COMPLETE SPECIFICATION.
Oertain Improvements in Driving Mechanism for Spinning and
Doubling Frames.
I WILLIAM TAYLOR of 19 Hill Street Oldham in the County of Lancaster
Engineer 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
My present invention relates to the invention for which Letters Patent numbered 2265
were granted to me on the 14th February 1887 and consists in certain further
improvements upon or alternative arrangements of the driving mechanism set forth
in the Specification to my said Letters Patent.
In addition to the objects mentioned in my said Specification I have for ny
present invention a further object namely to adapt my arrangement of driving
mechanism for use in rooms with low ceilings and in other places where it would be
difficult or impossible to have a counter-shaft supported in brackets above the top of
the end frames as shown and described in my said Specification.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an end view and Fig. 2 part of a side view of a spinning or doubling
frame with two tin rollers to which my present improvements are applied.
In these views a designates the ordinary end framing of the machine and bare
respectively the shafts of the two tin rollers for driving the spindles (not shown). On
the shaft is mounted a pair of loose pulleys c c and on the boss c² of the pulley c
is fixed a double grooved pulley d; a second and smaller double grooved pulley e is
keyed to the shaft 6 and a double grooved pulley is also keyed upon the
shaft b¹.
In brackets secured on the top of the end framing are mounted a four grooved
pulley and a two grooved pulley h the latter being supported in bearings which are
adjustable by means of the screw i.
The course of the endless band or rope j is as follows:-Starting from the joint X
Fig. 1 the rope is first taken round under the double grooved pulley d on the tin

page_text: roller shaft thence up and over the double grooved pulley 1 then down under the
double grooved pulley f up and again over the pulley h returning to the second
groove of the pulley thence up over the four grooved pulley g down to the two
grooved pulley e up and again over the pulley 9 returning to the second groove of the
pulley e again up and over the third groove of the pulley g thence down to the second
groove of the pulley d up and back over the fourth groove of the pulley g
completing the round at the joint X where the ends of the band or rope jare pieced
together.
From the foregoing description it will be readily understood that when the driving
belt is on the pulley c¹ motion will be given to the grooved pulley d and transmitted
by the endless band or ropej and grooved pulleys to the shafts by which means
both the tin rollers thereon are driven at a uniformn speed by one endless band or rope
the tension on which can be readily regulated by turning the screw i and adjusting
the position of the pulley h.
The same changes of speed obtained by the use of the countershaft as described in
my aforesaid Specification can now be obtained and in a similar way by simply
altering the size of the rope driving pulley d.
My present improvements may be applied to frames having only a single tin
roller substantially in the manner described in my said Specification.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. Driving the tin rollers (or tin roller) of a spinning or doubling frame by means
of an endless band or rope from a grooved pulley fixed on the boss of a driven pulley
mounted loose on one of the tin roller shafts substantially as herein described and as
illustrated by the Drawings annexed.
2. The combined arrangement of parts embodying my present improvements in
driving mechanism for spinning and doubling frames substantially as herein shown
and described.
