SVJITC'T-EING SYSTEI I.

Application filed March 38, 1928, Serial No. 266,040, and in This invention relates to an arrangement of switching connections whereby it is pos sible, even with more than two collector rail or feeder terns to connect any two teins by means of'a single coupling switch.

This is attained in accordance with the invention by providing a number of separating switches in groups in front of and behind a coupling switch, the number of separating switches in each group being one less than the number of feeder systems.

in the accompanying drawing, Fig. 1 a diagrammatic representation of a switching system embodying this invent on, while Fig. 2 is a view similar to Fig. 1 showing a greater number of feeder systems.

Referring to the drawing, in Fig. 1 the invention is shown as applied to three collector rail or feeder systems 1, 2, and Separating switches =1, 5, G and 7 are provided, these separating switches being arranged in two groups of two switches each. The separating switches 42 and 5 form one group which lies in front of a coupling switch 8, shown as a circuit breaker, and the separating switches 6 and 7 form the other group which lies behind the coupling switch 8. The switches 41 and 5 control an electrical connection from one side of the coupling switch 8 to the feeder system 1 and 2, the switch 1 controlling the connection with the feeder system 1 and the switch 5 controlling the connection. with the feeder system 2. in a similar manner the switches (3 and 7 control an electrical connection from the opposite side of the switch 8 to the feeder systems 2 and 3, the switch (3 controlling the connection with the feeder system 2 and the switch 7 controlling the connection with the feeder system 3. The switches el; and 5 are interlocked as, for example, by means of a mechanical connection 9 so that on y one switch can be closed and'the switches G and 7 are similarly interlocked by means of a mechanical connection 10.

In Fig. 2, four feeder systems 11, 12, 13 and 14 are shown and in this case the separating switches are divided into two groups of three each. The separating switches 15, 16 and 17 constituting one group, control connections respectively with the feeder systems 11, 12 and 13 on one side of the coupling switch 18, while the separating switches 19, 20 and 21 on the opposite side of the switch 18 control the connections with the feeder systems 12, 13 and 14; respectively. As in the arrangement. of Fig. 1 the separating switches in each group are interlocked so that only one can be closed at any one time.

In both embodiments, by switching in the coupling switches 8 or 18 any two collector rail or feeder systems can be connected together in accordance with which separating switches are closed. Thus for example, in accordance with the arrangement shown Fig. 1 the feeder systems 1 and 2 are connected. together when the coupling switch 8 is closed, while in the arrangement shown in Fig. 2 the feeder systems 11 and 12 are connected together when the switch 18 is closed.

The coupling switches 8 and 18 are preferably arranged to open and close the circuit under power, wherea the separating switches may be simple disconnecting switches not designed to open or close the circuit under power. The system thus has the adyantage that any two of plurality of feedra' systems may be connected or disconnected and only a single switch need be provided which will open and close the circuit under power.

lVhat we claim as no i and desire to secure by Letters Patent of the United States is:

1. An electric interconnecting switching system for a plurality of feeder systems comprising a coupling switch, two groups of dis connecting switches electrically connected to opposite sides of said coupling switch, electrical connections between said disconmwrt- 1E g switches and selected feeder systems respectively so that any two of said feeder systems may be interconnected through said coupling switch and an appropriate disconnecting switch of each group.

2.1111 electric interconnecting switching system for a plurality of feeder systems comprising a coupling switch, two groups of disconnecting switches electrically connected to opposite sides of said coupling switch, each group comprising one less switch than the number of feeder systems, and electrical connections between said disconnecting switches and selected feeder systems respectively so that any two of said feeder systems may be intercoimected through said coupling switch and an appropriate disconnecting switch of each group.

3. An electric interconnecting switching system for a plurality of feeder systems comprising a coupling switch, two groups of disconnecting switches electrically connected to opposite sides of said coupling switch, each group comprising one less switch than the number of feeder systems, and electrical connections between said disconnecting switches and selected feeder systems respectively so that any two of said feeder systems may be interconnected through said coupling switch and an appropriate disconnecting switchof each group, and interlocking means 10 between the disconnecting switches in each group whereby only one of the switches in each group can be closed at one time.

In witness whereof, we have hereunto set our hands this Hth day of hIarch, 1928.
