the length of pieces of fabric usually termed piece goods, and it is also intended
for unwinding the fabric for measurement and rewinding it again while and when
measured.
In the annexed drawing
Fig. 1 is a front elevation of the machine.
Fig. 2 is a horizontal plan thereof.
Fig. 3 is a vertical side view.
Fig. 4 illustrates the arrangement of the parts for unwinding, measuring and
rewinding and
Figs. 5, 6 and 7 are detail views of the measuring and indicating mechanism on a
larger scale.
The machine comprises a strong framing AAA A, in the upper part of which
are arranged two pairs of clasps or holders B B and B¹ B'. These clasps or
holders are provided with diametrical grooves C C and CC, into which the board
or tablet of wood carrying the roll of fabric, and the similar board on which the
fabric is to be rewound are respectively fitted. In order to secure this board
between the clasps, one of each pair of clasps C and C' is formed on the extremity
of a sliding rod D or D', which can be displaced longitudinally in its supports.
For regulating the pressure the screws E and E' are provided, which bear upon the
ends of the rods D D¹ and have fly-wheels F and F' for handles. The screws E E¹
are maintained in the position given them by the set screws G and G' so that they
cannot move forward or backward after the board is adjusted.
The piece of fabric to be measured is fixed between the rotative clasps C¹ C¹ by
the board on which it is rolled and the fabric then passes over the freely rotary
cylinder H. On the upper face of the fabric to be measured and corresponding with
the upper part of the cylinder H and in connection with the counting or indicating
contrivance described hereinafter (see Figs. 5, 6 and 7) is a rotating cylinder in
contact with the fabric to be measured and turning freely on the latter; this
cylinder or roll is set in motion by the longitudinal displacement of the fabric itself
and its rotary motion is transferred through gearing on the top part of the machine,
finally to the disks QQ', one of which, Q', after each complete revolution causes
the other disk Q to advance through one division of its graduated circumferential
scale.
Previously calculating the circumference of the roll P and the number of teeth
on the bevelled wheel attached thereto, the remainder of the train of gearing can
easily be made so that when one yard or metre of fabric has passed, the disk Q¹ will
have completed one revolution and consequently the disk Q have moved forward
for one division of its scale; the number of revolutions and fractions of revolutions
on the disks are indicated by hands L and L.
Between the clasps B B the board or tablet is fixed, on which the fabric is
rewound. This tablet or board is put in movement by the crank M on the clasp B
which is not provided with longitudinal adjustment; this rotating movement draws

page_text: the piece of fabric and unrolls it from the tablet on the clasps B¹ B' causing it to
pass underneath the counting and indicating device, which exactly indicates the
length which has passed beneath it.
Fig. 4 shows the arrangement of the fabric and that of the indicator, which latter
is carried by a sleeve S on the cross rod R fixed on the standard of the machine.
The indicating device can thus freely oscillate on the rod R and press by its weight
on the fabric or upon the roll H. Suitable guiding rollers H'H' may be used if
desired as shown in Fig. 4.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A new or improved machine capable of simultaneously unwinding, measuring and
rewinding pieces of fabric comprising two pairs of rotary clasps adapted to receive
and hold during revolution the boards on which the fabric is wound and that on
which it is to be wound, and a measuring device intermediate of said pairs of clasps
adapted to be operated by the passage of the fabric and to indicate the total of the
length thereof substantially as set forth.
