Abstract: 354,672. Sockets. STOCK & CO' SPIRALBOHRER - WERKZEUG UN D MASCHINENFABRIK AKT. - GES., R., Marienfelde, Berlin.-(Assignees of Bambach, H. ; 37, Chausseestrasse, Mariendorf, Berlin.) Dec. 22, 1930, No. 38602. Convention date, Dec. 21, 1929. [Class 83 (iii).] A socket 1, particularly for holding a tool-receiving socket 4, has two jaws 6 slid able through a transverse slot 5 in the body 2. The lower limbs of the jaws are hooked at 6b to engage under an end flange 12 on the socket 4 and in a transverse slot 11 therein, whilst the upper limbs 6a are of half the thickness of the limbs 6b so as to be accommodated together in the upper end of the slot 5 as shown in Fig. 3. A spring 7 is located in semicircular recesses in the limbs 6a so as normally to press the jaws together. In operation, the socket 4 is inserted in the bore 3 whilst the chuck is rotating, the end of the flange 12 acting on the rounded ends of the jaws to separate them and allow them to enter an annular recess 10 under the flange, thereby preventing the socket 4 from falling out until rotation causes the jaws to come opposite the slot 11 and snap therein. To release the socket whilst the chuck is rotating, an outer sleeve 8 provided with cam surfaces 8a is moved upwards to cause the jaws to be moved outwards against the spring 7. The upper end of the socket 4 abuts against the surface 13 on the bodv 1 and in modifications the jaws 6 may move in a direction other than perpendicular to the chuck axis or may be pivoted.
