I RICHARD MELHUISH of 85 and 87 Fetter Lane, in the City of London, Engineer,
do hereby declare the nature of my said invention to be as follows:―
.
The object of my invention is to manufacture a cheap, simple, and convenient form
of Joiner's parallel vice.
The fixed jaw of my improved vice is furnished with a bracket or projection, so.
formed that it may be firmly secured to a bench or other fixture. This bracket may
be formed so as to be secured to the front vertical face of the bench, or let into the.
same; or the bracket may be so formed that it may in like manner be secured to the
underside of the bench top, or board, or other fixture. The bracket has a wide
rebated or dovetail groove, in which a slide, forming part of the movable jaw, slides.
This slide is of U form, in section, and encloses the screw, and also carries the
movable jaw. The head of the screw is outside the movable jaw, and is fitted with an
ordinary sliding bar for turning the screw. A snug is fitted to the boss of the
movable jaw, which enters a groove in the screw head to prevent the screw leaving
the movable jaw.
A nut is fitted to the fixed bracket by a snug which drops into a boss or hole in the
bracket, and in which nut the long screw works, and whereby also the movable jaw is
operated.

page_text: I RICHARD MELHUISH, of 85 and 87 Fetter Lane, in the City of London, Engineer,
do hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement :-
V..
The object of my invention is to manufacture a cheap, simple and convenient forma
of Joiner's parallel vice.
The fixed jaw of my improved vice is furnished with a bracket or other suitable
projection so formed that it may be firmly secured to a bench or other fixture. This
bracket may be formed so as to be secured to the front vertical face of the bench, or
let into the same; or the bracket or other extension of the fixed jaw may be so
formed that it may in like manner be secured to the top or the underside of the bench
top or board, or other fixture.
The bracket has a wide, rebated, or dovetailed groove, in which a slide, forming
part of the movable jaw is free to slide. This slide is preferably of U form, in
section, and encloses the screw, and also carries the movable jaw. The head of the
screw is outside the movable jaw, and is fitted with an ordinary sliding lever bar for
turning the screw. A snug or a flange, or other well known device, is fitted to the
movable jaw to prevent the screw drawing out of the same.
AT nut is fitted to the fixed bracket by a projecting snug which drops into a boss
or hole in the bracket, and in which T nut the long screw works, and whereby also
the movable jaw is operated.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a perspective front elevation of my invention. Fig. 2 is a back elevation,
partly in section. Fig. 3 is an enlarged. section, on the line 1-2 and Fig. 4 is an
enlarged plan of the nut.
a is the fixed jaw. b is a bracket or extension, cast in one with the fixed jaw, and
having screw holes e c or other provisions for securing the same to a bench or other
article. d is the movable jaw. e is a slide cast in one with the movable jaw, the form
of which is shown in Fig. 3. f is a long screw passing through the movable jaw d,
and engaging in the screw nut g. h is a boss formed in the bracket b, having a hole
for receiving the snug & whereby the nut is held in position.

m is a flange formed
upon the screw to keep the movable jaw to the head of the screw, when opening out
the vice..n is the head of the screw, and o is the ordinary sliding lever bar.
The head of the screw may be formed with a flange or shoulder on the outside of
the movable jaw, such flange being covered in and held to the jaw by a plate screwed
to the jaw or such shoulder and plate may be fitted on the inner side of the jaw;
for securing the position of the jaw relatively to the screw.

page_text: It is obvious that various modifications may be made in the relative sectional forms
of the fixed bracket 6 and the slide e so as to effect the object hereinbefore
described, viz. the free sliding action of one in or upon or in relation to the other,
for the purpose of ensuring the parallelism of the jaws.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
The manufacture and use of the improved Joiner's parallel vice, having a fixed
jaw a and bracket b movable jaw d and slide e, screw f working in the screw nut g
held in position by the snug k, the several parts being combined and operating sub-
stantially as herein before described and shown on the drawings.
