I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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:-
The object of my invention is to regulate the driving of the taking up bobbins so that
their speed will be proportional at all times to the speed of the spindles. My machine
is constructed on the same pattern as any other mill containing one row of spindles
with the exception that it is greatly narrower being only twelve inches wide instead
of twenty six.
1 have no drum or shive pulley to drive the spindles and instead and in the place
occupied by the drum I have a flat board running all the length of the machine. On
this board are placed a number of pulleys around which passes an endless belt which
is driven from a pulley on the main line of shafting at both edges of the board are
placed at regular distances the spindles of the machine. The endless belt which
passes around the pulleys on the centre of the board also touches the spindles and
drives them; the pulleys acting as rollers to force the belt against the spindles. It
will be seen that if all the pulleys are of the same diamiter they will all receive the
same friction from the belt, and the same will be true of the spindles if they are
properly and exactly set. Consequently the spindles, all running with the same
speed the twisting of the silk will be regular, that is to say, exactly the same for
every spindle. As the belt may get slack and the speed of the pulleys and spindles
be thus reduced I drive the taking up motion of the friction rollers from the last
pulley on the flat board.
Upon the vertical shaft of the last pulley I cut a thread into which a worm wheel
gears, the horizontal shaft of which carries a pulley which drives a belt which passes
around a pulley on the shaft of the friction rollers and drives this shaft and the
rollers. By this arrangement the speed of the taking up bobbins is always pro-
portional to the speed of the spindles.
In the drawings Fig. 1, is a side elevation, partly in section of a spinning mill
embodying my improvements; Fig. 2, a section of Fig. 1 on line 1-2, and Fig. 3,
an end view of the cog wheels on the friction roller shafts.

page_text: A. A' is the frame of the machine. B is the board running from one frame to the
other. P², P. P are the pulleys forcing the belt against the spindles. S, S, S are
the spindles. B³, B', B' are the upright shafts of the pulleys. C is the screw upon
the vertical or upright shaft of last pulley P. Dis the worm wheel working with
screw C. E is an horizontal shaft having at one end the gear wheel D and at the
other the change pulley F. G bearing for shaft E. H bearing for the vertical shaft
B2 of the last pulley P. I is belt passing from change pulley F to pulley J, on
shaft K of friction rollers L. M M. taking up bobbins, N reciprocating rail for laying
the threads evenly on the taking up bobbins. The ordinary device may be used for
reciprocating this rail. R belt for driving pulleys P; this belt is endless and passes
over a driving pulley (not shown) on the main line of shafting. TT are pulleys for
guiding belt R to and from pulleys P.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent I declare that what I claim is
The combination of the endless belt R, pulleys P, Spindles S, pulley P³ with shaft
B and screw C, worm wheel D, shaft E, pulley F, belt I, pulley J shaft K, and
friction rollers L, all substantially.as, and for the purposes, set forth.
