GHURN.

Specification of Letters Patent.

Application filed June 5, 1911.

Patented Feb. 6, 1912.

Serial No. 631,251.

To all whom it may concern Be it known that I, THOMAS P. CALLIGOTT, a citizen of the United States, residing at Prescott, in the county of Nevada and State of Arkansas, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in churns of that type employing a vertical reciprocating dasher and has for its primary object the provision of simple and efficient means whereby the dasher may be easily and quickly connected or disconnected to and from the reciprocating pitman.

A further object of the invention is to provide a vertical frame having a crank shaft mounted therein, a pitman connected to the crank shaft, a sectional block connected to.

said pitman, and a novel guide-way for said block whereby the sections may be separated to remove the shank of the dasher whereby the same is disconnected from the pitman.

Another object of the invention is to provide a very simple and durable' construction of the above character, such construction enabling the dasher -to be removed and cleaned whereby the churn is maintained in a sanitary condition.

With the above and other objects in i iew,

the invention consists of the novel. features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the acconrpanying drawings, in which Figure 1 is a front elevation of a churn embodying my improvements; Fig. 2 is a section taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 2; and Fig. 4c is a detail perspective view of one of the sliding block sect-ions and a fragment of the dasher shank.

Referring in detail to the drawing 5 designates a vertical frame which consists of the lower spaced uprights or legs 6 and the body 7. This body is provided with a lon-- gitudinal slot 8. Upon the upper end of the frame a crank shaft 9 is mounted in suitable bearings 10, the crank 9 of the shaft being disposed in the slot 8 of the frame. To the crank 9 one end of a pitman 11 is connected, said pitman being adapted to work in the slot 8. One end of the crank 9 is provided with a handle 12 and to the other end thereof a belt wheel 13 is secured. This wheel is traversed by the driving belt 14 which passes around a belt wheel 15 mounted in a suitable bearing 16 secured to one of the spaced legs 6 of the frame. The shaft 17 of this lower belt wheel also has a hand crank formed on each of its ends whereby said belt may be moved to rotate the upper crank shaft 9 and impart reciprocatory movementto the pitman 11.

The body 7 of the frame structure below the slot 8 is provided with a vertical groove or channel 18 in line with said slot and in this groove the

sliding block sections

19 and 19 are arranged. These block sections at one of their ends are bifurcated as indicated at 20 and they are each provided with the bearing recesses 21 to receive the ends of a wrist pin 22 which is fixed in the lower end of the pitman 11. The block section 19 is rabbeted at its opposite longitudinal edges as indicated at 23 to receive the opposed edges of the movable retaining bar sections 25 which are hingedly connected tothe stationary sections 24 by means ofsuitable hinges 26. The'lower ends of the movable sections 25 are provided with suitable thumb screws 27 which are adapted to be threaded into the frame 5' to rigidly secure said movable sections upon the frame. When so disposed it s will be obvious that all tendency of the

block sections

19 and 19 to move out of the channel or groove 18 in the frame is overcome.

The lower ends of the sliding block sections 19 and 19' are also provided with the substantially triangular-shaped recesses 28 which receive the flared rectangular end 30 of the dasher shank 29. By thus connecting the dasher to the sliding blocks, it will be seen that in the operation of the device, a reciprocatory movement will be imparted to the dasher, and all liability of its disconnection from the sliding block sections is obviated while at the same time, when the churning operation is completed the dasher may be readily removed.

In the practical use of my invention, the churn vat or tub is arranged between the ends of the uprights or legs '6 of the frame which are preferably secured upon a suitable base, and the movable retaining bar sections 25 are raised. The outermost block section 19 is then lifted from the face of the other block section 19 and the flared end 30 of the dasher shank is seated in the recess 28 of the last named block section. The outer section 19 is then disposed upon the same, the bearing recesses 21 receiving the rights 6;

wrist pin 22 of the pitman. The lower movable bar sections 25 are then returned to I their normal positions and rigidly fastened upon the frame body by means of the screws 27. The device is now in condition to be operated by simply turning either of the

cranks

9 or 17. When the churning operation has been completed, the dasher is removed in a similar manner, so that it may be readily cleaned and the churn vat removed from'its position between the up- T the various parts, it will be understood that the device is susceptible of considerable I modification without'departing from the essential feature or sacrificing any of the adl vantages thereof.

Having thus described the is claimed is,:

l. The combination with a frame having a vertical guide-way, of a reciprocating piston and operating means therefor mounted in the frame, block sections arranged upon invention what each other and movable in said guide-Way, said pitman being pivotally connected at one end to said block sections, retaining bars be rigidly secured to the frame.

2. The combination with a frame, of a reciprocatory pitman and operating -means therefor, said frame having a guide-way, block sections slidable in said guide-way and pivotally connected to said pitman, one of said block sections having its opposite longitudinal edges rabbeted, said sections being arranged upon each other and provided in their opposed faces with recesses to receive the end of a dasher shank, retaining bars secured upon the frame and extending upon the rabbeted edges of said block sections, said bars each including a stationary section and a movable section hinged to the stationary section, and means for rigidly securing the movable retaining bar sections to the frame.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
