doors were continued in use and are still being used. In
replacing the 5 elevators in 1942, the glass-panelled hoistway
doors on those 5 elevators were replaced with solid panelled
doors.

In 1941, the old freight elevator was modernized and in 1958
it was converted to operate with or without an attendant.

After discontinuation of the generation of 25-cycle alterna-
ting and direct current electrical energy at the Capitol Power
Plant in 1950-1951 for the Capitol group of buildings and the
procurement thereafter of 60-cycle alternating current from
the local Public Utility, the electrical systems in all of the
Capitol Buildings were converted from 25-cycle alternating
and direct current to 60-cycle alternating current. As a
part of this program, in 1953 new motor generator sets and
starters designed for 60-cycle alternating current operation
were installed on all 12 elevators then in operation in the
Cannon Building.

Other than the work done in 1953, no major overhaul work
has been done since replacement of the 11 passenger elevators
in 1934-1942. They have been kept in operation in the
interim years through complete annual inspection and pre-
ventive maintenance, replacement and repair parts being
available from the Otis Elevator Company.

Under the funds requested for 1974, it is proposed to con-
vert the 11 passenger elevators from manual to selective-
collective operation, permitting operation with or without
an attendant, to make modifications to existing equipment
and replacements of items as shown by the following

Modifications to this equipment will be made, as required,
including replacement of reactance type brush holders and
brushes; also replacement of brake parts, as required,
including bronze tube, magnet core, brake arm levers, pins
and pivots and brake switch for each brake magnet.

New equipment to be provided and installed:

Controller and selector

Safety governor

Machine room and hoistway wiring

Car frame, safety and rolling guides

Elevator cabs and car entrance doors

Power door operators

Door protective devices

Car operating devices

Top-of-car operating device

Interlocks and emergency door closing devices

Top and bottom "Access Switches"

Landing call buttons

Two-to-one counterweight sheave, complete with

roller bearings and new crosshead plates

Fire emergency operation; emergency power

operation

If the funds requested for this program are allowed, when
the work proposed to be done is completed all of the
passenger elevators in the Cannon Building will then conform
to present-day elevator code requirements and will provide
emergency fire service and automatic emergency power
operation.

1/ In addition to the total of $8,858,000 shown on page 14,

an additional amount of $40,000 is required to cover the

cost of 1/1/73 "White Collar" pay raise in F.Y. 1974, to be transmitted at a later date, as per Budget Bulletin 73-4, dated 1/26/73.
