The 25-cwt. Stores Carrying Vehicle (Enclosed) Type 1 (Seddon Diesel)

1. General
This Instruction describes the 25-cwt. Stores Carrying Vehicle (Enclosed) Type 1 (Seddon Diesel). This vehicle is most suitable for use in stores carrying pools where the stores to be conveyed, e.g. telephone apparatus, need the protection of an enclosed body, but the capacity of the vehicle and the facilities provided will not confine it to the conveyance of apparatus only.

Note:- The vehicle is intended for stores carrying only and should not be demanded for use by small gangs or working parties.

2. Description
The main body work is constructed of timber, clad with fibre glass. A centre panel in the roof has been left unpainted to give improved natural lighting in the body, and should be kept clean. A general view of the vehicle is given above.

3. Cab
A view of the cab is given in Fig 2. The seating arrangements in the cab provide a seat for the driver which is adjustable forward or backwards and an occasional seat and backrest for two passengers. The passengers' seat is of the folding type which enables it to be secured in the folded position to give clear access from the cab to the body of the vehicle when this is required.

4. The cab is divided from the body by a fixed partition with a sliding door. The fixed portion of the partition has a window to provide a rearward view through the body of the vehicle, and the cab side of the sliding door carries two metal containers for the log-book and papers.

5. A writing flap which slides out from under the dash panel is provided on the near-side of the dash panel within easy access of the driver's seat. The flap may be illuminated by a lamp situated on the face of the dash panel.

6. The vehicle toolbox is housed beneath the cab floor under the passengers' seat. The box is provided with hasp and staple for securing with a padlock. Access to the box is obtained by lifting the passengers' seat and raising the cab floor covering. The box will contain all the vehicle tools except the jack handles and the starting handle which are mounted on clips on the partition behind the driver's seat and on the underside of the passengers' seat respectively.

7. Access to the vehicle battery is obtained by sliding the driver's seat forward and removing the wooden floor trap thus exposed. The battery master switch is placed on the cab floor alongside the driver's seat and is shielded against damage.

8. For normal driving conditions the cab sliding doors should be shut, but in foggy weather or when manoeuvring in a congested space it may be found to advantage to have the doors open, and they should then be secured in the open position by the catches provided.

9. Body
The body consists of a plain box body measuring approximately 8 ft. 9 in. long, 5 ft. 5 in. wide, 4 ft. 11 in. high. Wooden slats are fitted to afford protection to the body sides and two wheel arches are arranged to form two shelves complete with fence rails.

10. Racking has not been incorporated in the design as a standard feature, as in most cases the range of stores that may be caned render the need for specialized racking unnecessary. Should it be found that, in some conditions of use, some racking is essential, consideration will be given to the fitting locally (in conjunction with the R.M.T.O.) of a simple form of racking, possibly constructed from slotted angle; the Eng. Dept. (Cn) should be advised of the requirement. The use of Minor Van Fittings, Units A, B and C may well provide the facility required.

11. Items of stores that are likely to fall over or roll during transit should be secured by lashing to the wooden slats at the sides of the body.

12. To facilitate the carrying of conduit up to approximately 13 ft. 6 in. in length which on occasion may be necessary, the passengers' seat has been arranged to provide a clear space under the seat to enable the conduit to be pushed through into the cab, thus enabling advantage to be taken of the maximum length of floor space available within the vehicle. The carrying of longer lengths than can be contained within the vehicle with the rear doors closed should not be attempted with this vehicle.

13. An electric lamp controlled by a switch situated in the cab provides illumination within the body of the vehicle.

14. Two coat hooks are provided on the fixed portion of the partition on the off-side of the window.

15. The two hinged doors at the rear of the vehicle when opened may be secured in the open position at 900 or 2700 by door stays and catches respectively as shown in Fig. 3. The doors when left open must always be secured in position.

16. A step situated immediately below the towing bar facilitates easy access to the body of the vehicle from the rear. The step is arranged to slide in channels and is secured in position either stowed or out for use by two spring-loaded bolts. The step must always be bolted in either the IN or OUT position. The step must always be in the stowed position when travelling.

17. Maximum load
The maximum load which may be carried on the vehicle excluding the driver and one passenger is 25 cwt. The gross moving weight of the vehicle should not exceed 3 tons 5 cwt.

18. Towing facilities
A pin-type towing clevis is provided. The weight which may be towed by this vehicle must not exceed 12 cwt. This in effect restricts the use of the vehicle to the towing of trailer tool carts only. When operating over terrain where gradients steeper than 1 in 7 are encountered towing should not be attempted with this vehicle when a load greater than 15 cwt. is being carried in the vehicle. A three-pin socket situated on the rear lower off-side of the body provides for connexion of the trailer rear lights. To facilitate connexion to the small bayonet catch plugs on trailer tool-carts an adapter is provided and carried in the tool-box. The adapter consists of a short length of flexible lead with a three-pin plug at one end and a S.B.C. socket at the other end.

19. Locking arrangements
Standard FA600 series barrel-type locks are fitted to the cab, partition and rear doors. In addition the partition and rear doors are fitted with a hasp and staple for use with padlocks.

20. Spare wheel
The spare wheel is housed beneath the body of the vehicle in a carrier which is provided with a spring clip to secure the locking bar clear of the opening when removing and replacing the spare wheel.

21. Damage to paintwork
Touching up of the paintwork should not be attempted by the users of the vehicle, as such work will be done by the Mechanic I/C with the correct materials when repairs or overhauls are carried out.

22. Overall dimensions
As a guide for garaging space the overall dimensions of the vehicle are:-
Length, 17 ft. 0 in.
Width, 6ft. 5 in.
Height, 7 ft. 9 in.
