4 Claims. 1

This invention relates to sheet metal downspout shoes or elbows, and is more particularly concerned with the construction of the discharge ends of such elbows or shoes.

The primary object of the invention is to provide a downspout shoe of simple and inexpensive construction having a strongly reinforced discharge end so constructed as to assure substantially complete discharge of water therefrom whereby to prevent rusting at said discharge end of said shoe.

A further object of the invention is to provide a downspout shoe having a discharge end which is radially outwardly offset and comprises an outwardly turned reinforcing double flange.

Other and further objects of the invention will become apparent as the description proceeds, reference being made to the accompanying drawings forming a part of the present disclosure, wherein:

Fig. 1 is a side elevational view, partly in section, of one form of downspout shoe constructed in accordance with the teaching of my invention;

Fig. 2 is a fragmentary plan view of the sheet metal blank from which my downspout shoe is constructed, after the said blank has been notched;

Fig. 3 is a fragmentary plan view of the said blank after the margin thereof adjacent the notch has been folded rearwardly and forwardly to provide one form f the double flange;

Fig. 4 is a fragmentary sectional view taken in the plane of the line 4--4 of Fig. 3; and

Fig. 5 is a fragmentary sectional view illustrating a modified form of the double flange.

Referring in detail to the drawings, wherein for purposes of illustration the preferred embodiments of my invention are shown, the numeral I designates generally a downspout shoe or elbow of unitary construction and constructed in accordance with the teaching of my invention, and Fig. 1 illustrates the same connected to a downspout 2, illustrated in dotted lines, whereby to direct water flowing through the downspout away from the building to which the downspout is connected.

The discharge end portion 3 of the downspout shoe 1 is of a particular construction designed to strengthen and reinforce the same and also to provide for complete discharge of water therefrom, i. e., there are no recesses, grooves, walls. etc, in which or behind which water may collect and not drain.

As clearly illustrated in Fig. 1, the said discharge end 3 is folded or doubled back and forth upon itself and pressed to provide overlapping, rearwardly and forwardly directed reinforcing

flanges

4 and 5 which may be considered to be a double flange providing a triple thickness of metal. In addition, to further reinforce and strengthen this end portion of the shoe, the flanged end 3 thereof is offset radially outwardly to provide a larger outlet as indicated at B. It will be observed that in addition to its reinforcing function, the offset portion '6 provides a drop for the water flowing through the shoe adjacent the discharge end thereof, and said drop functions to increase the velocity of the Water at this point to aid in its complete discharge.

The free edge 1 of the flange 5 is preferably spaced slightly from the discharge edge 8 of the discharge end 3 whereby to assure a discharge edge free from burs and also to minimize the tendency for water to seep between the

compressed flanges

4 and 5. Thus, as illustrated, the water will tend to drop from the rounded edge 8 to the ground rather than travel rearwardly along the flange 4 to the outer end of the flange 5.

The modified form of discharge end construction 3' illustrated in Fig. 5 differs from the discharge end 3 only in the way the flanges are folded. In this instance, the rearwardly directed flange 4' is positioned outside rather than inside the forwardly directed fiange 5 thereby providing a double flange construction as before, but with the free edge I of the flange 5' completely enclosed. This construction provides an entirely smooth and rounded discharge edge 8, and posi tively eliminates any possibility of the discharged water seeping between the flanges.

In making my downspout shoes from sheet metal, the sheet metal is first out to form a rectangular blank. The blank I is then notched at one corner 9 thereof as illustrated in Fig. 2. The next step is the folding operation.

In making the downspout shoe illustrated in Figs. 1, 3 and 4, the end margin ID of the metal adjacent the notch is first folded rearwardly along the dotted line H, Fig. 2, and then forwardly along the dotted line I2, to provide the

double flange

4, 5 as illustrated in Figs. 3 and 4.

In making the downspout shoe illustrated in Fig. 5, the end margin ID of the metal is first folded rearwardly along the dotted line I2, and then folded rearwardly again along the dotted line I I to provide the double flange 4', 5.

The next step following either of the above described folding operations is to compress the flanges and simultaneously outwardly offset the discharge end portion 3 or 3'. This operation is performed by passing the said end portion between properly shaped rollers,

Subsequent to the compressing and offsetting operation which leaves the blank in a substantially rounded condition, the blank is bent to form an elbow.

The notch 9 provides a side margin l3 for overlapping the other side margin I4 with the ends of the double flange positioned in abutting relationship and thenext step is to secure the overlapped marginal sides together, either by cleating, welding, soldering, or in any other well known manner.

As illustrated in Fig. 1 (by the absence of crosshatching) the ends of the double flange preferably abut at the top of the shoe along a vertical plane passing through the axis thereof,

rorn the foregoing it will be obvious that I have provided a downspout shoe which is simplein construction and cheap to manufacture, and which provided with a dischargeend of smooth, rigid construction, and free of objectionable Water trapping recesses, grooves, walls, etc.

I claim:

1. In a sheet metaldownspout shoe or elbow of unitary construction, an outwardly offset discharge end portionysaid discharge end portion comprising an outwardly turned double flange, thereby providing a triple thickness of metal at said discharge end: portion, and said discharge end portion being compressed, whereby provide said downspout shoeor, elbow with a strongly reinforced discharge end portion free from water trapping means.

2. In sheet metal downspout-shoe or elbow of unitary construction, an outwardly oilset discharge end portion, said discharge end portion comprising outwardly turned, rearwardly and forwardly directed, overlapping flanges, thereby providing a triple thickness of metal said discharge end portion, said discharge end portion being compressed, whereby to provide said downspout shoe or elbow with a strongly reinforced discharge end portion free from Water trapping means.

3. The structure set forth in claim 2, characterized by said forwardly directed flange being positioned outwardly of said rearwardly directed flange, and said forwardly directed flange having a free edge spaced rearwardly of the discharge edge of said discharge end portion.

4. The structure set forth in claim 2, characterized by said forwardly directed flange having a freeedge and positioned inwardly of said rearwardly directed flange, whereby to enclose said free edge of said forwardly directed flange.
