FLOATING SCREEN Filed March 18, 1947 IN VENTOR /4 ,q Leroy E /1//ne ZQAL'HM Patented May 23, 1950 UNITED STATES PATENT OFFICE FLOATING SCREEN Leroy F. Kline, Wayne, Mich., assignor to Industrial Wire Cloth Products Company, Wayne, Mich, a. corporation of Michigan Application March 18, 1947, Serial No. 735,433
1 Claim. 1
The present invention relates to floating oil screens and has among its objects to provide a screen that is more efficient in operation and less expensive to construct than the forms heretofore known and used.
Another object is to simplify the construction and installations of such screens.
Other objects and advantages will be apparent to those skilled in the art upon reference to the following description and the accompanying drawings in which:
Figure l is a plan view of a screen embodying the present invention.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a view in elevation as from the bottom of Figure 1.
As indicated in the drawing, the screen comprises an outer bell member ID provided with a shoulder IUA within which is fixed a shell 1GB so as to provide a float chamber surrounded by a channel l2. Fixed to the edge of bell It as by crimping as at i3 is a guard or cover H1 dished downwardly and provided with openings MA and also with a central circular boss or dimple MB. The cover it is spaced from the shell 10B which is provided with ribs IUC extending radially of the shell and outwardly toward the cover I l.
Fixed within the space between the cover I4 and shell |B is a screening element 15 of flexible mesh material. This element l5 will be in the form of a disc having its edge secured in the crimp l3 and having at its center an opening in which is fixed a grommet l5 of such size as to form a valve with the boss MB. The element I5 is pressed downwardly by the ribs EC in shell IUB so that the grommet |6 coacts with boss MB and closes the central opening in the screen. The ribs IOC, however, do not extend to the center of shell |8B but stop short thereof a sufficient distance to permit the central portion of the element It to lift from boss I4B if and when it becomes plugged.
Fixed to the outside of bell l0 and opening thereinto is a tube 2| communicating With the annular space l2. The tube 2| will be bent as shown so that its inbent end portion will extend in a direction perpendicular to a radius of the bell and will be supported by a plate 29.
This plate 20 will be formed so that a portion 200 will conform to the outside of bell l0 while one end will be bent outwardly and at right angles to the inbent portion of tube 2| which will pass through and be fixed to the plate. The
plate, tube and bell will preferably be brazed or otherwise permanently fixed together. Plate 20 will be provided with suitable ears 2013 serving as stops for the screen assembly and the tube 2| will be upset to provide a circumferential rib or flange 2|A adapted to coact with a retaining nut (not shown), allowing the screen assembly to swing about the axis of the inbent portion of the tube.
In operation, the device will be supported by the free end of tube 2| in the inlet of the oil circulating system of an engine with the screen assembly adapted to float in or on the body of oil in the crankcase, with the inlets |4A submerged in the oil. Since the oil enters by suction, it will normally pass through screening element i5 into the annular space I2 and out through tube 2|. When, however, the element |5 becomes plugged with dirt and such, continued suction will open the valve formed by grommet I6 and boss MB and allow oil flow without screening.
I claim:
A floating oil screen for use in the oil sump of an internal combustion engine, said screen comprising a bell portion enclosing a float chamber, the side wall of said chamber being spaced from said bell to provide an annular chamber, an oil screening element covering the open end of said bell and annular chamber, a perforated guard plate arranged over said screening element and provided with an upwardly extending boss, said screening element being provided with an opening opposite to and adapted to be normally closed by said boss and outlet means leading from said annular chamber.
