Embodiment Construction

[0018] Before describing the present invention in the most detail, it should be noted that in the various drawings, for the sake of clarity of description, the same parts having the same function are marked with the same reference numerals.

[0019] See Figures 1, 2 and 3 now. Shown in these figures is the arrangement for a quick release mechanism on a railcar hand brake. The railcar hand brake, generally designated "10", has a housing generally designated "11". The housing includes a front box 14 and a rear panel 13, wherein the front box 14 includes an inner wall 12 having a predetermined size and shape. A working shaft generally designated "20" is rotatably mounted on the housing 11. The working shaft 20 includes a first end 21 and a second end 22 . A ratchet 23 can rotate with the working shaft 20 and is located between the first end 21 and the second end 22 . A release shaft 40 is rotatably mounted in the housing 11 .

[0020] The device includes a protrusion 24 disp...

Abstract

An apparatus for a quick release mechanism in a railcar hand brake. The hand brake has a housing having a front casing with an inside wall of a predetermined size and shape, and a back plate. An operating shaft is rotatably mounted in the housing. The operating shaft includes a first end and a second end. The operating shaft further includes a ratchet wheel rotatable with the operating shaft intermediate the first and second ends thereof, and a release shaft rotatably mounted in the housing. The apparatus comprises a projection of a predetermined size and shape disposed substantially perpendicular to the ratchet wheel, and a flexible clamp of a predetermined size and shape mounted inside the housing. A member is disposed substantially perpendicular to, and about the circumference of the release shaft, having a first element disposed on the member wherein the first element interposes with the flexible clamp when the release shaft is rotated to achieve and maintain full brake release, and a second element disposed on the member and engageable with the projection when the operating shaft is rotated to disengage the first element from the flexible clamp to allow for brake application.

Description

technical field [0001] The invention disclosed in this application is closely related to the invention in co-pending patent application Ser. No. 09 / 664,210 entitled "Quick Release Mechanism for Railroad Car Hand Brake" filed concurrently with this application. This application has been assigned to the assignee of the present application. This co-pending patent application is incorporated herein by reference. [0002] This invention relates generally to a railroad car hand brake and, more particularly, to an arrangement for a quick release mechanism on a railroad car vertical wheel hand brake. The present invention will keep the hand brake in the released position before applying the brake. Background technique [0003] Prior to the present invention, a railcar vertical hand brake included a brake release mechanism that quickly released the brakes by disengaging the lift mechanism to allow free rotation of the main gear. A force is applied to the release lever to move the ...
