E KM l ATTORNEY Patented July 1, 1941 UNITED TS TENT Application December 8, 1938, Serial N0. 244,527 In Austria December 9, 1937 (Cl. Sli-60) 5 Claims.

Parallel vises are already known in which the jaws that grip the piece of work cooperate, during the clamping operation, with a pivoted or rocking member accommodated between the clamping device and the jaw carrier (for instance a rocker arm, eccentric or tilting member), and causing said jaws to move downwards to the vise bed, in order to grip the piece of work safely in the vise. In such vises, the downward movement of the jaws towards the vise bed always involves a movement of the jaws relatively to the jaw carriers which lie in the principal direction of movement of the jaws, i. e. in the longitudinal direction of the vise bed, and are directed towards each other or in opposite directions. Rocking movements of the indivi-dual jaws are frequently added to the said relative movements. All these additional movements of the jaws relatively to the jaw carriers are detrimental when a piece of work is being clamped.

'When machining or working a piece oi work, it is often important to use a vise having one jaw safely secured in the direction of the axis of the vise bed, in order to have a iixed stop for the piece of work which allows of working same at an exact predetermined distance from such a stop. The known vises the jaws of which eiiect a downward movement towards the vise bed when clamping, owing to the above mentioned additional movements, cannot provide such a stop for the piece of work which is a further essential disadvantage of such designs.

The invention has the purpose of providing vises with, in the moment of clamping, downwardly moving jaws, in which rocking and axial movements of the jaws relatively to the jaw carriers and the involved detrimental effects are eliminated. rFhe invention chiefly consists in that the jaws are movable on the jaw carriers, at right angles to the vise bed and parallel to each other. To facilitate such movement balls or rollers may be inserted between the jaws and jaw carriers. If itis intended to provide the novel vise with a jaw secured in the direction of theA vise spindle, such jaw, accor-ding to the present invention, is mounted on a carrier firmly secured to the vise bed, so that it may move at right angles to the bed and parallel to the other jaw, while the said other jaw is movable at right angles to the bed on a carrier, said carrier being naling the threaded spindle 3. A plate 4 formed as a guide is firmly secured to the pedestal 2 and base plate I; the remote end of the said plate d is held by the support 5 and carries the jaw carrier The jaw carrier 6 carries a framelike body or jaw holder 1 to which are secured the jaws 9 provided with a lining 3. The body l and the jaw 9 are supported on the jaw carrier 6 by means of balls or rollers I! moving along vertical guides in the carrier 6. The frame-like body i is further guided by the supports 5 and 5 iirmly secured to the base plate. This guide may also be improved by balls or rollers. The other jaw il is also mounted on a frame-like body or jaw hol-der l2 and is supported by a carrier I3 movable in the longitudinal direction of the plate l as a slide. i4 is the lining of the movable jaw. The mounting of the jaw il and the frame-like body i2 on the slide-like carrier i3 is similar to that of the iixed jaw Si; balls or rollers l5 may be interposed to cooperate with vertical guides of the carrier i3: The screw spindle 3 has its abutment in a slide ill in which the said spindle is mounted rotatably and secured by a flange il. The slide i6, as compared with the stationary carrier 6 and the support 5, is somewhat movable in the longitudinal direction of the vise bed; this movement is limited by an adjustable stop, formed by set-screws i8 anchored in the support 'e'. A tilting member I9 is interposed between the slide IS and a shoulder 2li of the frame-like body l' so that the action is carried on to the jaw 9. The spindle 3 is spun into a further slide 2l which may be moved longitudinally by turning the spindle. This slide serves for longitudinally adjusting the movable jaw Il. Its action is also transmitted by a tilting member 22 cooperating with a shoulder 23 of the frame-like body l2 of the movable jaw il. movement of the tilting body or member, the slide 2i and the slide-like carrier E3 must be movable relatively to each other. This relative movement is limited by an adjustable stop formed by screws 2li anchored in plates 39 secured to the jaw carrier I3. 3l are guide rails which are held by screws (not shown) anchored in the carrier i3 against the path of the carrier on the slide 2l; these guides serve for eliminating any play between the carrier i3 and slide 2i. Both the stationary jaw and the jaw movable by means of the screw spindle, provided no piece of work is between them, must be secured in their end position more distant from the vise bed. Coiled springs serve for this purpose; they are arranged partially in horizontal, partially in vertical direction and cooperate with the assembly carrying the jaws. The carrier 'l of the nxed `jaw 9 for instance is pressed upwards by vertical coiled springs while horizontal springs 26 cause the slide I6 to give way laterally and thereby likewise In order to allow of a carriers and towards said bed upon exertion of pressure on said jaw members.

3. In a vise, a bed having longitudinal guides,

jaw members for clamping piecesv of work, jaw carriers movably connected with said jaw members and comprising guide means guiding the relative movement of said carriers and jaw memf bers at a right angle with respect to said bed, one

slide 2l, during the said movement, carries along with it the frame-like body l2 and the jaw' Il as well as the slide-like jaw carrier I3. The movable jaw I4 and the corresponding V`carrying assembly advance towards the stationary jaw 9, until the piece of work accommodated between the jaws is gripped by the said jaws at both ends.

The pressure generated between the piece of` work and the jaws causes the tilting members I9 and 22 to swing whereby the jaws are drawn downwards along the vertical guides of their carriers. vertical springs 25, 2l, and 23 and the horizontal springs -26 and 29 are compressed. When the vise is reopened, the jaws urged by the before mentioned springs ar'e immediately movedinto their upper end position remote from the vise bed and the vise is thus again suitable to receive another piece of work.
