STRAINER BAFFLE Fle March 4, 1930 INVENTOR STEPHEN VORECH ATTORNEY Patented Qct. 27, 1931 UNITED STATES PATENT oFFIcE STEPHEN Vennen, OEWILMEEDING, PENNSYLVANIA, AssIGNoEzmo THE WESTING- HOUSE Ain BRAKE; COMPANY, or WILMERDING, PENNSYLVANIA, A conromurroN\ i j or PENNSYLVANIA i STRAINER BAPFLE "Application meaMawhA, 1930. serial No. 433,057.y
This invention relates to air purifiersand more particularlyto that type for use in vacuum brake equipment.y
The principal object of my invention is to provide a cover or baffle device for an air strainer which will prevent dirt and moisture from being deposited directly uponthe air inlet portion of the strainer yand which, at the same time, will permit an airstream to flow freely therethrough to the strainer.'
A further object of my invention is to provide a cover or baiiie device for an air strainer which will separate large particles of matter foreign to air from the air stream flowing through said cover to the strainer.
In the accompanying drawings; Fig. 1 is a longitudinal sectional View taken horizontally through a portion of an automotive vacu- A um of a lever 4, pivotally anchored to the' um brake equipment embodying my invention; Fig. 2 is an enlarged detail plan view of one portion of the cover device; Fig.3 is a cross sectional view of the same taken on the line 3-3 of Fig. 2; Fig. 4 is an enlarged detail plan view of another portion of the cover device; and Fig.` 5 is a cross sectional view of the same taken on the line 5-5 of Fig. 4.
In Fig. 1 of the drawings I have shown my invention applied to an automotive vacuum brake equipment of the usual well known type, only so much of the equipment being illustrated in the drawings as is deemed necessary for a clear understanding of the invention. y
The portion of.. the automotive vacuum brake equipment whichr is illustrated comprises a casing 1 having a piston 2 mounted therein, which piston is operatively connected to the usual push rod 3 through the medicasing, and a chain, Said lever, chain and one end of the push rod being contained in a chamber 6 at one side of the piston 2, which chamber is constantly 'connected to the atmosphere through a passage 7 formed in the casing 1.
Leading from the chamber 8 at the other side of the piston 2 is a pipe 9 through whichy air from the chamber may be expelled in the usual manner to create a ypartial vacuum at this side of the piston.
For the purpose of cleansing the air flowing from the atmosphere to the chamber 6, there is interposedin lthe passage 7, an air strainer of theusual type having spaced inner andl outer perforatedplates 10 and 11`respectively, between which there is a' suitable air cleaningmedium, such as pulled curled khair or the like. The outer edge portion of the inner strainer plate 11 engages an inwardlydir'ecte'd annular flange 12 formedv integral with the casing 1. Y I
`For the purpose of'preventing moisture and other matter foreign to air yfrom `being deposited directly into, the strainer vand to assist in cleansing the air stream flowing into the chamber 6,'I provide a cover kor baffle device 13 which rests on the outer plate 10 of the strainer, saidfdevice comprising a plate 14 to which' issecured a cap member 15. i
The plate 14 has a flat annular' outer portion 16r having a plurality of rectangular openings 17 formed therein. /This plate has a'central opening 18which is defined by `an annular baiiie wall' or i'ange119 whichl eX- tends outwardly some distance beyond the plane of the fiat portion 16.v The cap member 15 has a top or cover portion-20 and an inwardly directed annular wall 21, said cover portion and'wallbeing preferablyinteg'ral. The Wall 21 is provided withr spaced ylugs 22 which, in assembling the baffle device, are inserted in the openings 17 in `the plate 14..' The outer ends of these lugs project through the plate 14, and to secure the cap 415 and plate y14 together, the projecting ends of ythelugs are bent into engagement with one side of the plate 14. When the lugs are thus bent, the edge portions of the' wall 21y engages the other side of the plate 14.y f
The wall21 is provided withnotches 23 which are alternately spaced with the lugs 22 and which. together with the plate 14, define openings through which yan air stream is adapted to iow to a clear air; space 24'which n is defined by thefbaieflange'lf) of the plate -14 and the wallf21 ofthe cap member 15. Y There is ralso a clearair space between the Ainnersurface of the cover portion 20 of the cap member 15 and the outer edge ofthe baile` f liange 19 so that air from the airspace 24 is lfree to flow through the opening 18 to the will not flow directly-through the s ace between the top of the flange 19 and t e cover portion 20, but will first strike against the flange 19 and then flow through this space and. opening 18 to the strainers.
lVhen the cover or baffle device 13 is mounted in its proper position in the casing, as shown in Fig. 1, the bent-over lugs 22 rest against the outer surface of the perforated strainer plate 10 and thus space the fiat annular portion 16 of the plate 14 away from the outer surface of the plate 10, so that this portion 16 Oilers substantially no obstruction to they flow of the air stream to the strainer.
The device 13 is removably held in its proper position in the casing and against the strainer by asnap ring 25 which engages the flat portion 16 of the plate 14 and also engages the casing within a circular groove.
It will be seen that the cover or bale device 13 is well adapted to prevent matter foreign to air frombeing deposited directly on the inlet endV of the strainer and to per- Y mit the4 free flow of air therethrough to the strainer. y A
Air flowing from the atmosphere to the chamber 6 passes through the notches 23 in the wall 21 of the cap member 15, clear air space 24, over the outer edge of the bale directly deposited into the strainer.
It will also he seen that some of the moisture and other foreign matter carried into the device 18 by an air stream, flowing therethrough will mpinge on the outer surface i of the baffle flange 19 andl condense thereon or be otherwise separated from the stream, and by the force of gravity, the matter septhe passage of air therethrough, said Walls and cover portion delining a tortuous passageway through which an air stream flows from the atmosphere to the air strainer.
In testimony whereof I have hereunto set mfy hand, this 28th day of February, 1930.
STEPHEN VORECH.
arated from the stream will' drop out ofthe 'v l device, thus rendering the device self cleaning.
By'the usey of theV snap ring`25 the removal and replacement of the device 13l is rendered very easy.
l/Vhile one illustrative embodiment of the invention has been described in detail, it is not my intention to limit its scope to that embodiment or otherwise than by the" terms of the appended claims.
Having now described my invention, what I claim as new and desire to secure by Letters Patent, is: e
1. A cover for an air strainer comprising arplurality of plates forming a passageway through which an air stream flows to said strainer, and lugs on one of said plates extending through and bent into engagement
