PROVISIONAL SPECIFICATION left by the said Samuel Johnson at the
Office of the Commissioners of Patents on the 5th September 1883.
SAMUEL JOHNSON of Rochdale in the County of Lancaster, Manager, "IMPROVE-
MENTS IN MACHINERY USED IN THE PREPARATION OF TEXTILE MATERIALS
"
My Invention relates to the cones and connected parts of machinery used in the
preparation of cotton and fibrous materials for spinning as for example to Slubbing,
Intermediate and Roving frames. In such machines one cone has to be moved
nearer to the other at times in order to slacken the belt. To enable this movement
to be effected I mount the moveable cone in bearings in arms which are fitted to
turn upon the axis of the shaft upon which the taking-up wheel is fixed and which
is geared with the bottom cone shaft the arrangement being such as that the cone
can be raised and lowered or moved partly around the said axis without interfering.
with the gearing or with the parallelism of the cone axes. I may adopt any
suitable means for moving the cone. In a special arrangement a chain or equivalent.
appliance is attached to the frame carrying the cone and also to a wheel which is
fixed upon a horizontal shaft. The said shaft is connected by bevel gearing with a
second shaft extending above the clearers and upon this shaft is a suitable handle.
or hand-wheel whereby the horizontal shaft is turned at the required times to raise
the cone frame. The last named shaft may have two wheels so as to act upon both
ends of the cone frame. To regulate the tension of the strap I employ adjustable
stops on to which the cone frame is lowered. In one form of stop a screw works
in a bracket or fixing which is adapted to be fixed on the floor. The frame is
sustained by the said screws which when adjusted can be secured by means of lock
nuts. The strap is readily tightened by merely lowering the stops.

SAMUEL JOHNSON of Rochdale in the County of Lancaster Manager IMPROVE-
MENTS IN MACHINERY USED IN THE PREPARATION OF TEXTILE MATERIALS
My invention relates to the cones and connected parts of machinery used in the
preparation of cotton and fibrous materials for spinning as for example to slubbing,
intermediate and roving frames. In such machines one cone has to be moved
nearer to the other at times in order to slacken the belt. To enable this movement
to be effected I mount the movable cone in bearings in arms which are fitted to
turn upon the axis of the shaft upon which the taking up wheel is fixed and which
is geared with the bottom cone shaft the arrangement being such as that the cone
can be raised and lowered or moved partly around the said axis without interfering
with the gearing or with the parallelism of the cone axes. To regulate the tension
of the strap I employ adjustable stops which determine the point to which the cone
is to be lowered.
In
The cone a
In order that may invention may be fully understood I have attached hereto a
sheet of drawings made to a scale of about one and a half inches to the foot and
marked with letters of reference. Referring to the said drawings Fig: 1 represents
an end view and Fig: 2 a front elevation illustrating the application of my
invention to a frame or machine used in the preparation of textile materials.
the said Figs a is the ordinary upper cone and 6 the lower cone.
is mounted in the usual or in a'suitable manner. The bearings for the journals of
the cone b are formed in or attached to two arms o, c¹ which are mounted to turn
upon the same axis as the taking up wheel d. The said arms are both fixed by one
end to a shaft or bar c² or are cast or formed upon the said bar so that the parts
form a lever frame. The shaft c² is formed with journals which turn in bearings
in brackets e, e, or the said shaft may be tubular or be mounted upon a fixed shaft or
upon the taking up wheel shaft or the frame may be otherwise mounted to turn so
that when one of the arms is raised or lowered both arms move together so as to
preserve the parallelism of the axes of the cones." To the arm c is fixed one end of
a chain which passes over a chain wheel g and is secured by its other end to the
same arm so that when the wheel g is turned in one direction the frame c, c¹ and
as a consequence the cone b will be lifted and when the said wheel is turned in the
contrary direction the said parts will be lowered The wheel g is fixed upon a short
.shaft which is mounted in bearings in a bracket h and on the same shaft is fixed a
mitre or bevel wheel i. The wheel i gears with a wheel which is upon a vertical
shaft k which is mounted in a bearing formed in the bracket h. Upon the upper
end of the shaft k is fixed a handle whereby the said shaft can be turned in either
direction and also a ratchet wheel m. In the example this wheel m is formed with
two sets of teeth one right and the other left hand teeth, and two pawls engage
with the said teeth and can be used alternately so that the shaft can be kept from
turning in either direction as required. In the example when the said handle is
turned in the direction indicated by the arrow in the plan view Fig: 3, the lower
cone is raised the pawl to the left hand in the drawing preventing the return
movement of the shaft and thereby sustaining the cone in its higher position. On
the contrary when the said pawl is lifted out of gear and the shaft k is turned in
a direction contrary to the indication the frame c and the cone are drawn down the
right hand pawl acting to keep the cone down in its lower position. I make use
of the double ratchet and two pawls and the chain acting in either direction upon
the cone frame c in cases wherein the weight of the said frame and of the cone and
connected parts is not sufficient to render the cone belt sufficiently tight especially

page_text: in the cases wherein my invention is applied to long frames or otherwise I use the
said parts to obviate the necessity for adding weight to the cone frame but I do
not confine myself to the precise arrangement and may use ohly one holding pawl
and a chain acting only to lift the cone frame and I may use any suitable means
for lifting the cone frame at the required times. To limit the downward movements
of the cone frame I employ two adjustable stops or supports n, n, seen most clearly
in Fig: 4 which represents the cones and cone frame detached from the framing of
the machine. Each stop consists of a screw which engages with a screw thread
formed in a casting or in a nut or metal piece which is or may be fixed to the floor.
The screw is provided with a lock nut or with a locking part which keeps the
screw in its adjusted position. A downward projection on the outer end of each
arm of the cone frame rests upon the head or upper end of the screw of one of the
supports when the cone frame is lowered. If preferred the screw may work in a
thread formed in the arm and rest upon a metal plate or support upon the floor.
It will be seen that when the handle is acted upon to raise the cone b both ends of
the cone are raised in an equal degree so that the parallelism of the axes of the
two cones is maintained and also that by adjusting the stops or supports n the
degree of tightness of the driving belt can be regulated to a great nicety. If
preferred the shaft upon which the chain wheel g is fixed might be extended
towards the left in Figs 2 and 3 so as to carry a second chain wheel to act upon a
chain connected with the arm c so as to lift both arms together but if the two arms
are suitably connected together such additional parts will not be required.
Having now fully set forth and indicated the nature of my said invention and
the manner in which I carry the same into practical effect I would have it to be
understood that I claim :-
First. In machines of the kind herein indicated the combination of parts for
sustaining the lower cone and for raising, lowering and adjusting the height of the
same substantially as set forth and indicated hereinbefore and in and by the
accompanying drawings.
Secondly. The employment of a horizontal shaft provided with a chain wheel
and actuated by means of a vertical shaft and bevel gearing for raising and lowering
the frame in which the lower cone is mounted whereby I am enabled to maintain
the tension of the cone belt substantially as set forth and indicated.
Thirdly. The arms c, c', connected together or cast or formed in one piece turning
upon the axis of the taking up wheel and raising the bottom cone when acted upon
by a chain or equivalent appliance and the adjustable stops n substantially as and
for the purpose set forth and indicated.
And lastly. The adjustable screw stops n for sustaining the cone frame in its
lowest regulated position whereby the tension of the driving strap can be regulated
with nicety substantially as set forth and indicated.
In witness whereof I the said Samuel Johnson have hereunto set my hand and
seal this twenty-sixth day of February in the year of our Lord one thousand eight
hundred and eighty four
