CHARLES A. BOONE, OE SHICKSHINN Y, PENNSYLVANIA.
Letters Patent No. 102,481, dated lifag/ 3, 1870.
IMPROVEMENT IN CHURNS.
The Schedule referred to in these Letters Patent and making part o the same.
Nature and Objects of the Invention.
My invention relates to the combination of a dasher, having a hollow shaft and hollow bottom paddles, with stationary perforated wings fastened to opposite sides of a churn in'such a manner as to oiifer resistance t0 the cream as it inclines to the motion of the paddles; the objects of theinvention being to bring air to the bottom of the churn, and. to convert the wings into dashers without expending power for these purposes; and to hasten the operation of churning.
Description of the Dra-wings.
Figure 1 is a vertical section of' a churn embodying my invention.
Figure 2 is a perspective view of the dashel'r.
Figure 3 is a vertical section of the dasher, showing the openings in the sha-ft and bottom paddles, through which air is introduced.
General Description.
A is the churn body.
Ihe shaft B has the opening d, and is provided with the paddles C and D.
The paddles C are fastened so as not to interfere with the openingrl; and the paddles D, having the openings c, are fastened so that the 'openings Vo connect with the opening d.
The escapes f of the paddles D are roamed out, andare two in number, placed near the end of the p paddles.
The shaft B has the beveled wheel .F at the top.
The upper journal of the shaft B works in the bearing G.
The lower journal works in the metal pit H in the bottom of the churn.
The perforated wings I are fastened to opposite sides of the churn body A.
The paddles D revolve beneath, and the paddles C above, the win gs I.
The paddles D are flared so as to press the cream toward the paddles C.
The paddles C are flared so as to press the cream toward the paddles D.
The wings I may be cut in two, and placed so as to leave a space between them, and another set of paddles, C, placed upon the shaft B, to revolve in the space between the wings I.
rIhe lid of the churn is made in two pieces, l and o.
The gearing, consisting of the drivingwheel M, bearings L L and G, and crank N, is fastened to the piece lof the lid.
The piece o has the hole n to admitthe air, and the guard p to prevent the cream from splashing out.
Motion is communicated to the dasher through the beveled-wheels l" and M.
The crank should be turned so that the thin edges' of the paddles C and D will go foremost.v
When the cream is poured into the churn it will rise in the hollow shaft/B of the dasher; but, hy rapidly rotating the dasher, a vacuum is caused by the bottom paddles D.
The cream first falls from the shaft into the vacuum; then the air enters lthe opening d near the top of the shaft and iills the vacumn as fast as itis created. rIhe airis, in this manner, introduced into the bottom of the churn, and is distributed through the cream, thus hastening the operation of churning.
The wings I resist the cream as it iuelines to the motion of the paddles, and as it strikes the wings it is beaten and broken by being forced through the perforations.
By this mechanism, power is not expended, especially to bring the air tothe bottom of the churn, nor to convert the wings I into dashers.
Claim.
I lclaim as my invention- The dasher, having the hollow shaft B, hollow paddlesD, and paddles C, in combination with the stationary perforated wings I, substantially as and for the purpose hereinbefore specified.
In testimony that I claim the foregoing improvementin churns as above described, I- have hereunto set my hand and seal, this 23d day of March, 1870.
