The invention will hereinafter be described more par~icularly with reference to the accompanying drawings which illustrate, by way of example only, a preferred embodiment.
In the drawings, Figure 1 is a perspective view of a vice constructed in accordance with the invention, Figure 2 is a side elevation of the vice, Figure 3 is a plan view, and Figure 4 is a perspective view of a jaw block to which has been attached a gripping surface;
Figure 5 is a plan view, and Figure 6 is a cross-sectional view of the jaw block.
Referring to the drawings, the vice comprises a stock 1 ln which is movable a slide 2. The stock 1 contains a screw threaded housing 3 integral with a base 4 shaped to fit into a prepared recess in the stock 1. The recess is wholly occupied by the base 4, which is thereby secured in position in the recess.
Extending through and supporting the slide 2 is a rod S.
The rod 5 has a screw threaded section which is located in the screw ' 20 threaded housing 3. Upon rotation of the handle 6, the rod 5 movesaxially within the housing 3, and in conse~uence also moves the slide 2. When the vice is in use, the stock 1 is bolted to a support (not shown) by means of bolts (not shown) which pass through bolt apertures 27in a flange 28.
....
Supporting columns la and 2a are provided ~respectively) on the stock 1 and slide 2 and on the columns la and 2a are supported jaw blocks 7 and ~ respectively.

The jaw blocks 7 and 8 each have four jaws 9s 10, 11 and 12 of different construction. Each of the jaw blocks 7 and 8 has a r?cess 13 into which the top of the column la and 2a is adapted to fit snugly. When in position on the top of the column la or 2a, the : 5 jaw block 7 or 8 is held in position thereon by a single retaining pin 14, the shank of which passes through an aperture 15 in the jaw block 7 or 8 and into a socket in the column la or 2a. Thus the jaw block 7 or 8 may easily be turned to any one of four orientations and then maintained in that orientation, simply by removing the retaining pin 14, raising the jaw block 7 or 8 off the top of the column la or 2a, turning the jaw block 7 or 8, replac;ng the jaw block 7 or 8 on the top of the column la or 2a, and inserting the retaining pin 14 : through the jaw block 7 or 8 and into the column la or 2a.
Each of the jaw blocks 7 and 8 has in one gripping surface a pair of screws 17. When not in use, the screws 17 are screwed into the jaw block 7 so that the heads of the screws are below the level of the gripping surface 10, and do not obstruct the gripping surface 10. The screws 17 may also be located so that the heads and shank portions (which are not threaded), lie outside the gripping surface 12.
The shank portions may then by utilised to support a gripping plate 18 which has keyhole shape apertures 19 by means of which the ~ gripping plate 18 may be supported against the gripping surface 10.
