To all whom it may concern:

Be it known that I, CLINTON M. WOLFE, a citizen of the United States of America, residing at Coeburn, in the county of Wise 5 and State of Virginia, have invented new and useful Improvements in Ghurns, of which the following is a specification.

The present invention relates to improvements in churns, and particularly to certain novel combinations and arrangements of the operating and actuating mechanisms of the device. Tlie primary object of the invention is to improve the construction of churns by providing a blade or paddle device which is efficient in operation, durable, and at the same time may be operated with facility and comparatively slight expenditure of energy to agitate the cream in order to make the fatglobules unite to form butter. The invention consists essentially in certain novel combinations and arrangements and structures of the dasher blades and their operating devices whereby the action of the churn is greatly enhanced and increased.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, constructed according to the best mode I have so far devised for the practical application of the principles of my invention, and this form of the invention has already proven highly satisfactory in actual use.

Figure 1 is a. side elevation of the complete churn, parts being shown in section, illustrating an apparatus made according to my invention. 4

Fig. 2 is a side elevation, at right angles to the parts shown in Fig. 1, depicting the dasher and connections.

Flg. 3 is a detail, fragmentary, view show- 'n' the construction of the slidable hinge it) t of the dashor.

Fig. 4 is a fragmentary view showing, partly in section, the e onnection between the pitman rodan the link,"

Fig. 5 is an enlarged sectional detail view showing the connection between the stationary hinge joint and the supporting spindle of the churn.

Fig. 6 is a sectional view on line 6-6 of Fig. 2.

In the preferred embodiment of my invention as shown in the drawings I utilizethe,

usual barrel or receptacle 1 which may be. of suitable or desirable material, together" with the customary frame 2 upon which the actuating and operating mechanisms are supported.

, Within the barrel or receptacle 1, a supporting spindle 3 is located andvfixed inqgo suitable manner, as in the seat 4, and the- H spindle projects vertically upward through the barrel as indicated.

As will readily be seen the spindle 3 is designed to support the dasher of the churn, 55 which dasher may be described as comprising a set, or two pairs of hinged blades designated as 5, (3, 7, 8, which are hinged together in pairs as at 9 and 10, and then the pairs are hinged together at 11 and 12. The hinge joint 9 is a stationary one, the pin 13, 13, of the hinge, being passed through opening 15 of the spindle 3 and having at one end handle 13 and at its other end a cotter pin 13. There are three of these openings 15 illustrated in the drawings, but the number may be increased or decreased as desired, so that the dasher may be adjusted in its altitude with relation to the bottom of the churn barrel. The hinges 11 and 12 are folding hinges so that the upper and lower pairs of blades may be folded outwardly at the center of the dasher, (see dotted lines Fig. 2) as the churn is operated. The hinge joint 10 at the upper end of the dasher between the two blades 7 and 8 is a slidable joint, and to accomplish this purpose the hinge pins 16 of this joint are seated in diametrically arranged recesses or notches 17, 17, in the bushing or sleeve 18, of a vertically reciprocable link 19 which is operated by means of the pitman 20. The joint between the link and its pitman is adjustable in order to lengthen or shorten the reciprocating parts. Thus, the lower end of the pitman is screw threaded as at 21 and a turn buckle 22 is threaded thereon, a lock nut 23 being utilized to prevent turning of the buckle. The buckle is provided with a bifurcated end and the two arms or forks thereof, as 24, 25 are perforated at their extremities for passage of the locking pin 26 carried at the end of the spring arm 27 which is attached to the buckle at 28. The upper end of the link is perforated as at 29, 29, 29, for the passage of the pin 26, and by using different ones of these perforations, a long orshorter connection may be provided between the link and pitman.

The link reciprocates vertically through a holds the spindle 3 steady and stable.

perforated transversely arranged horizontal brace arm 30 which guides the link, and aloso n its under surface the guide baror arm 30 is recessed as at 31, adjacent the guide opening 32, so that the head of the spindle is encased therein and the spindle held rigid between'this braceor guide arm and the bearing block or seat 4 on the bottom of the churn barrel.

The guide arm 30 is pivoted in the frame at 33, and extends across to the oppositeside of the frame where it may be latched as at at to hold or retain it in o erative po-' 'sition, and'a pivoted latch 30 is used to guide the link 19.

Reciprocating movement is im arted to i the pitman through the crank sha t 35 journaled at'the upperend of the frame and the pinion 36 on this shaft by means of the gear 37 and handle 38, supported in the frame and meshing with the pinlon.

The blades of the dasher are provided with a suitable number of openings 39 through which the cream is passed as the v folding dasher is opened and closed. The operation of the apparatus will Ice-evident,

and it is hardly necessary to give a detailed description, However it will readily be seen 30 that when the crank shaft 35 is rotated through the gears 37 and 36, the-pitman and its linkare caused to reciprocate through the brace 30, with the result that the blades of the dasher are caused to fold and unfold on their hinges with a contracting and dis tending movement as indicated in Fig. 2.

The cream is thus forced through the openings 39 in the blades and port 39 between ings therein, a pair, of oppositely located blades having a hinge pin passed through;

one of the openings in the spindle, a pair of blades hinged to the free ends of the first pair of blades, a pitman connected to the operating means and a link connected to the pitman, a bushingintegral with the link and adapted to slide on the spind1e,'and a hinge said bushing.

. In testimony whereof I aflixiny si nature. CLINTON M. WoiirE.
