We JOHN COOKE STAFFORD of the Tatton Mill, Ordsall Lane, Salford in the
County of Lancaster, General Manager and GRIMSHAW HEAP, of the same place,
Shed Manager do hereby declare the nature of said Invention for IMPROVED
MECHANISM FOR IMPARTING MOTION TO THE PRESSER OF SECTIONAL WARPING
MACHINES, to be as follows:-
The object of this Invention is to secure a uniform size of sections, and the
prevention of injury to the yarn by the presser bowl.
We attain this object in the following manner:- -We place a shaft parallel with
the section shaft supported by two bearings, which bearings are bolted to the sides
of the frame. On this shaft we place a slotted lever fastened to the said shaft by
set screws or keys or otherwise. This slotted lever is connected with the presser
by a connecting rod and an additional slotted lever which additional lever is
connected to another slotted lever (which carries the presser) on the presser.
bowl shaft.
The first named shaft is caused to turn slowly partly round, preferably by a lever
fastened to the said shaft and connected to a worin shaft by a worm bracket which
is caused to travel by the said worm shaft.
Motion is communicated to the worm shaft by a ratchet wheel which is driven
by a catch or pawl worked by a half moon on the section shaft. A balance wheel
with a handle is or may be fitted on the end of this worm shaft for the purpose of
turning back the presser at the beginning and end of each section.

Shed Manager, do hereby declare the nature of said Invention for IMPROVED

MACHINES, 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 this Invention is to secure a uniforın size of sections, and the
prevention of injury to the yarn by the presser bowl.
We attain this object in the following manner:-We place a shaft parallel with
the section shaft, supported by two bearings, which bearings are bolted to the sides
of the frame. On this shaft we place a slotted lever fastened to the said shaft by
set screws or keys or otherwise. This slotted lever is connected with the presser
by a connecting rod and an additional slotted lever, which additional lever is
connected to another slotted lever (which carries the presser) on the presser bowl
shaft. The first named shaft is caused to turn slowly, partly round preferably, by
a lever fastened to the said shaft and connected to a worm shaft by a worm.bracket
which is caused to travel by the said worm shaft.
Motion is communicated to the worm shaft by a ratchet wheel which is driven
'by a catch or pawl worked by a half-moon on the section shaft. A balance wheel
with a handle is or may be fitted on the end of this worm shaft for the purpose of
turning back the presser at the beginning or end of each section.

And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is an end elevation, Fig 2 a side elevation and Fig. 3 a plan of our
improved mechanism for imparting motion to the presser bowl of a sectional
warping machine.
In these views, a is the additional shaft which is parallel to the section shaft b
and to which is secured the slotted lever c connected by a link d and a slotted lever e
to the presser shaft fon which is fixed the lever g carrying the presser h. The
shaft a is caused to turn slowly partly round by the lever i secured to the shaft a
and connected to the worm shaft j by the worm bracket k, and also connected
by the forked lever to the boss of the friction pulley which is free to move
laterally on the shaft m' from which it receives its rotary motion: the friction
pulley bears against and drives the flange b' of the section shaft b and so gives
motion to the latter. Motion is given to the worm shaft j by the ratchet wheel n
which is driven by the catch or pawl o pivoted to the frame and actuated by a half.
moon or cam on the section shaft b (not shown in the Drawings).
If more convenient, motion may be communicated to the worm shaft j from the
section shaft b by securing a spur wheel to the former, which wheel gears into a
carrier wheel gearing into a ratchet wheel mounted on a stud secured to the frame
and driven by the catch or pawl o actuated by the half moon or cam on the section
shaft bp is the balance wheel fixed on the worm shaft j and provided with a
handle in order to turn back the worm shaft j before beginning a fresh section.
As the section shaft b revolves motion is given to the worm shaft j and
transmitted by the worm bracket k to the lever i; the shaft a is thus moved
slowly partly round and this motion is transmitted by the levers c, d and e to the
presser shaft f which thus gradually moves the lever g and presser h away from
the shaft b as the section fills.

page_text: Although we have shown and described our Invention as applied to a machine
in which the section shaft b is driven by a friction pulley we would have it clearly
understood that our Invention is equally applicable to machines in which the
section shaft is driven by gearing or otherwise.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed
We declare that what we claim is-
The combination and arrangement of parts forming the improved mechanism for
imparting a positive motion to the presser h from the section shaft b, substantially
in the manner and for the purposes herein set forth.
