6 My. Rowntree's Patent Butter Churn.(Jan.

Tt is well known that milk is a mixture or compound of 01), Iymwph, Serum and Salt; the Separation of which produces but- ter, cheese, and whey. The Serous and oleaginBous parts Se- parate after Standing Some time, and rise to the top in the Form of cream. From this cream, put into a churn, butter is produced, by the agitation and Separation of its parts. The Machine which I have invented for this purpose, and which T call my agitating and separating Machine for making but- ter, and for other purposes, wbere agitation or Separation 1s required, 1s represented in the annexed Drawings. It con- zists of a tube, or tubes, Either bent or Straight, for the re- ception of the cream, but open at both ends; and, in which are inserted, breakers, with two caps at their outer extremi- ties, made in zuch a manner as to fit closely to each end of the tube; or these caps may be loose, and fitted on or taken off at pleasure, as occasIOn May require.=-Figure 1 repre- Sents an outside view of the Machine as fixed to ils frame NN, and hanging on its axis or centres. Figure 2 reprezents a Section of the Machine, in which AAAA 15 an open beut tube, with the breakers BBBB out of the tube. CC arc the two Caps convected with the Breakers, and wbich are S0 con- tived as to ft closely to the two evds of the tube. DD are two Cross-bars, placed on the outside of wie Caps, and made to press against them by Screws or wedges; or in any other manner 50 as to prevent the cream from running out during we time of working or agitating the machine. Figure 3 18 a Section vf tbe Machine, with he Breakers BBBB within- Side. CC are the two Caps. DD are the Cross-bars, with their Screws, as fixed for work. Figure 4 represents a Sec- won of a straight tube, witb the Same apparatus as before de- Scribed in Figure 3, and Shewing its axis or centres EE, on which the machine 1s Suspended, and moved backwärds and jorwards. EF is a Small opening in the upper part of.the wbe. Pigure 2 and 3, wherein to pour tbe cream; or, Ifit be thougbt preferable, the cream may be poured in at one end of tbe wbe, while the other is closed. G- I5 a Vent-peg. H is an Evd View of one of the Breakers. 1 is an End View of the tube, or cylinder, containing the Breakers. XK is an End Viewotf one of the Caps; and L1s a Front View ol the Cross-bar, with its Screw, pressing against the Cap. M is be Handle, Lever, or Pendulum, ſor giving motion to the Machine, Such as is usual in other.machbinery; to whicb is afixed,-a moveable Sliding Weight, O, for 1he purpose of adjusting or balancing tbe weight of cream in the tube, 50 as to produce an equilibrium in tbe machine, whether the quan- Lily ol Ihe cream be Small or gieal.
