SPECIFIQATIQN forming part of Letters Patent No. 588,193, dated August 1-7, 1897.

Application iiled March 29, I897. Serial No. 629,689. (No model.)

Beit known that I, ASA BURTON TALROTT,

a citizen ofthe United States,residin g atCraigmoor, in the county of Harrison and State 5 of West Yirginia, ,have invented certain new and useful Improvements in Uhuru-Motors, of which the following is a specification, reference being had therein to the accompanying drawings. Y Y l This invention relates to chu rn-motors; and `it consists of the partsand the constructions and combinations of parts which I shall hereinafter fully describe, and point out in the claims.` f

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l represents a side elevation of achurn-motorembodyingmyinvention. Fig. 2 is a sectional view on the line :1; x of Fig. l. 2go Fig. 3 is a perspective view of the ydrip-cup into which the surplus lubricant is directed, whereby it is kept out of contact with the churn and its dasher. Fig. tis a perspective view of the swinging link carried by the crosshead, showing its socket into which the upper end of the dasher-stem is fitted.

In the 'drawings like letters of'l reference indicate corresponding parts throughout the several figures.

In carrying forward my invention I construct a frame or casing of suitable material and design adapted to support the4 operative parts and to house the gearing and power appliances through which the ch urn-dasher is reciprocated. Themotorfordrivingsaiddasher may be of any appropriate character, but is preferably of the typerknown as spring-motors, in which a windable spring A on a powershaft B drives a train of gearing which co-1n- 4o prises a gear-wheel ct on the power-shaft B, adapted to mesh with and drive a pinion t) on a shaft C, said shaft C carrying also a large gear-wheel c, which meshes with and drives a pinion d on a shaft D, said shaft` D having also a gear-wheel c, which meshes with and communicates mot-ion to a pinion f on a shaft E, having the well-known form of governor F. These parts may be ofv any well-y known form, and for the 'windable spring 5o may be substituted its recognized equivalent, a weight, without departing from the spirit of my invention,

The shaft D is extended through one side of the casing and has secured to it a wheel or disk G, provided -with a wrist pin or crank g, to which is pivot-ally connected one end of apitman or connecting rod H, whose opposite end is pivotally secured 'to the inner face of a cross-head vI, whereby said cross-head is vertically reciprocated by the rotation of the wheel or disk.

Projecting from the side of the casing on which is the-wheel or disk G are two lugs J, and to these lugs are secured the opposite ends of two parallel bars Or rods K, separated from each other to form a vertical guide for the cross-head to reciprocate in. The porvrtions of the rods which engage the cross-head vare preferably flattened, and theirinner edges or walls are designed to enter grooves formed in the sides of the cross-head, thereby forming an accurate and strongguide for the crosshead during the reciprocations imparted to it by the wheel or disk G and its pitrnan or connecting rod.

The parallelv guide-rods are sufficiently removed from the side of the casing to permit the wheel or disk Gr and the pitman to operi ate without danger of striking the rods, and that this object may be attained the rods are bent inward at their Opposite ends and secured to the lugs J before described.

In order that the crosshea`d may be removed for the purpose of cleaning or Otherwise, I prefer to pivot one of the guide-rods K at one end and so secure the opposite end by a set-screw h orother locking means that said latter end may be released and the bar swung laterally about its pivot and away from the `companion rod. This will expose the cross-head and allow it to be removed for any purpose whatever. V

Beneath the lower portions ot' the rods is a drip-cup M, which is designed to catch any oil or lubricant that may run down the rods or drop from the cross-head or other joints above and thereby prevent its finding its way to the churn and injuring it contents. l This protection to thecgontentsof the.. latter, and it is removably secured in position, so that it lnay be det-ached and cleaned when desired. In construction the drip-cup has a surround- 1 ing lia-nge to retain the drip, and at its inner drip-cup overhan gs the churn to give thebest Side is formed a downturned top or flange l, which is designed to pass into a slot made in the side of the casing, whereby any oil or lubricant entering the cup is directed inside of the casing and away from the churn and its flasher-stem. On the sides of the drip-cup are spring arms or clips m, which are adapted to spring over the lug to which the lower ends of the guide-rods K are secured when the cup is placed in position and which readily yield to permit the removal of the cup for cleaning purposes when a slight pressure is brought to bear on the cup. By this arrangement all possibility of oil running down the dasherstem or falling into the churn from the joints and parts above is obviated, thus insuring clean and wholesome butter.

The churn N is of the ordinary type and has a single vertically-reciprocating dasher. The flasher-stem passes through a socket n in the lower end of a link o, whose upper end is bent inward to one side of the plane of the stem, and it is pivotally secu red to the crosshead, so that the stem may have a yielding movement about the pivot on the cross-head. This will be found desirable, as the churn may be set a little to one side or the other of the true vertical line of the cross-head without danger of the stem being broken or cramped during its reciprocations, which would be the casein those churns in which the dasher-stem has a fixed or rigid connection with a crosshcad or other reciprocating piece. Through the socket end a of the arm is made a hole, and through this and a hole made transversely in the dasher-stem is passed a pin for securingthe parts together. The making of this hole is the only change required to it the ordinary single-dasher churn to this motor.

To stop the motion of the parts quickly and without jar, I employ a bra-ke which conconsists of a curved spring-plate P, which is pivoted at or near one end and carries at its free end a swinging rod Q, having a bend or offset at p, adapted to engage astud or lug o* on the side of the casing, said rod having also a handle-piece by which it is conveniently moved.

The spring-plate I has a second plate or shoe R secured to it between its extremities, which, when the rod Q is forced inward to canse the offset to engage the lug r, is caused to bear on the periphery of the wheel or disk I and serve as a brake t0 check its motion and the reeiproeation of the cross-head. \Vhen the rod Q is released, the spring-plate P lifts away from the disk, carrying the shoe with it, so that the disk is again permitted to rotate.

The invention described possesses the advantage of simplicity and ease of operation, durability, effectiveness, and cleanliness, and the motor may be connected with the com mon form of ehurns without any change in the form of the latter.

Having thus described my invention,what

I claim as new, and desire to secure by Letters Patent, is-

l. In a churn-motor, the combination,with the frame or easing, the operating-shaft having a wheel or disk on its outer end, and means for rotating said shaft, of the crosshead, a pitman or rod connecting the crosshead with the Wheel or disk and the parallel bars forming a guide for the cross-head, one of said rods being pivotally secured at one end to permit it to be swung laterally, and means for detachably securing the opposite or free end of said rod.

2. In a churn-motor, the combination, of a frame or casing, the operating-shaft, a wheel or disk on the outer end of said shaft, having a crank-pin, a pitman connected with said pin, parallel-spaced bars forming a vertical guide with one of said bars being pivotally secured at one end so that it may be swung laterally, means for dctachably securing the free end of said bar and xing said bar in position, a cross-head connected with the pitman and operating in the guide formed by the bars, and having grooved sides to engage said bars, and means for connecting the crosshead with the stem of a churn-dasher.

3. In a churn-motor and in combination with a reciprocating cross-head, and means for operating the same, and a vertical guide in which the cross-head travels, the means for catching the surplus lubricant or drip and keeping it ont of contactwith the churn, consisting of a drip-cup below the parts receiving the lubricant and into which the surplus oil or drip is directed.

4C. In churn-motors having a vertical guide and a reciprocating cross-head and means for operatingit, a drip-cup placed below the guide and cross-head for the purpose of receiving the surplus lubricant or drip, said cup having spring-arms engaging a lixed lug on the frame of the motor whereby it is detachably secured in position.

5. A churn-motor comprising a frame with lugs on its exterior, a spring-motor contained within the frame and including a driven shaft having a wheel or disk on one end, exterior 0f the frame, parallel-spaced bars having opposite ends secured to said lugs and theirintermediate portions bent outward, one of said bars being pivotally secured at one end so that it may be swung laterally, a cross-head adapted to reciprocate in the guide formed by said bars, a pitman connecting the crosshead with the wheel or disk, a drip-cup below the bars and cross-head, a brake for the wheel or disk and a pivoted link on the cross-head havinga socket in which the stein of the dasher may be secured.

In testimony whereof I aifix my signature in presence of two witnesses.
