CIEIURN II'JASHER.`

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, PETER VAN ANTWERP, of Coeymans, county of Albany, State of New York, have invented a new and useful Improvement in Dashers of Churns, which I denominate Van Antwerp s Reacting Churn-Dasher, of which the following is a full and accurate description, reference being had to the accompanying drawing, making part of this specification.

A A' is the Vertical rod or handle of the common churn or hand dasher which may be of any required height. About three inches more or less (according to the size of the dasher) of its lower end is of an enlarged diameter forming a kind of cylindrical knob, shown at A' in the drawing, around which I arrange two series of radial buckets or paddles B B', one series being placed over the other, for the purpose of agitating the cream. These paddles resemble in construction the oars employed for propelling boats, being broad and flattened at their outer ends where they project into the cream, tapering from thence to their inner ends, where they are adapted to openings in the cylindrical knob A' hereafter described. The manner of arranging these paddles is as follows: Around the knob A' and at equal distances from its upper end I make a series of holes extending from the surface to the center of said knob intersecting a hole which I bore in said center, the number of these holes depending on the number of paddles employed. These openings are made in a direction inward and upward so that when the paddles B are in place their outer ends are depressed as shown in the drawing in-' stead of standing out at right angles with the axis of the cylinder A'. I make the same number of openings also around the cylindrical knob A' near its lower end, at equal clistances from this end and adapt to them the paddles B'. These are not placed immediately below the holes in the upper series but are arranged below the spaces intervening between each of the upper apertures or paddles in such a manner that a perpendicular let fall .from each of the upper holes would pass through the spaces intervening between each of the lower ones. These lower apertures are made in a reverse direction to the former ones, viz, inward and downward to the opening made in the center of the cylindrical knob A' so that the outer ends of the paddles adapted to these openings are 2,957, dated February 16, 1843.

when in place elevated to the level of the outer ends of the upper paddles, as shown in the drawings, where owing to the oblique direction ofthe openings in which the paddles B B' are inserted the outer ends of the paddles B are represented as depressed and the outer ends of paddles B' elevated to the the left edge of the paddle in the manner Specified. The paddles B' are also inserted r obliquely in their apertures-that is, with the upper face or surface of each turned obliquely upward but in a differentdirection as represented in the drawing where the upper face of each of the' lower paddles B' is turned obliquely toward the left elevating the right edge of the paddle at about an V angle of 45 above the other one.

This mode of constructing the dasher gives it great advantage over the ordinaryQ churn dasher as by the employment of paddles arranged in the manner stated no vacuum is created interfering with the operation of the churn, consequently there is no mingling of air with the cream to obstruct the gathering of the butter; owing to the manner in which the paddles are arranged a reaction is also produced in the cream as it is impelled in' one direction by the paddles B in the upper series and in the opposite direction by the paddles B' in the lower series.

The hole in the center'of the cylinder A' -may be filled, after the paddles are in place, with cement or putty and its end closed by a piece of cork or other elastic substance projecting a suflicient distance below the end of the cylinder A' to touch the bottom of the churn when the dasher is used diminishing by its elasticity the force of the stroke given by the dasher to the bottom of the churn preventing it by this means from being bruised.

' The dasher so constructed is operated like the common hand dasher and is to be employed in the ordinary Vertical churn in the same manner that the common hand dasher the dasher, the series of paddles B B' armode of constructing the dashers of churns,

used. ranged above each other* as described and Having described my mprovement in the operating, in the manner set forth.

PETER`VAN ANTWERP.

What I claim as my invention and desire to Witnesses: secure by Letters Patent s ABRAHAM VERPLANK,

Combning With the rod or stem A, A' of HANZ TEFFT.
