IMPROVEMENTS IN PIPE VICES
Year: 1884

page_text: I JOHN CHARLES BAUER of 11 Comerford Road, Brockley in the County of
Kent, Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN PIPE VICES to be as follows:-
In carrying out my invention I employ short pieces of steel toothed at one end,
and pivoted at the other to a connecting body or link in such a manner that when
the pipe or other article to be screwed is placed between the toothed parts which
form the vice jaws and are opposite to one another, it is firmly held by them on
account of the leverage brought to bear upon the pivot at the other end.

page_text: I JOHN CHARLES BAUER of 11 Comerford Road, Brockley in the County of
Kent, Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN PIPE VICES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
In carrying out my invention I employ short pieces of steel (or iron) toothed at
one end, and pivoted at the other to a connecting body or link in such a manner
that when the pipe or other article to be operated upon is placed between the
toothed parts which form the vice jaws and are opposite to one another, it is firmly
held by them on account of the leverage brought to bear upon the pivot at the
other end.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing which represents views of
Pipe Vices constructed according to my invention.
Similar letters in all the figures represent similar parts.
In figures I. II and III, a and a¹ are short pieces of steel or iron, toothed at one
end as shewn in the drawing and pivoted at the other end c to the connecting body
or link b which is provided with an angular seating d for the pipe e or other article
to rest in. As the toothed parts of the aforesaid pieces of steel or moveable jaws a
and a form an excentric arc f so that the points of contact fare of varying
distance from the pivot c, it follows that the said moveable jaws a and a¹ will, on
being pushed aside, not only admit pipes &c. of various sizes being placed into the
angular seating d, but will also securely hold such pipe or other article and prevent
its turning one way or the other until released by simply pushing the said moveable
jaws again aside. To admit of still larger pipes &c. being placed into the vice
some extra holes c¹ are provided to hold the pivot or pivots c in a different
position. The foot or base plate b₁ forming a part of the vice is to enable its being
conveniently fixed to a work bench. Fig. IV represents a transverse section of
the same.
Figures V, VI and VII represent a side elevation, an end elevation and a plan of
another shape of my Pipe Vice working on a similar principle to the one above
described but having the toothed part of the moveable jaws on the inner side as
shewn in Figure VIII, instead of externally as shewn in Figure I of the
accompanying drawing.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is performed, I declare that what
I claim is:
Firstly. A self-gripping Pipe Vice having one or more moveable jaws pivoted to
the body of the vice, and shaped at the opposite side to the pivot in such a manner
that the distance from the said pivot to such opposite side or parts thereof,
increases or diminishes as the said jaw is being moved on its pivot on way or the
other.
