PROVISIONAL SPECIFICATION.
Improvements in Driving the Spindles of Spinning and Doubling
Frames.
I, PHILIPPE BAZIN, 'of Condé-sur-Noireau, France, Spinner, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in driving the spindles of spinning and
doubling frames and the chief object of my invention is to drive the spindles with
greater regularity and to reduce the wear on the driving bands.
In carrying my improvements into effect I employ two thin rollers one of which
is driven positively and the other by the friction of the bands which pass from
the driven tin roller to the spindle wharves on one side of the frame; but
instead of employing single driving bands and spindle wharves with single grooves,
I employ double driving bands and spindle wharves with two grooves. Each driving
band passes from the under side of one tin roller up over the second tin roller and
round the first groove in its spindle wharve then back round the first tin roller
and up over the second tin roller to the second groove in the spindle wharve and
completes the circuit by returning back round the first tin roller.
Instead of employing double bands I might employ two separate bands for each
spindle wharve and I might employ more than two grooves if found desirable.
By the use of my invention the driving bands need not be so tight as in the
ordinary arrangements, consequently there is less strain and wear upon the bands,
while the spindles are driven at a more uniform speed.

COMPLETE SPECIFICATION.
Improvements in Driving the Spindles of Spinning and Doubling
Frames.
I, PHILIPPE BAZIN, of Condé-sur-Noireau, France, Spinner, 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 invention relates to improvements in driving the spindles of spinning and
doubling frames and the chief object of my invention is to drive the spindles with
greater regularity and to reduce the wear on the driving bands.
In carrying my improvements into effect I employ two tin rollers one of which
is driven positively and the other by the friction of the bands which pass from the
driven tin roller to the spindle wharves on one side of the frame; but instead of
employing single driving bands and spindle wharves with single grooves, I employ
double driving bands and spindle wharves with two grooves. Each driving band
passes from the under side of one tin roller up over the second tin roller and round
the first groove in its spindle wharve then back round the first tin roller and up over
the second tin roller to the second groove in the spindle wharve and completes the

page_text: E
circuit by returning back round the first tin roller. Instead of employing double
bands I might employ two separate bands for each spindle wharve and I might
employ more than two grooves if found desirable.
By the use of my invention the driving bands need not be so tight as in the
ordinary arrangements, consequently there is less strain and wear upon the bands,
while the spindles are driven at a more uniform speed.
The accompanying drawing is a perspective end view of part of a spinning or
doubling frame to which my improvements are applied.
I have shown the arrangement which I prefer to employ for driving the spindles.
Bis a tin drum mounted upon a driven shaft for driving all the spindles E upon one,
in this case, the left hand side of the frame, on each spindle E is secured a wharve
with two grooves A and D to receive an endless band F which passes twice
round the tin drum B and twice over a tin drum C and round the two grooves A
and D in the wharve on the spindle E.
The course of the endless band F can be readily traced from the drawing where it
passes from the upper groove A in the wharve on the spindle E direct to the top of
the tin drum B round it and up over the tin drum C to the lower groove D in the
wharve round which it passes back over and round the tin drum B and up over the
tin drum C from which it passes to the upper groove A in the spindle wharve thus
completing the double circuit.
In order to drive each spindle E' on the right hand side of the machine an endless
band, not shown, passes twice round the tin drum C, twice over the tin drum B and
then round two grooves A' D' in the spindle wharve on the spindle E' in a manner
already described in reference to the spindles E.
It is evident that in place of one band F, two bands, one for the upper groove A
or A and another for the lower groove D or D¹ might be employed to drive each
spindle.
The advantages of forming a spindle wharve with two or more grooves with an
endless band or bands passing over each groove for driving the spindles are as
follows:-
a. For the same tension on the spindle bands the adhesion upon the spindle
wharves and upon the tin drums will be in proportion to the number of grooves,
with the result that there is less slip even when the spindle bands are slack and
consequently the spindles are driven at a more uniform speed.
b. The bands being under less tension, stretch less, wear less and last longer.
c. The tin drum C which is driven solely by the friction of the spindle bands,
being actuated by a number of spindle bands proportioned to the number of grooves
in the wharves, receives a constant speed which corresponds exactly with that of the
driven drum B, consequently the spindles E' are driven the same uniform speed as
the spindles E.
d. In the ordinary driving a spindle is stopped when a band breaks or comes out
of its spindle wharve, whereas in my improved arrangement a band rarely breaks
because the strain and wear upon it is considerably less than when a single grooved
wharve is employed.
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. The method of driving the spindles of spinning and doubling frames by means
of spindle wharves each having two or more grooves and spindle bands each passing
as many times over two tin drums as there are grooves in each wharve substantially
as herein set forth.
2. The combination with a spindle wharve having two or more grooves, of a
separate spindle band for each groove each band passing over and round two tip
drums substantially as herein set forth.
3. The combination with the spindles E or E¹ and spindle wharves having two

page_text: or more grooves, of the endless bands F and tin drums B and C all arranged and
operating substantially as and for the purposes herein described and as illustrated.
by the accompanying drawing.
