MOTOR FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 400,507, dated April 2, 1889.

Serial No, 294,203. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM H. STRIoK- LER and JAMES S. BRADDOCIQOitiZQDS of the United States, residing at Mount Pleasant, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Motors for Chorus, of which the following is a specification.

The invention relates to improvements in' motors for churns; and it consists in a certain novel construction and combination of devices, fully described hereinafter in connection with the accompanying drawings, and specifically pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a churn-motor embodying our invention. Fig. 2 is a vertical longitudinal sectional View of the same. Fig. 3 is a transverse central sectional view thereof. Fig. 4 is a rear view. Fig. 5 is a front view, partly broken away, of a portion of the motor to show the device for winding the drum and spring. Fig. 6 is a plan View of the same, showing a winding-key applied in the operative position to the arbor.

Referring by letter to the drawings,A designates the supporting-frame for the operating mechanism, which is provided with vertical standards a a, respectively, at its front and rear sides, and B designates a transverse horizontal verge, which is mounted in suit-able bearings in the said standards.

0 O designate vibrating arms, secured at their centers to the verge near the ends of the latter and beveled on their upper edges from the center toward the ends, and D designates the churn-tub, which bears on the upper edges of the said arms andis secured thereto'by suitable means. The bottom of the churn-tub is inclined upward from its ends toward the center to fit the upper edges of the arms 0.

A suitable cover, E, is fitted in the opening e in the upper side of the churn-tub, and breakers F F depend from the opposite sides of the said opening and extend transversely across the tub. These breakers consist of a series of vertical bars, ff, connected at their ends by the horizontal bars f f, and they are designed to swing to and fro as the churnbody is oscillated. One of the arms Ois provided with vertical ears 0 0, having inwardlyprojecting pins 0 c, which fit in sockets in the sides of the churn-tub, and the other arm is provided with a hasp 0 or a similar securing device.

On a horizontal arbor, G, which is mounted in suitable'bearings in the supporting-frame, is arranged the scape-wheel H, which is engaged by a pallet, I, at an intermediate point of the verge, and K designates a power-shaft, mounted on the supporting-frame and provided with a main wheel, K, which meshes with a pinion, G, on the arbor G. v An operating-spring, L, is arranged on the power-shaft to rotate the same, and thereby cause the rotation of the arbor and the scapewheel, and M designates a drum mounted on the shaft K adjacent to the main wheel, and provided with a ratchet-Wheel, k, which is engaged by a pawl, It, on the said wheel, to lock the drum rigidly on the shaft. A cord, 0, is wound on the said drum,passes around an idler-pulley, P, on the arbor G,passes over a pulley, p, at the upper end of the standard a, passes through the pulley-block P, and 1s attached at its end to the said standard. A weight, Q, is engaged with a hook, q,on the said pulley-block to assist the spring L 111 the rotation of the power-shaft. The spr ng and the Weight may be wound up by rotatlng the said shaft by means of a key, 10 (Shown detached in Fig. 6.) R designates a short spindle mounted on the supporting-frame and provided with a pinion, 1, which meshes with a similar pinion, r, on-the drum, whereby the said drum may be rotated independently of the main shaft. This construction is designed to enable the cord to be wound on the drum in the opposite direction to that shown in the drawings, whereby the weight will act against the spring in order to reduce the power thereof when the latter is too great.

S designates a pendulum provided at its upper end with a hook, s, engaged with a suit able pin, 3', and T designates a depending arm on the verge, which is provided at its lower end with a finger fitting in-a longitudinal slot, S, in the pendulum.

The pendulum is provided near its lower end with a series of perforations, U U, and the pendulum-bob V, which fits on the pendulum, is provided with a perforation, v, adapted to register with either of the perforations in the pendulum. A pin,V, engages the said registering perforations to secure the bob at the desired point of the pendulum.

The operation of the improved churn will be readily understood from the foregoing description. The churn-tub, which is mounted on the verge, is oscillated by the force of the spring and weight acting through the gearing and escapement, and the contents of the tub are dashed from one end thereof to the other over the double-inclined bottom, the breakers serving to increase the agitation of the same. The bob is lowered or elevated on the pendulum to suit the weight of the contents of the tub, the object thereof being to counterbalance the weight of the contents.

\V W represent vertical buffers arranged under the ends of the churn-tub and provided at their upper endswith the coiled spring 10 w, against which the ends of the tub alternately strike as the latter is oscillated. The springs aid in changing the direction of the swing of the pendulum and prevent the same from swinging too far.

Having thus described the invention, we claim 1. The combination of the tub mounted on a verge which is provided with a pallet engaging a suitable scape-wheel, and the powershaft geared to the shaft of the scape-wheel, substantially as specified.

2. The combination of the verge carrying a churn-tub and having a pallet which engages a suitable scape-wheel, the power-shaft geared to the shaft of the scape-wheel and provided with a power-spring to rotate the shaft, the drum mounted on the power-shaft and adapted to be locked rigidly thereto, and the cord coiled on the drum and provided at its opposite end with a weight, substantially as specified.

3. The combination of the verge carrying a churn-tub and having a pallet which engages a suitable scape-wheel, the power-shaft provided with a spring and geared to the shaft of the scape-wheel, and the buffers arranged under the ends of the churn-tub and provided at their upper ends with coiled springs to to, which are adapted to be alternately compressed by the churn-tu b, substantially as specified.

4. The combination of the verge provided with the rigid vibrating arms 0 C, the churntub removably secured to the said arms, the pallet arranged on the verge and engaging a suitable scape-wheel, and the power-shaft geared to the arbor of the scape-wheel, substantially as specified.

5. The combination of the verge provided with the arms 0 O, beveled on their upper sides froin'their centers toward the ends, the churn-tub provided with a double inclined bottom'fitting on the upper edges of the said arms and removably secured thereto, the escapement arranged as described, and the power-shaft geared to the arbor of the scapewheel, substantially as specified.

6. The combination, with the verge having the churn-tub attached thereto and provided with a pallet engaging asuitable scape-wheel, and the power-shaft geared to the arbor of the scape-wheel, of the pendulum suspended loosely 011 a suitable pivot-pin and the depending arm at the verge fitting at its lower end in a slot in the pendulum, substantially as specified.

7. The combination, with the verge having a churn-tub attached at its center thereto and provided with a pallet engaging a suitable scape-wheel, and the power-shaft geared to the arbor of the scape-wheel, of the pendulum pivoted at its upper end and provided with a series of perforations, U, the depending arm T on the verge provided with a finger, t, fitting in a vertical slot in the pendulum, the pendulum-bob fitting on the lowerend of the pendulum and provided with a perforation registering with one of the perforations U, and the pin engaging in the said perforations, substantially as specified.

S. The verge provided with the vibrating arms 0 C and the depending arm T, the churn-tub secured to the arms 0, the pallet on the said verge engaging a suitable scapewheel, and the power-shaft geared to the arbor of the scape-wheel, in combination with the pendulum pivoted at its upper end and connected to the lower end of the arm T, and the pendulum-bob fitting on the lower end of the pendulum and vertically adjustable thereon to counterbalance the weight of the contents of the churn-tub, substantially as specified.

9. The combination, with a verge carrying a churn-tub and provided with a pallet engaging a suitable scape-wheel, and the powershaft geared to the arbor of the scape-wheel and carrying an actuating-spring, of the drum loosely mounted on the power-shaft and having a weighted cord wound thereon, and the pawl engaging a ratchet-wheel on the drum to lock the latter to the power-shaft, substantially as specified.

10. The combination, with a verge carrying a churn-tub and provided with a pallet which engages a suitable scape-wheel, and the powershaft geared to the arbor of the scape-wheel and carrying an actuatin g-sprin g, of the drum mounted loosely on the power-shaft and having a weighted cord wound thereon, the pawl engaging a ratchet-wheel on the drum to lock the latter to the power-shaft, and the supplemental shaft R, adapted to be engaged by a key and geared to the drum, substantially as and for the purpose specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
