SPECIFICATION forming part of Letters Patent No. 443,720, dated December 30, 1890.

Application filed August 21,1890. Serial No. 362,623. (No model.)

To all whom it may concern.-

Be it known that we, JOHN CHERRY and GEORGE CHERRY, citizens of the United States, residing at Berea, in the county of Box Butte and State of Nebraska, have invented certain new and useful Improvements in Churn-Motors; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to churn-motors; and it has for its object to provide in combination with a churn a simple and efficient motor adapted to impart a vibrating motion thereto and provided with means for governing the speed.

A further object of the invention is to provide an improved motor of the character described which will possess advantages in point of inexpensiveness, durability, ease of 7 preferably, of metal or wood, and in any suitable or ornamental design, said ends being connected by rods a. Between the ends a is journaled a main or power shaft B, carrying near one end a gear-wheel G, loosely mounted thereon. Adjacent the gear-wheel O and rigidly secured to the shaft is a ratchet-wheel c, engaged by a pawl c, pivoted to the gearwheel and held in engagement with the ratchet-wheel by a spring 0 carried by the gearwheel. Power is transmitted to the shaft 13 by a coil-spring D, as shown, having its inner end secured to the shaft and its outer end to one of the rods a, or bya cord adapted to be wound upon the shaft and carrying a weight at its free end. For winding the spring or cord upon the shaft, the end of the latter opposite the gear-wheel C is extended through the adjacent end of the stand, and is formed angular for the engagement of a crank or key.

E designates an auxiliary shaft journaled between the ends a and provided with a rigid pinion 6, located adjacent the gear-wheel C. An intermediate shaft F is also journaled between the ends of the stand and provided with a rigid pinion f and gear-wheel f, respectively adapted to mesh with the gearwheel 0 and pinion e and transmit motion to the shaft E from the shaft B. If desired, two or more intermediate shafts and gearing may be employed.

The end of the shaftE adjacent to the pinion e is extended through the frame, and is provided with an arm E at right angles to said shaft. This arm is connected by a pitman with a reciprocating arm F, journaled at its lower end to the adjacent end a of the frame and provided at its upper or free end with a loop or guide f projecting at right angles thereto, the purpose of which will be hereinafter setforth.

G designates the churn-body, constructed of wood or sheet metal and rectangular in shape. This churn-body is provided with a removable cover G, having a flange 9 around its edge adapted to fit over the churn-body. For retaining the cover in place two springcatches g g are provided, consisting each of a spring-plate secured to the churn-body at the ends thereof, and having its free upper end bent inwardly, so as to project over the cover. The churn-body is provided with supports H H, journaled at the top of the ends of the frame. The latter bearing is extended beyond the frame and turned down, passing through the loop or guide f at the top of the reciprocating arm and adapted to be carried by the latter during its movement to vibrate the churn-body.

The foregoing construction of churn-body is the one we prefer to employ in connection with our improved motor, though it will be obvious that this is not essential to our invention, and that any other suitable or desired churn-body may be employed without departing from the spirit and scope of our invention.

For governing and regulating the speed of the motor, an arm I is provided, rigidly secured at" its upper end to the lower end of the support H. Upon the arm I is disposed an adjustable weight J, provided with a central perforation j, through which said arm passes. The weight is preferably secured in the position to which it is adjusted by a setscrew j, passed through one side thereof and adapted to be bound to the arm I. 'It will be apparent that by constructing the arm I of spring material a rebound of the weight is caused at the completion of its movement in one direction, and the resistance to the power of the motor is thus materially lessened.

The operation and advantages of our in vention will be readily understood by tho=e skilled in the art to which it appertains. The motor being wound and the matter to be churned placed within the receptacle therefor, the

' weight or pendulum is adjusted to the desired point upon the spring-arm. This adjustment is rendered expedient by the amount of matter to be churned. Thus thelarger the quan tity of the contents of the ohurnbody the greater the leverage required upon the sp ri ngarm, and the weight is accordingly adjusted nearer to the lower end of said arm. The operation of the motor serves to reciprocate the arm F, and the extended bearing H of the churn-body being carried thereby in its movement vibrates the latter, and consequently agitates the conten ts thereof for the purpose of churning. The employment of a spring-arm for the governor or regulator in lieu of a rigid arm effects a rebound of the weight at the completion of a stroke, and thus serves to overcome the resistance to the power of the motor, and also to carry the arm at the end of the auxiliary shaft beyond a dead-center and enforce a continuous op eration of the motor.

We claim as our invention 1. The combination, with a churn-motor, of an oscillating governor or speed-regulatorconsisting of a spring-arm and a weight carried thereby, said arm being adapted to effect a rebound of the weight at the completion of a stroke, substantially as and for the purpose set forth.

2. The combination, with a churn-motor comprising a power-shaft, an auxiliary shaft provided at one end with an arm at right angles thereto, and a reciprocating arm connected with said arm by a pitman and adapted to be connected to a churn-support to vibrate the churn, of a governor consisting of a springarm secured to said churn-supp0rt and a weight carried by said spring-arm, substantially as set forth.

A churn-motor comprising a reciprocating arm adapted to carry an extended churnsupport throughout its movement, and an oscillating governor consisting of a springarm and a weight carried thereby, substantially as and for the purpose set forth.

4. The combination, with a churn-motor embodying a reciprocating arm adapted to carry an extended churn-support to vibrate the churn, of a governor consisting of a spring arm and a weight carried thereby and adjustable thereon, substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
