Abstract
Abstract A lading filler having a frame which is either stationarily mounted on a wall of a railway car or the like or is moveable along a sidewall on elongated tracks. A panel is adjustably mounted on the frame by two sets of moveable crossed arms and each set is connected by a pair of moveable tie bars. A locking arrangement is provided for locking the panel in one of its adjusted positions which includes a member which is moveable by and in the same direction as ends of the crossed arms. Further latching means are provided for locking the panel to the frame and for preventing movement along the sidewall.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
360 words
In a lading filler adapted to be stored in closely spaced relation to a wall of a freight-carrying vehicle and adapted to Move to selected positions spaced from and parallel to the stored position under the guidance of at least one pair of pivoted arms, the improvement comprising, in combination: rigid frame means arranged to lie in a plane parallel to and spaced from said wall and adapted to move toward and away from said wall, elongated slideway means attached to said rigid frame means for movement therewith and located between the vertical planes of the frame means and the wall, brace means pivotally attached intermediate the ends of one of said pair of arms and having one end connected at one of said frame means and said wall, an elongated tie bar means pivotally connected between said pair of pivoted arms and located adjacent and substantially parallel to said slideway means and including means cooperating with said slideway means to render said tie bar means moveable only in opposite vertical directions substantially parallel to said slideway means, said pair of arms being in continuous spaced parallel relationship to each other and inclined to the planes of said frame means and said wall and each pivotally connected adjacent one end to said tie bar means and pivoted at their other end adjacent said wall whereby the frame means may move relative to the wall in directions perpendicular to the planes of the frame means and the wall while causing sliding of the tie bar means and pivoting of the spaced arms about their respective pivot axes, locking bar means pivotally attached to at least one of said arms and moveable in the same direction as said one arm end in a direction substantially parallel to said frame means, and locking means carried on said frame means and being moveable to a first position in which said locking means engages said locking bar means in at least one of a plurality of positions to lock the frame means a predetermined distance from the wall and being moveable to a second position to disengage said locking means from said locking bar means.

Dependent Claim
360 words
In a lading filler adapted to be stored in closely spaced relation to a wall of a freight-carrying vehicle and adapted to Move to selected positions spaced from and parallel to the stored position under the guidance of at least one pair of pivoted arms, the improvement comprising, in combination: rigid frame means arranged to lie in a plane parallel to and spaced from said wall and adapted to move toward and away from said wall, elongated slideway means attached to said rigid frame means for movement therewith and located between the vertical planes of the frame means and the wall, brace means pivotally attached intermediate the ends of one of said pair of arms and having one end connected at one of said frame means and said wall, an elongated tie bar means pivotally connected between said pair of pivoted arms and located adjacent and substantially parallel to said slideway means and including means cooperating with said slideway means to render said tie bar means moveable only in opposite vertical directions substantially parallel to said slideway means, said pair of arms being in continuous spaced parallel relationship to each other and inclined to the planes of said frame means and said wall and each pivotally connected adjacent one end to said tie bar means and pivoted at their other end adjacent said wall whereby the frame means may move relative to the wall in directions perpendicular to the planes of the frame means and the wall while causing sliding of the tie bar means and pivoting of the spaced arms about their respective pivot axes, locking bar means pivotally attached to at least one of said arms and moveable in the same direction as said one arm end in a direction substantially parallel to said frame means, and locking means carried on said frame means and being moveable to a first position in which said locking means engages said locking bar means in at least one of a plurality of positions to lock the frame means a predetermined distance from the wall and being moveable to a second position to disengage said locking means from said locking bar means.
Claim 3
Dependent Claim

The filler of claim 1 wherein said locking means includes an eccentric surface which frictionally engages said locking bar means when said locking means is in said first position.
Claim 4
Dependent Claim
37 words
The filler of claim 1 wherein said locking bar means includes a plurality of ratchet teeth and said locking means includes a pawl which engages said rachet teeth when said locking means is in said first position.
Claim 5
Dependent Claim
48 words
The filler of claim 1 wherein said plurality of positions are defined by a plurality of apertures on said locking bar means and said locking means includes a pin which is inserted in a selected one of said apertures when said locking means is in said first position.
Claim 6
Dependent Claim

The filler of claim 4 wherein said slideway means comprises a pair of guide channels, and said locking bar means comprises a single bar located between said channels and substantially parallel thereto.
Claim 7
Dependent Claim
27 words
The filler of claim 5 including shock absorbing means mounting said locking bar to said one end of one of said arms which slide adjacent said panel.
Claim 8
Dependent Claim
38 words
The filler of claim 1 wherein said locking means includes urging means normally urging said locking means into said first position, and lever means for overcoming said urging means to move said locking means to said second position.
Claim 9
Dependent Claim
18 words
The filler of claim 1 wherein said locking bar means are defined by said elongated tie bar means.
Claim 10
Dependent Claim
163 words
The filler of claim 1 including: second rigid frame means adjacent said wall, each of said arms being pivotally mounted at their said other ends on said second frame means, track means mounted adjacent said wall, mounting means moveably mounting said second frame means on said track means for longitudinal movement therealong, frame locking means mounted on said second frame means for locking said second frame means to prevent said longitudinal movement thereof, guide means spaced vertically from said track means for guiding said second frame means in said longitudinal movement, said track means and said guide means including a plurality of spaced apertures, said fRame locking means including a pair of pins one of which is normally urged into one of the apertures in said track means and the other of which is normally urged into one of the apertures in said guide means, each of said pins preventing said longitudinal movement, and means for simultaneously withdrawing said pins from the apertures.
Claim 11
Dependent Claim
38 words
