l 1 The present invention relates to face plates for vise jaws, and is particularly related to face plates which are removable fromthe associated vise aws.
An object of the present invention is to provide removable face plates for vise jaws which are constructed and arranged to be immovably attached to the related vise jaws so that the work may be securely and fixedly gripped by the face plates.
Another object is to provide face plates of the character described which are constructed to permit refinishing of the active faces thereof so that a smooth surface may always be provided for gripping contact with the work.
Still anotherobject isto provide face plates for vise jaws which are sturdy, and simple in construction, and adapted to mounting upon vise jaws of different configuration without requiring any modification of the vise jaws.
The above, and other objects, features and advantages of the present invention, will be manifest in the following detailed description of a preferred illustrative embodiment, the description being read in connectionwith the accompanying drawing, forming a part hereof and wherein:
Fig. 1 is a perspective view of a face plate embodying the present invention;
Fig. 2 is a rear elevational view of the face plate appearing in Fig. 1;
Fig. 3 is a bottom plan view of the face plate of Figs. 1 and 2;
Fig. 4 is a vertical sectional view taken along the line 4-4 of Fig. 2; and
Fig. 5 is a side elevational view showing two face plates embodying the present invention installed in operative position on a pair of vise aws.
Referring to the drawing in detail, a face plate embodying the present invention is there shown and generally indicated by the reference numeral Ill. The face plate [0 is preferably formed by casting, either in a sand mold or under pressure in a die, and may be made of any suitably soft material of suflicient strength, such as, for example, phosphor-bronze.
The face plate In includes a face member or portion [2 of substantially rectangular configuration having a depth and length sufficient to extend across and cover the gripping face of the vise jaw to which the plate is to be secured. The face portion [2 preferably has a thickness of at least three-sixteenths of an inch so that the gripping or front surface 14 thereof may be repeats 1 Claim. (c1. 81-38) 2 J I edly ground or otherwise refinished to always present a, smooth and unscarred surface for gripping contact with the work, without reducing the thickness of the face portion l2 beyond that point where the latter has sufficient strength to withstand the stresses attending the securing of the face plate to the related vise jaw in accordance with the present invention.
Ears .l6 and 18 extend rearwardly from the opposite ends of the face portion [2 to overlie the opposite ends of the vise jaw when the face portion i2 is abutted against the gripping face of the inafter recited.
A flange 20 extends rearwardly along the top edge of the face portion I2 and is integral, at its opopsite ends, with the ears [6 and H! to further insure against spreading apart of the latter. The unitary construction of the front or face portion t2, the ears [6 and I8 and the flange 20, provides a rigid assembly which permits the use of a relatively soft metal in forming the face plate so that the work gripped thereby will not be indented or otherwise marred.
In attaching the face plate ID to a vise jaw, the face portion 12 is arranged against the gripping face of the jaw, with the ears i6 and I8 overlying the opposite end portions of the jaw and with the flange 20 extending over the top surface of the jaw. In order to hold the face plate II] in the above position, a tapped hole 22 (Fig. 4) is formed through one of the ears, in the illustrated case the ear [6, and threadably receives an Allen screw 24 which may be threaded inwardly to bear against the adjacent side surface of the vise jaw. The vise jaw will then be securely clamped between the inner surface of the ear l8 and the screw 24.
In order to prevent upward swinging of the face plate l0 about an axis corresponding to the screw 24. the hole 22 receiving the latter is disposed substantially below the transverse medial line of the face portion l2 so that any tendency of the face plate to swing in that manner causes the part of the portion 12 above the axis of the screw 24 to bear against the gripping face of the vise jaw for resisting such swinging.
Upward swing of the face plate, which may result from gripping of the work only between the uppermost parts of the faces I4, is further avoided by forming the flange 26 so that it has a thickness of not much more than one-sixteenth 3 of an inch with the top edge of the face l4 being flush with the upper surface of the flange. Thus, even when the work is gripped only between the uppermost parts of the faces M, the reaction to the gripping force will act alone a line that is not much above the top edge of the gripping face of the vise jaw against which the face portion i2 bears, and the moment available for swinging cover the gripping face of an associated vise jaw, ears on the opposite end of said face portion and extending rearwardly therefrom to loosely re-' ceive the sides of the associated vise jaw therebetween, a flange extendingjrearwardly from said face portion flush with the top edge of'the lat xter to rest upon the top of the associated vise the face plate [0 Will be correspondingly small. 1
In Fig. 5, two identical face plates It and Hi are shown mounted upon thejaws 2 6 and 2 8 of a conventional vise 361' It will be noted that the same face plates are adaptedfor'use on either "jaw, said flange being integral at its opposite ends with said ears to resist spreading apart of the latter and having a relatively small thicknessso that thejpa rtof said face portion extendiing above theassociated vise jaw is correspondof the jaws merely by reversing their positions face plate onvise jaws of different sizes'while in each case resisting swinging or other displacement of the face plate relative to the vise jaw.
While I have described and illustrated a pre-.
ferred embodiment of the present inventiomit is to be noted that the latter is not limited to 1 that precise embodiment, and that changes and modifications, obvious to one skilled in the art,
may be madetherein without departing from the scope or spirit of my invention.
What I'claim is:
A faceplate for mounting. on 'a vise jaw com= prising a face portion of substantially rectangular configuration formed to extend across and ingly smallfandian Allen screw threadedly extending throughone of said ears to adjustably bear against the; adjacent side of the associated vise jaw, said screwbeing disposed to rotate about an axis located substantially below the transverse medial line of said face portion to prevent upward. swinging of the latter.
