Application filed February 17, 1920'. Serial No. 359,4?7.

To all whom it may concern:

Be it known that I, GUNNAR ELIAS Gas- I sEL, a citizen of the Kingdom of Sweden, res ding at Stockholm, Sweden, have Invented much as in clamping work the; final tightening of the movable jaw only and releasing work the initial opening movement only must be efiected by means of a screw mech anism. v The principal feature of the invention consists in providing the'mov'able jaw with a bolt rotatably mounted therein, a coupling mechanism' being provided between said bolt and a screw said coupling'mechanism normally permitting free movement of the bolt but looking the bolt to the screw for the purpose of effecting the final tightening of the movable jaw as soon as the bolt is rotated.

- In the accompanying drawing, a bench I vise embodying this invention is illustrated.

Figure 1 is a longitudinal section of the vise and Fig. 2 isa cross section thereof:

With reference to the" drawing, the nuvise, and 2 is the movable jaw thereof. The

movable aw is slidably mounted, as by means of a sleeve-shaped portion 3 ina corresponding boring in the fixed jaw. Rotatably but not slidably mounted in the lower 1 portion of the jaw 2 and extending through the sleeve 3 thereof is a bolt 5 the part of which extends beyond the front of the jaw V I the left in Fig.1, while the screw 15 will i 2 and carries a handle 6 of well known construction. The inner end of the bolt 5 engages loosely in two sleeve shaped members 7 8, the former of said members being slid-I ably mounted in an extension of the boring 4 has a reduced diameter, while the sleeve 8 is slidably mounted within the sleeve-7.

Formed in the part of the bolt 5 engaging said sleeve-shaped members 7, 8 is a plurality of longitudinally extending slots 9 (in Fig. 2 three such slots are shown). Each of said slots contains a double wedge 10 supported by a spring 11. resting on the bottom Specification of Letters Patent.

This invention relates to a parallel bench meral 1 designates the fixed jaw of the bench PARALLEL BEnon-vIsE.

of the corresponding slot. One inclined'sun face 12 0f each wedgeis adapted to engage a conical recess formed'in the sleevei7; while the other inclined surface 13 ofeachwedge isadapted to engage a similar recess formed ln'the sleeve8f The double :wedges 10 engage said recesses in such away as to prevent relative rotation of the 'members5, 7, 8,

v as will'be seen: from Fig-2,. which shows the 1 engagement of the wedges in the sleeve- 8. Inserted n the end of the sleeve 7 remote from the bolt 5 is a screw threaded plugffl-Lii forminga bottom of said sleeve while the l sleeve 8 1s-formed with a-bottommade integral with the sleeve; A threaded opening. 7o

in the plug 14 is engaged by a screw-15, ex-

:tending through the plug 14: and bearing I with its inner end against the bottom of the sleeve 8. The screw 15. is made integral with a'screw 16 having a greater pitch than that of the screw-15 and engaging ina-fixed nut 17, the screw carrying; outside thereof a head 4- f a I ,The bench vise described operates-as 011,

lowsz Assuming the aws are intheposition shownin Fig. 1 and wo'rkis to be introduced therebetween, the jaw 2-l with the bolt 5 i's first moved outwardlywhich may beelfected without anydifficultyaslthe angle of each f wedge-10"i's so adjusted thatthe wedgeizwill s not prevent the displacement of the'bolt 5.

After the jaws are, thus removed sufliciently to permlt ,the insertion of the work, the

latter is placed betweenthe jaws whereupon .the distance between the jawsis decreased bylmoving he-1W2 i rd y ll, oth jaws will contact with the work. The bolt '5 is then turned to the right by means of the handle 6. The wedges 10 will in this movement take the sleeves 7 and 8 with them. The sleeve 7 isthereby turned about thescrew 15 and'moves, consequently, to

prevent any displacementof the sleeve 8. It is obvious that the conical recessesof the sleeves 7 and 8 due to the said movement will draw nearer to one another and will as a result come into contact with the wedge surfaces 12 and 13, respectively, thereby pressing the wedgesinwardly toward the bottom of the corresponding'slot 9 in the 8, the screw 15 will be caused to turn with the bolt'5, and upon the continued turning of the bolt the screw will move outwardly (to the left in Fig. 1), due to the engagement of the threads 16 in the nut 17. The bolt 5 with the movable jaw 2 is thereby moved toward the fixed jaw 1, till the work vis rigidly clamped between the jawsiso as to prevent any further relative movement i of the jaws. g 1

When the work is to be released, the bolt 5 is'fir'st turned to the left. The bolt 5 will 'thentake the sleeves 7 and8 together with the screw15, 1-6 with it, till the head 18 of the latter strikes the nut 1'7, after which the sleeve 7 will'be turned inwardly (to the right) 011 the screw-threads .15 thereby effecting a separation offthe sleeves 7 and c by turning the bolt 5, while the main part of the'movements of the movable jaw may be effected by directly displacing thejaw bythe hand which will, of course, result in a considerable saving of time in operating the vise;

llaving thus described my invention,
