e rlie iena e i lr 3, 1 V Fi 77 9- TQflZZ/LOZLOW time onc rn:

Be it known thatl; TH M T1 914 SQNas citizen of the United States, residing t K g sher, i t e co n -1 K n fi he a d Sta Ok ah ma hav i v n d f tain new and useful Improvements in Churns; and I do declare the following to.

be a f deman ci a de 'ii tio of invent-ion, such as will enable others skilled in the art to which it appertains and u e th T i vent o re at t0 im rev me t in churns and particularly to workingbody churns.

One object of the invention is to, provide a churn of this character having an improved construction and arrangement of a resilient body supporting mechanism whereby the body of the churn may be rapidly vibrated or sprung upwardly and downwardly thus thoroughly agitating the cream and quickly turning the same into butter.

Another object is to provide means for regulating the tension of the resilient body supporting mechanism whereby the body may be operated more or less freely.

with these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l is a perspective view of my improved churn; Fig. 2 is a central vertical longitudinal section thereof; and Fig. 3 is a horizontal section taken on the line 33 of Fig. 2.

My improved churn comprises a body 1 which may be of any suitable size and shape but which is preferably in the form of a cylindrical can having in its upper end an opening 2 which is adapted to be closed by a tight fitting cover 3. Rigidly secured to one side of the body 1 is a vertically disposed sleeve or tube 4 which is adapted to receive the outer ends of the body supporting mechanism hereinafter described.

The body supporting mechanism herein referred to comprises upper and lower spring metal bars 5 and 6 the inner ends of which are bent at right-angles to form attaching members 7 which are adapted to be secured in any suitable-manner to any suitable support 8 said support being shown in the present instance as an upright post downwardly to the lower end of which are secured two diver g feet 9 are of suflicient length tojprovide "support for the cliu'rn whilebeing operated. The bars 5 anus are spaced apart to a distance corresponding to the length of the sleeve or tube4 on the body ofthe churn and the free end of the upper 5 is bent at right-angles to form a body attaching lug l0 whil the free end of the lower bar is bent upwardly toform a body tit-aching Th ugsio and "11" are engaged respectively ith e; upper and w r ends of the sleeve 4.

The learned l a s cu ely h ld in engagement with the ends of the sleeve 4 combined clamping and'tension bolt 12 which is engaged with alined apertures formed in the upper and lower bars 5 and 6 near their freeends as shown. The bolt 12 is provided on its lower end with a head 13 and on its threaded upper end with a tension nut 14 which is screwed downwardly on the bolt and into engagement with the upper bar 5. By arranging the bolt 12 as herein shown and described it will be seen that the lugs 10 and 11 will be securely held in operative engagement with the ends of the sleeve 4 and by providing the bolt with the clamping nut 14, it will be seen that the outer portions of the bars 5 and 6 may be more or less tightly connected or held more or less rigid thus regulating the tension or spring action of the bars and thereby permitting the body of the churn to be vibrated more or less freely.

By constructing and arranging the body supporting mechanism of the churn as herein shown and described, it will be seen that in order to operate'the latter, it is simply necessary to impart slight pressure to the top of the body or to the outer ends of the supporting bars whereby the body of the churn will be rapidly vibrated or swung up and down and thus agitating the cream and quickly-turning the same into butter.

In order to facilitate the churning action of the cream, the body of the churn has preferably arranged therein, a dasher or agitating mechanism which is herein shown and is preferably in the form of a wire coil 15 of suitable size, which is ofuniform dimensions throughout its entire length and conforms to the entire length of the inner cylindrical surface of the body 1, which coil extends from the bottom to the top of the body and through the coils of which the cream is forced by the reciprocating or vibratory movement of the churn body.

By constructing and arranging my improved churn as herein already shown, it will be seen that the same may be easily operated and a maximum movement obtained for the body of the churn from a minimum amount of effort or exertion on the part of the operator.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

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

Having thus described my invention what I claim is: V

1. A churn comprising a cylindrical body having thereon a sleeve extending the entire length of said body, a support, resilient bars having one end of each permanently secured to said support and having their opposite ends bent inwardly for detachable engagement with the opposite open ends of the sleeve, and a tension bolt passing through said resilient bars and provided with a nut whereby said bars are more or less rigidly connected and the tension thereof regulated.

2. A churn comprising a cylindrical body and a removable cover therefor, a dasher removably arranged therein and comprising a wire coil of uniform dimensions through- V nesses. V
