Abstract
Abstract This development concerns load bracing members arranged vertically in a railroad freight car of the boxcar type. It is principally concerned with the loose mounting of said vertically disclosed load braces in related floor sockets so that said braces may easily be engaged and separated respectively when they are axially aligned. They are interfitted to accommodate movement of each brace in its floor socket, but yet inhibits inadvertent detachment therewith. That is said interfit of the braces and sockets at their lower ends accommodate lateral movement freely past axial alignment in any direction, particularly when they bear against cargo.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
252 words
A socket element for lodging in the floor or decking of a freight car for receiving and holding the lower end of an elongated, releasable stake constituting a load brace, comprising: a socket body having a marginal floor or decking engaging flange and a centrally depending pocket portion, said pocket portion having a floor section provided with an axially aligned aperture formed therein; an elongated, releasable vertically disposed stake having a lower end and mounted in the pocket portion of said socket; a terminal fitting carried by said lower end portion of said stake; said terminal fitting having a constricted neck portion and an underlying collar portion, said neck portion and collar portion being aligned in stacked relation with said terminal fitting; said terminal fitting having a cross-sectional area correlated with the pOcket portion of said socket, being of greater area than the aperture in the floor section of the pocket, the collar portion having a cross-sectional area less than that of the pocket aperture, and the neck portion having an area less than that of the collar portion, and having a length greater than the thickness of the floor section of the pocket, thereby to accommodate lateral movement of the latter post and when it is arranged in the pocket portion of the socket; and the terminal fitting part being thus proportioned with those of the pocket to prevent axial retraction of a post with its socket only when the axially aligned stacked parts are in vertical alignment with each other.
Claim 2
Dependent Claim
252 words
A socket element for lodging in the floor or decking of a freight car for receiving and holding the lower end of an elongated, releasable stake constituting a load brace, comprising: a socket body having a marginal floor or decking engaging flange and a centrally depending pocket portion, said pocket portion having a floor section provided with an axially aligned aperture formed therein; an elongated, releasable vertically disposed stake having a lower end and mounted in the pocket portion of said socket; a terminal fitting carried by said lower end portion of said stake; said terminal fitting having a constricted neck portion and an underlying collar portion, said neck portion and collar portion being aligned in stacked relation with said terminal fitting; said terminal fitting having a cross-sectional area correlated with the pOcket portion of said socket, being of greater area than the aperture in the floor section of the pocket, the collar portion having a cross-sectional area less than that of the pocket aperture, and the neck portion having an area less than that of the collar portion, and having a length greater than the thickness of the floor section of the pocket, thereby to accommodate lateral movement of the latter post and when it is arranged in the pocket portion of the socket; and the terminal fitting part being thus proportioned with those of the pocket to prevent axial retraction of a post with its socket only when the axially aligned stacked parts are in vertical alignment with each other.
Claim 3
Dependent Claim
268 words
A socket element for lodging in the floor or decking of a freight car for receiving and holding the lower end of an elongated, releasable stake constituting a load brace, comprising: a socket body having a marginal floor or decking engaging flange and a centrally depending pocket portion having a depth less than the thickness of the floor or decking of a freight car, said pocket portion having a floor section provided with an axially aligned aperture formed therein; an elongated, releasable vertically disposed stake having a lower end and mounted in the pocket portion of said socket; a terminal fitting carried by said lower end portion of said stake; said terminal fitting having a constricted neck portion and an underlying collar portion, said neck portion and collar portion being aligned in stacked relation with said terminal fitting; said terminal fitting having a cross-sectional area correlated with the pocket portion of said socket, being of greater area than the aperture in the floor section of the pocket, the collar portion having a cross-sectional area less than that of the pocket aperture, and the neck portion having an area less than that of the collar portion, and having a length greater than the thickness of the floor section of the pocket, thereby to accommodate lateral movement of the latter post and when it is arranged in the pocket portion of the socket; and the terminal fitting part being thus proportioned with those of the pocket to prevent axial retraction of a post with its socket only when the axially aligned stacked parts are in vertical alignment with each other.
Claim 4
Dependent Claim
268 words
A socket element for lodging in the floor or decking of a freight car for receiving and holding the lower end of an elongated, releasable stake constituting a load brace, comprising: a socket body having a marginal floor or decking engaging flange and a centrally depending pocket portion having a depth less than the thickness of the floor or decking of a freight car, said pocket portion having a floor section provided with an axially aligned aperture formed therein; an elongated, releasable vertically disposed stake having a lower end and mounted in the pocket portion of said socket; a terminal fitting carried by said lower end portion of said stake; said terminal fitting having a constricted neck portion and an underlying collar portion, said neck portion and collar portion being aligned in stacked relation with said terminal fitting; said terminal fitting having a cross-sectional area correlated with the pocket portion of said socket, being of greater area than the aperture in the floor section of the pocket, the collar portion having a cross-sectional area less than that of the pocket aperture, and the neck portion having an area less than that of the collar portion, and having a length greater than the thickness of the floor section of the pocket, thereby to accommodate lateral movement of the latter post and when it is arranged in the pocket portion of the socket; and the terminal fitting part being thus proportioned with those of the pocket to prevent axial retraction of a post with its socket only when the axially aligned stacked parts are in vertical alignment with each other.
Claim 5
Dependent Claim
47 words
The organization of claim 1, modified in that the pocket portion of the socket being of greater cross-sectional area than the lower end of the post to permit lateral movement of the post end in the socket, limited rotation therein, and gyration of the lateral axis thereof.
Claim 6
Dependent Claim
39 words
The organization of claim 1, modified in that the cross-sectional areas of the post, the pocket, the aperture in the floor of the socket, the neck portion of the terminal fitting, and the collar, all being of rectangular shape.
