It will thus be seen that the lever may be selectively and yieldingly retained in position in operative or inoperative position as desired, so that the operative connection of the vise screw with the vise jaws may be established or broken as desired; 7

From the foregoing, the construction and operation of the invention, together with its many In order to selectively effect the locking or releasing engagement of the half nut from the. vise screw, there is provided a chamber 46 in the bottom portion of the base l2, this chamber intersecting the g-uideway 46. An operating lever is provided consisting, as shown in Figure 7, of a shaft 48 which is journaled in the base l2 between the chamber 46 and a forward'side of the base, this shaft having rigidly but detachably secured to its outer end a handle 52, and to its inner end an arm 50 which extends from the chamber 46 into the guideway 40, the handle.

52 and the arm 50 extending in opposite directions from the axis of the shaft 48.

At one end, the arm 50 is provided with an elongated slot 54, while the free end of the handle '52 is provided with a ball 56. The latter provides a finger-grip portion by means of which the lever may be manipulated. As shown best in Figures 3 and 5, the lower end of the half nut 42 is provided with a slot 58 which receives the end of the lever 50, a pivot pin 60 being disposed through the half nut 42, the slot 58, and the elongated slot 54 in the arm 50. It will thus be seen that upon oscillation of the lever, the half nut 42 will be vertically reciprocated in its guideway 40 and thus moved selectively into and out of operative engagement with the screwthreaded portion 38 of the vise screw.

In order to selectively lock the lever into or out of operative positions, a yieldable locking means is provided as shown in Figures 2 and 6. For this purpose, that surface of the handle 52 which is adjacent to the base I2 is provided with a socket or recess 62, receiving a compres-- sion spring 64 which yieldingly urges a locking ball 66 outwardly of the socket and against the adjacent surface of the base l2. The latter is provided with a pair of shallow recesses 68 and which are adapted to receive a portion of the surface of the ball 66 when the socket 62 is in selected registry with either of the sockets 68 and 10. The sockets 68 and 10 are so placed that they will register with the socket'SZ and the advantages will be readily apparent, and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within'the scope of the appended claim.

Having thus disclosed and described the invention, what is claimed as new is as follows:

A bench vise comprising a base having a fixed jaw, a movable jaw, a vise screw carried by said movable jaw, a half nut slidably mounted in said base for radial movement toward and from said screw and engageable selectively with said vise screw, a lever journaled on said base, an arm on said lever pivotally connected with said half nut for efiecting controlled movement of the latter, said split nut having an open-ended slot extending across one side of the half nut, said arm being received in the open end of said slot, a pivot extending across said slot and through the arm and split nut for connecting said arm to said split nut.
