Abstract
Abstract A split beveled retaining ring and method for constructing the same is characterized by a beveled groove seating flange being formed by bending the radially inner or outer edge portion of a split ring body at an angle to the plane of the ring body. The part abutment surface of the ring body may be maintained in substantially the same plane as the terminal portion of the bent beveled flange either by indenting the ring body to form a new part abutment surface or by bending the groove seating flange twice in opposite directions.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
92 words
A split retaining ring comprising a generally circular body having a plurality of circumferentially spaced grooves in the radially inner or outer edge of said body, said grooves being divided by prongs which are uniformly bent at an abgle to the ring body to form groove reception flanges having inclined groove seating surfaces, said prongs being uniformly bent twice in opposite directions to form V shape members with the free legs thereof forming the groove reception flanges which are substantially coplanar at the ends thereof with one sidewall of the ring body.
Claim 2
Dependent Claim
92 words
A split retaining ring comprising a generally circular body having a plurality of circumferentially spaced grooves in the radially inner or outer edge of said body, said grooves being divided by prongs which are uniformly bent at an abgle to the ring body to form groove reception flanges having inclined groove seating surfaces, said prongs being uniformly bent twice in opposite directions to form V shape members with the free legs thereof forming the groove reception flanges which are substantially coplanar at the ends thereof with one sidewall of the ring body.
Claim 3
Dependent Claim
48 words
The split retaining ring of claim 1 wherein said body has a uniform cross section from end to end, and said grooves increase in depth from the center to the free ends of the ring body to maintain the circularity of the same during distortion of the ring.
Claim 4
Dependent Claim
87 words
A split retaining ring comprising a generally circular body having a plurality of circumferentially spaced grooves in the radially inner or outer edge of said body, said grooves being divided by prongs which are uniformly bent at an angle to the ring body to form groove reception flanges having inclined groove seating surfaces, and a plurality of circumferentially spaced projecting surfaces extending axially from one sidewall of said ring body, said projecting surfaces being substantially coplanar with the free terminal portions of the inclined groove reception flanges.
Claim 5
Dependent Claim
87 words
A split retaining ring comprising a generally circular body having a plurality of circumferentially spaced grooves in the radially inner or outer edge of said body, said grooves being divided by prongs which are uniformly bent at an angle to the ring body to form groove reception flanges having inclined groove seating surfaces, and a plurality of circumferentially spaced projecting surfaces extending axially from one sidewall of said ring body, said projecting surfaces being substantially coplanar with the free terminal portions of the inclined groove reception flanges.
Claim 6
Dependent Claim
25 words
The split retaining ring of claim 3 wherein said projecting surfaces on said body are in radial alignment with said prongs and radially spaced therefrom.
Claim 7
Dependent Claim
47 words
The split retaining ring of claim 3 wherein said body has a uniform cross section from end to end, and said grooves increase in depth from the center to the free ends of said body to maintain the circularity of the same during distortion of the ring.
Claim 8
Independent Claim
81 words
A method of forming a beveled split retaining ring including a ring body and a plurality of circumferentially spaced grooves along the radially inner or outer edge of the ring body divided by prongs comprising the step of uniformly bending the prongs between the grooves to form a beveled groove seating flange having an inclined seating surface, said prongs being bent twice in different directions so that the free ends thereof are substantially coplanar with one sidewall of the ring body.
Claim 9
Independent Claim
81 words
A method of forming a beveled split retaining ring including a ring body and a plurality of circumferentially spaced grooves along the radially inner or outer edge of the ring body divided by prongs comprising the step of uniformly bending the prongs between the grooves to form a beveled groove seating flange having an inclined seating surface, said prongs being bent twice in different directions so that the free ends thereof are substantially coplanar with one sidewall of the ring body.
Claim 10
Dependent Claim
35 words
The method of claim 6 wherein the ring body has a uniform cross section from end to end, and the grooves increase in depth from the center to the free ends of the ring body.
Claim 11
Independent Claim
85 words
A method of forming a beveled split retaining ring comprising the steps of uniformly bending a radially inner or outer edge portion of the ring body relative to the plane of the ring body to form a beveled groove seating flange having an inclined seating surface, and forming a plurality of circumferentially spaced projecting surfaces on the ring body extending axially from one sidewall of the ring body, said projecting surfaces being substantially coplanar with the free terminal portion of the beveled groove seating flange.
Claim 12
Independent Claim
85 words
A method of forming a beveled split retaining ring comprising the steps of uniformly bending a radially inner or outer edge portion of the ring body relative to the plane of the ring body to form a beveled groove seating flange having an inclined seating surface, and forming a plurality of circumferentially spaced projecting surfaces on the ring body extending axially from one sidewall of the ring body, said projecting surfaces being substantially coplanar with the free terminal portion of the beveled groove seating flange.
Claim 13
Dependent Claim
30 words
The method of claim 8 wherein the projecting surfaces are formed by providing a plurality of indentations in the other sidewall of the ring body directly opposite the projecting surfaces.
Claim 14
Dependent Claim
63 words
The method of claim 9 wherein there are a plurality of circumferentially spaced grooves along the radially inner or outer edge of the ring body which are divided by prongs uniformly bent to form such beveled groove seating flange, and the indentations and thus the projecting surfaces are formed in the ring body in radial alignment with the prongs and radially spaced therefrom.
