. Application filed January 22, was. Serial No. 614,166.

To all whom it may] concern:

Be it known that I, ALBERT G. .VoL'rz,-a

citizen of the United States, and resident also into various angular positions with'ree lation to the horizontal and about the same axis. 'j i It is also an object to provide an improved clamping jaw of a removable character, with improved means for detachably secur-ingthe same to the supporting arm of the vise, in which connection provision is also made for so securing bothjaws of the vise to their supporting arms as to permit attachment and removal of the jaws only by a movement in opposite directions. I p i A furtherlfeature of the improved construction resides in the type of clamping j aw, theupper margin of which is of laterally inclined form, for affording a wider clamping surface and also enabling thework to'be positioned at such an angle as to clear the lower parts of the vise o Y With these general ob'ectsin view, as well as minor objects as will hereinafter, appear,

the invention will now be described by reference to the accompanying drawings illustrating one. form. of construction which I have devised for embodying the proposed features of improvement, after which) those parts and combinations "deemed .to 'be novel will be particularly set forth and claimed.

. In the drawings- ,p p

and illustrating a piece of-work in relation to vone of the clamping jaws;

' Figure 5 is'a perspective view showing the clamping jaws;

the tongue construction of the upper end of Figure 9 is a similar section lookingin the opposite direction. 7 I Referring now tothe drawings in detail, these illustrate the improved vise construc} tion as comprising a pair oflrelatively mo-v able jaw s'upporting arms 10, 11, the arm 11 being formed with a "shank extension 12 mounted for sliding movement through guide passage 13 provided in the base 14 forming the lower portion of the arm-10. Within said passage 13 is provided a view of one of v threaded lug 15 engaged by an operating. 7 screw 16 extending througl'i the shank member'12 ofthe arm 11', one end ofsaidf screw 1 6:beingiournaled inan'opening 17 pro vided in the lower end of the arm 11, and

fitted witl'r'a knob 18 provided with-an opcrating handle 19 "slidably carried byjsaid knob 18in the usual manner, f

The underfaceof' thebase portion Hot the arm-1O is forn1ed with'an jinc lined sur face, adapted to be supported uponj a similarly inclined surface provided by the upper I faceofa supporting block 20, the shap'efof which is substantially that of a right-tr m; Gated, cylinder, as clearly illustrated in Figu'res'l and 3. Within'the-underface of'the base portion 14 is formed an undercut groove 21 for accommodating aplate '22 adapted to be fitted in place by insertionthrough the outer end'of said groove 21, and formed with a socket portion 23 for pivotal engagement with the head 24t'of-the upper end of a pin 25, the slide 'plate'22 being secured in'position-by'meansof a screw 26 (see Figure 8.).

The pin25- extends through a plate 27 provided as a support for rotatably carrying the block 20, the plate 27 being in turn car,- ried by the upper fac'e ofthe-table orfbench 28. Accordingly, a Suitable openingv is provided in the table or bench 28 for the pas providedwith a forked handle 30 for the sagelot' the-pin 25, the lower end of which is threaded torreceivmg a. clampingnut 29 pin 25. The upper taee of the' plate 271's provided with a set of radially arranged lugs 31 for engagement with ditl'crent points of the lower end of theblock 20, as shown in Figure 2 the outer portions of these lugs 31 being formed with spaced ribs 32, and a third pair of ribs 33 being formed opposite the middle lug 31, for engagement with the heads of bolts 34 provided for securing the plate 27 in fixed position on top of the table 28. ()pposite the middle lug 3.1, the plate 27 is also formed with a lug 35 for the mounting of a screw 36 fitted with an operating handle 37, whereby the screw 36 may be actuated into clamping engagement with the lower portion of the block 20, to force the latter into secure clamping engagement with the set of lugs 31.

As shown in Figure 9, the upper face of the block 20 is formed with a series of openings 40, which are designed for receiving the inner end. of a latch screw 41 mounted in the lower margin of the base portion 14 of the arm 10, whereby said base portion 14 may be securely retained in any desired position to which it may be rotated about the axis of the pin 25. Preferably, the upper margin of the block 20 is provided with a series of marks 42 for indicating the position of each of the openings 40 and thus facilitating the registering of the screw 41 therewith.

Each of the supporting arms 10 and 11 is formed at its upper end with a substantially dovetailed. tongue or tenon 45, tapering laterally but in opposite directions, these tongues or tenons 45 being provided for the removable mounting of a pair of jaws 46 formed with undercut tapered grooves 47 of the same taper as the tongues 45, so that the jaws 46 may be interchangeably mounted on either of the arms 10 or 11. The upper margins of these jaws 46 are inclined laterally in the same direction (see Figures 3, 4 and 6), although under some conditions it may be preferred. to use jaws 46, (as illustrate-d in Figure 7) formed with the usual plain horizontal upper faces. In the case of the inclined upper margins, the angle of inclination is such as to cause a line drawn at right angles to the top surface of the jaw and intersecting the lower end thereof to extend clear of the shank member 12 of the arm 11, as clearly indicated in Figure 4. Preferably, the shank member 12 is formed with beveled upper corners 12' (see Figures 2 and 4), and the upper corners of the base 14 are similarly beveled, as indicate-d at 14, at the rear of the arm 10.

Besides having their opposed faces designed to operate as clamping surfaces for engagement .with the work, the upper or outer faces of the aws 46 may also be used as anvil faces in an obvious manner, and for lending greater support for these portions of the jaws, the anvil side of the groove 47 of each jaw is extended back over the corresponding supporting arm materially farther than the lower or opposite side of the groove, and each of said. supporting arms is formed with a shoulder 50 adapted for engagement with the outer or rear edge of the anvil portion of the corresponding jaw.

In the operation of the device, it will be noted that the aws 46 may be applied to the upper ends of the supporting arms 10 and 11 only by a movement in opposite directions, due to the opposite taper of the tongues or tenons 45, so that consequently the jaws, when in clamping engagement with the work, will mutually oppose any tendency of either of the jaws to become displaced from supported engagement with the tongues The jaws are thus both held securely in position, since any movement of either jaw in a direction tending to remove the same from its supporting tenon ill not only be opposed by its companion jaw but will also tend to tighten the latter jaw in place. The inclined form of the upper margins of the jaws also affords a wider type of jaw, or one having a more extended. engagement with the work, such as a sheet of metal 52 (see Figure 4) besides which, this angular jaw outline facilitates the positioning of the work in such a way as to clear the shank and other lower parts of the vise, as in cases where it is desired to bend the material 52 about the line of engagement with the jaws. It is apparent that the work 52 may be supported in oppositely inclined position from that shown in Figure 4 by simply'reversing the arrangement of the jaws 46, that is, simply interchanging them upon the arms 10 and 11. This angular form of the jaws, and the manner in which they enable the work to be carried at an angle, as illustrated, is of importance, as in the usual construction the dropping of the work below a certain point is blocked. by the lower part of the vise structure, and the clearance afforded by the applicants construction is further increased by providing the

beveled corners

12 and 14, as above explained. Of course, the beveled corners 14 are not involved except in those cases where a double bend is to be produced in the stock 52 and requiring the first bend to be extended down back of the arm 10. The mode of supporting the vise upon the truncated cylinder block 20 enables the vise to be swung into any desired position about the axis of the pin 25, which movement brings the vise structure into various different angular relations or inclinations to the horizontal, one of which'is shown in Figure 1. This function of the apparatus is one of great advantage, inasmuch as it both facilitates the positioning of the work in the manner best suited to the workman, and also enables this adjustment as to position to be effected with the leastinter= Inn responding opening 40 and the pin 25 is again tightened by operation of the nut-29. 'Thus the pin 25 operates not only as a retaining means for holding the vlse structure upon the block 20, but also as a pivotal connection forming the pivot axis about which the base portion 14; of the arm 10 rotates with reference to the top surface oflthe -about the same axis or pin 25.

block 20. This block may also be rotated upon the plate 27 and secured in any desired position upon said plate 27, so that any desired angular position of the vise may be maintained while rotating the block 20 7 By this means, it is apparent that the jaws and work ,engaged therewith may be rotated into any desired position about th-eaxis of the pin and to any elevation between the upright or maximum elevation illustrated inFigure 3 and the lowermost or minimum elevation corresponding to that shown in Figure 1. All operations required of vise structures are thus greatly facilitated by the flexibility of the structure herein described, sincethe jaws 46 are very easily detached, put in place or interchanged, and all of the adjustments above explained are readily efiecteda As shown in Figure 3, the block 20 is formed with a sufficiently large borefor the pin 25 to prevent binding the latter within the block, and thus permit free turning of the block about the axis of the pin, also,

the socket member'23 is'seated, in a suitable recess 23 formed at the upper end of said bore, thereby preventing any sliding of the base 14 down the inclined upper face of said block. Furthermore, any turning of the pm 25 is prevented by means-of a washer 38 secured to the under face of the bench 28 and formed with an internal tongue 38 engaging a groove 25' in the lower end portion of said pin 25. i

While I have shown and described what I now regard as the preferred form of embodiment of the proposed improvements, I desire to reserve the right to make all such changes or modifications as may .fairly fall within the scope of the appended claims.

I lVhat I claim is:

1. A visecomprising a pair of relatively movable supporting arms, and a pair of jaws supported by said arms in parallel relation, said jaws and arms being formed with inter-engaging tongues and; grooves permitting the application and removal of said 'aws said ton 'ues bein ta )ered in o 3 )osite.

a a o directions.

2. A vise comprising a pair of relatively movablesupporting arms, and 'a pair of aws supported by said arms in parallel relation,

said jaws being each provided with a lateral- 1y extending tapered tongue and said jaws being formed with tapered grooves for removable engagement. with said tongues, the

tongues of said arms beingv tapered in opposite directions.

3. A vise comprising a pairof relatively 'movable supporting arms, and a pair of jaws supported by said arms in parallel relation, the upper margins of said aws having an inclination in the same direction laterally withreference to the line of relative movement of the jaws. v

4. A vise comprising a pair of relatively movable supporting arms, one of said arms having a shank member. slidably engaging the other arm, and a pair of jaws supported by said arms in parallel relation, the'upper margins of said jaws being inclined laterally with reference to the line of relative movement of the'jaws and at such an angle that parallel lines intersecting therespec'tive ends of either of said margins'at right angles thereto will both project to one side ofand clear said shank member.

In witness whereof I hereunto afiixmy signature.
