A Method of and Apparatus for Removing Cops Doffed from the
Spindles of Mules, Ring-spinning, and certain other Machines.
1, HENRY BERNOULLI BARLOW, of 17 St. Ann's Square, Manchester in the County
of Lancaster, Consulting Engineer and Patent Agent, which invention has been
communicated to me from abroad by James Gibson Scott, of 40 Forbes Street,
Bombay, Engineer, do hereby declare the nature of this invention to be as follows:-
:―
This invention broadly stated consists in the arrangement use and application of a
movable apparatus or elevator to facilitate the removal of doffed cops from mules,
ring-spinning frames and certain other machines.
This apparatus or elevator may be suspended by ropes chains or equivalents or may
be otherwise movably arranged so that when not in use it may be raised above or
otherwise placed clear of the mule or other machine to which it is applied. Prior to
the doffing operation the apparatus is lowered or otherwise moved into a convenient
position and held there by a catch, the doffer places the cops into the apparatus as
quickly as he can doff them. As soon as the doffing is finished the catch is released
and the apparatus with the cops is raised or moved out of the way by the action of
counterweights or other means.
The apparatus may be emptied at any convenient time say during the interval for
one of the meals so that no time may be wasted. To effect this the apparatus is
lowered or moved into the required position and the cops discharged by means of
a travelling endless belt or lattice which carries the cops to one end where they fall
into a skip or other receptacle; or where no travelling belt is employed one end of
the apparatus may be depressed to allow the cops to run down into the receptacle.
From the foregoing description it will be readily understood that the apparatus or
elevator is actually a long doffing box or trough which is supported immediately in
front of the doffers and can be regulated to any height most convenient. The apparatus
preferably extends from end to end of the mule or machine and is made somewhat
broader inside than the full length of a cop so as to allow the travelling belt to deliver
the cops freely at one end.
Some of the chief advantages obtained by the use of the apparatus are that the
present objectionable system of carrying the cops in the arms of the doffers to the end
of the mule or machine is avoided, there is no longer any danger of the cops being
roughly bandled and a great saving in time and labour is effected.
Various modifications in the apparatus might be made without departing from the
nature of the invention as above described. For example instead of a travelling belt
a series of short doffing boxes might be arranged inside the apparatus on wheels or
rollers so that when the apparatus was inclined the boxes would travel to the depressed
and and their contents could be discharged into a receptacle below, or the bottom of
the apparatus might be made in sections each section being hinged and about as long
as an ordinary doffing box so that at the proper time the doffed cops could be allowed
o fall through into doffing boxes below.

A Method of and Apparatus for Removing Cops Doffed from the
Spindles of Mules, Ring-spinning, and certain other Machines.
I, HENRY BERNOULLI BARLOW, of 17 St. Ann's Square, Manchester, in the County
of Lancaster, Consulting Engineer and Patent Agent, do hereby declare the nature
of this invention which has been communicated to me from abroad by James Gibson
Scott, of 40 Forbes Street, Bombay, Engineer and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention broadly stated consists in the arrangement use and application of a
movable apparatus or elevator to facilitate the removal of doffed cops from mules,
ring-spinning frames and certain other machines.
This apparatus or elevator may be suspended by ropes chains or equivalents or may
be otherwise movably arranged so that when not in use it may be raised above or
otherwise placed clear of the mule or other machine to which it is applied. Prior to
the doffing operation the apparatus is lowered or otherwise moved into a convenient
position and held there by a catch, the doffer places the cops into the apparatus as
quickly as he can doff them. As soonas the doffing finished the catch is released
and the apparatus with the cops is raised or moved out of the way by the action of
counterweights or other means.
The apparatus may be emptied at any convenient time say during the interval for
one of the meals so that no time may be wasted. To effect this the apparatus is
lowered or moved into the required position and the cops discharged by means of a
travelling endless belt or lattice which carries the cops to one end where they fall into
a skip or other receptacle; or where no travelling belt is employed one end of the
apparatus may be depressed to allow the cops to run down into the receptacle.
From the foregoing description it will be readily understood that the apparatus or
elevator is actually a long doffing box or trough which is supported immediately in
front of the doffers and can be regulated to any height most convenient. The
apparatus preferably extends from end to end of the mule or machine and is made
somewhat broader inside than the full length of a cop so as to allow the travelling belt
to deliver the cops freely at one end.
Various modifications in the apparatus might be made without departing from the
nature of the invention as above described. For example instead of a travelling belt
a series of short doffing boxes might be arranged inside the apparatus on wheels or
rollers so that when the apparatus was inclined the boxes would travel to the depressed
end and their contents could be discharged into a receptacle below, or the bottom of
the apparatus might be made in sections each section being hinged and about as long
as an ordinary doffing box so that at the proper time the doffed cops could be allowed
to fall through into doffing boxes below.
And in order that this invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a front elevation illustrating the invention as applied to a self-acting
mule.
Figure 2 is an end elevation showing the doffing troughs and boxes in two
positions.
Figure 3 is a transverse section on a larger scale of one of the troughs and doffing
boxes.
The doffing apparatus or elevator herein before described is in these views shown as
consisting of a long trough a containing any convenient number of doffing boxes b
and is suspended by ropes or equivalents e passing over pulleys d supported by the
roof of the spinning room or otherwise, the ropes c being weighted by sand bags or
other suitable weights e. The doffing boxes b are preferably mounted on antifriction
C

page_text: rollers so that when one end of a trough a is depressed the filled boxes will readily
travel to that end.
On the left-hand side of Figure 2 the doffing apparatus consisting of the trough a
with its doffing boxes b is shown raised out of the way and clear of the spindles f on
the mule carriage g whereas on the right-hand side of the same figure the apparatus
is shown lowered in position ready for filling the boxes 6 with cops doffed from the
spindles f.
Some of the chief advantages obtained by the use of the apparatus are that the
present objectionable system of carrying the cops in the arms of the doffers to the end
of the mule or machine is avoided, there is no longer any danger of the cops being
roughly handled and a great saving in time and labour is effected.
Having now particularly described and ascertained the nature of this inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed I declare that what 1 claim is:-
1. The herein described method of removing doffing cops by means of a movable
doffing apparatus arranged in the manner herein set forth or in an equivalent manner
substantially as specified.
2. The arrangement use and application of a movable trough a combined with doffing
boxes b or their equivalents substantially as and for the purposes herein described
and as illustrated by the drawings annexed.
