IMPROVEMENTS IN WINDING DRUMS
Year: 1884

page_text: I GEORGE HEATON DAGLISH of St Helens Engine Machine Boiler and Bridge
Works St Helens, in the County of Lancaster Engineer do hereby declare the
nature of my said invention for "IMPROVEMENTS IN WINDING DRUMS" to be as
follows:-
The object of my present invention is to so construct winding drums for mines
and other purposes both those of the external and internal class that the grooves
for the ropes are disposed at equal distances, that there is greater lateral clearance
for the ropes and more numerous coils on same width of drum face. Greater
strength and enhanced durability are advantages secured.
The invention consists essentially in forming the surface on which the grooves
are of curved outline.
In carrying my invention into practice I secure the framework to the shaft in
any usual way and clothe the winding face with sheet iron or other material so
that when rivetted up or finished the clothing remains in curved form viewing it
from its greater to its lesser diameter. The grooves for the rope are in spiral lines
on the faces. When a double faced drum is used there is usually a, winding space
on the cylindrical periphery. The arms of the drum whether single or double-faced
are held in position by diagonal stay pieces securely attached thereto to take
lateral strains and are held in position by means of channelled or grooved pieces
for radial strains.

I GEORGE HEATON DAGLISH of St Helens Engine Machine Boiler and Bridge
Works St Helens in the County of Lancaster, Engineer, do hereby declare the
nature of the said invention for IMPROVEMENTS IN WINDING DRUMS, 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 my present invention is to so construct winding drums for mines
and other purposes both those of the external and internal class that the grooves
for the ropes are disposed at equal distances, that there is greater lateral clearance
for the ropes and more numerous coils on the same width of drum face. Greater
strength and enhanced durability are advantages secured.
The invention consists essentially in forming the surface on which the grooves
are of curved outline.
In carrying my invention into practice I secure the frame work to the shaft in
any usual way and clothe the winding face with sheet iron or other material so
that when rivetted up or finished the clothing remains in curved form viewing it
from its greater to its lesser diameter. The grooves for the rope are in spiral lines
on the faces. When a double faced drum is used there is usually a winding space
on the cylindrical periphery. The arms of the drum whether single or doublefaced
are held in position by diagonal stay pieces securely attached thereto to take
lateral strains and are held in position by means of the channelled or grooved
pieces for radial strains.

DESCRIPTION OF THE DRAWINGS.
Fig 1 is a section, and fig 2 an elevation of part of an external faced winding
drum constructed in accordance with my invention, a driving shaft, b bosses
secured thereto c arms secured to the bosses b by rivets or in any usual manner,
d diagonal stay pieces for holding the arms in lateral position, e channelled or
grooved pieces coiled round and secured to the arms so as to serve as carriers for
the rope and retain the said arms in position radially, periphery of drum, g sheet
metal clothing curved face of drum.
Fig 3 is a sectional view of an internal drum here three sets of arms c are used
and the drum has a double periphery ƒ f' and the curved faces h meet at the
centre.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First. Winding drums constructed as herein specified for the purposes setforth.
Second. Winding drums with curved winding surfaces substantially as setforth.
Third. Winding drums with stay pieces for taking lateral and radial strains
substantially as setforth.
