PROVISIONAL SPECIFICATION.
A New or Improved Counting Device, Especially Applicable for
Weaving Purposes.
I, MAX KOHL, of Poststrasse 51, Chemnitz, in the Empire of Germany, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is a counting mechanism particularly adapted for
weaving purposes, and characteristic by its device for placing the counting wheels
at zero.
Referring to the accompanying drawing, Figs. 1 and 4 are top views respectively
of the uncovered and covered counting box, Figs. 2 and 3 cross sections shewing the
lever H as put down and turned up respectively.
The main shaft A carries the spur-wheel R, which imparts the motion through the
transmission wheel to the first counting wheel 21. By determining the number of
teeth of the wheel R, it is possible to give the counting work a motion which is in
a certain ratio to the revolution of the shaft, thus allowing, for instance when measuring
yards, this measure to be changed into mètres within the counting work.
The counting wheel z¹ consists of a spur wheel with 20 teeth rigidly connected with
the drum carrying the numerals and a wheel with two laterally projecting clinks or
teeth which gears into the transmission wheel m². The latter, having eight teeth,
is provided between each two teeth with a recess of half a tooth, thus allowing the
two teeth of said wheel to gear therein. The wheel m² gears with the wheel ² and
so on, and the mechanism operates in the known manner.
To allow the counting wheels to be placed at pleasure on zero, the transmission
wheels m¹ m² etc. are secured with their common shaft w to a lever H revolvable
about a shaft F parallel to the shaft w. The rail S, when the lever H is turned up,
enters between the teeth of the transmission wheels and keeps the latter with regard
to their recesses in the relative position required for their reengagement. The
levers H, when put down and engaging the transmission wheels, are secured in
their position, on closing the lid D, by means of projections P connected with the
latter:

A. New 'or Improved Counting Device, Especially Applicable for
Weaving Purposes.
I, MAX KOHL of Poststrasse No. 51, Chemnitz, in the Empire of Germany, 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 the means for counting the number of picks made by a
loom and has for its purpose to provide a mechanism of this class which is at the same
time simple and reliable and constitutes an important assistance in calculating the
wages and determining the weft of the fabric.
The improved device, which is applicable to looms of any description, is illustrated
in the accompanying drawing, in which
Figs. 1 and
box.
are cross sections respectively of the closed and opened counting

counting mechanism.
Fig. 7 is a top view of the latter..
The counting mechanism consists of the transmission gear, the counting wheels,
the adjusting contrivance and the casing. The main shaft A carries the spur wheel R,
which by means of the pinion m¹ transmits motion to the first counting wheel Z.
The latter consists of a spur, wheel with, twenty, teeth rigidly, connected with the
numeral drum and a wheel having but two lateral teeth CO Fig. 4 projecting nozzle-
fashion, therefrom and, gearing,with the next pinion m². This pinion has eight teeth,
each second of which, is laterally cut away for about half, its size, L, Fig. 3 thereby
allowing each alternate tooth of the pinion to gear into the two teeth or nozzle of the
first counting wheel. The pinion m² gears into the wheel Z2 and so on, the mechanism
operating and counting in the known manner.
To allow the counting wheels to be at will jointly. adjusted to zero, that is to say placed
in the starting position, the common shaft of the pinions 'm² m² m³.
is connected
with a lever H, which is revoluble about a shaft F, parallel to the axis of the counting.
wheels. Thereby the pinions m² m² are allowed to be disengaged from the counting
wheels by raising said lever and simultaneously pressed against the rail S, which
enters into the recesses between the teeth of the pinions securing the latter with
regard to their recessed teeth in the position required for re-engaging with the
counting wheels,
To adjust the counting wheels to zero and hold the same in that position until they
are placed in gear with the transmission wheels or pinions by depressing the lever,
a suitable adjusting contrivance may be employed preferably consisting of a pin E,
which is passed through corresponding bores J provided in the counting wheels and
side of the box, and extracted after the proper gearing of the pinions with the counting
wheels is effected.
The two arms H₁ and H2 of lever H, when the counting mechanism is in an
operative condition, rest in corresponding recesses N' and N2, in which they are firmly
held in position when the lid of the box is closed.
Having now: particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
A counting device for weaving and other purposes having an adjusting contrivance
for setting the counting wheels at zero which consists of a revoluble lever H carrying
on a common shaft the pinions or transmission wheels m¹ m² m³.
and normally
held in position by the lid of the box when closed, while when the lid is open, said
lever can be raised, thereby disengaging all pinions simultaneously from the
counting wheels or rail S serving to receive and hold in position the pinions
when disengaged, and an adjusting pin E for holding the counting wheels in their
zero position prior to placing them in gear with the pinions, substantially as set
forth.
