<p>A disc record cleaning mechanism particularly adapted to be used with a disc record player having a hinged cover and arranged to be wholly lifted upon opening of the cover and which responds to opening of the latter, and to an effective weight, to automatically bring the cleaning brush and the carrying arm at the starting position of the latter. In one embodiment, this disc record cleaning mechanism includes a mount, or frame, and an arm; the main structure of each is inexpensively made of a bent rod; the frame adjustable connects to and inside the cover; the frame has a transverse loop and upward portion forming transverse and vertical guides for the arm; a weight is attached to the arm to pull it to the starting position; and a counterweight is adjustable along the arm to adjust the pressure on the brush which is clamped to the arm. In another embodiment, the effective weight is provided by the arm, the cleaning brush and associated parts which bodily pivot toward the starting position of the arm upon opening of the cover.</p> |
