IMPROVEMENTS IN VICES
Year: 1885

page_text: I, PETER MINEA, of 65 Concord Street, St Paul, in the County of Ramsey, and
State of Minnesota, United States of America, Wagon Maker, do hereby declare
the nature of my 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 :-
Fig. 1 is a perspective view of the vice complete.
Fig. 2 is a perspective front view, and
Fig. 3 is a perspective rear view of one of the removable jaws detached.
Fig. 4 is a perspective front view, and
Figs. 5 and 6 are perspective rear views of one of the "cheek plates," Fig. 4
showing the construction of the face of the plate, Fig. 5, showing the construction
of the rear of the plate viewed from above, and Fig. 6 showing the construction of
the plate viewed from below at the rear.
Figs. 7, 8 and 9 are detached perspective views of the removable jaws showing
the various forms in which they will be constructed.
Fig. 10 is a sectional side view of the upper parts of the vice without the
removable jaws.
A¹ A are the two main jaws of the vice, having the usual screw, B', hand.
lever, B, and parallel cross bars C¹ C', in the ordinary manner.
Attached to the inner face of the upper part of each of the jaws A¹ A³, are metal
cheek plates D, with their upper parts projecting over their lower parts, as shown,
leaving recesses or depressions a, in each. A slot b, is formed through each cheek
plate, as shown in Figs. 4, 5, and 6, and the faces of the slot within the depressed
parts a, are covered with curved hoods d, the slots and hoods thus forming sockets
adapted to receive the tapering points e¹, of the legs e³, of auxilliary jaws or cheek
plates E..
By this means the auxilliary jaws may be inserted or removed at pleasure by
merely lifting them upward.
The legs e, are shown with offsets so that the points e¹ may be inserted into the
sockets at the backs of the depressions a, and with the rears of the jaws E resting
against the face of the cheek plate D, so that when the vice is in use the pressure
will be borne by the bodies of the auxilliary jaws resting against the faces of the
cheeks D, which in turn rest against the main jaws of the vice, so that the pressure
will in no case be borne by the legs e² or points e¹.

page_text: The depressions a, in the cheek plates D are a very important feature of my
invention, as they enable me to. support the auxilliary jaws with the hoods d, in
line back of the upper parts of the faces of the cheeks D, so that when the
auxilliary jaws are removed no part of the cheek plates projects beyond their
upper parts, to enable the vice to be used as an ordinary vice when the auxilliary
jaws are removed. This will be more clearly understood by reference to Fig. 10
which shows the vice with the auxilliary jaws removed.
Each of the jaws A' A' will be provided with one of the cheek plates D, so that
the auxilliary jaws, may be attached to either cheek; or, if required, two of the
auxilliary jaws may be used, as shown in Figs. 7 and 8, which represent a concave
jaw and a convex jaw adapted to hold curved pieces between them.
It is evident that any desired form of jaw may be used, and in practice I intend
to furnish with each set of cheek plates D, a series of auxilliary jaws adapted to the
varied forms of the work to be held.
In Figs. 1, 2, and 3, the auxilliary jaw E is formed with an angular back, and
adapted to turn upon the legs e, so that the face of the jaw will adapt itself to the
form of the work being held in the vice. This form of jaw will hold with an
equal pressure all angles within the radius of its movements.
In Fig. 9 an auxilliary jaw is shown, with the inclination at right angles to the
inclination of the jaw shown in Figs. 1, 2, and 3.
This invention may be attached to nearly every form of vice; but it will
generally be used on the wooden vices used by carpenters, wagon makers, pattern
makers, &c.
The invention may be applied to old vices, or attached to and sold with new
vices, as preferred.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st As a new article of manufacture, a vice cheek plate D, having a depressed
portion a, slot b, and socket d, and adapted to support an auxilliary jaw E,
substantially as set forth.
2nd In a vice, cheek plate or plates D having depressed portions a, slot b, and
Bockets d, and adapted to be attached to the jaw or jaws of a vice, in combination
with auxilliary jaw or jaws E having legs e, and pivotal points e¹, substantially as
set forth.
