AIEIPARATUS FOR MAKING ICE.

Application filed September 19, 191

lle it known that we, Tnonas l3. lllAGIN- xis, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, and Tiioims GAFFNRY, a citizen oi? the United States, residing in the city of St. Louis, State of Missouri, have invented certain new and useful improvements in Apparatus for Making" lee, of which the following is a specification.

.This vinvention relates to apparatus for making ice, and more particularly to an apparatus capable of making clear ice from undistilled water. v

Among the salient objects of the invention are to provide, in an apparatus of the character above referred to, an improved means for furnishing air to a plurality of individual tanks for agitating the water during freezing; to provide a construction in which the vertical tube which extends down into the water will be held from movement to a' position where there is danger of freezing the tube into the ice cake; to provide a simple and eflicient means by which the amount of air passing to the vertical tubes is controlled; to utilize. the conduit, from which the vertically extending tube is suspended, as a means for holding the can in its assembled position in the frame; to provide a construction in which a plurality of the can units are all provided with air from a common, source and a minimum number of lateral pipes employed for such purposes; to so mount the, vertical'tubes and their late ally extending conduits which carry them that these parts may be readily re moved to permit the individual withdrawal of the cans from the frame in case the contents ofthe cans freeze unequally; to per mit of the use of a single spring for resiliently holding two or more of the vertical tube supports in assembled position; and in general to provide an improved apparatus by which clear ice may be manufactured from undistilled Water.

ln the drawings Figure 1 is view, partly in section, showing two cans in position in the frame. Fig. 2 is an enlarged fragmentary sectional view showing in de-- tail the assembled. position of the parts.

Referring in detail to the embodiment of our invention shown in the drawings, the individual cans or receptacles are designated by the reference characters 1, 1, etc. At

its upper end, each of these cans is provided with a return bend flange 2, preferably i'ornied to surround a reinforcing member 3. The lower end of this flange rests upon a shoulder el tormed in the cross bars 5. A similar shoulder (3 is provided in the longitudinally extending bars 7, the bars 5 and '7 forming a frame work by means of which the cans are suspended in brine or other freezing medium.

The frame work above mentioned is so proportioned in relation to the individual cans that when the latter are inserted in the frame work the flanged portions 2 will rest upon the shoulders 4 and 6 and are secured in this position in the following manner: Along one or more of the longitudinally extending bars7 is positioned a conduit 8 leading from a main supply pipe 9, and at the intersection of one of the transverse bars 5 with the longitudinally extending bar 7, the conduit 8 has a T coupling 10 from which extends a transverse conduit 11 terminating in a hollow head 12. At one of its sides, and preferably at both sides, the head 12 is provided with lateral openings 13 and I l the size of these openings depending on the amount of air it is desired shall be carried to the tubes 15 and 15" which extend downwardly into the cans 'l and l. The tubes 16 and 16 which connect the head 12 with the vertically extending tubes 15 and 15, do not extend entirely across the cans but are threaded into a T coupling 18 from. the opposite end of which there extends a solid bar or rod 17 having one end threaded into the coupling 18, and

'its outer end 19 extending into a socliet 20 formed in the transverse bar 5. lhis construction permits of a single transverse pipe 11 furnishing air-to two or-more of the individual ice cans, and also avoids the necessit v of using an individual spring for each bar l7. As clearly shown in Fig. 2

an axis, and is also longitudinally adjustable along such axes by pressing the end 19. against the abutment 24: and thus compressmg the spring 22. The conduits 8 and 11 are preferably housed Within a series of inverted channel shaped casings 27 and 28 which rest on top of the respective bars 5 and 7.

In use, the various indivdual icecans or units are filled with water and positioned \vithinthe main frame. The tubes 15 and 15' are then inserted in place in the following manner: The end 19 is placed against the abutment Z-t and the latter pushed inward to compress the spring a sufiicient distance to allow the end to be sprung into the seat 26 of the head 12. Air isthen forced from the main supply pipe 9 through the conduits 8, 11 and 16 and 16 to the individual vertical tubes 15 and 15 and through a plurality of apertures 29 is discharged into the water while the latter is freezing. Owing to the fact that the brine or other freezing medium is positioned exterior of the cans, the water at the center will be the last to freeze, The air forced into th water will tend to carry the gases out with the air and to draw the sediment toward'the center. In order to prevent the employment of the air conduits as a securing means for holding the individual ice cans in proper position in the frames.

V'Vhile we have shown and described a particular embodiment of our invention, We do not desire to limit it to any details of construction except as specified in the following claims:

We claim as our invention:

1. In apparatus for making ice, the combination with a plurality of individu lly removable receptacles, of a frame for solid receptacles comprising a plurality of inter secting bars, a supply pipe extending along the face of one of said intersecting bars, one end of said supply pipe having alead to a source of air under pressure, and said pipe at its opposite end being provided With a lateral seat, a transversely extending eonduit baring an open end engaging said seat and an apertured vertical tube depending from said conduit;

2. In apparatus for making ice, the combination with a plurality of individually removable receptacles, of a frame for said receptacles comprising a plurality of intersecting bars, a supply pipe extending along one of said intersecting bars, one end of said supply pipe havin a lead to a source of air under pressure, a c iambered head con neeted to the opposite end of said supply pipe and being apertured upon opposite sides, transversely extending conduits pivotally engaging and in open commumcatlonwith said chambered head, and an apertured vertical tube depending from each of said conduits into one of said receptacles.

3. In apparatus for making ice, the combination with a plurality of individually removable receptacles, of a frame for said re eeptac'les comprising a plurality of intersecting bars provided with shoulder portions forming seats for the receptacles, said receptacles ha ing Flanged portions engagingsaid seats, a supply pipe extending along the upper face of said intersecting bars, one end of, said supply pipe having a lead to a sourceof air under pressure, a chainb'ered head connected to the opposite end of said supply pipe, said chambered head being apertured upon opposite sides and having a tapered seat surrounding said aperture, a transversely extendingconduit having a tapered end engaging said seat, an apertured vertical tube depending from said conduit into the said receptacle, a member forming a continuation of said transverse conduit and a seat in one of the intersecting bars for receiving the free end of said member to permit the engagement and disengagement of the conduit With said head when the can is in position'in said frame.
