MAGNETIC VISE JAW Filed May 26, 1950 V A '51 f L5 1.9 f I 18-\ L 4 9 ,19 2o INVENTOR5 PHILIP E. amuse: JOSEPH E. IBRUGGE ksmazqflmnmx9dudawz ATTORNEYS Patented Apr. 27, 1954 UNITED STATES ATENT OFFICE MAGNETIC VISE JAW Philip E. Brugge, Hempstead, and Joseph E. Brugge, Valley Stream, N. Y.

3 Claims. 1

This invention relates to vise jaws or face plates and more particularly to magnetic face plates for either permanent or detachable mounting on the jaws of a vise.

It is among the objects of the invention to prvide a magnetic face plate for a. vise which may be removably attached to a vise having removable face plates or permanently attached to a vise having permanent face plates and which may be of either permanent magnetic or electromagnetic construction, which may include suction. means for holding objects of nonmagnetic material to the face plate, which is strong and durable in construction and will withstand the pressure normally applied to vise jaw face plates, which does not occupy substantially more space than the conventional nonmagnetic face plate, and which is economical to manufacture, and can be easily applied to an existing vise with no material modification of the vise construction.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure 1 is a side elevational view of a fragmentary portion of a vise showing magnetic face plates operatively applied to the vise jaws;

Figure 2 is a cross sectional view on the line 2-2 of Figure 1;

Figure 3 is a top plan view of the vise jaws and magnetic face plates, portions of the face plates being broken away and shown in cross section to better illustrate the construction thereof; and

Figure 4 is a perspective view of an electromagnetic face plate illustrative of the invention.

With continued reference to the drawing the viseillustrated in Figure 1 has a. pair of opposed jaws Ill and I! movable toward and away from each other in the usual manner and provided with key portions l2 and [3 respectively of dovetailed cross sectionalshape for holding face plates on the jaws.

In the arrangement illustrated in Figure 1 a magnetic face plate assembly is mounted on each jaw of the vise, as indicated at It and :5 respectively. The two assemblies are substantially identical in construction so that a description of one only is considered sufficient for the purposes of the present disclosure, the assembly it having been selected for detailed description. It is to be noted that a magnetic face plate may be applied to each jaw of the vise or to only one jaw, as may be desired, in the latter case a nonmagnetic face plate of desired or known construction being applied to the other jaw of the vise.

With particular reference to the assembly 14, this assembly includes a holder [5 having a keyway i l of dovetailed cross sectional shape therein closely receiving the key l2 on the vise jaw so that the holder can be either assembled or disassembled by merely sliding it transversely of the jaw to place the key 52 in the lreyway ll.

In addition to the holder It, the assembly M comprises an elongated, rectangular body It of magnetized material secured on the face of the holder 56 facing the opposite jaw of the vise and disposed opposite the keyway ll. The body I3 may be formed of permanently magnetized material or may be magnetized by a magnetic coil embedded therein.

The body it is provided in its face opposite the holder iii with a recess is which, as illustrated, is of square or rectangular shape and is disposed substantially at the center of the elongated body It. A tapped hole is provided in the body it at the center of the bottom of the recess l9 and a suction cup 20 of resilient material is disposed in the recess E9 and secured to the body i8 by a screw threaded stem 2| which extends from the center of the convex side of the cup 25 and is threaded into the tapped hole in the body It.

The concave side of the suction cup faces in the same direction as the outer face of the body I8 and the rim of the suction cup is disposed slightly beyond the outer face of this body. The amount which the rim of the suction cup projects beyond the outer face of the body !8 can be adjusted by threading the stem 2| into or out of th tapped hole in the body at the bottom of the recess IS. The suction cup 20 is effective to hold a body of nonmagnetic material to the outer face of the body It by suction and the recess It has a sufiicient depth to entirely receive the cup 20 when the opposed face plates of the vise are brought to bear on a body disposed therebetween.

The body 53 is formed of a magnetically permeable material of high structural strength, such as iron or steel and, as stated above, may be either permanently magnetized or magnetized by a magnetic coil embedded therein.

As illustrated in Figure 4, the body l8 corresponding to the body it, is longitudinally divided into three contiguous parts including a lower part 22, an upper part 23, and an intermediate part 2%. Both upper and lower faces of the intermediate part it are longitudinally grooved to provide rectangular grooves extending slightly less than the length of this part and at the ends of these grooves the part is apertured to connect the two grooves at both ends thereof. The

lower part 22 is grooved in its upper face to provide a recess registering with the groove in the lower face of the intermediate part 24 and the upper part 23 is grooved in its lower face to provide a recess registering with the groove in the upper face of the intermediate part. The registering grooves in the intermediate and the lower and upper parts provide recesses of rectangular cross sectional shape extending longitudinally of the body and connected at their opposite ends. A magnetic coil 25 is mounted in this continuous recess in the hollow body I8 and lead wires 26 extend from this coil out of the body at one end of the latter for supplying electrical energy to the coil to magnetize the body. The three parts or bars 22, 23 and 24 are provided at their opposite ends with registerin apertures, and fasteners, such as the screws or bolts 27 extend through these apertures and secure the three parts together in superimposed relationship. Apertures 28 extend transversely through the lower and upper parts for the reception of pins or screws for attaching the body 18 to a vise jaw or a holder, such as the holder 16.

In using the device, work pieces such as the small pieces 39 and 31 may be placed against the magnetic face plate and will be held against this face plate while being positioned relative to each other in a predetermined relationship. After the parts have been properly positioned they will be held against the magnetic face plate of the vise while the opposed face plate is being closed on the work, thus greatly facilitating the positioning of work pieces in a vise. operations two operators are required to position work pieces in a vise and close the vise on the work pieces with the Work pieces held in proper position relative to each other. With the magnetic face plate of the present invention, this can be accomplished by one operator with a material saving of time over the results obtained by two operators with nonmagnetic face plates.

The invention may be embodied in other specific forms without departin from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the

In many 4 scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:

1. A vise face plate comprising an elongated body of magnetized material having a recess in one face thereof, and a suction cup of resilient material mounted in said recess.

2. A vise face plate comprising an elongated body of magnetized material having a recess in one face thereof, and a suction cup of resilient material mounted in said recess, said recess being disposed substantially at the center of said body and having a depth sufiicient to receive said suction cup entirely therein.

3. A vise jaw face plate assembly comprising a holder havin a keyway therein for receiving a key on a vise jaw, an elongated body of magnetized material secured on the face of said holder opposite said keyway and havin a recess in the face thereof opposite said holder, and a suction cup of resilient material adjustably mounted in said recess.
