U-FICTION COlar late lor vices.
I, CARL WISSENBACH, of 5, Schillerstrasse, Frankfurt-on-the-Main, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:
This invention for an improved anti-friction collar plate for vices has for its
object to provide a collar plate adapted to be interposed between the head of the
screw and the movable jaw of the vice to reduce the friction between the parts,
and consists of a collar plate formed on one side with nose pieces for bearing
against the jaw of the vice, and at the other side with a ball bearing against
which the head of the screw works.
In carrying out this invention a collar or ring adapted to be mounted on the
vice screw between the head of the screw and the movable jaw of the vice, is
formed on its back face with nose pieces for bearing against the movable jaw,
and on its front face with a ball race in which bearing balls are placed, the race
being closed by a steel bearing ring that enters a recess in the face of the collar.
The head of the vice screw bears against the bearing ring and rotates it on the
balls when transmitting the pressure to the movable jaw of the vice. A pin on
the movable jaw engages between horns on the collar plate and prevents it from
turning with the screw.

An Improved Anti-friction Collar Plate for Vices.
I, CARL WISSENBACH, of 5, Schillerstrasse, Frankfurt-on-the-Main, in the
Empire of Germany, 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 for an improved anti-friction collar plate for vices has for its
object to provide a collar plate adapted to be interposed between the head of the
screw and the movable jaw of the vice to reduce the friction between the parts, and
consists of a collar plate formed on one side with nose pieces for bearing against
the jaw of the vice, and at the other side with a ball bearing against which the
head of the screw works.
In the accompanying sheet of illustrative drawings:

page_text: Fig. 1 is a front elevation of an anti-friction collar plate constructed according
to this invention.
Fig. 2 is a sectional side view of the same in combination with the screw of
a vice:
The collar plate a is furnished at the back with nose pieces or convexities c,
necessary for adjusting the vice, and in front with a ball race in which balls c
are placed, the ball race being closed by a steel bearing ring & that enters a
recess round the face of the collar, and is adapted to travel on the balls.
head of the vice screw bears against the ring & when transmitting the pressuro
of the screw through the ball bearing to the movable jaw of the vice.
The
A pin on the movable jaw of the vice engages between horns b in the collar
plate to prevent its turning with the screw.
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:
An anti-friction collar plate for vices consisting of a collar plate provided at
one side with nose pieces and at the other side with a ball race, bearing balls in
the race,
and a movable bearing ring closing the front of the ball race.
