I, DANIEL STANDRING INGHAM of Highgate Terrace Wakefield Road Dewsbury in
the county of York Doffing Plate and Machine Maker do hereby declare the nature
of my invention for IMPROVEMENTS IN THE CONSTRUCTION OF CONDENSER BOBBINS
OR SPOOLS to be as follows:-
The object of this invention is to attach the Metal head of the Bobbins upon the
Wooden Barrel so that the Barrel carries the head, instead of the Gudgeon Bolt or
metal cap as is the case in Bobbins at present in use. This I accomplish by turning
down to the depth of of an inch, and of an inch long the end of the Barrel for the
reception of a Hoop, which may be flanged or otherwise, and which has two lugs on,
and which I insert into the Barrel end to the extent of 1 inches, more or less, letting
it stand out faceable with the part of the Barrel projection on which it rests, and thus
makes a safe and secure rest or seat for the metal head, hole made to fit the end of
the inserted hoop which projects from the end of the Barrel.
Or I may vary the method of construction by having a metal washer in the form
of a Maltese Cross with a slight projecting boss on each side, the whole of which is
let into the end of the wooden Barrel, the wings of the washer being faceable with
the end of the Barrel, and one side of the projecting Boss standing forward to receive
the metal head, which has two luggs on to prevent the head working round.
The wings are also made in the shape of a V at the end, and fit into a V shaped
hole in the outer hoop, thus making a compact fixture resting entirely on the wood,
the whole being made fast by a bolt through the Barrel, and a Nut or screwed Washer
at each end.

Improvements in the Construction of Condenser Bobbins or Spools.
I DANIEL STANDRING INGHAM of Highgate Terrace Wakefield Road, Dewsbury
Yorks Machine Maker and Doffing Plate Manufacturer do hereby declare the nature
of my invention for IMPROVEMENTS IN THE CONSTRUCTION OF CONDENSER BOBBINS OR
SPOOLS and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of this invention is to attach the metal heads of Condenser Bobbins in
such a way that the weight and strain is carried by the Wooden barrel instead of the
gudgeon bolt or metal cap, as is the case in the Bobbins at present in use.
This I accomplish by turning down the Wooden barrel to the thickness required A
Fig. 1 and bore a hole either through the centre or to the requisite depth according
to the bolt to be used, I then turn down the end of the barrel A Fig. 1 to a slightly
smaller diameter B Fig. 1 and thus leave a slight projection to receive a hoop A Fig. 2
which may be flanged or not as required, Upon the hoop I leave a beading on
opposite sides, The Metal head Fig. 3 has a hole made in the centre large enough to
receive the hoop. When the metal head has been placed upon the hoop Fig. 2 the hoop
is then placed upon the projection B Fig. 1 at the end of the barrel and either pressed
into it or by removing the beading and screwing a thread on five sixths of its entire
length, it may then be screwed into the barrel till the metal head Fig. 3 becomes
perfectly tight between the Bobbin end and the Flange on the hoop, and the Flange
on the hoop becomes level with the projection B Fig. 1. Thus the weight of the
metal head rests on the hoop at its base, and the hoop into B Fig. 4 and on the barrel
end. The weight of the whole being borne by the barrel and the metal head made
secure without any other fixing Fig. 4, I then insert a bolt Fig. 7 wholly or partially
through the barrell, which has turned ends to act as pivots or axles and are also
screwed to receive a nut Fig. 5 or washer, which when screwed tightly up to the metal
head overspans the flange of the hoop, and binds the metal head still more firmly
against the bobbin end B Fig. 6 and prevents the displacing of the hoop on its coming
loose, adding very much to the strength and durability of the Bobbin A, Fig. 6.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is:
1st. The construction of Condenser Bobbins on the principle herein described with
a hoop inserted into the end.
2nd. The Flanged hoop with its bead A Fig. 2.
