Improvements in and relating to Measuring and Indicating Devices.
I, RICHARD MEYER of Küstrinerplatz 9, Berlin, in the German Empire, Manu-
facturer, 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 an apparatus for measuring and indicating the lengths
of articles such as strips or laths of wood. The machine or apparatus may be
applied for instance to a wood moulding or similar machine to measure the length
of the wood passing through.
Previous measuring and indicating devices for similar use suffer from the draw-
back that they can only be applied to the upper surface of the material to be
measured and are thus open to the objection that they can only be applied to
smooth strips and not to those with profiled or ornamental upper surfaces.
This objection is removed in a machine or apparatus constructed and arranged
according to this invention as it can be applied to either side or to the top or
bottom of the strip to be measured and is also proof against tampering by the
workmen.
In order that my invention may be more readily understood I have hereto
appended a sheet of drawings reference to which is hereinafter made.
Figure 1 illustrates a plan of the apparatus.
Figure 2 is an elevation of the apparatus fixed to a moulding or similar machine.
Figure 3 shews the cover of the notched or serrated ratchet wheel for engaging
and revolving with the wood, in both back and side elevation.
Figure 4 illustrates the means employed for securing a counterweight to the
apparatus.
Figure 5 represents the pivot bearing of the ratchet serrated wheel or its shaft.
Figure 6 is an illustration of the manner and the means employed for loosening
or tightening the pivot bearing.
The apparatus is carried upon a frame one end of which is bent to form an
angle c. Upon the frame r is secured a casing a containing a serrated or notched
ratchet wheel a small part of the circumference of which protrudes through the
casing a to engage with and be rotated by the strip or lath to be measured. The
wheel is secured upon a shaft s the end of which communicates with and operates
an indicating and recording device of the usual construction. The angle of the
frame is furnished with two slots t t and has connected to it by means of the
bolt a rod or arm ƒ bent and slotted at i and carrying an adjustable counter-
weight g.
The apparatus is secured in any desired position upon the moulding or similar
machine by means of a shaft d upon which the frame r is loosely mounted. This
shaft is secured by means of a nut within a slot formed within a bracket or pro-
jection e of the machine. By the action of the counterweight 9 the measuring
wheel b may be pressed with any desired degree of force against the under side of
the strip or lath.
In order to prevent workmen or others tampering with the machine the casing a
carries a cap a which covers the end of the shaft s. The bearing of the shaft is
formed by the screw which is secured in place by the opposing nuts n k (Figure 5).
These nuts are respectively provided with holes o and m and can only be released
by the special keys or spanners carrying the pins and w.
The cap a is open
at the bottom to allow of the insertion of the spanners or keys.

page_text: 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. The combination with a measuring and indicating device of a pivoted or
swinging frame and an adjustable counterweight all constructed and arranged sub-
stantially as hereinbefore described and as illustrated by the accompanying
drawings.
2. In a measuring and indicating device the combination with the covering cap
of a second cap with a screw pivot for the ratchet wheel all constructed and
arranged as and for the purpose hereinbefore set forth and as illustrated by the
accompanying drawings.
3. A measuring device for use with wood moulding or similar machines con-
structed and arranged and operated substantially as hereinbefore described and as
illustrated by the accompanying drawings.
