WATER-STRAINER.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed November 5, 1907. Serial No. 400,778.

To all whom it may concern:

Be it known that 1, JOHN O. OLsoN, a citizen of the United States, residing at Red Wing, in the county of Goodhues and State of Minnesota, have invented a new and useful WaterStrainer, of which the following is a specification.

This invention relates to a combined filter and cut off for down spouts and has for its object to provide a comparatively simple and inexpensive device of this character by means of which the rain water from a roof or watershed may be discharged into a waste pipe or directed into a suitable cistern for future use.

A further object of the invention is to provide the cut off with a plurality of superposed screens one of which is inclined laterally for discharging foreign matter on opposite sides of the casing thereby to prevent clogging or otherwise ob structing the out off.

A further object is to form the casing or housing with laterally extending wings which constitute wind guards.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will ap pear in the following description, it being understood that various changes in form, proportions and minor details of construc tion may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a perspective view of a combined filter and cut off constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is a similar view taken on the line 44 of Fig. 2.

responding parts in all of the figures of the drawings.

The improved device forming the subject matter of the present invention includes a casing or housing 5 provided with spaced discharge pipes 6 and 7 one of which is connected with a cistern while the other discharges into a suitable waste pipe or sewer.

Extending vertically from the upper portion of the casing 5 is an inlet pipe 8 for attachment to the down spout of a roof or leaves, twigs and otherwatershed, said pipe being provided with spaced depending plates 9 defining oppositely disposed openings or recesses 10 and having their lower ends soldered or otherwise rigidly secured to a flange 11 extending vertically from the casing 5, as shown. Formed in the plates 9 are oppositely disposed notches 12, the metal forming the plates being bent laterally at said notches to produce inwardly extending supporting flanges 13.

Interposed between the plates 9 and resting on the flanges 13 is a screen 14 of relatively coarse mesh, the central portion of the screen being disposed at the center of the inlet pipe 8 and the opposite ends thereof inclined downwardly and connected to the upper edge of the flange 11 so as to discharge deposits of leaves, twigs or other foreign matter through the recesses 10 and thus prevent clogging or otherwise obstructing the cut off.

Disposed beneath the screen 14 and fastened in any suitable manner to the interior walls of the flange 11 is an auxiliary screen 15 of relatively fine mesh which serves to remove small particles of foreign matter passing through the upper screen so that the wa ter will be thoroughly filtered prior to its discharge into the cistern.

Slidably mounted for vertical movement on the inlet pipe 8 is an adjustable collar 15 having downwardly inclined wings 16, which latter constitute wind guards and serve to prevent the wind from blowing the water laterally through the openings 10 and diverting the flow of water through the pipes 6 or 7. The collar 15 is locked in adjusted position by screws or similar clamping devices 16 which pierce the collar and bear against the exterior walls of the inlet pipe 8, as shown. It will thus be seen that by releasing the screws 16 the collar together with the wind guards may be adjusted vertically of. the inlet pipe so as to permit the removal of leaves or other deposits should the latter happen to lodge between the screen and said wind guards.

The auxiliary screen 15 is preferably reinforced and strengthened by the provision of a transverse rod 17 which bears against the central portion of the screen 15 and serves to prevent the latter from sagging when sub jected to excessive weight.

J ournaled in the walls of the casing 5 at the juncture of the pipes 6 and 7 is a transverse shaft 18 to which is secured a troug or plate 19 for deflecting the water from down spout through the pipe 7 to the cistern or through the pipe 6 to a sewer.

Secured to the exterior walls of the casing 5 is a metal strap or wire 20 bent to form spaced locking notches 21 adapted to receive the terminal handle 22 of the pin or shaft 18 thereby to lock the trough or deflector in adjusted position.

In case of a rain fall the deflector 19 is tilted so as to discharge into the pipe 6 thus permitting the first flow of water from the roof or water-shed to pass through the cut off into the sewer or waste pipe. The out off 19 is then tilted in the opposite direction so as to discharge the water into the cistern. As the water enters the pipe 8, leaves, twigs and other foreign matter carried along by the water will strike the screen 14 and thence be deflected laterally through the recesses 10 on the opposite sides of the casing, in the manner before stated.

From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and efficient device admirably adapted for the attainment of the ends in view.

Having thus described the invention what is claimed is:

1. A device of the class described includ ing a casing having discharge pipes and provided with an inlet pipe having oppositely disposed recesses formed therein, a deflector pivotally mounted in the casing, a screen disposed within the inlet pipe at said recesses, and vertically adjustable wings extending laterally from the inlet pipe and constituting wind guards.

2. A device of the class described including a casing having discharge pipes, a cut off pivotally mounted for tilting movement at the juncture of said pipes, an inlet pipe secured to the casing and provided with oppositely disposed recesses, flanges extending inwardly from the inlet pipe at said recesses, a screen supported on the flanges, and vertically adjustable wings disposed at said recesses and constituting wind guards.

3. A device of the class described including a casing having spaced discharge pipes and provided with a vertical flange, a screen extending transversely across the casing and secured to said flange, a cut oil pivotally mounted within the casing at the juncture of the discharge pipes, an inlet pipe extending vertically from the flange and provided witlr oppositely dis osed recesses, flanges extending inwardly rom the walls of the inlet pipe at said recesses, a second screen resting on said flanges and having its opposite ends inclined downwardly and projected laterally the 1 between the walls of said recesses, and wings disposed at the inclined ends of the screen and constituting wind guards.

4. A device of the class described including a casing having spaced discharge pipes, a shaft extending transversely through the casing at the juncture of the discharge pipes, a trough secured to the shaft, a metal strip secured to the exterior walls of the casing and provided with oppositely disposed looking recesses, a crank secured to one end of the shaft and adapted to engage the notches for locking the trough in adjusted osition, an inlet pipe extending vertically Tom the casing and provided with oppositely disposed recesses, a screen arranged within the inlet pipe and having its opposite ends projected laterally between the walls of the recesses, a collar mounted on and adjustable vertically of the inlet pipe, and inclined wings carried by the collar and constituting wind guards.

5. A device of the class described including a casing having spaced. discharge pipes and provided with a vertically disposed flange, a screen extending transversely of the casing and secured to said flange, a transverse reinforcing bar bearing against the screen, a cut off pivotally mounted at the juncture of the discharge pipes, an inlet pipe secured to the flange and, provided with oppositely disposed recesses, a second screen arranged within the inlet pipe, a collar slidably mounted on the inlet pipe and provided with laterally extending wings constituting wind guards, and means for clamping the collar in adjusted position.

6. A device of the class described including a casing having spaced discharge pipes and provided with a vertically disposed flange, a screen secured to the flange and inclined downwardly in opposite directions, a cut off pivotally mounted at the juncture of the discharge pipes, an inlet pipe secured to the casing andprovided with spaced depending plates defining oppositely disposed recesses, the walls of said plates being formed with notches and the metal constituting the plates bent inwardly at said notches to form inclined flanges, a second screen disposed within the inlet pipe and resting on said flanges, and wings extending laterally from the casing at said recesses and constituting wind guards.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
