ICE-CREAM Specicaton of Letters Patent No.

To all 'whom it may concern:

Be it known that I, E. I). ToRnEY, of J ersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Ice-Cream Freezer; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, represents a vertical central section of an ice cream freezer constructed according to my invention. Fig. 2, is a horizontal section of the same.

Similar letters of reference indicate correspending parts in the two figures.

To enable others skilled in the art to make and use my invention, I will proceed to describe it.

A, is a can made of tin, sheet metal, or other suitable material in a cylindrical form, and its bottom B, is provided with a socket a, which forms the step for the stem C, of the beater D, and the cover E, of the can is strengthened in the center by a boss through which the stem C, of the beater passes freely, as clearly represented in Fig. l, and the socket a, together with the boss b, form the bearings for the stem of the beater. The beater is constructed on one side of a series of slats c, perfectly smooth and placed in the beater frame el, in a position which is inclined from the outside toward the center, and the other side of the beater contains a scraper E, which works up close enoughto the sides of the can to keep them free from ice but not so close as to cause the beater to bind, and I lind that a rigid scraper will all the yielding scrapers, as the forlner in no case gives a chance to the cream to adhere to the sides of the can to form ice there.

The form of my scraper is clearly represented in Fig. 2, and it may be constructed of wood or metal, but I prefer making it of wood, as a. wooden scraper does not injure the sides of the can when it comes in contact with them, and yet it performs its duty, viz: to peep the sides clear of ice just as perfectly as a metal scraper could do it.

The bottom of the can is provided with legs or projections c, which fit over a cross bar F, which is rigidly attached to the bottom of the barrel or pail G, which surrounds the can and this cross bar is provided in its center with a cavity f, which receives that FREEZER.

part of the bottom B, of the can which forms the socket a, for the stem C, of the beater.

By this means the cross bar F, serves to keep the can in the middle of the barrel, and at the same time the legs e, as they come in contact with the sides of the cross bar F, prevent the can from turning, and also serve to keep the can erect when the beater is operated. The stem C, of the beater passes freely through an opening L, in the cover H, of the barrel or pail, which is placed on loosely and-which requires no extra fastenings as the stem of the beater is guided in such a manner in the can A, that the cover H, is relieved of all pressure; and the steln C, extends beyond the cover H, and it ends in a square part to which the crank I, is attached.

The operation is as follows:-The cream is poured in the can A, and its cover E, is placed on firmly and the can is placed in the barrel G, the socket a, being inserted into the cavity f, in the cross bar F, and two of the legs c, being placed close up to the sides of this cross bar, as clearly represented in Fig. l. The freezing mixture is now packed into the barrel G, around the can A, in the usual manner. The cover H, may or may not be placed on the barrel G, but it is desirable to have it on, as the action of the' freezing mixture on the cream in the can is more uniform, and quicker if the cover is on than when the same is off and the beater is now rotated by means of the crank I.

As fast as the cream is thrown upon the sides of the can, it is cut off or removed by the action of the scraper E, and then beaten and lifted and again spread over the surface of the can, to be further cooled. The greater the ext-ent of freezing surface over which the cream can be spread, and the more thorough the beating which it receives, the quicker will the operation be concluded and the better will be the quality of the icecream.

The slats (c), by being inclined, lift the cream upward and so spread it over the entire surface of the can, and at the same time thoroughly beat it. The dasher E, by being rigid, thoroughly removes the cream from the sides of the can, and thus rapidly presents a` clean and therefore active refrigerating surface for the reception of the cream.

For economy of time and ice, it is of the first importance that the scraper should thoroughl clean the sides of the can. If a coating o cream be left thereon, it is comparatively as difficult to freeze the cream as it is to raise steam in a boiler Whose interior surface is coated With scale.7

I do not claim the employment of a beater having straight slats; nor do I claim the use of an'elastic or yielding scraper. But

Having described my invention, I Claim as new and desire to secure by Letters Patent:

l. The arrangement and Combination, Within the freezing vessel, of the rigid scraper E, and the inclined beating slats
