A communication by ALBERT KOECHLIN, of 8 Spiegelvorstadt, Mülhausen,
Alsace, in the Empire of Germany, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham in
the County of Warwick, and 31 High Holborn in the County of Middlesex,
Civil Engineer, 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 has for its object to provide an easy and completely reliable
means whereby any spinning mill manager may ascertain the twist, the time of the
drawing out and running in of the carriage and the speed of the spindles.
Instead of measuring the speed of the spindles as hitherto by placing and
pressing on the spindles a device for indicating the revolutions, which device, by
the resulting friction, caused a diminution of the speed of the spindles, this
improved arrangement takes as starting point, the mechanism which drives the
spindles, that is the spindles-drum instead of the spindles themselves.
It is hereby assumed that the irregularities which cannot be avoided in the
transmission of movement from the drum to the spindles, and from machine to
machine remain uniform and therefore do not essentially affect the results.
For this purpose there is arranged on the shaft of the spindles-drum, as shown in
Figure 1 of the accompanying drawings, a single or multiple threaded endless
screw I which engages with a wheel I having 40 teeth, the shaft III of which
wheel is formed with a squared end IV, Figure 1. This squared end IV fits into
a recess IV (Figure 2) of a shaft which is provided with a 68 wheel forming part
of a double clockwork U U₁, one part U of which is a clockwork indicating of a
second, which will be referred to as the "seconds" clockwork whilst the other I'
is driven by the 68 wheel, the latter engaging for the purpose in a 42 wheel, on
the arbor of which a 12 pinion and a large pointer or finger are mounted.
The 12 pinion operates a 24 wheel, the 10 pinion of which revolves a 50 wheel,
on the arbor of which a small pointer or finger is mounted which indicates the
number of revolutions of the larger pointer. The seconds clock-work U has
for its object to indicate the time during which the adjustment takes place, in order
that all estimates may be exactly referred back to the time.
Both clock works may be simultaneously set in motion by means of a peculiar
form of construction, and may be again simultaneously arrested, and returned
to zero.
This is effected as follows:-
A bar b. provided at its upper end with a button a, passes through the clockwork
and encounters a pin c which is constantly pressed upwards by means of a spring
and a lever d'elf. On the bar is a projection y which encounters a lever def
pivoted on e. This lever def has at one end a hook which engages in a ratchet
wheel and is pressed constantly towards the bar b by the action of a flat spring x.
The hook fis bent to pass through a slot g in the frame plate, the slot being of
sufficient length to allow the hook a certain play. On the ratchet wheel h
projections are arranged. A lever ip u revoluble on p and acting under the

page_text: pressure of a flat spring m is constantly pressed against the centre of the ratchet
wheel h. If it stands on the projections, the end u of the lever ip u arrests the
balance P of the seconds clockwork. A peculiarly shaped lever k also presses
(under the action of a spring n) on the wheel h V, which lever when engaging with
the projections V is thereby held away from an eccentric g attached to the arbor
of the large pointer. If the lever k drops into the recess between two projections V,
a nose on the lever k comes against the eccentric q and holds the latter fast. A
lever presses against the lever k by the action of a spring o, and, similarly to the
lever k, either releases or retains the eccentric r which is mounted on the arbor of
the small minute pointer. The second clockwork U₁ serves for estimating the
twist by units of length. It is provided with a similar device to that above
described for throwing it out of gear and for returning it to zero, consisting of a
pin c which presses on a lever d'e' f' pivoted on e¹. This lever d'elf is provided
at one end with a hook f' which engages in a ratchet wheel and is constantly
pressed to the right by the action of a spring 2. This hook f¹ is bent to pass
through and move in a slot g' formed in the frame plate. Projections V₁ are
arranged on the ratchet wheel h'. A lever i p¹ u¹ pressed upwards by a spring m³
bears against the wheel V. If the lever i rest on the projections V1 of the
ratchet wheel, the lever arm u¹ presses upwards against a double levert t¹ D
forming a brake, which lever under the action of the flat spring is constantly
pressed against the lever pu. The part D which is formed as a brake block
cannot therefore reach the brake wheel and thus allows the latter to move. If the
wheel h¹ be so turned that the end of the lever i¹ pu' falls into a recess, the
part (of the lever i plu¹) which is formed to act as a brake, presses against
the brake wheel A and stops the latter. At the same time the end p' u¹ of the
lever pu¹ moves downwards. The lever t t D pivotted at t makes a corre-
sponding oscillation and brakes the brake wheel B. The pointer is returned to
zero as in the previous_clockwork by the wheel h¹ V₁, levers k' ', springs n¹ z and
the eccentrics 19. The pawls J J in both clockworks retain the ratchet
wheels or ¹ respectively.
The working of this improved twist and speed measurer for self-acting mules is
as follows:
The clockwork is placed with its square recess IV1 (Figure 2) on the squared
end IV of the shaft III (Figure 1). The moment the carriage begins to move
outwards the button a of the clockworks U U₁ is pressed down, by which means
the working parts of the clockwork assume the position indicated. The seconds
clockwork U now commences to work as the lever u no longer retains the balance P,
and the twist measurer is set in operation by the 68 wheel. All four pointers
work until the spindle carriage has again returned to its first position. A second
pressure then takes place on the button a, by which means the levers def
and def, and the hooked ends fand f¹ of said levers are moved forward one tooth.
The lever ipu thus comes to rest on a projection V, and stops the seconds
clockwork. Simultaneously the lever k rests on the projection on which it was
lifted by the first pressure on the knob and neither k nor I make any movement.
In the lower clockwork U' by the second pressure on the knob, the ratchet
wheel is also moved forward one tooth, by which means the nose 1 of the
lever puenters one of the recesses, and the braking of the brake wheels A
and B by means of the levers i¹ pu¹ and Dtt takes place. The lever k¹ in a
similar manner to the first clockwork here also remains lying on a projection V¹
and neither it nor the lever moves. The time of the drawing out and running in
movement of the machine may then be read off by means of the minute and
seconds pointers, and the twist that the thread has received will be indicated on
the dial of U. Instead of effecting the pressing down of the knob by hand, the
clockwork may be set in movement or thrown out of gear from the machine by
means of a suitable lever or levers.
The indicators are mounted on their arbors loosely with slight friction, so that
when they are braked they will be blocked without interfering with the continued

page_text: working of their arbors; otherwise the whole apparatus would spin round on the
pin IV.
The blocking of the indicators qrqr¹ and the moving of the mechanism to
zero will be better understood by reference to Figures 3, 4 and 5 of the drawings
which each show a different position of the eccentric q at the three moments of the
return to zero. The lever k stands in the position I when the clockwork is going,
that is to say after the first pressure on the button a when a twist is being
measured. If the measurement be completed and the clockwork stopped by a
second pressure on the button a, the lever k will still remain in this position. A
third pressure on the button a will now effect the return to zero by the projection V
moving from under lever k, thus allowing the latter to fall into one of the recesses
between the projections V, whereby the said lever & will, under the action of the
spring, strike against the eccentric 7, encountering the latter in the dotted
position II and under the continued pressure of said spring will move the eccentric
into position III.
In order that this twist measurer may indicate the twist per centimetre, the
wheels are arranged as follows:-
In order to give a twist equal to 1 per centimetre thread, the spindles must, on
the outward movement of the carriage, make a number of revolutions which is
equal to the number of units indicated in centimetres of the outward movement of
the carriage.
If we take 162 centimetres as the length of the drawing out movement, the
squared end then makes on the outward movement of the carriage and in
the case of a twist equal to 1 per centimetre a number of revolutions equal
162 x 2.35 × 1 24-7207
to
=
40
if the diameter of the spindle wharve be 2.35 centi-
15.40 x 40
metres, and that of the spindle drum be 15.40 centimetres. The large pointer on the
1 68
40 42
axle q' then makes one revolution, consequently 24-7207 x × = 1.000599 = 1.
As however the course of the larger pointer is divided into 100 equal parts, it
shows T of units of twists per centimetre. The smaller pointer on the axle r
travels slower, and shows the units of the twist.
By means of this twist measurer there may be ascertained
1. The time employed in the drawing out movement of the carriage;
2. The determination of the twist of the thread on the machine;
3. The determination of the speed of the spindles.
For the above purposes the apparatus is placed on the square pin IV of the
shaft III which is driven from the drum shaft by the endless screw I. If the
carriage be running out, pressure is applied to the button a, whereupon the seconds
clockwork and the "twist" clockwork are released and revolve until a second
pressure on the button stops both of them. The seconds clockwork then indicates
the time during which the measurement lasted. If the measurement be limited to
the movement outwards, the seconds clockwork indicates the time occupied in the
running out.
When the reading of the "twist" clockwork has been taken, it is sufficient to
press on the button a a third time, to return all the pointers to zero.
The determination of the maximum speed of the spindles is effected by means of
the clockwork as follows:-
The clockwork is started only at of the course of the carriage and is stopped
shortly before the end of the complete outward movement. The seconds
clockwork indicates the duration of the time, and the twist clockwork the number
of twists made per centimetre; for instance, the seconds clockwork shows
4.5 seconds and the twist clockwork 3.1275. As each revolution of the axle q¹
corresponds to 162 revolutions of the spindles, the spindles make in 4.5 secouds &

page_text: number of revolutions equal to 3.1275 x 162
-
506 65 revolutions. The maximum
506.65 x 60
= 6755 revolutions.
4.5
speed of the spindles per minute is therefore
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
A new or improved twist and speed measurer for self-acting mules, operated
from the spindles-drum by means of an endless screw 1 and consisting of a double
clockwork (U U¹) one of which indicates the time in th of seconds and the other
the twist in oths of units, which clockwork may be simultaneously started,
stopped and returned to zero by pressing on a knob (a), which so operates pawls or
pawl levers (d, e, f: d', e, f¹) and special ratchet wheels (4, 1) that levers (i, p, u;
, p, u; k; ; D ', t) under the action of springs (m no, x m' n', 2, 1, 2²)
effect the starting, stopping or returning to zero of the pointers substantially
as herein before described and illustrated.
