AR K j speqi fi ii fnea me t. Patented May 18,1915- Application filed December 8, 1913.; SeriaLNo. 805,207.

To all whom it mayconcern: a Beit known that I, TAYLOR J. SMITH, a

citizen of the United States, 9 residing at,

Union City, in the county of Campbell and State of Georgia, have invented certain new and useful Improvements in Gearing, of which the following is .a specification.

My invention relates to improvements in gearing especially adapted for use, with churns, the object of the invention being to provide an improved arrangement of'triple dasher shafts with an improved mounting therefor enabling the mechanism to-be readily placed within and removed from a suitable container, and which protects the working parts of the churn against possibility of contact with the cream, and thereby prevents injurious consequences to the cream as well as to the working parts.

' A further obj'ectis to provide improve ments of this character in which the upper.

ends of the dasher shafts and the gearing imparting motion thereto is confined within a housing located centrally of a plate, which latter is designed to cover a container and permit of ready removal when desired.

With these and other objects in view, the

invention consists in certain novel features of construction and combinations and arrangements of parts as 'will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings: Figure 1 is a view in vertical section illustrating my improvements. Fig. 2 is a top plan view. Fig. 3 is a fragmentary view in section on the line 38 of Fig. 1. Fig. 4: is a view in horizontal section on the line 41- 1 of Fig. 1. Fig. 5 is a view in section on the line 5-5 of Fig. 1. Fig. 6 is a perspective view of one of the dashers. I

1 represents a container which may be of any suitable material having at a point below its open upper end, an internal annular flange 2 with notches 3 formed therein.

1 represents a plate which is of general conical form and of a diameter to fit within the container 1, and rest upon the flange 2 V of the latter. A depending annular flange 5 is formed on plate 2 at a point removed from its outer edge, and this flange 5 projects into the receptacle within the flange 2, and is provided with lugs 6 which are adapted to be projected through the notches 3,

and when-the; plate. isiturned, securely lock the plate. in the container.

- The plate 4 is providedcentrally with a pocket, 7 'over which a removable casting 8 is secured by means of screws 9, which latter. extend through the lower end of the caste ing;.8, and arescrewed into the plate 4:. The casting, 8. and the pocket; 7 together consti-j tute a gear housing in which my improved 7 arrangement of gearing is inclosed.

Plate Q in the bottom of housing 7,, is

formed with integralbearings. 10 through which dasher shafts 11 project. The upper ends of these shafts 11,, which are reduced in diameter as shOWn at 12, project into bearings, 13, in enlargements 14 integral with castingfS, so that the-shafts have two hearing points at their' pp d one in plate 4, and the other the casting 8. I have illustrated, and: preferably employ three dasher shafts which at theirlower reduced ends are supportedto turn in bearings 15 "in a ring 16. This ring is held in position by nuts 17 onthe lower screwthreaded ends of the shafts 11 below the ring as indicated clearly in Fig. 1.

Each shaft 11 is provided with dashers 18 having central sleeves 19 secured to the dasher shafts in any desired manner and projecting at both ends beyond the shaft,

In the center of pocket 7, a short arbor 21 is secured and supports a gear 22 which meshes with pinions 23 on each of the dasher shafts 11, and transmits motion to all of the shafts to turn them simultaneously.

An integral beveled pinion 24 is formed on gear 22, and meshes with a beveled driving gear 25 secured on a horizontal shaft 26 projecting beyond the, casting 8 and having a crank arm 27 thereon to turn the same.

While my invention is not limited to any particular style of container, it is especially adapted for'use on earthenware jars or similar receptacles, and the construction of plate- 4 with its lugs 6 is especially adapted for interlocking in a container of this kind.

It will be noted that when the shaft 26 is turned, gear 25 will impart motion to pinion tion,

24: and gear 22 to drive all of the da'sher shafts 11 through the medium of the pinions 23, and cause the dashers to move rapidly through the cream and quickly churn the same into butter.

The shafts, as above stated, have two bearings at their upper ends, one in the plate 4, and the other in the casting 8 with the pinions 23 secured on these shafts between these two bearing points, so that the pinions are firmly held in mesh with the center gear 22 and a strong properly meshing gearing is had. Furthermore, all of the operating parts are safely housed within the housing formed by casting 8 and pocket 7 so that none of the cream can get into the gearing and no grease or dirt from the gearing can find its way into the cream. The device is therefore a perfectly sanitary one, and all of the operating parts are in a strong assemblage which may be readily placed in a container and thoroughly cleansed after the churning operation.

Various slight changes might be made in E the general form and arrangement of parts described without departing from my invenand hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A housing comprising a plate provided with a pocket in its upper face, and a superimposed member detachably secured thereto, an arbor projecting upwardly from the bottom of said pocket, a gear wheel rotatably mounted on said arbor and arranged within said pocket, said gear wheel being provided with an integral beveled pinion, a transverse shaft in said superimposed member, a beveled gear fixed to said shaft and meshing with said beveled pinion, alined bearings in said plate and super-imposed member respectively, a shaft mounted in said bearings, and a pinion on said shaft within said pocket and meshing with the first said gear, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
