Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
282 words
An air brake arrangement comprising: an air brake cylinder mounted longitudinally of the car; an air brake piston extending outwardly from said air brake cylinder and connecting to a vertically extending floating cylinder lever; a slack adjuster connected to a midportion of the floating cylinder lever and extending a first direction; a first longitudinally extending brake rod connected to the distal end of said floating cylinder lever and extending in a second direction opposite to said first direction; said first longitudinally extending rod connected to a first vertically extending brake lever mounted at its opposite end on the car body; a second longitudinally extending brake rod connected to the midportion of said first vertically extending brake lever, and connected at its opposite end to a first vertically extending brake beam lever; said brake beam lever connected to a brake beam which applies the brakes to a wheel located on a first end of the car; said slack adjuster including a slack adjuster rod extending in said first direction and which is connected to at least one second vertically extending brake lever in the midportion of said second lever; a third longitudinally extending brake rod connected to the midportion of at least one of the second and a third vertically extending levers and extending longitudinally in the first direction; said third longitudinally extending brake rod connected at its opposite end to a vertically extending second brake beam lever; said second brake beam lever connected to a fulcrum means then connected to the truck frame; said second brake beam lever at its opposite end connected to a brake beam which applies the brakes to a wheel located on the second end of the car.
Claim 2
Dependent Claim
282 words
An air brake arrangement comprising: an air brake cylinder mounted longitudinally of the car; an air brake piston extending outwardly from said air brake cylinder and connecting to a vertically extending floating cylinder lever; a slack adjuster connected to a midportion of the floating cylinder lever and extending a first direction; a first longitudinally extending brake rod connected to the distal end of said floating cylinder lever and extending in a second direction opposite to said first direction; said first longitudinally extending rod connected to a first vertically extending brake lever mounted at its opposite end on the car body; a second longitudinally extending brake rod connected to the midportion of said first vertically extending brake lever, and connected at its opposite end to a first vertically extending brake beam lever; said brake beam lever connected to a brake beam which applies the brakes to a wheel located on a first end of the car; said slack adjuster including a slack adjuster rod extending in said first direction and which is connected to at least one second vertically extending brake lever in the midportion of said second lever; a third longitudinally extending brake rod connected to the midportion of at least one of the second and a third vertically extending levers and extending longitudinally in the first direction; said third longitudinally extending brake rod connected at its opposite end to a vertically extending second brake beam lever; said second brake beam lever connected to a fulcrum means then connected to the truck frame; said second brake beam lever at its opposite end connected to a brake beam which applies the brakes to a wheel located on the second end of the car.
Claim 3
Dependent Claim
50 words
An air brake arrangement according to claim 1, wherein the distal end of said second vertically extending lever is connected to short longitudinally extending brake rod which is connected to the distal end of a third vertically extending brake lever pivotably mounted at its upper end to the car body.
Claim 4
Dependent Claim
230 words
An air brake arrangement comprising: an air brake cylinder mounted longitudinally of the car; an air brake piston extending outwardly from said air brake cylinder and connected to a vertically extending floating cylinder lever; a slack adjuster connected to a midportion of the floating cylinder lever and extending a first direction; a first longitudinally extending brake rod means connected to the distal end of said floating cylinder lever and extending in a second direction opposite to said first direction; said first longitudinally extending rod means including at least one first vertically extending brake lever mounted at one end on the car body; said longitudinally extending brake rod means connected to a first vertically extending brake beam lever; said brake beam lever connected to a brake beam which applies the brakes to a wheel located on a first end of the car; said slack adjuster including a slack adjuster rod extending in said first direction and which is connected to second longitudinally extending brake rod means including at least one second vertically extending brake lever in the midportion of said second lever; said second longitudinally extending brake rod means connected at its opposite end to a vertically extending second brake beam lever; said second brake beam lever at its opposite end connected to a brake beam which applies the brakes to a wheel located on the second end of the car.
Claim 5
Dependent Claim
230 words
An air brake arrangement comprising: an air brake cylinder mounted longitudinally of the car; an air brake piston extending outwardly from said air brake cylinder and connected to a vertically extending floating cylinder lever; a slack adjuster connected to a midportion of the floating cylinder lever and extending a first direction; a first longitudinally extending brake rod means connected to the distal end of said floating cylinder lever and extending in a second direction opposite to said first direction; said first longitudinally extending rod means including at least one first vertically extending brake lever mounted at one end on the car body; said longitudinally extending brake rod means connected to a first vertically extending brake beam lever; said brake beam lever connected to a brake beam which applies the brakes to a wheel located on a first end of the car; said slack adjuster including a slack adjuster rod extending in said first direction and which is connected to second longitudinally extending brake rod means including at least one second vertically extending brake lever in the midportion of said second lever; said second longitudinally extending brake rod means connected at its opposite end to a vertically extending second brake beam lever; said second brake beam lever at its opposite end connected to a brake beam which applies the brakes to a wheel located on the second end of the car.
Claim 6
Dependent Claim
25 words
An air brake arrangement according to claim 3, wherein said second brake beam lever is connected to a fulcrum means connected to the car body.
