. Application tiled August 22, 1893. Serlal No. 483,733. (No model.)

To a/Z whom may con/cern:

Be it known that I, JAMES M. SKIPPEE, a

yci tizen of the United States, residing at Granbury, in the county of Hood and State of Texas, haveinvented a new and useful Ice- Cream Freezer, of which the following is a specification.

My invention relates to improvements in ice-cream freezers; and the objects in view are to provide a machine for elfectually and with slight labor freezing cream; to be so constructed as to freeze the cream into sticks o f merchantable size andadapted for retail trade; and, furthermore, to provide for a simultaneous manufacture of ice, so that as the cream is frozen water may be congealed forming ice that may be subsequently employed in the freezer or otherwise.

Various other objects and Ladvantages of the invention will appear in the following description and the vnovel features thereof `will be particularly pointed out in the-claims.

Referring to the drawingsz--Figure 1 is a perspective view of an ice-cream freezer embodying my invention. Fig. 2 is a similar view in detail of the agitator. Fig. 3 is a transverse vertical section of the machine. Fig'. 4 is a transverse horizontal sectional view v Fig. 5 is a detail of one of the cream-tubes.

Like numerals of reference indicate like parts in all the iguresof the drawings.

In carrying out `my invention I employ a cylindrical casing 1, which, in the present instance, is designed to be stationarily mounted upon a suitable base, as a bench or a pushcart, when the freezer is employed by street vendors. The casing has its upper end provided with a circular opening formed therein, its edges leaving the annular flange 2,*and

A a corresponding flange 3 is secured to the invertical bearing-stud or pin 7, and in the present instance there vis mounted rotatably thereon a circular frame or disk 8, from the center of which there rises a vertical shaft 9. This disk 8 is an open disk, as shown, so as to render it light and permit of a circulation of the ice and water therethrough, and is at intervalsalong its periphery or near its rim provided with pairs of vertical standards 10, the same being X-shaped in crosssection, and between each pair there is seated a water receptacle or can 11, the same being removable and held in vertical position. An inner cylinder 12 is provided with a central tubular bore 13 that lits over the shaft 9, and said inner cylinder is secured to the under side of the main circular cover 14 that surmounts the outer casing. This cover 14 is provided with a depending annular flange 15 that fits in a double flange 16 with which the top of the outer cylinder is provided, the said double liange forming a water-seal in which the flange 15 of the cover 14 fits. The cover is further provided at one side with a connection with a removable 'lid-19, the opening 17 being of such size as to permit of the upward withdrawal therethrough of the Water-cans 11 heretofore mentioned. The bottom of the cylinder 12 is provided with a disk 20 which projects outward beyond the cylinder, and above the same the cylinder is encircled by a flange 2l. The flange 2l is provided v l lwith perforations 22 located at intervals theresame. lf desired the machine maybe mount-v ed upon a hand-cart and through ordinary gearing with the hub or axle thereof, be rotated. The inner and outer cylinders, it will be seen, are, in the presentinstance, intended to be stationary while the disk revolves, but it will be obvious that `the disk may be stationary and the inner and outer cylinders revolved if desired, such being Within my invention.

Located in the openings 23 and 22 and in the openings 5 and e is a series of cream tubes 27, the same being in this instance rectangular in cross-section and loosely itting in the openings so that they may be readily withdrawn after a withdrawal of the corks or stoppers that are located in the collars 5. The inner series of tubes rests upon the disk 20 of the inner cylinder, while the outer series of tubes rests upon the bottom of the external cylinder or casing.

In operation the cream-tubes are partially filled, as are also the water-cans ll partially iilled, the tubes placed in position, and the cans likewise are placed and introduced successively in the opening in the cover 14. After this ice and salt are introduced in proper proportions and quantities into the external cylinder, and in fact it may be introduced into the inner cylinder through a covered opening 28 and as shown said inner cylinder in such instance communicating with the ex` ternal cylinder through suitable openings 29 formed in the side thereof. The machine heing set in motion, it will be seen, that the movement of the ice will cause the tubes to rotate each independent of the other and the strong cold brine will so reduce the temperature of the water in the water-cans as to freeze the water into bricks corresponding in shape to the cans. It the cream is not sold as soon as f rozen, the tubes may be removed and inserted through the opening 2S into the inner cylinder and there kept cold and in salable condition, and other tubes substituted for them. As the water is frozen in the water'cans, the cans are successively withdrawn through the reetangulL r opening in the cover and the ice employe either in the freezer or for other purposes. This ice attachment is particularly adapted to be einployed when the machine is used by street vendors or in case of all-day picnics, excursions, die.

It will be obvious that the water-freezing attachment may be omitted, and instead einploy one or two cylinders and the described accessories, and revolve the inner cylinder within the outer cylinder or the outer cylinder around the inner cylinder, such operation being readily secured by an obvious rearrangement of the mechanism.

I do not limit my invention to the precise details of construction herein shown and de scribed, but hold that I may vary the same to any degree and extent Within the knowledge of the skilled mechanic.

Having described my invention, what I claim is 1. In an ice-cream freezer, the combination with an inner and an outer cylinder, holders arranged in said cylinders and having their upper ends covered, and icecream receiving tubes loosely and removably seated for independent location in the holders, substantially as speciiied.
