' s claims. (ci. 299-104) This invention relatesT to a water dispersiondevice and particularly to suchl devices adapted for association with the downspout of a building for distributingwater fromV the downspout over a substantial area of the adjacent ground surface.
Downspouts associated with buildings such as residences must make provision for disposingof the water that isv drained from the downspout,'and in mostinstances it is considered desirable to providef drain connections to a storm sewer. While this is done in many instances, there may be considerations which render such storm `sewer connection impossible. Thus, in many localities the storm sewer systems areoverloaded, and as a result connections from downspouts are forbidden, Whilein other instances the cost of providing such storm sewer connections from the downspouts may be consideredJ to bevtoo costly. Where storm sewer connectionsarenot provided for the downspouts of the building, it is usually the practice to discharge the water onto the ground adjacentl to the building and as is widely recognized', such direct discharge onto the ground tends to wash away the ground at and near the point where the discharged water lstrikes the ground- To remedy this conditionv one expedient that has been employed is the provision of a relatively large area of stone or concrete on the l ground as a splash block inthe path of the discharged water, but in; most locations adjacent residences, this expedient is not desirable because it detracts from the appearance of the adjacent lawn areas.
In view of the foregoing it is the primary object of the present invention to provide a water disposal unit adaptedfor association with the downspouts of a residence or the like and which is eifective to distribute water from the downspout over a relatively large area and in such a way that the ground or lawn surface will not be disturbed` by the discharged Water. More specically, it is an object of the present invention to provide such a unit in which `a normally coiled, exible water distributing member may be associated with a downspout in such a manner that when water iiows downwardly in the downspout, the pressure head of such water is eiective to uncoil a distributing member onto the adjacent ground surface so that the water from the downspout will be sprinkled over the area with a gentle spraying action so as to avoid disturbing the ground surface.
Other and related objects of the present invention are to afford such a water dispersion unit that may be readily associated with downspouts of the longitudinally corrugated type, to enable such unit to be fully drained after ithas returned to its coiled normal position, and to alford a unit lof the aforesaid character that may be economically manufactured and sold and which may be associated with a downspout in a simple manner.
Other and further objects of the present invention will be' apparent from the following description and claims, and are illustrated in the accompanying drawings, which by way of illustration, show preferred embodiments of the present invention and thev principles thereof, and what I- -ew consider to be the best modein'which'I haveV contemplatedapplying these principles. Other embodiments of the invention embodying the same or equivalent principlesmay be used and structural changes may be made as desired by those skilled in the art without departing from the invention.

For purposes of disclosure the invention is herein illustrated as embodied in a water dispersing and distributing unit i0 which comprises an elongated, normally coiled sprinkling member 11 that may be mounted on the lower end of a downspout 12 so as to normally assume the compact coiled relationship shown in Fig. l, but which when subjected to the pressure head of water coming down the spout 12, is automatically extended or uncoiled to the relation shown in Fig. 2 so that the sprinkling member extends for a substantial distance along the ground Surface. In this extended or operative relationship of the sprinkling member 11, the water from the downspout will be distributed or dispersed with a gentle spraying action over a substantial area, thus to avoid washing away of the ground by the discharged water, `and when the flow of water stops, the reduction or removal of the pressure head permits the sprinkling member 11 to return to its normal coiled relation of Fig. l.
In the form of the invention shown in Figs. l, 2, 3, 4 and 5 the elongated sprinkling member 11 is hollow and relatively at in form and is made from a exible material such as a plastic, rubber, or rubberlike material to provide a substantial passage area through which water may ow longitudinally of the member l1. Thus, as illustrated specifically in Fig. 3 of the drawings, the member 11 has a pair of tubular elements IIL and 11R between which a central rectangular tubular member 11C is formed in an integral relation. The central tubular member 11C serves to house coiling means that act yieldingly to urge the sprinkling member 11 toward its normal coiled relation of Fig. l. Such coiling means as shown in Fig. 3, comprises a flat spring steel band 14 extended through the passage or tubular member llC and having a normally coiled relation or form. Thus, the coiled band 14 normally tends to coil the Vsprinkling member 11.
The free end of the sprinkling member 11 is so formed that water cannot discharge freely therefrom, and as herein shown this free end is fully closed as by an end clamp l5, Fig. 2.
The spray-like distribution of the WaterV from the sprinkling member 11 is attained by providing a large number of relatively small discharge or spray openings 16 in what amounts to the upper surface of the tubular members 11R and 11L, as shown in Figs. 2, 3 and 4, it being noted that when the sprinkling member 11 is" in its coiled relation of Figs. l and 4, these openings 16 are in the surfaces of the member 11 that face the center of the coil. i
At its other or mounting end the sprinkling member 11 has coupling means whereby the unit 10 may be operatively connected to the lower end of the downspout 12,. Such coupling means as herein shown comprise a hollow tapered transition member 18,` molded from a material such as that used for the member 11, so as to be somewhat funnel-like in shape land having its lower 'end joined to the member 11 so that water may ow through the member 18 and into the tubular elements 11L and 11R. If desired, the adjacent end'of the central passage 11C may be sealed as at 19 so as to protect the coiling member 14 from water.
The upper end of the transition member 18 is formed so that it may be slipped over the lower end of the downspout 12, and to enable this upper end to be clamped in a sealed relation to the usual` corrugated type of downspout, the upper end of the member 1S is formed with a thick resilient collar 18C which may be compressed into such corrugations by a ring-type clamp 20 and its clamping screw or bolt 20S, as shown in Figs. 4 and 5. This assures a tightly sealed relationship between the downspout 12 and the dispersing unit 10 so that the pressure head of water in the downspout 12 will be effective upon the unit 10 to extend the same when the necessity ar1ses.
The etective longitudinal passage area of the sprinkling member 11 is preferably substantially equal to the passage area of downspout, and the total elfective area of the spray openings 16 is also substantially equal to the downspout area,` and this relationship assures that the distributing capacity of the unit 11 will be such as to take care of the maximum water flow from the downspout.
This relationship may however be varied to a considerable extent, as desired, for it will be evident that the advantages of the present unit will be attained in a large measure even where its distributing capacity is occassionally exceeded.
Where higher emergency capacity is required, this may be provided by making the tubular members 11L and 11R of an easily stretchable material so that when unusually high pressures are built up due to an excessive runoff rate of water from the roof, the members 11L and 11E` will be distended, thus to increase the size of the openings 16 with a corresponding increase in the rate of water dispersion.
In the use of the dispersing unit 10, the resilient coiling means 14 is effective normally to maintain the sprinkling member 11 in its coiled, out of the way relation of Fig. l wherein it presents a neat appearance and is fully withdrawn from ground contact so that it will not cause discoloration of the lawn surface and will not interfere with the lawn growth. When, however, water drains from the building roof through the drain pipe 12, it will gather within the coiled member and in the connector 18 until a suicient pressure head is established in the drain pipe 12 to overcome the coiling forces exerted by the spring member 14, and at this time the sprinkling member 11 will start to uncoil and to extend itself away from the building toward the relationship of Fig. 2. While the forces exerted by the pressure head of water, and the weight of the water in the extended member 11 remain suicient to overcome the coiling forces exerted by the coiling member 14, the member 11 will remain in its extended position and will distribute the water with a gentle sprinkling action over a relatively large area.
When the flow of water decreases, the forces tending to maintain the member 11 extended gradually decrease,
and when such forces become insuicient to overcome the coiling forces of the member 14, the member 11 will be returned to the coiled relation of Fig. l. As such coiling progresses most of the water will be discharged from the member 11 through the openings 16, but as the final coiled relation is reached some water within the lowermost portion of the member 11 will be located below the level of the lowermost openings 16. To eiectually drain this nal portion of the water from the coil, a. small drain opening 21. is preferably provided in the bottoms of each of the tubular members 11L and 11R, and at the lowermost point of the coil, as shown in Fig. 4.
The means for exerting coiling forces on the member 11 may take different forms, and one such alternative form of sprinkling member 111 is illustrated in Fig. 3A of the drawings. Thus, a central strip 111C of solid cross section is formed from a resilient material such as plastic or rubber so as to normally assume a coiled relation, and tubular members 111R and 111L are joined as by vulcanizing or other bonding processes to opposite sides of the strip 111C so as to be coiled thereby. The tubular members 111K and 11.1L have sprinkling openings 116 formed in their upper surfaces, and the member 111 is associated with the other elements of the dispersing unit in the manner hereinbefore described.
As pointed out hereinabove, downspouts are made in different cross sectional shapes, such for example as the rectangular shape embodied in the downspout 112 shown in Fig. 5A. In such an instance the upper end of the connector 18 may be stretched into position about the lower end of the rectangular downspout 112 and may be clamped in position thereon by a two-part clamp 120 having a pair of clamping screws or bolts 120S at the opposite corners.
In Figs. 6 and 7 of the drawing another alternative embodiment of the invention is illustrated wherein a disu persing unit 210 is associated with a drain spout 212 and has an elongated sprinkling member 211 that is formed from a exible material such as plastic or rubber so as to have a somewhat oval cross sectional form. The sprinkling member 211 is sealed or substantially sealed at its free end by means such as a clamp 215, while at its mounting end it has connecting means including a funnel-like transition member 218 and a sealing band 218C that may be connected to the down spout 212 by a clamp 220 and clamping bolt 2208 in the manner hereinbefore described. The sprinkling member 211 has upper spray openings 216, and a tinal drain opening 221 that are formed and located in the manner hereinbefore described in connection with Figs. 1 to 4.
In the embodiment of the invention shown in Figs. 6 and 7, the coiling forces are applied to the sprinkling member 211 by coiling means located externally thereof, and such coiling means comprise a helically wound spring 214 which in itself tends to assume a spirally coiled relation. The spring 214 is placed about the sprinkling member 211, and is extended upwardly about the tapered connecting member 218, as shown in Figs. 6 and 7 so that the coiling tendency of the spring 214 normally rolls the sprinkling member 211 into the coiled form shown in Fig. 6. The upper end of the spring 214 is preferably anchored as by bending the end over the clamp 220, as indicated at 214B in Fig. 6. The dispersing unit 210 operates in the same advantageous manner as the previously described structures.
From the foregoing description it will be apparent that the present invention provides a water dispersing unit that may readily and easily be associated with a downspout to disperse the drained water with a gentle sprinkling action over a substantial adjacent lawn area or the like, thus to avoid objectionable washing away of the earth near the downspout. It will also be evident that the automatically attained extension and retraction of the sprinkling element of the unit produces a normal appearance` that is attractive, and also enables the normalaai/gesso growth of the lawn to be attained. Moreover, the dispersing unit of the present invention is capable of manufacture and sale as an independent item of merchandise, and may be installed by purchaser.
Thus, while I have illustrated and described preferred embodiments of the invention, it will be understood that these may be varied by those skilled in the art without departing from the spirit and scope of the appended claims.
