## Abstract

Concerning the operating of floating levers 120 and 120', when wheel 14 is rotated to apply hand brakes, the cylinder lever 120 operates precisely as if an air brake application had been made. As tension in the rods 122 and the slack adjuster 140 increase, link 123 no longer supports the weight or the slack adjuster 140 because the system is in equilibrium. Positions and ratios are so balanced that the push rod 68 centers in the hollow rod without link 123. Link 123 is necessary to the operation of the system only at release. As tension in the rod 122 and slack adjuster 140 decreases (by release of the brake) vertical up load components on the cylinder lever 122 decrease. Link 123 pivots to a vertical position and assumes the load of the cylinder lever 122 and slack adjuster 140. The pivot point 123b of link 123 is so located that as the brake rigging relaxes (i.e. as brake forces are released) the slack adjuster weight is supported and the lever 120 further rotates allowing the push rod 68 to return back into the hollow rod 70.

## Background
## Claims

1. A hand brake assembly for use with separate railway cars or articulated car units comprising: said wheel assembly to a first force dividing means located on the first car which divides the applied hand brake force into first and second hand brake linkages; each having a reduced hand brake force; said first hand brake linkage connected to a first air brake linkage means located on the first car; whereby when the hand brake is applied, said first hand brake linkage is effective to apply the brakes on the first car or unit through said first air brake linkage; said second hand brake linkage extending from one car to a second adjacent car; means connecting said second hand brake linkage to a force multiplying means provided on the second car which increases the and brake force of the second hand brake linkage to a level sufficient to apply the brakes on the second car through a second air brake linkage means located on the second car.

2. A hand brake assembly according to claim 1, wherein the force multiplying means increases the hand brake force to a level substantially equal to the originally applied hand brake force.

3. A hand brake assembly according to claim 1, wherein said force multiplying means is connected to a third hand brake linkage located on the second car linkage means; said third hand brake linkage means connected to a second force dividing means which divides the hand brake force coming from said force multiplying means into fourth and fifth hand brake linkage means.

4. A hand brake assembly according to claim 3, wherein said fourth hand brake linkage is connected to a second air brake linkage means to apply the hand brake force to the second car through second air brake linkage means.

5. A hand brake assembly according to claim 4, wherein said fifth hand brake linkage means extends to a third car to apply the hand brake force on the third car.

6. A hand brake assembly according to claim 5, wherein said fifth hand brake linkage means is connected to third force multiplying means provided on said third car which functions on the third to apply the hand brake force in said fifth hand brake linkage means to a lever sufficient to apply the hand brake force in the third car.

7. A hand brake assembly according to claim 4, wherein said fifth hand brake linkage is removably connected to the second car.

8. A hand brake assembly according to claim 1, including lever means located between said wheel assembly and said first force dividing means to adjust the applied hand brake force to a suitable brake application level, and which lever means avoid interference with structure on said first cars.

9. A hand brake assembly for use with separate railway cars or articulated car units comprising: a wheel assembly mounted adjacent one end of the first car; connecting said wheel assembly to a force dividing means provided on said first car which divides the applied hand brake force into the first and second hand brake linkages, each having a reduced hand brake force; said first hand brake linkage means connected to first air brake linkage means located on the first car at least partially within an air brake cylinder; whereby when said hand brake assembly is applied, said first hand brake linkage is effective to apply the brakes on the first car through said first air brake linkages; said second hand brake linkage extending from one car to a second adjacent car; means connecting said second hand brake linkage to a force multiplying means located on the second car which increases the hand brake force of the second hand brake linkage to a level sufficient to apply the brakes on the second car; third hand brake linkage means connecting said force multiplying means to a second force dividing means located on said second car; said second force dividing means connected to a fourth hand brake linkage means connected to second air brake linkage means; whereby to apply the brakes on said second car; said second force dividing means also connected to fifth hand brake linkage means extending longitudinally of the car.

10. A hand brake assembly according to claim 9, wherein said fifth hand brake linkage extends to a third car to apply the hand brake force on the third car.

11. A hand brake assembly according to claim 10, wherein said fifth hand brake linkage means is connected to a second force multiplying means provided on the third car which functions to apply the hand brake force in said fifth hand brake linkage means.

12. A hand brake assembly according to claim 9, wherein said fifth hand brake linkage means is removable connected to the second car.

13. A hand brake assembly according to claim 9, wherein said first air brake linkage means includes at least a portion located within an air brake cylinder.

14. A hand brake assembly according to claim 13, wherein said air brake linkage means is also at least partially located within an air brake cylinder.

15. A hand brake assembly according to claim 9, wherein said second force multiplying means increases the brake force to substantiate the originally applied hand brake force.

16. A hand brake arrangement according to claim 1, including chain means extending from said hand brake wheel to a horizontally extending lever pivotally mounted upon a car body.

17. A hand brake arrangement according to claim 16, wherein at the midpoint of said horizontally extending lever, a longitudinally extending brake rod is connected located between a wheel and other structure on the car bottom.

18. A hand brake arrangement according to claim 17, wherein said rod is connected to a second horizontally extending brake rod pivotally mounted on the car.

19. A hand brake arrangement according to claim 18, wherein said second horizontally extending brake lever is pivotally mounted on an opposite side than said first hand brake lever.

20. A hand brake system according to claim 19, wherein said first horizontally extending rod increases the hand brake force applied.

21. A hand brake arrangement according to claim 20, wherein said second horizontally extending brake lever reduces the applied hand brake force.

22. A hand brake arrangement according to claim 18, wherein said second hand brake lever is connected to a longitudinally extending rod which in turn is connected to said first force dividing means.
