COMPLETE SPECIFICATION.
A Quick Acting Bench Vice.
I, JAMES RILEY DENISON of the City of Grand Rapids in the County of Kent
and State of Michigan, one of the United States of America, Pattern Maker, 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
description:
:―
My invention relates to quick acting bench vices, and is fully illustrated in the
accompanying drawing, in which
Fig. 1. is a top plan of the end of a bench with my device in position; and
Fig. 2. is a sectional elevation of the same on the line of Fig. 1.
Similar letters of reference refer to similar parts throughout the drawings.
N represents the portion of the bench to which my invention is applied.
JJ is a metallic corner piece having two upwardly proseeling sides J J, of a
proper width to cover the entire thickness of the wooden top of the bench, standing
at right angles longitudinally each wing being of the exact length of the movable
jaw G, of the vice, and designed to form the inner, or permenant jaw of the vice,
and both are supported upon a bed .J' that is securely attached to the under side
of the bench and is provided with a counter-sunk bearing j for the reception of a
corresponding projection on the upper side of the swivel plate or support O, to
form a pivotal center upon which the vice may be turned from the end of the
bench, as indicated by the solid lines, to the side of the bench, as indicated by the
dotted lines in Fig. 1.
O is the swivel plate or support by means of which the outer jaw of the vice is
pivotally attached to the bed J' upon the lower surface of the bench, through the
medium of the pivot screw E, as hereinbefore suggested. The lower surface of
this plate is provided with a series of backwardly inclined teeth O', designed to
engage with the dog B, to sustain the strain of the vice when it is desired to hold
an article firmly between the jaws thereof.
B, is a dog or pall, pivotally supported in the nut block K by heavy lugs a a,
as shown in Fig. 1, so that the teeth P, may be raised or lowered to engage with,
or disengage from the teeth O' on the surface of the swivel bed O, for the purpose
hereinbefore stated. When the vice is closed, the dog may be thrown out of
contact with the teeth by turning the screw D, until the pin or projection A, at
one side near its back end, comes in contact with the body of the dog, back of its
pivotal center, and, throwing the back end thereof, up throws the front end, or
teeth P, down, and out of contact, so that the vice may be opened without turning
the screw, as is necessary with ordinary vices, although this pin, or projection, does
not operate the dog when the jaw of the vice is partially open.
The bench screw D, is operated by means of the handle 1. in the usual
manner.
L, represents the lower portion of the vice, and forms a guide-way for the nut K,
as well as a support for the back end of the screw D as indicated in Fig. 2.
G, is the outer or movable jaw of the vice, and may, if desired, be faced with a
temperary wooden jaw F, and is provided with a bench hook H, that may be
raised or lowered at pleasure, and may, or may not be provided with serrations or
teeth as desired.
A glance at the drawing will show that the movable jaw may be easily pushed
toward the bench as the dog B, will slide back over the teeth O, without
difficulty

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. A bench vice consisting of a laterally swinging jaw G, a metallic frame-work J
having two right angled, perpendicular sides and a bed, a bench screw and swivel
supported by the bed plate of the said frame-work said screw moving with, and
moving the laterally swinging jaw, substantially as specified and shown.
2. A bench vice provided with a swinging jaw, a metallic frame work having
two right angled, perpendicular sides, and a bed adapted to support the swinging
jaw and its adjunctive mechanism, a bench screw and swivel supported upon the
bed of said frame work, and having no projection, or bolt connection, directly with
the bench, said jaw adapted for use at both the side, and the end of the bench,
substantially as described and shown.
3. The combination of a frame having two perpendicular sides at right angles,
and a bed, a frame pivotally connected with said bed and adapted to support the
movable jaw of the vice, and a dog, a ratchet, and a screw for operating said
movable jaw, substantially as described.
4. The combination, in a bench vice, of a metallic frame-work, having per-
pendicular sides at right angles, and a webed bed; with a support pivotally
connected to said bed, and provided with backwardly inclined teeth upon its
lower surface, a movable jaw supported by, and movable with said pivoted frame,
a dog, a screw having a projection for operating said dog, and a nut, substantially
as described and shown.
Dated this 22nd day of June 1883.
