Improvements in Vices.
We, WILLIAM LOREY, and CHRISTIAN GETZ, both of Philadelphia, and FREDERICK
S. DICKENSHIED of Hosensack, Pennsylvania, all in the United States of America,
Manufacturers 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 :-
Our invention consists of a vice having a movable jaw pivotally attached to a slide,
and provided with a depending leg, a stationery slide with a depending leg, and an
eccentric pivoted to one of said legs and adapted to bear against the other, so as to
aid in clamping the jaws.
It further consists in the combination and arrangement of parts, as herein set
forth.
In the accompanying drawing
Figure 1 represents a side elevation of a vice embodying our invention.
Figure 2 represents a vertical section thereof in line, a Figure 1.
Similar letters of reference indicate corresponding parts in the two figures.
A and B designate the jaws of a vice, the jaw A being fixed to the bench C or
other support, and the jaw B being pivoted to a slide D, which extends freely
through the jaw A and freely over a nut E, which is secured to the base of the jaw A
or to the bench C. Fitted in said.nut E is a screw F, which also passes freely
through the slide D and is swivelled thereto, and furthermore passes freely through
the jaw B, its outer end carrying a crank-wheel or handle G, whereby said screw may
be conveniently and properly operated. Depending from the slide D is a leg or
piece El, which extends parallel with the depending leg or piece J of the jaw Bat
the back of the same. The screw F in the present case is swivelled to the slide D by
means of a neck K, which freely encircles a collar I, on the shank of the screw.
To the bottom of the leg J is pivoted an eccentric M, which is adapted to bear
against the bottom of the leg HL, and is provided, substantially as described and
claimed, with a handle N, for operating purposes.
It will be seen that when the jaws are to be opened the screw F is rotated in
the proper direction, whereby the jaw B separates from the jaw A in a parallel-
motion, it being seen that the slide D and leg H follow said jaw B. When the
jaws are sufficiently opened to admit the article to be held, the eccentric is
operated, whereby the jaw B is forced toward the jaw A, and the article between
them is clamped or held in a powerful manner, it being seen that the slide, and
consequently the jaw A is prevented from shifting, owing to the swivelled con-
nections of the screw with said slide. When the eccentric is operated in the
opposite direction, the jaws are released of their holding action on the article, and
the latter may be withdrawn.
If desired, the screw and nut may be dispensed with. In this case the jaw B
may be pushed in and out by hand, and when it is at about the proper adjust-
ment in relation to the jaw Á the slide may be held by an eccentric N₁, which
is pivoted to the jaw A and tightened against the slide D, as will be seen by the
dotted lines, Figure 1 the legs H J and eccentric M being preserved.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is;-
First. A vice having a stationary jaw, a movable jaw, a slide to which the movable
aw is pivoted, depending legs and an eccentric which is adapted to tighten the jaws
hotam11

page_text: Second. A vice having a stationary jaw, a slide working in said jaw, a movable jaw
pivoted to said slide, a nut secured to said stationary jaw, a screw swivelled to the
slide and freely passing through the movable jaw and working in said nut, the said
slide and movable jaw each having a depending log and means connected to one
of said legs for clamping said jaws, said parts being combined substantially as
described.
Third. In a vice, jaws having parallel motions in opening and closing in combina-
tion with a slide to which the movable jaw is pivoted and an eccentric which is
mounted on said jaw in order to close the same against the other jaw, substantially as
described.
