CHURN.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed September 25, 1920. Serial No. 412,686.

To all whom it may concern:

Be it known that I, WILLIAM T. ROBERTS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Churns, of which the following is a specification.

This invention relates to a churn and has for .its primary object the construction of a churn that an ordinary Mason jar may be used as a receptacle.

An object of the invention is the novel manner of constructing the agitator so that the same may be readily inserted and withdrawn from the Mason jar and which may be readily attached thereto.

A feature of the invention is the novel manner of constructing and arranging the paddles so as to accomplish the greatest agitation of the liquid without interfering with the arranging of the agitator in place.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein: I

Figure 1 is a sectional view of my invention.

Fig. 2 is an enlarged side elevation of the bottom portion of the agitator showing the paddles in position to be forced from the ar.

Fig. 3 is a horizontal sectional view.

Fig. 4: is a detailed perspective view of one of the agitator paddles.

Again referring to the drawing illustrating one construction of my invention the numeral 1 designates a receptacle, which may be the ordinary Mason jar. Resting upon the neck of the jar is a disk 2 clamped into place by the rim 3 that has screw threaded engagement with the jar. The disk is provided with a hole 4 slidably receiving the rod 5 of the agitator 6. To the upper end of the rod is connected a handle 7 while the lower end is threaded. Mounted on the threaded end is an ordinary nut 8 and a thumb nut 9 for a purpose hereinafter described. The numerals 10 and 11 designate a pair of paddles, hereinafter to be known as the lower paddle and the upper paddle. The lower paddle is provided with flanges 12 engaging the nut 8 and has its longitudinal edges curved as indicated at 13 so that the projections 14 on paddle 11 may readily ride over the surface of the lower paddle so that the paddles may assume a parallel position and then tilted as shown 1n Fig. 2 so as to be readily removed from the jar. A coil spring 15 is arranged between the nut 9 to the paddles for yieldably holding the paddles in operative position while at the same time allowing them to be yieldably forced to position illustrated in Fig. 2.

It will be noted that projections 14; are so arranged as to hold the paddles against accidental dislocation when they are extended at right angles to each other which is their operative position. To complete the invention I provide a gasket 16.

From the foregoing description taken in connection with the accompanying drawing it will be apparent that I provide a churn that is simple in its operation and constructed of very few parts. The novel manner of constructing and associating the paddles enables the maximum amount of agitation to be accomplished without interfering with the ready insertion or removal of the agitator from the ordinary Mason jar to which it is attached.

The churn is absolutely sanitary owing to the construction and association of the parts as ready access may be had to all the parts for cleaning same.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. A churn comprising in combination a jar, a cap therefor provided with a centrally located hole, and an agitator consisting of a rod slidably mounted in said hole, paddles supported on the rod for swinging movement, a spring holding the paddles associated and capable of allowing the paddles to be forced into angular position relative to the rod so as to facilitate the passage of the agitator into and out of the jar, and projections on one paddle co-acting with the other paddle and the spring to hold the paddles in their operative position.-.

2. A churn comprising in combination a jar, a disk resting on the neck of the jar, a rim having screw threaded engagement with the jar for clamping the disk in place, and

an agitator consisting of a rod slidably supported by the disk, a handle connected to the upper end of the rod, a pair of paddles swingingly supported by the lower end of the rod a spring pressing the paddles into engagement with each other, and projections on one paddle cooperating with the other paddle to hold the paddles in operative position against accidental displacement.

3. A churn comprising in combination a jar, a disk resting on the neck of the jar, a rim having screw threaded engagement with the jar for clamping the disk in place and an agitator consisting of a rod slidably supported by the disk, a handle connected to the upper end of the rod, a pair of paddles swingingly supported by the lower end of the rod, a spring pressing the paddles into engagement with each other, and projections on one paddle cooperating with the other paddle to hold the paddles in operative position against accidental displace ment, the connection of the paddles with the rod and their co-action with the spring being such as to allow the angular position of the paddles with relation to the rod to be changed to facilitate the insertion of the agitator into and the removal from the jar.

In testimony whereof I afiix my signature.

WILLIAM T. ROBERTS.
