COMPLETE SPECIFICATION.
Improvements in Parallel Wrought-iron Vices.
I, GEORG HÄNSLER, of 3, Isarthorplatz, Munich, in the German Empire Manu-
facturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The object of this invention is to provide a rotatable parallel wrought-iron
vice, which is so constructed that the screw-spindle which operates the movable
jaw is covered, so that the chips and the like resulting from planing or drilling
cannot enter the thread of same, or the hollow space which has hitherto received
the spindle, whereas formerly the spindle had to be taken out and the vice
tilted over for the purpose of removing the chips and the like filling up those
spaces.
In the accompanying drawing the invention is illustrated—
Figure 1, being a side elevation.
Figure 2, a cross section along the line A-B and
Figure 3, an end view of the vice turned to an angle of 45°.
As will be seen from the figures a rail (c) is employed as guide for the jaw (a)
and support for the jaw (b). This rail may be of any length as preferred
according to the object for which the vice is employed.
The end () of the rail (e) is pivoted by means of pins (c) and (e) in
bearings (h) (h) furnished with slots (g) and firmly connected with the bed-
plate (f); the rail (c) being made firm at any desired angle or position by
tightening the screws (¹) in the bearings (h) and (h¹).
The flange (k) as well as the part of the rib close to the same serve for guiding
the jaw (a). The said jaw () as seen by Figure 1 is movable by means of the
screw-spindle (7) whilst the jaw (6) is not influenced by the same, but is firmly
connected with the rail (c) by means of the screw (m).
The screw spindle (4) is supported at one end in a bearing in the jaw (b) and
at the other end in a bearing formed in a projection on the rail (c). The rotation
of the said spindle is effected by means of the rod (z).
The spindle () is covered by the flange (%) of the rail (c) so that the chips
and the like resulting from planing or drilling cannot reach it.
Pointers may be connected with the pins (e) (el), which pointers, moving over
scales placed on the face of the bearings (h) and (h¹) enable the vice to be
adjusted exactly to any desired angle.
It will be easily perceived that with this arrangement it is no longer necessary
as formerly to stretch the piece of work for the purpose of bringing it into
requisite position for manipulation. Moreover the weight of the vice is reduced
to one half compared with those hitherto manufactured of cast iron and there is
no possibility of breaking.
This vice moreover can be made in any desired length.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1.—A parallel wrought-iron vice distinguished by a rail (c) furnished at the

page_text: end (d) with pins (e) (e¹) the rail being pivoted so as to be capable of being
turned to any desired angle in bearings (h) (h¹) firmly connected with the bed-
plate (f); said rail serving as a support to the jaw (a), which is movable by
means of a suitably seated screw-spindle (!), as well as to the jaw (b) which is
firmly connected with the rail (c); the screw-spindle (1) being covered by the
flange (k) of the rail (c) for the purpose of keeping the chips and the like pro-
duced by drilling and planing away from the screw-spindle (l).
2.In the parallel vice mentioned under Claim 1, the arrangement of slots (g)
in the bearings (h) (h¹) for the purpose of enabling the pins. (e) (e¹) and there-
with the rail (c) itself to be retained in any desired position by means of screws.
Dated the 7th day of September 1899.
