SCREW VISE FOR RETAINING REGULARLY 0R IRREGULARLY SHAPED OBJECTS Filed July 25, 1947 6 Sad/LE" W 0711660 flag Patented Feb. 13, i951 NT OFFICE SCREW VISE FOR RETAINING REGULARLY R IRREGULARLY SHAPED OBJECTS Sven Erik Wilner 0hlsson, Goteborg, Sweden Application July 25, 1947, Serial No. 763,459

- In Sweden September 29, 1942 Section 1, Public Law 690, August 8, 1946 Patent expires September 29, 1962 The object of the present invention is to provide a screw vise in which work pieces of different shapes can be rigidly set up for working purposes. The screw vise is particularly suitable for such work pieces which are to be worked on a plane top-side but also pieces of other shapes may suitably be rigidly set up, for instance rings and conical pieces. It is to be observed that square parallelepipedic, cylindrical and similar pieces of irregular contour can all be secured in the vise, which also can grip comparatively thin discs.

An embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side-view partly in section of a screw vise according to the invention;

Figure 2 is an end view;

Figure 3 is a plan view of the vise;

Figure 4 shows a modification of a detail; and

Figures 5, 6 and 7 show respectively various manners of usin the vise.

To the frame I there is rigidly connected a base plate 2, the middle part of which forms a dovetail-shaped guide-way for a complementary slide 3, as shown in Figure 2. For gripping the pieces of work the vise is provided with three jaws 4, 5, and 6, the jaws 4 and 5 being disposed on the fixed part of the base plate 2 adjacent one another on each side of the slide 3, and on said slide 3 is so disposed the third jaw 6 that when the slide 3 is moved to the right in Figure 3 this third jaw moves towards the other two jaws.

For moving the movable jaw towards or from the fixed jaws there is rotatably mounted in the frame a swiveled screw 1, which can be rotated by means of a handle 7a. The screw 1 passes through a threaded hole in an ear 8 provided on the slide 3, so that when the screw is rotated the 2 Claims. (Cl. 8138) Starting from the position shown in Figure 3 one can set up between the jaws ordinary straightslide 3 and thus the jaw 6 will move in the one or the other direction.

The jaws are built up of washers or plates l 0 of steel or the like rotatably mounted on pins 9 projecting vertically from the base plate, and said plates in are superimposed one upon another. These plates must be of an absolutely uniform thickness, and well worked so as to snugly fit against each other. They can be individually rotated around the pins 9. These pins can be fixed to the respective parts of the base plate in any suitable manner; for instance, they can be driven into holes provided in said parts. The thickne of the plates may be about 2 millimeters,

lined workpieces of a plane shape. If, for example, such a piece of work has a thickness of about 2 millimeters, one turns aside one of the washers forming the jaws and thereby obtains a plane on the uppermost of the underlying washers on which plane the piece of work can be placed whereupon the jaws are screwed towards each other. Thus it'is possible to turn aside a number of washers corresponding to the thickness of,

the piece of work, and, provided one knows the exact thickness of the washers, one always knows how many millimeters that are to be worked away.

If cylindrical, conical or elliptic pieces are to be set up in the vise, the jaws 4 and 5 (Figure'3) are turned away from each other to form an angle a, as shown in Figure 7, which angle varies according to the curvature of the object ll.

One can now set up cylindrical and conical objects of various thickness, as steps are formed on the jaws when these are turned. If, for example, one has a circular cone, having its butt end downwards, standing vertically between the jaws, as these are shown in Figure '7, the jaws 4 and 5 will turn, washer after washer, exactly after the shape of the cone, thus securing a firm setting up of the piece. In certain cases the washers must be clamped together, because no matter how well the fit of the workpiece between them may have been carried out, displacement may occur when setting up the piece. An arrangement for this purpose is shown in Figure 4. The washers H] are mounted on a bolt l2 rigidly fixed to the slide member 3 and provided with a counter-sunk head t3, and above the washers there is mounted on the bolt I2 a plate I 4 provided with a recess, in'which the head l5 of a screw [6 screwed into the bolt I2 exactly fits. The bottom surface of the recess in the plate I4 has such a position in relation to the top surface of the bolt l2 that an eiiective clamping of the washers can be secured by tightening the screw I6. As implied by Figure 4, the entire device is such that the top surfaces of the jaws will be plane so that nothing prevents the filin or working on the piece of work.

Figure 5 shows how a ring I8 is set upin the vise. In all the jaws, holes Ila are provided in which pins I! can be inserted. If the ring [8 be 3 placed asshown in the drawing and the jaws are brought'japart, for instance, by moving the jaw 6 in thedirection of the arrow by means of the screw 1 the ring will be firmly set up.

The details of the device described and shown can be varied in one or more respects without departing from the spirit of the invention.

What I claim is:

1. A vise comprising a base plate, a vplurality of jaws movably mounted relative to one another along said base plate, a plurality of pins mounted perpendicular to said base plate and each rotatablysupportingone of said jaws, each of said jaws being formed by a plurality of fiat discs positioned one upon another and individually rotatable about their respective pin and said discs being formed rounded at one end and rectangular at the opposite end thereof.

2. A vise comprising a base plate, a plurality of jaws each formed by a plurality of fiat discs positioned one upon another, a plurality of pins perpendicularly mounted upon said plate and each pin rotatably carrying the discs of one of said jaws parallel to said plate, means for sliding one of said pins relative to the others, and said discs being formed rounded at one end and rectangular at the opposite end thereof.
