WATER SCREENAND FILTER.

SPEGIFIGATIONforming part of Letters Patent No. 748,230, dated December 29, 1903.

Application filed July 31, 1903.

To all whom it may concern:

Be it known that I, STEPHEN STOUT, a citizen of the United States, residing at Axtell, in the county of Marshall and State of Kansas, have invented a new and useful Water Screen and Filter, of which the following is a specification. I

This invention relates to water-filters, and particularly to the type designated as service-pipe filters.

The principal object of the invention is to provide means for efficiently cleaning the filter and for generally improving the construction thereof.

Other objects and advantages of this invention will be specifically described hereinafter and the novel details of construction of the preferred embodiment of the device will be specifically described in the following description, reference being had to the accompanying drawings, in which Figure 1 is a vertical longitudinal sectional view of a filter constructed in accordance with my invention. Fig. 2 is a detail perspective view of the collector and screen, and Fig. 3 is a cross-sectional view through the screen and the supporting means.

1 designates the outer shell or casing, illustrated as being substantially cylindrical and supported upon suitable standards 2. The bottom 3 of the casing is substantially conical to direct the liquid toward the vertex thereof and into the discharge-pipe 4:. The filtering-bed 5 consists of suitable granular material, which is packed within the receptacle 1 and is supported above the opening in the bottom of the receptacle by a gratefi, so that the water will not direct it into the dis:

charge-pipe 4. A screen 7 is fitted within the receptacle and rests above the filteringbed, so as to confine the material between it and the grate, whereby accidental displacement thereof will be prevented.

Positioned above the filtering-bed is a separator 8, which is provided with a collectingpan 9, coinciding in The collecting-pan 9 is provided with a circumferential flange 10, having an annular groove 11, within which is a packing 12. The edge of the flange may form withthe shape of be notched, as at 13, l

Serial No. 167,778. (No model-J to receive one end of the packing-strip,which will then be wound around the flange and rest within the groove ll. The pan rests upon and is supported by an intermediate circumferential inwardly-disposed bead 14, .formed in the receptacle,

so that when the pan is forced down within the receptacle the bead will constitute a seat therefor.

Thescreen is preferably pyramidal in form and is shown as surrounding a central open ing 15 in the bottom of the collecting-pan 9. The corners of the screen are braced by the converging bars 16, which connect at the apex of the screen and enable said screen to withstand any pressure due to the introduction of the water into the receptacle through inlet-pipe 17, carried by the removable cover 18. The braces 16 also serve as intermediate connections between the ring 19 and the pan, so that a sufficient pull upon the ring will effeet the removal of the pan. It will be observed that the pan and screen are constructed together, so that one acts as a brace for the other, and thereby providing cousiderable strength to the entire structure.

In actual practice the panels 20 of the screen 8 will be attached to the braces 16by inserting the edges of the panels in grooves in the braces, after which the edges of the braces are erimped over the edges of the panels to secure them.

All of the parts being assembled, water is admitted into the filter through the inlet-pipe 17 so that it will strike the apex of the screen and beseparated or deflected to pass through the panels and through the filtering-bed into the discharge-pipe 4. The coarser particles of extraneous matter will pass over the screen and be deposited into the collectingpan,

while the finer particles will be carried by the water through the mesh of the screen and separated by the filtering-bed before the water finally passes out through the dischargepipe 4. 1

When desired, the top of the receptacle can be removed and the screen and collectingpan may readily be detached, so as to relieve the filter of the collected impurities, and, if

desired, the filtering-bed can also be cleansed by taking out the screen 6.

Inasmuch as the screen-panels are disposed at substantially a vertical plane it will be impossible for the meshes to become clogged by leaves, &c., so that a free passage of the water through the screen will at all times be assured.

It will be seen that the device is eflicient, durable, and easy to assemble.

I claim 1. In a filter, a casing, a separator fitting in the casing and comprising a pan having a central opening an upstanding flange peripherally disposed and a part of the pan and having a groove, with a notch in the flange, a packing engaging the notch and seated in the groove and ascreen covering the opening and having upstanding converging panels.

2. In a filter, a casing, a separator fitting in the casing and comprising a collectingpan, having a groove provided with a notch in the edge of the pan, a packing in the groove one end of which engages the notch, and a screen carried by the pan.

3. In a filter, a casing, a separator fitting in the casing and having a peripheral flange with a circumferential groove and a notch in the flange, and a packing in the groove, one end of which engages the notch.

4. In a filter, a casing containing a filtering-bed, and a collecting-pan above the bed having a groove and a packing in the groove frictionally engaging the casing.

5. In a fiter, a casing having an inverted conical bottom, a discharge pipe leading I STEPHEN STOUT. Witnesses:
