COMPLETE SPECIFICATION.
Improvements in Vises.
We, JOHN L. CARPENTER, Machinist, and WALTER M. HARRIS, Pattern
Maker, both of Auburn, New York, United States of America, 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:
Our invention relates to improvements in vises; and it consists in the novel
features of construction hereinafter fully described and claimed, and illustrated in
the accompanying drawing, in which
Figure 1 is a longitudinal sectional view of the vise.
Figure 2 is a similar view of a portion of the same, showing the nut in a lowered
position.
Figure 3 is a detail view of the nut holding device.
The object of the invention is to provide a quick action vise which may be,
moved either way longitudinally independent of the screw mechanism, and a further
object is to provide an improved means for breaking the screw connection.
A is the base of the vise and B the stationary jaw extended vertically therefrom.
This jaw is recessed in the usual manner and extended therethrough is arm C
carrying at its outer end the movable jaw D. Within the arm C is the
longitudinal screw E which is suitably journalled and carries at its outer end the
operating pin F.
Beneath the screw and adapted to engage therewith is the nut G, semi-circular
and screw threaded at its upper end, and at its lower end provided with the
shank H which depends through recess I in base A. This recess communicates
with the longitudinal recess J which leads to the outer edge of the base, and
movable in recess J is wedge K upon which the shank of the nut rests as shown.
The wedge is constructed with an outwardly extending stem L which is broken
and pivoted together at M, while at its outer end it is screw threaded upon which
is run the nut N. The outer end of the spring bears against the stop J' and serves
to hold the wedge normally in an inwardly extended position beneath the nut.
The nut N may be worked either way as the tension of the spring may require.
When the movable jaw is to be adjusted a considerable distance, and it is desired
to save time which would be required to adjust the same by the screw, the nut G
is lowered by withdrawing wedge K as shown in Figure 2 when the movable
portion of the vise may be positioned as desired. The wedge is held withdrawn by
breaking the joint M in stem L as shown, so as to lodge end M¹ of the stem section
against the outer side of the base, thus preventing the spring from acting. As
soon as the vise has been adjusted the stem is straightened and the wedge returned
beneath the nut G by the spring.
Gaines G of the nut stem support the nut on the base after it has been
disengaged from the screw and the wedge removed.
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 :-
1st. An improved vise comprising a fixed jaw, a movable jaw, a screw for
adjusting the latter, a nut which the screw engages, a wedge beneath the nut for
holding it in said engagement, and a spring for holding the wedge normally in said
position, substantially as shown and described.
2nd. An improved vise comprising a fixed jaw, a movable jaw, a screw for

page_text: adjusting the latter, a nut which the screw engages, a device for holding the nut
in said engagement, a stem extending outward from said device and provided with
a pivoted break between its ends for the purpose stated, and a spring coiled about
the stem, substantially as shown and described.
3rd. An improved visé comprising a fixed jaw, a movable jaw, a screw for
adjusting the latter, a nut which the screw engages, a wedge for holding the nut
in said engagement, a stem projecting from the wedge, a spring coiled about
the stem for the purpose stated, and a means for holding the wedge withdrawn, as
described.
&
4th. In an improved vise, a base constructed with recesses I, and J, a stop J',
fixed jaw, a movable jaw, a screw for adjusting the latter, a nut which the screw
engages, a wedge for holding the nut in said engagement, a stem projecting from
the wedge, a spring coiled about the stem which engages the wedge at one end and
the stop J at its opposite end, and a means for holding the stem and wedge.
withdrawn, substantially as shown and described.
5th. In an improved vise, a base constructed with recesses I, and J, a fixed jaw,
a movable jaw, a screw for adjusting the latter, a nut for engaging the screw, a
wedge for holding the nut in said engagement, a stem extending from said wedge
which is screw threaded at its outer end, a nut adjustable thereon for the purpose
stated, and a spring encircling the stem for holding the wedge normally beneath
the nut, substantially as shown and described.
