1 METHOD FORMING SCREEN PLATE.
Application filed March 22, 1927, Serial No. 177,403.
My invention relates to screens, particularly those used for supporting granular material in filters and water softeners.
It is the object of my invention to provide 5 a screen for supporting granular material which will prevent the entrance of material into and through the material distributing said fluid which atthe same time prevents the fine, granular material from making its exit through the screen.
Referring to the drawings:
Fig. 1 is a plan View of the screen in completed form; I
.Fig. 2 is a section through the. screen plate before, it has been worked upon;
Figure 3 shows the slot formed in the screen plate;
Fig. 4.shows the formation of the final ridge containing the slot in the screen plate. Referringto' the drawings in detail it will be observed that in Fig. 1 I have provided a screen composed of a plurality of sections in which there are arranged in regular order a series of spaced, raised areas having relatively long, fine slots.
. l desi nates one section of the screen plate. a The method of forming such plates consists of first depressing a portion. of the metal of the plate in.such a way as to move a tongue thereof outwardly, such tongue being designated 2 and thereby shearing it along avertical face 3. The extent of the struck-up portion of the art 2 will determine the width of the resulting bend formed by an extrusion "'35 in like manner in a similar adjacent part designated 4:. I have found that it is impossible. to cut a slot which will be fine enough In a plate of this character to retain the granular material and, at the same time, permit 40 the fluid to flow therethrough. The result/of this operationis to form a very fine long narrow slot 5, any number of which, maybe arranged in spaced parallelrelatidnship in the struck-up portions 2 and 4 of the metal 46 of the section of the plate.
It is preferred to have these slots relatively narrow and relatively long so that the the first portion whereby the severed faces total area of the water introduced will be large and well distributed but the slot itself will be so narrow that the material can not 5 fall through it.
By having the struck-up portions I form an irregular bed for the material supported thereby which bed is constantl being stirred the struck-u portion to shear from the remainder of t e plate along one vertical face, and striking up a second portion. adjacent 7 0 remain adjacent to one another in a struck up area" to provide a very fine line of opening.
2. In a method of forming a screen plate, shaping a circular plate and forming in said circular plate a series of concentricall and, radially arranged elongated slots, sai slots being formed by striking up a portion ofv said plate and forming in said struck-up portion very fine elongated openings.
3. In a method of forming-a screen plate, shaping a circular-plate and forming in said circular plate a series of longitudinally and radially arranged elongated slots, said slots being formed by strikingup a portion of said plate causing the struck-up portion to shear from the'remainder of the plate alon one vertical face, and striking up asecon portion adjacent the first ortion whereby the severed faces remain ad acent to one another in the struck-up area to provide a very fine line of opening.
In testimony tvhereof, I affix my signature CHAS. P. EISENHAUER.
