IMPROVEMENTS IN SPINNING AND DOUBLING MACHINES
Year: 1885

page_text: We JAMES WHALEY SHEPHERD and WILLIAM AYRTON of the firm of Shepherd
and Ayrton of the Gore Brook Iron Works, Manchester in the County of Lancaster
Engineers and CHARLES SIDDALL in the employment of the said firm Mechanic do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN SPINNING
AND DOUBLING MACHINES" and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement and
accompanying drawings:-
Our invention relates principally to the machines used in the spinning and
doubling of cotton. We attach the thread board to arms which are fixed on
a shaft which is mounted in the roller stands or in brackets projecting therefrom
and we provide a handle to turn the said shaft whereby the thread board can be
turned up from end to end of the frame. The back roller slides in our improved
spinning frames are adjusted simultaneously by means of a shaft which extends
throughout the range of roller stands. The cap bar is hinged so that it can be
turned up and in spinning frames bearings for the front roller are formed in blocks
which are carried by the outer ends of the hinged cap bars and can slide to provide
for the back roller adjustment. A clearer board is hinged to the cap bar and can
be turned up for the removal of the fluff. The traverse bar or roving guide is
steadied and prevented from springing by means of anti-friction bowls. To more
effectually damp the yarn it is caused to make a turn or two or more turns around
a roller in the trough. We mount each spindle of a doubling machine in top and
footstep bearings in a bracket which is secured to the rail the wharve being between
these bearings and below the wharve we apply a half bearing to support the spindle
against the pull of the band. A bolster on the underside of the bracket projects
through the rail and forms an oil reservoir. The dirty oil from the footstep escapes
by a side opening and is conveyed into a drip cup which is screwed or secured to
the lower end of the bolster. The tube driver is formed with wings which have
a little spring or is split so that the tube is firmly gripped.
The nature of our Invention will be more clearly understood when reference is
had to the accompanying sheet of drawings wherein Fig. 1 represents a Side
Elevation and Fig. 2 a Front Elevation of a roller stand and connected parts
constructed in accordance with our Invention. In the said Fig. a. is a roller
stand b. is the thread board c. is the back roller slide d, is the cap bar and a, is the

page_text: thread clearer. Upon the said roller stand is cast a bracket or jaw f. which is
bored to receive a hinge shaft which extends through bearings in corresponding
brackets on all the stands on the frame side. Upon this shaft is fixed an arm h.
which in conjunction with corresponding arms which are fixed at intervals upon
the same shaft carries the thread board. Upon the said shaft is also fixed a handle
or lever i. and a ratchet wheel j with which engages a detent k. By acting upon
the said handle the thread board can be turned up from end to end of the frame so
as to raise all the thread guides out of the way with one movement of the hand.
The detent . sustains the thread board until the doffing is completed or as long as
may be desirable. By connecting the hinge shaft with the corresponding shaft on
the other side of the frame the thread boards on both sides are raised by the same
movement. In the examples the two shafts are provided with pulleys one of
which . appears in Fig. 2 these pulleys being connected together by means of
chains or bands. Other suitable means such as levers and connecting rods or racks
and pinions may be used for the purpose or if preferred the boards on the two sides
of the frame may be unconnected. It will be understood that the remaining roller
stands on the frame or on the same side of the frame are also formed or provided
with brackets to carry the shaft g. but only one stand say the end stand is or need
be provided with the parts i. j. k. and . In the back roller slide c. is fixed
a stud m. with which engages a forked lever n. which is fixed upon a shaft o.
which extends throughout the range of the roller stands on the frame side and is
mounted in bearings formed in the said stands. By turning the said shaft all the
back roller slides on the same side of the frame can be adjusted by one movement
of the hand. The said shaft may be actuated by means of a lever or hand wheel
or by means of a worm and wheel or by suitable gearing. The method of trans-
mitting motion from the shaft to the slides may be varied as for example cams or
excentrics may be used or spur pinions on the shaft may gear with racks upon the
slides. The cap bar d. is hinged at p. to the slide c. in order that it may be turned
up and as the rollers rest upon the metal at the bottoms of the bearing recesses
when the cap bar is raised the said rollers are at the same time raised from contact
with the bottom rollers so that the yarn or roving can be readily brought forward
between the top and bottom rollers. The drawings illustrate a construction
suitable for use in spinning frames. From the front end of the cap bar a finger cl
projects and upon this is mounted a block q. in which are formed the bearings for
the front top roller. A plan of the cap bar appears at Fig. 3 and an end view at
Fig. 4. The block q. is adjustable upon the said finger so as to permit of the back
rollers being adjusted at a less or greater distance from the front roller. When
the rollers have been adjusted the block q. is fixed by means of a set screw.
clearer board which we apply above the top rollers is represented by e.
is hinged at e¹ to the cap bar so that it can be quickly turned up for the removal
of the fluff and be turned back into its ordinary or working position. The
ordinary traverse bar is represented by r. This bar when at work has a tendency
to spring or vibrate. To check this and to steady the bar in its movements we
employ wheels which bear upon the bar as in the case of the wheel s. in Fig. 1.
Each wheel is mounted in a forked block which is secured to an arm t. which is
fixed to the roller stand and is adjustable so that the pressure of the wheel upon
the traverse bar can be regulated. The arrangement for damping the yarn is
illustrated by Fig. 5 wherein u. is a roller which revolves within a trough v. and
is kept in position by means of a bracket w. which is secured to the said trough.
We may cover the said roller with felt or other suitable absorbent fabric. The
yarn proceeds in the direction indicated and makes a complete turn around the
roller or two or more turns as found to be most desirable. The bracket i. is
formed with slots to receive the roller journals these slots being shaped to enable
the roller to be inserted and withdrawn. Our improved method of mounting
doubling spindles is illustrated by Fig. 6. A bolster x. is connected by means of
an arm with an upper bearing piece x the parts forming one casting. The said
bolster is bored to receive a footstep y. in which the lower end of the. spindle

screwed to receive a securing nut z. and a removable drip cup a¹. At the upper
end of the bore of the bolster is fixed a half bearing b¹ which sustains the spindle
against the pull of the band the direction of this strain being indicated by an
arrow. The upper end of the bolster is bell mouthed to facilitate the supplying
with lubricant. The space around the spindle will contain a supply of oil which
slowly works its way through the footstep bearing the dirty oil escaping through
a passage c in the footstep into the drip cup. The upper bearing piece is
bored to suit the spindle or is bushed as preferred. We prefer to apply the brake
represented in plan in Fig. 7 and which has been described in the specification of
our Letters Patent N° 8560 of the year 1884. The improved tube driver is
represented by . The tube fits upon wings 2 and the carrier is split or formed
with slots or saw gates between these wings so that they have an amount of
spring so as to hold the tube with an elastic grip.

Invention and in what manner the same is to be performed we declare that what
we claim is
