Application October 4, 1947, Serial No. 777,907

3 Claims. 1

This. invention relates to the syrup rail assemlily of my soda fountain wherein the manufacture of the stainless steel top capping is described inmy copending application Serial No. 761,466 filed July 17, 1947.

It is the object of my invention to produce a syrup. rail that can be economically produced and is. convenient to the dispensing of soda fountain. drinks and can be easily and thoroughly cleaned.

A second object of my invention is to produce a syrup rail that is cooled with a minimum amount of power expenditure.

A third object of my invention is to provide a syrup. rail that is artistic in design and yet is efficient in operation and can be economically constructed.

In the drawings:

Fig. 1 is, an isometric showing of my syrup rail as constructed and associated with my top capping for a soda fountain unit.

Fig. 2. is a cross section of the syrup rail along the line 22 of Fig. 1.

Fig. 3 is. a side view of a container to be mounted in. and forming a part of my syrup rail.

Fig. 4 shows the detent means of fastening the cover on the containers forming a part of my syrup rail.

Fig. 5 is. .a detail of the specific cover for the syrup containers for sundaes.

Fig. 6 is a. cooling unit for my syrup rail.

My soda fountain top capping 1, formed according to my copending application, has the upwardly and forwardly inclined flange 2, a depressed area 3 and a ridge 4 extending around the front and sides of the top surface of the top capping as fully described in my copending aplication. As described therein, the upwardly and forwardly inclined flange 2 terminates at the top in a curl 5 which forms the lower support for the rectangular syrup dispensing units 5, including container 6', and the top capping is completed by the top back panel 1 and the rear end panels 8, which are flanged over at 9 to fill in the space between the curl 5 and the top back panel 1. The rear of the top back panel 7 is flanged over at In (Fig. 2) and the rear end panels 8 are flanged over at H for fastening on the rear panel I2. The top back panel 1 is flanged over at its front side at I3 which flange is again flanged over at M. Centrally located in the opening between the curl 5 and the rear top panel 1 is the draft station 15. This draft station separates two openings 16 and I1. Opening I6 may be used for the syrup dispensing units i 6 and similar containers with hinged tops, to be described later, for syrups for sundaes may be located in opening I1.

Located in the space formed by the upwardly and forwardly inclined flange I, the top back panel I and the rear panel I 2 is the container 18- to receive the syrup dispensing units 6 and the syrup containers located in opening ll.

Container l8 extends the entire length of the syrup rail and is separated from flange M by a heat insulating strip l9 and fastened thereto as by bolts. Similarly it is fastened to curl 5 by heat insulating strip 20. In the bottom of container It is connected a drain 2| to facilitate cleaning.

The container 6' is formed as shown in solid line in Fig. 3 and protuberances 22 are pressed out so as to rest on curl 5 and a break 23, formed in flange l3.

For fastening on the cover 26 of the syrup dispensing units grooves 23 are formed on each side of container 6 and corresponding grooves 24 are formed on flanges 25 of cover 255 so that grooves 24 can be moved into registration with grooves 23 and hold cover 26 firmly in place as shown in Fig. 4. Cover 26 is formed to extend over curl 5, as shown at 2! in Fig. 2, so as to form a continuous contour including the top back panel 1, container cover 26 and the upwardly and forwardly inclined flange 2. The space 28 formed by this extension permits grooves 2t to be moved into and out of registration with grooves 23 in container 6'.

The containers for the syrup for the sundaes are formed the same as containers 6 except that they are preferably not formed as deep. The cover 30,. shown in Fig. 5, is used to cover this container instead of the cover 25 shown in Fig. 2. This cover is in two sections, 3i and 32, the forward part 3! being connected to the rearward part 32 by the piano hinge 33. Formed in flange 34 of the rear section 32 are the grooves 24 which can be moved into registration with grooves 23 in container 6 and retain the rear section 32 firmly in position on container 5'. The forward part of this cover is formed with the inwardly curved notch 36 to form a handle so that the forward part of the cover 3| can be lifted and rotated around piano hinge 33 to the dotted position shown at 3!.

For insulating the syrup rail, I provide a heat insulating material 31 between the rear panel 12 and the container [8 and the heat insulating material 38 between the upwardly and forwardly inclined flange 2 and the container is. For

cooling the syrup rail to prevent fermentation of the syrups, I provide a cooling coil 40 along the forward side of container I8 located as shown in Fig. 2. In my preferred form, I press a strip of stainless steel in the form of a coil 41, shown in Figs. 1 and 2, and seam weld it to the forward part of container I 8 at 42, 43, and 44. To the ends of this coil are connected the

pipes

45 and 46, which are connected to the refrigerating unit in the soda fountain base 41 located under the sinks 48.

Fig. 6 shows an alternate form of my cooling coil. In this form I provide a base strip 48, to which is fastened a strip pressed to form a coil 49 by seam Welding at 50, 5|, and 52. This unit is then located in the same position as shown for coil 4| and the base fastened to container l8, as by brazing.

I have found that by locating my cooling coil so that it imparts the cooling effect directly to the syrup in container 6 by a metal to metal contact that I can maintain the syrup at the necessary temperature without maintaining the area 53 at a greatly reduced temperature such as is customary practice where the cooling coil is located in space 53. This eliminates the tendency for the top rear top panel 1 to sweat due to the conduction of heat along flanges i3 and I4.

Having described my invention, 1 claim:

1. A syrup rail for a soda fountain cabinet comprising an upwardly and forwardly inclined flange projecting above the top of the forward part of said cabinet, said flange terminating at its top in a rearwardly and downwardly formed curl, a top back panel located rearwardly and above said curl providing an elongated forwardly inclined opening between said top back panel and said curl, a downwardly rojecting flange on the forward side of said to back panel, an elongated container located below said opening having its rear upper edge connected to said second mentioned flange and its forward upper edge connected to said curl, a back panel for said syrup rail connected to the rear of said top back panel and extending downwardly therefrom, an insulating material between said back panel and the rear side of said elongated container and between the forward side of said elongated container and said upwardly and forwardly inclined flange.

2. A syrup rail for a soda fountain cabinet comprising an upwardly and forwardly inclined flange projected above the top of the cabinet, said flange terminating at its top in a rearwardly and downwardly formed curl, a top back panel located rearwardly and above said curl providing an elongated forwardly inclined opening between said top back panel and said curl, a downwardly projecting flange on the forward side of said top back panel, an elongated container for receiving syrup dispensing units located below said o ening having a rear edge disposed adjacent to the top back panel and a forward edge disposed adjacent to said curl, means for chilling the container so as to cool the contents of syrup dispensing units disposed therein, and heat insulating means interposed between and separating the container from said curl and said top back panel preventing sweating of said curl and parts of the cabinet adjacent thereto and of said to back panel due to chilling of said container.

3. A syrup rail for a soda-fountain cabinet having a container therein provided with a metallic downwardly and rearwardly sloping'fiat wall forming a support for a syrup container, a syrup container having a flat forward wall lying against and supported by the sloping wall of said first container, the front wall of said syrup container bearing against and having metal-to-metal contact over substantially its entire area with the sloping wall of said first container, means in heatexchange relation with the lower portion of the sloping wall of said first container forming conduits for liquid refrigerant and adapted to chill the contents of the syru container supported by said wall, and means insulating said first container from adjacent parts of the cabinet and preventing said adjacent parts from sweating due to chilling of said container by said refrigerant.
