page_text: Date of Application, 10th June, 1899-Accepted, 26th May, 1900
We, WILHELM JACKSON and JOSEPH BARTHOLEMY, Spinners, both of Reine,
Westphalia, 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 present invention relates to a device for disengaging self-actors and the
particular object of the invention is to enable the man working the machine to
throw the latter out of gear by moving the disengaging rod directly by hand as
well as indirectly by moving another rod mounted horizontally on the carriage
of the self-actor and being adapted to be lengthwise reciprocated across to the
direction of the motion of the carriage of the self-actor.
By means of this rod the self-actor can be stopped, if the carriage of the same,
whilst running in, arrives at the end point of its way. But the whole machine
can also be stopped by means of this rod at any point of the way of the carriage
when this is running in, as well as running out.
In order that the invention may be more clearly understood, reference is to
be had to the accompanying drawings in which.-
Figure 1 is a side view of the device; the frame of the self-actor as well as the
carriage are indicated only by dotted lines.
Figures 2 and 3 respectively are cross sections on the lines 2-2 and 3-3 of
Figure 1, and
Figure shews the device in another position.
In the drawing (2) is the disengaging rod, which by means of a handle (10) can
be moved in the direction of the arrow (11), thereby stretching the spring (17).
That end of the rod (2) which carries the handle (10) rests in a guide (3), whilst
the other end is pivotally attached to a bell crank lever (18) pivoted on the frame
of the machine, as is clearly shewn in Figure 1. The rod (2) is provided with a
projection (1), which under the tension of the spring (17) is normally resting
against the side face of the guide (3).
In this position of the disengaging rod (2) the main driving belt by means of
the rod (12) and the belt fork (coupled with this rod but not shewn in the drawing)
is held on the fixed driving pulley of the countershaft, located beneath the ceiling
of the workshop. Parallel to the beforementioned rod (2) is arranged the rod (5),
the ends of which are cylindrically turned, whilst the middle part is rectangular
in cross section. The rod (5) rests in the brackets (4) and carries, rigidly fixed
thereon, near the handle (10) of the rod (2), a lever (28), the free end of the latter
extends under the rod (2) but as will be clearly seen in the drawing there remains
a certain space between the lower edge of the rod (2) and the upper end of the
hook or lever (28).
By turning the rod (5) a certain amount in the direction of the arrow (13),.
Figure 3, the lever (28) rises the rod (2) until the projection (1) loses its support
on the side face of the guide (3) whereupon the spring (17) draws the rod (2)

page_text: back against the direction of the arrow (11) Figure 1, and at the same time
turns the bell crank lever (18) downwards. The rod (12) is thereby also moved
downwards, and by means of its belt fork (not shewn in the drawing) leading
the driving belt from the fixed driving pulley over upon the un-fixed pulley of
the counter shaft, stops the machine.
Instead of by the lever or hook (28), the rod (2) may be raised by hand by
means of the handle (10).
In order to enable the workman who is standing near the carriage (26) to
turn the rod (5), so as to throw the machine out of gear at any point of its
forward or backward movement, there is arranged an arm (7) embracing by
means of its forked end (29) the rectangular part of the rod (5) and being guided
on this rod by a roller (6), Figures 1 and 2.
To the lower end of the arm (7) is pivoted a striking piece (9) and through this
piece runs a rod (27), the length of which is about equal to the length of the
carriage (26). The latter in its smaller elevation and by dotted lines is shewn
in the drawing. The striking piece (9) is by means of a bolt (15) pivoted to
the horizontally located rod (27) and this latter rests in suitable bearings mounted
on the carriage (26).
In its normal working the carriage is running in corresponding to the direction
of the arrow (16) and after having reached its left hand end position the carriage
returns opposite to the direction (16) without altering anyhow the stopping
gear (25) or (2). As the arm (7) pending on the rod (5), and also the rod (27)
being connected with the carriage, all these parts, (27) (9) and (7), will be moved
or drawn with the carriage in each direction of its movement, that is to say, in
the direction of the arrow (16) as well as opposite thereto. When the carriage in
its normal working reaches its left hand end position (Figure 1) the piece (9)
will pass by and not touch the rod (25). The said rod (25) being guided by the
brackets (31) (48) and held in its normal position by a spring (19) as indicated in
Figure 1. The spring is located on the rod (25) between the bracket (31) and
collar (32) of the rod (25). A collar (20) is also fixed on the rod (25) resting, in
the normal position of the latter, against the left hand face of the bracket (48) and
preventing the rod (25) overshooting or going beyond its proper position opposite
to the direction of the arrow (22) Figure 1.
If the workman wishes to stop the machine, for instance if it is necessary to
place bobbins in positions or for any other reason, he moves by hand the rod (27)
in the direction of the arrow (21), Figure 2, until the piece (9) comes in straight
line with the rod (25). The piece (9) will as soon as the carriage reaches its end
position, push the rod (25) in the direction of the arrow (22) and cause the left
hand end of the rod (25) to strike against and turn a belt fork (23) so much that
the belt running through this fork will be thrown from its fixed driving pulley
to its unfixed pulley, thereby stopping the machine. When the belt governed by
the fork (23) is thrown upon its unfixed pulley the beforementioned counter shaft
located below the ceiling of the workshop is running free further, as this shaft is
only stopped by moving the rod (2) opposite to the direction of the arrow (11),
Figure 1; it will be understood that this latter belt running through the fork (2)
is directly driving the machine, but being itself driven and receiving its force
by a pulley, rigidly fixed on the main counter shaft beforementioned and located
below the ceiling of the workshop.
If the workman on the other hand wishes to stop the machine whilst the carriage
is running in but is still far from its end position or whilst the carriage runs
out opposite to the direction of the arrow (16), he moves the rod (27) by hand
considerably more than in the first case in the direction of the arrow (21) Figure 2
so that the rod (5) will by means of the forked arm (7) be much more turned, than
in the first case, by means of the lever (28) rising and releasing the rod (2). The
said rod (2) will then by means of the spring (17) be moved in the beforementioned
manner opposite to the direction (11) and by throwing the driving belt of the
ceiling counter shaft from its fixed pulley to its unfixed pulley stop the machine.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
•
A stopping device for self-acting mules, consisting of a rod (27) running over
the whole length of the carriage (26) and being, by means of a striking piece (9)
and a forked lever (7), connected to another rod (5) which is located at right
angles to the aforesaid rod (27) and parallel to the direction of movement of the
said carriage (26); the piece (9) being adapted after moving the rod (27) a certain
distance lengthwise, to throw by means of a rod (25) and a belt fork (23) the
secondary driving belt from its fixed pulley over on to its unfixed pulley, whilst a
lever (28) rigidly fixed on the rod (5), after a longer length movement of the
rod (27), will release a rod (2) which, being now by means of a spring forced back
in the opposite direction to the arrow (11), will throw the primary driving belt
from its fixed pulley over on to its unfixed pulley and thereby stopping the
machine.
