Improvements in Friction Driving Mechanism for Warping,
Balling and other Textile Machines.
We, THOMAS HOLT LIMITED, of Atlas Iron Works, Rochdale, in the County of
Lancaster, and FRANK ASHWORTH HOLT, of the same address, Machine Makers, 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:
Our invention relates to improvements in friction, driving mechanism for warping,.
balling and other textile machines, and the chief object of our invention is to
construct a friction driving clip which can be readily adjusted to slip or yield more or
less as required when in work.
In certain classes of textile machinery as for instance in a warping machine or in
a beaming machine for making ball warps or sections of warps it is necessary that
a certain portion of the machine shall be run at a gradually decreasing or slower
motion throughout the winding of the warp, and in proportion to the increase in the
diameter of the ball warp or section, and to effect this a pair of friction wheels or
dises have usually been employed to give the decreasing speed to the ball or
section.
It is found in practice very difficult to vary the friction between such discs, and
almost impossible to cause them to slip or yield upon one another so smoothly
that a ball warp or section can be wound of an uniform tension throughout.
We accomplish this by the mechanism illustrated on the accompanying sheet of
drawings in which-
Fig. 1 is a sectional side elevation, and Fig. 2 a front elevation partly in section of
a friction driving clip made according to our invention.
In the drawings,-a designates a shaft upon which is mounted a pair of loose
pulleys b c driven by a strap, not shown; secured upon the shaft is a friction disc d,
the periphery of which is provided with two shallow flanges, between which is fitted
a friction ring e formed in two parts and connected together by bolts f which pass
through lugs on the ring e and through rubber spring buffers g or their equivalents,
and springs h upon which wing nuts i bear.
It will be noticed that there are two recesses made opposite one another in the
friction ring and in one recess is fitted the end of a cranked bar which is bolted to
the pulley b, so that when the driving strap is on this pulley motion will be
communicated through the bar i and friction ring e to the disc d and through it to
the shaft a upon which the disc d is secured.
When the resistance of the machine increases say by the gradually increasing
diameter of the warp beam, ball or section, the ring e slips on the disc d and the
speed of the shaft a and machine are smoothly and evenly reduced.
The driving power of the disc d can be adjusted and varied by tightening or
slackening the wing nuts i as required.
We wish it to be understood that we do not limit the application of our improved
friction driving clip to a warping or beaming machine, as it inay be employed in any
class of textile machinery to which its special features are applicable.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination of a driving disc and a friction ring made in two parts
joined together by spring bolts or their equivalents and connected in any convenient
manner to a pulley mounted loosely on the same shaft as the driving disc
substantially as and for the purposes herein described.
2. In combination a friction disc fast on the driving shaft of a warping or other
textile machine, a driven pulley loose on the shaft, a divided ring embracing the
friction disc, springs and adjustable screws for regulating the grip of the ring on the
friction disc, means for driving the ring and friction disc from the pulley all
substantially as and for the purposes herein set forth.
