PROVISIONAL SPECIFICATION.
Improvements in Devices or Clamps for Holding Pipes or other
Round or Awkwardly Shaped Articles in Vices.
We, HARRY CLAYTON SHAW of Mill Brow, Sutton, St. Helens in the County
of Lancaster, Manager of Chemical Manure Works, JOHN CRONE and DAVID
CRONK TAYLOR both of Sutton Oak in the County of Lancaster, Chemical
Manure Manufacturers do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object the enabling of the ordinary vice to be used
instead of a pipe vice or other implement.
On the vice jaws we place in any convenient manner a pair of clamps. These
clamps have preferably lugs at each end with set screws by which they can be
screwed to the vice jaws. These clamps for use with pipes have a longitudinal
✓ groove horizontal along their centre line. They have also two or three
✓ grooves of varying size placed perpendicularly, the V grooves of one clamp
being opposite the V grooves of the other.
It is obvious that where other shapes than round are wanted clamps of this
nature can be made to suit them.
The clamp can be made of steel or other suitable material. It may have a
flange resting on the top of the vice or not as desired.

Improvements in Devices or Clamps for Holding Pipes or other
Round or Awkwardly Shaped Articles in Vices.
We HARRY CLAYTON SHAW of Mill Brow, Sutton, St. Helens, in the County
of Lancaster, Manager of Chemical Manure Works, JOHN CRONE and DAVID
CRONK TAYLOR both of Sutton Oak in the County of Lancaster, Chemical
Manure Manufacturers 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 has for its object the enabling of the ordinary vice to be used
instead of a pipe vice, or other implement, and it will be best understood by aid of
the accompanying sheet of illustrative drawings on which
Figure 1 is a view of part of a pair of vice jaws, having the improved clamps
adapted to them and Figure 2 is a horizontal section of one of such clamps on
its jaw.
To the vice jaws A A, we place in any convenient manner a pair of clamps B B.
These clamps have preferably lugs C C at each end with set screws D D by
which they can be screwed to the vice jaws A A. These clamps for use with
pipes have a longitudinal V groove E, horizontal along their centre line. They
have also two or three V grooves F F F of varying size, placed perpendicularly,
the grooves of one clamp being opposite the V grooves of the other.
It is obvious that where other shapes than round articles are to be held, clamps
with grooves of a corresponding shape can be made to suit them, and the number
of grooves need not be limited to two or three, such being cited as a convenient

page_text: number, and in some cases it may be preferred not to provide set screws D D, but
to simply allow the clamps to rest on the vice jaws by the flanges G G, and they
would be sufficiently held there by the action of twisting up the vice to hold the
article in the clamps.
The clamp can be made of steel or other suitable material.
H are simply depressions, caused by casting in the course of manufacture.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is: :-
1. The improvements in devices or clamps for holding pipes or other round or
awkwardly shaped articles in vices, which consists in forming them of pieces B B,
capable of application to the jaws of a vice with suitable grooves substantially as
described in which the articles can be held on the screwing up of the vice,
substantially as hereinbefore set forth.
2. The improved devices or clamps, for the purpose specified, substantially as
herein before described and shown on the accompanying sheet of drawings.
