lViy invention relates to a new and improved
vise for gripping and firmly holding work of
various kinds, and the principal object of my in
vention is to provide a simple, compact and con
venient vise of the quick acting type which does '
not involve the threaded rod or shaft common to
the conventional forms of vises now in general use. -
A further object oi my invention is to pro
vide a vise o-f the character referred to, having
simple and emcient means for ñrmly clamping
and securing work and which requires turning of
the operating handle or knob only through an arc of approximately 90 degrees.
A further object of my invention is to gener
ally improve upon and simplify the construction
of the existing forms of quick acting bench vises now in general use.
With the foregoing and other objects in View,
my invention consists in certain novel features
of construction and arrangement of parts which
will be hereinafter more fully described and
claimed and illustrated in the accompanying
drawing in which:
Fig. 1 is a side elevational view of the im
proved vise with parts broken away and in
section.
Fig. 2 is a horizontal section taken on the line
.5f-_2 of Fig. 1.
Fig. 3 is an enlarged cross section taken on the
line 3--3 of Fig. 1. .
Fig. ¿i is an enlarged cross section taken on the
line li-ll of Fig. 1. i
5 is a section taken on the line 5-«5 of
Fig. 3. `
Fig. 6 is an enlarged detail view showing the
gripping plates in engagement with the sliding
and rotating rod.
Referring by numerals to the accompanying
drawing which illustrates a preferred embodi
ment of my invention, I@ designates the ñXed jaw
of the vise which may be fixed or swivelled to a
bench E or like support and II designates the
movable jaw. which is formed integral with or
iiXed to a horizontal bar I2 that is arranged for
sliding movement through the lower portion of
said fixed jaw.
A. horizontal rod I3, disposed above and par
allel with bar i2, is arranged for sliding and par
tial rotary movement in the two jaws and the
greater portion of said rod has portions on op
posite sides cut away so as to form ilat faces I4.
Mounted for rotation on rod I3, in a bearing
i5 in jaw ii, is a ring i6 having on its outer end
a pair of inclined cam faces I ’I separated by shoulders such as I3 and formed in the inner end
of said ring is short longitudinally disposed slot
t9 which receives a pin 2l] seated in rod I3.
Interposed between a flange 2l on rod I3 and
the inner end of ring It is an expansive coil spring
22. The inner end of sleeve It bears against a
shoulder Ilia on the movable jaw.
Loosely mounted on the outer end portion of
rod I3, is a short sleeve 23 provided on. its outer
end with a hand wheel 2e and said sleeve being
retained on said rod by av disc 25 and screw 26.
The inner end of sleeve 23 is provided with in
clined cam faces 2l, which oppose cam faces il,
with shoulders 28 opposing shoulders I8.
That portion 0f jaw Ill through which rod lil
passes, is provided with two openings 2!! and Sil
separated by a wall 3|; and mounted to rotate
with and slide upon said rod, within opening Sil,
is a sleeve 32 provided on one end with. a flange
33 and projecting from said flange 90 degrees
apart,lare shoulders 3i. (See‘lï‘ig. 3.)
A stop lug 35 is formed on wall 3l in vertical
alignment with the axis of rod I3, between the
shoulders 3G, thus limiting the rotary motion o said sleeve in either direction. '
A torsional spring 3G surrounding sleeve 32,
with one end‘ connected thereto and the other
end bearing on the bottom of opening Se, biases
rotary movement of said sleeve in one direction.
Loosely mounted on rod I3 within opening 2S
is a series of hard metal plates 3l, the lower edges
of which rest on the bottom of said opening be
tween. lugs 38 and said plates normally occupy
slightly inclined positions as illustrated in Fig. 5.
These discs are `provided with openings 39 for
‘the accommodation of rod t3 and the horizontal
diameters of these openings are slightly greater
than their vertical diameters and thus when rod
I3 is rotated 90 degrees so as to position the ilat
faces lll at top and bottom, the curved faces oi
said rod between said ñat faces, will be out of
contact with the horizontal ends of the openings
39 as shown by dotted lines, Fig. 4.
Plates 3l are normally retained in their in
clined positions by a disc ¿i9 loosely mounted on
a pin M, in the upper portion of opening 29 and
forced against said plates by an expansive coil
spring Ma.
Under normal conditions, rod I3 and jaw Il
carried thereby, are held against movement away
from ñxed jaw til, by the “biting” engagement of
the edges of plate 3T at the lower ends of open
ings 35, with the underside of said rod,
