Abstract

A quick release brake mechanism has a housing, a first shaft mounted in the housing and at least one gear rotatably received thereon. A second gear is rotatably mounted in the housing in operative engagement with the first shaft. A clutch is operatively disposed between the first shaft and the second gear, and a locking mechanism is mounted in the housing in operative engagement with the first shaft at least one gear and the clutch. The clutch is moveable between a first position in which the first shaft is rotationally coupled to the first and the second gears, and a second position in which the second gear rotates with respect to the first shaft. A remotely operated quick release mechanism operatively coupled to the housing has a first end operatively coupled to a power source and an opposite second end operatively coupled to the clutch so as to move the clutch from the clutch first position into the clutch second position.

Claims20

Dependent claims

A brake mechanism for connecting to the brake rigging of a railway car, said brake mechanism comprising:

a. a housing;
b. a first handle;
c. a first shaft mounted in said housing and coupled to said first handle, said first shaft having at least one gear rotatably received thereon;
d. a second gear rotatably mounted in said housing in operative engagement with said first shaft;
e. a locking mechanism mounted in said housing and in operative engagement with said first shaft at least one gear, said locking mechanism comprising
(i) a second shaft mounted in said housing,
(ii) a first pawl rotatably received on said second shaft and in operative engagement with said first shaft at least one gear,
(iii) a second pawl having a first portion and a second portion, said first portion being in operative engagement with said first pawl, and
f. a clutch operatively disposed between said first handle and said second gear, said clutch being in operative engagement with said second pawl second portion, wherein said clutch is moveable between
a first position in which said first shaft is rotationally coupled to said first and said second gears, and
a second position in which said second gear rotates with respect to said first shaft;
and
g. a remotely operated quick release mechanism operatively coupled to said housing, said remotely operated quick release mechanism having a first end operatively coupled to a power source and an opposite second end operatively coupled to said clutch so as to move said clutch from said clutch first position into said clutch second position.

A quick release brake mechanism for use on a railway car, said brake mechanism comprising:

a. a housing;
b. a first shaft mounted in said housing and having at least one gear rotatably received thereon;
c. a second gear rotatably mounted in said housing in operative engagement with said first shaft;
d. a clutch operatively disposed between said first shaft and said second gear,
e. a locking mechanism mounted in said housing and in operative engagement with said first shaft at least one gear and said clutch, wherein said clutch is moveable between
a first position in which said first shaft is rotationally coupled to said first and said second gears, and
a second position in which said second gear rotates with respect to said first shaft;
and
f. a remotely operated quick release mechanism operatively coupled to said housing, said remotely operated quick release mechanism having a first end operatively coupled to a power source and an opposite second end operatively coupled to said clutch so as to move said clutch from said clutch first position into said clutch second position.

6 more elements

A method for releasing a railway brake remotely from the railway car, said method comprising the steps of:

a. providing a brake mechanism for connecting to the brake rigging of a railway car, said brake mechanism comprising:
(i) a housing;
(ii) a first shaft mounted in said housing and having at least one gear rotatably received thereon;
(iii) a second gear rotatably mounted in said housing in operative engagement with said first shaft;
(iv) a clutch operatively disposed between said first shaft and said second gear,
(v) a locking mechanism mounted in said housing and in operative engagement with said first shaft at least one gear and said clutch, wherein said clutch is moveable between
a first position in which said first shaft is rotationally coupled to said first and said second gears, and
a second position in which said second gear rotates with respect to said first shaft;
and
(vi) a remotely operated quick release mechanism having a first end operatively coupled to a compressed air source and an opposite second end operatively coupled to said clutch;
b. actuating said quick release mechanism from a remote location so that said clutch is moved from said first position into said second position.
