PROVISIONAL SPECIFICATION.
Improvements in Cloth Measuring Machines, applicable also to Looms.
I, SOREN JENSEN, of 167, Valley Street, Providence, Rhode Island, U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
This invention relates to cloth measuring mechines, and more especially to
that part thereof which indicates the length of material which has passed
therethrough. Although my device is applicable to most cloth measuring
machines, yet it is designed principally for use in connection with looms.
The object of the invention is to provide improvements which simplify,
cheapen, and render such devices as that to which this invention pertains more
exact in operation.
Machines to which my invention are applicable comprise rollers between
which the cloth passes, and my improved device is designed to indicate the
number of revolutions of one of said rollers, a certain number of revolutions
indicating any particular measurement, such as yards or fractions thereof.
The measuring roller is longitudinally extended, or in existing machines,
an extension is applied to its end, or mounted to run in contact therewith, a
rubber or like band to cause friction being secured on its outer circumference.
A bracket extends over the extension and carries a horizontal shaft upon which
is a star-wheel, the points of which come into contact with a rib on the roller
extension as it revolves. The shaft also carries a worm which engages a tooth-
wheel behind a dial and carried by a pintle to which a pointer is secured to
indicate the measurements on the dial.
If preferred, an intermediate friction wheel runs in contact with the roller
extension, and is mounted in spring-pressed bearings to keep it in constant fric-
tional contact with the roller-extension. In this construction, the friction wheel
has a projecting pin which rotates the star-wheel one stage at each revolution
of the friction wheel.

COMPLETE SPECIFICATION.
Improvements in Cloth Measuring Machines, applicable also to Looms.
I, SOREN JENSEN, of 167, Valley Street, Providence, Rhode Island, U.S.A.,
Inventor, 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 relates to mechanism for measuring cloth, and is especially

page_text: designed for the purpose of measuring the fabric in a loom as it is woven,
so that the weaver can see at any time, how fast the work is progressing.
Reference being had to the drawings hereunto annexed:-Figure 1 is a front
elevation of my improved measuring device. Fig. 2 is a side view thereof.
Figs. 3 and 4 are enlarged detail views of parts of the mechanism; and Fig. 5
shews its application to a loom or other machine for measuring cloth.
The invention comprises a suitable bracket A adapted for attachment to the
loom or measuring machine frame by bolts, screws or the like. A friction-
wheel B is revolubly secured on a spindle C, projecting from the frame, and has
a stud a projecting from its outer face. The stud is adapted to engage between
two teeth of a star or similar shaped wheel D and move it one stage at each
revolution of wheel B. The wheel D is secured to a shaft J, journalled in
bearings r, and carrying the worm g. The worm meshes with the teeth of a
dial-wheel G revolubly mounted on a screw-stud h attached to the bracket A,
and marked circumferentially with any desired series of figures. The star-
wheel D on each of its projections or teeth is provided with a pin d, and
the friction-wheel B has on its outer face an annular projecting flange which,
adjacent each side of the stud a, is provided with a gap f and each end of the
said flange has a tapering point e. To the bracket A a projecting fixed pointer S
is secured or alternatively a fixed pointer V, shewn in dotted lines, may be
secured to the screw-stud h.
The operation of the device is as follows:-When the roll F is turned to wind
the cloth K between it and the roll H, the friction-wheel B resting on it will
be turned, and at each revolution the stud a on its outer face will engage the
star-wheel D and move it the distance of one tooth. When the star-wheel D has
made a full turn, the worm g will have moved the dial-wheel G one tooth and
one yard or other unit of measurement will be indicated by the pointer. At
each engagement of the stud a with the star-wheel D one of the pins dis
moved into inside engagement with the flange b through the gap f and travels
around therein for one complete revolution thus locking the star-wheel from any
motion other than that derived from the stud a of the friction-wheel B, as shewn
in Figs. 3 and 4.
Any suitable spring may be arranged to press the bracket downwards so that
the friction-wheel bears forcibly upon the roll F, which is preferably fitted with
a rubber, cloth or other suitable band L to create fricion. If preferred a coil-
spring may be placed around the shaft J between the end of the worm G
and one of the bearings r.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is-
The hereindescribed improvements in cloth-measuring machines, said um-
provements comprising the device consisting of a bracket adapted for attach-
ment to a measuring machine or loom-frame, a friction wheel carried by
the bracket and adapted to rotate in contact with a roller or other revoluble part
of the machine or loom, a pin projecting from the friction wheel to engage a
tooth-wheel revolubly carried by the bracket at each revolution of the friction-
wheel, a worm fast to and revoluble with the tooth-wheel, a toothed-dial-wheel
revolubly mounted on the bracket and in mesh with the worm and a fixed
pointer to indicate numerals upon the dial, all substantially as, for the purposes,
and adapted to operate as herein before set forth.
