ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 444,790, dated January 13, 1891. Application filed September 15, 1890. erial No. 365,089. (No model.)

To coZZ whom it may concern:

Be it known that we, VILLIAM T. BESSON- ETTE and CHARLES R. KING, citizens of the United States, and residents of Atlanta,in the countyof Fulton and State of Georgia,ha-ve invented certain new and useful Improvements in Ice-Cream Freezers; and we do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, whiclr form a part of this specification.

This invention relates to devices for refrigeratingliquid substances, and more especially having reference to such class of these devices as are known as ice-cream freezers,

and to that specific kind of freezers in which the refrigerant compound is contained within vessels revolving upon a horizontal axis, the object being to so improve this class of devices as to render them more useful, conven' ient, and economical, to which end these present improvements have been made, all of which will be hereinafter fully specified and claimed, and are shown in the accompanying drawings, in which- Figure 1 is a central longitudinal section through the casing, showing the cylinder entire with the exception of a small portion broken away to show the arrangement and form of the cups. Fig. 2 is aview also in central longitudinal section through the casing, showing the reverse side from that sh own in Fig. 1, the hollow journal being shown. Fig. 3 is a horizontal section of the cylinder, showing the arrangement and a means for fastening the cups in their places and the covers thereon. Fig. l is a cross section through a portion of the cylinder, showing the setting of the cups; and Fig. 5 is a longitudinal section thereof.

In the figures like reference-marks indicate corresponding parts in all the views.

The casingAis for the purpose of insulation, and hence may be of any form and material consistent with such function; In the construction shown it is composed of wood and is in two parts or sections a and 0., in the bottom section a of which run the journals 1) and b of the cylinder B, each of which is fitted in a semicircular notch in the sides of said part a, the partahaving corresponding notches and fitting close down upon the lower half of the casing, thus thoroughly incasing and insulating the cylinder. The journal I) has suitably secured therein a hand-crank 19 by which it is revolved, and the journal b is hollow, and through it communication is had with the interior for the introduction of the refrigerant into the cylinder B. Said cylinder B is composed of sheet metal, preferably tin-plate, and besides the construction to j ournals just described has a series of apertures in its periphery, in which is inserted an equal number, as many as desired, of the cups 0, which are in the construction shown flanged outwardly around their tops for purposes of suspension,and areslightlytaperingin formto facilitate the removal of cream; butitis obvious that many other equivalent means might be employed for holding the cups from falling through the openings in the cylinder, and by flowing with water at a normal temperature the cream can be readily removed from the cups. The taper, however, obviates the necessity of this slight warming, and is hence preferable.

In order to insure a water-tight joint between the cupsC and the peripheral surface of the cylinder B around the apertures, a gum ring D is placed in said joint,being normally stretched onto the cup 0, so that when said cup is set into its place in the cylinder and compression is brought to bear thereon the rubber fits closely into any inequality of the surfaces of either the cup-flange or the cylinder. The cover E is pressed down over the flange on the cup C by means of the screw f, which is screw-threaded into the clip F, the hooks on the end of which clip engage with reversed correspouding hooks G, which are secured to the periphery of the cylinder. A gasket e, of rubber or other elastic material, is fit ted in place directly upon the flange of the cup. It is obvious that other construction might be employed for securing the cups 0 in place and the sealing-covers E thereon; but this form of construction is preferable by reason of its extreme simplicity.

If desired, cups C may be inserted in the ends of the cylinder, either without orin connection with those inserted in the peripheral Wall of the cylinder. A slight advantage would be had by this construction inasmuch 5 as a flat surface would be had for the flange on the cup to bear against.

Having thus described our invention, What we claim as new, and desire to secure by Lets ters Patent, is-

edges of their mouths flanged and seated in IS openings in the periphery of the vessel, the covers E, the hooks G, secured to the periphery of the vessel near the mouths of the cups, the clips F, engaging with the said hooks, and the screwsf, substantially as and for the 20 purpose specified.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
