It is tion, will be best understood from the following important that the nut or block 23 be slidable description of the accompanying drawing, which and non-rotatable relative to the chamber, and,"

It is a further object of this invention to profor this purpose, I propose to form the chamber and the nut as shown in section in Fig. 3, although other shapes or constructions may be employed for this purpose.

It will be seen from the construction so far described that rotation of the shaft will effect longitudinal movement of the nut within the chamber, and the movable member is free to move longitudinally within the fixed member by merely pushing or pulling the movable member. It is important in attaining the object contemplated by this invention to provide means for optionally locking the nut against movement relative to the fixed member, such means at the same time being operative to release the nut so that it moves with the movable member and the screw shaft whereby the screw maybe employed to clamp the jaWs or release the movable member so that the jaws can be pulled apart. This is accomplished by means of a dog and ratchet mechanism which will now be described.

Reference numeral 25 indicates a recess formed in the bottom of the nut or block 23 which contains a dog 27 between its downwardly projecting end shoulders 28 and 28. In the form shown, the dog Zl'is loosely mounted in the recess and is normally supported on the bottom portion 29 of the enlarged chamber, which has an inclined surface 25 over which the dog rides. The front edge of the inclined surface 29 defines the rear edge of an opening 30, in the bottom of the chamber, through which the dog is adapted to drop into engagement with teeth 3! in the bottom of the passage H4. The teeth 32 may be cast or otherwise formed directly in the material of the fixed body, but, for the purpose of increasing the strength of the unit and facilitating its repair, I prefer to form the teeth on a separate hardened plate 32 which is secured in a recess formed in the bottom of the passage I4 by means of screws 33 and 332' In operation, the screw shaft I8 is first rotated in one direction by means of the bar 35 in the head 36 to retard the nut to the position shown in Fig. 1 where the dog is shown supported on the bottom of the enlarged passage. The movable member [5 may then be pulled out to any predetermined point to admit the reception of work between the jaw, after which it is pushed back until the jaw l3 engages the work. The screw is then rotated in the opposite direction during which the nut is advanced to the position shown in Fig. 2 where the front of the dog 21 drops into engagement with one of the teeth 3|. Further rotation of the shaft is effective to move the jaw into clamping engagement with the work.

In orderthat the movable member may not be inadvertently pulled entirely out of the fixed member, I provide the bottom of the movable member with a groove 38 which receives the top or inner end of the screw 33 or other suitable removable stop member. Reference numeral 39 indicates a shelf provided on the front of the fixed member to support the front portion of the movable member. Reference numeral 4! indicates a cross pin mounted across the rear of the passage through the fixed member where it 'is received in a notch 42 in the inner member when the vise is closed. This pin prevents the nut being inadvertently screwed off the screw shaft in the event it is provided with a thin or narrow dog.

It was pointed out above that one object of this invention was to provide a novel type of swivel base which is especially adapted for use in connection with a vise of the type contemplated by this invention. This base, generally indicated by numeral l2, comprises a base plate 42, the underside of which is recessed as indicated at 43 and the top of which is provided with a projection 44 which is shaped as the inverted frustum of a cone. Reference numeral 45 indicates a socket member mounted over the projection 44 with its lower annular edge 46 engaging an annular bearing face 4! on the base plate. This socket member, which is in the nature of an inverted cup, is cast with or otherwise 'secured to the fixed body member H of the vise.

positions of angular adjustment upon the base plate, I provide the periphery of the upwardly flared projection 44 with a plurality of recesses or teeth 52. The teeth 52 are adaptedto be engaged by correspondingly shaped teeth or serrations 53 on a wedge block 54 which is mounted in I a recess 55 formed in the periphery of the socket member and has an upstanding screw pin 56 extending through an opening in the top of the socket member. The pin56 is provided with a nut member 51 whereby the wedge block may be drawn up into locking engagement with the teeth on projection 44, and the wedge block is made of a height such that when the nut is loosened the wedge block will drop away from the teeth and permit free rotation of the socket and the vise supported thereon with respect to the base.

Various constructions may be employed in the nut member 51, but for convenience in operation, and to provide a positive lock for the nut, I propose to use a bifurcated construction as indicated at 60 within which a lever member 6| is pivoted. The free end of the lever BI is adapted for reception between upstanding wings 62-452 on the top of the socket member, which serve to lock the screw and wedge after they have been adjusted to clamp the projection 44.

It is to be understood that while I have herein described and illustrated one preferred form of my invention, that the invention is not limited to the precise construction described above, but includes within its scope whatever changes fairly come within the spirit of the appended claims.

I claim as my invention:

1. A vise embodying: a fixed member having a longitudinal housing and a fixed jaw; rack teeth in the bottom of said housing; a movable member slidably mounted in said housing; a jaw on said movable member opposite said fixed jaw, said movable member having a passage therethrough and a chamber at the inner end of said passage; a screw shaft extending throughsaid passage into said chamber; means on said screw shaft for restraining same against longitudinal movement relative to said movable member; a nut member non-rotatably and slidably contained in said chamber in threaded engagement with said screw, said nut having a recess in its bottom forming oppositely disposed shoulders; and a dog contained in said recess adapted to be moved in opposite directions by engagement with said shoulders, said chamber having a bottom opening through which one end of said dog is adapted to drop into engagement with said rack when moved by said nut to aline said dog with said opening, and said chamber having an inclined bottom face adjacent said opening over which said dog is adapted to be raised out of engagement with said rack when said dog is moved in the opposite direction by said nut.

2. A vise embodying: a fixed body having a longitudinal passage therethrough; a jaw on one end of said body; rack teeth in the bottom of said passage; a travelling body slidably mounted in said passage; a jaw on the end of said travelling body opposite said first mentioned jaw; a screw shaft rotatably mounted in said travelling body means holding said screw shaft against longitudinal movement relative to said travelling body; a nut member threaded on said shaft, said nut member being non-rotatably and slidably contained within an enlarged chamber in said travelling body; projections on the bottom of said nut member forming a recess defined by oppositely disposed shoulders; and a dog loosely contained within said recess and adapted to be moved in opposite directions along the bottom of said chamber by engagement of the ends thereof with the shoulders on said nut, said chamber having a bottom opening through Wrn'ch one end of the said dog is adapted to drop'into engagement with said rack teeth when moved by said nut to aline said dog with said opening and said dog having a downwardly projecting tooth adapted to engage the rack, the tooth on said dog having an upwardly inclined rear face adapted to ride over the edge of said opening and raise said tooth out of engagement with said rack when said dog is moved in the opposite direction by said nut.
