CHURN-MOTOR.

SPECIFICATJON forming part of Letters Patent No. 282,389, dated July 31, 1883.

Application filed June 25, 1883. (No model.)

To aZ Z whom, it may concern:

Be it known that we, GEORGE E. SMITH and GEORGE H. SMITH,= of Latrobe, in the county of Athens and State of Ohio, 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 enableothers skilled in the art to which it appertains to make and use the same, refeience being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of our improved chu rnmotor. Fig2 is a View from the opposite side, showing part of theframe broken away.

Similar lettersi'of reference indicate corresponding parts mall the figures.

Our invention has relation to mechanical powers of that class in which a'churnqnotor is adapted to give either rotary reciprocating or rotary motion to the dasher of the churn',as

may be desired and it consists in the improved construction and combination of parts of the same, as will be hereinafter more fully described and claimed.

In the accompanying drawings, A represents the frame which supports the clock-movement B, which is of ordinary construction. This movement may be operated by an ordinary clock-spring, or,.as shown in the drawings, by a weight, D, fastened to the free end of a cord, E. This cord'passes over a pulley, F, heldbetween the upper extremities of the arms G, secured to the top of the frame and extending upward, the arms being of such a length as to raise the pulley F sufiiciently above the ground to allow the. cord E to run out before the weight D touches the ground.

H represents a solid metal eccentric secured upon the upper shaft or axle of the train B, and having an annular groove or recess, I, into which a metallic strap or band, J fits. To

the end of the axle K which projects outside of the frame is attached a fly-wheel, K.

L represents a pitmanbolted or riveted at one endbetween the endsof the band J, thefree end of the pitman being rounded to form a convenient handle, M. A shaft or axle, N, is j our- .1 naled in the upper part of the frame A, having at its central part a double crank, 0. To the shaft N is also fastened a downwardly-,proj ecting rod, I, having its lower end bent at right angles. A bevel-whee1, Q, on the end of the shaft N meshes with a bevel-pinion, It, on the upper end of the dasher-rod. The pitman L has a slot, S, in its lower edge, near the handle bent end of the rod 1?, when, as will readily be understood by reference to'the drawings, the eccentric I-I, turning upon its axle, will com- .municate to the churndasher,through the intermediate gearing previously described, a rotary reciprocating motion. WVhe'n it is desired to give the churn-dasher a rotary motion, however, by taking hold of the handle hf of the pitman the bent end of the rod I? can be freed from the slot S on the lower edge of the pit man, when the free end of the pitman can be raised, in order to connect the said end by means of the slot in its under edge to the pin of the crank 0, when a rotary motion will be given to the churndasher.

T represents a brake pivoted at one end to the outside of the frame A, just above the out wardly-projeeting end of the axle K, which carriesthe fly-wheel K, previously referred to. This brakeis held out of the way of the axle K, when not in use, by a'keeper, U, pivoted atone end to the outside of the frame A. The object of this brake is to regulate the speed with which the eccentric H revolves, and through it the speed of the churn-dasher. On the upper edge of the handle of the brake T are a series ofnotches, V, in which fits thering or hook of a weight, WV. hen it is desired to lessen the speed with which the motoris running, the brake T is freed from the keeper U and pushed down until its lower edge rests upon the rod or axle K, between 'the side of the frame and the fly-wheel K. The weight is then adjusted upon the notched edge of the brake, in order to regulate the amount of pressure which the brake exerts upon the said axle, the weight being of such a size that, when adjusted upon the extreme outward end of the handle of the brake, it will cause the motor to come to a dead-stop. When it is is desired to free the axle from'the brake, the brake is lifted up until it engages the end of the keeper U.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of our improved churn-motor will readily be understood'without requiring extended explanation.

It will be seen that by constructing the eccentric of solid metal, its weight, being chiefly on one side, will effectually overcome the tendency of the running-gear to stop when it reaches its dead-center.

Having thus described our invention, we

claim and desire to secure by Letters Patent of the United States- 1. In a churn-motor of substantially the described construction, the combination of the frame A, having pivoted keeper U, drive-shaft K, having flywheel K, mechanism for oper ating the drive-shaft, and brake T, having adj ustable weight W, substantially as and for the purpose shown and described.

2. In a churn-motor of substantially the described construction, the combination of the shaft or axle N having on its end a bevelwheel, Q, adapted to mesh with a bevel-pinion, R, on the end of the dasher-rod, and provided with a double crank, O, and downwardly-projecting arm P, arranged as described, weighted eccentric H, provided with an annular groove, I, band J, and pitman L, having at its outerend an upwardly-extending notch, S, adapted to engage either the bent end of the arm P or the pin of the crank 0, all constructed and combined substantially as and for the purpose shown and described.

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