I WILLIAM TAYLOR of 19 Hill Street Oldham in the County of Lancaster
Engineer do hereby declare the nature of said Invention for IMPROVEMENTS IN
THE REGULATING MOTION OF LAP MACHINES FOR OPENING COTTON AND OTHER
FIBRES to be as follows:-
The object of my improvements is to make the regulating motion of a lap
machine more sensitive and to insure greater accuracy in the feed.
In carrying my invention into effect I employ the ordinary feed lattice, feed
rollers, pair of driving cones, and plate levers, each of which levers is pivoted to
the machine frame at one end and is supported in front upon a vertical rod or
shaft; each adjoining pair of rods rests at the bottom upon a balanced plate, and
all these balanced plates are supported either directly or indirectly on a knife edge
on one main or central support at the lower part of a vertical rod. Instead of
suspending this central support from a rocking shaft as now customary I suspend
the central support for all the rods and plates on the short end of a weighted lever
fulcrumed on a stationary knife edge secured to the frame. At the other end the
fulcrumed weighted lever is connected adjustably to the strap fork guide for
moving the belt on the driving cones and thus varying the speed at which the
machine is driven, whenever the plate levers are moved by variations in the
thickness of the lap passing between the plates and the feed roller.

I WILLIAM TAYLOR, of 19 Hill Street, Oldham, in the County of Lancaster,
Engineer do hereby declare the nature of said Invention for "IMPROVEMENTS IN
THE REGULATING MOTION OF LAP MACHINES FOR OPENING COTTON AND OTHER
FIBRES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my improvements is to make the regulating motion of a lap
machine more sensitive and to insure greater accuracy in the feed.
In carrying my Invention into effect I employ the ordinary feed lattice, feed
rollers, pair of driving cones, and plate levers, each of which levers is pivoted to
the machine frame at one end and is supported in front upon a vertical rod or
shaft; each adjoining pair of rods rests at the bottom upon a balanced plate and
all these balanced plates are supported either directly or indirectly on a knife edge
on one main or central support at the lower part of a vertical rod. Instead of
suspending this central support from a rocking shaft as now customary I suspend
the central support for all the rods and plates on the short end of a weighted lever
fulcrumed on a stationary knife edge secured to the frame.
At the other end the fulcrumed weighted lever is connected adjustably to the
strap fork guide for moving the belt on the driving cones and thus varying the
speed at which the machine is driven whenever the plate levers are moved by
variations in the thickness of the lap passing between the plates and the feed
'roller.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of Drawings, reference being had
to the figures and letters marked thereon.
Figure 1 is a back view and Fig. 2 a side view of part of a lap machine for
opening cotton and other fibres, enough only of the machine being shown to
illustrate the nature of my Invention.
In these views.-a is the feed lattice, shown only in dotted lines, Fig. 2, b the
feed regulating roller, on the shaft 6' of which is secured the worm wheel b³ driven
by the worm c fixed on the shaft of the cone d which is driven from the cone d¹ by
a strap e so that the speed of the roller b varies according to the position occupied
by the strap on the cones d d¹. The roller shaft b¹ transmits motion by gearing
(not shown) to the ordinary pair of feed rollers f so that the speed of the latter is
also governed by the position of the strap e. Each of the plate levers g is pivoted
at one end as usual on a shaft gl supported in suitable bearings carried by the
frame of the machine and the other end of each pivoted plate lever g is supported
on a vertical rod or shaft h. Each adjoining pair of vertical rods h rests at the
bottom upon a balanced plate i, each pair of plates i being supported upon a
balanced plate, and the pair of balanced plates rest upon a balanced plate 12
supported centrally on a knife edge j' formed on the lower part of a vertical rod or
hanger 1.

page_text: The foregoing description refers only to what are well known parts of the
machine. I will now proceed to describe the novel arrangement which constitutes
my Invention.
In the ordinary lap machine it is customary to suspend the aforesaid central
hanger ; from a rocking shaft connected to the strap fork guide but I dispense with
this rocking shaft and employ instead a weighted lever k, fulcrumed on a knife
edge formed on or secured to the machine frame. The short end of the lever k is
provided with a knife edge k¹ from which is suspended the vertical hanger ; which
may be adjusted by means of a screw and locknuts m. The lever k which is
weighted by means of the adjustable weight n is pivoted to one end of a lever o
provided with a long slot near the centre by means of which it is adjustably
fulcrumed on a stud o¹; this lever o is connected by a rod p to one end of a
balanced elbow lever q pivoted at q¹ and connected at the other end by a rod or
bar to the strap fork guide 8 by which the position of the strap e on the
cones d d' can be adjusted so as to vary the speed at which the feed of the
machine is driven. The rod p is made in two pieces the adjacent ends of which
have a right and a left hand screw thread respectively cut on them and are
connected by a nut p¹ so that the length of the rod p can be adjusted by turning
the nut p'.
Whenever the plate levers g are moved by variations in the thickness of the lap
passing between them and the feed regulating roller b, the vertical rods h and the
balanced plates are also moved, thus affecting the position of the fulcrumed lever k
which actuates, through its connections the rods o and p, elbow lever q, and bar r,
the strap fork guide s and so shifts the position of the strap e on the cones d d¹ and
varies the speed of the machine as required.
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-
1. In a lap machine for opening cotton and other fibres, the combination with
the pivoted plate levers, the vertical rods or shafts, the balanced plates supporting
the same, and an adjustable central support or hanger from which said plates
depend, of a fulcrumed weighted lever, connected adjustably to the strap fork
guide, substantially as herein set forth for the purposes specified.
2. The use and application in combination with the plate feed motion and other
parts of a lap machine, of the fulcrumed lever k, weighted and connected adjustably
to the strap fork guide, substantially in the manner and for the purposes herein
described and as illustrated by the Drawings annexed.
