Abstract
Abstract A method of securing top and bottom members to intermediate plate structures by providing spaced apertures in the plate, positioning members on either side of the plate at least one of which is provided with mating portions such that the mating portions are within the spaced apertures in engaging relationship with the other member and providing an adhesive on at least those portions of the members in mating engagement to thereby form a unitary structure of somewhat rigid stability. The products formed by the disclosed methods will find application for use in conjunction with carburetor assemblies wherein the plate structure is metal so as to act, for example, as a heat dissipator between the carburetor manifold and carburetor throttle body. The method may be used in many other types of assemblies wherein the assembly of three parts is difficult to accomplish at high speed with complete reliability.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
24 words
The method in accordance with claim 1 wherein a plurality of adhesive spots corresponding to said apertures are applied on said flexible, deformable material.
Claim 2
Dependent Claim
53 words
The method in accordance with claim 1 wherein an adhesive layer is formed on the entire interior face of said fLexible, deformable material member and a masking member is positioned between said member and said plate to prevent adhesion with said metal plate but allows for adhesion between outer members within said apertures.
Claim 3
Independent Claim
155 words
The method of securing a plate between two adjacent deformable members to thereby form a sandwich comprising: cutting said plate to the desired configuration and providing a plurality of spaced apertures therethrough; cutting each of said adjacent members to the desired configuration with each having at least one protuberance or tab adapted to engage in mating relationship the protuberance or tab of the other member within at least one of said spaced apertures, said protuberances or tabs being of congruent configuration to said aperture, providing an adhesive between the protuberances or tabs of each of said members adapted to meet in mating relationship within at least one of said apertures of said plate, positioning said members in aligned relationship on each side of said plate, pressure contacting and deforming said protuberances or tabs through at least one of said spaced apertures, allowing said adhesive to set; and recovering said plate and members in sandwich form.
Claim 4
Dependent Claim
48 words
The method in accordance with claim 4, wherein the affinity for adhesion between mating surfaces of said members is greater than that between the surface of each of said members, and said plate and the number of tabs and apertures are sufficient to provide a quasi-unitary sandwich structure.
Claim 5
Dependent Claim
37 words
The method in accordance with claim 5 wherein said plate is planar and of metal of high thermal conductivity and said adjacent members are sheet-like and at least one of said members provides a heat insulative layer.
Claim 6
Dependent Claim
30 words
The method in accordance with claim 6 wherein the other of said members is of gasket character adapted to effect a seal in the assemblage wherein said sandwich is used.
Claim 7
Dependent Claim
31 words
The method in accordance with claim 7 which additionally includes the step of chamfering the edge of said apertures so as to facilitate said mating engagement of said protuberances or tabs.
Claim 8
Dependent Claim
27 words
The method in accordance with claim 8 wherein said adhesive is a curable polymer and the sandwich in its assembled form is subjected to a curing step.
Claim 9
Dependent Claim
57 words
The method in accordance with claim 9 wherein an adhesive layer is provided, on the interior surface of at least one of said adjacent members and a masking member is interposed between said plate and said interior surface to thereby mask said plate from said adhesive layer and only provide said adhesive for bonding within said apertures.
Claim 10
Dependent Claim
24 words
The method in accordance with claim 10 wherein said masking member is of gasket character and said apertures are slightly larger than said tabs.
