THOMAS OYERTON, OF CORPUS CHRISTI, TEXAS.
IMPROVEMENT IN HAND-VISES.
Specification foming part of Letters Patent No. 133,171, dated November 19, 1872.To all whom it may concern:
Be it known that I, THom~As OVERTrot, of
Corpus Christi, in the county of Nueces and
State of Texas, have invented a new and use-
ful Improvement in Combination Hand-Vise,
of which the following is a specification:
The object of this invention is to furnish an
implement or tool for the use of mechanics,
which can not only be used as a hand-vise for
holding small articles, but which can be at-
tached to bits or augers for gaging the depth
of the hole bored, and also countersinking such
hole for screws.
In the accompanying drawing, Figure 1 is
a view of a boring-bit with my combination
vise attached thereto. Fig. 2 is a side view
of the vise detached. Fig. 3 is a cross-section
of Fig. 1, giving an edge view of the vise.
Similar letters of reference indicate corre-
sponding parts.
- A and B represent two jaws joined together
at one end by a pivot-pin, C, so that the jaw
13 can play the same as the loose jaw of an
ordinary vise. This loose jaw has a transverse
groove, D, so that it will fit to and hold a bit,
or to a wire when it is screwed up, as seen in
Fig. 3. E is the vise-screw, by means of which
a bit or other article is griped between the
jaws. F is an adjustable countersinking-cut-
ter, attached, by a screw, G, to the jaw A.
This cutter is slotted for the screw G, and isconfined in a slot in the jaw, so that it keeps
its place when cutting, butis readily adjusted,
by means of the slot therein, to cut more or
less, and may as readily be removed for sharp-
ening or other purposes.
Detached from the bit H the vise is conven-
ient for all the uses to which hand-vises are ap-
plied; and when attached to a boring-bit the
depth of the hole bored may be gaged exactly
and the hole countersunk for a wood-screw or
bolt-head, or left untouched by the cutter, as
may be desired. I is a slot in the screw-head,
for convenience in setting saws.
Having thus described my invention, I claim
as new and desire to secure by Letters Pat-
ent-
1. The improved hand implement herein
described, consisting of the jaws A B, hinged
together, the thumb-screw E, and the counter-
sink cutter F, arranged parallel to the trans-
verse groove D, as shown and described, for
the purpose specified.
2. The cutter F, arranged in a transverse
groove of the jaw A, and provided with a slot,
as specified, whereby lateral movement there-
of is prevented and longitudinal adjustment
provided for, as set forth..
