LIQUID oooLER George John Huntley,

Baltimore, Mdi, assignor Inc., Baltimore, Md., acorporation of New York Application October 27, 1931. Serial No. 571,433 r 5 Claiins- (01. 257-229) Myv invention relates to improvements in liquid cooling apparatus and particularly to coolers used in connection with bottling machines to equalize before mixingv the Components of temperature of the the liquid being bottled, usually a beverage mixture of syrup'and plain or carbonated water. The object to reduce the excessive foaming or filling,

of ing at the time or" bottle differing temperatures same timesecure a higher speed in filling; and lessen of my invention is such mixtures caused by high and redients, and at the arbonation; greater ss ofgas and liquid;

providing an item'oi bottling equipment that is novel, efficient and especially adapted for use in climates where the temperature is abnormally high. Tests show that my c syrup temperature 25 to 30,

ooler rapidly lowers degrees Fahrenheit,

varying slightly according to the density of the liquid used. I attain by the construction, 7 'ments of parts hereinafter derstood that I do not the object of my invention combination and arrangedescribed and par claims, it being unlimit myself to the details of construction and combination of parts as shown herein. 7

My invention is illustrated ing drawing in which:

In the drawing like parts.

numerals indicate similar My liquid cooler as shown is comprised of a cylindrical tank 1 of suitably rust proofed sheet metal having mounted within it vertically two within the closed set in and through the tank the inner Mounted top 2, as at 3, is a helical coil 4 of rustless metal tubing, preferably copper coated inside and out with tin,

ably large diameter, which vertically of the coil axis, to tanceof the bottom 5 of the per end 3 of the coil 4, top 2, is mounted a head and of suitextends downward, within a short distank 1. On the upextruded above-the tank 6 having two tubular extensions, 7 and 8, of which branch 7 is connected to a water supply pipe 4 is thus adapted to convey a s 9. The tubular helical coil tream of water from 1 the water into the tank 1, and owing to the the inlet downward through the tank body'to a point near the tank bottom, and there discharge tank, where it will rise in the tank body, against air or gas compression in the tank, and surround the coil 4'exteriorly, submerging it to great extent. An outlet 10 in the tank bottom 5, of smaller diameter than coil 4,connected with a water pipe 11, conducts water 11a from the tank to the water filling station 12 ofa bottling outfit. The water, it will be noted, is cooled in a cooler 13 prior to its entrance to the method of its entrance and discharge from the said tank circulates inside same up around the helical coil 4 by which it enters, and changes constantly as it flows in and out during each bottle filling operation, at the same time rising and falling in level to some extent.

The helical coil 4 is thus intermittently bathed in the upper airor gas filled head of the tank 1, with evaporative cooling eiiect upon the coil exterior, while the lower part of the coil is submerged in an intermittently changing and flowing body of water. Through this helical coil 4 I pass the liquid tobe cooled before mixture with the said water. From a syrup tank 14, suitably located iorgravity feeding, a syrup pipe 15 passes to the head '6 of coil 4, which itenters by means of tubular extension 8 of said head, and then passes down inside said coil 4, concentric with same, as an inner helical coil 16, continuing past the lower termination 17 of coil 4 downward and outward through tank bottom 5, to the syrup filling station 18 of the bottling outfit. It will be noted that the syrup pipe 15 is of considerably smaller diameter than the helical tube coil 4 through which it passes, and is spaced from the walls thereof. As in beverages the usual proportions of mixture are one part of syrup to sixparts of water, it is obvious that the syrup supply pipe 15 may be of very small diameter and stream area in comparison with the stream of cold water in the outer coil 4 which it traverses and the body of cold water which surrounds the sail coil in the tank 1. Therefore the temper ature of the syrup 19, flowing in pipe 15 from the syrup tank 14 to the syrup filling station 18 of the bottling outfit, is so rapidly reduced during the passage of the syrup through the helical coil 4 and water body 11a in tank 1 that the syrup leaves the liquid cooler at the same, or approximately the same, temperature as the water body 11a from which the water supply flows. The syrup and the water, therefore, pass from my liquid cooler to their respective filling stations at an even temperature, thereby reducing to a minimum any Operation of the liquid cooler, as has been indicated, pressure on the water and syrup being assumed, is effected by first allowing the stream of cold water to flow sumciently to fill the helical coil 4 and the tank body and cool same to the Water temperature. Then the stream of syrup is allowed to flow from the syrup tank 14 down through the said water coil l and tank 1, in its pipe 15. Further operation is automatic as the bottling outfit is operated, the pressure on water and syrup duly charging the receptacles and changing by such outflow the tank content.

While it is preferable that the inner, or syrup, coil 16 should be concentric with and equi-distant from the surrounding Wall of the outer, or water, coil 4, in the double helical tubular coil that is a feature of my liquid cooler, it is not essential that the inner coil should be so centered. A simple, modified form of my liquid cooler is illustrated in Figure 3. The cylindrical closed tank 20 is the same as in the preferred form. The tubular helical coils 4 and 16 of water and syrup pipes are dispensed with and a plain cylindrical inner tank 21, of the same shape as the outer one, I

is mounted centrally in the Water tank 20 and spaced from the Walls thereof. A water supply pipe 22 feeds cold water into said tank 20 through a top inlet 23 and it flows out of the tank to the Water filling station of the bottling outfit through a bottom outlet 24 that is of lesser diameter than the supply pipe 22. A syrup pipe 25 enters through the tops of the outer Water tank20 and inner syrup cooling tank 21, as at 26 and 2'2, and feeds syrup into said inner tank 21. A syrup outlet pipe 28 conducts thecooled syrup from the bottom of the inner tank 21,.out through the bottom of said tank and the bottom of the outer, water, tank20, as at 29 and 30, whence it flows to the syrup filling station of the bottling outfit.

Operation of the modified form essentially the same as that of the preferred form. Cold water is allowed to flow into the outer tank 29 until'it is filled, to Whatever height air or gas pressure in the head will permit, and the tank cooled to water temperature. Syrup is then allowed to flow into the inner tank 21 until it is similarly filled with syrup. The inner tank 21 being of much less content than the outer tank 20 and submerged in the cold water which fills said outer tank 20, the syrup excess of temperature is quickly absorbed by the water, and syrup and Water flow from the tanks at the same temperature.

There can, of course, be considerable variation and modification of some or" the details shown Without departing from the spirit of the invention, and except as Where s ecifically noted in the appended claims, the invention is not to be understood to be limited to the exact details illustrated.
