BARNET HENRY JOSEPH, of the firm of B. H. Joseph & Co of Birmingham in the
county of Warwick "AN IMPROVED GAUGE FOR MEASURING THE CIRCUMFERENCE
OF THE WRIST OR ARM AND FOR OTHER MEASURING PURPOSES
"
This invention relates to the construction of an improved gauge especially
applicable for measuring in a simple and expeditious manner the circumference of
the wrist or arm for sizing bracelets the said gauge being also applicable for other
measuring purposes.
In carrying out my invention I take a band of thin flexible metal and from each
end for a certain distance I cut away half the width of the band on opposite sides
so as to form two tongues whereby, when the band is curved into a circle, the
tongue at one end will correspond with the cut away part on the other end of the
band. To the end of each tongue is fixed a clip the free end of one tongue being
passed through the clip of the other tongue and sliding on the outside of the band.
On the outside of each tongue is fixed a rack and into the teeth of the said racks
gears a toothed pinion the arbor of which turns in a plate fixed to a clip embracing
the tongues; the arbor of the pinion is provided with a thumb piece for turning
the said pinion; the said thumb piece carries a finger or pointer which rotates
over a graduated or divided disc fixed or formed on the before mentioned plate;
around the back of the band is fixed a strip of thin flexible metal arranged to
form a guide for and to keep the tongues against the band.
In a gauge of this construction it will be readily understood that if the herein-
before described thumb piece be turned it will turn with it the toothed pinion,
which pinion gearing with the herein before described racks will move the said
IP C21

page_text: racks and with them the tongues in opposite directions and thereby contract or
expand the band of the gauge according to the direction in which the pinion is
rotated, and if the hereinbefore described disc be graduated or divided to correspond
with the pitch of the teeth in the pinion and racks the divisions of the disc may be
made to correspond with certain sizes or dimensions so that when the gauge has
been adjusted to the size of the arm or wrist the finger or pointer will indicate on
the disc the circumference of the wrist or arm or the size of the bracelet required.
I have described the gauge as adapted for a bracelet sizer but it will be under-
stood that the gauge is equally adapted for taking the circumference of other parts
of the body or of other articles by constructing it of suitable dimensions.
In a inodification of the invention I employ a band of thin spring steel or other
suitable metal in one end of which I form a longitudinal slot. On the other end of
the band is fixed a clip through which the slotted end of the band passes and
slides; the said clip is provided with a set screw which passes through the herein-
before described slot. The slotted end of the band is suitably divided and when
the gauge is passed over the wrist or other part of the body, or the article to be
measured, the gauge can be adjusted thereto and fixed in position by means of the
set screw and the edge of the clip will indicate on the band the dimension or size
required.

BARNET HENRY JOSEPH of the firm of B. H. Joseph and Co of Birmingham, in
the county of Warwick "AN IMPROVED GAUGE FOR MEASURING THE CIRCUM-
FERENCE OF THE WRIST OR ARM, AND FOR OTHER MEASURING PURPOSES
"
This invention relates to the construction of an improved gauge especially
applicable for measuring in a simple and expeditious manner the circumference of
the wrist or arm for sizing bracelets the said gauge being also applicable for other
measuring purposes.
In carrying out my invention I take a band of thin flexible metal and from each
end for a certain distance I cut away half the width of the band on opposite sides
so as to form two tongues whereby, when the band is curved into a circle, the
tongue at one end will correspond with the cut away part on the other end of the
band. To the end of each tongue is fixed a clip the free end of one tongue being
passed through the clip of the other tongue and sliding on the outside of the band.
On the outside of each tongue is fixed a rack and into the teeth of the said racks
gears a toothed pinion the arbor of which turns in a plate fixed to a clip embracing
the tongues; the arbor of the pinion is provided with a thumb piece for turning
the said pinion; the said thumb piece carries a finger or pointer which rotates
over a graduated or divided disc fixed or formed on the before mentioned plate;
around the back of the band is fixed a strip of thin flexible metal arranged to form
a guide for and to keep the tongues against the band.
In a modification of the invention I employ a band of thin spring steel or other
suitable metal in one end of which I form a longitudinal slot. On the other end
of the band is fixed a clip through which the slotted end of the band passes and
slides; the said clip is provided with a set screw which passes through the
hereinbefore described slot.
In order to enable my invention to be fully understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1, is
a front elevation and figure 2, a plan of a bracelet gauge or sizer constructed
according to my invention; figure 3, is a plan shewing the gauge or sizer opened
out to its fullest extent; figure 4, a plan shewing the gauge or sizer contracted to
its smallest size; figures 5, and 6, sections on the lines A, B, and C, D, of figure 2,
respectively; figures 7, to 12, detached views of some of the parts constituting the
gauge or sizer; figures 13, and 14, plan and front elevation of the modified con-
struction of gauge or sizer. All the figures are drawn full size. Similar letters in
all the figures represent similar parts.
In figures 1, to 12, a, is the band of thin flexible metal shewn in detached view
at figure 7, from each end of which as shewn I cut away half the width of the band
so as to form the two tongues b, b¹, so that when the band a, is curved into a circle
the tongues will correspond with the cut away parts of the band; c, c¹, are the
clips on the ends of the tongues b, 61, the free end of one tongue being passed
through the clip of the other tongue and sliding on the outside of the band a;
d, d', are the racks (one of which is shewn in detached view at figure 8) the said
racks being suitably fastened such as by means of rivets one to each of the
tongues b, b¹; e, is the toothed pinion (shown in detached front and side view at
figure 9) the teeth of which gear into the teeth of the racks d, and d¹; f, is the
arbor of the pinion turning in the plate g, fixed to the clip h, embracing the
tongues; i, is the thumb piece on the arbor f, of the pinion e, and by which the
pinion is turned; j, is the finger or pointer which turns with the thumb piece i,
over the graduated disc k, fixed on the plate g, and clip h; l, is the thin strip of
flexible metal (shewn detached in figure 10) fixed around the back of the band a,
so as to forin a guide for and to keep the tongues b, b', against the band a; two

page_text: strengthening pieces m, (figure 11) being placed between the strip 1, and band a;
a somewhat similar strengthening piece n, shewn at figure 12, is placed under each
of the racks d, and d¹.
In a gauge of this construction it will be readily understood that if the berein-
before described thumb piece i, be turned it will turn with it the toothed pinion e,
which pinion e, gearing with the hereinbefore described racks d, d', will move the
said racks and with them the tongues b, b¹, in opposite directions and thereby
contract or expand the band a, of the gauge according to the direction in which the
pinion is rotated and if the herein before described disc k, he graduated or divided
to correspond with the pitch of the teeth in the pinion e, and racks d, d', the
divisions of the disc may be made to correspond with certain sizes or dimensions so
that when the gauge has been adjusted to the size of the arm or wrist the finger
or pointer j, will indicate on the disc the circumference of the wrist or arm or the
size of the bracelet required.
Figure 2, shews the gauge or sizer set so that the finger j, points to N° 5 size;
figure 3, shews the gauge or sizer opened out to its fullest extent as when the
finger or pointer j, points to No. 9, and figure 4, shews the gauge or sizer contracted
to its smallest diameter in which position the finger j, would point to N° 1, on
the disc k.
In figures 13 and 14, a, is the band of thin spring metal; o, is the longitudinal
slot in one end of same; p, is the clip; q, the set screw passing through the
slot o.
The slotted end of the band a, is divided or graduated as shewn in figure 14,
and when the gange is passed over the wrist or other part of the body, the gauge
can be adjusted thereto and fixed in position by means of the set screw q, and the
edge of the clip p, will indicate on the graduated band a, the dimension or size
required.
I have described and shewn in the drawing the gauges as adapted for bracelet
sizers but it will be understood that the gauges are equally adapted for taking the
circumference of other parts of the body or of other articles by constructing the
gauges of suitable dimensions.
Having thus described the nature of my said invention and the best means I am
acquainted with for carrying the same into effect I would have it understood that
what I claim is:-
Firstly. The combination of parts forming the improved gauge for measuring the
circumference of the wrist or arm, and for other measuring purposes arranged and
operating substantially in the manner and for the purposes hereinbefore described
and represented in the accompanying drawing.
Secondly. The modified construction of gauge or sizer hereinbefore described and
illustrated in figures 13, and 14 of the accompanying drawing.
Thirdly. The manufacture and use of the improved gauges for measuring the
circumference of the wrist or arm and for other measuring purposes constructed as
herein before described and represented in the several figures of the accompanying
drawing.
In Witness whereof I the said Barnet Henry Joseph have hereto set my hand
and seal this 12th day of April in the year of our Lord one thousand
eight hundred and eighty three
