the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF PARALLEL, STAPLE,
AND OTHER VICES."

PROVISIONAL SPECIFICATION left by the said John Pattinson at the Office
of the Commissioners of Patents on the 28th April 1879.

MANUFACTURE OF PARALLEL, STAPLE, AND OTHER VICES."
"IMPROVEMENTS IN THE
These improvements relate to the manufacture of parallel, staple, and other
vices.
These improvements consist in making the box in two or in several parts,
instead of in one piece as now ordinarily manufactured.
In carrying into effect this Invention the part of the box which is threaded
or chased to receive the vice screw is made separate from the remaining portion
of the box, and is in the form of a tubular lining; this threaded lining is fastened
into a tube which is provided with an external collar or washer at or about tho
centre of its length, the end of the tube (opposite to that into which the threaded
lining is inserted) is plugged with a hollow or solid plug, having the same form
externally as the corresponding end of an ordinary solid box, or being of other
convenient form, the end of the plug in the tube will extend to the innermost end
of the loose threaded lining, the parts which compose the complete vice box being
secured together in any ordinary manner. As a modification of the above des-
cribed vice box, the solid end and the tube with the collar or washer could be in
one piece and the threaded lining be inserted therein.
These improvements consist secondly, in constructing parallel vices with the
front fixed jaw and bed in one piece, or connected together by bolts, or otherwise,
the jaws being of ordinary form and the bed being made with flanges having
grooves or being recessed, the base of the moveable jaw having projections which
will fit into the grooves or recesses in the flanges of the bed of the fixed jaw, or
CD

page_text: the bed of the fixed jaw may have grooves at each side or one groove at each
side, and the bed of the moveable jaw have flanges over-lapping the sides of the
base of the fixed jaw, so that the sliding jaw will move thereon and be secure
therewith, the moveable jaw being made with projections to correspond with and
fit into the grooves in the bed of the fixed jaw; instead of the grooves being in
the bed of the fixed jaw they may be in the base of the moveable jaw, and corre-
sponding projections be on the bed of the fixed jaw, or any convenient form of
projections and recesses may be formed on and in the bases of the jaws, so that the
base of the sliding jaw will be secure with and slide on the base of the fixed
jaw.

IMPROVEMENTS IN THE
This Invention relates to the manufacture of parallel, staple, and other vices.
This Invention as applied to parallel vices consist in making the front jaw and
bed in one piece or connecting them together by bolts or otherwise, the jaw being
of the ordinary form, and the bed and sliding jaw being of the form of a
dovetail or of other convenient form, which admits of the back jaw sliding
securely on the top of the bed, and this Invention further consists in making
the vice box in several parts, so that that portion liable to wear may be dis-
placed and replaced by a new duplicate wearing part by which the remainder
of the box will be retained in use and saving thereby be effected.
In carrying into effect this part of my Invention the portion of the vice box
which is threaded to receive the vice screw is made in the form of a tubular lining;
this threaded lining is fastened into the tubular vice box in any ordinary manner,
the said box being of the ordinary form externally. The back end of the box is
fitted with a plug which retains the threaded lining in position.
In the arrangement I prefer, the lining is inserted from the back of the box, and
is driven to its place at the front end of the box until it is in contact with an
internal lip or collar formed in the end of the said box; the lining has a projection
which slides in a groove in the box to prevent the lining turning round in its
place; the plug is inserted in the back end of the box to prevent the lining moving
longitudinally. The box lining and plug are or may be taper to ensure a better
fit and to facilitate the withdrawal of the plug and lining. As a modification of
the above described arrangement the box and sliding or back jaw may be in one
piece.
The improved vice box is applicable to staple and other vices. In the accom-
panying Sheet of Drawings I illustrate my improved parallel vice. Fig. 1 is a side
elevation; Fig. 2 is a plan; and Fig. 3 is a back end view of my improved vice;
A is the front jaw and A' the bed on which the back jaw B slides; C is the vice
box; F, the vice screw; and E, the plug inserted in the back end of the vice box C.
Fig. 4 is a sectional view of the vice box, threaded lining D, plug E, collar G,
and pin H, the screw F being shewn in elevation; and Fig. 5 is an external view
of the vice box C, collar G, and screw F. The lining D and box C are taper, and
the lining is inserted in the back end of the box and is driven tightly to the front
end thereof, a pin K fitting into a groove in the box C, preventing the said lining
turning round. The collar G is secured in the front jaw A, and has a pin H which.
projects into a groove J in the vice screw, thus preventing the said scrow moving
longitudinally. Fig. 6 is a cross sectional view of the screw and box as taken
through the dotted lines X, Y.
Having now described and particularly ascertained the nature and object of my
said Invention, and the manner in which the same is or may be performed or
carried into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is,―
The improved parallel vice with the front jaw and bed in one piece (or connected
together) in combination with the improved form of box as hereinbefore specified,

page_text: described, and illustrated in the accompanying Sheet of Drawings, and the
application of the said improved form of vice box to staple and other forms of
vice.
In witness whereof, I, the said John Pattinson, have hereunto set my hand
and seal, this Sixteenth day of August, in the year of our Lord One
thousand eight hundred and seventy nine.
JOHN PATTINSON. (L.S.)
