Abstract
A railroad brake stick can include: a head having a planar shape with a recesses and/or protrusions on one or more side surfaces of the planar shape, the planar shape having a head interlocking groove on a hilt region; a cross-support having a planar shape with a support interlocking groove interlocked with the head interlocking groove such that the planar shape of the head crosses with the planar shape of the cross-support to form an interlocking region; and a handle coupled to the head and cross-support such that the interlocking region is within an end of the handle. In some aspects, a cover is over the handle. n some aspects, the head is a composite material and the cross-support is a composite material and the handle is a composite material.
Claims25
A railroad brake stick comprising:
- a head having a planar shape with two planar surfaces and a head interlocking groove extending therebetween, and with a recess and/or protrusion on one or more side surfaces that extend between the two planar surfaces of the planar shape, the planar shape having the head interlocking groove on a hilt region;
- a cross-support having a planar shape with two planar surfaces and a support interlocking groove extending therebetween, wherein the support interlocking groove is interlocked with the head interlocking groove such that the planar shape of the head is received into the support interlocking groove and the planar shape of the cross-support is received into the head interlocking groove and the planar shape of the head crosses with the planar shape of the cross-support to form an interlocking region;
- and
- a handle fixedly coupled to the head and cross-support such that the interlocking region is within an end of the handle.
A railroad brake stick comprising:
- a head having a planar shape with two planar surfaces and a head interlocking groove extending therebetween, wherein the head interlocking groove on a hilt region, wherein the head is a first composite material;
- a cross-support having a planar shape two planar surfaces and a support interlocking groove extending therebetween, wherein the support interlocking groove is interlocked with the head interlocking groove to form an interlocking region, wherein the planar shape of the head is received into the support interlocking groove and the planar shape of the cross-support is received into the head interlocking groove, wherein the cross-support is a second composite material;
- and
- a handle coupled to the head and cross-support such that the interlocking region is within an end of the handle, wherein the handle is a third composite material.
