"
PROVISIONAL SPECIFICATION left by the said Samuel Brooks, George
Harrison, and Thomas Goodbehere at the Office of the Com-
missioners of Patents, with their Petition, on the 17th May 1873.
We, SAMUEL BROOKS, of the Union Works, West Gorton, near
Manchester, in the County of Lancaster, Machine Maker, GEORGE
HARRISON, of the same Place, Manager, and THOMAS GOODBEHERE, of
the same Place, Foreman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING, AND
WINDING," to be as follows:-
Our Invention is applicable to the machines known as "ring and
traveller throstles and doublers," and it consists in an improved com-

page_text: bination of machinery for distributing the yarn on the spool or bobbin.
The ordinary heart or shaper acts on two levers as usual, and in each
lever is a screw the nut of which is connected to a chain passing over a
pulley; to this pulley is connected a second chain which is taken around
a pulley on the ordinary lifting shaft. The screw is turned partly round
at every revolution of the heart by a tumbler catch acting on a ratchet
wheel to which is fixed a change pinion taking into another change
pinion fixed on the screw. On commencing a set of cops the screw nut
is furthest from the fulcrum of the lever in order that the greatest lift
may be given to the copping rail, and every revolution or half revolution
of the heart reduces the lift, thereby building the cop with a taper or
cone at each end; or the screw may be in a quadrant gearing into a
wheel on the lifting shaft.
Another part of our Invention consists in an improved footstep for
upright spindles used in machines for spinning, doubling, and winding;
the spindle works in a footstep which is fixed in a chamber containing
the oil or other lubricant, and which enters the footstep through a hole
near the bottom, the chamber is closed by a lid.
The bolster for the spindles consists of a cast-iron tube with a counter-
sunk top and a recessed collar containing a flannel washer, the oil
passes from the recessed collar through a diagonal hole to the spindlo.

a plan of part of a ring and traveller throstle for spinning and doubling
constructed according to our improvements.
a is the ordinary heart or shaper which acts as usual on the two
levers b, b, and each lever is cast with a slot in which the screws c are
supported; on each screw c is a nut d, to which the chains e are
suspended, and the lower ends of these chains are taken partly round
and secured to the pulleys f; to these pulleys are also attached the
lower ends of the chains g, the upper ends whereof are secured to the
pulleys fixed to the ordinary lifting shafts i, to which the pulleys ; are
fixed, and the chains k secured to these pulleys are connected in the
ordinary manner to the usual lifting rails, one of which is shown to the
right-hand side of Fig. 1. To each screw c is fixed a spur pinion c¹ into
which gears the pinion / cast or fixed to the ratchet wheel F, the teeth
of which come in contact with the tumbler catch m at every vibration of
the levers b. The tumbler catches yield to allow the ratchet wheels to
pass during the descent of the levers b.
The mode of operation is as follows:-On commencing a set of cops
the screw nuts d are near the outer ends of the slots in the levers b, in
order that the greatest lift may be given to the copping rails and at
every upward motion of the levers 6 the ratchet wheels come in contact
with and are turned partly round by the tumbler catches m; the partial
rotary motion thus given to the ratchet wheels is communicated by the
pinions and c¹ to the screws c, thereby moving the nuts d slightly in
the direction of the arrows in Fig. 1. At the next vibration of the
levers 6 the action on the chains e, g, and k, and consequently on the
lifting rails will be reduced, and the action continues to decrease
gradually at every lift, thereby building cops with a taper or conc at
each end. The pinions 7 and c¹ can be changed for others having more
or less teeth in order to vary the action on the screws c according to the
count of yarn that is being spun.
On Sheet 2, Fig. 4 is an elevation, and Fig. 5 a plan of a modification
-

page_text: a is the usual heart or shaper acting on the levers b, b, which are
connected by means of the links e to the nuts & of the screws c; .but
these screws instead of being supported in the levers 6 as before described
are supported in the quadrants o, which gear into the pinions n on the
usual lifting shafts i. The ratchet wheels are fixed on the ends of the
screws c, and the tumbler latches m are placed in such a position that they
act on the said ratchet wheels when the segments o vibrate on their
fulcrum studs o². At the commencement of a set of cops the nuts d are
at the top of the screws c, and as the levers b vibrate they impart the
greatest motion to the lifting shafts and rails, as before described, and the
lift is gradually reduced as the cops are built by the descent of the
nuts d on the screws c.
Fig 6 represents a section of our improved footstep for upright
spindles used in machines for spinning, doubling, and winding; p is a
bush fitting into the footstep rail, the upper part of the bush p forms
a chamber to contain the oil or other lubricant; the brass footstep q is
fixed in the bush p and the lubricant is admitted to the spindle through
the holot in the footstep. The chamber in the bush p is closed by the
lid r. By this arrangement the flyings and other impurities are to
a great extent kept out of the lubricant, and the chamber containing
the lubricant can easily be cleaned out when the lid r is raised on the
spindle.
Fig. 7 is a section of our improved bolster for upright spindles used
in machines for spinning, doubling, and winding; 8 is a bush fixed in
the bolster rail; near the upper end of the bush is the chamber to contain
oil or other lubricant which is admitted to the spindle through the
diagonal hole t; the said hole slants downwards in order that the lubricant
which is raised by capillary attraction in the bush may not have a
tendency to escape upwards; the lubricant is filtered before it goes to the
spindles by passing through a flannel washer.
Having thus stated the nature of our Invention and described the
manner of performing the same, we declare that wo claim the improved
machinery shewn in Figs. 1, 2, 3, 4, and 5, for distributing the yarn on
the spools or bobbins of throstle frames as described.

Secondly. The improved footsep shewn and described in reference to

and Thomas Goodbehere have hereto set our hands and scals,
