CHURN.

SPECIFICATION forming part of Letters Patent No. 446,470, dated February 17', 1891.

Serial No. 357,279. (No model.)

To @ZZ whomJ t may concern.:

Be it known that I, ALBERT C. RrcHAnDsoN, a citizen of the United States, residing at South Frankfort, in the county of Benzie and State of Michigan, have invented a new and useful Ohurn, of which the following is a specification.

The invention relates to improvements in churns. l

ro The object of the present invention Ais to provide a simple and inexpensive churn capable of readily converting the lacteal Huid into butter, and of delivering the same upon a suitable plate for convenient removal.

rlhe invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

2o In the drawings, Figure l is a perspective view of a churn embodying the invention. Fig. 2 is a central vertical sectional view. Fig. 3 is a similar view taken at right angle to Fig. 2.

2 5 Referring to the accompanying drawings, l designates the body of a churn, preferably rectangular in construction7 and mounted upon diagonally-extending legs 2, and having two of its sides provided with panes of glass 3o 3 to permit the interior of the churn to beinspected without necessitating the removal of the cover 4, and one of the other sides is provided with a thermometer the bulb of which is arranged so as to be in contact with 3 5 the lact-eal fluid to indicate the temperature thereof, to enable the operator to readily ascertain the proper time and condition of the lacteal fluid for churning.

Arranged centrallyin the body of the churn 4o and having its lower end stepped in the bottom thereof is a vertical shaft 6, provided with dashers 7, having blades 8, and these rotary dashers 7 act in conjunction with stationary flasher-blades S, mounted upon rods 0, arranged upon opposite sides of the churnbody, and having their lower ends seated in suitable sockets of the bottom, and their u pper ends arranged in perforations of the cover Il, and the said stationary blades are arranged 5o in the intervals between the rotary blades and above and below the latter, and it will readily be seen that this arrangement of dashers is capable of quickly converting Lacteal fluid into butter by a most thorough and complete agitation of said duid. The upper portion of the dasher shaft 6 is provided with a spiral groove lO, adapted to form a screw conveyor to carry the butter as it is formed upward and deposit the same upon a perforated plate l1', extending across the upper 6o part of the churn and provided with a central opening l2 to receive the conveyer portion of the dasher-shaft; and the edges of said plates are provided with flanges and form a receptacle or dish of that portion of the plate between the outer edges or iianges and the central opening l2. The upper end of shaft is provided with a pinion lf3, that meshes with a cog-wheel ll, mounted upon the top of the cover and provided with a suitable handle for 7o operating the churn. The upper end of the churn finds bearing in a central opening of the cover, and the pinion is arranged above the same and is partially housed in a casing l5.

The body of the churn is provided with a suitable bail L16, and the cover is secured to the body in any desirable manner, preferably by means which will enable it to be quickly removed when desired. 8o

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will be readily understood.

It will be readily seen that the rods 9 may 85 be turned so as to present the blades 8 at different angles with relation tothe rotary dashers 7 of the central shaft.

Il. In a churn, the combination of the body, 9o the dashershaft having its lower portion provided with a series of dasher-blades, means for operating the dasher-shaft and the ad justable dashers, comprising the rods oppo' sitely disposed and provided with blades arranged in the intervals formed by the blades of the dashenshaft, and having their lower ends journaled in the bottom of the body and having their upper ends journaled in the cover and projecting above the saine and roo adapted to be turned to adjust tl eblades with relation to the blades oi the dasior, substantially as described.

V2. In a churn, the combination of the body, the dasher-sliaft having' its lowerportion provided With a Series of daslier-blades and its upper portion provided with a spiral groove, means for operating the daslier-sliaft, the adjustable dashers comprising` the rods oppositely disposed and provided with blades arranged in the intervals formed by the blades of the dasher-sllaft, said rods having their loweil ends journaled in the bottoni of the blades ot' the said rods and provided with pert'orations, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ALBERT C. RICHARDSON.
