To all whom it may concern l I' Be it known that L'JoHN MAIER, a citizen of the United States and residing at Detroit, in the county of Wayne and State of Michigan, 4have invented a new and Improved Vise, of which the following is aspeciiication.

This invention relates to that form of vise in which a jaw is urged toward or from another jaw by meansof an` actuating screw, and one object of -my invention isl to provide a mounting for a vise of this character so designed that the body of the visemay be shifted laterally or longitudi- 1.5 nally into any desired inclination, and in this connection to provide means for lock- 'ing'the vise body in its adjusted positions.

Another object is to provide means for quickly releasing the vise from its locked position to permit' it to be readjusted.

A further object of the invention is to improve the construction of Vises of this character, and particularly by providing means supporting and guiding the movable jaw in its inward relative movements. Y

Other objects will appear in the course of the following description.

My invention 1s illustrated in the accom' panying drawin s, wherein Figure 1 is a side elevation o this improved vise. Fig.

2 is a section on the vline 2 2 of. Fig. 1.`

Fig. 3 isa horizontal section of the socket ortion of the vise body and a plan of the all portion of the support. Fig. 4 is a n315 perspective of a locking dog. Flg. 5 is a `a base plate which is adapted to be secured g to a bench, table, or other suitable support,

:w designated A,.by means of bolts 7. This 4base plate receives a foot 8 which carries a spherical member- 11 having a central bore 12 whose upper end is substantially conical at 14, and the upperportion ot `this ball jformed with a plurality of concentric .Y 30 which is 11 is formed with a number of radially dis- 55 posed slots 15 which intersect the flaring portion of the bore and which do not extend below the central plane of the'ball. Disposed Within these slots are triangular locking dogs 16 whose inner edges 17 ex- 60 -tend parallel to the portion 14 of the cen tral bore. Disposed within this central bore 12-14 is a locking bolt 18 whoseupper end is formed with a 'conoidal head 19 which fits the tapering portion 14 of the bore, and 65 the shank of the bolt extends down through the table A, and through 'a Wear late 20 bearing agamst the under side of t c table.

Lock nuts 21 are carried on the lower end ofthe shank of the bolt and support a lock.-

'ing plate 22 which has a flange or protuberance 23 at one end and at its other end is `enlarged and formed with an aperture for the trunnion or pivot 24 of a cam 25 having'J a'handle 26. This cam and handle actas 75 a )clamp .and normally bear against the wear plate 20 in the. manner illustrated in Fig. l. When this` handle is turned upward, vthe pressure of the clamp against the. wearplate will be relieved, but when the handle 26 is turned downward, Vthe cam and the lug 234 will bear against the wear plate 20 and draw the bolt 18 downward, thus causing the conical head 19 on this bolt to force thevdogs 16 outward so as toproject these dogs slightly beyond the 11p er surface of the spherical head 11 in t e man- 4ner illustrated in Fig. 2. Preferably, the

upper surfaceof the spherical head is lgrooves 27, and each of the do s 16 is provided with 'a like number o notches 28* which aline with these grooves.

The vise bod 29 is formed with a socket` slightly more than a hemisphere so as to embrace the greater portion of the ball or, spherical 'head 11, as illustrated in Fig. 2, aball and socket joint being formed between the base 6 and the vbody ofthe vise permitting the body being tiltcd in any direction upon the globular As illustrated in Fig.' 6, the body may be tilted 45 from the vertical in any dlrection. The walls of the socket 30 are provided at o posite points withdownwardly and centrallly inclined bores (Fig. 2) wherein are disposed coiled springs -31 bearing outer ends of the bores. -constitute detents which may enter the conagainst balls 32 which are urged outward by the spring, these springs in turn bearing against screw-threaded pilugs 33 in the hese balls 32 centric grooves 27 and latch the body 29 in tilted positions. Theereason for notching the dogs 16 is to permit the detent balls 32 to pass these dogs when the body is rotated u on the globular head. Now when the bo y has been shifted to exactly the position desired, it is them locked in this shifted position by the. lever 26, drawing the bolt 18 downward and thus forcing out the dogs 'into engagement with the inside face of the socket with'such force as to lock the parts together.

The body 29 has a fixed jaw support 34, to which the jaw is connected, a supporting bracket 36 extending forward from the socket 30, and also has a longitudinally extending, rectangular passage 37 extending from front to rear. Slidable and fitting within this passage 37 and on the bracket is a longitudinally extending, hollow jawcarrying shank 38, rectangular in cross section and having a longitudinally extending slot 39 in its under side. This shank 38 -carries at its forward end the upwardly extending jaw support 40, to which is attached the transversely extending jaw 41.

Rotatably supported within this shank 38 vis a screw 42 having screw-threads 43. The extreme rear end of the screw has a nut 44 screwed onto it to prevent the screw from being turned out of the main nut to be described later on. A collar 45 is secured to the screw to pull the shank forward when the screw is turned back. The forward end of the screw 42 has thereon a fiange 47 which bears against an anti-friction bearing, preferably a ball bearing, 46. The knob 48 has a transverse hole through which passes a handle 49. Preferably, this knob 48 is formed with'grooves 50 around the handle opening so that when the-handle is slipped to its full extent through the knob, the balls on the ends of the handle will not pinch the fingers against the knob 48. Disposed within the shank 38 is a nut 51 which has a downwardly lextending portion 52, preferably rectangular in plan, fitting a recess in the lower ortion of the body, preferably centrally above the socket 30.

To center the body of thevise, the following described means are lprovided in addition to the small balls 32 that engage inthe grooves 27 in the head. e This centering device consists of a ball 55 shown in Fig. 2, which is'normally forced into the depression 56 (Figs. 6 and 7) in the body of the vise at the center of the socket 32. This ball is forced upward by a spring 57 in a support 58 that 1s centrally mounted in the upper part 19 of the bolt 18. A spring 59 serves 1,ass,4sa

to force this support 58 a ainst the spherical wall of the socket 30 an serves to restrain the'movements' of the vise body on the ball 11, even when the handle26 has been swung up to release the dogs 16.

To holdthe body on the supporting ball, the lower end of the socket 30 1s threaded and a ring 54, whose bore its the ball below its greatest diameter, is screwed onto this threaded portion, suiiciently tight to hold the body in position, but sufficiently loose to permit freedom of movement at all times. This ring is screwed on before the foot 8 of the ball 11 is inserted into the recess in the base plate 6. v

- It will be seen that avise constructed as described and illustrated is very strong and rigid, and will not easily get out of order, and that particularly it may be adjusted into any desired angle within reasonable limits, and may be readily locked in its angularly adjusted or tilted positions. It.

will be seen that the fact that the ball detents 32 snap'into the groove 27 will indicate the angle to which the vise has been set. At the same time, these ball detents will yield readily so as to permit the yvise to be tilted when strain on the locking bolt has been relieved. After thefvise has been adjusted, the locking bolt may be drawn by `actuating the cam handle 36, thus wedging out the dogs and causing them to bind and 'lock very powerfully against the interior face of the socket wall 30, thus locking the vise in its adjusted position.

In Figs. 9 to 11 inclusive I have shown a vise having a base 6 which receives a foot 8 supporting a ball 61. This ball has radial slots 60 to receive the dogs 62 and a bolt 18 having a conoidal head 19 and nuts 21 at its lower end is adapted to force apart the dogs into engagement with the inner face of the socket 63 through the action of the cam 25 having al pivot 24 mounted in the plate 22. This cam again engages the wear plate 20 `on the lower side of the support A.

The body 64 has a socket 63 on its lower side to receive the ball 61, and a ring 66 is screwed onto this socket to prevent the body from being lifted off the ball. A ball 65 may be forced into the depression 67 in the body to center the body by the spring 57 which is mounted in the support 58. A spring 59 holds the support against the inner wall of the socket.

The top of the body is flat and rectangular and is formed with a groove 68 to receive the nuts 69 on the jaws 70. A bearing 72 is mounted in the groove 68 and receives the central portion ofthe screw 73, having right and left threads that enter the nuts 69 on the jaws. These jaws have depending sides 74 and shoes 75'on the lower ends of these sides to position the jaws on the head.

These dogs 62. are vnot provided with and adapte conoidal head 19 of the bolt 18, and the bod is again centered on the ball by the'smal ball 65 resiliently, pressed into a proper depression by the springs 57 and 59.
