Year: 1866

page_text: LETTERS PATENT to George Perry, of Birmingham, in the County of
Warwick, Engraver and Engine Turner, for the Invention of "IMPROVE-
✓ MENTS IN LOCKETS, BROOCHES, AND OTHER ARTICLES OF JEWELLERY."
PROVISIONAL SPECIFICATION left by the said George Perry at the.
Office of the Commissioners of Patents, with his Petition, on the 12th
November 1866..
I, GEORGE PERRY, of Birmingham, in the County of Warwick, Engraver'
and Engine Turner, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOCKETS, BROOCHES, AND OTHER ARTICLES OF JEWELLERY," to.
be as follows:
My Invention consists of the improvements in lockets, brooches, and other
articles of jewellery herein-after described, by which improvements great
facility is obtained in exhibiting or displaying at pleasure any one of a series
of photographic or other miniatures contained in the locket, brooch, or article-
of jewellery.
My said improvements are also applicable to the exhibition of various
designs, devices, and inscriptions in lockets, brooches, and other articles. of
jewellery, such, for example, as the day of the week, the date or day of the
month, and the name of the month.

page_text: I will describe my Invention in connection with a locket. In making a
locket according to my Invention for exhibiting photographic or other
miniatures I fix the miniatures on a flexible band, the ends of which band are
fixed respectively to two rollers; these rollers work in bearings at opposite
sides of the locket, the band passing under the opening in front of the locket.
In the middle of the locket and between the two rollers is an axis, one end
of which projects through the top of the locket and carries a milled head by
which it may be turned. This axis carries a pinion which gears with pinions
on the ends of the rollers. By turning the milled head motion is given to
the rollers, and the flexible band carrying the miniatures is unwound from
one roller and wound on the other roller until the miniature which it is
wished to display is brought under the opening in the locket. The pinions
on the rollers are not connected rigidly therewith, but turn loosely on the said
rollers; they communicate motion to the said rollers" by means of ratchet
discs fixed on the ends of the rollers... Radial grooves on the faces of the
pinions engage with the ratchet discs when the pinion turns in a direction
proper to wind up the flexible band, but when motion is given in the contrary
direction no motion is communicated from the pinion to the ratchet .disc.
By this arrangement the unwinding from one roller. is effected by. the. tension
of the band being wound on the other roller. Other equivalent means: may.
be employed for causing the middle axis to give motion only to the roller on
which the band is being wound. When the locket is to be provided with
the means of indicating the day of the week, the day of the month, and the
name of the month, I arrange the numerals 1 to 31 on-a band worked in the
manner herein-before described. The names of the months I arrange on an
endless band passing over two rollers; the axis of one of these rollers passes
out at the bottom of the, locket, and has a milled head by which it may be
turned. The days of the week are arranged on another..endless band also
passing over two-rollers, the axis of one of which projects through-the-bottom
of the locket, and has a milled head by which it may be turned. By these
arrangements the locket may be, made to answer the purpose of a date
indicator. The same general arrangement of parts of the locket may also be
used for various other purposes with such changes only in detail as, are
required to fit the locket for the particular purpose for which it is wished to
use it. The arrangements of parts described with reference to a locket are
applicable to, brooches and other articles of jewellery.

NOW KNOW YE, that 1, the said George Perry, do hereby declare the
nature of the 'said Invention; and in what manner the same is to be per-
formed to be particularly described and ascertained in "and by the following
statement thereof, that is to say
184
My Invention consists of the improvements in the lockets, brooches, and other
articles of jewellery herein-after described; by' which improvements great facility
is obtained in exhibiting or displaying at pleasure any one of a series of photo-
graphic or other miniatures contained in the locket, brooch; or article of
jewellery.
My said improvements are also applicable to the exhibition of various
designs, devices, and inscriptions in lockets, brooches, and other articles of
jewellery, such, for example, as the day of the week, the date or day of the
month, and the name of the month.
:
I will describe my Invention in connection with a locket. In making a

page_text: locket according to my Invention for exhibiting photographic or other
miniatures I fix the miniatures on a flexible band, the ends of which band
are fixed respectively to two rollers; these 'rollers work in bearings at opposite
sides of the locket, the band passing under the opening in front of the locket.
In the middle of the locket and between the two rollers is an axis, one ënd
of which projects through the top of the locket and carries a milled; head, by
which it may be turned; this axis carries a pinion, which gears with pinions.
on the ends of the rollers. By turning the milled head motion is given to
the rollers, and the flexible band carrying the miniatures is unwound from
one roller and wound on the other roller until the miniature which it is wished
to display is brought under the opening in the locket. The pinions, on the
rollers are not connected rigidly therewith, but turn loosely on the said rollers;
they communicate motion to the said rollers by means of ratchet discs fixed
on the ends of the rollers. Radial grooves on the faces of the pinions engage
with the ratchet discs, when the pinion turns in a direction proper to wind up
the flexible band, but when motion is given in the contrary direction no
motion is communicated from the pinion to the ratchet disk. By this arrange-
ment the unwinding from one roller is effected by the tension of the band
being wound on the other 'roller. Other equivalent means may be employed
for causing the middle axis to give motion only to the roller on which the
band is being wound. When the locket is to be provided with the means of
indicating the day of the week, the day of the month, and the name of the
month, I arrange the numerals 1 to 31 on a band worked in the manner
herein-before described. The names of the months I arrange on an endless
band passing over two rollers; the axis of one of those rollers pases out at
.the bottom of the locket, and has a milled head by which it may be turned..
The days of the week are arranged on another endless band, also passing over
two rollers, the axis of one of which projects through the bottom of the locket,
and has a milled head, by which it may be turned. By these arrangements
the locket may be made to answer the purpose of a date indicator.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in front elevation with the lid or cover turned back a
.locket for exhibiting, or displaying photographic or other miniatures, designs,
or devices constructed according to my Invention; Figure 2 is a cross section
cof the same, the lid being closed; Figure 3 is a front elevation, and Figure 4
a side elevation of the same. The same letters indicate the same parts in
each Figure.

page_text: is the frame of the locket, having a hinged door or lid b, and an inner
door c provided with an opening d, opposite which a miniature, design, or
devices may be brought and exhibited or displayed. The inner door c may be
snapped into the frame of the locket instead of being jointed thereto as repre-
sented; the door b is fastened by the clasp e. f, g, are two rollers turning in
bearings in the ends of the locket. Around the said rollers is an endless
flexible band h, on which the miniatures, designs, or devices to be displayed
are fixed. When it is required to display in the locket a large number of
miniatures, designs, or devices, instead of the endless band represented the
ends of a flexible band may be fixed respectively to the two roller's f, g;
motion is given to the rollers f, g, by means of the middle axis i, the end
of which projects through the top of the locket, and carries a milled or other
head k by which it may be turned; the said axis i carries a pinion 7, which
gears at either side with pinions m, n, on the ends of the rollers f, g. When
an endless band, as represented in Figures 1 and 2, is employed in the locket
the pinions m, n, are connected directly to the rollers f. 9, and are moved
simultaneously by the middle pinion . When, however, in place of an endless
band a long band, the ends of which are wound upon the rollers f, g, is
employed the pinions m, n, are pot connected rigidly to the rollers f, g, but
turn loosely on the ends of the rollers, the said pinions communicating motion
to the rollers through friction plates p, q, on the said pinions acting against
the roughened collars f, g, on the ends of the rollers. The pinions and friction
plates are pressed towards the collars f, g, by the washers of india-rubber 1, r,
or by coiled or other springs. The friction plates p, q, consist of disks of
metal from which a series of radial spring arms are made, which arms are pressed
against the collars by the washers r, r, or springs, as before explained. The
arms of the said friction plates.p, q, are so arranged that there is less resistance
to the motion of the rollers against which they bear in one direction than in
the other direction. By turning the head k of the axis. i in the direction
proper to give motion to the band h in the direction indicated by the arrow
the spring arms of the friction plate a press upon the collar g² and transmit
motion to the roller g while the spring arms of the friction plate p slide over
the collar without communicating motion to the roller f. The band, the
ends of which are attached to the rollers, is thereby wound upon the roller g,
the unwinding, from the roller f being effected by the tension of the band.
When the head k is turned in a contrary direction to that described motion is
transmitted to the roller f by its pinion and friction plate, and the roller:g is
unacted upon by its pinion and friction plate. By the arrangement described
any one of the miniatures, designs, or devices upon the band coiled upon or

page_text: passing round the rollers f, g, may be brought opposite the opening d in the
inner lid c, and displayed by the raising of the outer lid or cover b.
Instead of the arrangement described for transmitting the motion of the
-middle axis to one roller only the arrangement herein-after described and
represented in Figure 5. may be employed.
Figure.5 represents in back elevation on a large scale, with the side plate
removed, and Figure 6 in edge view, another locket constructed according to
my. Invention to answer the purpose of a date indicator, that is to say; for
indicating the day of the week; the day of the month, and the name of the
month. This locket is divided into three compartments' marked respectively
.a, b, c. In.the.compartment a are: two rollers d; e; upon which the ends of
an elastic or flexible band are respectively wound, the said band having
arranged upon it the numerals 1 to 31. Motion is given to the rollers d, e,
by the pinion f on the middle axis i.gearing. with the pinions g, h, on the said
rollers d; e. The axis is turned by the milled head outside the locket.
The pinions g, h, are not connected rigidly to the rollers d, e, but turn loosely
on the ends of the rollers being pressed towards the rollers by disks or washers
of-india-rubber 1, 1, or by springs, but instead of communicating motion to the
rollers by friction plates, as described and represented in Figures 1, 2, 3, and 4,
the said pinions communicate motion by means of ratchet teeth g, h, on the
.faces of the pinions g, h, engaging with ratchet teeth d³, e³, on the ends of the
: rollers d, e. When the pinion f is turned by its milled head k in a direction
proper to wind the band upon the roller e motion is communicated thereto by
the engaging of the ratchet teeth h³ with the. ratchet teeth e, but no motion
is transmitted to the roller d from which the band is being unwound by the
ratchet teeth g³ of the pinion 9 slipping over the ratchet teeth d' of the roller d,
as will be understood by an examination of Figure 5. By turning the
pinion f in the direction. proper to give motion to the roller d the ratchet
teeth g* of the pinion 9 engage with the ratchet teeth d³ of the roller d and
communicate motion to the said roller while the ratchet teeth h³ of the pinion.h
slip over the ratchet teeth without communicating motion to the roller e.
By this arrangement the unwinding from one roller is effected by the tension
of the band being wound on the other roller. The numeral on the band wound
upon the rollers. d, e, is displayed through an opening in the face of the locket.
In addition to the rollers d, e, other rollers may be employed over which the
flexible band may pass. By means of these additional rollers the plane of that
portion of the.band which is brought to view is not changed by the varying
diameters of the rollers d, e, caused by the winding and unwinding of the
. band.
In the compartment 6 of the locket are two rollers m, n, over which

page_text: an endless band passes, on which band the days of the week are arranged.
The axis of the roller m projects from the bottom of the locket, and is turned
by the milled head m³. In the compartment c are similar rollers p, q, over
which an endless band passes on which the names of the months are arranged.
The axis of the roller q passes through the bottom of the locket, and is turned
by the milled head q. By turning the milled heads m³, q³, the required day
of the month and name of the month on the endless bands passing over the
rollers in the compartments b, c, may be brought opposite and displayed
through openings in the face of the locket. The milled heads m², q³, are
prevented from being accidentally turned by means of a hinged cover 1.
same general arrangements of parts of the lockets described and represented
may also be used for various other purposes with such changes only in detals
as are required to fit the locket for the particular purpose for which it is wished
to use it.
The
The arrangements of parts described and represented with reference to a
locket are applicable to brooches and other articles of jewellery.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented, as the
same may be varied without departing from the nature of my Invention; but
I claim as my Invention the improvements in lockets, brooches, and other
articles of jewellery herein-before described and illustrated in the accompanying
Drawing, that is to say, arranging or combining mechanism substantially as
herein described and illustrated in the accompanying Drawing for exhibiting
or displaying at pleasure any one of a series or any one of two or more series
of photographic or other miniatures or other designs, devices, or inscriptions
contained in the said lockets, brooches, and other articles of jewellery.
In witness whereof, I, the said George Perry, have hereunto set
my hand and seal, this Ninth day of May, in the year of our Lord
Lord One thousand eight hundred and sixty-seven.
