Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed March 14, 1910. Serial No. 549,081.

To all whom it may concern:

Be it known that we, ALVIN H. W'ILEY, Dian W'. LATI-inn, and MARIAND W. LATI-rmt, citizens of the United States, residing at Linden, in the county of Cass and State of Texas, have invented certain new and useful Improvements in Uhuru-Operating Mechanism; and we do 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.

Our invention relates to churn operating mechanism.

The object of the invention is the provision of a simple and inexpensive mechanism which may be readily attached to a wall or other suitable support and easily manipulated to reciprocate the churn dasher.

A further object of the invention is the provision of means for normally raising the plunger operating mechanism, whereby the device is more easily operated.

With the foregoing and other objects in view, the invention consists of certain novel fea-tures of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of the device shown attached to a wall, Fig. 2 is a front elevation of the same; Fig. 3 is a detail sectional view on the line 3h?) of Fig. 1.

Referring more especially to the drawing, 1 represents the wall or other suitable support, upon which at the proper height is secured a bracket 2 by bolts or other fastening devices 3. Adjustably secured to the front face of the bracket 2 is a girder 4 at the lower end of which is mounted a guiding arm 5 adapted to receive a guiding rod 6. This guiding rod is threaded upon its lower end, as at 7, to receive the adjusting nuts 8 which hold the rod in proper adjusted position and has its upper end bent at right angles, as at 9, so as to pass through the slot 10 in the girder 4. The end 9 is threaded to receive the nuts 11 so that this end may be secured adjustably within the slot and which serve also to regulate the distance of the upper end of the rod from the upright 4. Slidably mounted upon this rod is a coupling block 12, which is connected to the end 9 of the rod by a spiral spring 13 which surrounds the rod and normally tends to raise the block, as will hereinafter be described.

.Journaled in the upper end of the up right 4, is a crank shaft 14 having a pulley 15 on one side and a crank arm 16 on the opposite side, the latter to be engaged with a pitman 18 which is pivotally connected to the block 12. The crank shaft receives its power from the pulley 15 which is connected by a belt 19 to a guiding hand wheel 20 journaled adjacent to the lower end of the upright 4.

The churn is shown at 21, its dasher 22 in dotted lilies and the connection between the dasher and the connecting block indicated at 23. This connection is pivoted at its upper end to the block 12 and reciprocates through an aperture in the outer end of the arm 5, as the block 12 moves over the rod 6 under the impetus of the pitman 18.

The churn is held stationary on the floor or other support by means of blocks 24.

When the hand wheel 20 is revolved, the shaft 14 is also revolved through the connection of the belt 19 with the pulley 15 and thus the pitman 18 and the block 12 are reciprocated. The spring 13 is eX- tended when the connecting block 12 is lowered and exerts its influence to raise the block after the crank has passed its low dead center. This action overcomes the weight of the parts and makes the operation comparatively smooth and without undue exertion.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.

Having thus described our invention, what we claim is:

1. A churn operating mechanism comprising a supporting bracket, an upright mounted thereon, having an adjusting slot therein, a guiding rod adjustahly mounted upon said upright and extending into said slot, churn and operating pitrnen, a connecting block joining said pitmen and slidably mounted upon said guiding rod, a resilient connection between the upright and the connecting block, and means connected to the operating pitman for reciprocating the connecting block and the churn pitman.

2. In a churn operating mechanism, the combination with a supporting bracket, of an upright secured thereto having a slot therein, a guiding rod having its upper end bent at right angles and adjustably mounted in said slot, an apertured arm secured to the upright and adapted to receive the lower end of said guiding rod, a. coupling` block slidably mounted upon said rod, a connection between the upper end of said rod and
