Abstract
Abstract A cartridge pin mounting wherein a cartridge pin is secured in accurately preselected relationship to a frame having a mounting hole opening through an outer surface thereof. An outer surface associated with the pin is urged into flush relationship with the outer surface of the frame by a retainer which, in turn, is locked in the frame opening by a suitable locking ring. The outer surface of the pin may be defined by a ring structure at the outer end of the pin, and in the illustrated embodiment, the pin projects slightly from the ring portion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A cartridge pin mounting wherein a cartridge pin is secured in accurately preselected relationship to a frame portion having a mounting hole opening outwardly through an outer surface thereof, said mounting comprising: surface means on said pin defining an outwardly longitudinally facing outer end surface and a radially outer peripheral surface complementary to said mounting hole, said surface means being installed in said mounting hole with said outer end surface flush with said frame outer surface to provide a preselected accurate mounting of said pin in said frame portion hole; and retaining means on said frame portion longitudinally outwardly of said frame outer surface for maintaining the surface means against undesirable longitudinally outward displacement and thereby maintain the flush disposition of said surface means outer end surface and said frame outer surface.
Claim 2
Dependent Claim
132 words
A cartridge pin mounting wherein a cartridge pin is secured in accurately preselected relationship to a frame portion having a mounting hole opening outwardly through an outer surface thereof, said mounting comprising: surface means on said pin defining an outwardly longitudinally facing outer end surface and a radially outer peripheral surface complementary to said mounting hole, said surface means being installed in said mounting hole with said outer end surface flush with said frame outer surface to provide a preselected accurate mounting of said pin in said frame portion hole; and retaining means on said frame portion longitudinally outwardly of said frame outer surface for maintaining the surface means against undesirable longitudinally outward displacement and thereby maintain the flush disposition of said surface means outer end surface and said frame outer surface.
Claim 3
Dependent Claim
68 words
The cartridge pin mounting of claim 1 wherein said retaining means comprises a press member adapted to urge said surface means outer end surface longitudinally inwardly into the flush disposition relative to said frame outer surface, and a locking member removably mounted to the frame longitudinally outwardly of said press member for maintaining said press member in installed retaining disposition relative to said surface means inner end surface.
Claim 4
Dependent Claim
19 words
The cartridge pin mounting of claim 1 wherein said surface means comprises a collar fixedly carried on said pin.
Claim 5
Dependent Claim
24 words
The cartridge pin mounting of claim 1 wherein said surface means comprises an annular member fixedly secured to the outer end of the pin.
Claim 6
Dependent Claim
22 words
The cartridge pin mounting of claim 1 wherein said pin includes an outer end portion projecting longitudinally outwardly of said surface means.
Claim 7
Dependent Claim
37 words
The cartridge pin mounting of claim 1 further including a bushing receiving said pin longitudinally inwardly of the surface means and said surface means is provided with seal means for sealing said surface means to the bushing.
Claim 8
Dependent Claim
74 words
The cartridge pin mounting of claim 1 wherein said retaining means comprises a press member adapted to urge said surface means outer end surface longitudinally inwardly into the flush disposition relative to said frame outer surface, and a locking member for maintaining said press member in retaining disposition relative to said surface means inner end surface, said locking member comprising a snap ring removably secured to said frame longitudinally outwardly of said press member.
Claim 9
Dependent Claim
40 words
The cartridge pin mounting of claim 1 wherein said pin defines a planar outer end surface spaced from the plane of said frame outer surface when said surface means outer end surface is disposed flush with said frame outer surface.
Claim 10
Dependent Claim
18 words
The cartridge pin mounting of claim 1 wherein said surface means comprises a ring press-fitted to said pin.
