CALL OFFICE SIGNS
Scope of Instruction
This instruction deals with all signs employed to advertise and indicate the position of
Public Telephone Call Offices, and also describes signs suitable for fitting internally or
externally on a subscriber's premises where the subscriber desires a sign to advertise the
availability of his telephone for public use.
The Ministry of works and Buildings is responsible for the provision and maintenance of
all signs at Class 1 Crown offices.
The Engineering Dept
Is responsible for the provision and renewal of signs and brackets for signs at all other
Post Offices, all call offices not on P.O. premises, and for subscribers' premises where
the subscriber has asked for a sign. Subsequent to the initial provision and renewal of
signs, the Head Postmaster will be responsible for maintenance.
Issued by the T.M., for the provision of call-office circuits or for signs on subscribers
premises, should give particulars of the number of signs to be provided and the type and
precise location of each sign.
The traffic staff are responsible for obtaining permission for the erection and should do
so before the Advice Note is issued.
Signs on subscribers premises
The position of each sign and the method of fitting should be discussed with the
subscriber before the work is commenced and, provided that a secure fixing is obtainable
and due prominence is given to the sign, the subscribers reasonable requirements should be
Signs on telegraph poles
Signs will be fitted by the Engineering Dept to poles designated by the traffic staff,
provided there is no engineering objection, e.g., a more suitable site is available or
that the local authorities may object to the proposed site.
Where the pole in question is situated on a public highway, the consent of the local
authority to the attachment of the sign will not normally be sought. where, however, it is
known that the local authority desires to be advised of such attachments, the Area Engr.
will, before the work is put in hand, ascertain that the Surveyor to the local authority
does not object.
Signs on kiosks and cabinets
Suitable signs, where necessary, have been embodied in the structural design of kiosks and
cabinets, and signs other than those of standard type should not be fitted.
For fixing to the exterior walls or buildings, on telegraph poles, tramway or street lamp
standards, etc, and for fitting inside subscriber's premises are detailed below.

DESCRIPTION OF FIXINGS
Signs, Call-Office, No 1, 1A and 5
Are fixed to walls by means of Brackets,Sign,No1,when
fixing the bracket particular care must be exercised to ensure that the holes for the
screws are well plugged and the plate of the bracket is fixed firmly to the wall. Where it
is found that secure fixing cannot be obtained on the wall direct, a batten should be fixed
to the wall and the bracket should then be firmly fixed to the batten. Sign, Call Office,
No 20 is suspended from a Bracket Sign, No 1B, which
is attached to poles and standards by means of a strip of 14in. x 1in. mild steel. The
steel strip should be bent round the pole or standard and terminated in the block of the
bracket. In this termination, the ends of the steel strip are turned back against the nut
which holds the tightening screw. If the pole or standard tapers sharply, it may be found
necessary to fit a narrow compensating strip in the upper edge of the main strip.
Signs, Call Office, No 2
Are fitted in position by means of wall spikes which hold the sign flat against the wall.
Sign, Call Office, No 3
Does not require brackets for fitting. Fixing is effected by nails or screws, driven
through a flange on the sign. The flange is part of the main plate of the sign bent at
right angles. This type of sign is used at railway stations and where a Sign, Call Office,
No 1 is too large.
Signs, Call Office, Nos. 6, 7, 8, 8A, 8B, 8C and 8D
Are used in conjunction with Signs, Call Office, Nos. 1 and 12 and 12A. They are suspended
from these signs by means of S type hooks. Eyeletted holes are made in each of the signs
to accommodate the hooks.
Sign, Call Office, No 10
Is framed in oak and used inside subscribers, premises. Eyeletted holes are provided in
the frame, to allow the sign to be suspended in a convenient and prominent position.
Signs, Call Office, No 12 and 12A
Are self-contained signs for fixing to wooden poles. Two curved flanges are provided in
the sign as a means of fixing the sign to the poles. A hole and a slot exist in each
flange, the slot accommodating a coach screw and the hole a No 23 - 2 in. wood screw.
prior to erecting the sign, the two coach screws are driven into the pole for a length
approximately within half an inch of the head of the screw. The slots in the flanges are
then passed over the coach screws underneath the head. This will afford a temporary
support for the sign while the coach screws are driven right home. The sign is secured
firmly in position by means of the wood screws, driven through the holes in the flanges.
Signs, Call Office, Nos. 16 and 16A
Are provided primarily for use in large stores and similar premises. The sign is provided
with two screw-eyes so that the sign can be suspended in a convenient and prominent
