4 Claims. 1

This invention relates to improvements in vises.

The invention relates particularly to vises for use in the fabrication of metal tubing whereby the tubing may be sawed while supported in the vise and also whereby the sawed off end may be faced while supported in the same vise so that the faced end is smooth, flat, and square with the axis of the tube, with no objectionable burrs left from the sawing operation. Heretofore, after sawing off a section of tubing, the burrs have been removed by means of a file or scraper, and this frequently results in a beveled edge and in an irregular face.

A more specific object of the invention is to provide a vise having means for removably clamping a tube in position, the vise having a sawing slot, and the vise also having an end extension provided with an annular shoulder which is parallel to said sawing slot. Thus, after the sawing operation, the clamping pressure in the vise may be temporarily released and the sawed end of the tube pushed forwardly to project slightly beyond the annular shoulder. The shoulder is constructed for cooperation with the jaws of a standard hand facing tool to support the tool so that its cutter will operate on the projecting tube end to perform a smooth, fiat facing operation which is absolutely square with the axis of the tube.

A further, more specific object of the invention is to provide a device as above described wherein the vise comprises two hinged-together half sections which are adapted to clampingly engage the tube, each half being provided with a semi-cylindrical extension, and each of said extensions being provided with a semi-circular annular flange for cooperation with the jaws of a standard facing tool.

With the above and other objects in View, the invention consists of the improved vise, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying drawing, illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals designate the same parts in all of the views:

Fig. 1 is a perspective view of the improved vise showing it mounted on a fragment of a work bench and showing a sawing operation being performed;

Fig. 2 is an edge view of the vise, after the sawing operation has been performed, illustrating a seating and facing tool cooperating with the vise 2 to perform a facing operation on the sawed end of the metal tubing; and,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2.

Referring more particularly to the drawing, the numeral 5 designates a base for the vise which is adapted to be secured by bolts 6, or other suitable means to a work bench I. The upper surface of the base is formed with a transverse fixed clamping projection 8 having a V- shaped, horizontally extending ridge on one face thereof.

The vise proper includes complementary half sections iii and II which are hinged together on pins l2. The half section It has a depending leg l3 which is formed with a V-shaped recess M for engagement with the rib 9 in the base projection 8 in the manner shown in Fig. 3. The other half section II is formed with a depending leg l5 of substantially the same length as the leg I3. A saw guiding slot it extends downwardly into both of the sections [0 and H, transversely of the aXis thereof, and terminates at ll near the upper portions of the legs l 4 and i5. The saw guiding slot extends through the hinged portion and therefore the hinge pin I2 is formed in two aligned sections, one on each side of the slot [6.

The half sections 10 and II are formed with complementary half bores IS and 2:3 which extend entirely through the vise and which are adapted to clampingly receive a length of metal tubing 2| in the manner shown in the drawing.

Any suitable means may be employed for forcing the'legs l3 and I5 together to clamp the tube within the vise. It is preferred to utilize a cam 22, mounted on the base 5, the cam having a handle 23 and being rotatable on an eccentric pin 24 to releasably clamp the device around the tube in the manner shown in Fig. 3.

Projecting from one face of the section In is a semi-cylindrical extension 24% having a semi-circular annular shoulder 25 at its end. Projecting from the corresponding face of the section II is a semi-cylindrical extension 26 having at its end a semi-circular annular shoulder 21. When the vise is in use, the semi-circular extensions cooperate to engage and fit a portion of the tubing extending therethrough. The inner face 28 of the shoulders 25 and 2'! is parallel to the saw guiding slot 16.

In use of the improved vise, a section of tubing to be operated upon is positioned as shown in Fig. 1, with the device locked in clamping posi tion. By inserting a hack saw 29 or other suitapproximately able tool in the slot [6 the tube 2| may be severed along a line at right angles to the axis of the tool. After the sawing is completed the handle 23 of the clamping cam is swung from the full line position of Fig. 3 to the dot-and-dash line position to release the clamping action on the legs I3 and [5. The sawed off end 30 of the metal tube 2! may then be pushed forwardly to pro ject a slight distance beyond the annular shoulder 25, as illustrated in Fig. 2. The handle 23 controlling the clamping cam is then moved back to the full line clamping position of Fig. 3. The tube-end is now ready for a facing operation.

In Fig. 2 is illustrated a hand seating and facing tool 3|. This type of tool is well known and is available on the market. One of such tools is sold as a Jiffy Seater. It includes three pivoted hook-like holding jaws 32 which are equally spaced; a rotatable spindle 33 for receiving and operating a facing tool 36; an adjustment screw 35, operable to bring the tool into engagement with the work; and a manually operable handle 36 fo rotating the tool to perform the facing operation.

By providing the extensions 24 and 26, with the complementary shoulders 25 and 21, on the vise used for the sawing operation, and by having the inner face 28 of the shoulders parallel to the saw guiding slot It, means is provided whereby the facing tool 3! may be quickly connected to and supported on the same vise used for sawing to perform an accurate facing peration on the tube-end 30. The jaws of the facing tool 32 may be easily engaged with the shoulder portions 25 and 2'! in the manner shown in Fig. 2, and manual rotation of the handle 33 will rotate the cutter Eli and cause all objectionable burrs from the sawing operation to be removed from the tube-end 30. The cutting tool will also perform a facing operation which is smooth, fiat and square with the axis of the tube.

Various changes and modifications may be made without departing from the spirit of the invention, and all of such changes are contemplated as may come within the scope of the claims.

What I claim is:

1. A vise comprising means for releasably holding a section of tubing, said holding means having an end face; means forming a cylindrical extension projecting beyond said end face of said first means and positioned so that tubing supported in said first means may project through said cylindrical extension; and annular shoulder forming means on said cylindrical extension projecting beyond said end face of said holding means and having a face extending at right angles to the axis of said cylindrical extension positioned for engagement by a facing tool to position the latter for operation on a tube end projecting from said extension means.

2. In a vise having a pair of complementary sections each formed with a semicylindrical bore for clamping a section of tubing therebetween: a semicylindrical extension projecting from an end of each section; and a semiannular flange adjacent the end of each extension and spaced beyond the end of said sections, said flanges having tool positioning faces which extend'at right angles to the axis of tubing supported in the vise and extensions.

3. A vise comprising means for releasably holding a section of tubing, said holding means having an end face, means forming an extension projecting beyond said end face of said first means and positioned so that tubing supported in said first means may project through said extension means, and annular shoulder forming means on said extension means spaced beyond said end face of said holding means and having a face extending at right angles to the axis of said tube holding means positioned for engagement by a facing tool to position the latter for operation on a tube end projecting from said extension means.

4. In a vise having a pair of complementary sections each formed with a semicylindrical bore for clamping a section of tubing therebetween: an extension projecting from an end of each of said vise sections; and a semiannular flange carried by each of said extensions and spaced beyond the ends of said vise sections, said flanges having tool positioning faces which extend at right angles to the axis of tubing supported in the vise and extensions.
