Claims. (01. 81-17) This invention relates to a vise and has for its general object the provision of a vise on which many operations may be performed which could not be performed with previously known vise structures and other operations can be performed with greater facility than with previously known vise structures.

It is the primary object of this invention to prodirectly or with a shearing movement, or in which an article may be bent to a complex shape, as well as a vise in which various other operations can be carried out.

Other objects and advantages of this-invention will become apparent from the following description taken in connection with the accompanying drawings wherein is set forth by way of illustration and example one embodiment of this invention.

In the drawings:

Figure 1 is a perspective view showing a vise constructed in accordance with this invention.

Figure 2 is an exploded view still in perspective illustrative of the same vise as shown in Figure 1 but with the parts separated slightly from each other so as to provide a more detailed illustration of their structure.

Figure 3 is a top plan view of the gripping jaws and associated parts of the vise illustrated in Figure 1.

Figure 4 is a side elevation of the vise illustrated in Figure 1. I Figure 5 is a detailed view of a fragment of the vise shown in Figures 1 to 3 and illustrating a portion of the means for shifting the jaws of one pair of jaws laterally toward and away from each other.

Figures 6 to 10 inclusive are fragmentary perspective views showing the gripping portions only of the jaws of the vise and illustrating various operations which may be carried out with the vise constructed in accordance with this invention.

Referrin now more in detail to the drawing, it will be seen that the vise as illustrated-in Figure 1 is adapted to be mounted upon a table I 2 or other like support, although it will be appreciated that some other form of support may be employed. In the instance illustrated, the base 2 of the vise is secured by means of leg screws 3 to the table I, these leg screws passing through suitable lugs 4 formed integral with the base 2.

In the instance illustrated the base of the vise is provided with a swivel mounting of a well known type, the part 5 being adapted to swivel upon the base 2 and to be clamped in place in a desired position by means of a clamping screw 6. Rigidly carried on the base member 5 in the usual fashion is a guide 1 adapted to receive the slide bar 8, and the slide bar 8 is adapted to be moved to and fro within the guide I by means of a'screw 9 having a handle 9a.

The vise as described up to this point is of more or less conventional construction and is to be understood that the details of construction need not be exactly those illustrated or described but may be any other conventional vise construction not inconsistent with the features of this invention presently to be set forth, whether such details be details now known to be conventional, or details which may become known in the future.

Coming now to the features which distinguish this invention and by which it is enabled to perform the desired results, base member 5 is illustrated as having mounted above the guide I a guide [0 which is disposed at right angles to the guide 1 and is adapted to receive a slide H which by virtue of this mounting may slide in a direction transversely to the direction of movement of the slide 8. The slide H is adapted to be moved transversely along the guide [0 by means of a screw 12 which lies in a groove provided for the purpose in the upper surface of the guide l0, such groove'being smooth on its inner surface so that the screw l2 may freely rotate therein. Screw i2 is provided with a reduced section 13 intermediate its ends, which section l3 fits within a likewise reduced portion of the groove in the guide [0, so that the screw l2 will be permitted to rotate but not to move endwise with respect to the guide 10. The screw It is noted that the screw 12 lies about half in the groove in the guide and is adapted to extend along its upper half in a somewhat similar groove within the lower surface of the slide H. The difference, however, is that the interior of the groove in the slide H is threaded to receive the screw threads l5 and I6 whereby upon rotation of the screw 12 the slide ll will be moved along the guide it) in one direction or the other.

On its upper surface the slide l I is itself formed with a guide H which may be termed a jaw guide inasmuch as it is adapted to receive and guide the jaws l8 and I9. These jaws l8 and I9 form a pair with slide portions engaging the guide El and with threaded portions in a half groove in their respective under surfaces which threaded portions are adapted to receive the oppositely threaded sections 26 and 2! of the screw that is rotated and mounted in a half groove in the :upper surface of the guide N. that this screw has two threaded sections and is in that manner similar to the screw 12, but that it differs from the screw 12 in that the two threaded sections 29 and 2! are oppositely threaded, that is one is threaded with a right hand threadand the other with a left hand thread, so that when this screw is rotated the two jaws l8 and [9 will be moved simultaneously toward-or away from each other. Intermediate these two threaded sections this screw is formed with a reduced portion 22 fitting in a reduced part of the groove in the guide I! for the purpose of preventing endwise movement of the screw within the guide in the same manner as described in connection with the screw Hi. This screw in the guide I? may be rotated by means of a wrench fitting into a noncircular hole 23 in one or both ends of the screw or in any other suitable fashion.

The gripping jaws i8 and it are providedwith gripping faces, there being two such faces on each jaw. One of these faces 24 on the jaw I8 faces toward the jaw l9 and the other face 25 on the jaw it faces toward another pair of jaws as will presently be described. In the same fashion, the

gripping face 26 on the jaw l9 faces toward the jaw 18 and the gripping face -21 on the jaw l9 faces toward the other pair of jaws which will be described.

Referring now to the mounting for the other pair of jaws referred to, this consists of a jaw guide 28 which extends in a direction parallel-to the guides l0 and I? previously described and which is adapted to receive for transverse sliding movement the jaws 29 and 30. These jaws are provided with threaded half grooves in their under surfaces in the same fashionas the jaws l8 and I9, and also in the same fashion these threaded half grooves are provided with reversely threaded portions, that is, one portion in the jaw 29 may be of right hand thread and the portion in the jaw 36 .of left handthread, or vice versa. There is also provided a screw having reversely threaded portions 35 and 32 adapted to fit with the threaded half grooves in the jaws '29 and 38 respectively so as to move these two jaws in opposite directions when the screw is rotated. The screw is prevented from endwise movement within its half groove in the slide 28 by the reduced mid-section 33 which fits within a portion of the groove in the slide 28 which is of correspondingly reduced cross section. The screw may be rotated in any suitable fashion as by means of a key or wrench inserted in a noncircular hole 34 in the end of the screw.

The jaw 29 is provided with a gripping surface.

It is to be noted 3'5 which faces toward the jaw and with a gripping surface 35 which faces toward the opposed pair of jaws l8 and 19. Likewise, jaw 30 is provided with a gripping surface 3! which faces toward the jaw 29 and with a gripping surface 38 which faces toward the opposed pair of jaws l8 and [9.

In operation it will be seen that the vise just described may be used as an ordinary vise by moving the two pairs of jaws l8 and [9 on the one hand and 29 and 39 on the other hand until their respective gripping surfaces 24 and 26, and 3E and 37, are in contact, and by moving the slide ii until it is centered on the guide ill. However, these two jaws thus formed by bringing together the twopairs of jaws may be offset laterally from each other by operation of the screw 12 to move the slide I l to the one side or to the other. Such rotation of the screw l2 will of course result in the shifting of one of the two pairs of jaws as a unit in a direction laterally with respect to the other pair. That is, the movement of shifting will be a shearing movement. v

It will also be apparent that both jaws of either pair may be simultaneously moved apart so as to separate their gripping surfaces 2 3 and 26 or 35 and 31 as the case may be.

The numerous applications to which a vise of the character described may be put cannot all be set forth herein, but some are illustrated in Figures 6 to 10, inclusive, of the drawings.

In Figure 6 there is illustrated a situation in which two fiat members 39 and ll] are gripped in overlapping relation to each other but with their overlapping parts free of any gripping members so that they may be punched or perhaps, if desired, drilled by means such as a drill 4!. Any other desired operation may be performed on these overlapping parts without interference from the gripping portions of the vise.

, With reference to Figure 7,. it will be seen that the vise may be employed for the purpose of gripping a strip of material 42 having an intermediate offset portion '33 so that the two ends of the strip of material are not in the same plane. It will further be appreciated that a strip of material which does all lie in a single plane may be bent to the shape of that illustrated in Figure 7 by first gripping it between the individual jaws of the two pairs of jaw respectively, and by then manipulating the screws 9 and 12 to bring the two pairs of jaws closer to each other and to simultaneously cause them to move laterally with the shearing motion with respect to each other so as to produce the central offset portion 43.

In Figure 8 there is illustrated an operation in which a pin or bar i l may be forced through an opening in a plate 45 or the like, the jaws l8 and 9 for this purpose being separated from each other so as to permit the bar a: to pass between them, and the jaws 2a and .38 being moved together so as to contact the end of the bar 44 and force it through the opening in the plate 45. In such an operation the bar i-l might be forced into tight engagement with the plate .45 or might be forced out of the plate 45, as desired.

In Figure 9 the vise is illustrated as being employed for the purpose of gripping an irregularly shaped member 56 having laterally extending flanges or parts 4'! and At which are out of alignment with each other. With an ordinary vise it would be impossible to grip this memher on both sides of the flanges ll and Q8, but with this vise not only may the main body portion of this irregularly shaped member be gripped on both sides of both of the flanges 41 and 48, but thefianges 41 and 48 may themselves be gripped between the individual jaws of the respective pairs of jaws.

In Figure there is illustrated a situation in which a fiat member 49 may be gripped in such fashion as to leave its central portion free for the work such as filing, drilling, or the like. At the same time, both end portions of the member 49 are gripped tightly so that there will be no excessive vibration or looseness to interfere with the accuracy of the work.

Many other operations than those illustrated and described may be carried out with a vise constructed in accordance with this invention,

and it will be appreciated that the details of construction of the vise itself may be varied and that in certain instances wherein all of the advantageous features of this vise may not be necessary, some of them may be omitted and others employed.

It will thus be seen that a structure has been described and illustrated which is fully capable of carrying out and accomplishing all the objects and advantages sought by this invention.
