Application August 18, 1937, Serial No. 159,696 4 Claims. (01. 81-33) This invention relates to vises, and particularly tions on the bench while the motor power may be to vises with a movable jaw, operated both manu- applied in all such various positions of the vise. ally and by motor power. With these and other objects to be hereinafter In the use of bench Vises, much delay is fre- shown, I have illustratively exempli?ed my in 5 quently occasioned by the ordinary slow method vention by the accompanying drawing, of which: 5 of manually revolving a power screw for opening Figure 1 represents a side elevation of the vise and closing the movable jaw. Attempts have been mostly in section. made to operate such screws by motor power, but Figure 2 is an end view reduced in size, partly in such attempts, the alternate use of hand in section, taken on meandering line 2-2 of 10 power has been prevented by the rigid connection Figure 1, showing the power means. 10 between the screw and jaw, which has been necesFigure 3 is a top plan of parts of the vise, taken sary to prevent the screw turning within the jaw on meandering line 3-—3 of Figure 1, partly in when power was applied for turning a nut there- section and reduced in size. 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 Figure Li is a perspective view of a form of spring washer for the spindle and screw, enlarged. 15 Like numerals and characters on the different ?gures represent like parts. Numeral 5, represents the ?xed jaw on a frame 5’ and ?ange 6, which is mounted on any suitable work bench ‘i. 8 represents the loose or travel- , 0 ling jaw, which is supported on a horizontal rec tangular tenon or arm 9, which is slidably dis posed in a slot or mortice in through the frame of the ?xed jaw. An actuating screw H is rotatably mounted ,2 through the base Of the travenihg law and pro trudes through a tubular passageway l2, of the arm, which is open at the bottom. A shoulder abutment l3, on the screw outside the jaw 8 and a resilient abutment or washer l4, around the 30 screw and bearing on cheek M’ of the jaw 3, to move the jaw 8 to 01‘ frOm the‘ ?xed law as the screw is turned by hand lever I6. An elongated DOWEI‘ nut H is threaded Over the Screw i l, and rotatably mounted through a post '8, which is 35 projected up‘ into the passageway and Supported hand power, and to provide retarding means to prevent the nut from turning when the hand power is applied to the screw, and to provide re40 tarding means to prevent the screw from turning on a shoulder IQ of the frame. The turning of nut ll, upon the Screw, 01‘ the turning of the screw within the nut, forces the jaw 8 to or from law 5 respectively. , 40 It is a further object of the invention to provide both motor power means for driving the screw for rapidly opening and closing the loose 45 jaw of the device, and also to provide means for gral With, the post iS a tubular leg 29, Which may be positioned thmllgh any Suitable hole as 2| in the bench, and pivotally maintains the Vise On the bench. The leg is tubular, and provides a '45 when the nut is revolved by motor power. Projected downward from and preferably inte hand operation of the screw for tightening the journal bearing for an operative spindle 26, ro jaws rigidly against an object between the same, tatably mounted th?l‘ethrollg - The nut ll car and for loosening the jaws from such article, and ries a rearexte‘nsioh 22, and a for using the motor power when the jaw has been collar with bevelled gear teeth so so released. A still further object is to provide a edge, and a flat opposite face tubular leg projection ‘beneath the ?xed jaw, for against the rear side of the post Central enlarged 23 on the outer. 24, which bears 50 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 rotat 55 with means for holding the vise in various posi- ably mounted on the top of the leg member. 55' 2 2,114,637 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 hand lever I6. tioned by means of the central eye c; over the spindle or screw respectively. tion, the operator may quickly, and without changing his position before the same, have the 40 40 notches b, and are slidably and rotatably posi The leg 29, through the hole inrthe branch, per mits the vise to be swung in various lateral po~ 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 7 By the use of this vise and its means of opera advantages of slow hand power for severe ten sion, and also have the use of the motor drive for rapid movement of the loose jaw.
