CHURN-MOTOR.

SPECIFICATION forming part of Letters-Patent No. 300,620, dated June 17, 1884-.

Application filed April 25, 1884. (No model.)

To all whom it may concern:

- Be it known that I, JOSEPH L. MOKAY, a citizen of the United States, residing at Neoga, in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in Churn-Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of churnmotors which employ a spring-power mechanism acting upon the dashers.

The object of my improvements is to provide a simple and improved motor which will possess advantages in point of ease of operation and general efficiency, and which can be governed and adjusted-with superior convenience and facility.

In the drawings, Figure 1 is a perspective view showing my improved motor in position upon the churn. Fig. 2 is a side elevation thereof, the side of the casing being removed and parts of the interior frame being broken away to show the construction. Fig. 3 is an end view of the same, part of the casing being removed. Fig. 4. is a detail side view of the balance-wheel mechanism. Fig. 5 is a detail sectional view taken through the balancewheel mechanism. Fig. 6 is adetail side view showing the retainingspring of the lock or stop mechanism. Fig. 7 is a detail perspective view of the top or cover of the churn, the motor-casing being removed. Fig. Sis a vertical transverse sectional view in detail, taken through the standard and the top or cover to which it is secured. Fig. 9 is ahorizontal detail sectional view'taken 011 the line a: m, Fig. 8. Fig. 10 is a detail sectional view illustrating the means for securing the motor-casing in position on the top of the churn.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the top or cover of a churn, which is fitted to the body of the churn (shown in dotted lines) in any desired manner, and may be of any suitable construction. A perpendicular standard is provided upon the top A, and is preferably its side and top edges, as shown.

formed by two parallel standards, B B, having bearings at their top for a transverse shaft, 0, carrying a gear-wheel, D, arranged between the said standards. Each standard B is provided with a vertical guide-slot, b, in whichworks an approximately H shaped sliding head, E, havingalateral projection, e, in which one of the da'sher-staffs is vertically adjustable by means of a set-screw, F. The shaft 0 is provided with oppositely-cranked endsc c, from which extend rods or pitmen G G, which are pivotally connected at their lower ends to the heads B. By this arrangement the rotation of the shaft 0 causes the heads E to reciprocate vertically and in opposite directions, thus imparting a reciprocating motion to the churn-dashers. A perforation, a, is provided in the top A at each side the standard, through which the dasher-staffs work, the staffs being designated by the letter H.

I designates the casing which contains the motor mechanism, and comprises an interior frame, J, to which the casing is secured. This casing J comprises side pieces, j j, forming bearings for the motor mechanism, and provided with inwardly-proj ecting flanges j at The side pieces or boards, 1' i, of the/casing proper are secured to the sides j j of the interior frame by means ofscrews, or in. any other suitable manner. The ends and top of the casing are preferably formed by a single bent strip, '6, which is secured to the inwardly-projecting flanges j in any suitable manner. Openings 2' are preferably provided at the bottom of the sides i, through which the-motor mechanism may be conveniently inspected.

Transverse flanges K K project from the bottom of the interior frame, J, at each end of the casing, by means of which the latter is secured in position upon the churn top or cover. At one side of the top A is provided a plate, L, having a lip, Z, under which one of the flanges K is adapted to be adjusted, and upon the opposite side of the top A a plate, M, is adapted to be adjusted over the other flange K, to lock the casing in position. This plate M is provided with end slots, at m,which receive guide-pins n12, projecting from a baseplate, N, secured upon the top A, and the said plate M is also provided with a projecting lug, m, by which it may be operated.

A suitable spring-motor mechanism similar to that used in clocks or other devices is pro-' vided within the casing, this mechanism being adapted to be wound up by a suitable key, and embodying a train of gear-wheels, the lower one of which, 0, is adapted to mesh with the gear D when the casing is secured in position on the top A and over the upright standard. By this arrangemen t, when the casing is secured in position and the spring mechanism is wound up, the motor mechanism will trans: mit a rotary motion to the shaft 0, and the churn-dashers will be reciprocated vertically, as before specified. The speed of the motor mechanism is governed by turning a pin, 1?, which projects through an opening, i in one side of the casing, and is provided with an in dicator or finger, 1;, moving over the face of the casing. The inner end of this pin 1 is provided with an angular arm, p, whicln engages the balance-spring Q, and serves to reg ulate the same. A spring-plate, It, is interposed between the arm 19 and the inner face of the casing J, and serves by its tension to retain the regulating-pin in the position to which it has been adjusted. The shaft S of the balance-wheel has its bearings in the ends of set-screws T T, working through the sides of the casing J. The head of one of these screws preferably projects through a perforation, 6', in the side of the casing, while the head of the other screw projects through the perforation i" at the other side, by which arrangement the screws may be conveniently adjusted to regulate the bearing of the balancewheel shaft.

U designates a transverse angular rod, which has its bearings in the frame J, and is pro vided with a head, a, projecting through a perforation, a", in the side of the casing. By simply turning this head the rod U is brought into engagement with the teeth of the gearwhecl 0 when desired to stop the operation of the motor. By turning the head in an opposite direction the stop mechanism is disengaged from the teeth of the gear 0, and the mechanism will automatically resume its operation. A spring-plate, V, is interposed be tween the crank of the rod U and the inner face of the casing J, and serves by its tension to retain the stop -rod in any condition to which it is adjusted.

Suitable bails or handles, V W, are provided upon the ends of the casing, by which the motor mechanism may be conveniently lifted from the top of the churn after the operation of churning has been effected.

From the foregoing description and annexed drawings the operation and advantages of my invention will be readily understood.

The motor mechanism can be readily and conveniently connected with or disengaged from the churn, and its speed is easily regulated and governed while it is in position and during its operation. The casing has simply to be applied to the churn top or cover and fastened in position, when the mechanism is wound up, and will then automatically effecta quick and thorough churning.
