My invention relates to a new and usefulmanu facture, i. e., a protective collar and‘over?ow bracket, made of cast iron or other suitable ma 2 ‘ the accompanying drawing, and. particularly pointed out in the appended claims. ‘Referring now to ‘the drawing: terial, for use in connection with spiral cooler coil such as are commonly used by taverns for cooling liquids or beverages and which make use ‘ of ice or mechanical refrigeration. In apparatus for cooling beverages, it is com mon practice to provide standard cylindrically sleeved coil cooling units which furnish, n0 ‘pro 10 tection to the spiral coil‘pipe from injury in the Fig. 1 is 'a longitudinal section of my invention showing a position of protective collar over and ?anged into the top of coil pipe cylindrical sleeve unit of standard refrigeration or beverage cooling systems; ' . , Fig.v 2 is a bottom plan view of my invention, viewed on line 2-"—2 of Fig. 1. i ‘ Fig. 3 is a detail cross sectional View of ?anged collar and bracket, viewed on line 3-3 of Fig. 1, process of poking and packing ice. into the sur showing one form of bracket for attachment to rounding ice chamber, as a result of which prac an ice chest or Wall of an icing chamber, and tice the coil pipe will in time expand and stretch also showing the position of the bracket above 15 upwardly because of pressure due to manual slot and above the normal overflow level. packing of ice andwork up and over the top Fig. 415 an elevational view of my invention rim of the cylindrical sleeve and will otherwise be distorted, displaced or damaged.
