Abstract

Gutters and downspouts on buildings such as home conventionally communicate with drain lines for the disposal of rain water. The drain lines are sometimes connected with sewers by way of a footer drain around the foundation of the building and sometimes communicate with dry wells adjacent the building. A problem with all such downspout drainage systems is that particulate material such as leaves, small pieces of roofing and other kinds of debris tend to enter the system through the downspouts. The material accumulates in the drainage lines including the footer drains around the foundation and often fills up the dry wells with the undesirable result of storm water being introduced into the basement of the building and the resultant damage to articles in the basement as well as the foundation walls and basement floors. These problems can be eliminated by preventing the debris from entering the footer drains and/or dry wells and the downspout trap and clean out of the present invention eliminates the problem. The device comprises a simple vertically movable tubular member, the upper end of which receives the lower end of the downspout and the bottom end of which is engaged in the drain line, the device being provided with an intermediate screen. In normal position it rests in the end of the drain line or in an adapter therein and in telescopic relation to the downspout. In such position it will collect the debris and prevent it from entering the drain line. It may be simply moved up the downspout in telescopic relation so as to free its lower end from the drain line whereupon it can be removed from its normal position and the debris emptied and the device replaced.
