CHURN.

Specification of Letters Patent.

Patented Jan. 4, 1910.

To all whom it may concernrV Be it known that we, JOHN E. TAYLOR and THOMAS G. TAYLOR, citizens of the United' States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Churns, of which the 'following is a specifica-tion.

This invention relates to churnsrand particularly to improvements in the gear-driven vertical dasher type whereby simplicity, strength and cheapness of construction, as well as smooth easy action are secured.

The invention is particularly directed toward the simplification of the parts and the reduction of their number and to the securing of a sanitary easily cleaned dasher.

The device will be described with reference to the accompanying drawings, wherem: f v

Figure 1 is a perspective view of the as sembled mechanism, the `cream holding' receptacle being omitted; Fig. 2 is a side elevation. partly sectional of the apparatus shown in Fig. 1, the cream holding receptacle being shown-in section; Fig. 3 is a vertical section on the center line of the fly wheel; Fig. 4 is -a section on the line 4-4 of Fig. 3; and Fig. 5 is a perspective View of the head casting of the'frame and the guide rod' brackets.

Like numerals refer to like out the drawings.

The device is supported on a base board 1 carrying lugs or brackets 2 to position the tub or bucket 3 (Fig. 2).. Rising from this base board are two standards or supports 4 as pipe threaded into flanges 5 attached to the vbase board by screws 6.

parts throughby the diagonals 7. The upper ends of the standards 4 are threadedfat 9 into a casting 8 which serves as the frame head, gear support and cross head guides. It comprises a horizontal member l0, having-two openings 11 and 12, and a vertical member 13 having forward projections 14 at its ends. Each projection 14 is provided with two bearings 15. equally spaced, the bearings in one projection being alined with those in the other. A handle 16 is fastened to casting 8 at a convenient point to enable the operator to steady the device. V

A spindle 17 is forced into the hole 11 and upon this spindle turns a large internelly toothed gear 18 having a crank 19 and handle 20. The hole l2 serves as a bearing for shaft 21 fast to which are. a small gear 22 and a. Hy wheel 23. The gear 22 meshes with internal gear18, so that iy wheel 23 is driven at increased speedA from gear 18. The gear ratio is preferably about three to one.

.The fly wheel 23 carries a pin 24 projecting from its Aface and provided with a roller 25runningfree in slot 26 formed in cross head yoke 27. This yoke carries two parallel guide rods 28 forced into holes 29 formed in thebody of the yoke. These rods slide freely in the bearings 15 and constrain the yoke to rectilinear motion as the'tly wheel revolves. Because of the roller 25 and the distance between bearings 15 measured on each guide rod, a very free smooth motion is secured. The use of two uide rods prevents wabbling of the cross ead yoke and interference between it and the combined fly and crank wheel. Between the twol guide rods is an opening 30 having a set'screw 3l,

ably held in 'a vertical position, so as to reciprocate longitudinally with the cross head vby which a rod 32 of spring steel is adjustj yoke. This rod 32 is the dasher rod. The b dasher is formed of two cross pieces 33, having suitable openings 34 and is retained upon the rod by nuts 35. i

By. the construction just described we se cure a churn that is at once light, strong, and sanitary. The double guide rod construction gives a simple, light mechanism that guides the cross head in a straight line and permits the attachment of vthe dasher rod-immediately to the cross head yoke in direct alinement both perpendicularly and horizontally with the guide rods and propelling roller, 'thereby preventing all tendency, to yank or cramp or wabble at each stroke as is the casewhere the dash rod is attached to an arm or anyl projection out of line with the roller on fly wheel. This is a very important part of the construction of our churn. The use of a spring steel dasher rod gives the necessary strength, combined with lightness and permits the da'sher to spring sidewise and accommodate itself to the but-ter as it forms. It will benoted that lthe dasher is light and strong,`easi1y and conveniently attached and detached, and

may be readily cleaned after detaching it j spring steel dasher rod; adjustable connecfroin the cross head. The handle to steady the device is also an attractive feature.

We are aware of the pat-ent to Hunt No.

Having thus described our invention; what we claim is r- 1. In combination with a creain-l'ioldingl receptacle, a base board adapted to support and position said receptacle; tubular traine standards mounted on the base board; a fraine head connecting the tubular standards; a hand grip carried by the traine head; bearings on -the frame head; a train of gears mounted in said bearings; a crank or driving said gears; a {1y-Wheel driven by said gears; a crank-pin on said iiy-Wheel; bearings for vertical rods formed integrally With the frame head; a plurality of rods sliding in said bea-rings; a cross head mount-- ed on said rods, and having a transverse slot engaged by the pin on the iiy-Wheel and a dasher, adjustably secured to the cross-heads.

2. In combination With a cream-holding receptacle, a base board adapted to support and position said receptacle; tubular frame standards mounted on the base board; a frame head connecting the tubular stand ards; a hand grip carried by the traine head; bearings on the frame head; a train of gears mounted in said bearings; a crank for driving said gears; a fly-Wheel driven by said gears; a Crank-pin on said tiva/heel; bearings for vertical rods formed integrally with the frame head; a plurality of rods sliding in said bearings; a cross head mounted on said rods, and having a transverse slot engaged by the pin on the lily-Wheel; a

tions between said rod and the cross head;

1' and dasher paddles carried by said rod.
