Improvements in Candroys or Machines for Winding Woven Fabrics
upon Boards.
I, CHARLES HILL, of Saint James Road Works, Forfar, in the County of
Forfar, North Britain, Cashier, do hereby declare the nature of this invention to
be as follows, that is to say :-
My said invention has for its object to improve the construction of certain parts
of candroys or machines for winding woven fabrics upon boards, and to render such
machines more convenient and satisfactory in operation than as hitherto made.
In a machine of the kind to which my invention is applicable the board upon
which the woven fabric is to be wound is held between, and by cross heads or
chucks fixed upon two shafts which are in the same horizontal line and carried in
headstocks or frames at the opposite sides of the machine. The crossheads are
grooved to receive the ends of the board, and according to my invention the
bottoms of the grooves consist of movable pieces which are perforated to allow
pins to pass through them, these pins being fixed to back parts of the crossheads..
When the board is in position between the crossheads they pass through the
movable bottom pieces and grip the board at the ends, so as to keep it fixed ready
for winding on the cloth. Each crosshead moves inwards and outwards with its
shaft, and a helical or other spring applied between the crossbead and a part which
moves on the shaft and to which the movable bottom piece is attached, and when
the crossheads are pressed. towards each other to grip the board, the springs cause
the pin points to project through the holes in the movable bottom into the ends of the
board. The movable bottom serves to guard the points of the pins while inserting
the board, thereby facilitating that operation and also to eject the board with the
cloth from the crosshead grooves when the winding is completed, the pins being
withdrawn along with the crossheads by the action of the foot lever afterwards
described. The shafts are moved towards or from each other by means of grooved.
collars on them acted on by forked levers; and the levers at the opposite sides of
the machine are connected by levers and liuks or rods so as to move simultaneously in.
opposite directions, one hand lever, preferably at the right-hand side, being
arranged in connection with a catch plate for holding it in its different positions.
The winding operation is performed in the ordinary way; and when a piece of
fabric has been wound upon a board, the crossheads or chucks which hold and turn
the board are withdrawn by the action of a foot lever or treadle which is arranged.
in connection with the hereinbefore described parts for moving the two shafts and
crossheads inwards and outwards. With the foot and hand levers arranged as and
for the purpose described, the operator has both hands free, for inserting
and adjusting an empty board and also for removing the wound piece of fabric;
and he can very conveniently effect the removal even if the piece is of considerable
weight.
To suit different lengths of board or widths of fabric one of the headstocks may.
be in the form of a movable bracket or frame capable of being secured in different
positions. The rod or link connecting the levers at opposite sides of the
machine will require to be capable of alteration to correspond with the altered
headstock.

upon Boards.
I, CHARLES HILL, of Saint James Road Works, Forfar, in the County of
Forfar, North Britain, Cashier, 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, that is to say :-
My said invention has for its object to improve the construction of certain parts
of candroys or machines for winding woven fabrics upon boards, and to render such
machines more convenient and satisfactory in operation than as hitherto made.
In a machine of the kind to which my invention is applicable the board upon
which the woven fabric is to be wound is held between and by crossheads or chucks
fixed upon two shafts which are in the same horizontal line, and carried in
headstocks or frames at the opposite ends of the machine. By my invention the
construction of the crossheads and of parts connected therewith is improved, and a
machine as made with the improvements is shown on two accompanying sheets of
explanatory drawings and is hereinafter described.
Figure, 1, on Sheet, 1, of the drawings is an end elevation of the machine;
and
Figure, 2, on Sheet, 1, and Figure, 3, on Sheet, 2, are parts of a front elevation
showing the ends of the machine, the length of which may vary in different cases to
suit the widths of fabric to be wound.
Figures, 4, and 5, are enlarged views of a crosshead or chuck.
the same reference letters and numerals are used to mark the
wherever they are repeated.
In these drawings
same or like parts
At the right-hand end of the machine (Figure, 3) and supported by two
transverse frame standards, A, there is a set of stepped pulleys, B, to receive
a driving belt, these pulleys being loose on a tubular shaft on a shaft, C, with which
they can be engaged by means of a frictional cone clutch, B 1, which is movable by
a lever, B 2, connected to a lever, B3, on a shaft, B 4, having fast on it a foot
lever, B 5. At the other end of the machine (Figures, 1, and 2) a shaft, D, in the
same line as the shaft, C, is carried in a headstock or frame, E, which is adjustable
upon the main framing from or towards the end of the machine. The shafts, C, D,
are movable end ways in their bearings, the parts for moving them being arranged
to move them simultaneously towards or from each other. A lever, F, acting on a
grooved collar, C 1, on the shaft, C, is connected by a rod, F 1, to a two-armed
lever, F 2, at the other end of the machine, and the lever, F 2, is connected to a
lever, F 3, which acts on a grooved collar, D 1, on the shaft, D. The levers, F 2, F 3,
are connected by a link, F4, of a length admitting of its being jointed to the
lever, F3, suitably, for various positions of the adjustable headstock or frame, E.
The lever, F 3, is on a shaft F 5, which has fast ou it a hand lever, F 6, it having
been found most convenient to arrange this hand lever at the left-hand end of the
machine. The lower lever, F2, also, is on a shaft, F7, which has fast on its front
end a foot lever, G; and a similar foot lever, B5, is at the other end of the
machine fixed on the shaft, B 4, connected with the clutch, B 1.
On the inner end of each shaft, C, D, there is a crosshead or chuck, which
is shown enlarged in Figures, 4, and 5, on Sheet, 2, Figure, 4, being a vertical
section, and Figure, 5, a horizontal section as at the line a-a, in Figure, 4.
On the end of the shaft there is formed or fixed a crosshead, J, having formed or
fixed on its side cheeks, J 1, the horizontally projecting parts of these cheeks
forming a groove in which the board, K, on which the fabric is to be wound is held.
The bottom of the groove is formed by a part, L, of a rectangular frame, L 1, made

page_text: with a boss, L 2, fitted to slide on the shaft C (or D) and a helical spring is applied
between the boss, L 2, and the crosshead, J. The part, L, has holes in it through
which can project pointed pins, J 2, fixed in the crosshead, J, and when a board, K,
has been placed in the grooves of the crossheads, the pins, J 2, being then
withdrawn so as not to be injured by or obstruct the entering of the board, the
shafts, C, D, are by means of the hand lever, F 6, moved towards each other to
grip the board the pins, J 2, then projecting through the part, L, and fixing the
board. On the shafts, C, D, being withdrawn to release a board on which fabric
has been wound, the movement of the parts, L, to cover the pins, J 2, is insured by
blade springs, L 3, fixed to the framing and encountered by the bosses, L 2. The
woven fabric which is indicated by a double dotted line in Figure, 1, is, as usual
drawn in a tortuous course round square wooden smoothing bars, M.
With the foot and hand levers arranged as and for the purpose described, the
operator can insert and adjust an empty board, and has both hands free for
removing the wound piece of fabric; and he can very conveniently effect the
removal even if the piece is of considerable weight.
When for any reason it may be desirable to wind the fabric on "spits" as is
done in some ordinary candroys, the crossheads or chucks with their parts, J, L,
can be easily removed from the shafts, C, D, and the ordinary parts substituted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
1. The combination of parts constituting the improved candroy, substantially as
hereinbefore described and shown in the accompanying drawings.
2. In a candroy the combination of two shafts movable towards and from each
other by connected levers acted on by a foot lever, with crossheads or chucks for
holding a board for winding on a woven fabric, constructed and operating
substantially as and for the purposes hereinbefore described.
