IMPROVEMENT IN CHURNS.

The Schedule referred to in theseV Letters Patent and making part of the same.

T o all whom it may concern:

Be it known that I, ROBERT D. Ozuns, of'Lena, in the county of Stephenson, and State of Illinois, have invented certain new and useful vImprovements in Ohurns, of which the following is a full, clear, and exact description.

My invention relates to that class of churns having vertical flashers, which are revolved in opposite directions; and

The improvements herein claimed consist- First, in mount-ing the driving-,wheel for imparting motion to the dasher-pinions ou an arm projecting from a frame or casing surrounding the upper portion of the flasher-shafts and secured upon the churn-top, as hereinafter described.

Second, in combining, with the dasher-l'lnions, mounted on independent dasher-shafts, a flaming or casing, provided with shields or boxes partially enclosing the pinions, and admitting of the pinions being slipped in place upon their respective shafts sidewise, as hereinafter described, thus rendering unnecessary the removal of the casing to detach the dashers.

Third, in combining with the casing which partially enoloses the mechanism, two concentric dashervshaft-s, rotating inoppositedirections, in such manner 'that bot-h shafts are supported by the bearing of the upper pinion, as hereinafter set forth.

In the accompanying drawingsl* igure 1 represents a vertical central section through my improved churn Figure 2,- a side view, at a right angle to fig. 1, of that portion of the churn which is secured upon the top; and

Figure 3, a top View of the upper pinion-box or shield.

A represents a churn-body or tub, upon which fits a flanged top, B, having a hole through the 4centre for the passage of a tubular shaft, C, and an inner shaft, D, the former secured by screws to a cross arm or piece, c, having downwardly-projecting arms, c', to form a slatted dashcr, 'and the latter shaft passing through the cross-piece c, and, in this instance, enlarged to form a shoulder, d, on which the crosspiece c rests.

The shaft D has secured upon its lower end an arm, d1, the slats d* of which project upwardly between those, c', of the other dasher.

Uponthe upper end of shaft D is keyed a bevelpinion, E, and a like pinion, F, is secured upon the upper end of the tubular shaft C. The pinion E is in this instance secured upon itsshaft by a pin which passes through the "centrally-projeoting or raised top ofthe pinion and through the shaft.

A hollow frame or casing, G, surrounds the shafts D and C above the top B.

This casing is provided at the top with an open-4 sided shield or box, H, for protect-ing the pinion E, which rests upon the central projection 71, in the box.

The key for securing the pinion to its shaft is passed through an opening, h', in the top of this box, and the pinion is slipped in place through the open side ofthe shield.

A shield, I, having likewise, an open side, snrrounds the lower pinion, and terminates in a ilanged rest or support, J, which is screwed to the top B, and secures the casing in place.

The pinion F is shown in this instance as kept from moving vertically bythe boxing I and top of the support J, and it will be scen that both the shafts, (l and D are held up by the pin which secures the pinion E in place, and that by removing this pin, the shafts and their dashcrs can be rcadil y detached from the casing and top, and the pinions slipped out of their shields sidewise.

An arm or shaft, K, projecting from the casing G,

midway between the pinions, has secured upon it a bevel-wheel, L, provided with a crank-pin, l, for driving the pinions, and, consequently, their shafts and the dasllcrs, in opposite directions.

By this mode of mounting the driving-wheel, I dispense with the support lor frame for the driving-wheel secured upon the edge of the top or to the side of the churn heretofore employed.

The pinion-shields, it will be observed, both serve to pro`tect the pinions and to strengthen the casing G, and the lower part of the casing, or the rsupport J, serves both as a lirni rest for the casing, and as a cover to keep dust and dirt from enteringthe hole in the churn-top. V

`What I claim as my invention, and desire to secure by Letters Patent, is

1. The arrangemeut,^as set forth, of the concentric dasher-shafts, the casing, the driving-pinions, and the interposed driving-wheel mounted on an arm project ing from the casinfr.

2. The arrangement of the concentric dasher-shafts, their pinions, and the open-sided pinion-boxes, all constructed as set forth, for joint ope ation.

3. rllhe combination of the concentric dasher-shafts rota-ting in opposite directions, the casing and the pinion E, from which both shafts are suspended, al1 these parts being constructed as setv forth for joint operation.

I testimony whereof, I have hereunto subscribed my naine.
