rarer Application filed June 7, 1926. serial no. 114,153.
This invention relates to' an improved filter especially adapted for use in connection with the supply of hydrocarbon fed to the carburetor of a gas engine,
: its object' an improved organization of parts by means of which dirt particles and similar impurities not infrequently encountered in commercial supplies of gasoline may be automatically and efiicient y segregated there- ]0 from before the fluid reaches the carburetor where the presence of such particles would tend to clog its passages and otherwise impair its efficiency. While especially directed to such a use, it will be obvious that my construction is equally adaptable to use with fuel oil'for furnaces, and even for water,
and I desire the scope of my disclosure to be understood accordingly.
In the drawings:
Figure 1 is a plan view of my device taken from above,
Figure 2 is a partly sectional elevational view taken generally along the line 2-2 of Figure ,1, and looking in the direction of the arrows there shown.
Figure 3 is a sectional View taken along g 3-3 of Figure 2, and looking in the direction of the arrows there shown.
Figures 4 and 5 are detail plan views of the two forms of laminary stampings used for the built-up filtering element.
A' represents the body of the filter, which is provided with a bracket B having suitable holes for attachment to a support, such as the frame of an automobile; the filter body is provided with ports C and D, each having screw threadings for connection with the ends of the piping, between which the device is interposed. The body A is bored 40 to receive the filter-supporting head E, and a gasket F is interposed between the upper face of the body and the overengagmg flange E of the filter-supporting head, whose under face is provided with a deep annular groove G, into which opens a latthe line eral hole H. Diametrically opposed to the.
hole H there is located a depression J, which does not communicate directly with the annular oove G. p
The filter head E is provided with diametrically opposed notches K and K, while the body A is provided with a pin L, which one or the other of the notches may loclimgp ly engage, and so insure registration of the and has for .thus built up is hole H and depression J with the D and C respectively.
Centrally located on the filter head is a bore M Into wh ch the screw-threaded stem N engages. Thls stem is preferably hexagonal in cross section, or of any other non-circular cross section; a series of filtering elements V and W, stamped out from relatively tlun sheet metal, are ositioned along this stem 1n alternating re ation, being held in place thereon by the solid washer O and nut P. This is brought out in Figurest and 5, each washer havingfa central hexagonal opening and radial arms, the washers W being in addition provided with a continuous peripheral rim W uniting the outer ends of the arms; the rim is'omitted from washers V. It will be evident that, when these washers are alternatingly stacked, the arms oi: one series of washers will register with those of'the others, due to the directlonal eiiect of the hexing, the spaces between the arms forming a plurality of condu ts 1, parallel to the stem N. These conduits register at their upper ends with the roove Gr, and are closed at their lower ends by the washer 0. Due to the fact that alternate washers are rimless, there will thus be const tuted between successive or adjacently positioned washers, a plurality of peripherally narrow slits, the width or depth of wh1ch is determined by the thickness of the material of which the washers V are made, and, to a degree, by the tightness of their compression agamst one another as regulated by the nut P.
Spacedly engaging about the filter stack a sed ment cup S, whose flanged upper edge R is preferably, spaced irom the correspondingly shaped lower face of the filter body A by the annular gasket Q. The cup may be held in position under the filter body by any desired or appropriate means, that herein illustrated being a clamp or stirrup T, whose lower point ortip engages undera reinforcing ring R while its upper end, which over-reaches the top of the filter-supporting head E, is screwthreaded, for the. adjustable engagement therethrough of the nut Y, which can be screwed against the top surface of the head E to the degree necessary to insure the comressive assemblage of the sediment cup S and filter-supporting head E.
passages w While the fluid to be filtered may be passed through the structure thus assembled in either direction,. that is, may enter through the port C and emerge through the port D, or vice versa, Iipreferably indicate, by the arrows shown on the exterior of the shell in Figure 1, the direction which I prefer the flow to 0. This involves the entrance-of the fluid through the port C, whence it proceeds downwardly between the periphery of the filter stack and the wall of the sediment cup, and thence laterally through the numerous narrow and peripherally open slits between the several stamped-out washer pieces whlch form the filtering member. After passing inwardly through these narrow slits, to the exclusion of solid and impure particles of which it is desired to clear the fluid, and which latter fall to the bottom of the sediment cup, the fluid passes upward through the conduits I, annular groove G and lateral hole H. Thus the fluid passes onout through the outlet port D freed of the foreign particles which have been retained in the sediment cup S, which can be removed for cleaning as desired. There would be no objection, other than for obvious reasons of convenience in taking apart and cleaning of the parts, to the port D serving as the inlet port for the fluid while emerging through the port C. The flow -of the fluid relatively to the laminated filter stack would then be centrifugal rather than centripetal, and the intercepted 8 foreign particles would thus be caught in the conduits I, instead of the much more easily accessible and removable sediment cup S.
What I claim is:
1. A filtering element formed of a stack of thin washers having holes pierced there through toform a longitudinal channel substantially parallel to the axis of the stack when in registration with one another, and means to hold said washers against rotation to maintain said registration, some of said washers havin a portion of the periphery removed to a 0rd communication between the outside of said stack and the said longitudinal channel, said removed part being of the entire thickness of the washer.
2. A filtering element of generally cylindrical contour, consisting of a correlating element, and a plurality of washer members coaxially positioned thereby in closely assembled relation. certain portions of each washer element being apertured in positions of registry with one another to conjointly form longitudinal passages. and the peripheral portions of certain of the washers being also cutaway circumferentially opposite some of said passages, whereby, in conjunction with the periphery of the adjacent washers in the stack, there are constituted numerous radial channels of the thickness of the washers for the filtering passage of a fluid.
In testimony whereof, I sign this specifi cation.
