PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Securing Material to the Tables of
Shaping and other Machines.
We, JOHN RICHARD ROBINSON, of Beech Hill, Cardigan Lane, Leeds, in the
County of York, Commercial Traveller, and EDGAR RHODES, of 17, Springfield
Place, Leeds, aforesaid, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object, the construction of an apparatus whereby, metal
and the like, may be held secure on the table or other support in the desired
position, whilst being cut by the tool of a shaping or other machine.
1
We accomplish our object in the following manner-The apparatus is applicable
to the jaws of parallel vice used for holding metal or other material whilst being
cut, or it may be independent of the vice and secured to the machine table or other
support by bolts; and consists in forming on each vice jaw, or on separate blocks,
a hinged jaw centred on a pin acting as a fulcrum, the jaw being by preference
provided with a cut facing for holding the material to be operated upon.
On nipping the material to some extent between the jaws by the vice screw, or
placing it between the separate blocks secured to the table or other support, the
material is finally secured by tightening screws passing through some portion of the
hinged jaw, by which the face of the same is caused to grip the material and at
the same time press it downwards on to the table or other support firmly.
Dated this 28th day of October 1890.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Securing Material to the Tables of
Shaping and other Machines.
We, JOHN RICHARD ROBINSON, of Beech Hill, Cardigan Lane, Leeds, in the
County of York, Commercial Traveller, and EDGAR RHODES, of 17, Springfield
Place, Leeds, aforesaid, Engineer, 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 construction of an apparatus whereby metal
and the like may be held secure on the table or other support in the desired position
whilst being cut by the tool of a shaping or other machine.
In the accompanying drawings
Fig. 1 represents a side elevation partly in section of a parallel vice suitable for
attachment to the table of a shaping or other machine.
Fig. 2 is an end view of the same.
Fig. 3 a plan of the parallel vice.
Fig. 4 shows an arrangement for utilizing our improved vice jaw in combination
with an angle plate.
Fig. 5 is a side view of a screw parallel vice having one jaw constructed according
to our invention and
Fig. 6 is a plan of the same.
The apparatus is applicable for holding metal or other material secure to the
machine table, face plate or other support whilst being cut, and is attached thereto
by bolts. On placing a piece of metal between the jaws of a pair of vice con-
structed in accordance with the arrangement shown by Fig. 1. the sliding
[Price 6.]

page_text: blocks A. A. are moved so that the face of the vice jaws B. B. are in contact with
the material between them; the sliding blocks A. A. are then fastened in that
position and the material finally secured between the jaws B. B. hinged to the
respective blocks A. A. on fulcrum pins C by operating the screws D. D.
On turning the screws D. D. so that the lugs at E. E. are elevated, the jaws arc
moved on the fulcrum pins C. C. thus by the radial movement of the jaws, the
material is gripped and at the same time pressed in a downward direction on the
base plate G. thereby securely holding it between the jaws and firm in contact with
the base plate G. so that the springing of the material during the operation of
cutting and the tendency of it to rise when secured by a parallel vice of the ordinary
construction is obviated.
When using one or more of our improved hinged jaws in connection with an
angle plate H. and operating the jaw or jaws in the manner as before described, the
material is held secure against the angle plate and tight on the table or other
supporting plate.
Our improvement is also applicable to parallel vice having a fast and movable or
sliding jaw in the drawing only one jaw is provided with our improvement, but it
will be easily understood by ironworkers and others accustomed to the use of
parallel vice, that both jaws may be hinged, and the material between the jaws
secured and pressed in a downward direction on operating the screw or screws D
passing through lugs E.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same may be performed, we declare that what we
claim is :-
A block A or other support to which is hinged on a fulcrum pin C. a vice jaw B.
in such manner that material is secured between the jaws by a screw D passing
through a lug E all arranged substantially in the manner as shown and hereinbefore
described.
