IMPROVEMENTS IN PARALLEL VICE
Year: 1877

page_text: LETTERS PATENT to Wilson Riley, of Keighley, in the County of York, Machine
Maker, for the Invention of "IMPROVEMENTS IN PARALLEL VICE."
ealed the 17th May 1878, and dated the 21st November 1877.
PROVISIONAL SPECIFICATION left by the said Wilson Riley at the Office
of the Commissioners of Patents on the 21st November 1877.

MENTS IN PARALLEL VICE".
tr IMPROVE-
The object of my Invention is to arrange parallel vice in such a manner that
when the vice lever is held in a certain position the loose jaw will be free, and can
be slided towards or from the fast jaw of the vice the distance required to take in
the material that the workman is operating upon, and when the jaws are in contact
with the material between them the workman can instantly apply pressure to the
jaws and secure the material between them quite firm.
I accomplish my object in the following manner:-1 fix the first jaw casting,
which is arranged with a long flange, to the bench in the ordinary manner. At one
end of this flange, and perpendicular to the same, is the fast jaw. At the under
side of this flange is a projection, in which I form two longitudinal grooves, into
which is fitted the slide of the loose jaw. At one end of this slide, perpendicular
to the same, and parallel to the fast jaw is the loose jaw. Through the loose jaw
casting or slide I place a bar in a longitudinal direction, which is supported by
journals formed at each end of the loose jaw slide. This bar is fitted with a lever
at the end next the loose jaw, and near to the other end of the bar is fitted a
scrolled cam, which, on turning the before-mentioned lever, will actuate a block
having a ratchet formed on one side. The teeth of this ratchet are forced into the
teeth of a longitudinal ratchet, which is attached to the above-named long flange,
and the scrolled cam draws the loose jaw towards the fast jaw, and thus secures the
material between the jaws quite firm.

the said Wilson Riley in the Great Seal Patent Office on the 20th May

WILSON RILEY, of Keighley, in the County of York, Machine Maker. "IMPROVE
MENTS IN PARALLEL VICE."
The object of my Invention is to arrange parallel vice in such a manner that
when the vice lever is held in a certain position the loose jaw of the vice will be
free, and can be slided towards or from the fast jaw of the vice the distance required
to take in between the jaws the material that the workman is operating upon, and
when the jaws are in contact with the material between them the workinan can
instantly apply pressure to the jaws, and secure the material therein quite firm.
I accomplish my object in the following manner :-I fix the long flange of the
fast jaw casting to the bench in the ordinary manner. At one end of this flange,
and perpendicular to the same, is the fast jaw, and at the under side of the said
long flange are projections which form the groove, into which is fitted the slide of
the loose jaw casting. Through this loose jaw casting I place in a longitudinal
direction a bar, which is supported by journals formed at each end of the loose jaw
slide. This bar is fitted with a lever at the end next the loose jaw, and near to the
other end is fitted a scrolled cam. By actuating the before-mentioned lever the
scrolled cam will raise a block having a ratchet formed on one side, and the teeth of
this block are forced into the teeth of a longitudinal ratchet that is fixed to the
under side of the before-named long flange, and by further actuating the lever the
scrolled cam will draw the loose jaw towards the fast jaw, and thus secure the
material between the jaws quite firm.
In order that my Invention may be more clearly understood, and how the same
is carried into effect, I will proceed, aided by the accompanying Drawings, more
fully to describe the same.
Figure 1 represents the front elevation of my improved vice; Figure 2 is a plan
of the same.
Figure 3 is a front elevation of the fast jaw.
Figure 4 is a plan of the bottom side of the long flange of the fast jaw casting.
Figure 5 is a longitudinal section through the centre of my improved vice.
Figure 6 is a transverse section through line a, b, in Figure 2.
And Figure 7 is a view of the scrolled cam.
In all the Figures similar letters represent similar parts.
The letter A represents the fast jaw of my improved vice, which is cast to the
slide B. At the under side of the long flange C, forming part of fast jaw casting,
are two projections D, into which is fitted the loose jaw slide B. At the top side of
the before-named groove is a ratchet E, which may be cast to the fast jaw casting,
or otherwise secured thereon. Through the loose jaw casting B I place a bar or
vice spindle F, which is carried by journals formed in each end of the casting B.
At one end of this spindle, next the loose jaw A, I fix a lever G. I also fix near
to the other end of the said spindle a scrolled cam H. On the top of this scrolled
cam, and fitted between the projections J, rests a block L, the top side of which is
formed with a number of ratchet teeth, which correspond in pitch and form to the
teeth in ratchet E. When the lever G is held in a certain position the loose jaw is
at liberty to slide to or from the fast jaw K; and when material is put between the
fast and loose jaws, and the loose jaw slided so as to bring the jaws in contact with
the material, the same is secured by actuating the lever G, which will cause the
scrolled cam H to raise the block L until the ratchet teeth in the same fit into the
ratchet teeth E. The centre line of the scrolled cam H is at an angle with the axis
of the spindle F, and thus the circumference of the cam keeps the teeth of the
block Limbedded in the teeth of the ratchet E, and at the same time the side of
the cam presses against the groove formed in the block L, and draws the loose jaw
towards the fast jaw, and secures the material between the jaws quite firm,

page_text: Having thus described my said Invention, and the manner in which the same is
or may be performed, I have to state that I do not restrict myself to the precise
details herein described and delineated, but that what I believe to be novel and
original, and claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the application of a scrolled cam secured to the vice spindle
which acts upon a block and ratchet, and secures the material between the jaws of
the vice, substantially in the manner herein-before described, and delineated in the
accompanying Drawings.
In witness whereof, I, the said Wilson Riley, have hereunto set my hand
and seal, this Sixteenth day of May, in the year of our Lord One thousand
eight hundred and seventy-eight.
Signed and sealed in the
presence of
