into two general classes, the first wherein the cream container is made stationary and means are provided for attaching a dash element to' the oscillatory shaft to agitate the cream, and the other wherein the cream container is made movable with the oscillatory shaft and is provided with vanes secured to the body of the container for imparting agitation .to the cream at the start and stop of the oscillatory movement of the container.

' It is to this latter class of churns that my invention relates. While this class of churns has ven eminent satisfaction in use, diiliculties ave been encountered in their operation.

due to excessive torsional strain upon the connection between the vessel and the driving postand also due to the fact that the integral dash elements render the cream container more or less difiicultto clean. It is furthermore ver desirable in devices ofthis kind to provi e a churn which may be readily adapted for use with different makes of washing machines and thus avoid the necessity of carryin a separate line of churns for each make 0 washing machines with which they are to be associated.

All'of these and other difii'culties are overcome by apparatus made in accordance with my invention and illustrated in the accompanying drawings, wherein Fig. 1 is a vertical sectionalview of the proved churn comprises a cream container 10 provided with a suitable cover 11 and having a bottom 12 through which extends upwardly a hollow sleeve 13 through which motion is transmitted to the container. The container is preferably made of metal and the hbllo'w sleeve 13 is designed to better withstand torsional strain by providing an 11 ward bulge to the bottom 12 and by provi 'ng a conical brace 14 which is secured to the bottom 12 and is provided with a central aperture havin its sides secured to the post 13 in any suitable manner, for example, by welding. The cover llis provided with a sight glass 15 through which the churning operation may be seen without stopping the vessel.

The hollow post 13 is provided with a cover 16 having an angular head 17 and having depending marginal In S 18. The cover 16 fits snugly within the ho low post 13 and issecured thereto by. soldering or welding so as to make a smooth, fluid tight joint. Centrally on the lower side'of the cover 16 is a squared lug 21 provided with a tapped hole 22 in which fits a screw 23.

to the drawings for a bet mg machines. The size and shape of the heads 31 are different in the different makes of washin machines and it will be apparent that coupling members 24 may be in different sizes and shapes to accommodate the different size and shapes of driving post heads and a I churn be adapted for association with any one of the several makes by simply attaching to "the cover 16 the appropriate size coupling member 24.

' Fitting over the'squared head 17 of the coupling member is a transverse dash supportmgmember 36 having a central opening 37 shaped to fit 'the head 17. For convenience of manufacture, the member 36 is preferably made up of two pieces of strap material secured together and carrying between their outer ends dash elements 38 and 39. The dash elements 38' and 39 extend upwardly to the maximum level of the cream so as to insure agitation thereof and are positioned outwardly near the wall of the container. Extending across the to of the dash elements 38 and 39 and secured t ereto by welding is a channelshapeddashelement 40. The function of i the dash element 40 is todefiect the cream downwardlyat the beginning and ending of the oscillatory movement when it is being forced upwards along the elements 38 and 39. It will be seen that as the driving post 32 oscillates, the vessel 10 and dash elements 38 and 39 oscillate with it. It will furthermore be seen that each time as the oscillatory movement starts and stops, agitation is provided for the cream in the container 10 by its impact with the dash elements 38 and 39 and is deflected downwardly by the dash element 40. These dash elements being secured to the head 17 through the member 36 the major portion of the torsional strain is'transmitted. directly to the driving post 32 through the cap 16 and coupling member 24 and a minimum of strain is imposed on thesleeve 13 as is the case where the dash is integrally secured to the walls of the vessel. It will furthermore be seen that, as the oscillatory movement starts and'stops, less torsional strain is imposed on the hollow sleeve 13 than would be imposed thereon with dash elements integralwith the container.

From the foregoingdescription, the operation of my improved apparatus will be readily understood. The dash being fitted on the head 17 and the vessel 10 being filled with cream to be churned, the hollow sleeve 13 is lowered over the driving post 32 with the head 31 fitting in the cup shaped coupling member 24. Power is applied to the driving post 32 to impart thereto an oscillatory motion, as is well understood, whereupon the vessel 10 and dash elements 38, 39 and 40 oscillate' in unison with the driving post 32. Due to the inertia of the cream within the vessel 10, it is subjected to violent agitation at each beginning and ending of the oscillatory movement so that butter is quickly obtained from the cream. When the churning operation has been completed, the contents may be removed, the dash removed from the head 17 and the interior of the churn be readily cleaned. By providing suitable coupling elements 24, the churn may be adapted for use with various makes of washing machines having different sized driving post heads.

From the foregoing it will be apparent that I have devised an improved churn attachment for washing machines which is simple of design and easy of manufacture and which reduces torsional strains on the driving mechanism to a minimum.

While I have shown my inventlon in but one form, it Will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire therefore that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
