Vlmproverrlent` inlce Cream Freezers Patented May 36,1871.
Tocll whom it may concern:
useful Improvement` in .Ice-Cream Freezers;
is a full andV exact `description of the construction and mode of use of the same, refer- `and to the letters andQigures thereon, the
same `inakinga part of this specification.
` `on the line A B. l
` `tatou` l `ing mixture and the cream or other article` that is to be frozen, both of these vessels together by means dof a `crank or `suitably` attached driving-pulley. Also, the mode of readily withdrawing the liquefied part of the l gelation, together with the mode ofagitating ithe `cream by means of a falling dasher 4or the figures. y y The stand C supports the axles Dand E l onopposite sides offthe freezer, and one or tothe outer vessel or case I G H near the q gravity when charged with the freezingmix ing such as `to allowof a non-conducting airopeningextends also through theair-space J .of drawing off the liquefied freezing-mixture. :At `the top I there is an opening through `hold the required quantity of cream,and has NITE-n STATES ATENT Enron.

IMPROVEMENT iN lcs-eREAM FREEzERs.
Specification `forming part of Letters Patent No.` 115,361, dated M ay 30, 1871.
Be it knownthat I, MORITZ "RosENsTnIN, of Boston, in the county of Suffolk andState of Massachusetts, have invented a new and and I do hereby declarethat thefollowing ence being had to the accompanying drawing Figure I, vertical `section through the .cen-' ter of the freezer. Fig. II, horizontal section III, plan of 4the agi- My` improvement *relates toh the construction of the parts that contain the ice or freezbeing attached to eachother, and revolving' freezing-mixture during the process of constirrer. e
The letters referto similar parts in 'all of both axles may haveacrank, F, attached, or adriving-pulley. These axles are made fast center of lits length, so that its center of mof tiongmay nearly coincide with its center of ture and with cream. Within the outer case' thereis a smallervessel, K, made of wood or othernon-conducting substance, its size bespace, J, betweenthe two vessels. `At the bottom Hof the outer case G there is an aperture closed by the screw-cap U. This and the inner case K, and is for the purpose both cases, provided with a flange to receive a lip that is turnedfoutward on the top of the cream-.vessel M. `This vessel, usually made of tinned iron, may be either cylindrical or slightly tapered. It is of such capacity as to on its exterior, both at the Sidesand the bottom, wings or vanes T T, for the purpose of forming currents or eddies in `the freezingmixture when it is in a semi-fluid state. The agitator V is made of metal, and of such weightand size that it may moveback and' forth in the vessel M and equalize the temperature of the cream. It is provided with open spaces y y to facilitate its passage through the cream. There are three covers to the `cream-vessel M. The first, N, is of tinned iron or other metal; the second, O, is made of India rubber; and the third of metal,
slightly convex to. receive the end of the screw S, which passes through the horizontal bar Q, the ends of which are held by the Studs R R. y
" The'refrigerating mixtures are introducedV `at the top I. The vessel M filled with cream,
and also containing the dasher V, is then inserted; `the covers N, and I? putin place and fastened down by the screw S. The machine is `now turned rapidly. As it revolves the part V falls, at each half revolution, from one end to the other of the cream-vessel and equalizes the temperature, giving a smooth rconsistence to the cream. The side vanes T assist in agitating the freezing-mixture in the space L.
If it is desirable to draw off the liquefied portion of the freezing-mixture, or to add more salts, it may readily be ,done by removing the screw-cap U without disturbing the creamvessel.
What I claim, and desire to secure byLetters Patent, is 1. Arevolving refrigerating apparatus com- -bining an outer vessel, G, an air-space, J, a
non-conducting vessel, K, containing the freezingmixture, and a central vessel, M, for holding the cream, substantially as described.`
` 2. In combination with the three vessels, G K M, and the air-space J, the aperture through the double bottom H K, iitted with a yscrew-cap, U, for the purpose herein described.
3. The combination of the agitator V and the cream-vessel M, as described, and for the purpose specified.
