A Counting Device for Use with Power Looms or other purposes.
I, ROBERT LOUIS SCHOPPER of 27 Arndtstrasse, Leipzig, in the Empire of
Germany, Mechanic, 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 device for counting the number of picks in
power looms and said device has for its object to give the number of the throws
of the shuttle by recording the number of the revolutions of the picking eccentric
shaft.
The pick counting device can be arranged on the framing of the loom in such
a manner as to exclude any tampering with the same by the weaver.
In the accompanying drawings:-
-
Fig. 1 is a section on the line a-b of Fig. 2.
Fig. 2 is a plan of the pick counting device the cover being removed, and
Fig. 3 is a plan with the cover closed.
On the bottom of the case A are arranged two bars B B in which are carried
a number (five in the construction shown) of shafts C parallel to one another. On
these shafts C are fixed the small number-wheels D on the periphery of which
are marked the series of numerals 1, 2, 3, etc.
Each small number-wheel D is furnished with ten pins E which are arranged
on D at equal intervals from one another and parallel to the shafts C (Figs. 1.
and 2).
On all the shafts C (except the last) and at right angles to the same are fixed
pins F which are of such a length that during one revolution of the shaft carrying
the same they engage once between two pins E of an adjacent shaft (in the present
case the shaft located on their left hand side) and cause the latter to revolve
through a distance equal to the distance between two numerals on the periphery
of D.
From this it will be readily understood that each shaft C must make ten
revolutions in order to cause its adjacent (on the left hand in the drawing) shaft
to make one revolution.
In order that the small number-wheels shall remain in any position of revolution
into which they may be moved and that they shall not be rotated any further by
reason for instance of shocks communicated by the shuttle movement etc. etc. to
the loom there are fixed on the bottom of the Casing A springs G (Fig. 1) which
bear against the pins E and allow the small number-wheels to revolve only when
such revolving motion is produced by positive gearing that is by the forcible action
of arms F.
The revolutions of the picking eccentric shaft are transmitted to this counting
device by means of the shafts H and L which are geared by means of bevel
wheels K. J.
H is similarly to the shafts C carried in the bearers B and like the said shafts C
is provided with a pin F. This pin F' on the completion of one revolution
engages with the pins E of the adjacent number-wheel and causes the latter to
revolve to an extent equal to the distance between two numerals.
K and J are geared together in a definite ratio so that H makes one revolution
for a determined number (10 in the case illustrated) of revolutions of the shaft I
and the periphery of the small number-wheel situated nearest to the shaft H is
caused to revolve to the extent of one numeral. But the periphery of this small
number-wheel is not provided like all the rest with the single numerals to 0 but
is marked with the series of numbers 10, 20, 30 to 90 and 00 so that therefore only

page_text: every tenth pick causes this number-wheel which is nearest the driving gear to
revolve.
On the shaft L is mounted a collar N which is slipped over a corresponding
square part of the picking eccentric shaft of a loom and thus serves to drive this
counting device or same may be connected up or driven in any other suitable
manner either in or on a loom or any other equivalent or suitable purposes.
In one corner of the casing A is a pin O which is carried and arranged to
move partly in the bottom of the casing and partly in the lug or bearing P and
which is pressed upwards by the action of a spring R that bears at one end against
a transverse pin Q and at the other end against the interior of the bottom of
the casing A. When the cover of the casing is closed the bolt O projects from
the casing and enters a corresponding opening in the framing of the loom in such
a manner that the entire device can only be removed thence (for the purpose of
adjustment etc. when necessary) when the cover of the casing has been raised to a
certain extent so as to allow the pin O to pass out of the recess in the framing of
the loom.
.
By this means the weaver is prevented from concealing any faults he may have
made by altering the counting device or by tampering with the number-wheels.
The cover of the casing is provided with apertures corresponding with the
number of the said number-wheels through which only that number on each of the
number-wheels can be seen at any one time that happens to be in the highest
position.
From the mode of operation of the apparatus hereinbefore described it will be
noted that a number will always be visible through the apertures in the cover of
the casing corresponding to the number of picks made (revolutions of the
picking eccentric shaft) and having as many places or numbers of figures as
desired by suitably increasing the number of the shafts C.
An essential peculiarity of this apparatus consists in the fact that by merely
opening the cover and rotating the several number-wheels by hand the apparatus
can be set to zero.
Other counting apparatus render it necessary that the main shaft shall cither be
turned back or that the apparatus be rotated to the next following zero position.
It may also be stated that all the pins F are shown in the drawing by way of
illustration in the vertical position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In a counting device for power looms or other purposes-the arrangement
and combination of a series of independently mounted and disconnected number-
wheels a series of studs or. pins arranged concentrically around the side face of
each said wheel and projecting therefrom and a long finger or arm mounted at
right angles on the shaft of each said number-wheel said arm being adapted to
engage once in each revolution with the aforesaid projecting pins on the next
adjacent number-wheel and which lie in the path of travel of said arm and thereby
the counting is effected substantially in the manner and for the purposes herein-
before set forth.
2. The improved counting device arranged constructed combined and acting
substantially in the manner and for the purposes hereinbefore described and
illustrated in the drawings hereuuto annexed.
