Improvement in Drum Winding Frames.
I JOHN LORD of Tatton Mills, Ordsal Lane, Salford in the County of Lancaster
do hereby declare the nature of this invention to be as follows:-
My invention relates to drum winding frames and my improvement consists in
the addition of a cam lever applied to the "latch and catch" motion and of a
thumb lever attached to the "bobbin cradle" for raising and lowering said cradle,
the object of my invention being to prevent the sudden starting of the rotation of
the bobbin by its being too quickly dropped upon the drum, as is usually the case
with the ordinary arrangements, and the consequent breaking of the yarn by the
sudden jerk. I effect this object by means of a thumb lever formed on or attached
to the cradle and a cam formed on or fixed to a lever working on a round rod, stud
or peg behind the cradle. The cam part works or bears against a peg or stud cast
upon or otherwise fixed to the latch. The cam lever on being pulled by the fore-
finger of the operative lifts the latch and liberates the cradle which would fall if
it were not held up at the same time by the operative pressing the thumb against
the thumblever on the cradle and letting the bobbin down gently upon the drum
so that the bobbin starts slowly to rotate and does not jerk the yarn so as to
break it.

Improvement in Drum Winding Frames.
1, JOHN LORD of Tatton Mills, Ordsal Lane, Salford in the County of Lancaster,
Mill Manager 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:-
"
My invention relates to drum winding frames and my improvement consists in
the addition of cam levers or their equivalents applied to the "latch and catch
motions and of thumb levers attached to or formed on the "bobbin cradles" of said
frames for the purpose of raising and lowering said cradles, the object of my
invention being to prevent the sudden starting of the rotation of the bobbins by
their being too quickly dropped upon the drums as is usually the case with the
ordinary arrangements, and the consequent breaking of the threads by the sudden
pull or jerk. effect this object by means of a thumblever and cam lever arranged
for each bobbin, the camlever working on a round rod, stud or peg behind the
bobbin cradle and consisting of a lever formed with or having attached to it a cam
or its equivalent which bears or acts on a peg or stud cast upon or otherwise fixed
to the latch. The camlever on being pulled by the forefinger of the operative lifts
the latch and liberates the cradle which is held up at the same time by the operative
pressing the thumb against the thumb lever. By moving the thumb backwards or
opening the hand the bobbin can be let down gently upon the drum so that the
bobbin starts slowly to rotate and gradually gains speed and does not jerk the yarn
so as to break it.
On the sheet of drawings appended hereunto
Figure 1 shows a cross section along line A B of Fig. 3, of the upper part of a

page_text: drum winding frame with my improvement and with the parts in the positions they
occupy while the winding proceeds;
Figure 2 a similar section with the parts in the positions they occupy when the
latch is lifted for lowering the bobbin upon the drum;
Figure 3 a plan of one drum and two bobbin cradles with latches and cam
levers.
The bobbins a,a¹ have loose pegs or skewers, 6 put through them which are
held in grooves of the bobbin cradles or carriers c¹, the bobbins resting while
winding on the drum and being rotated by contact with the same. Catches e e¹
are attached to or formed on the crossbars of the cradles e e¹ which are mounted on
the rods ff, and latches g g are strung upon these rods as shewn, the latch on one
rod resting on the top of the other while the winding proceeds, these arrangements
being of the usual kind. My improvement consists in. the addition of.thumb
levers m m¹ fixed to or formed on the cross-bars of the bobbin cradles e c' and of
cam levers hh-one of which is shewn separately on the right of Figure 1,-
mounted upon the rods ff which camlevers seize under pegs i formed on.or.fixed
to the sides of the latches gg. Slots may be formed in the camlevers.h has shewn
on the drawings into which the pegs enter, the upper part of which slots holds. the
levers in their positions when the latches are down and prevents. them: from falling
back too far. Set-hoops n n' hold the. latches.and cam levers in their places. upon
the rods ff.
When the bobbin cradle is to be lowered, the operative seizes. the thumblever
and cam lever between the thumb and forefinger and by drawing them together
brings the parts into the positions shewn on the left hand of Fig. 2, when the tail o
of the catch e comes against the rod and stops further movement. Keeping, the
lever pulled forward, whereby the hand is steadied, the bobbin a can be let down
gently upon the drum d by moving the thumb backwards or farther away from the
forefinger so that the bobbin can slip at first and its rotation be started slowly
before the thumb is taken from the lever m and the full weight of the bobbin and
cradle allowed to come upon the drum. When the forefinger is removed from the
cam lever, this lever and the latch g drop back into. their original positions shewn
on Figure 1.
ii
Obviously the pegs may be fixed to or formed on the levers h h and the
latches g g formed with grooves or slots for them to work in instead of the reverse
arrangement herein before described. The cam levers may be hinged on pegs or
studs in brackets fixed to one of the machine rails instead of on the rods ff and
the shapes and arrangement of the parts varied to suit different. constructions of
drum winding frames to which my improvement is to be applied.
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
In "latch and catch" drum winding frames the arrangement of thumb levers
fixed to or formed on the bobbin cradles or carriers and of camlevers, or their
equivalents operating the latches substantially as hereinbefore described and
illustrated by the drawings and for the purpose set forth.
