PEREZ REFRIGERATOR COMPRESSOR STAND 2 Sheets-Sheet 2 Dec. 20, 1955 Filed June 14, 1954 United States Patent REFRIGERATOR COMPRESSOR STAND Arthur Perez, Niles, Mich, assignor to Tyler Refrigeration Corporation, Niles, Mich., a corporation of Michigan Application June 14, 1954, Serial No. 436,373

Claims. (Cl. 62-115) This invention relates to a refrigerator compressor stand which is a structure to support the compressor and other refrigeration machinery used to cool refrigerators and it is particularly intended for use with commercial refrigerators where multiple units are used and serviced by multiple refrigeration equipment located at a central location.

This refrigeration machinery is quite heavy and is frequently located in places that are rather inaccessible to move into. Also, the machinery must be serviced frequently.

The present invention provides a stand having shelves upon which the refrigerating mechanism is mounted in a way that the different parts of each unit can be conveniently and systematically connected together for operation with a minimum of piping and electric Wiring. The parts of the mechanism are also arranged so that they are readily accessible for servicing. The shelves of the stand with the mechanism mounted thereon may be easily disconnected from the frame work so that they can be carried one at a time to their desired location which is desirable because of their weight and inaccessibility of the location. Also, the frame work can be disassembled so that it can be moved through small passageways.

The invention is hereafter more fully described, reference being had to the accompanying drawings in which,

Fig. l is a perspective view of a stand embodying the invention,

Fig. 2 is a front elevation of the stand showing the refrigerating mechanism mounted thereon, and

Fig. 3 is a transverse section elevational of the same on the line 33 of Fig. 2.

The refrigerating mechanism is shown diagrammatically.

Like reference numbers refer to like parts in all of the figures.

The principal parts of a refrigerating mechanism are the compressor 1 run by the motor 2, usually an electric motor, the condenser 3 and the evaporator (not shown).

The evaporator is located in the refrigerated cabinet but the other parts above enumerated are located outside the cabinet and it is for the accommodation of these parts that the stand of this invention is provided. The stand with the mechanism thereon may be located a considerable distance from the refrigerated cabinet and the condensed refrigerant piped therefrom to the evaporator in the cabinet.

Since this mechanism is electrically operated and controlled there is provided for each unit an electric control box 4 in which the usual switches, fuses, and other electrical devices and connections are located.

The stand comprises two end members 5 which may be made of sheet metal. These end members are narrow at the base and considerably widened at the top, having their forward edges inclined upwardly. A for- "ice wardly extending arm 6 is attached to each end member by suitable means and each arm 6 has a front leg 7 attached to it. A channel supporting bar 8 is attached to the upper end of each end member 5 and extends forwardly therefrom.

Two upper cross members 9 extend between the ends 5 and have their ends supported on the bars 8 to which they are disconnectably attached as by bolts. Two similar cross members 10 extend between the arms 6 which support them and to which they are disconnectably attached. The forward cross member 10 is in a vertical plane somewhat forwardly from the upper front cross member 9. A cross bar 11 extends between the end members 5 in a mid vertical position and is discon nectably attached thereto. Diagonal brace bars 12 extend between the ends 5 and are disconnectably attached thereto.

The shelving herein shown is designed to accommodate four compressor units although it can be designed for more or less. The compressors 1 and motors 2 are mounted on shelves comprising channel members 13 which are supported on the cross members 9 and 10 and plates 14 which are part of the motor or compressor, lie upon the channel members 13.

The arms 6, bars 8, cross members 9 and 10, and channel members 13 have slots 6a, 8a, 9a, 10a, and 13a for the passage of bolts by means of which the various members may be connected together in various adjusted positions so that different parts of the units of difierent sizes may be accommodated thereon.

When mounted on the shelving, the different parts of each unit are connected together in operative order. The motors 2 are electrically wired to the control boxes 4 through conduits 15. The motors are connected to drive the compressors 1 by belts 16. The compressors 1 are connected to the condensers 3 by tubing 17. The condensers 3 are connected to water pipes 18 and 19 by piping 20 and 21.

The condensers 3, which are for the purpose of water cooling the compressed refrigerant which is pumped into them by the compressors, are suspended under the cross members 10 as by brackets 22 attached to the channel members 13. They are elongated bodies having Water tubes in their interiors and these must be cleaned frequently. To facilitate this cleaning, the condensers have removable heads and they are mounted with these heads at the front of the shelving so that a cleaning rod may be thrust into the tubes to clean them.

For servicing the mechanism on the upper shelf, the mechanic can stand on the front cross member 10 of the lower shelf which is located forwardly of the upper shelf. This obviates the necessity of a ladder or stool for this purpose.

The entire assembly is fabricated so that for ease of shipping and handling, the shelves with the units attached may be dismantled from the end assemblies. Also, the cross bar 11 with the electric control boxes 4 may be disconnected and handled separately. The diagonal brace bars 12 can be separated from the end members so that the entire assembly can be moved in relatively small and light weight parts.

Grouping of all of the condensers 3 close together is considered a desirable factor since it provides a minimum of plumbing which reduces installation cost.

The invention is defined by the appended claims which are to be considered comprehensive of all forms coming Within their scope.

I claim:

1. In combination, a stand, a plurality of refrigerator compressor systems mounted thereon, each system ineluding an electric motor, a compressor, a condenser,

water cooling means for the condenser, electric control mechanism for operating the motor, and electric safety devices, the compressor and condenser of each system being interconnected, all of the electric mechanisms, in-

cluding the motor, of each system being interconnected,

a single electric supply conductor connected with the electric mechanisms of all of said plurality of systems and the water cooling means of the condensers of all of said systems being connected to a common single water supply conductor.

2. The elements of claim 1 in which said stand has a front and an upper and a lower shelf, parts of some of said compressor systems being located on each shelf, said lower shelf extending forwardly of said upper shelf thereby providing a foot support for an operator when servicing the compressor systems on the upper shelf.
