CALL-OFFICE INSTALLATIONS
Provision of Kiosks No. 3

GENERAL
1. Introduction
The "Kiosk No. 6" is standard for call offices and will be provided for all future installations, except in certain localities where Public Bodies object to the standard kiosk. In these circumstances, "Kiosks No. 3" will be provided exceptionally, and the procedure to be followed is outlined in C3904; C1001 contains information relating to kiosks generally.

2. Scope of Instruction
This Instruction is re-issued as a guide for the erection of "Kiosks No. 3" erected under the exceptional circumstances referred to in paragraph 1.  A synopsis of the matters dealt with is as follows:-
 

General design of "Kiosks No. 3" Paragraphs 3 and 4
Earthing arrangements Paragraph 14
Erection details common to both types of "Kiosk No. 3" Paragraph 8
Erection details particular to "Kiosk No. 3, Mark 234" Paragraph 15
Erection details particular to "Kiosk No. 3, Mark 2" Paragraph 41
Leading-in of E.L. lighting supply and telephone leads (general) Paragraph 5
Leading-in arrangements applicable to "Kiosk No. 3, Mark 234" Paragraph 36
Leading-in arrangements applicable to "Kiosk No. 3, Mark 2" Paragraph 50


3. General design of "Kiosk No. 3."
There are two types of "Kiosk No. 3," viz., "Kiosk No. 3 (Mark 234) " and "Kiosk No. 3 (Mark 2)". The kiosk is of concrete construction and its general design is illustrated by Fig. 1. The overall dimensions of the Mark 234 kiosk are 8 ft. 7.5 in. by 3 ft. 1 in. by 3 ft. 1 in., whilst those for the Mark 2 type are 8ft. 7.5 in. by 3ft. 2in. by 3ft. 2in.

4. Variants
Both types of kiosks are provided with doors hinged on the right or left, as required, and, as it is frequently desirable that the door should open on the right or left side adjacent to the back, four variations of the kiosk have been provided as follows :-
"Kiosk No. 3A" (which has the door hinged on the left and fitted opposite the back panel)
"Kiosk No. 3B" (which has the door hinged on the right and fitted opposite the back panel)
"Kiosk No. 3C" (which has the door hinged on the left and fitted on the left side)
"Kiosk No. 3D" (which has the door hinged on the right and fitted on the right side).

5. Leading-in arrangements. Underground
"Kiosks No. 3" are specially designed for an underground lead-in of the telephone and electric-lighting leads, in order to :-
(a) preserve the artistic appearance of the kiosk because of the nature of the roof assembly, and
(b) to minimize risk of unauthorized interference with the leads.

6. Leading-in arrangements. Overhead
Leading-in from overhead will only be resorted to when service from an underground cable route is impracticable. As a general rule, the final span should terminate on a pole or wall-bracket in the immediate vicinity of the kiosk, the leads being brought underground from the terminating point to the kiosk. This method of leading-in must always be adopted when, for the final span, a road crossing of open wires would otherwise have to be erected or where the kiosk is situated in a busy thoroughfare. On "Kiosks No. 3 (Mark 234)" the leading-in cable is led to a" Bracket No. 5 " (modified) with a "Clamp, Eccentric," see paragraph 37, whilst "Brackets No. 18" have been introduced for use on "Kiosks No. 3 (Mark 2)," as described in paragraph 51 of this Instruction.

7. When leading-in from open wires is adopted, the final span must not exceed 25 yards in length, and great care must be exercised to ensure that this span cannot in any way be regarded as an obstruction.

8. Erection details common to both types of "Kiosk No. 3"
The following instructions are common to both types of "Kiosk No. 3" and are issued for guidance in their erection; they should be adhered to in principle, although local conditions may necessitate departures there from in matters of detail.

9. Necessity for care in the handling and carrying of sections
The back and sides should be handled on edge, and on no account carried or stored fiat; sacking or similar protective material should be laid on the ground under the corners and edges of the sections, to avoid damage.

10. The base is provided with grooves into which the back and side panels are to be fitted and cemented in. All edges, grooves, etc. which are to be cemented, must be lightly brushed with boiled linseed oil before the sections are placed in position.

11. Preparation of site and provision of foundation
Before placing the base in position, the site should be made firm and level. On unmade ground of a generally level character, an "A" quality concrete (see LINES, Underground, A3501) foundation of a uniform depth of from 4 in. to 6 in. should be provided to support the base, but on pavement, the base should be bedded on Portland cement mortar and left perfectly level. A concrete foundation of the same description is also necessary, to provide a horizontal base, when the site chosen is on a slope. The foundation should be sunk into the slope and it should be of uniform depth. When necessary, a channel should also be provided on the upper side of the foundation, to deflect rain water from the kiosk.

12. If the kiosk is to be erected on ground having a considerable slope, special consideration should be given to the position of the door in relation to the slope, and, where the door would otherwise be considerably higher than the ordinary ground level, the depth to which the concrete foundation is sunk into the slope should be sufficient to make the height of the step into the kiosk reasonably moderate.

13. When a concrete foundation is necessary, it should be put in and the conduits, etc. for underground services laid before any part of the kiosk is taken to the site. When laid, it should be protected from the action of frost, shielded from too-rapid drying by exposure to sun or wind, and guarded for at least 48 hours, to ensure that it will set thoroughly before erection is commenced.

14. Earthing arrangements
Earth electrodes should be provided and the arrangements for earthing the telephone and electric-lighting fittings will be described in an E.I. which will shortly be issued in the PROTECTION, General, S Section.

15. General description
The kiosk comprises 10 parts, viz.:-
1 x Base
1 x Wooden door, with glass panels
1 x Floor slab
1 x Back panel
1 x Transom frame
2 x Side panels
1 x Transom
1 x Iron door frame
1 x Roof

Screws and bolts for assembling are also included. The weight of the 10 parts is approximately 15 cwt. A supply of grouting will be required, and, in this connexion, a quantity of "Earle's mastic cement, 'A' quality, grey" should be obtained locally; the cement should be mixed with boiled linseed oil to approximately the consistency of putty. The resulting mixture is somewhat slower in setting than ordinary cement grouting, but is more adhesive and easier to handle.

16. Order of erection of various kiosk sections
The foundation having been prepared, the sections should be erected in the following order and in accordance with subsequent instructions:-
Base
Panel opposite the door
2 Panels adjacent to door
Door frame
Floor slab
Transom frame
Transom
Roof
Door

17. Base
Lay the base on a piece of timber, which has been placed previously across the site. The base should then be adjusted to its correct position so that the slots provided for underground telephone and electric-light service leads (see paragraph 39) are adjacent to the position to be occupied by the panel opposite the door, and the piece of timber should be removed. Portland cement should be filled in all round the base at the ground line, trowelled off and left smooth and clean, but this should not be done to bases bedded on Portland cement mortar before the mortar has set. The grooves in the base should be filled in with a thin layer of grouting compound before the back and side panels are erected.

18. Panel opposite the door
The back or side panel, according to the type of kiosk, should be raised carefully and lifted into the appropriate groove in the base (see paragraph 3).

19. Panels adjacent to door
Raise the panels and carefully lift into the appropriate groove in the base.

20. When the side and back panels have been erected they should be screwed together, using the screws, nuts, and washers supplied with the kiosk, but the screws should be left slightly loose so that they may be tightened up later.

21. Door frame
The door and fittings should be detached from the door frame, which should next be fitted and also lightly screwed up.

22. The position of the back and side panels in the grooves may need adjustment, as the width of the grooves allows a certain amount of play.

23. Floor slab
The floor slab should then be placed in position. It must lie in a central position, 0.25in. clear all round, with a slight slope towards the door, care being taken to ensure that it will not prevent the door closing properly, and should always be inserted so that the slots provided for telephone and electric-service leads are adjacent to the back or blank panel, and register with the corresponding slots in the base, see paragraph 15.

24. Scaffolding to facilitate erection of uppermost sections
The structure is now ready for erection of the uppermost sections, but, before this work is proceeded with and to facilitate it, a light scaffold about 4 ft. high should be erected round the kiosk.

25. The transom frame should then be fitted and screwed to the iron door frame. The panel opposite the door should next be adjusted and screwed to the transom frame.

26. Before any further work is done, the interstices between the floor slab and base and the panels inside the kiosk, and between the base and the panels outside, also the vertical joints between the panels and between the panels and the door frame, should be filled with grouting material (see paragraph 15). At the foot of the panels, the grouting should be finished off at the level of the floor slab inside the kiosk and at the level of the base outside.

27. While the grouting in the vertical joints is still wet, the screws, nuts and washers holding the panels and door frame together should be tightened up evenly and the whole structure made rigid.

28. The transom frame should then be screwed to the sides.

29. When the grout has commenced to set, any excess of grouting material extruded from the joints as the result of tightening up the screws must be scraped off and all the holes in which the screw heads are visible should be stopped with grout flush with the surrounding surface.

30. Transom
Before the transom is fitted, the roof should be tried on it, as the latter may be found to fit best in one particular way. When the best way has been found, both the transom and the roof should be so marked that the marks will coincide when the two sections are finally erected.

31. A thin layer of the grouting material should be laid on the top edges of the back and side panels before the transom is fitted. The transom should then be placed on the transom frame and a thin bed of the grouting mortar should be laid on the corners of the transom to receive and fix the roof.

32. Roof
Before fitting the roof a piece of timber, on which the roof can be rested temporarily, should be placed across the transom to prevent the edges of the roof and transom from damage while the former is being suitably placed. The timber may then be withdrawn and the roof lowered into position.

33. Door
The door should next be placed in position. It should be wedged up as high as possible while the hinges are screwed up. Before the restraining straps and door spring are fitted, the door should be tested to ensure that it swings freely. The door-closing spring, when fitted, should be adjusted to function properly.

34. Any slight damage sustained by the kiosk during transport or erection should finally be made good with grouting material (see para. 15). Ordinary cement should not be used for this purpose.

35. Signs
Four opal signs - "Glasses No. 25" - should be fitted in all cases.

36. Leading-in - General
The general principles of leading in to kiosks are detailed in paragraph 5; the method of applying them on a "Kiosk No. 3 (Mark 234)" is described in paragraphs 45-47.

37. Leading-in - Overhead
When it is essential to terminate open wires direct on a kiosk, the following method should be adopted. The sides of the "Bracket No.. 5" should be shortened to 7 in., by means of a hack-saw. The altered bracket should then be bolted to one corner of the kiosk immediately below the roof, preferably at the back, by means of two ( in. by 21 in. bolts, which should be obtained by local purchase. The two holes in the kiosk to take the bolts should not be cut with a chisel but should be drilled with a hand drill, to ensure that the framework of the kiosk is not fractured. A 11 in. washer should be placed over the bolt thread inside the kiosk, to give a good bearing surface. A "Clamp, Eccentric" should be fitted in the bracket, as described in LINES, Overhead, E 3101, and "Cable, I.R.V., Braided and Compounded" from the pole or house-fixing should be passed through the clamp, through the ventilator on the kiosk, and terminated on the protector.

38 Special attention must also be given to ensure that the four corners of the roof are properly secured by grouting. When this method of leading-in is adopted, the slots in the floor slab and base should be filled-in and cemented over.

39. Leading-in - Underground.
(a) Protection for leads
Lengths of galvanized iron conduit are provided for protecting the telephone and electric-lighting leads, when these are to be brought into the kiosk from underground. The conduit should be run upwards behind the wallboard. The length provided for the telephone leads should be sufficiently long to enable them to be led to the protector or direct to the telephone, as required, see (c). The conduit for the electric-lighting leads should be carried further, as required, to the electric-lighting control apparatus.

(b) Method of securing conduit
Wooden plugs are inserted in the back panel in positions where, if the floor-slab and back panel have been fitted properly, the plugs should be immediately above the slots in the back panel through which the telephone leads are brought into the kiosk (see paragraph 23). These plugs are to be used for fixing the saddles, which are provided for securing the conduit.

(c) The telephone leads should enter the kiosk through the right-hand slot, as viewed from the inside of the kiosk, thence they should be led up through the conduit behind the wallboard. From the point where they emerge from the conduit, they should be run adjacent to the batten on the wallboard to the protector (if fitted) and, thence, behind the wallboard to the telephone, or direct to the telephone, if a protector is not required.

(d) The electric-supply leads must always be led into the kiosk from underground by means of armoured cable or cable in conduit, and should enter through the left-hand slot, as viewed from the inside of the kiosk. Electric lighting should be provided as indicated in POWER, Lighting, A 3101.
40. Items to be requisitioned separately.—The following stores are necessary in connexion with the provision of each kiosk and should be requisitioned separately; 4 "Glasses No. 25" (see para. 35); "Conduit No. 2A," as required; "Conduit Saddles No. 2A" as required; and equipment detailed in D 3001. In addition, a supply of grouting will be required and should be purchased locally, see paragraph 15.
 

KIOSKS NO. 3 (MARK 2)

41. General description
This type of kiosk differs from the "Mark 234" type in certain minor details. The main distinguishing feature is that the panels and transom of the "Mark 2 "type are in one piece, whereas the panels, transom frame and transom are separate items in the "Mark 234" type. The "Mark 2" type of kiosk comprises the following parts:-
1 x Base
1 x Iron door frame
1 x Floor slab
1 x Wooden-framed door, with glass panels
1 x Back panel
2 x Side panels
1 x Transom panel
1 x Roof

Screws and bolts for assembling are also included. The weight of the 9 parts is approximately 15 cwt. Grouting material which will be required, should be obtained as indicated in paragraph 15.

42. Erection
The various parts should be erected in accordance with paragraphs 16 to 35, with the exception of the operations to which special attention is drawn in paragraphs 43 to 54.

43. Order of erection of various parts
The transom frame included in "Kiosk No. 3" (Mark 234) is eliminated in "Kiosks No. 3 (Mark 2)." The order in which the various parts should be erected is therefore as follows:-
Base
Panel opposite the door
2 Panels adjacent to the door
Floor slab
Door frame
Transom panel
Roof
Door

44. Fixing of Door Frame
Owing to the elimination of the transom frame, it has been necessary to employ a mild-steel plate to accommodate the door-closing spring. The door, together with the fittings attached thereto (except the mild-steel plate referred to above), should be detached from the door frame. This latter item should next be fitted, and lightly screwed up.

45. Fitting of Transom Panel
The transom panel should be fitted in position, the steel weathering-strip being inserted between the bottom of the panel and the top of the door frame; this operation differs entirely from that specified for "Kiosk No. 3 (Mark 234)" in paragraph 25.

46. As stated in paragraph 41, the transom and its frame - used on the "Mark 234" kiosk - are combined in the "Mark 2" kiosk, and the instructions contained in paragraphs 28, 30 and 31 therefore do not apply to "Kiosk No. 3 (Mark 2)."

47. Application of grouting Material
A thin bedding of grouting material should be laid on the top of each of the four corners of the kiosk, to receive and fix the roof.

48. Fitting of Roof
Before fitting the roof, a piece of timber, on which the roof can be rested temporarily, should be placed across the top of the sides of the kiosk, to protect the edges of the roof and the sides from damage while the roof is being located. The timber may then be removed and the roof lowered into position.

49. Signs
"Glasses No. 43" should be used on "Kiosk No. 3 (Mark 2)."

50. Leading-in - General
The general principles of leading-in are detailed in paragraph 5, and the method of applying them to "Kiosk No. 3 (Mark 2)" is described in paragraphs. 51 and 52.

51. Leading-in - Overhead
A new bracket "Bracket No. 18" has been introduced for the purpose of leading-in from overhead lines to "Kiosks No. 3 (Mark 2)." The bracket should be fitted to the top of the side section adjacent to the rear section of the kiosk. The uppermost side-fixing screws should be removed, and the "Bracket No. 18" placed in position over the screw holes ; the bracket should then be secured in this position, using the two fixing screws supplied with the bracket for this purpose. "Cable, I.R.V., Braided and Compounded" from the pole or house. fixing should be passed through the clamp, through the ventilator on the kiosk, and terminated on a protector fitted to the wallboard. The slots in the floor slab and base should be filled in and cemented over.

52. Leading-in - Underground.
(a) Fixing of protecting conduit
Special conduit lugs are provided on the wooden battens fitted to the back section, for fixing lengths of 3-in. G.I. conduit when this is necessary (i.e. for protection of telephone and electricity-supply leads, when the kiosk is served from underground distribution).

(b) The telephone leads
Normally (i.e. when served from underground distribution), these leads should enter the kiosk via the slot arranged in the right-hand side of the back section, as viewed from inside the kiosk.

(c) The electricity-supply leads should be led into the kiosk by armoured cable or cable in conduit and should enter through the left-hand slot as viewed from inside the kiosk. Electric lighting should be provided in accordance with POWER, Lighting, A 3101.

53. Cabling of Root Light
On "Kiosks No. 3 (Mark 2)," special provision is made for cabling from the time-switch to the roof-light. This is a conduit assembly, which is cast into the concrete of the dome, consisting of a length of conduit fitted with a junction box at its upper end. Obviously, when the roof is being fitted, it is essential that the entrance to the conduit assembly, which protrudes about in. below the bottom edge of the roof, be immediately above the right-hand side of the rear section, i.e. the nearest point to the time-switch.

54. Items to be requisitioned separately
These are the same as required for "Kiosk No. 3 (Mark 234)" (see paragraph. 40), except that "Conduit Saddles, No. 2A" are not required, and "Glasses No. 43" are required instead of "Glasses No. 25."
