Oct. 7, 1958 L. PATRICK vxs HAVING SLIDABLE AND TURRET JAWS Filed June 20 1957 INVENTOR fadim r @Zzzbi HA; ATTORNEY United States Patent 2,854,875 VrsE HAVING SLIDABLE AND TURRET JAWS Ladimer Patrick, Kettering, Ohio Application June 20, 1957, Serial No. 666,882

Claims. (Cl. s1--20 This invention is directed to a vise, and particularly to a vise which is easily and efiiciently manufactured from parts which are made, for the most part, from bar stock and castings of a simple nature, thus to provide a vise of high quality and of low cost.

An object of this invention is to provide a vise with a rotatable turret jaw, in which the jaw is held by a bolt construction allowing the tightness of the bolt to be easily adjusted to secure the desired turning ease of the turretjaw.

Another object of this invention is to provide a vise in which a turret jaw and a longitudinally movable jaw are mounted on a straight rectangularly sided bar, which bar is held on the base by two bolts which additionally serve to secure the turret jaw and a stationary screw post on the vise.

Another object of this invention is to provide a vise having a longitudinal base with a transverse cross section for part of its length in the form of an inverted T and another part of its cross section in the form of a U, the surfaces of these two parts of the base being in the same horizontal plane and holding a flat rectangular bar on said surfaces, the construction being such that a turret jaw may be rotationally mounted on the U part of the base and the longitudinally movable jaw and stationary post therefor may be positioned above the inverted T part of the base in such a manner that the movable jaw may slide on the bar, and may have a flanged engagement therewith along its edges, and the turret jaw may be mounted to rotate freely above the bar by means of a single bolt which-also secures the bar to the base, the post also being held by a single bolt which holds the post to the bar and the bar to the base.

Another object of this invention is to provide a vise having a turret jaw with a plurality of sides in which at least one of the sides has a V-shaped groove with a longitudinal cut to enable the sides of the groove to be machined to a smooth finish.

Further objects of this invention will become apparent as the description proceeds with reference to the accompanying drawings, in which:

Figure l is a top plan view of the vise.

Figure 2 is a vertical, longitudinal cross section taken along the line 22 of Figure 1.

Figure 3 is a transverse, vertical cross section taken along the line 3-3 of Figure 2.

Figure 4 is an exploded view of the vise, in perspective.

A vise, according to this invention, includes a longitudinal base 10, which has a transverse cross section in the form of an inverted T for part of its length, from shoulders 11 to a main end wall 12. Another part of the length of the base It] is in the form of a U, such part extending from the shoulders 11 to a main end wall 13.

The base also has slotted extensions 14 and 15 to re ceive bolts for securing the vise to a bench, or the like. A bottom 19 of the inner surface of the U portion of the base 10, and a top portion 20 of the inverted T are in the same horizontal plane. A horizontal, flat, rectangularly cross-sectioned bar 22 rests on the fiat

continuous surfaces

19 and 20 of the base. The width of the bar 22, indicated at an edge 23, is slightly smaller than the width of the bottom 19 of the U-shaped portion 19, as indicated at an edge 24, the bar fitting snugly within the upwardly directed branches 25 and 26 of the U-shaped portion of the base. The width of the bar 22 is greater than the width 28 of the top portion 20 of the inverted T of the base, so the bar 22 has outwardly extending edges 30 beyond sides 31 of the top surface of the inverted T, as indicated in Figure 3.

The height of the bar 22, as indicated by an edge 33, is slightly lower than the height of the shoulders 25 and 26 of the U-shaped portion of the base, so the

top surfaces

34 and 35 of such shoulders are slightly higher than the top surface 36 of the bar 22. The

surfaces

34 and 35 thus provide a sliding surface support for a flat turret jaw 60 hereinafter to be more fully described. A predetermined clearance 22a is provided between the bar 22 and the bottom of the turret jaw 60.

A stationary vertical post 40 is secured on one portion of the bar 22 which rests on the surface 20 of the base 10. The post 40 has a horizontal tapped opening 41 extending longitudinally of the vise, to receive a longitudinal screw 42 for turning movement therein. A longitudinally movable jaw 45 rests on this portion of the bar 22 with downwardly and inwardly extending flanges 46 and 47 (Fig.

3) surrounding the outwardly extending edges 30 of the I bar 22. The construction is such that the jaw 45 may move longitudinally on the bar 22, but cannot be substantially lifted from such bar.

The screw 42 has one end 50 secured to the movable jaw by being rotationally inserted in an untapped opening 51 in the jaw 45, and by being provided with a groove 52 for the reception of the pin 53, which produces a thrust bearing between the jaw 45 and the screw 42. The pin 53 is slightly shorter than a hole 53a within which it is tightly fitted and from which it may be knocked out to remove the screw 42 from the jaw 45. A nurled knob 59, or other form of handle, forms means for turning the screw 42.

The stationary post 40 is secured to the bar 22, and the bar 22 is secured to the base 10, at one end, by means of the upwardly directed bolt 54, having a head 55 hearing upwardly toward the bottom of the base 10, and passing loosely through openings 56 and 57 respectively in the base 10 and bar 22, and threadedly engaging a vertical tapped hole 58 in the post 40 to secure the post 40 to the bar 22, and one end of the bar 22 to the T portion of the base 10.

The flat turret jaw 60, of square horizontal cross section, or other polygonal cross section, is rotationally mounted above one end portion of the bar 22 by a downwardly directed bolt 61 having a head 62 downwardly bearing toward the flat jaw 60, and preferably against an annular shoulder 63 within the flat jaw 60, which is formed by the change in diameter of openings 64 and 65. The head 62 is provided with a hexagonal wrench opening 66 for the reception of an Allen wrench, or the like, to be used as hereinafter described. The bolt 61 passes loosely the vertical holes 64 and in the jaw 60 and a vertical hole 68 in the base 16. The bolt 61 threadedly engages a tapped hole 69 in the fiat bar 22. A jam nut 70 is placed over the end 71 of the bolt 61 which securely holds the bar 22 downwardly on the base 10 by reason of the upward bearing action of the jam nut 74) toward the bottom of the base Ml. The closeness or looseness of the jaw 64? with relation to the

top surfaces

34 and 35 of the U portion of the base 10 is regulated by turning the bolt 61 with an Allen wrench inserted in the hole 66, and by turning the bolt to obtain the desired holding action on the jaw 60 for easy loose turning thereof. Thereafter the jam nut 70 is tightened to produce a pulling action between the bottom of the base and the bar 22. Proper manipulation of the Allen wrench and a wrench on the nut 70 produces the desired clearance between the lower surface of turret jaw 60 and the

top U surfaces

34 and 35.

The.

jaws

45 and 60 are adapted to receive and hold a plurality of differently shaped pieces between them. To this end, the jaw 45 is provided with a large, fiat vertical face 80 and a horizontal step of groove 81 near the top. Also a vertical V-shaped groove 82 is placed near the center of the jaw 45; The turret jaw 60 preferably has upper and lower parallel faces. One of the sides of jaw 60 has a horizontal groove 85 adapted to hold cylindrical rods or tubes against the fiat face 80 of the movable jaw 45. Another face of the jaw 61 has a small vertical V-shaped groove 86 adapted to hold relatively small cylindrical or otherwise shaped rods in vertical position in cooperation with the vertical groove 82 heretofore described. Another face of the jaw 60 has a relatively large vertical groove 88 adapted to hold in vertical position cylindrical or otherwise shaped articles in cooperation with the vertical groove 82 of jaw 45. Another face of the jaw 60 has a large fiat face 89'adapted to hold fiat pieces, wedge-shaped pieces, or otherwise-shaped pieces-between the

faces

89 and 80. A V-shaped groove 90 is placed at the upper end of the groove 86, to hold discs, or the like, in horizontal position in cooperation with the groove 81 on the jaw 45. In a similar manner, a V-shaped groove or step 91 is placed above the vertical groove 88 and is likewise adapted to hold discs or the like of larger dimension in cooperation with the groove 81 of jaw 45. A horizontal groove or step 92, above the flat face 89 is adapted to hold flat pieces in cooperation with the groove 81 of jaw 45.

Small vertical central grooves 93 and 94 are placed at the apexes of the V-shaped grooves 86 and 88 to permit the faces of these grooves to be machined to a smooth finish. A similar groove 97 is made at the apex of the V-shaped groove 85 to permit machining of these surfaces.

If desired, a depression 100 is placed on the upper surface of the jaw 60 for the placing of the name of the manufacturer or the purchaser. Also the bottom of the base 10 may be provided with circular, oblong, or rectangular cut outs 101, 132 and 10.3 to lighten the weight of the base 10.

Many of the parts used to manufacture the vise may be v purchased as stock pieces, or may be cut from stock bars, or the like. For example, the screw 42 may be cut from long, threaded bar stock. The bar 22 and the part 40 likewise may be cut from long stock bars. The base 10 may be cast and roughly machined, and only the surface 19 and need be treated in this manner; The rotatable jaw 60 may be made from bar stock of slightly larger dimension than the finished product or may be cast and then roughly machined to final shape, after which it may be case hardened and machined to final dimension.

The entire vise can be assembled and held together by the two

bolts

54 and 61. The movable jaw 45 rides smoothly on the bar 22. The correct looseness of turning movement of the jaw 69 may be calibrated by turning the bolt 61 in relation to the bar 22 so that the proper clearance is provided between the jaw 60 and the

faces

34 and 35. Thereafter the jam nut 70 is tightened without materially affectingthe calibration of the jaw 60 with respect to its turning movement.

Thus it is to be seen that I have provided a very efficient turret vise which can be manufactured at a very low price.

While the preferred form of the invention has been disclosed, as required by statute, other forms may be used, in accordance with'the scope of the claims which follow.
