Filed Nov. 27, 1959, Ser. No. 855,621 Claims. (Cl. 269-135) This invention relates to a vise, especially one to hold non-ferrous material on a magnetic chuck. It also is suitable to hold any materials on non-magnetic machines.
In precision work, when an article is held by a vise, the article often does not rest flat on the base, and often workmen strike it with a hammer, trying to force it into proper fiat position on said base. The principal object of our invention is to provide a vise, the jaws of which when being moved to tightened position against an article they hold, also move downwardly somewhat, thus forcing the article downwardly so it lies flat on the base.
Another object is to provide said jaws with gripper portions, the free or gripping faces of which extend diagonally, so that when the vise is tightened and the jaws move downwardly, the gripping faces are moved to a position where they bear flush on the article.
A further object is to provide simplified means for moving a jaw support towards and away from tightened position.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and therefore, we are not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specification; but are entitled to all such changes therefrom as fall within the scope of our claims.
In the drawings:
FIGURE 1 is a perspective view of our vise in normal position. v a
FIG. 2 is an enlarged cross-sectional view on the line 22 of FIG. 1, showing an article in broken lines between the two jaws after the vise is tightened.
FIG. 3 is an enlarged, fragmentary, sectional view, showing a jaw, with associated-parts, holding an article in clamping position.
FIG. 4 is a perspective, exploded view showing the various parts forming our device.
As illustrated, our vise has a base having two T- shaped slots 12 in which the square heads 14 of two fastener members such as bolts 16 slide, later described. Said base has one or more screw-threaded holes 18 that extend from the front edge inwardly.
A stationary block 22 has two plain holes 24 therethrough into which counterbored screws 26 extend and screw-threadedly connect in said holes 18 thus joining said block and base. Said block has a larger, screwthreaded hole 28 with which an actuator screw 30 connects having a reduced intermediate portion 31 and which has a handle 32. Said block also has a well or cavity 34 next to said base 10, later described, and two dovetail-shaped slideways 36 at opposite sides.
A jaw support 38 has a dovetail bottom-out 40 that receives said block 22, leaving two opposite depending sides 41 which slide along said slideways 36. A filler member 41a holds said block 22 in place in said cut-out 40. A housing 42 is formed at the underside of said jaw support 38 having a closed end 44 which said actuating screw 30 contacts. A plunger pin 46, having a hollow upper part, extends into said actuator screw reduced portion 31 thus connecting said actuating screw with said jaw support 38 whereby they move together.
Said jaw support 38 has an elongate cut-out 48 at its inner end extending from the top downwardly, and a hole 50 is adjacent thereto into which said plunger pin 46 extends and above which is a coil spring 52, which in expanded position, extends above said jaw support 38 and also enters said plunger pin 46. It also has two screwthreaded holes 54 extending from the top downwardly, later described. A resilient block 58, made of a material such as Neoprene or hard rubber, extends into said cutout 48.
A jaw 60 has, in position of use, an upper portion 62 which resest on said resilient block 58 and is within said cut-out .48, and its outer edge 64 is beveled An intermediate portion 66 extends diagonally downward and inward at an angle of 60 degrees, for instance, from said upper member, leaving a space 67 between it and said block 58. As used herein inwar means toward the other jaw, later described. A gripper portion 68 extends horizontally from said intermediate portion '66 and it has a notch 70 therein to aid in holding a round article, for instance. The tree or gripping edge 72 of this gripper portion 68 extends downwardly and flares in an inward direction at aslight angle, as 3 degrees, for instance, the angle being exaggerated in FIG. 2 of the drawings, for instance. Said gripper portion 68 is spaced slightly above said base 10.
A retainer 74 has two counterbored holes 76 therethrough and screws 78 pass therethrough into and connect with said screw-threaded holes 54 in said jaw sup port 22. Said coil spring 52 is compressed by said retainer 74 when the latter is tightened, thus keeping said plunger pin 46 in said actuating screw reduced portion 31.
Another jaw support 80 is ordinarily held in fixed position, although adjustable. It has .two holes 82 each of which receives a said square head of a bolt 16, and it also has a screw-threaded center hole 84. An elongate cut-out 86 in said jaw support 80, similar to said cutout 48, receives a resilient block 88 similar to block 58.
A jaw 90, similar to jaw 60, has an upper portion 92 that rests on said resilient block 88 and is within said cut-out 86, and its outer edge 94 is beveled. Anintermediate portion 96 extends diagonally downward at an 45' angle of 60 degrees, for instance, leaving a space 97 between it and said block 88. A gripper portion 98 ,extends horizontally from said intermediate portion 96, being spaced slightly above said base plate 10 in normal position, and it has a notch 100 therein. The free or gripping edge 102 of this gripper portion 98 extends diagonally downward and fiares in an inward direction at a slight angle, as 3 degrees, for instance, the angle being exaggerated in said FIG. 2.
A retainer 104 has two plain holes 106 through which said bolts 16 extend. It also has a counterbored hole 108 and a screw 110 extends through it and screwthreadedly connects in the jaw support hole 84. Nuts 112 screw on said bolts 14 and bear on the top of said retainer 104 firmly holding the latter and said jaw 90 in predetermined position on said base 10. To set this jaw support 80 in any desired position, the nuts 112 are loosened and said screw 110 is removed whereupon the jaw support is slid towards or away from said jaw until the desired position is reached. Then said nuts 112 and screw 110 are tightened, firmly holding said jaw support 80 in that position.
When an article 115, shown in said FIG. 2, is placed between said two jaws 60 and 90, said actuator screw 30 is moved to tighten said jaw 60, thus moving said jaw gripper portion 68 into-contact with the article 115 as shown in said FIG. 2. As the tightening pressure is increased said jaw upper portions 62 and 92 deform said resilient members 60 and 90 respectively, and said gripper portions move downwardly, bringing the article 115 down with them and into firm engagement with said base plate 10, shown in said FIG. 3. Before this movement of the jaws, said article 115 was held only by the lower edges of said gripper portions 68 and 98 as shown in said FIG. 2, but this movement downwardly brings the entire gripper edges or .faces of said gripper portions 68 and 98 into contact with said article, thus gripping the latter firmly, as shown in said FIG. .3.
