Description
The invention relates to vices and is partic-ularly although not necessarily exclusively concerned with bench-mounted vices of the handy-man type~
Particularly in the DIY field it is not usual for a user to purchase more than one vice to allow for those occasions where an abnormally wide workpiece needs to be gripped. Thus, when a conventional vice is being used with a jaw opening of for example three to four inches maximum, -the user experiences great difficulty in gripping e.g. planks of more than four inch width.
The objec-t of the present invention is to pro-vide a vice capable of accomodating workpieces of greater width than the normal jaw opening of the vice, in rela-tively simple and cost-effective manner.
According to -the present invention, there is provided a vice comprising a body portion on which are provided two fixed jaws located at different distances from opposite ends of the body portion, a movable jaw mounted on at least one slide extending through a plain hole in the body portion and with a drive screw rotatably secured to the movable jaw and extending through a thread-ed hole in the body portion, wherein said movable jaw is mountable on the body portion in a first position to co-operate with one fixed jaw and be movable towards and away from said one fixed jaw, and in a second position where the at least one slide and drive screw extend in the opposite direction through the respective plain and threaded holes in the body portion, and whereby the mova-ble jaw co-operates with and is movable towards and away from the second fixed jaw and whereby two ranges of jaw openings are provided.
Preferably, with -the vice being of the bench-mounted type, the body portion may be rotatably secured to a mounting plate adapted to be secured to a work sur-~6~3~7 face, with locking means provided to hold the body portionat a required disposition on the mounting plate. Thus, during normal use the vice can be used in a conventional manner to hold workpieces of widths up to the maximum jaw opening provided. When a wider workpiece is to be held, the movable jaw can simply be unscrewed completely from the body member, the locking means released, the body portion rotated through 180 , the locking means re-applied, and the movable jaw relocated on the body portion such /
:' :
~569(~
that the movable jaw face co-operates with the further fixed jaw on the body.
Preferably, the vice is provided with two ranges of opening, one up to, e.g., 3.~", and the other 3.~"
minimum to 7" maximum.
Preferably, with this embodiment the rotatable mounting of the body portion on the mounting plate can simply be effected by providing a mounting plate with a circular opening which opening is recessed\on its under-side, to loca-te a rotatable locking plate when the mount-ing plate is secured to a work surface. Thus with at least one upstanding threaded stem on the rotatable plate passing through a hole in the body portion of the vîce to be engaged by a threaded locking member, the locking member can be released to allow rotation of the body and the threaded locking member re-tightened when the body member is in the required alternative position.
Preferably, the body portion may be secured to a work surface by e.g. a G-clamp, one leg of which passes through a plain hole in the body portion. In this case, the body portion can be reversed by simply releasing and removing the G-clamp, turning the body through 180 and replacing and retightening the G-clamp, so that with the movable jaw relocated on the body portion the wider range of jaw opening is provided, in exceedingly simple manner.
Preferably, the G-clamp may be of plate con-struction, when the top plate of the clamp may be con-structed in the same manner as the mounting plate of a bench-mounted vice, to enable release and xotation of the vice body as and when required.
Thus, a further advantage of the invention in its forms where the vice body is rotatably mounted on a mounting plate or the top plate of a G-clamp of plate construction is that the vice can be used after the manner ~2~913'7 of a conventional swivel-bodied vice with either of the ranges of vice opening in use.
Preferably, the firs-t fixed jaw may be provided by an upstanding projection from the body portion, when the second fi.xed jaw can be formed by the rearward face of the projection.
Preferably, to enable the vice to yrip a variety of workpieces in either of its operative positions the operative face of either or both of the first and second fixed jaws may be provided with reversible or replacable jaw .

Figure 5 corresponds to Figure 1 but shows the ~ice in its second operating condition;
Figure 6 corresponds to Figure 1 but shows a second embodiment of vice according to the invention; and Figure 7 corresponds to Figure 6 but shows the vice in its second operating condition.
In Figures 1 to 5, a vice comprises a body 1 having an upstanding fixed jaw member

Two embodiments of the invention will now be described with reference to the accompanying drawings, in which:
Figure 1 is a side elevation of one embodiment of vice according to the invention;
Figure 2 is a plan view of Figure 1;
Figure 3 is a front elevation of Figure 1;
Figure 4 is a section on the line 4-4 of Figure 2;
Figure 5 corresponds to Figure 1 but shows the ~ice in its second operating condition;
Figure 6 corresponds to Figure 1 but shows a second embodiment of vice according to the invention; and Figure 7 corresponds to Figure 6 but shows the vice in its second operating condition.
In Figures 1 to 5, a vice comprises a body 1 having an upstanding fixed jaw member
2. As shown particularly by Figure 4, the body 1 has two plain through holes 3 and a threaded hole 4, all on parallel axes. The vice has a movble jaw 5 provided with two -6- ~5~ 7 fixed slide rods 6 slidably mounted in the plain holes 3, and a rotatably mounted drive scre~ 7 engaging in the threaded hole 4, the àrive screw extending through the movable jaw to an operating handle 8.
The vice body 1 has an integral base plate 9 located on an a~nular mounting plate 10. As shown by Figure 4, the annular mounting plate is recessed at 11, and in the recess is located a rotatable locking plate 12 provided with two upstanding threaded stems 13 which pass through corresponding holes in the base plate 9 to be engaged by respective lock nuts 14.
The annular mounting plate is located on the top plate 15 of a generally plate~like G-clamp 16, and there secured by four screws 17, a pad 18 of resilient friction material being provided on the undersurface of the top plate 15 of the G-clamp, to assist retention of the G-clamp and hence the vice on a surface 19 to which the clamp is secured.
Thus, in the operating condition illustrated in Figure 1, where the upstanding jaw member 2 is at the end of the body 1 of closest approach to the movable jaw, the jaw ~56~
face 20 of the movable ja~; 5 can be closed on to the jaw face 21 of the fixed jaw. Thus, a relatively conventional handy-man viceja~
opening of say 0 to 3 inches is provided.
~]owever, for those occasions where a ~ider jaw opening is requirèd, it is simply the case of removing the movable j~w 5 from the body 1 9 releasing the lock nuts 14 and rotating the body 1 through 180, the lock nuts re-ti~htened, and the movable jaw relocated on the body, with the slide bars and the operatins screw passing oppositely through the body. This condition is illustrated in Figure 5, from which it can be seen that the upstanding jaw memberis now at the end of the body remote from the movable jaw, so that a second jaw face 22 can co-operate with the jaw face 20 on the movable jaw to provide a second range of jaw openinss say from 3 inches to 6 inches.
In the second embodiment of vice according to the invention illustrated in Figures 6 and 7, an alternative manner of locating the vice on a surface is illustrated, in an otherwise identical vice construction.
In this embodiment, a bench~mounted ,~
56~3Q~7 vice is provided, the integral base plate 9 being located on an annular mounting plate 10 adapted for relatively permanent securing to a support surface 19, by having four screw holes (not shown) at its corners~ through which screws extend, the screws passing through corresponding holes f~rmed in the support surface.
It will be appreciated that the vice of the invention in either of its embodiments illustrated, in each of its operating conditions, has the additional advantage of serving as a rotatable vice, it simply being a matter of releasing the lock nuts 14 and rotating the body 1 to any desired angular disposition~ and re-tightening the lock nuts.
The vice body 1 has an integral base plate 9 located on an a~nular mounting plate 10. As shown by Figure 4, the annular mounting plate is recessed at 11, and in the recess is located a rotatable locking plate 12 provided with two upstanding threaded stems 13 which pass through corresponding holes in the base plate 9 to be engaged by respective lock nuts 14.
The annular mounting plate is located on the top plate 15 of a generally plate~like G-clamp 16, and there secured by four screws 17, a pad 18 of resilient friction material being provided on the undersurface of the top plate 15 of the G-clamp, to assist retention of the G-clamp and hence the vice on a surface 19 to which the clamp is secured.
Thus, in the operating condition illustrated in Figure 1, where the upstanding jaw member 2 is at the end of the body 1 of closest approach to the movable jaw, the jaw ~56~
face 20 of the movable ja~; 5 can be closed on to the jaw face 21 of the fixed jaw. Thus, a relatively conventional handy-man viceja~
opening of say 0 to 3 inches is provided.
~]owever, for those occasions where a ~ider jaw opening is requirèd, it is simply the case of removing the movable j~w 5 from the body 1 9 releasing the lock nuts 14 and rotating the body 1 through 180, the lock nuts re-ti~htened, and the movable jaw relocated on the body, with the slide bars and the operatins screw passing oppositely through the body. This condition is illustrated in Figure 5, from which it can be seen that the upstanding jaw memberis now at the end of the body remote from the movable jaw, so that a second jaw face 22 can co-operate with the jaw face 20 on the movable jaw to provide a second range of jaw openinss say from 3 inches to 6 inches.
In the second embodiment of vice according to the invention illustrated in Figures 6 and 7, an alternative manner of locating the vice on a surface is illustrated, in an otherwise identical vice construction.
In this embodiment, a bench~mounted ,~
56~3Q~7 vice is provided, the integral base plate 9 being located on an annular mounting plate 10 adapted for relatively permanent securing to a support surface 19, by having four screw holes (not shown) at its corners~ through which screws extend, the screws passing through corresponding holes f~rmed in the support surface.
It will be appreciated that the vice of the invention in either of its embodiments illustrated, in each of its operating conditions, has the additional advantage of serving as a rotatable vice, it simply being a matter of releasing the lock nuts 14 and rotating the body 1 to any desired angular disposition~ and re-tightening the lock nuts.
