Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed May 6,1904. Serial No. 206,637.

To all whom it may concern.- Be it known that we, CHRISTOPHER Y. Mc- CARDLE, a resident of Cameron, county of Marshall, and SILAs N. DAVIS, a resident of Elm Grove, county of Ohio, State of West Virginia, citizens of the United States of America, have invented certain new and useful Improvements in Ohurning Apparatus, of which the following is a specification.

Our invention relates to new and useful improvements in churns, and more particularly to a churning apparatus; and it consists in the particular construction, arrangement,

and combination of parts, which will hereinafter be fully described.

The object of our invention is to provide a simple and durable apparatus or machine for churning which on account of the speed at which it can be driven and because of the double or duplex movement of the dashers facilitates and at the same time lessens the labor of churning.

In describing the invention in detail reference is herein had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of the invention. Fig. 2 is a top plan view of the same, showing the movable horizontal sections and brace swung outward; and Fig. 3 is a front elevation of a broken section of the invention.

Referring to said drawings, in which like reference-numerals designate like parts throughout the several views, 1 indicates a base on which is mounted a churn-body 2. On said base at each side of the space occupied by said churn-body 2 is an upright support 3. J ournaled in said supports is a shaft 4, having two oppositely-disposed cranks 5 therein, and on one end of said shaft is a small gear-wheel 6, which meshes with a large gear-wheel 7, mounted to be rotated by a hand-crank 8, which is supported in any suitable manner, a post 9, mounted on the base 1, being illustrated in the drawings. Having their upper ends attached to said cranks 5 are two toggle-arms 10. The lower end of one of said arms is pivoted to the upper end of a vertical rod 11, and the lower end of the other arm is pivoted to the upper end of a second vertical rod 12. Said rod 11 is shorter in length than the rod 12 and carries upon its lower end a dasher 13, while the rod 12 car ries upon its lower end a dasher 14. Said rods, with their dashers, stand suspended Within the churn-body 2, as shown, with the dasher 13 preferably directly over the dasher 14. Said rods are secured to said dashers at points outside the center thereof, and the dasher 13 travels up and down on the rod 12, an opening or passage being provided in said dasher, through which said rod passes. One or more horizontal cross plates or braces 15 are secured at their ends to said supports and serve as braces for said supports and for the rods 11 and 12. Semicircular recesses 16 are provided in the front edges of said braces 15, in which said rods 11 and 12 partially lie. Horizontal sections 17, hinged or pivoted at one end on one of the supports 3 and having their rear edges shaped to correspond with the front edges of said braces 15 and also provided with recesses 18 for engaging said rods 11 and 12, are provided to fit against said braces 15 to embrace and hold said rods in vertical position. The lower of said braces 15 is preferably located at a point just above the top of the churn-body 2 and has therein set-screws 19, which are adapted to be manipulated to cause their points to impinge upon, and thus firmly hold, the lid 20 of the churn in place upon the body 2.

A fixed brace 21 is provided on the base 1 at the rear side of the churn-body, and a movable brace 22, pivoted at 23, is adapted to hold the churn-body firmly in place while the machine is in operation. A pivoted hook 24 holds the free end of the brace 22 in place, while hooks 25 are provided for holding the sections 17.

In operation the turning of the hand-crank 8 revolves the shaft 4, and consequently the toggle-arms attached to the cranks 5 raise and lower said rods 11 and 12 alternately, producing what may be termed a double or duplex movement or stroke of the dash ers, they moving toward and away from each other alternately.

To remove the churn-body from the machine, the movable brace 22 and the sections 17 are swung outward, the pins or pivots 26, which secure the toggle-arms to the rods 11 and 12, are removed, and the set-screws 19 are released, when the churn-body and the rods and dashers are entirely disengaged from the machine and may be removed together.

As is obvious, any kind of motive power desired may be employed for operating the machine. A pulley-wheel may be mounted on the end 27 of the shaft 4, so as to admit of the driving of the machine by belt. Instead of gear-wheels, shown in the drawings, sprooket-wheels and a chain may be employed, if desired.

We have described our invention more or less in detail; but it is obvious that various slight changes may be made in the construction and arrangement of some of the parts composing the invention without departing from the general spirit or scope thereof. Hence we do not wish to limit ourselves to the precise construction and arrangement herein shown and described.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

In a device of the character described, the combination with a churn-body, of a frame, a shaft with oppositely-disposed cranks thereon mounted in said frame over the churnbody, links connected with said cranks, rods carrying dashers depending from said links within the churn-body, pivots connecting said rods with said links, said pivots being adapted for removal to admit of said churnbody and said rods being together removed from the frame, pivoted braces having semicircular recesses therein embracing said rods and holding them in vertical alinement, the lower of said braces located directly above the churn-body, set-screws extending vertically through the last-mentioned brace for impinging directly upon the churn-lid to hold it in place upon the churn-body, and gearing for driving said shaft, substantially as described.
