Open the CIPO recordAbstract From the Canadian patent
An eavestroughing system is provided with brackets which permit sliding movement of the eavestrough relative to the roof of a house so that the eavestrough may be moved under the eaves of the house during winter. This inhibits the accummulation of ice on the roof and reduces the damage caused thereby.
