Application filed November Ton/ZZ whom` tt 'may co'ncera: p

le lt known that Lpllinnonr WYIL'D, a citizen of Germany, reeiding `at Los' Angeles,`

in the county of ioe Angeles and State of California, hare in'vented a new and useful l-l'and Vise, of which the following' is a epe *ilication This invention relates to devices used for holding small articles in the hand.

Oneiof the objects of this invention ie to provide a hand-Visio in which thejaw faces can always be maintained parallel to each Fig. 1 ie a Sideelevation of a hand Viec embodying this invention.

Fig. 2 is a side elevation of the device of Fig. 1, having the aws adjusted to positione further apart than in Fig. 1.

Figz. 3 is a' fragmentary eide elevation of the rcar end of a hand Vice having a slightly modified form of spring member.

The jaw faces 4; in Flg. 1 are adjnsted so as to approach each other rather closely, while the jaw faces in Fig. 2 are adjusted to position further apart, butin both illus' trat-ions it can be noted that the 'faces are disposed parallel to each other. i

ll/'Lirlr or material Vcan be held much moro firmljT in a Vise if the aws are arrangedeo as to bring` the jaw-faces parallel to each V other than if the jaw faces were'allowed to change their operative relation in regard-to the faces when approaching to engage work or material. If merely oppositely dieposed edges of the opposite awmember of a Vise come in contact with work or material, the material is liable to be cut, or at least'is liable to Show inarks more pronounced than if thejaws set or engage more evenly.

In the drawing, the two jaw members and 6 are united by a common spring' mem-`V ber 7 at their rear ends. Spring and. jaw members may be integral, since preferably of steel throughout, especially in small tools,

but, Vof course, .larger tools may have the springseecnred to the rear ende of` jawi'neinbere. The aws proper, that is, the jaw i faccs or the material 'close to the jaw faces may bei of good steel, ieusceptible to 4 teinpering, while [the larger body portions` of the jaw menibenmay be of common'or` soft steel. These and other niinor details arenot brought out in the drawing, but, since commonly lznown in .the art, l *'ish it understood that I do 'not limit inj'eelf to the particular Structure shown in the drawing'but that such minor details-may be applied within the ecope of fthe'claiins, Such ae .using `wing-he`ade instead of the round lnnrled heade shown `lin the drawing.

The screw `8 paseee loosely "through the jaw-member while engagzing vwithin the.

jaw member 6. The end 10 tie shown tl'n'ead'-- ed for this purpose. 'Of course, an extra nut may be applied to the one aw member instead of hz'wing vthe one jaw niember threaded to engage the ecrew ae illnetrated in the drawing', vthe applyingof extra loose nuts being well known in the art, an illastration of this is deen'ied iinnecessai'y. `rl`he scre-w 8 is preferably` shouldered, as indi-i` cated at 9, to seat on the cute-ide of the one jaw member, and to reduce thefriction, by

havino' the shouldered face as sinallas Jossible in proper proportion to the device.

A second screw ll is provided -for preseingl the rear ends of the aw members apart. In the drawing, the screw io threaded as indicated at 12 to iirinljy' but turnablj7 en' gage with one of the jaw men'ibere, while the free end 13 abuts against the opposite jaw' member. j I I As illustrated in the drawing, the set screw 8 is adjusted against the tension of the spring 7, while the set-ecrew ll is merely Set against the rear ends of the jaw members, in order to bring the aw faceeit parallel to each other. f w 4 Bjfireleasing the set screw 8 to a suitable extent, the set screw 11 can eaeily be 'ad' justed to force the rear ende of the jaw members accordingly to again bring the' jaw faces 4-. into positions pa'allel to each other, as illustrated in Pig. 2. i

The range of the adjust-ability, of course, depends largely on lthe lexibility `of the Spring portion of the device.l i

The spring, on the otherhand', can eaeilyv be inadeof Various forms, toallow an adjusting to a great entent. slightly modified form of spring is illustrated in Fig. 3, as indicated at 11k. The rearends of jaw members are indicated at 15 and 16 in this modified form. H the Springs are "made separate, they are suitably secured or applied to the rear-ends ot' the jaw members in any manner well known in the art.

Having thus desoribed my invention, I claim:

1. In ahand vise, jaw members having their engagng faces disposed oppositeeach other with their body portions `extending rearwardly, a spring conneoting the rear terminations of the sald body portions of the members, a set screw turnably disposed i through one jaw member and having threaded engagement with the opposite jaw member, and another set sorew having threaded engagement with one jaw member and having its free termination abutting against the opposite jaw member.

2. In a hand Vise, jaw members, a spring conneoting the rear terminations of the jaw members, a set screw disposed near the engaging faces of the jaw -member having threaded engagement with one jaw membei` and having a shonlder engagement over the outside of the other jaw member for drawing the two jaw members together, and another'set serew disposed between the firstnamed set screw and the rear terminations of the jaw members and adapted to press thetwo jaw members apart.

3. In a hand vVise, jaw members having spring interconnection at their rear termina tion, and contrary acting set sorews for drawing the jaw members together at one point while forcing the jaw members apart at another point so as to control the eng-aging faces of the jaw members in a desired relation to each other.

In testimony that I claim the oregoing as my invention I have signed my name'in the presence of two subscribing witnesses.V
