Abstract
Abstract A bracket assembly for supporting rollers to be received in tracks on a drawer includes a vertical wing and a horizontal wing integral with and projecting laterally from the lower edge of the vertical wing. At least two rollers are journaled on the vertical wing with one roller disposed adjacent each end of the vertical wing. A slot is formed transversely in the horizontal wing and a screw coacts with two flanges on the vertical wing, one on each side of the slot, whereby the screw may selectively move the flanges toward and away from each other thereby to change the width of the slot and adjust the relative positions of the rollers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A roller bracket assembly adapted to support a drawer for in and out sliding in an opening in a cabinet, said bracket assembly comprising a vertical wing, a horizontal wing integral with and projecting laterally from the lower edge of said vertical wing, a first roller journaled on one of said wings adjacent one end thereof, a second roller journaled on said one wing adjacent the other end thereof, one of said wings having a transverse slot disposed between said first and second rollers, and means on said one wing connecting said one wing on opposite sides of said slot, said means being selectively operable to increase or decrease the width of said slot and thereby bending said wings adjacent said slot and changing the position of said second roller relative to said first roller.
Claim 2
Dependent Claim
135 words
A roller bracket assembly adapted to support a drawer for in and out sliding in an opening in a cabinet, said bracket assembly comprising a vertical wing, a horizontal wing integral with and projecting laterally from the lower edge of said vertical wing, a first roller journaled on one of said wings adjacent one end thereof, a second roller journaled on said one wing adjacent the other end thereof, one of said wings having a transverse slot disposed between said first and second rollers, and means on said one wing connecting said one wing on opposite sides of said slot, said means being selectively operable to increase or decrease the width of said slot and thereby bending said wings adjacent said slot and changing the position of said second roller relative to said first roller.
Claim 3
Dependent Claim
60 words
A roller bracket assembly as defined in claim 1 in which said means includes a threaded member and parts on said one wing disposed on opposite sides of said slot, said threaded member being connected to said parts and being selectively operable to move said parts toward and away from each other thereby to change the width of said slot.
Claim 4
Dependent Claim
88 words
A roller bracket assembly as defined in claim 1 in which said means includes a first flange integral with said horizontal wing and disposed on one side of said slot, a second flange integral with said horizontal wing and disposed on the other side of said slot, and a screw projecting through one of said flanges and threaded into the other of said flanges whereby said screw may be turned to move said flanges toward and away from each other and thereby change the width of said slot.
Claim 5
Dependent Claim
30 words
A roller bracket assembly as defined in claim 3 in which said first roller is journaled on said first flange and said second roller is journaled on said second flange.
Claim 6
Dependent Claim
