Abstract
Abstract A clutch mechanism for securing a jewelry piece, such as a pierced earring, to a support member. The jewelry piece includes an elongated pin, and the clutch mechanism is slidably mounted on the pin in such a manner that it can readily be separated from the pin. The clutch mechanism includes a gripper portion for facilitating easy handling of the clutch, and it includes a flexible insert for frictionally gripping the pin.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A clutch mechanism for releasably gripping a jewelry pin comprising a housing having a first end and a second end, said first end constituting a gripper end and said second end constituting an abutment end, said gripper end being substantially enclosed and smaller than said abutment end, said housing being provided with an indentation which surrounds saId housing intermediate its ends and separates it into two portions, said indentation separating said housing into a gripper portion proximate said gripper end and a main body portion proximate said abutment end, both of said end portions being larger in crosssection than said indentation, at least the abutment end of said housing being provided with a bore therein, a closure member having a somewhat flattened surface, means for securing said closure member to the abutment end, said bore being formed in said closure member and a resilient insert having an elongated passage therein, said insert being positioned within said housing so that said passage is aligned with the bore in the closure member thereby forming a channel.
Claim 2
Dependent Claim
174 words
A clutch mechanism for releasably gripping a jewelry pin comprising a housing having a first end and a second end, said first end constituting a gripper end and said second end constituting an abutment end, said gripper end being substantially enclosed and smaller than said abutment end, said housing being provided with an indentation which surrounds saId housing intermediate its ends and separates it into two portions, said indentation separating said housing into a gripper portion proximate said gripper end and a main body portion proximate said abutment end, both of said end portions being larger in crosssection than said indentation, at least the abutment end of said housing being provided with a bore therein, a closure member having a somewhat flattened surface, means for securing said closure member to the abutment end, said bore being formed in said closure member and a resilient insert having an elongated passage therein, said insert being positioned within said housing so that said passage is aligned with the bore in the closure member thereby forming a channel.
Claim 3
Dependent Claim
61 words
The combination of claim 1 which includes a jewelry member which is provided with an elongated pin and an ornamental member, said pin having a slightly larger cross-sectional size than the size of the passage in the insert, said clutch mechanism and said jewelry member being connected together by inserting said elongated pin into the channel formed in the clutch mechanism.
Claim 4
Dependent Claim
43 words
The combination of claim 2 wherein said jewelry member constitutes a pierced earring and the clutch mechanism is provided for releasably securing said pierced earring to a wearer''s ear lobe, said ear lobe being interposed between the ornamental member and said clutch mechanism.
Claim 5
Dependent Claim
54 words
The combination of claim 1 wherein a bore is provided in the gripper end of the housing, said bore being aligned with the passage in the insert and the bore in the cap member, so that said elongated pin is permitted to extend through the channel formed by said bores and said insert passage.
Claim 6
Dependent Claim
38 words
The combination of claim 1 wherein the second end of the housing is provided with a surrounding flange, and the closure member constitutes a cap member which is connected to the housing by securing it to said flange.
Claim 7
Dependent Claim
46 words
The combination of claim 1 wherein said housing has a substantially circular cross-sectional shape, said indentation being in closer proximity to the gripper end than said abutment end, and said bore has a slightly larger cross-sectional size than the size of the passage in the insert.
