Divided and this application December 2, 1954, Serial No. 472,558
4 Claims. (Cl. 29-1635) cation in conjunction with the accompanying drawings,
wherein: I
Fig. 1 illustrates a filter element made in accordance with the principles of my invention, with the elements adjacent the top end thereof exploded outwardly to illustrate their method of assembly.
Fig. 2 illustrates a piece of stock material prior to its being formed into a tube.
Fig. 3 shows one of the end rings prior to its mounting on the tube.
Fig. 4 illustrates the manner in which the end rings are fastened to the tube.
In making a filter element in accordance with the principles of my invention, a rectangular piece of sheet metal is first pierced to form a plurality of apertures 11 in the manner illustrated in Fig. 1. The piece of sheet metal 10 is then rolled into the form of a tube 12 and a ring 13, L-shaped in cross section as seen in Figs. 3 and 4, is placed over the end of the tube. A swaging die 14 is then used to swage the inwardly projecting flange 15 of the ring 13 into contact with the inner surface of the tube 12 and thus crimp the reinforcing ring 13 thereon. A second ring 16 is mounted on the opposite'end of the tube 12 in the same manner. It will be appreciated that the width of the stock sheet 10 may be greater than the length of the tube desired and the tube cut into proper lengths after the rolling step.
After the central tube 12 has been fitted at each end with the reinforcing rings 13 and 16, the filtering media 17 is mounted on the tube in the manner indicated by the dot-dash lines in Fig. 1. 18 of the filtering media initially extends beyond the end of the tube 12. A reinforcing nipple 19, having a depending cylindrical skirt portion 20 of slightly larger diameter than the swaging die 14, is pressed into the end of the tube reinforcing ring 13. An end plate 21 is mounted on said nipple 19 and rests against the underside of an outwardly projecting flange 22 thereon. The end plate 21 presses tightly against and compresses the end of the filteringmedia and insures against leakage around the end of the filtering media. A positioning washer 23, having a central aperture 24, is fastened to the nipple 19 and is adapted to properly position the filter element with respect to an upstanding central tube (not shown) within a filter housing. A similar nipple 25, having an end plate 26 and positioning washer 27, is pressed into the opposite end of the tube 12.
It is to be understood that the invention as disclosed It will be noted that the end ice v 1 2 above is equally .applicable in making filters of the socalled sock type by merely omitting the end plates 21 and 26.
While I have shown and described the preferred form of and the preferred method of making my invention, it is to be understood that various changes may be made therein without departing from the spirit of the invention as defined in the appended claims.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. The method of constructing a filter element comprising stamping a plurality of openings through a rectangular piece of sheet metal, forming said rectangular piece into a tube, placing a circular rim of L-shaped cross section on each end of said tube so that the longitudinal flange thereof embraces the outer surface of said tube to prevent unrolling of said tube, swaging the radial flange of said rims into parallelism with said longitudinal flange and adjacent the inner surface of said tube, and forcing a tubular nipple in each of said reinforcing rims, said nipples being slightly larger in outside diameter than the inside diameter of said reinforcing rims to insure a tight press fit.
2. The method of constructing filter elements comprising stamping a plurality of openings through a rectangular piece of sheet metal, forming said rectangular piece into a tube, cutting off sections of said tube of the proper length, placing a circular rim of L-shaped cross section on each end of each of said tubing sections so that the longitudinal flanges thereof embrace the outer surface of said tubing section to prevent unrolling of said tubing section, swaging the radial flanges of said rims into parallelism with said longitudinal flanges and adjacent the inner surfaces of said tubing sections, and forcing a tubular nipple in each of said reinforcing rims, said nipples being slightly larger in outside diameter than the inside diameter of said reinforcing rims to insure a tight press fit.
3. The method of constructing filter elements comprising stamping a plurality of openings through a rectangular piece of sheet metal,-forming said rectangular piece into a tube, cutting off sections of said tube of the proper length, placing a circular rim of L-shaped cross section on each end of each of said tubing sections so that the longitudinal flanges thereof embrace the outer surfaces of said tubing sections to prevent unrolling of said tubing sections, swaging the radial flanges of said rims into parallelism with said longitudinal flanges and adjacent the inner surfaces of said tubing sections, mounting a pair of end plates on a pair of tubular nipples, and forcing said tubular nipples one in each of said reinforcing rims, said nipples being slightly larger in outside diameter than the inside diameter of said reinforcing rims to insure a tight press fit.
4. The method of constructing filter elements comprising stamping a plurality of openings through a rectangular piece of sheet metal, forming said rectangular piece into a tube, cutting off sections of said tube of the proper length, placing a circular rim of L-shaped cross section on each of the ends of each of said tubing sections so that the longitudinal flanges thereof embrace the outer surface of said tubing sections toiprevent unrolling of said tubing sections, swaging the radial flanges of said rims into parallelism with said longitudinal flanges and adjacent the inner surfaces of said tubing sections, mounting a filtering media on each of said sections of tubing with the ends of said media extending beyond the ends of said tubing section, mounting a pair of end plates on a pair of tubular nipples, and forcing said tubular nipples one in each of said reinforcing rims, said nipples being slightly larger in outside diameter than the inside diameter of 2,830,369 3 4 I said reiqfotcing rims 1o insuxea tight press fit, said end 2,031,936 Cuno 'Feb. 25, 1936 plates compressing the ends of said filtering 1 61 Z12ZJZ MQ LQEFQ Deg. 23, 1941 2,460,296 Kinney References Cited in the file of this patent 2,543,481 Wicks et al.
