Improved Parallel Vice.
I, GOTTLOB SILLER, of Esslingen o/Neckar in the Kingdom of Wurtemberg,
German Empire, Merchant, 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 novelty consists in the vice being circularly adjustable in a horizontal
direction on its guideway, whereby one is enabled to operate from the workman's
place upon all sides of a piece of work screwed in the vice, without the work
having to be placed in a different position. A further novelty is the arrangement
of the spindle between the slide-guide and the jaws in such a way that the counter-
pressure upon insertion of a piece of work is doubly increased.
In the accompanying drawings
Fig. 1 shews the circularly adjustable vice in side view,
Fig. 2 shews the raised upper-part and the underpart,
Fig. 3 the guideway with star-wheel,
Fig. 4 is an underside view, and
Fig. 5 an end view,
Fig. 6 a view of the guideway with star-wheel.
On the plate p of the guideway B, fitted with set screw s, is a vertical screw »
applied in round projection r, which screw carries a horizontal star-wheel R, the
screw is formed with a button-like head k. The round projection is for the purpose
not only of receiving the screw, but at the same time of serving as guide to the
base a upon the vice being turned. The vice is formed on its base a (Figs. 1, 2
and 4) with grooves, of which that marked e serves for the reception of the
star-wheel R, and that marked e' for the reception of the button-like head k.
The vice itself consists of the part O, firmly connected with the base a, and of
the moveable part O'.
In the part O is a right angled guide F formed with groove n in which the
slide P of the part O' is arranged to slide.
The spindle S, arranged capable of being turned, in the part O has at its end
the thread g; this spindle takes into the thread of the bore b, and serves for
movement of the part O'.
In order to adjust the vice on the guideway, the star-wheel R is turned to the
right, the vice is thus loosened and can be brought into the desired position in which
it is then secured by means of turning of the star-wheel R to the left, so that the
head k presses against the surface ƒ of the groove e' and the vice is pressed upon
the plate of the guideway.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A. horizontal circular adjustable parallel vice characterized by the guideway (B)
carrying plate (p) which latter has a round projection (x), and receives the vertical
screw (r) with head (k), carrying the horizontal star-wheel (R), as also by the
upper-part provided with grooves (e and e¹), which is secured by means of the star-
wheel (R) fitting into the grooves, and formed with screw (r), and by means of the

page_text: head (k) whilst upon turning of the vice, the base (a) of the latter is guided on
the projection (e), substantially as described and illustrated in the drawing.
Dated this 12th day of December 1893.
