Improvements in the Construction of Condenser Bobbins or Spools.
DANIEL STANDRING INGHAM and OSWALD HOOKER INGHAM Clover Works
Dewsbury Yorks. Machine Makers do hereby declare the nature of this invention
to be as follows:-
This invention has reference to that class of bobbin or spool called a condenser
bobbin, and used in woollen and other yarn spinning. These bobbins are usually
made with wood or iron barrels, with steel or other metal or wood flanges or heads,
which have been held in position on the barrel end, by either a short bolt inserted
into the barrel end and screwed into a nut, or by a bolt put through the whole
length of the barrel and an outer collar or screwed washer screwed on to the bolt
end to hold the metal head to its place. Sometimes the metal head is made to rest
on the bolt only, sometimes by being screwed to the barrel end with ordinary
screws, and sometimes resting on a very slight projection on the metal cap fitting
the bobbin end. None of these principles of construction have been satisfactory,
because of the heads dropping from the barrel when the nuts or washers have come
loose, and being only a plain thin disc (when thrown down) becomes bent and out
of shape, and also cuts the floors doing great damage.
Our invention consists in improvements removing the defects named. We place
a malleable iron or other metal cap or hoop cast in one piece on to the end of the
bobbin barrel, whether of wood or iron, with a square projection in the centre at the
outer end to carry the metal head, also having in two or more parts further
projections or midfeathers, so that when the metal head has been placed in position
on the square projection of the metal cap, we then turn back the midfeather
projections against the head, and by that means make the head secure on the barrel
independent of the bolt, preventing it from falling from the barrel if the bolt, or nut,
or washer, should give way or come loose, thus leaving the bolt to act simply as a
pivot.
In order to prevent the metal heads or flanges from bending when thrown, down,
I have them slightly corrugated vertically, which adds very much to their resisting
power, and strength, and also enabling me to use a lighter metal than formerly, and
reducing the weight of the bobbin.
We also have a slight flange of about one eighth of an inch broad pressed up on
the outer edge of the metal head, thus presenting a larger surface to the floor and
therefore doing less damage.

DANIEL STANDRING INGHAM and OSWALD HOOKER INGHAM Machine Makers
Clover Works Dewsbury Yorks. 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 reference to that class of bobbin or spool called a condenser
bobbin, and is used in woollen and other yarn spinning. These bobbins are usually
made with wood or iron barrels, with steel or other metal or wood flanges or heads,

into the barrel end, and screwed into a nut, or by a bolt put through the whole
length of the barrel, and an outer collar or screwed washer screwed on to the bolt
end to hold the metal head to its place. Sometimes the metal head is made to rest
on the bolt only; sometimes by being screwed to the barrel and with ordinary
screws; and sometimes resting on a very slight projection on the metal cap fitting
the bobbin end.
None of these principles of construction have been satisfactory, because of the
heads dropping from the barrel when the nuts or washers have come loose, and being
only a plain disc when thrown down becomes bent and out of shape; and also cuts
the floors doing great damage.
Our invention consists in improvements removing the defects named.
We place a malleable iron or other metal cap or hoop cast in one piece on to the
end of the bobbin barrel, whether of wood or iron, with a square projection in the
centre at the outer end to carry the metal head; also having in two or more parts
further projections or midfeathers, Fig. 1ª, so that when the metal head has been
placed in position on the square projection of the metal cap, we then turn back the
midfeather projections against the head, Fig. 24, and by that means make the head
secure on the barrel, independent of the bolt, preventing it from falling from the
barrel if the bolt, or nut, or washer should give way or coine loose, thus leaving the
bolt to act simply as a pivot. In order to prevent the metal heads or flanges from
bending when thrown down, we have them slightly corrugated vertically, Fig. 2³,
which adds very much to their resisting power and strength, and also enabling us to
use a lighter metal than formerly, and reducing the weight of the bobbin. We
also have a slight flange of about one eighth of an inch broad, pressed up on the
outer edge of the metal head, and we may if required alightly turn in the outer
edge of the flange, thus presenting a larger surface to the floor and therefore doing
less damage. Fig. 4.
Having now described the nature and object of our said invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, we wish it to be understood that what we claim as our invention, is the
construction of condenser spools or bobbins substantially in the manner hereinbefore
described, and represented in the drawings annexed.
1. We claim the construction of the metal head with a flange on the outer
edge Fig. 3.
2. The vertical corrugated heads Fig. 2.
3. The projecting wings or midfeathers cast on the outer end of the hoop
Fig. 14.
4. The method of pressing back the wings or midfeathers against the metal
head Fig. 24.
Substantially in the manner and for the purposes above set forth.
Dated this 2nd day of February 1892.
