VISE.

SPECIFICATION forming part of Letters Patent No. 733,044, dated July '7, 1903.

Application filed July 7, 1902. Serial No. 114,688. (No model.)

To aZZ-whom it may concern.-

Be it known that I, J OHANNES HUBNER, a subject of the Emperor of Germany, residing at Hermsdorf, Silesia, Germany, have in- I vented certain new and useful Improvements I ing, boring, or drilling machines, lathes of all kinds, and the like, for the purpose of seflcurely clamping the work-piece to the ma chine while being operated upon; and the object of the invention is to provide a clamping means which will securely clamp the workpiece.

With this object in view the invention consists in the combination of parts hereinafter described, and specificallyset forth in the appended claim.

In order to make the invention more readily understood, I will now describe it with reference to the accompanying sheet of drawings, of which- Figure 1 represents a vertical sectional elevation, and Fig. 2 a plan view, of the device. Fig. 3 shows a key to actuate the device.

a designates a block, preferably of castiron, with a trough-shaped hollow b and an elongated slot 0 for receiving a bolt, by means of which the casting can be adjustably secured upon the machine or lathe. At one end the block is slantingly planed OE and dovetailed, as at d. Into this dovetailed end fits a correspondingly-dovetailed block or jaw f, with attached steel biting-face g. A cylindrical hole is bored parallel to the dovetail slant, having its longitudinal axis on the center line of the meeting surfaces of the two blocks a and f. The semicylindrical face of the block a is provided with a screw-thread resembling a toothed rack, while the corresponding face of the jawfis provided with two curved projections or ribs h and 1'. Into the cylindrical bore fits a screw-cylinder it, provided with an outer thread adapted to mesh with the threads on the block a, and also with two circumferential grooves Z'm, adapted to receive the ribs h t. Into the top end of the screw-cylinder is sunk a square hole a for receiving the key 0. (Shown in Fig. 3.)

After the various parts are assembled the key is inserted into the hole n and is turned one way or the other, causing the screw-cylinder to turn correspondingly, with the effect of raising or lowering vertically the jawf and at the same time advancing 'it horizon- 6o tally toward or retracting it from a given point.

It is obvious that preferably two of these devices are used in conjunction, in which case they have to be arranged on the machine facing each other, forming a vise, the two jaws of which may be set at the start at varying'distancesfrom each other.

I have found that a suitable relation of horizontal to vertical movement is as one to three-4. a, to each unit of horizontal movement three units of vertical movement are consumed. The force pressing down the work-piece clamped between such a device and a rigid rest or between two such devices, 7 5

owing to the combined movements, is relatively very great, and a lifting of the clamped object is practically impossible.

What I claim,and desire to secure by Letters Patent, is-

In a clamping device, the combination of a block, means for adjustably securing the said block to a suitable machine part, an inclineddovetail guideway at one end of the said block, a jaw, a gripping-face attached to the said jaw, a dovetail rib at one end of the said jaw adapted to engage the dovetail way in the block, a screw-cylinder, adapted to occupy a bore sunk partly into the said block and partly into the said jaw, parallel 0 to the dovetail guideway, semicylindrical screw-threads on the inner block end adapted to mesh with the said screw-cylinder, curved ribs on the inner jaw end adapted to engage corresponding circumferential grooves on said screw-cylinder, and means for turning the said screw-cylinder one way or. the other,

the parts being constructed, arranged and cooperating, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

JOI-IANNES I-IUBNER.
