OPERATING MECHANISM FOR UHURNVS} I Patented Jan, 24, 1888.

I UN TE STATES PATENT OFFICE,

WILLrAMomMEs PATTERSON, or CLAYSVILLE, PENNSYLVANIA.

OPERATING MECHANISM FOR CHURNS.'

SPECIFICATION forming part of Letters Patent No. 376,752, dated January 24, 188t l Application filed March 16, 1887. Serial N 231,136. (No model.)

churn the dasher rod of which may be easily I operated, and which shall be automatically churn-body by screws 0 a, so as to permit the V and quickly raised after it has been depressed by the person using the churn.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described'and claimed.

In order that myinvention may be fully understood, I proceed to describe itwith reference to the accompanying drawing, in which the figure illustrates a perspective view of a J churn-barrel. with my improvements applied thereto.

In the said drawing, designatesthe body or barrel of the churn, said body being placed in vertical position, as shown.

b b designate two open uprights, which are secured at their lower ends to the sides of'the ready attachment and removal of the standards. The standards b b are braced together at their upper ends by 'a crossbar, (I, one end of which extends outward beyond the contiguous upright b, and is curved downward, as

shown at d.

e designates the dasher rod, the upper end of whichis attached by a pivot, e, to the oper-.

ating-leverf. The operating-leverfis pivoted atf to the lower end of a link, theupper end of which is in turn pivoted at g to the lower extremity of the curved end d of the cross-bar d. The leverf extends outward beyondtheupright b, and carries at its free ex- I tremity a pendent bar, h, which is pivoted at its upper end to the outer end of lever' f, as

shown at h. The operating-lever) is sustained normally in horizontal position by two spiral springs, t t, which are secured at their upper ends to the crossbar d at'opposite.

sides. of the upright b, and at their lower ends to correspondingpoints on the lever f, so that l one spring lies between the uprights b b and the other between the upright b and the curved portion at, of the cross-bar d. A handle, h, is

formed upon or suitably secured to the lower end of the bar h, so as to be conveniently grasped by the operators hand.

From the above description it will be seen that by pulling upon the bar h the leverf will be quickly depressed and impart a forcible downward movement to the dasher-rod e, and

that assoon as the lever f 'is released-feomthe pull the two springs it will draw the leverf upward with much force The two springs it are so placed as to render the movements of the lever f very rapid and steady and relieve the fulcrum f of the operating-lever from strain. 4

The entire device is simple and durable in constructiomandmay be. readily applied to and removed from the ohurn-body.

I claim as new and desire to secure by ters Patent,

net-

The combination, with the uprights'b b and the cross-bar d, having the curved end d, f

of the operating-lever f, connected to the curved portion d by thelink g, and the springs t 2", arranged as described, for sustaining and retracting the operatinglever, substantially as set forth. a In testimony whereof I affix my presenceof twowitnesses.
