11 Claims.

This invention relates generally to a combined angle plate and clamping device and more particularly to a combined angle plate and clamping device which has novel means for quickly attaching and detaching a movable jaw.

Base plates and angle plates now on the market are quite expensive inasmuch as T-slots are formed crosswise of the plates which require much time and expense in milling operations. Vises now have a movable jaw with a screw and nut for moving same requiring considerable time to move a jaw to a given position. The capacity of these Vises is limited because of the limitation of the opening thereof. It is diicult to square up a workpiece in present vises.

It is, accordingly, an ob;l ect of my invention to rovide a combined angle plate and clamping device for toolroom use which is simple in construction, economical in cost, economical in manufacture, and simple in operation.

Another object of my invention is to provide a combined angle plate and clamping device wherein the slots in the angle plate comprise spaced cross slotted cylindrical apertures in which a depending angle member of a movable jaw slides for fastening same to said angle plate at predetermined distances from the vertical plate thereof.

Another object of my invention is to provide in a clamping device a movable jaw for disposal .xy

in a minimum of time at different xed distances from a fixed jaw.

Another object of my invention is to provide a movable jaw on a combined angle plate and clamping device, the movable jaw being movable longitudinally and vertically.

Another object of my invention is to provide a combined angle plate and clamping device in which two jaws may be utilized.

Another object of my invention is to provide a combined angle plate and clamping device wherein rectangular and round workpieces may be accommodated. f

Another object of my invention. is to provide a combined angle plate and clamping device which has provisions for attaching a clamp thereto for securing a round workpiece or a comparatively large workpiece externally thereof.

Another object of my invention is to provide a combined angle plate and clamping device so constructed that it may be manufactured in a minimum of time.

Other objects of my invention will become evident from the following detailed description,

taken in conjunction with the accompanying drawings, in which Fig. 1 is a perspective view of my novel combined angle plate and clamping device;

Fig. 2 is a perspective view of my novel angle plate with a round piece clamped thereon;

Fig. 3 is an enlarged fragmentary side elevational view of the fastening means for support for my novel movable jaw;

Fig. 4 is a fragmentary sectional view of the clamping jaw and the lead screw and shaft connected thereto;

Fig. 5 is a side elevational View of my novel angle plate with a flat piece in position to be clamped to the outer side thereof; and

Fig. 6 is a side elevational view of my novel angle plate with a round piece clamped therein.

Referring now to the drawings, I show in Figs. l to 6 inclusive an angle plate I having a Vertical face 2 and a horizontal face 3 at right angles to each other. The vertical face 2 forms the xed jaw of a clamping device as Will be hereinafter described. The horizontal face 3 has transverse slots 4 spaced from each other and from the face 2 of the angle plate I, the slots 4 terminating in cylindrical, transversely extending apertures 5. The slots 4 are cut tangent to the side of the apertures 5 adjacent the vertical face 2. It will be seen that it is a simple machining operation to drill the apertures 5 and then cut a slot 4 from the top face 3. The cost of this operation is many times cheaper than forming a T-slot. The angle plate I has a corner thereof cut away at forty-five degrees to form a beveled surface 6 to accommodate a jaw of a parallel jaw clamp 'I to secure a round piece 9 on the angle plate I as shown in Fig. 2.

A U-shaped member I0 has an L-shaped depending portion I2 so that it may be secured to the angle plate I by merely sliding the depending portion I2 into any of the slots el as shown in Figs. 1 and 3 to dispose it in any desired position spaced from the face 2 of the angle plate I. A vertically slidable H-shaped block I3 has grooves I4 formed on opposite sides thereof so that it slides vertically between opposed legs I5 of the U-shaped member I 0. The block I3 has a longitudinally extending, threaded aperture I5 for threadably receiving a lead screw Il having a jaw I8 mounted on the end thereof adjacent the face 2 of the angle plate I. A knurled handle I9 is formed on the end of 'the screw I'I opposite to the jaw I8. The handle I9 has radially extending apertures'ISa therein for the insertion of a small bar to rotate the 'screw Il. The

block I3 also has a longitudinally extending aperture 2U disposed below the threaded aperture I6 and parallel therewith, the aperture 2li slidably guiding a rod 2I. A plate 22 is secured to the end of the rod 2I by a screw 23 and it has a bifurcated end 22a nested in a peripheral groove (not shown) on the lead screw I1. The rod 2I and the lead screw I1 have reduced end portions 24 and 24a which extend into

parallel recesses

25 and 25a in the jaw I8 whereby the jaw I8 is held in a vertical position. The jaw I8 has a projecting portion 26 on one end thereof to engage a workpiece as shown in Fig. 1. The block I3 may be reversed so that the projecting portion 26 may be on the lower portion of the jaw I8. various positions.

In the operation of my novel device as an angle plate, the movable jaw supporting member I is removed from the angle plate I. When it is desired to use my novel device as a clamping device to hold a workpiece against the face 2 of the angle plate I as in Fig. l, the depending portion I2 of the member I0 is inserted into the desired slot II in accordance with the thickness of the workpiece to be disposed against the face 2 of the angle plate I. The vertically slidable block I3 is then disposed between the legs of the U- shaped member I0 in the desired vertical position, as shown in Fig. l, and the handle I9 on the lead screw I1 is rotated until the projecting portion 26 of the jaw I8 engages a workpiece disposed against the face 2 of the angle plate I. The slidable block I3 may be disposed in any vertical position in the U-shaped member Ill and the U-shaped member I0 may be moved laterally to any desired position before the projecting portion 26 of the jaw I8 enga-ges the workpiece. This is determined in accordance with the shape and height of the workpiece. When the vertical height of the workpiece is relatively small, the slidable block I3 is reversed so that the projecting portion 26 of the jaw I8 is on the lower side thereof. It will be evident that my novel combined angle plate and clamping device may n.

be set up quickly and it will hold a workpiece of maximum size as compared with present vises now on the market. In present conventional vise jaws, there must necessarily be play in the movable jaw which results in the engagement of a workpiece by one side of the movable jaw in many instances, thereby causing uneven clamping. My device always produces square even clamping.

A comparatively large workpiece 3l may be attached to the outer or back face 30 of the angle plate I in the position shown in Fig. 5 by the parallel jaw cla-mp 'I shown inFigs. 2 and 6. The round workpiece 9 may be secured on the angle plate I by the parallel jaw clamp 1 as shown in Figs. 2 and 6 with the one jaw of the clamp 1 engaging the round workpiece 9 and the other jaw of the clamp 'I engaging the cut awa-y portion Bon the lower corner of the angle plate I. My'angle plate is :particularly suitable for securing a round workpiece with a clamp 1 so that the end of the round workpiece 9 may be worked upon with Vthe angle plate I sitting on its side.

My novel angle plate I may accommodate two or more U-shaped members I'ac'cording to the width of the face 3 .-thereofso that two or more clamping jaws I8 may be provided to hold a workpiece squarely against the vertical face 2 of the angle plate I.

The block I3 is also movable vertically to It will be evident from the foregoing description that I have provided a novel combined angle plate and clamping device particularly useful for close tolerance work, such as for use in a toolshop, whereby it may be used as an angle plate or as a clamping device which may be set up in a minimum of time, which has novel attaching means for a movable jaw of a clamping device, and a combined angle plate and clamping device which is extremely simple in manufacture and economical in cost.

Various changes may be made in the specific embodiment of my invention without departing from the spirit thereof or from the scope of the appended claims.
