Wheeled support for upright rolls

Claim 1

A device for supporting a roll of sheet material in an axially vertical position and for dispensing portions of said material from the said roll, comprising: frame means including a bottom member, a top member and interconnecting structure extenDing between and rigidly secured to said bottom member and said top member; lower spindle means mounted upon the bottom member and projecting upwardly therefrom for engaging and supporting said roll of sheet material; means defining a vertical opening through said top member coaxially aligned with the upright axis of said lower spindle, the distance between the upper end of said lower spindle and the lower side of the top member around said opening being greater than the length of the roll of sheet material; and an elongated upper spindle axially slideably disposed within said opening in said top member and having an enlargement spaced substantially from its lower end for positively limiting downward movement of said upper spindle through said opening, said upper spindle having a downwardly diverging portion spaced downwardly from said enlargement, the lower end of said diverging portion being larger than the diameter of said opening, whereby upward movement of said upper spindle beyond a predetermined distance wedges said upper spindle with respect to said top member.

Claim 2

A device for supporting a roll of sheet material in an axially vertical position and for dispensing portions of said material from the said roll, comprising: frame means including a bottom member, a top member and interconnecting structure extenDing between and rigidly secured to said bottom member and said top member; lower spindle means mounted upon the bottom member and projecting upwardly therefrom for engaging and supporting said roll of sheet material; means defining a vertical opening through said top member coaxially aligned with the upright axis of said lower spindle, the distance between the upper end of said lower spindle and the lower side of the top member around said opening being greater than the length of the roll of sheet material; and an elongated upper spindle axially slideably disposed within said opening in said top member and having an enlargement spaced substantially from its lower end for positively limiting downward movement of said upper spindle through said opening, said upper spindle having a downwardly diverging portion spaced downwardly from said enlargement, the lower end of said diverging portion being larger than the diameter of said opening, whereby upward movement of said upper spindle beyond a predetermined distance wedges said upper spindle with respect to said top member.

Claim 8

A device for supporting a plurality of relatively large and axially vertical rolls comprising: a substantially rectangular base frame including a bottom member; a top member vertically aligned with said bottom member, and upright members extending between and rigidly connected to said top member and said bottom member; a plurality of axially vertical lower spindles nonrotatably mounted upon said bottom member, each lower spindle having an integral, concentric and substantially circular flange spaced from the upper end thereof, and each flange having a portion of reduced radial extent on one side thereof; plural upper spindles vertically slideably supported upon said top member, each upper spindle having upper and lower enlarged portions preventing accidental disengagement thereof from said top member, and each upper spindle being coaxial with a lower spindle, the distance between each pair of upper and lower spindles, when said upper spindle is in its uppermost position, being greater than the axial length of a roll of sheet material to be supported therebetween; plural pairs of arms pivotally supported upon said top member and said base member, one pair of arms being adjacent each pair of upper and lower spindles; a cutter bar mounted upon and extending between each pair of upper and lower arms, said bar being positioned so that it will engage said portion of reduced radius on said flange means when the roll of sheet material is removed therefrom; and casters connected to and supporting the four corners of said base frame.

Claim 9

A device for supporting a plurality of relatively large and axially vertical rolls comprising: a substantially rectangular base frame including a bottom member; a top member vertically aligned with said bottom member, and upright members extending between and rigidly connected to said top member and said bottom member; a plurality of axially vertical lower spindles nonrotatably mounted upon said bottom member, each lower spindle having an integral, concentric and substantially circular flange spaced from the upper end thereof, and each flange having a portion of reduced radial extent on one side thereof; plural upper spindles vertically slideably supported upon said top member, each upper spindle having upper and lower enlarged portions preventing accidental disengagement thereof from said top member, and each upper spindle being coaxial with a lower spindle, the distance between each pair of upper and lower spindles, when said upper spindle is in its uppermost position, being greater than the axial length of a roll of sheet material to be supported therebetween; plural pairs of arms pivotally supported upon said top member and said base member, one pair of arms being adjacent each pair of upper and lower spindles; a cutter bar mounted upon and extending between each pair of upper and lower arms, said bar being positioned so that it will engage said portion of reduced radius on said flange means when the roll of sheet material is removed therefrom; and casters connected to and supporting the four corners of said base frame.
