Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
In apparatus for supporting and conveying glass sheets including a plurality of conveyor rolls each comprising an inner core member and an outer load supporting sleeve, means including a tubular drive member for rotating said sleeve about said inner core member, and means connecting said tubular drive member to one end of each inner core member for rotation thereof relative to said core member: the improvement wherein said connecting means comprises a tubular extension affixed to said drive member for rotation therewith and a coupling having a first section secured to one end of said inner core member and a second section mounted within said tubular extension, and means detachably connecting said first and second coupling sections together.
Claim 2
Dependent Claim
118 words
In apparatus for supporting and conveying glass sheets including a plurality of conveyor rolls each comprising an inner core member and an outer load supporting sleeve, means including a tubular drive member for rotating said sleeve about said inner core member, and means connecting said tubular drive member to one end of each inner core member for rotation thereof relative to said core member: the improvement wherein said connecting means comprises a tubular extension affixed to said drive member for rotation therewith and a coupling having a first section secured to one end of said inner core member and a second section mounted within said tubular extension, and means detachably connecting said first and second coupling sections together.
Claim 3
Dependent Claim
32 words
An apparatus according to claim 1, wherein said detachably connecting means comprises a socket in said first coupling section and a lug formed on said second coupling section insertable in said socket.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 2, wherein said socket and lug have complimentary shaped flat sides, respectively, allowing axial movement but preventing relative rotation therebetween.
Claim 5
Dependent Claim
36 words
An apparatus according to claim 1, wherein said first coupling section is formed with a cylindrical body having a reduced diameter portion fitted within said one end of said inner core member and rigidly secured therein.
Claim 6
Dependent Claim
28 words
An apparatus according to claim 1, wherein said second coupling section comprises an elongated body having a reduced diameter portion mounted within bearings seated in said tubular extension.
Claim 7
Dependent Claim
40 words
An apparatus according to claim 5, wherein said elongated body is formed with a cylindrical flange intermediate the opposite ends thereof and a lug extending axially from said flange and insertable into a socket formed in said first coupling section.
Claim 8
Dependent Claim
124 words
An apparatus according to claim 1, wherein said first coupling section is formed with a cylindrical body having a reduced diameter portion fitted within said one end of said inner core member and rigidly secured therein, said second coupling section comprises an elongated body having a cylindrical flange intermediate the opposite ends thereof and a reduced diameter portion projecting axially in one direction from said flange and mounted within bearings seated in said tubular extension, and said detachably connecting means comprises a socket formed in said cylindrical body of said first coupling section and a lug formed on said second coupling section and extending axially from said flange in a direction opposite to said second coupling reduced diameter portion and insertable into said socket.
