vIsE AND MOUNT THEREFOR.

Application filed ma 19, 1927 Serial No. 192,690.

This invention relates to new and useful improvements in Vises and aims'to provide a highly novel, simple and efficiently operating vise together with a particular construction of a mountlng means' so as to facilitate the rigid. anchoringv of the vise in any desired position with respect to the work table or other support.

In carrying out my invention there is provided means between a generally conventional vise constructionand an attaching unit that will enable the vise to be easily and quickly swung from a horizontal to a vertical position and wherein the vise may be arranged at any desired point within a circle while in either the vertical or horizontal position. Furthermore such means will negative any liability of the movement of the vise after the same has been properly anchored in the desired position.

-In'the drawings wherein like numerals indicate like parts throughout the several views: A

Figure 1' is a viewpartially in front end elevation and vertical cross section of the vise and mount when the device is arranged in horizontal position. v

Figure 2 is a detailsection through the vise and mount, the mount being supported in horizontal position.

Figure 3 is a section through the mounting mechanism and disclosing the vise structure in side'elevation and rigidly anchored to a work table or bench in vertical position.

Figure 4 is a horizontal section taken substantially on the line 4:4of Figure 2 and looking downwardly in the direction of the arrows for'more clearly disclosing the connecting means between the base of the mount structure and the vertically. adjustable pin slidable therethrough and to the upper end of which is pivotally attached the vise structure. I

' Figure 5 is a vertical horizontal section taken substantially upon the broken line 5-5 with a circular opening a. Arranged'upon this bench or table directly over-the opening a is a base unit 5 of hollow cylindrical form having lateral ears 6 at e its lower end through which are openings for facilitating the anchoring of the base unit to the bench or table by bolts or other fastening means 7 The interior of this cylindrical or base unit 5 registers with the opening a in the bench or table and mounted for loose vertical sliding movement and rotation therein is a hollow cylindrical viseattaching post 8, the upper end of which is solid and provided with a vertical bifurcation 9, the branches of which are formedwith registering openings 10- 10. As more clearly disclosed in Figure 6 the outer surface of one branch of said bifurcation 9 is of plano formation so as to be spaced inwardly from the surface of the post to provide a space for a nut within the post surface as hereinafter *more fully de scribed.

For facilitating the rigid sec'uringof the post 8 within the cylindrical base unit 5 after thesame has been raised or lowered and disposition within this socket 11 is a clamp ing sleeve 13 formed longitudinally witha bore within which is mounted anelongated screw 14, the inner threaded end of which is adapted for threaded" engagement within the threaded socket 12 for wedging the inner endof the sleeve 13 against the post 8, said 7 v sleeve at the pointcof engagement with the post being slightly rounded to conform with the curvature of said post. i

The vise structure per se consistsof an open ended cylindrical. bushingholder 15 formed at its surface and intermediate its I ends with an outwardly projecting tongue 16 the end surface thereof being rounded as clearly indicated in Figures 2 and 3; This tongue is arranged within the bifurcated end 9 of the post'8 and is pivoted to the branches thereof by bolt .17 passing through the openings 10-i10 in the bifurcation branches and within an opening in said tongue. This bolt 17 is of the headed and threaded character and is arranged through the end of the post 8111 such a manner that the head thereof will engage the branch of bifurcation havin the Diane surface so that said head will be entirely Within tne confines of the ost to Jermit the u oer end of P 1 Pi the same to be moved downwardly into the base unit 5 together with said holder tonguethe upper end thereof and there maintained by reason of a locking means between the base unit and said post.

By releasing the locking means, the post may be raised after which the bushing holder 15 may be swung over at right angles to the position indicated in Figure 8 and rested vertically upon the upper end of the has unit and there maintained by forcing the post 8 downwardly within the base unit '5 to the limit of its movement and then-locking.

said post to the base unit. Furthermore by reason of the connection between the base unit and post, said post may be rotated to any desired point within the unit so'asto position thevisestructure at any desired point within a horizontal or vertical. circle.

Mounted for longitudinal sliding movement and turning movement within the cylindrical bushingholder 15 is a bushing 18 formed at its outer end and at one side of the bore extending tl'ieret hrou'gh' with a conventional vise jaw 19, For maintaining the jaw bushing 18 at a predetermined adjusted position within the cylindrical bushing holder 15 said bushing holder 15 is formed at its surface with a tangentially extending socket 20 that opens at the surface of said bushing, see Figure 5. For arrangement within this socket 20- is a loeking'sleeve 21 having a bore therethrough'for receiving a headed andthread'edbolt 22, the inner threaded end of which is adapted for threaded engagement within a threaded socket 23 at the inner end of the sleeve'socket 20. 0bviously by turning'this bolt in one direction said sleeve 20 will beiorced into engagement with the bushing 18 for preventing movement of thesame within the holder l5. Furthermore the point 01": engagement of the sleeve with the bushing 18 is rounded to conform to the exterior configuration of said bushing, again see Figure 5. i

The vise structure further consists of a jaw 24 complementary to thejaw 19 and upon the inner face of which is formed a horizontal elongated hollow bar 25, the interior-oi which registers with an opening at thelower end 01" the jaw 24; as clearly ind-icatedin Figure 2. Mounted within thishollow bar 25 and through" the opening in the jaw 24 is an elongated solid bar 26, the outer end of which projects through the jaw 2d and is formed directly adjacent the with a circular flange 27 complementary to which is a stop finger 28 attached to the aw to prevent the outward movement of the bar through said jaw and within said hollow bar 25. The extreme outer end oi. this bar 25 is provided with a: head 29.-th1=o.ughwhich is arranged the-usual operating cross handle 80.

The inner end of the bar 26. is formed with:

a worm '81 while beneath this wormed area slotted as at 32. Securely'arranged within a5 slot 33 formed within the bore otthejaw bushing 18 and at the end opposite the jaw 19' is a worm nut 34 through which the wormed area of the: bar 26 is threaded,see Figure 2, obviously a rotation of the handle 30 will cause the rotation ofthe jaw actuat: ing bar 26 tocause the inward orr outward movement of the jaw 24k with respect to the stationary jaw 19a v r a It will thus be seen thatI have-provided a highly novel, simple, and efliciently opera-t7 ing vise and mounting structure thereforthat is well adapted for all the purposes. heretofore designated, eventhough I have herein shown and described the invention as -conisisting of certain detail structural elements it is nevertheless to cc-understood that some departures may be had theref romwithout affecting the spiritandscope of the append ed claims.

Having thus described the Iclaim as new'isz j I r 1. In combination with 'a' viseincludinga stationary and a movable jaw, said stationary jaw being-formed? with a bushing an 'anged within a bushing holder, saidbushing holder being i provided intermediate 7 its ends with a lateral tongue, a hollow base member, a post movable freely Within the base, a pivotal connection between one end of the post and the tongue of said bushing holder, said connection permitting the engagement of the tongue within the holder, said hollow base member being formed with a tangential invention, what opening communicating-with the bore there of, a member movable within said opening for engagement with the post for fixing or securing the same at a predetermined posi' tion within the base, and a threaded member projecting through Said member threadable into the base for moving said member 'into'engagement with" the post. i

I 2. Incombination with a vise ihclud-ing a stationary and a movable jaw, said stationary jaw being formed with a bushing and arranged within a bushing holder, a tongue pro j'ecting laterally fromthe side'of said bush ing holder, a tubular'ba'se' member, a cyli1i'-' drical post verti callyslidable within said-bas member, a pivotal connection between one end of the post and the tongue of said bushing holder, said hollow base member being formed with a tangential opening communieating with the borethereof, a'member-movable Within said opening for engagement with the post for fixing or securing the same at a predetermined position withinthe base, and a threaded member projecting through said member and threadable into the base for moving said member into engagement with the post.

3. In combination with a vise including a stationary and a movable jaw, said stationary being provided with a bushing and ar ranged within a bushing holder, a tongue pro eating laterally from said bushing holder,
