Description
  1. The Blaw Knox mobile Junior concrete weighbatcher is a small weighbatching equipment suitable for use in the field with batch type concrete mixers of either high-mounted or, standard type and of up to 21/14 cu. ft. capacity. It comprises: -

    1. AN ELEVATED MAIN HOPPER, of 20 cu. yd. total capacity, divided into three compartments for coarse and fine aggregates respectively. From the compartments the materials are discharged by gravity into a

    2. WEIGH HOPPER, where the required weights are shown on a scale dial. After being weighed, the unmixed materials are discharged by chute into the concrete mixer skip.  The main and weigh hoppers are mounted on

    3. PNEUMATIC-TYRED RUNNING GEAR, which permits the machine to be towed at convoy speeds by a suitable MT vehicle.

  2. The main hopper is fitted with flare-plates to facilitate filling and prevent spillage.  The flare-plates can be removed, and the main hopper lowered, to reduce the overall width and height when towing.  A suitable crane or other lifting tackle must be available when the equipment is to be erected, the weight of the flare-plates being approximately 27 cwt and that of the complete main hopper and flare-plate assembly 70 cwt.

  3. The weigh hopper is suspended by a series of weigh beams supported on knife-edge pivots and the weight-indicating mechanism incorporates an 18 in. dial of 2,240 lb. capacity with 5 lb. sub-divisions.  Three adjustable pointers can be positioned to show correct weights for the aggregates by accumulative weighing.

  4. Discharge of material from the main hopper to the weigh hopper is controlled by three guillotine type cut-off doors operated by separate handles at the side of the machine.  Discharge from the weigh hopper is controlled by a handle-operated gate type door.  The dial indicator can be assembled on either the left-hand or right-hand side of the machine to suit site conditions;  all operating handles should be assembled on the opposite side of the machine to the indicator dial.

  5. Brakes of the overrun type, and a detachable draw-bar, are fitted.  When the machine is in use, the chassis must be supported on timber packing spanning the full width of the frame and so arranged that the machine is level and the tyres are relieved of weight.  An adjustable leg is fitted to provide additional support for the weigh hopper and discharge chute and timber packing must also be provided as necessary beneath this leg.

This item of equipment appears to have been added to the 2nd Edition by the issue of AL57.

Road Machines 20 cu yd concrete weigh batcher (mobile) Mk 1

Road Machines 20 cu yd concrete weigh batcher (mobile) Mk 1

Description
  1. The machine is intended for the accurate batching by weight of aggregate, sand, etc., prior to the loading of the material into concrete-making plant. The main hopper is divided into three separate compartments for the reception of different materials; discharge of material into the weighbucket from each compartment is controlled by gate-type doors located at the base of the hopper.

  2. The weight of material discharged into the weighbucket is shown on an indicator dial calibrated in 5 lb. divisions to a total of 1,400 lb.  After weighing, the unmixed materials are discharged from the bottom of the weighbucket into the loader skip of an adjacent concrete mixer.  The support frame of the weighbucket is pivoted and so arranged that the bucket may be swung horizontally from under the discharge doors of the hopper through a complete circle of approximately 3 ft. radius. This arrangement enables the weigh batcher to feed the skips of two mixers, one at the side and one at the rear, without further handling of material.

  3. The weigh batcher, when in operation with its hoppers full, will be of an approximate weight of 22 to 23 tons according to the materials being employed: because of this, it is essential that the plant be positioned on a hard standing, or on a working base of timber or some other suitable material, before operation.

  4. The Plant cannot be operated until it has been supported on packing and the chassis removed or alternatively, with the chassis disconnected and moved forward in relation to the superstructure.  It is advisable to remove the chassis completely so that it can be stored away from the dirty conditions that exist in the vicinity of concrete mixing equipment.

  5. The flareplates, and their internal dividing plates, forming an extension to the main hopper, are readily removable; they must be removed before any attempt is made to tow the plant.

  6. The trailer chassis on which the superstructure is mounted is fitted with Girling brakes operated by a Clayton Dewandre air pressure system and must only be towed by a vehicle fitted with a two line air pressure system.  Disconnection of the trailer air lines from the towing vehicle automatically applies the trailer brakes and no hand parking brake is fitted.  Release of the brakes, when disconnected from the towing vehicle, can only be effected by releasing the air pressure from the trailer air reservoir thus rendering the brakes ineffective until the weigh batcher is again connected to a towing vehicle.

  7. The Mark 1 model of the plant described here is generally similar to the Mark 2 model described below, but there are two important differences which must be noted. These are: -

    1. Wheel removal -  The wheels of the Mark I model cannot be removed from their hubs until the superstructure has been removed from the chassis.  The wheels of the Mark 2 model are easily removable

    2. Flareplates - Each flareplate of the Mark 1 model consists of two separate sections bolted together.  On the Mark 2 model each flareplate is a complete sub-assembly.

MT required for transportation -

  • 10 Ton tipper or any similar vehicle fitted with two line air pressure brakes.

Millars' Concrete Mixer Type 10/7 (Trailer Mounted)

Millars' Concrete Mixer Type 10/7 (Trailer Mounted)

Description
  1. The 10/7 mixer, illustrated above, is of the non-tilting rotary closed drum type.  The mixer consists of a power-operated loader bucket, discharge chute, water tank and steel mixing drum rotating on steel rollers.  The power unit is a Bamford 5 hp petrol engine. The complete unit is fixed on a steel frame mounted on two pneumatic-tyred and semi-elliptic sprung road wheels; a towing bar and overrun brakes are also fitted.

This vehicle was shown in AP3036 (1st Edition) so was probably in use before 1944.  When AP3036 (2nd Edition) was issued, it was still included.

MT required for transportation -

  • Hands or Templewood trailer (for transportation)

  • AEC, Matador, 4x4, Tractor (for Towing)

Operation

The output of mixed concrete per operation is 7 cu. ft.  The number of operations per hour varies according to the individual conditions, from 10 to 15, thus giving an output per 8 hour day of from 21 to 31 cu yd of concrete.

Great care must be taken to level up the machine both ways before commencing work, and all weight must be taken off the pneumatic tyres by means of the jacks fitted. Failure to do this may result in a strained frame, undue wear of the mixing drum rollers, and damage to the pneumatic tyres.

The mixer should be set up if possible so that the prevailing wind does not blow dust and cement into the engine.

The length of time required for mixing depends on the materials and the amount of water in the mix.

Particular care must be taken when shutting down for meal times and at the close of the day's work to ensure that the mixing drum is left free from concrete, by washing out with gravel (or stone) and water.

The mixer may be towed for considerable distances, but at speeds not exceeding 20 mph and whenever moved should be inspected on arrival at the new site to ensure all bolts and nuts are tight and that no damage has resulted due to transportation.

Data

Millars' Concrete mixer, Type 10NT

Millars' Concrete mixer, Type 10NT

Description
  1. The Millars' mixer, Type 10 NT is of the non-tilting drum type, and embodies a power-operated loader, a self-measuring water supply system and a manually controlled discharge chute which can be used to cut off the discharge when the barrow or skip is fully loaded.  The unit is mounted on a four-wheeled pneumatic-tyred trailer with a tubular draw-bar terminating in a standard towing eye.

  2. The unit is entirely self-sufficient in operation, apart from the necessity of connecting a water supply to the metering cistern.  Stabilizers are fitted to the wheels on the loading side to prevent flexing of the tyres due to the side load of the filled loader bucket.  All control levers are grouped at the rear end of the plant, enabling one operator to raise and lower the loader, add the correct amount of water to the 'mix" and control the discharge chute.  The amount of water admitted to each "mix" is controlled by a pre-set hand wheel on the water tank, the scale being calibrated in gallons and pounds.

  3. The 10 NT mixer is powered by a Ruston Hornsby diesel engine developing 7 hp at 1,000 rpm, driving through a centrifugal clutch and roller chains to the drum gear and loader countershaft.

Holman Concrete Compactor Model CC2/Holman Screed Board Vibrators, Models CC2 & CC3

Holman Concrete Compactor Model CC2

Description
  1. The Holman screed board vibrators, Models CC.2 and CC.3, are air-operated plate-type vibrators for the compaction of flat, horizontal or near-horizontal concrete surfaces such as occur on roads, runways or floors etc.

  2. Each machine consists basically of a long U-shaped steel channel, forming a screed board, attached to a steel batten by spring-loaded retaining pins.

  3. On Model CC.2, two piston and anvil bar assemblies, on Model CC.3, three piston and anvil bar assemblies, each consisting of a vertical cylinder in which an air-operated piston is allowed to reciprocate, are bolted to the top face of the batten so that each piston at the end of its down stroke strikes the head of an anvil bar mounted in a guide in the batten and resting on an anvil plate welded to the channel.  The impact of the piston on the anvil bar is transmitted through the anvil plate to the channel and provides a tamping effect on any material on which the channel is resting.

  4. The pistons reciprocate continuously all the time that the control valve of the tool is open, provided that the weight of the vibrator is taken by its working face.  If the channel is allowed to hang from the batten, as when the vibrator is lifted from the job, the air supply to the piston and anvil bar assemblies is cut off by the action of a contact valve mounted in the batten.  A screw-type control valve is provided for normal on/off control.  Air is supplied to the vibrator through an air adapter at the end of one of the handles.

  5. Two operators are required for the vibrator; the operators hold the handles at each end of the tool and guide and steady it over the surface of the wet concrete.  Under favourable conditions, with a low water-cement ratio, the compacting effect will extend to a depth of 8 or 9 in. below the surface of the concrete and the compacted concrete can be stood on immediately without making any indentation.

  6. These vibrators leave a ribbed surface which assists in the prevention of skidding or for the "keying" of a subsequent coat of asphalt or tarmacadam. No attempt should be made to obtain a smooth surface with these particular vibrators; if a smooth surface finish is desired, a finishing screed must be used after compaction has been effected.

The CC2 appears to have been added to the 2nd Edition by the issue of AL88 but this was joined by the CC3 in AL94, to which this entry has been amended.
