TL;DR: A repositionable downspout extension that is attached to a down spout to direct rainwater away from a building is described in this article, where the extension is a generally cylindrical body with first and second ends.
Abstract: A repositionable downspout extension that is attached to a downspout to direct rainwater away from a building. The extension is a generally cylindrical body with first and second ends. The extension comprises selectively removable adapter portions at each end that allow the extension to be connected to a downspout. An interlockable collar portion is at each end of the extension and interior to the adapter portions. The interlockable collar portions allow a number of the extensions to be connected together to form a downspout extension assembly after the adapter portions are removed. The extension further comprises an adjustable portion between the two collar portions. The adjustable portion comprises collapsible corrugations so that the extension can be bent into a number of positions and hold its position.
TL;DR: In this paper, a rain gutter which is formed of a one-piece sheet of material and includes terminal flanges is described. And the gutter top wall includes openings to allow moisture to be drained, while preventing entry of debris which could clog the gter and downspout.
Abstract: A rain gutter which is formed of a one-piece sheet of material and includes terminal flanges. A clip member secured to the building side wall includes a channel into which the gutter terminal flanges are restrictively fitted to suspend the gutter below the building roof. The gutter top wall includes openings to allow moisture to be drained, while preventing entry of debris which could clog the gutter and downspout.
TL;DR: In this paper, the authors proposed a downspout trap to prevent the debris from entering the footer drains and/or dry wells of a building by using a simple vertically movable tubular member, the upper end of which receives the lower end of the down spout and the bottom end engaged in the drain line.
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.
TL;DR: A debris removal device for rain gutter downspouts is inserted between the bottom of the downspout and the top of a ground drainpipe into which the down spout empties as discussed by the authors.
Abstract: A debris removal device for rain gutter downspouts is inserted between the bottom of the downspout and the top of a ground drainpipe into which the downspout empties The device comprises an elongate tubular housing open on both ends and having an unobstructed third opening formed transversely through the tubular wall between the ends A partition, having apertures formed therein, extends generally transversely within the tubular housing at an inclination converging toward the third opening so as to divert debris, which enters the tubular housing through the first opening, out the third opening while enabling rainwater associated with the debris to pass through the apertures in the partition and out the second opening Water flow guides associated with the partition divert rainwater away from the third opening to inhibit it from flowing out the third opening along with the debris A dam is provided at the bottom of the third opening to likewise inhibit the flow of water out the third opening
TL;DR: In this paper, a downspout water conservation diversion adaptor is provided for insertion within the lower part of an upstanding down spout and is selectively operable to divert water flowing downward through the down-spout laterally outwardly of the adaptor and along a building wall outwardly beyond which a roof eaves projects for irrigation of ground vegetation.
Abstract: A downspout water conservation diversion adaptor is provided for insertion within the lower part of an upstanding downspout and is selectively operable to divert water flowing downward through the downspout laterally outwardly of the adaptor and along a building wall outwardly beyond which a roof eaves projects for irrigation of ground vegetation disposed beneath the eaves. The adaptor is constructed to automatically bypass excess water flowing downwardly to the adaptor, in excess of that water which may be laterally outwardly directed from the adaptor, in a manner such that the excess water is discharged from the bottom of the downspout. Further, the adaptor includes a provision whereby, in the absence of rain, a garden hose or the like may have the discharge end thereof sealingly connected with the adaptor in order to supply irrigation water to the interior of the adaptor in a manner such that the irrigation water may be conveyed laterally outwardly of the adaptor and utilized for irrigating the same ground vegetation.
