PROVISIONAL SPECIFICATION.
An Improved Hinge Joint or Bearing for Pins, Brooches,
0
and the like.
I, BARTON ALLAN BALLOU, of Peck Street, Providence, in the County of
Providence, State of Rhode Island, United States of America, Jeweller, do
hereby declare the nature of this invention to be as follows:-
The bearing for the pins of brooches and the like of this invention consists of
a single metallic strip rolled out to the shape of two small rectangular side blocks
connected together by a thin curved strip. From this shape the strip is bent
round so that the side blocks come together and the base of which is brazed or
soldered to the pin or brooch plate, the thin connecting strip then being uppermost
and bent round to a semicircular form enclosing an eye which forms the bearing
for the pintle on which the brooch pin is mounted after said bearing has been
slotted transversely in the middle of its length. A draw plate is used for forming
the bearing block after the rolled metallic strip of which it is composed has been
bent round.

COMT LEID DI MUIFICATION.
An Improved Hinge Joint or Bearing for Pins, Brooches,
and the like.
I, BARTON ALLAN BALLOU of Peck Street, Providence, State of Rhode
Island, United States of America, Jeweller, 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 :-
In the drawing
Fig. 1 is a cross section of a stock for hinge joints of this invention
Fig. 2 section of the same on line - of Fig. 3.
Fig. 3 a front view of the device of the invention.
Fig. 4 an inverted plan view of a brooch with a pin joint made of the stock and
Fig. 5 a side view of the same.
Figs. 6 and 7 shew a modified form of the device.
A is a metallic strip rolled to the shape of two small rectangular side blocks a
connected together by a thin curved web b. From this shape the strip is bent
round so as to bring the two surfaces c together and is then passed through a draw
plate, the result of which operation is shewn in Fig. 2 the two surfaces d forming
a continuous base and the web bin bending and drawing having formed within it
a circular aperture e. The object thus formed is then grooved transversely for
the reception of the bead of the pin tongue, as shewn in dotted lines in Fig. 3,
and a pintle passed through the aperture e and a like aperture in the bead or
eye of the pin tongue thus completing the hinge and obviating the necessity of
soldering two separate sections of a strip to a pin or brooch in order to form a
complete hinge. B is the plate of a brooch, C the pin tongue, E the pin catch.

page_text: Hinge joints made in the manner described have great strength and rigidity.
Each section has a broad base giving a large soldering surface and a firm
resistance to the leverage caused by the movements of the pin when the latter is
inserted in or withdrawn from a garment. In burnishing, the seam at the close
contact of the surfaces c entirely disappears. In case of greater strength being
required the stock or strip may be rolled to the shape of Fig. 6 where one of the
side blocks has an extension or shoulder o. In this case the stock when bent and
drawn to the form shewn in Fig. 7 gives an elongated base. Instead of soldering
this form of joint by its base d t the plate B the joint may be soldered to said.
plate upon the side fin which case the shoulder would be useful as a fulcrum t
spring the pin into the catch E.
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 :-
1. The stock for hinge joints made in one piece consisting of blocks a having
plane surfaces and of a central web, said stock being bent and drawn so as to form
a hinge joint having a continuous base, an inner seam, and an aperture, for the
purpose specified, substantially as described and shewn.
2. The stock for hinge joints made in one piece having plane ends and bent to
form an aperture and the stock grooved transversely for the reception of the head
of the pin tongue, and the base thereof adapted to be soldered to a plate, for the
purpose specified, substantially as described and shewn.
