A communication by FRANCIS WILLIAM LORING, of 22, Congress Street, Boston,
in the State of Massachusetts, one of the United States of America, Artist.
1 Alfred GEORGE BROOKES of 55 & 56 Chancery Lane in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention to
be as follows:-
This invention has for its object to construct a three-part hinge adapted for
tripods and analagous uses, or in instances where it is desired to connect three
parts together, and provided for independent movement of each.
In accordance with this invention a pintle is provided, which receives upon it
in any usual manner two leaves, they being freely revoluble on said pintle, and
another pintle is provided which may be connected with the first named pintle
rigidly if desired, and if such connection is desired to be rigid, the pintles may be
formed in a single piece, and the last named pintle is adapted to receive upon it the
third leaf, which is also freely revoluble.
The last named pintle is so arranged with relation to the first named pintle that
the leaves thereon may be turned on an axis at right angles to the axis of the first
named pintle, and also may be turned on the axis of said first named pintle as
desired.
Dated this 11th day of April 1892.

COMPLETE SPECIFICATION.
Improvements in Hinges.
A communication by FRANCIS WILLIAM LORING, of 22, Congress Street, Boston,
in the State of Massachusetts, one of the United States of America, Artist.
I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane, in the County of
London, Chartered Patent Agent 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:-
This invention has for its object to construct a three-part hinge adapted for
tripods and analagous uses, or in instances where it is desired to connect three parts
together, and provide for independent movement of each.
In accordance with this invention a pintle is provided, which receives upon it in
any usual manner two leaves, they being freely revoluble on said pintle, and another
pintle is provided which may be connected with the first-named pintle rigidly if
desired, and if such connection is desired to be rigid, the pintles may be formed
in a single piece, and the last-named pintle is adapted to receive upon it the third
leaf, which is also freely revoluble.
The last named pintle is so arranged with relation to the first-named pintle that
the leaves thereon may be turned on an axis at right angles to the axis of the
first-named pintle, and also may be turned on the axis of said first-named pintle
as desired.
Fig. 1 shows in side elevation a three-part hinge embodying this invention
connected to a tripod, and
Fig. 2, an underside view of the hinge with the parts moved into the same plane.
| Price 8d.|

page_text: The pintle a or post, see dotted lines Fig. 2, is of any suitable length and has
mounted on it two leaves c, d, like unto an ordinary two-leaved hinge.
The pintle b, see dotted lines Fig. 2 is herein shown as a cross-bar formed
integral with the pintle a and arranged at right angles to it, although it is obvious
it may be made as a separate piece connected with it in suitable manner.
The leaf e is arranged on said pintle and adapted to turn freely.
The leaves all being freely revoluble on the pintles, the latter are also unre-
strained, and may be moved independently of the leaves.
In operation it will be seen that the leaf e may be turned on its pintleb on an axis
at right angles to the axis of the pintle a, and furthermore, the said leaf e and
pintle may be turned with the pintle a on the axis with said pintle, thereby giving
to said leaf e movements on two different axes at right angles with relation to each
other, and furthermore, the leaves c, d, may be turned on the axis of the pintle a,
and said leaves with the pintle a upon which they are mounted, may be turned with
the pintle on the axis of said pintle.
I do not desire to limit myself to the precise construction of parts, as it is obvious
that the leaves may be formed in various ways, and so also the pintles, whereby
the results above specified may be accomplished.
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 :-
The three-part hinge herein described, consisting of the pintle a, and leaves c, d,
freely revoluble thereon, and the pintle b, and leaf e, freely revoluble thereon, said
leaf e thereby having movements on different axes, substantially as described.
Dated the 28th day of July 1892.
