MODERN CLEANSING METHODS GAIN GROUND

VISITORS to the vehicle parade at the Institute of Public Cleansing Conference at Southport will have the opportunity of inspecting a number of important developments. However, most manufacturers are pinning their hopes to models introduced during the past two years or so for which repeat orders are now coming through. Modernization of many fleets is in progress, usually based on designs that have already been able to prove their worth.

The I.P.C. vehicle parade is to take place at the Pleasureland coach park on Wednesday, June 19. Demonstrations of earthmoving equipment will be seen on the Thursday afternoon at the Cheshire Lines site which is adjacent to the Pleasureland park.

Staff amenities on tipping sites are all too often of a primitive nature but at Southport, Glover, Webb and Liversidge Ltd. will be showing the Marlborough mobile tip unit which can be used for conveying men to and from their places of work and to provide hygienic cooking, messing and toilet facilities on the spot.' Mounted on a B.M.C. 2-ton forward-control chassis, the body is fitted with a Calor gas hotplate, stainless steel sink and has comfortable seating for four men at a Formica top table.

The Ramillies 50-cu.-yd. continuous-loading refuse collector, introduced at the Public Works Exhibition last year, will be displayed in two forms, both on Karrier chassis and with crew cab. Bodywork is in aluminium alloy and in operation only one moving part comes into contact with the refuse. The second version of the Ramillies will be equipped with a giant bin-lift attachment that can quickly be stowed away near the roof so as to enable the vehicle to carry on dealing with normal containers. Glover will also show two specimens of the Dual-Tip and a Haller collector with Zoller dustless loading shutter.

A power loading device for emptying ordinary open-top dustbins quickly and hygienically, without the need for special hinged lids, is to be demonstrated by Dennis Bros. Ltd. Co-operation on the technical side between this company and Johnston Bros. (Engineering) Ltd. has resulted in the production of the Dennis-Johnston Mk. II suction sweeper which has been designed from the outset as a complete unit. It incorporates the Dennis constant-mesh five-speed gearbox which provides for full engine torque being taken from the top p.t.-o. The refuse-collection vehicles being shown are based on the Dennis Pax V chassis with Perkins 6.354 engine and cabs with accommodation for crews of seven in addition to the driver. Light metal bodies of the Paxit III and IIIA range are all suitable for dustless loading of the 24and 3i-cu.-ft. bins, for bulk container hoist gear, and for ordinary hand loading.

Johnston suction sweepers themselves are available in two designs. the Standard and the Dual Sweep, the latter being arranged for nearside and offside operation. Both are obtainable on Austin 5-7-ton chassis with a choice of the B.M.C. 5-1 litre oil engine or the 5-7 litre with five-speed gearbox.

Since the first M.P.L. system went into operation at Hammersmith last January great interest has been shown in this development. On a small stand in the appliances section Fawcett, Preston and Co. Ltd. will be displaying photographs of the M.P.L. in operation, whilst Walkers and County Cars Ltd. will have one of the special vehicles available for inspection. The heart of the system is a 67-ft.-long static press, built by the Fawcett, Preston organization, which produces a refuse cartridge 20 ft. long, 7 ft. dia., and weighing up to 14 tons.

The smallest version of the Eagle Compressmore range, with a capacity of 9/13 Cuyd., is to be shown on a B.M.C. short-wheelbase

chassis that should !I-lake for a high measure of handling ease when collecting in back lanes and restricted areas. The floor slopes at the rear to give a reduced loading line and in this section abrasion-resistant replaceable steel sheets are used for the floor covering. A double-acting hydraulic rain is arranged to provide the maximum effort forwards and, by means of a trip mechanism, to give a rapid return to the loading position. The Eagle Engineering Co. Ltd. will also be demonstrating a crush-loading model on a Bedford 151-in. chassis with Eagle seven-seater coachbuilt cab. Here, doubleacting pressure plates are designed to give increased compression of the refuse.

Several municipal vehicles based on the Bedford TK chassis will be offered for inspection by Vauxhall Motors Ltd. On a Compressmore 12/20-cu.-yd. body a bin-lifting gear, capable of handling trunnion-fitted containers up to Cu. yd., is offered as an option. Other Bedford-Eagle units are a 16/24-cu.-yd.

collector and an 800-gal. gully and cesspit emptier. The Vauxhall range at Southport will also include the BedfordGibson Pendulum 12/l8-cu.-yd. collector and the Bedford-Lacre road sweeper-collector.

Following the introduction of the big Pakamatic design two years ago, Shelvoke and Drewry Ltd. last year presented a 35-cu.-yd. model and this time visitors may expect to see a 20-cu.-yd. variety with Perkins 4.236 engine, four-speed gearbox, and four-seater cab. The width of this model is only 6 ft. 6 in. There will also be three representatives of the large Leyland-engined Pakamatic and one of the middle size with its Perkins 6.354 power unit. A Fore-and-Aft tipper fitted with compressing mechanism is to be displayed.

Ranging from 12/18 cu. yd. to 20/30 Cu. yd., the well-known Pendulum bodies produced by John G:bson and Son Ltd. will be shown on chassis of B.M.C., Karrier, Ford and Bedford manufacture. In several cases they, will incorporate the Gibson bin discharge equipment andsome will have Gibson's coachbuilt crew cabs. In addition to the Ford chassis shown by manufacturers of cleansing appliances the Ford .Motor Co. Ltd.will have its own exhibit which will include a Thames 160-in.-wheelbase chassis carrying an 18/26-cu.-yd. Eagle Compressmore. body. The Austin Motor Co. Ltd. will show both Pendulum and Cornpressmore bodies on its chassis.

The Karrier contribution will include a Bantam 8-ft. 2-in.wheelbase, chassis caroing an 11-cu.-yd. Blenheim compressing body for use in confined areas. A Dual Tip Junior will also be shown on the Bantam chassis._ Destined for Oldham is a Gamecock with l8-cu.-yd. Dual Tip body, -a trailer towing attachment and upturned exhaust fitted in accordance with customers' requirements. The Ramillies 35-cu.-yd. will be seen on a Karrier II-ft. 9-in, chassis and the top capacity Ramillies on a 13-ft. 6-in, chassis withltootes oil engine. A Yorkshire combined gully and cesspool emptier will also be shown.

The range of Dempster Dumpster collection units to be seen will include the CA30-24 DB which has a rated capacity of 60 cu. yd. and will be mounted on a Foden FG 6/20 chassis. There will also he a Model DR 38, on a Leyland chassis, this having an open top, ram-plate packing and discharge. Two hoisting units will be exhibited, one on an Austin and the other on a Bedford chassis. A Dodge, fitted with York third axle, is the basis for a Dempster-Dinosaur transfer loader and transporter which is capable of lifting or setting down its own body on the ground or elsewhere; containers are available from 8 to 30 cu. yd. capacity.

Two types of Norba collectors are to be featured by Bech, Neale and Co. Ltd., and trailers suitable for refuse and salvage will be offered by Wm. Smith and Sons Ltd.

Light electric vehicles with a variety of applications are produced by the Stanley Engineering Co. Ltd. The Manulectric pedestrian-controlled street orderly truck has found favour with many undertakings in the cleansing field and a specimen will be on show at Southport. This will be accompanied by the driver-operated Manulectric Model-7 which has a 34-cu.-yd. fight-alloy body and twin-ram hydraulic tipping gear. The Model-7 has a range of 50 miles on a single charge. Four versions of the Harbilt vehicles will be shown by the Harborough Construction Co. Ltd. For the first time in many years Shefflex Ltd. will not be seen at the I.P.C. demonstration. The Shefflex machines are at the present time being redesigned to provide further increased capacity and higher compression ratios that will be suitable for the progressively lighter and bulkier refuse now being produced.

A newcomer to the floor-sweeping field is the Corvette 50, which is the first machine to be built in a diversification programme undertaken by Motor Rail Ltd., hitherto specialists in dumpers and similar equipment. The Corvette is an Anglicized version of an established model made by Balayeuse Mathieu, of France, from whom Motor Rail has obtained the U.K. manufacturing rights. This unit is claimed to be suitable for all areas from factory spaces to docks and is operated by two levers, a clutch control on the steering handle, and a throttle. The brushes, which are vacuum assisted, have a floating action and the unit is stated to clean an area of 1,220 sq. ft. in five minutes. A 3 h.p. petrol engine is employed. Dust is drawn into a filter bag and refuse into a 11-cu.ft. container.

In the hands of R. S. Stokvis and Sons Ltd. will be seen two models of the Tennant power sweeper. The Model 40 runs off a single-cylinder 4 h.p. petrol engine and has a clearance width of 34 in. As a result of the brush and vacuum fan action, dust is thrown up into a bag whilst the litter falls into a lower container.

A new design of the Verro City suction sweeper is to be shown. This model, which was designed from its inception as a road sweeper and is not on a converted commercial chassis, has already been fully tested in Scandinavia. The driver sits centrally and the outfit has been planned to permit sweeping dose to parked vehicles. Two scarifying brushes are provided instead of the former single brush that could be hydraulically transferred from one side to the other. The spring action that thrusts the brushes outwards allows wander of the sweeper away from the kerb without loss of contact.

Ar.other suction cleaner, the Litta-Snatcha, will be the principal exhibit of Sweeping Machinery and Equipment Ltd. It is an appliance of compact design which can be operated from the pavement, picking up much litter from the gutter even when cars are parked at the kerb. For this purpose the LittaSnatcha employs a wandering hose. A further piece of equipment is the metal discharge chute which enables debris to be emptied over the side into a collection vehicle or into other receptacles.

Fresh to the mechanical cleansing sphere is the Glutton sweeper-collector, which will be presented by H. Young (Motors) Ltd. This appliance is designed for towing behind a tractor and incorporates a 1-cu.-yd. refuse container, also an 80-gal. water tank. Hydraulic tipping is carried out by means of connection to the tractor system, Robustly made, the Glutton is intended to take in its stride site work, parks, goods yards and other areas where the clearance of cans, paper, rubble and other debris perhaps presents a problem.

Those well-known products of Lewin Road Sweepers Ltd., the Sweepmaster and the Mechanical Orderly, will again be making their appearance. The former is carried on a Seddon 758 chassis with Perkins oil engine and has been specially developed for county road conditions. In place of the beltdriven designs employed until recently on this model, gear-operated hydraulic and water pumps are now being used, whilst flashing direction indicators are being carried at the front and rear in the place of the side-mounted type. The Mechanical Orderly specification remains unchanged.

Suction road sweepers in two main forms will be demonstrated by Lacre Ltd. whilst there will also be the economically priced Lacre sweeper-collector. In all cases Bedford chassis are employed.

From the Yorkshire Patent Steam Wagon Co. will cote a heavy-duty road sweeper with Perkins P6 engine and a cab providing notably good driver visibility. There will also be the Yorkshire Litterlifter with the dustproofed 8-h.p, oil engine. The latter appliance will sweep a 4-ft. path, having suction

assistance to raise dust and paper. The Karrier-York shire 1,000-gal: gully and cesspool emptier is mounted on the Karrier WAFS.515 oil-engined chassis. Yorkshire's finger-tip control servo-Crane will be shown on this vehicle and, in addition to vertical movement of the suction pipe, the suction valve servo operation will be shown for the first turtle. A further feature of this model is a water jet at the bottom of the suction pipe to assist in the cleansing of gullies. Other varieties of cesspool emptiers will he shown, also a 450-gal. trailer gully emptier, towed by a Fordson Dexta tractor, this being intended for authorities having only intermittent use for such equipment.

An exhibit Of interest from Metering Pumps Ltd. will he the Atumat high pressure sewer cleaning tanker which comprises a 4-ton chassis carrying an 850-gal. water tank with an Atumat high pressure pump having an ouptut of 24 gallons per min. Normal working pressure is 900-1,000 psi., with a maximum of 1,200 p.s.i. The pump is driven through pulleys and belts from the vehicle p.t.-o. Two hose reels are located at the rear, one power-operated and the other for manual use. The first accommodates 300 ft. of h.p. hose and is fitted with a sewer cleaning nozzle; the second reel has 60 ft. connected to a high pressure spray gun for use in scouring manholes before cleansing commences. A control and instrument panel is fitted at the rear of the vehicle, Wayne power sweepers will be among the exhibits of Walker's Mechanical Cleansing Ltd.

In the snow clearance section Mercedes-Benz (Great Britain) Ltd. will exhibit an example of the versatile Unimog vehicle fitted with a snow blower driven from the p,t.-o. and a snowplough blade. The bodywork of the exhibition model has been adapted to take a gravity feeding hopper for road gritting. William Bunce and Son will be showing the UnimogSchmidt rotary snow cutter and during the earth-moving demonstrations the Unimog will be seen operating with a bulldozer blade and a rear-mounted Demag back hoe.

The Rolba Snow-Boy, the Rolba 2012 and Rolba-Landrover snow appliances have already been seen at I.P.C. demonstrations. but the new Rolba Snow-Bull will no doubt attract considerable attention. This machine, which runs on crawler tracks, is said to climb on to any snowdrift and to remove the snow in layers of up to 5 ft. depth per pass. Snow-removal capacity is given as up to 650 tons per hr. and clearing speeds range from 0-125 to 5.3 m.p.h. By means of dual-acting hydraulic cylinders the bk.wer head can be pressed down on to the a36 surface or can be tilted 15° to the left and right in order to follow the road camber. An air-cooled Deutz oil engine with an output of 80 b.h.p. at 2.200 r.p.m. forms the source of operating power, whilst the tractor engine is a water-cooled Hercules giving 30 b.h.p. at 1,700 r.p.m. The Snow-Bull exhibition machine has been reserved for the Northumberland County Council and next winter will be available for demonstration in that area.

Gritters of various types will be shown by Atkinson's of Clitheroe Ltd. and Gloster Tractors Ltd., whilst Snowclear

Ltd. will again be showing the Meyer snowploughs. An independently operated gritter body, mounted on a Ford 413 chassis, will be the principal exhibit of Atkinson's of Clitheroe Ltd. This unit is fitted with its own petrol or oil operating engine, _complete with centrifugal clutch, and a self-starter is now being provided as an optional extra. The gritting engine, when started, is controlled by a -throttle lever in the cab and the mechanism can therefore be put into operation at will by the driver. At idling speeds the gritting device is stationary.

The display caravan of the Perkins Group will be at the conference and. specimens from the Perkins oil engine range will be available for inspection.

Thursday's earth-moving demonstration will bring together an interesting selection of tractors and equipment, among them. being a Fordson Super Dexta with four-wheel drive conversion by' Roadless Traction Ltd.

The Fordson 3.6-litre Power Major is employed in the MuirHill RD2 rear-wheel-drive loader that is to be displayed by E. Boydell and Co. Ltd. A Fordson 3-6-litre Super Major is fitted 'to the Muir-Hill BD4 tractor shovel, the action of which is particularly suitable for face and stock-pile working.

A representative selection of machines from the International range will be presented by. R. .Cripps and Co. Ltd. among. them being the Cub Cadet tractor fitted with a Danco snow blower. This outfit is intended especially for speedy pavement clearance.
