To all whom it myconcem.-

.Be it known that I, EDWIN L. DRAM, a citizen 0f the United Stems residing at Winchester, in the eountyof Franklin and State ot Tennessee, have invented certain new and.

useful Improvements in Ice-Cream Freezers;

and I-dohereby declare the following -to be-a frh-clear, andexaet description of the inv entlon, such as willenable others skilled in panying drawings, and to the letters of refer-j the artto which it appertains to make and use the same, reference being hadv to the accom@ 'ence marked ;hereon, which form a part of this Y s'peceation.

" -Thisinvention relates A to'devices for ing cream with .the usualrefrigerant, the ob ject being, teeconomize'iee in the operation and to cause the cream to be firmly frozen in a cake to the'fnllest extent ef'capacity of the vrefrigerant and to remove it for the purpose of' servingat any desired time after the freez ing process begins orof storing the cream in a frozen state, vif desired, the' details of construction necessary to which en d are'herein- 'after fullydescribed, and the parts claimed as new pointed out in thc'claims.

In the accompanying drawings, Figure 1 is an interior viewof the deveefromfthe side tional plan view showing` a portion of the ner of hanging it in the position shown'in Fig.

opposite the crank, showing the parts inv their proper relative lpositionswhen freezing, the

side'of the easing being' removed for the pur'- pose of showing'sueh parts. Fig. 2 isa seccream-containin g pan andexhibiting theinan- 1. Fig. 3 is a side elevation of the device from the side opposite that shown inrF-ig. 1-,

showing thehand -crauk and sho-wing' by dotted lines the relative positions ofthe parts.. Fig. 4 is'- a sectional perspective view of a por- 'tiony of the casing showing the small; casting employed in sustaining the'pan'in'its operativ'e position. Fig; 5 isa'sectionalside elevation of a portion of the refrigerating-eylin der, showing the hollow journal and its flanges.

Fig'. 6 iF a section on linee: 0:, lig.` 5, 'further exhibiting the parts there'inshown. Fig. 7 is' a side elevation vofthe device, showing a form of gearing for 'driving the cylinder. In the figures like reference-marks indicating corresponding parts inthe several views,

"A is the casing, whiehis composed of-two parts, a bottom o andtop-af, which may he'v i I secured iu place when closedin any approved manner,and maygif desired,`be hinged to.- 55

gether admitting of 'the raising 'of' the top a to aord an entrance to the interior for vari- -eus purposes. This casing is made of any suitable noneonductingmaterial, the cleats on its bottom performing the double function- 6o of preventing warping and of legs on which Pto set' the' machine.- In the preferable con struction the lower parte! this easing A is` provided en two of its interior sides with pro 1 outwardly-projecting ilanges, which rest on said pins and support the pan at such a distance below the cylinder that the milk or otherT Afluid contained therein can all-beaecu'mnflated on the-vzsylinder, having the eectto eu- 7e large its, diameter, thus reaching'to th'ebot-1 tom ofthe pan. The flanges on the pan are f, also provided with gaps in their continuity,l

Jectinig pins,wh ile the pan B is' provided with 65,-

so placed that when these notches are brought in conjunction with the pins in the sides of 75 the -casing the pan with its contents will drop' t clear of contact with the cylinder, thus enabling the operator at any time in the'process;

of `freezing to obtain frozen creamffrom the cylinder unmixed with that Vyet fluid in the 8o pan. The freezing can be resumed by replac` ving the pan on its supports', bringsthe contents in contact with"th"e"xfe-U4 frigerating-surface of the cylinder. i

'r boxes in the top, edges of the part ao'f the casing and is so set as to run to the desired depth Vin the pan B.- yThis cylinder is adapted to hold the refrigerant compound, and has onf f one. end a Yjournal c, while/` the other end is gc vprovided with aV hollow neck for thepassage of the refrigerant Vto the interior,whichneck .c also performs the functions of a bearingv yfor that end of thecylinder; |The'holl'ovv neck c is provided with annular flanges e295 which form'the bearing inthe boxand pre` vent outward orjinward movement. This hollow neck may be stopped iny any-approved manner. This cylinder may be provided with The. cylinder C runs4 in any suitable notches; 85

longitudinal agitating-'slats lon its inner eirroo ou inference, if desired; but-this is not a point of novelty in its construction. v

If desired, the journal c is provided with a. spur-gear c, while attached to the casing in an approved manner is the pinion c", engaging therewith and being provided with a crank of the desired length. If desired, a motor of any suitable form may be attached to the cylinder by belt or otherwise, or a band-pulley may bc applied for a large manufacturing machine. t

In the side of the 'casing toward which the cylinder C runs is a pan or receiver D, which is for the purpose of receiving and storing under refrigeration the cream a when it is removed from the cylinder by means of the knife-edge d, which is securedto or made integrally with the said pan D, and is s`o formed and arranged as to scrape the surface of ythe cylinder C when heid against the said cylinder as itis revolved by means of the handle d or screw d2 which are supplied for that purpose. As soon as filled or the desired amount is obtained within this pan D it may be removed and the cream placed therefrom in dishes for serving, any residue being left in the pan, which is then returned to the refrigerating chamber, where it is preserved frozen until needed.l This pan D may be hung on trunnions after the manner of the pan B on the cleatsa, if desired; but the construction shown and at the present time the preferred Y oneis as shown in Fig. 1, where it is placed on.

vthe bottom of the casing'A. v y

The operation of this device-is as follows: The refrigerating compound or mixture is placed inthe cylinder C and the cream tobe` frozen in the pan B, after which-the cylinder. l is revolved in the milk, which it takes up,=

and which freezes on its surface, the accre.l tion continuing' to the desired depth, after which the knife-edge d of the pan D is pressed against the periphery of the cream covered cylinder, the pan B lowered from its place, so that no un'frozen cream can be taken up, and as much cream as desired removed from the Y' cylinder.

l stantially as described. f

and frozen upon the cylinder may be removed from the same and discharged into the storage receptacle and stored or removed from the casing therein, substantially as described.

2. In an ice cream freezer the combination with the close inclosing casing, of arevoluble cylinder for holding a refrigerant material, a removable receptacle for the material to be frozen, a removable storage receptacle for frozen material separate from the casing and supply receptacle, the two being independently removable from the casing and a knife movable toward and from said cylinder whereby the material taken from the supply receptacle, and frozen on said cylinder, may be removed from the cylinder and discharged into scraper, said storage receptacle being movable rl toward and from the said cylinder independ" ently from the supply appliances, and-independently removable `from the 4. In an ice cream freezer the combination with the casing A, of the vcylinder C, adapted to revolve therein, the pan D having the cutting edge d and' means for suppl-ying cream to the said cylinder, substantially as shown and specified.

5. In an ice cream freezer the casing A and the cylinder adapted to revolvethereimthe pan D having -the cutting edge, means for supplying cream to the said cylinderand casing, aub-l means for moving said pan D extending outside of the casing, substantiallyas described. 6. In an ice cream freezer the combination from its interiorsides of a pan having notched IDO with the casing providedv with pins projecting flanges supported by said pins, and 'the cylinder for holding the refrigerantl material,

substantially as described.V

-7. In van ice cream .freezer the casing-A., cylinderpC, receiver D, having edge d andthe screw d"v substantially as described.
