Overload protection device for a truck-mounted brake assembly

An overload protection device for a truck-mounted railcar brake assembly, said overload protection device comprising:

• (a) a body member having a first end, a second end, and at least one cavity of a predetermined size and shape disposed within said body member;
• (b) a compression member of a predetermined size, shape, material, and load rating, said compression member compressed to a predetermined load, and disposed within said cavity of said body member;
• (c) a flange of a predetermined size and shape having a first surface and a second surface, said first surface disposed on said second end of said body member;
• (d) a first means secured to and disposed on said first end of said body member for engagement with a portion of such brake assembly;
• (e) a second means reciprocally mounted adjacent said second end of said body member for attaching to a force transmitting member, a first portion of said second means engageable with said compression member for transmitting an excess force generated from said force transmitting member to said compression member, said excess force being generated during application of such railcar brake assembly;
• and
• (f) a retaining element secured to and disposed on said second surface of said flange, said retaining element further having an aperture of a predetermined size and shape concentrically disposed therein, wherein a second portion of said second means is reciprocally disposed therein, whereby said overload protection device will compensate for a potential railcar brake overload condition.

An overload protection device for a truck-mounted railcar brake assembly, said overload protection device comprising:

• (a) a body member having a first end, a second end, and at least one cavity of a predetermined size and shape disposed within said body member;
• (b) a compression member of a predetermined size, shape, material, and load rating, having a concentric bore of a predetermined size and shape disposed within, compressed to a predetermined load, said compression member disposed within said cavity of said body member;
• (c) a first means secured to and disposed on said first end of said body member for engaging a portion of such brake assembly;
• (d) a second means disposed within said concentric bore of said compression member, engageable with said compression member and connectable to a force transmitting member;
• and
• (e) a retaining element secured to and disposed on said second end of said body member for securing said compression member in said cavity of said body member, whereby said overload protection device will compensate for a potential railcar brake overload condition during application of such railcar brake assembly.

An overload protection device for a truck-mounted railcar brake assembly, such truck-mounted railcar assembly including an air cylinder, an air cylinder transfer lever, a slack adjuster assembly, a non-air cylinder transfer lever and a force transfer lever positioned between such air cylinder and such non-air cylinder transfer lever, said overload protection device comprising:

• (a) a body member having a first end, a second end, and at least one cavity of a predetermined size and shape disposed within said body member;
• (b) a compression member of a predetermined size, shape, material, and load rating, said compression member compressed to a predetermined load, and disposed within said cavity of said body member;
• (c) a first means secured to and disposed on said first end of said body member for engagement with a portion of such non-air cylinder transfer lever;
• and
• (d) a second means disposed on said second end of said body member for attaching to such force transmitting member, a first portion of said second means engageable with said compression member for transmitting an excess force generated from said force transmitting member to said compression member, said excess force being generated during application of such railcar brake assembly, whereby said overload protection device will compensate for a potential railcar brake overload condition.
