8 Claims.

This invention relates to work holders, and more particularly to a vise having a bed plate on which are mounted a fixed j aw and a rectilinearly movable adjustable jaw. The invention is shown as applied to asine vise and it has certain special advantages in that connection, but it may be'applied to work holders used on machine tools and the like.- l I One of the objects of the invention is to provide a vise in which the work piece held in place between the jaws may be positioned at will in an accurate manner in any of a number of angles relatively to the longitudinal axis of the vise in order to facilitate operations of tools upon'the clamped work piece.

Another object is to provide a simple device adapted to be associated with one of the jaws whereby the work piece clamped against a face of this jaw can be positioned in an accurate manner in various positions in a plane parallel to the clamping face of the jaw.

Another object is to provide a simple appliance whereby the work piece can be adjusted about an axis disposed within andtransversely of the jaw to which the appliance is applied.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and finally pointed out in the claims.

Y For purposes of illustration I have shown my improvements applied. to a sine vise having a 'i'ixed'jaw. and a rectilinearly movable adjustable jaw, and the device or appliance for controlling the location of the work piece is associated with the fixed jaw. This illustration, however, is only by way of example. A sine vise, such as illustrated, is of a structure such that the bed plate can readily be held in various positions in which its longitudinal axis is tilted relatively to a, horizontal' plane. This enables the work piece to be correspondingly tilted for facilitating operations to be performed thereon, but I have discovered that the adjustability of the work piece should be of greater scope, and that operations upon the workpiece, in the way of cutting,'filing, or the like, are greatly facilitated if there is adjustment of the work piece in a controlled manner in a plane perpendicular to the longitudinal axis of the vise.

In the drawing, the sine vise is shown as having a bed plate 10 having a fixed jaw Ii at one end secured to the upper face of the plate and a rectilinearly movable jaw l2 ,mounted' on the plate to move longitudinally thereof. The'jaw I2 is adjusted by an adjusting device 13, a part ofwhich turns in an upstanding lug M on the bed plate, the adjustment being effected by turning a suitableoperating head. I5. Associated with the bed plate, at the under. part thereof, are fixed rolls lfi and ll which extend transversely ofthe bed plate and enable the same to be readily held in ytilted position when the vise is tilted lengthwise inathe manner above mentioned. that is to say, by moving the longitudinal axis of the vise to a desired angle relatively to a horizontal plane.

It will be seen that the fixedjaw I I, at the right hand extremity of the vise (Figs. 1 and 2), is cut away at I8 to provide a recess in the face of the jaw havinga partly circular innersurface IS. The circle is not complete, for the recess l8 .extends completely to the straight upper surface 20 of the jaw, providing the partly round recess 18 with an open upper end portion 2|. 7

The inner surface IQ of recess I8 is formed on an arc whose center coincides with the center of a longitudinal round bore 22 extending through the jaw H, the right hand end of the bore (Fig. 2) openinginto,recess l8.

Itwill be noted that to the left or forwardly of the jaw H (Fig. 2), adjacent the lower part of the jaw, is located a supporting plate 23 which assists in locating the work piece 24 in the manner hereinafter pointed out. This plate 23 is in the shape of part of a disk, in this particular case being of half-moon formation, and it is 10- catedwith its straight edge 25 uppermost. At the lowerpart, this'plate is received in a socket 26 between the lower part of the jaw II and a shoulder 26 projecting upwardly from the bed plate, the arrangement being such that the lower part of the plate 23 is confined while its upper part projects somewhat into the space 21 provided between what may be termed the front face of the jaw H and the rear face of the jaw 12, whereby the edge portion 25 of plate 23 is adapted to form a bottom support for the work piece 24. At its upper part, the plate 23 is made integral with or secured to a cylindrical shank 28 fitting within the bore 22 and having its forward end flush with the forward face of jaw I I. At its rear end, the shank 28 is provided with a kerf 29 in which is pinned, by a pin.36, the rounded end 3! of a lever 32, This lever isadapted to be adjusted manually from the right hand or rear end of the vise, for the purpose of adjusting the plate 23 about the longitudinal axis of the bore 22 and shank 28 in order that the work piece may be supported at different angles in a plane transverse to the vise.

Fig. 2 shows the vise with a work piece 24 between thejaws, the half-moon plate 23 being shifted to one of its permissible angular locations. It will be observed that, with the parts in the position shown, the adjusting lever 32 is received withinthe recess Hi. In the form Shown, the lever 32 has a small cylindrical handle 33 at the free end substantially in contact with the curved surface l9 of the recess. In this position, the main part of the lever 32 is parallel to the rear face of jaw I I and in contact with that face.

On the handle member 33' is a line 34 adapted to register with a scale 35 applied in a suitable manner to the rear face of the fixed jaw. This scale comprises indicia of various angles, as shown more particularly in Fig. 3, in order that the lever 32, and thereby the plate 23, may be turned to a position in which the work will be held at the desired angle,

It will be evident from Fig. 2 that, when jaw I2 is forced against the work piece, the work piece will hold the plate 23, and its associated

members

28 and 32, in the positions to which they have been adjusted. The

parts

23, 28, and 32 fit in their socketed receiving means in such a manner that there is no play. If it is desired to change the angle of the plate 23, the adjusting means I3 is loosened so as to draw away the jaw I2 from the work piece and the lever 32 can then be turned to bring the plate 23 to the angular position desired.

It is to be noted that the

parts

23, 28, and 32 are readily removable from their socketed receiving means when this is desired. In Fig. 2, the lever 32 is disposed at approximately right angles to its carrying part 28 but it can be swung on its pivot 36 to a position in which it is aligned with part 28, and then, by turning part 23 into an upper position with respect to its turning axis, the

assembly

23, 28, 32 canbe displaced to the left with reference to Fig. 2 in order to remove it from its associated jaw. It will also be understood with what readiness this assembly can be restored to its operatingposition.

In the modification shown in Fig, 5, the shank portion 28 carries a lever 32' having a pointed end 36 which moves-over an angle scale. 31.

Taking the work piece 24 as anexample, it is evident that for cutting, filing, or like operations upon this piece it is of advantage to be able to tilt the vise lengthwise with reference to a horizontal plane, as is done in sine Vises. In the present. case, however, itis possibleto adjust the work piece at compound angles, for it is possible to adjust it in a plane perpendicular to the longitudinal axis of the vise as well as in a vertical plane longitudinal to the vise. This greatly enlarges the scope of the device because it is possible to locate the work piece relatively to any desired planein other words, universally-by proper adjustment of the bed plate relatively to a machine or support and by proper adjustment of the plate 23 relatively to the bed plate. As a result, the machining or other operations upon the work are very much facilitated and it is possible to increase production materially.

In the form of vise shown in Fig. 6, the construction in general is similar to that illustrated in Figs. 1 to 5 inclusive, but the lever 32" has an operating handle 38 flattened off at the outer side, as indicated at 39, and adapted to move within a rectangular recess 40 provided upon the rear face of the vise. In order to locate the work in a very accurate manner, measuring blocks such as indicated at M may be introduced into the recess 40 between the handle 38 and one of the side walls of the recess, as shown.

Fig, 7 shows a vise of the same kind shown in Fig. 6, illustrating the use of a micrometer gauge 42 for measuring the angle of the work. Here the micrometer gauge has a fixed projection 43 abutting one side of the handle 38 whereas the spindle 44 of the gauge abuts at its inner end against a planar surface 45 provided externally on a side wall defining the recess 40.

Another difference between the form of Fig. 7 and that of Figs. 1 to 4 inclusive arises from the fact that in the case of Fig. 7, the shank or plug 28 may be held against turning by clamping means engaging the same at the respective sides. At each side of the plug or shank, a transverse bore is provided in the supporting block, said bore having a screw member 65 operating therein and adapted to be turned from the exterior of the vise. The screw member 65 is adapted to push a, soft metal piece 66 against the side of the block 28 in order to hold it firmly in place.

In Figs. 8, 9, and 10, there is shown a work holder having a base 46 which is a sine base having rolls 4'! and 48 associated with the respective extremities. From the base rises a projection 0r jaw 49 having a horizontal longitudinal bore 50 similar to the bore 22 previously mentioned. In the bore 50 is a work holding and positioning device similar to that previously described, including a plug-like member 5| with a work holding shelf 52 and also including a pivoted operating lever 53-. In this form, however, the work holding shelf 52 is on a semi-circular part 54 that is adapted to be engaged and clamped by a, clamping rod 55 located in alongitudinal bore 56 in the base. The rod 55 is held in position by a screw plug 51 having a polygonal socket 58' (Fig. 9) by which it may be turned from the end of the base.

In this form of the work holder, the work can be clamped on the projecting member 49 in a suitable manner. A number of screw sockets 59 are provided in this member on the inner face thereof at various points above the work holding shelf and, if desired, at points adjacent the respective ends of the shelf. Fig, 9 shows by example the manner of clamping the work piece. Here a work piece 60- is held on the shelf 52, with the shelf in a slightly inclined position, by means of two clamping clips 6| and 62 held in place by

screws

63 and 64 screwedinto two of the screw sockets 59. The work holding shelf is, of course, firmly held in position by the clamping rod 55 engaged therewith, which clamping rod is in turn engaged by the clamping screw 51.

It will be seen from the above that the invention provides a very simple and efiective work holder in which the work can be readily given an accurate compound adjustment. The work piece can be very readily and accurately adjusted in planes that are perpendicular to each other.

Various changes in the organization of parts and details can be made without deparing from the principles of the invention or the scope of the claims.
