fz/GENE @A Us cf/ www@ ATTORNEYS Patented May 6, 1952 UNITED STATES DOWNSPOUT STRAINER Ohio Application August 8, 1950, Serial No. 178,264
My invention relates to a downspout strainer. It has to do, more particularly, with a strainer or trap for use in a downspout or similar pipe to permit free passage of water but to catch or traps leaves, twigs, et cetera, which tend to clog sewer lines.
One of the objects of my invention is to provide a strainer or trap of the general type indicated which is located in the downspout so that it can be reached from the ground level, thereby eliminating the necessity of removing and cleaning the usual strainers which are located in the gutters and which are usually so high that ladders are required to reach them.
Another object of my invention is to providev a strainer or trap which is easily accessible and which can be removed easily from the downspout for dumping the leaves and trash therefrom.
Another object of my invention is to provide a downspout strainer which is so designed that it will not interfere with the normal water flow through the downspout and will not normally allow leakage of Water from the downspout adj acent the strainer.
Still another object of my invention is to provide a downspout strainer or trap of the type indicated which includes a strainer member that can be removed readily when it deteriorates and be replaced with a new one. Y!
Another object of my invention is to provide a downspout strainer or trap arrangement which is simple and inexpensive and can be readily mounted on the usual sheet metal downspout pipe.
Various other objects will be apparent.
The preferred embodiment of my invention is illustrated in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:
Figure 1 is a perspective view showing my device mounted on a downspout.
Figure 2 is a vertical sectional view through a downspout showing my strainer in normal operating position therein by full lines and by dotted lines in a position to permit removal and emptying of the strainer.
Figure 3 shows the U-shaped wire which supports the strainer.
Figure 4 is a diagrammatic View illustrating how the strainer can be located in a readily accessible position in the downspout.
With reference to the drawingal have illusstrated my device as comprising a section of sheet metal pipe Iii which is of the same size as the downspout with which my device is to 3 Claims. (Cl. 210-99) be associated. The section IB has slidably mounted thereon for axial movement a sleeve II. The pipe section io is provided with an elongated slot or opening I2 which extends onehalf of the circumference of the section Iil. The axially movable sleeve II is of suicient length to completely close the opening I2 when in one position which is determined by a stop lip I3 formed at one end of the opening I2. It can be slid in the opposite direction to practically completely expose the opening I2.
Connected to the end of the sleeve Il -which is adjacent opening I2 is a U-shape wire or rod ifi. This wire, which is shown best in Figure 3, has its outturned ends I5 snapping into diametrically opposed openings I6 in the sleeve Ii. These outturned ends I 5 will limit sliding movement or sleeve II in opening-uncovering direction by contact with the end of opening I2, as shown by dotted lines in Figure 2.
The lower transverse portion Il of wire I4' is adapted to removably support a strainer I8. This strainer i8 is preferably of wire mesh and is provided with a pair of inverted U-shape clips I9 on its bottom which will straddle transverse portion I'I of wire I4. The strainer I8 is preferably of inverted irusto-conical form to facilitate insertion into the pipe section II). The strainer I8 Will be of less axial length than the openingr I2 to permit passage therethrough.
As pointed out above and as illustrated in Figure 4, the strainer arrangement may be located in the downspout D in a convenient location readily accessible from the ground level.
The position of strainer I8 in normal use is shown by full lines in Figure 2. In this position, the strainer I8 will be located well below opening I2 and sleeve II will completely cover the opening, its downward position being determined by the outturned lip I3. In this position, strainer I8 will permit downward passage of water but catch leaves, twigs and other trash. Also, opening I2 will be sealed. When it is desired to remove the trash, the sleeve II is moved vertically on section I0. The sleeve is moved to its uppermost position, shown by dotted lines in Figure 2 and determined by portions I5 of wire Il contacting with the upper end of opening l2. In this position of sleeve II, relative to opening I2, strainer I8 will have its upper edge below the lower edge of sleeve II and its lower edge above the lower edge of opening I2. Thus, the basket strainer I8 can be swung outwardly about pivot II and can then be slipped axially oii the pivot. The trash can then be dumped from the basket strainer and the strainer can be replaced on the pivot I1 or a new basket can be substituted therefor. Then the sleeve I I is lowered to close opening I2 and return strainer I8 to its normal functioning position. As the strainer moves downwardly it is centered in pipe section I@ due to its inverted frusto-conical shape.
My device has many advantages some of which have beenspecically discussed and others of which will be apparent.
Having thus described my invention, what l claim is:
1. A strainer for use in a downspout comprising a pipe section of annular cross-section having an opening therein which extends one-half the circumference of the pipe section, a sleeve of greater length than said opening ntting around the pipe section and mounted for Inovement thereon into and out of covering relationship with said opening, the lower edge of the opening having an outturned lip which limits downward movement of the sleeve, strainer member of inverted frusto-conical form attached to said sleeve and movable axially therewith so that it will be opposite the opening when said sleeve is moved into opening-uncovering position, said opening being of greater length axially than said strainer member, said st ner inember being attached to said sleeve by lJ-shape wire which has its upper ends connected te said sleeve, said Wire having a transverse lo'l tion, and inverted U-shape clips on e bottoni of said strainer member which transverse portion.
2. A strainer according to claim 1 wherein said U-shape wire has outturned upper ends which snap into diametrically opposed openings at the lower end of said sleeve.
3, A strainer for use in a downspout comprisp cring a. pipe section of annular cross-section having an opening therein which extends at least one-half the circumference of the pipe section, a sleeve of greater length than said opening ntting around the pipe section and mounted for axial movement thereon into and out of covering relationship with said opening, the lower edge of the sleeve and the lower edge of the opening being provided with stop portions which cooperate to limit downward movement of the sleeve, a cup strainer member attached to said sleeve and movable therewith so that it will be opposite the opening when said sleeve is moved into opening-uncovering position, said opening being of greater length axially than said strainer member, said strainer member being attached to said sleeve by a U-shape wire which has its upper ends connected to said sleeve, said wire having a transverse lower portion, and inverted U-shape clips on the bottom of said strainer member which straddle said transverse portion.
