(c1. iai- 36) 7 Claims.

This invention relates to a vise, more particularly to a vise of the quick adjustable type.

One object of the invention is to provide an iinproved vise of this type employing complementary disengageable screw elements, wherein their operative or inoperative relationship is readily and automatically effected by rotative operation of the feed screw.

Another object of the invention is to provide an improved vise of this type having complementary screw threaded disengageable` elements, cornprising a minimum number of parts for effecting an operating and non-operating relation therebetween.

Another object of the invention is to construct an improved vise of this type comprising a movable jaw provided with a feed screw and interlocking elements between the stationary jaw of the vise and the feed screw, one of said elements being movable and having a threaded portion adapted to removably engage the feed screw and a portion frictionally engaging therewith, whereby rotation of the screw controls the engagement of the threaded portion of the element with the feed screw and the other element and its disen-` gagement therefrom.

Another object of the invention is to provide an improved vise having between its fixed jaw and the feed screw for its movable jaw a member provided with engaging elements and movable transversely and longitudinally relative to the feed screw, said member being supported on and frictionally engaging the peripheral edges of the screw threads of the feed screw, whereby (a) turning of the screw in one direction moves the member laterally to elfect engagement of one element thereof with the screw and permits the screw to move the member in the longitudinal direction to effect engagement of its other element with the fixed jaw and (b) turning of the screw in the opposite direction reverses the movements of the member to eect disengagement of its elements from the screw and xed jaw.

Another object of the invention is to' construct an improved vise of this type having a movable jaw provided with a feed screw and a (nut movably mounted between the fixed jaw of the vise and the feed screw and adapted to operatively engage the feed screw and stationary jaw, the nut havinga portion frictionally engaging the screw, whereby rotative operation of the latter controls the movement of the nut into engagement with the feed screw and stationary jaw and disengagement therefrom.

Other objects of the invention will be apparent to `those skilled in the art to which my invention relates from thek following description taken in connection with the accompanying drawings, wherein Fig. l is a side elevation ofa vise embodying my invention mounted on a suitable support; Y

Fig. 13 is a fragment-ary plan view whereina modified form of screw thread is employed.

In the drawings, I, 2, indicate the inner and outer jaws of the vise shown clamping a work piece A between them. The jaw I yis preferably integrally connected to a base, indicated as an entirety at 3. The base 3 preferably consists of a bottom wall 3a having an end wall or flange 3bl at its front or outer side and ears 3c on its rearward or inner side adjacent the opposite ends of the wall 3a. The base bottom y3a, may be mounted. on the upper side ef a support Bbut in the preplane slightly above the surface of the support'B, whereby tools on the support employed for working on the work piece may be readily picked up and replaced thereon.

The jaw 2 is suitably rigidly connected to the outer ends of a pair of spaced parallel guides 5, the inner ends of the guides` being supported in openings 6 formed in a cross member 1. Each guide 5 is slidably supported in alined openings 3b', 3c', formed in the ange 3b and adjacent ear 3c, respectively. From the above description it will be observed that the jaw 2, guidesV 5 and cross member I form the movable members of the vise and are movable relative to the jaw I and parts connected thereto in the manner later set forth.

8 indicates a feed screw extending parallel to the guides 5 and therebetween. The outer end portion of the screw 8 is reduced, as shown at 8a and rotatively ts and extends through an opening 2a formed in the jaw 2, the projecting end of the reduced portion 8a being rigidly (preferably removably) connected to thehub 9 of a handle carrying member I0. The handle carrying member I0 is formed with a through opening Illa 4at right angles to the screw 8 to slidably support a handle II. In the form of construction shown in Figs. 1 to 5, inclusive, the inner end portion of the screw 8 is reducedas shown at 8b and rotatably ts and extends through an opening 'Ia formed in the cross member 'I. The extended end of the reduced portion 8b is preferably formed with a diametrical u opening .to removably receive a cotter pin Tx. In the preferred arrangement, the terminating ends of the screw threads on the screw 8 provide the shoulders for the reduced ends 8a, 8b, and engage the inner sides of the jaw 2 and cross member 'I-to fixedly relate the screw 8, jaw 2, guides 5 and cross member '1, so that by grasping the handle II or member I I), this assembly which constitutes the movable member of the vise, provided the connecting element (indicated as an entirety at I2) is disengaged from the screw 8, may be freely operated inwardly and outwardly relative to the jaw 2 and base 3, as indicated by the arrows x, whereby the jaw lI may be translated with a quick movement from one position to another without rotating the screw 8.

I3 indicates as an entirety interlocking elementsbetween the base 3 and screw 8, operable to operatively connect the base 3 to the screw 8, whereby thelatter may be work piece A or release it. struction shown in Figs. 1 to 5, inclusive, the elements I 3 comprise a pair of pins 13a mounted in and depending from lthe bottom wall 3a of the base 3 at opposite sides of the screw 8 and the connecting element I2 (already referred to), the opposite end portions of which are formed with cam or. guide slots I2a into which the pins I3a project. Each slot I2a consists of a portion extending substantially parallel to the screw 8 and a portion extending substantially transversely or laterally and in the same direction as the lateral portion of the other slot I2a. The connecting element I2 consists of a plate I2 of more or less ponder-ous character disposed between the base bottom 3a and screw 8 and supported on the latter. The plate I2 is provided on its lower side and intermediate its opposite ends with a relatively wide plane surface I2b which frictionally engages with and rests on the peripheral edges of the screw threads of the screw 8, so that (a) whenthe screw 8 is rotated in either direction the connecting element I2 rolls thereon laterally in one-direction and (b) when the movable jaw I and screw 8 are being moved rectlineally from one po- In the form of conpreferably disposed midway rotated to clamp the f sition to another position, these edges slide relative to the surface I 2b. At c-ne side of the bearing surface I2b, the plate I2' is provided with a lug I2c (preferably formed integrally therewith) depending therefrom at one side of the screw 8, that side oi the lug I 2c adjacent the screw 8 being preferably of curvilinear shape and concentric to the axis of the screw and provided with screw threads I2C complementary to the threads of the screw 8 and adapted to engage the latter when the element I2 is moved laterally (fromthe dotted line position toward the left as viewed in Fig. 4) to the position shown in Figs. 4 and 5.

Figs. l, 2, 3 and 4 show the jaws I, 2, clamping a work piece A. In this position the member I2 has been moved laterally and longitudinally to move the end walls of the longitudinal portions of the slots ma into engagement with the pins I3a.. If now the screw 8 is rotated counterclockwise as viewed in Figs. 1, 2, 3 and 5 (clockwise as viewed in Fig. 4), the co-action between the threads of the screw and threads I2c will rst move the element I2 longitudinally of the screw 8 outwardly to aline the transverse portions of the slots IZd with the pins I3a and thereafter the co-action between the peripheries of the threads on the screw 8 and the bearing surface I 2b will move the element I 2 laterally (toward the right as viewed in Fig. 4) to the position shown in Fig. 5 (see dotted lines in Fig. 4), thereby disengaging the element l2 from the screw 8. With the element I2 in this latter position, the movable jaw 2 is free to move in either direction throughout the length of the screw, without rotating the latter, as limited by the engagement of the cross member 'I with the ears 3c in the outward direction and the engagement of the jaw 2 with the jaw I in the inward direction.

During translation of the jaw 2 and screw 8, independently of the connecting element I2, the latter is held stationary in its in-operative position but rests on and has sliding engagement with the threads of the screw, as the screw moves endwise, in position to be rolled laterally for connected relation therewith in the manner above set forth, By turning the screw 8 clockwise as viewed in Figs. l, 2, 3 and 5 (counter-clockwise as viewed in Fig. 4), the co-action between the bearing surface I2b and peripheries of the screw threads on the screw 8 will first move (that is, roll) the element l2 laterally (toward the left as viewed in Fig. 4) to eifect engagement of the threads VI2C' with the screw 8 and thereafter the co-action between the threads I2c and threads of the screw 8 will move the elementIE longitudinally of the screw inwardly to engage the end walls` of the longitudinal portions of the slots I2a with the pins I3a 'or the inner side of the plate I2 with the ange 3b, as shown in Figs. l, 2, 3 and '4, thereby locking the element I2 to the base 3, so that continued turning of the screw 8 will be eective to clamp the jaws I, 2, to` gether or with a workpiece between them. When the element i2 is locked to the base 3, slight outward pressure is maintained on the screw 8 during turning thereof in the jaw clamping direction until engagement with therwork is effected to prevent displacement of the pins I3a with respect to the longitudinal portions of the slots I2a. It will be observed that in operating the screw 8 to eiect movement of the element I2 into operative or irl-operative relation to the screw 8, the engagement of the pins |311 with the side walls of the slots Iza serves to guide and'V limit the movement of the element I 2. That end of the plate I2' remote from the lug I2c is thickened, as shown at I2, to provide a weight to counterbalance the weight of the lug IZc and adjacent end of the plate as well as to insure engagement of the bearing surface lfb with the screw 8 (see Figs. 4 and 5.11.). In this arrangement the entire weight, of the connecting element is supported on the screw 8 since the pins I3a loosely engage the walls of the slots without affecting the frictional relation between the element I2 and screw 8.

When found desirable the bottom wall 3a of the base 3 may be recessed, as shown at 3x (see Fig. 4) to insure clearance for the element I2. In this arrangement the bottom wall 3a may be provided with hollow bosses 3x to provide adequate seats for the pins ISa.

From the foregoing description .it will be noted that I provide between the stationary jaw of the T'ise and the feed screw for its movable jaw intertocking elements, one of which is movable and is provided with a thread to removably engage the feed screw and controlled by the rotation of the screw to engage and disengage the other element,

whereby rotation of the feed screw in the jaw clamping direction serves automatically to effect engagement of these elements and the thread on the movable element with the feed screw or the disengagement of these elements and the movable element from the feed screw.

Where the base 3 is to be supported cnthe top surface of the support B, the jaws I, 2, extend in the opposite direction with respect to the base and the connecting element I2 is related to that side of the feed screw remote from the base.

Figs. 6 and 'l illustrate a slight modification of the embodiment to simplify the construction, wherein the cross member 1 shown in Figs. 1 to 5, inclusive, is omitted and a collar 'I' is removably mounted on the inner end of the screw 8. In this form of construction the inner side of the base bottom 3a is provided with a flange 3:1': formed with openings for guiding the guides and an opening for the screw 3, the flange 3x being in the path of movement of the collar I and serving as a stop to limit the outward movement of the movable jaw 2 and parts connected thereto.

Figs. 8, 8A, 9 and 10 illustrate another modification of the invention. In these. views I', 2 indicate the jaws of the vise, the stationary jaw I being provided on a base, indicated as an entirety at I4, and the jaw 2' being provided with guides 5' slidably mounted in the base III, in the manner already set forth and 8 indicates a screw operatively connected with a handle I I'. I5 indicates as an entirety a connecting element movably disposed between the bottom wall Illa of the base I4 and the screw 8 and supportedY on the latter so as to move laterally and longitudinally thereof as already set forth. The construction of the base I4 and element I5 and operation of the latter by the screw 8 are similar to that of the base 3 and element I2, as already set forth, except that the guide pins and guide slots are reversed; that is, the pins, indicated at I5a, are carried by the element I5 (preferably formed integrally therewith) and project upwardly therefrom, whereas the guide slots, indicated at Ida', for the pins are formed in the bottom wall of the base I 4 (see particularly Fig. 10). In this arrangement the pins I5a. move through the slots Illa to guide the element I4 when operated in the manner set forthl in connection with the embodiment shown in Figs.,

1 to 5, inclusive.

- jaw Isc being mounted on a base indicated as an entirety at I6 which is secured to the support B f of the recess I6'.

by bolts I. The base I6 comprises a bottom .wall Ilia, a front depending wall IED, to Vwhich the inner jaw la: is connected, and a rear depend-w ing Wall I6c, the walls I6?) and IIic being formedv with alined openings in which guides I1 are slidably supported. The outer ends of the guides I'I are suitably secured to the outer jaw 2:13. I8 indicates a feed screw rotatably connected to the jaw 2a: similarly to the screw 8, as already set forth. The parts above described are substantially similar to like parts shown in Figs. 1 to 10, inclusive, except that the base I6 is formed on its lower side with a recess I6' the side walls of which are related to the side walls of a connecting ele- -ment I9 to guide the latter laterally of the feed screw and longitudinally thereof when operated by the screw I8. By preference the opposed faces of the walls Ib, IIc, form the front and rear walls The element I9 consists of a plate IS provided on its lower side or face with (a) a relatively wide plane surface IQb which frictionally engages with and is slidably supported on the peripheries of the threads of the screw I8 and rolls thereon when the screw is turned, as already set forth, and (b) a lug I9c at one side of the bearing surface I9b, the lug ISC being provided with screw threads complementary to the threads of the screw I8 and that end of the plate I9 remote from the lug vIllc being thickened, as shown at I9c' to counterbalance the weight of the lug. As shown in Fig. 12, the screw I8 and base I6 are so related that the element IS is movably supported within the recess I6 for guidance by the walls thereof in co-oper-ation with the rotative movement of the screw I8. Due to the employment of right hand threads on the screw IB, the left side wall of the recess I5 (as viewed in Fig. 12) is shaped to form a guide portion 20, which is parallel to the axis of the screw I8, and an off-set 20a preferably adjacent the rear wall Ic, whereas the right side wall 20h of the recess I6 between the walls Ib, IIic, is parallel to the axis of the screw I8. As shown in Fig. 11, the connecting element has a shape corresponding to that of the recess I6 except that (a) the width thereof between its end walls ISx, |233', is less than that between the walls 2|] and 2Gb, to permit lateral movement of the element I9 and (b) the length of the element is less than that of the recess between the walls I6b, |60, to permit longitudinal movement of the element I9. Figs. 11 and 12 show the element in its in-operative position, its inner side wall abutting the wall Ic, and its off-set |932" within the off-set 28a and its left side wall I9a: abutting the wall 20. If now the screw I8 is turned clockwise (as viewed in Fig. 12) the element I9 will be rolled laterally toward the right during the initial movement of the screw, such movement serving to engage the threads on the lug I9c with the adjacent threads of the screw,

further rotation of the screw I8 serving first to move the element I9 longitudinally outwardly into engagement with the wall Ib, as shown in dotted lines in Fig. 1l, and thereafter the adjustment of the outer jaw inwardly. Operation of the screw I8 counter-clockwise serves to move the element I9 longitudinally inwardly into engagement with the wall lBc and then laterally to the position shown in Fig. 11, the effect of which is to disconnect the element I9 from the screw I8, whereby the outer jaw 2r may be freely translated to and from different positions without turning the screw. As will be observed, the inner side wall of the element I9 has sliding engagement with the wall |60 during lateral movement thereof, whereas during its longitudinal movement the off-set lSr" and wall l 9:1," have sliding engagement with the walls 20, h, respectively.

Fig. 13 shows a form of construction similar to that shown in Figs. l to 4, inclusive, except that the screw threads on the feed screw 8`and connecting element 2l having tapered sides terminating in flat peripheries on which the element 2! is slidably supported and rolls. In this form of threaded elements the guide slots 22 for the pins 13x, which depend from the base 23, are disposed in parallel relation but inclined to the axis of the feed screw (parallel to the outer sides of the threads of the screw), so that when the latter is rotated in either direction to roll the element 2l laterally, it moves in a direction which is substantially the composite of the components (the transverse and longitudinal portions) of the slots |2a (Fig. 5), and accordingly the screw threaded lug on the element 2i is engaged with or disengaged from the screw according to the direction of rotation of the latter.

From the foregoing description it will be observedV that the movable jaw may be quickly moved from, any extended position into engagement with a work piece and that by turning the feed screw in work clamping direction the connecting element is moved into engagement with the feed screw whereupon the work piece may be clamped and that by turning the screw in the opposite direction the connecting element is disengaged from the screw, the work piece is released and the movable jaw is free to be moved away from the fixed jaw any desired distance.
