THE right approach to the problem of keeping all an industry's main products consistently before prospective users has been achieved over the years by the demonstrations of specialized vehicles and. equipment that are staged at the annual Institute of Public Cleansing Conferences. Exhibits are there to be seen, inspected and explained, but, although this is the appropriate place to show new ideas, there is no pressure of any kind to introduce different models for the particular occasion.
In short, the parade and the earthmoving equipment demonstration that are to be seen at Hastings next week are practical affairs, with no more concession to outward show than is demanded by proper respect for a public occasion. All the forecasts suggest that this is going to be one of those years when there is no great influx of new Models, although experience shows that in the matter of cleansing vehicles it is wiser not to be too definite, for there are always occasions when surprises materialize at the opening hour. Much progress in details of design, however, continues to be made in this sphere.
One new feature this year is the introduction by Glover, Webb and Liversidge, Ltd., of a packer plate for their Dual Tip range, either as an optional extra when new or for fitting to existing vehicles. This addition consists of a specially reinforced barrier plate that pivots from a point near the top of the refuse body and is actuated by two hydraulic rams located above the roof. When not in use it lies close to the roof over the rear of the loading hopper. Its forward and downward swing is made when the body is tipped forward and the refuse in the hopper has fallen to the front, the return stroke being made after the body has been lowered. Packing is thus carried out in the most advantageous position with the body fully dosed, the system ensuring an increase in total capacity. At the rear of the body is an aluminium-alloy roller shutter which is spring balanced, and with this dust emission is kept to the minimum. The mechanism of the packer plate is strongly constructed, rapid in action and simple to use, the driver having to operate only one extra lever in the cab. The device will be seen fitted to a I2-cu.-yd. Dual Tip Junior.
The same company will demonstrate the Dual Tip Senior which has a 25 Cu. yd. capacity and is capable of carrying over five tons of refuse. Enclosed refuse collection is
B24
featured in the Haller system collector with a Zoller dustless shutter. They will also exhibit a Blenheim compression refuse collector of 22-30 cu. yd. capacity which is mounted on a Karrier heavy-duty chassis with crew cab.
The range of Manulectric vehicles to be shown by the Stanley Engineering Co., Ltd., includes a new model which is fitted with a light alloy 3 cu. yd. body equipped with hydraulic tipping gear and an attractively styled glass-fibre cab. The model is, of course, electrically operated and it has a speed of up to 22 m.p.h. and a maximum range of 50 miles per charge.
Three David Brown tractor outfits are to be seen, probably the most interesting being a 950 Industrial wheeled type, with 42.5 b.h.p. oil engine and six-speed gearbox. This unit is equipped with a Danlirte front-mounted rotary brush for road sweeping and for snow clearance. The brushes are of Danish design and have carbon steel bristles mounted in sections on a welded tubular core. Front-mounted, the Danline is chain-driven from the tractor's p.t.-o. The brush can be raised and lowered by a cable actuated through the tractor's hydraulic system. A second David Brown outfit of relatively recent introduction is the 950 tractor, equipped with hydraulic front loader and Shawnee back-acter. There will also be a 40 TD crawler tractor with hydraulic angle-dozer.
A new salvage trailer, available with aluminium, steel or wood body, is scheduled for display by W. R. Pasbley, Ltd. It is the first trailer to be specifically produced by this company for municipal employment although, of course, their street orderlies have been exported all over the world for many years.
Development of design with the object of increasing load capacity has culminated in the introduction by the Eagle Engineering Co., Ltd., of the all-British CrushloaD collection body which incorporates an automatic, continuous loading mechanism but, additionally, the refuse is precompressed against a solid plate before entering the main loading cycle. Both mechanisms are actuated hydraulically from a continuously running pump which can still operate when the vehicle is stationary or moving slowly at the kerb. Features of this body include salvage lockers, a salvage rack and an underfloor tipping gear carried on a steel sub-frame. Other exhibits will include an Eagle 9-13
cu.-yd. Cornpressmore collection body for short-wheelbase chassis, an Eagle cesspit emptier and a combined gully and cesspit emptier.
The well-known Yorkshire R.S.C. road-sweeper-collector will figure among the models puron parade by the York
By ASHLEY TAYLOR, A.M.I.R.T.E., Assoc.Inst.T.
shire Patent Steam Wagon Co., but special interest will be reserved for this manufacturer's 1,000-gal. gully-cesspool emptier on a Karrier 9-ft. 7-in.-wheelbase chassis. This has a cab fitted with new equipment, details of which are being withheld until the day of the show. One of the lesserknown Yorkshire products to be seen will be a 450-gal. gully-cesspool emptier mounted on a two-wheel trailer and designed for driving from the take-off of an agricultural tractor or Land-Rover.
Washing equipment for crews is an idea to which increasing attention is now being given. This is optional equipment on the Dennis 1,400-gal. cesspool emptier, hot water being made available through a supply system
independent of the vehicle radiator. This manufacturer's Paxit range is to be represented by the Paxit III, the Major III and the Paxit II, with the addition of the 20-cu.-yd. Tippax. A high degree of component interchangeability is an attractive point with these Dennis machines.
Washing facilities are also provided on the Pendulum compression collection vehicle to be demonstrated by John Gibson and Son, Ltd. The supply system provides for a 5-gal. hot water tank being built into the chassis frame, with heating direct from the engine manifold. Provision is made within the body for the use of a hand basin by the men. The 18-27-cu.-yd. body is mounted on a longwheelbase Thames Trader chassis, the standard cab modified to accommodate a full crew. Other Gibson models that will be seen at Hastings range from 8-12-cu.-yd. to 22-35-cu.-yd. capacity.
A newcomer to the British market is the Swedish-made B25 Norba refuse collector, of which two specimens will be on show. One will be fitted with a bin lift adaptable for either circular or square bins. In the Norba design the refuse which falls into the hopper is compressed by screw action, and it is claimed that as much as 72 cu. yd. of light bulky material can thus be carried in the 16-cu.-yd. container. The drive for the screw is taken from the p.t.-o. on the gearbox. Discharge is carried out with the assistance of a hydraulic tipping mechanism that tilts the container backwards, so automatically opening the rear shutter.
In the new-design shutter fitted to the 18-cu.-yd. Shefflex dustless, self-loading and compacting refuse collector the mouth of the bin makes sealed contact with the shutter face during the whole of the operation cycle. Both ordinary or special hinged-lid bins can be arranged to give enclosed operation. Two bin hoists are fitted to the rear apertures and these can be worked either independently or both at the same time in order to increase the speed of the operation. Whilst the loading height can be fixed at anything from 12 in. above ground level, the refuse is discharged near the top of the body, so aiding consolidation.
A special attraction among the offerings of Lacre, Ltd., will be the recently introduced Model G which is a lowerpriced version of that manufacturer's suction road sweeper. This new machine is mounted on a left-hand-drive Bedford chassis and is provided with the same exhauster, sweepings 826 container and water tank as the standard model. However, only a vertical scarifying brush and suction nozzle are fitted and the maximum sweeping width is 3 ft. For removing heaps of leaves, litter and debris a 20-ft. wandering hose is fitted at the rear of the container. The alternative Model GG is designed specially for dealing with one-way streets and dual carriageways, having sweeping equipment on both sides.
Lewin Road Sweepers, Ltd., are to display two standard models, their Mechanical Orderly sprinkler-sweeper-collector and the Lewin Sweepmaster on a Seddon chassis. Both employ Perkins engines. Three, four, and six-cylinder oil engines are to be demonstrated during the exhibition by Perkins Engines, Ltd.
The Dempster range of specialist vehicles produced by the Powell Duffryn Engineering Co., Ltd., is now well established in cleansing circles and four machines will be seen at Hastings. Among them will be the Dinosaur which is one of the models that makes a strong appeal for bulk refuse disposal use. Although not ready in time for the conference, a new version of the Dumpmaster Bulk Refuse Hauler, similar to the 30 DO now in service on a numbei of disposal schemes, will be introduced this summer.

IE BENEFITS OF DODGE
'op Transport Man knows that Dodge scores heavily on all nts. Here's how Dodge, measures up : Dodge are famous for rugged reliability. Mud, snow, ice, ty loads, steep haul — it makes no difference. Dodge always ver the goods. Economically too. Dodge keep operating s at rock bottom.
Dodge are tough as teak. And because they are, they work ler and longer, even with extra heavy use. Longer working means higher returns on capital.
Dodge provide vehicles to meet the most varied speciticas. There are 54 basic models in the present Dodge family, ring from 3 to 12 ton load carriers and tractors for articulated .nd 12ton loads.
Dodge have a nationwide Dealer Organisation which gives -class after-sales service and easy availability of spares. Dodge are a 100% British product in design, labour and ern.
;ld is well known and at the conference they will be presented by four vehicles. In one case there will be a lenheim collection bodywork on a Bantam chassis; a arrier five-tonner will be mounted with a Yorkshire gully Id cesspool ertiptier, and two Gamecock chassis will carry ual Tip refuse equipment
Once again pride of place among the Shelvoke and rewry, Ltd., exhibits will be given to the Pakamatics. ew on this occasion will be a 35 cu. yd. model with ew cab and Perkins 6.354 engine. This is a somewhat taller version of the models which were seen for the first ne last-year. Two representatives of the 50-cu.-yd. type 11 be seen at Hastings, both with Leyland oil engines and e of them with container hoist gear. The S.D. range 11 also cover a pair of fore-and-aft tippers and a gully
The Ford Motor Co., Ltd., will feature Eagle bodywork various forms and will also show the Gibson Pendulum .shing equipment.
Special purpose units in the form of a grit spreader on a Lames 4D chassis, and a trailer gritter, are to be demonated by Atkinsons Agricultural Appliances, Ltd. Also this category will be the display of William Bunce and n which, in addition to a new snowplough, will include ractor-mounted sweeper-collector. Snowclear,'Ltd., will wide ploughs that not only fulfil their primary purpose but give year-round service for market clearance, edgetrimming and light angle-dozing.
Suction cleaning in its various guises continues to make progress. Johnston Brothers (Engineering), Ltd., are to show a unit of this type mounted on an Austin chassis and, for footpath use. Columbus-Dixon, Ltd., will offer the Littervac which is a pedestrian-controlled model.
In addition to showing the K.E.F. power sweeper, Kent Engineering and Foundry, Ltd., are to put several designs of Munivac suction cleaners through their paces. Specially intended for use on promenades, car parks and similar sites, the suction operated Litta-Snatcha forms the contribution of Sweeping Machinery and Equipment, Ltd_ The well-known pedestrian-controlled electric trucks of the Harborough Construction Co., Ltd., are also to be seen and a 4-cu.-yd. salvage trailer will come from W. Smith and Sons. A refuse trailer is to be shown by Whitlock Bros., Ltd.
Missing from the conference parade for the first time for nearly 40 years will be Walkers and County Cars, Ltd., who, nevertheless, hope to return to this field next year with a product of exceptional interest.
The demonstration will take place next Wednesday at the Oval, Hastings, commencing at 9.45 a.m. Earth-moving equipment will he shown the following afternoon at the Pebsham site.
