Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
An end underframe structure for a railway car comprising: (a) a primary end sill extending transversely across the front of said car, (b) a secondary end sill spaced parallel said primary end sill, (c) a bolster member, (d) a first pair of side buffer members connecting said primary and secondary end sills, (e) a second pair of side buffer members connecting said secondary end sill to said bolster member, and (f) draft sill members centrally disposed between said first and second pairs of said side buffer members and extending longitudinally with respect to said car from the center of said primary end sill to the center of said bolster member.
Claim 2
Dependent Claim
110 words
An end underframe structure for a railway car comprising: (a) a primary end sill extending transversely across the front of said car, (b) a secondary end sill spaced parallel said primary end sill, (c) a bolster member, (d) a first pair of side buffer members connecting said primary and secondary end sills, (e) a second pair of side buffer members connecting said secondary end sill to said bolster member, and (f) draft sill members centrally disposed between said first and second pairs of said side buffer members and extending longitudinally with respect to said car from the center of said primary end sill to the center of said bolster member.
Claim 3
Dependent Claim
42 words
An end underframe structure as set forth in claim 1 wherein said first pair of side buffer members are connected longitudinally of said car substant-ially from the ends of said primary end sill substantially to the ends of said secondary end sill.
Claim 4
Dependent Claim
33 words
An end underframe structure as set forth in claim 2 wherein said second pair of side buffer members are connected longitudinally of said car from ends of said secondary sill to said bolster.
Claim 5
Dependent Claim
30 words
An end underframe structure as set forth in claim 3 wherein said first pair of side buffer members are disposed a door opening provided in an end of said car.
Claim 6
Dependent Claim
40 words
An end underframe structure as set forth in claim 4 wherein said first pair of side buffer members are recessed at an angle between said primary and secondary end sills to permit stairway attachments thereto and to provide wheel clearance.
Claim 7
Dependent Claim
23 words
An end underframe structure as set forth in claim 5 wherein said first and second side buffer members comprise relatively large tubular mem-bers.
Claim 8
Dependent Claim
54 words
An end underframe structure as set forth in claim 6 wherein a coupler carrier arrangement is disposed on said primary end sill in alignment with said draft sill to permit coupling elements to be set back into said coupler carrier so that forces exerted on said coupling element are trans-mitted to said draft sill.
Claim 9
Dependent Claim
42 words
An end underframe structure as set forth in claim 7 wherein said first and second side buffer members are longitudinally disposed with respect to said car in alignment with buffer elements adapted to be fitted to the bottom end of said car.
