Definitions
- Said spring abutment may be retained in preferred rotational positions relative to said adjacent part of the torque wrench by means of a resiliently biassed detent, said lock means being selectively operable on said detent either to permit said spring abutment to rotate relative to said adjacent part or to cause said detent mutually to lock said spring abutment and said adjacent part.
- the pawl carrier 120 (separately detailed in Figs. 4 and 5) is formed with two pawl-mounting notches 132 (shown in Figs. 4 and 5 without pawls therein) which are mutually angularly spaced apart by 170°. Since 170° is a integral number of angular separations of the ratchet teeth 130, plus half such an angular separation (81 ⁇ 2 x 20°), one of the two mutually identical pawls 134 (Figs.
- the pawl 534 (Figs. 38 and 39) is correspondingly extended in comparison to the pawl 134 (Figs. 6 and 7).
- the pawl 534 is slightly tapered in profile.
- the internal ratchet teeth 530 (Figs. 34 and 35) formed in the radially inner periphery 528 of the annulus 518 are likewise axially extended to the full axial extent of the annulus 518 as may be seen by comparing Fig. 35 with Fig. 3.
- the teeth 530 have cross-sectional profiles which are the same as those of the teeth 130 as may be noted from the essential identity of Fig. 34 with Fig. 2.
