Abstract: 429,535. Loft - ladders. SUTHERLAND, W. G., 18, North Portland Street, Glasgow. March 10, 1934, No. 7680. [Class 20 (ii)] An extensible loft-ladder unit comprises an upper ladder section 1 having its upper end slidably mounted in an upright guide frame 3, a lower ladder section 2 slidably mounted on the section 1, means which automatically lock the section 1, when fully raised, to the guide frame and release it when the section 2 is fully lowered, and means which automatically lock the sections together when extended and unlock them when the upper section is locked to the guide frame. The sections are counterbalanced by weights 6, 7, housed in the guide frame. In the construction shown, ropes 10 pass around pulleys 13 on the weight 6, over pulleys 12, 14, on the guide frame, and are connected at one end to the weight 7 and at the other end to the section 2. When the sections are raised as shown in Figs. 1 and 2 the weight 6 rests on the base of the frame 3. In the lowering operation the section 2 first descends and is counterbalanced by the weight 7 until projections 15 on the section encounter the weight; thereafter both sections and the weight 7 descend together and are counterbalanced by the weight 6. The upper section is locked to the guide frame by a spring- controlled bar 16 which engages in notches 19 formed in cam plates 17 attached to the foot of the section. Unlocking is effected during the lowering operation by a striker bar 20 on the section 2 which is adapted to engage with and depress the bar 16. The bar 16 also acts as a stop for a pair of spring-controlled latches 21. These latches are mounted on a spindle 22 which carries an arm 23 adapted to engage with the bar 16. When the bar is depressed, the latches are urged by their springs into locking engagement with catches 24 on the section 2, and at the same time shoulders 25 on the plates 17 are engaged by a crossbar 26 on the section 2. The sections are thus interlocked and can be raised or lowered together.
