' AUTOMATIC QUICK-nomme vrsn.

To all whom t may Q onaern: l

Be itl known Ythat .DANrnL' B.` M oGUIfV ionen, a ctizenof theUnitecl States, ,re-

sidingnt Dik'e, lin the, county .of Hopkins and :State of Texas,

has invented certain new and useful VImprovements in Automatic Quick-Acting Vises, .of which the following is a speciiication, reference beinghad to the nsnompanyins drawings- This invention relates to vises, and the e invention is toprovide a very simple and ,easily ,operated vise, in which the jaws arel automaticallyheld closed upon the work until released.

AY--urther .object is torprovide a vlse j which s-'Vsryqnifck in its action and in which strong press ure ,1nay be secured upon the article being held.

A Ifurther Objectis to improve the details ofconstructionofviseslof this character and to provide a device which 1s -very .simple in construction, whchgmay be very cheaplyfmade and which is thoroughly efficient.

My invention is illnstratel in the accompanyng drawings, Vwherein L* Figure l is a Aside elevation of my improved vise in, applied position;

farther to-"l' locking ,rod is over the lever 21 is upper end of the recess. Pivotally mounted upon the extremity of the arm 21 is a locking rod 27, which is arcuate in form and extends downward from the extremity of the lever 21 and through a slot 28 formed in the standard or body 10. This slot 28 is sufliciently large to permit the locking rod 27 to move freely. The extremity of the turned to form a stop 29.

For the purpose of engaging the locking rod and holding the jaws closed upon the work, I form the locking rod 27 with a plurality of ratchet teeth 3() and provide a transverse slot 31 extending through the member 10 and provide a spring detent composed of a flat spring 32 attached to the side face of the member 10 and angularly bent and extending inward through the slot B1, the resilience of the spring causing the angular end to be urged upward and against the notches or ratchet teeth y30. rIhe angular end 33 extends out through the slot 31 a sufficient distance so that the foot of the operator may be placed upon the angular end of the spring and the detent 83 forced downward to thereby release the locking rod 27 to permit the jaws to open. Preferably I provide a spring 311 attached to the jaw 17 at its base or lower end which, when the lever 21 is brought to a vertical osition or a position contiguous to the jaw 17, will contact with the lever and act to urge it outward as soon as the locking rod 27 has been released. This is necessary inasmuch as the lever, when in a locking position, is practically locked against outward movement by the angular end 22 of the lever being disposed in a horizontal plane or at an inclination to a horizontal plane and beyond its center.

The operation of my invention will bek obvious from what has gone before. When it is desired to grasp an article in the vise, forced downward, closing the jaws upon the work. The locking bar 27 automatically locks the lever in its closedl position. Vhen the work has been done, the operator forces downward the detent 33 releasing thelocking-rod 27 and the device will automatically open by reason of the springs 34C and 26. It will be seen that the device is very readily repaired if it gets out of order, and that a very strong gripping action is secured by reason of the peculiar form of the end of the lever 21 and the peculiar form of the recess 24 within which the roller 23 operates. Furthermore it will be seen that the locking feature does away with the necessity of using the screw in order to force the jaws toward or the device has a much quicker action than an ordinary screw vise and also has a very large range of movement.

simply made, that it may be from each other and that Vhile I have illustrated the preferable 6i form of my invention, it will be understood that many modifications may be made without departing from the spirit of the invention. trated in Fig. 1, is formed with an opening 35 and carried by bolt-cutting blades 36 and thus it will be seen that when the jaws 11 and 17 are forced toward each other, the bolt cutting blade which is mounted upon the jaw 17 will pass the opening 35 and coact with the other bolt-cutting blade to cut pieces of iron inserted through said opening 35. Thus whenever the blacksmith desires to cut a bolt or a small rod he can cut it in his vise.

Having described my invention, what I claim is Y 1. In a vise of the character described, a fixed jaw, xa movable jaw, a lever operatively engaging the movable jaw to shift it toward or from the fixed jaw, an arcuate locking rod pivoted to the extremity of the lever and having ratchet teeth, and a detent engageable with the ratchet teeth to hold the lever in adjusted position, said detent being shiftable out of the way to release said locking rod. I

2. In a vise of the character described, a standard formed at its upper end to provide a fixed jaw, brackets extending outward from the standard, a jaw pivoted at its lower end upon said brackets, ears attached to the standard and extending out upon each side of the movable jaw, a lever having an angular end pivoted between said ears adjacent to its angular extremity, the angular extremity operating against the face of the pivoted jaw to urge the pivoted jaw inward when the lever is shifted downward, an arcuate locking rod pivoted to the extremity of the lever and extending through a slot in the standard and having ratchet teeth, and a spring detent operatively engageable with the teeth of the locking rodl to hold the locking rod in ladjusted positions, said detent projecting out beyond the standard to afford a pedal whereby the detent may be depressed out of engagement with the locking rod.

' 3. Ina vise of the character described, a standard terminating at its upper end in a fixed jaw, a movable jaw operatively pivoted upon the standard, ears attached to the standard and between which the movable jaw moves, a lever having an 'angular relatively short end operating againstv the face of the movable jaw, an arcuate locking rod attached to the lever and passing through a slot in the standard, a detent en-` gageable with the locking rod to holdit in its adjusted positions, a spring urging said Preferably one of the arms 19, as illusy the jaws 11 and 17 are y f' last named spring urging the lever and jaws apart, and a spring mounted upon the base of the movable jaw and adapted to engage with said lever when the same is shifted to a position to close the jaws, said Witnesses: locking rod outward when the detent is released.
