shire, Clerk, do hereby declare the nature of our invention for IMPROVEMENTS IN
VICES, to be as follows:-
"
We apply a
Washer" on the Vicebox and one under the collar of Vice Screw,
with two semicircular lugs on each Washer, which fit into corresponding recesses,
outside of the eyes of the Vice, in order to keep a level bearing of the collar of
Vice Screw on the washer when the Jaws of the Vice are open and to relieve the
Vice Screw from any uneven strain.

page_text: We THOMAS HUNT of Attleborough, Warwickshire, Engineer and CHARLES PEGG
of Chilvers Coton, Warwickshire Engineer and FREDERIC TURLAND of Chilvers
Coton, Warwickshire, Clerk do hereby declare the nature of our said Invention for
." IMPROVEMENTS IN VICES" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :—
Our invention consists of the improvements hereinafter described and illustrated
in the accompanying Drawings in vices.
In vices as ordinarily constructed the collar of the vice screw, bears directly
against the moveable or front jaw of the vice and the collar on the vice screw
consequently does not take a level or continuous bearing on the said jaw. The
fixed or back jaw also takes a direct bearing against the face of the vice box.
The object of our invention is to relieve the vice screw and vice box of undue
strain which we effect by applying a washer to the vice box and another under the
collar of the vice screw. Each washer is furnished with two semi circular lugs
which fit into corresponding recesses in the front and back jaws of the vice and
prevent the rotation of the said washers. By means of the said washers a level or
continuous bearing for the collars of the vice screw and vice box is provided and
the said vice screw is thereby relieved from uneven strain.
Figure 1 represents in side elevation and Figure 2 in plan a vice containing our
improvements; Figure 3 represents a plan of the same without the jaws of the
vice; Figures 4 and 5 represent side elevations taken at right angles to one another
of the lugged washer situated at the vice screw and Figure 6 is a front elevation of
the same; Figures 7 and represent side elevations taken at right angles to one
another of the lugged washer used at the vice box; Figure 9 is a section and
Figure 10 a front elevation of the same. The same letters of reference indicate the
same parts in the several Figures of the Drawings.
a is the moveable or front jaw or leg and 6 the fixed or back jaw or leg of the
vice; c is the vice screw working in the vice box, d carried by the fixed jaw b;
e is the collar of the vice screw; f is the lugged washer for the said collar e of the
vice screw to take a bearing against; g, y are the semi circular lugs on the inner
face of the said washer f, curved notches or depressions at h (sce Figure 1) being
made near the eye of the moveable jaw a for the lugs g, g to engage with, the said
lugs being maintained in gear with the jaw a by the spring i pressing the said jaw
open. The hole g³ in the washer f is circular and takes upon the plain end of the
Screw C. The face of the washer against which the collare of the vice screw
bears is flat. As the vice screw c is turned in the direction proper for the closing
of the vice, the collar e of the said screw bears against and advances the washer f
and the snugs g, g of the washer bearing against the moveable jaw a advances it
towards the fixed jaw b. As the screw c is turned in the opposite direction for
opening the vice, the lugged washer f. g retires with the flange or collar e of the
screw, the moveable jaw being pressed back against the lugged washer by the
spring i.
It will thus be understood that the bearing of the collar of the vice screw upon
the lugged washer is continuous that is the pressure is equal on both sides of the

page_text: axis of the screw whatever positions the moveable jaws occupy and hence the vice
screw is relieved from uneven strain.
The lugged washer at the screw box d is marked k and its lugs l, l. The said
lugged washer I, l has a hole in it of a size sufficiently large to take upon the
barrel of the vice box d the said barrel being prevented from rotating on the
said washer by a key or feather m taking into a slot or key way in the said
barrel. The lugs 1, of the washer k engage with the depression in the fixed
jaw b and the flat face of the said washer / bears against the collar d³ of the vice
box d.
By means of the lugs l, and depression n the screw and screw box of the vice
are capable of making an angular motion upon the fixed jaw b and the strain put
upon the screw and screw box is always maintained in the line of the axis of the
screw in whatever position the moveable jaw may be.
We do not limit ourselves to the configuration represented of those faces of the
lugged washers which take into or engage with the jaws or legs of the vice as such
other forms may be given to the said faces as will permit of their taking a firm
bearing against the jaws or legs of the vice. For example, the faces of the
washers f, may have the convex curved figure represented in Figure 11 of the
Drawings, the outer faces of the jaws or legs a, b having correspondingly shaped
depressions for the convex faces of the washers to bear against as represented.
Or the bearing faces of the jaws or legs and washers may be reversed as
represented in Figure 12, that is, convex lugs or projections are made on the outer
faces of the jaws or legs a, b and the washers f, k are provided with depressions for
taking upon the said lugs or projections.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention of "Improvements in vices"
Interposing between the collar of the vice screw and the moveable jaw or leg,
a lugged semi circular or curved washer for the purpose, of. relieving the said screw
from uneven strain and interposing between the collar of the vice box and the
fixed jaw or leg, a nearly similar lugged semi-circular or curved washer for the
same purpose; or making the jaws or legs with lugs or curved projections and
the interposed washers with depressions for receiving the said lugs or projections,
the said washers being constructed and combined with the other parts of the
vice and acting substantially as herein before described and illustrated in the
accompanying Drawings.
