Abstract
11,371. Samaia, D. May 7. Spring operation and control.-The stretcherbar 2 of the points is connected by a pin-andslot connexion 7 with a toothed sector 3 pivoted at 4 and engaged by a toothed wheel 8 carried by a spring plunger 10 pivoted at 11. When the wheel 8 is arranged to engage the centre part of the sector, and the points are trailed through or otherwise moved, the spring plunger forces them completely over and retains them in this position. If the wheel is arranged to engage at either end 13 or 14 of the sector, the points always come back to their original set position after being trailed through. Two possible arrangements of the device with respect to the stretcher-bar are shown.
