CANDY-COOLING TABLE.

Specification of Letters Patent.

lratented April 23, 1907.

Application filed December 20, 1906. Serial 1%. 348,776.

To {I/ZZ whom it may concern:

Be it known that I, JAMES R. WINDSOR, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Candy-Cooling Table, of which the following is a specification.

This invention relates to that class of candy cooling tables in which the table top is formed of plate metal and a water receptacle is formed directly under the table top so that a large body of water may be held in contact with the under surface of the table top. Heretofore the efficiency of cooling tables of this kindhas been impaired because the heated water remained at the top of the receptacle in contact with the table top and the cool water remained near the bottom of the receptacle.

My object is to provide a table of this kind in which the cool water in the receptacle is forced and temporarily held against the under surface of the table top and as soon as it has been warmed by contact with the table top, it will descend and becarried off throu h the overflow pipe so that the cooling e' F1.

ciency of the table top will be increased.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of a candy cooling table embodying my invention. Figure 2 shows a top or plan view of same with the table top removed. Figure 3 shows an enlarged detail sectional view through a portion of the table top with lines indicating the direction of flow of water from the supply pipes to the under surface of the table top, and Figure 4 shows a central, longitudinal sectional view of a table embodyingmy inventioh.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate a supporting frame of the table. Mounted upon the frame is a water receptacle comprising a body portion 11 with its side edges inclined upwardly.

12 indicates the table top preferably made of plate metal and connected by rivets 13 with the receptacle 11 to form a Water tight chamber and a flat topped table.

The water supply pipe is indicated by the numeral 14 and is provided with a valve 15. This water pipe projects upwardly into the receptacle 11 at about the central portion thereof. Connected to and communicating with the top of the supply pipe 14 are two supply pipes 16 lying within the receptacle 11 near the bottom thereof and curved backwardly and forwardly across the receptacle to points near the ends of the receptacle. The ends of said pipes are closed by the caps 17 and water is permitted to discharge from said pipes through the openings 18 therein, which openings are so arranged that they will discharge water upwardly and laterally at an angle of aboutforty-five degrees. The transversely extending portions of the pipe 16 are arranged about equal distances apart and the parts are so arranged and proportioned that 'the jets or sprays of water coming from two adjacent portions of pipes 16 will cross each other just before striking the top 12, this feature being clearly illustrated in Figure 3. By this arrangement, the cooling efficiency of the water is at its maximum because the receptacle is completely filled with water which is in engagement with the under surface of the table top and furthermore the jets or sprays of water coming direct from the supply pipe strike upon the under surface of the table top at an angle of about forty-five degrees. The jets or sprays from the parallel portions of the supply pipe cross a short distance below the table top and these cross currents tend to hold the water in contact with the table top for a space of time long enough to permit the Water to reduce the temperature of the table top and to become warm in so doing.

I have provided for carrying off the warmed water from the receptacle 11 as follows:

Near one end of the receptacle is a drain pipe 19 leading from a point within the interior of the receptacle spaced apart a short distance from the top 12. This pipe extends first downwardly, then horizontally at the point marked 20, then upwardly at 21 to a point slightly above the under surface of the table top and then downwardly at 22 to a point of discharge. A by-pass 23 is. provided communicating with the bottom of the water receptacle 11 and discharging into the pipe 22. A cut-0E valve 24 is placed in this by-pass which valve may be opened when it is desired to drain out all of the water in the receptacle. An air vent valve 25 is placed in the top of the water receptacle.

In practical use and assuming that a quantity of hot candy is poured upon the table top, the water contained in the water receptacle will rapidly become heated and as the hot water normally rises to the top, the water will not materially aid in lowering the temperature of the table top. However, when the valve is open a current of cold water under pressure is forced through the pipe 14 and the openings 18 of the pipes 16. This will cause a series of jets or sprays of water to pass from the pipes 16 upwardly through the water in the receptacle at an angle of about forty-five degrees until these jets or sprays strike upon the top 12. On account of the arrangement by which these jets or sprays of water are caused to cross each other just before striking the top, the cold water will be temporarily held in contact with the top,

thus forcing the heated Water downwardly where it is drawn off. -However, on account of its tendency to rise the hottest portion of the water in the water receptacle will be a short distance under the top 12 and for this reason the drain pipe 20 is placed with its receiving end slightly spaced apart from the table top. This drainage pipe projects to a point above the table top so that the water in the water receptacle will always fill the receptacle. I have discovered that by having the water receptacle full of water, the jets or sprays of cold water from the supply pipe are held in contact with the table top for a sufficient length of time for the water to absorb heat from the table top and hence the cooling efliciency of the water is much greater than if the receptacle was not full and the jets or sprays of water were forced through the air against the table top. Then if it is desired to remove all of the water from the receptacle, the operator opens the valve 24.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, therefor is 1. In a candy cooling table, the combination of a table top, a water receptacle beneath the tabletop, water supply pipes introduced into said receptacle and provided with openings to discharge upwardly against the table top and means for drawing off heated water from the receptacle without lowering the water level.

2. A candy cooling table, comprising a table top, a water receptacle beneath the table top, a water supply pipe within the receptacle having openings therein to discharge upwardly and laterally in a direction to ward the table top and means for drawing off the heated water from the water receptacle without lowering the Water level therein.

3. A candy cooling table, comprising a table top, a Water receptacle beneath the table top, a water supply pipe leading to the interior of the water receptacle, a pipe communicating with the supply pipe and eX- tended backwardly and forwardly across the receptacle, said pipe provided with openings to discharge water upwardly and laterally toward the table top at such angles that the streams from two adjacent portions of the pipe will cross each other near the table top.
