County of Middlesex, Patent Agent.. "IMPROVEMENTS IN SELF-ACTING APPARATUS

•
This Invention is specially applicable to machines for preparing wool, silk, or
cotton, its object being, first, to clean and clear in a self-acting manner the combs
of the drawing frame of bobbin and other machinery for spinning combed wool,
cotton, or silk; and, secondly, in an automatic stop motion coming into play as soon
as the silvers of material tend to coil round the laminating rollers.
The characteristic features are the employment and combination of a rocking
lever (replacing the usual lever of the cleaning brush of the laminating cylinder) of,-
1st. Two wooden tablets covered with long pile cloth for cleaning the laminating
cylinders.
2nd. A cylindrical metal brush for cleaning the comb.
3rd. A card tablet for cleaning the metal brush.
The rocking lever, movable on its axis, is actuated by another lever which liberates
the disengaging bar for stopping the machine, and is supplied with a counter limiting
the duration of the cleaning. The rocking lever is prolonged beyond its axis for
supporting another axis parallel with the former, and furnished with small groove
pulleys governing the metal brush by means of cotton threads, and causing it to
turn at each removal of the bobbins. This rotation of the brush lasts about three
or four minutes, more or less, and stops of itself by the action of the counter, which
latter is governed by the feed cylinder.

page_text: The counter is established as follows:-An endless screw keyed to the feed roller
governs change wheels mounted on an axis, which axis, by another endless screw,
returns the motion to a toothed wheel whose face is supplied with studs and turns
on the axis of the rocking shaft.
The studded wheel gears or ungears two toothed wheels. At each turn of the
former wheel a lever gears these two latter, and this gearing lasts two or three
minutes, during which time the cleaning takes place.
Another wheel gearing with the studded wheel determines the length of time for
removing the bobbins, and stops the machine by means of the lever actuating the
rocking lever; the removal is then effected.
In cotton preparing machines the rocking lever supports three cleaning rollers
covered with long pile cloth.
Supposing the silver of material winds round one of three rollers, this becoming
increased in diameter causes the lever to rock and the ungearing is effected, as before
described.
