Abstract

Apparatus for mounting an air brake cylinder to a bolster casting of a railroad car includes an adaptor mounting plate disposed contiguous to the surface of the bolster casting. The plate has a plurality of holes formed therein. The bolts are inserted through holes in the bolster casting and through the corresponding holes in the plate. Nuts are torqued onto the bolt shaft to secure the plate to the casting. The adaptor mounting plate also includes a plurality of threaded studs welded thereto. A flange is welded to the cylinder housing at the rod end of the cylinder. The flange has holes formed at its four corners. The flange and cylinder mate with the adaptor mounting plate such that the threaded studs on the plate are inserted through the corresponding holes in the flange. Nuts secure the flange to the plate. Holes are formed in the interior of the cylinder to accommodate the bolts and associated nuts securing the bolster casting to the plate. The apparatus of the present invention allows a single person to complete the entire assembly of the cylinder to the casting.

Claims

1. Apparatus for mounting a railroad air brake cylinder to a bolster casting of a railroad car, comprising:

a. a flange attached to the cylinder;

b. a mounting plate disposed between the flange and the bolster casting;

c. means for attaching the flange to the mounting plate; and

d. means for attaching the mounting plate to the bolster casting.

2. The apparatus of claim 1, wherein the means for attaching the flange to the mounting plate includes at least one bolt and corresponding nut.

3. The apparatus of claim 1, wherein the flange has at least one hole formed therein, and wherein the means for attaching the flange to the mounting plate includes at least one bolt and corresponding nut, the bolt being disposed through the corresponding hole in the flange.

4. The apparatus of claim 3, wherein the bolt is fixedly attached to the mounting plate.

5. The apparatus of claim 3, wherein the bolt is welded to the mounting plate.

6. The apparatus of claim 1, wherein the means for attaching the mounting plate to the bolster casting includes at least one bolt and corresponding nut.

7. The apparatus of claim 1, wherein the flange is disposed adjacent to and in abutting relation to the mounting plate, and wherein the mounting plate is disposed adjacent to and in abutting relation to the bolster casting.

8. The apparatus of claim 1, wherein the means for attaching the flange to the mounting plate comprises means for securing the flange adjacent to, and in an abutting relation to, the mounting plate.

9. The apparatus of claim 1, wherein the means for attaching the mounting plate to the bolster casting comprises means for securing the mounting plate adjacent to, and in abutting relation to, the bolster casting.

10. Apparatus for mounting a railroad air brake cylinder to a bolster casting of a railroad car, comprising:

a. a flange attached to the cylinder, the flange having a plurality of holes formed therein;

b. a mounting plate, disposed between the flange and the bolster casting, the mounting plate having a plurality of holes formed therein, the mounting plate having a plurality of bolts attached thereto, the bolts being inserted into the corresponding plurality of holes in the flange, the flange being secured to the mounting plate by nuts torqued onto the corresponding bolts attached to the plate and inserted into the plurality of holes in the flange; and

c. a plurality of bolts inserted both through corresponding holes in the bolster casting and through the corresponding holes in the mounting plate, the mounting plate being secured to the bolster casting by nuts torqued onto the bolts inserted through the holes in the bolster casting and the mounting plate.

11. The apparatus of claim 10, wherein the flange is disposed adjacent to and in abutting relation to the mounting plate, and wherein the mounting plate is disposed adjacent to and in abutting relation to the bolster casting.

12. The apparatus of claim 10, wherein the plurality of bolts are welded to the mounting plate.

13. Apparatus for mounting a railroad air brake cylinder to a bolster casting of a railroad car, comprising:

a. a flange attached to the cylinder, the flange having at least one hole formed therein;

b. a mounting plate, disposed between the flange and the bolster casting in a contiguous relationship therebetween, the mounting plate having at least one hole formed therein, the mounting plate having at least one bolt attached thereto, the bolt being inserted into the corresponding hole in the flange, the flange being secured to the mounting plate by a nut torqued onto the corresponding bolt attached to the mounting plate and inserted into the hole in the flange; and

c. at least one bolt inserted through the corresponding hole in the bolster casting and through the corresponding hole in the mounting plate, the mounting plate being secured to the bolster casting by a nut torqued onto the bolt inserted through the hole in the bolster casting and in the mounting plate.
