Vices, also applicable to Slide Rests.
We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm Thomas
Glover and Company, Limited, 214 to 222, St. John Street, Clerkenwell, London,
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved single or double traverse self-centreing paral-
lel vice also applicable to slide rests.
The objects being:
1st. Economy in production and increased efficiency.
2nd. The apparatus is rendered self cleaning, all operative mechanism being
entirely enclosed and concealed.
In carrying out our invention, we arrange a short worm centrally in a cavity
of the traverse bed which but for this cavity is perfectly plain, having no slots
or holes, all the hollowing required for lightness being underneath. The worm
before mentioned is bored, and a spindle is centrally arranged therein and pro-
jects through a cored hole in the bed far enough for a handle to be placed on either
end. The worm is fixed to this spindle by a pin or otherwise. The slide that
works upon this traverse bed has a rack cast or fitted to it on the underside for
engagement with the aforementioned short worm which is thereby covered from
end to end of the traverse. The slide has a traverse bed formed at right angles
to that of the first named, and is fitted with worm spindle and rack in the same
manner, the slide that it traverses being fitted with a pair of vice jaws with a
rack cast or fitted to the underside for engagement with a right and left handed
worm respectively, these being both fitted on one spindle for operation by a handle
from either end.
The end thrust is taken by the worm and not by the spindle. The spindle is
entirely enclosed and need not be finished bright, except the projecting ends.
These ends are centralised in the cored hole by glands.
This vice is especially applicable for use on a drilling machine or a planing
machine, as in the former case any number of holes, no matter how they may
be disposed, can be brought under the drill, and in the latter, no matter how it
may be covered with tool dust and shavings, it is always self cleaning when
traversed and no dirt can get to the operative screw.

Vices, also applicable to Slide Rests.
We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm Thomas
Glover and Company, Limited, 214 to 222, St. John Street, Clerkenwell, London,
Engineers, 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 relates to improved single or double traverse self-centreing paral-
lel vice, also applicable to slide rests.
The objects being:
1st. Economy in production and increased efficiency.
2nd. The apparatus is rendered self cleaning, all operative mechanism being
entirely enclosed and concealed.
In carrying out our invention, we arrange, as represented in the annexed draw-
ings, a short worm centrally in a cavity of the traverse bed which but for this
cavity is perfectly plain having no slots or holes, all the hollowing required for
lightness being underneath.
The worm before mentioned is bored, and a spindle is centrally arranged therein
and projects through a cored hole in the bed far enough for a handle to be placed
on either end.
The worm is fixed to this spindle by a pin or otherwise. The slide that works
upon this traverse bed has a rack cast or fitted to it on the underside for engage-
ment with the aforementioned short worm which is thereby covered from end
to end of the traverse. The slide has a traverse bed formed at right angles to-
that of the first named, and is provided with worm spindle and rack in the same
manner, the slide that it traverses having a pair of vice jaws with a rack cast
or fitted to the underside for engagement with a right and left handed worm
respectively, these being both fitted on one spindle for operation by a handle from
either end.
The end thrust is taken by the worm and not by the spindle.
The spindle is entirely enclosed and need not be finished bright, except the
projecting ends. These ends are centralised in the cored hole by glands.
This vice is especially applicable for use on a drilling machine, or a planing
machine, as in the former case any number of holes, no matter, how they may be
disposed, can be brought under the drill, and in the latter, no matter how it may
be covered with tool dust and shavings, it is always self cleaning when traversed
and no dirt can get to the operative screw.
Our invention will be clearly understood by the following taken in conjunction
with Figure 1 part sectional elevation, Figure 2 plan of a single sliding or mov-
able jaw vice, Figure 3 end elevation, Figure 4 plan of double sliding or movable
jaw vice for an ordinary bench for ordinary traverse motion only.
Figure 5 front elevation, Figure 6 end elevation of a duplicate actioned vice
applicable to a lathe bed or the bed of a drilling machine, and in which either
single sliding jaw or double sliding jaws can have a motion at right angles to
each other for adjustment of the article being operated upon, the position of the
vice being adjustable over the slot of the bed by a sliding action and a tightening
by the usual under fly nut. Figure 7 front elevation, and Figure 8 end elevation
of a multiple vice as fitted to slide by worm and spindle located in the bed of
the lathe or drilling machine for operating the multiple vice mechanically, or as
desired.

page_text: Referring to Figures 12 and 3, A is the fixed jaw secured to a bench B by
the usual bolts or screws C, C, said jaw having a long and plain projection D in
which is a recess E for a short worm F, and a long hole G for the short and en-
closed worm spindle H, the worm being fastened thereon, so that when the
spindle H is turned by the handle I, the short worm rotates with it. The top
surface of this extension is plain.
Kis the sliding jaw retained in contact with the extension by ordinary V
block L. M is a rack in the central under face into which the short worm F
is in gear and by which it is moved as aforesaid.
According to the modification, Figure 4, the bed N is separate from both jaws
which in this construction or arrangement are both movable away from each
other equally by the right and left hand short and enclosed worms which are
both on the spindle and also enclosed, as explained with reference to Figures 1
and 2.
Figures 5 and 6 show a double operating device, the lower of which is slightly
modified of that shown at Figures 1, 2, and 3, the change being- that instead of
the jaws A and K, another traverse bed P mounted on base Q is operable by the
spindle H and worm, said bed having the base 1" of the duplicate device secured
to it by the bolts R, R, and with its spindle H¹ and worm F¹ enclosed for operating
it at a right angle for adjustment purposes after the bottom base Q has been set
by the fly nut and screw in the slot of the lathe bed.
We have for convenience in Figures 5 and 6 shown a grip S and pinch
screws S1, S1, for holding a tool.
Figures 7 and 8 represent the same device affixed to a saddle T of a screw
cutting lathe.
If the spindle H be long enough to project from both ends of double centreing
vice, and a square be on each end, the turning handle can be shifted for operation
as desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. The hereinbefore described improvements in single and double traverse_self-
centreing parallel vices, also applicable to slide rests consisting of an enclosed
spindle, and enclosed worm for operating a rack or racks, as and in the manner
represented on the annexed drawings.
2. Constructing the operating gear i.c. the enclosed short worm F and enclosed
spindle H in a traversing bed for engaging a rack M of the adjustable jaw K or
grip, as and for the purposes described and substantially as shown.
