COMPLETE SPECIFICATION.
A Measuring Apparatus for Tailors and other Uses.
I, ADOLF FRIEDRICH CARL SCHRODER of 48 Koenigstrasse, Cassel, Germany,
Merchant, 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 a hand measuring apparatus particularly adapted for
use by tailors and cloth merchants etc. or any other purposes to which same may be
applicable and designed to enable lengths of material (such as used by tailors etc.)
to be quickly and accurately measured without yardsticks or meter-sticks.
This new hand-measuring apparatus is illustrated in the accompanying drawing
in which
Fig. 1 is a front elevation partly in section.
Fig. 2 is a side elevation the measure indicating dials being removed.
Fig. 3 is a plan of the centimetre disc, and
Fig. 4 is a similar view of the meter dial.
a (Fig. 1) is a hollow cylinder carrying on its closed right hand front side or face
an upwardly bent piece which latter serves for the reception of three small
toothed wheels e e e and which also has an extension i bent at right angles serving
as a hand or index.
The hollow cylinder a serves for the reception of the middle or forefinger (that
is to say as a handle) and projects for about two-thirds of its length into a second
drum or cylinder b of suitable diameter internally (and externally) which rotates
about cylinder a as an axis when it is moved over the material to be measured.
In order to prevent the apparatus from being moved along without rotating the
solid cylinder the latter is covered at its periphery with a layer of cloth c or
otherwise suitably covered roughened or prepared as a frictional surface.
The lowermost one of the small toothed wheels e mounted in the bent piece f
(Figs. 1 and 2) is fixed to the cylinder 6 (see Fig. 1) so that it shares the rotary
motion of the latter and transmits said motion to the two small toothed wheels e¹
and which are situated above the wheel e and are (advantageously) of the same
size as the latter or of any other suitable size.
The uppermost of these small toothed wheels e engages with the teeth on the
centimetre disc g (Figs. 1 and 3). The latter is capable of rotating about a
vertical axle fixed to the hollow cylinder a under the hand i which also serves as
an upper bearing for the axle h see Fig. 1.
The centimetre disc g (Fig. 3) is provided on its upper face with a circular scale
divided into hundredths (or any other suitable division) and has two recesses in
and n the larger one m of which serves to allow the numerals on the underlying
meter disc k to be seen therethrough whilst the smaller recess n serves for the
reception of a small toothed wheel o (Figs. 1 and 3) which is capable of rotating
about a borizontal axle mounted across n.
Directly under the centimetre disc g (Fig. 1) is the meter disc k capable of
rotation in a horizontal plane about the same axle h but disconnected from the
centimetre disc 9.
The meter disck (Fig. 4) has inside teeth gearing with the small toothed wheel o
of the centimetre disc. The disc k is also marked with a circular scale divided into
fiftieths (or other suitable divisions).
Th
The operation and action of the apparatus are as follows:-
The operator places his middle finger or forefinger into the hollow cylinder a
the cloth to

page_text: to be measured; the solid cylinder 6 is hereby caused to rotate and transmits this
motion by means of the small toothed wheels e e e to the centimetre disc g.
The gearing is proportioned in such a manner that the travel of the periphery of b
will be indicated by the index or markings on g for instance the gearing may be
such that 7 revolutions of the solid cylinder b correspond to one revolution of the
centimetre disc g. Thus if the circumference of the cylinder b = 14.29 centimetres
it describes in 7 revolutions a path = = 7 x 14.29 = 100 centimetres which length
(or any part thereof) can be read off the scale of the centimetre dial g.
At each complete revolution of the latter the small toothed wheel o strikes
against the hand i and is arrested by the same and thus moves the underlying
meter disc along to another number of metres which become visible under
the opening m.
Thus by means of the new hand measuring apparatus herein before described
lengths of materials can be measured in an easy and accurate manner.
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. A hand measuring apparatus for the purposes described-in which a
cylindrical body a is moved along the length to be measured and the number of
revolutions described by the accurately gauged periphery of the cylinder in rolling
over the cloth is transmitted by means of suitable gearing such as e e e in such a
manner as to be capable of being read in a visible manner from off an index or scale
whereby the length measured is indicated substantially in the manner herein before
described and illustrated in the drawings hereunto annexed.
2. In a measuring apparatus for the purposes described-a cylinder such as b
capable of rotation about a second cylinder such as a and which is caused to rotate
by being rolled along the material to be measured in combination and acting
in conjunction with small gear wheels e ele which transmit the rotary motion of
the cylinder b to two superposed indicating discs g and k arranged to rotate on a
common axle fixed on cylinder a in such a manner that after each complete
revolution of the disc g the underlying disc k is moved one division by a small
toothed wheel o until the next following number on k becomes visible under the
opening m of the disc g substantially in the manner and for the purposes
herein before described and represented in the drawings hereunto annexed.
