ICE BOX FOR USE AT SODA FOUNTAINS .Filed Dec. s,

NTFS-:IN EN' as Will he clearly understood from Figure 1; or, said cover` 17 may serve to close the top ot' the ico storage chamber 12 when it. is not extended upwards as shown but ifa on a levelwith the top of the refrigerator.

Supported or seated on an appropriate stand or footpiece 18 in the lower part of the ire-storage chamber l2 is a tray or receptacle 19 for a quantity of salt 20 on which the broken ice 21 is stacked until said chain-- ber 12 and extension 16 are filled. Arranged in a convenient position within the brine tank 11 is the stand-pipe or overflow 22, which is extended down through the bottom of the refrigerator and elbowed at 23 to a substantially horizontal pipe 2% having:l a T 25 at its other end from which a branch pie 26 is extended down into a Suitable setn tling tank, barrel or the like 27 in the cellar or basement, said branch pipe 26 having fitted therein an appropriate shut-oil valve or stop cock 28 Alor a purpose later on explainech Extended upwards from the afore said T 25 is a pipe 29 connected into the suction end or inlet 3() of an ap iropriate circulating pump Ill. and from t e outlet or discharge 32 of said pump 31 is an in- -verted U-shaped pipe 253 elbowed at 34e and extended into an appropriate union 35, that constitutes a coupling for a. pipe 3G concentric with and of larger diameter than the aforementioned stand-pipe or overilow At the upper end of the pipe 36 and within the brine tank 11 is a transverselydisposed union 37 from which is branched a pipe 38 extending substantially aloner the floor or inner bottom of the refrigerator 5 through the inverted 'trough or channel 123 and icestorage chamber 12, its free end being litted with an elbow 39 from which projects vertically upwards a pipe 40 haviiiga ibranch Ll1 at its upper end terminatingf in a nozzle or outlet 42 axially central o' -the upper part of the said ice-storage chamber l2. In order to provide an ellectire and reliable support for the ice-cream cans or other receptacles 43 when immersed in the sohr tion within the brine tank 1l l preferably employ a false or inner cover 4l appropriately supported on a surrounding' flangee5, the apertures in said cover el having espansible ri'ng flanges 46 which serre to inaintain the cans 43 perfectly vertical, said ei;- pansible ring: flanges 46 being employed to accommodate structural inequalities in said cans. lt is also to he observed that the cans or other receptacles 43 are. supported or suspended Within the brine tank l1 lj the usual bead or lip 47 at or near their upper edge whereby the ordinary covers i8 thereH 4for can be freely removed and replaced. Still further it is to be noted that the cans or other receptacles i3 are suspended from. the false or inner cover le so that they are completely surrounded lijf the brine solution amener at a level so ae not to contact with or foal either the channel or trough i37 pipe 38 or stand-pipe 22. Thus it will be readily seen and very clearly understood that when the ordinary cover or lid 9 is raised comparatively little er no cold energy can escape save that which is liberated when the cover of .one indiif'idual can or other receptacle a3 is removed to take ice cream therefrom or for replenishintr purposes.

ln the modilied form of the invention shown in'lfirfure 3 it is to be observed that the ice-chamber 16 is made as a detached unit and is connected up to the refrigerator bv means ot' a coupling; through which the pip-e 38 is axially conducted so that a supporting passage is provided for the flow of the solution from said chamber into the brine tank ll as will be readily understood by those acquainted with the art to which this invention appertains.

Still further I wish to point out that in the form of the invention illustrated by Figures l. and 2 the ilividii'rel wall between the brine tanl: ll and iee-storagfe chamber 12 mar be constructed as vertically movable slide so thatI whenever desired broken ice maybe allo-ered to 'flow into the brine-tank ll.

ln order to provide a simple and effective means for regulating or varying' the overflow level of the brine solution in the brine tank l1 il employ the means illustrated by Figure 5 and which consists in fitting an adjustable sleeve or coupling` 50'on the upper end olE the stand pipe the upper pair, 51 et said sleeve 50 being fashioned slightly iunnelshaped or upwardly and outwardly flared to constitute a friction seat 'l'or the correspondingly tapered lower end eta tubular nipple 52. lt will or course be readily seen that when the nipple 52 is frictionally seated in the upper part of the sleeve or coupling that the height of the stand-pipe 22 `will he raised with the consequential raising: of the overflow level 0fthe waste brine solution. bifiously two er more such nipples 52 may he provided to give varyingl overflow levelsas will be rerulilj,f comprehended by those acquainted 4with the art to which my invention zipper taies.

From the foregoing description and an examination ot" the drawings it Awill be apparent that by my present invention there is provided what may he termed a refrigerator Fwith which is associated a circulating system whereby the less dense or Warmer sola tion passing to waste or overflowing may be circulated back through the refrigerator into the iceetorage chamber l2 thereby red te become recharged with cold energy 'betere reentfering' the brine tank ll. ln use the valve or stop cock 28 'will kept open whereby 'the Warnier or gradually riem-g up. per rit/rata, or surta@ o." weakened arme sologli llt)
