Description
BACKGR~UND OF THE INVENTION
Field of the Invention This invention relates to devices for supporting workpieces. The invention relates more particularly to an S improved auxiliary support means for extending the usefulness of such devices.
Description of the Prior ~rt Workpiece support devices are known for gripping and supporting a workpiece during working operations A device of this type generally comprises a vise having a pair of jaw members and a means for adjusting the spacing between the jaw members for gripping and releasing the workpiece. The size of a work-piece which can be gripped by the device is limited principally by the maximum spacing between gripping faces of the jaw members when the jaws are adjusted to a maximum opening. The gripping spacing for a workpiece has been increased by the use of demountable, auxiliary support bodies, referred to as swivel pegs, ~hich are mounted to the gripping members and which are adapted to receive and engage a workpiece. A swivel peg includes a mounting seg~ent which is positioned in an aperture of the g~ipping ~ember and is supported on a surface of the member.
The auxiliary support body is adapted to engage an edge of a workpiece while a similar swivel peg on another gripping member of the de~ice similarly engages and grips another edge of the workpiece. Since the swivel bodies are set back from the jaw faces of the gripping member, they thereby effectively provide an enla~ged ;aw opening for gripping workpieces larger than the spacing between the jaw members can accommodate.
An improved form of portable vise for supporting a workpiece during relatively moderate to light working operations9 which i5 of relatively light weight and which can be fabricated relatively economically is described in a related case which is assigned to the assignee of this invention. In that workpiece support arrangement the jaw members are formed by elongated bodies each having a firs~ jaw gripping surface which engages a workpiece, a second generally planar surface extending trans-versely from the first surface, and a third surface extending at an angle from the second surface. The latter surface which is beveled with respect to the second surface facilitates positioning of work tools in close proximity to the workpiece being supported. It is generally desirable to position the auxiliary support body on a relatively flat surface and ~his jaw me~ber configuration provides a flat, second surface of relatively limited width (w) on which an auxiliary support body can be mounted. In prior arrangements, the width of the jaw member is relatively large, and, known, rotatably mounted, auxiliary support bodies have presented a workpiece gripping surface which is positioned between the jaw opening and the rotatable mounting location of ~he auxiliary support body.
However, rotatable mounting of an auxiliary support body in the sa~e manner on the flat surface of relatively limited width of the aforementioned jaw member will, while advantageously in-creasing the effective jaw opening device, provide a substanti-ally lesser increase in jaw opening than is desired.
The workpiece support device as disclosed in the afore~entioned related case is economically fabricated principally of plastic elastomer materials and the fabrication tolerances are accordingly not rigid. While this ~orkpiece support de~ice has provided satisfactory operation~ the application of a substantial gripping force to the workpiece tkrough the auxiliary support bodies has caused a slight de-flection of these bodies and contact between the gripped

An improved form of portable vise for supporting a workpiece during relatively moderate to light working operations9 which i5 of relatively light weight and which can be fabricated relatively economically is described in a related case which is assigned to the assignee of this invention. In that workpiece support arrangement the jaw members are formed by elongated bodies each having a firs~ jaw gripping surface which engages a workpiece, a second generally planar surface extending trans-versely from the first surface, and a third surface extending at an angle from the second surface.

workpiece and the support body is reduced. This factor, inaddition to the relatively smooth surface of the plastic elastomer support body reduces the gripping characteristics of the support bod~ and, at times, a gripped workpiece will escape the grip of the auxiliary bodies.
It would be advantageous to provide a means for increasing the effective jaw opening of the aforementioned workpiece gripping device and to enhance the gripping characteristics of the workpiece auxiliary support bodies.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION
Referring now to the drawing and particularly to Fig. 19 the ~ise 16 is shown supported on a surface 17 of a workbench or a support table. The vise 16 includes first and sPcond ~ . .
workpiece gripping jaw members 18 and 20 and a means for supporting these members. The vise support means comprises a support body 22 and a base body 24. The support body comprises an integrally formed frame member 26 and an integrally formed bowl shaped member 28. A means including manually rotatable crank arms, one of which is referred to in ~igure 1 by reference numeral 30, is provided for varying spacing between the jaw members 18 and 20 in order to grip and release a workpiece. The vise 16 and the means for varying the spacing between the jaw members 18 and 20 is disclosed in greater detail in the aforementioned related case.
The jaw member 18 is elongated and includes a first surface 32 providing a workpiece gripping face extending in a plane 34, as illustrated in Fig. 1 and which plane is perpendicular to the drawing and extends out of the paper as viewed in Fig. 1. The jaw member 18 further includes a second5 generally planar surface 36 which extends transversely to the surface 32 and the plane 34 and which has a relatively narrow width(w). ~ third surface 38 extends transversly at an angle from the surface 36. This bevel is provided in order to facili-tate the positioning of work tools adjacent to a supported workpiece 40. The surface 36 has a relatively narrow width (w) with respect to the overall width of the jaw member 18. In an exemplary arrangement which is not deemed limiting in any respect, the jaw member 18 has a to~al width measured between the surface 36 and a fourth surface ~2 of about 2 inches while the surface 36 has a width (w) of about 3/4 of an inch. The jaw member 20 is similarly construc~ed.
The maximum spacing which can be achieved between ~he surface 32 of jaw member 18 and a similar surface 4~ of jaw member 20 when the jaws are adjusted to a maximum opening ~3 is indicated by the distance (m). In order to increase the effective maximum spacing between the jaw members, first and second auxiliary support bodies 46 and 48 are provided and are demountably supported on the jaw members 18 and 20 respectively.
S As illustrated in Fig. 1, the support bodies 46 and ~8 are adapted to grip and engage the workpiece 40 which has a dimension greater than the maximum spacing (m). It can also be seen from Fig. 1 that the workpiece 40 has a dimension which extends beyond the relatively flat surface segment 36 of jaw m-ember 18 and beyond a similar relati~ely flat surface segment 50 of the jaw member 20.
Referring now to Fig. 3, the auxiliary support body 46 is sh~wn in greater detail. Wbile the following discussion describes the support body 46, and the jaw member 18, it will ~5 be understood that the description also applies to the support body 48 and its mounting to jaw member 20 as well as to other auxiliary support bodies which can be mounted to the jaw members 18 and 20. The support body 46 comprises a first, elongated, generally cylindrically shaped-mounting segment 52 having a longitudinal a~is 54. This se-gment is positioned in a keyhole shaped aperture which is formed in the jaw member and extends from the flat surface 36 parallel to the plane 34 and the axis 54. A tab .or foot 56 extends from a distal part of the segment 52 and engages a lower surface 59 of the jaw member for inhibi-tipg motion of the body 46 in the direction of ~he longitudinalaxis.54. This a.rrangement is described in greater detail in a further related case which is assigned to the assignee of this invention. The auxiliary support body 46 includes a second int~grally formed, parallelpiped shaped segment 58 which extends transversely to the mounting segment 52 and has a relatively flat surface 60 which rece.ives and supports the workpiece 40.
2~
Support body 46 also includes a third buttress segment 62 which is positioned at a distal location of the second segment 58 and includes a workpiece gripping surface 64. The gripping surface 64 extends transversely to the surface 60 and preferably 5 normal to this surface and, with the orientation on the jaw member shown in Fig. 3, preferably parallel to the plane 34 of the gripping surface 32. Body 46 i3 rotatably mounted to jaw member 18 and, upon gripping irregular shaped workpieces, the surface 64 may be orientated non-parallel to the plane 54.
A body 66 which is described in greater detail hereinafter is mounted adjacent the surface 64. The workpiece 40 is positioned adjacent a workpiece gripping surface 68 of the support body 48 and adjacen~ similar gripping surfaces of auxiliary support bodies, for gripping the workpiece therebetween. Gripping is effected by. supporting the workpiece 40 on the flat surface S0 and rotating the vise .c~ack arms to.establish gripping con~act between the support bodies and workpiece.
It will be observed from Figs. 1 and 3 that the gripping face 64 is positioned at a location beyond the width (w) of the relatively flat surface segment 36 and is positioned above the beveled surface 38. The auxiliary support body ~ thus provides for positioning of a workpiece gripping surface at a location spaced transversely beyond the mounting position indica~ed by the axis 54 by a distance tL). Axis 54 is spaced transversely from the jaw face 32 by the distance (1) and the effective jaw opening is increased by the distance 2 ~ L). The described arrangement thus advantageously provides for effectively in-creasing the Jaw opening in a device having a relatively narrow width (w) jaw surface and which increase is greater than the width (w) of the surface.
In addition to the gripping surface 64 provided by the ~.' ,~ ,i buttress segment 62, the second integrally formed, parallelpiped shaped segment 58 includes a surface 69 which provides a gripping surface for a workpiece. The u~e of the surface 69 in gripping a workpiece is illustrated in Fig. 2. The surface 69 which ex-5 tends parallel to the jaw face 32 is positioned intermediatethe jaw face and the mounting location indicated by the axis 54 whereas the surface 64 is positioned outwardly from the mounting locatio~. Similar to surface 64, the body 46 may be rotated and the surface 69 may be positioned in a non-parallel orientation with respect to plane 54 when gripping an irregular shaped workpiece. Auxiliary support body 46 thus prov;des two alternative gripping surfaces 64 and 69 which are used in con-junction with similar gripying surfaces of an auxiliary body on jaw member 20 to provide two separate, effectively enlarged jaw openings for the workpiece support device 16.
Body 66 which is illustrated in greater detail in Figo 4 increases frictional engagement between the workpiece and the surface ~4. The gripping surface 64 of the support body 62 is formed af a smooth material such as a polymer plastic and in order to reduce undesired escape of a workpiece from the grip of a pair of auxiliary support bodies, the body 66 is provided and is mounted adjacent the surface 64. Body 66 is formed of a material for enhancing gripping as for example, a resilient material or an abrasiYe material. When a resilient material îs used, the workpiece contacts the body 66 and this body is slightly deformed thereby ~ffectively providing a gripping surface which assumes the configuration of the workpiece.
Frictional engagement between the workpiece and the gripping surface 64 is thus enhanced. The body 64 can be formed of various materials which operate .o increase the frictional engagemen~ between the surface 64 and the workpiece.
_9_ ~6~PZ~7 A preferred material is a resilient material as for example a resilient material such as rubber~ Other nonresilient, nonslip materials can also be provided, as for example, a body o~ an abrasive ~aterial such as sandpaper which is supported adjacent the surface 64. The body 64 is also supported adjacent surface 69 for similarly inhibiting escape of a workpiece which is gripped by this surface. In Fig. 4, the body 64 is formed of a rubber and is shown to include an integral se~ment 70 which conforms with and engages a cutout 72 formed in the auxiliary support body 62. The cutout is also illustrated in Fig. 5 with the body 66 demoun~ed. Alternatively, as illustrated in Fig. 6, an alternative body 74 for increasing the friction is mounted adjacent the gripping surface 64 by an adhesive 76.
An improved arrangement of a workpiece support device and auxiliary support bodies has thus been described. The arrangement provides for effectively increasing the jaw opening of the deYice when the device includes a jaw me~ber having a planar body of relatively narrow width. The auxiliary support device provides a gripping surface whi&h is spaced transversely from the mounting location of the auxiliary body. The auxili-ary body is further advantageous in that the body provides two gripping surfaces which provide two differing, enlarged jaw openings. ~ means is also provided in the form of a body mounted adjacent to gripping surfaces of the auxiliary support body for increasing the frictional contact with the ~ripped body and inhibiting escape of a gripped work body.
While there have been described particular embodiments of the inventlon, it will become apparent to those skilled in the art that varia~ions may ~e ~ade thereto withou~ departing from the spirit of the invention and ~he scope of the appended cla-ims.

workpiece and the support body is reduced. This factor, inaddition to the relatively smooth surface of the plastic elastomer support body reduces the gripping characteristics of the support bod~ and, at times, a gripped workpiece will escape the grip of the auxiliary bodies.
It would be advantageous to provide a means for increasing the effective jaw opening of the aforementioned workpiece gripping device and to enhance the gripping characteristics of the workpiece auxiliary support bodies.

Accordingly, it is an object of this invention to provide an improved arrangement of a workpiece gripping device and auxiliary support bodies.

DETAILED DESCRIPTION
Referring now to the drawing and particularly to Fig. 19 the ~ise 16 is shown supported on a surface 17 of a workbench or a support table. The vise 16 includes first and sPcond ~ . .
workpiece gripping jaw members 18 and 20 and a means for supporting these members. The vise support means comprises a support body 22 and a base body 24. The support body comprises an integrally formed frame member 26 and an integrally formed bowl shaped member 28. A means including manually rotatable crank arms, one of which is referred to in ~igure 1 by reference numeral 30, is provided for varying spacing between the jaw members 18 and 20 in order to grip and release a workpiece. The vise 16 and the means for varying the spacing between the jaw members 18 and 20 is disclosed in greater detail in the aforementioned related case.
The jaw member 18 is elongated and includes a first surface 32 providing a workpiece gripping face extending in a plane 34, as illustrated in Fig. 1 and which plane is perpendicular to the drawing and extends out of the paper as viewed in Fig. 1. The jaw member 18 further includes a second5 generally planar surface 36 which extends transversely to the surface 32 and the plane 34 and which has a relatively narrow width(w). ~ third surface 38 extends transversly at an angle from the surface 36. This bevel is provided in order to facili-tate the positioning of work tools adjacent to a supported workpiece 40. The surface 36 has a relatively narrow width (w) with respect to the overall width of the jaw member 18. In an exemplary arrangement which is not deemed limiting in any respect, the jaw member 18 has a to~al width measured between the surface 36 and a fourth surface ~2 of about 2 inches while the surface 36 has a width (w) of about 3/4 of an inch. The jaw member 20 is similarly construc~ed.
The maximum spacing which can be achieved between ~he surface 32 of jaw member 18 and a similar surface 4~ of jaw member 20 when the jaws are adjusted to a maximum opening ~3 is indicated by the distance (m). In order to increase the effective maximum spacing between the jaw members, first and second auxiliary support bodies 46 and 48 are provided and are demountably supported on the jaw members 18 and 20 respectively.
S As illustrated in Fig. 1, the support bodies 46 and ~8 are adapted to grip and engage the workpiece 40 which has a dimension greater than the maximum spacing (m). It can also be seen from Fig. 1 that the workpiece 40 has a dimension which extends beyond the relatively flat surface segment 36 of jaw m-ember 18 and beyond a similar relati~ely flat surface segment 50 of the jaw member 20.
Referring now to Fig. 3, the auxiliary support body 46 is sh~wn in greater detail. Wbile the following discussion describes the support body 46, and the jaw member 18, it will ~5 be understood that the description also applies to the support body 48 and its mounting to jaw member 20 as well as to other auxiliary support bodies which can be mounted to the jaw members 18 and 20. The support body 46 comprises a first, elongated, generally cylindrically shaped-mounting segment 52 having a longitudinal a~is 54. This se-gment is positioned in a keyhole shaped aperture which is formed in the jaw member and extends from the flat surface 36 parallel to the plane 34 and the axis 54. A tab .or foot 56 extends from a distal part of the segment 52 and engages a lower surface 59 of the jaw member for inhibi-tipg motion of the body 46 in the direction of ~he longitudinalaxis.54. This a.rrangement is described in greater detail in a further related case which is assigned to the assignee of this invention. The auxiliary support body 46 includes a second int~grally formed, parallelpiped shaped segment 58 which extends transversely to the mounting segment 52 and has a relatively flat surface 60 which rece.ives and supports the workpiece 40.
2~
Support body 46 also includes a third buttress segment 62 which is positioned at a distal location of the second segment 58 and includes a workpiece gripping surface 64. The gripping surface 64 extends transversely to the surface 60 and preferably 5 normal to this surface and, with the orientation on the jaw member shown in Fig. 3, preferably parallel to the plane 34 of the gripping surface 32. Body 46 i3 rotatably mounted to jaw member 18 and, upon gripping irregular shaped workpieces, the surface 64 may be orientated non-parallel to the plane 54.
A body 66 which is described in greater detail hereinafter is mounted adjacent the surface 64. The workpiece 40 is positioned adjacent a workpiece gripping surface 68 of the support body 48 and adjacen~ similar gripping surfaces of auxiliary support bodies, for gripping the workpiece therebetween. Gripping is effected by. supporting the workpiece 40 on the flat surface S0 and rotating the vise .c~ack arms to.establish gripping con~act between the support bodies and workpiece.
It will be observed from Figs. 1 and 3 that the gripping face 64 is positioned at a location beyond the width (w) of the relatively flat surface segment 36 and is positioned above the beveled surface 38. The auxiliary support body ~ thus provides for positioning of a workpiece gripping surface at a location spaced transversely beyond the mounting position indica~ed by the axis 54 by a distance tL). Axis 54 is spaced transversely from the jaw face 32 by the distance (1) and the effective jaw opening is increased by the distance 2 ~ L). The described arrangement thus advantageously provides for effectively in-creasing the Jaw opening in a device having a relatively narrow width (w) jaw surface and which increase is greater than the width (w) of the surface.
In addition to the gripping surface 64 provided by the ~.' ,~ ,i buttress segment 62, the second integrally formed, parallelpiped shaped segment 58 includes a surface 69 which provides a gripping surface for a workpiece. The u~e of the surface 69 in gripping a workpiece is illustrated in Fig. 2. The surface 69 which ex-5 tends parallel to the jaw face 32 is positioned intermediatethe jaw face and the mounting location indicated by the axis 54 whereas the surface 64 is positioned outwardly from the mounting locatio~. Similar to surface 64, the body 46 may be rotated and the surface 69 may be positioned in a non-parallel orientation with respect to plane 54 when gripping an irregular shaped workpiece. Auxiliary support body 46 thus prov;des two alternative gripping surfaces 64 and 69 which are used in con-junction with similar gripying surfaces of an auxiliary body on jaw member 20 to provide two separate, effectively enlarged jaw openings for the workpiece support device 16.
Body 66 which is illustrated in greater detail in Figo 4 increases frictional engagement between the workpiece and the surface ~4. The gripping surface 64 of the support body 62 is formed af a smooth material such as a polymer plastic and in order to reduce undesired escape of a workpiece from the grip of a pair of auxiliary support bodies, the body 66 is provided and is mounted adjacent the surface 64. Body 66 is formed of a material for enhancing gripping as for example, a resilient material or an abrasiYe material. When a resilient material îs used, the workpiece contacts the body 66 and this body is slightly deformed thereby ~ffectively providing a gripping surface which assumes the configuration of the workpiece.
Frictional engagement between the workpiece and the gripping surface 64 is thus enhanced. The body 64 can be formed of various materials which operate .o increase the frictional engagemen~ between the surface 64 and the workpiece.
_9_ ~6~PZ~7 A preferred material is a resilient material as for example a resilient material such as rubber~ Other nonresilient, nonslip materials can also be provided, as for example, a body o~ an abrasive ~aterial such as sandpaper which is supported adjacent the surface 64. The body 64 is also supported adjacent surface 69 for similarly inhibiting escape of a workpiece which is gripped by this surface. In Fig. 4, the body 64 is formed of a rubber and is shown to include an integral se~ment 70 which conforms with and engages a cutout 72 formed in the auxiliary support body 62. The cutout is also illustrated in Fig. 5 with the body 66 demoun~ed. Alternatively, as illustrated in Fig. 6, an alternative body 74 for increasing the friction is mounted adjacent the gripping surface 64 by an adhesive 76.
An improved arrangement of a workpiece support device and auxiliary support bodies has thus been described. The arrangement provides for effectively increasing the jaw opening of the deYice when the device includes a jaw me~ber having a planar body of relatively narrow width. The auxiliary support device provides a gripping surface whi&h is spaced transversely from the mounting location of the auxiliary body. The auxili-ary body is further advantageous in that the body provides two gripping surfaces which provide two differing, enlarged jaw openings. ~ means is also provided in the form of a body mounted adjacent to gripping surfaces of the auxiliary support body for increasing the frictional contact with the ~ripped body and inhibiting escape of a gripped work body.
While there have been described particular embodiments of the inventlon, it will become apparent to those skilled in the art that varia~ions may ~e ~ade thereto withou~ departing from the spirit of the invention and ~he scope of the appended cla-ims.
