(25) FIG. 6 also shows a stop clamp 33 attached to the stop arm 31 by a dual-purpose stop clamp screw 35, which also functions to enable changes to the distance d between the jaws 32 and 34 through the displacement of the entire stop clamp 33 with respect to the fixed jaw 32 by the user's clock-wise and counter clock-wise rotation of dual-purpose stop clamp screw 35 to allow the jaws 32 and 34 to hold and support a portion of stop rod 29 in a fixed, deform-free condition therebetween.

(26) The adjustability in the distance d between the jaws 32 and 34 also allows for a top-loading of the stop rod 29 to the jaws 32 and 34 and for a top removal of the stop rod 29 from the jaws 32 and 34. Lifting the stop rod 29 upward from the jaws 32 and 34 thereby eliminating the traditional need to slide the stop rod 29 out lengthwise from the jaws 32 and 34 for the removal the stop rod 29 from the jaws the jaws 32 and 34.

(27) It is noted that in alternative embodiments of the present invention the jaws 32 and 34 may each comprises various shape surfaces including but not limited to a flat, zigzag, curved, or slanted surface. In addition, the fixed jaw may comprise a shape similar to a shape of the adjustable jaw or alternative comprise a different shape compared to the shape of the adjustable jaw.

(28) FIG. 6 also shows stop arm 31 including a guide slot 36 for receiving a portion of a protrusion 33a extending from the stop clamp 33 with a portion of the dual-purpose stop clamp screw 35 extending through the protrusion 33a of the stop clamp 33, through the guide slot 36 and into the elongated stop arm 31. In the embodiment of FIG. 6 the protrusion 33a is shown extending from the stop clamp 33 perpendicular to the adjustable jaw 34. Although the dual-purpose stop clamp screw 35 may, in alternative embodiments of the present invention, extend into the stop arm 31 in various directions with respect to the length of the stop arm 31, FIG. 6 shows the dual-purpose clamp screw 35 extending into the stop arm 31 in a direction parallel to the length of the stop arm 31.

(29) FIG. 7 is a perspective view showing an alternative embodiment of a stop device 37 for the positioning a work material held by a machine vise of the present invention. As shown, stop device 37 comprises similar general components to the stop device 10 of FIGS. 1-4. However, stop device 37 further includes a pair of mounting plates 38 extending from a second end 39a of an elongated stop arm 39 of stop device 37, a conical shaped a swivel pin 43 having an exterior surface 43a and a swivel head 40 having a first concave-shaped side 40a conforming to the shape of the exterior surface 43a of conical shaped a swivel pin 43 and a second side 40b.

(30) FIG. 8 is a blow-apart perspective view showing of the stop device 37 of FIG. 7. The concave-shaped side 40a of the swivel head 40 is shown engageable to the exterior surface 43a of swivel pin 43 which is supported and secured between a pair of corresponding orifices 42 located on the pair of mounting plates 38.
