COMPLETE SPECIFICATION.
Improvements in Auxiliary Cheeks and Jaws for Vices.
I, OTTO PETERMANN, of 296, Bahnhofstrasse, Müllheim, Switzerland, Manu-
facturer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to auxiliary cheeks and jaws for parallel or ordinary vices
which is free from the disadvantages of similar known devices, such as the space
occupied by the devices interfering with the clamping of the articles in the vice,
and the adherence of the auxiliary cheek to the article; further auxiliary cheeks
bent from sheet metal, have never a sharp upper edge and the repitition of
bending the edges makes them quickly used up, and thus wastes material and
time.
In order that this invention may be the better understood, I now proceed to
describe the same, reference being had to the accompanying drawings and to the
letters and figures marked thereon.
Figure 1 is a front view of an auxiliary cheek attached to a vice.
Figure 1 is a plan thereof.
Figure 1b is a side view thereof.
Figures 2, 2 and 2b are front view, plan and side view, respectively, of such a
cheek with a facing of wood or other material.
Figure 3 is a side view of a cheek with facing having oblique faces.
Figures 4, 4 and 4b are front view, plan and side view, respectively, of a cheek,
elongated beyond the side of the vice and adapted to receive a lining or facing.
Figures 5, 5 and 5b, are front view, plan and side view respectively of a
modified elongated cheek.
Figure 6 is a side view of a cheek adapted to render ordinary vices parallel
vices.
Figure 6 shows a horizontal section therethrough.
A strip of sheet metal a, Figures 1, 1, 1b, is bent twice at each end to form

is to be used, it need only be pushed over the cheek or jaw of the vice, the sides b
of the auxiliary cheek fit against the side of the permanent cheek or jaw, the
ends c slide in the grooves e to prevent the auxiliary cheek falling off towards the
front and the upper piece d fits as beforesaid over the edge of the permanent cheek

cheek is thus securely attached to the permanent cheek.
This main form of auxiliary cheek may be modified in various ways to render it
more useful for various purposes.
As shown in Figures 2, 24 and 2b the auxiliary cheek is adapted to be lined
with blocks h of wood or other material. For this purpose oblique bars or
projections f Figure 2", are provided over which fits the lining block h, which has
grooves i corresponding to the bars or projections f. To prevent the block h

page_text: sliding off downwards the lower edge of the front a of the auxiliary cheek has a
piece g.bent outwards on which the block h rests.
Figure 3 shows a combination of such lined auxiliary cheeks, the blocks of
which are cut oblique to serve as parallel vice clamps. For this purpose one
cheek, 7, is attached to the vice reversed so that the pressure acting on its oblique
face cannot dislodge it by reason of the projection d. This form is of great value
for its purpose, and obviates the annoyance caused by the hinged part of the usual
vice clamp.
Another modification is shown in Figures 4, 4" and 4b. The form is similar
to the main form, Figures 1, 1" and 1b, but the cheek a is elongated sideways to
extend beyond the side of the check or jaw of the vice, in order to allow of long
pieces being clamped vertically in the vice. Of course this modification may be
made with or without projecting bars f to fix lining blocks.
Figures 5, 5, 5 show an elongated cheek, adapted to be attached to a cheek
of the main form, Figures 1, 1, 1, with oblique projections as shown in
Figures 2, 2, 2b.
The front piece has grooves i which are adapted to fit over the oblique
projections of a cheek a, as shown in Figure 2. On the front of the piece p
is a piece having oblique projections f to receive a lining piece as before
described. In order to strengthen the elongated part n, Figures 4, 5, &c. as much
as possible, a horizontal ribo is provided and the piece d which fits over the
edge of the vice is made wider.
Figures 6 and 6 show a modification by which ordinary vices, which clamp
a piece obliquely, are transformed into parallel vices. For this purpose the
cheeka is provided with a dovetailed lining or armature r, in which a solid semi-
cylindrical piece s is adapted to turn. This semi-cylindrical pieces carries on
its front the plate or armature q with the projections f for a linifig block. It is
obvious that the armaturer may be made separately and provided with grooves i
to attach it detachably to the bars f of the main form of cheek a.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is―
1st. An auxiliary cheek for vices, consisting of a metal strip a, each end of
which is bent twice at right angles, to form sides b to fit the sides of the jaw of
the vices, and short ends c to fit into grooves e of the jaw of the vice, a pieces d
bent over at the top, resting on the top of the jaw of the vice to prevent the
sliding down of the cheek a, substantially as described.
2nd. A form of construction of the cheek . as claimed in Claim 1, in which are
provided two oblique guiding bars or projections f over which is pushed a
lining piece h having grooves i, and a piece g bent out at the lower edge so as
to prevent the sliding down of the lining piece h, substantially as described.
3rd. A form of construction of the cheek as claimed in Claims 1 and 2,
having an elongation » sideways of the vice, stiffening ribs o, and an overlapping
stiffening piece d to permit the clamping of long pieces vertically, substantially
as described.
4th. A form of construction of the cheek claimed in Claim 1 consisting of the
cheek and an armaturer fixed or detachably attached thereto having a segmental
recess in which is adapted to turn a semi-cylindrical pieces having a front
plate or armature g adapted to receive a lining piece or face, in order to effect the
parallel clamping of the work, substantially as described.
