Claim 6

In combination with a transformer tank having high voltage and low voltage terminals extending from separate portions of a side wall, cover means comprising a high voltage and a low voltage cover alongside each other, each cover having a top, a front and an outside wall, the high voltage cover additionally having a barrier integral therewith between the high voltage and low voltage segments and a water drainage and tamper-resisting channel along its top and front adjacent said barrier, said low voltage cover additionally having a lip interfitting with said channel, the top of each cover being independently hinged to the tank top, each cover having means for independently locking the cover when in a closed position, whereby swinging open of the low voltage cover will permit access to the low voltage terminals from the front and one side of the transformer but will not permit access to the high voltage terminals.

Claim 7

In combination with a transformer tank having high voltage and low voltage terminals extending from separate portions of a side wall, cover means comprising a high voltage and a low voltage cover alongside each other, each cover having a top, a front and an outside wall, the high voltage cover additionally having a barrier integral therewith between the high voltage and low voltage segments and a water drainage and tamper-resisting channel along its top and front adjacent said barrier, said low voltage cover additionally having a lip interfitting with said channel, the top of each cover being independently hinged to the tank top, each cover having means for independently locking the cover when in a closed position, whereby swinging open of the low voltage cover will permit access to the low voltage terminals from the front and one side of the transformer but will not permit access to the high voltage terminals.

Claim 8

The combination according to claim 3, further provided with a hinge stop On each of said low voltage and high voltage covers interengageable with a hinge thereon to prevent removal of these covers, and means accessible only from the inside of the respective covers for removing said stop.

Claim 9

A transformer comprising a tank having a top and a wall of rectangular shape, a set of high voltage terminals on one portion of said wall extending from one side thereof, a set of low voltage terminals on another portion of said wall extending from the other side, a vertical flange on said wall between said sets of terminals, a high voltage cover having a top, front and outside wall, the top being hinged to the top of said tank, a barrier wall on said high voltage cover between said sets of terminals, a sill extending from the lower portion of said tank wall, the high voltage cover being swingable between a closed position interfitting with said sill and tank wall and an open position in which the top is swung back against the tank top, the barrier wall closely overlapping said flange when the high voltage cover is closed, a low voltage cover having a top, front and outside wall, said top being hinged to the top of said tank, the low voltage cover being swingable between a closed position enclosing said low voltage terminals and an open position resting against the top of said tank, and independent interfitting locking means on said sill and the front walls of said two covers, whereby they may be separately locked closed.

Claim 10

A transformer comprising a tank having a top and a wall of rectangular shape, a set of high voltage terminals on one portion of said wall extending from one side thereof, a set of low voltage terminals on another portion of said wall extending from the other side, a vertical flange on said wall between said sets of terminals, a high voltage cover having a top, front and outside wall, the top being hinged to the top of said tank, a barrier wall on said high voltage cover between said sets of terminals, a sill extending from the lower portion of said tank wall, the high voltage cover being swingable between a closed position interfitting with said sill and tank wall and an open position in which the top is swung back against the tank top, the barrier wall closely overlapping said flange when the high voltage cover is closed, a low voltage cover having a top, front and outside wall, said top being hinged to the top of said tank, the low voltage cover being swingable between a closed position enclosing said low voltage terminals and an open position resting against the top of said tank, and independent interfitting locking means on said sill and the front walls of said two covers, whereby they may be separately locked closed.
