Improvements in or relating to Vices.
I, EDWARD KAIN, of London Works, Bridge Street, Sheffield, in the County
of York, Engineer, do hereby declare the nature of this invention to be as fol-
lows:-
This invention relates to improvements in parallel or other vices and has for
its object to enable the jaws of the vice to instantaneously grip an article placed
between them.
To this end I take an ordinary parallel or other vice with the main screw held
in the outer part or jaw of the device, and on the back jaw at its back I fix by
suitable means any suitably-shaped box, the said box having a hole for receiving
a nut of the main screw carrying one or more projections the said projections
being milled toothed or otherwise provided with suitable indentations to engage
with one or more strips correspondingly milled toothed or indented in the box
so that when not engaged the nut can slide in the box forward or backwards at
will as may be desired.
The aforesaid strips are either screwed dovetailed or fixed in any suitable man-
ner, or may be cast in one with the box.
At the end of the main screw which I preferably turn down I may fix, fasten or
place a washer or collar having raised projections and on the back of the nut I place
corresponding projections or lugs to engage with the washer or arrange any other
suitable means to enable the collar and nut to act as a clutch one with the other
so that when tightening up the article placed in the vice the projection or pro-
jections on the nut comes immediately in contact with the strip or strips and
being correspondingly milled toothed or indented has a firm grip on the nut or vice;
but on slightly releasing the screw the washer or collar at the back of the screw
engaged with the projection or projections at the back of the nut causes the nut
to slightly turn and disengage with the strip or strips in the box thus allowing
the whole nut to slide within the box so that the jaws can be fixed at suitable dis-
tance from each other, according to their requirements.
It will therefore be quite understood that the space or hole in the box can be
made of any suitable size or shape so as to allow space for the nut of the main-
screw to oscillate and by so doing disengage the projection or projections on the
nut with their corresponding strips thus freeing the screw for a sliding motion.

page_text: I, EDWARD KAIN, of London Works, Bridge Street, Sheffield, in the County
of York, 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 relates to improvements in parallel or other quick-gripping vices
and has for its object an improved construction of the quick-gripping devices.
In the accompanying drawings
Figure 1 is a side elevation of an improved vice partly in section, constructed
according to this invention;
Figure 2 is a back elevation of the vice with its end cover removed.
Figure 3 is a plan of the grip nut and collar hereinafter referred to
Figure 4 being an end elevation of the same.
Like letters indicate like parts throughout the drawings.
This improved vice has jaws A and A¹ similar to those of an ordinary parallel
vice and on the back of the stationary jaw A¹ is fixed or fastened a box B having
an end cover B¹ and a hole or recess B², the latter extending through the box B
as shown.
. Within the hole or recess B2 is the screw C engaging with a nut D which has
projections D¹ upon it. On these projections DI teeth, serrations or indentations D
are formed of any desired shape, to engage in strips E which have teeth, serrations
or indentations corresponding with those D2 of the projections D¹, so that on the
rotation of the screw C in one direction the nut D and its projections D¹ move
automatically and interlock with the toothed strip or strips E. A spring or
springs G between the back of one or more of the nut projections D1 and the
opposite side of the box B will further ensure this interlocking action. The teeth 2
on the projection D¹ run freely over the teeth of the strips E when the jaw A and
screw Care pushed in endwise without the latter being rotated.
At the end of the screw C and beyond the nut D I fasten a collar F having a
projection or projections F1 on its inside to engage with projections or lugs D³
on the nut D, the collar and contiguous portion of the nut acting as a clutch 3
when the screw C is unscrewed.
Thus it will be readily understood that when the article is placed between the
jaws A and A¹ and the screw C is turned for tightening them up, the friction on
the screw C of the nut D causes the projections D¹ and teeth D2 to interlock with
the strip or strips E and thus causes an almost instantaneous connection of the 3
nut with the box B. If necessary, if the friction of the nut D is not sufficient
on the screw C, I may use the spring or springs such as G for assuring an im-
mediate grip. Now in the case of releasing, the screw C is turned in the opposite
direction which causes the collar or washer F with its projection or projections F¹
to come in contact with the corresponding lugs or projections D³ of the nut D and 40
disengages the projections D¹ and teeth 12 from the strips E enabling the jaw A
and screw C to be pulled out endwise freely. Any number of teeth, serrations
or indentations D2 or projections D¹, or corresponding strips E can be used; the
latter are fastened into the box B or cast in the same or any means may be adopted
for the washer or collar F to engage with the nut D when rotated in one direction 45
and to disengage from it when rotated in the opposite direction and enabling the
nut D and its projections D¹ to oscillate in and out of gear according to the direc-
tion of rotation of the screw C.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
(1) In a vice the combination with the screw C of a nut such as D toothed or
indented and a toothed or indented strip such as E arranged and operating sub-
stantially as and for the purpose described.
(2) In a vice the combination with the screw C of a nut such as D toothed or
indented, a collar or head such as F adapted to act in conjunction with the nut
as a clutch, and a toothed or indented strip such as E arranged and operating
substantially as and for the purpose described.
(3) The combination and arrangement of parts constituting the complete quick-
gripping vice substantially as and for the purpose described and illustrated in the
accompanying drawings.
