Abstract
Abstract A stillage for supporting stacked sheets comprising at least four co-planar members which are arranged so as to present to the sheets a platform area of rectangular outline, together with supports which are connected to the members, adjacent members being relatively movable to each other to vary the platform dimensions in two mutually perpendicular directions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
An adjustable stillage for supporting stacked metal sheets, comprising: at least four relatively movable, irregularly shaped members having substantially co-planar load bearing surfaces and movable to abut and form a substantially unbroken, rectangular, load bearing, minimum, platform area comprised of two transverse rectangular sections; each of said sections formed by two of said irregularly shaped members, a central elongate support means and two outside elongate support means aligned in the same direction and disposed below said members, said central support means being attached to all of said members and said outside support means each being attached to at least two of said members permitting the members to be relatively movable to each other to a limited extent to vary the platform area in two mutually perpendicular directions.
Claim 2
Dependent Claim
127 words
An adjustable stillage for supporting stacked metal sheets, comprising: at least four relatively movable, irregularly shaped members having substantially co-planar load bearing surfaces and movable to abut and form a substantially unbroken, rectangular, load bearing, minimum, platform area comprised of two transverse rectangular sections; each of said sections formed by two of said irregularly shaped members, a central elongate support means and two outside elongate support means aligned in the same direction and disposed below said members, said central support means being attached to all of said members and said outside support means each being attached to at least two of said members permitting the members to be relatively movable to each other to a limited extent to vary the platform area in two mutually perpendicular directions.
Claim 3
Dependent Claim
65 words
An adjustable stillage according to claim 1 in which one member of each of said transverse sections has a portion shaped to interlock upon abutment with a corresponding portion of the other member of the respective transverse section, each member being movable to separate the corresponding interlocked portions and increase the load bearing area, whereby the load bearing area is distributed in a uniform manner.
Claim 4
Dependent Claim
42 words
An adjustable stillage according to claim 2 in which each member is attached to at least two of said supports means, and the members are movable transversely of said central support means to vary the load bearing area in a transverse direction.
Claim 5
Dependent Claim
20 words
An adjustable stillage according to claim 3 in which each member is movable transversely of the associated outside support means.
Claim 6
Dependent Claim
42 words
An adjustable stillage according to claim 3 in which each of said support means comprises at least two interengagable and relatively movable support members, the members being movable with the support members to vary the load bearing area in a longitudinal direction.
Claim 7
Dependent Claim
23 words
An adjustable stillage according to claim 3 in which fastening means is provided for adjustably attaching the members to the central support means.
Claim 8
Dependent Claim
24 words
An adjustable stillage according to claim 4 in which fastening means is provided for adjustably attaching the members to the associated outside support means.
Claim 9
Dependent Claim
34 words
An adjustable stillage according to claim 1 in which the support means are movable transversely to a limited extent relative to each other, the members being movable with the supports in a transverse direction.
