The leg is tubular, and provides a '45 hand operation of the screw for tightening the journal bearing for an operative spindle 26, rojaws rigidly against an object between the same, tatably mou e thfilethrollg e nut ll carand for loosening the jaws from such article, and r es a rearexte and a Central enlarged for using the motor power when the jaw has been collar with bevelled gear teeth 23 on the outer.

so so released. A still further object is to provide a edge, and a flat opposite face 24, which bears 5 tubular leg projection beneath the fixed jaw, for against the rear side of the post l8, for a fulcrum 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 rotatwith means for holding the vise in various posiably mounted on the top of the leg member. 5'

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 desired direction by a belt 28, driven by any ordinary 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, sufiiciently to prevent the nut I! from revolving when the power screw i I, is revolved by the hand lever 16; but to yet permit the spindle to be rotated 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 operated by the lever it. Thus the operator may select either method of moving the jaw S, and may preferably use the motor for rapidly moving the jaw for considerable distances, to close the jaws, and then use the lever for sufi'iciently 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 similar, as shown enlarged in Fig. 4, and are provided with resilient lips a, alternately with notches b, and are slidably and rotatably positioned by means of the central eye c; over the spindle or screw respectively.

The leg 29, through the hole in the branch, permits the vise to be swung in various lateral positions, 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 operation by the motor in all such various positions of the vise. The flange 5, is provided with any suitable number of holes therein as 37 for pins 38, which may be dropped down into suitable registering holes 38 in the bench, to prevent lateral movement of the flange. 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 tightening of the wheel nut 40.

In order to revolve the spindle in either desired direction for opening or closing the jaw 8, a double ended leverAS is mounted centrally over an ordinary double acting electric switch (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 carried from the motor to the switch by a cable ii). 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 beneath the bench for hand control. In either case, the operator may use the motor for any portion of the movements of the jaw 8, by pressure 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 resistance 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 sion 22, of the nut 11, .and serves as a position bearing therefor. A set screw 35 provides suitable 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 extended beneath the same for operative connection with the motor, as described. In practice it is generally advisable to use the hand lever l6 for turning the screw H, to finally 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 fixed jaw, without loss of time. The resilient member l4 provides sufiicient friction to prevent the screw from turning when the nut is operated by the motor; and the resilient member 3! provides sufiicient 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 hand lever I6. 7

By the use of this vise and its means of operation, the operator may quickly, and without changing his position before the same, have the advantages of slow hand power for severe tension, and also have the use of the motor drive for rapid movement of the loose jaw.

Having described my invention I claim as new:

1. A vise for cooperative motor and hand power comprising a fixed jaw on a frame, a loose jaw with a tubular arm slidably mounted through said frame, a power screw rotatably disposed through said loose arm, power nut rotatably mounted through the post, a tubular leg projected downward from the post for pivotally maintaining the vise on a bench and for a guide for a spindle, a driving spindle rotatably mounted through the leg, a collar i around the power nut a pinion affixed to the with gear teeth thereon, top of the spindle with teeth in mesh with the gear for rotating said power nut over said screw for moving said loose jaw, a pulley on the lower end of said spindle and motor power means for driving the pulley in alternate directions for rapidly operating the spindle and loose jaw, and means for reversing the motor, resilient means carried on the screw for restraining the screw from turning when said nut is rotated thereon, and resilient means on the spindle for restraining such spindle and said nut from turning when said screw is rotated in the nut with means for manually turning the screw slowly for clamping and loosening said jaw.

2. A vise for hand and motor power use, comprising, a fixed jaw and a loose jaw, a screw for operating said loose jaw, a power nut rotatably mounted on said screw and adapted to be turned thereon for moving said screw and loose jaw latjaw, a post mounted in the erally, resilient means mounted on said screw to restrain the movement thereof sufliciently for the turning of said nut thereon, a spindle and a gear for rotating said nut rapidly by motor power, resilient means carried on said spindle to restrain the movement of said spindle and nut sufficiently for the turning of the screw within said nut for alternately moving said loose jaw slowly by hand power for accurate adjustment of the jaws together, and for separating the same, with means for separately turning said screw and said nut.

3. A vise with a fixed jaw on a frame and a movable jaw on a tubular arm slidably mounted through said frame, a power screw rotatably connected through said movable jaw and projected through said arm, a power nut rotatably mounted within said arm but independently thereof and in mesh with the screw for rotation thereon, a tubular leg extended downward from said frame for pivotal connection with the bench and to permit the vise to be swung in various directions along with said leg and for journal bearing for a driving spindle mounted therethrough, gear teeth around the power nut, a driving pinion on the top of said spindle with teeth thereon in mesh with said gear, for rotating said nut, a pulley attached to the lower end of said spindle for continuous rotation of the same, while the position of the vise about the pivot may vary, with means for rotating said nut for propelling said movable jaw toward and away from said fixed jaw thereby, and means for reversing the direction of travel of said pulley together with resilient means for locking the screw when the power operated means is being used, and means for locking said nut when said screw is being used. 4.
