I, JAMES ROBERTSHAW of 3 & 5, Simpson Street, Angel Street Manchester in
the County of Lancaster, Machinist, do hereby declare the nature of this Invention
to be as follows:-
1
It consists in certain improvements, in machinery manufactured under Patents
No 375/79 and 4477/79 (transferred to me by two assignments dated the 7th of
May 1880 and the 3rd of November 1882 respectively) and Patents N° 841/81,
499/82 and 3746/82 granted to myself and another. Whereby the frame bearing
the fallers or rollers carrying the hanks is raised without weights, the fallers are
kept revolving while the frame is being raised, the frame is automatically checked
when it has reached either its proper height or depth, and the wringing can be
accomplished with greater readiness. To accomplish this I attach to the back of
the vat by suitable bearings and connections a short perpendicular shaft, on the
upper end of which I key a bevel pinion, in which two bevel pinions, attached to
a sliding shaft revolving horizontally along the back of the vat, work, and are
brought into action as the frame is required to rise or fall by means of a suitable
lever under the control of the user, which slides the shaft to right or left. To the
lower end of the perpendicular shaft I fix a spur wheel which actuates another
spur wheel attached to the lower end of a long screw which is fixed in a perpen-
dicular position and parallel to the upright shaft. This long screw works in a
thread cut inside a tube attached beneath the frame bearing the fallers. On the
bevel pinion wheels being brought together the screw is revolved and so raises or
lowers the frame. To keep the fallers in motion while the frame is being raised
I pivot a frame of metal, fitted with suitable bearings by one end to the side shaft
of the vat and by the other to the faller frame. Inside this frame are two or
more spurwheels working in each other and so adjusted as to always bite against
both the spurwheels on the faller frame and the spurwheel upon the driving shaft.
Attached to the frame that carries the fallers is a horizontal rod which carries
wo catches or projections one of which stops the motion as soon as the frame has

in the vat. This is accomplished by a lever, pivoted between the rod and the
sliding shaft, one end of which rests in a slot cut in one of the pinion wheels, or in
the shaft, and the other is pressed or drawn by the catches and so slides the shaft
to the right or left and automatically connects or disconnects the pinion bevel
wheels. In order to give great convenience to the wringing motion I actuate_it_by_
means of an ordinary he and she motion controlled as before by the foot lever
instead of the cumbersome methods now in use.

I, JAMES ROBERTSHAW of 3 & 5 Simpson St. Angel St. 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
ascertained in and by the following statement:-
It consists in certain improvements, machinery manufactured under Patents
No. 375/79 and 4477/79 (transferred to me by two assignments dated the 7th of
May 1880 and the 3rd of November 1882 respectively) and Patents No 841/81,
499/82 and 3746/82 granted to myself and another; whereby the frame bearing
the fallers or rollers carrying the hanks is raised without weights, the fallers are
kept revolving while the frame is being raised, the frame is automatically checked
when it has reached either its proper height or depth, and the wringing can be
accomplished with greater readiness. To accomplish this, I attach to the back of
the vat by suitable bearings and connections a short perpendicular shaft, on the
upper end of which I key a bevel pinion, in which two bevel pinions, attached to
a sliding shaft (or sliding upon a fixed shaft) revolving horizontally along the back
of the vat, work, and are brought into action as the frame is required to rise or fall
by means of a suitable lever under the control of the user, which slides the shaft
or the bevel cogs as the case may be to right or left. To the lower end of the
perpendicular shaft, I fix a spur wheel which actuates another spur wheel attached
to the lower end of a long screw which is fixed in a perpendicular position and
parallel to the upright shaft. This long screw works in a thread cut inside a tube
or nut attached beneath the frame bearing the fallers. On the bevel pinion wheels
being brought together the screw is revolved and so raises or lowers the frame.
To keep the fallers in motion while the frame is being raised I pivot a frame of
metal, fitted with suitable bearings, by one end, to the side shaft of the vat or to a
suitable bracket on the vat and by the other to the faller frame. Inside this frame
are two or more spur wheel working in each other and so adjusted as to always.
bite against both the spur wheels on the faller frame and the spur wheel upon the
driving shaft. Attached to the faller frame is a perpendicular rod which carries
two catches or projections, one of which stops the motion as soon as the frame has
arrived at its full height, and the other when it has descended to the proper level
in the vat. This is accomplished by means of a lever, pivoted between the rod
and the sliding shaft, one end of which rests in a slot cut in one of the pinion
wheels, or in the shaft, and is pressed or drawn by the catches, and so slides the
shaft, (or pinion wheels as the case may be) to the right or left and automatically
connects or disconnects the bevel pinion wheels. In order to give greater con-
venience to the wringing motion, I actuate it by means of an ordinary he and she
motion, adapted in the following manner :-
I attach to the back of the wringing hook a wheel or disc with an edge of a
suitable slope or bevel. This when the wringing motion is required is brought
into contact with another disc or wheel formed with a cavity the inside edges of

page_text: which are formed with a slope or bevel to correspond with the bevel of the he disc.
They are brought together by means of a treadle which slides the she disc upon its
shaft over the he disc until the bevel edges grip upon each other and so revolve
the wringing hook, with a greater or less force according to the pressure on the
treadle. They are automatically parted by means of a counterpoise weight upon
the back of the treadle or any other suitable position or a spring The she disc
-receives its motion from the driving shaft by means of suitable bevel spurwheels.
In order that the foregoing may be better understood, I send herewith a shect of
Drawings in which is shown a back view of the apparatus a indicating the upright
shaft. Actuated from the shaft b by the bevel pinion wheels cc which work in
the pinion wheel d according to the side motion given by the lever e under the
control of the user, findicates the upright screw actuated from the upright shaft a
by means of the spur wheels g and h, and working in the tube or nut i and so
raising or lowering the fallen frame k.
.
Z indicates the metal frame carrying spur wheels m and n which keep the fallers
in motion.
The perpendicular rod o attached to the faller frame k stops the frame at its
proper height and depth by means of the projections p and r respectively which
press upon the projections on the lever e and so put the pinion wheels auto-
matically in or out of gear. I also can reverse the motion of the fallers by means
of pinion wheels t and u which are put in' or out of gear by the lever v.
"
Having now. particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1st The apparatus, substantially as described and shown herein before and in the
accompanying drawing, for the purpose set-fortli.
2nd An upright screw for raising and lowering a fallen frame, substantially as
described and shown, herein before and in the accompanying drawing, for the purpose
set-forth.
3rd A metal frame, with spur wheels for keeping the fallers in motion, while

the accompanying Drawing for the purpose set-forth.
4th A rod with projections to automatically stop the rise and fall of a faller
frame, substantially as described and shown herein before and in the accompanying
Drawing for the purpose set-forth.
