Ain which the object to be operated upon is required to be held in an oblique position while the work is being accomplished, said vises, chucks, etc., for metal workin being usually mounted upon milling, saping, drilling and grinding machines which as a rule themselves areequipped with a base upon which they can be swiveled around a vertical axis to facilitate the adjustment for angular cutting.
This improvement relates particularly to an aum'liary support which is placed between the vise or chuck proper and its ordinary swivel base. The object of this particular construction of auxiliary support is to permit the ready adjustment and rigid locking of the vise at any desired angle, that is, tipped sidewise at the same time as forward or back, with either a horizontal or vertical plane in other object is to give to the vise or chuck to which my auxiliary support is applied' universal motion and rigid locking. in any desired position, within the requirements of either machine or bench work.
Figure 1 is a view in front elevation of a support in accordance with this invention, showing the same mounted in supporting position beneath a vise. Fig. 2 is a view in side elevation of the same. Fig. 3 is a central vertical section of the support taken on line C-,D of Fig. 5. Fig. 4 is a similar view taken at right angles tothe line of section of Fig.. 3, or upon line A-B of Fig. 5, and
Fig. 5 1s a top plan View of the support.
rihe members 8 and 9 constitute the principal elementsof'my'invention and each consists of a cylinder having two plane ends or faces one endv otea'ch being a cross section at right angles toftle cylinder axis and therev fore circularinfform arid thetherend cr face of each cylinder belng a section formed States, re-
by a plane oblique to the axis of the cylinder and therefore elliptical in form. The two cylinders are so joined that the oblique or elliptical faces are in `Contact and as the degreeof Obliquity is preferably the same in each, it follows that in one position the two together form a right cylinder. The member 8 may be rotated in a complete circle upon the member. 9 by means hereafter described.
As shown in Figs. 3, 4, and 5 the upper I member 8 is provided on its top with an annular slot 'or recess 10, which receives the clamping bolts 11, by which the vise proper 2 is secured to member 8, and on the bottom of the member 8 is an annular flange l2 which -iits into the annular recess 13. This recess 13 is on top of the lower member 9 and is for the purpose of receiving said `flange 12 and the clamping bolts 14 by which the upper member 8 1s secured to the lower member 9. The top of the member 3 is also provided with an annular slot 15 to receive the annular flange 19 upon the bottom of 9 and also to accommodate the clamping bolts 16, which serve the purpose of securing the members 8 and v9to the member' 3 after 8 and 9 have been adjusted as a whole around a vertical axis.
As will be seen, the top flange on the upper member 8 is provided with graduations for the purpose of indicating the angularity 0f the vise 2 around a vertical axis, while the lower flange of the upper member 8 is provided with graduations to determine the Obliquity of the top surface Iof the upper member 8 upon which the vise 2 is clamped. The bottom ange of the lower member 9 is also provided with graduations for determining the angularity of the vise in whatever tilted position .it may be, around a vertical axis.
The upper member Sis provided with a hole 17 and the lower member 9 with a hole 18 as seen in Fig. 4f, said holes being for the purpose of receiving handles to facilitate their adjustment.
While the application of my auxiliary support is shown in connection with a milling-machine vise, it is in no way coniined to this type of tool, but can be applied to lathe chucks, drill press chucks, bench vises, lixtures, etc., or to the ordinary bench vise "where compoundy angular positions of the work holders are required,and while l have shown the members 8 and 9 having their adjacent surfaces in a certain degree of obliquity with the axis of the combined members, it is evident that this Obliquity may be changed in angle, andI that the adjacent surfaces of the two members' and 9- may be of any desired degree of oblqi/quity.
Having thus described my invention what I claim as new and wish to secure by Letters Patent is, for the purpose described:
In an auxiliary support, two cylindrical members superposed one upon the other, the upper member having its top face at right angles to the axis of the support and its lower face at an oblique angle to said axis, the lower member having its upper face oblique to match with the oblique face of the upper member and its lower face at right angles to the axis of the support, both of said members provided in their upper faces with an annular inverted T-shaped slot, an annular flange on the lower face of the upper member slidabl received in the slot in the upper face of t eA lower member,J clampingl sitioned bolts positioned through said flange and having their heads slidably received in the slot in the lower member for securing said members inadjusted relation, opposite recesses in the sides of said upper member adjacent the oblique edges thereof, adjusting nutsv upon the free ends of said bolts and poin said recesses, clamping bolts having their head secured in the slot in the upper member adapted for securing the support to the object to be supported, angulari ty and 'Obliquity indicating graduations positioned respectively upon the periphery of `thetop and bottom flange of the upper member, `and angularity indicating graduations upon the bottom of the lower member.

In testimon whereof I aix my signature in presence o two witnesses.
