CHURN.

SPECIFICATION forming part of Letters Patent No. 409,997, dated August 2'?, 1889.

(No model.)

To all whom it may concern:

Be it known that I, ELI MIOHAELS, a citizen of the United States, residing at Sweetsers, in the county of Grant and State of Indiana, have invented a new and useful Improvement in Ohurns, of which the following is a specification.,

This invention relates to churns of that class having a pair of dashers journaled on parallel vertical axes and rotating in opposite directions; and it consists in certain details of construction and arrangement of parts, all as hereinafter more fully pointed out.

In the accompanying drawings, Figure l is a side elevation. Fig. 2 is a central vertical section of one of the dasher-shafts. Fig. 3 is a horizontal section through the dashers; and Fig. 4 is an enlarged perspective detail of one of the dashers detached, showing my preferred form of wings. Fig. 5 is a central vertical section of one of the gear-wheels and its hub.

The same letters of reference are applied to corresponding parts throughout.

The letter J designates a jar, can, tub, barrel, or other receptacle within Vwhich the churning takes place.

My invention consists of the operative mechanism adapted to be removably anddetachably'connected with said jar, the latter being supplied by the operator, and hence of any desired size, shape, construction, and material.

T is a table having a downwardly-projecting fiange t, adapted to fit closely the mouth of the jar. Upon this table is mounted a frame-work comprising two side pieces F, connected near their upper ends by horizontal strips f. J ournaled in these strips and passing through holes in the table T are two vertical shafts S.

Upon the shafts are a pair of intermeshing gears G, having enlarged hubs II, and setscrews 7L pass through said hubs and are adapted to impinge against the shafts, thus adapting the gears to be set at any desired point upon the shafts.` Said hubs H are elongated and bear at their upper and lower ends against the inner faces of said strips f, whereby the shafts S are held from vertical dlsarrangement. The side pieces F are out away at proper points C, to permit the gears G to project therethrough, and on one of said pieces is pivoted a large gear-wheel W, turning in a vertical plane, meshing with one of the gears G, and having a handle fw by which it may be rotated. There are about three ti mes the number of teeth on the large gearwheel W as on the small gears G, whereby the latter make three revolutions to the formers one. Each shaft S carries within the jar two dashers standing at right angles to each other. Each dasher comprises a` horizontal arm D, passing through a rectangular transverse hole in the shaft, but'not fastened therein, and vertical wings ol, dovetailed upon each end of the arm D, with a pin cl passing through the junction to hold the parts in relative position. The shaftsS are set within the hubs H, so that the two upper arms D shall stand at right angles to each other and their wings d pass alternately between the shafts when the latter are rotated. The two lower arms being at right angles to the two upper ones, their wings will be just quartering thereto, and will also pass alternately between the shafts, one upper and the opposite lower wing passing therethrough simultaneously.

All the parts are preferably constructed `of woo`d, excepting the wheel W, which is of heavy iron-casting, in order to cause it to serve as a balance-wheel, and the set-screws h, which are obviously of metal. The Wings d are dovetailed into the ends of the arms D, preferably on the front faces thereof, and are held in place by wooden pins d. The dasherarms D, as above stated, pass loosely through rectangular transverse holes in the shafts, and the swelling of the wood, when the parts are wet, will hold them in position. When withdrawn from the jar and dried, the Varms may be slid laterally in the shafts and thoroughly cleaned, after which they may be set at any desired position, and the wetting afterward received will lock them there. The jar being filled or partially filled with cream, the wheel IV is revolved by its crank, resulting in the rapid rotation of the dashers in two horizontal planes. The body of cream in the jar will be set in motion in two verti- ICO cal columns, of which the shafts S are the axes, and these columns will intersect between the shafts, resulting in the violent dashing and thorough and rapid churning of the cream.

It will be obvious t-hat the churn mechanism proper may be removed from one jar and placed in another, larger or smaller, and that it may be manufactured and sold without the jar, which can easily be furnished by the user, thus lessening the selling price of the device, resulting in an increased market for it.

My preferred form of wing d, as illustrated in Fig. 4, comprises oneor morevertical members, preferably dovetailed into the front face of the horizontal arm D in its direction of rotation, and retained in position therein by wooden pins d', as above described. If the wings d are long, I may provide two horizontal arms D-*one at the upper and the other at the lower end thereofto afford a strong support therefor, both of said arms being mounted loosely in transverse slots in the vertical shaft S, and adapted to slide therein, as above described.

Each wing d is beveled on its front face, so

as to taper from its outer edge o to its inner edge t', asvclearly seen in the drawings. By

and thrown against the broad outer edge of the wing adjacent to it, and this Will result in a centripetal action exerted on the cream being churned, in contradistinction to the centrifugal force simultaneously generated by the rotation of the dasher entire.

It Will be obvious that a dasher so constructed would effect a more thorough and complete churning of the cream in a given Eme than the plain dashers now on the man I claim as the salient' points of my invention- The shaft S, the two arms D, passing through transverse holes therein at right angles thereto and to each other, vertical Wings el, dovetailed in the ends of said arms at right angles thereto, and Wooden pins d', for holding them in place, in combination with a second shaft S, having similar arms and Wings and standing parallel with said first shaft, the opposite arms being set quartering to each other, a pair of intermeshing gears keyed to said shafts, and a hand-wheel for imparting rotary motion thereto, as set forth.

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

RICHARD BEEsoR, JAMES MORE.
