March 9, 1965 R. R. HARROUN CARBURETOR AIRCLEANER RETAINER BAIL Filed Aug. 14 1961 INVENTOR. men mp R.HARROUN BLQ ATTORNEYS United States Patent 3,172,749 CARBURETOR AlRCLEANER RETAINER BAIL Richard R. Harroun, Orchard Lake, Mich., assignor t0 Holley Carburetor Company, Warren, Mich, a corporation of Michigan Filed Aug. 14, 1961, Ser. No. 131,155 1 Claim. (Cl. 55507) The invention relates to aircleaners and refers more specifically to apparatus for securing an aircleaner to a carburetor which apparatus is so constructed and is so installed on the carburetor as not to obstruct the air induction passage of the carburetor.
In the past, aircleaners have been provided with a mounting ring adapted to be sleeved over an aircleaner mounting lip provided on a carburetor air horn and have been held in assembly with the carburetor by means of a bolt extending through the aircleaner centrally thereof and secured to an aircleaner hold down bracket positioned over the air induction passage of the carburetor in obstructing relation thereto. This means of securing an aircleaner to a carburetor materially effects the operation of the engine with which the carburetor is associated in that a measurable engine power loss is effected by the interference of the aircleaner hold down bracket with the free passage of air into the carburetor air induction passage.
It is therefore one of the objects of the present invention to provide apparatus for securing an aircleaner to a carburetor which does not obstruct the air induction passage of the carburetor.
Another object is to provide apparatus for securing an aircleaner to a carburetor including a U-shaped aircleaner hold-down bail having an aircleaner mounting stud secured thereto centrally thereof and a separate aircleaner mounting lip member adapted to clamp the ends of the aircleaner hold-down bail to the carburetor air horn.
Another object is to provide apparatus for mounting an aircleaner on a carburetor as set forth above wherein the ends of the aircleaner hold-down bail extend radially outwardly and then axially downwardly of the carburetor air horn in assembly, the carburetor air horn is provided with axially extending recesses at opposite points around the circumference thereof for receiving the axially downwardly extending portions of the ends of the bail and the separate aircleaner mounting lip member is provided with similarly positioned, radially extending recesses for receiving the radially extending portions of the ends of the bail.
Another object is to provide apparatus for securing an aircleaner to a carburetor which is simple in construction, economical to manufacture and efficient in use.
The foregoing as well as other objects will become more apparent as this description proceeds, especially when considered in connection with the accompanying drawing illustrating a preferred embodiment of the invention, wherein:
FIGURE 1 is a partial section of an aircleaner mounted on a carburetor by aircleaner mounting apparatus constructed in accordance with the invention.
FIGURE 2 is an enlarged cross section of the carburetor, aircleaner and aircleaner mounting apparatus shown in FIGURE 1 taken on line 2-2 of FIGURE 1.
With particular reference to the figures of the drawing one embodiment of the present invention will now be disclosed.
As shown best in FIGURE 1, the aircleaner is mounted on the carburetor 12 by the aircleaner mounting apparatus 14. The aircleaner mounting apparatus 14 includes the aircleaner hold-down bail 16 and the aircleaner mounting stud 18. The aircleaner hold-down bail 16 is secured to the carburetor 12 by the separate aircleaner mounting lip member 20 in a position such that the air induction passage 22 of the carburetor 12 is not obstructed thereby.
More specifically, the carburetor 12 includes the carburetor air horn 24 having a venturi portion 26 which with the separate aircleaner mounting lip member 20 forms the carburetor air induction passage 22. The annular flange 30 is provided on air horn 24 for securing the separate aircleaner mounting lip member 20 to the carburetor air horn 24. Axially extending recesses 34 are provided in the carburetor air horn 24 as shown in FIG- URE 1 to receive the ends 36 of bail 16.
The separate aircleaner mounting lip member 20 also includes an annular flange 28 by which it is secured to the annular flange 30 provided on the carburetor 12 by convenient means such as screws 32. Radially extending recesses 38 as best shown in FIGURE 1 are provided in the separate aircleaner mounting lip 20 for receiving the radially extending portion 40 of the ends of the aircleaner hold-down bail 16.
The aircleaner hold-down bail 16 of the aircleaner mounting apparatus 14 is a U-shaped resilient member which may be constructed of spring steel for example. Bail 16 is provided with the ofiset end portions 36 mentioned above which are clamped between the carburetor air horn 24 and the aircleaner mounting lip member 20 in assembly as shown in FIGURE 1.
The aircleaner mounting stud 18 is provided with a head 41 having an opening 42 therethrough. The bail 16 is passed through the opening 42 in head 41 to secure the stud 18 centrally of the bail 16 as shown in FIG- URE 1.
Aircleaner 10 includes upper and lower exterior housing members 44 and 46, respectively. The lower housing member 46 includes an aircleaner mounting ring 48 adapted to be sleeved over the separate air horn mounting lip member 20 in assembly, as shown best in FIGURE 1. Aircleaner 10 further includes a filter member 50 including the filter material 52 secured between the upper and lower annular plates 54 and 56 and the screen 58 in conjunction with a radially outer annular screen (not shown).
In securing the aircleaner 10 to the carburetor 12 the mounting apparatus 14 is first positioned on the carburetor 12 with the offset ends 36 of the aircleaner hold-down bail 16 positioned within the recesses 34. The separate aircleaner mounting lip member 20 is then positioned over the bail 16 with the bail 16 fitting within the axial grooves 60 therein, as best shown in FIGURE 2, and with the radially extending portions 40 of the bail 16 within the recesses 38. The aircleaner mounting lip member 20 is then secured to the carburetor 12 by means of the screws 32 and the flanges 28, 30. A sealing gasket 62 is placed on the lip 28, as shown best in FIGURE 1, and the aircleaner 10 is sleeved over the aircleaner mounting lip member 20 so that the stud 18 extends through the opening 64 in the upper housing member 44 of the aircleaner 10. The washer 65 is placed over the stud 18 and the nut 66 is then threaded on the stud 18.
Thus it will be seen that in accordance with the invention there is provided mounting apparatus for securing an aircleaner to a carburetor which is simple in construction, economical to manufacture and efficient in operation. Further, the mounting apparatus for the aircleaner, in accordance with the invention, is so constructed as not to obstruct air being drawn into the carburetor induction passage 22.
The drawing and the foregoing specification constitute a description of the improved aircleaner mounting apparatus in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claim.
