IMPROVEMENTS IN THE CONSTRUCTION OF TUBE VICES
Year: 1885

page_text: I CHARLES NEIL Campbell Works, Bridge Street, Sheffield in the County of
York Engineers Tool Maker do hereby declare the nature of my said invention for.
IMPROVEMENTS IN THE CONSTRUCTION OF TUBE VICES to be as follows:-
My invention relates to improvements in the construction of vices for holding
tubes pipes, and similar work and which are generally known as Tube Vices its
object being to make then of a more convenient form for the purpose required, of
less weight better adapted for general use.
In carrying out my invention I make the two jaws of the vice preferably of
chilled cast iron or steel, with the gripping teeth cast on at the time, but if found
desirable I. may attach steel faces to one or each part.
The bottom jaw which is generally made so as to be screwed down upon a bench,
is divided transversely across the V of the jaw, by a slot of sufficient width to
admit of two bolts being passed through, and so that they may be moved sideways.
Two recesses are made in the underside to receive the heads of the bolts which are
rounded or T shaped to enable the bolts to be moved upon them as upon a fulcrum.
If preferred the bolts instead of the head described may be made with an eye,
through which (and the sides of the bottom jaw) a pin may be passed, and on
which they can turn in the beforementioned slot.
Upon the projecting screwed parts of the bolts are suitable nuts for screwing
down the top or loose jaw, which consists of a cross head, and the jaw proper
depending from the cross head, both cast in one piece. The jaw portion is toothed,
and can pass freely down the slot and between the divided bottom jaw, to enable
the vice to grip the smallest sizes. Open end slots are made in the crosshead to
receive the bolts beforementioned, and I incline the top surface of the crosshead on
which the nuts rest, so that there shall be no tendency of the bolts to slip out of
the slots When required for use, the bolts can be moved sideways and instantly
disengaged from the slotted crosshead. This arrangement enables me to construct
Tube Vices of much less weight and bulk than usual

I, CHARLES NEIL Campbell Works, Bridge Street, Sheffield, in the County of
York Engineers Tool Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION OF TUBE VICES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement, that is to say :-
My invention relates to improvements in the construction of Vices which are
chiefly used for holding gas piping and other similar tubing and round work, and
are known as Tube Vices; the object being to make a more convenient form of
vice for the required work, and of less weight than those usually made.
And in order that my invention may be clearly understood, I annex a sheet of 1
drawings illustrating a Vice of my improved construction, the same letters of
reference indicating the same parts in any of the figures in which they occur.
Fig. 1, is a plan or top view of a Vice made according to my invention.
Fig. 2, is a side elevation of same.
Fig. 3, is a separate view of the loose jaw.
Fig. 4, is a front elevation of a Vice with the jaws swivelled round so as to hold
a pipe horizontally.
In carrying out my invention, I make the two jaws A and B, preferably by
casting them of chilled cast iron, or of steel, the gripping teeth being formed in
the moulding, but if found desirable, the jaws may have loose steel faces with
cut teeth, attached to them.
'I attach the back jaw A to a standard C which may be of cast iron, provided with
bolt holes to enable it to be screwed down to a bench, on to a suitable metal standard,
or to legs. I make the back jaw with a pap or projecting boss D, slightly coned to
fit into a corresponding recess formed in the standard before mentioned, and which
may readily be secured by means of a bolt and nut E, but this is not a material
part of my invention being simply to secure the jaws in any desired position to suit
the work; thus in Figa 1 & 2 the jaws are horizontal so as to hold the pipe F in a
vertical position, while in Fig. 4, the jaws are vertical, and the pipe is horizontal.
In the back jaw A, two semicircular recesses G are formed, to receive the heads
of the two bolts H, which have a limited movement sideways in the central slot or
opening I, which alot divides the jaw into two parts J and J2, this movement is
shown by the dotted lines in Fig. 1.
The loose jaw, B, shown in Fig. 3 fits loosely between the parts J & J* when
screwed up for small tubes, and is provided with two open end slots K K, which
fit upon or over the bolts H, in such a manner that when it is desired to release
the work held in the vice, it is only necessary to slacken the nuts L, turn back the
bolts to the position of the dotted lines, which at once sets the jaw B at liberty.
