Complete Specification Left, 2nd Mar., 1897-Accepted, 3rd Apr., 1897
We, EDWARD KAIN of London Works, Bridge Street, Sheffield, Engineer and
ARTHUR THOMAS PEARSON of 46 Rutland Street, Sheffield, Engine Fitter, both
in the County of York, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement 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 we take an ordinary parallel or other vice with the main scrow held
in the outer part or jaw of the vice and ou the back jaw at its back we fix by
suitable means a square or other shaped box preferably having a hole for receiving
the nut of the main screw on which is formed a suitable projection at its bottom
which passes or slides forward and back at any required distance in a groove in the
bottom of the box.
At the end of this box we preferably fix a cover or suitable projection and
between this projection and the back jaw of the vice we place a hollow barrel
screwed or grooved as may be required. The bearing of this barrel is arranged
eccentrically so that on turning it, it comes in contact with the projection on the
but which is also either screwed or grooved to suit the aforesaid screw or groove
of the barrel.
And through the outside part or jaw underneath the main handle of the sorew of
the vice we make a hole to carry a small rod having a square end which passes
through the hollow part of the barrel.
On the outside of the rod at the outside jaw end we attach a suitable handle,
lever spring or other arrangement, by operating which the screwed or grooved
barrel is turned on its eccentric bearings into its position on the projection part of
tho inain nut, and instantaneously locks it in position; when not in engagement with
this projection, the jaw of the vice can be slid out or pushed in so as to take a
suitable article within its jaws, and once fixed the screwed or grooved barrel is
brought in contact with the projection on the nut which immediately locks it.
We may also use a rack with lever or other arrangement to come in contact
with the projection on the main nut which projection is made to suit the rack,
instead of the aforesaid eccentrically fixed grooved or screwed barrel.

page_text: We, EDWARD KAIN, of London Works, Bridge Street, Sheffield, Engineer, and
ARTHUR THOMAS PEARSON, of 46, Rutland Street, Sheffield, Engine Fitter, both
in the County of York, 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 parallel or other vices, of the quick-gripping kind.
In the accompanying drawings..
Fig. 1, is a perspective view of our improved vice partly in section;
Fig. 2, is a rear-end elevation of the box of the same.
Like letters indicate like parts throughout the drawings.
lu the example illustrated we employ an outside jaw A, with slide or bar B,
an inside jaw C, and a screw D, such as are generally constructed for parallel
vices.
At the back of the inside jaw C we form a box of any desired shape E having a
flange E' preferably bolted to the same plate F, as that which carries the said
jaw C.
The box front fits up against the back jaw C, or is cast together with it if
necessary. Within the box E we form a groove or slot G¹ and place in the slot a
suitable out G to fit the screw D, the said nut G having a projection G³ preferably
extending from its base and suitably grooved to engage with the barrel H which
is also grooved or screw-threaded to suit. The ends of the barrel H are
preferably turned down eccentrically to the said barrel and are received in suitable
bearings K K' within the box E.
Through the said barrel H we form a hole of any suitable shape, preferably
square, receiving a rod M part of which is made to fit the hole in the barrel so that
it may slide therein during its movement with the jaw A, but cannot be rotated
without rotating the barrel.
N is a spring encircling the rod M between the jaws A and C and also engaged
with both as to keep the rod from moving eud wise in the jaw A and to tend
'always to turn the rod M in such a direction as to keep the barrel H in gear with
the projection G of the nut G.
O is a small lever fixed on the rod M and serving to control it and also acting
in conjunction with the spring N to prevent it from moving endwise in the
jaw A.
It will readily be understood that directly the lever O is brought close to the
screw D it turns the barrel H on its eccentric bearings K K' sideways i.e. eccentri-
cally out of engagement with the grooves of the projection G of the nut G and
enables the outside jaw A. and the disengaged nut G to slide out or in as may be
required to suit the size of the article to be held within the jaws A and C. The
article can be instantly gripped by pushing the jaw A to meet it and allowing
the lever to fly out away from the screw D under the action of the spring N
thus bringing the grooved barrel H again into contact with the projection
the nut ; & short turn of the screw D then enables the article to be gripped by
the jaws A and C.
of
At the back of the box E we place a cover P carrying the bearing K' of the
barrel H.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. In a vice the combination with a movable jaw, of a nut such as G and a
grooved or threaded barrel adjustable eccentrically for the purpose specified.
2. In a vice of the kind described the combination of the box or casing such
As E a nut such as G guided therein and a grooved or threaded barrel adjustable
eccentrically for the purpose specified.
3. In a vice of the kind described a spring adjusting device for a barrel
such as H.
4. The combination and arrangement of parts constituting the complete vice
substantially as and for the purpose described and illustrated in the accompanying
drawings.
