Railway car

Claim 2

An end of car draft and cushion unit for a railway car having a sill with an open end at one end of the car, a draft gear having travel in draft and in buff relative to said open end of the sill, an elastomeric shear sandwich mounting within said open end of the sill having a pair of members anchored to spaced portions of a body of elastomer which is stressed in shear by relative movement of said members along the axis of the sill, a coupler outside the sill, means for connecting the coupler in draft and buff thrust relationship to the draft gear, stop means on said sill at said one end of the car for receiving draft forces from the draft gear, means for connecting one of said pair of members in fixed relation to the sill at said one end of the car, means for connecting the other of said pair of members in buff stress receiving relationship to the draft gear whereby the elastomer is stressed in shear by buff stresses to provide cushion travel in addition to the draft gear travel, said coupler being spaced from said one end of the sill to accommodate draft gear and cushion travel, and said body of elastomer being initially stressed to hold the draft gear against said stop means.

Claim 3

The unit of claim 1 in which the draft gear has a yoke connected in draft and buff relationship to the coupler and in which the means for connecting the other member in buff stress receiving relationship to the draft gear comprises a thrust member in thrust relation between the yoke and the other member, said yoke and said thrust member being movable relative to each other, said yoke and sill having stops engaging to limit the movement of the yoke relative to said thrust member in buff.

Claim 4

The unit of claim 1 in which the draft gear has a yoke connected in Draft and buff relationship to the coupler and in which the means for connecting the other member in buff stress receiving relationship to the draft gear comprises a second yoke in draft and buff relation to the draft gear and to said other member, said yokes being movable relative to each other and having stops engaging to limit the movement of the draft gear yoke relative to the second yoke in buff.

Claim 5

An end of car draft and cushion unit for a railway car having a sill with an open end at one end of the car, a draft gear having travel in draft and in buff relative to said open end of the sill, a plurality of elastomeric shear sandwich mountings within said open end of the sill arranged respectively above and below an H-beam extending lengthwise of the sill and between said H-beam and upper and lower channels extending lengthwise of the sill and having flanges presented to and frictionally engaging upper and lower flanges of said H-beam, each mounting having a body of elastomer which has spaced portions anchored respectively to said H-beam and to one of the channels and which is stressed in shear by relative movement of said channels and H-beam along the axis of the sill, a coupler outside the sill, means for connecting the coupler in draft and buff thrust relationship to the draft gear, stop means on said sill at said one end of the car for receiving draft forces from the draft gear, means for connecting said channels in fixed relation to the sill at said one end of the car, means for connecting said H-beam in buff stress receiving relationship to the draft gear whereby the elastomer is stressed in shear by buff stresses to provide cushion travel in addition to the draft gear travel, said coupler being spaced from said one end of the sill to accommodate draft gear and cushion travel, and said bodies of elastomer being initially stressed to hold the draft gear against said stop means.

Claim 6

An end of car draft and cushion unit for a railway car having a sill with an open end at one end of the car, a draft gear having travel in draft and in buff relative to said open end of the sill, a plurality of elastomeric shear sandwich mountings within said open end of the sill arranged respectively above and below an H-beam extending lengthwise of the sill and between said H-beam and upper and lower channels extending lengthwise of the sill and having flanges presented to and frictionally engaging upper and lower flanges of said H-beam, each mounting having a body of elastomer which has spaced portions anchored respectively to said H-beam and to one of the channels and which is stressed in shear by relative movement of said channels and H-beam along the axis of the sill, a coupler outside the sill, means for connecting the coupler in draft and buff thrust relationship to the draft gear, stop means on said sill at said one end of the car for receiving draft forces from the draft gear, means for connecting said channels in fixed relation to the sill at said one end of the car, means for connecting said H-beam in buff stress receiving relationship to the draft gear whereby the elastomer is stressed in shear by buff stresses to provide cushion travel in addition to the draft gear travel, said coupler being spaced from said one end of the sill to accommodate draft gear and cushion travel, and said bodies of elastomer being initially stressed to hold the draft gear against said stop means.

Claim 7

The unit of claim 4 in which the upper channel and H-beam extend over the car center plate and the lower channel is inward of the car center plate.
