on for operating the screw. Attempts to use
15 motor power, have usually failed to bind the jaws
together sui?ciently to hold articles between the
same against the ordinary strains from work
thereon. In cases where the jaws have been su?iciently bound together to hold the articles to be
worked upon, then the resistance against opening
the jaws, has been too great to be overcome by
power means properly applied for clamping the
jaws together.
In the use of a hand lever for operating the
“.5 jaws, it is usual to turn the power screw within
a ?xed nut threaded thereover. In the use of a
motor power it has been usual to aflix the screw
rigidly to the movable jaw and to turn a nut over
the thread of the screw of the travelling jaw.
0 Unless the screw is retarded from easy operation
in the jaw, the screw will revolve with the nut
when motor power is applied, and unless the nut
is restrained when hand power is used, then the
nut turns with the screw. In either case the jaw
is not moved. It is therefore an object of this
invention, to provide for both motor power and

guiding a spindle for rotating the screw nut, and - for drawing the jaw 8 inward. A toothed pinion
also adapted for a swivel connection to the bench, 25 is attached on the top end of the spindle as by
for the rotation of the vise thereon, together a screw h, and the base I of the pinion, is rotat
55 with means for holding the vise in various posi- ably mounted on the top of the leg member.
The spindle 26, is extended below the leg, for
any desired distance and carries pulley 21, on the
end thereof. This pulley is turned in either de
sired direction by a belt 28, driven by any ordi
nary reversible electric motor indicated as 29,
with an operating pulley 30. A resilient member
or spring washer or abutment 3|, is slidably
mounted around the spindle beneath the leg, and
retained in position against the same by ordinary
jamb nuts 32. The nuts 32 are adjusted against
the washer 3| with suflicient pressure to cause
the washer to resiliently bind against the leg and
to retard the spindle and pinion from turning,
su?iciently to prevent the nut I‘! from revolving
15 when the power screw i I, is revolved by the hand
lever 16; ‘but to yet permit the spindle to be ro
tated without undue resistance when the belt is
rotated by the motor for operating the nut H.
In similar manner the resilient washer I 4
mounted around the power screwadjacent to
cheek I4’, is adjustably tightened by'jamb nuts
15, to prevent the screw II from turning when
the power nut is revolved by the motor, but is
so adjusted that the screw may be manually op~
25 erated by the lever it. Thus the operator may
select either method of moving the jaw S, and
may preferably use the motor for rapidly mov
ing the jaw for considerable distances, to close
the jaws, and then use the lever for su?'iciently
30 clamping any article between the jaws for work
thereon. When the jaws are to be opened, they
may be loosened by hand, and then opened by
the motor. A stop pin 35 is provided across the
rear end of the tenon, which prevents the jaw 3,
from being carried outward to disengage the screw
H from the nut I‘! after the pin strikes against
the bar 33. The spring members I4 and 3|, are
portion of the movements of the jaw 8, by pres~
sure on respective end of the lever desired to
rotate thespindle in the desired direction. On
release of the pressure, the springs 45 throw the
lever and. switch into neutral position, and
the spindle is immediately stopped by resist
ance from resilient member 3!.
A bar 33 is seated in the rear edge of the leg
and attached as by screw 34. The top of the
bar is projected up and behind the rear exten— 10
sion 22, of the nut 11, .and serves as a position
bearing therefor. A set screw 35 provides suit~
able tension against the rear portion of the bar
to maintain the nut in position.
In use the vise is mounted upon any suitable
bench or platform, with the leg and spindle ex
tended beneath the same for operative connec
tion with the motor, as described. In practice
it is generally advisable to use the hand lever l6
for turning the screw H, to ?nally tighten the
jaws upon any article to be held between the
same; and when the jaws are to be loosened from
such article, it is generally necessary to use the
hand lever therefor.
After the jaws have been
loosened and it is desired to separate or open
the jaws a considerable space apart, or when it
is desired to bring the same together when widely
separated, then the motor is preferably applied.
Thus the nut is rapidly turned over the screw
and the loose jaw rapidly moved to or from the "
?xed jaw, without loss of time. The resilient
member l4 provides su?‘icient friction to prevent
the screw from turning when the nut is oper
ated by the motor; and the resilient member 3!
provides su?icient friction to prevent the spin~ I,
die 25, the pinion thereon 25, and the said nut
from turning when the screw is operated by the
similar, as shown enlarged in Fig. 4, and are pro
vided with resilient lips a, alternately with

45 sitions, which are frequently required by work—
men for various kinds of work and materials, as
indicated by dotted lines in Fig. 3. Meanwhile
the perpendicular position remains unchanged,
and so continues the spindle in alinement for
'50 operation by the motor in all such various posi
tions of the vise. The ?ange 5, is provided with
anyrsuitable number of holes therein as 37 for
pins 38, which may be dropped down into suit
able registering holes 38 in the bench, to prevent
55 lateral movement of the ?ange.
On the lower
portion of the leg is preferably mounted a hand
wheel nut 49, over inner, and outside threads
4|, and t2, respectively whereby the vise may
be rigidly clamped upon the bench by the tight
60 ening of the wheel nut 40.
In order to revolve the spindle in either de
sired direction for opening or closing the jaw 8,
a double ended leverAS is mounted centrally
over an ordinary double acting electric switch
65 (not shown) in a housing M. Springs 45 beneath
the opposite ends of the lever retain the same
normally level, and the switch neutral. Ordinary
electric wires for the reverse currents, are car
ried from the motor to the switch by a cable iii)‘.
70 This switch and lever 43 may be positioned as
indicated on the floor at any desired distance
from the motor for operation by the feet of
the user, 01' they may be attached above or be
neath the bench for hand control. In either
case, the operator may use the motor for any
