918,309. Preventing rattling of windows. CELWOOD INDUSTRIES Ltd. April 21, 1960 [July 6, 1959], No. 13965/60. Classes 44 and 65 (1). A tensioning device for maintaining the upper portions of the overlapped panes 10, 12 of a sashless sliding window tightly pressed against each other comprises a base 34 having a flat mounting surface and mounting a socket 40 with its axis parallel to the mounting surface, the base having elongated slots 36 for freely receiving screws 38 for adjustment purposes, the socket securely containing the base portion of a truncated cone section 44 terminating in a flat friction tip and having a free length such that when the device is secured in position, siding movement of the pane 12 causes radial deflection of the cone section which is sufficiently resistant to the deflection as to creep back to normal position after deflection against the resistance of the pane 12. |
