Improved Device for Use in Measuring Cloth and for similar
Measuring Purposes.
I, ADOLF SCHRÖDER of Hedwigstrasse, 5, Cassel, Empire of 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 :-
The present invention relates to a counting device for use in measuring cloth
and for similar measuring purposes.
In the accompanying drawing the device is represented in Fig. 1, in elevation,
in Fig. 2, in section, and in Fig. 3, in perspective.
The new counting devico is fixed at the end of the divisions of the rule which in
this instance is provided with a handle a (Fig. 3).
The device is operated by pressing the thumb against a spring pawl b which
carries a ratchet pawl in the form of a spring blade which engages with the teeth
of a ratchet wheel c. The ratchet wheel c has divisions marked upon it its spindle s
carrying a fixed pointer e.
The casing enclosing the ratchet wheel c contains a spiral spring f secured
at one end to the spindles the other end of this spiral spring forming an
enlargement which is secured to a pin c on the ratchet wheel c.
In using the apparatus when the ratchet wheel c is turned by the pawl d in the
direction of the arrow shown in the drawing in Fig. 2, the spring is compressed a
trigger which can be released when desired preventing the ratchet wheel from
turning
back during the measuring operation. When the divisions have all passed
(i.e. when the wheel has made a complete revolution) the pin e' of the ratchet-
wheel c holding the spring strikes against a stop i on the casing g and prevents
the ratchet wheel c from turning any further.
When the triggor his released by the finger at by lifting the spring pawl h
the ratchet wheel c rotates back to its zero position in consequence of the action of
the spring f
When using this device each time after having measured the cloth one length of
the rule the thumb is pressed against the pawl b. Where the whole length of the
cloth has been measured off by the rule the total length can be read from the
divisions of the ratchet wheel and the apparatus may then be brought back to its
original position by lifting the spring pawl h at h'.
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;-
1. A. counting device for rules for measuring cloth and like purposes consisting
of a counting mechanism secured at the end of the divisions of the rule, which
mechanism after the length of the rule has been measured off, is operated by the
pressure of the finger against a spring pawl substantially as set forth.
2. The construction of the counting device characterised in Claim 1. in which
a ratchet wheel c provided with divisions or indications is mounted upon a fixed
spindles which carries a fixed pointer e, the wheel which is controlled by a spring f

being capable of being returned to its zero position by releasing the pawl h
substantially as described.
