AN IMPROVED METHOD OF DRIVING THE SPINDLES OF SPINNING AND DOUBLING MACHINES
Year: 1885

Doubling Machines.
I JOHN ELCE, of 9 Hopwood Avenue, Manchester, Lancashire, Machine Maker,
do hereby declare the nature of said Invention for AN IMPROVED METHOD OF
DRIVING THE SPINDLES OF SPINNING AND DOUBLING MACHINES, to be as follows:-
The object of my Invention is to improve upon the well known method of
"tape driving" which has been long in use for throstle and doubling frames. The
chief objection to this system of driving is that as four spindles are driven by
a single tape the grip of the tape on the wharves is not sufficient to impart a
regular uniform speed to the spindles.
In carrying my Invention into effect I employ one tin roller and a single round
band to drive two spindles, the band passing preferably from the tin roller to the
farther spindle, then across the frame to the other spindle, back over an adjustable
grooved tension pulley and finally completing its circuit by returning from thence
to the tin roller. I employ an adjustable grooved tension pulley for each band and
pair of spindles and I mount each pulley in suitable bearings in a swivel bracket
which is weighted at one end in the ordinary or any convenient manner in order to
take up slack in the band.
By my improved method of driving each band embraces one half of each spindle
wharf instead of only one quarter as in the tape driving system-and the extra
grip and driving power thus obtained insure uniformity in the speed of the spindles
and a perfect twist on the yarn or thread.

An Improved Method of Driving the Spindles of Spinning and
Doubling Machines.
I JOHN ELCE, of 9 Hopwood Avenue, Manchester, Lancashire, Machine Maker,
do hereby declare the nature of said Invention for AN IMPROVED METHOD OF
DRIVING THE SPINDLES OF SPINNING AND DOUBLING MACHINES, 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 Invention is to improve upon the well-known method of
tape driving" which has been long in use for throstle and doubling frames. The
chief objection to this system of driving is that as four spindles are driven by
a single tape, the grip of the tape on the wharves is not sufficient to impart a
regular and uniform speed to the spindles.
In carrying my Invention into effect I employ one tin roller and a single round"
band to drive two spindles, one on either side of the frame; I employ an adjustable
grooved tension pulley for each band and pair of spindles and I mount each pulley
in suitable bearings in a swivel bracket which is weighted at one end in the
ordinary or any convenient manner in order to take up the slack in the band.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being had
to the figures and letters marked thereon.
Figure 1 is a plan and Fig. 2 an elevation of so much of a spinning or doubling
frame as is necessary to illustrate my Invention.
a is the tin roller preferably placed out of the centre of the frame as shown;
ba round driving band; c c¹ a pair of spindles and wharves; d a grooved tension
pulley supported in bearings e¹ in one arm of the bracket e which is mounted and
free to swivel on the shaft f and is weighted by the adjustable weight g.
The tin roller a is rotated in the direction indicated by the arrow, Fig. 2, the
band 6 passing from the tin roller a to the grooved tension pulley d then to the
spindle wharf c, then across the frame to the spindle wharf c¹ and finally completing
its circuit by returning from thence to the tin roller a. The amount of tension on
the band b can be regulated by adjusting the position of the weight g on the arm
of the bracket e, or the tension on the band b may be regulated by the application
of springs if preferred.
By my improved method of driving I am able to employ long driving bands as
in the tape system of driving and yet as each band drives only two spindles the
band embraces one half of each spindle wharf as in the double tin roller system of
driving. I thus obtain all the advantages of both systems of driving without any
of the well known defects of either.
My invention can be readily applied to existing spinning or doubling frames.

page_text: 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
1. In a spinning or doubling frame, driving each pair of spindles, one spindle
on either side of the frame from one tin roller by means of a single round band, the
said band passing over an adjustable tension pulley, substantially in the manner
and for the purposes herein set forth.
2. The combination of the tin roller a, band b, spindle wharves c c and the
adjustable tension pulley d, or its equivalent, all substantially as and for the
purposes herein described and as illustrated by the Drawings annexed.
Dalty is for day of November food.
