A Dennis Innovation Which Ensures E.flicient Load Distribution
ANOTHER clever idea to aid the municipal cleansing officer in his duties stands to the credit of Dennis Brothers, Ltd., of Guildford. It consists of a device known as the Compactor, which was seen last week at the Agricultural Hall, London, installed on a 7-cubic-yd. refuse collector, the basis of which was one of the company's forward-control 2-ton chassis. This chassis was recently described in the pages of this journal.
For refuse-collection work, of course, the 26-in. by 3i-in. wheels are employed, in order to reduce the loading height to 4 ft. 6 ins. As the novel part at the outfit consists of the Compactor itself, we will confine our attention to its features.
Inside the body there are rails running from the front and to within 2 ft. or 3 ft. of the hinged rear door. At the forward end of th3 body there is a loading aperture .which may be closed by any of the well-known devices, the design, of course, being made to suit the bin system in operation in any particular district. The loading aperture may, if desired, be increased in size by the use of hinged flaps.
The refuse is dumped on to the rails, the smaller items falling through to the bottom of the vehicle, whilst the larger ones rest on the rails. When the loading space becomes congested the hydraulic pump of the tipping gear is brought into action to operate a plate, which moves backwards and forwards on guides. It has an automatic trip gear so that its direction is reversed at the end of each stroke. The rubbish is, therefore, forced backwards so that the load is compressed towards the rear.
For discharge purposes the rear
door may be opened, the Compactor plate operated and the load thus loosened prior to tipping. An ingenious point is that there is no need for disconnecting any pipe before tipping, because the connection between the hydraulic mechanism on the chassis and that above the body is through a hollow pivot pin.
A neat feature of this body is that there is only one aperture, so that• the effect of wind, even when the covers are drawn back, can be disregarded.
