Abstract
Abstract A flexible header mounting for an engine mounted fuel filter includes structure for dependingly engaging a fuel filter and its associated plumbing and a planar base member by means of which the header is mounted to the engine supporting structure. Flexible engagement of the base member to the engine is accomplished by means of bolts, each of which has a compression spring mounted thereon over the shaft thereof, between the base member and the bolt head. The free threaded end of the bolt extends through a bore drilled into the base member and engages within a threaded bore in the engine housing. The distance between a center point of the bolt and a forward edge of the base plate is as large as possible while the distance between the center point of the bolt and the rear edge is as small as possible, creating a joint wherein the header may pivot rearwardly upon impact but will be unable to pivot forwardly under severe deceleration.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
69 words
In combination with an engine having a supporting structure, a flexible mount header for a fuel filter comprising header means for engaging a fuel filter, said header means having a planar base member disposed in engagement with said engine support structure, and spring biassed means for maintaining said base member and said support structure in engagement while permitting movement of said header upon a predetermined impact force acting thereon.
Claim 2
Dependent Claim
69 words
In combination with an engine having a supporting structure, a flexible mount header for a fuel filter comprising header means for engaging a fuel filter, said header means having a planar base member disposed in engagement with said engine support structure, and spring biassed means for maintaining said base member and said support structure in engagement while permitting movement of said header upon a predetermined impact force acting thereon.
Claim 3
Dependent Claim
19 words
The header of claim 1 wherein said base member has a forward edge, a rear edge and lateral ends.
Claim 4
Dependent Claim
23 words
The header of claim 1 wherein said base member has bores drilled therein which are positioned toward the lateral ends and rear edge.
Claim 5
Dependent Claim
42 words
The header of claim 3 wherein said compression type mount comprises a bolt having a washer engaged against a head thereof and said spring biased means is a compression spring coiled thereover between said washer and a free end of said bolt.
Claim 6
Dependent Claim
35 words
The header of claim 4 wherein the free end of said bolt passes through said base, compressing the spring between said base member and said washer when engaged to the surface underlying the base member.
Claim 7
Dependent Claim
42 words
The header of claim 5 wherein the distance between a center point of said bolt and the rear edge of the base member is substantially less than half the distance between the rear edge and a front edge of said base member.
Claim 8
Dependent Claim
41 words
The header of claim 6 wherein the distance between a center point of said bolt and the forward edge of said base member is substantially larger than the distance between said center point a said rear edge of said base member.
Claim 9
Dependent Claim
86 words
In combination with an engine, a flexible mount fuel filter header including means for engaging a fuel filter and a planar base member which is engaged to an underlying engine surface at least as large as said planar base member by at least one bolt, the bolt having mounted thereon a compression spring between said base member and a head of the bolt, the bolt being positioned substantially closer to a rear edge of the base member than to a front edge of said base member.
Claim 10
Dependent Claim
86 words
In combination with an engine, a flexible mount fuel filter header including means for engaging a fuel filter and a planar base member which is engaged to an underlying engine surface at least as large as said planar base member by at least one bolt, the bolt having mounted thereon a compression spring between said base member and a head of the bolt, the bolt being positioned substantially closer to a rear edge of the base member than to a front edge of said base member.
Claim 11
Dependent Claim
10 words
The header of claim 8 engaging a plurality of bolts.
Claim 12
Dependent Claim
8 words
The header of claim 9 engaging two bolts.
Claim 13
Dependent Claim
19 words
The header of claim 10 wherein said two bolts are seated toward lateral ends of the planar base member.
Claim 14
Dependent Claim
20 words
The header of claim 11 wherein each bolt has a washer mounted thereon between the bolt head and the spring.
Claim 15
Dependent Claim
51 words
The header of claim 12 wherein said bolt has a free end which is adapted to pass through a bore in said base member and engage within a corresponding bore in an underlying surface, the spring becoming compressed between said washer and said base member upon such engagement of the bolt.
