PROVISIONAL SPECIFICATION.
Improvements in Vices and in Means for Operating same.
I, JOSEPH FOULDS of Chapel Street, Nelson-in-Marsden, Lancashire, Clog Maker
do hereby declare the nature of this invention to be as follows, that is to say:
.
It relates to improvements in vices and in means for operating same and consists of
constructing and arranging the parts thereof in such a manner that their efficiency is
greatly enhanced.
This is attained by making the back in contradistinction to the front, jaw of the vice
moveable, motion being imparted to said back jaw by means of a coarse spiral shaft or
screw to which it (said jaw) is coupled by means of a screwed block part in the
common and well known manner.
Motion is imparted to this screw by means of a segment rack and pinion arrange-
ment which is made so that it may be operated in one direction by a pedal device and
in the other by a spring which enables the user, when he wishes to place an article
within the grip of the vice of such a weight as to necessitate the engagement of both
his hands, readily to do so by means of one of his feet as will be well understood.
In order to give additional grip to the article when it has thus been placed within
the vice as also to rigidly lock same within said grip, a supplementary screw is
mounted with the vice's sleve at the outer end of and in a straight line with the coarse
screw above described, the outer end of said supplementary screw abutting against
the outer end of the vice's sleve to which it is attached to be withheld from
revolving.
Upon this supplementary screw is mounted a screwed boss to which is attached a
suitable bandle, said boss having its end that reaches up to the outer end of the coarse
screw formed larger and the outer end surface of this enlarged part is somewhat
serrated, said serrations being made to suit the serrations of a similar boss that is
rigidly attached to the outer end of the coarse screw in such a manner that they will
gear together so that when the handle of the screwed boss is rotated the coarse screw
is similarly rotated which gives the additional grip and by the actions of said screwed
boss against said coarse screw and against the screw upon which it is mounted, the
same acts as a lock or check nut with the desired result.

COMPLETE SPECIFICATION.
Improvements in Vices and in Means for Operating same.
I, JOSEPH FOULDS of Chapel Street, Nelson-in-Marsden, Lancashire, Clog Maker,
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, that is to say :-
It relates to improvements in vices and in means for operating same and consists of
so constructing and arranging the parts forming these said vices and their operating
mechanisms that the operations thereof are greatly facilitated while the efficiency of
said vices is considerably enhanced, and in order that my said invention may be more
readily understood, I have hereunto appended sheets of drawings illustrative thereof,
to which by figures and letters reference is made in the following description.
Fig. 1 is part sectional side elevation of my improved vice, and fig. 2 is front
elevation of enma

page_text: Fig. 3 is side elevation shewing the pedal arrangement. Fig. 4 is a top view o
parts shewn by fig. 3. Fig. 5 is side view of the pedal and support for same.
Fig. 6 is a detail drawing hereinafter referred to.
Figs. 7 and 8 are illustrative of modifications hereinafter explained.
The object of this invention is attained by making the back jaw a movable, while
the front jaw is fixed, and imparting motion to said jaw a by means of the coarse
spiral shaft or screw c which passes through and is coupled to so as to operate the
boss part a formed on or attached to the jaw a.
The
The screw c is operated by means of the segment rack d operating the gear wheels e e
which impart motion to the wheel frigidly mounted upon the said screw c.
rack d is operated in one direction by the spring g while by pressure being imparted
to the outer end of the pedal k in the direction indicated by the arrow has by
the foot of the operator being placed thereon, said rack d through the medium of
the rod is operated in the other direction, this latter direction preferably being the
one by means of which the jaw a is brought by its screw c to press against the
jaw and so that when the foot of the operator is removed from the pedal k
the spring will cause the jaw a to recede from contact with the jaw b, this arrange-
ment enabling the user, when he wishes to place an article within the grip of said
jaws a and of such a weight as to necessitate the engagement with said article
of both his hands, readily to do so by means of one of his feet as will readily be
understood.
boss
As
In order to give an additional grip to an article when it has been placed between
the jaws a and b as also to rigidly lock said jaws together so that when the foot
of the user has been removed from pressing upon the pedal the jaw a shall still
be held so that the spring 9 cannot cause it to recede or move from this position,
the boss m having a serrated outer end m¹ and a handle m" is mounted loosely
upon the outer end of the screw c which at this part has no thread formed upon it..
The serrated end m³ of the boss m operates in connection with the serrations
formed on the edge or side of the collar c which is rigidly attached to the screw c,
when said boss m is moved by its handle m¹ so as to rotate upon the screw c and
cause its projections nn' to leave the recesses o o¹, (fig. 6) formed for the reception
of said projections n n' respectively, and mount the respective portions p p¹ of
formed upon the parts which forms the support for the outer end of the screw c.
will be seen when the boss m is rotated by its handle m", as above described, so soon
as the projections an¹ begin to mount the projections pp' the serrations m¹ on said
boss m will begin to move into gear with the serrations formed upon the collar c and
after these parts n n' have been moved sufficiently far to be in contact with the outer
surfaces of the projections p p¹ said serrated parts will be properly in gear with each
other and will; remain so until the direction of motion of the boss m is reversed or
continued so that the projections n' formed thereon shall come into proper relative
positions with the recesses o o¹, when they will be again liberated from gear, however
by the continued movement of the boss m after it has been brought properly into gear
with the serrated collar c!, the screw c is partly rotated by which means the jaw a is
more firmly pressed in the direction of or against the jaw b so that in this way an
extra grip may be had of the articles held by said jaws, and this extra grip serves to
lock the jaws in this position.
In order to cause the boss m to recede from contact with the collar c when.it.(said
boss) has been moved so that its projections nn' are opposite the recesses o o¹, a suitably
inclined part is formed on the edge of the sleeve u by which means when the
handle m 77211 comes in contact therewith so as to be operated thereby, the object. desired
is accomplished.
Instead of an opening being made in the upper surface of the sleeve u for the
passage of the part a' which attaches said jaw a to its screw c as is shewn by fig. 4,
the jaw a may have its part a' constructed that suitable openings for the passage. of
same may be made in the sides of said sleeve u as shewn by fig. 7.
Again instead of the rack d being made to operate the screw c by means of gearing
wheels mounted near the jaw end of the vice as hereinbefore described, it may be

page_text: arranged so that it will operate said screw c by gearing directly with the pinion c*
(fig. 8) which forms also the serrated collar and is at the outer end of the sleeve u
The positions of the pedal k and its support being arranged to suit this said
alternative arrangement of parts for imparting motion to the screw c.
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 :-
1. In a vice the combination of a moveable back jaw with a stationary front jaw,
said moveable jaw being operated by means of a pedal, gearing wheels and a screw
substantially as specified.
2. In a vice the combination of a moveable back jaw and means for locking same
in position substantially as set forth.
3. The construction and arrangement of parts formning a vice as specified, in such a
manner that same may be operated substantially as herein set forth.
