PIVOTED GRIPPING TOOL HAVING REMOVABLE SWIVELLY MOUNTED JAWS Filed March 3, 1967 if ;y W 112% J pm my United States Patent 3,383,963 PIVOTED GRIPPING TOOL HAVING REMOVABLE SWIVELLY MOUNTED JAWS Wallace R. Vondrachek, Rte. 6, Box 40, Burlington, Wis. 53105 Filed Mar. 3, 1967, Ser. No. 620,429 7 Claims. (Cl. 81423) ABSTRACT OF THE DISCLOSURE A gripping tool for obtaining a tight purchase on an object from any given angle, said gripping tool having a pair of movable jaw arms with a supplemental jaw swivelly mounted within one of the jaw arms and a bearing surface mounted within the other jaw arm.
This invention relates to improvements in a gripping tool and more particularly, to improvements in a tool or instrument for holding, twisting or turning an object from any accessible angle.
Accordingly, a primary object of this invention is a gripping tool with a swivelly mounted supplemental jaw that is pivotal about an axis at substantially right angles to the gripping face of the jaw arm Within which it is mounted.
A further object is a gripping tool that will grasp any given object from any accessible angle and not release or slip off the object during work.
Another object is a versatile gripping apparatus that is not limited in size and is adaptable to a variety of uses in such fields as mechanics, construction or dentistry.
Another object is a gripping tool or instrument with a 3-point contact that provides a tight purchase while holding, twisting or turning an object.
Another object is a gripping tool that is economical and easy to construct with removable parts that may be quickly and easily interchanged.
Other objects will appear from time to time in the ensuing specification and drawings in which:
FIGURE 1 is a top view of a preferred embodiment of this invention;
FIGURE 2 is an enlarged sectional view taken along line 2-2 of FIGURE 1;
FIGURE 3 is a sectional view similar to the crosssection shown in FIGURE 2 showing another modification of this invention;
FIGURE 4 is a top view of another form of the gripping tool;
FIGURE 5 is an enlarged sectional view taken along line 5-5 of FIGURE 4 showing the supplemental jaw and bearing surface in an alternate position;
FIGURE 6 is an enlarged view of another form of the bearing surface; and
FIGURE 7 is an enlarged partial view of another modification of this invention.
The gripping tool 10 consists of three basic parts: a pair of movable jaw arms 12 and 14, a supplemental jaw 16 swivelly mounted in one of the jaw arms, and a hearing surface 18 mounted in the other jaw arm. The swivelly mounted supplemental jaw 16 is in opposed relationship with the bearing surface 18, and is pivotal about an axis at substantially right angles to the gripping face 19 of its respective jaw arm.
The jaw arms 12 and 14 are movable so that they may be quickly and easily opened and/or closed about an object, and are shown in the figures as pivotal about a pivot point 20. However, it is important to note that the jaw arms may be opened and closed by any suitable means such as by use of a worm gear and rack.
The swivelly mounted supplemental jaw 16 may be atice tached, mounted or seated within its respective jaw arm 12, and may include a rounded shank portion 22 as shown in FIGURES 1 through 6. The shank portion 22 may include a circumferential groove 24 as shown in FIGURES 2 and 5. The rounded shank portion 22 may .be held in place by one or more press fit pins 26 that will allow the supplemental jaw 16 to freely pivot or rotate about an axis substantially perpendicular to the gripping face 19 of the jaw arm 12.
Another method of mounting the supplemental jaw 16 is shown in FIGURE 3 wherein it is removably spring loaded within its respective jaw arm 12. This type of mounting may be accomplished by use of a detent ball 28 and coil spring 30 seated within the rounded shank portion 22. The detent ball 28 fits into a groove 32 in the jaw arm 12, and may be depressed into the shank portion 22 when removing the supplemental jaw.
FIGURE 7 shows still another method of swivelly attaching the supplemental jaw 16 to the jaw arm 12. In this form a rounded shank portion is integral with the jaw arm 12 forming an adapter 34 about which the supplemental jaw 16 may be swivelly mounted. The adapter 34 fits into an aperture 36 in the supplemental jaw allowing free rotation of the supplemental jaw. An O-ring 38 or circular spring may be mounted in a groove 39 around the circumference of the adapter 34. As shown in FIG- URE 7, the O-ring rides in another groove 40 on the inner surface of the aperture 36.
It is important to note that there are other ways and methods of swivelly mounting or attaching the supplemental jaw 16 to the jaw arm 12, and it should be understood that the three methods shown and described are not conclusive, but merely illustrate three preferred methods.
In addition, the supplemental jaw 16 preferably includes a gripping face 42 to provide increased leverage during work. The gripping face 42 is best seen in FIG- URES 1, 4 and 7, and is preferably V-shaped with a plurality of gripping teeth.
The bearing surface 18 is associated with the other jaw arm 14, and may be cylindrical or disc shaped as shown in FIGURES 1, 2 and 3. In this embodiment the bearing surface 18 may either rest on or be seated within the jaw arm 14 providing a 3-point contact with an object. In addition, this form of the bearing surface may have a gripping face to facilitate holding an object during work.
The bearing surface may be either removably or permanently mounted or seated within the jaw arm 14. It is shown in FIGURES l and 2 as removably spring loaded in much the same manner as the supplemental jaw shown in FIGURE 3. A detent ball 44 and coil spring 46 are mounted within a rounded shank portion 48 with the detent ball riding in a groove 50 in the jaw arm 14 to allow free pivotal movement during work. When removing the bearing surface 18 from the jaw arm 14, the pressure on the detent ball 44 will cause it to retract into the shank portion 48 making it easy to remove.
FIGURE 3 shows another suggested method of mounting the bearing surface in the jaw arm 14. In this form the bearing surface 18 has a square shank 51. It is important to note that it is possible for the bearing surface to have a square shank since it is not essential that the bearing surface pivot or rotate.
The bearing surface may also be shaped to conform to the size and shape of the object to be twisted or turned during work. One such modification is shown in FIG- URES 4 and 5, wherein the bearing surface 18 is shaped like the supplemental jaw 16. In this form the bearing surface 18 is again removably spring loaded in the jaw arm 14 having a rounded shank portion 48 with a detent ball 44 on the end of a coil spring. During pivotal move- 3 ment of the bearing surface 18 the detent ball 44 rides in a groove 50 on the inside surface of the jaw arm 14.
Another modification is shown in FIGURE 6 wherein the bearing surface 18 has a plurality of ilat connecting surfaces to snugly lit around a nut, bolt or head of a screw. Here again the bearing surface 13 is shown having a rounded shank portion 48 with a detent ball 44- riding in a groove 50 on the inside surface of the jaw arm 14.
A means to help reduce friction during pivotal movement of the supplemental jaw 16 or bearing surface 18 may be provided and is positioned between the supplemental jaw or bearing surface and its respective jaw arm. This means may be a washer 52. made from a material with a low co-efficient of friction. Another means for reducing friction during pivotal movement may consist of caged roller bearings seated in the surface of its respective jaw arm to contact the supplemental jaw or bearing surface and allow free pivotal movement.
The use, operation and function of this invention are as follows:
When holding, twisting or turning an object the V- shaped face of the supplemental jaw 16 will cooperate with the bearing surface 18 to provide a tight purchase during work. This feature, along with the important feature that the supplemental jaw 16 will pivot or rotate about an axis substantially perpendicular to the gripping face 19 of its respective jaw arm 12, make this tool the answer to many problems in any exacting trade. In other words, the swivelly mounted supplemental jaw 16 allows the gripping tool 10 to grasp an object from any accessible angle without the worry of slipping off the object during work.
The structure of this invention has been shown and described in connection with a common pliers, but it should be understood that it may be adapted for use with other tools or instruments such as wrenches, dental tools or hoisting apparatus. When this invention is incorporated with a common pliers it should be noted that the supplemental jaw 16 will pivot or rotate about an axis substantially perpendicular to the axis of the jaw arms shown at 20, Again, as mentioned above the swivelly mounted supplemental jaw 16 allows the user to grasp an object from any accessible angle, and turn or twist the object in any convenient plane or are without the worry of slipping off during work.
The parts of this invention may be mad from any suitable material that is strong and durable such as steel. In addition, this invention is not limited in size, and may be used, for instance, to grasp large cylindrical or irregular shaped objects.
It is understood that this invention is not confined to the particular construction or arrangement of parts herein illustrated and described, but embraces all such modified forms thereof as may come within the scope of th following claims.
