The special arrangements made in the design of this instrument make it very suitable for use in places exposed to damp or rough usage, such as railway and ship yards, factories, traction routes and all other out-door installations.

Fine quality Cast-Iron case made in three main portions-the body, the inner door, and the outer door-finished in black enamel.

The body contains the terminals, lightning arrester, induction coil, generator and ringer movement with a hammer which operates through a gland to the outside where the gongs are fitted and protected so as not to deaden the sound; also a separate compartment is provided for 2 dry cells and fitted with a removable cover at the side. The maximum dimensions of each cell are
2.25 x 2.25 x 5.5 inches.

The inner door, when closed, renders the body watertight and only exposes the micro-telephone, switch hook and generator handle, which are similarly protected when the outer door is closed.

The micro-telephone is firmly held on the switch hook by means of projecting pads which bear on the transmitter case, thus making the switch hook more reliable, as it is not entirely dependent on gravity.

Fitted with interchangeable inset type transmitter, patent hygienic mouthpiece, and waterproof cord protected from mechanical damage by a flexible metallic tube.

Two holes are provided on the top of the case for leading in the external wires, and are so formed that they may be hermetically sealed with a suitable compound after the wires are lead in: also the top portion of each hole is threaded so that screwed tubing may be used to protect the wires.

Generator - 5-magnet Ringer 2000 ohms
Dry cells are included
