LOUIS, MISSOURI.

To oll'whom it may concern: -Be ltknown that I, JOHN R. GILDA, a citi- "zen of the UniteclStates of 'America. and a resident of the city ofSt. Louis, State of Missouri, have invented certain new and useful Improvements in Churns, of which the followingis a specifications The main'objects of this invention are to *provide an improved construction for hand operated. churns to provide improved mech- -,anism for operating a vertically re'ciprocatory dasher in churns of this type; to provide an improved lid construction for such churns whereby all of the operating mechanism will becarri'ed by the lid, and may be receptacle, and whereby the progress of the churning operation may be watched with-' out necessitating the removal of the lid.

These objects are accomplished by the device shown in the accompanying drawings, on which Figure 1 is afront elevation of a churn .const-ructed according to this invention, the 1'25 receptacle being in section and partly broken away, Fig. 2 is a side elevation of the lid of earthenware.

and the mechanism carried thereby, the outer gear being in sectlon and the dasher -being omitted. F 3 is a plan view of the Fig. 4L is a rear elevation of the slotted cross head which forms part of the dasher.

pitman mechanism.

In the construction shown 1n the drawings, the receptacle 1 open at the top and is of suit-able shape to permit it to be made The vertical walls of the receptacle 1 are offset outwardly adjacent .to the rim thereof, to provide an inner annular ledge 2 for receiving the circular glass plate 3, which forms a closurefor the receptacle. The outer surface of the walls is also provided with an annular shoulder 1 for. engaging. the securing lugs 5 and clamp screw 6 of a flanged metal cover 7 which fits over the rim of the receptacle to protect the'glass cover 3 and at the same time serve as a support for the operating mechanism. The outer cover 7 is provided withthree depending lugs 5 and'8, there beingtwo hook shaped lugs 5, one being directly behind and hidden by the other, in. Fig. 2. These hook shaped lugs and the screw 6 engage the shoulder 4 in such-manner as to rigidly secure the cover (in place. Sight openings 1 Specification of Letters Patent.

9 in the cover 7 enable the operator to watch the progress of the churning operation.

A dasher 10 of suitable form is carried by an upright rod 11, which extends through central apertures in the covers 3 and 7. The

upper end of the dasher rod 11 is connected with crank operated pitman mechanism, whereby it is reciprocated vertically.

The operating mechanism comprises a rotary member 12 in the form of a wheel having a heavy rim so that it acts as a fly wheeland having on one faceadjacent to its rim, ,aprojecting pin 13, carrying a roller 14;. A slotted bar or cross head 15 is fastened to the upper end of the rod 11 by means of a set' screw 16, and is slidably mounted upon a pair of vertically disposed stationary guide rods 17, the cross head being provided with four bearing lugs 18, which slidably fit the rods 17. The slot in the cross head 15 is engaged with the roller 14 in such manner that the rotation of the member 12 causes the dasher 10 to reciprocate vertically.

Instead of having the usual straight slot in the cross head 15, hvliich, as is well known, would produce a harmonic motion, the slot is a cam groove of special form, being off-set downwardly at its middle part, so that when the pin traverses the are which forms the lower part of its path, the dasher will be caused to make an additional up and down stroke of short amplitude, and its movement will thus consist of alternately long and short strokes, a motion which is found to produce highly eflicient results. It will be observed from Fig. 1 that the'pin occupies the outer horizontal portions of the slot in the crosshead 15 during those portions of-its cycle of movement during which the vertical component of its direction of motion is greater than the horizontal component, and traverses the offset portion of the slot in the cross head when its direction of motion is mainly horizontal. In this manner, the dasher is caused to move up and down rapidly at all times except at the instant when it-changes its direction of movement, and there are no'intervals, such as occur when the slot in the cross head is. a straight horizontal slot, during which the vertical movement of. the dasher is so slow that it is practically stationary. I

The member 12 is journaled on an axis which intersects the axis of the dasher rod 11, and which is at right angles to the plane i of movement 'of'the cross head 5 15. i The wheel 12 is carriedby a'shaft 19, which is journaled in an upright frame 20, rigidly mounted onthe top of the, outer metal-coverv 7. The upper part of the frame is provided with overhanging arms 21, to which the rods 17 are secured; A spring 22 is secured to the under face of the cover 7 in position-tobear on the glass plate 3 and prevent it from being lifted when the liquid .contents of the receptacle are dashed against 1 it. A metal eyelet 23; is secured in the aper. ture in the glass plate 3 to receive the dasher rod 11 so as to, prevent it chipping the plate. A pini0n24 is fixed on the shaft 19, and meshes with an internal gear 25, to which. the

crank 26 is secured. The gear servesas. a guard which prevents the possibility of the opera-t-ors clothing 5r handslbecoming entangled in the gearing. r

The operation of the device shown will be readily understood from the foregoing description. 1
