Improvements in Converting Rotary into Reciprocating Motion.
1 JAMES WINDER, Junior Britannia Mills Whitehall Road Leeds Woollen Cloth
Manufacturer do hereby declare the nature of this invention to be as follows:-
:-
An endless running Cord Belt or chain is put round a pulley or pullies keyed to a
revolving Shaft and also passed over another pulley or pullies running loosely on
a spindle carried in a frame placed a convenient distance apart to allow the Machinery
to be traversed backwards & forwards between the pullies.
The outgoing and incoming sides of the cord belt or chain are each passed over
and under a pair of single or double pullies carried on spindles fixed some distance
apart to a bracket or arm of the Machinery to be reversed.
The reversing motion is obtained by means of a Lever attached to the arm or
bracket, which is shifted by stop peices placed at either end of traverse and acting
through suiteable Mechanism alternately grips or releases the outgoing Cord belt or
chain, or the incoming side of the cord belt or chain, and traverses the Machinery
cither way to any distance required without any change in the length or running
of the cord belt or chain. What I claim as new and my invention is the alternate
gripping and releasing of the incoming & outgoing sides of the Cord belt or chain
for Reversing the Action of Machinery in Motion.

Improvements in Converting Rotary into Reciprocating Motion.
1, JAMES WINDER Junior, Britannia Mill, Whitehall Road, Leeds, Cloth
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
An endless running Cord Belt or Chain is put round a single or double grooved
pulley or pullies, keyed to, any convenient revolving shaft, and also put round another
single or double grooved pulley or pullies, running freely on a spindle in a frame,
placed such a convenient distance apart, as will allow of the Machinery to he traversed
backwards and forwards between these pullies.
The outgoing and incoming sides of the Cord between the pullies, are each
alternately passed over and under a pair of single or double grooved pullies carried
on spindles, fixed some distance apart to a Bracket or Arm of the Machinery to be
traversed.
The reversing motion is obtained by means of a Lever attached to the Bracket or
arm which can be shifted by stopping peices placed at either end of traverse, and
acting through suiteable Mechanism alternately gripping & releasing the pullies on
the outgoing and incoming sides of the Cord Belt or chain and thereby holding or
releasing the said Cord Belt or chain with the pullies, and traversing the Machinery
in either direction to any distance required, without changing the length, or direction
of the running, of the Cord Belt or chain.
Having described in general terms the nature of my Invention, I detail the same
more fully with reference to the accompanying Drawings.

Sheet 1. represents the general arrangements as fitted to a "Carding Machine" for
the working backwards and forwards of a Blaymire Feed," or any Machinery
requiring a similar reciprocating motion.
Sheet 2 represents in detail the mechanism I prefer, to grip and release the pullies,
over and under which the incoming and outgoing sides of the endless running Cord
Belt or Chain is put.
The letters of reference indicate the same parts in both Sheets.
An endless running Cord Belt or Chain A with any number of guide pullies B
where necessary, is put round a single or double grooved pulley or pullies C, keyed
to any convenient revolving Shaft.
The incoming and outgoing sides of A, as shewn by the arrows, are each passed
over and under the single or double grooved pullies D D and E E respectively, as
shewn by the dotted lines. These pullies revolve on spindles fitted into the Arm or
Bracket F of the Machinery to be traversed, and from there A is carried over a
single or double grooved pulley or pullies G, running freely on a spindle in
frame H provided with a screw I, to take up any slack in A, and placed such
a convenient distance apart as will allow of the Machinery, to be traversed backward
and forwards the required distance between the pullies C and G.

page_text: The gripping and releasing of the pullies D D and E E alternately, is obtained by
means of the bent Lever L, which works freely on a pin M, and is connected by the
pin N on its shorter arm to the double ended pawl O, which is provided with teeth
at each end, to engage with the circular rings of teeth, cast on to the backs of the
pullies D D and E E respectively, and kept in a central line between them by steady
pins at top & bottom, and made of a length sufficient to clear either pullies, when
the Lever L is in its middle position.
The bent spring S, is fixed to the bottom of the Arm F, to keep the Lever L when
in contact with the pullies D D or E E, from shaking itself free, by any vibration of
the Machinery.
The manner in which the working of this Invention is performed is shewn as
follows.
The Lever L being shifted so as to gear the teeth of the pawl O with the teeth of
the pullies D D, these pullies are held fast, and the incoming side of the running
cord A passed round them also, and the Arm F is drawn towards the pulley C, untill
the lever L comes in contact with the stop peice U, and is shifted so as to release
the pawl O from contact with the pullies D D, and made to gear with the pullies E E,
which are now held fast, and the outgoing side of the running cord A passed round
them also, and the Arm F is drawn towards the pulley G untill the lever L comes
in contact with the stop peice T, when it is again shifted. The pullies E E and that
side of the cord A put round them are now released, and the pullies D D, and
that side of the cord A put round them are now held fast, and the Arm F is drawn
again towards the pulley C, untill the lever L comes in contact with the stop peice U,
when it is shifted, and so long as the pulley C is kept in motion, the reciprocating
action on the Arm F and connected Machinery is maintained, through the alternate
gripping and releasing of the pullies DD and E E, and the outgoing and incoming
sides of the running Cord A put round them.
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
The alternate gripping and releasing of the incoming and outgoing sides of a
continuous running Cord Belt or chain passing round pullies, for converting Rotary
into Reciprocating Motion as shewn.
