AN AUTOMATIC PIVOT OR BEARING FOR LOOKING GLASSES AND OTHER SIMILARLY PIVOTTED ARTICLES
Year: 1884

We, EDWIN VERITY, and JOSHUA MARLAND VERITY, of Call Lane Leeds,
Ironmongers, and BENJAMIN BANKS of Freehold Street Leeds, Joiner, all in the
County of York, do hereby declare the nature of our said Invention for "AN
AUTOMATIC PIVOT OR BEARING FOR LOOKING GLASSES AND OTHER SIMILARLY
PIVOTTED ARTICLES," to be as follows:-
The object of this Invention is the production of an improved friction or grip
pivot or bearing which,-acting by the weight of the movable or swinging part of
the article to which it is attached, is permanently automatic and satisfactory in
its action, and it may be thus described :-
We first construct the fixed or stationary portion of our Invention, which
consists of an oblong plate, having a "dovetailed," taper piece or wedge on its
face, and countersunk screw-holes, for fixing it, with the larger end of the wedge
downwards, to the standard or "upright" of the looking glass or other article
to which it is applied; and we construct what constitutes the actual pivot or
bearing, in two parts, to fit upon this dovetailed wedge, and also to fit into and
against the movable or "swing" portion of our Invention, which consists of a
flat boss or ring of metal, having a taper or countersunk hole, and with wings or
lugs" outside, for the screw-holes and screws, for fixing it to the frame or side
of the swinging portion of the article to which it is applied; and also to so
receive the before-named double or compound pivot, that the weight of this entire
portion, acting upon the dovetailed-inverted-wedge which "carries" or supports
it, in such a manner as to expand and tighten the pivot, shall give,-automatically
and permanently, the necessary friction or grip for retaining the movable or
"swing" portion, in any required position;-the angle of the wedge and dovetail
being varied according to circumstances, and the weight of the swinging portion
of the article.
"
Although the ready removal and replacing of the latter named portion,-
without the pivot becoming detached,--is an important feature of our Invention,
we sometimes employ a "stop stud" or pin, to prevent it from falling away from
the standards, when the whole is inverted.

downwards, to the standard or "upright" of the looking glass or other article
to which it is applied; and we construct what constitutes the actual "pivot" or
bearing in two parts, to fit upon this dovetailed wedge, and also to fit into and
against the movable or swing" portion of our Invention which consists of a flat
boss or ring, having a taper, countersunk or rebated hole, for the pivot; and with
wings or "lugs" outside, for the,screw holes and screws, for fixing it to the frame
or side of the swinging portion of the article to which it is applied. The before.
described countersunk or rebated hole so fits and grips the double or compound
pivot, that the weight of this entire portion, acting by gravity, upon the dovetailed,
inverted fixed wedge, which "carries' or supports it (in such a manner as to
expand and tighten the pivot) shall give automatically and permanently, the
necessary friction or grip for retaining the movable or swing portion in any
required position; the angle of the wedge and dovetail being varied according to
circumstances and the weight of the swinging portion of the article.
Although the ready removal and replacing of the latter named portion,-
without causing the pivot to become detached, is an important feature of our
Invention, we sometimes employ a "stop stud" or pin to prevent it from falling
away from the standards when the whole is inverted.
In the accompanying illustrations Figure 1 is a face view of the fixed, inverted,
dovetailed wedge; Figure 2 an edge view, and Figure 3 a plan of the same.
Figure 4 is a face view of the compound expanding pivot, and Figure 5 a plan of
the under side. Figure 6 is a face view of the movable or swinging portion,
Figure 7 is the back, Figure 8, an edge view, and Figure 9 a section of the same,
and Figure 10 is the edge or side view of the whole; and in these A is the
dovetailed inverted wedge b the compound expanding pivot, and C the ring into
which this fits and presses, when expanded by the inverted wedge.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The construction and application of an automatic expanding frictional or "grip"
pivot or bearing, wherein the automatic grip or friction is obtained by the weight

the manner, and for the purposes bereinbefore described and set forth,
