405, 504 and 505

Cat No. 404 shown above

MAGNETO TELEPHONE
Wall Pattern

In this well-known instrument, usually referred to as the - "Compact" set, provision is made for the accommodation of two No. 2 dry cells inside the case.  The lower portion forms a separate compartment from that containing the ringer and generator, and the front is hinged to give easy access. The same component parts are employed as in the "Shortphone".  Woodwork is of polished walnut and the instrument is designed throughout to give lasting service with a minimum of maintenance.

With the exception of the No. 301 type, which is wired for use on series circuits, all "Compact" sets listed below are ordinary bridging instruments.  The "sure-ring" feature incorporated in sets Nos. 404 and 405 is obtained by introducing a condenser in series with the receiver so as to ensure that, if the receiver is left off the hook, the hell is not short-circuited and can he rung.

To simplify packing and storage and to prevent damage in transit, the transmitter, receiver, switch hook and generator handle are detached prior to shipment and packed in the battery compartment.

Dry cells are supplied only when specially ordered.
