Application filed October 27, 1913. Serial No. 797,613.`

To all whom it may concern:

Be it known that I, JOHN R. LONG, citizen of the United States, residino' at Akron, in the county of Summit and tate of Ohio, have invented certain new and usefullmprovements in Bench-Vises, of which the following is a specification. j

This invention relates to yan improvement in bench vises, and the invention ,consists in the construction and combination of parts Substantially as shown and described and particularly pointed out in the claims.

` In the accompanying drawings, F igurel is a side elevation of the vise shownwith the jaws open. Fig. 2 is a rear end elevation,

and Fig. 3 is a front elevation with the ope`r-` ating handle omitted. Fig. 4, sheet 2, is a side elevation partly in section with the jaws closed on an object therein. Fig. 5 is a cross section on line 5 5, Fig. v4. j. r l.

The present invention has to do more esn pecially with certain important Vdetails of construction relating to the automatic lock-` ing of the vise when in use and the construcupon the vise shown and claimed in my application tiled February 10,1913 and bear! ing Ser. No. 747,214. The main parts are substantially the same in both cases fand.

comprise abase A, adapted to be rmly fixed upon a bench, block or other.V support, a main or lixed jaw Crotatably engaged on said base, a slidable or movable jawy D, supporting bar B and yoke E. The said base is substantially dish shaped so as to be open on its bottom to place the pivot screw 2 in positio-n for engagement of .the `friction member or disk 3 thereunder andwiththe shank of jaw C, the said shank having ascrewthread ed hole from beneath penetrated by said screwand which serves to hold the said jaw said base to protect the same from injury,` i

the said base being of cast metal and liable to be cracked orv broken by a blow directly thereon. The said Cheeks 6 have straight specification of Letter; raient.

. for saidbolt `9. -The supporting bar B `ttor 15atented the said shank 7 of jaw C, audit `follows through`this construction that when said jaw islrotated on base Athe said friction member 3 is rotated therewith. i

screw 2 shall be made sutliciently tight to octia, 15914;

parallel wallsfitting closely upon or` against i merely hold the jaw C from being rotated,

and suoli rotation is only intended to bring the tool into convenient position for use and according to the conditions about it for use. Then whenfp'ositioned as desired the actual g locking against rotationduring use is. providedfor through the means at the heel'8 of` the shank 7on jawmember CJ These imeans comprise a transversebolt or screw 9 through the bifurcated or openl slotted upwardextension 1() ofthe jaw shankat the end thereof and which isprovided with ati'ansverse hole jaw D Iand yoke Elias a flaring transversek said bar has 'a limited lengthwise` Vsliding movement on said bolt 9 at itsrear and on its spindle 12` at lthe front, thus serving to lock said jaws on the work after the jaw D has n recessfol opening in itslarger and outer end Q i which is traversedby bolt 9 and which serves as a rest forfthe saidbar in said recess, and tion oi the bar which supports the slidable jaw and the yoke, and is an Vimpro-vement been moved into engaging or clamping posii i tion, say as seenin 4. Such lengthwise movement or adjustmentjof bar B is by means' of the screw Swhich engages inthe internally threaded stem 12 projecting through acorresponding bore inthe base of l jaw C. The said screw has a head carryingzf;

therein andby which avery limited length- ,the operating rod" or., handle 14` slidable wise tightening movementof jbar'B is pro- 1 vided for tol take up any slack or looseness after the jaw D and yoke Ehave been moved [upby hand to engaging` position.` Such movement or handling isxin part provided forby the hand knobs 17 on the side of the yoke, adapted for both right and lefthanded` j persons.. Thesaidparts and E are operativelyconnected by'vthe set -screw 17 enter` loo ingapside recess in said jaw. By gripping one of said knobs the jaw Dcanbe moved back and forth through the movement of the yoke... This done and the jaw vmoved upto theflwork as in Fig. 4, the tightening of the parts isefected through screw S. I nciden:l

` tally this also locks the bar B` against rotation on` pivot 2 because it tends-to'tilt the y heel 8 upward and to depress the correspondi 66 `In operation it `1s intended that the pivot j j ling end of bar B by ythe opposite effect upon4 jaw D. Actual locking between the parts as aga-inst rotation horizontal-ly onthe base occurs through a set screw 18 engagingv in a j B against rotation. The said thimble bears e on collar 5 and the end of bar B bears on the head of set screw 18 in itstla-ttened portion which comes' slightly above the. top` of the bottom of the slotin `or betweenI the eXtensions 10. The said screw enables me to make reined adjustments to` take up possible wear at thisfpoint as well asto provide an exposed vbearing for the thimble 19, but when the jaws are released tensionl on screw 18 also is relieved.

vA further material improvement in the present vise over the above application resides inthe shape-of the top bearing surface of bar B for the yoke E. In the above mentioned lapplication the said bar is shown as 'y being fiat transversely on its top but in the present instance I have made the said surface of inverted V` shape, thus providing a riding edge 20; for the aw D which has correspondingly inclined sides guided thereon and this serves also to keep the top of the 'said bar clear from foreign accumulations;

`A further improvement is found in the clip 22 adapted to be engaged over the rear end of bar B and to seat at its sides upon the top edges of the upwardgextensions 10 on the shank of jaw C. The said edges are straightand correspond to the side edges of the clip resting thereon, and a lifting screw j 28, engages throughl the top of said clip and into" a threaded holein the end of bar B. `W hen the said screw is tightened it has a lifting action or eect on bar B and to this j extent relieves down pressure on the screw 18 and 'enables the vise -to be rotated on its base without releasing the stock gripped "thereincby turning the screw S, as would be'necessary if the said clip were not employed. Releasingy screw S would also release'4 the stock, but by means of said clip the stock can be kept in the vise and the vise rotated. lThe yoke E is flared from rear to front to engage with locking effect on both barB and jaw D, and the bottom b of bar Bis inclined upward from rear to front andthe back d ofjaw D is at a somewhat greater inclination vrearward and downwardl according to the top flare in said yoke sovthat when the said yoke and jaw are movedto clamping'position the jaw will'be veifectually locked and cannot slide away i f under pressure. l By making the inclined edge Z9 less than 15y degrees as show-n and 'placing the yoke in a more or less tilted relationthis locking is made very effective.

f The said cheeks 6 represent the top exposed sides of the hub on the said' friction member 3, and the said hub 1s circular or round and fits in the circular opening in the base soas to be rotatable therein, and the said collar 5, a sheet metal part, preferably ts Vsnugly about its inner edge upon said hub -above base B. The jaw D has a collar or ju'stments.

The construction of yoke E and the bar B and jaw D are such that when the said jaw is released or loosened from work and drawn back the yoke E will not only become loose Y alsol but drop down and rest on the top edge of the shank 7 of jaw C. The heavy transverse bolt 9 through the ears 10 of the outer jaw member C serves more especially as a back stop for the jaw D. Of course the vise `can be used without the clip Q2, but said.

is released from the jaws.

clip is very useful when the work is heavy and there is need of swinging the vise around in either direction before the work fsaid clip takes the pressure off of the bolt L19 suiiiciently to enable the vise to be rotated on base A. By the term bolt I mean the two parts 18 and 19, because a single solid bolt will serve my purpose but I use a two-part bolt by preference so as to have an. adjustable portion to take up wear thereon.

lVhat I claim is:

1. In vises, a base of substantially dish shape having a flat top and a down flange about its edge and an opening in its center7 a friction member inserted from beneath vthrough said opening and bearing against the bottom of said base and provided with cheek portions projecting through said opening and provided with a channel between them7 in combination with a jaw having a shank seated in said channel between said cheeks and a screw through said friction member and engaged in said shank and adapted to lock said parts together upon said base.

2. A vise having a base and a friction member rotatable in said base having a hub, an outer jaw having a shank fixed in said hub, a bar supported at one end on the rear end of said shank and provided with a spindie engaged through the base of said jaw, an inner jaw slidably mounted on said bar and a yoke connecting said inner jaw operatively with said bar.

8. A vise having a base, a friction memf ber rotatably mounted in said base and provided with a walled channel exposed above the base, an outer jaw having a tapered shank locked in said channel through said `friction member, in combination with an In that case thev inner jaw, a bar on which said inner jaw is sldably mounted and supported at one end on an upward extension of said shank and at the other end in the base of said outer jaw, means to draw said bar lengthwise to tightened position and a bolt under the heel of said bar bearing down upon the said base and adapted to lock the vise against rotation when it is engaged upon an object.

4. In a vise, an outerjaw having a tapered shank and an upturned outer eX- tremity and a base on which said jaw is rotatably mounted, a bar having one end supported on said extremity and provided with a spindle at the other end projected through the base of the jaw and internally threaded, a rotatable tightening screw engaged in said spindle and a bolt in the rear of said shank adapted t0 lock said bar against rotation on said base, and an inner jaw slidably confined upon said bar.

5. A vise as described having an outer jaw member having a shank provided with an upturned divided outer end, a jaw supporting bar mounted at both ends on said jaw member and removably supported thereon, an inner jaw adjustably mounted on said bar and a yoke about said inner jaw confining the same operatively on said bar, in combination with a base supporting said jaw member, a locking bolt inthe heel of said bar bearing upon said base and a screw in said bolt to take up wear.y

6. A vise having a bar and an outer jaw Copies of this patent may be obtained for adjustably mounted thereon and provided with a split upwardly turned end and a transverse bolt in Said end, in combination with a bar mounted on said bolt and having a spindle projected into the base of said jaw, a clip seated over the end of said bar and resting at its sides on the sides of said "upturned end and a screw through said having a substantially V-shaped channel in its bottom edge, slidably mounted on said inverted V-'shaped top edge, and a yoke operatively confining said parts together.

8. A vise vof the kind described having an outer jaw, and a suitable support onwhich said jaw is slidable, and a yoke operatively confining said parts together, said jaw being provided with a bead about the neck thereof adapted to shed ilin s from vits sides and prevent the same rom falling upon said support and yoke.
