Application filed May 25, 1908. Serial No. 434,941.

" out, have invented a new and useful Im- .provement in Ice-Cream Freezers; and we do hereby declare the following, when takenin connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawingsconstltute part of thls specification, and

- represent, in' I Figure 1 a perspective view of a freezer constructed in accordance with our invention. Fig; 2 an end View of the rear of the,

This invention relates to an improvement in ice cream freezers, and while adapted for large sizes, is especially designed for small freezers for domestic use. In the manufacture of ice cream for domestic use it is frequently desirable to make cream of two flavors, the foundation being the same for both, the flavoring being put in just as the cream is ready to be frozen.

i The object of this invention is to provide a freezer having'two independent chambers or cells, which are connected and adapted to be turnedby a single crank; and the-invention'c'onsists in the construction and arrangement of parts as will be hereinafter described and particularly recited in the claims. I

In carrying out our invention as herein shown, the ice case or tub is of box-like character'comprising sides 2, 3, formed from a single piece of metal bent intoU-shape and secured to ends 4, 5 wlnch are connected to a bottom 6, and at the bottom the ends 4, 5, are also connected by guardstrips or flanges 7, forming a drip pan. In the end 4 is a deep notch 8 and in the end 5 is a slot 9,

while in the sides are one or more longitudinal slots 10 in a plane slightly below the bottom of the notch 8 and slot 9. Pivoted to the end 4 is a latch 11 having a bearing notch 12, and secured to the outer face of the end 5 is a latch 13 having a locking notch 14. The cans or containers 15 and 16 are cylindrical, \vith rounding ends so as to avoid corners which tend not only to the more ready removal of the contents, but permits the cans to be more perfectly cleaned.

.it the inner end, the can 15 is provided with a collar 17 having a locking notch 18, while the can 16 has a collar 19 into the edge of which the collar 17 extends, the collar 19 .of a sizeto closely it the outer end of the spindle 22 which carries a blade or dasher 27. The mouth of the can 16 is closed by a cap 28 like the cap 25, and having a sleeve 29 7 which is of sufiicient length to enter the slot 9 in the bottom of which it rests, and through which sleeve the spindle 24. extends, this spindle carrying a blade or dasher 30, and at its outer end has a square projection 31- with which the locking notch 14- of the latch 13 engages whereby the spindle held against rotation. Secured to the sleeve 26 of the cap is a pinion 32 which meshes with apinion mounted on the outer face of the end 4 and adapted to be1 turned by the crank 34. The "end of the spindle 22 extends beyond the pinion 32 and has a square end which entersa notch 36 in a bracket'37 secured to the outer face of the end 4, and when the parts are in place the sleeve 26 is supported by the bearing notch 12 of the latch 11. It will thus be seen thatthe'spim dles 22 and 24 areheld against rotation, and

when the parts are assembled'as described,-

turning the handle 34' will turn the pinion 32, and as this is fixed to the sleeve 26 of the'cap 25 it follows'tha-t the cans which are coupled together at their inner ends, will both'be revolv'ed, the dashers 27 and 30 being fixed to their respective spindles remaining stationary. These cans after the cream has been placed in them, are located in the casing and the casingpacked with ice'in the usual manner of ice cream freezers. The melted ice as it accumulates, will escape through. the slots 10 into .thedrip pan formed by the bottom 6 and guard strips or flanges 7. By providing independent spindles and connecting the cans together inner end to inn nerfend, the cans are closed at their inner We claim 1. In an ice cream freezer, the'combination with a case or container, of two cans arranged therein and coupled together at their inner ends, a dasher in each can, and means for holding said dashers in a stationary position, and means coupled with one of the cans for revolving the two cans simultaneously.

2. An ice cream freezer comprising a casing, two cans arranged inner end to inner end and adapted to have their said inner ends interlocked, an independent spindle in each can, means for holding the spindles against rotation, a dasher secured to each spindle, caps to close the ontenends of said cans, a pinion coupled with one 'fof said caps, and means for turning said pinion whereby both cans are turned, substantially as de scribed.

In testimony whereof, we hare signed this specification in the presence of two subscribing witnesses.
