IMPROVEMENTS IN APPARATUS FOR COILING WIRE ROPE ON DRUMS USED FOR STEAM PLOUGHING AND OTHER MACHINERY
Year: 1876

page_text: LETTERS PATENT to Alfred Yeoman Watson, of Norwich, in the County of
Norfolk, for the Invention of "IMPROVEMENTS IN APPARATUS FOR COILING
WIRE ROPE ON DRUMS USED FOR STEAM PLOUGHING AND OTHER MACHINERY,"
Sealed the 15th May 1877, and dated the 28th November 1870.
PROVISIONAL SPECIFICATION left by the said Alfred Yeoman Watson at
the Office of the Commissioners of Patents on the 28th November 1876. .
ALFRED YEOMAN WATSON, of Norwich, in the County of Norfolk. "IMPROVE-
MENTS IN APPARATUS FOR COILING WIRE ROPE ON DRUMS USED FOR STEAM
PLOUGHING AND OTHER MACHINERY."
The object of this Invention is to enable wire rope to coil evenly and with equal
strain on a drum. For this purpose I bolt to the side of the winding drum a worm
or endless screw, which together with the drum revolves freely on a spindle; in this
worm gears a worm wheel formed with slot containing an adjustable crank pin
which works in a slot in a lever having its fulcrum on the frame, and its other
end fitted with a wire rope guide pulley or connected to the frame of such pulley.
The frame which carries the worm wheel and lever hangs loose on the drum spindle.
The guide pulley is thus, when the drum and gear is in motion, swayed back-
ward and forwards, and guides the wire rope accordingly as required.

the said Alfred Yeoman Watson in the Great Seal Patent Office on the

FOR STEAM
The object of this Invention is to enable wire rope to coil evenly and with equal
strain on a drum. For this purpose I bolt to the winding drum a worm or endless
screw, which together with the drum revolves freely on a spindle; in this worm

page_text: gears a worm wheel formed with slot containing an adjustable crank pin which
works in a slot in a lever having its fulcruin on the frame, and its other end fitted
with a wire rope guide pulley, or connected to the frame for such pulley. The
frame which carries the worm wheel and lever hangs loosely on the drum spindle. The
guide pulley is thus, when the drum and gear is in motion, swayed backwards and
forwards, and guides the wire rope accordingly as required.
Figure 1 of the accompanying Drawings is partly a vertical section and partly a
side elevation of a coiling apparatus constructed accoording to my Invention.
Figure 2 is a horizontal section of the same at the line A, B, Figure 1.
An endless screw or worm C is bolted to the lower part of the ordinary horizontal
winding drum D, and the said worin C gears with and actuates a worm wheel E.
This worm wheel carries a crank stud Fadjustable in a slot to the required throw,
and working in a recess formed in the end of the rocking lever G. This lever G
carries guide pulleys H, H, at its other outer end, and is centred upon a stud I.
As will be seen, the greater part of the apparatus is carried by a bracket or frame
K suspended loosely upon the end of the spindle or stud L, which carries the
winding drum D; the bracket K is here shewn double, so as to provide for a
duplex winding arrangement if desired. In operating my Invention the rope to be
coiled on the drum D is led between the guide pulleys H and H', and thence to the
drun, when the mechanism is in motion by the rotation of the drum in the ordinary
manner; the worm wheel E in revolving vibrates the lever G so as to guide the
rope equally and evenly to the periphery of the drum D without regard to the
level of the object, place, or instrument to which the rope is attached.
Having now described the nature of my said Invention, and in what manner the
same may be performed, I declare that I claim, the employment of an adjustable
slotted lever operated by gearing from the winding drum of engine, substantially
in the manner and for the purposes herein-before described, and illustrated by the
accompanying Drawings.
In witness whercof, I, the said Alfred Yeoman Watson, have hereunto set my
hand and seal, this Twenty-third day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
