HENRY S. POTTER, OF HAWLEY, PENNSYLVANIA.

IMPROVEMENT IN CHURN-DASHERS.

Specification formingl part of Letters Patent No. 120,097, dated October 17, 1871.

To all whom it may concern:

Be it known that I, HENRY S. POTTER, of Hawley, in the county of Vayne and State of Pennsylvania, have invented a new and valuable Improvement in Ghurn-Dashers; and I do herebydeclare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a side view of my invention. Fig. 2 is a top view. Figs. 3, 4, 5, 6, 7, 8, 9, 10, ll, 12 are detail views.

This invention has relation to churn-dashers; and the novelty consists in the peculiar construction and arrangement of the paddles, as hereinafter described; the object being to provide a churn-dasher having' a large number of separate paddles, which may be easily constructed, and adapted to their proper positions, as Well as removed for the purpose of cleaning them, and which will present the greatest surface possible to the cream without impedin g its necessary agitation.

Referring to the accompanying drawing, A represents the dasher-shaft of a plungedasher, upon the lower end of which are placed the paddles which agitate the cream. The shaft A is rounded, and from its lower end to a point Slightly above the positions of the highest paddle, is beveled to a protruding edge or tlange, a. The lower end is formed with a rounded tenon to hold the lowest paddle, which is marked b. The paddles, of which any desirable number may be employed, consists of wooden slats, having an elongated slot, al, in each end, and a rounded shoulder, c2, on one side or face. They fit on the shaft one over the other, a hole A being cut in each, excepting the lowest, marked b, of a form corresponding to the beveled part of the shaft. These paddles are designed to protrude from the shaft in various directions, as shown in the drawing; hence the holes cut in them, although similar in shape, are arranged variously, as indicated by the angular part, which iits the angle of the shaft.

In the drawing I have shown eight paddles,

which I arrange in the following relative order. The iirst or lowest, b, occupies the position already explained, its plane horizontal face being upturned. Upon this I place second paddle bl at right angles to it, its plane face down, and

shoulder c1 up. I next arrange the third paddle, marked b2, its shoulder al down, at an angle of forty-five degrees to the second, and then place on the third, a fourth paddle, b3, at right angles to it. The liith paddle b4 comes next in order, and is arranged exactly parallel to the first. lt is followed by b5, b, &c., parallel, respectively, to b1 b2 b2.

Every pair of contiguous paddles at right angles one to the other, should lie with their plane faces in contact, so that their shoulders al shall separate the oblique paddles, and thus compensate for the difference of space between the points ci.

The object of the above-described arrangement of. the paddles is to obtain a great amount of surface with which to beat the cream, and to leave the vertical channels created by the spaces a entirely free from obstructions, so that the cream may rush through and have a side slush between the beating-arms c2.

The paddles are constructed with abrupt vertical edges, the arms a2 being four-sided, and also blunt or square-ended, so as to better adapt them` to the performance of their function.

At the locality of the uppermost paddle on the shaft A a recess, a4, is cut, which renders the shaft round at that point, with a shoulder, a5, above. When the paddle 1')T is placed on t-he shaft it is turned around slightly at the recess af, and thus serves to lock all the paddles together.

For the purpose of cleaning them all the paddles may be readily removed. At first they lit the shaft somewhat freely, but after a time become swollen by the cream and tightened rigidly in place.

I claim as my inventionl.
