CHURN.

SPECIFICATION forming part of Letters Patent No. 656,010, dated August 14,1900.

Application filed February 16,1900. * Serial Ko. 5,445. (Ko model.)

To all whom it 'may concern;

Be it known that I, Charles Waller Bowling, a citizen of the United States, and a resident of Fulton, in the county of Calla5 way and State of Missouri, have invented a new and useful Improvement in Churns, of which the following is a full, clear, and exact description. ..

The purpose of the invention is to provide io a churn-dash so constructed that it may be readily cleaned or turned either way with equally-satisfactory results and so that the dash will produce both agitation and aeration, which combined actions are very desirable. 15 The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying 20 drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section through a receptacle in which the churn-dash is repre25 sented in perspective and likewise illustrates a support for the driving mechanism of the churn-dash. Fig. 2 is an inside view of one section of the churn-dash. Fig. 3 is an outer face view of the churn-dash. Fig. 4 is a ver30 tical section through the bottom portion of the churn-dash, the two sections being brought together; and Fig. 5 is a bottom plan view of the improved dash.

The churn-dash A is tubular aud is in two 35 longitudinal sections 10 and 11, each of which sections is transversely semicircular, and the object of constructing the dash in two sections is to enable the parts to be readily cleaned. The dash may be made of any suit40 able material, and preferably in the upper portion of each section 10 and 11 of the dash a block 12 is secured in any suitable or approved manner, and in each block a longitudinal groove 13 is produced. The grooves 45 of the two sections of the dash register when the sections are brought together and are adapted to receive and clamp the upper portion of a spindle 13^a, which extends down into the dash any desired distance. An opening 50 14 is produced in each section of the dash below the block 12, secured therein, and these openings are adapted to admit air into the in terior of the dash. Each section of the dash is provided with a bottom 15, and each bottom portion 15 of the dash has a downwardly- 55 extending flange 16, as is shown in Fig. 4. ; These flanges serve to agitate, the milk as the dash is revolved or turned from side to side. A lower opening 17 is made in each section 10 'and 11 of the dash just above the bottom 15, 60 as is clearly shown in Figs. 2 and 4, and a wing or blade 18 is horizontally secured to each section 10 aud 11 of the dash just above the lower opening 17. These wings 18 are of any suitable shape; but usually they are 65 wider at their outer than at their inner ends. Each wing 18 is provided with two horizontal ribs 19, secured to its under face and extending downwardly therefrom, and the inner ends of the ribs 19 connect with The body of 70 the dash, one at each side of the openings 17 in the dash.

The construction of the lower portion of the dash is such that when the dash is turned it will create a suction at the bottom of the 75 dash, and therefore will produce a partial vacuum in the body portion of the dash and cause the air to rush in through the openings 14 and reach the butter and the milk, since the openings 14 are above the surface of the 80 milk.

The sections of the dash are usually held together by a band 20, which encircles the sections at or near the bottom of the dash and through the medium of a second split 85 band 21, located at the top portion of the dash, the ends of the split band being tightly drawn together through the medium of a setscrew 22 or a like device.

In order to promote the agitation of the 90 milk in the receptacle 23, in which the improved dash may be introduced, a plate or blade 24 is located, within the receptacle a suitable distance from one side and parallel with the body of the dash, and this plate dr 95 blade 24 is usually held in position by means of a bracket 24^a of any desired, construction and capable of being hooked over the upper edge of the receptacle 23, as illustrated in Fig. 1. The receptacle 23 is usually made to 100 rest upon a base 25, upon which base a frame 26 is constructed, and at the upper portion of the frame 26 the driving mechanism for the spindle 13^a is located, which spindle, as

656,010 lias been described, is clamped to the dash, so that when the spindle is turned the dash A is also turned. This driving mechanism may be of any suitable construction. As rep5 resented, it consists of a wheel 29, mounted to turn in suitable bearings and provided with a handle 30. A rope 31 is passed around the periphery of the wheel, and this rope is twisted around a spool 32, secured to the upio per end of the spindle 13^a, and the rope 31 is likewise made to pass in engagement with guide-rollers 33 at each side of the spool 32, as shown in Fig. 1.

When the dash is in operation, which will 15 cause a partial vacuum to be formed at the bottom portion of the body of the dash, the air rushing in at the upper portion of the body of the dash through the openings 14 passes downward and causes the milk or 20 cream to be aerated while agitation is in progress, thereby combining two forces, either of which will cause the butter to be separated from the cream; but when these two forces are combined a much better result is obtained. 25 While the wings 18 are preferably at right angles to the body of the dash, the wings may be inclined upwardly in direction of their free or outer ends without departing from the spirit of the invention.
