IMPROVEMENT IN THE MANUFACTURE OF TIN ROLLERS FOR MULES FOR SPINNING."
Year: 1881

page_text: LETTERS PATENT to William Gledhill, of Mossley, in the County of
Lancaster, for an Invention of "IMPROVEMENT IN THE MANUFACTURE OF
TIN ROLLERS FOR MULES FOR SPINNING."
PROVISIONAL SPECIFICATION left by the said William Gledhill at the
Office of the Commissioners of Patents on the 3rd November 1881.
WILLIAM GLEDHILL, of Mossley, in the County of Lancaster.
"IMPROVEMENT
IN THE MANUFACTURE OF TIN ROLLERS FOR MULES FOR SPINNING."
The object of my Invention is to make tin rollers for mules that will not slip or
turn on their arbors or shafts, and thus prevent "soft yarn" in spinning and the
risk of fire caused by the slipping of the rollers.
I form a slot in the arbor longer at the base than at the opening, and I take a
piece of metal and fit it in the slot, this metal projects above the arbor and forms
a float key. I fit one of these float keys where each roller coupling has to be fixed,
and I make a corresponding slot in the boss of each coupling. I fit set screws in
the boss of the coupling opposite the slot. I solder or fix the tin on two couplings
to form the roller and place one coupling at each end of an arbor; any convenient
number of arbors and couplings may be used, and when the set screws are
When
tightened the rollers are effectually prevented from turning on the arbors.
rollers constructed according to my Invention are used in mules the production of
what is known as soft yarn is entirely avoided and the danger of fire from slipping
rollers is obviated.

"IMPROVEMENT
IN THE MANUFACTURE OF TIN ROLLERS FOR MULES FOR SPINNING."
The object of my Invention is to make tin rollers for mules that will not slip or
turn on their arbors or shafts and thus prevent "soft yarn" in spinning and the
risk of fire caused by the slipping of the rollers.
I form a slot in the arbor longer at the base than at the opening, and I take a

and I make a corresponding slot in the boss of each coupling. I fit set screws in
the boss of the coupling opposite the slot. I solder or fix the tin on two couplings
to form the roller and place one coupling at each end of an arbor; any convenient
number of arbors and couplings may be used, and when the set screws are
tightened the rollers are effectually prevented from turning on the arbors.
"
When rollers constructed according to my Invention are used in mules the
production of what is known as "soft yarn is entirely avoided and the danger of
fire from slipping rollers is obviated.
And in order that my Invention may be fully understood and readily carried
into effect 1 will describe the accompanying Sheet_of_Drawings, reference-being-
had to the figures and letters marked thereon.
Fig. 1 shows an arbor or shaft.
Fig. 2 is a cross section of the coupling.
Fig. 3 is an end view of a coupling fitted on a shaft or arbor.
a is the shaft, b, b, are the float keys which in all cases must be firmly secured
to the shaft; c is the recess which receives the end of the set screw that serves to
secure the coupling on the shaft or arbor, d is the coupling through the boss of
which passes the set screw e, which when tightened secures it on the arbor; f is a
slot inside the boss of the coupling that passes over the float key b.
Having stated the nature of my Invention and described the manner of
performing the same,
I declare that I claim,-
The manufacture of tin rollers for mules for spinning in the improved manner
herein described, that is by fixing in the arbor or shaft a float key or piece of
metal that projects therefrom and enters a slot in the roller coupling secured
thereon as and for the purpose herein specified.
In witness whereof, I, the said William Gledhill, have hereunto set my
hand and seal, this First day of May, One thousand eight hundred
and eighty two.
WILLIAM GLEDHILL. (L.S.)
