" IMPROVEMENT lN GEARINGS.

Specification forming part of Letters Patent No. 160,181, datedFebruary 23, 1875; application filed December 7, 1874.

To all whom it may concern:

Be it known that l, HORACE L. GORDON, of West Garland. in the county of Penobscot and in the State of Maine, have invented certain new and useful Improvements in Churn-Gear; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a churn-gear, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view of my churn-gear arranged for fast motion. Fig. 2 is a side view of the same. Fig. 3 is a plan view of the gear arranged for slow motion, and Fig. 4 is a view of the elbow-lever which carries the double gear-wheel.

A represents a plate of any suitable size and shape, and provided at one end with an outwardlyprojecting hollow stud, B, through which passes a shaft, to, into one end of the churn-dasher shaft. On the outer end of the shaft a is secured a pinion, 0, formed with a circumferential projecting flange, b, on the inner side. Near the other end of the plate is pivoted an elbow-lever, D D, the long arm, D, of which is provided at its outer end with a knob, d. The short arm, D, of the elbowlever is provided with a stud, E, upon which is placed a double cog-wheel, G G, provided with a crank or handle, H. The part G of the double cog-wheel is of large diameter, while the part G is of smaller diameter. I and 1 represent two flanged buttons pivoted on opposite sides of the gearing for alternate use. By turning this elbow-lever so that the outer end of its longer arm, D, is held in the button I, the large wheel G is thrown in gear with the pinion O, as the stud E on the short arm l) gets placed on the opposite side of the pivotpoint from the pinion. The double cog-Wheel G G is held on the stud E by means of a springkey, It, passed through a hole in the stud.

When it is desired to change from fast to slow motion the spring-key I6 is taken out and the double cog-Wheel drawn outward on the stud till the part G clears the pinion O. The elbow-lever D is then turned one-half a revolution until the end of its longer arm may be fastened in the button I, when the stud E will be between the pinion O and the pivot-point of the elbow-lever, so as to throw the smaller part G of the double cog-wheel in gear with the pinion, and thus cause a slow motion of the churn-dasher. The change from fast to slow motion, and vice versa, may be effected in an instant almost, whenever desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with a pinion, (J, of the pivoted elbow-lever D D with stud E, and the double cog-Wheel G G placed on said stud, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of November, 1874.

HORACE L. GORDON.
