AMLOTT CLEANER SILENCER ASSEMBLY 2 Sheets-Sheet Filed NOV, 16, 1953 Unit Norman I.

3 Claims. (Cl. 18S-15) This invention relates to cleaner silencerassemblies for use in= cleaning air supplied to and silencing the noises emanating` from devices employing air induction means, and hasl particulark relation to cleaner silencer assemblies applicable for use with carburetors of internal combustion engines for automotive and other uses.
In providing cleaner silencer assemblies for use with engines, particularly V-type engines now being generally employed in automobiles and for other purposes it has become. difficult to devise an effective cleaner and silencer element that can be located' inf the limitedl space available. Wherever space is limited it is especially difficult to design anyy kind of a cleaner silencer structure that will operate efficiently' and that can be manufactured at a relatively low cost.
In' structures of this kind which heretofore have been designed both the cleaning and silencing characteristicsof the'- structureshave been affected. When a cleaner and silencer was made in such a way that the depth of the structure was reduced to a minimum it has been found that the velocity of the air leaving the cleaner has been so great that oil or dirtv or both oil and dirt which is not trapped and retained by the filter element is immediately conducted through the structure and into the engine or other device with which the structure may be employed. Also it has been' found that the lack of depth has impaired the effectiveness of the silencing chamber of any givenv volume, particularly when the structure has been constructed in such a way as to provide an eicient cleaner. The space required for the cleaner has interfered with the'A construction of a silencer in which the acoustical elements are proportioned to provide the sound attenuationresultsrequired.
It' is proposed toconstruct acleaner silencer assembly in which both the cleaner and the silencer structure will' berelativel'y wide and shallow. the cleaner and silencer elements in such away that theV shallow depth ofv one element is aligned with the shallow depth of the other and then to provide a large dome for the cleaningVv element which projects a substantial distance into the silencing element. The dome is then formedto'v provide a reduced but relatively wide and shallow outlet extending a substantial distance toward one wall ofthe silencer element. The silencer element then is provided with a relatively wide but shallow outlet extending from one side thereof and telescopically receiving the relatively widey and shallow outlet from` the cleaner dome. TheV silencer outlet is then: formed to provide a downwardly extending passage to which the inlet of an engine carburetor" or other air inductionI means may be connected. It is also proposed to prevent vibration of thek relatively large and at walls involved in the structure by connecting the-top wall. of the silencer to the bottom wallv of the cleaner, thereby preventing sounds from being created by the silencer and resulting from the sound waves that are trapped and attenuated therein.
In the drawing:
Figure l is aside elevational view of a cleaner silencer assembly embracing the principles of the invention. In Figure l' theu exterior walls of the structure are4 broken lt is proposed toy assemble States Patent Patented .lune 5, 1956 away in different areas to illustrate in cross section the internal structurev of the assembly.
Figure 2 is a cross section view of the cleaner silencer outlet taken substantially in thev plane of the line 2-2 on Figure 1 looking in the direction of the arrows thereon.
Figures 3 and 4 are views similar to- Figures l and 2 respectively and illustrating; another form which the invention may assume.
Referring particularly to Figures l and 3 the numeral 10 indicates generally a cleaner silencer assembly which may be` formed by assembling a cleaner element 11 and a silencer element 12.
While any suitable form of cleaner element may be employed, the cleaner element 11 is an oil bath* type of cleaner comprising a filter 13 formed` within a casing 14 having an annular inlet 16 in the lower wall thereof and an annular outlet 17 in the upper wall thereof. The: filter 1'3 and casing 14 may be of any suitable form. Spaced radially outwardly and downwardly from the cleaner element casing 14 is an inlet casing 18 which provides an annular. air inlet 19 aroundl the filter casing 14 and an oil sump 211 beneath the inlet 16. The oil level within thev casing 18 is indicatedat 22. Within the oil sump 21- is an oil control baie 23 of any suitable form.
The silencer element 1-2may be constructedy in any suitablev manner as by providing aresonating chamber 24 within a' casing 26 thereof. The casing 26 may be formed by providing an upper wall 27 and a lower wall 28, the two walls being flangedinwardly at the peripheral edges thereof to provide a continuous side wall indicated at 29. The flanged edges of the walls 27 and 23V may be turned outwardly at the adjacent ends thereof to provide a' bead 31 or other suitable means for securing the walls together.
The lower wall 28' may be formed to provide an upwardly projecting channel 32 in which a gasket 33 may be positioned. The cleaner unit 11 and silencer unit 12 may be secured removably together by a wing bolt 34 extending through the upper wall 27 of theA casing 26 and into a threaded opening, 36 formed in a securing member 38 which may' if desired be employed to hold the various elements of the cleaner 11 together and to compress theV upper beaded edge 39 of the casing 14 into` the gasket 33;
It is preferred in the assembly to construct both the' cleaner element 1'1, andthe silencer element 12' in relatively wide and shollow form, with the silencer element preferably beingl wider and overhanging the cleaner element. cleaner and silencer unit for the height of the structure. By securing the outer walls of the twovstructures together by employing means such as the wing bolt. 34, it will be` construct the lower wall 28 of the silencer element toprovide` at relatively large dome 41 that preferably extends intoy the resonating chamber 24 a considerable distance toward the upper wall 27 of the casing 26. The dome 24V also preferably is enlarged laterally in all directions towardthe. sidewalls 29 of the casing, to provide, a, settling chamber whereY relatively large particles` of dirt and oil that may escape from the filter element 13 may settle into the `filter elementwithou-t being carried intoi the air inductionmeans bythe high velocity blast of air which otherwise might be formed. beyond thel filter element 113'. In the present instance the domeA` or settling chamber 4,1 is: formed:y by depressing'the part of the lower wall' 28' which is directlyV above the filter element' 13, upwardly into" the resonati'ng chamber 24 asf is indicated atf42'. The anged Such construction will' provide a relatively large.
upper edge 43 of the wall 28 then may be connected by spot welding indicated at 46 to an inner casing 44 forming an upwardly and inwardly disposed extension of the end wall 28. The inner casing 44 may be formed by an upper wall 47 and a lower wall 48, the two being outwardly flanged and beaded as is indicated at 49. The inner casing 44 may be extended to one side of the dome 41 to provide a cleaner outlet indicated at 51. The outlet 51 may be formed in any suitable manner as by continuing the upper and lower walls of the inner casing 44 laterally to one side of the upper part of the dome 4l and toward the side wall 29 of the casing 26. lt is also preferred to construct the outlet 51 of substantially reduced cross sectional area compared to the dome 41 but in such manner as to provide a relatively wide and shallow passage such as is indicated in Figure 2. The air ow passage between the cleaner element 11 and the air induction means to which the silencer element may be Connected may be acoustically coupled to the resonating chamber 24 in any suitable manner. However, in the present instance the outlet end of the outlet 51 may be telescopically received and uniformly spaced within a larger but likewise relatively wide and shallow cleaner silencer outlet indicated at 52. The cleaner silencer outlet may be constructed integrally with the casing 26 or may be made of separate parts and received within the flanged opening 53 formed in the casing side wall 29 in directly opposed relation to the end of the cleaner outlet 51. The cleaner silencer outlet if constructed as a separate unit as shown may also be constructed by employing an upper wall 54 and a lower wall 56 having the edges thereof flanged inwardly and secured together by a bead indicated at 55. In order to attach the assembly to the air induction means of any device, it is proposed to provide a downwardly ilanged opening 57 in the lower wall 56 which may be secured to and aligned with the intake opening in the air induction means.
The resonating chamber 24 should be large enough in volume about the dome 41 to provide the capacitance required and the annular space 58 or inertance coupling between the cleaner outlet 51 and the cleaner silencer outlet 52 should be large enough and long enough to attenuate the sound waves emanating from the air induction means with which the assembly is employed.
In the structure disclosed by Figures 3 and 4 the principal difference between this and the structure disclosed by Figures l and 2 is in the construction of the upper wall 28 of the casing 26 which surrounds the dome 41. In Figures 3 and 4 the dome 41 is of a somewhat less expensive construction than is illustrated by Figures l and 2. In Figures 3 and 4 the dome 41 is formed by depressing the wall 28 upwardly and in such manner as to provide a wall section 61 extending normally to the flow of air within the cleaner silencer outlet 52. The wall section 61 is then anged as at 62 to receive a relatively wide and shallow tube such as that indicated at 63. The tube 63 extends telescopically within and in equally spaced relation to the end 64 of the cleaner outlet 52 which projects a substantial distance within the resonating chamber 24.
Otherwise the structure disclosed by Figures 3 and 4 is similar to that disclosed by Figures 1 and 2 and the same reference numerals are therefore employed to indicate corresponding structural elements in the two assemblies.
