DRAINAGE DEVICE FOR ROOF GUTTERS AND THE LIKE Filed May 51. 1929 5 Sheets-Sheet 5 INVENTOR ATTORNEY Patented June 23, 1931 UNITED STATES PATENT OFFICE ROBERT MCKEE, OF PHILADELPHIA, PENNSYLVAN DRAINAGE DEVICE FOR ROOF GUTTERS THE LIKE Application med May 31,

It is well known that roof gutters clog up, due to leaves and other foreign matter, thereby allowin no way for the rain water to p drain off. ometimes thestoppage is caused by rags, paper and any foreign material that will not pass through the drain pipe leading from the gutter.

Therefore the present invention relates to an improved drain device to be inserted in the drain pipe and located between the opposite walls of the roof gutter.

The purpose of the invention is to provide a cage comprising a multiple of stays, arranged in cylindrical formation, withtheir lower ends free and unattached, therefore yieldable, to permit the drain device to be inserted in the drain pipe, hence. adapted to be sup orted in different positions, slightly above t e margin of the outlet end of the pipe,

' in order to allow the water to drain off. The

stays prevent foreign matter such as leaves and the like from passing through.

Another purpose is to provide an improved drain device having an outer abutment ring, with a plurality of inner rings in spaced positions and graduated, in order to carry ofl the rain water. at different levels in the gutter, the stays of the cage above the abutment ring acting to prevent the passage of foreign matter through the drain pipe.

' A still further purpose is to provide an apex cap at the top of the cage for retaining the radial bent ends of the stays in position, the apex cap in one instance, as shown in the drawings, having a depending cylindrical wall disposed in spaced concentric position with the uppermost ring member, so that should small particles of refuse stop up the spaces between the .various concentric 1929.

trically spaced rings, so th be fastened to each other.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

Figure 12 is a. cross sectional View on line 1212 of Figure 11.

Referring to the drawings, 1 identifies a pit-ch roof, 2 the gutter, 3 the cornice and 4 the drain pipe, while in Figure 2 the roof 5 is approximately flat, which may be either tin or slag. Though there are two forms of roofs, the roof gutter in both instances are identified by the same numeral, and so is the drain pipe.

Adapted to be arranged in the drain pipe is a drain device 6, which in every instance comprises a cage 7 made up of stays 8, except ing in Figure 10 where the cage merely extends halfway of the device. The stays 8 are constructed of sheet metal, that is in strips. For instance each strip is bent longitudinally upon itself, the'bent portions being folded over to insure rigidity, and the stays are secured to a base abutment ring 9, which is also made of sheet metal, in a strip and bent longitudinally upon itself, as shown in the sectional views. The cross sectional construction of the stays is disclosed in the cross sectional views 5 and 7.

The stays extend above and below the abutment base ring, the lower portions acting to engage within the drain pipe, the drain device being capable of adjustment to different heights, so that the drainage of rain water may take place below the abutment ring. However the abutment ring may rest on the bottom of the roof gutter as shown in Figure 2.

Arranged within the cage is a plurality of rin 10, which are concentric with each other and suitably spaced. The rings are disposed in gradually increasing heights, so as to appear in conical formation within the cage, the different heights being for the purpose of draining off rain water at different levels. It is obvious that when the drain device is first applied to a drain pipe therain water will drain off at all times at a lower level. However should the first space become clogged, then the second space between certain of the rings will carry the rain water off, and should the second space become clogged, the third space will carry off the water and so on throughout the height of the cone.

In order to support the innermost rings 10, they are provided with lateral lugs 11, which are struck up from the rings themselves, as shown at 12. Theselugs are in turn soldered or electrically welded to adjacent rings, as shown clearly in Figures 4, 5 and 7. However the larger rings 13 at the bottom are fastened to the inner faces of the stays by any well known means, for instance soldering or electrically spot welded to .the inner faces of the stays, at a point adjacent the abutment ring 9.

The upper parts of the stays are bent at 14L and are radially inclined tothe cage, and as in Figures 3 and a the terminals of the inwardly bent portions 15 are fastened by soldering or electrically spot welding at 16, to an apex cap 17.

As in Figures 1, 3 and 4 the apex cap 17 is in turn fastened by soldering or spot welding to a cylindrical Wall 18, which depends into an adjacent ring.

In Figures 2, 6, 8, 9 and 11 the inwardly turned parts 15 of the stays are soldered or spot welded between inner and outer apex caps 19 and 20, therefore further insuring rigidity.

The lower parts of the stays are more or less yieldable, so as to engage within the drain pipe frictionally, in order to hold the cage in different positions.

Also in Figures 6, 8, 9, 10 and ll-the several innermost rings vary in number, which is more or less a matter of choice as tohow many rings the present type of drain device may possess.

In Figure 10 the construction of the drain device is more or less modified as compared with the other drain devices, in that the stays extend down from the larger base ring 21, while the upper part of the drain device is entirely opened, that is on the sides adjacent the various rings forming the conical part of the drain device.

The upper part of the drain device in Figure .10 has the apex cap 22 supported on the smaller upper ring 23 by means of supporting arms 24:. The supporting arms are soldered or spot welded or otherwise fastened to the ring 23.

The various lugs for mounting and supporting the several rings in position are struck up from the rings at various locations, so that all the lugs will not align in a radial direction.

In Figures 1 to 12 inclusive the various inner rings or members; that is, whether circular, rectangular or otherwise formed, are arranged at gradually increasing heights and are operatively supported within the cage and spaced in conformity with each other. The spaces between the plurality of rings or members constitute passages for rain water.

As previously stated the rain water will drain oil at different levels, accordingrasthe spaces between the rings may clog up.

The invention having been set forth, what is claimed is:

1. A drain device for roof gutters and drain pipes, comprising a cage having depending yield able-stays, which engage within the drain pipe, said cage having an apexcap supported at the top of the device, a plurality of cylindrical concentricspaced rings operatively supported within the cage at gradually increasing heights, thereby arranging the rings in conical formation.
