[Class 146 (ii).] In wall blackboards of the type in which one or more boards A are mounted in fittings on the wall and are removable, reversible, and adjustable therein, the board or boards are supported in position by means of two horizontal rails BI, B<2>, the head rail B<1> being provided with suitable means to engage the upper edge of the board or boards to prevent them from falling forwards, and the sill rail B<2> with a front strip b<2> behind which the lower edge of the board or boards are situated. The upper edge of the board A engages behind a strip b or in spring clips made fast to the rail B<1>, there being sufficient vertical space to permit the board to be lifted out of engagement with the strip b<2>, after which it can be drawn forward for removal or reversal. Springs b<3> to prevent rattling and hooks C for maps or the like are mounted on the rail B<1>, and the strip b<2> is hollowed at b' to hold chalk &c. More than one board may be mounted side by side between the rails, and instead of the long strips b<1>, b<2> separate short strips or blocks may be provided. Blocks may be provided on the sill rail B<2> to limit the longitudinal movement of the boards.
