UNTTED STnTns aTnNT WILLIAM Josnrn rmt-inn, or eRovn'roN, TEXAS- CHURNPQM/ERl SPECIFICATION forming part of Letters Patent No. 452,846, dated May 26, 1891.

Application filed August 2, 1890. Serial No. 360,773. (No model.)

T0 @ZZ whom t may concern.:

Be it known that I, WILLIAM Josnrn Mn- GEE, a citizen of the United States, residing at Groveton, in the county of Trinity and State of Texas, have invented a new and useful Churn-Power, of which the following is a specification.

This invention has relation to improvements in churn-motors, and has special reference to the means for connecting the pitman with the churn-dasher and to means for guiding said pitman and dasher at their joint.

lVith the above objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claim.

Referring to the drawings, Figure l isa perspective of a churn-motor constructed in accordance with my invention. Fig. 2 is a detail of the pitman-guide. Fig. 3 is a perspective in detail of the churn-receiving bracket' and the churn-embracing clamp.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invent-ion I construct a frame-work adapted to support the motor mechanism hereinafter described. This frame-work consists of four slanting supportin g-posts l, which at their upper en ds support a rectangular frame or bed 2.

In bearings formed in the upper edges of the frame 2 are mounted shafts 5 and 6. The shaft 6 is extended beyond one of its bearings and provided in this instance with an operating-crank 7, and between its bearings carries a master-gear 8. its bearings carries a small gear 9, which is engaged and driven by the master-gear 8.

At one end of the shaft 5 there is mounted thereupon a disk-wheel l0, provided with a series of pin-openings Il, each one of which is located at a different distance from the center of the disk from the others, and in one of said openings is inserted a removable pin l2, said pin being adapted for insertion in any one of the disks. The posts l also support a platform 13 near their lower ends, which platform below the disk l0 is provided with a semicircular recess or opening la. A supporting-bracket l5 surrounds the opening la and The shaft 5 between` depends below the same, and is adapted to support the churn-body 1G.

17 designates a clamping-arm pivoted to the platform, as at '18, and provided between its ends and at its inner edge with a substan- H 4which is adapted to be engaged by the free end of a latch 2l, pivoted to the platform, as at 22. By inserting the body of the churn in the bracket and the semicircular recess ll and swinging the clamping-arm 17 around against the churn and the latch over the shoulder of said arm it will be evident that the churn will be very substantially held in position and against any accidental displacement, while at the same time its ready removal is assured.

23 designates the dasher-staff, which is mountedinthe churn-bodyand passes through the cover 2a thereof. The upper end of the dasher-staff is connected to the disk-pin l2 by means of a pitman 2G, and through said staff and pitman is passed a pivot-pin 27.

28 designates a guide-bar, which connects the two posts l at that side of the frame-work at which is located the dasher-staff. This guide-bar is thickened at a point between the disk l0 and the churn, and in said thickened portion is formed a recess 29, the opposite side walls ofwhich are inclined toward each other toward their lower ends, so that said recess is adapted to serve as a guide for the dasher and the pitman at the joint between the two. In the movements of the dasher, as caused by the revolutions of the disk and the movements of the pitman, the inclined Walls serve as a means for breaking the joint formed by the pivot-pin 27, so that the pitman and the dasher are not maintained in alignment, and consequently said dasher is moved by the pitman up and downin a substantially vertical direction. By changing the points of connection between the pitman and the disk the dasher is given different lengths of movement, and is therefore adapted to churn different quantities of cream within the churnbody.

IOO

Having thus described my invention, what I claim is In achurn-motor, the combination, with the uprights and the frame supported by the 5 same, of ashaft journaled in the frame, means apart substantially corresponding with ther size of the joint between the flasher-Staff and Pitman,substantially as specified.

In testimony that I claim the foregoing as 15 my own Il have hereto affixed my signature in for rotating the shaft, a disk mounted on said presence of two witnesses.

shaft, a pitman connected loosely to the disk and to a dasher-staff, and a guide-bar located below the disk and having a recess provided 1o with opposite inwardly-inclined side Walls terminating at their lower edges at a distance TILLIAM JOSEPH MGEE.
