Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed May 13. 1907. Serial No. 373.396.

,revolved or rotated relative to suitable paddles received therein, said paddles being station'ary throughout a churning operation, and

the parts being assembled in a substantialv and desirable manner to facilitate operation.

The invention embodies particularly, pe

culiar 'and novel structural features which will be more fully described hereinafter and which will be iinally claimed.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details `of construction of the means for effecting the result, reference is to be had to the following description and j accompanying drawings, in which:

Figure 1 is a side elevation of a churn embodying the invention; Fig. 2 is a vertical longitudinal sectional view bringing out clearly the arrangement of the several parts of the mechanism, and Fig. 3 is atop plan view, the cover of the churn being removed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Speciiicallydescribing the invention, and

`referring to the drawing, the numeral 1 indicates a stand which may be of any suitable construction and which preferably comprises sup orting legs 2. `Attached substantially to t e top of the stand 1 are spaced pillow blocks 3 in which is journaled a horizontal shaft 4. A small pinion 5 is secured to one end of the shaft 4 and is in mesh with a gear 6 carried-by a shaft 7 journaled in any desired manner in the upper end portions of spaced supporting members 8 which project upwardly from one end of the stand 1 from an end of the latter. A crank handle 9 is attached to one end of the shaft 7 and is operated in order to turn the gear 6 and the shaft 4, connected therewith. The end of the shaft 4 o posite that carrying the pinion 5 has a beve gear 10 attached thereto and said bevel pinion is in mesh with a similar pinion 11, horizontally arranged and journaled upon a stem 12 which projects upwardly from the stand 1 near the gear 10. At the lower end of the stem 12 and surrounding the same is a cup 13 in which are received a suitable number of ball bearings, the lower hub portion of the gear 11 being received in the. cup 13 and being in contact with the ball bearings designated 14 located inside of the cup. In other words the gear 11 is supported on the ball bearings 14 and rotates freely in mesh with the gear 10.

The body 15 of the churn consists ofa suitable receptacle, and is also journaled'for rotation upon the stem 12. Said churn body is provided with a tubular extension 16 located centrally of the bottom thereof, the tubular portion of said extension being coincident with an opening at the center of the churn body 15. The under side of the churn body 15 is formed with downwardly extending projections or lugs 17 at oppositesides of the opening therein and said lugs enter depressions or recesses 18 in the upper side of the gear element 11 and an interlocking connection is thus established between the gear element 11 and the churn body, where'- bywhen the gear 11 is rotated the churn body will revolve therewith. The extension 16 ofthe churn body 15 terminates at its upper end in the plane of the upper end of the churn body so that the liquid which is to be operated upon may fill the churn nearly to the top thereof. The stem 12 projects some distance above the -extremity of the Vtubular extension 16 and received on the projecting portion of the stem is a collar 19.

Said collar 19 is provided with opposite horizontal threaded openings leading tol the vertical opening which receives the stem 12 and in said threaded openings are received the threaded members 20. The members 20 have the inner ends thereof adapted to engage with the stem 12 in order to positively attach the collar `19 thereto, and each of the members 2() is formed with an opening leading from its outer extremity and threaded so as to receive the threaded extremity of a lateral arm 21 projecting from the upperportion of a paddle 22; In other words the members 20 not only attach the collar 19 to 4the stem v12 but they also constitute supv paddles 22 may be vertically adjusted by vertical adjustment of the collar 19. Eac of the members 20 is formed at its outer end with a hub to admit of ready application of a wrench or similar tool for adjusting the member in the manner s ecified.

The suitable cover 23 1s provided for the receptacle of churn body 15 and said cover receives the upper portion of the churn body when the parts are in operative positions. The cover 23 is formed with a central opening through which the upper extremity of the stem 12 passes, said cover being thereby centered.

It is contemplated that the various shaft and gear elements of the churn shaft be mounted in ball bearings, if desired, in order to facilitate the free revolution of the parts, and increase the ease of operation of the machine.

The paddles 22, being constructed with an irregular or angular contour, have a peculiar function of breaking up ythe cream, and also tend to prevent the cream from riding up the wall of the churn body by reason of cen trifugal force.

I-Iaving thus described the invention what is claimed as new is 1. In churn operating mechanism of the class described, and in combination, a stand, a horizontal shaft j ournaled u on said stand, a pinion at one end of the sha t, an operating gear in mesh with said pinion, a bevel pinion at the opposite end of said shaft, a vertical stem projecting upwardly from the stand adjacent to said bevel pinion, a cup located at the lower end of said stem and surrounding the latter, ball bearings received in said cup, a horizontal bevel pinion journaled upon the stem and having'its lower hub portion resting upon the ball bearings aforesaid, a churn body having a centrally upwardly projecting tubular extension at its central portion and through which the stem above mentioned passes, whereby the churn body is supported for revolution on the stem, the bottom of the churn body being formed with an o ening coincident with the tubular area of t e extension aforesaid, lugs projecting from the bottom of the churn body on opposite sides of the opening therein, the top of the horizontal bevel pinion aforesaid being formed with recesses receiving the lugs and establishing a detachable interlocking connection between the churn body and said pinion, a collar applied to the upper end portion of the stem, paddles attached to said collar and about which the churn body is adapted to rotate, and a cover for the upper end of the churn body.

2. In churn operating mechanism of the class described, and in combination, a stand, a horizontal shaft journaled u on said stand, a pinion at one end of the sha t, an operating gear in mesh with said pinion, a bevel pinion at the opposite end of said shaft, a vertical stem projecting upwardly from the stand adjacent to said bevel pinion, a cup located at the lower end of said stem and surrounding the latter, ball bearings received in said cup, a horizontal bevel pinion journaled upon the stem and having its lower hub portion resting upon the ball bearings aforesaid, a churn body having a centrally ,upwardly projecting tubular extension at its central portion and through which the stem above mentioned passes, whereby ythe churn body is supported for revolution on the stem, the bottom of the churn body being formed with an opening coincident with the tubular area of the extension aforesaid, lugs projecting from the bottom of the churn body on opposite sides of the opening therein, the top of the horizontal bevel pinion aforesaid being formed with recesses receiving the lugs and establishing a detachable interlocking connection between the churn body and said pinion, the upper end portion of the stem projecting some distance above the up er extremity of the tubular extension, a co ar disposed upon and receiving the upper extremity of the stem, horizontally threaded members screwed into said collar and adapted to engage the stem to iix the position of the collar thereon, said threaded members being provided with internal threaded openings, paddles arranged in the churn body and having lateral arms at the upper ends thereof formed with threaded extremities received in the threaded openings of the threaded members applied to the collar, and a covervfor the churn body.

In testimony whereof I affix my signature in presence of two witnesses. Y ERIK A. COLLIN.
