Abstract

Appareil dans lequel les mâchoires peuvent être retirées en bloc de la tête d'expansion. Le corps 10 de l'appareil, muni du levier 13, comporte un alésage 11 dans lequel glisse un mandrin 12 ayant une extrémité conique 21 et une tête 20 sur laquelle agit la came 17 du levier 16. En descendant, le mandrin 12 écarte les mâchoires 28 dont les portions 29 sont maintenues ensemble par une douille 25. Cette douille, vissée sur le corps 10, comporte un taraudage 24, un décrochement 33, une collerette 26. Les mâchoires 28/29 sont rappelées vers le centre par des ressorts 32, 49 placées dans des gorges annulaires.
