I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Heinrichs Westerheide of Schiffbeck, near Hamburg,
Germany, Spinmaster; to be as follows:
In the apparatus for braking the bobbins of spinning machines and the like
hitherto known, every braking cord is strained separately. This process which
requires that the operator attending the machine should be an exceedingly careful
person, is repeated in changing every bobbin.. Furthermore the weights used in
the braking apparatus hitherto known are inconvenient inasmuch as they fall down
and run away in the event of the cord being broken.
By this invention the person attending the machine is enabled to ship and
unship the whole number of braking apparatus by a single manipulation, change of
the intensity of the braking powers of any of the brakes being thus avoided. But
the intensity of the braking power of each brake may be regulated independently
from that of the others. This object is effected substantially in the following
manner: one end of the braking cord is fastened to a fixed point and the other
is joined to a bar, which is common to all the brake cords and movable in a definite
manner. Furthermore every braking cord is provided with a special straining
device. The bar is moved only when the bobbins are to be changed. In some
cases both ends of the cords may be joined with the aforementioned bar, the
movement of the latter being preferably such that it is always parallel with the
horizontal line passing through the axes of the bobbins of one row. In some cases
also both ends of one and the same braking cord may be joined with one and the
same bar. One end or both ends of the braking cords inay also be provided with a
spring in order to reduce the strain to be exerted on the circumference of the
bobbin. Furthermore at one end of the braking cords or at both ends of, them
may be arranged a thread so as to regulate the tension of the spring or of the
braking, cord itself. Any other suitable device may be used instead of the
thread.

I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
London, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Heinrich Westerheide of Schiffbeck, near Hamburg,
Germany, Spininaster, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
In the apparatus for braking the bobbins of spinning machines and the like
hitherto known, every braking cord is strained separately. During the last few

a bar in the direction of its axis, that is to say this bar is provided with notches.
each of them forming the support of one of the cords the tension of which is effected
by means of weights in the usual manner. In such an arrangement the tension
itself will be always the same. There will be changed only the length of that part
of the cord which surrounds the whirl or the bobbin itself. The aim of the present
invention is to change also the tension of the cord, this effect being rendered
possible equally whether the above mentioned length of the cord surrounding the
whirl is changed or not. This purpose is effected substantially by fixing one end
of the cord to the frame of the machine, while the other end is joined to a bar
which can be moved in such a manner that it always remains parallel to its original
position. In some cases also both ends of the cord are fixed to one and the same
bar, that is to say the plan view of a cord is U shaped. Such a braking apparatus,
furthermore obviates the inconvenience which is caused by the loss of the weights;
as these weights are superfluous.

The accompanying drawings represent several modifications of a braking
apparatus for the bobbins of spinning machines and the like improved in the above
mentioned manner.
The first modification is illustrated by Figure 1 as combined with a spinning
machine and shewn in a vertical section; Figure 2 is a front elevation of the
copping rail; Figure 3 is a plan of Figure 2 and Figure 4 is a section on the
line, Figure 2 and Figure 5' is a section on the line of Figure 2.
Figure 6 is a detached plan of the parallel moving bar and Figure 7 is a section on
the line Figure 6.

The second modification is represented by Figures 8 & 9 in a plan and a section
on the line y-y Figure 8 respectively. Figure 10 is a plan and Figure 11 a
section on the line Figure 10, both figures representing a third modification..
Like letters of reference denote like parts throughout the several views.
C
In the form shewn in Figures 1 to 7 à horizontal bar, b has been arranged at the
inward side of the copping, bar a. Through the holes 6' of this bar have been
passed hooks e in such a manner that the hook proper c reaches to, the outward'
side of the copping bar. That end of the shank of the hook c which projects
inwardly is surrounded by a helical spring d. One end of the latter bears against
the inner face of the bar, the other one against a nut e screwed on the shank of the
hook c. By such an arrangement each cord fjoined with this hook is attached in
an elastic manner. The cords f are then put around the bobbing and led to a
second hook which, is attached to a second bar k by means of a pin in such a
manner that it may be turned round a vertical axis. This purpose is effected
substantially by causing these hooks to pass through a slot k in this bark (see
Figure 2). The bar is furnished with a great number of holes k² in such a
manner that every pin may be put into one or other of them so as to effect a
regulation of the tension of the cords when required. The bar is held in its
position with reference to the copping bar by means of its loops provided with
longitudinal slots through which are passed the set screws 7 (see Figures 3 & 5).
In order to give to the operator of the machine a stop so as to enable the bar k to
be brought back by means of a longitudinal movement into its original position,
after the cords have been loosened a bow.m is fixed to the underface of the copping
bar a (see Figures 2, 3 and 4). This bow is furnished with a slot m² (see Figure 2)
through which passes a handle a affixed to the bark which handle n is secured to
the bow m by means of a pin o passed through one or other of the holes m³ in the
bow n..
k
In the arrangement shewn in Figures 8 and 9, the bar k is supported by two
horizontal arms.p linked to the copping bar a. One of these arms p is provided
with a handle p. The latter and a bow g of the copping bar a serve to change the
position of the bar k.
In the modification shewn in Figures 10 and 11 both ends of the cords fare
attached to one and the same movable bark

page_text: Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus for braking the bobbins of spinning machines and the like the
combination with the cords f of a hook c attached to the copping bar a and of a
second hook attached to a bar the latter being movable substantially as set
forth with reference to Figures 2 to 7 and 8.& 9 of the annexed drawing and for
the purpose specified.
2. In apparatus for braking the bobbins of spinning machines and the like the
combination with a cord f of a hook c, of a hook hand of a bark, the hook has
well as that denoted by c being attached to this bar, which is caused to move.
