TILTABLE ROLLER ASSEMBLY

A tiltable roller assembly attachable to a door or window sash includes an attachment frame mountable on the door or window sash, a tilt frame loosely mounted in the attachment frame and tiltable in a first direction, a roller frame pivotally mounted on the tilt frame, and a roller rotatably supported on the roller frame. A pair of spaced blocks are mounted in said tilt frame, with the roller frame disposed between the spaced blocks, and there is an adjustment screw threadedly extending through a selected one of the blocks into abutting engagement with the roller frame. The roller frame is pivotably adjustable relatively to the second frame in a second direction transverse to the first direction, in response to turning of the adjustment screw. The attachment frame includes a pair of spaced sidewalls between which the tilt frame is disposed, there being spring means acting between one of the sidewalls and the spaced blocks and normally urging the tilt frame against the other sidewall.
