CHURN.

SPECIFICATION forming part of Letters Patent No. 724,269, dated March 31, 1903.

'Application flied May 15, 1902. serial No. 107.473. ctt model.)

To a/ZZ whom it may conccrm' Be it known that I, CARTWRIGHT J. EDNEY, a citizen of the United States, residing at Shawnee, in the county of Pottawatomie and Territory of Oklahoma, have invented a new and useful Ohurn, of which the following is a specification.

This invention relates to mechanical movements, and has for its object to convert swing- 1o ing or reciprocatory movements into rotary or oscillating movements, and is furthermore designed to provide an improved operating device which is particularly adapted for actuating churn-dashers.

A further object is to arrange the device so that it may be mounted upon the Wall of a building or suitable upright support, so as to remain in a relatively fixed position, it being designed to apply and remove the churn-body zo Without removing or interferingr with the operating device, as occasion may demand.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within thel scope of the claims without departing from theV spirit or sacricing any ofl the advantages of the invention.

In the drawings, Figure 1 is a perspective View of a churning 'apparatus embodying the features of the present invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a detail sectional View showing the connection between the dasher-stem and the rotatable head. Y

Like characters of reference designate corresponding parts in all the figures of the drawings.

In carrying o ut the present invention there is provided a bracket or support consisting of an upright back 1, preferably formed bya board or plank which is tapered upwardly and provided near its lower end with outwardly directed vertically alined bracketarms 2 and 3, respectively, which are braced bearing, Whilethelowerarmisslightlyshorter j than the upper arm and has its outer end provided with a substantially semicircular notch or seat G to form a lower bearing. The back of the bracket is provided with a longitudinal series of perforations for the reception of suit- 6o able fastenings a, Vwhich project beyond the back and form means for securing the bracket to an upright support, as clearlj,7 indicated in Fig. 2 of the drawings.

An upstanding cylindrical rotatable head 7 65 is mounted between the two bracket-arms and is provided at its upper end with a reduced journal 8, which is mounted in the bearing 5, while its lower end portion is provided with a circular groove 9 to form a reduced inter- 7c mediate journal 10, `Which lits within the semicircularv bearing 6 in the lower bracket-arm, there being a bearing-cap 11 secured to theouter end of the lower arm.3 and embracing the intermediate journal of the head, so as to hold the latter in place. The lower end of the head, which projects a suitable distance below the lower bracket-arm 3, is provided with a longitudinal socket or seat 12 and a longitudinal notch or slot 13, formed in one 8o side of the head and communicating throughout its entire length with the seat, and a transverse opening 14 extends entirely through the lower end of the head and pierces theseat therein.

The dasher comprises a stem 15 and a plu-I rality of rods or bars 16, projected through transverse openings in the lower end of the stem and all lying in the same vertical plane. The upper end of the dasher-stem is fitted in 9o the seat or socket in the lower end of thelrotatable head and is held therein by means of a headed pin or key'17,'which passes through the opening 14; in the vhead and also pierces the stem. The pin also carries,l a; ,horiiontally-disposed fan 18, which is designed to work across the top of the churn-body, so as to prevent flies and other insects from settling upon the top of the churn. To hold the pin against displacement, a nut 17a may be used, as shown in Fig. 3.

Any ordinary form of churn-body, either a stone crock, a metal can, or a wooden bucket, may be employed, and therefore it has not been deemed necessary to illustrate any particular form of churn-body, as it forms no part of the present invention.

For manipulating the rotatable head there is a vertically-disposed approximately triangular oscillatory operating-frame composed of a pair of downwardly-converging arms or bars 19, which are pivotally connected to the upper end of the back of the bracket l by means of a single pivot-pin 20, the lower end portions of the arms being bracedv and c0nnected by a cross bar 2l, which lies just above the bracket-arm 2, thereby forming a substantially A-shaped swinging frame. The operative connection between the swinging arms and the rotatable head is afforded by means of the cords 22 and 23, respectively, which have their inner ends connected to the respective upper and lower ends of the head and their outer ends connected to the lower end portions of the swinging arms. The outer end of the cord 22 is connected to the lowermost extremity of the adjacent arm, while the cord 23 is connected at a distance from the lower end of the arm, so that the portion of the arm below the cord 23 forms a handle for manipulating the operating device. As the bracket-arms 2 and 3 lie in the path of the swinging arms 19, the former arms form stops to limit the movement of the swinging,r frame formed by the arms 19 and the cross-bar 2l.

That I claim isl. In a churn, the combination of a bracket comprising a vertical back designed to be secured to a wall or other support, and horizontal arms extending outward from the lower portion of the bracket and provided with bearings, a rotatable head journaled in the bearings of the arms and disposed vertically between the same and depending from the lower arm, a vertically-disposed approximately triangular oscillatory frame composed of converging bars pivoted at their upper ends to the bracket at the top of the back thereof and located at opposite sides of the horizontal arms, a rod connecting the bars and located above the said arms, a iiexible connection wound around the rotatable head at a point between the horizontal arms and connected with the bars of the oscillatory frame, and means located below the arms for the attachment of a dasher-shaft,l whereby the dasher-shaft and the churn-body may be removed without detaching the operating mechanism, substantially as described.

2. The combination with a rotatable member having a longitudinal socket in its lower y CARTWRIGI'IT J. EDNEY.
