CHURN.

SPECIFICATION forming part of Letters Patent No. 697,204, dated April 8, 1902.

Application filed June 15, 1901. Serial 1210. 64.715. (No model.)

To (0Z5 whom it ntay concern.-

Be it known that LJOHN GROENDYKE, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.

My invention relates to improvements in churns; and the main object of myinvention is the provision of a churn provided with an aerating means and also with an adj ustablyremovable auxiliary dasher device independent of the dasher carried by the main shaft.

Another object of myinvention is the pro vision of a churn which is quickly and easily taken apart for cleaning or assembling for use and one which is very useful and practical.

To attain the desired objects, the invention consists of achurn embodying novel features of construction and combination of parts, substantially as disclosed herein.

In the drawings, Figure 1 is a side elevation of the churn complete. Fig. 2 is a vertical section taken through the shaft. Fig. 3 is a perspective of the auxiliary dasher attachment.

Referring to the drawings, A designates a base or platform, which has secured thereto and arising therefrom the vertical standard or support B, which is provided with the cross-arm O and the forward right-angled bracket D. Journaled upon a shaft E at the rear near the top of the support is a crankwheel F,in whose groove is mounted the strap or band G, which is guided through the pulleys H, secured to the cross-arm, so as to fit in the groove J of the spool or shaft K. This spool or shaft is provided with the reduced upper end L and the reduced spindle M, each of which is journaled, respectively, in the alined recesses or bearings N in the outer ends of the bracket. By this construction the strap or band surrounds the spool and holds it closely in the bearings, and to remove the spool it is simply necessary to remove the strap from engagement with the crank-wheel.

Secured to the lower reduced end 0 of the spool is a vertical tube or sleeve P, which is provided with the perforations or openings Q, communicating with the outside air and the interior of the tube, the spouts D being connected to the outside of the tube around the openings, so as to cause a current of air to be directed into the tube as the same is revolved. Connected to and revoluble with the tube near its lower end is the plate R, having the downwardly-projecting rim or flange R, which forms an auxiliary support for the perforated dasher wings or plates S, whose upper sides-are connected to the under side of the plate Rand whose inner sides are connected to the-tube extending from the plate R to the end of the tube. The lower edges of these wings are slightly inclined from the tube upward.

Adapted to fit within the receptacle T are the series of expansion-rings U,Which are split rings and have adjustably mounted thereon the series of stationary auxiliary breakers V, which assist in the agitating and aerating of the cream as the tube is revolved.

From this description, taken in connection with the drawings, the operation and the numerous advantages of my improved aeratingchurn will be readily understood and fully appreciated, but the operation, briefly stated, is as follows: The churn is set in position, as shown in Fig. 1, and the cream is then placed in the receptacle. By revolving the crank- Wheel poweris transmitted to the spool, which in turn revolves the tube carrying the dasher. This motion in connection with the stationary breakers in the receptable cause the cream to be agitated, and by reason of the openings in the tube and the spouts leading thereto a current of air is forced through the tube and out at its lower end, where it passes upward through the contents of the receptacle, thoroughly aerating the same.

A great advantage of my churn from the ones in general use is the rotary movement of the dasher without the necessity of employ ing both of the gudgeons at the bottom of the receptacle, thus not allowing any sediment to collect in the bottom and a black substance to be precipitated so as to discolor the milk or butter.

It is evident that I provide an aeratingchurn which is the embodiment of simplicity, durability, and cheapness and one by reason.

of its easy and quick taking apart and assemblage renders itself thoroughly efficient and practical in use.

What I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described churn comprising a suitable body a standard rising therefrom, a pair of arms at right angles to the standard upon opposite sides, pulleys carried by said arms, a shaft mounted in the upper end of the standard, a grooved wheel journaled upon the shaft, a bracket upon the forward part of the standard provided with a pair of arms, alining recesses formed in the outerend of said arms, a spool having a reduced upper end, a grooved central portion and a reduced lower end mounted in said recesses, an endless cord or band passing around the wheel, through the pulleys and crossing over and around the grooved portion of the spool to transmit power to the spool and hold the same in the recesses, 'a churn-receptacle upon the base, and means carried by the spool for charging and supplying air to the contents of the receptacle. 4 v 2. A churn comprising a suitable base, a standard risingtherefrom, an arm secured to the rear side of said standard and having its ends extending upon each side and at right angles thereto, pulleys secured to the upper portion of said ends, a shaft journaled in the upper end and extending to the rear of the standard, a grooved crank-wheel mounted upon said shaft, an arm secured to the forward side of said standard and provided with a recess so as to form two parallel arms "the lower one of which is in line with the arm secured to the rear of the standard, vertical recesses or kerfs formed in the outer end of said arms so as to aline with each other, a spool provided with a reduced upper end and a reduced lower end having a collar therearound journaled, respectively, in the recesses of said arms, a grooved pulley formed integral with said spool, an endless belt passing around the wheel, through the pulleys, crossing over and then around the grooved pulley of the spool, to transmit power to the spool and hold it in the recesses, an aeratingtube carrying a dasher secured to the lower end of the spool below the collar, and a churnreceptacle mounted upon the base.

3. A churn comprising a suitable base, the standard rising therefrom,a bracket provided with two parallel alined arms provided with vertical slots in the ends thereof carried by the standard, a churn-receptacle mounted upon the base and having its center directly below the center of the inner edge of the slots,a spool having a terminal at one end and one near the other end fitting in said slots, a collar near the lower end, a hollow tube fitting upon the lower end and abutting against the collar, a series of air-directing spouts carried by the tube near the top thereof, a dasher carried upon the lower end of the tube which is above the bottom of the receptacle and surrounded by the same, a mechanism for revolving the tube and keeping the spool in the slots connected to the standard.

In testimony whereof I aflix my signature in presence of two witnesses.

hi JOHN GROENDYKE.
