DOWNSPOUT EXTENSION Filed Oct. 2, 1957 John Horn 1.\ VLN'I OK.

nited States This invention relates to an improved extension for the usual elbow at the lower end of a conventional downspout and has reference in particular to an extension which, when it is not in use, may be folded up against the downspout to assume an out-of-the-way position.

It is customary to employ troughs and extensions of one type or another at the discharge end, usually the elbow, at the bottom of a downspout. This is to direct or feed the water in a direction lateral to the perpendicular position of the downspout and to thus dispose of the water in a more satisfactory manner. Sometimes it is necessary to dispose of the water across a flower bed, or a sidewalk, and so on. In any event extensions for downspouts are old and well known. As a matter of fact, it is not new to provide an extension which is hingedly mounted.

The present invention relates to an improved construction which, it is believed, will better serve the manufacturing advantages and economies of manufacturers, will be endorsed by hardware men and retailers and roofers since the extension can be readily applied and will be fully appreciated by the home owner who finds an extension of this type desirable for his particular home needs.

In carrying out the principles of the invention, the extension takes the form of a length of tubing or downspouting and this may be of any prerequisite length. The end which is adjacent to the elbow is especially designed so that one wall is cut away to facilitate folding and to provide additional walls which may be hingedly bolted to the downspout.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Fig. 1 is a side elevation of the improved extension showing how it is constructed and used.

Fig. 2 is a similar elevational view of the same showing the extension in its downwardly disposed position.

Fig. 3 is a section on an enlarged scale taken on the line 3-3 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is an exploded perspective view showing the details more clearly.

Referring now to the drawings, the downspout is denoted by thenumeral 6 and is provided at its lower end with a more or lessconventional elbow 8, the discharge end portion of which is denoted at 10. The U-shaped spring metal orequivalent clip 12 is connected to the downspout at the desired position to hold theextension 14 in an up out-of-the-way position as seen in Fig. l.

The extension is of suitable length and material and may be said to be an appropriate length of tubing, the

atent discharge end of which is denoted at 16. The attachable and hingedly mounted end is denoted generally by thenumeral 18. As best seen in Fig. 4, an end portion of thetop wall 20 is cut away at 22 to define a pair of spaced parallel attachingwalls 24. Thebottom wall 26 is extended to provide a stabilizing or stop lip. This strikes against the bottom of the elbow to limit the downward swinging of the extension in the manner seen in Fig. 2. Abolt 28 extends through thebolt holes 30 in theside walls 24, the head of the bolt being denoted at 32 and the threaded end at 34 to accommodate thenut 36 and cooperatingwasher 38. Thenumeral 40 desig nates another washer and 42 designates a reinforcing and spacing sleeve which is fitted into theend 10 between thewalls 44 to provide a stable hinging connection. Thus, the cut-away attachable end portion of the extension is nicely hinged to the elbow and registers therewith in the manner seen in Fig. 2, or swings up and away from the elbow to an outof-the-way position as seen in Fig. 1.

Although extension troughs which are hingedly mounted are old in the art, it would appear to be novel in this line of endeavor to provide the special bolting means, the notched awaywall 22 and theextension walls 24 and the extendedend portion 26 providing a stop lip in the manner illustrated. Consequently, a construction is herein revealed which, it is believed, will meet with the expected needs of users.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those.

skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

The combination of a downspout including an elbow of rectangular cross-section on its lower end and an extension mounted on said elbow, said extension comprising: a tube open at its ends and including a top wall, a bottom wall and side walls straddling the free end portion of the elbow and pivotally connected thereto for mounting the tube thereon for swinging movement in a vertical plane, said top wall, at its inner end, terminating short of the corresponding ends of the side walls for clearing the free end of the elbow when the tube is swung upwardly thereon to inoperative position, the inner end portion of said bottom wall extending beyond the inner ends of the side walls and engageable beneath the elbow for supporting the tube in operative position, and a resilient clamp on the downspout engageable with the tube for releasably securing same in inoperative position said inner end portion of said bottom wall of the tube, when said tube is in inoperative position, extending vertically in spaced, opposed relation to the discharge end of the elbow for breaking the force of the water therefrom and deflecting said water downwardly.
