ADJUSTABLE vIsE.

Specification of Letters Patent.

Patented Aug. 10, 1909.

Application led `Tune 24, 1908. Serial No. 440,062.

To all whom it may concern:

Bt it known that I, FERDINAND A. PrinrER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Adjustable Vises, of

which the following is a specification, refer-` ence being had therein to the accompanyingl drawings.

This invention relates to adjustable vises, and the objectof the invention is to provide' a support for a vise of this character which will permit of the vise being adjusted vertically and about a vertical axis, and by means of which it may be locked at any.

desired point of adjustment; to provide means for holding the vise against vertical adjustment while the same is being adjusted about a vertical axis; to provide means to facilitate the vertical adjustment of the vise;

to vprovide means for adjusting the vise:

about a horizontal axis, as well as to adjust the same vertically and about a verticali axis; to provide a single Vmeans for controlling all of said adjustments; and further, to so construct the vise and its support as to render the same strong and durable, and, at the same time, of 'a minimum weight.

IVith these objects in view my invention consists in certainv novel features of construction and in certain combinations and arrangements of parts to be hereinafter described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a-vise embodying my invention; Fig. 2 is a transverse sectional view, taken on the line cc, :c of Fig. 1 and looking inthe direction of the arrows; Fig. 3 is a side elevation of a vise embodying means for facilitating the adjustment there of; Fig. 4 is a detail vie/w of the locking collar; Fig. 5 is la top'plan view of a modi lied form of support for the vise; Fig. (SlisV circular in cross section and is, in the present instance, tubular, thereby embodying the necessary strength and affording suflicient circumferential surface for the action of the clamping device, and, at the same time, maintaining the vise at a minimum weight. This stem is mounted in a suitable support which is here shown as a split sleeve 3 having

lugs

4 and 5 on the opposite'sides of the opening therein, the lug 4 having a recess adapted to receive the end of a bolt 6 which is rigidly secured therein by means of a pin 7,` and the lug 5 having an aperture 8 through which the screw-threaded end of the bolt extends. This screw-threaded end projects beyond the lug 5 and is adapted to receive a nut 9 having a handle 10 for actuating the same. Thus, by tightening the nut on the bolt, the split sleeve will be tightened about the stem 2 and the vise held `against vall movement relative to the support.v This sleeve may be of any suitable prises 4horizontal plate 11, preferably formed integral with the sleeve and adapted to be secured lto a-bench 12 by means of .bolts 13. This plate is provided at a point nearthe sleeve 3 with a depending flange 14 adapted to engage `the edge of the bench, and, to a large extent, relieve the bolts 13 of the strain imposed on the vise. Thus, it will be seen that by loosening the nut 9 the split sleeve .will spring apart, owing to the resiliency of the material of whichit is composed, a sufficient distance to permit the stem to be moved, either vertically or about a vertical axis, within the sleeve, and that, when the, vise has been adjusted to the desired position, the tightening of the nut 9 upon the bolt will clamp the sleeve tightly `about the stem 2 and rigidly secure the vise. in its adjusted position, the construction bee ing such as to vpermit of very fine adjustments of thevise.

It issometimes desirable to provide a vise with means for holding the same in its vertically adjusted position while it is being moved about a vertical axis, and, to this end,

Alo

Clo

Vbolt 28 through the same.

I have provided the stem 2 with a split collar l5 adapted to be secured thereto above the split sleeve 3 and to be clamped thereto atany desired point by means of a bolt 1G extending through an apertured lug 17 and engaging the screw-threaded recess in the lug i8. By clamping the split collar l5 Vupon the stem 2 close to the split sleeve 3 after the vise has been adjusted to the desired vertical position, it will be seen that the loosening of the split sleeve 3 Will not affect the vertical position of the vise, but will permit the same to be rotated about its vertical axis. IVhen it is not desired to use thecollar it can either be moved up close to the vise or entirely removed from the stem 2.

In Fig. 3 I have also shown means for facilitating the vertical adjustment of the vise, this'being preferably accomplished by counterweighting the vise. In the present instance, I have shown a chain 19 secured to the stem 2 near-*the lovver end thereof and extending` about suitable guides 20 secured to the lower side of the bench l2 and provided at its opposite ends with Weights 2l.

In performing certain classes of Work it.

Vis desirable that the vise should be adjusted about a horizontal axis, as Well as adjustable vertically and about a vertical axis. In order to permit of such adjustment of the vise I have provided means for adjusting the split sleeve 3 about ay horizontal axis. This I preferably accomplish by forming the sleeve 3 and the supporting` plate ll in separate pieces and providing the adjacent edges thereof with supporting

plates

22 and 23. The movable plate 22 carried by the. sleeve 3 is provided With Va cent-ral bearing aperture 24 adapted to receive a bearing screw 25, the screw-threaded port-ion of which is adapted to engage a screw-threaded aperture 26 in the fixed plate 23, carried by Ythe horizontal supporting plate ll Which is adapted to be secured to the bench. Thus, the movable plate 22, the sleeve 3 to which it is secured, and the vise Which is 'carried by the sleeve 3 may all be moved about the horizont-al axis. In order to control this horizontal movement I preferably provide the fixed plate 23 With a curved slot 2T adapted to receive asquared portion 28a of a bolt 28 which extends through the slot 27 and through

lugs

4 and 5, these lugs being, in the present instance, both provided With apertures to permit the free passage of the lIhe screwthreaded end of the bolt extends beyond the lug 5 and is adapted to receive a nut 29 having a handle 30 for actuating the same. By this arrangement of the parts, the tightening and loosening of the nut 29 on the bolt 28 controls the three movements of the vise, that is, it locks the

plates

22 and 23 against movement relatively one to the other and thereby holds the vise against movement about a horizontal axis; it clamps the split sleeve 3 tightly about the stem 2 and thus locks the vise against vertical adjustment and against movement about a vertical axis. Then it is not desired to adjust t-he vise about a horizontal axis, the supporting

plates

22 and 23 may be locked rigidly together by means of a bolt 3l extending through an aperture in the plate 23 and engaging a screw-threaded aperture in the movable plate 22, thus rigidly securing the vise against movement about a horizontal axis.

Thus, it will be seen that I have provided a vise which is capable of three distinct adjustments, that is, it may be adjusted vertically relative to its support and may be adjusted about a vertical axis or about a horizontal axis, and I have provided a sin- `gle means for controlling all of these adjustments and that I have provided means for locking the vise against nio-vement about its horizontal axis and other means for securing the same against vertical movement when it is desired to adjust the same about a vertical a Further, that I have provided meins for securing the support of the to the bench without cutting or mutilating the bench in any manner other than the forming of three apertures therein lo receive the bolts; and that I have so con- :--:tructed the vise and its support :is to render the saine strongand durable without materially increasing the .veight thereof.

I irish it to be understood that I do .not desire to be limited to the details of construction shoivn anddescribed, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, ivhat I claim as new and desire to secure by Letters Patent, is zl.
