ICE-CREAM FREEZER.

.srncxmca'rronrormm part of Letters Pat t No. 605,606, dated June 14, 1898.

' Application filed April 21, 1897.

Be it known that I, EDGAR O. HILL, a citizen of the United States, residing at Horse Cave, in the county of Hart and State of Kentucky, have invented certain new and use ful Improvements in Ice-Cream Freezers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain" new and useful imp'rovementsin ice-cream freezers.

My improvements relate to various featu res of construction and arrangement. Among them are a removable'cream vessel adapted to be secured to a non-removable ice-receptacle cover, so that 'access'm'ay be had to clean both it and the ice vessel, an ice-door in the head of the ice vessel adapted when open to protect the cream vessel from the drippings incident to inserting the'ice," a peculiar and efficient construction for adj listing the supporting-shaft relatively to 'itssupporting bracket and which also permits the ice vessel to come down and rest upon the base, and

to other details hereinafter described, and

particularly pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure 1 is avertical sectional View of my improved apparatus; Fig.- 2, a plan view thereof; Fig. 3, a horizontal sectional view on the line as 0c, looking'downwardly; Fig.4, an enlarged vertical section of a portion of the apparatus, and Fig. 5 adetail View of the yoke and supporting-sleeve.

The letter A designates a'base, and the letter'B a supporting-bracket secured to the base and having flanges O,which stand apart enough to receive between them the support-' ing-standard D, pivoted at E to the bracket and adapted to be held at different inclinations by a pin F, fittingeither of the series of holes G and held by a chain Hto prevent being lost. A stop G prevents the standard D from getting out from between the flanges when the standard is in its uppermost position. The standard has a shoulder'I, upon which rests a thimble J, secured tothe bottom of the ice vessel K and held by jam-nuts L.. This thimble is adapted to revolve upon the reduced portion M of the standard. A cup 0, as brass or some material not subject Serial No. 633,087. (Np model.)

to attack by the salt used with the ice, is screwed upon the thimble'J. This cup acts to make a tight joint with the tip Q, also of brass or some material adapted to withstand the action of salt and carried by a sleeve P, whose tight connection with the cream vessel R prevents leakage therefrom]. The upper end of the sleeve P is fitted to revolve on the hub of a yoke S, which yoke ismounted upon an angular portion T of the standard, so as to remain stationary and in connection 'with the lower yoke U suspended by the rods V and held 'from lateral displacement by loosely fitting over the sleeve 1. To each of these yokes are pivoted arms W and X. The arms W carry a beater Y,'and the arms X carry a scraperZ.

On the rods V are mounted springs a a and b b, respectively. The adjoining'en'dsof the springs a are secured to their rod V, so that the springs act to hold the beater Y against the action of the cream, as suggested in Fig. 3, the springs permitting the beater to yield to the current and force of the cream. The springs b at their adjoining ends arealso secured to their rod V, so that they will resist and yield to the scraper Z in the opposite direction, as also suggested in Fig. 3. The

beater is beveled at c'on the side against which the cream acts, so that it will yield away from the can and give a contracted outlet or passage for the current of cream .between the beater and can. On the other. 'hand, the scraper Z is beveled on the side away from the approaching cream, so that it will recede from the walls of the cream'vessel-and permit the icyparticles 'which'it removes from the vessel to freely escape through the inclined passage thus formed.

Referring to the upper end of the ice vessel, it will be seen that I havejprovided it with'a cover 6., secured to it in a stationary manner, and that the cream vessel is provided with an annular bead d, which fits upon a gasket g, carried by the cover 6. Thus a tight joint is made between the cream vessel and such cover. To secure the cream vessel in such position, I provide turn-buttons h, adapted to pass over inclined lugs z','projecting from the cream vessel. By swinging the buttons to one side the cream vessel canbe removed, the tip Q'separated from the cup 0,

and the interior devices permitted to come out with the cream vessel.

In order to aerate the cream, which has the effect of making a better product and of 1naking it lighter and not so compact, I provide a top j for the cream vessel, perforated, as shown at 7;, to admit the atmospheric air to pass into the cream. A bail Zadapts the top to be removed and replaced.

The ice vessel is provided at one side with a handle m and at the other, so as to balance it properly, with an ice-door 0, having clips q, hinged upon a rod 0', carried by the cover 0. Inclined surfaces 3 on the ice-door are engaged by turn-buttons 2", so as to hold the door closed. XVhen the door is opened for the insertion of ice, it stands as a guard to prevent the drippings from the ice from getting over on the cream vessel and the joint between it and the cover 6. A drip-plug u is provided at the bottom of the ice vessel. Thus it will be seen that in my freezer I have provided for removing the cream vessel for the purpose of cleaning it and of giving access to the interior of the ice vessel for the like purpose, also a peculiar arrangement of cream-beater at one side and scraper at the other, which automatically yield to the force of the cream, and that these devices are beveled or have beveled surfaces, so that as to the beater a tapering channel is presented between it and the wall of the vessel on the contact side of the beater, while as to the scraper the tapering space permits the escape of the dislodged icy particles, while the scraper will also yield to severer currents; also, that I am enabled to produce a superior product by reason of my perforated top,whieh permits of the aeration of the cream during the process of freezing. It will be observed also that the construction of the sleeve I, with its tip Q and the thimble J and its cup 0, permits the removal of the cream vessel. It will further be observed that I can fold my ice vessel down to and upon the base A for convenience in shipping and in placing the apparatus away when not in use. It will be understood, of course, that when the handle an is taken hold of the two vessels are revolved about the standing beater and scraper and the central standard.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. I11 an ice-cream freezer, the combination with a central standard,of an ice vessel having a thimble provided with a cup, a non-removable cover for said ice vessel, a cream vessel removably secured to said cover and having an interior beater and scraper and a sleeve having a tip removably fitted into said cup whereby a tight but severable joint is formed so that the cream vessel may be removed.

2. In an ice-cream freezer, the combination with a centrally-shouldered standard, of an ice Vessel. having a thimble mounted on the standard and upon its shoulder, a cream vessel removably secured to the cover of the ice vessel, a yoke on the upper end of the standard, a sleeve rotatably mounted in said yoke at one end and connected to the cream vessel at the other, a tight but separable joint between said thimble and sleeve between the two vessels, a lower yoke on the sleeve and a springcontrolled pivoted beater and scraper carried by said yoke.

3. In an icecream freezer, the combination with an ice vessel having a cover and turnbuttons, of a cream vessel removably fitted in said cover and having inclined lugs projecting from the cream vessel for said turnbuttons, and an annular body fitted upon a gasket carried by the cover.

4. In an ice-cream freezer, the combination with a base having a bracket provided with separate wings, of a standard pivoted in the bracket between the said wings,the win g having a series of perforations, and a pin to hold the standard in adjusted positions.

5. In an ice-cream freezer, the combination with a central standard, of an ice vessel having a thimble extending through it, and a cup on the thimble with a conical mouth, of a cream vessel a sleeve secured thereto and a tip on the sleeve having a conical end fitted to the cup, said central standard passing through said sleeve,'cup and thimblc, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
