Specification of Letters Patent.

Patented July 5, 1910.

Application filed March 5, 1910. Serial No. 547,549.

To all whom it may concern:

Be ift known that I, LOUIS HornR, a subect o residing at N. S. Pittsburg, 1n the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to churns designed for the manufacture of butter, ice cream, and as a mixer or merger for ingredients.

The object of my invention is to provide a churn with a novel dasher or agitator that will thoroughly commingle and agitate the contents of the churn.

I attain the above object by a simple, inexpensive and durable churn adapted to be manually operated and constructed upon a small scale for household purposes, but it is in this connection that I do not care to limit my invention, as the churn may be made upon a very large scale and operated by a motor or other source of power.

y invention will be hereinafter considered in detail and then claimed, and reference will now be had to the drawing forming a part of this specification, wherein there is illustrated a preferred embodiment of the invention, but it is to be understood that the structural elements thereof can be changed and modified without departing from the scope of the invention.

In the drawings: Figure 1 is a side elevation of the churn. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a front elevation of the churn. Fig. 4 is a plan of the same. Fig. 5 is a horizontal sectional view of the churn. view of a detached bearing. Fig. is a similar view of a detached locking lever. Fig. 8 is an enlarged detail view of a de tached shaft, and Fig. 9 is a perspective view of a detached agitator or dasher.

In the, accompanying drawings the reference numeral 1 denotes a receptacle preferably made of one piece of sheet metal having the vertical edges thereof soldered, brazed, or otherwise connected to form a rectangular structure. Secured in the bottom of this structure is a bottom plate 2 having depending flanges 3 adapted to be soldered or otherwise connected to the inner sides of the walls of the receptacle.

4 denotes a lid or cover adapted to fit upon the upper edges of said receptacle, said lid Fig. 6 is a pers ective or cover having a depending flange 5 extending into the upper end of the receptacle, and furthermore, a handle 6 whereby the lid or cover can be easily handled.

7 denotes suitable handles secured to the outer sides of the receptacle intermediate the ends thereof whereby the receptacle can be easily moved and carried.

8 denotes a shaft rectangular in cross secfor a greater part of its length, one end of the shaft being cylindrical, as at 9, and

threaded, as at 13. Detachably mounted upon the cylindrical portion 12 by a set screw 14 is a circular head 15, this head being provided with an opening sufliciently large to clear the rectangular portion 16 of the shaft whenmounting the head upon the cylindrical portion.

17 denotes a bearing having a slot 18 with one end thereof open, said bearing being riveted or otherwise secured, as at 19, to the inner side of the rear wall of th circular head 10 of the shaft 8. wall of the receptacle 1 is provided with an shaft is held in place by a locking lever 21 having an off-set portion 22 provided with a slot 23. The locking lever 21 is pivotally connected to the front wall of the receptacle,

the shaft while the off-set portion 22 provides clearance for the head 15. The outer end of the locking lever 21 is bent to form a handle 25 and is adapted to engage in a bracket 26 secured to the front wall of the receptacle 1, as at 27.

28 denotes a crank mounted upon the rectangular portion 16 of the shaft and retained thereon by a nut 29 said crank having a handle 30 whereby the shaft 8 can be easily rotated.

The dasher or agitator comprises cross arms 31 and 32, the inner sides of the arms 31 and the outer sides of the arms 32 being I through said shaft 8. 7 32-are: connected by transverse v w hi h trud-ing beyond theends of .15
