PROVISIONAL SPECIFICATION.
Improvements in Dyeing, Sizing, and Washing Machines.
I, JAMES ROBERTSHAW, of Simpson Street, Rochdale Road, Manchester, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to
be as follows:-
It consists of certain alterations and additions whereby I am enabled to give
automatically to a hank, in process of dyeing in one of my machines an alternative
motion, consisting of any number of turns to the right succeeded by the same
number of turns to the left.
I accomplish this, by fitting upon the driving shaft of the machine a couple of
suitable clutches which are alternately brought into gear or out of gear by means
of suitable levers and slides actuated by suitable pulleys and tooth wheels upon the
machine.

COMPLETE SPECIFICATION.
Improvements in Dyeing, Sizing, and Washing Machines.
I JAMES ROBERTSHAW of Simpson Street Rochdale Road Manchester in the
County of Lancaster Machinist do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
It consists of certain alterations and additions whereby I am enabled to give
automatically to a hank in process of dyeing in one of my machines (Patent
No. 841/81) an alternative motion, consisting of any number of turns to the right
succeeded by the same number of turns to the left.
I accomplish this by fitting upon the driving shaft of the machine a couple of
suitable clutches which are alternately brought into gear and out of gear as
follows:--
Referring to the sheet of drawings sent herewith (which show a back elevation
of one end of my machine with the improved apparatus attached) the fallers a a
which carry the hanks are geared together by the spur wheels bb which are set in
motion by the chain c working against a spur wheel & attached to the end or other
convenient faller.
C
This chain c receives its motion from a spur wheel e keyed upon a short shaft
attached to which is the bevelled spur wheel 6 which receives an alternate motion
from the two bevel pinions ff which are thrown in and out of gear alternately by
the clutch upon the main shaft h. The clutch g is automatically actuated by
means of the lever k pivoted upon a short shaft l'upon which revolves the large
band wheel m which receives its motion by means of the band m 1 from the wheel m 2
keyed upon the upper shaft. This large wheel m is furnished with a long slot n
or a slotted piece of metal n is attached thereto, in which slot n slides a projecting
pin n 1. The effect of this arrangement is, that as the wheel m is slowly revolved
by the band m 1 the projecting pin n 1 comes in contact with the side of the lever
and slides in the slot n until it reaches its further end and then by the continued
motion of the wheel m pushes the lever k and with it the clutch g over assisted by
the weight k 1 thus reversing the motion of the upper shaft when the operation is
repeated from the opposite side.

page_text: By adjusting the size of the wheels m and m 2 and the length of the slot n any
desired number of revolutions may be made before the motion is reversed.
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 :-
The combined apparatus substantially described and shown hereinbefore and
in the accompanying drawings for the purpose set forth.
Dated the 10th day of June 1891..
