Improvements in Vice Jaws and Clamps.
JAMES SWALWELL 29 Godfrey Road Newport, Mon. Manager of Works, do hereby
declare the nature of this invention to be as follows:-
This invention is intended to facilitate the changing of the angle, & to make it
more convenient to deal with, any class of work for which Vice Clamps are used; and
consists of pivoting the clamps opposite each other, upon studs or pins. Such studs
or pins being either fixed to the back of the clamp and pivoted in a hole formed in
the Vice Jaw, or, fixed in an ordinary sheet iron vice clamp and the swinging clamps
mounted on them. The clamps are made in metal or wood, or with metal shells
filled with wood or other material suitable for the class of work to be done. They
may be made any shape, circular or otherwise, with their faces cut in grooves or other
forms to suit the shape of the articles that are to be fixed therein. Clamps suitable
for tubing are preferably made circular with grooves cut across their faces, suitable
for different sizes of tubing, any of which grooves can be used with equal facility.
That which I consider novel in this invention, is making vice jaws with a hole or
recess in their faces to receive a pin fitted to a clamp of any desired shape, such pin
acting as a pivot upon which the clamp is swung. Also fixing on an ordinary pair of
vice clamps a stud or pin upon which clamps of any desired shape are mounted
substantially as herein described.
Dated this 22nd day of December 1896.
JAMES SWALWELL 29 Godfrey Road Newport Mon. Manager of Works 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 is intended to facilitate the changing of the angle and to make it
more convenient to deal with any class of work for which Vice Clamps are used and
consists of pivoting the clamps opposite each other upon studs or pins such studs or
pins being either fixed to the back of the clamp and pivoted in a hole formed in the
Vice Jaw or fixed in an ordinary sheet iron vice clamp and the swinging clamps
mounted on them. The clamps are made in metal or wood or with metal shells filled
with wood or other material suitable for the class of work to be done. They may be
Imade any shape circular or otherwise with their faces cut in grooves or other forms to
suit the shape of the articles that are to be fixed therein. Clamps suitable for tubing
are preferably made circular with grooves cut across their faces suitable for different

consider novel in this invention is making vice jaws with a hole or recess in their
faces to receive a pin fitted to a clamp of any desired shape such pin acting as a pivot
upon which the clamp is swung also fixing on an ordinary pair of vice clamps a stud
or pin upon which clamps of any desired shape are mounted substantially as herein
described.
My invention is illustrated in the accompanying drawings in which
Fig. 1 is a view shewing how clamp is affixed to vice jaw a by pin d.
Fig. 2 is a part full and part sectional view shewing movable clamps b affixed to
ordinary vice clamps a 1 shewn fitted to vice jaw a.
Fig. 3 is a front elevation of one clamp.
Fig. 4 is a plan of a pair of octagonal movable clamps complete shewing grooves
of different forms.
Having now particularly described and ascertained the nature of said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1. Mounting vice clamps opposite each other, free to turn on studs or pins formed
on the back of the clamps and pivoted in holes formed in the Vice Jaws to receive
them.
2. Mounting vice clamps free to turn on pins formed or fixed on ordinary sheet
iron clamps substantially as and for the purposes herein before described and
ascertained.
