COMPLETE SPECIFICATION.
Adjustable Spindle-guiding Arrangement for Water-meters.
I, JULIUS KEIM, Manufacturer of Machinery, of Weissenfels, in the Empire
of Germany, 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 object of the present invention is an adjustable spindle-guiding arrange-
ment for water-meters, intended especially for such meters, in which the quantity
of water is registered by means of a disc, that is rotated by the body of water
flowing through, particularly the Thomson water-meter.
It is true that contrivances of the kind have already been constructed, but
they labour under the disadvantages that the cones hitherto made use of have been
fixed either above the disc-casing, or on the upper part thereof. As, however, the
motion of the driving spindle for the registering apparatus is produced precisely
on the spot where the disc-spindle comes in contact with the guiding-cone, the
disc is constantly subjected to an unequal strain, the consequence of which is
that the water-meter is never tightly closed, and thus constantly works
inaccurately.
These disadvantages of the known kinds of construction are obviated by the
present invention in the following manner:-In a second bottom of the disc-
casing a cone furnished with conical bearing surfaces and with screw-thread and
counter-nut acts as adjustable bearing point for the disc-spindle. By means of
this arrangement, the disc can be kept in constant uniform contact with the casing
and the driving parts. Moreover, by reason of the friction produced between the
guide-roller and the guiding-cone, the disc of the water-meter bears a constantly
uniform strain from both sides.
The object of the invention is illustrated in the accompanying drawing, this
drawing showing a section of a so-called Thomson water-meter.
The disc-casing of the water-meter is provided with a second bottom 1, beneath
which a screw thread contrivance furnished with a cone is arranged. The cone-
shaped part 4, which is screwed high enough, rests against the roller 6, placed
at the end of the measuring-disc spindle 5. By raising or lowering the screw-
thread arrangement 3, the position of the measuring disc 2 can be correspondingly
regulated.
The roller 7 on the upper end of the disc-spindle serves as moveable bearing for
the driving spindle 8 belonging to the indicating mechanism. Thus, the register-
ing apparatus is in no way affected by the adjustment of the thread-screw
contrivance 3.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. Disc water-meter with adjustable spindle-guiding arrangement, the dis-
tinguishing feature of which is that by means of a thread-screw contrivance 3,

the disc-casing, the disc-spindle 5 can be adjusted, by means of the guide roller 6,
(which comes in contact with the bearing surfaces 4), in such a manner that a tight
closing of the measuring disc 2 and a uniform strain of the same on all sides are
ensured.
