Abstract

1369208 Tap-holders BISHOP EAVES & SONS Ltd 13 Oct 1971 [13 Oct 1970] 48474/70 Heading B3N A chuck includes a tool holding unit 12 and a body 11 having means whereby it can be driven by a driving element 10 and can telescope relative thereto, the driving element is a shank which has a sliding key 16 connection within the body and the shank telescopes relative to the body under the action of a biasing means, spring 26 housed entirely within an axial bore 25 in the shank and means for transmitting drive to the tool holding unit includes a compound slide unit 17 comprising a plurality of interfitting units, 18, 19 and 20 having tongue and groove driving connections and arranged in such a way as to permit limited radial movement of the tool holding unit relative to the driving shank in a pair of mutually transverse directions. Body 11 drives unit 19 via a pin 21. Units 19 and 18 are kept aligned by a ball and a spring 49. Unit 18 is in driving connection with holding unit 12 by a pin 36. The holding unit accepts an adapter as shown in Fig. 6 or Fig. 2. Each adapter is gripped by balls 41, the position of which is controlled by a spring biased sleeve 39; driving connection is by lugs 54 engaging in gaps in the adapters. A tap is driven via bore 56 and gripped by balls 59. The adapter of Fig. 2 is an overload clutch wherein at a predetermined torque plunger 66 is forced against the loading of Belleville washers 72.
