Abstract
Vice-type clamping apparatus has first and second jaw members (11, 12) mounted in spaced longitudinal relation on an elongate support (10) and with the jaws opposed. The first jaw member (11) is pivoted at or near to its lower end to the support (10) and is connected at its upper end through readily-releasable, pedal-operated actuating means (18, 20, 22, 23). The second jaw member (12) is constrained to be movable longitudinally of said support (10). The actuating means is in the form of a linkage and lever arrangement (18, 20) connected to a foot pedal (22) so that downward movement of the foot pedal (22) pivots the first jaw member (11) towards the second jaw member (12) made fast with the support (10) thereby to clamp a workpiece therebetween with the first jaw member (11) being lockable in its clamping position.
Description
- This invention relates to clamping apparatus in the nature of a vice.
- Vice type clamping apparatus have been in use for some time. However, have suffered from the disadvantage that either one clamping apparatus requires to be securely fixed to a work bench or the like and the workpiece.secured therein to enable both hands to be free to work on the workpiece, or the clamping apparatus is hand held receiving only the free hand to be available to work on the workpiece.
- It is an object of the present invention to obviate or mitigate this disadvantage.
- According to a first aspect of the present invention, there is provided a clamping apparatus having a pair of clamping jaws mounted in spaced longitudinal relation on an elongate support, one of said jaws being adjustably movable longitudinally along the support and the other being pivotally connected to the support and pivotal towards and away from the adjustably movable jaw member by ready releasable pedal operated by actuating means which when the jaw is pivoted towards the longitudinally movable jaw can retain said pivoted jaw in said pivoted position.
- According to a second aspect of the present invention, there is provided a clamping apparatus having first and second jaw members mounted in spaced longitudinal relation on an elongate support and with the jaws opposed, the jaw members being constrained to be movable longitudinally of said support, the first jaw member being pivoted at or near to its lower end to the support and being connected at its upper end through actuating means in the form of a linkage and lever arrangement to a foot pedal whose upper end is pivoted to said support, so that downward movement of the foot pedal pivots the first jaw member towards the second jaw member made fast with the support thereby to clamp a workpiece therebetween with the first jaw member being lockable in its clamping position.
- Preferably, the second jaw member can be made fast with the support in one of several positions longitudinally thereof.
- . Preferably also, the support comprises two laterally- spaced channel beams opening inwardly towards each other and spaced apart for movement of the law members therebetween.
- Preferably further, the second jaw member has two pairs of axially opposed stub rods extending laterally from opposite lateral sides thereof and lying in vertically spaced planes passing through said axis, said rods constraining movement of said second jaw member on said support with one pair of rods being located above the beams and the other pair of rods being located below the beams in a manner which permits longitudinal and attitudinal movement of the second jaw member relative to the support whereby in one position, the second jaw member is made fast with the support and in all other positions, the second jaw member is free to move along or arcuately of the support. A bar is provided on the inner face of the second jaw member with its axis in the same plane as the upper pair of stub rods, the bar extending laterally beyond opposed lateral sides of the jaw member and serving to restrict the amount of attitudinal movement.
- An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
- Fig. 1 is a perspective view of a clamping apparatus according to the prevent invention, showing an elongate support, legs for said support, first and second jaw members on said support, and a foot pedal connected through actuating means in the form of a linkage and lever arrangement to said first jaw member;
- Fig. 2 is a side elevation with the support and legs shown in broken line; and
- Figs. 3 and 4 are both side elevations to a larger scale with the first and second jaw members in non- clamping and clamping positions respectively, the support in each case being shown in broken line.
- The
elongate support 10 comprises two laterally- spacedchannel beams beams second jaw members beams plates 13 and adjacent thereto byplates 14,plates beams legs 15 can be secured bybolts 16 as shown. - The first and
second jaw members jaws beams support 10. The first jaw member is pivoted at 17 near its lower end to thesupport 10, the pivot being parallel to the upper and lower limbs of thebeams link 18, extending away from the second jaw member, is pivotally connected at 18A, the other end of saidlink 18 being pivotally connected at 19 to the upper end of acranked lever 20 pivoted at 21 to thesupport 10, the pivot being . parallel topivot 17. The lower end of thelever 20 is bifurcated and afoot pedal 22 unites the outer end of the bifurcated limbs. Aspring 23 is anchored between thesupport 10 adjacent to thepertaining plate 13 and thefirst jaw member 11 rearwardly of thejaw 11A. Thisspring 23 holds thefirst jaw member 11 in a rest position and assists in returning thefirst jaw member 11 to its rest position. Thelink 18,lever 20,foot pedal 22 andspring 23 constitute readily-releasable pedal operated actuating means. Thesecond jaw member 12 has two pairs of axiallyspaces tub rods rods rods 24 being located above the beams and the other pair ofrods 25 being located below the beams. The distance between vertical spaced planes is slightly greater than the depth of the beams. Verticals through the axes ofrods rods 24 being more remote from thefirst jaw member 11 than is the axes ofrods 25. There is therefore a tendency under gravitational forces for the second jaw to pivot aboutrods 24 towards the first jaw. Abar 26 is provided on the inner face of thesecond jaw member 12 with its axis in the same plane as the upper pair ofstub rods 24, thebar 26 extending laterally beyond opposed lateral sides of thejaw member 12 and serving to restrict the amount of attitudinal movement thereof relative to thesupport 10. If pressure is applied to thesecond jaw member 12 in a direction away from thefirst jaw member 11, the second jaw member through interaction between therods beams support 10. In all other positions of the second jaw member, the second jaw member can be moved freely along the support. - In use, for a
workpiece 30 to be clamped between the first and second jaw members, one side of the "workpiece 30 is placed next to thejaw 11A of thefirst jaw member 11 and the second jaw member 1'2 is moved towards the workpiece to abut its opposite side by pressure on the foot pedal, thelever 20 moves about itspivot 21 to movelink 18 to push thefirst jaw member 11 and workpiece against thesecond jaw member 12 to make it fast with thesupport 10. The foot pedal is clamped in position by thepivot 19 being moved from a position in which its axis lies below a line drawn between the axes ofpivots spring 23. Upward movement of the foot pedal readily releases this clamping position and thefirst jaw member 11 returns to its rest position under gravitational forces and influence of thespring 23, and theworkpiece 30 can then be removed. - In a modification, the
rods bar 26 can be dispensed with and instead the second jaw member can track thebeams second jaw member 12 at any desired position on said support. - In a further modification the support may be mountable on a table or work bench.
- A table extension may be provided to attach to one or other side of the support.
- In a modification, the actuating means is a hydraulic or pneumatic ram operable by a foot pedal.
- In a further modification the two beams are replaced by a single beam and the lower end of the second jaw is formed as an eye and threaded on to the beam. The
stub rods bar 26 being omitted in this modification. If necessary a longitudinal groove can be provided along one or both lateral sides of the beam.
