'7 Claims. 1

The present invention relates to a bracket for securing an air cleaner to a carburetor for an internal combustion engine.

An object of the present invention is to provide a bracket for securing an air cleaner to a carburetor, which permits the cleaner to be readily assembled in place on the carburetor and easily removed therefrom.

Another object of the invention is to provide a bracket for mounting an air cleaner on a carburetor, which can be easily and securely attached to the carburetor air horn before the cleaner is assembled in place.

A further object is to provide an air cleaner bracket for a carburetor which permits an air cleaner having an annular portion enclosing the upper end of the carburetor air horn to be readily assembled and secured in place on the air horn.

Additional objects and advantages of my invention will become apparent from the following description and accompanying drawings, wherein:

Figure 1 is an elevation of a carburetor and air cleaner showing a portion of the carburetor air horn and air cleaner broken away to reveal the construction of the means for securing the cleaner to the air horn; and

Figure 2 is a top plan view of the carburetor showing the bracket secured in place at the air intake end of the air horn.

For the purpose of the present description, the carburetor shown in the drawings may be considered as a conventional downdraft, float type carburetor consisting of an air horn It, a choke valve [2, a main body [4 including a float chamber l6, and a throttle body 18 adapted to be mounted on an intake manifold 20 of an in- (ternal combustion engine (not shown). The carburetor contains the usual main discharge jet, idling system, and accelerating pump and may include an automatic choke and fast idle cam, said cam being shown at numeral 22 mounted adjacent the throttle lever 24 and connected to the choke valve by a rod 26. The air cleaner may also be considered as a conventional unit and as illustrated includes a portion extending downwardly over the upper end of the air horn completely enclosing said air horn end.

The bracket 34 for securing the air cleaner to the carburetor air horn is an inverted U-shaped member 36 extending diametrically across the entrance to the induction passage of the air horn. The two arms 31 of the member are seated in vertical slots 38 disposed in thick sections 40 in opposite side walls of the air horn and are retained therein by pins 42 inserted in horizontal holes 14 extending longitudinally through thick sections 40 and through a hole 46 in each arm of the U-shaped member. These pins may be threaded at one end to prevent them from becoming accidentally dislodged, although the downwardly extending portion of the air cleaner may be sufficiently close to the side walls of the air horn to prevent the pins from becoming displaced during service. A sleeve or collar 48 is secured to the central section of the U-shaped member and rigidly supports a bolt 50 which extends upwardly through the air cleaner and in conjunction with a winged nut 52 holds the air cleaner in place on the carburetor. A flange around the air outlet of the air cleaner slips over the upper end of the air horn walls and seats on annular shoulder 62 and is held firmly in place during service by bracket 34.

In assembling the bracket and an air cleaner having a portion extending downwardly over the air horn of the carburetor, the arms of the bracket are placed in slots 38, and pins 42 are inserted in holes 44 and 46. The air cleaner is placed on the carburetor with flange 60 seated on shoulder 62 and then nut 52 is tightened on bolt 50, securing the cleaner in place for service.

Modification may be made in the bracket structure without departing from the scope of the invention. For example, instead of securing the bolt rigidly to sleeve 48, the sleeve may be threaded and the bolt inverted to extend downwardly through the air cleaner into said sleeve. Further, member 36, instead of being U-shaped, may be a straight bar provided with a hole at each end for receiving pins 42, and three or more arms 3! may be used in place of the two shown.

I claim:

1. In an assembly of an air cleaner and a carburetor having an induction passage: opposed slots in the internal wall of said passage extending parallel therewith, a member extending across said passage and having its ends inserted in said slots, a pin extending through each slot disposed in said wall and engaging an end of said member, and a means adapted to be conneoted to said member for securing said cleaner to said carburetor.

2. In an assembly of an air cleaner and a carburetor having an air horn with an air inlet passage: diametrically opposed slots in the internal wall or" said passage extending longitudinally of said passage, a U-shaped member extending across said passage and having its ends inserted in said slots, a pin extending through each slot disposed in said wall and engaging an end of said member, and a threaded member adapted to be secured to said U-shaped member for securing said cleaner to said air horn.

3. A structure for securing an air cleaner to the air inlet passage of a carburetor, comprising a plurality of means forming a pair of opposed slots in the internal side walls of said passage, at least one means on each side having a hole therein extending to the outside surface of said wall and intersecting said slots, a member extending across said passage, the ends of said member having openings therethrough and being adapted to seat in said slots, a pin in each hole inserted in the opening of said ends, and a means adapted to be connected to said member for securing said cleaner to said carburetor.

4. A structure for securing an air cleaner to the air inlet passage of a carburetor air horn, comprising a pair of diametrically opposed slots in the internal side walls of said passage, a U- shaped member extending across said passage, the arms of said member having openings therein and being adapted to seat in said slots, holes in said side walls intersecting said slots and extending to the outside surface of said side walls, a pin in each hole inserted in the opening of said arms, and a threaded member adapted to be secured to said member for securing said cleaner to said air horn.

5. A structure for securing an air cleaner to the air inlet pasage of a carburetor, comprising a pair of diametrically opposed slots in the internal side walls of said passage, a U-shaped member extending across said passage, the arms of said member having openings therein and being adapted to seat in said slots, holes in said side walls intersecting said slots and extending to the outside surface of said side walls, a pin in each 4. hole inserted in the opening of said arms, a rod secured to said member extending in the direction opposite to said arms and being adapted to extend through said air cleaner, and a means on said rod for securing said cleaner to said carburetor.

6. In the combination of a carburetor having walls forming an induction passage and an air cleaner bracket adapted to extend across said passage: a pair of opposed slots in the internal side walls of said passage for receiving the ends of said bracket, a hole in said side walls intersecting each slot and extending to the outside surface of the said side walls, and a pin in each hole adapted to engage an end of said bracket.

7. In the combination of a carburetor having walls forming an induction passage and an air cleaner bracket adapted to extend diametrically across said passage: a pair of diametrically opposed slots disposed in the internal side walls of said passage and extending longitudinally thereof for receiving the ends of said bracket, a bore in said side walls intersecting-each slot "and extending to the outside surface of said side walls, and a pin in each bore adapted to engage an end of said bracket and hold said bracket in operative position.
