Devices to Facilitate Loading and to Prevent the Escape of Dust in Refuse Collection were Prominent at the Demonstration Held at Blackpool Last Week.
AT the conference of the Institute of Public Cleansing, which was held at Blackpool last week (June 3rd to aline 7th), the whole of Wednesday last was devoted to the parading of vehicles and appliances representing the latest types of equipment used in the publiccleansing services.
The 42 dust-collecting wagons, gullyemptiers, street-sweepers, etc., were assembled at the new Stanley Park, and after being ranged in a predetermined order were singly introduced to the delegates, and a demonstrator, accompanying each exhibit, was allowed five minutes in which to point out distinctive features. Arrangements were made for the gully-emptiers to be shown at work under normal conditions. Delegates also had the opportunity for requesting .private demonstrations, and these were given on the Wednesday afternoon and on. the Thursday, when, we understand, the machines were seen by representatives of the Government
Departmental Committee appointed to consider a report on the London publiccleansing services.
Self-closing Covers.
Most of the vehicles on view were dust-collecting wagons and they were fitted with all sorts of cover contrivances to render them so far as possible dust-proof. It is plain that the line of development with this type of low-load wagon is in the direction of still more efficient patterns of cover, but, as Mr. T. Robinson, of Newcastle-uponTyne, painted out in the paper that he read on Friday on "Modern Methods of house-refuse Collection." in all cases where the human element is privileged to exercise an option, that option invariably takes the line of least resistance and covers are more often found open than closed. He pointed out that the more recent develipmenf of fixing covers that are normalfy closed, and Can
only remain open for such time as the controlling device is held down, marks a considerable advance.
Electric vehicles were well represented by the G.V., the Electriear and the Garret. The first-named has an hydraulic tipping body of 6 cubic yards • capacity, the load being protected by spring-actuated roller-blind shutters made of canvas. Of the three Electrilcars, two were two-tonners and one was three-tonner. One had a treadlooperated sliding metal cover, anothev a canvas cover and the third the Ochsnee patent roof for use with a type of refuso bin the lid of which is kept open during the tipping operation by a fitting on the
• roof of the wagon. Electricars, it iS claimed. can be worked at an all-inclusive consumption of one unit of elec.
tricity per mile. The Garrett 5-ton vehicle, with a loading height of 4 fit. 6 ins., has a capacity of 141 cubic yards. The body is all-steel and is arranged for side tipping, but no tipping gear 31
carried, the necessary lifting gear having to be installed at the depot. This arrangement saves deadweight and has a bearing on repair and overhead charges. Spring-roller blinds in four sections are fitted to the top of the body. A Tudor battery of 500-amp.-hours capacity is located behind the driver's cab.
The only stripped chassis on view was an Easyloader, shown by B. Woodhead and Co., Ltd. This incorporates a 14-30 h.p. Mac engine and its load level is only 2 ft. from the ground. Much interest was taken in the Dennis 30-ewt. chassis, on which is mounted a body incorporating one particularly novel feature, namely, that the driver'S cab is part of the tipping body and is, therefore, lifted when the load is being tipped out. The frame height of the chassis is 20 ins, from the ground and the loading height is kept very low—a great advantage when working from pavements. Another member of the same family is the W..and G. low-loader, which was fully described in the issue of The Commercial .4: otor dated April 30th. The model shown at the Institute conference demonstration had a special dust-proof roof,' operated by an arm at the .side of the body. Thig caused the metal slide covering the load to shoot back, returning to the closed position when the hold was "relaxed. This ensured that the load was covered when travelling.
Another low-loader exhibited was the Dearne, designed by the Dearne Motor Co., Ltd., of Doneaster. Its capacity is 24.-3 tons, the load being contained in a steel hydraulically operated end-tipping body. Enclosure of the refuse is effected by canvas covers in six sections—three on each side—which are supported on hardwood hoops. The loading level is 4 ft. 4 ins, from the ground.
An impbsing, display of Freighters was made by Shelvoke and Drewry, Ltd., which concern exhibited five vehicles, the best known being the dustless loader of 10-cubic-yards capacity. The other four machines were :—A water tanker, interchangeable With 10-cubic-yards dustless loader ; a dust cart. of 10-cubic-yards capacity with canvas roof ; a refusecollector of 7-cubic-yards capacity with
metal roof ; and a dust cart of 7-eubieyards capacity with two sections on each side.
The Garner 24-ton low-loader has a cubic capacity of 7 cubic yards, the body being interchangeable with a 500-gallon water tank. In this case a canvas covering is fitted to enclose the load and hydraulic end-tipping is provided.
Puke and Bell,' Ltd, featured a i0-cwt. Morris multi-purpose vehicle. The body space is 120 cable ft. when the canvas covers are in use and 51 cubic ft. when they are removed. This vehicle can be easily adapted for general haulage work and is fitted with a gritting attachment for the treatment
of slippery roads. The standard body is also interchangeable with a tank for street-watering purposes. The other ■ Morris vehicle, exhibited on the day in question, was a 30-ewt. unit fitted with a four-sectioned sliding roof.
The Vulcan machines exhibited come prised a 30-35-cwt. low-load refuge tipper, a 30-cwt. general-purposes vehicle and a 3-ton low-load tipper. . The two dust wagons are of 5A-cubicyards and 7-cubic-yards capacity re-. spectively, the smaller vehicle having an underslung chassis And carrying a body with canvas top, the loading height being about 4 ft. 6 ins.
patent rotary refuse-carrying bodies were exhibited by the Eagle Engineer ing Co., Ltd., one of three-tuns capacity and • with two • sizes of . ports being mounted on an A.E.C.-type 427 chassis and the other, of two-tons (7-8-cubicyards) capacity, in attachment with an International tractor.For the purpose of disposing of bulky articles such as mattresses. and old bicycle frames there is a cupboard at the front of the container where these can be deposited.
One of the Karrier range was fully described in last week's issue. We noted the Karrier-Eowler gullyemptier, the 3-ton low-loader houserefuse collector, the 3-ton dustless refuse collector, a road sweeper and 'washer, and a road sweeper and dust collector.
The Dennis combined gully-emptier and street-washing and watering machine Was one of the Blackpool Corporation fleet. This is a machine that has been designed to cope with these twin duties in towns, the size of which would not warrant the purchase of a separate unit for each purpose. The outstanding feature is that the vehicle may be used in any one of its three capacities without a single part being changed. Some 60 gullies to 70 gullies can be dealt with before the vehicle discharges its load.
The Pagefield system of handling household refuse was demonstrated by one of three machines—a five-tonner of 8-cubic-yards capacity, a five-tonner of 8i-cubic-yards capacity, and a fourtonner having a capacity of 7 cubic yards.
In the steam class notice was merited by the Yorkshire and the Fowler gullyemptiers, the former combining the functions of gully-emptying with a capacity for street-washing. The container will hold 700 gallons of sludge and 800 gallons of water. The Fowler has a clean-water tank of 1,020 gallons capacity and a sludge tank for 900 gallons, whilst the separate upper vacuum tank holds 165 gallons in addition. The sprinkling heads are carried on both sides just behind the driver's cab. The pressure is ample to cover a width up to 50 ft. when required.
Of the two Thornycrofts, one was a 2-ton end-tipper mounted on an A2 type chassis, and the other a 5-6-ton three-way tipper, carried on a JJ-twe chassis.
Street sweepers were represented by Laffly and Lacre units, which are well known in municipal circles. Another Lucre machine was the 2-ton low-load dust-collecting wagon—a sturdy and business-like example of workmanship.
