fo /LZZ whom it may concern.-

Be it known that I, CHARLES HANrMANN, a citizen of the United States, residing at Flushing, in the county of Queens and State of New York, haveV invented certain new and useful Improvements in Bench-Vises, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention has relation to vises such as are employed by mechanics and intended to hold articles or materials while they are being worked upon. These vises are usually attached to some fixed support, as a bench, and they are ordinarily known as "bench-vises. Of these bench-vises there are many varieties suitable for holding different kinds of work and operative in different ways, and it is to a variety now come to be commonly known as my invention isvparticularly directed. The quick-action or rapid-transit vises are such as -permit of the movable head being adjusted rapidly back and forth without the necessity of depending upon the screw or independently of the screw when the latter is out of. engagement with the means by or through which it causes the head to move back and forth.

The principal object of my invention is to provide or produce a quick-action or rapidtransitbench-vise wherein the grip of the screw is effected or relieved by asimple and comparatively slight turning ofthe screw-shaft itself, wherein the parts are few and simple and easy of construction and easy to mount in place, and wherein the working parts are durable and substantial, reliable and efficient in action, and not liable to get out of order.

To accomplish all of the foregoing objects and to secure other and further advantages in the matters of construction, operation, application, and use, my improvements involve certain novel and useful peculiarities of construction, relative arrangements or combinations of parts, and princi ples of operation, all of which will be herein first fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, I have shown my improvements as applied in connection with a particular form of bench-vise which is ordinarily called a cabinet makers vise or Woodworkers vise; but it should be understood that this selection is only for convenience of illustration and that my improvements are equally applicable in connection with any other variety of bench-vise.

Figure l is a section and elevation of one form of a vise having my improvements applied thereto, the view being taken on a plane through the axis of the shaft or vise-screw and the working parts being shown in the position which they occupy when clamping any piece of work or when the movable vise-head is forced up close against the stationary head. Fig. Q is a cross-section and elevation on a plane through line t a of Fig. l and looking in the direction of the adjacent arrows. Fig. 3 is a cross-section and elevation on a plane through line b of Fig. I and looking in the direction of the adjacent arrows, but omitting the screw-shaft and screw. Fig. 4L is a crosssection and elevation on a plane through line c c of Fig. 'l and looking in the direction of the adjacent arrows. Fig. 5 is a side elevation and partial sectional view of the screw as it appears when dismounted or disconnected from the shaft and other parts, this view being enlarged beyond the previous views.

In all the figures like letters of reference wherever they occur indicate corresponding parts.

A is the front or movable head of the vise, which is intended to travel back and forth and to operate in connection with the other head B, which is stationary and usually constitutes a portion of the body of the vise.

C represents a fragment of a bench or other object upon which the vise may be mounted in any suitable way, the location of the visebodyin respect to this bench, as shown in the drawings, being merely that adopted in connection with cabinet-makers or woodworkers vises.

D is the main portion of the body of the vise, which carries the stationary head and accommodates the slide-bar, which carries the movable head. The slide-bar (represented at E) is fitted to slide easily, but with considerable accuracy, in the body of the vise, carrying with it the movable head and screw-shaft and its handle.` On the inner side of the slide-bar is a rack, (represented at 62,) the same being formed with the slide-bar or applied thereto in asubstantial manner and being fitted to engage with the screw by which the slide-bar is to be'moved.

IOO

F is the screw, which is made amply strong and which is calculated to be turned by the screw-shaft Gr. The shaft G is slotted or channeled or key-seated, as at e, and a key f applied in the screw F permits the shaftG to slide back and forth within the screw, but compels the screw to turn whenever the shaft is turned.

H is a suitable head for the shaft, the same being fixed on the outer end of the shaft in some substantial manner or by some su bstantial means, and in this the handle or lever H is mounted, as is usual in vises.

When the screw F is in engagement with the rack d, the turning of the shaft Gr, and through it the screw F, will effect the retraction or advancement of the slide-bar E with respect to the body of the vise, and therefore open or close the vise-jaws A and B. According to my invention'the screw and the shaft are arranged to be dropped down or the screw, in other words, to be carried out of its position for engagement with the rack, and when the rack and the screw are out of engagement the bar E, carrying the head A, may be moved back and forth rapidly and without depending on the slow turning of the screw.

That the screw may be thrown into engagement with its rack or permitted to move out of said engagement by the simple turning of the screw-shaft, Iprovidethe shaft-head with one, two, or more recesses, as at g, the same having an inclined side, so that the turning of the screw-shaft in one direction will cause the head and adjacent end of the screw-shaft to rise or be forced up on a correspondingly-inclined or other suitable projection, as t, which is aflixed to or forms part of theslidebar. The screw F is similarly recessed, as at g g, and these recessed portions of the screw ride upon a suitable block or other projection, as L, applied to the lower portion of the vise-body. The notches or recesses g and g are of depth suficient so that when the screw drops down or when it is in its lowermost position it is entirely free from engagement with the rack, and the slide-bar is then free to be moved out or in rapidly and as occasion may require.

The screw is located between two abutments, as at I and K, iiXed with respect to the body of the vise, and these, as also the front wall of the slide-bar, are provided with openings, as o 0, sufficient to enable the screw-shaft to rise and fall within them as may be necessary. A collar on the screw-shaft (shown at L) compels the shaft to travel with the slide-bar.

When the handle H or the shaft-head H is turned in the direction to screw up the movable vise-head, the screw turns with it and is forced up to engaging position by the blocks or projections 7L t'. Then on further turning of the screw-shaft and screw the slidebar is moved by the screw, the adjacent end of the screw then bearing against the abutment K. This bearing is ordinarily sufficient to prevent the screw from dropping out of engagement with the rack as the shaft is further turned: but I find it desirable to provide the screw with a slight projection, as at z', and to recess the abutment K, as at 7c, suflciently to take this projection, so that when the screw is elevated to its engaging position and commences to move the rack and the slide-bar connected therewith the projection 'a' will be forced into this recess 7c in the abutment K, and the, screw will thus be prevented from descending until it is turned in the opposite direction. On turning the screw-shaft in the opposite direction the screw will by its contact with the rack be carried forward enough to relieve the projecting portion c' from the recess 7c, and as soon as the notches g g reach positions over the respective projections /L /t the screw and its shaft will drop down and the screw be disengaged from the rack.

From'the foregoing it will be readily understood that in order to tighten the vise by use of the screw it is only necessary to turn the shaft in the proper direction and that to disengage the parts so that the slide-bar will be free to be moved back and forth without turning the screw it is only necessary to turn the screw-shaft in the direction usual for releasing the work.

One notch g or g will be sufficient, but would necessitate a complete revolution of the vise-shaft in order to bring the parts into working engagement or to release them. By employing the notches in pairs, as indicated,

IOO

manifestly only one-half turn of the screwshaft is all that will be necessary to effect the desired engagement or disengagement, and if it should be desired more of these notches may be employed; but the `half-turn of the screw-shaft is deemed none too extensive a movement to effect the desired results.

The threads of the screw for the length of the recess gf are preferably blunted or cut away, as indicated in Fig. 5, so that they will ride easily on the projection 7L' and without cutting into the latter, and the height of projection i is made to compensate for this cutting away of the screw, so that the screw and its shaft will rise and fall parallel with the rack.

The devices being constructed and arranged substantially in accordance with the foregoing explanations will be found to admirably answer all the purposes or objects of the invention hereinbefore alluded to.

Having now fully described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-

1. In a bench-vise having jaws, the combination with the slide-bar carrying the movable head or jaw, of a screw-rack in said bar, a screw for engagement with the rack and a shaft for turning the screw, the screw and its IIO shaft or permit them to drop, substantially shaft being arranged to be raised and lowered by turning the shaft, substantially in the manner and for the purposes set forth.

2. In a bench-vise having jaws, the combination with the screw-shaft and screw mounted and keyed to each other so that one may move within the other, the head of the shaft and the screw being notched as explained, and the projections arranged to elevate the screw and as and for the purposes set forth.

3. The combination with the vise-jaws and a screw notched as explained, of the shaft for turning said' screw and made movable therein, and abutments connected with the vise-body and arranged to permit the screw and its shaft to rise and fall, substantially as set forth.

4. The combination of the vise,- jaws, the screw', the screw-rack, the screw-shaft moving longitudinally through the screw, and the abutments, the screw being provided with a projection on one end and the adjacent abutment being recessed to receive this projection, substantially as shown and described.

5. ln a bench-vise having jaws, the screw notched as explained, a projection on the visebody for entering said notch and a shaft for turning the screw, the threads of the screw `being cut away to ride on the top of the projection,the parts being combined and arranged substantially as set forth.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
