Application filed May 4,

Our invention relates to switches and switchboard panels and it relates particularly to switching devices for elatively high-voltage circuits.

The object of our invention is to provide a switching device, of the above-designated character, which may be constructed 0t such standard parts as are employed in ordinary insulating and switchboard constructions and in such manner as to provide a structure that may be adapted to a series of switches de signed for a large range of voltage values by merely changing certain minor portions of the apparatus.

A further object of our invention is to provide a switchboard panel which may be constructed of structural iron and the like and the design ofwhich is readily adaptable to switches of various capacities and to switches of diflerent voltages.

Heretofore, it has been customary, in the construction of panels of the above-indicated character, to employ base members of insulating material on which the various switching devices are mounted.

In accordance with our invention, we provide a panel constructed of structural iron on which the various switch members are mounted and from which they are insulated by means of standard insulating structures of the kinds employed in various other forms of apparatus. Furthermore, our structure is of such flexible design that it may be arranged to accommodate any one of a relatively large series of switch designs having difl'erent numbers of contactors and arranged for wide ranges of voltage and current values.

Fig. 1 of the accompanying drawing is a front elevational view of a switching device constructed in accordance with our invention; and Fig. 2 is a side elevational view of the device shown in Fig. 1.

The drawings illustrate a panel 1, or frame, of structural iron on which a pair of auxiliary panels 2 and 3 are mounted and insulated therefrom by insulators 4 and 5. A stationary switch contact member 6 is mounted on each of the auxiliary panels 2 and 3, and a movable contact member 7 is actuated into and out of engagement with each of the stationary contact members 6 by means of an actuating device 8.

The structural framework 1 comprises a 1920. Serial No. 373,?92.

pair of upright channel members 9 and 10 that are mounted on a base member 11 oi channel shape and are connected by a top angle iron 12 and by an intermediate plate 13.

The framework 1 should be of a construction that will permit of co-ordination of aseries of like panel members in such manner as to compose a complete switchboard.

Each of the auxiliary panels and 3 is of insulating material and the panels are mounted on insulators i and 5 in order to eiiectively insulate the electrical devices that are mounted on the auxiliary panels from the structural framework and to dispose the panels in spaced relation upon the framework 1.

An arc-blowout shield 14, which is mounted on each of the panels 2 and 3, comprises a blowout coil 15 and magnetic side-plate members 16 therefor. One terminal of each of the blowout coils 15 is connected to a terminal member 1? by means of a bolt 18 and a conductor 19. The remaining terminal of each of the coils 15 is connected to the corresponding stationary contact member Each of the stationary contact members 6 is secured in place by means of a series of bolts 20 that serve, also, to secure the auxiliary panels 2 and 3 to the insulators 5.

The movable portion of each of the switch mechanisms embodies a contact member 7 that is pivotally mounted on a bracket member 24 by means of a pin 22 and is yieldingly held in position by a spring 23, in a familiar manner. The contact member 7 is electrically connected to a terminal member 25 through a bolt 26 and a flexible conductor 27. The several bolts 26 extend through insulators 28 that are respectively mounted on the channel members 9 and 10. The bracket members 24s are mounted on rods 29 of insulating material, such, for example,

as micarta rods, which are clamped to a,

transverse rod 30 by means of respective sets of clamping jaws 31.

The actuating mechanism 8 comprises a core member 32, two coils 33, which are mounted on the respective legs of the core member 32, and an armature member 34. The armature member 3 1 is supported by an arm that is clamped to the transverse rod 30. Bearing members 36 and 37, which are mounted on a base member 38, constitute supports for the transverse rod 30. lhe base member 38 supports the core mem ber 32 of the eleetroinagnet.

An additional panel 39, preferably of insulating material, is mounted on the lugs l of the base member 38 and is secured to the frame 1 by means 01" the bolts ll.

The panel 39 constitutes an insulating base on which any auxiliary apparatus, such, tor instance, as relays, meters and the lilce, may be mounted in order to complete a control unit that embodies the relatively high-voltage switching members.

The trame 1 may be maintained in an up right position by a depending leg 42 that connected, at one end, to the cross menn ber l8 and, at other end, to the floor.

The partici ar uti y of the switching device hereinbe'tore defnibed will be appre ciated when it is pointed out that the insulating members l a l are of a type fie quently employed for odier purposes in electrical install-mini and which may be procured tor a relatively large series of voltage values, and that the voltage for which the switch is to he used determines the type of insulator support to be en'iployed.

It will be understood that, by a mere change of the insulating members l, 5 and 2% and by the use of insulating rod of .-'ving le ths, a switching device may be provided ror any desired voltage without cumloying other than a. standard series of panel nicn'ibers or frame members. Another item of importance is the fact that the actuating mechanism 8 is not insulated -irom the frame work anc, therefore, is not subjected to relatively arge values of voltage, as is the case in such structures as have heretofore been provided.

The required change in the length oi? the insulating rods 29 may be compensated -for by moving the base member 38 upwa 'dly or downwardly in accordance with the position necessary to provide accurate coaction between the movable contact members 7 and the stationary contact members 6.
