The inward movement of the plate lO-causes an inwardmovement of the extension 12 and the latter 13 pickup the rod 20causes an inward movementof the rod 20 and of the curved 'plate18which is'connected to the rod 20 by the spring 21. The curved plate 18 moves gradually in contact with the rod or the inclined plate 10 andthen abuts against and *moves inwardly the curved plate 18. It will befseen that" the device permits or the use of comparatively light springs, and opsmooth checking action on the door when the latter is beingclosed.
