Abstract
Interchangeable venturi sleeves are removably positioned in open-ended bores of a carburetor center section. Each of the sleeves is colored a particular color corresponding to the physical parameters of the sleeve, for example, inner diameter and shape. Similarly, base plates and metering blocks of different capacities are provided such that the operating parameters of the carburetor can be changed. Like the venturi sleeves, the base plates and metering blocks are color-coded to indicate their physical parameters. With this color-coding, the observer can quickly and easily determine the physical characteristics of the carburetor.
Claims16
A carburetor for an internal combustion engine, comprising:
- a carburetor center section defining a plurality of open-ended bores of substantially the same size and shape extending therethrough;
- a plurality of sets of venturi sleeves for removably positioning in each of said bores, all of said sleeves of all of said sets having an external surface sized and shaped to match the size and shape of said bores of said center section and an internal venturi throat having an annular wall constriction provided thereon for generating a zone of low pressure at the constriction in response to a flow of air moving through said throat;
- each sleeve of each set of sleeves having identically sized and shaped venturi throats, and the sleeves of different sets of sleeves having differently sized and shaped venturi throats, and the identically sized and shaped sleeves of each set of sleeves bearing the same color, and the sleeves of different sets of sleeves bearing different colors, each of said colors corresponding to the sizes and shapes of the venturi throats of said sleeves, wherein the color of each venturi sleeve identifies the size and shape of the venturi sleeve;
- and
- means for holding said venturi sleeves in said bores;
- whereby when sleeves of the same color are positioned in the bores of a carburetor, all of the sleeves will have identically sized and shaped venturi throats.

A carburetor for an internal combustion engine, comprising:
- a carburetor center section defining a plurality of open-ended bores extending therethrough;
- a venturi sleeve removably positioned in each of said bores, each said sleeve having an external surface sized and shaped to match the size and shape of said bores and an internal venturi throat having an annular wall constriction provided thereon for generating a zone of low pressure at the constriction in response to a flow of air moving through said throat, wherein each said venturi sleeve bears a color for visually identifying the sizes and shapes of the venturi throats with sleeves of the same size and shape bearing the same color;
- a baseplate removably attached to said center section and having a plurality of openings extending therethrough, each opening being dimensioned to match the size and shape of a lower end of said venturi throats of said venturi sleeves, said baseplate bearing a color which corresponds to the color of said sleeves for visually identifying the dimensions of said openings provided in said baseplate;
- and
- a pair of fuel metering blocks removably attached to said center section and bearing a color which identifies the type of fuel to flow through the metering clock;
- so that when venturi sleeves, a baseplate and a pair of metering blocks of corresponding colors are assembled on a common center section, their sizes, shapes and capacities will match each other.

A carburetor for an internal combustion engine, comprising:
- a carburetor center section defining a plurality of open-ended and substantially identically sized and shaped bores extending therethrough;
- a venturi sleeve removably positioned in each of said bores, each venturi sleeve having an exterior surface being sized and shaped to match the size and shape of said carburetor bores and an interior surface defining an internal open-ended venturi throat for permitting the flow of air therethrough, said venturi throat having an annular wall constriction for generating a zone of low pressure at said wall constriction in response to air moving through said throat;
- said venturi sleeves being selected from a supply of venturi sleeves consisting of:
- groups of venturi sleeves, with said venturi sleeves of each group having substantially identically sized and shaped venturi throats, and the size and shape of said venturi throats of each group being different than the sizes and shapes of said venturi throats of other groups of venturi sleeves, and all of said venturi sleeves of each group of venturi sleeves being of the same color, and said venturi sleeves of each group being of different colors than said venturi sleeves of other groups, wherein visual inspection of said venturi sleeves in said bores of said carburetor center section reveals the color of said venturi sleeves and therefore indicates the size and shape of said venturi throats of the venturi sleeves in the carburetor center section.
1 more element
A method for assembling carburetor components with corresponding sizes and shapes, said method comprising the steps of:
- providing a carburetor center section defining a plurality of open-ended bores extending therethrough;
- inserting a plurality of venturi sleeves in the bores, each sleeve having an internal venturi throat for passing air therethrough, wherein the size and shape of the venturi throats of the venturi sleeves are indicated by the color of the sleeves;
- mounting a baseplate to the base of the center section and having a plurality of openings therein dimensioned to match the dimensions of a lower end of the venturi throats, wherein the size of the openings in the baseplate is indicated by the color of the baseplate and corresponds to the color of the sleeves;
- and
- providing a chart which conveys the correlation between the color of a component and the physical parameters of the component;
- whereby upon inspecting the assembled carburetor and referencing the chart, one can determine the physical parameters of the colored components.
