PROVISIONAL SPECIFICATION left by John Billington Booth and James
Beckett at the Office of the Commissioners of Patents, with their Petition,
on the 8th February 1856.
We, JOHN BILLINGTON BOOTH, Spindle Manufacturer, and JAMES BECKETT,
Overlooker, both of Preston, in the County of Lancaster, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR PRE-
PARING AND SPINNING COTTON, WOOL, & OTHER FIBROUS MATERIALS," to be as
follows:-
The first part of our Invention refers to preparing machines of the character
of the roving or slubbing frame, and relates to arrangements of mechanism for
diminishing or increasing the speed of the bobbins as they enlarge in diameter
by the material wound upon them. This has hitherto been effected by the
friction of revolving cones. or discs acting directly or in connection with that
combination of wheelwork known as the "differential geering." Now, this
part of our Invention consists in the use, for this purpose of reciprocating
movements, which are imparted to a lever that operates on a click or pawl, or

page_text: a series of clicks or pawls, to cause them to revolve two ratchet wheels, one of
them by the movement of the lever in one direction, the other by the move-
inent of the lever in the opposite direction, the two ratchet wheels being
geered together by a bevil wheel placed between them, that geers with bevils
attached to the ratchet wheels, and the motion given to the first-mentioned
bevil wheel by those in "connection with the ratchets is conveyed from it to the
central wheel of the differential geering. The revolving speed of the ratchets
is gradually increased or decreased, as may be required, by causing the
reciprocating movement which operates on the lever propelling the ratchet
wheels to act gradually nearer or further from its fulerum, and by this means
produce the increase or decrease in the revolving speed of the bobbins. The
reciprocating movements which act on the lever are produced by a crank or
excentric, and the changes in the position of the point of connection of the
. lever with the reciprocating movement may be produced by the same or
similar mechanism to that employed for producing the changes in the position
of the belt when cones are employed.
The second part of our Invention relates to machines for spinning. Our
combination of machinery for this purpose acts in the same manner as the
'self-acting mule, except that the carriage or frame containing the 'spindles does
not move; other arrangements being employed for accomplishing the purpose
for which the carriage moves, namely, a bar or rod having a reciprocating move-
ment given to it which takes with it the thread as delivered by the rollers, and
when the length of a stretch is spun, allows it to be wound on to the spindle
or cop.
With these exceptions, our new combination of machinery acts in the same
manner as the ordinary self-acting" müle; suitable modifications being made in
the geering and actuating mechanism to adapt it. to our new arrangements.
We may, however, further explain, that in our new combination of spinning
machinery the drawing rollers will have to deliver during the time of spinning,
and cease to deliver during the winding on of the thread spun. The recipro-
cating movements of the bar or rod to take, up the thread as it is spun and
delivered by the rollers may be accomplished by, the same or similar, combina
tions of mechanism to those einployed for giving motion to, the carriage of the
ordinary múle. The backing off (if required) may be also accomplished by
the same or similar mechanism to that hitherto employed. The fallers may
also be arranged and brought down in the same manner, as in ordinary,mules,
and they may be actuated to build the cop by a revolving cone shaper," or
by other suitable mechanism. The cone shaper or other mechanism may be

actuating it. The winding on may be accomplished by similar arrangements
of mechanism to that now employed, actuated from the movements of the
reciprocating bar or rod, or the mechanism giving motion to it.
And, lastly, the changes in the working of the parts which are produced by
the carriage of ordinary mules may be effected from the movements of the
reciprocating bar or rod or mechanism actuating it.
