ICE-MAKING APIPABATUIS.

'To all whom it may concern: l Be it known that I, Ji-nrn s Hones, a citi- States, residing in Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful In; pro vements in Ice-Making Apparatus, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to. make and use the same, reference being had to the ings, forming part of this specification.

Y My invention relates to certain improvements in apparatus for manufacturing blocks of ice and it has reference more particularly portable vessel in which the iceblock is formed.

' It is the purpose of my inv ntion, as will more fully hereinafter appear, to make the can more durable and to increase its elliciency, and particularly incases where the ice-is formed from raw or undistilled water, though of course distilled water maybe used. Myinvention is further characterized by havingthe can with its insulating or freezing-retarding pocket and its air-injecting pipe made as a unitary article of commerce or manufacture. With these and other objects in view my invention consists in the various novel and peculiar arrangements and combinations of the several different parts of the apparatus,

I all as hereinafter fully set forth, and then pointed out in the claims.

I have illustratedtypes of my invention in the accompanying drawings, wherein Figurel is a perspective view of my improved ice can. Fig. 2 is a central vertical sectional view of the can shown in Fig. 1. "Fig.3 is a vertical sectional view of an ordinary freezing-tank showing one of my ice cans placed therein and with a block of ice formed in the can. Fig. 4 is a top plan view of the ice can with a block of ice formed therein. F ig. portion of my improved can, the view showing the pocketed side of the can and a modified form ofair-injecting pipe or duct. Fig. 6 is'a'top plan view of my improved can in which the air pocket-is used' on two opposite sides of the one .of said pockets. This view block of ice completely structionofcan.

accompanying draw-' can with air-injecting pipe in formed in this con-' Patented Dec. 3 0,19 13. Serial N0. 704,118.

the can, one piece of sheet metal may be used to form three of the sides 5, (3 and 7 and the fourth side 8 may be made of a single piece flanged at each of its side edges 9- and 10 so as to embrace the free edges of the sides 5 and 7. A separate piece of sheet metal 11 of suitablesize has its side edges flanged at 12 and 13 and near its bottom it is formed with a shoulder 14 with a depending liangc 15. This piece of sheet metal. is placed upon one of the sides of the. can, preferably the side 8, so that the flanges l2 and 13 thereof lie against the flanges f) and 10 respectively of the side 8. These parts are then secured together by means of suitable rivets 1c and 17 which pass through the llang'cs and'likewisc the edges of the sides ,5 and 7 of the can so that one set of rivets serves to hold these three parts together, and with the use of solder these joints are made water-tight. The bottom flange 15 of the pocket-forming piece of sheet metal 11 is secured to the lower edge of the side 8 of the can by the series of rivets at which have already been described, and this joint is likewise soldered to make it water-tight.

may be formed from one piece of sheet metal as indicated in,Fig. 5, and also Fig. 7, in which construction but one side scam in the can is necessary, and this may be made at one of the corners where the pocket is located. If desired, however, the can may be made in the ordinary way in which a single sheet of metal is used for each of thc four sides,-

with a riveted and soldered seam down each corner of the can.

T he'pocket formed on the can is watertight and it provides upon its'interior an air space 18 which extends practically over the entire side in the com-itruction shown herein, though the area. of the pocket may be more .or less contracted in respect to. the width of the side of the can upon which it is extending sides thereof, and it If preferred, the'four sides of the can Referring to the drawings, in which like.

located. The air space of be comparatively narrow, and yet it will serve to insulate or retard the freezing action within the zone of the pocket, when the can is placed in the freezing-mixture for the pur-- pose of freczing the water contained in the Call. i

In Fig. 5, in which the can is shown as having its four sides formed of one piece sheet metal the pocket 18 is made by having the sheet metal piece 11 with its fianged edges placed within the can and riveted and hereinbefore described.

provided at one end with theair-pocket 18..

) "Within the air-pocket 18 is arranged an air-in ecting pipe 20 which v1s suitably secured to the side of the can and has its troduc ed into the within the pocket and near The channel 21 1s in communication metal bent into with side flanges 27 and 28 and a bottom lower end threaded and screwed into a.

threaded channei 21 formed in a fixture 22 whichis made fast to the the bottom there of. with the interior of the can by meansof an aperture or duct 23,- and the channel 21 is continued below the level of the duct 23, so as to form a cavity or catch-all 24 in which foreign matter contained in the air may accumulate. The upper end of the air pipe means of a friction joint or air-pipe 20 is secured substantially on the center line of the side of the can within the pocket, and when in operation the elbow- 25 is coupled with the air supply pipe,:

which is generally a flexible tube,

as shown at 26 in Fig. 3.

In. Fig. 5, I show a modified form of the air pipe 20 which is constructed of'sheet a. trough-shaped structure where the trough-shaped member flange 29,

the respective flanges of the is closed,

trouglushaped member being riveted and soldered water-tight to the exterior of the side of the can. At" suitable points on a vertical line in the center of the side of the can I form small perforations '30 for placing the interior of the air-duct 20 in communication with the interior of the can, so that a series of air jets maybe incan in a vertical plane. Where the series of air-"injecting openings-80 are used as. soonas the lowermost one is closed by the'formation of the ice the ones above it continue in use and so on through the series of openings. In this way the air may be injected into the body of water from which the ice is formed until practically all of the body of water is frozen.

this pocket may side of the can "connected with the elbow 25 20 is provided with an elbow piece .which is removably secured thereto by otherwise; This" about twenty-three inches- In Fig. 3 I show my improved ca "as placed within an ordinary containing afreezing medium 32wh1ch .is usually brine at a low temperature which temperature is created and maintained by the use of ordinary ammonia pipes are not shown. In this figure, the ice-block 33 is shown as practically completed and in this conditionthe can 'may be removed from the tank'and the ice-block drawn from the can. A further freezing however will reduce the size of the central cavity or core 34 of the ice-block and cause it to assume subas shown in Fig. Y

stantially the dimensions t. This, however, is amatter of expediency and depends upon whether the freezing process be shortened or prolonged, and in cases where it is prolonged until all the water in the can is frozen, the core contains what is known as white ice instead of being constituted by a narrow space or pocket in thefcenter of the ice-block, as is the case where the freezing process is shortened.

Throughout the freezing action air-is 1ntroduced into the body of water from which the ice is formed, from a pipe 26"which is of the air injecting pipe 20-- and it is forced into the 23 located inthe lower part of the can on the center line of the pocketed-side thefreezing action and substantially uniform effect upon all fair or-insulating pocket is located and where the-airis injected 'into the I sult that the last portion of the ice-forming I is that located substan tially in theplane that is vertical and cen can, with ..,the re-.

water? that is frozen tral in respect to onehorizontal dimension of the ice-block." This unfrozen portion or core 34: is thus centralized in a vertical plane in the ice-block and where one pocket only is used the core or space 34: is located nearer to the insulated or pocketed side'of the can than it is to. the opposite side. -Where, however, the can is provided with pockets upon.

' Fig. 6-, the

two opposite sides as shownin core .or cavity .34 is substantially 'an-eq'ual distance from each' pocketed side. and is of course centralized between the two opposite uninsulated' sides of the can. Where the commercial size of. the ice-cake is about forty inches deep by about twenty-three inches by eleven lnches in, its othertwo-dimensions, I make the can of suflicient depth to have the ice-block forty inches deep, and I make the horizontal dimensions of-the can by twenty-two freezing tank 31 which I body of water t rough the duct or opening thereof. 1 The air is thus introduced for the well known purpose of slightly agi tatingthe ice-forming Water during the process of freezing in 1 'order'to produce clear ice.

In. the use of this ice can, as just described,-

takes place with full 55 the pipe is not inches and arrange the air-pocket.- on'the twei'ity-two inch side of the can. In making the ice-block in this can, the core 34 being centralized as block is remo block in half, of the core using the plane of the core as the cuttingv line, and I thereby obtain two commercial sized cakes of clear ice which is free from core ice. here, however, the morev desirable clear manded, and it is not objectionable to have llhG'COIl'lHlCICltll cake contain a core or cavity, I make the pocketed-canabout half of the twenty-two. iiich horizontal dimension, namely eleven inches, as shown in Fig.7, leaving the other dimensions as described, and in this can there may be formed one cake of ice 35, of commercial size, with the core 34 incorporated in the cake, and which core is left in the cake. The air pipe 20 which I have herewith shown passes through an opening in the lug or bracket 39 on the side of the can near the upper end thereof and makes a snug fit therewith in order to hold it fast. The pipe may also be soldered in place if desirec.

' I find from the use of this can that by making the cross-sectional area of the iceblock substantially sectional area of th cake, that the time required to freeze such a block is considerably lessened in proportion to that required where the icc bloclc is made ved from the can, I cut the icethe commercial sized cake. Furthermore, by having the can with its insulating-pocket and its air-injecting pipe forming a nent part of the structure, so that the de-' scribed parts constitute a unitary commercial article, much in handling the cans, when the ice is harvested or drawn from the cans, for in the construction where an independent or separate airi1 ijecting=pipe is employed and the same is suspended within the vice'can, it requires separate handling and careful adjustlnent'to locate the pipeinits properplace' to. prevent its being the iceb lock, and when it is frozen in the I ice-block considerable difficulty results in having to thaw or cut it out of the block. It will also be having the air-pipe located within the pocket, only protected from the ac.- tion of the brine during the freezing process, butit is also protected .from' injury when the cans are removed from the freezing-tank and manipulated-in the removal of the iceblock, for the pipe is completely housed by the pocket. Another most important advantageof this improved'can is that the ordinary service water in what is called raw condition, that is undistilled, may be used for making the block of ice from which may be ake of ice is not deequal to twice the cross-- e commercial. size of ice more than-twice the cross-sectional area oi" perma time and labor is saved prematurely frozen into observed that by .virtue of" I cut commercial described, when the on substantially the center line I sized cakes of ice that are clear.

It will be understood that I do not limit my invention to the particular cons'tructio'ns herein shown, as various .modificati'ons may be made therein, without, however, departing from the spirit ofmy invention.
