Application February 3, 1947, Serial No. 725,987
This invention relates to a vise jaw attachment and more particularly to an attachment for securely fixing a plurality of rods or tubes in one vise.
It is often required or desired in working metal to clamp at least a pair of tubes or rods parallel to each other in a vise for performing certain milling or other machine work on both rods at the same time. While the diameters of similar rods are designed and intended to be identical, it is known in practice that the very small variation in the diameters of such rods frequently precludes the possibility of clamping two rods parallel in a vise, as the smaller will be loose between the vise jaws. Therefore, when the same work is to be performed on two or more rods, it is necessary to mill or otherwise machine each rod separately. This separate working on each rod requires the operator to re-set and readjust the clamp or jigs for each rod as it is machined, thus requiring a great amount of labor, time and expense.
It is an object of this invention to overcome the above named labor and provide a resilient member for use with a recessed vise jaw as an attachment of the kind to be more specifically described hereinafter, which will secure two or more rods in one vise whereby a machine operation may be performed on the rod simultaneously.
Another object of this invention is to provide an attachment of this kind which may be readily manufactured and assembled at a low cost whereby it may be sold at an economical price.
Still another object of this invention is to provide an attachment of this kind which may be used on a vis'e jaw having a upwardly opening grooved face whereby the attachment may be readily installed in or removed from the vise.
With the above and other objects in view, my invention consists in the arrangement, combination and detaiIs of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.
In the drawing,
Figure 1 is a top plan view of a vise jaw and a vise jaw attachment constructed according to an embodiment of this invention,
Figure 2 is a plan view of the attachment removed from the vise, V
Figure 3 is a fragmentary longitudinal section taken on the line 3-3 of Figure 2,
Figure 4 is a transverse section, partly broken away, taken on the line 4-4 of Figure 2.
Referring to the drawing, the numeral l designates generally a vise jaw having a vertical grooved face II for use primarily in supporting cylindrical rods or tubes as l2, of substantially the same diameter while the tubes are being worked on by a milling machine or other similar machine cutting tool.
While the rods 12 are identified as being of the same diameter, it is customary and usually found that variations of a few thousandths of an inch will be experienced and found in the same shipment of tools. When it is desired to work on these rods or tubes [2 and the same machine operation is to be applied to more than one rod, it is desirable that the rods should be clamped together in the same vise so that they may be machined in the same operation and have the same work done upon them. In ordinary or conventional types of vises having a flat face, two or more such rods cannot be supported therein because the larger of the rods will engage the opposed faces of the vise and the smaller rod will not be clamped securely therein. It is an object then of this invention to provide an attachment for a vise jaw which may be suitably resilient to yield for gripping the larger of the rods I2, and yet will be substantially rigid for securely clamping the smaller rod.
The vise jaw attachment I4 is formed of a plurality of longitudinally extending parallel metal strips l5 and a plurality of transversely extending metal strips [6 parallel to each other and at right angles to the longitudinally extending strips IS. The longitudinal strips [5 are woven with or engaged with adjacent and overlapping transverse strips 16 by alternately engaging over and under the adjacent transverse strips. Such engagement forms a, substantial woven metal mat which is suitably resilient for yielding under pressure and will be still sufficiently rigid for clamping the smaller adjacent rods as described above.
For attaching the mat M to the vise jaw ID, the recessed or notched face H is provided along opposite edges thereof with inwardly extending grooves H which extend along the length or depth of the face and the mat I4 is adapted to slidingly engage between the opposed grooves l I. For securely binding the edges of the attachment I4 in the groove I1, the opposite ends of the mat l4 may be folded as at it, to provide a double thickness for frictionally engaging in the grooves.
In the use of this mat, it is intended that the attachment [4 should be substantially bowed as at 19 relative to the fiat face I! so that the resiliency of the mat will become effective on the work [2 prior to the initial clamping force being applied thereto. While the intersection of the inter-engaged strips l5, [8 provide a plurality of corners and edges for frictionally supporting the work I2 against sliding movement, it is desired that the strips should be formed with notches or grooves 20 on the forward side thereof for increasing the frictional resistance between the mat l4 and the work. The grooves 29 are formed diagonally of the strips l5, l8 and intersect crossing strips at right angles thereto.
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
What I claim is:
1. A vise comprising a jaw member formed with a recessed wall, said jaw member having flanges spaced from said recessed wall and overlying opposite ends of said recessed wall to form confronting channels, and a resilient work engaging member having a linear surface distance between an opposite pair of sides that is slightly greater than the distance between said confront ing channels, said resilient work-engaging meme her having said opposite sides positioned in said confronting channels, and said work-engaging member being normally bowed outwardly from said recessed wall, whereby said work-engaging member can yieldably conform to the shape of work-pieces clamped in said vise.
2. A vise comprising a jaw member formed with a recessed wall, Said jaw member having flanges spaced from said recessed wall and overlying opposite ends of said recessed wall to form confronting channels, and a resilient work engaging member including interwoven flat strips, said member having a linear surface distance between an opposite pair of sides that is greater than the distance between said confronting channels, said resilient work-engaging member having said opposite sides positioned in said confronting channels, and said work-engaging member being normally bowed outwardly from said recessed wall, whereby said work-engaging member can yieldably conform to the shape of workpieces.
