Abstract
An apparatus for collecting particulate material has a collection tray (1) and a fire-resistant collection reservoir (21, 22, 23). A scraper blade (24) is attached to a carriage (7) which is arranged to be driven by an electrical motor along the base of the tray (1) so as to sweep particulate material into the reservoir (21, 22, 23). A pivotal lid normally closes an opening into the reservoir (21, 22, 23) until the scraper blade is ready to sweep particulate material into the reservoir, whereupon the lid is opened to receive the swept particulate material. Actuation of the lid for the reservoir may be operated by electro-mechanical switches or by a solenoid (60).
